Detailed Implementation
[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0019] Obviously, many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0020] Please see Figure 1-3This utility model provides an anti-reverse device for a connecting rod assembly bushing, including a base frame 1. Two symmetrical elastic mechanisms are fixedly connected to the bottom of the inner cavity of the base frame 1, and a sliding plate 2 is fixedly connected to the top of both elastic mechanisms. The sliding plate 2 is slidably disposed inside the base frame 1. A positioning plate 16 is fixedly connected to the top of the base frame 1, and two symmetrical positioning posts 3 are fixedly connected to the top of the sliding plate 2. A pressure plate 4 is fixedly connected to the top of the two positioning posts 3, and a groove is formed on the top of the pressure plate 4. Two symmetrical fixing plates 26 are fixedly connected to the bottom of one side of the pressure plate 4. A fixed plate 26 is rotatably connected between the two fixed plates 26, and a knob 24 is fixedly connected to one end of the fixed plate 26. Two symmetrical square sliding openings are provided inside the groove. Threaded sleeve blocks 27 are threaded onto both ends of the bidirectional threaded rod 25. A first clamping plate 9 is fixedly connected to the top of each of the two threaded sleeve blocks 27. An installation opening is provided on one side of the groove. A placement groove 11 and a placement round opening are provided on the outer surface of the positioning plate 16. T-shaped grooves 23 are provided on both sides of the placement round opening, and two symmetrical clamping plates 9 are fixedly connected to one side of each of the two T-shaped grooves 23. Each of the two first springs 19 has a sliding block 20 fixedly connected to one end, and a sliding insert 18 fixedly connected between the two sliding blocks 20. A limit plate 17 and a clamping plate 21 are fixedly connected to both ends of the sliding insert 18, respectively. A side plate 5 is fixedly connected to the top of the positioning plate 16, and a top plate 6 is fixedly connected to the top of the side plate 5. A cylinder 7 is fixedly inserted into the bottom of the top plate 6, and a pressing plate 8 is fixedly connected to the bottom of the cylinder 7. By placing a connecting rod bushing inside the placement opening, the bushing is clamped by the two elastic clamping plates 21. Then, on the pressure plate 4... The connecting rod is placed inside, and the mounting hole of the connecting rod is aligned with the mounting opening. Then, by rotating the knob 24, the threaded sleeve 27 rotates, causing the two threaded sleeves 27 to drive the two first clamping plates 9 to clamp the connecting rod. Subsequently, when the cylinder 7 extends, the pressing plate 8 presses down on the pressure plate 4 and the connecting rod as a whole. Thus, the two positioning pins 3 and the two elastic mechanisms make the pressure plate 4 and the clamped connecting rod fall stably, thereby pressing the connecting rod bushing into the mounting opening of the connecting rod. This avoids the reverse connection problem of the bushing, and the bushing installation is stable and simple to operate.
[0021] It should be noted that the elastic mechanism mentioned above includes a fixed sleeve 13, which is fixedly connected to the bottom of the inner cavity of the base frame 1. A second spring 28 is fixedly connected to the bottom of the inner cavity of the fixed sleeve 13. A pressure plate 15 is fixedly connected to the top of the second spring 28. A connecting post 14 is fixedly connected to the top of the pressure plate 15. The top of the connecting post 14 is fixedly connected to the bottom of the positioning plate 16. The pressure plate 15 is slidably disposed inside the fixed sleeve 13. The outer surface of the pressure plate 15 is in contact with the inside of the fixed sleeve 13. When the pressure plate 4 descends, the sliding plate 2 slides inside the base frame 1, thereby using the sliding plate 2 to press down the two connecting posts 14. The elasticity of the two second springs 28 supports and elastically resets the downward pressure of the pressure plate 4.
[0022] To facilitate the stable clamping of the connecting rod bushing, one side of each of the two clamping plates 21 is flush with the outer surface of the round opening, and the two sliding blocks 18 are respectively slidably inserted into the interior of the two T-shaped grooves 23, with the two sides of the two sliding blocks 18 respectively fitting against one end of the two T-shaped grooves 23.
[0023] In order to provide downward pressure space for the two threaded sleeves 27, the two fixing plates 26 and one threaded sleeve 27 are slidably placed inside the placement groove 11, and the tops of the two positioning pins 3 are slidably inserted into the interior of the positioning plate 16.
[0024] To facilitate the smooth and stable sliding of the sliding plate 2, the base frame 1 is U-shaped, and both sides of the U-shaped inner cavity of the base frame 1 are provided with insertion grooves 12. Both sides of the sliding plate 2 are fixed with insertion blocks 29, and the two insertion blocks 29 are slidably disposed inside the insertion grooves 12, with the sides of the two insertion blocks 29 respectively fitting against the sides of the two insertion grooves 12.
[0025] To facilitate the sliding stability of the two first clamping plates 9, both first clamping plates 9 are slidably disposed inside the groove, and one end of each of the two first clamping plates 9 is in contact with one side of the inner cavity of the groove. The two threaded sleeves 27 are slidably disposed inside the two square sliding openings, and the two sides of the two threaded sleeves 27 are in contact with the two sides of the two square sliding openings.

[0027] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
[0028] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
