DETAILED DESCRIPTION

It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

As shown in Fig. 1-Fig. 5, a rod angle adjustment and locking device of the present invention comprises a fixing member 10, a direction adjustment disk 20, a locking member 30, and a sleeve member 40. The fixing member 10 comprises a base and a disk body 13. The base comprises a connecting rod 11 and a sleeve screw 12. The bottom end of the fixing member 10 is a sleeve screw 12. The sleeve screw 12 is an internal thread structure with an opening at the bottom end, which can be screwed to the top end of the base connecting rod for fixing. The top end of the sleeve screw 12 is connected to the bottom end of the connecting rod 11. The connecting rod 11 is a retractable structure. The disk body 13 is installed on the top of the connecting rod 11. The disk body 13 is provided with a cylindrical structure whose axial direction is perpendicular to the connecting rod 11, which is used to fit the sleeve 40. A bolt hole 132 is provided at the center of the other end of the disk body 13. The bolt hole 132 corresponds to the locking piece 30. The outer side of the bolt hole 132 extends in the opposite direction of the disk plug 131 to form an annular gasket 133. The outer side of the annular gasket 133 abuts against the locking piece 30. The annular gasket 133 cooperates with the bolt hole 132 to limit and fix the locking piece 30.

The direction adjustment disk 20 includes a disk base 21 and a limiting cylinder 22. The surface of one side of the disk base 21 is recessed inward to form a circular groove for a nut sleeve 23. The disk base 21 is axially provided with a base through hole, i.e., the nut sleeve 23. The two opposite sides are respectively provided with through holes in the same straight line, i.e., the limiting cylinder 22. The limiting cylinder 22 is a hollow cylindrical structure.

The sleeve 40 is an integrally formed three-way structure, including a screw-on part and a sleeve part. The screw-on part is a truncated cone structure with an internal threaded through hole 42 on the axis. The truncated cone structure allows the end with a smaller diameter to be screwed and force applied, while the other end generates a larger friction force, which is more conducive to tightening and fixing. The sleeve part is a spherical structure with a rod body through hole 41 on the axis. The axes of the sleeve part and the screw-on part are perpendicularly connected to each other, and the internal threaded through hole 42 is connected to the rod body through hole 41. In order to reduce friction during rotation, the sleeve part is provided with a groove along the circumference of the rod body through hole. Accordingly, the nut sleeve of the spherical structure can be provided with a spherical concave part that can cooperate with the sphere.

The socket connection 40 is used for the socket connection of the rod body and the screw connection of the locking member. The rod body through hole 41 allows the rod body to pass through the socket connection part. The internal threaded through hole 42 of the screw connection part is screwed with the screw of the locking member 30. The length of the screw is greater than the axial length of the internal threaded through hole 42 of the screw connection part. The front end passes through the screw connection part and abuts against the rod body of the socket connection part, so that the rod body and the screw connection part are relatively fixed.

The locking member 30 is a bolt with a hand wrench.

The bolts pass through the bolt holes 132 of the sleeve 13 in turn and are screwed together with the threaded through holes 42 of the sleeve connector 40 inside the sleeve 13. The bottom of the bolts abuts against the rod body to achieve fixed locking of the overall structure. The bolts are loosened to allow the rod body and the steering adjustment disk to move. The rod body can be displaced radially and can also be displaced angularly by rotating the steering adjustment disk.

When in use, firstly, the fixing member 10 is screwed to the top of the base connecting rod through the bottom sleeve screw 12, and then one end of the rod body through hole 41 opened by the sleeve 40 is installed in the nut sleeve and communicated with the limit tube 22, and the rod body is inserted from one end of the limit tube 22 of the direction adjustment disk 20, through the rod body through hole 41 and out from the other end of the limit tube 22, and the screwed part of the sleeve 40 is placed in the sleeve 13, and the locking member 30 is screwed into the sleeve 13 of the fixing member 10 through the bolt hole 132, and screwed with the sleeve 40 in the sleeve 13, and the bottom end of the locking member 30 is made to abut against the side of the rod body by screwing in the locking member 30 until it is fixed. If the height or telescopic length of the rod body needs to be adjusted, the height can be adjusted by unscrewing the locking member 30, and then rotating the angle of the direction adjustment disk 20 to achieve the height adjustment, and the radial adjustment of the rod body can be achieved by adjusting the extension length of the rod body at both ends of the limit tube 22.

Example 1

The present embodiment provides an application of the present invention in the field of surgical lights, including a fixing member 10, a direction adjustment disk 20, a locking member 30, and a sleeve member 40.

The screw of the locking member 30 passes through the sleeve 13 from one side of the annular gasket 133, and the rod body through hole 42 of the sleeve member 40 corresponds to the through hole 23 of the limit tube 22. The lamp holder rod body connected at one end is inserted from the limit tube 22 of the direction adjustment disk 20. Insert, pass through the rod body through hole 41 and pass out from the other end of the limit tube 22, the rod body fixes the direction adjustment disk 20 and the socket 40 relatively, moves the fixed direction adjustment disk 20 and the socket 40, puts the threaded end of the socket 40 into the sleeve 13, screws in the locking member 30 to make it corresponding to the internal threaded through hole 42, and continues to screw in the locking member 30 so that it abuts against the side of the lamp holder connecting rod 50 passing through from the bottom end of the socket 40. After tightening, the overall locking device can be fixed. The threaded structure realizes the locking function, the direction adjustment disk 20 realizes 360° rotation, the sleeve 13 realizes the overall fixation, the sleeve realizes the direction fixation of the lamp holder connecting rod, and the cooperation of the fastening screw and the socket nut makes one side of the lamp holder connecting rod abut against the inner wall of the sleeve, which increases the overall stability.

The present invention has the following beneficial effects: the angle and radial direction of the rod body can be adjusted in a double manner through one adjustment, which is suitable for the use environment of a lightweight single-arm rod body structure; secondly, the overall component structure is simple, which is convenient for installation and disassembly; in addition, the technology of the present invention can also be used for fixing cantilever structures in other fields. Since the locking component has no special design requirements for the structure of the rod body, there is no restriction on the choice of angle and extension length, which can be selected arbitrarily. The present invention can also be used in combination with CN107588061 in the background technology to achieve the effects of shock absorption and two-way adjustment.
