Description
Technical field
The bolt that the utility model is related to be suitable on hollow partition board, it is particularly a kind of for swollen on hollow partition board
Swollen bolt.
Background technology
One, the screw of expansion bolt is screw thread, and one has vertebra degree, outer one sheetmetal of bread, and expansion cylinder has put on several cut
Mouthful, they are put together into the hole accomplished fluently on wall, then split nut, nut pulls outward screw, and vertebra degree is pulled in sheetmetal circle
Cylinder, expands by spreading, is then just fixed on wall.
But when needing to use expansion bolt for hollow partition board, the single side wall thickness of hollow partition board only has a 15mm left sides
The right side, although can also be fixed using common expansion bolt, can because the expansion degree of expansion jacket casing it is low with wall close to
It spends bad so that expansion bolt can not hang weight, easily be skidded off from mounting hole.
Utility model content
The purpose of the utility model is to provide a kind of expansion bolts on hollow partition board.After it has expansion
Structure expansion degree height and wall approach degree it is good, weight can be hung, it is not easy to the advantages of being skidded off from mounting hole.
The technical solution of the utility model：A kind of expansion bolt on hollow partition board, including fuse, fuse one end
Equipped with external screw thread, the other end is the conehead with taper, further includes the housing that can be inserted in fuse, housing includes round set, round
Set connection taper sheath head end, taper sheath is equipped with the multiple tracks groove of the notch, when taper sheath tail end is sleeved on conehead, taper sheath and circle
The included angle A that set is formed is 120-150 °, further includes the nut that can be inserted in the upper rubber pad of round set and can be inserted in fuse.
It is previously described in the expansion bolt on hollow partition board, further includes the gasket that can be inserted in fuse.
The beneficial effects of the utility model：Compared with prior art, when the utility model is used, it only needs first in hollow batardeau
Board wall drills out mounting hole on face, and fuse band conehead end is put into mounting hole, the housing for being cased with rubber pad then is sleeved on core
On son, taper sheath tail end is sleeved on conehead, covers Upper gasket and nut on fuse later, at this moment rotating nuts, conehead meeting later
Taper sheath is squeezed, taper sheath can be carried out after being squeezed along the groove of the notch, so as to carry out expansion locking, continue rotating nut, expansion
Multi-disc taper sheath last returning can be unfolded outward on wall, this expansion structure expansion degree is high, and locking effect is good, bolt
It is not easy to skid off from mounting hole, and has rubber pad to be sleeved between bolt and mounting hole wall so that between bolt and wall
Approach degree it is good, the fixed bolt completed can hang the weight of 100kg, and load-carrying effect is very good.
In summary：The utility model has the approach degree of structure expansion degree height and wall after expansion good, can hang
Weight, it is not easy to the advantages of being skidded off from mounting hole.
Description of the drawings
Attached drawing 1 is the structure diagram of the utility model；
Attached drawing 2 is the structure diagram of fuse and conehead；
Attached drawing 3 is the structure diagram of housing.
Label in attached drawing for：1- fuses, 2- external screw threads, 3- coneheads, 4- housings, 5- circle sets, 6- taper sheaths, 7- notch

Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
Embodiment.A kind of expansion bolt on hollow partition board is formed as shown in Figs. 1-3, including fuse 1, fuse 1
One end is equipped with external screw thread 2, and the other end is the conehead 3 with taper, further includes the housing 4 that can be inserted in fuse 1, and housing 4 includes circle
Shape set 5,5 connection 6 head end of taper sheath of circle set, taper sheath 6 is equipped with the multiple tracks groove of the notch 7, when 6 tail end of taper sheath is sleeved on conehead 3
When upper, the included angle As that taper sheath 6 is formed with round set 5 are 120-150 °, further include the rubber pad 8 that can be inserted on round set 5 and
The nut 9 that can be inserted in fuse 1.
Further include the gasket 10 that can be inserted in fuse 1.
The application method and principle of the utility model：In use, mounting hole first is drilled out on hollow partition board metope, by core
13 end of band conehead of son is put into mounting hole, then the housing 4 for being cased with rubber pad 8 is sleeved on fuse 1,6 tail end set of taper sheath
On conehead 3, Upper gasket 10 and nut 9 are covered on fuse 1 later, at this moment rotating nuts 9, nut 9 resist gasket 10 to taper
Cover 6 close, then gasket 10 can resist round set 5, continue rotating nuts 9, and conehead 3 can squeeze taper sheath 6, taper sheath 6 by
It can carry out after extruding along the groove of the notch 7, so as to carry out expansion locking, when the included angle A that taper sheath 6 is formed with round set 5 is 120-
At 150 °, continue rotating nut 9, the multi-disc taper sheath 6 of expansion can be unfolded last returning on wall, be locked outward
Into the bolt by the fixed completion of test can hang the weight of 100KG.
