Technical Field
[0001] The utility model relates to the technical field of bearing bushes, in particular to a bearing bush structure which is convenient to disassemble. Background Technique
[0002] The bearing bush is the part that contacts the journal of the sliding bearing, and its shape is a semi-cylindrical surface in the shape of a tile, which is very smooth. It is usually made of wear-resistant materials such as bronze and antifriction alloy, but in special cases, materials such as wood, engineering plastics or rubber can also be used. The design of the bearing bush aims to reduce friction through its smooth surface and appropriate lubrication method. Although it is called a "tile", in fact, its function is similar to that of a rolling bearing, which protects the journal from wear by reducing friction and keeps the machine running normally at the same time.
[0003] During the installation process of two bearing bushes, bolts are often used for fixation. When the bearing bushes are worn out subsequently, the bearing bushes need to be disassembled. All bolts need to be removed with the help of external tools to disassemble the two bearing bushes. Sometimes the bolts are prone to rust or slipping of the threads, so the disassembly of the bolts is rather troublesome, which makes the disassembly of the bearing bushes rather troublesome and takes a lot of time. Therefore, the utility model provides a bearing bush structure which is convenient to disassemble. Content of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the utility model provides a bearing bush structure which is convenient to disassemble, and is used to solve the problems put forward in the above background technique.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A bearing bush structure which is convenient to disassemble, including an upper bearing bush and a lower bearing bush. An upper mounting seat is fixedly installed on the surface of the upper bearing bush. An insertion block is fixedly installed on the front side of the upper mounting seat. A fixing groove is opened at the top of the insertion block. A lower mounting seat is fixedly installed on the surface of the lower bearing bush. A slot is opened at the rear side of the lower mounting seat. A storage groove is opened at the top of the lower mounting seat, and the storage groove is communicated with the slot. A fixing plate is fixedly installed inside the storage groove. A first elastic component is arranged at the bottom of the fixing plate. A fixing block is arranged at the bottom of the fixing plate through the first elastic component. A pulling plate is arranged at the top of the fixing plate through the first elastic component. A limiting groove is opened at the front side of the pulling plate. A second elastic component is arranged at the top of the lower mounting seat. A limiting block and a moving plate are arranged at the top of the lower mounting seat through the second elastic component.
[0007] Preferably, the first elastic component includes a first spring disposed at the bottom of the fixed plate. The bottom end of the first spring is fixedly installed with a movable plate. The movable plate is slidably connected to the storage groove and fixedly connected to the fixed block. A first movable rod is fixedly installed on the top of the movable plate. The first movable rod is slidably connected to the fixed plate and fixedly connected to the pull plate.
[0008] Preferably, the second elastic component includes a mounting plate disposed on the top of the lower mounting seat. A second spring is fixedly installed on the rear side of the mounting plate. The second spring is fixedly connected to the limiting block. A second movable rod is slidably connected inside the mounting plate. The second movable rod is fixedly connected to both the limiting block and the movable plate.
[0009] Preferably, a handle is fixedly installed on the front side of the movable plate. The handle is made of a metal material.
[0010] Preferably, the fixed block has a triangular structure and is made of a metal material. The fixed block is inserted into the fixed groove.
[0011] Preferably, the insertion block is adapted to the insertion slot, and the limiting block is adapted to the limiting slot.
[0012] Preferably, the number of the second springs is multiple, and the multiple second springs are arranged in an array. The second movable rod is located inside the second spring.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0014] 1. For the easily detachable bearing bush structure, during disassembly, the movable plate and the limiting block move forward to separate from the limiting slot. Then, the pull plate is pulled upward to compress the first elastic component, causing the fixed block to move upward to separate from the fixed groove. Subsequently, the insertion block is pulled out of the insertion slot, and the disassembly of the upper bearing bush and the lower bearing bush can be completed. The goal of more conveniently completing the disassembly of the upper bearing bush and the lower bearing bush is achieved. It avoids the phenomenon that the upper bearing bush and the lower bearing bush are fixed by bolts, which makes the disassembly rather troublesome, and reduces the time required for the disassembly of the upper bearing bush and the lower bearing bush.
[0015] 2. For the easily detachable bearing bush structure, during installation, move the moving plate and the limiting block forward to a suitable position to compress the second elastic component. Then, bring the upper bearing bush close to the lower bearing bush so that the insertion block is inserted into the insertion slot. During this process, the insertion block will squeeze the fixing block, causing the fixing block to move upward and compress the first elastic component. When the upper mounting seat and the lower mounting seat come into contact, at this time, the acting force generated by the first elastic component just makes the fixing block move downward and insert into the fixing groove to limit the insertion block. Subsequently, the acting force generated by the second elastic component can make the limiting block insert into the limiting groove, making it more convenient to install the upper bearing bush and the lower bearing bush. Moreover, when the limiting block inserts into the limiting groove, it can limit the pull plate, thereby facilitating the limitation of the fixing block and making it not easy for the fixing block to separate from the fixing groove, so that the upper bearing bush and the lower bearing bush are fixed more firmly.

[0022] Refer to Figures 1-4, A bearing bush structure that is easy to disassemble, including an upper bearing bush 1 and a lower bearing bush 2. An upper mounting seat 3 is fixedly installed on the surface of the upper bearing bush 1. A plug block 4 is fixedly installed on the front side of the upper mounting seat 3. A fixing groove 5 is opened at the top of the plug block 4. A lower mounting seat 6 is fixedly installed on the surface of the lower bearing bush 2. A slot 7 is opened at the rear side of the lower mounting seat 6. A storage groove 8 is opened at the top of the lower mounting seat 6, and the storage groove 8 is communicated with the slot 7. A fixing plate 9 is fixedly installed inside the storage groove 8. A first elastic component is arranged at the bottom of the fixing plate 9. A fixing block 12 is arranged at the bottom of the fixing plate 9 through the first elastic component. The fixing block 12 is triangular in structure and is made of metal material. The fixing block 12 is inserted into the fixing groove 5. When the plug block 4 is inserted into the slot 7, the plug block 4 will squeeze the inclined surface of the fixing block 12, which can make the fixing block 12 move upward automatically, so that the plug block 4 can be inserted more conveniently. A pull plate 14 is arranged at the top of the fixing plate 9 through the first elastic component. A limiting groove 15 is opened at the front side of the pull plate 14. A second elastic component is arranged at the top of the lower mounting seat 6. A limiting block 18 and a moving plate 20 are arranged at the top of the lower mounting seat 6 through the second elastic component. The plug block 4 is adapted to the slot 7, and the limiting block 18 is adapted to the limiting groove 15. The first elastic component includes a first spring 10 arranged at the bottom of the fixing plate 9. The bottom end of the first spring 10 is fixedly installed with a movable plate 11. The movable plate 11 is slidably connected with the storage groove 8, and the movable plate 11 is fixedly connected with the fixing block 12. A first movable rod 13 is fixedly installed at the top of the movable plate 11. The first movable rod 13 is slidably connected with the fixing plate 9, and the first movable rod 13 is fixedly connected with the pull plate 14. When the first spring 10 is compressed and loses the limit on the first spring 10, the acting force generated by the compression of the first spring 10 will make the fixing block 12 move downward, so that the fixing block 12 can be inserted into the fixing groove 5 more conveniently, and thus the plug block 4 can be limited more conveniently. The second elastic component includes a mounting plate 16 arranged at the top of the lower mounting seat 6. A second spring 17 is fixedly installed at the rear side of the mounting plate 16. The second spring 17 is fixedly connected with the limiting block 18. A second movable rod 19 is slidably connected inside the mounting plate 16. The second movable rod 19 is fixedly connected with both the limiting block 18 and the moving plate 20. The number of the second springs 17 is multiple, and the multiple second springs 17 are arranged in an array. The second movable rod 19 is located inside the second spring 17. Through the arrangement of the multiple second springs 17, the second spring 17 as a whole has better elasticity, and the second spring 17 is located outside the second movable rod 19, so that when the second spring 17 is compressed, it will not bend. A handle 21 is fixedly installed on the front side of the moving plate 20. The handle 21 is made of metal material. Through the second elastic component, a backward acting force can be given to the limiting block 18, so that the limiting block 18 can be inserted into the limiting groove 15 more conveniently, thus facilitating the limitation of the pull plate 14, so that the fixing block 12 is not easy to separate from the fixing groove 5, and thus the upper bearing bush 1 and the lower bearing bush 2 are fixed more firmly.For the easily detachable bearing bush structure, during disassembly, the moving plate 20 and the limiting block 18 are moved forward to separate from the limiting groove 15. Then, the pulling plate 14 is pulled upward, causing the first elastic component to be compressed, making the fixing block 12 move upward to separate from the fixing groove 5. Subsequently, the inserting block 4 is pulled out of the inserting slot 7, and the disassembly of the upper bearing bush 1 and the lower bearing bush 2 can be completed. The goal of more conveniently completing the disassembly of the upper bearing bush 1 and the lower bearing bush 2 is achieved, avoiding the phenomenon that the disassembly is rather troublesome due to the use of bolts to fix between the upper bearing bush 1 and the lower bearing bush 2, and reducing the time required for the disassembly of the upper bearing bush 1 and the lower bearing bush 2.
[0023] During use: Pull the handle 21 forward, causing the moving plate 20 to move forward, the second movable rod 19 to move forward, the limiting block 18 to move forward, and the second spring 17 to be compressed until the limiting block 18 moves forward to a suitable position. Move the upper bearing bush 1 close to the lower bearing bush 2, and insert the inserting block 4 into the inserting slot 7. During this process, the inserting block 4 will squeeze the fixing block 12, causing the fixing block 12 to move upward, the movable plate 11 to move upward, the first spring 10 to be compressed, the first movable rod 13 and the pulling plate 14 to move upward. When the upper mounting seat 3 and the lower mounting seat 6 come into contact, at this time, just by the acting force generated by the compression of the first spring 10, the movable plate 11, the fixing block 12, the first movable rod 13, and the pulling plate 14 move downward, causing the fixing block 12 to insert into the fixing groove 5. At the same time, release the handle 21. By the acting force generated by the compression of the second spring 17, the limiting block 18 can be made to insert into the limiting groove 15, and the installation of the upper bearing bush 1 and the lower bearing bush 2 can be completed. When disassembly is required, pull the handle 21 forward, causing the limiting block 18 to move forward to separate from the limiting groove 15. Then, pull the pulling plate 14 upward, causing the first movable rod 13, the movable plate 11, and the fixing block 12 to move upward, making the fixing block 12 separate from the fixing groove 5. Subsequently, the inserting block 4 can be pulled out of the inserting slot 7, and the disassembly of the upper bearing bush 1 and the lower bearing bush 2 can be completed.
[0024] In summary, for the easily detachable bearing bush structure, during disassembly, the moving plate 20 and the limiting block 18 are moved forward to separate from the limiting groove 15. Then, the pulling plate 14 is pulled upward, causing the first elastic component to be compressed, making the fixing block 12 move upward to separate from the fixing groove 5. Subsequently, the inserting block 4 is pulled out of the inserting slot 7, and the disassembly of the upper bearing bush 1 and the lower bearing bush 2 can be completed. The goal of more conveniently completing the disassembly of the upper bearing bush 1 and the lower bearing bush 2 is achieved, avoiding the phenomenon that the disassembly is rather troublesome due to the use of bolts to fix between the upper bearing bush 1 and the lower bearing bush 2, and reducing the time required for the disassembly of the upper bearing bush 1 and the lower bearing bush 2, thus solving the problems raised in the above background technology.
