Abstract
Description
Technical Field
[0001] This utility model relates to the field of washing machine shock absorber technology, specifically a washing machine shock absorber with an adjustment mechanism. Background Technology
[0002] During operation, washing machines generate vibrations due to the rotation of the drum. The shock absorber is a crucial component for reducing vibration transmission and ensuring stable operation. Traditional washing machine shock absorbers have a fixed structure, relying solely on damping oil to dampen the column and reduce vibration. This lack of flexibility, coupled with a simplistic cushioning structure, leads to a significant decrease in damping effectiveness over time, failing to meet diverse vibration reduction needs. Therefore, designing a washing machine shock absorber with adjustable damping trigger position and compression stroke is an urgent problem to be solved. Utility Model Content

The main threaded sleeve is threaded onto the outside of the main cylinder. A secondary sleeve is fixedly connected to the outer wall of the main threaded sleeve, and a secondary cylinder is fitted inside the secondary sleeve. A cylinder mounting lug is fixedly connected to the outer wall at the top of the main cylinder. A secondary cylinder adapted to the secondary cylinder is fixedly installed on the bottom surface of the cylinder mounting lug. The secondary cylinder is slidably disposed in the secondary cylinder. A cylinder groove adapted to the secondary cylinder is opened on the bottom surface of the cylinder mounting lug. A threaded hole is opened on the top of the secondary cylinder. The secondary cylinder is fixed to the cylinder mounting lug by a cylinder fixing bolt. The bottom of the secondary cylinder has a conical structure.
[0005] Preferably, both the main cylinder and the auxiliary cylinder are hollow structures with sealed bottoms, and are filled with damping oil.
[0006] Preferably, the main cylinder has a threaded part on its exterior, and the inner wall of the secondary sleeve can be either a threaded or smooth wall structure. A positioning bolt is threaded through one side of the secondary sleeve, and a rubber anti-slip pad is provided at one end of the positioning bolt.
[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0008] This utility model has a clever structure. By using the threaded engagement between the main cylinder and the main threaded sleeve, combined with the adjustment structure of the auxiliary sleeve and the auxiliary cylinder, the damping trigger position of the auxiliary column entering the auxiliary cylinder can be flexibly adjusted, increasing the damping and buffering effect of the device and adapting to different shock absorption requirements. The rubber buffer at the bottom of the main column can adjust the compression stroke and can buffer impacts and reduce noise. Attached Figure Description

[0014] 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.
[0015] Please see Figures 1 to 4This utility model provides a technical solution: a washing machine shock absorber with an adjustment mechanism, comprising a main drum 1 and a main column 2. The main column 2 is slidably sleeved inside the main drum 1. A rubber buffer 7 is threadedly installed at the bottom end of the main column 2, and a threaded post 6 is fixedly connected to the top end of the rubber buffer 7. A threaded hole is opened at the bottom end of the main column 2, and the threaded post 6 is threadedly installed in the threaded hole of the main column 2. The main drum 1 has a threaded part on its exterior, and an adjustment structure is threadedly sleeved on the exterior of the main drum 1. The adjustment structure includes a main threaded sleeve 3, which is threadedly sleeved on the main drum 1. Externally, a secondary sleeve 301 is fixedly connected to the outer wall of the main threaded sleeve 3. A secondary cylinder 4 is threaded onto the inner wall of the secondary sleeve 301. A cylinder mounting ear 21 is fixedly connected to the outer wall of the top of the main cylinder 2. A secondary cylinder 5 adapted to the secondary cylinder 4 is fixedly installed on the bottom surface of the cylinder mounting ear 21. The secondary cylinder 5 is slidably disposed inside the secondary cylinder 4. A cylinder groove 23 adapted to the secondary cylinder 5 is opened on the bottom surface of the cylinder mounting ear 21. A threaded hole is opened on the top of the secondary cylinder 5. The secondary cylinder 5 is fixed to the cylinder mounting ear 21 by a cylinder fixing bolt 22. The bottom of the secondary cylinder 5 has a conical structure.
[0016] Furthermore, both the main cylinder 1 and the secondary cylinder 4 are hollow structures with sealed bottoms, and their interiors are filled with damping oil.
[0017] Furthermore, the main cylinder 1 has a threaded part on its exterior, and the inner wall of the auxiliary sleeve 301 adopts a threaded structure.
[0018] The working process of this utility model is as follows:
[0019] like Figure 1 - Figure 4 As shown, during device use, damping oil is added to both the main cylinder 1 and the auxiliary cylinder 4. The position of the main threaded sleeve 3 on the main cylinder 1 is adjustable, and the position of the auxiliary cylinder 4 on the auxiliary sleeve 301 is also adjustable. The effective damping trigger position of the auxiliary column 5 entering the auxiliary cylinder 4 can be adjusted as needed. For example, when the main column 2 compresses 5-7cm into the main cylinder 1, the auxiliary column 5 contacts the damping trigger position of the auxiliary cylinder 4, thereby enhancing damping. A rubber buffer 7 is also installed at the bottom of the main column 2. By rotating the rubber buffer 7 through the thread, its position relative to the bottom of the main column 2 can be adjusted, changing the maximum compression stroke of the main column 2. At the same time, when the rubber buffer 7 contacts the bottom of the main cylinder 1, it can effectively buffer the impact of the main column 2 on the main cylinder 1, reducing the noise generated by vibration.
[0020] 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.
