Description

Technical Field

[0001] The invention relates to a spring seat, in particular to a spring seat for a closed air resistance suspension rod. Background Art

[0002] At present, the washing machine suspension system adopts internal spring shock absorption, and utilizes the friction resistance and air resistance between the compression spring and the shock-absorbing rubber seat in the component and the inner wall of the damping sleeve to absorb the vibration of the washing machine, so as to achieve the shock absorption effect of the washing machine during the dehydration process.

[0003] During the use of the closed air resistance hanger, a spring seat is needed to support the spring, and most of the existing spring seats are in a sealed state. When the spring seat is pulled by the hanger, the pressure inside the sealed hanger will change. This pressure change can easily cause the spring seat to shift inside the sealed hanger, which can easily cause damage to the spring seat. Therefore, we propose a spring seat for a closed air resistance hanger. Summary of the invention

[0008] Preferably, four groups of mutually symmetrical reinforcing ribs are fixedly connected to the top of the support block and the outer surface of the support seat.

[0009] Preferably, the surface of the support block is provided with a raised knurled surface.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The present invention can balance the internal pressure of the sealed suspension rod by providing a second through hole, thereby preventing the spring seat from being deflected due to the change in the internal pressure of the sealed suspension rod;

[0012] 2. The gasket can provide a certain support to the support block, preventing the support block from bending due to pressure changes when it moves inside the sealed boom;

[0013] 3. The spring arranged inside the friction pad can provide a certain support to the outer surface of the friction pad, thereby preventing gas leakage from occurring when the friction pad slides along the inside of the sealed suspension rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-4The present invention provides a technical solution: a spring seat for a closed air resistance hanger, comprising a support block 1, a gasket 6 is fixedly connected to the inside of the support block 1, the support block 1 and the gasket 6 are manufactured in an integrated molding manner, the manufacturing material of the gasket 6 is a rigid material, and the setting of the gasket 6 made of rigid material can make the support block 1 have a certain rigidity to prevent the support block 1 from bending due to pressure changes when it moves inside the sealed hanger, a friction pad 2 is fixedly installed on the top of the outer surface of the support block 1, a support seat 3 is fixedly installed in the middle of the support block 1, a first through hole 4 is penetrated at the center axis of the surface of the support seat 3, the setting of the first through hole 4 can make the stretching rod of the sealed hanger pass through the inside of the first through hole 4, the bottom of the first through hole 4 penetrates the surface of the support block 1 and the gasket 6, the surface of the support block 1 is penetrated by symmetrically distributed second through holes 5, and the bottom of the second through hole 5 sequentially penetrates the surface of the support block 1 and the gasket 6.

[0022] Preferably, the friction pad 2 is configured to be conical, and the opening diameter of the friction pad 2 on the side close to the surface of the support block 1 is smaller than the opening diameter of the friction pad 2 on the side away from the surface of the support block 1 .

[0023] Preferably, the inner wall of the friction pad 2 is provided with a mounting groove 8, and a spring 9 is embedded in the mounting groove 8. The two ends of the spring 9 are fixedly connected by a connecting piece 10, and the connecting piece 10 is arranged in an arc shape. The spring 9 arranged inside the friction pad 2 can play a certain supporting role on the outer surface of the friction pad 2, so that the outer wall of the friction pad 2 is always in contact with the inner wall of the sealed hanger. This contact setting can, on the one hand, make the outer wall of the friction pad 2 always in contact with the inner wall of the sealed hanger to increase the friction elastic force, and on the other hand, it can prevent the occurrence of gas leakage when the friction pad 2 slides along the inside of the sealed hanger.

[0024] Preferably, four groups of mutually symmetrical reinforcing ribs 7 are fixedly connected to the top of the support block 1 and the outer surface of the support seat 3.

On the one hand, this contact setting can make the outer wall of the friction pad 2 always in contact with the inner wall of the sealed hanger to increase the friction elastic force. On the other hand, it can prevent the occurrence of gas leakage when the friction pad 2 slides along the inside of the sealed hanger. When the friction pad 2 slides along the inside of the sealed hanger, the second through hole 5 on the surface of the support block 1 will balance the air pressure on both sides of the support block 1 and the friction pad 2. This setting can prevent the spring seat from being offset due to the pressure change inside the sealed hanger.
