Expansion bolt convenient to use

Abstract

The invention discloses an expansion bolt convenient to use. The expansion bolt comprises a bolt body, a lower sleeve, an upper sleeve and a bolt tail body, wherein the top of the bolt body is connected with a bolt tail joint; the bolt tail body is welded at the top of the bolt tail joint; the top of the bolt tail body is connected with a bolt tail; a nut sleeves on the front end of the bolt body; the upper sleeve and the lower sleeve are respectively mounted at the middle part of the bolt body; the middle parts of the upper and lower sleeves are fixed through spring washers; forked plates are respectively arranged at the tail parts of the upper and lower sleeves. The expansion bolt convenient to use is simple in structure and convenient to install; the expansion bolt is integrally provided with separated sleeves which are respectively the upper sleeve and the lower sleeve; therefore, on one hand, a stabilization effect can be effectively played; on the other hand, by the separated sleeves, a user can easily expand the sleeves by just simply screwing the bolt, so that the sleeves can be inserted into a wall and the bolt can be fixed more firmly.

Description

technical field [0001] The invention relates to the technical field of hardware, in particular to an easy-to-use expansion bolt. Background technique [0002] Expansion bolt is a special threaded connection used to fix pipeline supports / hangers / brackets or equipment on walls, floors, and columns. [0003] At present, the general expansion bolts on the market, because the bolt casing is an integral tube design, although the tube body is stronger, but after being sent into the through hole, the tube body is easy to break during the process of stretching, and the entire tube body breaks. As a result, it cannot be stably fixed on the wall, does not play the due role of the expansion bolt, and is not suitable for popularization and use. Contents of the invention [0004] The purpose of the present invention is to provide an easy-to-use expansion bolt, which has a simple structure, is easy to install, is very stable as a whole, does not crack, and can effectively ensure the fas...
