Abstract
The utility model relates to a flat detent type quick connection joint, comprising a valve body, a valve core assembly and a connection device, wherein the valve body comprises an input end and a connection end; a detent hole is opened at the valve connection end and the connection device is a flat detent; the detent is adaptive with the detent hole of the connection end and slidable in the detent hole to make the detent connected with a component inserted into the valve connection end. The detent is in U shape and arc structures are oppositely arranged on the two side arms and four detent holes are opened on the valve connection end; two detent holes are mutually communicated with each other and the communicated detent holes are crossed with the inner hole of the connection end and mutually symmetric. The flat detent type quick connection joint has the following features: 1 easy process of the flat detent and good precision and consistency; 2 keeping precision and consistency during the heat treatment to prevent extra shaping work; 3 easy installation to obtain very high assembly precision; 4 increased safety and reduced on-off failure due to leakage.
Description
Technical field
The utility model relates to jointing, and especially a kind of novel structure connects reliable flat bail type fast connecting joint.
Background technique
Fast connecting joint is used very extensive in the feedway of fluid.For example, in car hydraulics, fast connecting joint is used for connecting pipeline and pipeline or pipeline and wheel cylinder etc. as the quick connected element of pipeline; In the automobile clutch pipeline, fast connecting joint is located at the input pressure end of clutch slave cylinder, forms a wheel cylinder with butt joint on the automobile and the quick of hydraulic tube is connected, and it greatly facilitates the replacing and the maintenance of product.
At present, above-mentioned this class fast connecting joint generally all is to adopt annular pawl structures, shown in accompanying drawing 5 and accompanying drawing 6, and the 1st, oil pipe, the 2nd, oil intake nozzle, the 4th, valve body, the 5th, Spool assembly, the 6th, annular ratchet.Annular ratchet 6 is difficult to the accuracy and the conformity of control product when processing and heat treatment, even by follow-up extra shaping, still be difficult to return to the preceding shape of heat treatment; Annular ratchet 6 is round structure normally, is difficult to during installation be in place, and influences the validity and the conformity of product.In the using process, because the validity of ratchet heat treatment and assembling does not often reach requirement, ratchet can not be worked good with valve body, causes as consequences such as clutch inefficacies thereby pressure leakages occurs when causing actual entrucking.
The model utility content
At the deficiency of above existing fast connecting joint, the purpose of this utility model provides a kind of novel structure, is difficult for revealing the reliable flat bail type fast connecting joint of attachment security.
The purpose of this utility model is achieved by the following technical solution:
Flat bail type fast connecting joint, comprise valve body, Spool assembly and connection set, valve body comprises input end and connecting end, Spool assembly is located in the valve body, the connecting end of described valve body has pin hole, and described connection set is a bayonet lock, and the pin hole of bayonet lock and valve body connecting end is suitable, bayonet lock can slide in pin hole, makes bayonet lock to form with the member that inserts the valve body connecting end and is connected.
As optimal technical scheme of the present utility model, described bayonet lock is made as the U-shaped structure, be provided with arc-shaped structure on the side arm of bayonet lock both sides relatively, correspondingly on the hole wall of valve body connecting end have four pin holes, respectively have two pin holes to connect mutually in four pin holes, the endoporus of the pin hole of perforation and valve body connecting end intersects and is symmetrical.
As optimal technical scheme of the present utility model, the bayonet lock of described U-shaped structure is made by rubber-like flat metal bar, and the end of bayonet lock two side arms outwards bending makes the opening end of bayonet lock be made as sector structure.
As optimal technical scheme of the present utility model, described flat metal bar is a spring steel.
As optimal technical scheme of the present utility model, be arranged with seal ring on the excircle of described valve body input end, also be provided with seal ring between Spool assembly and the valve body.
With respect to prior art, the utility model has following characteristics:
1. flat bayonet lock is simple in structure, and processing can obtain good validity and homogeneity of product easily;
2. flat bayonet lock still can keep the validity and the conformity of product during heat treatment, thereby avoids extra shaping work;
3. the pancake structure of flat bayonet lock uniqueness makes that its installation is very easy, thereby obtains very high assembling validity and conformity;
4. These characteristics makes Security of the present utility model further improve, and has significantly reduced to occur after the actual entrucking revealing causing the clutch failure phenomenon.
