Description
A kind of rapid pipe joint relates to flexible pipe with the joint that connects between hard tube.
At present, hard tube is with the most occasions of the connection between flexible pipe, be with the flexible pipe cuff on hard tube.Very inconvenience when this connecting mode uses.The Chinese patent application pipe discloses a kind of " automatic washing machine fill hose joint " for No. 90211220.1, and part has overcome above-mentioned deficiency.It is made up of acorn nut, locking ring, pipe joint seat, sealing gasket, pipe joint.Utilize acorn nut to suppress to place the locking ring of the taper hole of pipe joint seat, the turn nut can make locking ring draw and clamp water tap under the effect of taper hole.Yet the purpose of this joint in order to realize being connected firmly with water tap needs special locking ring; And the effect in order to realize sealing needs processing one cylindrical boss in the pipe joint, and sealing gasket is placed on the boss.Therefore its Component still show more, and structure is more complicated also, use also inconvenient.
The purpose of this utility model provides a kind of improved rapid pipe joint, and it can link to each other flexible pipe easily with hard tube.
Adopt such technological scheme according to above-mentioned purpose the utility model: this joint comprises the lower nut that connection block, acorn nut and endoporus have tapering, acorn nut is with connection block upper end bolt, middle part, connection block lower end is a center tube, be fixed with flexible blade around center tube, described lower nut is with connection block lower end bolt, it is characterized in that acorn nut is with leaving the space between the connection block outer wall, rubber ring is positioned at connection block and crosses the connection block top and extends to acorn nut with the space between the connection block outer wall, and the connection block inwall is with leaving the gap between rubber ring.
The utility model is because employing extends to acorn nut with between the connection block outer wall with rubber ring, and rubber ring is with the structure that leaves the gap between the connection block inwall.Therefore component are few, simple in structure, and only with hand touches during use, hard tube can be inserted in the rubber ring very easy to use and good sealing effect.
Below in conjunction with drawings and Examples the utility model is further described.
The quick coupling structure schematic representation that accompanying drawing the utility model proposes for foundation.
As shown in drawings, be processed with outside thread in connection block (3) upper end, acorn nut (1) inwall is processed with internal thread, and the connection block upper end is with the acorn nut bolt.Acorn nut is with leaving the space between the connection block outer wall.Rubber ring (2) is positioned at connection block, and crosses the connection block top and extend to acorn nut with in the space between the connection block outer wall.Simultaneously, the connection block inwall is with leaving gap (4) between rubber ring.When acorn nut screws in the connection block upper end, rubber ring is pressed on the connection block top.
Middle part, connection block lower end is center tube (5), is fixed with flexible blade (9) around center tube.The endoporus of lower nut (6) has tapering, and lower nut is with connection block lower end bolt.During use flexible pipe (7) is enclosed within on the center tube, screws on lower nut then.Along with the screw-in of lower nut, its tapering is partly oppressed flexible blade.Make the flexible blade lock ring on flexible pipe, thereby play the fixedly effect of flexible pipe.In order to increase the lock ring effect, be processed with teeth (8) to the one side of center tube at soft blade face.When screwing lower nut, teeth tightly are gripped on the flexible pipe.The coming off of joint in order to prevent to use preferably loaded onto chain on acorn nut.And described chain is contained on the earrings (10) that is fixed in acorn nut.During use chain is hung on the faucet handle, therefore can not come off all the time in the fixing rapid pipe joint down of the pulling force of chain.
Claims (3)
1. rapid pipe joint, comprise the lower nut that connection block, acorn nut and endoporus have tapering, acorn nut is with connection block upper end bolt, middle part, connection block lower end is a center tube, be fixed with flexible blade around center tube, described lower nut is with connection block lower end bolt, it is characterized in that acorn nut is with leaving the space between the connection block outer wall, rubber ring is positioned at connection block and gets over edge joint headstock top and extends to acorn nut with the space between the connection block outer wall, and the connection block inwall is with leaving the gap between rubber ring.
