Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a pipeline connector with stable connection. Background Art

[0002] Pipe connector is a device that uses stainless steel and rubber to form a component combination device to achieve the sealing and pressure-bearing function. It has a very compact structure and can be widely used in the connection of pipes of various materials in industries such as petroleum, chemical industry, offshore platform, electric power, light industry, food, municipal administration, environmental protection and mechanical equipment.

[0003] However, the existing pipe connector lacks a fixing mechanism, which causes the pipe connection end and the pipe connector to rotate randomly during use, and then the connection is prone to loosening, thereby reducing the connection stability between the pipe and the pipe connector. When the medium pressure inside the pipe is insufficient during use, the existing pipe connector is prone to medium leakage. In addition, the fire resistance of the existing pipe connector is poor.

[0004] In view of the above problems, the inventor proposes a pipeline connector with stable connection to solve the above problems. Utility Model Content

[0021] The fixing mechanism 7 includes an L-shaped plate 71, which is fixedly connected to the housing 1, and a U-shaped plate 72 is fixedly connected to the end of the L-shaped plate 71, a stud 73 is rotatably inserted on the U-shaped plate 72, and a symmetrically arranged fixing plate 74 is threadedly sleeved on the stud 73, an end of the fixing plate 74 away from the U-shaped plate 72 is fixedly connected to an arc plate 75, and a guide block 76 is integrally formed on the end of the fixing plate 74 away from the arc plate 75, and a guide groove 77 is opened through the U-shaped plate 72. The guide block 76 is slidably engaged in the guide groove 77, a rubber pad 78 is fixedly connected to the inner wall of the arc plate 75, and an array of anti-skid grooves are provided on the inner wall of the rubber pad 78. The coordinated use of the rubber pad 78 and the anti-skid grooves can effectively improve the tightness of the fit between the arc plate 75 and the outer wall of the pipe fitting. Both ends of the stud 73 are fixedly connected to a hand wheel 79, and the outer wall of the hand wheel 79 is covered with a layer of anti-skid patterns. The setting and use of the anti-skid patterns can increase friction and facilitate operation.

[0022] By adopting the above technical solution, when in use, any one of the hand wheels 79 on both sides of the knob is turned in turn, so that the corresponding stud 73 can be driven to rotate, and then the corresponding two fixed plates 74 can be driven to move toward each other in coordination with the use of the corresponding guide block 76 and the guide groove 77, thereby driving the corresponding two arc plates 75 to move toward each other, and then driving the corresponding two rubber pads 78 to move toward each other, until the inner wall of the rubber pad 78 is tightly fitted on the outer wall of the corresponding pipe fitting.
