Description
Technical Field
The utility model relates to a washing machine technical field, concretely relates to shock absorber.
Background
A suspension system is an important vibration damping mechanism of a pulsator washing machine and generally comprises four suspender vibration dampers, only one linear spring with constant rigidity coefficient is arranged on the traditional suspender vibration damper, under the dehydration condition, when the load mass is light, a small rigidity spring can exert good damping effect, a large rigidity spring can easily cause that a cylinder body is violent up and down, the sound is abnormal, the vibration damping effect is poor, when the load mass is heavy, the large rigidity spring is needed, the small rigidity spring can not meet the bearing capacity and pressure, the vibration damping effect is poor, and even the spring is forced to fail and deform. Thus, the single rate spring of the conventional boom fails to meet the multi-rate damping requirements.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a shock absorber to solve the problem that proposes among the above-mentioned background art.
A shock absorber comprises a metal rod, wherein one end of the metal rod is in threaded connection with a fixed block, a first elastic element and a second elastic element are further sleeved on the metal rod in a sleeved mode, the length of the first elastic element is larger than that of the second elastic element, the rigidity of the first elastic element is smaller than that of the second elastic element, the first elastic element is sleeved outside the second elastic element, one ends of the first elastic element and the second elastic element are connected with the fixed block, and the other end of the first elastic element is connected with a sliding block which is connected to the metal rod in a sliding mode.
Preferably, the first elastic element and the second elastic element are both springs.
Preferably, the first elastic element and the second elastic element are mounted on the fixed block.
Preferably, an end cover I is arranged at the end part of the elastic element I, the end cover I is installed on the elastic element I, and the end cover I is in threaded connection with the sliding block.
Preferably, a second end cover is mounted at the end of the second elastic element.
Preferably, the other end of the metal rod is provided with a top cover.
The utility model has the advantages that: the variable-stiffness spring is formed by the elastic element I and the elastic element II, so that the function of different spring stiffness required by the suspension rod under different load conditions is realized, namely the spring stiffness value is small under the condition of small mass load and is large under the condition of large mass load, and the multi-stiffness damping requirement of the shock absorber during use is met.

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, the shock absorber includes a metal rod 1, one end of the metal rod 1 is screwed with a fixed block 2, the metal rod 1 is further sleeved with a first elastic element 3 and a second elastic element 4, the length of the first elastic element 3 is greater than that of the second elastic element 4, the rigidity of the first elastic element 3 is smaller than that of the second elastic element 4, the first elastic element 3 is sleeved outside the second elastic element 4, one ends of the first elastic element 3 and the second elastic element 4 are connected with the fixed block 2, and the other end of the first elastic element 3 is connected with a slider 5 slidably connected to the metal rod 1.
In this embodiment, the first elastic element 3 and the second elastic element 4 are both springs.
In this embodiment, the first elastic element 3 and the second elastic element 4 are mounted on the fixing block 2.
In this embodiment, an end cover one 6 is disposed at an end of the elastic element one 3, the end cover one 6 is mounted on the elastic element one 3, and the end cover one 6 is screwed with the sliding block 5.
In this embodiment, the end of the second elastic element 4 is provided with a second end cover 7, and the second end cover 7 is used for enabling the second elastic element 4 to be stressed more uniformly when being pressed.
In this embodiment, the other end of the metal rod 1 is provided with a top cover 8.
In this embodiment, the fixing block 2 is screwed with the metal rod 1, and the first end cover 6 is screwed with the sliding block 5, so that the assembly of the shock absorber is more convenient.
The working principle and the process are as follows: when the end cover slide block is used, when the slide block 5 is under light load, only the first elastic element 3 is compressed and shortened and supports the slide block 5, when the load is larger, the first elastic element 3 is continuously shortened until the slide block 5 is pressed on the second end cover 7, at the moment, the second elastic element 4 with higher strength and the first elastic element 3 support the end cover slide block 5 together, therefore, under the two conditions of light load and heavy load, the elastic part supporting the slide block 5 can also change the rigidity, and the vibration reduction effect of the vibration reducer is ensured.
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.
