Abstract
The utility model belongs to the technical field of fasteners and particularly relates to an expansion bolt. The expansion bolt comprises a hollow expansion sleeve, a bolt body and a nut. The bolt body is disposed in the expansion sleeve in a matched manner. The nut is disposed at one end of the bolt body in a threaded manner. The expansion bolt is characterized in that inner threads and an outer spiral piece are respectively integrally formed on the inner wall and the outer wall at one end of the expansion sleeve. Outer threads which are matched with inner threads are arranged at one end of the bolt body. The expansion bolt is simple in process, low in production cost and convenient in construction, the plastic expansion bolt is inserted in a hole drilled in advance, fixation is achieved by tightening the bolt body to allow the expansion sleeve to expand, work efficiency is improved greatly, exposed length of the bolt body can be controlled optionally by cooperation of the inner threads and the outer threads, and overall smoothness of a wall is achieved.
Description
Technical field
The utility model belongs to technical field of fastening, is specifically related to a kind of EXPANSION ANCHOR BOLTS.
Background technique
EXPANSION ANCHOR BOLTS all has a wide range of applications in fields such as structural element connection, house decoration, equipment installations.When the exterior wall dried hanging decoration panel, need use EXPANSION ANCHOR BOLTS, to realize the decorative effect of exterior wall, usually the EXPANSION ANCHOR BOLTS of using in the exterior wall dried hanging decoration panel is furnished with expansion sleeve mostly, need punch at body of wall in use, loading back bolt exposed parts length is difficult to grasp, owing to should keep in one plane after the exterior wall cladding construction, therefore after EXPANSION ANCHOR BOLTS is fixed on the wall, must guarantee outer wall surface in one plane, this just has higher requirement to the installation precision of EXPANSION ANCHOR BOLTS, has deviation to influence construction quality easily slightly.
The model utility content
At problems of the prior art, the utility model purpose is a kind of EXPANSION ANCHOR BOLTS is being provided.
The utility model is realized by the following technical programs:
Described a kind of EXPANSION ANCHOR BOLTS, the expansion sleeve, the body of bolt and the nut that comprise hollow, the body of bolt is equipped with in expansion sleeve, nut is spirally connected and is arranged on an end of the body of bolt, it is characterized in that on the inside and outside wall of described expansion sleeve one end one-body molded internal thread and the external spiral sheet of being provided with respectively, an end of the described body of bolt is provided with the outside thread that uses with screw-internal thread fit.
Described a kind of EXPANSION ANCHOR BOLTS is characterized in that the end face of the end that the described body of bolt is connected with nut is provided with groove.
Described a kind of EXPANSION ANCHOR BOLTS is characterized in that described groove is straight groove or cross recess.
Described a kind of EXPANSION ANCHOR BOLTS is characterized in that the middle part of described expansion sleeve is symmetrically arranged with boss, described boss and the one-body molded setting of external spiral sheet.
Described a kind of EXPANSION ANCHOR BOLTS is characterized in that described expansion sleeve adopts plastic cement material to make.
The utility model preparation process is simple, cost of production is low, in boring good hole in advance, insert the plastic cement EXPANSION ANCHOR BOLTS, the utilization body that tights a bolt makes expansion sleeve expansion and reaches fixing purpose, easy construction has improved working efficiency greatly, simultaneously internal thread and externally threaded cooperation, can arbitrarily grasp the length of body of bolt exposed parts, to realize the planarization of metope integral body.
