The utility model is characterized in that the clamping plate and the spring in the supporting plate are squeezed outward by the pipeline, the clamping plate moves in the movable groove, and the clamping plate is pressed against the outer wall of the pipeline by the elastic force of the compressed spring, so that the clamping plate can fit pipelines of different sizes, thereby improving applicability, and the position of the connecting plate at the end of the movable rod is limited by the limiting block and the limiting groove that penetrate the connecting plate and the movable rod, so that the angle adjustment of the connecting plate at the end of the movable rod is more stable, and the inclined state of the connecting plate is more stable.

[0004] The above patent fixes the water pipe by setting an elastic connecting component on one side of the arc plate, thereby achieving the purpose of fixing water pipes of different diameters. However, since the curvature of the arc plate used is fixed, when the water pipe is not of a specific diameter, the contact area between the water pipe with a fixed curvature and the arc plate is small, resulting in a poor fixing effect.

[0005] For this purpose, an anti-seismic bracket for a pipeline is proposed. Utility Model Content

[0006] The purpose of the utility model is to solve the problem of poor applicability of traditional earthquake-resistant brackets, and to provide an earthquake-resistant bracket for pipelines.

[0009] Furthermore, the elastic connecting member includes an outer rod, an inner rod and a spring, the outer rod is fixed to the U-shaped mounting seat, one end of the inner rod is fixed to the first plate body, and the other end passes through the outer rod and extends to the inside to contact the spring.

[0010] Furthermore, the connecting parts are bolts.

[0011] Furthermore, the support arm includes an outer rod and an inner rod, the inner rod is sleeved in the inner cavity of the outer rod, the outer rod is partially broken to form a first part and a second part, and a bearing is rotatably connected between the first part and the second part, the first part and the second part are fixed by a fixing rod, and the inner wall of the bearing is provided with an internal thread, which is engaged with the external thread of the outer wall of the inner rod.

[0012] Furthermore, a limit slider is provided at the end of the inner rod, and the limit slider is slidably arranged in a groove on the inner wall of the outer rod.

[0013] Furthermore, a rubber layer is provided on the outer surface of the bearing.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. By forming an arc-shaped plate by splicing and using elastic connectors, water pipes of different diameters can be fixed. At the same time, compared with the arc-shaped plate with a fixed curvature, the spliced ​​arc-shaped plate has more contact points with the water pipe, and is accompanied by a clamping force, so that the water pipe can be better fixed.

[0016] 2. The internal thread is driven to move by the rotation of the bearing, so that the movement of the inner rod can be adjusted with high accuracy and without the need for tools, so the adjustment method is relatively simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1-4As shown, a seismic support for a pipeline comprises two relatively arranged U-shaped mounting seats 1, a water pipe contact piece 3 for fixing the pipeline and a support arm 5 with adjustable length, the two U-shaped mounting seats 1 are detachably fixed by a connecting component 2, one end of the support arm 5 is movably connected to the U-shaped mounting seat 1 located above, and the other end is movably connected to a mounting plate 6, the water pipe contact piece 3 comprises a first plate body 31, a second plate body 32, a hinge 33 and an elastic connecting piece, the second plate body 32 is two in number and is relatively arranged with the first plate body 31 as the center, and forms an arc with the first plate body 31 bending toward the U-shaped mounting seat 1, the second plate body 32 is rotatably connected to the water pipe contact piece 3 near one end of the first plate body 31 through the hinge 33, and the first plate body 31 and the second plate body 32 are connected to the U-shaped mounting seat 1 by an elastic connecting piece 4.

[0027] In this embodiment, after the support arm 5 is fixed, only the U-shaped mounting seat 1 below needs to be fixed. At this time, the pipe is aligned between the two U-shaped mounting seats 1 and the two U-shaped mounting seats 1 are fixed by bolts. Since the first plate body 31 and the second plate body 32 are fixed to the U-shaped mounting seat 1 by the U-shaped mounting seat 1, when the diameter of the pipe is larger than the diameter originally formed by the first plate body 31 and the second plate body 32, when the pipe is placed in the fixed area formed by the two water pipe contact members 3, the pipe will squeeze the first plate body 31 and move backward. Since the second plate body 32 and the first plate body 31 were previously hinged to the first plate body 31 by the hinge 33, as the first plate body 31 moves downward, the second plate body 32 will rotate and stick to the surface of the water pipe. At the same time, with the action of the support arm 5 at the bottom of the first plate body 31, it is not only possible to quickly install water pipes of different diameters, but also has a better fixing effect relative to the curved plate with a fixed shape.

[0028] Specifically, the support arm 5 includes an outer rod 51 and an inner rod 52, the inner rod 52 is sleeved in the inner cavity of the outer rod 51, the outer rod 51 is partially broken to form a first part and a second part, and a bearing 53 is rotatably connected between the first part and the second part, and the first part and the second part are fixed by a fixing rod 54, and the inner wall of the bearing 53 is provided with an internal thread, which is engaged with the external thread on the outer wall of the inner rod 52.

[0029] In this embodiment, since the bearing 53 and the outer rod 51 are rotatably connected, as the bearing 53 rotates, the bearing 53 is equivalent to a nut, so the internal thread inside the bearing 53 can also rotate, and the inner rod 52 engaged with the inner wall of the bearing 53 can also continuously move outward or inward along the axial direction of the outer rod 51 as the bearing 53 rotates, thereby adjusting the overall length of the bracket arm 5, making the use of the bracket arm 5 more flexible and having higher adjustment accuracy than the bolt spacing adjustment method.

[0030] Specifically, a limiting slider 55 is disposed at the end of the inner rod 52 , and the limiting slider 55 is slidably disposed in a groove on the inner wall of the outer rod 51 .

[0031] In this embodiment, the limit slider 55 can prevent the inner rod 52 and the bearing 53 from rotating at the same time, resulting in the length being unable to be adjusted.

[0032] In summary: after the bracket arm 5 is fixed, only the U-shaped mounting seat 1 below needs to be fixed. At this time, align the pipe between the two U-shaped mounting seats 1 and fix the two U-shaped mounting seats 1 with bolts. Since the first plate body 31 and the second plate body 32 are fixed to the U-shaped mounting seat 1 through the U-shaped mounting seat 1, when the diameter of the pipe is larger than the diameter originally formed by the first plate body 31 and the second plate body 32, when the pipe is placed in the fixed area formed by the two water pipe contact members 3, the pipe will squeeze the first plate body 31 and move backward. Since the second plate body 32 and the first plate body 31 were previously hinged to the first plate body 31 through the hinge 33, as the first plate body 31 moves downward, the second plate body 32 will be 32 rotates and sticks to the surface of the water pipe. Since the bearing 53 and the outer rod 51 are rotatably connected, as the bearing 53 rotates, the bearing 53 is equivalent to a nut, so the internal thread inside the bearing 53 can also rotate, and the inner rod 52 engaged with the inner wall of the bearing 53 can also continuously move outward or inward along the axial direction of the outer rod 51 as the bearing 53 rotates, so that the overall length of the bracket arm 5 can be adjusted. The elastic connecting member includes an outer rod, an inner rod and a spring. The outer rod is fixed to the U-shaped mounting seat 1, one end of the inner rod is fixed to the first plate body 31, and the other end passes through the outer rod and extends to the inside to contact the spring. The connecting component 2 adopts a bolt.
