Description
Technical field
The utility model relates to the house decoration class, is a kind of detachable rotary back of the body bolt concretely.
Background technique
Existing back of the body bolt external form kind is a lot, can be divided into by the basic principle of its expansion: (1) drawing and pulling type; (2) hit expanding; (3) press the core formula.Drawing and pulling type wherein mainly by continuous swivel nut, stretches screw rod, thereby makes stressed the opening in crab-bolt steel bushing bottom, plays the effect that expands in a rear portion; The expanding that hits wherein is by knocking crab-bolt steel bushing formula screw rod, and reaches the effect that expands in the bottom, and all in all, traditional back of the body bolt has following shortcoming: (1) causes the cracked of stone material easily if with the knocking type back of the body bolt materials such as stone material are installed; (2) traditional back of the body bolt is non-removable product, if material is removed, in transportation process, causes the damage of material and the waste of back of the body bolt easily because of placement that can not be smooth; (3) Applicable scope of each product is little, and therefore of a great variety, the client selects trouble in use; (4) the product pattern is clumsy, waste material, manufacture cost height.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of detachable rotary back of the body bolt is provided, and expanding in the bottom of this back of the body bolt is to realize progressively that by the rotation of screw rod material can not impacted, simultaneously as long as counterrotating just can be removed bottom expansion and realization dismounting.
The utility model purpose realizes being finished by following technological scheme:
A kind of detachable rotary back of the body bolt comprises crab-bolt steel bushing, crab-bolt, it is characterized in that described crab-bolt steel bushing internal chamber wall is provided with the gradient internal thread, and described crab-bolt is a screw rod, and the crab-bolt steel bushing is threaded with crab-bolt.
One end of the crab-bolt of screw shaped has the installation slotted eye, is evenly distributed with two semienclosed slots on the crab-bolt steel bushing sidewall at least.
The utility model has the advantages that simple and reasonable for structure, cost is low, easy construction.
