[0034] Furthermore, the vertical guide micro-buffer assembly includes a T-shaped guide rod 8 fixedly connected to the bottom inner wall of the L-shaped support plate 4, and the L-shaped carrier plate 2 is slidably mounted on multiple T-shaped guide rods 8, wherein the bottom inner wall of the L-shaped carrier plate 2 is provided with multiple vertical guide holes that are respectively slidably mounted on the outer sides of the corresponding T-shaped guide rods 8, which play the role of guiding the vertical sliding of the L-shaped carrier plate 2, and multiple buffer springs 9 are fixedly connected between the bottom inner wall of the L-shaped support plate 4 and the bottom of the L-shaped carrier plate 2, and the buffer springs 9 are movably mounted on the corresponding T-shaped guide rods 8, and the compression stroke of the buffer springs 9 is 0.5-1cm; the T-shaped guide rod 8 and the buffer spring 9 are arranged to cooperate, and when the clamped gas pipeline undergoes a hard up-and-down shock, the L-shaped carrier plate 2 will be driven to vibrate up and down on multiple T-shaped guide rods 8, and the buffer springs 9 will be compressed or released, and the elastic force of the buffer springs 9 and the shock-absorbing rubber block 3 is used to buffer and unload the hard shock force.

[0035] The third T-shaped screw 7 is fixedly connected to the bottom of the fixed plate 1, and the third T-shaped screw 7 is rotatably installed between the inner walls of the two sides of the rectangular hole 5. Two third bearings are fixedly connected between the inner walls of the two sides of the rectangular hole 5. The inner side of the inner ring of the third bearing is fixedly connected to the outer side of the third T-shaped screw 7, which plays the effect of rotatably installing the third T-shaped screw 7. The rectangular plate 6 is threadedly sleeved on the third T-shaped screw 7, and the bottom of the rectangular plate 6 is provided with a thread groove threadedly connected to the third T-shaped screw 7. The threaded connection relationship between the two is utilized to facilitate the up-and-down displacement of the third T-shaped screw 7 when the third T-shaped screw 7 is rotated. The arranged rectangular plate 6 and the third T-shaped screw 7 cooperate with each other, and the third T-shaped screw 7 is rotated and moved up and down in the rectangular plate 6 by rotating it. The up-and-down movement of the third T-shaped screw 7 drives the L-shaped support plate 4 to move up and down, and the L-shaped support plate 4 drives the L-shaped carrier plate 2 to move up and down to adjust the height of the suspension support.

[0036] The method of using this embodiment is as follows: the personnel install and fix the fixing plate 1 in advance through the external fixing bolts, and when adjusting the support height of the L-shaped carrier plate 2 according to the gas pipeline suspension support height requirement, the third T-shaped screw rod 7 is rotated forward to make it rotate in the thread groove of the rectangular plate 6 and move downward. At this time, the third T-shaped screw rod 7 drives the L-shaped support plate 4 to slide downward on the rectangular plate 6, and the L-shaped support plate 4 drives the L-shaped carrier plate 2 to move downward through the buffer spring 9. After moving downward to a suitable height, the third T-shaped screw rod 7 is stopped from rotating, so that the support height can be flexibly adjusted according to the suspension support requirements;

[0037] The gas pipeline is placed in the concave part at the top of the shock-absorbing rubber block 3. The shock-absorbing rubber block 3 itself is flexible and can directly fit with the outer bottom thereof when being squeezed downward by the gas pipeline. At this time, the first T-shaped screw 12 is rotated forward to make it rotate in the first threaded hole on the L-shaped carrier plate 2 and move downward. At this time, the first T-shaped screw 12 drives the box-shaped plate 11 to move downward, and the box-shaped plate 11 drives the rectangular tube 10 to slide downward on the L-shaped carrier plate 2. At the same time, the box-shaped plate 11 drives the arc-shaped elastic pressing plate 13 to move downward through the second T-shaped screw 14, the U-shaped rod 15 and the extrusion rod 16 in sequence. The arc-shaped elastic pressing plate 13 drives the anti-slip rubber downward to press and prevent the gas pipeline from falling off. By using the L-shaped carrier plate 2 to support the bottom and cooperating with the upper pressing and preventing falling off, the gas pipeline can be stably supported and prevented from falling off at the bottom after being fixed, thereby improving the anti-falling stability during suspension support.

[0038] When the gas pipeline has different specifications and its outer curvature is inconsistent with the curvature of the arc-shaped elastic pressure plate 13, resulting in inability to stably fit and press, the second T-shaped screw 14 is rotated forward to drive the U-shaped rod 15 downward alone, and the U-shaped rod 15 drives the two extrusion rods 16 to squeeze the two sides of the arc-shaped elastic pressure plate 13 downward. Under the extrusion force, the two sides of the arc-shaped elastic pressure plate 13 are bent inward, changing the bending curvature until the arc-shaped elastic pressure plate 13 is squeezed and fits tightly with the outer side of the top of the gas pipeline, so that it is convenient to adjust the bending curvature of the arc-shaped elastic pressure plate 13 according to gas pipelines of different specifications, further improve the stability of the gas pipeline from being pressed and anti-detached, and use the adjustable bending curvature to facilitate the stable fixation of gas pipelines of different specifications, thereby improving applicability;

[0039] During suspension protection, when the gas pipeline is subjected to hard vibration upward and downward, the shock-absorbing rubber block 3 can be squeezed and driven to vibrate upward and downward through the shock-absorbing rubber block 3. The L-shaped carrier plate 2 vibrates upward and downward on multiple T-shaped guide rods 8, and the buffer spring 9 is compressed or released. The elastic force of the buffer spring 9 and the shock-absorbing rubber block 3 cooperate to effectively buffer and unload the hard vibration force, thereby improving the buffering effect when the gas pipeline is subjected to hard vibration upward and downward, thereby improving the safety of use.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents.
