Technical Field

[0001] This utility model relates to the technical field of high-sealing pneumatic pipe joints, specifically a high-sealing pneumatic pipe joint. Background Technology

[0002] Pipe fittings are connecting tools between pipes, serving as detachable connection points between components and pipes. They play an indispensable and crucial role in pipe fittings, being one of the two main components of a pipeline. As a key connecting component in a pneumatic system, the sealing performance of pneumatic fittings directly affects the operational stability and safety of the entire pneumatic system. Most pneumatic pipe fittings employ threaded or snap-fit ​​connections. Threaded connections are prone to loosening under vibration, further exacerbating the risk of leakage.

[0003] Therefore, a high-sealing pneumatic hose connector is needed to improve the above-mentioned problems. Utility Model Content The purpose of this invention is to provide a high-sealing pneumatic pipe connector to solve the problems mentioned in the background art.

The limiting component includes a limiting ring. The limiting ring has first limiting holes symmetrically opened on its side, and second limiting holes symmetrically opened on its side, front and back. A movable ring is provided on the right side of the limiting ring. A first limiting rod is symmetrically arranged on the left side of the movable ring, and a second limiting rod is symmetrically arranged on the front and back of the left side of the movable ring. A fixed ring is provided on the right side of the movable ring. A pull rod is provided on the upper side between the fixed ring and the movable ring. A first fixing spring is sleeved on the outer wall of the pull rod. A second fixing spring is evenly arranged along the circumferential direction between the fixed ring and the movable ring.

[0005] As a preferred embodiment of this utility model, the threaded tube and the connecting cap are adapted to each other, and the inner side of the connecting cap is adapted to the outer wall of the threaded tube to have an internal thread, and the connecting cap is threadedly connected to the threaded tube.

[0006] The above technical solution allows the connecting cap to be connected to the threaded pipe via threads.

[0007] As a preferred embodiment of this utility model, a first sealing gasket is provided at the right end of the connecting cap, and a second sealing gasket is provided at the left end of the connecting head. The first sealing gasket is made of fluororubber, and the second sealing gasket is made of silicone rubber.

[0008] Through the above technical solutions, fluororubber has excellent high temperature resistance, oil resistance and chemical corrosion resistance, while silicone rubber has good elasticity and sealing properties. The sealing performance can be further improved by using the first sealing gasket and the second sealing gasket.

[0009] In a preferred embodiment of this utility model, the limiting ring is located on the outer wall of the connecting cap and is fixedly connected to the connecting cap. The moving ring and the fixed ring are both located on the outer wall of the connecting head, and the fixed ring is fixedly connected to the connecting head.

[0010] As a preferred embodiment of this utility model, the movable ring is slidably connected to the connector, the inner wall of the movable ring is symmetrically provided with guide blocks at the front and back, the outer wall of the connector is symmetrically provided with guide grooves at the front and back, the guide blocks are adapted to the guide grooves, and the guide blocks are slidably connected to the guide grooves.

[0011] Through the above technical solution, the guide groove and guide block can limit the movement of the moving ring, making the moving ring more stable when moving.

[0012] As a preferred embodiment of this utility model, the first limiting rod and the second limiting rod are respectively adapted to the first limiting hole and the second limiting hole. The fixing ring is provided with a threaded hole corresponding to the pulling rod. The left side of the outer wall of the pulling rod is provided with an external thread, which is adapted to the threaded hole. The right end of the pulling rod is provided with a pulling button, and the outer wall of the pulling button is uniformly provided with anti-slip texture.

[0013] Through the above technical solution, the anti-slip texture increases the friction with the hand, making it more stable when rotating.

[0014] Compared with the prior art, the beneficial effects of this utility model are: In this invention, a limiting component is installed on the high-sealing pneumatic pipe joint. During connection, the pulling button drives the pulling rod to the right, and the pulled rod is fixed by the external thread. The connecting cap is rotated to connect with the threaded pipe. After the pulling rod is loosened, the first and second fixed springs drive the first and second limiting rods into the first and second limiting holes respectively. Thus, when the connecting pipe is connected to the connector, it can be limited, preventing the threaded connection from loosening under vibration, thus improving its sealing performance. The overall device has a simple structure, is easy to operate, and is more practical. Attached Figure Description

The connecting cap 3 and the threaded tube 4 are threadedly connected. The connecting cap 3 and the threaded tube 4 can be connected through the thread.

[0021] The connector 3 has a first sealing gasket on its right end and a second sealing gasket on its left end. The first sealing gasket is made of fluororubber and the second sealing gasket is made of silicone rubber. Fluororubber has excellent high temperature resistance, oil resistance and chemical corrosion resistance, while silicone rubber has good elasticity and sealing performance. The first and second sealing gaskets can make its sealing performance better.

[0022] The limiting ring 501 is located on the outer wall of the connecting cap 3 and is fixedly connected to the connecting cap 3. The moving ring 504 and the fixed ring 507 are both located on the outer wall of the connector 2. The fixed ring 507 is fixedly connected to the connector 2, and the moving ring 504 is slidably connected to the connector 2.

[0024] The working process of this utility model is as follows: When using the high-sealing pneumatic pipe connector designed in this scheme, during connection, first pull the pull button to the right. When the pull button moves to the right, it drives the pull rod 508 to move to the right. When the pull rod 508 moves to the right, it drives the moving ring 504 to move to the right. When the external thread on the outer wall of the pull rod 508 moves to the left side of the fixed ring 507, rotate the pull button. The pull button drives the pull rod 508 to rotate, thereby limiting the moved moving ring 504. Then, the connecting pipe 1 and the threaded pipe 4 are rotated to connect them. After connecting them, rotate the pull button in the opposite direction, so that the external thread on the outer wall of the pull rod 508 moves to the outside of the threaded hole. Under the action of the first fixed spring 509 and the second fixed spring 510, the first limiting rod 505 and the second limiting rod 506 respectively enter the interior of the first limiting hole 502 and the second limiting hole 503, thereby limiting the connecting pipe 1 and the connector 2, preventing the threaded connection from loosening under vibration environment, and making its sealing performance higher.
