The inner walls of the clamp upper cover and the clamp lower cover press on the sealing ring to achieve compression sealing. This design has the advantages of simple structure, low production cost, high stability, etc.

[0003] However, since the upper cover and the lower cover of the clamp are not connected, it will increase the difficulty of installation, especially when the installation conditions are not good. The clamp is connected with bolts, which is cumbersome to install, time-consuming, and increases the construction cost. The clamp is directly used to press the sealing ring. Since the clamp is subjected to pulling force, it will shift slightly under high pressure, which may cause leakage.

[0004] Therefore, how to solve the above problems has become an issue that needs to be addressed urgently. Summary of the invention

[0005] In view of the above technical problems, the present invention provides a ratchet clamp pipe quick-release connector, which adopts a tooth buckle design, is easy to install, and automatically locks, effectively reducing the operation time and difficulty of on-site construction. The clamp upper cover and the clamp lower cover are hingedly connected by pins, and can be opened and closed with the pins as the axis, which is convenient for on-site construction and installation. The clamp produces a seal by compressing the sealing ring protective sleeve, and the sealing performance is better. When disassembling, you only need to disengage the rack to open the closed clamp, which is convenient for disassembly. The structure is compact, the performance is stable, and the on-site operation efficiency is quickly improved.

[0006] To achieve the above object, the technical solution of the present invention is:

There are two ratchet bars, which are respectively hinged in the U-shaped opening of the ratchet seat, and the ratchet bar has a plurality of buckle teeth; ratchet recesses are provided on both sides of the hoop upper cover, and a plurality of ratchet holes are provided in the ratchet recesses; the ratchet spring is buckled between the ratchet seat and the ratchet bar in a compressed state, and the buckle teeth of the ratchet bar are compressed in the ratchet holes. The hoop concave ring increases the strength of the hoop lower cover, is conducive to the welding and fixing of the ratchet seat, and is convenient for installation. The ratchet bar is hinged in the U-shaped ratchet seat opening, and is automatically elastically compressed by the ratchet spring, which has a simple structure and is easy to operate.

[0012] The sealing structure further includes a rubber sealing sleeve and a sealing ring protective sleeve, and the sealing ring protective sleeve is composed of two identical halves; the rubber sealing sleeve is sleeved on the pipe, and the sealing ring protective sleeve is sleeved on the rubber sealing sleeve. Through the tensioning structure, the upper cover and the lower cover of the clamp are closed and the rubber sealing sleeve is continuously squeezed.

Since the tooth spring presses the ratchet bar, during the closing process, the rack bar is continuously buckled into the ratchet hole on the upper cover of the clamp, and a sound of "clicking" is continuously emitted. The upper cover and the lower cover of the clamp can be hingedly connected by pins. When installing, you only need to open the clamp and close it on the pipe. The rack bar automatically buckles in one direction. Once buckled, it cannot be disengaged, which is convenient and quick.
