Description

Technical Field

[0001] This utility model belongs to the field of rubber product technology, specifically relating to a shock-absorbing rubber product. Background Technology

[0002] Rubber vibration damping products, also known as rubber shock absorbers or vibration isolation products, are shock-absorbing and buffering products made primarily of rubber to eliminate or reduce the transmission of mechanical vibrations. They can reduce impact damage and achieve noise reduction. These products are suitable for low-frequency vibration isolation and buffering, primarily used as shock absorbers in vehicle and marine equipment. They are widely used in building construction, machinery, vehicles, ships, and instruments. These products include rubber shock absorbers, rubber bumpers (blocks, pads), rubber connectors, air springs, and rubber guards, typically employing pure rubber or a structure reinforced with fabric or metal skeleton. Manufacturing processes include compression molding vulcanization, transfer molding vulcanization, and injection molding vulcanization.

[0003] While existing rubber products can achieve shock absorption, most rubbers have a high natural frequency and are easily affected by external environmental factors (such as changes in temperature and humidity), leading to performance fluctuations. Furthermore, they are difficult to withstand excessive loads, and prolonged heavy loads may cause loosening or permanent deformation. Therefore, we propose a shock-absorbing rubber product. Utility Model Content

[0004] The purpose of this invention is to provide a shock-absorbing rubber product to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shock-absorbing rubber product, comprising a second support plate, a base disposed below the second support plate, a groove laterally formed on the surface of the base, a fixed shaft fixedly mounted laterally on the inner side of the groove, sliders symmetrically slidably mounted at both ends of the surface of the fixed shaft, a connecting rod rotatably connected above the sliders, a connecting block rotatably mounted at the top end of the connecting rod, the connecting block being fixedly connected to the bottom surface of the second support plate, a first spring sleeved on the surface of the fixed shaft, the first spring being disposed between the sliders, and both ends being fixedly connected to the inner surface of the sliders, a rubber sleeve filling the space between the inner side of the first spring and the surface of the fixed shaft.

[0006] Preferably, multiple sets of uprights are respectively installed on the surface of the base. A buffer cavity is formed on the inner side of each upright. A sliding hole is formed on the top surface of each upright. A support rod is slidably inserted through the inner side of the sliding hole. The top of the support rod is fixedly connected to the bottom surface of the second support plate. A pressure block is fixedly installed at the bottom of the support rod. A second spring is vertically installed inside the buffer cavity. The bottom of the pressure block is fixedly connected to the top of the second spring. A rubber column is filled inside the second spring.

[0007] Preferably, rubber blocks are fixedly connected to both sides of the second support plate and the base, and the rubber blocks are arranged symmetrically.

[0008] Preferably, multiple sets of rubber sheets are uniformly installed on the surface of the second support plate, and the top of the rubber sheets is fixedly connected to the first support plate. Multiple sets of buffer holes are formed between the rubber sheets, the first support plate, and the second support plate.

[0009] Preferably, mounting blocks are symmetrically fixedly connected to both sides of the second support plate, and positioning holes are provided on the surface of the mounting blocks.

[0010] Preferably, the rubber block is installed in an arc shape between the first support plate and the second support plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. When the first support plate and the second support plate move downward, they will simultaneously drive the support rod to move downward, the slider will move relative to the surface of the fixed shaft, and the rubber block will be squeezed. The first spring, rubber sleeve and second spring, rubber column can absorb the force generated, thereby achieving the effect of shock absorption.

[0013] 2. When an external force is applied to the first support plate, the buffer holes can disperse the stress and reduce local deformation. At the same time, the first support plate is allowed to undergo small displacement or deformation when under pressure, thereby consuming some energy. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a shock-absorbing rubber product, including a second support plate 4, a base 5 below the second support plate 4, a horizontal groove 7 on the surface of the base 5, a fixed shaft 8 fixedly installed on the inner side of the groove 7, sliders 9 symmetrically slidably installed at both ends of the surface of the fixed shaft 8, a connecting rod 10 rotatably connected above the sliders 9, a connecting block 11 rotatably installed at the top of the connecting rod 10, the connecting block 11 being fixedly connected to the bottom surface of the second support plate 4, a first spring 13 sleeved on the surface of the fixed shaft 8, the first spring 13 being located between the sliders 9, and both ends being fixedly connected to the inner surface of the sliders 9, a rubber sleeve 12 filling the space between the inner side of the first spring 13 and the surface of the fixed shaft 8.

[0022] Specifically, multiple sets of uprights 14 are installed on the surface of the base 5. A buffer cavity 16 is opened on the inner side of the upright 14. A sliding hole 19 is opened on the top surface of the upright 14. A support rod 15 is slidably inserted through the inner side of the sliding hole 19. The top of the support rod 15 is fixedly connected to the bottom surface of the second support plate 4. A pressure block 20 is fixedly installed at the bottom end of the support rod 15. A second spring 18 is vertically installed inside the buffer cavity 16. The bottom of the pressure block 20 is fixedly connected to the top of the second spring 18. A rubber column 17 is filled inside the second spring 18.

[0023] Specifically, rubber blocks 6 are fixedly connected on both sides between the second support plate 4 and the base 5, and the rubber blocks 6 are arranged symmetrically.

[0024] Specifically, multiple sets of rubber sheets 2 are evenly installed on the surface of the second support plate 4. The top of the rubber sheet 2 is fixedly connected to the first support plate 1, and multiple sets of buffer holes 3 are formed between the rubber sheet 2, the first support plate 1, and the second support plate 4.

[0025] Specifically, mounting blocks 21 are symmetrically fixedly connected to both sides of the second support plate 4, and positioning holes 22 are provided on the surface of the mounting blocks 21.

[0026] Specifically, the rubber block 6 is installed in an arc shape between the first support plate 1 and the second support plate 4.

[0027] In this embodiment, the rubber sheet 2 and the buffer hole 3 can change the stress transmission path on the surface of the first support plate 1, reducing local stress concentration. When an external force is applied to the first support plate 1, the buffer hole 3 can disperse the stress, reduce local deformation, and at the same time allow the first support plate 1 to produce small displacements or deformations when under pressure, thereby consuming some energy. First: When the first support plate 1 and the second support plate 4 move downwards, the support rod 15 can drive the slider 9 to move relative to the surface of the fixed shaft 8. The first spring 13 and the rubber sleeve 12 can absorb the force generated. Second: When the first support plate 1 and the second support plate 4 move downwards, the support rod 15 will move downwards into the interior of the upright 14. The pressure block 20 can compress the second spring 18 and the rubber column 17 inside the buffer cavity 16, thereby absorbing the force generated. Third: When the first support plate 1 and the second support plate 4 move downwards, the rubber block 6 will be squeezed. The restoring elasticity of the rubber block 6 will dampen the vibration between the second support plate 4 and the base 5. The mounting block 21 and the positioning hole 22 facilitate the installation and fixation of the device.
