Abstract

The invention relates to a shearing type expansion bolt in the field of fasteners. The shearing type expansion bolt is characterized in that (a) an exposed threaded rod adopts the following working principle: two expansion plates (1) are designed, the two ends of each expansion plate are inclined surfaces, the two expansion plates (1) lean against the two sides of a lug of a lug bolt (5) and are connected by a riveting bolt (2), a wedge block (1) is sleeved on the lug bolt (5) and is supplied with power by a screw nut (7) so as to push the two inclined surfaces of each expansion plate (1) to be supported in a shearing manner and further realize the anchoring or locking; and (b) a hidden threaded mode has the same working principle as the working principle of (a). The shearing type expansion bolt is innovated and improved based on a shearing type expansion bolt with a Chinese patent application number of 201110218903.3, especially emphasizes the simplification and integrates the exposed parts and the hidden parts as far as possible, and lays a solid foundation for low-cost batch production.

Description

The scissors EXPANSION ANCHOR BOLTS

Technical field

The present invention 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 object of the invention 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 advantages of simple more; Component are shaped easily, and the shape of the component of unified as much as possible two kinds of patterns of light and shade, and then lay a good foundation for low-cost batch production.

Technical solution of the present invention:

A. bright screw rod pattern:

Designed the expansion oplate that a kind of two ends are the inclined-plane (1); Two expansion oplates (1) lean against lug bolt (5) ear both sides and connect through riveting axle (2); Voussoir (6) is enclosed within that lug bolt (5) is gone up and two inclined-planes giving power and promote two expansion oplates (1) through nut (7) make it strut as scissors, and then realization anchoring or locking.

B. dark screw rod pattern:

Two expansion oplates (1) are inlaid between two ears of lug nut (3) and through riveting axle (2) and connect; Bolt (4) spinning is on lug nut (3); One end of bolt (4) is plane or sphere; The other end is hexagon head (8) or square toes (9), and two inclined-planes that promote two expansion oplates (1) through bolt (4) make it strut as scissors, and then realizes anchoring or locking.

When lug bolt (5) was made the ears shape, two expansion oplates (1) were inlaid between two ears.

The root of the ear of lug bolt (5) and lug nut (3) is equipped with limited step, and expansion oplate (1) its inclined-plane when not strutting is leaned against on the limited step, inwardly rotates through limited step confined expansion plate (1).

Expansion oplate (1) can be a monolithic, also can be polylith, and the best is two.

The decorative pattern or the tooth that increase frictional force can be set on the anchoring face of expansion oplate (1).

Square toes (9) can be transformed into trigonocephalia, hexagon socket head, hexagonal flanged surface, a word or cross recess, hook, suspension ring, various ways such as loose joint.

Can increase the tubulose cushion block on bolt (4) and the lug bolt (5), to improve stress.

Beneficial effect of the present invention:

Through constantly bringing forth new ideas; Structure of the present invention is more succinct, and cost is lower, and then easy realization of industrialization; It has satisfied the new demand of people's application and application target and using effect; It not only can use on the porous building-brick body of wall solid and reliablely, but also is widely used on solid brick wall, cob wall, concrete structure, wooden structures, plastic construction, the closely knit soil materials such as (functions with stake) or structure, has really realized the general value of EXPANSION ANCHOR BOLTS.

Embodiment

Below in conjunction with accompanying drawing the present invention and practical implementation are described further:

Referring to accompanying drawing; Bright screw rod pattern: designed the expansion oplate that a kind of two ends are the inclined-plane (1); Two expansion oplates (1) lean against lug bolt (5) ear both sides and connect through riveting axle (2); Voussoir (6) is enclosed within that lug bolt (5) is gone up and two inclined-planes giving power and promote two expansion oplates (1) through nut (7) make it strut as scissors, and then the purpose of realization anchoring or locking.Above-mentioned lug bolt (5) is made the ears shape, and two expansion oplates (1) are inlaid between two ears.Expansion oplate (1) can be a monolithic, also can be polylith, and the best is two.The root of the ear of lug bolt (5) is provided with limited step, and expansion oplate (1) its inclined-plane when not strutting is leaned against on the limited step, inwardly rotates through limited step confined expansion plate (1).

Dark screw rod pattern: two expansion oplates (1) are inlaid between two ears of lug nut (3) and through riveting axle (2) and connect; Bolt (4) spinning is on lug nut (3); One end of bolt (4) is plane or sphere; The other end is hexagon head (8) or square toes (9), and two inclined-planes that promote two expansion oplates (1) through bolt (4) make it strut as scissors, and then reach the purpose of anchoring or locking.Expansion oplate (1) can be a monolithic, also can be polylith, and the best is two.Two basal part of the ear portions of lug nut (3) are provided with limited step, and expansion oplate (1) its inclined-plane when not strutting is leaned against on the limited step, inwardly rotate through limited step confined expansion plate (1).

The present invention provides the shape of square toes (9) in dark screw rod pattern, can square toes (9) be transformed into trigonocephalia in case of necessity, hexagon socket head, hexagonal flanged surface; One word or cross recess, hook, suspension ring, various ways such as loose joint; Through first rotation square toes (9), expansion oplate (1) scissors are strutted, reach anchoring or locking in other words earlier, and then tighten up and fixing material installed through nut (7); So, it is not only more handy, but also has enriched the light and shade pattern.

Embodiment of the present invention, the formation technique of emphasis considered component, for example: the lug nut among the present invention (3) is selected machining or smart casting for use; Or cold-heading, heat are upset; Or select section bar cutting process or the like, these all should be taken all factors into consideration according to aspects such as output, cost, material, equipment, technology, markets, what deserves to be mentioned is; If take the section bar cutting process, the embryo spare of the lug nut of shaping (3) is the embryo spare that can substitute voussoir (6).Should decide according to the market demand as for aspects such as specification of the present invention, material, surface treatment, heat treatments; For example with regard to specification; The present invention can make the conventional civilian of suitable size, also can make miniature or huge specification, to satisfy the needs of different purposes.More how conspicuous thing is not just given unnecessary details here.
