Description

Technical Field

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

[0002] Rubber shock-absorbing pads are characterized by both high elasticity and high viscosity. The elasticity of rubber is generated by the change in the conformation of its coiled molecules. The interaction between rubber molecules hinders the movement of molecular chains, thus exhibiting the characteristics of viscous damping. As a result, stress and strain are often in an unbalanced state. Rubber shock-absorbing pads are widely used, and shock-absorbing pads are used in existing household appliances to play a role in shock absorption and buffering protection. However, existing shock-absorbing pads often have certain shortcomings in specific applications, so they need to be improved.

[0003] Chinese patent CN217873930U discloses a rubber shock-absorbing pad that solves the problems of aging and displacement of rubber shock-absorbing pads on the market when subjected to impacts such as collisions. The pad includes a threaded opening with a rubber pad fixedly connected to the bottom. The surface of the rubber pad has through holes, and a buffer mechanism is provided inside the threaded opening. The buffer mechanism includes a connecting hole, a snap-fit ​​plate, and a pressure rod. Rubber protective wax forms a protective film on the surface of the rubber pad, isolating it from the corrosive effects of oxygen and ozone in the air, thus preventing aging. A pull ring allows for portable connection of the rubber pad to machinery. An anti-slip pad on the outer side of the rubber pad prevents displacement, and the pad does not shift significantly under large external forces, improving its stability.

[0004] However, while the above-mentioned technical solution can achieve the purpose of buffering and guiding the rubber pad to avoid displacement, when the shock-absorbing pad is subjected to a large force, the buffer spring will buffer the impact. Since the snap-fit ​​plate is fixed inside the connecting hole, and the connecting hole is opened inside the rubber pad, the snap-fit ​​plate will cause the rubber pad to shift when it moves downward. There are two snap-fit ​​plates, and when they descend, they will cause other parts of the top of the rubber pad to descend as well. Over time, this will cause the rubber pad to wrinkle or even crack, resulting in damage and affecting subsequent use. Therefore, it has certain limitations in use. Utility Model Content

[0005] The purpose of this invention is to provide a rubber shock-absorbing pad for household appliances to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rubber shock-absorbing pad for household appliances includes: a stable base, a rubber pad disposed on the top of the stable base, a pressure plate connected to the bottom of the rubber pad, a guide cavity opened inside the stable base, a first buffer cavity disposed inside the stable base, a second buffer cavity fixedly connected inside the stable base, a first positioning rod fixedly connected to both sides of the bottom wall of the second buffer cavity, a first compression rod slidably connected through the inside of the first positioning rod, a first damping block disposed on the inner bottom wall of the first positioning rod, a first buffer spring fixedly connected to the top of the first damping block, and the top end of the first buffer spring fixedly connected to the bottom end of the first compression rod, two second positioning rods fixedly connected to the inner bottom wall of the first buffer cavity, a second damping block disposed on the inner bottom wall of the second positioning rod, a second buffer spring fixedly connected to the top of the second damping block, a second compression rod slidably connected through the inside of the second positioning rod, and the top end of the second buffer spring fixedly connected to the bottom end of the second compression rod.

[0015] (2) The rubber pad and the lower pressure plate can play a certain guiding role when descending, preventing the rubber pad from shifting and ensuring its stability during movement. At the same time, the three anti-slip pads can ensure the stability of the connection between the rubber pad and the lower pressure plate, the stability of the connection between the base and the ground, and the stability of the rubber pad after it is connected to the home appliance. In addition, the rubber pad is easy to replace after it is worn, which is convenient. Attached Figure Description

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.

[0022] Example 1:

[0023] Please see Figures 1 to 4As shown, a rubber shock-absorbing pad for household appliances includes a stable base 1, a rubber pad 2 disposed on the top of the stable base 1, a lower pressure plate 3 connected to the bottom of the rubber pad 2, a guide cavity 4 opened inside the stable base 1, a first buffer cavity 5 disposed inside the stable base 1, a second buffer cavity 6 fixedly connected inside the stable base 1, a first positioning rod 7 fixedly connected to both sides of the bottom wall of the second buffer cavity 6, a first compression rod 8 passing through and slidably connected inside the first positioning rod 7, a first damping block 9 disposed on the inner bottom wall of the first positioning rod 7, a first buffer spring 10 fixedly connected to the top of the first damping block 9, and the top end of the first buffer spring 10 fixedly connected to the bottom end of the first compression rod 8, two second positioning rods 11 fixedly connected to the inner bottom wall of the first buffer cavity 5, a second damping block 12 disposed on the inner bottom wall of the second positioning rod 11, a second buffer spring 13 fixedly connected to the top of the second damping block 12, a second compression rod 14 passing through and slidably connected inside the second positioning rod 11, and the top end of the second buffer spring 13 fixedly connected to the bottom end of the second compression rod 14. The rubber pad 2 provides cushioning and shock absorption during appliance use. The pressure plate 3 compresses the first compression rod 8 when the rubber pad 2 is compressed. The first positioning rod 7 houses the first damping block 9. The first buffer spring 10 provides cushioning when the first compression rod 8 is compressed. The first damping block 9 slows down the descent of the first buffer spring 10, improving its cushioning effect. The top of the first compression rod 8 is fixedly connected to the bottom of the pressure plate 3. The second positioning rod 11 houses the second damping block 12. The combination of the second compression rod 14, the second buffer spring 13, and the second damping block 12 provides secondary cushioning when the second compression rod 14 is compressed. The second compression rod 14 is positioned lower than the first compression rod 8 to ensure that the first compression rod 8 compresses the first buffer spring 10 to a certain extent before compressing the second compression rod 14.

[0024] Example 2:

[0025] Please see Figures 1 to 3 As shown, strip plates 15 are fixedly connected to all four sides of the bottom of the lower pressure plate 3. A lower pressure rod 16 is fixedly connected to one side of the bottom of the strip plate 15. A guide ring 17 is fixedly connected to the bottom end of the lower pressure rod 16, and the guide ring 17 is slidably connected inside the guide cavity 4. The strip plates 15 fix the lower pressure rod 16, and the lower pressure rod 16 fixes the guide ring 17, which moves downward with the lower pressure plate 3. The guide cavity 4 and the guide ring 17 provide a guiding function when the lower pressure plate 3 descends, maintaining its stability.

[0026] A first anti-slip pad 18 is provided on the top of the rubber pad 2, and a second anti-slip pad 19 is provided on the top of the lower pressure plate 3, with the top of the second anti-slip pad 19 contacting the bottom of the rubber pad 2. The first anti-slip pad 18 ensures the stability of the rubber pad 2 after it is installed in the corresponding position on the appliance. The second anti-slip pad 19 improves the stability of the rubber pad 2 connected to the lower pressure plate 3. It should be noted that both the first anti-slip pad 18 and the second anti-slip pad 19 are connected to the rubber pad 2 and the lower pressure plate 3 by an adhesive layer, facilitating subsequent disassembly and replacement.

[0027] The bottom of the stable base 1 is provided with a third anti-slip pad 20, and four handles 21 are fixedly connected to the surface of the stable base 1. The third anti-slip pad 20 makes the stable base 1 more stable when in contact with the ground, preventing displacement. The third anti-slip pad 20 is also connected to the bottom of the stable base 1 by an adhesive layer, which facilitates subsequent disassembly. The handles 21 make it easy for workers to lift the stable base 1 to a certain height, which facilitates the subsequent installation of the rubber pad 2.

[0028] A circular hole is provided in the center of the top of the lower pressure plate 3. A positioning sleeve 22 is fixedly connected inside the circular hole. A connecting rod is fixedly connected in the center of the bottom of the rubber pad 2, and the surface of the connecting rod is threaded into the inside of the positioning sleeve 22. The circular hole allows the positioning sleeve 22 to be installed inside it. The connecting rod is screwed into the positioning sleeve 22, which facilitates the subsequent separation of the lower pressure plate 3 from the rubber pad 2 and makes it convenient for workers to replace the second anti-slip pad 19.

[0029] A mounting block 23 is fixedly connected to the top of the rubber pad 2 around its surface, and a screw is threaded into the mounting block 23. The mounting block 23 and the screw ensure a stable connection between the rubber pad 2 and the appliance, while also facilitating subsequent disassembly.

[0030] The working principle of this utility model is as follows: The operator first uses handle 21 to press the mounting block 23 on the rubber pad 2 against the bottom of the appliance, then screws it in, fixing the rubber pad 2 to the appliance. When the rubber pad 2 is subjected to pressure, the lower pressure plate 3 presses the first pressure rod 8, causing it to descend and compress the first buffer spring 10, thus providing initial cushioning for the rubber pad 2. If the pressure is too high, the lower pressure plate 3 continues to move downwards, compressing the second pressure rod 14, which in turn compresses the second buffer spring 13, providing further cushioning. Simultaneously, the lower pressure plate 3 lowers the strip plates 15 around its bottom perimeter, which in turn lower the lower pressure rod 16. The lower pressure rod 16 then moves the guide ring 17 downwards within the guide cavity 4, providing guidance for the lower pressure plate 3 and the rubber pad 2 during descent, preventing deviation and protecting the rubber pad 2 from tearing and deformation.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
