Description

Integrated small-friction boom assembly Technical Field The utility model relates to the technical field of washing machine structures, in particular to an integrated low-friction boom assembly. Background The washing machine is mainly divided into a pulsator washing machine, a drum washing machine and a stirring washing machine, except the drum washing machine, a water holding barrel or a dewatering barrel of other washing machines needs to be fixed on a box body of the washing machine by a suspension system, a hanging rod type suspension system is commonly used, a hanging rod assembly consists of a hanging rod and a suspension angle, the hanging rod assembly is additionally provided with a gasket, a spring seat, a pressure spring and a spring sleeve assembled at the bottom of the hanging rod to form the suspension system, 4 groups of nest seats which are fixed on the box body and connected with the water holding barrel are arranged at the periphery of the water holding barrel or the dewatering barrel to play a role of suspending the water holding barrel or the dewatering barrel, and because vibration is inevitably generated by the water holding barrel in the washing process of the washing machine, the generated force can act on the suspension system to be borne by the hanging rod assembly, so the hanging rod of the washing machine is an important part of the washing machine, and the strength of the hanging rod directly relates to whether the washing machine can perform normal washing work or not. The Chinese patent publication No. CN213173007U discloses a hanger rod of a washing machine in 2021-05-11 days, which comprises a hanger rod, wherein a sliding block device is sleeved on the hanger rod, a spring is arranged between the sliding block device and a lower support of the spring, the sliding block device comprises an upper sliding block, a damping sleeve and a lower sliding block, the lower sliding block is of an integrated structure and comprises an inward concave cavity with one side open and an annular connecting part, one side of the opening of the inward concave cavity is connected with the annular connecting part, the upper sliding block is of an integrated structure and comprises a clamping part and a buffer part, a bulge is arranged on the clamping part and fixedly connected with the annular connecting part, the bulge is inserted into the inward concave cavity, a damping sleeve accommodating cavity is formed between the bulge and the inward concave cavity, and the damping sleeve accommodating cavity is internally provided with the damping sleeve. The damping sleeve accommodating cavity is a closed cavity, the condition that the damping sleeve is exposed outside is overcome, noise generated by gas in the damping sleeve accommodating cavity is avoided, the noiseless environment-friendly effect is achieved, the structure is reasonable, the assembly is convenient, and the use is simple. However, the above-mentioned disclosed solution has the disadvantage that the upper slider and the lower slider of the prior art are combined for achieving the purpose of damping for two structures, but the cost of manufacturing two parts is greater than the cost of manufacturing one part, and in order to reduce the manufacturing cost, the cost can be saved by designing a plurality of parts as one whole for one-time processing. Disclosure of utility model The utility model aims to solve the technical problems that in the prior art, an upper sliding block and a lower sliding block are combined into two structures to achieve the purpose of damping, but the cost for manufacturing two parts is greater than that for manufacturing one part, and in order to reduce the manufacturing cost, a plurality of parts are designed into a whole for one-time processing, so that the cost can be saved, and an integrated small-friction suspender assembly is provided.
