Problems solved by technology

[0003] Because, this kind of buckle 9 must use other auxiliary tools (such as wrench) to lock this tightening member 94 on this screw rod 93 in addition in the locking process, so it can be understood that this kind of buckle 9 cannot Directly let the installer complete the locking work by hand, so there is a disadvantage of inconvenient use
In addition, in the process of using auxiliary tools to tighten the tightening member 94, not only the screw rod 93 is prone to chipping, but the tightening member 94 is also prone to breakage and the hand of the installer is easily injured. Buckle 9 is actually less secure doubts
[0004] Furthermore, the screw 93 is also easy to disengage from the second positioning end 921 due to an external force, so that the first and second half fasteners 91, 92 cannot be tightly clamped on the joint 81 of the pipe 8 , and then lose the effect of preventing fluid from leaking outward from the junction 81 of the pipe fitting 8

Abstract

A retaining ring comprises a first half retaining part, a second half retaining part and a packing unit. The first half retaining part and the second half retaining part are pivoted. The first half retaining part comprises a first positioning end. The second half retaining part comprises a second positioning end capable of being opened and closed relative to the first positioning end. The packing unit comprises a rack arranged at one of the first positioning end and the second positioning end, a tooth part which is located in another of the first positioning end and the second positioning end and can be engaged with the rack, and a control element set used for limiting unidirectional rotation of the tooth part. The design that the rack is arranged at one of the first positioning end and the second positioning end and can be engaged with the tooth part located in another of the first positioning end and the second positioning end is adopted, and thus a mounting operator can complete mounting operation easily without other auxiliary tools.

Description

technical field [0001] The invention relates to a fastener suitable for being installed at the junction of two pipe fittings, in particular to a fastener which can be installed without using other auxiliary tools during the installation process, is safe, and can effectively prevent fluid from flowing The retaining ring for leaking out of the joint of the pipe fitting. Background technique [0002] refer to figure 1 , an existing clasp 9 is suitable for being installed at the junction 81 of two pipe fittings 8 . The clasp 9 includes a first half fastener 91 and a second half fastener 92 that are pivotally connected to each other and can be used to clamp the joint 81 of the pipe 8, a screw rod 93, and a rotatable The tightening member 94 is locked on the screw rod 93 . One end of the screw 93 is pivotally mounted on a first positioning end 911 of the first half fastener 91 , and the other end of the screw 93 is a first positioning end 911 capable of passing through the seco...
