Description

Technical Field

[0001] The utility model relates to the field of shock absorbers, and particularly to a washing machine shock absorber with a moisture-proof function. Background Technique

[0002] With the continuous progress of technology and the increasing improvement of people's living standards, washing machines have become one of the indispensable electrical appliances in family life. During the working process of a washing machine, the high-speed rotation of the motor and the rotation of the inner cylinder will generate relatively large vibrations and noises, which will not only affect the service life of the washing machine, but also bring an unpleasant user experience to users. To solve this problem, washing machine shock absorbers came into being.

[0003] Existing washing machine shock absorbers generally consist of a damping telescopic rod and a spring, with both ends used for fixation, and they achieve shock absorption through expansion and contraction during vibration. However, since the usage environment of washing machine shock absorbers is often accompanied by water vapor, it is easy to cause rust or water ingress of the spring and the damping telescopic rod, and over time, the usage effect deteriorates and the service life is relatively low.

[0004] Therefore, it is very necessary to propose a washing machine shock absorber with a moisture-proof function to solve the above problems. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a washing machine shock absorber with a moisture-proof function, which can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A washing machine shock absorber with a moisture-proof function includes a damping telescopic rod, fixed ends arranged at both ends of the damping telescopic rod, and a damping telescopic rod arranged outside the damping telescopic rod. A telescopic hose is sleeved outside the damping telescopic rod, and connection sleeves detachably connected to the fixed ends are symmetrically and fixedly arranged at both ends of the telescopic hose;

[0008] The fixed end is cylindrical, and one end of the fixed end close to the damping telescopic rod is open. A ventilation pipe for air inlet and outlet penetrates through the end of the fixed end located below and far from the damping telescopic rod, and a desiccant is arranged inside the ventilation pipe.

[0009] Preferably, the inner diameter of the connection sleeve is adapted to the diameter of the fixed end. A fastener is threadedly connected to the side wall of the connection sleeve, a threaded hole corresponding to the fastener is arranged on the side wall of the fixed end, and one end of the fastener is used for threaded cooperation with the threaded hole.

[0010] Preferably, a sealing assembly is provided on the fixed end head. The sealing assembly includes an annular groove provided on the outer side of the fixed end head near one end of the damping telescopic rod. A sealing ring is provided on the inner side of the annular groove. The sealing ring is circular and has a hollow structure. A groove corresponding to the fastener is provided on the outer side of the fixed end head away from the damping telescopic rod. A slider is movably connected along the radial direction of the fixed end head on the inner side of the groove. The threaded hole is provided on the slider. An airbag is provided at the end of the inner side of the groove. One end of the airbag is provided with a thin tube extending to the inner side of the annular groove and communicating with the sealing ring.

[0011] Preferably, when one end of the fastener is in a fastened state with the threaded hole, the outer side of the sealing ring is expanded and pressed against the inner wall of the connecting sleeve.

[0012] Preferably, the fastener is a bolt.

[0013] Preferably, the desiccant is detachably arranged inside the end of the ventilation pipe through a fixing component. The fixing component includes an end cap threadedly connected to the outer side of the outer end of the ventilation pipe. An inner cylinder for plugging and mating with the inner side of the end of the ventilation pipe is fixedly arranged on the inner side of the end cap. The desiccant is arranged inside the inner cylinder.

[0014] Preferably, a through hole with an inner diameter smaller than the inner diameter of the inner cylinder is provided at one end of the end cap away from the ventilation pipe.

[0015] Preferably, the desiccants are staggered on both sides of the inner cavity of the inner cylinder.

[0016] Compared with the prior art, the present utility model provides a washing machine shock absorber with a moisture-proof function, having the following beneficial effects:

[0017] 1. For the washing machine shock absorber with a moisture-proof function, the telescopic hose provided is located outside the damping telescopic rod and the spring, which can play a moisture-proof role, greatly reducing the corrosion of water vapor. Moreover, it is fixed on the fixed end head through the connecting sleeve, facilitating the synchronous expansion and contraction of the spring and the damping telescopic rod. The ventilation pipe facilitates the intake and exhaust of air when the telescopic hose expands and contracts. Moreover, the ventilation pipe is located on the lower fixed end head with its bottom facing downwards, reducing the entry of water vapor while allowing intake and exhaust of air. The desiccant can dry the incoming water vapor.

[0018] 2. For the washing machine shock absorber with a moisture-proof function, the sealing assembly provided can automatically seal between the connecting sleeve and the fixed end head when the connecting sleeve is fastened, preventing water vapor from entering through the connection between the connecting sleeve and the fixed end head.

[0025] As Figures 1-4 shown, a washing machine shock absorber with a moisture-proof function includes a damping telescopic rod 6, fixed ends 3 provided at both ends of the damping telescopic rod 6, and a damping telescopic rod 6 provided outside the damping telescopic rod 6. A telescopic hose 1 is sleeved outside the damping telescopic rod 6. Connecting sleeves 2 detachably connected to the fixed ends 3 are symmetrically and fixedly provided at both ends of the telescopic hose 1. Specifically, the inner diameter of the connecting sleeve 2 is adapted to the diameter of the fixed end 3. A fastener 4 is threadedly connected to the side wall of the connecting sleeve 2. The fastener 4 is preferably a bolt. A threaded hole 14 corresponding to the fastener 4 is provided on the side wall of the fixed end 3, and one end of the fastener 4 is used for threaded cooperation with the threaded hole 14;

[0026] In order to increase the sealing performance between the connecting sleeve 2 and the fixed end 3, a sealing assembly is provided on the fixed end 3. The sealing assembly includes an annular groove 10 provided on the outer side of the fixed end 3 near one end of the damping telescopic rod 6. A sealing ring 7 is provided inside the annular groove 10. The sealing ring 7 is circular and has a hollow structure. A groove 11 corresponding to the fastener 4 is provided at the outer end of the fixed end 3 away from the damping telescopic rod 6. A slider 13 is movably connected along the radial direction of the fixed end 3 inside the groove 11. The threaded hole 14 is provided on the slider 13. An airbag 12 is provided at the inner end of the groove 11. One end of the airbag 12 is provided with a thin tube 15 extending to the inside of the annular groove 10 and communicating with the sealing ring 7, configured such that when one end of the fastener 4 is in a tightened state with the threaded hole 14, the outer side of the sealing ring 7 is expanded and pressed against the inner wall of the connecting sleeve 2.

[0027] Further, the fixed end 3 is cylindrical, and the end of the fixed end 3 close to the damping telescopic rod 6 is open. A ventilation pipe 9 for air inlet and outlet is provided through the end of the fixed end 3 located below and away from the damping telescopic rod 6. A desiccant 18 is arranged inside the ventilation pipe 9. In order to facilitate the replacement of the desiccant 18, the desiccant 18 is detachably arranged inside the end of the ventilation pipe 9 through a fixing component. The fixing component includes an end cap 8 threadedly connected to the outside of the outer end of the ventilation pipe 9. An inner cylinder 17 for plugging and mating with the inner side of the end of the ventilation pipe 9 is fixedly arranged inside the end cap 8.
