[0032] As Figures 6-8 The pressing plate adjusting structure 6 includes an upper pressing plate 601 located above the lifting moving plate 4, the lower surface of the upper pressing plate 601 is provided with a plurality of auxiliary springs 602, the lower surface of the auxiliary springs 602 is attached to the upper surface of the lifting moving plate 4, the upper surface of the upper pressing plate 601 is provided with an upper recess 603, the upper recess 603 is provided with a screw rod seat 604, the screw rod seat 604 is provided with a screw rod 605, the center of the cover plate 2 is provided with a center threaded hole 201, the screw rod 605 is engaged in the center threaded hole 201, and a screw rod pressing plate 606 is sleeved on the screw rod 605, and the screw rod pressing plate 606 is installed on the upper pressing plate 601.

[0033] In order to observe the distance between the upper pressing plate 601 and the lifting moving plate 4, further, the left and right sides of the upper pressing plate 601 and the lifting moving plate 4 are respectively provided with side threaded holes 7, and the left and right sides of the outside of the casing 1 are respectively provided with positioning seats 8, the positioning seats 8 are connected into the side threaded holes 7 through bolts.

[0034] In order to facilitate the installation of the positioning seat 8, further, the positioning seat 8 includes a seat body 801 in T-shaped structure, the seat body 801 is provided with a connecting through hole 802, the connecting through hole 802 penetrates from the left side to the right side of the seat body 801, and the left side of the connecting through hole 802 is further provided with a counterbore 803.

[0035] In order to prevent dust from entering the spring support hanger, further, dust fluffs 102 are arranged in the rectangular recess 101.

[0036] In order to facilitate the installation of the utility model, further, the upper surface of the cover plate 2 is provided with a plurality of lifting lugs 202.

[0037] In order to be able to fix the pipeline, further, the bottom of the moving rod 5 is provided with a mounting seat 9.

[0038] In actual use, the elasticity of the main spring in the spring support hanger will decrease after long-term use, which will cause the amplitude of the up-down displacement of the lifting moving plate 4 to increase during lifting, resulting in poor damping effect.

[0039] In the present patent, the entire device is installed at a set position through the lifting lug 202, the upper end of the main spring 3 in the present patent is fixedly connected with the lifting moving plate 4, and the lower end of the main spring 3 is fixedly connected with the shell 1. When the lifting moving plate 4 is lifted, the lifting moving plate 4 pulls or compresses the main spring 3, so that the lifting moving plate 4 drives the pipeline to play a damping role.

[0040] When installing, the device in the present patent is installed at a set position through the lifting lug 202, and the pipeline to be damped is fixed to the mounting seat 9. At this time, the pipeline to be damped will pull down the moving rod 5 and the lifting moving plate 4 due to the action of gravity. At this time, the lifting moving plate 4 will compress the main spring 3 and stabilize to a set position. At this time, the adjusting screw 605 is adjusted, the upper pressing plate 601 is moved by the screw 605, the auxiliary spring 602 on the upper pressing plate 601 is pressed to the upper surface of the lifting moving plate 4, then the positioning seat 8 is respectively installed to the side edges of the lifting moving plate 4 and the upper pressing plate 601, and the position of the positioning seat 8 is drawn on the shell.

[0041] When using, when the pipeline vibrates, the pipeline first drives the lifting moving plate 4 to move up and down through the moving rod 5, and the lifting moving plate 4 and the main spring 3 are fixed together. In this way, the vibration of the pipeline can be offset by the elasticity of the spring of the main spring 3.

[0042] In the present patent, when the vibration is relatively strong, the amplitude of the up-down movement of the lifting moving plate 4 will be relatively large. When the amplitude of the upward movement of the lifting moving plate 4 is large, the lifting moving plate 4 will impact the auxiliary spring 602. In this way, the amplitude of the movement of the lifting moving plate 4 can be reduced by the elasticity of the auxiliary spring 602, thereby solving the problem that in the prior art, the movable plate will always rigidly impact the pressing block, and after long-term use, the movable plate or the pressing block will be damaged or deformed, thereby affecting subsequent use.

[0043] When the main spring 3 is used for a long time, the elasticity of the main spring 3 will decrease, which will cause the distance between the upper surface of the lifting moving plate 4 and the auxiliary spring 602 to increase, resulting in poor damping effect of the present patent.

[0044] In view of the above situation, in the prior art, the adjustment can only be made by opening the shell, and the distance between the pressing block and the movable plate cannot be observed from the outside. The shell also needs to be opened to observe, which causes the work to be relatively cumbersome and the operation to be relatively troublesome.

[0045] In the patent, a plurality of positioning seats 8 are arranged on the outer side of the shell 1, and the positioning seats 8 are fixed to the lifting moving plate 4 and the upper pressing plate 601 respectively. When the distance between the lifting moving plate 4 and the upper pressing plate 601 becomes larger, the distance between the positioning seats 8 can be observed. When the distance between the positioning seats 8 is within the set range, it indicates that the elasticity of the main spring 3 is weakened but still within the set range. At this time, the adjusting screw 605 is adjusted, and the auxiliary spring 602 on the upper pressing plate 601 is moved above the positioning seat 8 through the adjusting screw 605, so as to continue to play the role of shock absorption.

[0046] When the distance between the positioning seats 8 is greater than the set range, it indicates that the elasticity of the main spring 3 cannot meet the set requirements, and the main spring 3 needs to be replaced at this time.

[0047] Through the above method, the distance between the lifting moving plate 4 and the upper pressing plate 601 can be adjusted from the outside, the elastic distance in the patent is adjusted, the problem that the shell needs to be opened to adjust the pressing block in the prior art is solved, and the distance between the pressing block and the movable plate cannot be observed from the outside, and the shell also needs to be opened to observe, which leads to the problem that the work is more complicated and the operation is more troublesome.

[0048] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
