Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1-5, a hydraulic pipe fitting anti-disengaging structure, including a hydraulic pressure pipe 1, no. two hydraulic pressure pipe 2, be connected with cutting ferrule 3 on the hydraulic pressure pipe 1, when a hydraulic pressure pipe 1 corresponds with No. two hydraulic pressure pipe 2, threaded connection is on No. two hydraulic pressure pipe 2 on the one end of cutting ferrule 3 is followed a hydraulic pressure pipe 1, and bolted connection has plug bush 4 on No. two hydraulic pressure pipe 2, when plug bush 4 rotated to the direction of a hydraulic pressure pipe 1, plug bush 4 threaded connection was on cutting ferrule 3.

In the specific embodiment, the plug bush 4 is connected with the plug rod 5, the plug rod 5 is connected with the spring fastener 6, the cutting sleeve 3 is provided with an opening, and when the plug rod 5 penetrates through the plug bush 4 to be inserted into the cutting sleeve 3, the spring fastener 6 is inserted into the opening.

In the implementation process, the cutting sleeve 3 is provided with a cavity communicated with the opening for the insertion rod 5 to extend into, and the spring buckle 6 extends out of the opening.

In the specific embodiment, a bayonet is arranged on the inner wall of one end of the plug bush 4, and a sealing ring 7 is inserted into the bayonet.

In the implementation process, the sealing ring 7 is connected with a convex block matched with the bayonet, and the sealing ring 7 is inserted into the bayonet through the convex block.

The theory of operation, cutting ferrule 3 threaded connection is first in the one end of a hydraulic pressure pipe 1, plug bush 4 threaded connection is on No. two hydraulic pressure pipe 2, align back hydraulic pressure pipe 1 and No. two hydraulic pressure pipe 2 first, then the cutting ferrule 3 rotates, make the both ends of cutting ferrule 3 connect respectively on a hydraulic pressure pipe 1 and No. two hydraulic pressure pipe 2, insert the lug on sealing washer 7 in the bayonet socket in the plug bush 4, prevent that plug bush 4 from coming off when next rotating in cutting ferrule 3, then the extrusion leads to sealing washer 7 to sink into the screw thread between cutting ferrule 3 and plug bush 4 and stir and finally damage together, then at rotation plug bush 4, make the tip of plug bush 4 stretch into in the cutting ferrule 3 and threaded connection on cutting ferrule 3 (refer to still seted up a cavity on cutting ferrule 3, be used for plug bush 4 threaded connection in the cavity, as shown in fig. 3), in order to improve structural stability, insert in plug stem 5 inserts in plug bush 4, make plug stem 5 pass in plug bush 4 stretch into in cutting ferrule 3, when spring 6 corresponds to the opening, spring 6 stretches out from the opening reversal, prevent plug bush 4 from coming off on 3.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
