Abstract
The utility model discloses a quick-change connector and relates to the quick-change connector in the field of connectors. The quick-change connector is low in production cost. According to the technical scheme, the quick-change connector comprises a male connector body, a valve arranged in a through hole in the male connector body in a sleeved mode, a spring and a spring base. The quick-change connector is characterized in that a groove is formed in the position, where the spring base is arranged, of the inner wall of the through hole in the male connector body, and a check ring for locating the spring base is arranged in the groove. The quick-change connector has the advantages that an original wire drawing spring is replaced by the standard part check ring which is convenient to purchase, machine and produce and low in production cost; the check ring is adopted to locate the spring base, so the spring base can be more conveniently and quickly installed and dismantled; the valve is attached to the male connector body through conical surfaces, so the contact area between the valve and the male connector body is increased, and sealing is reliable.
Description
Technical field
The utility model relates to joint field, is specifically related to a kind of quick release coupling.
Background technique
Quick release coupling is a kind of two cut-off joint, because it can be down to flow losses and minimumly be widely used in the fields such as vehicle, Architectural Equipment, machinery, chemical industry equipment in the time disconnecting, thereby can carry out equipment operating or safeguard for fluid circuit well time, provide the situation of its required connection or disconnection.Existing quick release coupling is made up of male connector and the negative joint two-part all with cutoff function, male connector and the negative joint main check valve that uses in seal form carries out conical surface seal under the effect of spring, and spring action is on spring seat, and spring seat is by stay spring location.When docking, dock compression by the valve assembly of male connector and the valve assembly of negative joint valve passage is opened, realize pipe passage and be communicated with.When separation, male connector and negative joint valve assembly separately blocks spring seat by stay spring, and valve seals conical surface hole gradually under the effect of spring.Because spring seat positions by stay spring, and stay spring is non-standard component, cannot directly buy and obtain, and stay spring is difficult for processing, and cost of production is higher, is more not easy to install and disassemble.
Summary of the invention
The quick release coupling that provides a kind of cost of production low is provided the purpose of this utility model.
For achieving the above object, the technical solution of the utility model is:
A kind of quick release coupling, comprises male connector and is set in valve, spring and the spring seat in male connector through hole, it is characterized in that: the male connector through-hole wall at spring seat rigging position place offers groove, is provided with the back-up ring for positioning ejection spring abutment in groove.
Further, between spring seat and back-up ring, be provided with packing ring, on the conical surface of valve front end and male connector through-hole wall joint place, be provided with sealing gasket.
The beneficial effects of the utility model are:
1, original stay spring is replaced by standard piece back-up ring, is convenient to buy, be convenient to processing, cost of production is low; Adopt back-up ring to position spring seat, the installation of spring seat, disassemble convenient, quick; Between valve and male connector, fit by conical surface, increased area of contact between the two, sealing is reliable.
2, due to the reasons in structure of spring seat, between spring seat and back-up ring, set up packing ring, can effectively position spring seat, on valve, be connected with sealing gasket, make to seal between valve and male connector more reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of male connector in the utility model;
Wherein reference character is: 1-male connector, 2-valve, 3-spring, 4-spring seat, 5-back-up ring, 6-packing ring, 7-sealing gasket.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, a kind of quick release coupling, comprises male connector 1, valve 2, spring 3 and spring seat 4.On spring seat 4 suits and valve 2, between valve 2 and spring seat 4, can mutually move.Spring 3 is between valve 2 and spring seat 4, and valve 2 compresses or stretches with spring seat 4 spring 3 in the time mutually moving.After valve 2, spring 3 and spring seat 4 are assembled, integral assembling is in the through hole of male connector 1.Male connector 1 through-hole wall at spring seat rigging position place offers groove, is provided with the back-up ring 5 for positioning ejection spring abutment 4 in this groove.Under the spring-force driven dual of spring 3, the conical surface of valve 2 front ends and male connector 1 through hole conical surface inwall laminating, stop flow losses, in the time that negative joint docks with male connector 1, the stressed Compress Spring 3 of valve 2, conical surface bonded to each other is separated from each other, and is communicated with negative joint and male connector 1.
In addition, also can between back-up ring 5 and spring seat 4, add packing ring 6, on the conical surface of valve 2 front ends and male connector 1 through-hole wall joint place, be provided with sealing gasket 7.
In the time that male connector docks with the valve of negative joint, the positioning action to spring seat due to back-up ring and packing ring, makes valve Compress Spring, thereby opens circulation passage.In the time that male connector separates with negative joint valve, the conical surface inwall laminating of the conical surface of valve front end and male connector 1 through hole, valve seals conical surface hole under the effect of spring, stops flow losses.
Claims (2)
1. a quick release coupling, comprise male connector (1) and be set in valve (2), spring (3) and the spring seat (4) in male connector through hole, it is characterized in that: male connector (1) through-hole wall at spring seat (4) rigging position place offers groove, is provided with the back-up ring (5) for positioning ejection spring abutment (4) in groove.
2. a kind of quick release coupling as claimed in claim 1, is characterized in that: between spring seat (4) and back-up ring (5), be provided with packing ring (6), on the conical surface of valve (2) front end and male connector (1) through-hole wall joint place, be provided with sealing gasket (7).
