Description

Universal sleeve

This creation is related to handicrafts, especially a universal socket.

Socket tools are widely used in automobile repair, mechanical assembly, home repair and other fields. Sockets can quickly and conveniently turn various fasteners such as bolts. However, traditional sockets only have a single working direction, so they often cannot meet the needs of use. Therefore, the industry later developed a universal socket. The design of the two joints can be relatively offset so that the socket can be extended into a variety of different environments. Therefore, it is widely loved by the public. For example, the universal socket disclosed in Taiwan Patent I724957 belongs to this category.

However, the universal sleeve of the above-mentioned patent has many problems, for example but not limited to, the processing is complicated, the processing cost is high, the polygonal head is easy to wear and become round and can no longer be used, and the C buckle used to prevent the rotating joint from easily blocking the swing range of the rotating joint.

Therefore, it is necessary to provide a novel and advanced universal sleeve to solve the above-mentioned problems.

The main purpose of this invention is to provide a universal sleeve that can be easily and quickly assembled and has better rotation stability and rotation range.

To achieve the above-mentioned purpose, the present invention provides a universal sleeve, comprising: a sleeve seat, a rotating member and a plurality of stopping members. The cartridge seat comprises a main body and a first connecting portion, the first connecting portion is arranged on the main body, the main body defines an axial direction and a radial direction, the main body surrounds an internal space and an opening that are connected to each other, an inner wall surface of the main body is concavely provided with two sets of connection grooves along the radial direction, and each of the sets of connection grooves extends along the axial direction; the rotating member comprises an inserting portion, two convex portions and a second connecting portion, the inserting portion can be movably accommodated in the internal space, the two convex portions protrude from the inserting portion and can be movably inserted in the two sets of connection grooves, and the second connecting portion is connected to the inserting portion and protrudes out of the opening; the plurality of stoppers are convexly arranged on the inner wall surface and are in an interference configuration with the inserting portion in the axial direction.

The following is merely an example to illustrate possible implementations of the present invention, but it is not intended to limit the scope of protection for the present invention. The "one" or "at least one" preceding the terms mentioned in the text does not limit the quantity, and it can also be "plural" according to needs. This change in quantity is also within the scope of protection, which should be stated in advance.

Please refer to Figures 1 to 6, which show an embodiment of the present invention. The universal sleeve of the present invention includes: a sleeve seat 1, a rotating member 3 and a plurality of blocking members 4.

The cartridge seat 1 includes a body 2 and a first connection portion 27. The first connection portion 27 is provided on the body 2. The first connection portion 27 is a polygonal hole for plugging the driving head of a pneumatic or electric wrench. The body 2 defines an axial direction 71 and a radial direction 72. The body 2 encloses an internal space 21 and an opening 22 that are connected to each other. An inner wall surface 23 of the body 2 is concavely provided with two group connection grooves 25 along the radial direction 72. Each group connection groove 25 extends along the axial direction 71.

The rotating member 3 includes a plug-in portion 32, two protrusions 35 and a second connecting portion 33. The plug-in portion 32 can be movably accommodated in the internal space 21. The plug-in portion 32 is spherical in this embodiment. The two protrusions 35 protrude from the plug-in portion 32 and are movably inserted into the two assembly grooves 25. The protrusions 35 can move relatively in the assembly grooves 25 with the movement of the plug-in portion 32. The groove wall of the assembly groove 25 can provide additional lateral supporting force to the protrusions 35 so that it can have better stability during use. The second connecting portion 33 is connected to the plug-in portion 32 and protrudes out of the opening 22. The second connecting portion 33 is a polygonal protrusion in this embodiment and can be inserted into various adapters such as sleeves.

The plurality of stoppers 4 are protruded from the inner wall surface 23 and are interferingly disposed with the plug-in portion 32 in the axial direction 71 . The plurality of stoppers 4 can stop the plug-in portion 32 from different positions, thereby effectively preventing the rotating member 3 from being separated from the cartridge seat 1 .

Preferably, the universal sleeve further includes an elastic member 6, which is accommodated in the internal space 21 and elastically abuts between an inner bottom wall 24 of the body 2 and the plug-in portion 32; wherein the inner bottom wall 24 is laterally connected to the inner side wall 23. The elastic member 6 can push the rotating member 3 toward the plurality of blocking members 4, thereby generating a clamping force so that the rotating member 3 can be stably positioned at the rotated position for use.

The rotating member 3 further includes a main body 31 and a pin 34. The main body 31 includes the second connecting portion 33 and the plug-in portion 32 connected to each other. The pin 34 passes through the plug-in portion 32, and the two ends of the pin 34 protrude from the plug-in portion 32 to form two protrusions 35. This two-piece assembly method can simplify the processing difficulty and production cost. It can be understood that the pin 34 further includes a middle section 36 connected between the two protrusions 35. Preferably, the middle section 36 is buried in the plug-in portion 32, and a non-slip structure 37 is provided at the middle section 36, which can greatly improve the combination stability of the pin 34 and the plug-in portion 32.

In this embodiment, the two sets of connection grooves 25 are symmetrically arranged, and each set of connection grooves 25 includes a straight line segment 251 and an arc segment 252. One side of the straight line segment 251 is connected to the opening 22, and the other side of the straight line segment 251 is connected to the arc segment 252. The design of the arc segment 252 can further provide a margin space for the protrusion 35, so that the rotating member 3 can have a wider swing angle.

Preferably, when the extension direction of the two protrusions 35 is perpendicular to the axial direction 71, each of the blocking members 4 and each of the protrusions 35 are at least partially overlapped in the radial direction 72. This position configuration can ensure that the rotating member 3 has a larger range of motion when swinging.

It is worth mentioning that each of the blocking members 4 does not protrude into the assembly slot 25. In other words, each of the blocking members 4 will not block the protrusion 35. In this way, the protrusion 35 can protrude from the opening 22, and the rotating member 3 can also have a larger swing range.

In more detail, the body 2 further defines a circumferential direction 73, the inner wall surface 23 further has an annular groove 26 extending along the circumferential direction 73, the annular groove 26 is connected to the two connecting grooves 25, and the plurality of stoppers 4 are accommodated in the annular groove 26 and partially protrude from the annular groove 26 in the radial direction 72. In more detail, each of the stoppers 4 is in an arc-shaped strip shape, and the cross-sectional profile of each of the stoppers 4 is circular. Each of the stoppers 4 is continuously interfering with the plug-in portion 32 at multiple locations in the circumferential direction 73; wherein, the linear diameter of each of the stoppers 4 is smaller than the radius of the protrusion 35.

In this embodiment, the number of the plurality of stoppers 4 is two, and the two stoppers 4 are spaced apart in the circumferential direction 73 to jointly define two avoidance areas 5, and the size of each avoidance area 5 in the circumferential direction 73 is at least not less than the size of each assembly groove 25 in the circumferential direction 73, so that the protrusion 35 can protrude from the opening 22 through the avoidance area 5.
