Description

Technical Field

[0001] This utility model relates to the technical field of car wash machine equipment, specifically to a novel car wash machine shock absorber. Background Technology

[0002] Current car wash machine shock absorbers generally use hydraulic shock absorbers. Their working principle relies on the flow of internal hydraulic oil to absorb and dissipate vibration energy, thereby suppressing equipment vibration and ensuring smooth operation. However, the design focus of these shock absorbers is often concentrated on meeting basic vibration reduction targets, lacking systematic protection against the extreme conditions unique to car washes, such as high temperature and humidity, and strong acids and alkalis. The outer shell and key components are easily corroded, rusted, and aged, ultimately leading to decreased vibration reduction performance and a significantly shortened service life.

[0003] Therefore, it is necessary to provide a new type of shock absorber for car wash machines to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a new type of car wash machine shock absorber that is less prone to corrosion even when exposed to high temperature, high humidity, strong acid, and strong alkali environments for extended periods, thereby improving durability and extending service life.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A novel car wash machine shock absorber includes an oil reservoir with a piston inside. A piston rod is fixed to the piston, and a pressure cap is fixedly connected to one end of the piston rod protruding outside the oil reservoir. The outer wall of the oil reservoir is covered with coaxial protective sleeves at intervals. A plastic dust cover is coaxially fitted onto the outside of the protective sleeves. One end of the plastic dust cover is fixedly connected to the pressure cap, and the other end has an outwardly flared, trumpet-shaped opening. During operation, the protective sleeves provide guidance for the plastic dust cover, effectively preventing the plastic dust cover from scratching the outer wall of the oil reservoir.

[0007] Preferably, the end of the plastic dust cover is provided with a slot, and the plastic dust cover is interference-fitted with the pressure cap through the slot.

[0008] Preferably, the outer wall of the oil reservoir adopts a double-layer paint structure, which makes the shock absorber less prone to corrosion even when exposed to high temperature, high humidity, strong acid and strong alkali environments for a long time.

[0009] Preferably, a first ball bearing is provided at the end of the piston rod protruding outside the oil reservoir, and a second ball bearing is provided at the opposite end of the oil reservoir. The ball bearings increase the swing angle of the shock absorber and improve the durability of the equipment.

[0010] Preferably, the ball bearing is fixed to the end of the shock absorber by a lifting ring sealing structure to prevent the bearing from coming off due to interference fit.

[0011] Compared with the prior art, this utility model has the following advantages: the outermost plastic dust cover of the car wash machine shock absorber can provide a durable rust-proof barrier for the equipment in long-term high temperature, high humidity and strong acid and alkali environments. The flared end of the plastic dust cover fits with the inner protective sleeve, eliminating the risk of scratching during the operation of the car wash machine shock absorber.

[0015] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only for illustrating the present invention and not for limiting the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0016] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "setting", "connection", "fixed connection", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] In this utility model, terms such as "upper", "lower", "bottom", and "top" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only used to facilitate the description of the structural relationship between the various components or elements of this utility model and do not specifically refer to any component or element in this utility model. They should not be construed as limiting this utility model.

[0018] like Figure 1 and Figure 2As shown, a novel car wash machine shock absorber includes an oil reservoir 1. The outer wall of the oil reservoir 1 has a double-layer painted structure, making it resistant to corrosion even when exposed to high temperature, high humidity, and strong acid / alkali environments for extended periods. A piston is installed inside the oil reservoir 1, and a piston rod 5 is fixed to the piston. A pressure cap 6 is fixedly connected to one end of the piston rod 5 protruding outside the oil reservoir. The outer wall of the oil reservoir 1 is covered with coaxial sheaths 2 at intervals. A plastic dust cover 3 is coaxially fitted over the outside of the sheaths 2, providing long-term rust prevention in high temperature, high humidity, and acid / alkali environments. One end of the plastic dust cover 3 has a groove 10, which allows it to be press-fitted with the pressure cap 6. The other end has an outwardly flared, trumpet-shaped opening 4. During operation, the sheaths 2 guide the plastic dust cover 3, effectively preventing it from scratching the outer wall of the oil reservoir 1. The piston rod 5 is provided with a first ball bearing 7 at the end protruding outside the oil reservoir 1, and a second ball bearing 8 is provided at the end of the oil reservoir 1 opposite to the other end. The ball bearing can significantly increase the swing angle of the car wash machine shock absorber and improve the durability of the equipment. The ball bearing is fixed to the end of the car wash machine shock absorber by the sealing structure of the lifting ring 9, which can prevent the bearing from coming off due to interference fit.

[0019] The principle and usage of a new type of car wash machine shock absorber: During operation, the car wash machine frame experiences vertical and lateral vibrations. This vibration energy is transmitted to the oil reservoir via the piston rod. The piston reciprocates within the reservoir, compressing the hydraulic oil and causing intense friction that generates heat. This heat is then dissipated through the cylinder wall. The shock absorber achieves its vibration damping purpose by converting kinetic energy into heat energy, ensuring stable equipment operation. The use of a plastic dust cover on the shock absorber allows it to withstand long-term exposure to high temperature, high humidity, and strong acid / alkali environments without easily corroding, significantly improving durability and extending its service life.

[0020] The foregoing description illustrates and describes preferred embodiments of the present invention. As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or related technical or knowledge. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
