Abstract
The utility model relates to an integrally dismountable expansion bolt, which comprises: a nut, an elastic pad, a flat pad, a screw with a screw thread at the rear end and a conical surface at the top and an expansion sleeve. The screw is punched in the drilled bore after being combined with the expansion sleeve, the pads, the nut and the other components. A guide rib on the screw is driven by a screw down nut to shift along a guide opening of the expansion sleeve, and the guide opening at the screw thread end of the expansion sleeve expands to fasten the expansion bolt. When dismounting, the expansion bolt can be integrally taken out from the wall by using a spanner or a screw driver to clamp the spanner bayonet at the screw thread end and rotate counterclockwise, and clipping the guide opening of the expansion sleeve by the guide rib on the screw for driving the entire expansion bolt to screw out along the screw thread direction of the expansion sleeve, after unscrewing the nut and dismounting the hanger. The utility model has simple processing technology, low cost and convenient operation.
Description
Technical field
But the utility model relates to that a kind of processing technology is simple, the EXPANSION ANCHOR BOLTS of overall pulling down after the low cost of manufacture, use.
Background technique
In the present technology about EXPANSION ANCHOR BOLTS, the most original the most frequently used EXPANSION ANCHOR BOLTS mainly is the screw rod by a top band conical surface body, and an expansion sleeve and a nut are formed.The nut of EXPANSION ANCHOR BOLTS is screwed onto the appropriate location, squeezes into and bore in the good hole, fastening nut then, the top that makes screw rod expands expansion sleeve to outer displacement, and EXPANSION ANCHOR BOLTS is fixed the most at last.Can not remove after the shortcoming of this kind EXPANSION ANCHOR BOLTS maximum is to use, hanger is removed the back EXPANSION ANCHOR BOLTS and is also stayed on the wall and can't remove, and it is attractive in appearance both to have influenced metope, is injuring the pedestrian again easily.
But the purpose of this utility model is exactly, and a kind of processing technology of design is simple, the EXPANSION ANCHOR BOLTS of overall pulling down behind the low production cost, use.
Summary of the invention
The utility model comprises nut, bullet pad, plain cushion, expansion sleeve, screw rod.Screw rod (1) top band conical surface body (0) is terminal threaded, and conical surface body (0) links to each other with 1-4 guiding rib (2), and guiding rib (2) external diameter is consistent with expansion sleeve (4) external diameter.The spanner bayonet socket (3) of screw rod (1) threaded end can be a parallel surface, thrihedron, tetrahedron, hexahedron or be recessed in-line, recessed cross, recessed thrihedron, recessed tetrahedron, recessed hexahedron at the threaded end end face, is convenient to the operation of spanner or screw-driver.Expansion sleeve (4) inflating end has 1-4 guide openings (6), and at outside rolling one section screw thread (5) of guide openings (6) one ends, upward guiding rib (2) width is consistent with screw rod (1) for guide openings (6), and it is consistent with expansion sleeve (4) external diameter that expansion sleeve screw thread (5) is located external diameter.
Description of drawings
Accompanying drawing is the utility model overall structure schematic representation.(1) screw rod, (2) guiding rib, (3) screw flight end spanner bayonet socket, (4) expansion sleeve, (5) expansion sleeve screw thread, (6) expansion sleeve guide openings, (7) plain cushion, (8) bullet pad, (9) nut, (0) conical surface body.
Embodiment
The utility model is achieved in that the EXPANSION ANCHOR BOLTS after the combination is squeezed into and bores in the good hole, when screwing nut (9), the guide openings (6) of expansion sleeve (4) is subjected to displacement with screw rod conical surface body (0) under guiding rib (2) location, the guide openings (6) of expansion sleeve (4) is opened and is made helical thread portion (5) diameter expansion, and EXPANSION ANCHOR BOLTS is fixed.When needs are removed EXPANSION ANCHOR BOLTS, the nut (9) of outwarding winding, block the threaded end spanner bayonet socket (3) of screw rod (1) with spanner or screw-driver, by counter clockwise direction rotary screw (1), screw tip guiding rib (2) blocks expansion sleeve guide openings (6) and drives expansion sleeve (4) presses the rotation of screw thread (5) direction, along the wall eye to outer displacement, with EXPANSION ANCHOR BOLTS integral body from taking out within the walls.
The utility model technology simple possible, with low cost, it is convenient to remove, suitable with EXPANSION ANCHOR BOLTS fabricating cost commonly used.
Claims (4)
1. but the EXPANSION ANCHOR BOLTS of an overall pulling down is characterized in that: it is made up of a top is the terminal screwed screw rod of conical surface body, is connected in guiding rib on the conical surface body, end has guide openings expansion sleeve and plain cushion, bullet pad, nut.
