Description

Fastening structure is strengthened in rapid pipe joint

The utility model relates to a kind of joint structure, specifically is meant energy reinforced joint join strength, and fastening structure is strengthened in the rapid pipe joint that joint is difficult for getting loose during fastening.

At present the joint structure that uses is to utilize two relative joints with the mutual fit of interlock mode, utilizes a simple buckle to be fixed, though save time, careless because of using in use, cause the joint clamping part to get loose, cause transported substance to leak outside; Of a specified duration slightly when service life, wearing and tearing are easily caused in the buckle part, form state built on the sand during buckle, get loose at last in the same old way; Not enough driving fit during latch closure forms the state that gets loose in the same old way.

The purpose of this utility model provides the dual solid lock of a kind of joint that joins, and avoids that pipeline gets loose when transmission, dismounting and more ring change rapid pipe joint quickly and easily strengthen fastening structure.

Design proposal of the present utility model is, it mainly comprises a body, a slide fastener portion and C shape ring, utilize the mutual fit of opposing tabs body, the rotation of the slide fastener portion of utilization itself slips in the draw-in groove of body and the formation of engaging body button hook place again, to detain handle admittedly at last and press down, the trip on the solid button handle is inserted among the notch of body.

Below in conjunction with accompanying drawing the utility model is described in detail.

Embodiment:

Referring to Fig. 1, main body view for existing joint structure, main composition is a body (10), extend two relative button hook (11) and button hooks (12) at body (10) front end, and in conjunction with the time form groove, one ring-type element (13), be sleeved on body (10) and upward also can do spinning movement, there is the card tip (131) (the relative position card tip (132)) of outstanding shape the symmetry both sides, when joint joins, with vertical mode with front end button hook (11), (12) put mutually, then utilize ring-type element (13), make the card tip (131) of outstanding shape in conjunction with rotation, (132) can insert among the groove of formation fast; But on the connector engages structure, fastening the position, only utilizing the card tip (131), (132) fixing, the tightness deficiency, no matter and on the personnel operation, cause in the fastening structure wearing and tearing service life, all meet accident easily.

Referring to Fig. 2, slide fastener portion of the present utility model (20) is an annular, is socketed on the body (30), can do rotational slide, has one to detain handle (21) admittedly on it, is connected with slide fastener portion (20) by axial region (211).When not using usually, no matter detaining handle (21) and body admittedly becomes perpendicular or parallel shape and all can not influence to some extent, nationality is moving by front end axial region (211) and handbar (212) upper and lower plates, the operation simple light, be tied to form a flexuose and detain trip (213) admittedly, when inserting the notch of body downwards, aim at notch easily through hollow out place (22); It is different to be provided with width in the leading edge end

Shape card article (23), in the time of can utilizing connector engages, rotation is inserted in the hiding groove of button hook inside.

Referring to Fig. 3, joint body (30) provides a level and smooth slide rail (31), ring-type slide fastener portion (20) can be overlapped receive outside it, and use the solid lock of C shape ring (40) by the recessed rail in rear place (32). make slide fastener portion (20) go up rotational slide at joint body (30). the front end extended spot is provided with two reverse button hooks (33) and reverse button hook (34).And outstanding buckle inner wall (331) and the variable thickness sample of buckle inner wall (341) own, so oppositely button hook (33,34) inside can be produced with the system that is interlocked

Shape is hidden draw-in groove (50); The rear end is around locating and be provided with several notches (35).For detaining handle (21) when pressing down admittedly, solid button trip (213) is inserted in one of them notch of below (35).

Referring to Fig. 4. utilize the solid lock of C shape ring (40), make slide fastener portion (20) on joint body (30), do spinning movement, an elastic washer (36) is set in the joint, increase the adaptation of jointing when fastening.

Referring to Fig. 5, the utility model is when engaging, outstanding reverse button hook (33) and reverse button hook (34) are inserted in the position that the other side does not have reverse button hook, relatively the reverse button hook (33a) given prominence to of the other side and reverse button hook (34a) also trap go into the position that body does not have reverse button hook, between the other side's button hook (34a) and body (30), promptly form one

Shape draw-in groove (50), remaining part is also identical.When rotating slide fastener portion (20), Shape card article (23) can progress into

In the shape draw-in groove (50), till the buckle that contradicts each other.Then will detain handle (21) admittedly and press down, and make solid button trip (213) insert body (30) downwards and go up in the notch (35) that is provided with, promptly finish connecting moves.

The utility model uses operation by human hand to detain handle (21) easily admittedly, can save strength during operation, and handle under the plate can be stablized solid button easily; Stability when reinforced joint fastens needn't be worried in the past to cause the joint clamping part to get loose because rock or uses accidentally in the external world, and the situation that transported substance is leaked outside takes place; Even year is caused the consumption of article for a long time, direct replacing can be pulled down by annular slide fastener portion (20), pay wages with the saving funds.
