Description

Technical Field

[0001] This utility model relates to the field of support technology, and in particular to an end support for fire sprinkler pipes. Background Technology

[0002] Fire sprinkler pipe end supports are key components supporting the end of the sprinkler pipe. They are mainly used to fix the position of the pipe end, preventing the pipe from shifting or deforming due to its own weight, water flow impact, or external vibration, and ensuring the overall stability of the sprinkler pipe installation. They can work with the pipeline system to maintain a reasonable installation posture, ensuring that the sprinkler heads can be correctly aimed at the protected area in the event of a fire and spray water smoothly to extinguish the fire. At the same time, they reduce the impact of pipe end shaking on adjacent pipes or other fire protection facilities, providing basic support for the reliable operation of the fire sprinkler system. They are an indispensable auxiliary component in the installation of fire pipelines.

[0003] The clamping and fixing mechanism of the end bracket for fire sprinkler pipes is a core component to ensure the stability of pipe installation. Existing mechanisms often have problems such as insufficient clamping adaptability and limited fixing strength. Some structures are fixed only by a single clamp or strap, which is prone to gaps due to differences in pipe outer diameter and is easily loosened by water flow impact and vibration. It is difficult to meet the fastening requirements under different working conditions. Therefore, there is a need for an end bracket for fire sprinkler pipes. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide an end bracket for fire sprinkler pipes, which can solve the problems of poor adaptability, low adjustment accuracy and easy loosening due to vibration of existing clamping mechanisms, resulting in pipe positioning deviation, insufficient clamping force and inability to ensure stable operation of fire sprinkler pipes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an end bracket for a fire sprinkler pipe, comprising a fixed base and a tightening and fixing mechanism. The tightening and fixing mechanism includes a side plate, a clamping plate base, a lower clamping plate, a fastening component, a fastening screw, a threaded cylinder, and a knob. The side plate is fixedly connected to the surface of the fixed base. The clamping plate base is L-shaped and is fixedly connected to the bottom of the side plate. The threaded cylinder is fixedly connected to the surface of the clamping plate base. The fastening screw is threadedly connected to the inner wall of the threaded cylinder. The fastening component is rotatably connected to the top of the fastening screw. The lower clamping plate is fixedly connected to the clamping plate base via a bracket. The fastening component is slidably connected to the inside of the lower clamping plate. The lower end of the fastening screw extends out of the bottom of the clamping plate base. The knob is fixedly connected to the bottom of the fastening screw. The outer surface of the knob is provided with anti-slip texture.

[0006] Preferably, a support frame is fixedly connected to the bottom of the fixed base, a movable frame is slidably connected to the surface of the support frame, an upper clamping plate is fixedly connected to the bottom of the movable frame, the upper clamping plate is located above the lower clamping plate, and the curvature of the upper clamping plate is exactly the same as that of the lower clamping plate.

[0007] Preferably, a motor bracket is fixedly connected to the bottom of the fixed base, a motor is fixedly connected to the bottom of the motor bracket, and a gear A is fixedly connected to the output end of the motor, with gear A rotatably connected to the bottom of the fixed base.

[0008] Preferably, a threaded rod is rotatably connected to the bottom of the fixed base, and a gear B is fixedly sleeved on the outer surface of the threaded rod, with gear B meshing with gear A.

[0009] Preferably, the outer surface of the threaded rod is threaded with a slider, the surface of the slider is fixedly connected to a connecting bracket, and the end of the connecting bracket away from the slider is fixedly connected to the movable frame.

[0010] Preferably, the top two sides of the fixing base are provided with multiple screw holes, and the fixing base is bolted to the ceiling or the ground through the screw holes.

[0011] Preferably, the fastening component may be a fastener with a smooth surface.

[0012] Preferably, the fastening assembly may also be a fastener with equidistant grooves on its surface.

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

[0014] 1. The fire sprinkler pipe end bracket and tightening mechanism form a stable support base through the side plate and L-shaped clamp base. The threaded engagement of the threaded cylinder and the fastening screw achieves linear transmission, which can precisely control the lifting stroke of the fastening component and effectively adapt to the gap compensation between the pipe and the clamp. The sliding connection between the lower clamp and the fastening component ensures the stability of the adjustment process. The anti-slip texture on the outer surface of the knob improves the ease of operation. The tightening operation can be completed without additional tools. Moreover, the fastening component can be selected with a smooth or grooved structure according to the characteristics of the pipe surface to enhance the fit with the pipe and significantly improve the clamping force and stability.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0025] Please see Figure 1-4 This utility model provides a technical solution: an end bracket for a fire sprinkler pipe, wherein:

[0026] Multiple screw holes 9 are provided on both sides of the top of the fixed base 1. The fixed base 1 is bolted to the ceiling or ground through the screw holes 9. This kind of connection can securely install the entire end bracket in the designated position and provide a reliable foundation for the subsequent work of various components. The commonly used metal material ensures sufficient load-bearing strength.

[0027] The bottom of the fixed base 1 is fixedly connected to the support frame 2, and the surface of the support frame 2 is slidably connected to the movable frame 3. The bottom of the movable frame 3 is fixedly connected to the upper clamping plate 4. The support frame 2 provides a sliding track for the movable frame 3. The movable frame 3 drives the upper clamping plate 4 to move, so that the upper clamping plate 4 and the lower clamping plate 7 can cooperate to perform preliminary positioning of the pipeline.

[0028] A side plate 5 is fixedly connected to the surface of the fixed base 1. An L-shaped clamp base 6 is fixedly connected to the bottom of the side plate 5. A lower clamp 7 is fixedly connected to the clamp base 6 through a bracket. The side plate 5 provides support for the clamp base 6, and the clamp base 6 provides an installation carrier for the lower clamp 7. The lower clamp 7 has the same curvature as the upper clamp 4 to ensure the fit of the pipe.

[0029] A threaded cylinder 18 is fixedly connected to the surface of the clamping base 6. A fastening screw 17 is threadedly connected to the inner wall of the threaded cylinder 18. A fastening component 8 is rotatably connected to the top of the fastening screw 17. The fastening component 8 is slidably connected inside the lower clamping plate 7. The threaded engagement between the threaded cylinder 18 and the fastening screw 17 can adjust the lifting and lowering of the fastening component 8 to achieve clamping of the pipe.

[0030] The lower end of the fastening screw 17 extends out of the bottom of the clamp base 6, and a knob 19 is fixedly connected to the bottom of the fastening screw 17. The outer surface of the knob 19 is provided with anti-slip texture. Rotating the knob 19 can drive the fastening screw 17 to rotate. The anti-slip texture can increase the friction of the hand, making it easier for the operator to operate with less effort and improving the convenience of adjustment.

[0031] A motor bracket 10 is fixedly connected to the bottom of the fixed base 1, and a motor 11 is fixedly connected to the bottom of the motor bracket 10. A gear A12 is fixedly connected to the output end of the motor 11. The motor bracket 10 provides a stable installation position for the motor 11. After the motor 11 is started, it can drive the gear A12 to rotate, providing a power source for subsequent transmission.

[0032] A threaded rod 14 is rotatably connected to the bottom of the fixed base 1. A gear B13 is fixedly sleeved on the outer surface of the threaded rod 14. The gear B13 meshes with the gear A12. When the gear A12 rotates, it drives the gear B13 to rotate through meshing transmission, thereby causing the threaded rod 14 to rotate as well, realizing the transmission of power from the motor 11 to the threaded rod 14.

[0033] A slider 15 is threaded onto the outer surface of the threaded rod 14. A connecting bracket 16 is fixedly connected to the surface of the slider 15. The end of the connecting bracket 16 away from the slider 15 is fixedly connected to the movable frame 3. When the threaded rod 14 rotates, it drives the slider 15 to move. The slider 15 drives the movable frame 3 to slide through the connecting bracket 16, thereby realizing the automatic adjustment of the position of the upper clamping plate 4.

[0034] Fastening component 8 can be a smooth-surfaced fastener or a fastener with equidistant grooves on its surface. Smooth fasteners are suitable for pipes with regular surfaces, while grooved fasteners can enhance the friction with the pipe surface. The two options can be adapted to the actual situation of the pipe to further improve the clamping and fixing effect and ensure the stability of the pipe.

[0035] Working principle: The fixed base 1 is fixed to the ceiling or ground with bolts through the screw holes 9 on both sides of the top. After the motor 11 is started, its output end drives the gear A12 to rotate. The gear A12 meshes with the gear B13 on the outer surface of the threaded rod 14, causing the threaded rod 14 to rotate. When the threaded rod 14 rotates, the slider 15 on the outer surface moves along it. The slider 15 drives the movable frame 3 on the surface of the support frame 2 to slide through the connecting bracket 16. The upper clamping plate 4 at the bottom of the movable frame 3 moves accordingly. The upper clamping plate 4 and the lower clamping plate 7 cooperate to initially position the pipe. The lower clamping plate 7 is fixed on the L-shaped clamping plate base 6 through the bracket. The clamping plate base 6 is fixed to the bottom of the side plate 5 on the surface of the fixed base 1. Turning the knob 19 drives the fastening screw 17 to rotate in the threaded cylinder 18. The fastening component 8 at the top of the fastening screw 17 slides along the inside of the lower clamping plate 7, thereby further clamping and fixing the gap between the pipe and the clamping plate, increasing the clamping force and effect, and realizing the support and fixation of the fire sprinkler pipe by the end bracket.

[0036] Example 1: (Reference) Figure 2 )

[0037] A smooth-surfaced fastening component 8 is selected. This fastening component 8 is rotatably connected to the top of the fastening screw 17 and slidably connected inside the lower clamping plate 7. When the operator turns the knob 19, the knob 19 drives the fastening screw 17 to rotate inside the threaded cylinder 18, thereby pushing the fastening component 8 to slide smoothly along the inside of the lower clamping plate 7. Because the surface of the fastening component 8 is smooth, it can effectively avoid scratches and other damage to the outer wall of the pipe during the process of contacting the pipe and applying clamping force. It is especially suitable for pipes with special coatings such as anti-corrosion and anti-rust coatings on the outer wall, or pipe materials that are relatively fragile (such as some plastic pipes). With the initial clamping of the upper clamping plate 4 and the lower clamping plate 7, it can ensure sufficient clamping force to prevent pipe displacement, and maximize the protection of the appearance integrity and structural stability of the pipe. It significantly improves the adaptability of the support to special materials and coated pipes, and reduces the later pipe maintenance costs.

[0038] Example 2: (Reference) Figure 4 )

[0039] A fastening component 8 with equidistant grooves on its surface is used. This fastening component 8 is also rotatably connected to the fastening screw 17 and slidably disposed inside the lower clamping plate 7. When the fastening screw 17 is rotated inside the threaded cylinder 18 by the knob 19, causing the fastening component 8 to move towards the pipeline, the equidistant grooves on its surface can form a tighter engagement with the outer wall of the pipeline, significantly increasing the contact friction between the two. Even when the pipeline vibrates due to water flow impact during the operation of the fire sprinkler system, or when there is external vibration interference in the installation environment (such as the operation of large equipment nearby), it can effectively prevent vibration. It reduces pipe displacement and shaking at the clamping point, maintaining a stable clamping state during long-term use. With the precise thread transmission of the threaded cylinder 18 and the fastening screw 17, it can achieve precise control of the lifting stroke of the fastening component 8, ensuring that the clamping force is evenly applied to the pipe, avoiding excessive local pressure that could damage the pipe, and further improving the reliability and stability of the clamping fixation. It can fully meet the installation scenarios of fire sprinkler pipes in factories, logistics warehouses and other places where the pipe clamping stability requirements are high, effectively reducing the risk of fire hazards caused by pipe loosening.

[0040] Example 3: (Reference) Figure 1-4 )

[0041] Smooth-surface fastening components 8 are suitable for locations with high requirements for pipeline protection, such as hospitals, laboratories, and precision electronics workshops. Fire sprinkler pipes in these locations are often coated with special antibacterial and corrosion-resistant coatings, or use softer engineering plastic pipes. Smooth fastening components 8 will not damage the pipe coating during clamping, nor will they cause physical damage to fragile pipe materials, ensuring the pipeline's corrosion resistance, sealing performance, and service life, and ensuring the reliable operation of the fire protection system in special environments. Fastening components 8 with equidistant grooves on their surface are suitable for factory workshops (such as machining workshops and textile workshops). In scenarios such as large warehouses (e.g., cargo storage warehouses, raw material warehouses) where vibrations are likely to occur or where pipelines need to withstand large water flow impacts for extended periods, the pipelines are more affected by the external environment. The grooved structure can firmly fix the pipeline by enhancing friction, preventing the pipeline from shifting or loosening due to vibration or water flow impact. This ensures that the fire sprinkler pipeline can maintain a stable posture during a fire and successfully complete the water spraying and fire extinguishing operation. The two fastening components can be flexibly selected according to the characteristics of the actual installation environment, the material and coating of the pipeline, greatly improving the applicability of the end bracket and meeting the fire protection installation needs in different scenarios.

[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
