[0002] Fire pipe clamps are commonly used connecting components in fire pipe systems. They are mainly used to achieve quick connection and fixation between pipes, simplifying the operation process during pipe installation, inspection, or maintenance, reducing reliance on complex connection techniques. They are highly adaptable and can be used with fire pipes of different specifications to ensure that the pipes remain stable after connection, preventing the normal operation of the fire protection system from being affected by loose connections. At the same time, they can play a certain role in adjusting for slight displacement of pipes due to temperature changes or other factors, ensuring the overall sealing and safety of the fire pipe system, and providing a basic guarantee for the effective activation of the fire protection system in emergency situations.

[0003] In the installation and maintenance of fire protection pipelines, traditional clamps often require the use of tools such as wrenches to tighten them. The operation is cumbersome and time-consuming. Especially in installation scenarios with limited space, the limited use of tools leads to low installation efficiency. Furthermore, the disassembly and reassembly process during later maintenance is complicated, increasing maintenance costs and time costs. Therefore, a new type of clamp for fire protection pipelines is needed. 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 a fire-fighting pipe clamp that can solve the problems of low installation efficiency due to the need for multiple tools and cumbersome operation, and high maintenance costs due to the complexity of inspection, disassembly and assembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire-fighting pipe clamp, comprising an upper clamp and a convenient fastening and sealing structure.

The guide blocks are slidably connected to the side plates. The telescopic plates are slidably connected inside the sliding fasteners. The bottom of the telescopic plates is fixedly connected to the sliding fasteners by springs. The limiting blocks are fixedly connected to the surface of the telescopic plates and engage with the corresponding limiting grooves.

[0006] Preferably, the convenient fastening and sealing structure further includes a fastening movable plate, a width-gradient convex ridge, and a buffer structure. The fastening movable plate is slidably connected inside the upper clamp, the width-gradient convex ridge is fixedly connected to the top of the fastening movable plate, and the buffer structure is set at the bottom of the fastening movable plate and is in contact with the pipeline.

[0007] Preferably, the sliding fastener is slidably connected to the width-gradient convex ridge, and the surface of the side plate is provided with a guide groove for the guide block to slide.

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

[0015] 1. This fire-fighting pipe clamp features a convenient fastening and sealing structure. Through the cooperation of side plates, sliding fasteners, and limiting components, it achieves rapid fastening without additional tools, simplifying the operation process and improving installation and maintenance efficiency. The sliding cooperation of the fastening movable plate and the gradually wide convex ridge allows for adjustment of the fastening force according to the actual situation of the pipe, ensuring a stable clamping effect for pipes of different specifications.

Detailed Implementation

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

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.

[0027] 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.

[0028] Please see Figure 1-6This utility model provides a technical solution: a clamp for fire-fighting pipelines, wherein:

[0029] The upper clamp 1 and the lower clamp 2 are movably connected, and grooves 3 are opened on the opposite sides of both. When in use, the two are placed on both sides of the pipe, and the grooves 3 fit against the outer wall of the pipe to provide initial positioning for the pipe and ensure accurate subsequent tightening operations. This matching method can quickly complete the initial assembly of the clamp and the pipe and improve the ease of installation.

[0030] The lower clamp 2 is slidably connected to the movable clamp 7, and the lower clamp 2 has a groove 6 for the movable clamp 7 to move. The bottom of the movable clamp 7 is fixedly connected to the handle 9. Pushing the handle 9 can drive the movable clamp 7 to move smoothly along the groove 6. The groove 6 restricts the direction of movement of the movable clamp 7 to avoid deviation and ensure that the movable clamp 7 can accurately align with the upper clamp 1.

[0031] The movable clip 7 passes through the slot A4 opened on the surface of the upper clamp 1. The movable clip 7 has a slot B8 opened on its surface. The upper clamp 1 has an anti-slip ridge 5. When the movable clip 7 moves to the designated position, the slot B8 contacts and locks with the anti-slip ridge 5. The anti-slip properties of the anti-slip ridge 5 enhance the locking stability, thus achieving the initial fixation of the upper clamp 1 and the lower clamp 2.

[0032] The upper clamp 1 has two side plates 13 symmetrically fixedly connected to its surface. The sliding fastener 15 is slidably connected to the surface of the side plate 13. The sliding fastener 15 has guide blocks 17 symmetrically fixedly connected to both sides. The side plate 13 has a guide groove 16 for the guide block 17 to slide. When the sliding fastener 15 is slid, the guide block 17 slides along the guide groove 16, providing stable guidance for the sliding fastener 15 and preventing it from deviating when sliding.

[0033] The sliding fastener 15 is internally connected to the telescopic plate 18. The bottom of the telescopic plate 18 is fixedly connected to the sliding fastener 15 by a spring. The surface of the telescopic plate 18 is fixedly connected to the limiting block 19. The side plate 13 has equidistant limiting grooves 14. When the sliding fastener 15 slides to the appropriate position, the spring pushes the telescopic plate 18 to move, so that the limiting block 19 is engaged in the corresponding limiting groove 14, locking the position of the sliding fastener 15 and ensuring that the fastening force does not decrease.

[0034] The upper clamp 1 has an internal sliding connection to the fastening movable plate 10. The top of the fastening movable plate 10 is fixedly connected to the width-gradient protrusion 11. The sliding fastener 15 is slidably connected to the width-gradient protrusion 11. When the sliding fastener 15 moves, it pushes the fastening movable plate 10 downward by cooperating with the width-gradient protrusion 11. The downward pressure of the fastening movable plate 10 can be adjusted according to the pipe specifications to adapt to pipes of different diameters.

[0035] A buffer structure 12 is provided at the bottom of the fastening movable plate 10. The buffer structure 12 can be an elastic buffer sealing gasket or a rigid buffer plate connected by a spring. When the fastening movable plate 10 moves downward, the buffer structure 12 is in close contact with the pipe surface. The elastic buffer sealing gasket can directly fit the pipe through elasticity, while the rigid buffer plate is buffered by the spring force. This not only enhances the sealing performance to prevent leakage, but also absorbs the impact force of pipe vibration and avoids damage to the pipe from hard contact with the clamp.

[0036] Working principle: In use, first place the upper clamp 1 and the lower clamp 2 on both sides of the pipe, allowing the movable clamp 7 to pass through the groove A4 of the upper clamp 1. Then, push the handle 9 to move the movable clamp 7 along the slide groove 6 until the groove B8 on the surface of the movable clamp 7 contacts and locks with the anti-slip edge 5 of the upper clamp 1, initially fixing the upper and lower clamps. Next, slide the sliding fastener 15 to move it along the surface of the side plate 13 and the guide groove 16. During the process, the guide block 17 plays a guiding role. When the sliding fastener 15 moves, it touches the top of the fastening movable plate 10. The tapered ridge 11 of the part slides and engages, pushing the fastening movable plate 10 downward, so that the buffer structure 12 fits tightly against the pipe surface. The telescopic plate 18 slides inside the sliding fastener 15, and the spring assists in its reset, allowing the limiting block 19 to engage in the limiting groove 14 of the side plate 13, locking the position of the sliding fastener 15. Furthermore, the reaction force further enhances the clamping of the groove B8 and the upper clamp 1. The same convenient fastening and sealing structure can be added to the lower clamp 2 as needed, finally completing the fastening and sealing of the fire pipeline.

[0037] Example 1: (Reference) Figure 3 )

[0038] The buffer structure 12 uses an elastic buffer sealing gasket. When the sliding fastener 15 slides along the side plate 13, the guide block 17 guides along the guide groove 16, and together with the width-gradient convex rib 11, pushes the fastening movable plate 10 down, so that the elastic buffer sealing gasket is in close contact with the pipe surface. The elastic buffer sealing gasket can quickly fill the gap between the pipe and the fastening movable plate 10 by means of its own elasticity, effectively improving the sealing performance between the clamp and the pipe, preventing fluid leakage. Moreover, the elastic material has good aging resistance and is not prone to sealing failure after long-term use. At the same time, it can buffer the slight vibration of the pipe and avoid damage from hard friction between the pipe and the clamp. It is suitable for the sealing requirements of pipes of various diameters and improves the stability of the clamp.

[0039] Example 2: (Reference) Figure 2 )

[0040] The buffer structure 12 uses a rigid buffer plate connected by a spring. During the downward movement of the fastening movable plate 10, the rigid buffer plate first contacts the pipe surface. As the fastening movable plate 10 continues to press down, the spring is compressed. With the help of the spring force, the pressure can be automatically adjusted according to the flatness of the pipe surface to ensure that the rigid buffer plate fits tightly with the pipe surface. This ensures both the fastening effect and avoids pipe deformation due to excessive pressure. The rigid buffer plate is made of high-strength material and can withstand large external impacts. It is suitable for use in scenarios with high pipe vibration frequencies. With the locking of the limit block 19 and the limit groove 14, a stable buffering and fastening state can be maintained for a long time, extending the service life of the clamp.

[0041] Example 3: (Reference) Figure 1-6 )

[0042] Clamps with elastic buffer sealing gaskets are suitable for indoor fire protection pipeline installation scenarios, such as fire branch pipes in office buildings and residential buildings. In such scenarios, pipeline vibration is small and high sealing requirements are required. Elastic buffer sealing gaskets can effectively prevent fluid leakage in pipelines and ensure the stable operation of indoor fire protection systems.

[0043] Example 4: (Reference) Figure 1-6 )

[0044] In the scenario of connecting pipes to small fire hydrants along municipal roads, a convenient fastening and sealing structure can meet the requirements. In this scenario, the pipe diameter is small and the force is stable. A convenient fastening and sealing structure including a side plate 13, a sliding fastener 15, a guide block 17, a telescopic plate 18, a limit block 19, a fastening movable plate 10, a width-gradient convex rib 11, and an elastic buffer sealing pad-type buffer structure 12 can push the fastening movable plate 10 down through the cooperation of the sliding fastener 15 and the width-gradient convex rib 11, so that the buffer structure 12 fits tightly against the pipe, quickly achieving stable fastening and sealing, reducing the number of parts used and reducing costs.

[0045] In the scenario of fire protection main pipeline in a large commercial complex, two convenient fastening and sealing structures need to be installed on the upper clamp 1 and the lower clamp 2 respectively. The main pipeline has a large diameter and high fluid pressure. The two structures can apply force from both sides simultaneously. The fastening force is balanced by locking the limiting block 19 and the limiting groove 14. The rigid buffer plate buffer structure 12 absorbs pipeline vibration, enhances the overall connection stability, avoids seal failure due to uneven force on one side, and ensures the reliable operation of the fire protection system.

[0046] The clamps that use springs to connect rigid buffer plates are suitable for fire protection main pipelines in industrial plants. The operation of equipment in industrial plants can easily cause pipeline vibration. The rigid buffer plates, together with springs, can effectively absorb the impact of vibration, prevent pipeline damage, and at the same time ensure the tightness and sealing of the main pipeline, thus meeting the needs of industrial fire protection.

[0047] 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.
