Description

Technical Field

[0001] This utility model belongs to the field of seismic bracing technology, specifically relating to a seismic bracing with a long service life. Background Technology

[0002] Seismic bracing is a type of component or device that limits the displacement of auxiliary electromechanical engineering facilities, controls the vibration of the facilities, and transfers the load to the load-bearing structure. Currently, most seismic bracing on the market is suspended. In order to extend the service life of seismic bracing, existing seismic bracing is usually subjected to anti-corrosion treatment, such as hot-dip galvanizing, electro-galvanizing, and spraying, which can effectively extend the service life of the bracing and prevent corrosion and oxidation.

[0003] Chinese Patent CN218599022U discloses a seismic support with a rust-proof structure, comprising: a support frame, a connecting block, a rotating mechanism, a support rod, and a T-slot. The connecting block is installed on the inner side of the support frame, the rotating mechanism is installed on both sides of the support frame, and the support rod is connected to the outer side of the rotating mechanism. The T-slot is formed through the interior of the support frame and the connecting block, and a T-block is connected inside the T-slot. A limiting plate is connected between two T-blocks, and foam is adhered to the outer side of the limiting plate. A threaded rod is installed on the outer side of the T-block away from the limiting plate, and a nut is connected to the outer side of the threaded rod. The outer surfaces of the support frame, the connecting block, and the support rod are all coated with a rust-proof paint layer.

[0004] Regarding the aforementioned related technologies, the inventors have discovered at least the following problems: the seismic brace can be installed on ducts of different widths by adjusting the position of the limiting plates. However, in order to accommodate larger ducts, the maximum distance between the two limiting plates needs to be set relatively large, which results in a very large width for the entire seismic brace. Although narrower ducts can be fixed by adjusting the distance between the two limiting plates, the width of the seismic brace cannot be adjusted. When fixing narrower ducts in narrower spaces, the large width of the seismic brace can easily restrict installation. Utility Model Content

[0005] The purpose of this invention is to provide a seismic bracing system with a long service life to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a long-service-life seismic brace, comprising two symmetrically distributed L-shaped hangers, a connecting pipe slidably connected between the two L-shaped hangers, and a limiting component disposed inside the L-shaped hangers. The two L-shaped hangers are slidably inserted into both ends of the connecting pipe. A bidirectional screw is rotatably installed inside the connecting pipe. Both ends of the bidirectional screw extend into the interior of the two L-shaped hangers and are threadedly connected to the L-shaped hangers. A driving component for driving the bidirectional screw to rotate is disposed in the middle of the connecting pipe.

[0007] The limiting assembly includes a vertical screw rod rotatably mounted inside the L-shaped hanger, with a first knob fixedly connected to the upper end of the vertical screw rod, and a T-shaped limiting plate threaded onto the vertical screw rod.

[0008] In a preferred embodiment, the driving component includes a worm gear rotatably mounted inside a connecting pipe, a second knob fixedly connected to the lower end of the worm gear, and a worm wheel meshing with the worm gear fixedly connected to the middle of the bidirectional screw.

[0009] In a preferred embodiment, the L-shaped hanger has a first sliding groove on both sides, and the L-shaped hanger is slidably connected to the connecting pipe through the first sliding groove.

[0010] In a preferred embodiment, a second sliding groove is provided on the inner side of the L-shaped hanger, and the T-shaped limiting plate is slidably connected to the L-shaped hanger through the second sliding groove.

[0011] In a preferred embodiment, a first rubber pad is fixedly connected to the top surface of the connecting pipe.

[0012] In a preferred embodiment, a second rubber pad is fixedly connected to one side of the T-shaped limiting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This long-life seismic bracing system, through the cooperation of L-shaped hangers and connecting pipes, allows for the operation of a drive mechanism when installing ducts of different widths. The drive mechanism rotates a bidirectional screw, which in turn causes two L-shaped hangers to slide relative to or opposite to each other along the ends of the connecting pipe. This adjusts the distance between the two L-shaped hangers, changing the width of the seismic bracing system. Consequently, it can adapt to different installation spaces when installing ducts of varying widths, reducing installation limitations.

[0015] This long-life seismic bracing system, through the setting of the limiting components, ensures that after the width of the seismic bracing is adjusted appropriately, the distance between the two T-shaped limiting plates matches the width of the air duct. After the seismic bracing is installed, the air duct is first placed on the connecting pipe. Then, the first knob can be rotated, causing the first knob to drive the vertical screw to rotate, causing the vertical screw to drive the T-shaped limiting plates to descend, pressing the T-shaped limiting plates against both sides of the air duct, thus limiting and fixing both sides of the air duct. It is easy to operate and can be used to install air ducts of different heights. Attached Figure Description

[0020] The present invention will be further described below with reference to the embodiments.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please see Figure 1-3This utility model provides a long-service-life seismic support, comprising two symmetrically distributed L-shaped hangers 1, a connecting pipe 2 slidably connected between the two L-shaped hangers 1, and a limiting component 3 disposed inside the L-shaped hangers 1. The two L-shaped hangers 1 are slidably inserted into both ends of the connecting pipe 2. A bidirectional screw 21 is rotatably installed inside the connecting pipe 2. The bidirectional screw 21 is horizontally arranged along the length of the connecting pipe 2, and both ends of the bidirectional screw 21 extend into the interior of the two L-shaped hangers 1 and are threadedly connected to the L-shaped hangers 1. The middle of the connecting pipe 2... The unit is equipped with a drive component 22 for driving the bidirectional screw 21 to rotate. Through the cooperation of the L-shaped hanger 1 and the connecting pipe 2, the drive component 22 can be operated when installing ducts of different widths. The drive component 22 drives the bidirectional screw 21 to rotate, and the bidirectional screw 21 drives the two L-shaped hangers 1 to slide relative to or opposite to each other along the two ends of the connecting pipe 2. This allows the spacing between the two L-shaped hangers 1 to be adjusted, changing the width of the seismic support. Thus, when installing ducts of different widths, it can adapt to different installation spaces and reduce the limitations during installation.

[0023] Specifically, the driving component 22 includes a worm gear 221 rotatably installed inside the connecting pipe 2. A second knob 222 is fixedly connected to the lower end of the worm gear 221, and a worm wheel 223 that meshes with the worm gear 221 is fixedly connected to the middle part of the bidirectional screw 21. By setting the driving component 22, the second knob 222 can be rotated during operation, which drives the worm gear 221 to rotate, causing the worm gear 221 to drive the worm wheel 223 to rotate, and causing the worm wheel 223 to drive the bidirectional screw 21 to rotate.

[0024] The L-shaped hanger 1 has a first sliding groove 11 on both sides. The L-shaped hanger 1 is slidably connected to the connecting pipe 2 through the first sliding groove 11. The first sliding groove 11 can guide the L-shaped hanger 1 and the connecting pipe 2 to slide.

[0025] Specifically, the limiting component 3 includes a vertical screw 31 rotatably installed inside the L-shaped hanger 1. A first knob 32 is fixedly connected to the upper end of the vertical screw 31, and a T-shaped limiting plate 33 is threaded onto the vertical screw 31. Through the setting of the limiting component 3, when the width of the seismic support is adjusted appropriately, the distance between the two T-shaped limiting plates 33 matches the width of the air duct. After the seismic support is installed, the air duct is first placed on the connecting pipe 2. Then, the first knob 32 can be rotated to drive the vertical screw 31 to rotate, causing the vertical screw 31 to drive the T-shaped limiting plate 33 to descend, so that the T-shaped limiting plate 33 is pressed against both sides of the air duct, limiting and fixing both sides of the air duct. The operation is convenient and can install air ducts of different heights.

[0026] The L-shaped hanger 1 has a second sliding groove 12 on its inner side. The T-shaped limiting plate 33 is slidably connected to the L-shaped hanger 1 through the second sliding groove 12. The second sliding groove 12 can guide the T-shaped limiting plate 33 to slide.

[0027] Furthermore, a first rubber pad 23 is fixedly connected to the top surface of the connecting pipe 2, and a second rubber pad 34 is fixedly connected to one side of the T-shaped limiting plate 33. With the setting of the first rubber pad 23 and the second rubber pad 34, when the air duct is installed, the first rubber pad 23 abuts against the connecting pipe 2 and the air duct, and the second rubber pad 34 abuts between the T-shaped limiting plate 33 and the air duct, thereby playing a shock-absorbing and buffering role for the air duct.

[0028] The surfaces of the L-shaped hanger 1, connecting pipe 2, and limiting component 3 are all coated with anti-corrosion coatings, which can extend the service life of the seismic bracing.

[0029] The working principle and usage process of this utility model are as follows: First, when installing ducts of different widths, the second knob 222 can be rotated, which drives the worm gear 221 to rotate, which in turn drives the worm wheel 223 to rotate, which in turn drives the bidirectional screw 21 to rotate. The bidirectional screw 21 drives the two L-shaped hangers 1 to slide relative to or opposite to each other along the two ends of the connecting pipe 2, thereby adjusting the distance between the two L-shaped hangers 1 and changing the width of the seismic support. When the width of the seismic support is properly adjusted, the distance between the two T-shaped limiting plates 33 matches the width of the duct. After the seismic support is installed, the duct is first placed on the connecting pipe 2. Then, the first knob 32 can be rotated, which drives the vertical screw 31 to rotate, which in turn drives the T-shaped limiting plates 33 to descend, pressing the T-shaped limiting plates 33 against both sides of the duct, thus limiting and fixing both sides of the duct. This operation is convenient and can be used to install ducts of different heights.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
