Abstract

The invention discloses an embedded fixed-type expansion bolt which comprises a screw body, a plurality of opened slots, a plurality of pin shafts, a plurality of fixation bodies and a threaded fixation mechanism, wherein the opened slots with uniform distribution are formed in the front end of the screw body; upper ends of the opened slots pass through circumferences of the screw body; the corresponding rotatable fixation body is disposed in each of the opened slots by one of the pin shafts; the lower end of the fixation body is higher than the front end of the opened slot; the higher end ofthe fixation body is provided with a cutting part; a blocking body is disposed on the lower end of each opened slot; the threaded fixation mechanism is disposed on the screw body; the threaded fixation mechanism comprises a T-shaped nut, a tapping part and a thread part; and the tapping part and the thread part are successively disposed from front to back on circumferences of a small-diameter section of the T-shaped nut. In comparison with the prior art, the expansion bolt has the beneficial effects that fixation reliability is high; and the structure is simple.

Description

【Technical field】 [0001] The invention relates to the technical field of expansion bolts, in particular to the technical field of embedded fixed expansion bolts. 【Background technique】 [0002] Expansion bolts use the inclination of the shape to promote the expansion to generate friction and grip force to achieve the fixing effect. One end of the screw body is a screw thread, and the other end has a vertebral degree. There is a steel sheet on the outside, and there are several cuts in the half of the iron sheet cylinder. Put them together into the hole punched in the wall, and then lock the nut. The nut pulls the nut outward, and pulls the vertebra into the steel sheet cylinder. The cylinder is expanded, so it is tightly fixed on the wall, and it is generally used for fastening protective fences, awnings, air conditioners, etc. on cement, bricks and other materials. It is only fixed by the friction between the expanded steel cylinder and the wall, and there is only one fix...
