Description

Technical Field

[0001] This utility model relates to the field of bracket technology, specifically a bracket with a size fine-tuning structure. Background Technology

[0002] Seismic bracing is an important component that ensures the stability and safety of buildings under earthquake action. It is mainly used to support and fix cable trays, fire pipes, ventilation ducts, etc. in buildings to reduce the swaying and displacement of cable trays and pipes during earthquakes, thereby protecting the building structure and the safety of people. However, existing bracing systems still have certain defects in use.

[0003] In the existing technology, brackets are mainly used for building water supply and drainage, fire protection, heating, ventilation and other facilities. The brackets are usually installed on the indoor ceiling. The brackets can support cable trays and pipes, and can also play a certain role in seismic resistance. During use, the cable trays are usually located below the pipes. If the height of the cable trays is high, the size between the pipe support rod and the cable tray support rod needs to be adjusted. The traditional adjustment method requires adjusting both ends of the pipe support rod separately. This adjustment method is relatively troublesome and time-consuming. Utility Model Content

[0004] The purpose of this invention is to provide a bracket with a size adjustment structure to solve the problem of inconvenient size adjustment of brackets currently on the market, as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bracket with a size adjustment structure, comprising: a fixed rod, a diagonal brace, a cable tray support rod, a pipe support rod, and a pipe fixing ring. The outer side of the fixed rod is connected to the diagonal brace. The bottom ends of the two fixed rods are connected to the cable tray support rod. A pipe support rod is positioned above the cable tray support rod. A pipe fixing ring is installed on the surface of the pipe support rod. A connecting rod is welded between the two fixed rods. A fixing block is installed at the bottom of the connecting rod. An annular groove is formed inside the fixing block. A rotating disk is rotatably connected inside the annular groove. A connecting column is connected to the bottom of the rotating disk. A threaded ring is welded to the bottom of the two connecting columns. A threaded rod is welded to the surface of the pipe support rod. Guide blocks are welded to the inner sides of the two fixed rods near the pipe support rod. A guide groove matching the size of the pipe support rod is formed inside the guide block.

[0006] Preferably, the pipe support rod and the guide block form a sliding structure through a guide groove.

[0007] Preferably, the threaded ring and the threaded rod form a threaded structure, and the threaded rod and the fixed block form an insertion structure.

[0008] Preferably, the cable tray support rod has a through hole inside, and a fixing column is welded to the inner side of the cable tray support rod near the through hole.

[0009] Preferably, the bottom of the cable tray support rod is connected to a mounting block, and the interior of the mounting block is connected to a bidirectional lead screw via a bearing.

[0010] Preferably, the outer sides of the bidirectional lead screw and the fixed column are connected to a moving block, the top of the moving block is connected to a limiting block, and the opposing sides of the two limiting blocks are connected to a buffer protrusion.

[0011] Preferably, the movable block and the fixed column form a sliding structure, and the movable block and the bidirectional lead screw form a threaded structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When the threaded ring rotates, it can drive the connecting column to rotate. When the connecting column rotates, it can drive the rotating disk to rotate. When the rotating disk rotates, it can rotate inside the fixed block through the annular groove. When the two sets of limiting blocks move towards each other to the two sides of the cable tray, the two sets of limiting blocks can clamp and limit the cable tray. At the same time, the buffer protrusion will generate extrusion deformation and press against the two sides of the cable tray to prevent the cable tray from sliding. The two sets of limiting blocks can quickly clamp and fix the cable tray on the cable tray support rod, thereby preventing the cable tray from shaking and shifting, and making it convenient for personnel to quickly install and fix the cable tray later.

[0013] 1. Support brackets are widely used in earthquake-resistant building construction. During use, adjusting the dimensions between the pipe support rod and the cable tray support rod can be cumbersome. When the threaded ring rotates, it drives the connecting column to rotate, which in turn drives the rotating disk. The rotating disk rotates within the fixed block through the annular groove. When the threaded rod moves, it moves the pipe support rod, and when the pipe support rod slides, it raises the pipe fixing ring. When the pipe support rod reaches the designated position, the rotation of the threaded ring stops. At this point, the dimensions between the pipe support rod and the cable tray support rod can be adjusted accordingly. By rotating the threaded ring, the dimensions between the pipe support rod and the cable tray support rod can be adjusted, allowing the pipe support rod to be quickly positioned according to the dimensions of the cable tray on the support rod.

[0014] 2. During use, the cable tray needs to be placed on the cable tray support rod first. If the cable tray is placed directly on the support rod, it is prone to shaking, which is not conducive to subsequent fixed installation. When the double-sided screw rotates, it can drive two sets of moving blocks to slide closer to each other. When the moving blocks slide, they can drive the limit blocks to move. When the limit blocks move, they can slide through the fixed column. When the two sets of limit blocks move towards each other to the two sides of the cable tray, the two sets of limit blocks can clamp and limit the cable tray. At the same time, the buffer protrusion will generate compression deformation and press against the two sides of the cable tray to prevent the cable tray from sliding. The two sets of limit blocks can quickly clamp and fix the cable tray on the support rod, thereby preventing the cable tray from shaking and shifting, and making it convenient for personnel to quickly install and fix the cable tray later.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3It is understood that this utility model provides a technical solution: a bracket with a size fine-tuning structure, including: a fixed rod 1, a diagonal brace 2, a cable tray support rod 3, a pipe support rod 4, and a pipe fixing ring 5. The diagonal brace 2 is connected to the outer side of the fixed rod 1, and the bottom ends of the two fixed rods 1 are connected to the cable tray support rod 3. The pipe support rod 4 is arranged above the cable tray support rod 3, and the pipe fixing ring 5 is installed on the surface of the pipe support rod 4. A connecting rod 6 is welded between the two fixed rods 1, and a fixing block 7 is installed at the bottom of the connecting rod 6. An annular groove 8 is formed inside the fixing block 7. The internal rotating connection is a rotating disk 9, the bottom of the rotating disk 9 is connected to a connecting column 10, the bottom of the two connecting columns 10 are welded together with a threaded ring 11, the surface of the pipe support rod 4 is welded with a threaded rod 12, the two fixed rods 1 are welded with guide blocks 13 near the inner side of the pipe support rod 4, the guide block 13 has a guide groove 14 that matches the size of the pipe support rod 4, the pipe support rod 4 and the guide block 13 form a sliding structure through the guide groove 14, the threaded ring 11 and the threaded rod 12 form a threaded structure, and the threaded rod 12 and the fixed block 7 form an insertion structure.

[0022] In practical implementation, the support system is widely used in building seismic resistance. During use, adjusting the dimensions between the pipe support rod 4 and the cable tray support rod 3 is quite troublesome. When it is necessary to increase the dimensions between the pipe support rod 4 and the cable tray support rod 3, the threaded ring 11 can be rotated clockwise. When the threaded ring 11 rotates, it can drive the connecting column 10 to rotate. When the connecting column 10 rotates, it can drive the rotating disk 9 to rotate. When the rotating disk 9 rotates, it can rotate inside the fixed block 7 through the annular groove 8. When the threaded ring 11 rotates, it can drive the threaded rod 12 to slide threadedly towards the connecting rod 6. When the threaded rod 12 moves, it can drive the pipe support rod 4 to move. When the pipe support rod 4 moves, it can slide through the guide groove 14 and the guide block 13. When the pipe support rod 4 slides, it can drive the pipe fixing ring 5 to rise. When the pipe support rod 4 rises to the designated position, the rotation of the threaded ring 11 is stopped. At this time, the dimensions between the pipe support rod 4 and the cable tray support rod 3 can be adjusted accordingly.

[0023] See Figures 1-3 It can be seen that the dimensions between the pipe support rod 4 and the cable tray support rod 3 can be adjusted by rotating the threaded ring 11, so that the position of the pipe support rod 4 can be quickly adjusted according to the dimensions of the cable tray on the cable tray support rod 3.

[0024] See Figure 1 and Figure 4It is known that a through hole 15 is opened through the inside of the cable tray support rod 3. A fixing column 16 is welded to the inner side of the cable tray support rod 3 near the through hole 15. An installation block 17 is connected to the bottom of the cable tray support rod 3. A double-acting screw 18 is connected to the inside of the installation block 17 through a bearing. A moving block 19 is connected to the outer side of the double-acting screw 18 and the fixing column 16. A limit block 20 is connected to the top of the moving block 19. A buffer protrusion 21 is connected to the opposite side of the two limit blocks 20. A sliding structure is formed between the moving block 19 and the fixing column 16. A threaded structure is formed between the moving block 19 and the double-acting screw 18. The buffer protrusions 21 are evenly distributed on the outer surface of the limit block 20.

[0025] In practical implementation, during the use of the bracket, the cable tray needs to be placed on the cable tray support rod 3 first. When the cable tray is placed directly on the cable tray support rod 3, it is easy to shake, which is not conducive to the later fixed installation. The double-acting screw 18 can be rotated in the forward direction. When the double-acting screw 18 rotates, it can drive the two sets of moving blocks 19 to slide closer to each other. When the moving blocks 19 slide, they can drive the limit blocks 20 to move. When the limit blocks 20 move, they can slide through the fixed column 16. When the limit blocks 20 move, they can drive the buffer protrusion 21 to move. The buffer protrusion 21 is made of rubber. When the two sets of limit blocks 20 move towards each other to the two sides of the cable tray, the two sets of limit blocks 20 can clamp and limit the cable tray. At the same time, the buffer protrusion 21 will generate compression deformation and press against the two sides of the cable tray to prevent the cable tray from sliding.

[0026] See Figure 1 and Figure 4 It can be seen that the cable tray on the cable tray support rod 3 can be quickly clamped and fixed by the two sets of limit blocks 20, thereby preventing the cable tray from shaking and shifting, and making it convenient for personnel to quickly install and fix the cable tray later.

[0027] In summary, when using this bracket with a micro-adjustment structure, the rotation of the threaded ring 11 drives the connecting column 10 to rotate, and the rotation of the connecting column 10 drives the rotating disk 9 to rotate. When the pipe support rod 4 rises to the designated position, the rotation of the threaded ring 11 stops. At this time, the dimensions between the pipe support rod 4 and the cable tray support rod 3 can be adjusted accordingly. By rotating the threaded ring 11, the dimensions between the pipe support rod 4 and the cable tray support rod 3 can be adjusted, so that the pipe support rod 4 can quickly adjust its position according to the dimensions of the cable tray on the cable tray support rod 3. The two sets of limit blocks 20 can quickly clamp and fix the cable tray on the cable tray support rod 3, thereby preventing the cable tray from shaking or shifting, and facilitating the quick installation and fixation of the cable tray by personnel later.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
