Technical Field
[0001] The utility model relates to a closed spring shock absorber. Background Art
[0002] The spring shock absorber is used to be installed on the base of the equipment. Under the action of the gravity of the equipment, the spring is pressed downward, the spring deforms and contracts, and the elastic force of the spring is used to form a shock-absorbing effect.

[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0023] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.
[0024] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0025] like Figures 1 to 5As shown, this embodiment provides a closed spring shock absorber, including a closed base 1 with a hollow interior, a lifting body 2 is arranged inside the base, the bottom of the lifting body is connected to the inner bottom of the base via a shock-absorbing spring 3, the top of the lifting body extends to the outside through a clearance hole 4 opened at the top of the base and is fixedly connected to a detachable connecting plate 5, and a connecting part for fixing the bottom foot of the equipment is provided on the connecting plate.
[0026] In the embodiment of the utility model, the number of the shock absorbing springs is several and they are evenly distributed along the circumference of the inner bottom of the base, and preferably three shock absorbing springs are used.
[0027] In the embodiment of the utility model, the base is composed of a cylindrical shell 6 and an upper cover 7 .
[0028] In the embodiment of the utility model, the mouth of the cylindrical shell faces upward, the upper cover is fixedly connected to the mouth of the shell, and the clearance through hole is arranged on the top surface of the upper cover.
[0029] In the embodiment of the utility model, a skirt 8 extending downward is vertically fixed on the outer periphery of the upper cover, and the skirt is wrapped around the top periphery of the cylindrical shell.
[0030] In the embodiment of the utility model, a vertical guide sleeve 9 is coaxially fixed on the edge of the hole of the said yielding through hole.
[0031] In the embodiment of the utility model, a sliding guide block 10 passing through the guide sleeve is coaxially fixed at a position on the top surface of the lifting body corresponding to the position of the through hole.
[0032] In the embodiment of the utility model, a positioning boss 11 is fixedly provided on the inner bottom of the base for embedding the bottom of the shock absorbing spring.
[0033] In the embodiment of the utility model, the connecting plate is arranged on the top surface of the sliding guide block and is screwed to the sliding guide block via countersunk screws 12. There are three countersunk screws.
[0034] In the embodiment of the utility model, the connecting portion is an internal threaded hole 13 arranged in the middle of the connecting plate.
[0035] In another embodiment of the present invention, the connecting portion is an external thread column 14 disposed in the middle of the connecting plate.
[0036] In the embodiment of the utility model, the closed spring shock absorber has a simple structure, and the connecting plate is fixedly connected to the bottom foot of the equipment. Under the action of the gravity of the equipment, the lifting body moves downward, exerting pressure on the shock absorbing spring, which deforms and contracts, and utilizes the elastic force of the shock absorbing spring to form a shock absorbing effect. Among them, the shock absorbing spring is located inside and has a certain protective and dustproof effect; because the connecting plate is in direct contact with the equipment, the connecting plate is most susceptible to wear and paint peeling, leading to rust. If it is an integrated structure, the entire shock absorber needs to be replaced, which is not ideal. This design adopts a separate and detachable connecting plate, which is convenient and simple to replace later (the connecting plate can be easily removed by removing the countersunk screws on the connecting plate) and low cost. Another advantage is that two connecting plate structures, internal threaded holes and external threaded columns, can be selected according to the installation method. Figure 3 , 4 As shown; three shock-absorbing springs are used, and the shock-absorbing springs are evenly distributed in three directions, so the force is more evenly distributed.
[0037] The elastic force generated by the shock absorber varies depending on the specifications of the spring, so shock absorbers with different elastic forces can be selected according to the weight of the equipment.
[0038] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
