Description

Technical Field

[0001] This utility model relates to the technical field of shock absorber assembly tools, specifically an axial limiting structure for assembling rubber shock absorbers. Background Technology

[0002] A rubber shock absorber is a damping element that utilizes the elasticity of rubber to absorb and disperse impact energy. It typically consists of inner and outer steel sleeves and an inner synthetic rubber core. The main function of a rubber shock absorber is to isolate and reduce vibration and noise, and it is suitable for various equipment and devices, such as machinery and instruments, automobiles, ships, railways, and buildings.

[0003] A patent search revealed a document titled "A Rubber Shock Absorber for Easy Installation" (publication number "CN223152620U"). This document describes a design where the rubber shock absorber body and the base plate are integrally connected, meaning the base plate and shock absorber body cannot be disassembled. This prevents the base plate from being compatible with rubber shock absorbers of different diameters. Furthermore, the aforementioned device requires pulling four levers to separate the connecting block from the shock absorber body. Since these levers must be pulled simultaneously, multiple workers are needed to operate them concurrently to separate the connecting block from the shock absorber body. This method is time-consuming and labor-intensive, increasing the workload and difficulty for workers. Therefore, this invention designs an axial limiting structure for assembling a rubber shock absorber to solve the above problems. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model firstly ensures the stability of the rubber shock absorber and base plate combination by designing a positioning function so that the axis of the rubber shock absorber and the center of the base plate are in a coincident and limited state when the rubber shock absorber is combined with the base plate. In addition, the adjustment function allows the base plate to be matched with rubber shock absorbers of different diameters, improving the performance of the device.

[0017] 2. Through the mechanical linkage design, the present invention allows workers to separate the connecting plate from the rubber shock absorber simply by separating the second nut from the screw and then misaligning the clamping plate with the clamping slot so that the clamping plate coincides with the connecting hole. In addition, workers can separate the shock absorber body from the base plate simply by separating the first nut from the screw. This operation method saves time and effort and improves the convenience of disassembling and assembling the rubber shock absorber, connecting plate, and base plate. Attached Figure Description

Detailed Implementation

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] A preferred embodiment of the axial limiting structure for assembling the rubber vibration damper provided by this utility model is, for example... Figures 1 to 4As shown: An axial limiting structure for assembling a rubber shock absorber includes a base plate 1; a rubber shock absorber 2 disposed on the top of the base plate 1; connecting blocks 3 slidably disposed on the left and right sides inside the base plate 1; mounting blocks 4 fixed on the left and right sides of the lower end of the rubber shock absorber 2; an insertion hole 5 integrally disposed inside the mounting block 4, and the insertion hole 5 is a through hole; and a plug-in assembly 6 assembled on the outside of the base plate 1, which can disassemble and assemble the base plate 1 and the rubber shock absorber 2.

[0028] The plug-in assembly 6 includes a screw pin 601 fixed on the top of the connecting block 3; a first nut 602 sleeved on the outside of the screw pin 601; the screw pin 601 and the socket 5 are connected by plugging in, and the first nut 602 and the screw pin 601 are connected by thread.

[0029] It should be noted that the existing axial limiting structure for assembling rubber shock absorbers still has certain shortcomings in actual use. It cannot detach the base plate from the rubber shock absorber, resulting in the base plate being unable to be matched with rubber shock absorbers of different diameters.

[0030] In this embodiment, the worker first fits the screw pin 601 into the insertion hole 5 at the mounting block 4, and then combines the rubber shock absorber 2 with the base plate 1. At this time, the axis of the rubber shock absorber 2 and the center of the base plate 1 are in a state of overlap and limitation. The worker then connects the first nut 602 to the screw pin 601 by thread, thereby locking the state after the base plate 1 and the rubber shock absorber 2 are combined.

[0031] In a further preferred embodiment of this utility model, a drive assembly 7 is assembled inside the base plate 1. The drive assembly 7 controls the left and right connecting blocks 3 inside the base plate 1 to move in the lateral direction of the base plate 1. The drive assembly 7 includes a guide groove 701 integrally disposed inside the base plate 1, and the guide groove 701 is sleeved on the outside of the connecting block 3; a rotating rod 702 disposed inside the guide groove 701, and the rotating rod 702 rotatably passes through the base plate 1. The rotating rod 702 is threaded through the connecting block 3. The left connecting block 3 and the rotating rod 702 are designed to be connected by a left thread, and the right connecting block 3 and the rotating rod 702 are designed to be connected by a right thread.

[0032] In this embodiment, the operator rotates the rotating rod 702. Through the threaded transmission design between the rotating rod 702 and the connecting block 3, the connecting block 3 moves along the direction of the guide groove 701. That is, the connecting blocks 3 on the left and right sides drive the corresponding screw pins 601 to move in opposite directions or away from each other, so that the screw pins 601 on the left and right sides can be matched with rubber shock absorbers 2 of different diameters.

[0033] Example 2

[0034] Based on Example 1, a preferred embodiment of the axial limiting structure for assembling the rubber vibration damper provided by this utility model is as follows: Figures 1 to 4 As shown: The rubber shock absorber 2 has guide holes 8 integrally formed at the four corners of its top end. The guide holes 8 are blind holes. A spring 9 is fixed inside the guide holes 8, and a guide pin 10 is fixed to the top of the spring 9. The guide pin 10 is slidably connected to the guide holes 8. A support plate 11 is fixed to the middle of the rubber shock absorber 2. A connecting hole 12 is integrally formed in the middle of the support plate 11. A slot 13 is integrally formed in the middle of the support plate 11. The slot 13 is a blind slot, and it intersects the connecting hole 12 in a cross shape. A snap-fit ​​assembly is provided at the top of the guide pin 10. The snap-fit ​​assembly can be detached from the support plate 11. The snap-fit ​​assembly includes a connecting plate 14 set at the top of the guide pin 10; a screw 15 rotatably set in the middle of the connecting plate 14; and a snap-fit ​​plate 16 fixed at the bottom of the screw 15. A groove 17 is integrally formed on the middle side of the top end of the connecting plate 14. A second nut 18 is set inside the groove 17 and threaded onto the outside of the screw 15.

[0035] In this embodiment, after the base plate 1 and the rubber shock absorber 2 are combined, the operator inserts the screw 15 and the clamping plate 16 at the connecting plate 14 through the connecting hole 12, and the connecting plate 14 applies pressure to the guide pin 10. The guide pin 10 moves along the direction of the guide hole 8, and simultaneously, the spring 9 deforms. The operator then rotates the screw 15 by 90 degrees, thereby misaligning the clamping plate 16 with the connecting hole 12, and the clamping plate 16 overlaps with the clamping groove 13. The operator then releases the connecting plate 14, and through the rebound force of the spring 9, the guide pin 10 pushes the connecting plate 14 to move the clamping plate 16 upward along the direction of the guide hole 8, thereby clamping the clamping plate 16 into the clamping groove 13. The operator then threads the second nut 18 to the screw 15, and the second nut 18 is embedded in the groove 17. In this way, the connecting plate 14 and the rubber shock absorber 2 are combined.

[0036] In summary, this application, through its positioning function, ensures that the axis of the rubber shock absorber is aligned with the center of the base plate. The adjustment function allows the base plate to be used with rubber shock absorbers of different diameters, improving the device's performance. Furthermore, the mechanical linkage design not only separates the connecting plate from the rubber shock absorber but also separates the rubber shock absorber from the base plate, enhancing the ease of assembly and disassembly of the rubber shock absorber, connecting plate, and base plate.
