[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] Embodiments of the present utility model:

[0023] like Figure 1-6 As shown, an adjustable lightweight anti-seismic bracket includes an outer sleeve 1 and an inner sleeve 4. The top end of the inner sleeve 4 is slidably arranged inside the outer sleeve 1. The bottom of the inner sleeve 4 is provided with a baffle 42. The inner sleeve 4 is sleeved with a first spring 41. A first narrow groove 10 is opened on the outer peripheral wall of the outer sleeve 1. A ring 2 is provided on the outside or sliding sleeve of the outer sleeve 1. A support plate 20 is provided on the ring 2. The suspension end of the support plate 20 is penetrated by the first narrow groove 10 and is located inside the outer sleeve 1. The outer wall of the outer sleeve 1 is provided with a ring 2. An adjusting ring 3 is screwed on the top, the top of the adjusting ring 3 and the bottom end of the circular ring 2 abut against each other, the top of the first spring 41 abuts the bottom side of the baffle 42, and the bottom end of the first spring 41 abuts the support plate 20; a second narrow groove 40 is provided on the outer peripheral wall of the inner sleeve 4, and a connecting plate 11 is provided on the bottom end face of the outer sleeve 1, and the connecting plate 11 is penetrated by the second narrow groove 40, and a damping rod 8 is provided inside the inner sleeve 4, the top of the damping rod 8 is connected to the internal top wall of the inner sleeve 4, and the bottom end of the damping rod 8 is connected to the connecting plate 11.

[0024] The top of the first spring 41 abuts the baffle 42 on the inner sleeve 4, and the bottom of the first spring 41 abuts the ring 2 set on the outer sleeve 1, thereby realizing elastic cooperation between the outer sleeve 1 and the inner sleeve 4. In addition, the adjusting ring 3 supporting the ring 2 can rotate relatively. When the adjusting ring 3 rotates upward, the adjusting ring 3 abuts the ring 2, and the supporting plate 20 on the ring 2 moves upward. The first spring 41 is compressed, making the telescopic sliding between the outer sleeve 1 and the inner sleeve 4 more difficult. When the adjusting ring 3 rotates downward, the adjusting ring 3 no longer abuts the ring 2, and the compression amount of the first spring 41 is reduced, making the elastic sliding between the outer sleeve 1 and the inner sleeve 4 easier. During use, the adjustment of the adjusting ring 3 can be determined according to the weight of the object fixed by the anti-seismic bracket. If it is heavier, the adjusting ring 3 can be adjusted upward to ensure the stability of the connected object.

[0025] In addition, in order to avoid frequent movement between the outer sleeve 1 and the inner sleeve 4 under the action of the first spring 41 alone, a damping rod 8 is provided inside the inner sleeve 4. The top of the damping rod 8 is connected to the inner sleeve 4, and the bottom is connected to the outer sleeve 1 to achieve a balance between the two and ensure the stability of the cooperation between the two.

[0026] Under the cooperation relationship between the first spring 41 and the damping rod 8 as well as the outer sleeve 1 and the inner sleeve 4, the entire seismic bracket can effectively prevent the connected object from being affected by vibration, and the entire device only achieves buffering and shock absorption through the cooperation relationship between the outer sleeve 1 and the inner sleeve 4, which is very convenient for both installation and subsequent maintenance.

[0027] In some further embodiments, the number of the first slots 10 is four, and the four first slots 10 are circumferentially spaced apart; the number of the support plates 20 is four, and the four support plates 20 are circumferentially spaced apart.

[0028] There are four first slots 10 and four support plates 20 , and each support plate 20 is located in a corresponding first slot 10 , thereby providing uniform support for the bottom of the first spring 41 and preventing the first spring 41 from twisting and failing.

[0029] In some further embodiments, a first mounting plate 6 and a second mounting plate 7 are further included, the first mounting plate 6 is elastically connected to the second mounting plate 7, a first spherical groove is provided on the side of the first mounting plate 6 facing the second mounting plate 7, and a second spherical groove is provided on the side of the second mounting plate 7 facing the first mounting plate 6, a connecting hole is provided at the bottom of the second spherical groove, a ball head rod 64 is provided on the top outside of the outer sleeve 1, the ball head end of the ball head rod 64 is located between the first mounting plate 6 and the second mounting plate 7, and the rod end of the ball head rod 64 is connected to the outer sleeve 1 through the connecting hole.

[0030] The first mounting plate 6 is used to connect to the top of the wall. The first mounting plate 6 and the second mounting plate 7 elastically press the ball rod 64, allowing the ball rod 64 to rotate to a certain extent under the action of external force. Therefore, when the vibration is too large, the entire outer sleeve 1 can rock at a certain angle relative to the first mounting plate 6 and the second mounting plate 7, thereby achieving the effect of "unloading force".

[0031] In some further embodiments, a bolt 60 is provided on the first mounting plate 6, and one end of the bolt 60 passes through the second mounting plate 7 and is threaded with a nut 61. A second spring 62 is provided on the bolt 60, and one end of the second spring 62 abuts the second mounting plate 7, and the other end of the second spring 62 abuts one end surface of the nut 61.

[0032] The elastic connection between the first mounting plate 6 and the second mounting plate 7 is achieved by bolts 60, nuts 61 and second springs 62. Preferably, four groups of bolts 60, nuts 61 and second springs 62 are provided and installed in a 2x2 arrangement in a square pattern to ensure uniform force on the ball head of the ball head rod 64.

[0033] In some further embodiments, a mounting hole 63 is provided at the bottom of the first spherical groove, and the mounting hole 63 is set through the first mounting plate 6. A third spring 630 is provided in the mounting hole 63. A fixing column is screwed to one end of the mounting hole 63 away from the second mounting plate 7. One end of the third spring 630 abuts against the end face of the fixing column, and the other end of the third spring 630 abuts against the ball head of the ball head rod 64.

[0034] When the fixing column is rotated toward the inside of the mounting hole 63, the fixing column presses against the third spring 630, causing the third spring 630 to be compressed, thereby increasing the force acting on the ball head of the ball head rod 64; when the fixing column is rotated outward, the third spring 630 is released, and the force acting on the ball head is reduced. The actual situation can be adjusted.

[0035] In some further embodiments, a clamp 5 is provided at the bottom end of the inner sleeve 4; the clamp 5 is used to fix the installed pipeline.

[0036] Working principle:

[0037] By rotating the adjusting ring 3 , the compression degree of the first spring 41 can be adjusted, thereby adjusting the elasticity of the entire anti-seismic bracket to adapt to different installation environments.

[0038] Obviously, the embodiments described are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art are within the scope of protection of the present invention.
