The embodiment of the invention relates to a check valve. The check valve comprises a valve sleeve and a valve body. The valve sleeve comprises a valve sleeve body, a valve sleeve clamping groove, a limiting ring, valve sleeve sealing grooves and first sealing rings, wherein the valve sleeve clamping groove is formed in the inner side wall of the valve sleeve body, the limiting ring is located on the inner side wall of the portion in front of the valve sleeve clamping groove, the valve sleeve sealing grooves are formed in the two ends of the valve sleeve, and the first sealing rings are held in the valve sleeve sealing grooves. The valve body comprises a locating ring, a second sealing ring, a blocking piece, valve body clamping sleeves and a valve element. The locating ring abuts against the inner side of the limiting ring, a first groove is formed in the top of the locating ring, and a second groove is formed in the inner side of the locating ring. The second sealing ring is held in the first groove of the locating ring. The blocking piece comprises a through hole and is inserted into the second groove in a connected mode. The valve body clamping sleeves are located on the inner side of the blocking piece and abut against buckle rings on the outer side walls of the valve body clamping sleeves. The valve element comprises a first connecting portion, a second connecting portion and a spring. The first connecting portion comprises an abutting portion and a first connecting rod, wherein the abutting portion abuts against the through hole of the blocking piece. The second connecting portion comprises a fixing rod and a second connecting rod, wherein the fixing rod and the second connecting rod are connected with each other, the fixing rod and the valve body clamping sleeves are fixed, and the second connecting rod sleeves the first connecting rod in a connected mode. The spring sleeves the outer side of the second connecting rod in a connected mode.

The invention discloses a spiral locking device, which comprises a spiral body and a spiral fixing cap, wherein the spiral body is fixedly arranged on an electric plug connector or an electric plug connector female seat, a buckling groove is formed in the spiral body, the spiral fixing cap can be inserted into the spiral body in a rotating mode and is provided with a lock catch part capable of being locked into the buckling groove, the buckling groove comprises a strip-shaped groove body obliquely arranged along the side wall of the spiral body, a groove body opening formed along the edge of the spiral body is formed in one end of the strip-shaped groove body, and a locking structure used for locking the lock catch part is arranged at the other end of the strip-shaped groove body. According to the spiral locking device, rapid disassembly and assembly of cable connection are achieved, the problems that a threaded fastening structure is complex in installation and long in consumed time are solved, and the installation cost is greatly saved.
