摘要： A positioning error prevention hoop including a hoop body curled to form a sleeving area. After a limiting member is connected on the hoop body, a limiting block of the limiting member abuts against an end of a pipe to control a distance between the hoop body and an end surface of the pipe, such that the hoop body may be secured on an appropriate position. A fastening component is clamped to tighten the hoop body on the pipe. As such, the hoop body will not tend to fall off from the pipe and may also squeeze the pipe and fit it with a connecting piece to form sealing.

摘要： This application provides a clamp and a method for using the same. The clamp includes a clamping band which is wound to form a clamp body defining an accommodating area. The clamp body is provided with a tightening lug. The clamp body includes an overlapping portion and a single layer portion which is provided with a positioning member. The positioning member is connected to the clamp body such that the positioning member is slidable toward an inner side of the accommodating area with one end extending into the accommodating area. An inner wall of the clamp body is gradually approaching an outer wall of a pipe with the tightening of the clamp, the positioning member moves outward relative to the clamp body until the inner wall of the clamp body rests against the outer wall of the pipe, and then the positioning member falls off from the clamp body.

摘要： The present invention discloses a hoop as well as a manufacturing method and a use method of the hoop. The hoop comprises a clamping belt, wherein the clamping belt is bent to form a hoop body with a sleeving area; the hoop body forms a superposed part; the superposed part comprises an outer belt body and an inner belt body: and the sleeving area is elliptical. The manufacturing method thereof comprises the steps of producing a clamping belt at first, and then directly bending the clamping belt to form a hoop body with an elliptical sleeving area. The use method thereof comprises the steps of directly bending a clamping belt to form a hoop body with a sleeving area, carrying out pre-forming treatment on the sleeving area to enable the sleeving area to be elliptical, sleeving the hoop body on a pipe fitting to enable the hoop body to form abutting connection with the pipe fitting at a short shaft part corresponding to the sleeving area, and further shrinking and clamping the hoop through a hoop clamping tool. The present invention aims at providing a hoop. The hoop has the advantages of being convenient in installation and capable of being effectively pre-fixed to the pipe fitting.
