Abstract
The utility model discloses a kind of environment protection type and tear compound breathing bolt open, by bolt, sleeve pipe, hole depth pin and nut composition, it is characterized in that: the right part of bolt (3) has screw thread, right-hand member has flat tenon (8), left end has expansion-head (6), sleeve pipe (4) is circular casing, of sleeve pipe, hole depth pin (5) is housed, the box face becoming equilateral triangle corresponding on sleeve pipe (4) end face on hole depth pin both sides and with hole depth pin has four flat mouths (7), the other end of sleeve pipe is with flange (2), bolt (3) pierces into circular casing (4) endoporus, expansion-head (6) coordinates with the sleeve pipe left end having flat mouth (7), mounting nuts (1) on the screw thread of microcephaly's right-hand member, composition breathing bolt.The expansion-head (6) of bolt (3) is just to one side of hole depth pin (5) jagged (9), and all the other are tapers of band radian.The utility model can be dismantled, and bolt can repeatedly use, and economizes on resources, protection of the environment.
Description
Technical field
The utility model relates to EXPANSION ANCHOR BOLTS, and particularly a kind of environment protection type tears compound breathing bolt open.
Background technique
EXPANSION ANCHOR BOLTS of the prior art can not be dismantled after using, and can only once use, and waste resource, can not reach the object of saving.
Summary of the invention
The purpose of this utility model is to provide a kind of environment protection type to tear compound breathing bolt open, and this bolt can be dismantled after using, and can repeatedly use, and reaches the object of saving.
Formation of the present utility model: a kind of environment protection type tears compound breathing bolt open, by bolt, sleeve pipe, hole depth pin and nut composition, it is characterized in that: the right part of bolt has screw thread, right-hand member has flat tenon, left end has expansion-head, sleeve pipe is circular casing, of sleeve pipe, hole depth pin is housed, the box face becoming equilateral triangle corresponding in the box face on hole depth pin both sides and with hole depth pin has four flat mouths, the other end of sleeve pipe is with flange, bolt pierces into circular casing endoporus, expansion-head coordinates with the sleeve pipe left end having flat mouth, mounting nuts on the screw thread of microcephaly's right-hand member, composition breathing bolt.
The expansion-head of bolt is just jagged to one side of hole depth pin, and all the other are tapers of band radian.
Compared with the prior art, the utility model can be dismantled, and makes resource and environmental protection obtain positive effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model, and Fig. 2 is the A-A sectional view of Fig. 1, and Fig. 3 is the left view of Fig. 1, and Fig. 4 is the utility model outline drawing.
In figure 1, nut.2, flange, 3, bolt, 4, sleeve pipe, 5, hole depth pin, 6, expansion-head, 7, flat mouth, 8, flat tenon, 9, breach.
Embodiment
Shown in Fig. 1-Fig. 4, a kind of environment protection type tears compound breathing bolt open, by bolt, sleeve pipe, hole depth pin and nut composition, it is characterized in that: the right part of bolt 3 has screw thread, right-hand member has flat tenon 8, left end has expansion-head 6, sleeve pipe 4 is circular casings, of sleeve pipe, hole depth pin 5 is housed, the box face becoming equilateral triangle corresponding on sleeve pipe 4 end face on hole depth pin both sides and with hole depth pin has four flat mouths 7, the other end of sleeve pipe is with flange 2, bolt 3 pierces into circular casing 4 endoporus, expansion-head 6 coordinates with the sleeve pipe left end having flat mouth 7, mounting nuts 1 on the screw thread of microcephaly's right-hand member, composition breathing bolt.
The expansion-head 6 of bolt 3 is just to one side of hole depth pin 5 jagged 9, and all the other are tapers of band radian.
During use, after accomplishing fluently with percussion drill the hole meeting hole depth pin size on basis, bolt is inserted, fastening nut.During dismounting, nut is return 1 centimeter, with hammer by the down tip-tap or pull with spanner of flat for bolt tenon, the expansion-head of bolt can be made to get back to original position, and now prize sleeve opening with bottle opener, bolt exits by the whole series.Through test, this bolt can use repeatedly and intensity is constant, until change new sleeve pipe after casing failure, can use again.
