Abstract
The utility model provides an internally-expanded expansion bolt used for installation. Not only can the expansion bolt expand inwards, but also an expanding screw can be screwed more and more tightly, and consequently expansion degree of an object can be greatly increased. The internally-expanded expansion bolt used for installation comprises an internally-expanded bolt and a screw. One end of the internally-expanded bolt is in an open type, and the other end of the internally-expanded bolt is provided with a gap in a semi-sealing type. A tip end of the screw is inserted into the inside of the internally-expanded bolt through the open end of the internally-expanded bolt and matched with the internally-expanded bolt in threaded mode. Two sides of threads at the tail of the internally-expanded bolt are in a split type. A nut matched with the screw is designed to be in a flange head shape. Therefore, the internally-expanded expansion bolt used for installation can save cost of gaskets and improves installation efficiency. A waterproof rubber cushion is disposed at the screw and the nut, so a thermal insulating layer can be effectively protected. The internally-expanded expansion bolt used for installation is waterproof and can be expanded tightly.
Description
Affiliated technical field
The utility model relates to a kind of internal-expansion type EXPANSION ANCHOR BOLTS that is used to install, and the internal-expansion type EXPANSION ANCHOR BOLTS of the utility model can inwardly expand when mounted, and outside power is become inside power.
Background technique
At present, known EXPANSION ANCHOR BOLTS is made up of nut, the bolt that expands, the structure that common EXPANSION ANCHOR BOLTS expands outside being mostly to adopt when screwing nut, and such structure is not enough to the swelling degree of object.The body of wall that has thermal insulation layer during simultaneously for installation has very holocaust.
Summary of the invention
In order to overcome the deficiency of existing EXPANSION ANCHOR BOLTS, the utility model provides a kind of internal-expansion type EXPANSION ANCHOR BOLTS that is used to install, and this EXPANSION ANCHOR BOLTS can not only inwardly expand, and bloated nail revolves tighter and tighter, can improve the swelling degree of object greatly.The utility model solves the technological scheme that its technical problem adopted: a kind of internal-expansion type EXPANSION ANCHOR BOLTS that is used to install; Bolt and screw expand in comprising; An end opening of bloated bolt in described, the other end is semiclosed, and the slit is arranged; The bolt that expands in the tip of described screw stretches to from the opening end of interior bloated bolt is inner, and with bloated bolt screw-thread fit.
The bolt tail side that expands in described has convexity, splits in described interior both sides of expanding the bloated bolt screw thread of bolt tail side, and the nut of described screw is the flange head design; Can save the pad cost, improve installation efficiency, there is waterproof pad at described screw-nut place; Effectively protection thermal insulation layer, waterproof and swelling.
The beneficial effect of the utility model is: can strengthen swelling degree to body of wall, and not quick detachable.Be applicable to the body of wall that has thermal insulation layer, waterproof thermal-insulated.With the outer structure that expands of common EXPANSION ANCHOR BOLTS, become inside expansion, strengthen the degree of screwing to body of wall.

Embodiment
Referring to Fig. 1 and Fig. 2, the utility model relates to a kind of internal-expansion type EXPANSION ANCHOR BOLTS that is used to install, the bolt 1 that expands in comprising, and screw 2 is formed with waterproof pad 3.An end opening of bloated bolt 1 in described, the other end is semiclosed, and the slit is arranged, and the tip 4 of described screw 2 stretches to interior bolt 1 inside of expanding from the opening end of interior bloated bolt 1, and cooperates with bloated bolt screw thread 5.
The bolt 1 tail side that expands in described has convexity, splits in described interior bloated bolt screw thread 5 both sides of expanding bolt 1.The nut 6 of described screw 2 is flange head designs, can save the pad cost, improves installation efficiency.There is circular waterproof pad 3 at described nut 6 places, effectively protect thermal insulation layer.
The utility model is when in use: interior bloated bolt is penetrated in the mounting hole, and outside rotary screw then is because screw and bloated bolt are screw-thread fit; After bloated bolt is fixed; The interior bloated bolt of this EXPANSION ANCHOR BOLTS inwardly expands rapidly to the screw effect, thereby clamps marble or ceramic tile, improves the swelling degree of object greatly; Save installation cost and installation time, improved installation efficiency.
Claims (4)
