Embodiment 1

[0040] See attached Figure 1-10 As shown, a quick connection structure of pipe fittings, the outer pipe fittings and the inner pipe fittings are plugged and positioned through the connecting parts. The connecting parts include a sleeve 1 and an annular spring part 2 with one end open, and the open end of the spring part 2 faces inward. Bending to form a pair of plugs 5; the sleeve 1 is sleeved and fixed on the upper end of the inner pipe 3, and both the inner pipe 3 and the sleeve 1 are inserted into the inside of the outer pipe 6; a pair of through holes 4 are provided on the outer pipe 6 At least one groove is provided on the side wall of the casing 1 corresponding to the corresponding position of the through hole 4; the pair of plugs 5 of the spring member 2 are inserted into the pair of through holes 4 of the outer pipe member 6 , and the spring member 2 has at least two stable states when it rotates around the through hole 4 of the outer pipe member, forming two working ...

Embodiment 2

[0048] See attached Figure 11-12 As shown, a quick connection structure for pipe fittings, the outer pipe fittings and the inner pipe fittings are connected and positioned through the connecting piece. For the plug 5; a pair of through holes 4 are provided on the outer pipe member 6, and two openings are provided at corresponding positions corresponding to the through holes 4 on the inner pipe member 3 plugged into the outer pipe member; one of the spring members 2 The pair of plugs 5 are inserted into a pair of through holes 4 of the outer pipe member 6, and the spring member 2 has at least two stable states when rotating around the through hole 4 of the outer pipe member, forming two working positions:

[0049] (1) Locking position: the two plugs 5 of the spring member 2 pass through the through holes of the outer pipe member and are stuck in the opening of the inner pipe member; the distance between the two plugs of the spring member is less than the opening of the inner p...

Abstract

The invention discloses a rapid connecting structure of a pipe fitting, which is connected in a plugging way by an outer pipe fitting and an inner pipe fitting and is connected and fixed through a connecting piece; the connecting piece comprises a casing pipe and a ring-shaped spring piece with an opening at one side; the opening end of the spring piece bends inward to form a pair of plugs; the casing pipe is sheathed and fixed on the upper end part of the inner pipe fitting; the inner pipe fitting and the casing pipe are both connected to the inner part of the outer pipe fitting in a plugging way; a pair of through holes are arranged on the outer pipe fitting; at least one groove is arranged at the relevant position corresponding to the through holes on the side wall of the casing pipe; a pair of plugs of the spring piece are arranged in a pair of through holes of the outer pipe fitting in a plugging way; when the spring piece rotates around the through hole of the outer pipe fittings, at least two stabilizing states exist to form two work positions; the work positions are locked and unlocked. The invention adopts a combined structure of the casing pipe and the spring piece, realizing rapid locking and disassembling between pipe fittings, therefore, the invention is convenient, safe and reliable in use and has realistic positive meanings.

Description

technical field [0001] The invention relates to a connection structure of metal pipe fittings, in particular to a quick connection structure of pipe fittings, which can realize fast locking and disassembly of pipe fittings. Background technique [0002] In the assembly process of pipe fittings, the pipe connection structure is an essential part, which is used to connect two pipes together. The existing connecting structures mainly include welding or threaded connecting structures. However, for some occasions that need to be quickly locked and disassembled, such as the folding handlebar of a folding bicycle, a more convenient quick-connecting structure for pipe fittings is required. [0003] There are many quick connection structures for pipe fittings. For example, the Chinese utility model patent CN2937598Y discloses a pipe fitting fixing structure, which includes two symmetrical arc-shaped blocks. An arc surface is formed inside the two arc-shaped blocks. One end extends o...
