Description

Technical Field

[0001] The utility model relates to the technical field of rubber shock absorbers, in particular to a wear-resistant and flexible rubber shock absorber. Background Art

[0002] As an important type of shock absorbing component, rubber shock absorbers have been widely used in various types of machinery, automobiles, railway locomotives, water transportation vehicles, airplanes and other aircraft. It can be said that rubber shock absorbers are needed wherever shock absorption and seismic isolation are needed.

[0003] The Chinese patent with publication number CN220118569U discloses a rubber shock absorber for automobile, which includes a mounting frame, the inner wall of which is movably connected with a fixing mechanism, and the inner wall of which is clamped with a mounting block, thereby solving the problem that the existing rubber shock absorbers for automobiles mostly use rubber as a support only during use, and are prone to deformation after long-term use, which affects the use effect. Secondly, most ordinary rubber shock absorbers in the prior art are fixed structures, which are inconvenient to disassemble. Although the above-mentioned utility model can be quickly disassembled and replaced, it is easy to have unstable fixation by using a spring to drive a spring pin for fixing. When the rubber shock absorber is in vibration, the spring will also drive the spring pin to vibrate.

[0004] With respect to the above-mentioned related technologies, the rubber shock absorber has some shortcomings. In actual use, the shock absorber body is exposed to the air and is easily affected by the external environment, such as moisture, chemicals, etc., resulting in corrosion and wear. This exposed design makes the shock absorber insufficiently protective, making it difficult to effectively prevent it from being affected by corrosion and wear, and reducing its service life. Therefore, it is necessary to provide a wear-resistant and flexible rubber shock absorber to solve the above technical problems. Utility Model Content

[0005] The utility model aims to provide a wear-resistant and flexible rubber shock absorber to solve the problems raised in the above-mentioned background technology.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model uses a mounting frame, a rubber shock absorber body, an annular elastic rubber pad, a mounting plate, a protective cover, a mounting groove, a positioning plate, a connecting rod, a fixing groove, an adjusting block, a connecting groove, an adjusting screw rod, a mounting cavity, an arc-shaped slot and a card slot in coordination. During use of the rubber shock absorber body, the rubber shock absorber body is protected by the protective cover, thereby avoiding the rubber shock absorber body from being directly exposed to the air for use, reducing the influence of the external environment on it, and prolonging the service life of the rubber shock absorber body.

[0033] A positioning plate 7 is fixedly installed on the top of the two connecting rods 8, and the positioning plate 7 is located inside the fixing groove 9 and is slidably connected to the fixing groove 9. The positioning plate 7 is clamped with the arc-shaped slot 14 and the card slot 19. A groove 18 is opened on one side of the mounting frame 1, and one end of the adjusting screw rod 12 extends to the inside of the groove 18, and a rotating plate 17 is fixedly installed on one end of the adjusting screw rod 12.

[0034] A plug hole 22 is provided above one side of the rotating plate 17, and an extension groove 25 is provided on the inner wall of the plug hole 22. The rotating plate 17 is slidably connected with a plug rod 23 through the plug hole 22. An annular baffle 15 is fixedly installed on the outer wall of the plug rod 23, and the annular baffle 15 is slidably connected to the extension groove 25.

[0036] In one of the preferred embodiments, the outer diameter of the protective cover 5 is adapted to the inner diameter of the mounting groove 6, and the inner diameter of the protective cover 5 is adapted to the outer diameter of the mounting plate 4, so that the installation between the protective cover 5, the mounting plate 4 and the mounting groove 6 is more consistent, thereby improving the stability after installation.

[0037] In one embodiment, a threaded hole matched with the adjusting screw rod 12 is opened on one side of the adjusting block 10, and the adjusting block 10 is threadedly connected to the adjusting screw rod 12 through the threaded hole opened on one side.

[0038] In one preferred embodiment, the rubber shock absorber body 2 is formed by combining multiple layers of rubber to increase the flexibility and energy absorption capacity of the shock absorber.

[0039] The working principle of the utility model is as follows: the parts not involved in the device are the same as the prior art or can be implemented by the prior art. During the use of the rubber shock absorber body 2, the rubber shock absorber body 2 is first assembled with the mounting frame 1, and the protective cover 5 is directly clamped on the outer wall of the mounting plate 4, so that the rubber shock absorber body 2 is located in a relatively closed space formed by the protective cover 5 and the mounting plate 4 for use. After the protective cover 5 is clamped on the outer wall of the mounting plate 4, the protective cover 5 is rotated to align the arc-shaped slot 14 on the protective cover 5 with the clamping slot 19 on the mounting plate 4, and then the mounting plate 4 together with the protective cover 5 is placed inside the mounting groove 6, and the arc-shaped slot 14 is aligned with the position of the fixed groove 9 on the inner wall of the mounting groove 6, and the rotating plate 17 is rotated at the same time. The rotation of the rotating plate 17 drives the adjusting screw rod 12 to rotate, and the two adjusting blocks 10 are relatively moved or moved in the opposite direction through the thread transmission of the left-handed thread and the right-handed thread on the adjusting screw rod 12, and the sliding relationship between the adjusting block 10 and the mounting cavity 13. The movement of the adjusting block 10 is driven by the connecting rod 8 The positioning plate 7 moves, and at this time, the two positioning plates 7 are adjusted to move relative to each other, and are directly inserted into the arc-shaped slot 14 and the interior of the slot 19, and the positioning of the mounting plate 4 and the protective cover 5 is completed at the same time, so that the mounting plate 4 and the protective cover 5 are firmly clamped in the interior of the mounting slot 6, and the fixed assembly between the rubber shock absorber body 2 and the mounting frame 1 is completed. The rubber shock absorber body 2 can be used subsequently through the fixation of the mounting frame 1. During the use of the rubber shock absorber body 2, the rubber shock absorber body 2 is protected by the protective cover 5 to avoid direct exposure of the rubber shock absorber body 2 to the air for use, reducing the impact of the external environment on it, and improving the service life of the rubber shock absorber body 2. At the same time, for the fixing mechanism between the mounting frame 1 and the rubber shock absorber body 2, the traditional bolt fixing is abandoned. The fixing structure is simple to operate, and multiple structures can be fixed at the same time, which is convenient for the later inspection and maintenance of the rubber shock absorber body 2. In addition, the rubber shock absorber body 2 adopts a multi-layer rubber combination design, which greatly increases the flexibility and energy absorption capacity of the shock absorber.

[0040] In the process of fixing the rubber shock absorber body 2 and the mounting bracket 1, before rotating the rotating plate 17, it is necessary to first use the handle 24 to pull the plug rod 23 out of the corresponding positioning groove 16. When pulling the plug rod 23, the plug rod 23 will drive the annular baffle 15 to squeeze the spring 26. As the plug rod 23 is separated from the corresponding positioning groove 16, the rotating plate 17 will lose the card-connecting limit between the positioning groove 16 and the plug rod 23, and the rotating plate 17 can be freely rotated to complete the disassembly and assembly between the mounting bracket 1 and the rubber shock absorber body 2. The clamping effect of the rod 23 and the positioning groove 16 can lock the rotating plate 17 when the mounting frame 1 and the rubber shock absorber body 2 are fixedly assembled, so that the rotating plate 17 cannot rotate. The rotating plate 17 will limit the adjusting screw rod 12 to prevent the positioning plate 7 from shifting due to the rotation of the adjusting screw rod 12 itself during use of the rubber shock absorber body 2, thereby affecting the installation firmness of the rubber shock absorber body 2. The clamping effect of the positioning groove 16 and the insertion rod 23 further improves the fixing firmness between the rubber shock absorber body 2 and the mounting frame 1, and the safety is higher.

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
