Description

Technical Field

[0001] This utility model relates to the technical field of washing machine shock absorbers, specifically a double-buffered washing machine shock absorber. Background Technology

[0002] During operation, washing machines, especially front-loading washing machines, generate significant vibrations. If these vibrations are not effectively dampened, they can cause excessive noise and shorten the lifespan of the washing machine. Therefore, shock absorbers are installed on the outside of the drum of front-loading washing machines. Most shock absorbers used in washing machines rely on damping oil for vibration reduction. Their shape and structure are mostly similar to the shock absorber disclosed in announcement number CN211772136U. Such shock absorbers are mostly single-buffered structures with fixed damping effects that cannot be adjusted. They are not compatible with different washing machine models, have poor applicability, and have certain shortcomings. Utility Model Content

[0003] The purpose of this invention is to provide a double-buffered washing machine shock absorber to solve the aforementioned technical problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a dual-buffered washing machine shock absorber, comprising a first shock absorber component, a second shock absorber component, and a connecting seat. The first and second shock absorber components have the same structure. The first shock absorber component includes a drum, a column, a spring, a connecting head, and a baffle. The column is slidably fitted into the drum, and damping oil is injected into the drum. The connecting head is fixedly connected to the top surface of the column, and a spring is fixedly connected to the connecting head. An external thread is provided on the outer wall of the drum, and a threaded baffle is fitted onto the external thread of the drum. Rotating the threaded baffle can change the trigger position of the spring, thereby adjusting the shock absorber's damping capacity. The bottom end of the drum of the first shock absorber component is fixedly connected to the top surface of the connecting seat, and a threaded through hole is provided on the connecting seat. The drum of the second shock absorber component is threadedly fitted into the threaded through hole.

[0005] Preferably, it also includes two threaded rings, which are threaded onto the outside of the cylinder of the second damping assembly. The connecting seat is located between the two threaded rings. By rotating the two threaded rings, the position of the connecting seat on the second damping assembly can be fixed.

[0006] Preferably, threaded connection holes are provided on the bottom surface of the connecting seat and the bottom end of the cylinder.

[0007] Preferably, a baffle is fixedly connected to the bottom end of the connector, and the top end of a spring is fixedly connected to the bottom surface of the baffle. The spring is sleeved on the outside of the cylinder and column.

[0008] Preferably, it also includes a connector without a baffle, wherein a threaded post adapted to the threaded connection hole is fixedly connected at the center of the bottom surface of the connector.

[0009] Preferably, the first and second damping components can be used independently.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention features a clever structure. In addition to the damping oil buffer, the device works with a spring to form a double buffer. By rotating the threaded baffle to adjust the spring trigger position, the device's shock absorption capacity and the trigger point of the double shock absorption can be flexibly changed. This can be adjusted according to needs to ensure optimal shock absorption. The threaded engagement between the second shock absorption component and the connecting seat, along with the fixing effect of the threaded ring, allows for adjustment of the overall length to adapt to different washing machine models. Furthermore, the first and second shock absorption components can be used in combination or independently, enriching the application scenarios, improving applicability and flexibility, and facilitating widespread adoption.

[0017] 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.

[0018] Please see Figures 1 to 4This utility model provides a technical solution: a double-buffered washing machine shock absorber, including a first shock absorber component 1, a second shock absorber component 2, and a connecting seat 3. The first shock absorber component 1 and the second shock absorber component 2 have the same structure. The first shock absorber component 1 includes a drum 11, a column 12, a spring 13, a connector 14, and a baffle 15. The column 12 is slidably sleeved inside the drum 11. Damping oil is injected into the drum 11. The connector 14 is fixedly connected to the top surface of the column 12. The spring 13 is fixedly connected to the connector 14. The outer wall of the drum 11 is provided with external threads. A threaded baffle 16 is sleeved on the external threads of the drum 11. Rotating the threaded baffle 16 can change the trigger position of the spring 13, thereby adjusting the shock absorber's damping capacity. The bottom end of the drum 11 of the first shock absorber component 1 is fixedly connected to the top surface of the connecting seat 3. A threaded through hole 3a is provided on the connecting seat 3. The drum 11 of the second shock absorber component 2 is threadedly sleeved in the threaded through hole 3a.

[0019] Furthermore, it also includes two threaded rings 4, which are threadedly fitted onto the outside of the cylinder 11 of the second shock absorber 2. The connecting seat 3 is located between the two threaded rings 4. By rotating the two threaded rings 4, the position of the connecting seat 3 on the second shock absorber 2 can be fixed. The two threaded rings 4 lock the cylinder 11 of the second shock absorber 2 to ensure its stability.

[0020] Furthermore, threaded connection holes 3b are provided on the bottom surface of the connecting seat 3 and the bottom end of the cylinder 11. The connecting head without the baffle 15 is also included. A threaded post that matches the threaded connection hole 3b is fixedly connected at the center of the bottom surface of the connecting head 14, which facilitates the independent use of the first shock absorber 1 and the second shock absorber 2.

[0021] Furthermore, a baffle 15 is fixedly connected to the bottom end of the connector 14, and the top end of the spring 13 is fixedly connected to the bottom surface of the baffle 15. The spring 13 is sleeved on the outside of the cylinder 11 and the column 12.

[0022] In use, both the first damping component 1 and the second damping component 2 can slide within the cylinder 11 via the column 12, achieving initial damping in conjunction with damping oil. Rotating the threaded baffle 16 adjusts the distance between the spring 13 and the threaded baffle 16. When the spring 13 abuts against the threaded baffle 16 and the column 12 continues to slide into the cylinder 11, the spring 13 is stressed, achieving dual damping in conjunction with the damping oil. The position of the threaded baffle 16 is adjustable, changing the trigger position of the spring 13 and thus adjusting the damping capacity of the damper. The second damping component 2 is threaded... After being installed in the threaded through hole 3a of the connecting seat 3, the first shock absorber 1 and the second shock absorber 2 are connected as a whole. By rotating the second shock absorber 2, its position on the connecting seat 3 can be adjusted, thereby changing the overall length of the first shock absorber 1 and the second shock absorber 2 to adapt to different models of washing machines. The two threaded rings 4 can fix the position of the connecting seat 3 on the second shock absorber 2 to prevent it from loosening. The threaded connection holes 3b on the bottom surface of the connecting seat 3 and the bottom end of the drum 11 are used to connect and install the shock absorber with the washing machine and other components.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
