Abstract
The utility model relates to a hand-wheel type quick-change connector, which includes a female connector, a male connector and non-return valves located in the female connector and the male connector, wherein a ferrule is arranged at the top end of the female connector; a circular movable hand-wheel is arranged on the ferrule, and is fixedly sleeved on the ferrule; a circular fixed hand-wheel is arranged at the rear section of the female connector, and is fixedly sleeved on the female connector and parallels to the movable hand-wheel. According to the hand-wheel type quick-change connector, the movable hand-wheel is arranged on the ferrule, and the fixed hand-wheel is arranged on the female connector, so that the pushing and pulling of the ferrule is facilitated and further the connection and disconnection of the quick-change connector can be realized.
Description
Technical field
The utility model relates to a kind of quick release coupling, is specially a kind of hydraulic pressure quick release coupling that has the big latus rectum of handwheel.
Background technique
Common hydraulic pressure quick release coupling works the lasso outer surface that compresses the steel ball effect and generally adopts reticulate pattern or groove form to increase friction at present, is convenient to the push-and-pull lasso and realizes connecting and breaking off quick release coupling; (inside nominal diameter＞DN50) the hydraulic pressure quick release coupling is bigger because of volume, is difficult for pulling, and O-ring seals surface friction drag was bigger when male connector inserted negative joint, and this causes difficulty just for the connection or the disconnection of hydraulic pressure quick release coupling for big latus rectum.
Summary of the invention
The utility model provides a kind of hand-wheel-type quick release coupling, has solved the shortcoming that existing big latus rectum quick release coupling connects or disconnection is comparatively difficult.
Realize that the technological scheme that the utility model above-mentioned purpose is adopted is:
A kind of hand-wheel-type quick release coupling; At least comprise negative joint, male connector and be positioned at negative joint and the one-way valve of male connector; The top of negative joint is a lasso, and lasso is provided with the movable handwheel of ring-type, and movable handwheel fixed cover is loaded on the lasso; The back segment of negative joint is provided with the fixedly handwheel of ring-type, and fixedly the handwheel fixed cover is loaded on the negative joint and is parallel with movable handwheel.
Described movable handwheel and fixedly handwheel be circular, and both are all vertical with negative joint.Movable handwheel is positioned at the tail end of lasso.
Described movable handwheel and fixedly handwheel form by spoke and outer rim, outer rim is the closed circle ring-type and is fixed on lasso and the negative joint through spoke.
The external diameter of the external diameter of described movable handwheel and fixing handwheel is identical.
The hand-wheel-type quick release coupling that the utility model provides has following advantage: this hand-wheel-type quick release coupling; With plaing a movable handwheel is set on the lasso that compresses the steel ball effect; In addition a fixedly handwheel is set on negative joint, thereby makes things convenient for the push-and-pull lasso to realize the connection and the disconnection of quick release coupling.
Description of drawings
The structural representation of the hand-wheel-type quick release coupling that Fig. 1 provides for the utility model;
Among the figure, the 1-male connector, the 2-wire circlip, the 3-steel ball, the 4-lasso, the 5-spring, the movable handwheel of 6-, the 7-one-way valve, 8-O shape seal ring, 9-is handwheel fixedly, and the 10-valve is used spring, 11-valve seat, 12-negative joint.
Embodiment
The utility model is done bright in detail specifically below in conjunction with accompanying drawing.
The structure of the hand-wheel-type quick release coupling that the utility model provides is as shown in Figure 1, by negative joint 12, male connector 1 and lay respectively at negative joint 12 and male connector 1 in one-way valve 7 form, one-way valve 7 is fixed in the moon/male connector through valve seat 11.One-way valve 7 is provided with O-ring seals 8, and under the situation that negative joint and male connector break off, O-ring seals 8 closely contacts the closure of realization the moon/male connector with the outlet of inner conical on the moon/male connector under the elastic force effect of the valve on the one-way valve 7 with spring 10.
The top of negative joint 12 is a lasso 4, and lasso 4 is fixed on the negative joint 12 through wire circlip 2, and lasso 4 has steel ball 3, and when negative joint was connected with male connector, steel ball 3 snapped in the V-shaped groove on the male connector 1, and male connector can't be withdrawed from negative joint.Lasso also is provided with spring 54 times, is used for preventing lasso 4 random play on negative joint.
Lasso 4 is provided with the movable handwheel 6 of ring-type, and movable handwheel 6 fixed covers are loaded on the lasso 4, and are positioned at the tail end of lasso 4.The back segment of negative joint 12 is provided with the fixedly handwheel 9 of ring-type, and fixedly handwheel 9 fixed covers are loaded on the negative joint 12 and are parallel with movable handwheel 6.Movable handwheel 6 and fixing handwheel 9 are circular in the present embodiment, and both are all vertical with negative joint.The external diameter of the external diameter of movable handwheel 6 and fixing handwheel 9 is identical, and by spoke and outer rim composition, and outer rim is the closed circle ring-type and is fixed on the negative joint through spoke.
The working principle of the hand-wheel-type quick release coupling that the utility model provides is following: when needs broke off negative joint and male connector, both hands were held movable handwheel and fixing handwheel, and movable handwheel is moved backward; Length of spring compressed, steel ball jack-up, reach the limit of the position after; The male connector of hand-wheel-type quick release coupling at valve with under spring action and the manual tension; In negative joint, deviate from, realize the disconnection of joint, one-way valve is closed with under the acting force of the spring at valve voluntarily simultaneously; Anti-fluid outflow works the effect of damming.With above-mentioned same method, male connector is inserted in the negative joint, unclamp fixedly handwheel, promotion activity handwheel forward, reach the limit of the position after, compress steel ball, one-way valve is retreated simultaneously, opens fluid passage, realizes the connection of quick release coupling, and connects the pipeline fluid.
