Description

Technical Field

[0001] This utility model belongs to the field of seismic bracing technology, and specifically relates to a quick-connecting structure for seismic bracing. Background Technology

[0002] Seismic bracing is a structural reinforcement technology used for buildings and equipment to enhance their ability to resist natural disasters such as earthquakes.

[0003] Currently, Chinese utility model patent CN210623306U discloses a quick-connect structure for seismic bracing. Existing seismic bracing systems typically use metal pipe clamps welded to the bottom of elevated pipelines. One end of the clamp is hinged to allow the pipe to be inserted, while the other end is bolted in. However, this connection method is cumbersome, as bolts require tools to tighten or loosen, making it impossible to manually install and fix the pipe into the clamp. Furthermore, the height of the elevated pipeline can generally only be adjusted during installation. After the pipeline is fixed, the seismic bracing cannot be directly adjusted. If the heights of the two ends of the pipeline are inconsistent, one end must be removed from the seismic bracing and reinstalled, which is inconvenient and has low practicality. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-connecting structure for seismic bracing, which has the advantage of enabling the metal pipe buckles at the bottom of the seismic bracing to quickly engage and connect, thereby locking and fixing the pipe, and also facilitating the height adjustment of the seismic bracing.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a quick-connecting structure for an anti-seismic bracket, comprising a connecting plate, a first buckle plate welded to the bottom of the connecting plate, a second buckle plate hinged to the bottom of the first buckle plate, a slot provided on the side of the bottom of the first buckle plate away from the hinge point of the second buckle plate, a sliding block slidably connected to one side of the top of the second buckle plate, an L-shaped locking block welded to the top of the sliding block and engaging with the slot, a spring fixedly connected to the second buckle plate at one end of the sliding block, and a sliding rod slidably connected to the second buckle plate at the end of the sliding block away from the spring.

[0006] By employing the above technical solution, the spring force pushes the L-shaped locking block at the top of the sliding block, engaging it within the slot and preventing the second locking plate from rotating downwards. This allows the first and second locking plates to quickly engage, enabling the overhead pipe connection to be installed at the bottom of the seismic brace, improving installation efficiency. After removing the positioning bolt from the seismic brace, the extension bracket can be pulled upwards within the brace for adjustment. Once both ends of the pipe are adjusted to the same height, the extension bracket is re-locked using the positioning bolt and locking nut. This facilitates height adjustment of the seismic brace, improving its practicality.

[0007] The present invention is further configured such that: seismic bracing is welded to both sides of the top of the connecting plate; a sliding groove is provided on the side of the two seismic bracing that is far apart from each other; a positioning bolt that is slidably connected to the sliding groove is provided inside the seismic bracing; an extension bracket is slidably connected inside the seismic bracing; an insertion hole that is slidably connected to the positioning bolt is provided inside the extension bracket; and a locking nut that is engaged with the seismic bracing is threaded onto the surface of the positioning bolt near the sliding groove.

[0008] By adopting the above technical solution, after the positioning bolt is pulled out from inside the seismic support, the extension support can be pulled to slide upward inside the seismic support for adjustment, thereby facilitating the height adjustment of the seismic support.

[0009] The present invention is further configured such that anti-slip pads are adhered to the sides of the first buckle plate and the second buckle plate that are close to each other.

[0010] By adopting the above technical solution, the friction of the pipe after it is installed inside the first and second buckles is increased, thereby improving the connection stability.

[0011] The present invention is further configured such that a pressing block that is slidably connected to the second buckle plate is welded to the side of the sliding rod away from the sliding block.

[0012] By adopting the above technical solution, it is easy to push the sliding rod to slide inside the second buckle by pressing the pressing block, thereby pushing the sliding block to move.

[0013] The present invention is further configured such that: a trapezoidal groove is provided on the side of the top of the L-shaped card block away from the spring, which is slidably connected to the first buckle plate.

[0014] Using the above technical solution, the trapezoidal groove can be used to bring the second buckle plate close to the first buckle plate, and the first buckle plate can push the L-shaped locking block to slide automatically to the side of the spring.

[0015] The present invention is further configured such that threaded rods are welded to the top of both of the extension brackets.

[0016] The above technical solution facilitates the installation of the extension bracket on the ceiling of the building, thereby enabling the seismic bracing to be bolted and fixed.

[0017] The present invention is further configured such that the surfaces of the seismic brace and the extension brace are coated with a corrosion-resistant coating.

[0018] By adopting the above technical solution, the corrosive effect of moisture on the surface of the seismic bracing and extension bracing is reduced, thereby avoiding the difficulty of the extension bracing sliding inside the seismic bracing due to rust, and ensuring smooth sliding.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. By utilizing the spring force to push the L-shaped locking block at the top of the sliding block, the L-shaped locking block is engaged inside the locking groove, preventing the second snap plate from rotating downwards. This allows the first and second snap plates to quickly engage together, enabling the overhead pipe connection to be installed at the bottom of the seismic support, improving installation efficiency;

[0021] 2. By pulling the positioning bolt out of the seismic bracing, the extension bracket can be pulled upwards inside the seismic bracing for adjustment. After adjusting both ends of the pipe to the same height, the extension bracket can be re-locked and secured using the positioning bolt and locking nut. This facilitates height adjustment of the seismic bracing and improves its practicality. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Example 1:

[0029] refer to Figure 1 , Figure 2 , Figure 3 A quick-connecting structure for seismic bracing includes a connecting plate 1. A first snap plate 2 is welded to the bottom of the connecting plate 1. A second snap plate 3 is hinged to the bottom of the first snap plate 2. A slot 4 is formed on the bottom side of the first snap plate 2 away from the hinge point of the second snap plate 3. A sliding block 5 is slidably connected to the top side of the second snap plate 3. An L-shaped locking block 7 that engages with the slot 4 is welded to the top of the sliding block 5. A spring 6 that is fixedly connected to the second snap plate 3 is bolted to one end of the sliding block 5. A sliding rod 8 that is slidably connected to the second snap plate 3 is welded to the end of the sliding block 5 away from the spring 6. By using the elastic force of the spring 6 to push the L-shaped locking block 7 on the top of the sliding block 5, the L-shaped locking block 7 is engaged inside the slot 4, preventing the second snap plate 3 from rotating downwards. This allows the first snap plate 2 and the second snap plate 3 to quickly engage together, enabling overhead pipe connections to be installed at the bottom of the seismic bracing, improving installation efficiency.

[0030] refer to Figure 1 , Figure 3 Anti-slip pads 15 are adhered to the sides of the first snap plate 2 and the second snap plate 3 that are close to each other. This increases the friction after the pipe is installed inside the first snap plate 2 and the second snap plate 3, improving the connection stability.

[0031] refer to Figure 3 A pressing block 16, which is slidably connected to the second snap plate 3, is welded to the side of the sliding rod 8 away from the sliding block 5. This allows the sliding rod 8 to slide inside the second snap plate 3 by pressing the pressing block 16, thereby pushing the sliding block 5 to move.

[0032] refer to Figure 3 The top of the L-shaped locking block 7, away from the spring 6, has a trapezoidal groove 17 that is slidably connected to the first buckle plate 2. By using the trapezoidal groove 17 to bring the second buckle plate 3 close to the first buckle plate 2, the first buckle plate 2 can push the L-shaped locking block 7 to slide automatically toward the side of the spring 6.

[0033] Brief description of usage: Open the second snap plate 3 by rotating it, allowing the pipe to be inserted between the first snap plate 2 and the second snap plate 3. Then close the second snap plate 3 to the bottom of the first snap plate 2, while simultaneously pushing the sliding rod 8 to slide inwards into the second snap plate 3. This causes the sliding rod 8 to drive the sliding block 5 to overcome the elastic force of the spring 6, thereby causing the L-shaped locking block 7 to slide, thus fitting the second snap plate 3 against the bottom of the first snap plate 2. Afterwards, release the sliding rod 8, using the elastic force of the spring 6 to push the L-shaped locking block 7 at the top of the sliding block 5, thus locking the L-shaped locking block 7 into the slot 4, preventing the second snap plate 3 from rotating downwards. This locks the first snap plate 2 and the second snap plate 3 together, allowing the pipe to be connected and installed at the bottom of the seismic support.

[0034] Example 2:

[0035] refer to Figure 1 , Figure 2 , Figure 4 A quick-connecting structure for seismic bracing is disclosed. Seismic bracing 9 is welded to both sides of the top of the connecting plate 1. Each seismic bracing 9 has a sliding groove 11 on its opposite side. A positioning bolt 12, slidably connected to the sliding groove 11, is inserted through the interior of each seismic bracing 9. An extension bracing 10 is slidably connected inside the seismic bracing 9. An insertion hole 13, slidably connected to the positioning bolt 12, is opened inside the extension bracing 10. A locking nut 14, engaging with the seismic bracing 9, is threaded onto the surface of the positioning bolt 12 near the sliding groove 11. By pulling the positioning bolt 12 out of the seismic bracing 9, the extension bracing 10 can be pulled upwards within the seismic bracing 9 for adjustment. After adjusting both ends of the pipe to the same height, the extension bracing 10 is re-locked and fixed using the positioning bolt 12 and the locking nut 14. This facilitates height adjustment of the seismic bracing and improves its practicality.

[0036] refer to Figure 1 , Figure 2 Both extension brackets 10 have threaded rods 18 welded to their tops. This facilitates the installation of the extension brackets 10 on the ceiling of the building, thereby securing them to the seismic bracing system.

[0037] refer to Figure 1 , Figure 2 Both the seismic bracing 9 and the extension bracing 10 are coated with a rust-resistant coating. This reduces the corrosive effect of moisture on the surfaces of the seismic bracing 9 and the extension bracing 10, thereby preventing rust from hindering the extension bracing 10 from sliding inside the seismic bracing 9 and ensuring smooth sliding.

[0038] Brief description of the usage process: After the pipe connection is installed to the bottom of the seismic brace, the positioning bolt 12 is slid out of the seismic brace 9 by rotating the loosening locking nut 14, allowing it to slide inside the slide groove 11. Then, the extension bracket 10 is pulled up and slid upward inside the seismic brace 9 for adjustment. Afterward, the positioning bolt 12 is slid back into the seismic brace 9, allowing the seismic brace 9 to pass through the insertion hole 13 and slide forward inside the slide groove 11, thereby passing the other end of the positioning bolt 12 through the seismic brace 9. Finally, the locking nut 14 is rotated again to lock it onto the surface of the positioning bolt 12.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
