Abstract
The utility model discloses a multipurpose expansion screw, which is provided with an expansion pipe with a groove, and is different from the prior art that an inner sleeve with an expansion bulge at one end and an internal thread is arranged, and the inner sleeve is arranged from the end with the groove of the expansion pipe; a bolt is screwed with the inner sleeve from the other end of the expansion pipe, and when the bolt is screwed, the bolt tightens the inner sleeve towards one side of the bolt, so that one end of the expansion pipe with the groove is expanded; the bolt can be made into a standard piece or a shape with a hook or a ring at one end; the fixing plate wall can be beautiful and easy to decorate, and can be used for hanging objects, so that the fixing plate wall is multipurpose, simple and economical, and convenient to manufacture and use.
Description
The utility model relates to engineering element, specifically is anchored on the pin of the band expansion set in wall or the similarity piece.
At present, architectural general, a large amount of setscrew that uses all has expansion tube, and expansion tube one end has expansion slot; One one end band projection or ridge, the other end threaded shank is inserted in the expansion tube, one end of band projection or ridge is positioned at the end that expansion tube has groove, a nut is contained in the bolt the other end, when screwing nut, the bolt tension, the projection on the bolt is about to expansion tube trough of belt one end and struts gradually, thereby setscrew is clamped in wall, ceiling board or the similarity piece.Existing above-mentioned setscrew has following shortcoming: an end that exposes wall or ceiling board can't be made hook-type, can not hang object; The length of exposing outside is certain, can't influence beautiful decoration according to the fastening adjustings such as wooden partition of want.
The purpose of this utility model provides a kind ofly can select bolt length according to the thickness of the fastening wooden partition of want etc., and makes the setscrew of using that exposed portions serve is attractive in appearance, be beneficial to decoration more.
Technical solution of the present utility model is: a kind of setscrews of using more, has expansion tube, expansion tube one end has expansion slot, with the difference of prior art is: have one one end have the expansion projection and tapped in cover, interior cover has groove one end to pack into from expansion tube; A bolt spins from the expansion tube the other end and interior cover; When screwing bolt, bolt to the tension of bolt one side, makes expansion tube have groove one end to expand variation in interior cover.
Bolt in the utility model can adopt the standard piece bolt.
Bolt in the utility model exposes the outer end of expansion tube and can be made into hook or annular, correspondingly, can have on the bolt and screws nut.
An end that is with projection in the utility model is equipped with the standard bolt as a spare part.
Expansion tube in the utility model, interior cover, bolt can adopt No. 35 steels to make.
The utility model has the advantages that:, can be used to hang ceiling fan, pendent lamp or objects such as ceiling board decoration, mosquito net because suspension hook is arranged; When being used for fixing wallboard or ceiling board, the bolt exposed portions serve is attractive in appearance, be easy to decorate; Because bolt can adopt standard piece, no matter how much thickness of wooden partition is, can be fastening; Also can both be used for fastening ceiling board etc., be used for hanging object again, accomplish one-object-many-purposes, more economical.
The utility model is described in further detail below in conjunction with drawings and Examples:
Accompanying drawing is a kind of setscrews of using of the present utility model more.
Accompanying drawing has been described an embodiment of the present utility model.Have one one end band projection, and female in the cover 1, an end that has expansion slot 4 from an expansion tube 2 is packed into, the internal thread of the bolt 3 of buckle cover 1 in expansion tube 2 the other ends screw in, have packing ring 5, nut 6 on the bolt 3, when screwing nut 6, interior cover 1 is pulled to bolt 3 one sides, and the projection of interior cover 1 one ends is the end that dilating expansion pipe 2 has groove 4, thereby expansion tube is clamped in the impact opening.Bolt 3 buckles one end can be used to hang weight, as ceiling fan, pendent lamp etc.Screw in the standard piece bolt 7 of an adapted at interior cover 1 a bossed end.
The utility model also can change bolt 3 into the standard piece bolt, correspondingly removes nut 6, is used for wooden partition etc. is fastened on wall or the ceiling, time spent inserts whole setscrew in the impact opening, knock several down expansion tubes with hammer, make its basic fixed in the hole, put into bolt again and screw.If wooden partition thickness is bigger, the respective standard part bolt of exchangeable lengthening.
Though the utility model has increased function but be with low cost, the user is convenient, simple in structure, is easy to make and use.
