Safety Wrapped Cam Handles

Abstract

A safely-wrapped cam handle comprises a handle body, a wrapping body and a shaft hole. The handle body comprises a clamping base with a front end portion and a cam framework formed on the front end portion. The cam framework is provided with two opposite side faces, at least one embedded groove face perpendicular to the side faces and a grabbing and attaching structure defined by the embedded groove face. At least one embedding and clamping part is formed on the embedded groove face. The cam framework is wrapped with the wrapping body, and the wrapping body is made of Teflon. The wrapping body comprises an infilling part clamped and fixed by the grabbing and attaching structure and an outer wrapping part, wherein the outer wrapping part and the infilling part are integrally formed, and the outer wrapping part can be mechanically connected to the cam framework. The outer wrapping part is provided with two opposite outer side faces and a cam face connected to the side edges of the outer side faces. The shaft hole perpendicularly penetrates the outer side faces. Since the outer wrapping part is anchored to the cam framework, the safely-wrapped cam handle has the characters of Teflon, the service life is prolonged, and the application scope is enlarged.

Description

technical field [0001] The invention relates to a cam handle, in particular to a safety covering type cam handle. Background technique [0002] refer to figure 1 , an existing pipe joint includes a joint body 41 and an inner connecting pipe 42 sleeved in the joint body 41 . The connector body 41 is provided with two lugs 411 , and a cam handle 43 is arranged on each lug 411 . One end of the inner connecting pipe 42 can be inserted into the connector body 41 , and an annular groove 421 is recessed on the outer peripheral surface corresponding to the position of the ear seat 411 . The cam handle 43 has a locking seat 431 , and a cam portion 432 located at one end of the locking seat 431 , passing through a pivot pin 44 and pivotally connected to the corresponding ear seat 411 . The cam portion 432 can rotate relative to the pin 44 between a locked position and an unlocked position, so that the inner connecting pipe 42 can be quickly engaged or disengaged from the joint body...
