Description

The scissors EXPANSION ANCHOR BOLTS

Technical field

The utility model relates to a kind of scissors EXPANSION ANCHOR BOLTS in the fastener areas.

Background technique

Since the EXPANSION ANCHOR BOLTS of Britain engineer John Joseph Rawlins invention in 1911; People use its whole century, and along with the promotion and application of porous wall building block, the EXPANSION ANCHOR BOLTS of the above-mentioned type is because folding degree and rigidity are limited; The capable rightly anchoring of hole wall in very difficult realization and the porous building-brick body of wall or safe sealed; Normally turning from side to side repeatedly, is the passable use of having no way out at last, and the result has buried many potential safety hazards.From the thing of existing patent documentation record, do not find better solution yet.

Summary of the invention

The purpose of the utility model is exactly to design a kind of new scissors EXPANSION ANCHOR BOLTS to above-mentioned present situation; It is in one Chinese patent application number to be: continue innovation and perfect on 201110218903.3 the scissors EXPANSION ANCHOR BOLTS basis, its scheme is abundant more, reliable and practical.

The technical solution of the utility model:

1. designed the expansion oplate that a kind of two ends are the inclined-plane (1); Expansion oplate (1) is provided with pilot hole (2) and (3); Two expansion oplates (1) merge the nut bearing (4) that is inlaid in the band ear and go up and connect through riveting axle (5); Band cap screw rod (6) spinning is on the nut bearing (4) of band ear, and two inclined-planes that promote expansion oplate (1) through band cap screw rod (6) make it strut as scissors, and then realizes the purpose of anchoring or locking;

2. be the inclined-plane with the junction plane (7) between two basal part of the ear portions on the nut bearing (4) of ear, inwardly rotate through this inclined-plane confined expansion plate (1);

3. the inclined-plane of an end end of expansion oplate (1) leans against on the inclined-plane of junction plane (7), and return spring (8) is housed on the pilot hole of the other end (2), draws the expansion oplate (1) that is strutted in through return spring (8), and then realizes that EXPANSION ANCHOR BOLTS is detachable;

4. the EXPANSION ANCHOR BOLTS that is made up of two expansion oplates (1) is the basic structure of the utility model; Realize the combination serial connection of polylith expansion oplate (1) through pilot hole on the expansion oplate (1) (2,3) and riveting axle (5,9,10); And then reaching the purpose that strengthens anchoring or locking, this kind even scissors expansion of structure bolt is fit to anchoring or locking on macropore brick cavity wall and the closely knit soil more;

5. the precession end with cap screw rod (6) can be the plane; It also can be sphere; The cap of the other end can be a hexagon head; Also can be: hexagonal headband screw rod, hexagon head flanged surface, hexagon socket head, hexagon socket head band outside thread, outer-hexagonal headband internal thread, hook, suspension ring, cross recess, and then realize multiduty needs;

6. the spindle nose of riveting axle (5) can sink in the nut bearing (4) of band ear, also can stretch out outside (4);

7. the two end part of expansion oplate (1) can be symmetry equivalent apart from the distance of pilot hole (3), also can be unequal, can realize fast that through unequal significantly scissors strut.

The beneficial effect of the utility model:

The utility model has been started the EXPANSION ANCHOR BOLTS novel type, has satisfied the new demand of people's application and application target and using effect, on porous building-brick body of wall and closely knit soil, can use especially solid and reliablely, has really realized the general value of EXPANSION ANCHOR BOLTS.

Embodiment

Below in conjunction with accompanying drawing the utility model and practical implementation are described further:

Referring to accompanying drawing; 1. designed the expansion oplate that a kind of two ends are the inclined-plane (1); Expansion oplate (1) is provided with pilot hole (2) and (3), and two expansion oplates (1) merge the nut bearing (4) that is inlaid in the band ear to be gone up and connect through riveting axle (5), and band cap screw rod (6) spinning is on the nut bearing (4) of band ear; Two inclined-planes that promote expansion oplate (1) through band cap screw rod (6) make it strut as scissors, and then realize the purpose of anchoring or locking; 2. be the inclined-plane with the junction plane (7) between two basal part of the ear portions on the nut bearing (4) of ear, inwardly rotate through this inclined-plane confined expansion plate (1); 3. the inclined-plane of an end end of expansion oplate (1) leans against on the inclined-plane of junction plane (7), and return spring (8) is housed on the pilot hole of the other end (2), draws the expansion oplate (1) that is strutted in through return spring (8), and then realizes that EXPANSION ANCHOR BOLTS is detachable; 4. the EXPANSION ANCHOR BOLTS that is made up of two expansion oplates (1) is the basic structure of the utility model; Realize the combination serial connection of polylith expansion oplate (1) through pilot hole on the expansion oplate (1) (2,3) and riveting axle (5,9,10); And then reaching the purpose that strengthens anchoring or locking, this kind even scissors expansion of structure bolt is fit to anchoring or locking on macropore brick cavity wall and the closely knit soil more; 5. the precession end with cap screw rod (6) can be the plane; It also can be sphere; The cap of the other end can be a hexagon head; Also can be: hexagonal headband screw rod, hexagon head flanged surface, hexagon socket head, hexagon socket head band outside thread, outer-hexagonal headband internal thread, hook, suspension ring, cross recess, and then realize multiduty needs; 6. the two end part of expansion oplate (1) can be symmetry equivalent apart from the distance of pilot hole (3), also can be unequal, can realize fast that through unequal significantly scissors strut.

The spindle nose of above-mentioned riveting axle (5) can sink in the nut bearing (4) of band ear, also can stretch out outside (4), and the purpose of stretching out is an antislip; If it is bigger than normal that mounting hole is beaten; Can earlier littlely revolve band cap screw rod (6) expansion oplate (1) is opened a little, and then put it in the mounting hole, but so also antislip.

The utility model can relieved anchoring reliably or locking on brick cavity wall, solid brick wall, cob wall, concrete, plastics, wooden structures, closely knit soil materials such as (functions with stake) or structure, has really realized the general value of EXPANSION ANCHOR BOLTS.

Implementing the material that the utility model is selected for use, advise first-selected plain carbon steel, secondly is stainless steel; Specific (special) requirements can be selected middle-carbon steel for use and heat-treated; Along with the development and the application of plastics and composite material thereof, the utility model also can have breakthrough in this respect, as for the sized of the utility model; Aspects such as surface treatment should be decided according to market demand, and more how conspicuous thing is not just given unnecessary details here.
