Technical scheme provided by the present invention is: a kind of plastic wall bolt, it comprises tightening latch, bolt cap, hold down gag, the two ends of tightening latch are provided with screw thread, be bolted with the bolt cap on the screw thread of one end, the bolt cap is provided with locating hole, alignment pin is housed on the locating hole, the port of bolt cap is provided with boss, boss is provided with positioning convex, and the other end of tightening latch is equipped with hold down gag, and hold down gag comprises clamping pad, compresses mother, clamping pad with compress female contact jaw and be provided with cavity, be provided with jump ring in cavity, compress a female end and be provided with boss, the jump ring kayser is on boss.The use length that alignment pin on the bolt cap is regulated tightening latch by locating hole, during use, the positioning convex plug-in card of bolt cap is in the middle of template back arris.
Further, the tightening latch cross section is circular.
Further, the tightening latch inner core is a metal material, and the table body is coated by engineering plastics.
Further, the metal material of tightening latch inner core is a round steel.
Further, the inner core of tightening latch is welded with spacer, and spacer is an annular, and interior ring diameter is identical with the tightening latch inner core diameter, and in be equipped with through hole; Be equipped with the triangular shape projection outward, inner core is fixed in the table body.
Further, spacer is welded in the middle unthreaded portion of tightening latch.
Further, be welded with on the inner core at tightening latch two ends and compress sheet, compressing sheet is annular, and interior ring diameter is identical with the tightening latch inner core diameter, and in be equipped with through hole; Be equipped with projection outward, describedly compress the screw thread place that sheet is welded in the tightening latch two ends.
Further, bolt cap and hold down gag are made by engineering plastics.
The present invention has following advantage: wall piercing bolt simple in structure, light practicality, the tensile strength height is saved great deal of steel, and easy to operate, with low cost, very easily by taking out in the concrete after solidifying, and because the table body adopts engineering plastics, product of the present invention can not corrode, and the ash on wall piercing bolt surface stain is convenient to cleaning, can repeatedly reuse.
