Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is connection relationship diagram between the utility model buffer stopper, buffer spring and push plate.
In figure: 1 tube body, 101 expansion plates, 102 movable blocks, 103 buffer layers, 104 pencils, 105 idler wheels, 2 buffering connection dresses
It sets, 201 buffer stoppers, 202 buffer springs, 203 push plates, 204 nuts, 205 screw rods.
Specific embodiment
It is according to the present utility model in a first aspect, the utility model provides a kind of expansible chemical anchor bolts, such as Fig. 1-2 institute
Show, including tube body 1 and buffer connecting rods 2, one end of tube body 1 are fixedly installed with buffer stopper 2.
Tube body 1 includes expansion plate 101, and the inside of expansion plate 101 offers several through-holes being connected with pencil 104,
The internal activity of expansion plate 101 is equipped with movable block 102, and the inside of movable block 102 is fixedly installed with buffer layer 103, buffer layer
103 inside is fixedly installed with pencil 104, and the shape of pencil 104 is hollow double-layer glass tube, and the both ends of expansion plate 101 are logical
It crosses shaft and is movably installed with idler wheel 105.
Buffer connecting rods 2 include buffer stopper 201, are fixedly installed with buffer spring on the left side side wall of buffer stopper 201
202, one end of buffer spring 202 is fixedly installed with push plate 203, and one end of expansion plate 101 is solid with the form welded and push plate 203
Fixed connection, the shape of the one end of expansion plate 101 far from push plate 203 are hemisphere, and the hemispheroidal installation is towards expansion plate 101
Inside, the right sidewall of buffer stopper 201 are fixedly installed with nut 204, and the shape of buffer stopper 201 and push plate 203 is annular shape,
And the diameter of internal annulus is identical as the interior circular diameter of nut 204, the inside of nut 204 has been connected through a screw thread screw rod 205.
Working principle: in use, after producing the through-hole in suitable aperture by electric drill in installation site, it will be floating inside hole
Ash is repeated multiple times clear up until the anchor bolt is put into anchor hole with after bright water without floating ash in hole, by external tool to slow
It rushes block 201 to be beaten, during beaing, the impact force being subject to is transferred to buffer spring 202 by buffer stopper 201, buffering
Spring 202 absorbs a part of impact energy by the contraction of itself, in the elongation by itself and passes through the cooperation with idler wheel 105
Under, the anchor bolt is mobile to anchor hole depths, after anchor bolt reaches designated position, stops beaing at this time, screw rod 205 is passed through into nut
204, make screw rod 205 in rotation to moving inside anchor bolt using screw thread, when screw rod 205 is moved to the inside of movable block 102,
Continue the pressure breakage progressive, pencil is given in screw rod 205 with screw rod 205, internal medical fluid flows out and passes through expansion plate
Through-hole on 101 is contacted with wall, at the same with the advance of screw rod 205,102 continued advancement of movable block and with before expansion plate 101
