[0002] During the construction of existing engineering projects, it is often necessary to lay pipelines for transporting tap water, fire water, natural gas, etc. If these pipelines are directly fixed on the wall top, they are prone to falling during an earthquake, thus triggering safety accidents. Therefore, the brackets for pipeline fixing need to have good seismic resistance.
[0003] Most of the existing seismic brackets are directly fixedly connected to the wall top through bolts to support pipelines or air ducts. However, if the pipelines or air ducts vibrate for a long time, it may cause the bolts of the seismic brackets to loosen and fall off.
[0004] Therefore, it is necessary to provide a seismic bracket with a quick bite connection structure to solve the above technical problems. Content of the Utility Model

However, if the pipelines or air ducts vibrate for a long time, it may cause the bolts of the seismic brackets to loosen and fall off.
[0006] To solve the above technical problems, the utility model provides a seismic bracket with a quick bite connection structure, which includes a top plate. Both sides of the bottom end of the top plate are fixedly provided with fixing seats, and the number of the fixing seats is two. The inner parts of one ends of the two fixing seats are both threadedly connected with long column bolts. The inside of the two long column bolts both penetrate through a positioning shaft. The outside of the positioning shaft is rotatably installed with a connecting seat through a bearing.

DETAILED DESCRIPTION
[0018] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.
[0019] Please refer to Figure 1-Figure 3 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of a seismic-resistant bracket with a quick-engagement connection structure provided by the utility model; Figure 2 for Figure 1 A schematic diagram of the structure of the bottom end of the top plate is shown; Figure 3 for Figure 2Schematic diagram of the internal structure of the fixed seat shown. An anti-seismic bracket with a quick bite connection structure includes a top plate 1. Fixed seats 2 are fixed on both sides of the bottom end of the top plate 1, and the number of fixed seats 2 is two. Long column bolts 7 are threadedly connected inside one end of each of the two fixed seats 2. A positioning shaft 8 penetrates through the inside of each of the two long column bolts 7. A connecting seat 6 is rotatably installed outside the positioning shaft 8 through a bearing. A clamping seat 4 is fixed at one end of the connecting seat 6 and located inside the fixed seat 2. The shape of the clamping seat 4 is "L". A long groove 5 is opened inside the clamping seat 4. A fixed shaft 3 is fixed inside the fixed seat 2 and located inside the long groove 5.
[0020] The user fixes the top plate 1 to the wall top through bolts, and then fixes the positioning frame 9 to the lower surface of the top plate 1 through bolts. Then the user rotates the long column bolt 7 forward to move the position of the clamping seat 4 forward until the clamping seat 4 is located inside the positioning frame 9. Then the long column bolt 7 is rotated in reverse so that the clamping seat 4 can be snapped into the inside of the groove 10. Then the long column bolt 7 is rotated in reverse again, and the positioning frame 9 is secondarily positioned by the pulling force of the two clamping seats 4, which can prevent the positioning frame 9 from falling due to the loosening of the bolts connecting it to the top plate 1 caused by vibration.
[0021] When the long column bolt 7 rotates forward, the long column bolt 7 extends into the fixed seat 2. The long column bolt 7 is rotatably connected to the connecting seat 6 through the positioning shaft 8. The clamping seat 4 can slide forward through the long groove 5 and tilt downward, so that one end of the clamping seat 4 can move into the positioning frame 9.
[0022] A positioning frame 9 is fixed to the bottom end of the top plate 1 and located in the middle position between the two fixed seats 2 through bolts. The shape of the positioning frame 9 is "U". Grooves 10 are opened on both inner walls of the positioning frame 9.
[0023] The grooves 10 on both sides of the positioning frame 9 can be snap-connected with one end of the clamping seat 4.
[0024] Positioning columns 11 are fixed at the four corners of the bottom end of the positioning frame 9, and the number of positioning columns 11 is four. Limit disks 13 are fixed at the bottom ends of the four positioning columns 11. A placement plate 12 is slidably installed outside the four positioning columns 11.
[0025] After the positioning frame 9 is fixed, the user can place the air duct or pipeline above the placement plate 12.
[0026] Springs 14 are sleeved outside the four positioning columns 11 and located below the placement plate 12 and above the limit disks 13.
[0027] When the pipeline or air duct vibrates, the springs 14 at the bottom end of the placement plate 12 can perform shock absorption treatment on it.
[0028] The working principle of the seismic support with a quick snap connection structure provided by the utility model is as follows:
[0029] The user fixes the top plate 1 to the top of the wall by bolts, and then fixes the positioning frame 9 to the lower surface of the top plate 1 by bolts. Then, the user moves the position of the holder 4 forward by rotating the long column bolts 7 forward until the holder 4 is located inside the positioning frame 9, and then reverses the long column bolts 7 so that the holder 4 can be engaged into the inside of the groove 10. Then, the long column bolts 7 are reversed and the positioning frame 9 is repositioned by the pulling force of the two holders 4. This can prevent the positioning frame 9 from vibrating and causing the bolts connecting the top plate 1 to be sent to the positioning frame 9, causing the positioning frame 9 to fall off. After the positioning frame 9 is fixed, the user can place the air duct or pipe on top of the placement plate 12, and install the pipe or air duct through the placement plate 12. When the pipe or air duct vibrates, the spring 14 at the bottom of the placement plate 12 can reduce the shock.
[0030] Compared with the related art, the seismic bracket with a quick snap connection structure provided by the utility model has the following beneficial effects:
[0031] The user fixes the top plate 1 to the top of the wall with bolts, and then fixes the positioning frame 9 to the lower surface of the top plate 1 with bolts. Then, the user moves the position of the holder 4 forward by rotating the long column bolts 7 forward until the holder 4 is located inside the positioning frame 9, and then reverses the long column bolts 7 so that the holder 4 can be engaged into the inside of the groove 10. Then, the long column bolts 7 are reversed and the positioning frame 9 is repositioned by the pulling force of the two holders 4. This can prevent the positioning frame 9 from vibrating and causing the bolts connecting the positioning frame 9 to the top plate 1 to be sent to the positioning frame 9, causing it to fall off.
