Abstract
The utility model relates to an anti-autorotation expansion bolt sleeve which comprises an expansion bolt sleeve; the anti-autorotation expansion bolt sleeve is characterized in that abducing fins are arranged on the expansion bolt sleeve, and are outwardly warped from the lower part of the expansion bolt sleeve to the upper part of the expansion bolt sleeve; the number of the fins on the expansion bolt sleeve is more than two. The anti-autorotation expansion bolt sleeve has the advantage as follows: the condition that the expansion bolt sleeve cannot be mounted, because the inner bolt of the expansion bolt is rotated with the expansion sleeve caused by excessively drilling, can be prevented.
Description
Technical field
The utility model relates to a kind of EXPANSION ANCHOR BOLTS cover of anti-rotation.
Background technique
In construction and installation, commonly used to EXPANSION ANCHOR BOLTS, it is made up of with cover expansion sleeve outside the inner bolt of EXPANSION ANCHOR BOLTS; It relies on the body of wall and holes, and with after the EXPANSION ANCHOR BOLTS insertion boring, turns the inner bolt of EXPANSION ANCHOR BOLTS then; After the inner bolt of EXPANSION ANCHOR BOLTS and the screw thread relative movement on the expansion sleeve, the expansion-head of the inner bolt afterbody of EXPANSION ANCHOR BOLTS is backed down expansion sleeve, and EXPANSION ANCHOR BOLTS is fixed in the boring; But in case boring is big slightly, and smoother in the hole, then when rotating the inner bolt of EXPANSION ANCHOR BOLTS; Cover expansion sleeve outside can't obtain a resistance because of the outside; Therefore can rotate with the inner bolt of EXPANSION ANCHOR BOLTS, so cover expansion sleeve outside can't launch, and also just can't EXPANSION ANCHOR BOLTS be fixed in the boring naturally; Sometimes need insert in the boring with screw-driver expansion sleeve is carried out an applied force, not allow its inner bolt to rotate with EXPANSION ANCHOR BOLTS.But improvement along with technology; Many heat conducting heat insulation expansion bolts inside and outside the partition that have are arranged now, overlap the bottom that is positioned at heat insulation expansion bolt at the expansion sleeve of back, outside holing, can't touch expansion sleeve again; Therefore in case hole excessive; Therefore then just can't carry out the installation of heat insulation expansion bolt, demand improving the expansion sleeve of EXPANSION ANCHOR BOLTS urgently, to solve the problem that expansion sleeve rotates with the inner bolt of EXPANSION ANCHOR BOLTS.
Summary of the invention
The purpose of the utility model is to solve in the existing technology in case hole excessive; The expansion sleeve of EXPANSION ANCHOR BOLTS rotates the existing problem that can't install because of the outside can't obtain a resistance with the inner bolt of EXPANSION ANCHOR BOLTS, and a kind of EXPANSION ANCHOR BOLTS cover of anti-rotation is provided.The utility model designs a kind of EXPANSION ANCHOR BOLTS cover of anti-rotation, comprises the EXPANSION ANCHOR BOLTS cover, it is characterized in that: put at EXPANSION ANCHOR BOLTS and offer the abduction fin, the abduction fin sticks up outside top from the bottom of EXPANSION ANCHOR BOLTS cover.It is characterized in that: the abduction fin that EXPANSION ANCHOR BOLTS puts has more than two.The utility model has the advantages that and to prevent to rotate and to install with the inner bolt of EXPANSION ANCHOR BOLTS because of the excessive expansion sleeve that causes of holing.
Description of drawings
Fig. 1 is the prior art constructions schematic representation, and 3 is inner bolt among the figure, and 4 is expansion sleeve.
Fig. 2 is the structural representation of the utility model.
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
Embodiment
Comprise EXPANSION ANCHOR BOLTS cover 1 among the figure, it is characterized in that: put at EXPANSION ANCHOR BOLTS and offer abduction fin 2, the abduction fin sticks up outside top from the bottom of EXPANSION ANCHOR BOLTS cover.It is characterized in that: the abduction fin that EXPANSION ANCHOR BOLTS puts has more than two.
During manufacturing, can directly put and carry out punching press, form the outer abduction fin that sticks up at EXPANSION ANCHOR BOLTS; Because the abduction fin is outer from the bottom up sticking up, and is when therefore placing EXPANSION ANCHOR BOLTS, very smooth and easy; In case after the EXPANSION ANCHOR BOLTS cover inserted boring with EXPANSION ANCHOR BOLTS, its outer abduction fin that sticks up will bump with the wall of boring, when turning the inner bolt of EXPANSION ANCHOR BOLTS; The EXPANSION ANCHOR BOLTS cover can not rotate with the inner bolt of EXPANSION ANCHOR BOLTS, after EXPANSION ANCHOR BOLTS turns, backs down the rear portion of EXPANSION ANCHOR BOLTS cover; Will EXPANSION ANCHOR BOLTS be fixed in the boring, accomplish and install.
Claims (2)
1. the EXPANSION ANCHOR BOLTS cover of an anti-rotation comprises the EXPANSION ANCHOR BOLTS cover, it is characterized in that: put at EXPANSION ANCHOR BOLTS and offer the abduction fin, the abduction fin sticks up outside top from the bottom of EXPANSION ANCHOR BOLTS cover.
2. by the EXPANSION ANCHOR BOLTS cover of the described a kind of anti-rotation of claim 1, it is characterized in that: the abduction fin that EXPANSION ANCHOR BOLTS puts has more than two.
