Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, specifically to a pipeline connection device for construction. Background Technology

[0002] Piping systems play a vital role in building and infrastructure projects, transporting water, gas, oil, natural gas, and other fluids. During construction, pipelines need to be strategically laid out according to requirements, and their efficient and safe connections must be ensured. Appropriate connection devices are crucial to ensuring the long-term stable operation of pipelines.

[0003] Patent specification CN 218671000U discloses a pipe connection device for construction. It includes a main clip, with a first clip fixedly connected to one end and a second clip fixedly connected to the other end. A second leakage sensor is fixedly connected to one end of the first clip, and a first leakage sensor is fixedly connected to one end of the second clip. A fixing layer is fixedly connected inside the main clip, and a waterproof layer is fixedly connected inside the fixing layer. This invention, by using the first and second clips fixedly connected to both ends of the main clip, can increase the fixing length. Compared to shorter connection devices, this device has a significant advantage in pipe connection length. The second and first leakage sensors fixedly connected to both ends of the first and second clips allow for immediate detection of leaks, facilitating subsequent repairs and adjustments.

[0004] However, in implementing the relevant technology, the above-mentioned construction pipe connection device has the following problems: the pipe connection device is connected by multiple sets of bolts, which is inconvenient to disassemble and assemble. At the same time, when in use, the water pipe will vibrate due to the impact of water flow, which can easily loosen the bolts and the pipe connection. Therefore, we propose a construction pipe connection device. Utility Model Content

[0005] This utility model proposes a pipe connection device for construction, which solves the problems of inconvenient pipe connection and disassembly, easy vibration of pipes due to water flow impact, and easy loosening of pipe connections in related technologies.

[0006] The technical solution of this utility model is as follows:

[0007] A construction pipe connection device includes a first pipe, a second pipe, and a limiting sleeve. The inner wall of the second pipe has evenly distributed mounting holes, and steel balls are movably installed on the inner wall of each mounting hole. The outer wall of the first pipe has a limiting groove, and the first pipe is movably connected to the second pipe through the limiting groove. The outer wall of the second pipe has a pressing block, and the limiting sleeve is movably installed on the second pipe through the pressing block. A third spring is installed on the outer wall of the second pipe. A fixed threaded sleeve is movably installed on the outer wall of the first pipe, and the first pipe is fixedly connected to the limiting sleeve through the fixed threaded sleeve. Both the first and second pipes have mounting rings on their inner walls, and magnetic blocks are evenly distributed on the outer wall of each mounting ring. A first mating ring and a second mating ring are movably installed on the inner walls of the first and second pipes through the mounting rings. A first spring is connected to the outer wall of the first mating ring, and a first mating hole is provided at one end of the first spring. A second spring is connected to the outer wall of the second mating ring, and a second mating hole is provided at one end of the second spring.

[0008] Preferably, the outer walls of the first and second docking rings are uniformly provided with magnetic suction holes, and the magnetic suction block fits into the magnetic suction holes.

[0009] Preferably, both the first and second docking holes are conical in shape, and the outer walls of the first and second docking holes are uniformly provided with diversion holes.

[0010] Preferably, the front ends of the first and second mating holes are provided with mating hole grooves, and the mating hole grooves are matched with each other.

[0011] Preferably, the mounting hole has an elliptical through-hole structure, and the diameter of the steel ball is smaller than the middle diameter of the mounting hole and larger than the diameters at both ends.

[0012] Preferably, the inner wall of the limiting sleeve is provided with a limiting block, and the limiting block is located on the outer wall of the mounting hole.

[0013] Preferably, the outer wall of the limiting sleeve is provided with an external thread, and the inner wall of the fixing threaded sleeve is provided with an internal thread that matches the external thread.

[0014] Preferably, the limiting groove has an annular groove structure, and the limiting groove fits into the steel ball.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] In this invention, a limiting sleeve, a third spring, and a limiting block are used. Pulling the limiting sleeve compresses the third spring via the squeezing block, causing the limiting block to move away from the outer wall of the steel ball. This allows the mounting hole to move freely within the inner wall of the steel ball. The front end of the first pipe is inserted into the inner wall of the second pipe, aligning the front end of the first mating hole with the second mating hole. Releasing the limiting sleeve causes the third spring to reset due to its elastic force, which in turn moves the limiting block. When the limiting block abuts against the outer wall of the fixed threaded sleeve, rotating the fixed threaded sleeve allows the limiting sleeve to reset through the external thread on the outer wall of the limiting sleeve and the internal thread on the inner wall of the fixed threaded sleeve. This resets the limiting sleeve and moves the limiting block to the outer wall of the mounting hole, squeezing the steel ball. Because the mounting hole is elliptical, the bottom of the steel ball moves out of the mounting hole and engages with the limiting groove on the outer wall of the first pipe under the squeezing of the limiting block, thus connecting the first and second pipes. This structure facilitates pipe connection and disassembly.

[0017] In this invention, a first pipe, a second pipe, and mounting rings are provided. Since mounting rings are provided on the inner walls of both the first and second pipes, and magnetic blocks are evenly distributed on the outer walls of the mounting rings, the inner walls of the first and second pipes are magnetically attached to the second and first docking holes, respectively. When water flows into the first and second docking holes, it compresses the first and second springs. The elastic force generated by the compression of the first and second springs partially offsets the impact force of the water flow, preventing vibration of the first and second pipes caused by the water flow impact. This structure can prevent the pipe connections from becoming loose and facilitates the disassembly and replacement of the first and second springs. Attached Figure Description

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1: As Figures 1-5 As shown, this embodiment proposes a construction pipe connection device, including a first pipe 1, a second pipe 2, and a limiting sleeve 4. The inner wall of the second pipe 2 is uniformly provided with mounting holes 18, and steel balls 19 are movably installed on the inner wall of the mounting holes 18. The outer wall of the first pipe 1 is provided with a limiting groove 17, through which the first pipe 1 is movably connected to the second pipe 2. The outer wall of the second pipe 2 is provided with a pressing block 14, through which the limiting sleeve 4 is movably installed. A third spring 15 is installed on the outer wall of the second pipe 2, and the first pipe 1 is movably installed on the outer wall of the first pipe 1. A fixed threaded sleeve 3 is provided. The first pipe 1 is fixedly connected to the limiting sleeve 4 through the fixed threaded sleeve 3. The inner walls of the first pipe 1 and the second pipe 2 are provided with mounting rings 6. The outer walls of the mounting rings 6 are evenly provided with magnetic blocks 7. The inner walls of the first pipe 1 and the second pipe 2 are movably installed with a first docking ring 5 and a second docking ring 10 through the mounting rings 6. The outer wall of the first docking ring 5 is connected with a first spring 8. One end of the first spring 8 is provided with a first docking hole 9. The outer wall of the second docking ring 10 is connected with a second spring 11. One end of the second spring 11 is provided with a second docking hole 12.

[0027] In this embodiment, the mounting hole 18 has an elliptical through-hole structure, and the diameter of the steel ball 19 is smaller than the middle diameter of the mounting hole 18 and larger than the diameters at both ends.

[0028] In this embodiment, a limiting block 16 is provided on the inner wall of the limiting sleeve 4, and the limiting block 16 is located on the outer wall of the mounting hole 18.

[0029] In this embodiment, the outer wall of the limiting sleeve 4 is provided with an external thread, and the inner wall of the fixing threaded sleeve 3 is provided with an internal thread that matches the external thread.

[0030] In this embodiment, the limiting groove 17 has an annular groove structure, and the limiting groove 17 fits into the steel ball 19.

[0031] Specific examples Figure 1 , Figure 3 and Figure 4 As shown, when using this structure, pulling the limiting sleeve 4 compresses the third spring 15 through the squeezing block 14, causing the limiting block 16 to move away from the outer wall of the steel ball 19, allowing the mounting hole 18 to move freely on the inner wall of the steel ball 19. The front end of the first pipe 1 is inserted into the inner wall of the second pipe 2, so that the front end of the first mating hole 9 aligns with the second mating hole 12. Releasing the limiting sleeve 4 causes the third spring 15 to reset due to the elastic force generated by its deformation, which in turn moves the limiting block 16. When the limiting block 16 abuts against the outer wall of the fixed threaded sleeve 3... When the fixed threaded sleeve 3 is rotated, the external thread on the outer wall of the limiting sleeve 4 and the internal thread on the inner wall of the fixed threaded sleeve 3 are used to reset the limiting sleeve 4, causing the limiting block 16 to move to the outer wall of the mounting hole 18 and squeeze the steel ball 19. Since the mounting hole 18 has an elliptical hole structure, the bottom of the steel ball 19 will move out of the mounting hole 18 and be inserted into the limiting groove 17 on the outer wall of the first pipe 1 under the squeezing of the limiting block 16, so that the first pipe 1 and the second pipe 2 are connected. This structure facilitates pipe connection and disassembly.

[0032] Example 2: The outer walls of the first docking ring 5 and the second docking ring 10 are uniformly provided with magnetic suction holes 13, and the magnetic suction block 7 fits into the magnetic suction holes 13.

[0033] In this embodiment, the front ends of the first mating hole 9 and the second mating hole 12 are provided with mating hole grooves, and the mating hole grooves match each other.

[0034] Specific examples Figure 1 , Figure 2 and Figure 5 As shown, when using this structure, since the inner walls of the first pipe 1 and the second pipe 2 are both provided with mounting rings 6 and magnetic blocks 7 are evenly distributed on the outer wall of the mounting rings 6, the inner walls of the first pipe 1 and the second pipe 2 are respectively magnetically attached to the second docking hole 12 and the first docking hole 9 through the mounting rings 6. When the water flow impacts the first docking hole 9 and the second docking hole 12, it will compress the first spring 8 and the second spring 11. The elastic force generated by the compression of the first spring 8 and the second spring 11 is used to partially offset the impact force of the water flow, avoiding the water flow impact force from causing the first pipe 1 and the second pipe 2 to vibrate. This structure can prevent the pipe connection from becoming loose, and at the same time facilitate the disassembly and replacement of the first spring 8 and the second spring 11.

[0035] Working principle: During use, pulling the limiting sleeve 4 compresses the third spring 15 through the squeezing block 14, causing the limiting block 16 to move away from the outer wall of the steel ball 19, allowing the mounting hole 18 to move freely on the inner wall of the steel ball 19. Since the inner walls of both the first pipe 1 and the second pipe 2 are equipped with mounting rings 6, and the outer walls of the mounting rings 6 are evenly distributed with magnetic blocks 7, the inner walls of the first pipe 1 and the second pipe 2 are respectively magnetically attached to the second docking hole 12 and the first docking hole 9 via the mounting rings 6. Inserting the front end of the first pipe 1 into the inner wall of the second pipe 2 causes the front end of the first docking hole 9 to align with the second docking hole 12. Releasing the limiting sleeve 4 causes the third spring 15 to reset due to the elastic force generated by its deformation, moving the limiting block 16. When the limiting block 16 abuts against the outer wall of the fixed threaded sleeve 3, rotating the fixed threaded sleeve 3 allows the external thread on the outer wall of the limiting sleeve 4 to move. The internal thread on the inner wall of the fixed threaded sleeve 3 causes the limiting sleeve 4 to reset, moving the limiting block 16 to the outer wall of the mounting hole 18 and squeezing the steel ball 19. Since the mounting hole 18 has an elliptical hole structure, under the squeezing of the limiting block 16, the bottom of the steel ball 19 will move out of the mounting hole 18 and be engaged in the limiting groove 17 on the outer wall of the first pipe 1, so that the first pipe 1 and the second pipe 2 are connected. In use, when the water flow impacts the first docking hole 9 and the second docking hole 12, it will compress the first spring 8 and the second spring 11. The elastic force generated by the compression of the first spring 8 and the second spring 11 can partially offset the impact force of the water flow, avoiding the impact force of the water flow causing the first pipe 1 and the second pipe 2 to vibrate. This structure can prevent the pipe connection from becoming loose, and at the same time facilitate the disassembly and replacement of the first spring 8 and the second spring 11. In addition, the pipe connection is simple to disassemble and reassemble, and does not require multiple sets of bolts for connection.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
