Rapid pipe joint

Technical field

The utility model relates to a kind of connection pipe fitting, is specifically related to a kind of rapid pipe joint.

Background technique

Rapid pipe joint is the device that is widely used in connecting between pipeline, existing joint is in the time connecting, fixedly using by locking bar between pipe fitting will be fixed between pipe fitting, and then locking bar is fixed with latch, such means of fixation is stable not, and the own insufficient strength of latch simultaneously, if latch fracture in connection procedure, can make locking bar loosening, thereby cause the connection between pipe fitting to disconnect.

Model utility content

For the deficiencies in the prior art, the utility model provides a kind of rapid pipe joint, and this joint adopts L-type locking bar, connects rapidly, by latch and the dual fixation of fixed hole, more firm between can pipe fitting connecting.

For achieving the above object, the utility model provides following technological scheme: a kind of rapid pipe joint, comprise rapid pipe joint main body, described rapid pipe joint main body comprises male, female and locking mechanism, described locking mechanism is symmetricly set in rapid pipe joint main body, described locking mechanism comprises fastening ear, hinge pin and L-type locking bar, described L-type locking bar comprises latch part and active part, described active part is flexibly connected with fastening ear by hinge pin, described hinge pin is less than the length of active part to the distance between female, on described fastening ear, be provided with hinge last, one end of the corresponding rapid pipe joint main body of described active part is provided with the top splenium of outwardly convex, the curved convex surface setting of face of described top splenium outwardly convex, the other end of the corresponding interactive portion of described latch part is provided with fixed hole, described L-type locking bar is provided with draw ring hole, described draw ring is provided with draw ring on hole, described female is sealing setting.

By adopting such scheme, adopt novel L-type locking bar, when connection, can the fixed hole on L-type connecting rod be fixed by lockset, coordinate again the fixing of latch, can make the connection between pipe fitting more firm, avoid when latch is because of stressed excessive fracture, cause the fixing loosening of locking bar, the connection of pipe fitting is disconnected, the draw ring hole arranging can be in unloading process, for convenience detach when fixing too tight of L-type locking bar, female is arranged to shutoff and can make the shutoff process operation of rapid pipe joint for some pipelines.

Of the present utility modelly further be set to, described female inner side is provided with rubber washer.

By adopting such scheme, rubber washer is set in the inner side of female can be in the time that pipe fitting connects, and can contact with the joint of pipe fitting to be connected closelyr, has promoted the sealing of pipe fitting.

Of the present utility modelly further be set to, described rapid pipe joint is provided with two stiffening ribs, and described stiffening rib is symmetricly set in rapid pipe joint main body.

By adopting such scheme, two stiffening ribs are symmetricly set in rapid pipe joint main body and can share more uniformly the active force that rapid pipe joint is subject to, increase the serviceability of rapid pipe joint.

Embodiment

Referring to figs. 1 through Fig. 3, the utility model rapid pipe joint embodiment is described further.

A kind of rapid pipe joint, comprise rapid pipe joint main body, described rapid pipe joint main body comprises male 1, female 2 and locking mechanism 3, described locking mechanism 3 is symmetricly set in rapid pipe joint main body, described locking mechanism 3 comprises fastening ear 4, hinge pin 5 and L-type locking bar 6, described L-type locking bar 6 comprises latch part 14 and active part 15, described active part 15 is flexibly connected with fastening ear 4 by hinge pin 5, described hinge pin 5 is less than the length of active part 15 to the distance between female 2, on described fastening ear 4, be provided with hinge last 10, one end of the corresponding rapid pipe joint main body of described active part 15 is provided with the top splenium 8 of outwardly convex, the curved convex surface setting of face of described top splenium 8 outwardly convexs, the other end of the corresponding active part 15 of described latch part 14 is provided with fixed hole 9, described L-type locking bar 6 is provided with draw ring hole 7, on described draw ring hole 7, be provided with draw ring 11, described female 2 is sealing setting, in rapid pipe joint main body, be provided with two stiffening ribs 13, described stiffening rib 13 is symmetricly set in rapid pipe joint main body, female 2 inner sides are provided with rubber washer 12.

Adopt novel L-type locking bar 6, when connection, can the fixed hole in latch part 14 9 be fixed by lockset 16, coordinate again the fixing of latch (not marking in figure), can make the connection between pipe fitting more firm, when connection, first the male of the joint of quick water pipe 1 is enclosed within on the joint of pipe fitting to be connected, the joint of pipe fitting to be connected is withstood on the rubber washer 12 of quick water pipe joint inner side, then L-type locking bar 6 is up pulled, the joint of pipe fitting to be connected is blocked with the top splenium 8 of L-type locking bar 6, then by overlapping the fixed hole of two L-type locking bars 69, finally by lockset 16, fixed hole 9 is pinned, again latch is inserted in hinge last 10, can complete fixing, when dismounting, first latch is pulled up, then lockset 16 is opened, L-type locking bar 6 is down pulled, the draw ring hole 7 that is arranged on corresponding fixed hole 9 sides can (it should be noted that in unloading process herein, described draw ring hole 7 can be arranged on the arbitrary position of L-type locking bar 6, be arranged on a side of the corresponding fixed hole 9 of L-type, can be convenient pull L-type locking bar 6, so locate to implement preferably) in the time of fixing too tight of L-type locking bar 6, by the draw ring 11 L-type locking bar 6 of leaving behind, for convenience detach, after having connected, by lockset 16 and latch simultaneously for fixed L type locking bar 6, can avoid when latch is because of stressed excessive fracture, cause the fixing loosening of locking bar, the situation that the connection of pipe fitting is disconnected, female 2 is arranged to shutoff and can make the shutoff process operation of rapid pipe joint for some pipelines, at least two stiffening ribs 13 are set can increase the intensity of joint self, promote the serviceability of rapid pipe joint.

Rubber washer 12 is set in the inner side of female 2 can be in the time that pipe fitting connects, and can contact with the joint of pipe fitting to be connected closelyr, has promoted the sealing of pipe fitting.
