Description
Technical Field
The utility model relates to a washing machine technical field, concretely relates to jib shock absorber.
Background
The suspension system is that rotary drum washing machine's important damping is constituteed, generally comprises four jib shock absorbers, and traditional jib shock absorber carries out the damping through the spring, but does not set up damping system on the shock absorber, and in the short time, when load on the jib shock absorber takes place great change, the length of spring is replied fast and is caused the vibration, is unfavorable for practical use.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a jib shock absorber to solve the problem that proposes among the above-mentioned background art.
The utility model provides a jib shock absorber, includes the metal pole, the one end of metal pole is fixed with the damping piece, still cup joint elasticity vibration-damping structure on the metal pole, the one end of elasticity vibration-damping structure is fixed on the damping piece, still sliding connection has the damping sleeve on the metal pole, the other end of elasticity vibration-damping structure is connected on the interior top surface of damping sleeve, be provided with the friction strip between damping piece and the damping sleeve.
Preferably, the damping sleeve comprises a sleeve and an end cover fixed at one end of the sleeve, the end cover is connected to the metal rod in a sliding mode, and the end cover is connected with the elastic vibration damping structure.
Preferably, the elastic vibration damping structure comprises a spring and an elastic steel sheet, the length of the elastic steel sheet is shorter than that of the spring, the rigidity of the elastic steel sheet is larger than that of the spring, the spring and the elastic steel sheet are both sleeved on the metal rod, one ends of the spring and the elastic steel sheet are both fixed on the damping block, and the other end of the spring is connected with the end cover.
Preferably, the damping block is provided with an annular groove, and the friction strip is fixed in the annular groove and is tightly attached to the inner surface of the sleeve.
Preferably, the other end of the metal rod is provided with a top cover.
The utility model has the advantages that: the damping system composed of the damping block, the sleeve and the friction strip is arranged, so that when the load on the shock absorber changes greatly in a short time, the length of the spring changes slowly, the generation of vibration is reduced, and the use is more convenient.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 to 3, a suspension rod shock absorber includes a metal rod 1, a damping block 2 is fixed at one end of the metal rod 1, an elastic vibration reduction structure 3 is further sleeved on the metal rod 1, one end of the elastic vibration reduction structure 3 is fixed on the damping block 2, a damping sleeve 4 is further slidably connected on the metal rod 1, the other end of the elastic vibration reduction structure 3 is connected on the inner top surface of the damping sleeve 4, and a friction strip 5 is arranged between the damping block 2 and the damping sleeve 4.
In this embodiment, the damping sleeve 4 includes a sleeve 401 and an end cap 402 fixed at one end of the sleeve 401, the end cap 402 is slidably connected to the metal rod 1, the end cap 402 is connected to the elastic vibration damping structure 3, and the damping sleeve 4 is in a split structure so as to be conveniently connected to the elastic vibration damping structure 3.
In this embodiment, the elastic vibration damping structure 3 includes a spring 301 and an elastic steel sheet 302 having a length shorter than that of the spring 301 and a rigidity greater than that of the spring 301, the spring 301 and the elastic steel sheet 302 are both sleeved on the metal rod 1, one ends of the spring 301 and the elastic steel sheet 302 are both fixed on the damping block 2, and the other end of the spring 301 is connected with the end cover 402.
In this embodiment, the damping block 2 is provided with an annular groove 201, the friction bar 5 is fixed in the annular groove 201 and is tightly attached to the inner surface of the sleeve 401, and the annular groove 201 is used for limiting the friction bar 5 and preventing the friction bar 5 from sliding due to friction.
In this embodiment, the other end of the metal rod 1 is provided with a top cover 6.
Working principle and process, when end cover 402 received the light load, spring 301 received the compression to shorten and with end cover 402 support column, when the load was bigger, spring 301 continued to shorten, supported end cover 402 by the higher elastic steel piece 302 of intensity, when end cover 402 slided on metal pole 1, the sliding speed of end cover 402 was restricted to the frictional force between 5 and the sleeve 401 of friction strip for the shock absorber can't produce great vibration, convenient and practical.
It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of the invention or which are equivalent to the scope of the invention are embraced by the invention.
