Technical field

The utility model relates to a kind of expansion nail, particularly relates to the special-purpose reverse hook type expansion of a kind of Light Wall nail.

Background technique

Due to light wall material a large amount of uses under construction, being fixed into as a difficult problem of surface of wall object.Normal screws and nail also cannot play a role in the material of eating nail ability.Existing setscrew can not be used in the softer base material of quality, and on the one hand, existing setscrew in use, need be used the special tools such as percussion drill to punch at surface of wall in advance, just can complete installation, to construction, has brought inconvenience; On the other hand, because Light Wall is eaten nail ability, setscrew is not suitable for Light Wall yet.

Model utility content

The purpose of this utility model is to provide the special-purpose reverse hook type expansion of a kind of Light Wall nail.

The purpose of this utility model is implemented by following technological scheme, the special-purpose reverse hook type expansion of a kind of Light Wall nail, it comprises nail shell and blind rivet, described nail shell comprises ailhead, rivet nut and the head of a nail, one end of described ailhead is conical nail tip, and the other end of described ailhead is conical minute core print, and the bottom surface of described conical nail tip and described taper shape divide the bottom surface of core print to be fitted and connected to be integral, described rivet nut is cylindrical shape, and the described head of a nail is ring segment; One end of described rivet nut is connected with described ailhead, within described minute, core print is placed in described rivet nut, on the described rivet nut sidewall of described minute core print both sides, is respectively equipped with two minutes core holes, the other end of described rivet nut is connected with the described head of a nail, and the inner ring surface of the described head of a nail and described rivet nut link into an integrated entity; The blind rivet head of one end of described blind rivet for matching with described minute core print, described blind rivet Tou You center is divided into two-part, the described blind rivet the other end is blind rivet cap, and the described blind rivet outer wall of described blind rivet cap one end is provided with outside thread, and the described blind rivet of described blind rivet cap one end is provided with pad and nut; Described blind rivet head inserts in described rivet nut, and makes two-part of described blind rivet head over against described minute core hole.

The sidewall of described blind rivet head is provided with locking teeth.

The outward edge of the described head of a nail is provided with the crimping being upturned.

Installation and application and principle: (1) is first knocked nail shell and entered body of wall inside to the head of a nail and surface of wall and maintain an equal level.By hook formation and the annular surface of the head of a nail, increase the area of contact of nail shell and body of wall, rivet nut steadiness is strengthened, to facilitate being driven into of blind rivet; (2) blind rivet is inserted in nail shell, blind rivet head and a minute core print for nail shell inside are interlocked, and make it can be over against minute core hole on nail shell; (3) the blind rivet cap of hammering blind rivet firmly, make blind rivet head under the acting in conjunction of the resistance of minute core print and outside impact force separately, and intert to body of wall is inner by minute core hole, to reach the friction that increases rivet nut and body of wall base material, both increased the nail ability of eating of body of wall; (4) simultaneously, the reverse hook type structure curling in body of wall by blind rivet head, and between the head of a nail, formed to the hook of body of wall even.On the main frictionally of traditional nail reaches fixedly object basis, increased again the pulling force between nail and body of wall, make fixing more firm.

The utility model has the advantage of, (1) is simple in structure, easy to use, and on Light Wall and hard, body of wall all can be used; (2) production, cheap for manufacturing cost; (3) of many uses, the huge market demand, is specially adapted to the Light Wall surface fixed objects such as hollow brick, building block brick; (4) use is flexible, specification is changeable, and ' blind rivet ' and ' nail shell ' can according to circumstances freely arrange in pairs or groups, and according to different body of wall conditions and construction requirement, selects different arranging schemes; (5) while using in soft body of wall, do not need special tool equipment, without punching in advance, easy construction, saves time; (6) during for Light Wall, fixation.
