Abstract
The utility model relates to a quickly-detachable coupling which comprises a male member valve core, a female member valve core, a small pin roller, a spring, a movable valve body, a handle wheel and a connecting member. The quickly-detachable coupling is characterized in that a special groove in the surface of a male member can be divided into three sections, namely a connecting section, a transitional section and a stopping section. According to the quickly-detachable coupling, due to the adoption of a function integrating idea, the functions of quick connection, medium conical sealing, connecting self-locking and automatic connection and disconnection are integrated and special requirements in special occasions can be met.
Description
Technical field
The present invention relates to a kind ofly can load and unload coupling fast.
Background technique
The general defective that existing coupling exists is that the connector efficient that is threaded is not high.Being threaded generally all has self-locking requirement reliable with what guarantee to connect, thereby its joint efficiency is lower, generally needs to twist quite a few circles.
Summary of the invention
The present invention is in order to solve the problems of the technologies described above; Provide a kind of and can load and unload coupling fast; The technological scheme of taking is: a kind ofly can load and unload coupling fast; Comprise male member spool, recessed spool, little roller, spring and movable valve, handwheel and link, it is characterized in that the spiral chute on male member surface can be divided into 3 sections: linkage section, changeover portion and stopping section.
The effect of stopping section is to make little roller under the effect of spring force, be stuck in stopping section rollback voluntarily; Make male and female member under the effect of the impact force of medium; Can not separate automatically, promptly realize the auto-lock function of coupling, thereby guarantee the reliable connection of coupling when proper functioning.
Changeover portion then be for stopping section and linkage section smooth excessively.Linkage section is the major section of this coupling piece, and its major function is that male and female member is packed into each other, connects.Because this section mainly is in order to connect, not have self-locking requirement, thereby for the rapidity that connects, its lead angle is very big usually.
Use this connector, only need can accomplish connection or dismantlement work, thereby realize the rapid coupling or the disassembling function of joiner with the handwheel rotation less than half-turn.
This coupling that can load and unload has fast adopted the integrated thought of function, rapid coupling, medium cone seal, connect self-locking, on-off function is integrated in one voluntarily, can satisfy the specific demand of special occasions.
Description of drawings
Fig. 1 is a structural drawing of the present invention.
Embodiment
A kind ofly can load and unload coupling fast; The technological scheme of taking is: a kind ofly can load and unload coupling fast; Comprise male member spool 7, recessed spool 8, little roller 6, spring 8 and movable valve 9, handwheel 4 and link, it is characterized in that the spiral chute on male member surface is divided into 3 sections: linkage section, changeover portion and stopping section.Recessed spool is fixing tight through nut collar 1, and be vertically fixing through sunk screw 2.
The realization principle of coupling auto-lock function is: connect in the course of normal operation that finishes at pipeline; Because male member spiral fluted tail end has the stopping section; Little roller is stuck in stopping section rollback voluntarily under the effect of spring force; Make male and female member under the effect of the impact force of flowing medium, can not separate voluntarily, thereby guaranteed the reliability that pipeline connects.
When the completion of connection task needs dismounting, the backward rotation handwheel, this is the spiral chute backscrolling of roller along male member, makes male and female member progressively separate fast along the coupling axis.In the separation process, under the spring force effect, recessed movable valve and male member spool reset gradually; And before male and female member was thrown off fully, valve body and spool restPosed, and combined closely with separately valve body, spool; Seal pipeline port separately, reach and separate the purpose that the back pipeline cuts off automatically.
Claims (1)
1. one kind can be loaded and unloaded coupling fast, comprises male member spool, recessed spool, little roller, spring and movable valve, handwheel and link, it is characterized in that: the spiral chute on male member surface is divided into 3 sections: linkage section, changeover portion and stopping section.
