Description

Technical Field

[0001] The utility model relates to the field of rubber shock absorbers, and particularly relates to a rubber shock absorber with a limiting structure. Background Art

[0002] A rubber shock absorber, also known as a rubber vibration damper, is an important type of shock-absorbing component, usually made of rubber material. Its working principle is to absorb and disperse impact energy through the elasticity of the rubber, thereby achieving the effect of shock absorption. Due to its unique performance, rubber shock absorbers have been widely used in various fields such as machinery, automobiles, railway locomotives, water transportation tools, airplanes and other aircraft.

[0003] After retrieval, a patent for invention with the publication number of CN104608783B specifically discloses a rubber shock absorber, which includes a top plate and a vulcanized rubber body. The top plate is embedded in the top of the vulcanized rubber body. A trapezoidal positioning groove is provided at the center of the lower end of the vulcanized rubber body. Trapezoidal positioning structures are symmetrically provided on both sides of the positioning groove, and fixed convex platforms are provided on both sides of the inner wall of the trapezoidal positioning groove. Force-bearing workbenches are provided on both sides of the lower end of the vulcanized rubber body, and the upper part of the force-bearing workbench is transitioned with the top surface of the vulcanized rubber body at a certain angle. This shock absorber reduces the number of shock absorbers used, is simple to install, saves man-hours, improves the installation efficiency, and reduces the cost.

[0004] When the existing rubber shock absorber is shock-absorbing, the rubber body needs to be continuously squeezed. Moreover, there is no effective limiting structure inside the existing rubber shock absorber, and it cannot ensure that the force can be evenly distributed on the rubber body during each extrusion. As a result, when the rubber body is under uneven stress for a long time, it will be damaged, thus shortening its service life.

[0005] Therefore, it is very necessary to invent a rubber shock absorber with a limiting structure to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a rubber shock absorber with a limiting structure. Through the cooperation of the limiting block and the limiting hole, the rubber shock-absorbing sleeve is limited up and down, so that it can be effectively limited during static or shock-absorbing processes, in order to solve the problems of uneven stress and shortened service life of the rubber shock-absorbing sleeve in the prior art.

[0007] In order to achieve the above purpose, the utility model provides the following technical solution: A rubber shock absorber with a limiting structure includes a rubber shock-absorbing sleeve, and a plurality of groups of limiting holes are annularly distributed on the upper and lower sides of the rubber shock-absorbing sleeve;

[0008] A limiting component is arranged on the upper and lower sides of the rubber shock-absorbing sleeve for limiting the rubber shock-absorbing sleeve;

[0009] The fixing component is arranged above the limiting component and is used to fixedly connect the limiting component and the rubber shock absorber sleeve.

[0010] Preferably, the limiting component includes a first connecting cylinder, the first connecting cylinder is connected through above the rubber shock absorber sleeve, and an annular cavity is formed on the inner wall of the first connecting cylinder.

[0011] Preferably, a second connecting cylinder is connected through below the rubber shock absorber sleeve, a limiting ring is fixedly sleeved above the second connecting cylinder, and the limiting ring is slidably connected with the annular cavity.

[0012] Preferably, a connecting ring is installed below the second connecting cylinder, a plurality of limiting blocks are annularly distributed and installed above the connecting ring, and the limiting blocks are clamped with the corresponding limiting holes below the rubber shock absorber sleeve.

[0013] Preferably, the fixing component includes a fixing ring, the fixing ring is sleeved on the first connecting cylinder, a plurality of limiting blocks are also installed below the fixing ring, and the limiting blocks are clamped with the limiting holes above the rubber shock absorber sleeve. A guiding block is installed on the inner wall of the fixing ring.

[0014] Preferably, a guiding groove is formed on the outer side of the first connecting cylinder, and the guiding groove is slidably connected with the corresponding guiding block. A bolt is connected through the guiding block, and a threaded hole is formed below the inner wall of the guiding groove, and the threaded hole is screwed with the bolt.

[0015] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0016] Through the cooperation of the limiting holes and the limiting blocks, the rubber shock absorber sleeve is limited. And because the upper limiting block is limited by the bolt, the situation that the rubber shock absorber sleeve disengages and rotates is avoided, so as to further limit the rubber shock absorber sleeve. During the shock absorption process, the first connecting cylinder will contract into the second connecting cylinder, so that the pressure is evenly dispersed on the surface of the rubber shock absorber sleeve, avoiding the occurrence of uneven stress. Through this structure, the rubber shock absorber sleeve can be effectively limited in the static state or the shock absorption state, thereby improving the service life of the rubber shock absorber sleeve.

[0027] A fixing component 003, which is arranged above the limit component 002 and is used to fixedly connect the limit component 002 and the rubber shock-absorbing sleeve 001.

[0028] Further, in the above structure, the limit component 002 includes a connecting cylinder 1 (201), the connecting cylinder 1 (201) is connected through the upper part of the rubber shock-absorbing sleeve 001, and an annular cavity 202 is formed on the inner wall of the connecting cylinder 1 (201).

[0029] Further, in the above structure, a connecting cylinder 2 (206) is connected through the lower part inside the rubber shock-absorbing sleeve 001, a limit ring 203 is sleeved and fixed above the outer side of the connecting cylinder 2 (206), and the limit ring 203 is slidably connected with the annular cavity 202.

[0030] Through the cooperation of the limit ring 203 and the annular cavity 202, the positions of the connecting cylinder 1 (201) and the connecting cylinder 2 (206) are limited, and when the rubber shock-absorbing sleeve 001 is squeezed, the connecting cylinder 1 (201) will slide inside the connecting cylinder 2 (206).

[0031] Further, in the above structure, a connection ring 204 is installed below the second connection cylinder 206. A plurality of limiting blocks 205 are annularly distributed and installed above the connection ring 204, and the limiting blocks 205 are clamped with the corresponding limiting holes 101 below the rubber shock absorber sleeve 001.

[0032] Through the cooperation of the limiting holes 101 and the limiting blocks 205, the position of the rubber shock absorber sleeve 001 relative to the second connection cylinder 206 is limited.

[0033] Further, in the above structure, the fixing component 003 includes a fixing ring 301. The fixing ring 301 is sleeved on the first connection cylinder 201, and a plurality of limiting blocks 205 are also installed below the fixing ring 301. The limiting blocks 205 are clamped with the limiting holes 101 above the rubber shock absorber sleeve 001. A guiding block 302 is installed on the inner wall of the fixing ring 301.

[0034] Through the limiting blocks 205 below the fixing ring 301, the fixing ring 301 can further limit the rubber shock absorber sleeve 001.

[0037] The working principle of this utility model:

[0038] Refer to the attached instruction manual Figures 1-4, by sleeving the first connecting cylinder 201 and the second connecting cylinder 206 below the rubber shock-absorbing sleeve 001, and clamping the limiting hole 101 below the rubber shock-absorbing sleeve 001 with the limiting block 205 above the connecting ring 204, and sleeving the fixing ring 301 on the first connecting cylinder 201, and at the same time, pulling and clamping the limiting block 205 below the fixing ring 301 with the limiting hole 101 above the rubber shock-absorbing sleeve 001, and at the same time, the guiding block 302 is slidably connected with the guiding groove 303. At this time, the bolt 304 passes through the guiding block 302 and is screwed with the threaded hole 305, thus completing the limiting assembly. At this time, the whole is installed in cooperation with the equipment. When the installation position vibrates, at this time, the first connecting cylinder 201 will contract into the second connecting cylinder 206, thereby squeezing the rubber shock-absorbing sleeve 001. Due to the cooperation of the limiting hole 101 and the limiting block 205, the force on the rubber shock-absorbing sleeve 001 is made uniform, avoiding the occurrence of uneven force. And the limiting block 205 below the fixing ring 301 is limited by the guiding groove 303 and the bolt 304, thus avoiding the loosening of the rubber shock-absorbing sleeve 001 in the static state and further limiting it. This kind of structure can effectively avoid the uneven force on the rubber shock-absorbing sleeve 001 and the situation of reducing its service life.

[0039] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
