Description

Technical Field

[0001] The utility model relates to a pipeline plugging device, in particular to a durable and stable pipeline plugging device, belonging to the technical field of pipeline plugging. Background Art

[0002] At present, during the pipeline installation and construction process, two methods are usually used, namely overhead laying and underground laying. The underground laying is further divided into direct burial laying and trench laying. According to the purpose of the building and the different aesthetic requirements, indoor pipeline laying can be divided into open installation and concealed installation.

[0003] During the construction process of pre-buried pipelines, various sewage and foreign matter can easily enter the pipeline through the pipeline opening, so it is necessary to use a pipeline plugger to seal the pipeline opening. However, although the commonly used pipeline pluggers can play a role in sealing the pipeline, they have a simple structure and poor firmness after installation. The plugger is prone to falling off due to the influence of pipeline pressure and operational vibration / shaking, and is not durable and stable enough to use. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a pipeline plugger that can improve the firmness of the pipeline after installation and is durable and stable.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] A durable and stable pipe plugger comprises a pipe body, one end of which is provided with a plugger structure, the plugger structure comprising a fixing plate mounted on the pipe body, a plugging air cushion fixedly mounted on one side of the fixing plate, an air nozzle extending to the outside of the fixing plate fixedly mounted on the plugging air cushion, two fixing frames symmetrically mounted on the fixing plate, a screw connected by a thread is provided on the fixing frame, and a fixing splint is movably mounted on one end of the screw.

[0007] Furthermore, a rubber pad is fixedly mounted on the inner wall of the fixed splint.

[0008] Furthermore, a plurality of power-assisting blocks are fixedly mounted on the other end of the screw rod, and the power-assisting blocks are provided with anti-slip grooves.

[0009] Furthermore, limiting rods are fixedly installed on both sides of the fixing frame, and two limiting plates slidably connected to the limiting rods are fixedly installed on the fixing clamping plate.

[0010] Furthermore, a support plate is provided on the outside of the fixing frame, a spring is installed between the support plate and the limit plate, a magnetic block is fixedly installed on the inner wall of the support plate, and a magnetic plate that is attracted to the support plate is fixedly installed on the surface of the fixing frame.

[0011] Furthermore, a mounting seat is fixedly mounted on the gas nozzle, and a sealing cover is provided on the mounting seat.

[0012] Furthermore, the mounting seat and the sealing cover are arranged to be threadedly connected, and an anti-slip pad is fixedly mounted on the surface of the sealing cover.

[0013] The beneficial effects of the present invention are:

[0014] By setting up the plugger structure, the firmness of the connection with the pipeline body after installation can be improved. After the fixing plate and the sealing air cushion are installed at one end of the pipeline body, the sealing air cushion is inflated through the air nozzle to make it collide with the inside of the pipeline body to seal. After the blockage is formed, the screw is rotated to use the thread to drive the fixed splint to move until the two fixed splints are tightly fitted to the surface of the pipeline body. The two fixed splints clamp the pipeline body to improve the firmness of the installation connection between the fixing plate and the sealing air cushion and the pipeline body, avoid falling off due to the influence of the pressure in the pipeline body during blocking, and improve the long-term stability.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be described clearly and completely below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1-4 As shown, this embodiment provides an embodiment of a durable and stable pipeline plugging device.

[0022] A durable and stable pipe plugger comprises a pipe body 1, one end of which is provided with a plugger structure 2, the plugger structure 2 comprising a fixing plate 3 mounted on the pipe body 1, a plugging air cushion 4 fixedly mounted on one side of the fixing plate 3, an air nozzle 5 extending to the outside of the fixing plate 3 fixedly mounted on the plugging air cushion 4, two fixing frames 6 symmetrically mounted on the fixing plate 3, a screw 7 connected by a thread is provided on the fixing frame 6, and a fixing splint 8 is movably mounted on one end of the screw 7. By setting up the plugger structure 2, the firmness of the connection with the pipeline body 1 after installation can be improved. After the fixing plate 3 and the sealing air cushion 4 are installed at one end of the pipeline body 1, the sealing air cushion 4 is inflated through the air nozzle 5 so that it collides with the inside of the pipeline body 1 to seal it. After the blockage is formed, the screw 7 is rotated to use the thread to drive the fixing splint 8 to move until the two fixing splints 8 are tightly fitted to the surface of the pipeline body 1. The two fixing splints 8 clamp the pipeline body 1 to improve the firmness of the installation connection between the fixing plate 3 and the sealing air cushion 4 and the pipeline body 1, thereby avoiding falling off due to the influence of the pressure in the pipeline body 1 during blocking, thereby improving the long-term stability.

[0023] A rubber pad 9 is fixedly mounted on the inner wall of the fixed splint 8, and a plurality of boosting blocks 10 are fixedly mounted on the other end of the screw 7. The boosting blocks 10 are provided with anti-slip grooves. A limit rod 11 is fixedly mounted on both sides of the fixed frame 6, and two limit plates 12 are fixedly mounted on the fixed splint 8 and are slidably connected to the limit rod 11. The provision of the rubber pad 9 can further increase the friction between the inner wall of the fixed splint 8 and the surface of the pipe body 1, thereby improving the stability of the two fixed splints 8 in clamping the pipe body 1. The plurality of boosting blocks 10 are evenly distributed on one end of the screw 7, and the anti-slip grooves provided on their surfaces also increase the friction on one end of the screw 7, thereby facilitating the twisting and rotation of the screw 7. Through the provision of the limit rod 11 and the limit plate 12, when the screw 7 drives the fixed splint 8 to move, the limit plate 12 on the fixed splint 8 can limit the fixed splint 8 by sliding on the limit rod 11, so that the fixed splint 8 can move smoothly and avoid skew that affects the stability of the clamping.

[0024] A support plate 13 is provided on the outer side of the fixing frame 6, a spring 14 is installed between the support plate 13 and the limit plate 12, a magnetic block 15 is fixedly installed on the inner wall of the support plate 13, a magnetic plate 16 that is attracted to the support plate 13 is fixedly installed on the surface of the fixing frame 6, a mounting seat 17 is fixedly installed on the air nozzle 5, a sealing cover 18 is provided on the mounting seat 17, a threaded connection is set between the mounting seat 17 and the sealing cover 18, and an anti-slip pad 19 is fixedly installed on the surface of the sealing cover 18. By setting the support plate 13, spring 14, magnet 15 and magnetic plate 16, after the two fixed splints 8 clamp the pipe body 1, under the contraction action of multiple springs 14, the magnet 15 on the support plate 13 is fitted with the magnetic plate 16 on the surface of the fixed frame 6, and the screw 7 can be fixed under the action of magnetic adsorption to prevent the screw 7 from rotating due to collision and causing the fixed splint 8 to loosen; a mounting seat 17 and a sealing cover 18 are set on one end of the air nozzle 5. Since the mounting seat 17 and the sealing cover 18 are threadedly connected, the sealing cover 18 can seal the air nozzle 5 to prevent gas leakage in the sealed air cushion 4, and the anti-slip pad 19 arranged on the surface of the sealing cover 18 facilitates its rotation for easy installation and disassembly.

[0025] like Figure 1-4 As shown, the working process of the durable and stable pipeline plugging device provided by this embodiment is as follows:

[0026] After the fixing plate 3 and the sealing air cushion 4 are installed at one end of the pipe body 1, the sealing air cushion 4 is inflated through the air nozzle 5 so that it collides with the inside of the pipe body 1 to seal it. After the seal is formed, the screw 7 is rotated to use the thread to drive the fixing splint 8 to move until the two fixing splints 8 are tightly fitted to the surface of the pipe body 1. The two fixing splints 8 clamp the pipe body 1 to improve the firmness of the installation connection between the fixing plate 3 and the sealing air cushion 4 and the pipe body 1.
