Connection structure of plastic pipe fitting and hula hoop using connection structure

Abstract

The invention discloses a connection structure of a plastic pipe fitting and a hula hoop using the connection structure. The connection structure comprises a hollow plastic pipe fitting body. The connection structure is characterized in that the back end of the plastic pipe fitting body is a locking end; a locking through hole is formed in the locking end; a hollow connecting pipe is arranged at the front end of the plastic pipe fitting body in an integral extension manner; the connecting pipe is inserted in the locking end; a spring piece is integrally arranged on the connecting pipe; the spring piece comprises a fixed end and a free end; the fixed end is fixedly arranged on the connecting pipe; the vertical distance from the free end to the front end surface of the plastic pipe fitting body is smaller than that from the fixed end to the front end surface of the plastic pipe fitting body; and an upwards raised lock catch matched with the locking through hole and corresponding to the locking through hole in position is integrally arranged on the outer surface of the spring piece. The connection structure has the advantages of simple structure, low production cost, high production efficiency, firmness for locking and convenience for dismounting and mounting.

Description

technical field [0001] The invention relates to the field of connection of pipe fittings, in particular to a connection structure of plastic pipe fittings and a hula hoop using the connection structure. Background technique [0002] At present, the common connection methods of plastic pipe fittings generally include two types. One is that the two pipe fittings are connected through mutually matching internal and external threads. Although this connection structure is simple, it needs to be connected between the two pipe fittings after the pipe The connection ends tap the internal thread and the external thread respectively, and there are many manufacturing steps, which makes the production efficiency low; The two pipe fittings are connected together by mutual cooperation. In this connection structure, a return spring for resetting the lock needs to be installed inside the pipe with the lock. The lock and return spring are small in size and generally require manual assembly. ...

[0002] At present, the common connection methods of plastic pipe fittings generally include two types. One is that the two pipe fittings are connected through mutually matching internal and external threads. Although this connection structure is simple, it needs to be connected between the two pipe fittings after the pipe The connection ends tap the internal thread and the external thread respectively, and there are many manufacturing steps, which makes the production efficiency low; The two pipe fittings are connected together by mutual cooperation. In this connection structure, a return spring for resetting the lock needs to be installed inside the pipe with the lock. The lock and return spring are small in size and generally require manual assembly. To the pipe fittings, this makes manual assembly costly and inefficient. In addition, return springs and locks need to be purchased additionally, which makes the cost of materials higher, which in turn leads to higher production costs of the entire pipe fittings
