Quick coupling structure

Abstract

The invention discloses a quick coupling structure. The quick coupling structure comprises a coupling body capable of allowing an insertion pipe to be inserted, wherein a fixed seat is connected to the coupling body; an elastic clamping part capable of clamping the insertion pipe after the insertion pipe is inserted into the coupling body is arranged on the fixed seat; a housing sleeves the fixedseat; a first projection part capable of jacking the elastic clamping part to enable the elastic clamping part to tightly clamp the insertion pipe when the housing is located at an initial position isarranged on the inner wall of the housing; a first elastic sheet capable of rebounding the housing after sliding relative to the fixed seat back to the initial position is arranged on the fixed seat;and a second projection part capable of forming slide fit with the first elastic sheet is arranged on the inner wall of the housing. According to the quick coupling structure disclosed by the invention, the first elastic sheet is used for replacing an original spring structure, and rapid rebounding for the housing can be realized after the housing slides, so that the cost is saved; moreover, theupper end of the first elastic sheet is arranged in a manner of being bent towards the inner side, and used cooperatively with the housing, so that breakage due to long-time use is avoided; and the quick coupling structure is reasonable in design and capable of prolonging the service life.

Description

【Technical field】 [0001] The invention relates to a quick connector structure. 【Background technique】 [0002] In the fields of garden watering, car washing spray, cleaning spray, etc., it is necessary to connect through long-distance water pipes. One end of the water pipe is connected to a water supply structure that can supply water sources such as a faucet, and the other end of the water pipe is connected to a water spray such as a water gun. Structurally, to achieve long-distance watering or spraying. But as long as the water pipe is slightly pulled, the water pipe will fall off from the faucet. Someone has designed a quick connector structure, one end is connected to the faucet, and the other end is connected to the water pipe to realize the quick connection between the water pipe and the faucet. [0003] However, there are many and complicated quick connector parts on the market. Springs are generally used as the rebound mechanism, which is costly, complicated to asse...

Problems solved by technology

[0003] However, there are many and complicated quick connector parts on the market. Springs are generally used as the rebound mechanism, which is costly, complicated to assemble, and slow in production capacity. Moreover, some rebound mechanisms are unreasonable in design. It is easy to squeeze the rebound mechanism for a long time and multiple times. Break the rebound mechanism, thus losing the rebound function, and the use effect is poor
