Description

Technical Field

[0001] The utility model belongs to the technical field of universal joint forks, and in particular relates to a shock-resistant universal joint fork and a component. Background Art

[0002] The universal joint in the prior art is a mechanical part for realizing variable-angle power transmission and is used in positions where the direction of the transmission axis needs to be changed. It is the "joint" component of the universal transmission device of the automobile drive system.

[0003] The Chinese patent with the publication number CN219692053U discloses a novel anti-seismic universal joint fork and assembly, including a universal joint fork and a connecting shaft, spring baffles are provided at both ends of the connecting shaft, two universal joint forks are provided on the connecting shaft, two guide rings for fixing the universal joint forks are provided on the connecting shaft, and the guide rings are connected to the universal joint fork through fixed pins, and a pressure spring A supporting the guide ring is provided on the connecting shaft, and the guide rings and the spring baffles are connected through pressure springs B. The above technical solution reduces the vibration and noise generated by the universal transmission device by arranging several groups of springs on the connecting shaft to absorb the vibration generated on each universal joint fork, and the central axis of the fork ear is parallel to the central axis of the universal joint fork, so as to reduce the collision generated when the universal joint transmission device shortens the spacing, and further reduce the vibration. However, in actual use, the spring will be frequently added to the use process, and the spring in the universal joint needs to be replaced after a period of use. It is not easy to disassemble the spring baffle, and subsequent maintenance is inconvenient;

[0004] The universal joint fork is also provided with a connecting end, and a transmission internal spline is provided in the connecting end. The transmission internal spline in the connecting end of the above technical solution is connected to the corresponding position. However, in actual use, when it is replaced or when the connection spacing is inconsistent, the length of the connecting end is fixed, which causes inconvenience and reduces the scope of application.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a shock-resistant universal joint fork and a component.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0008] A seismic-resistant universal joint fork and assembly, comprising a connecting shaft, a rotating ring on the connecting shaft is matched with two universal joint forks, a clamping groove is provided on one side of the connecting shaft, two fixing grooves are provided on the inner wall of the clamping groove, and a plug-in sheet is slidably matched on the inner wall of the clamping groove;

[0009] A convex groove is provided on one side of the connector, and two extrusion openings are provided on both sides of the inner wall of the convex groove. The inner walls of the two extrusion openings are slidably matched with fixed blocks that match the fixed groove, and the adjacent sides of the two fixed blocks are fixedly connected with a reset spring. The inner wall of the convex groove is elastically matched with a pull rod that matches the two fixed blocks, and one side of the pull rod is fixedly connected with an anti-slip plate that contacts the adjacent sides of the two fixed blocks. A pressure spring is provided on the connecting shaft and between the two universal joint forks and the connector.

[0010] Optionally, an operating ring is fixedly connected to one end of the pull rod, and a tension spring is fixedly connected between the operating ring and the convex groove. The tension spring pulls the operating ring, so that the anti-slip plate can be between the fixed blocks to block the two fixed blocks, thereby reducing the possibility of the fixed blocks escaping from the fixed groove.

[0011] Optionally, a connecting rope is fixedly connected between the two fixed blocks and the pull rod. When the pull rod moves to one side, the two fixed blocks can be pulled to move to the same side by the connecting rope, so as to achieve contraction between the two fixed blocks.

[0012] Optionally, the inner thread of the convex groove is connected with a sealing cover that abuts against the operating ring. The sealing cover is used to abut against the operating rod to prevent the possibility of displacement of the operating ring during use.

[0013] Optionally, one of the two fixed blocks is fixedly connected to a limiting rod, and the other side of the two fixed blocks is provided with a limiting groove that slidably cooperates with the limiting rod. When the two fixed blocks are pulled to move toward the adjacent side, the limiting rod slides in the limiting groove to guide the two fixed blocks.

[0014] Optionally, an anti-skid pad is fixedly connected to the outer side of the sealing cover, and the anti-skid pad is convenient for increasing the convenience of operating the sealing cover.

[0015] Optionally, two connecting plates are fixedly connected to the two connecting shafts, one side of the two connecting plates is provided with a telescopic groove, the inner wall of the telescopic groove is slidably matched with a connecting block, and one side of the connecting block is provided with a transmission internal spline. One side of the inner wall of the two telescopic grooves is rotatably matched with two threaded rods, and one side of the inner wall of the two telescopic grooves is rotatably matched with a worm that meshes with the two threaded rods. When the transmission position length is not enough, the corresponding threaded rod can be driven to rotate by rotating the worm, and the connecting block can be pushed by the threaded rod to leak out of the telescopic groove, so as to achieve the effect of adjusting its overall length, and then connected to the corresponding spline shaft through the transmission internal spline to achieve installation, and the length of its components can be adjusted according to the required transmission interval, thereby increasing the scope of application.

[0016] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0017] By setting the plug-in piece, it can be achieved that when in use, the fixing block in the plug-in piece is inserted into the fixing groove and fixed. The plug-in piece is used to limit the pressure spring. When the pressure spring needs to be removed, the plug-in piece can be directly removed by pulling the pull rod, thereby increasing the convenience of replacing the pressure spring. The connecting block can be adjusted out of the telescopic groove according to the required transmission spacing, and its different lengths can be adjusted. It can be suitable for transmission at spacings of different lengths, thereby increasing the scope of application of the device when installed.

[0029] The utility model will now be further described in detail with reference to the accompanying drawings.

[0030] See also Figure 1-6 As shown, in this embodiment, a seismic-resistant universal joint fork and assembly are provided, including a connecting shaft 1, a rotating ring on the connecting shaft 1 is matched with two universal joint forks 2, a clamping groove 3 is opened on one side of the connecting shaft 1, two fixing grooves 4 are opened on the inner wall of the clamping groove 3, and a plug-in piece 5 is slidably matched with the inner wall of the clamping groove 3;

[0031] A convex groove 6 is provided on one side of the connector 5, and two extrusion openings 7 are provided on both sides of the inner wall of the convex groove 6. The inner walls of the two extrusion openings 7 are slidably fitted with a fixed block 8 that matches the fixed groove 4, and the adjacent sides of the two fixed blocks 8 are fixedly connected with a return spring 9. The inner wall of the convex groove 6 is elastically fitted with a pull rod 10 that matches the two fixed blocks 8, and one side of the pull rod 10 is fixedly connected with an anti-slip plate 11 that contacts the adjacent sides of the two fixed blocks 8. A pressure spring 12 is provided on the connecting shaft 1 and between the two universal joint forks 2 and the connector 5.

[0032] The application of one aspect of this embodiment is as follows: when in use, the two universal joint forks 2 are connected to the positions requiring transmission at both ends through the corresponding connecting plates 20 for installation. After the installation is completed, the two universal joint forks 2 can be used to reduce noise and resist vibration and impact through the pressure springs 12. When the pressure springs 12 need to be replaced, the pull rod 10 can be pulled to one side to drive the anti-slip plate 11 to disengage from the two fixed blocks 8, and then the two fixed blocks 8 are pulled by the connecting rope 15 to make the two fixed blocks 8 shrink and disengage from the fixed groove 4, so that the plug-in plate 5 can be directly pulled out of the clamping groove 3, and the plug-in plate 5 releases the restriction on the pressure spring 12, thereby realizing the disassembly and replacement of the pressure spring 12, which increases the convenience of disassembly and replacement of the pressure spring 12.

[0033] By setting the plug-in sheet 5, it can be achieved that when in use, the fixing block 8 in the plug-in sheet 5 is inserted into the fixing groove 4 for fixing, and the plug-in sheet 5 is used to limit the pressure spring 12. When the pressure spring 12 needs to be removed, the plug-in sheet 5 can be directly pulled by pulling the pull rod 10 to remove it, thereby increasing the convenience of replacing the pressure spring 12. In addition, the connecting block 22 can be adjusted out of the telescopic groove 21 according to the required transmission spacing, so that different lengths can be adjusted, and it can be suitable for transmission at spacings of different lengths, thereby increasing the scope of application of the device when installed.

[0034] One end of the pull rod 10 of the present embodiment is fixedly connected with an operating ring 13, and a tension spring 14 is fixedly connected between the operating ring 13 and the convex groove 6. The tension spring 14 pulls the operating ring 13, so that the anti-slip plate 11 can be between the fixed blocks 8 to block the two fixed blocks 8, thereby reducing the possibility of the fixed block 8 detaching from the fixed groove 4.

When the pull rod 10 moves to one side, the two fixed blocks 8 can be pulled to move to the same side by the connecting rope 15, thereby achieving contraction between the two fixed blocks 8.

[0036] The inner thread of the convex groove 6 of the present embodiment is connected with a sealing cover 16 which abuts against the operating ring 13 . The sealing cover 16 can be used for the operating ring 13 as well.

[0037] One of the two fixed blocks 8 of the present embodiment is fixedly connected to a limiting rod 17, and the other side of the two fixed blocks 8 is provided with a limiting groove 18 that slidably cooperates with the limiting rod 17. When the two fixed blocks 8 are pulled to move to a closer side, the limiting rod 17 slides in the limiting groove 18 to guide the two fixed blocks 8.

[0038] In this embodiment, an anti-skid pad 19 is fixedly connected to the outer side of the sealing cover 16 , and the anti-skid pad 19 is convenient for increasing the convenience of operating the sealing cover 16 .

[0039] Two connecting plates 20 of this embodiment are fixedly connected to the two connecting shafts 1. One side of the two connecting plates 20 is provided with a telescopic groove 21. The inner wall of the telescopic groove 21 is slidably matched with a connecting block 22. One side of the connecting block 22 is provided with a transmission internal spline 23.

When the transmission position length is not enough, the worm 25 can be rotated to drive the corresponding threaded rod 24 to rotate, and the connecting block 22 is pushed by the threaded rod 24 to leak out of the telescopic groove 21, so as to achieve the effect of adjusting its overall length, and then connected with the corresponding spline shaft through the transmission internal spline 23 to achieve installation. The length of its components can be adjusted according to the required transmission interval, thereby increasing the scope of application.
