Description

Technical Field

[0001] This utility model relates to the field of wear-resistant bushing technology, specifically to a wear-resistant bushing. Background Technology

[0002] Wear-resistant bushings are accessories used on the outside of mechanical parts to achieve functions such as sealing and wear protection. They refer to rings that act as gaskets.

[0003] For example, a wear-resistant bushing with authorization announcement number "CN202040211U" has a wear-resistant groove designed in this utility model. This groove adds an oil storage groove between the wear-resistant bushing and the release shaft, which can increase the lubricating oil content and extend the lubrication time, effectively solving the problems of abnormal noise and increased clutch pedal force. At the same time, the wear-resistant groove design of this utility model has a simple structure, is easy to process, and does not affect production costs. However, in the use of the wear-resistant bushing, the length of the bushing is fixed and secured by a buckle at the front end, while the position of the ring on the other side cannot be adjusted. This prevents the wear-resistant bushing from being fixed in position with the outer sleeve, causing the connecting sleeve between the wear-resistant bushing and the outer wall to move left and right, resulting in instability and shaking during use, affecting the normal use of the wear-resistant bushing. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of wear-resistant bushings shaking during use, which affects their normal use, and to propose a wear-resistant bushing.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wear-resistant bushing is designed, comprising a first bushing and a first groove. The inner wall of the first bushing is machined with multiple first grooves. A control structure is connected to the rear end face of the first bushing. Straight plates are fixed to the front slots on the left and right sides of the first bushing, respectively. A round rod is connected to the front of the control structure.

[0007] Preferably, the control structure includes a second bushing and a thread, the front side of the second bushing is fixedly connected to the rear end face of the first bushing, the outer wall of the second bushing is threaded, and the outer wall of the thread is threaded with a ring.

[0008] Preferably, the front side of the ring is fixedly connected to the rear end face of the plurality of round rods.

[0009] Preferably, the inner wall of the second bushing is machined with a plurality of second grooves, the front of the second grooves being connected to the rear of the first grooves.

[0010] Preferably, the outer wall of the first bushing is machined with multiple round openings.

[0011] Preferably, a wedge block is fixed to the outer front end of the straight plate.

[0012] The wear-resistant bushing proposed in this utility model has the following advantages: by controlling the ring in the structure to rotate forward on the outer wall of the thread, the round rod moves forward until the ring drives the round rod to abut against the rear of the collar, thus completing the installation of the first bushing and the second bushing. The fixed position can be adjusted according to the installed collar to ensure the stability of the wear-resistant bushing, avoid the wear-resistant bushing from shaking during use, and ensure the normal use of the wear-resistant bushing.

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] Example 1: Please refer to Figure 1-4 In this embodiment, a wear-resistant bushing includes a first bushing 1 and a first groove 7. The inner wall of the first bushing 1 is machined with a plurality of first grooves 7. The first bushing 1 is made of stainless steel. A control structure 2 is connected to the rear end face of the first bushing 1. Straight plates 5 are fixedly connected to the front slots on the left and right sides of the first bushing 1, respectively. A round rod 3 is connected to the front face of the control structure 2.

[0020] The control structure 2 includes a second bushing 201 and a thread 202. The front side of the second bushing 201 is fixedly connected to the rear end face of the first bushing 1. The material of the second bushing 201 is stainless steel. The outer wall of the second bushing 201 is machined with a thread 202. A ring 203 is threadedly connected to the outer wall of the thread 202. The ring 203 rotates back and forth under force through the outer wall of the thread 202. The front side of the ring 203 is fixedly connected to the rear end face of multiple round rods 3.

[0021] By controlling the ring 203 in structure 2 to rotate forward on the outer wall of thread 202, the round rod 3 is moved forward until the ring 203 drives the round rod 3 to abut against the rear of the collar, thus completing the installation of the first bushing 1 and the second bushing 201. The fixed position can be adjusted according to the installed collar to ensure the stability of the wear-resistant bushing, avoid shaking during use, and ensure normal use of the wear-resistant bushing.

[0022] The inner wall of the second bushing 201 is machined with multiple second grooves 8. The front of the second groove 8 is connected to the rear of the first groove 7. The outer wall of the first bushing 1 is machined with multiple round openings 4. The round blocks 4 facilitate the filling of lubricating oil into the bushing. The outer front end of the straight plate 5 is fixed with a slanted block 6.

[0023] Working principle:

[0024] When using this bushing, when the inclined block 6 on the outer side of the straight plate 5 contacts the inside of the collar, the inclined block 6 is forced to bend the straight plate 5 inward until the inclined block 6 disengages from the inside of the collar. The straight plate 5 then springs back, causing the inclined block 6 to lock onto the front end of the collar. Then, the ring 203 rotates forward on the outer wall of the thread 202, thereby moving the round rod 3 forward until the ring 203 drives the round rod 3 to abut against the rear of the collar, completing the installation of the first bushing 1 and the second bushing 201. The fixed position can be adjusted according to the installed collar to ensure the stability of the wear-resistant bushing. Lubricating oil can be injected into the first bushing 1 and the second bushing 201 through the round opening 4. The first groove 7 and the second groove 8 on the inner wall can store excess lubricating oil, extending the lubrication time of the wear-resistant bushing.

[0025] Example 2: Please refer to Figure 1-4 In this embodiment, the control structure 2 also includes curved blocks 2a1, the inner sides of which are fixedly connected to the upper and lower sides of the ring 203 respectively.

[0026] Working principle:

[0027] By pressing the curved blocks 2a1 on the upper and lower sides with your fingers, you can make the ring 203 rotate on the outer wall of the thread 202. The curved blocks 2a1 can increase the friction between the fingers and make it easier to rotate the ring 203.

[0028] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
