Abstract

The utility model relates to a fluid pipe coupling, in particular to a cam lock type quick coupling with self-locking handles. The cam lock type quick coupling with the self-locking handles comprises a male head body and a female head body which are matched with each other in a plug-in way and are hermetically coupled through a sealed flat gasket; two opposite handles are rotationally arranged on the female head body; one end of each handle is of a cam shape; two arc-shaped grooves matched with the cam ends of the handles are arranged oppositely on the male head body; a pin shaft guide rail is arranged on each handle; a self-locking pin shaft capable of reciprocating is arranged in the pin shaft guide rail; a compression spring is arranged between the self-locking pin shaft and the pin shaft guide rail; and a self-locking bayonet lock matched with the self-locking pin shaft for locking the handles is fixedly arranged on the female head body. After the handles are pressed, the self-locking pin shaft and the self-locking bayonet lock are matched to lock the handles automatically, and the handles are prevented from being unlocked due to external force influence; and the cam lock type quick coupling with the self-locking handles is very convenient to use.

Description

A kind of cam lock compact form rapid pipe joint with the self-locking handle

Technical field

The utility model relates to a kind of fluid coupling, relates in particular to a kind of cam lock compact form rapid pipe joint with the self-locking handle.

Background technique

The rapid pipe joint of cam lock compact form is derived from MIL STD, is used for the connection and the disconnection of fluid delivery pipeline, because its dismounting rapid and convenient has been widely used in the FLUID TRANSPORTATION field at present.The rapid pipe joint of cam lock compact form is made up of a female body, a public body, camlock handle assembly and Sealing etc.In use; The arc end of a public body is packed in the endoporus of a female body; (handle is installed between two lugs of a female body to depress the camlock handle then; Each female body need be adorned 2 grip), and in the aperture of female head process ear, insert safety pin, to prevent that two handles are thrown off voluntarily under external force.This method of after the handle pressing, inserting safety pin has increased the workload of using the workman.

The model utility content

The utility model provides a kind of cam lock compact form rapid pipe joint with the self-locking handle, can automatically lock after the handle pressing, and is easy to use.In order to realize the foregoing invention purpose, the utility model has adopted following technological means:

A kind of cam lock compact form rapid pipe joint with the self-locking handle comprises a public affairs body and a female body that mutual grafting cooperates, passes through sealing plain cushion sealing joints between the two; On the said mother body relative to rotate two grip be set, an end of said handle is cam-like; Be oppositely arranged two curve baths that cooperate with the cam end of handle on the said public affairs body; Said handle is provided with the bearing pin guide rail; Be provided with the self-locking bearing pin that can move around in the said bearing pin guide rail; Be provided with pressure spring between said self-locking bearing pin and the bearing pin guide rail; Be set with the self-locking bayonet lock that cooperates locked hand with the self-locking bearing pin on the said mother body.

The end of said self-locking bearing pin is circular-arc in face of a side of self-locking bayonet lock;

The afterbody of said self-locking bearing pin is connected with draw ring;

Said bearing pin guide rail is arranged on the bearing pin cover plate; Said bearing pin cover plate is fixed on the handle.

The beneficial effect of the utility model is: after the handle pressing, self-locking bearing pin and the cooperation of self-locking bayonet lock automatically lock handle, prevent that external force from influencing handle and unclamping, and use very convenient.

Description of drawings

Fig. 1 is the structural representation of a kind of cam lock compact form rapid pipe joint with the self-locking handle of the utility model.

Embodiment

Below in conjunction with accompanying drawing, the preferred implementation of a kind of cam lock compact form rapid pipe joint with the self-locking handle of the utility model is made detailed description:

As shown in Figure 1, this rapid pipe joint mainly comprises a public body 1 and a female body 2, and a public body 1 can insert in the endoporus of a female body 2, is provided with sealing plain cushion 5 between the two, in order to seal the seam between a public body 1 and the female body 2.

Two lugs of arranged outside of a female body 2 are provided with handle 4 through handle pin 3 rotations between two lugs, and handle 4 has two, the relative outside that is arranged on a female body 2.One end of handle 4 is cam-like.The relative curve bath that is provided with two indents in the outside of a public body 1, when a public body 1 inserted in the female body 2, the cam end of handle 4 just in time was trapped in this curve bath.When rotatory handling 4, the cam of handle 4 promotes curve bath and then drives a public body 1 to hold out against a female body 2, thereby realizes that a public body 1 is connected with female the quick of a body 2.

The lug of a female body 2 is provided with self-locking bayonet lock 6, is cylindrical bayonet lock, under its barrier effect, can not continue rotation after the handle 4 thorough pressings.The handle below of handle 4 is with rivet 8 fixed installation bearing pin cover plates 10, and bearing pin cover plate 10 is provided with one section bearing pin guide rail 11, and self-locking bearing pin 7 is installed in the bearing pin guide rail 11, and stretch out outside the bearing pin guide rail 11 top and bottom of self-locking bearing pin 7.Be provided with pressure spring 9 between self-locking bearing pin 7 and the bearing pin guide rail 11, under its effect, the upper end of self-locking bearing pin 7 keeps stretching out outside the bearing pin guide rail 11.

Along with the pressing rotation of handle 4, the upper end of self-locking bearing pin 7 is arranged to circular-arc in face of a side of self-locking bayonet lock 6, and in the process of handle 4 pressings, self-locking bayonet lock 6 can withstand the upper end of self-locking bearing pin 7, makes self-locking bearing pin 7 retractions.

Self-locking bearing pin 7 can be made rectangle, Hexagon etc. with bearing pin guide rail 11, perhaps sets up rectangular boss on the self-locking bearing pin 7, and bearing pin guide rail 11 also is provided with and is corresponding rectangle, thereby prevents that self-locking bearing pin 7 from rotating in bearing pin guide rail 11.

The lower end of self-locking bearing pin 7 is equipped with draw ring 12, thereby convenient pulling self-locking bearing pin 7 is realized the release of handle 4.

When this rapid pipe joint is moved, earlier handle 4 is upwards mixed, then a public body 1 is inserted in the endoporus of a female body 2, the depression of handle 4 of exerting oneself simultaneously, the cam of handle 4 promotes curve bath and then drives a public body 1 to hold out against a female body 2.In the process that presses down handle 4; When the periphery of self-locking bayonet lock 6 is run at the arc surface position of self-locking bearing pin 7; Self-locking bearing pin 7 stressed retractions, when the top, upper end of self-locking bearing pin 7 streak self-locking bayonet lock 6 bottom after, under the effect of pressure spring 9; Self-locking bearing pin 7 is returned to reset condition, realizes self-locking thereby block handle 4.

During disengagement, spur draw ring 12 downwards, the pulling handle 4 that makes progress simultaneously can be accomplished the release of handle 4.

Set up self-locking mechanism on this rapid pipe joint handle 4, realized automatically locking of handle 4, used very convenient.
