Each first stabilizing rod is fitted with a first spring. The adjustment groove is provided with a first sliding plate that can slide along it. The first sliding plate is slidably sleeved on the two first stabilizing rods, and its front end is connected to the ends of the two first springs. A first wedge block is fixedly provided at the front end of the first sliding plate, with the inclined surface of the first wedge block facing forward; a push block is fixedly connected to the side of the first sliding plate, and the push block passes through a through hole opened on the side wall of the connecting rod and extends to the outside; The connecting rod has a through groove on one end face near the connecting seat that communicates with the adjusting groove, and the first wedge block can partially extend out of the through groove.

[0006] Preferably, a locking groove is fixedly provided on the side end face of the movable ring, and a sliding groove is provided inside the locking groove; A second stabilizing rod is fixedly installed inside the slide groove, and a second sliding plate that can slide along the slide groove is installed inside the slide groove. The second sliding plate is movably sleeved on the second stabilizing rod. A second spring is sleeved on the second stabilizer bar. One end of the second spring acts on the inner wall of the groove, and the other end acts on the second sliding plate, so that the second sliding plate has an outward movement tendency. A second wedge block is fixedly provided at the front end of the second sliding plate, and the second wedge block has an inclined outer surface that matches the inclined surface of the first wedge block.

[0007] Preferably, a connecting rod is rotatably engaged at the top of the locking groove, and the bottom end of the connecting rod extends into the interior of the locking groove and is fixedly connected to an eccentric wheel; The top of the connecting rod extends to the outside of the locking groove and is fixedly connected to an adjustment knob.

[0008] Preferably, the adjustment knob has a locking hole; The sidewalls of the locking groove and locking hole are provided with internal threads and are threadedly connected to a positioning bolt.

[0011] Preferably, the outer peripheral surface of the adjustment knob is provided with anti-slip protrusions.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This quick-release anti-loosening connecting rod bushing structure, after the bushing is installed between the connecting rod and the movable ring, the operator rotates the movable ring to close the connection between the movable ring and the connecting rod. Then, the operator pushes the push block, causing the first wedge block on the first sliding plate to extend through the through groove and insert into the locking groove opened in the movable ring. The second wedge block at the front end of the second sliding plate has an inclined surface that matches the first wedge block. Therefore, when the first wedge block is inserted into the locking groove, the second wedge block will move aside. After the first wedge block is fully inserted into the locking groove, the second wedge block will rebound under the action of the second spring, thereby restricting the first wedge block and locking the movable ring.

[0013] 2. This quick-release and anti-loosening connecting rod bushing structure allows for precise adjustment of the eccentric wheel via an adjustable knob. This eccentric wheel then presses against the second sliding plate, thereby restricting or releasing the first wedge block. This ensures a stable connection between the moving ring and the connecting rod. The anti-slip protrusions on the adjusting knob prevent slippage during rotation. Furthermore, the threads on the inner walls of the locking groove and locking hole facilitate the installation of positioning bolts, which then secure the adjusting knob, providing secondary restriction to the moving ring and enhancing its reliability.

[0014] 3. This quick-release and anti-loosening connecting rod bushing structure uses two second locking teeth on the locking washer to interlock by pressing against each other. Then, the first locking teeth on the locking washer contact the outer wall of the bottom locking groove of the positioning bolt. Therefore, when there is vibration, this can make good contact with it. At the same time, when there is vibration, the interlocking can effectively prevent the positioning bolt from falling off. Therefore, it can prevent loosening when used under vibration. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Please refer to Figures 1-6 for a quick-release and anti-loosening connecting rod bushing structure. One end of the connecting rod 1 is fixedly provided with a connecting seat 2, and a movable ring 3 is rotatably installed inside the connecting seat 2. The connecting rod 1 has an adjustment groove 4 inside, and two first stabilizing rods 5 are fixedly installed in the adjustment groove 4. Each first stabilizing rod 5 is fitted with a first spring 6. The adjustment groove 4 is provided with a first sliding plate 7 that can slide along it. The first sliding plate 7 is slidably sleeved on the two first stabilizing rods 5, and its front end is connected to the end of the two first springs 6. A first wedge block 8 is fixedly provided at the front end of the first sliding plate 7, and the inclined surface of the first wedge block 8 is provided facing forward; a push block 9 is fixedly connected to the side of the first sliding plate 7, and the push block 9 passes through the through hole opened on the side wall of the connecting rod 1 and extends to the outside; The connecting rod 1 has a through groove 10 on one end face near the connecting seat 2, which communicates with the adjusting groove 4, and the first wedge block 8 can partially extend out of the through groove 10.

[0019] Specifically, after the bushing 25 is installed between the connecting rod 1 and the movable ring 3, the operator rotates the movable ring 3 to close the connection between the movable ring 3 and the connecting rod 1. Then, the operator pushes the push block 9 to extend the first wedge block 8 on the first sliding plate 7 through the through groove 10 and insert it into the locking groove 11 opened in the movable ring 3. Since there are two first stabilizing rods 5 installed in the adjusting groove 4, the first sliding plate 7 can maintain stability during sliding. When the first wedge block 8 is locked by the second wedge block 16, the first spring 6 in the adjusting groove 4 is in a compressed state. When the operator releases the restriction on the first wedge block 8, the first spring 6 will return to its original position, thereby causing the first wedge block 8 to retract into the adjusting groove 4. Therefore, it is easier for the operator to operate. At the same time, only the push block 9 needs to be pushed to lock the connection between the connecting rod 1 and the movable ring 3, which makes it easy for the operator to operate with one hand.

[0020] In the embodiment: a locking groove 11 is fixedly provided on the side end face of the movable ring 3, and a sliding groove 12 is provided inside the locking groove 11; A second stabilizing rod 13 is fixedly installed in the slide groove 12, and a second sliding plate 14 that can slide along the slide groove 12 is installed in the slide groove 12. The second sliding plate 14 is movably sleeved on the second stabilizing rod 13. A second spring 15 is sleeved on the second stabilizer 13. One end of the second spring 15 acts on the inner wall of the slide groove 12, and the other end acts on the second sliding plate 14, so that the second sliding plate 14 has an outward movement tendency.

[0021] Specifically, the sliding groove 12 opened in the locking groove 11 allows the second sliding plate 14 to slide within it, thereby locking or unlocking the first wedge block 8. The two second stabilizing rods 13 installed in the sliding groove 12 can keep the second sliding block stable during movement. The second spring 15 extends when it avoids the first wedge block 8. After the first wedge block 8 is fully inserted into the locking groove 11, the avoidance of the second wedge block 16 is completed, and the second spring 15 will drive it to reset, thereby restricting the first wedge block 8.

[0022] In this embodiment: a second wedge block 16 is fixedly provided at the front end of the second sliding plate 14, and the second wedge block 16 has an inclined outer surface that is adapted to the inclined surface of the first wedge block 8.

[0023] Specifically, the second wedge block 16 at the front end of the second sliding plate 14 is provided with an inclined surface that matches the first wedge block 8. Therefore, when the first wedge block 8 is inserted into the locking groove 11, the second wedge block 16 will avoid it. Then, when the first wedge block 8 is fully inserted into the locking groove 11, the second wedge block 16 will rebound under the action of the second spring 15, thereby restricting the first wedge block 8 and locking the movable ring 3.

[0024] In this embodiment: a bushing 25 is provided between the connecting rod 1 and the movable ring 3; Both the movable ring 3 and the bushing 25 are provided with a connected liquid inlet hole 26.

[0025] Specifically, the fluid inlet hole 26 connected to the connecting rod 1 and the bushing 25 allows lubricant to enter the bushing 25 through it, thereby improving the lubrication effect.

[0026] Working principle: After the bushing 25 is installed between the connecting rod 1 and the movable ring 3, the operator rotates the movable ring 3 to close the connection between the movable ring 3 and the connecting rod 1. Then, the operator pushes the push block 9 to extend the first wedge block 8 on the first sliding plate 7 through the through groove 10 and insert it into the locking groove 11 opened in the movable ring 3. The second wedge block 16 at the front end of the second sliding plate 14 has an inclined surface that matches the first wedge block 8. Therefore, when the first wedge block 8 is inserted into the locking groove 11, the second wedge block 16 will move aside. Then, when the first wedge block 8 is fully inserted into the locking groove 11, the second wedge block 16 will rebound under the action of the second spring 15, thereby restricting the first wedge block 8 and locking the movable ring 3.

[0027] Example 2: Please refer to Figures 1-6 for a quick-release and anti-loosening connecting rod bushing structure. The top of the locking groove 11 is rotatably engaged with a connecting rod 17, and the bottom end of the connecting rod 17 extends into the locking groove 11 and is fixedly connected to an eccentric wheel 18. The top end of the connecting rod 17 extends to the outside of the locking groove 11 and is fixedly connected to an adjustment knob 19. The outer peripheral surface of the adjustment knob 19 is provided with anti-slip protrusions.

[0028] Specifically, adjusting knob 19 can better adjust the rotation of eccentric wheel 18, so that eccentric wheel 18 can press the second sliding plate 14, thereby restricting or releasing the restriction of the first wedge block 8 by the second wedge block 16, thus maintaining a stable connection between the moving ring 3 and the connecting rod 1. The anti-slip protrusions on the surface of adjusting knob 19 can better prevent the operator from slipping when rotating.

[0029] In this embodiment: the adjusting knob 19 is provided with a locking hole 20; The sidewalls of the locking groove 11 and the locking hole 20 are provided with internal threads and are threadedly connected with a positioning bolt 21. When the adjusting knob 19 is rotated to the predetermined position, the positioning bolt 21 can be screwed into and pass through the locking hole 20.

[0030] Specifically, because the inner walls of the locking groove 11 and the locking hole 20 are threaded, it is easy to install the positioning bolt 21 into them, thereby fixing the adjusting knob 19 with the positioning bolt 21, thereby providing secondary restriction to the movable ring 3 and improving its reliability.

[0031] Working principle: Adjusting knob 19 can effectively adjust the rotation of eccentric wheel 18, thereby causing eccentric wheel 18 to press against second sliding plate 14. This causes second wedge block 16 to restrict or release the restriction on first wedge block 8, thus maintaining a stable connection between moving ring 3 and connecting rod 1. The anti-slip protrusions on the surface of adjusting knob 19 can effectively prevent slippage during rotation. The inner walls of locking groove 11 and locking hole 20 are threaded, which facilitates the installation of positioning bolt 21, thereby fixing adjusting knob 19 and providing secondary restriction on moving ring 3 to improve its reliability.

[0032] Example 3: Please refer to Figures 1-6 for a quick-release and anti-loosening bushing structure for a connecting rod 1. Two locking washers 22 are fitted on the screw of the positioning bolt 21. The two locking washers 22 are located between the adjusting knob 19 and the outer wall of the locking groove 11. The bottom surface of the upper locking pad 22 is provided with a plurality of first locking teeth 23 arranged in a circumferential array; The top surface of the locking pad 22 located below is provided with a plurality of second locking teeth 24 arranged in a circumferential array; The first locking tooth 23 and the second locking tooth 24 engage with each other.

[0033] Specifically, a locking washer 22 is provided between the positioning bolt 21 and the locking groove 11, and the second locking teeth 24 installed on the two locking washers 22 mesh with each other. Therefore, when vibration occurs, the two second locking teeth 24 on the locking washer 22 will squeeze each other to mesh. Then, the first locking teeth 23 on the locking washer 22 contact the outer wall of the bottom locking groove 11 of the positioning bolt 21. Therefore, when vibration occurs, they can make good contact with it. At the same time, when vibration occurs, they mesh with each other to prevent the positioning bolt 21 from falling off. Therefore, it can be used without loosening under vibration. At the same time, it is also simple for the operator to operate, just set it at the bottom of the positioning bolt 21.

[0034] Working principle: The two second locking teeth 24 on the locking washer 22 will squeeze each other to form a mesh, and the first locking teeth 23 on the locking washer 22 will contact the outer wall of the bottom locking groove 11 of the positioning bolt 21. Therefore, when there is vibration, it can make good contact with it. At the same time, when there is vibration, the meshing can effectively prevent the positioning bolt 21 from falling off. Therefore, it can be effectively prevented from loosening when used under vibration.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
