Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a half joint auxiliary anti-slip structure. Background Art

[0002] Pipes in urban water supply and drainage systems may be damaged or leak due to various reasons during use, so they need to be repaired in time. As a common repair device, the Huff quick connector, also known as the Huff joint, consists of two semi-tubular casting halves, two rubber parts and bolts;

[0003] After searching, the patent number is CN210372529U, which discloses a half joint auxiliary anti-detachment device. When in use, the sealing part is embedded in the straight groove and arc groove arranged circumferentially on the side of the half joint half body in the pipe length direction and the pipe end part. The two halves together with the sealing ring are enclosed on the pipe to be repaired, and the nuts and bolts are connected to achieve the deformation of the sealing ring to be in a reliable sealing state, thereby ensuring that the ruptured part of the pipe joint or the pipe body is enclosed to eliminate the leakage point. However, the connection between the half joint and the half joint half ring of the device is relatively simple. When the half joint vibrates and shakes, the half joint and the half joint half ring will be separated, which is inconvenient to use. For this reason, we propose a half joint auxiliary anti-detachment structure. Utility Model Content

[0011] Preferably, a sealing gasket is fixedly connected to the inner side of the half joint near the two sides, and a latch tooth is fixedly connected to the inner side wall of the sealing gasket.

[0012] By adopting the above technical solution, after the half joint and the half joint half ring are connected to the pipeline, the third bolt is inserted into the half joint half ring, so that the half joint half ring is more stably connected to the pipeline under the cooperation of the third bolt and the first nut, and then the fourth nut is rotated to make the connection between the fourth nut and the second bolt disappear, and then the second bolt is rotated to make the second bolt rotate in the connecting arc plate on the left, so that the second bolt moves to the connecting arc plate on the right and then stops, and then the fourth nut is rotated to make the second bolt and the fourth nut connect the half joint half ring and the half joint through the connecting arc plate, and through the cooperation of the cross plate and the limiting plate, When the half joint vibrates, it will squeeze the connecting arc plate above the half joint half ring, so that the half joint half ring squeezes the pipeline, so that the half joint half ring will not be separated from and displaced from the half joint and the pipeline, and with the cooperation of the fourth nut and the second bolt, the spacing between the half joint half ring and the half joint can be adjusted, so that when the half joint vibrates, the half joint and the half joint half ring will not be separated from and displaced, and the spacing between the half joint half ring and the half joint can be adjusted, so that the half joint auxiliary anti-detachment structure can adapt to more situations, thereby improving the functionality of the half joint auxiliary anti-detachment structure;

[0013] By adopting the above technical scheme, after wrapping the half joint with the pipeline, the fourth bolt is inserted into the side plate so that the side plate and the surface of the side plate overlap, and then the second nut is rotated so that the second nut is fixed to the half joint through the cooperation of the fourth bolt and the side plate, so that the half joint is connected to the pipeline, and then the first limit plate is placed under the second nut so that the first limit plate and the second nut are fit, and then the second limit plate and the first limit plate are fixed through the cooperation of the threaded column and the third nut.
