Detailed Description
To explain the technical solution disclosed in the present invention in detail, the following description is further made with reference to the drawings and specific examples.
The utility model provides a car washer shock attenuation buffer gear also can be applicable to the buffering shock attenuation that the arm on the non-automatic car washing equipment resets, in the motion process.
As shown in connection with fig. 1-5. The present embodiment is a cylindrical design, and is assembled and installed in a manner of a sleeve. The damping and buffering mechanism of the car washer mainly comprises an outer sleeve 1 and an ejector rod 2, wherein the outer sleeve 1 is a shell and is used for being installed and fixed on a rack and comprises welding installation or bolt fixing and other modes. In outer sleeve 1, ejector pin 2 runs through wherein, 2 one ends of ejector pin extend to outer sleeve 1 outsidely, are connected with collision portion 3 and are used for bearing the impact top that comes from the arm and hit, to ejector pin 2 generally adopt steel structure, including solid construction with the reinforcing atress, to collision portion 3, can adopt steel to realize hard contact, and can set up the recess in order to match rather than the arm shape of contact for better laminating contact, transmission impact force to ejector pin 2, and then through the 4 compression buffering of spring. On the other hand, the collision part 3 may be made of rubber to provide a first buffer and achieve a soft contact. For convenient replacement, the collision part 3 is connected with the mandril 2 through threads.
As one of the installation methods of the spring 4, the spring 4 is wound around the periphery of the ejector rod 2 and inside the outer sleeve 1, the spring 4 is located in a limit area of the ejector rod 2, the limit area is composed of a pair of limit plates 401, the limit on the ejector rod 2 near the collision part 3 can be installed in a limit plate mode, the upper limit plate 401 is fixed with the ejector rod 2, and the spring is compressed towards the bottom of the outer sleeve 1 under the condition that the ejector rod 2 is pressed. Preferably, the upper limiting plate 401 can be expanded to a cylindrical structure against which the collision part 3 abuts, so that the force pressure of the mandril 2 can be relieved to a certain extent. One end that is close to outer sleeve 1 bottom at spring 4 is equipped with the second floor limiting plate, and this limiting plate prevents spring 4 toward the compression of outer sleeve 1 bottom, and the spacing hole adjusting position that the second floor limiting plate can set up on through outer sleeve 1 is fixed in limiting plate both sides, the anchor clamps limiting plate, and this mode helps the deformation according to different stroke adjusting spring 4. Alternatively, it may be directly fixed to the inner wall of the outer sleeve 1.
The utility model discloses an operating condition is: the damping and buffering mechanism is arranged on the automatic carwash frame according to the angle, and one of the installation modes is shown in figure 5. The inner wall of the outer sleeve 1 is smooth and in most cases the damping mechanism is mounted facing upwards, forming an elevation angle. For the installation mode of depression angle, a bump can be arranged at the vacant position in the outer sleeve 1 to prevent the mandril 1 from sliding, for example, the first layer of limiting plate 401 is a sheet structure, and the inner wall of the outer sleeve 1 close to the collision part 3 is provided with a block through a limiting hole. Of course, the resistance to the sliding down of the mandrel 2 can also be achieved by adjusting the roughness of the inner wall of the outer sleeve 1. The collision part 3 urges the ejector rod 2 to press down after receiving impact force, and the spring 4 compresses, thereby realizing buffering. In order to ensure that the ejector rod 2 does not deviate, through holes are formed in the second layer of limiting plate (close to the bottom of the outer sleeve) and the bottom of the outer sleeve, and one end of the ejector rod moves in the through holes.
As another preferred scheme, on the basis of above-mentioned embodiment, the utility model discloses further promotion shock attenuation buffering effect, the sleeve that sets up in outer sleeve bottom and the tip stroke piston structure of ejector pin, telescopic bottom is sealed, and the tip of ejector pin is including setting up the sealing washer, after the ejector pin atress, piston structure forms the gas buffer area.
Car washer shock attenuation buffer gear, combine technical staff in the field to know, the familiar technological basis of using for reference, this mechanism adopts telescopic mode combination, the transmission of collision portion atress, ejector pin realization power, spring shock attenuation, the effect of offsetting force, and the elasticity degree through spacing district adjustable spring, the deformation distance that can adjustable spring that corresponds, the size of the impact that needs to treat through the different adaptations of compressive force. The mechanism is simple in structure, high in practicability, convenient and efficient, and is particularly applied to side arm damping prevention and buffering of a car washer.
