Description
Technical Field
[0001] The utility model relates to the technical field of pipe connectors, and particularly relates to a locking device for pipe fittings joints. Background Technique
[0002] Pipe fittings joints are used to connect multiple sections of pipes. They are detachable connectors that achieve tight connection between pipes through different connection methods such as welding, threading, ferrule, and flaring.
[0003] The existing Chinese utility model patent with the publication number CN216812409U: a locking device for pipe fittings joints. This application includes a first hoop plate, a second hoop plate is arranged below the first hoop plate. Two fixed rods are fixedly connected to the upper surface of the second hoop plate. An adjusting inclined groove is opened on the right side surface of the fixed rod. Two limit sliding grooves are opened on the upper surface of the first hoop plate. An adjusting inclined block is slidably connected to the inner wall of the limit sliding groove. The outer surface of the adjusting inclined block and the left side surface of the inner wall of the limit sliding groove are fixedly connected with the same elastic telescopic rod. An adjusting U-shaped rod is slidably connected to the upper surface of the first hoop plate. The upper surface of the first hoop plate is rotatably connected with a first adjusting screw through a bearing. The inner wall of the adjusting U-shaped rod is threadedly connected to the inner wall of the first adjusting screw. And this application can solve the problems of the existing pipe fittings joints, such as complex operation, inconvenient installation and disassembly, etc. However, in this application, the clamping and fixing of the pipe connection part is realized between the first hoop plate and the second hoop plate by means of an adjusting U-shaped rod, a first adjusting screw, a second adjusting screw and a limit arc plate. But it is difficult for this application to solve the sealing problem after the connection of two sections of pipes. Even if a traditional sealing ring is placed between the two sections of pipes, and since one end of the pipe needs to be hermetically inserted into the sealing ring, after the pipe is placed between the two limit arc plates, the friction between the pipe and the sealing ring increases, so that it is difficult to continue to push the pipe to be tightly connected with the sealing ring. Furthermore, it is easy to cause the pipe to be separated from the sealing ring and the limit arc plate due to pressure during the later transmission of the medium. Content of the Utility Model
[0004] The purpose of the utility model is to provide a locking device for pipe fittings joints, which can effectively solve the problems in the background technique.

Based on this, by arranging the sealing pipe and the inner socket in the first hoop assembly and the second hoop assembly, one ends of two sections of pipelines can be respectively inserted into the first hoop assembly and the second hoop assembly and play a sealing role. At the same time, with the help of two displaceable semi-circular pull rods on both sides of the first hoop assembly and the second hoop assembly, the pipeline can be pressed and moved towards the sealing gasket side, so that one end of the pipeline can be inserted more tightly between the sealing pipe and the inner socket.

A first fixed shaft 8 is fixedly installed inside the second mounting seat 18. One side of the buckle 3 is rotatably installed on the first fixed shaft 8. The first mounting seat 4 is in a C-shaped structure. A second fixed shaft 9 is fixedly installed inside the first mounting seat 4. Based on this, after the first hoop assembly 1 and the second hoop assembly 2 are movably connected by a hinge 7, the buckle 3 can be buckled on the second fixed shaft 9 by using the card slot on one side of the bottom, so as to cooperate with the sealing pipe 5 to realize the clamping and binding of the pipeline;
[0022] As Figures 2-4 shown, screw grooves 10 are provided on both sides of the first hoop assembly 1 located on both sides of the first fixed shaft 8, and screw grooves 10 are also provided on both sides of the second hoop assembly 2 located on both sides of the first mounting seat 4. Based on this, by providing two screw grooves 10 on the outside of the first hoop assembly 1 and the second hoop assembly 2 respectively, the two semi-circular pull rods 6 on the same side of the first hoop assembly 1 and the second hoop assembly 2 can be combined and rotated circumferentially in the two screw grooves 10. An inner socket 11 is fixedly installed inside the sealing pipe 5. The inner socket 11 is in a double-direction frustum shape structure. A sealing pad 12 is also fixedly connected between the inner socket 11 and the sealing pipe 5. The sealing pipe 5 is inserted and installed inside the first hoop assembly 1 and the second hoop assembly 2. One side of the semi-circular pull rod 6 is fixedly installed with a semi-circular connecting plate 13. One side of the semi-circular connecting plate 13 is fixedly installed with a semi-circular threaded plate 14. The other side of the semi-circular pull rod 6 is fixedly installed with a multi-sided seat 15. An installation groove 16 is provided inside the semi-circular pull rod 6. A rubber friction pad 17 is clamped in the installation groove 16. The semi-circular threaded plate 14 is threadedly connected in the screw groove 10. Based on this, by arranging the sealing pipe 5 and the inner socket 11 inside the first hoop assembly 1 and the second hoop assembly 2, one end of the two pipelines can be respectively inserted and installed inside the first hoop assembly 1 and the second hoop assembly 2 and play a sealing role. At the same time, with the help of the two displaceable semi-circular pull rods 6 on both sides of the first hoop assembly 1 and the second hoop assembly 2, the pipeline can be pressed and moved towards the sealing pad 12 side, so that one end of the pipeline can be inserted more tightly between the sealing pipe 5 and the inner socket 11.

When connecting two sections of pipes, the sealing pipe 5 can be inserted and installed on one end of one section of the pipe first, and the inner socket 11 can be inserted and installed inside the pipe. Then, one end of the other section of the pipe is inserted and installed on the other side of the sealing pipe 5 in the same way. Subsequently, the first hoop assembly 1 and the second hoop assembly 2 can be placed outside the sealing pipe 5, and the first hoop assembly 1 and the second hoop assembly 2 can be rotated and closed through the hinge 7, so that one side of the buckle 3 rotates on the first fixed shaft 8, and the slot at the bottom side of the buckle 3 is buckled on the second fixed shaft 9, so that the first hoop assembly 1 and the second hoop assembly 2 can apply a wrapping pressure to the sealing pipe 5, so that the cooperation of the sealing pipe 5, the inner socket 11, the first hoop assembly 1 and the second hoop assembly 2 can initially seal and connect the two sections of pipes. Then, the two semi-circular pull rods 6 on one side of the first hoop assembly 1 and the second hoop assembly 2 and the two multi-sided seats 15 on one side can be rotated by using tools such as a wrench. Thus, the two semi-circular pull rods 6 drive the semi-circular connecting plates 13 and the semi-circular threaded plates 14 on one side to rotate respectively, and the combined position of the two semi-circular threaded plates 14 is an annular structure and rotates in the screw grooves 10 on the same side of the first hoop assembly 1 and the second hoop assembly 2. Furthermore, the semi-circular pull rods 6 cooperate with the rubber friction pads 17 to continue to pull the sealing pipe 5 on one side of the pipe, so that one end of the pipe is closely attached to one side of the sealing pad 12, so that the sealing pipe 5 and the inner socket 11 can be completely inserted and installed on the outside and inside of one end of the pipe, thereby improving the connection strength and sealing performance of the two sections of pipes.
