[0002] In fire protection engineering, the stability of fire protection pipelines is directly related to the reliability of the fire safety system. Existing fire protection pipeline fixing brackets are mostly rigid structures with fixed clamping dimensions, requiring manual tightening for installation.

[0003] A search revealed a fire pipe fixing bracket for fire protection engineering, with publication number CN112555514B. The bracket includes two mounting plates mounted on the ceiling, each with a vertical rod underneath. A clamping device for holding the pipe is provided between the two vertical rods. A disassembly assembly is provided within each mounting plate, allowing for convenient disassembly of the vertical rods and mounting plates. This application facilitates the disassembly of the fire pipe fixing bracket.

[0004] However, the clamping device of this patent requires manual twisting for each adjustment. It would be more convenient to adjust it by gravity. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a fire pipe fixing bracket for fire protection engineering. Through the elastic adjustment structure of the pipe limiting component, it can automatically adapt to fire pipes of different diameters. The movable rod inside the movable sleeve can be adjusted in length. With the elastic pressure of the spring, the second positioning ball on the crank arm can swing adaptively with the pipe size, realizing dynamic clamping of the pipe diameter. After one adjustment, it can be used again for the next connection of the same pipe diameter without further adjustment, eliminating the drawback of having to tighten it every time.

[0006] A fire-fighting pipe fixing bracket for fire protection engineering includes a fixing pipe, characterized in that the upper side of one end of a fixing rod is fixedly connected to the lower side of the fixing pipe, the fixing rod is connected to a pipe limiting component, and the pipe limiting component is used to limit the pipe.

[0007] The pipe limiting assembly includes a movable sleeve that passes through the other end of the fixed rod. An adjustable movable rod is installed inside the movable sleeve. A first positioning ball is fixedly connected to the upper end of the movable rod. Extending arms are fixedly connected to both sides of the other end of the fixed rod. A sliding rod is fixedly connected to the extending arms. The sliding rod is slidably fitted within a sliding groove, which is located on one side of a crank arm. A lug is rotatably connected to one end of the crank arm. The lug fixes the lower end of the movable sleeve. A spring passes through the movable sleeve. The fixed rod is fixed to the upper end of the spring, and the lug is fixed to the lower end of the spring. A second positioning ball is installed at the other end of the crank arm.

[0008] Furthermore, the second positioning ball is spherical and fixedly connected to the other end of the crank arm, the crank arm is V-shaped and the two crank arms are symmetrically arranged.

[0009] Furthermore, the second positioning ball includes a bolt and a ball, the bolt being screwed to the other end of the crank arm, and the end of the bolt being fixedly connected to the ball.

[0010] Furthermore, a number of uniformly arranged sleeves are fixedly installed on the fixed tube, and the sleeves are screwed to the top rod. A third positioning ball is fixedly installed at one end of the top rod inside the fixed tube.

[0011] Furthermore, the surface of the second positioning ball is a rubber layer.

[0012] Furthermore, the surface of the sphere is a rubber layer.

[0013] Furthermore, the surfaces of the first and third positioning balls are made of rubber.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are:

[0015] (1) Through the elastic adjustment structure of the pipe limiting component, it can automatically adapt to fire pipes of different diameters. The movable rod inside the movable sleeve can be adjusted in length. With the elastic pressure of the spring, the second positioning ball on the crank arm can swing adaptively with the pipe size, realizing dynamic clamping of the pipe diameter. After one adjustment, the connection of the same pipe diameter can continue to be used without adjustment, eliminating the drawback of needing to screw every time.

[0016] (2) The second positioning ball of the bolt-fitted second positioning ball structure can also adjust the extension length through the bolt to further adapt to non-standard pipe diameters. The three-point fit structure of the first positioning ball (bottom) and the second positioning ball (both sides), combined with the continuous elastic pressure of the spring, can ensure the stable support of the pipeline during installation.

[0017] (3) The surfaces of the first positioning ball, the second positioning ball (and the ball body) and the third positioning ball are all provided with a rubber layer, which can prevent metal parts from directly contacting the pipe and reduce the wear of the outer wall of the pipe.

[0023] The following is in conjunction with the appendix Figure 1-3 The present invention will be further described in terms of the embodiments and implementation methods.

[0024] A fire pipe fixing bracket for fire protection engineering includes a fixing pipe 3, the lower side of which is fixedly connected to the upper side of one end of a fixing rod 4, and the fixing rod 4 is connected to a pipe limiting component, which is used to limit the pipe.

[0025] The pipe limiting assembly includes a movable sleeve 8, which passes through the other end of the fixed rod 4. An adjustable movable rod 12 is installed inside the movable sleeve 8. The upper end of the movable rod 12 is fixedly connected to a first positioning ball 13. Extending arms 11 are fixedly connected to both sides of the other end of the fixed rod 4. A sliding rod 6 is fixedly connected to the extending arm 11. The sliding rod 6 is slidably fitted within a sliding groove 7, which is located on one side of a crank arm 5. A lug 9 is rotatably connected to one end of the crank arm 5. The lug 9 fixes the lower end of the movable sleeve 8. The movable sleeve 8 passes through a spring 10. The upper end of the spring 10 fixes the fixed rod 4, and the lower end of the spring 10 fixes the lug 9. A second positioning ball 14 is installed at the other end of the crank arm 5.

[0026] In this embodiment, the combination structure of the fixed pipe 3, the fixed rod 4, and the pipe limiting component utilizes elastic adjustment and multi-directional positioning to achieve stable limiting of the fire-fighting pipe. The movable rod 12 inside the movable sleeve 8 is adjustable in length and, in conjunction with the first positioning ball 13, positions the bottom of the pipe. The movable sleeve 8 can be screwed onto the movable rod 12, allowing for continued use of the same pipe diameter after one adjustment, eliminating the need for tightening for each operation. The sliding rod 6 on the extended arm 11 slides within the sliding groove 7 of the crank arm 5, while the crank arm 5 is rotatably connected to the movable sleeve 8 via the lug 9, allowing the crank arm 5 to adaptively swing according to the pipe size. The spring 10 provides elastic pressure, ensuring that the second positioning ball 14 on the crank arm 5 always fits against the side of the pipe. Finally, through the three-point cooperation of the first positioning ball 13 (bottom) and the second positioning ball 14 (both sides), the pipe is clamped and limited, achieving adaptive fixing of fire-fighting pipes of different diameters and improving fixing stability.

[0027] In the initial state of the spring 10, the two second positioning balls 14 are in a close proximity.

[0028] Furthermore, the second positioning ball 14 is spherical and fixedly connected to the other end of the crank arm 5, the crank arm 5 is V-shaped and the two crank arms 5 are symmetrically arranged.

[0029] In this embodiment, the second positioning ball 14 is spherical, which can increase the contact area with the pipe and reduce local pressure. The crank arm 5 is V-shaped and symmetrically arranged. The symmetrical structure ensures that the force on both sides of the pipe is balanced. The V-shaped design adapts to the arc surface of the pipe, improves the fit, and adapts to more common diameter circular fire-fighting pipes.

[0030] Furthermore, the second positioning ball 14 includes a bolt 16 and a ball 161, wherein the bolt 16 is screwed to the other end of the crank arm 5, and the end of the bolt 16 is fixedly connected to the ball 161.

[0031] In another embodiment, the second positioning ball 14 is designed as a structure in which the ball 161 is fixedly connected by a bolt 16. The bolt 16 is screwed to the crank arm 5. The extension length of the ball 161 can be adjusted by rotating the bolt 16, so as to achieve fine adjustment of the position of the second positioning ball 14. The clamping distance can be adjusted according to the actual diameter of the pipe (especially non-standard pipe diameter), thereby enhancing the versatility and adaptability of the fixing frame.

[0032] Furthermore, a plurality of uniformly arranged sleeves 2 are fixedly installed on the fixed tube 3, and the sleeves 2 are screwed to the top rod 1. A third positioning ball 15 is fixedly installed at one end of the top rod 1 inside the fixed tube 3.

[0033] In this embodiment, a sleeve 2 with a uniformly arranged circumference is added to the fixing tube 3. The extension length of the push rod 1 inside the sleeve 2 is adjusted by screw connection. The third positioning ball 15 at the end is used to fit the fixed part inside the fixing tube 3. Through the cooperation of the third positioning ball 15 and the push rod 1, a stable connection between the fixing tube 3 and the fixed part is achieved, avoiding loosening between the fixing tube 3 and the fixed part. At the same time, the uniformly arranged circumference ensures that the fixing tube 3 is subjected to balanced force, enhancing the installation stability of the entire fixing frame.

[0034] Furthermore, the surface of the second positioning ball 14 is a rubber layer.

[0035] Furthermore, the surface of the sphere 161 is a rubber layer.

[0036] Furthermore, the surfaces of the first positioning ball 13 and the third positioning ball 15 are rubber layers.

[0037] The method of using this utility model is as follows: the fixed pipe 3 is sleeved on the end of the pipe, the top rod 1 inside the sleeve 2 which is evenly arranged around the circumference of the fixed pipe 3 is rotated so that the third positioning ball 15 at the end of the top rod 1 is tightly attached to the outer wall of the pipe. The pipe is held in place by the top rod 1 and the third positioning ball 15, so that the relative position of the fixed pipe 3 and the pipe is fixed, and the end of the pipe completely passes through the fixed pipe. The end of the pipe is placed between the fixed pipe 3 and the crank arm 5, and then used to erect another suspended fire pipe connected to the end of the pipe.

[0038] If the fire-fighting pipe to be connected is a non-standard diameter pipe, the clamping range of the second positioning ball 14 can be initially set by rotating the bolt 16 at the end of the crank arm 5 (for the structure of the bolt 16 and the ball 161) and adjusting the extension length of the ball 161. After the adjustment is completed, the extension length of the ball 161 will not need to be adjusted again when supporting and limiting the same pipe next time, saving time and avoiding repetitive work.

[0039] The fire-fighting pipe is placed on the first positioning ball 13. The weight of the pipe will press down on the movable rod 12, causing the movable sleeve 8 to move downwards. At this time, the spring 10 undergoes elastic deformation, and the lug 9 moves downwards with the movable sleeve 8, causing the crank arm 5 to rotate. When the crank arm 5 rotates, the slide groove 7 on one side slides along the slide rod 6 on the extended arm 11, causing the second positioning ball 14 at the other end of the crank arm 5 to move closer to both sides of the pipe until the second positioning ball 14 is tightly attached to the outer wall of the pipe. Under the elastic rebound force of the spring 10, the first positioning ball 13 and the second positioning ball 14 form a three-point clamping force, which stably fixes the pipe and ensures that the ends of the two pipes are in contact. Then, the pipe is connected and fixed. After installation, the third positioning ball 15 is released, and the two crank arms 5 are pulled so that the second positioning ball 14 no longer presses against the pipe. The device can then be pulled out along the connected pipe.

[0040] The above-disclosed embodiments are merely specific examples of this utility model. However, this utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
