Description

Technical Field

[0001] This utility model relates to the field of washing machine structure technology, specifically an integrated small friction type suspension rod assembly. Background Technology

[0002] Washing machines are mainly classified into the following categories: top-loading washing machines, front-loading washing machines, and agitator washing machines. Except for front-loading washing machines, the other types of washing machines require a suspension system to fix the water tank or spin-drying tub to the washing machine body. The most common type is the hanger-type suspension system. The hanger assembly consists of a hanger rod and a suspension bracket. The hanger assembly, along with the washer, spring seat, compression spring, and spring sleeve mounted at the bottom of the hanger rod, constitutes the suspension system. Four sets of brackets are set around the water tank or spin-drying tub and fixed to the body to connect to the water tank, which serves to suspend the water tank or spin-drying tub. Since the water tank inevitably vibrates during the washing process, the resulting force is borne by the hanger assembly on the suspension system. Therefore, the washing machine hanger is an important part of the washing machine, and its strength directly affects whether the washing machine can perform normal washing operations.

[0003] Chinese utility model patent CN213173007U, published on May 11, 2021, discloses a washing machine hanging rod, including a hanging rod with a slider device sleeved on it. A spring is arranged between the slider device and a spring support. The slider device includes an upper slider, a damping sleeve, and a lower slider. The lower slider is an integrally formed structure, including a concave cavity with an opening on one side and an annular connecting part. The annular connecting part is connected to the opening side of the concave cavity. The upper slider is an integrally formed structure, including a snap-fit ​​part and a buffer part. The snap-fit ​​part has a protrusion, which is fixedly connected to the annular connecting part. The protrusion is inserted into the concave cavity, forming a damping sleeve receiving cavity between the protrusion and the concave cavity. A damping sleeve is disposed in the damping sleeve receiving cavity. The damping sleeve receiving cavity of this utility model is a closed chamber, overcoming the situation where the damping sleeve is exposed, avoiding noise generated by gas in the damping sleeve receiving cavity, achieving a noiseless and environmentally friendly effect. It has a reasonable structure, is easy to assemble, and is simple to use.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: the existing technology uses two structural combinations of upper and lower sliders to achieve the purpose of damping, but the cost of manufacturing two parts is greater than the cost of manufacturing one part. In order to reduce manufacturing costs, designing multiple parts as a whole and processing them in one go can save costs. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the existing technology uses two structural combinations of upper and lower sliders to achieve damping, but the cost of manufacturing two parts is greater than the cost of manufacturing one part. In order to reduce manufacturing costs, multiple parts are designed as a whole and processed in one go, which can save costs. This invention provides an integrated small friction rod assembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] The present invention discloses an integrated small friction type suspension rod assembly, comprising an integrally formed limiting cover and a reinforcing friction tube; a first friction hole is formed inside the limiting cover and the reinforcing friction tube; a hollow cover is fixedly connected to the lower end of the limiting cover; a damping block is inserted into the hollow cover; a second friction hole is formed inside the damping block; and multiple limiting bosses are fixedly connected to the hollow cover corresponding to the damping block.

[0008] Furthermore, a lifting rod is slidably inserted into the first friction hole and the second friction hole.

[0009] The integrated low-friction type suspension rod assembly provided by this utility model has the following beneficial effects:

[0010] 1. This utility model is made by integrating the limiting cover and the reinforcing friction tube, thereby reducing the number and cost of injection molds. Then, the hollow cover, together with the limiting boss, can insert the damping block into multiple hollow covers by external force for limiting. Then, this device is sleeved on the lifting rod, and can be hoisted into the washing machine for buffering and shock absorption, while reducing the mold opening and manufacturing cost of injection molded parts.

[0011] 2. This utility model can be connected and fixed to the hanging structure inside the washing machine through the ball seat, and can be connected to the drum body through the reinforced friction tube and the limiting cover, so that the weight of the drum body can be transferred to the reinforced friction tube, the limiting cover and the elastic element for buffering and shock absorption.

Detailed Implementation

[0018] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0021] Please see Figure 1-3 As shown, an integrated small friction-type lifting rod assembly includes an integrally formed limiting cover 8 and a reinforcing friction tube 9; a first friction hole 14 is formed inside the limiting cover 8 and the reinforcing friction tube 9; a hollow cover 13 is fixedly connected to the lower end of the limiting cover 8; a damping block 10 is inserted into the hollow cover 13; a second friction hole 15 is formed inside the damping block 10; multiple limiting bosses 12 are fixedly connected to the hollow cover 13 corresponding to the damping block 10. By integrally forming the limiting cover 8 and the reinforcing friction tube 9, the number and cost of injection molds are reduced. Then, the hollow cover 13, in conjunction with the limiting bosses 12, can insert the damping block 10 into multiple hollow covers 13 by external force for limiting. Then, this device is sleeved on the lifting rod 1, and can be hoisted into the washing machine for buffering and shock absorption, while reducing the mold opening and manufacturing costs of injection molded parts.

[0022] A suspension rod 1 is slidably inserted into the first friction hole 14 and the second friction hole 15. The device can be connected to the washing machine shell and the drum through the suspension rod 1, so that the drum can be suspended and damped.

[0023] The upper end of the suspension rod 1 is provided with a bent part 5; a ball seat 2 is sleeved on the suspension rod 1 and the bent part 5; a limiting groove 3 is opened on the ball seat 2 corresponding to the bent part 5; a locking protrusion 4 is symmetrically fixed to the limiting groove 3 corresponding to the bent part 5. The ball seat 2 can be connected and fixed to the hanging structure inside the washing machine. The ball seat 2 can be connected to the drum body through the reinforced friction tube 9 and the limiting cover 8, so that the weight of the drum body can be transferred to the reinforced friction tube 9, the limiting cover 8 and the elastic element 7 for buffering and shock absorption.

[0024] The lower end of the hanging rod 1 is fixedly connected to the lower bracket 6; the lower bracket 6 and the hanging rod 1 are fitted with an elastic element 7. The displacement of the elastic element 7 is restricted by the lower bracket 6, so that the vibration transmitted from the whole washing machine can be absorbed by the damping block 10, thereby buffering and shock absorption.

[0025] Multiple limiting reinforcing ribs 11 are fixed to the lower surface of the damping block 10 corresponding to the hollow cover 13. The limiting reinforcing ribs 11 increase the structural strength of the hollow cover 13, so that the damping block 10 can be stably confined within the hollow cover 13, thereby playing the function of damping, buffering and shock absorption.

[0026] The recess of the limiting reinforcing rib 11 is aligned with the elastic element 7, so that the upper end of the elastic element 7 can be restricted by the limiting reinforcing rib 11, thereby making the compression process of the elastic element 7 precise and stable, without generating excessive displacement and causing unnecessary friction.
