In the embodiment of the present application, the driving rod 3 can be screwed with the socket module 2, and the driving rod 3 is rotatably connected with the mounting base 1, so that when the user does not operate the driving rod 3, the position between the driving rod 3 and the mounting base 1 It can be relatively fixed, and when the user operates the driving rod 3 , the driving rod 3 can rotate along its own axis, and the socket module 2 can move along its screw thread engaged with the driving rod 3 . Alternatively, the driving rod 3 can be threadedly engaged with the inner wall of the receiving chamber 11, and the driving rod 3 is rotatably connected with the socket module 2, so that when the user rotates the driving rod 3, the driving rod 3 can drive the socket module 2 to move along the socket module 2 together. The threaded movement of the driving rod 3 engaged with the mounting base 1 . Alternatively, the driving rod 3 can be threadedly engaged with the socket module 2 and the inner wall of the accommodating chamber 11 , so that when the user rotates the driving rod 3 , the driving rod 3 can drive the socket module 2 to move together through screw transmission.

Optionally, in order to improve the stability of the fixing of the driving rod 3 when the user does not operate the driving rod 3, the driving rod 3 can be rotatably connected with the mounting base 1, and the driving rod 3 can be screwed with the socket module 2; or, the driving rod 3 can be connected with the The socket module 2 is rotatably connected, and the driving rod 3 is threadedly engaged with the inner wall of the accommodating cavity 11 .

And optionally, as shown in FIG. 1 , the driving rod 3 may have an operating part 31, the operating part 31 is exposed to the opening 111, and when the operating part 31 is operated, the driving rod 3 is driven to rotate, and then the socket module 2 is driven by the driving rod 3 Move along the depth direction of the accommodating chamber 11.

The socket provided in the embodiment of the present application, through the rotational connection between the driving rod 3 and the mounting base 1 (socket module 2) and the threaded fit with the socket module 2 (mounting base 1), when the driving rod 3 rotates, It can drive the socket module 2 to move along the depth direction of the accommodating cavity 11 , for example, the user rotates the driving rod 3 clockwise or counterclockwise, and the socket module 2 can move toward or away from the opening 111 . It can be seen that the socket provided by the embodiment of the present application can realize the arbitrary adjustment of the position of the socket module 2 in the accommodation cavity 11 .

Further, in the socket provided by the embodiment of the present application, the operating part 31 of the driving rod 3 is exposed to the opening 111 of the accommodation cavity 11, so that the user can adjust the position of the socket module 2 in the accommodation cavity 11 from the front of the socket (that is, the opening 111 side). The location and operation method are relatively simple. Moreover, even after the socket is connected to the wall, the position of the socket module 2 can still be adjusted according to power plugs of different sizes.

For ease of description, the structure of the socket will be described below by taking the driving rod 3 rotatably connected to the mounting base 1 and the screwing of the driving rod 3 with the socket module 2 as an example.

In the embodiment of the present application, when an external force is applied to the operating part 31 to cause the drive rod 3 to rotate, the socket module 2 can move along its screw thread engaged with the drive rod 3, or the rotation of the socket module 2 can be restricted, so that The socket module 2 can only move along the depth direction of the accommodating cavity 11 .

Optionally, as shown in FIG. 1 , the shape of the accommodating cavity 11 matches the shape of the socket module 2 and is configured to limit the rotation of the socket module 2 .

Specifically, both the shape of the socket module 2 and the shape of the accommodating cavity 11 can be substantially square, so that the socket module 2 is difficult to rotate in the accommodating cavity 11 , and thus the problem of wire entanglement caused by the rotation of the socket module 2 can be avoided. Moreover, the socket module 2 and the receiving chamber 11 can be clearance-fitted so as to facilitate the socket module 2 to move in the receiving chamber 11 along the depth direction of the receiving chamber 11 . Alternatively, a matching structure may be provided between the socket module 2 and the inner wall of the accommodating cavity 11 to limit the rotation of the socket module 2 . Exemplarily, the socket module 2 may have a first matching portion, and the inner wall of the accommodating cavity 11 may have a second matching portion, one of the first matching portion and the second matching portion may be a locking block, and the other may be a locking block or Any of the card slots. The rotation of the socket module 2 is limited by the contact stop between the blocks, or the limited fit of the blocks or the slots. In this case, the shape of the socket module 2 and the accommodating cavity 11 may be approximately cylindrical.

In the embodiment of the present application, in order to minimize the adjustment range required by the user, the driving rod 3 can rotate around an axis parallel to the depth direction of the first accommodation cavity 11, so that the user can rotate the driving rod 3 in a small range. The socket module 2 is effectively driven to move along the depth direction of the accommodating cavity 11 .

Moreover, the "rotational connection" in the embodiment of the present application can be understood as the rotation of a component (such as the driving rod 3 ) around its own axis. In order to effectively drive the socket module 2 to move along the depth direction of the accommodating cavity 11 through screw fit, the position of the driving rod 3 in the depth direction of the accommodating cavity 11 can be limited, and corresponding components can be provided on the mounting base 1 to limit the driving rod. 3 positions. In other embodiments, the driving rod 3 can also move to a certain extent along the depth direction relative to the inner wall of the accommodating cavity 11, as long as the driving rod 3 can be driven The socket module 2 only needs to move along the depth direction of the accommodating cavity 11 .

That is to say, the driving rod 3 can be screwed with the socket module 2, and the position of the driving rod 3 in the depth direction of the accommodating cavity 11 can be limited, so that the driving rod 3 can drive the socket module 2 along the depth of the accommodating cavity 11 when the driving rod 3 rotates. direction to move.

Various matching structures can be adopted between the driving rod 3 and the mounting base 1 to allow the driving rod 3 to rotate and to limit the position of the driving rod 3 in the depth direction of the accommodating cavity 11 . Exemplarily, the driving rod 3 and the mounting base 1 can be rotationally connected by using a matching structure of a limiting groove and a protrusion, or a matching structure of a hole and a shaft. And in order to facilitate the rotation of the driving rod 3 , the limiting groove can be designed as an arc-shaped groove matching the rotation track of the driving rod 3 .

Optionally, as shown in FIG. 2 , the mounting base 1 has a mounting hole 121 extending along the depth direction of the accommodating cavity 11 . A part of the driving rod 3 is rotatably located in the mounting hole 121 .

The inner wall of the accommodating cavity 11 may extend inwardly (near the central axis direction of the accommodating cavity 11 ) out of the mounting portion 12 , and the mounting hole 121 may be located on the mounting portion 12 . The part of the driving rod 3 exposed from the mounting hole 121 can be screwed to the socket module 2 .

Further, as shown in FIG. 2 , a side of the installation hole 121 close to the central axis of the accommodation chamber 11 (away from the inner wall of the accommodation chamber 11 ) may have a defective portion 122 . The driving rod 3 can be fitted into the installation hole 121 through the defective portion 122 .

The mounting portion 12 can be disposed in the receiving cavity 11 on a side close to the opening 111 , and the socket module 2 can be threadedly connected to the driving rod 3 under the mounting portion 12 (a side away from the opening 111 ). Alternatively, the mounting portion 12 may also be disposed on a side away from the opening 111 in the accommodating cavity 11 , and the socket module 2 may be threadedly connected to the driving rod 3 above the mounting portion 12 (a side close to the opening 111 ). Alternatively, as shown in FIGS. 2 and 7 , when the depth of the accommodating cavity 11 is small, the mounting portion 12 may be disposed on the side of the accommodating cavity 11 away from the opening 111 , and the socket module 2 may be installed The bottom part 12 is threadedly connected with the driving rod 3 , and provides guidance for the movement of the socket module 2 through the screw fit between the driving rod 3 and the socket module 2 .

In the embodiment of the present application, the socket may only include one driving rod 3, and the part of the socket module 2 that is not connected to the driving rod 3 may abut against the inner wall of the accommodating cavity 11, so as to fix the position of the socket module 2 and prevent the socket module from 2 offset occurs.

Optionally, as shown in FIGS. 1 and 3 , the socket may include at least two driving rods 3 , and the at least two driving rods 3 may be arranged at intervals along the peripheral edge of the socket module 2 .

FIG. 3 shows that the socket includes two driving rods 3 as an example. In other embodiments, the socket can also include more than two driving rods 3, and a plurality of driving rods 3 can be arranged at intervals around the peripheral edge of the socket module 2, so that the driving rods 3 can form multiple points for the socket module 2. Support, so that the stability of the installation of the socket module 2 can be improved. In some embodiments, the distance between two adjacent driving rods 3 along the outer edge of the socket module 2 is the same.

Optionally, as shown in FIG. 3 , there are two driving rods 3 , and the two driving rods 3 are arranged symmetrically with respect to the central axis of the socket module 2 . The two driving rods 3 can reduce the number of driving rods operated by the user, and at the same time can more reliably fix the position of the socket module 2 .

As above, the shape of the socket module 2 can be substantially square, and the shape of the accommodating cavity 11 is adapted to the shape of the socket module 2 to limit the rotation of the socket module 2 in the accommodating cavity 11 . In addition, in order to install the driving rod 3 in the accommodating cavity 11 , a part of the outer wall of the socket module 2 can be cut off to fit the driving rod 3 .

Optionally, as shown in FIG. 3 , the edge of the socket module 2 may have at least one first corner portion 22, and the first corner portion 22 may extend along the depth direction of the accommodating cavity 11 and be recessed toward the central axis of the socket module 2. . Each driving rod 3 can be threadedly engaged with a first corner portion 22 respectively.

That is to say, the cross section of the socket module 2 parallel to the opening 111 may be a rectangle with at least one missing corner, and the driving rod 3 may be located at the missing corner.

Exemplarily, as shown in FIG. 2 , in order to facilitate the rotation of the driving rod 3 around its own axis and to be threadedly engaged with the socket module 2 , the driving rod 3 may be cylindrical as a whole. Correspondingly, the notch (the first corner portion 22 ) may be an arc concave toward the inside of the socket module 2 (ie, a direction close to the central axis of the accommodation cavity 11 ). Threads can be provided on the concave surface of the missing corner, so as to realize the screw fit between the socket module 2 and the driving rod 3 . That is, the threads on the socket module 2 can be arranged along the depth direction of the receiving cavity 11 .

In addition, as can be seen from FIG. 3 , in order to facilitate the user to take power through the jack 21 on the socket module 2 , the jack 21 is often arranged at the middle of the surface of the socket module 2 . Therefore, in the socket provided by the embodiment of the present application, the driving rod 3 is arranged at the missing corner of the socket module 2 (that is, the corner of the socket module 2 that is generally square), which can ensure the connection between the driving rod 3 and the socket to a certain extent. 21, so as to avoid affecting the user's access to electricity through the jack 21, which helps to reduce the size of the socket.

In some embodiments, when the number of driving rods 3 is three or more, each driving rod 3 may be disposed at the corresponding first corner 22 of the socket module 2 . The number of first corners 22 in the socket module 2 should not be less than the number of driving rods 3 .

When the socket includes two or more driving rods 3, the user can adjust the driving rods 3 one by one, and finally adjust the socket module 2 to a suitable position, and at the same time adjust the surface where the socket 21 in the socket module 2 is located to the same position as The openings 111 are parallel.

Optionally, as shown in FIG. 4 , the socket may also include a connecting piece 4, at least two driving rods 3 are respectively connected to the connecting piece 4, and the connecting piece 4 may be configured to drive at least two driving rods 3 to rotate synchronously. .

By setting the connecting piece 4 that can drive at least two driving rods 3 to rotate synchronously, when the user needs to adjust the position of the socket module 2, only one of the driving rods 3 can be rotated to drive the whole socket module 2 to move, which further simplifies the user operation , and the stability of the movement of the socket module 2 can be guaranteed to a certain extent. In other words, by setting the connecting piece 4 that can be transmitted, all the driving rods 3 in the socket can be associated, the user can select one of the driving rods 3 as the active part, and the rest of the driving rods can be used as follower parts to rotate and follow the active part synchronous rotation.

The connecting piece 4 is mainly used to realize the transmission between the multiple driving rods 3 , and in some embodiments, a matching structure of a belt and a pulley can be used between the connecting piece 4 and the multiple driving rods 3 .

Further optionally, as shown in FIG. 4 and FIG. 5 , the connecting member 4 can be an annular rack, and the annular rack can be in a tensioned state, and the driving rod 3 is engaged with the annular rack.

By engaging the driving rod 3 and the connecting part 4 together, the stability of the cooperation between the driving rod 3 and the connecting part 4 can be improved, and the connecting part 4 can be prevented from being detached from the driving rod 3 .

In the embodiment of the present application, the size of the socket module 2 can be determined according to its power supply and a suitable power plug. In order to reduce the size of the socket as much as possible, the size of the connector 4 in the depth direction of the receiving cavity 11 can be approximately the same as the size of the socket module 2 in the depth direction. In this case, the ring rack needs to be looped on the socket module 2 outside.

Optionally, as shown in FIG. 4 and FIG. 5 , the portion where at least one driving rod 3 in the socket engages with the ring rack can protrude from the outer surface of the socket module 2 . After the annular rack ring is set on at least two driving rods 3, there may be a certain gap between the inner side of the annular rack and the outer wall of the socket module 2, thereby preventing the socket module 2 from hindering the ring to a certain extent. The rack turns.

Specifically, as shown in FIGS. 3 and 4 , the size of the first corner 22 in the socket module 2 can be smaller than the size of the driving rod 3 , so that after the driving rod 3 is assembled to the first corner 22 , the Another part of the driving rod 3 can protrude relative to the socket module 2 . In other words, the projection of the driving rod 3 in the direction of the opening 111 may at least partially exceed the projection of the socket module 2 in the direction of the opening 111 .

In the embodiment of the present application, as mentioned above, the socket module 2 may be square as a whole, and the number of driving rods 3 may be smaller than the number of first corners 22 in the socket module 2, so optionally, as shown in FIG. 5 , the socket may further include at least one rolling member 5 connected to the socket module 2 , and the rolling member 5 can rotate around a first axis, and the first axis is parallel to the depth direction of the accommodating cavity 11 . Each rolling element 5 can be respectively located between two adjacent driving rods 3 , and each rolling element 5 can respectively abut against the ring rack.

Optionally, as shown in FIG. 3 , the socket module 2 has a second corner portion 23 , the second corner portion 23 is located between two adjacent driving rods 3 , and the rolling member 5 is located at the second corner portion 23 .

In the embodiment of the present application, the second corner portion 23 may be other corner portions extending along the depth direction of the receiving cavity 11 in the socket module 2 except the first corner portion 22 . It can be understood that the corner is formed by the intersection of two faces in the socket module 2 .

As shown in FIG. 5 , at the corner where the socket module 2 is not provided with the drive rod 3 , the corner of the socket module 2 may abut against the ring rack, thus hindering the rotation of the ring rack, which in turn increases the user’s ability to rotate the drive rod 3 resistance. Based on this, by adding a rolling member 5 at the corner of the socket module 2 where the drive rod 3 is not provided, and abutting the rolling member 5 against the side of the ring rack away from the inner wall of the accommodating cavity 11, the impact on the ring rack can be reduced. Rotational hindrance.

Specifically, as shown in FIG. 5 , the outer edge of the rolling element 5 may be substantially aligned with the outer edge of the socket module 2 where the rolling element 5 is located. The socket module 2 may be provided with an installation slot opening toward the ring rack, and two fixed shafts may extend from the installation slot. The rolling member 5 can be a roller, and after the roller is fixed in the installation groove through two fixed shafts, the roller can rotate around a first axis parallel to the depth direction of the accommodating cavity 11 . In other embodiments, the rolling element 5 can also be a ball.

It should be noted that, in other embodiments, the driving rod 3 can be rotatably connected to the socket module 2 using the same or similar structure. Exemplarily, the outer wall of the socket module 2 may have a mounting portion, and the above mounting hole is opened on the mounting portion, and the driving rod 3 can rotate in the mounting hole. In addition, the socket module 2 can also adopt the same or similar structure to avoid hindering the movement of the connecting member 4 .

The connecting portion 33 can be connected with the connecting piece 4 , and the connecting portion 33 can be located between the shaft portion 32 and the threaded portion 34 .

The maximum distance between the outer edge of the connecting portion 33 and the central axis of the driving rod 3 may be smaller than the maximum distance between the outer edge of the threaded portion 34 and the central axis of the driving rod 3 . That is, the size of the connecting portion 33 may be smaller than that of the threaded portion 34 .

As shown in FIG. 2 above, a mounting portion 12 can be formed on the mounting base 1, and the mounting portion 12 has a mounting hole 121, and the shaft portion 32 in the driving rod 3 can be fitted to the mounting hole 121 to define the driving rod 3. The position in the depth direction of the accommodating chamber 11. The connecting part 33 is arranged between the rotating shaft part 32 and the threaded part 34 with a larger size, so that the connecting piece 4 matched with the connecting part 33 is equivalent to being limited in the limiting space formed by the threaded part 34 and the mounting part 12 , can effectively prevent the connecting piece 4 from detaching from the driving rod 3 .

The outer diameter of the shaft portion 32 may be smaller than the outer diameter of the threaded portion 34 . The shaft portion 32 with a smaller diameter is fitted into the mounting hole 121 , so that the design size of the mounting hole 121 can be reduced, thereby helping to reduce the size of the socket.

The rotating shaft portion 32 , the connecting portion 33 and the threaded portion 34 may all be substantially cylindrical, wherein the connecting portion 33 may be provided with a plurality of grooves for engaging with the ring rack. The outer wall of the shaft portion 32 may have an assembly surface 321 , and the assembly surface 321 may be parallel to the axis of the shaft portion 32 . By providing the fitting surface 321 on the shaft portion 32 , the shaft portion 32 can be conveniently assembled into the installation hole 121 through the defect portion 122 .
