Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment: a check valve convenient for fast assembly comprises a main body tube 6, wherein two ends of the outer side of the main body tube 6 are symmetrically provided with a first mounting ring 3, the position of the first mounting ring 3, which is far away from the non-circle center of one end of the main body tube 6, is provided with four groups of arc-shaped fixing grooves 15, one end of the first mounting ring 3, which is far away from the main body tube 6, is provided with a second mounting ring 4 matched with the first mounting ring 3, the edge position of the second mounting ring 4, which is close to one end of the first mounting ring 3, is provided with four groups of fixing pins 5 matched with the arc-shaped fixing grooves 15, the middle position of the top of the main body tube 6 is provided with a mounting tube 8, the top of the mounting tube 8 is provided with a valve cover 2, the edge position of the top of the valve cover 2 is provided with a fixing bolt 9 through a thread, the valve cover 2 is fixedly connected with the mounting tube 8 through the fixing bolt, the central point at 1 top of internal thread lid puts the department and is provided with movable rod 11, the bottom of movable rod 11 is passed valve gap 2 and is extended to the inside of installation pipe 8, limiting plate 17 is installed to the intermediate position department in the movable rod 11 outside, the top cover in the movable rod 11 outside is equipped with spring 7, and the bottom of spring 7 and the top fixed connection of limiting plate 17, the bottom of the inboard one end of installation pipe 8 articulates there is installation pole 13, the one end of installation pole 13 is provided with rubber valve clack 14, the bottom of movable rod 11 is provided with the wheel 12 that rolls that mutually supports with installation pole 13.

In this implementation, the top symmetry at the inside both ends of installing tube 8 is provided with installing support 20, and the one end that installing support 20 is close to spring 7 is provided with the spacing wheel 21 of mutually supporting with movable rod 11, helps improving the stability of movable rod 11 lift in-process.

In this embodiment, the rubber plate 16 is disposed at the bottom of the inner side of the valve cap 2, and the annular protrusion 22 cooperating with the rubber plate 16 is disposed at the top of the inner side of the mounting tube 8, which helps to improve the sealing performance at the joint between the valve cap 2 and the mounting tube 8 and prevent water or air from leaking out of the gap at the joint between the valve cap 2 and the mounting tube 8.

In this implementation, the bottom of valve gap 2 is provided with annular splice 18, and the bottom of installation pipe 8 is provided with the annular splice 19 of mutually supporting with annular splice 18, and the inside of annular splice 19 is provided with annular rubber pad, helps further improving the leakproofness of junction between valve gap 2 and the installation pipe 8.

In this implementation, the first mounting ring 3 and the second mounting ring 4 are symmetrically provided with annular grooves at positions close to a non-center of a circle at one end, and a sealing ring is arranged in a group of annular grooves, which is helpful for improving the sealing performance of the joint between the first mounting ring 3 and the second mounting ring 4.

In this embodiment, the outer sides of the internal thread cover 1 and the second mounting ring 4 are both provided with anti-slip threads, so that a user can manually rotate the internal thread cover 1 and the second mounting ring 4.

The working principle is as follows: before use, the two ends of the second mounting ring 4 are communicated with the two ends of the corresponding water pipe, then the fixing pin 5 is gradually extruded and rotated after the fixing pin 4 is held by hands and the outer side of the second mounting ring 4 is inserted into the arc-shaped fixing groove 15, the ball body on the top of the fixing pin 5 passes through the arc-shaped fixing groove 15 and then is tightly attached to the other side of the first mounting ring 3, so that the first mounting ring 3 and the second mounting ring 4 are fixed with each other, according to the actual water pressure condition, when the pressure of the rubber valve clack 14 on the water pressure needs to be enhanced, the internal thread cover 1 is rotated clockwise to descend, so that the stress of the spring 7 is shortened and some elastic potential energy is stored, so that the movable lever 11 is subjected to the downward force exerted by the spring 7, causing the rolling wheel 12 to exert a greater force against the mounting lever 13, where a greater water pressure is required to open the rubber flap 14, when the pressure of the rubber valve clack 14 on water pressure needs to be reduced, the internal thread cover 1 only needs to be rotated anticlockwise.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
