Abstract

The utility model relates to an expanding rivet, belonging to a pin or other elements fixed on the wall or the similar elements. A main body is composed of a rivet cap, a half column-shaped rivet rod, and a half column-shaped inserting sheet. The rivet cap is fixed to the tail end of the half column-shaped rivet rod, and the front part of the half column-shaped rivet rod is a sloping portion. A semicircle-shaped through hole is arranged on the rivet cap in order that the half column-shaped inserting sheet can be inserted into the semicircle-shaped through hole and the half column-shaped inserting sheet can form a column with the half column-shaped rivet rod. The utility model solves the problems of the prior art of the complicated manufacture and complicated installation, and has the advantages of convenient operation, simply operation, and practicability.

Description

Expanding revet

A kind of expandable nail relates to the pin or other devices that are anchored in wall or the similarity piece.

The existing fixed expansion body that is used on building decoration, household electric appliance installation and the various wall generally is expansion of metal screw or plastic expansion nail.But in manufacturing and using process, exist complex structure, consume the shortcoming that raw material is more, tired lock is installed.Especially when the expansion of metal screw is installed, adopt the mode of tightening nuts to make indirect expansion of pipe reach fastening purpose, so operating process is slow.And have part nut, screw rod to be exposed after installing, and collude easily to prick and get rusty, influence other article.To plastic expansion, because of leaning on indirect securement, so exist the defective of tensility difference.

The utility model is at the existing in prior technology defective, provides that a kind of novel structure is simple, materials are economized, easy and simple to handle, attractive in appearance, practical, expandable nail that tensility is good.

For achieving the above object, the utility model adopts such technological scheme: the tail end of semicolumn staple bar is fixed with the head of a nail, has semicircle on the head of a nail and cooperates through hole.When semi-cylindrical movable inserted sheet cooperates through hole to insert from semicircle, form a cylindrical body with semicolumn staple bar.The front portion of semicolumn staple bar is the inclination position.When the half-cylindrical movable inserted sheet that cooperates through hole to be knocked in from semicircle was inserted into the inclination position, its end produced expansion.

The utility model compared with prior art, not only novel structure is simple, and the 40K that can save material.Because employing activity piece insertion type structure so expandable nail is put into the good Kong Zhonghou of brill, only needs fullering tool hammering activity inserted sheet can play fastening effect.It also has easy and simple to handle, practical wide, bright and clean, the beautiful and comfortable advantage in dress rear surface simultaneously.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model example structure schematic representation.

Fig. 3 is another example structure schematic representation of the utility model.

Below in conjunction with drawings and Examples the utility model is described.

Referring to Fig. 1, main body of the present utility model is made of semicolumn staple bar (2), the head of a nail (1) and half-cylindrical movable inserted sheet (3).The head of a nail is fixed on the tail end of semicolumn staple bar, is an overall structure with described nail bar preferably.And have on the head of a nail and semicircle cooperate through hole (4), match with the planar section of semicolumn staple bar so that from then on half-cylindrical inserted sheet inserts in the hole, thereby form a cylindrical body.The front portion of semicolumn staple bar is inclination position (5).Specifically, just there is constant slope the front portion of semicolumn staple bar planar section, but the cylndrical surface part does not tilt.When half-cylindrical inserted sheet inserted from the semicircle matching hole and knocked the inclination position, change to a certain degree will take place in its moving direction, promptly moves along the inclined-plane.Therefore produce at the cylinder front end that constitutes by semicolumn staple bar and half-cylindrical inserted sheet and expand, and play fixation thus.

Referring to Fig. 2, on structure shown in Figure 1, increase a fixed plate (6).One center hole (7) and two screw holes (8) are arranged on the fixed plate.Fixed plate is enclosed within on the cylinder of being made up of semicolumn staple bar (2) and half-cylindrical inserted sheet (3) by center hole.Fixed plate is fixed between the wall and the head of a nail (1) during use, and can be in the screw of fixed plate DRIVE SCREWS.Referring to Fig. 3, on the head of a nail, be processed with tapped hole (9) again, an end of hook (10) can be screwed in wherein.

Claims (3)

1, a kind of expandable nail relates to the device that is anchored in wall or the similarity piece, includes the head of a nail, semicolumn staple bar, and it is characterized in that: the tail end of a. semicolumn staple bar is fixed with the head of a nail, and anterior is the inclination position; B. have semicircle on the described head of a nail and cooperate through hole, half-cylindrical movable inserted sheet inserts from described through hole, and cooperates the formation cylindrical body with semicolumn staple bar.

2, expandable nail according to claim 1 is characterized in that the fixed plate that has screw and center hole is enclosed within on the cylinder that is made of movable inserted sheet of half round post and semicolumn staple bar by described center hole.

3, expandable nail according to claim 1 is characterized in that having screw on the described head of a nail.
