Abstract

The utility model relates to a nail for woodwork, which is composed of a nail tip 1, a cylindrical nail body 2, and a nail head 3 which are integrated. The utility model is characterized in that the nail head 3 is a double-layer flat nail head with grooves in the middle. The thickness of the nail head 3 is equal to the diameter of the nail body 2. Looked at from the front face, the upper margin of the nail head is high in the middle, and is sequentially low on both sides; the lower margin is high on two sides, and is sequentially low in the middle. The flat nail head is easier to enter a piece of wood than a level nail head, and is difficult to climb out. The manufacturing material of the utility model can be aluminium alloy or engineering plastics apart from iron to overcome the reduced efficacy or ineffective state of a nail caused by iron rustiness. The woodenware using plastic nails can be modified without pulling out the nails, which saves time and timber.

Description

Snail for woodwork

The utility model relates to a kind of carpenter and uses nail.

Existing carpenter is fused and is constituted by nail point, nail body, ailhead with nail, and manufactured materials is an iron.Ailhead is flat, and anti-skidding lines is arranged above, and the cross section of nail body is circle.Because ailhead is flat, so ailhead is difficult for into wood, be difficult for paint, and the time one is long, nail is " crawling out " (promptly because use for a long time, the ailhead that causes emerge the phenomenon of timber) easily, directly influences the quality of wooden device.When reality was used, user (carpenter) generally always earlier beat flat usefulness again with ailhead, wastes time and energy for this reason.Iron can get rusty, and As time goes on will therefore reduce the effect of nail so that lost efficacy.Nail was difficult to dial and removes when woodenware need be changed a social system, and therefore may injure carpenter's apparatus as saw, plane etc.

The purpose of this utility model is as follows: ailhead is improved to chisel nail point, provides a kind of ailhead to be easy to into wood, to be difficult for " crawling out ", be convenient to paint, use nail in order to avoid the carpenter beats the carpenter of the labor of chisel nail point in use.With plastics or aluminum alloy replace iron make the carpenter with nail can the elimination time long after the iron nail effect that causes of getting rusty descend so that the defective of inefficacy, carpenter made of plastic can also be by wood working tool as processing such as saw, planes with nail, and do not injure instrument, therefore when changing a social system, woodenware need not to dial except that nail again.

The utility model is to realize like this, by the nail that nail point, nail body, ailhead fuse and constitute, the cross section of nail body for circle, nail as cylindrical body, its improvement is that ailhead changes homalocephalus into by tack, this chisel nail point is the middle two-layer stratigraphic structure that has groove, as shown in Figure 1, 2.See that from the side the thickness of chisel nail point equals the diameter of cylinder nail body.Manufactured materials also can be used the non-corrosive material instead except existing iron, comprise aluminum alloy, engineering plastics etc., thereby the nail of avoiding causing because of getting rusty lost efficacy.Adopt the plastics nail simultaneously, when woodenware transforms at need, can avoid numerous and diverse work that removes old nail of dialling, and not hinder wood working tools such as saw, plane, thereby save artificial and material.The utility model has following embodiment: 1, on the basis of existing wire nail, only the back nail head is improved to chisel nail point and the carpenter that forms uses nail; 2, the nail in the scheme 1 is used nail by the iron carpenter who changes aluminum alloy system or engineering plastics system into and form.

Carpenter for homalocephalus uses nail, because homalocephalus is easy to into wood than tack, is difficult for " crawling out ", do not hinder paint, has saved the carpenter and has used the hobnail period of the day from 11 p.m. to 1 a.m that tack is beaten work as homalocephalus earlier.When manufactured materials being changed into non-corrosive material such as aluminum alloy or engineering plastics by iron, can avoid causing because of getting rusty the effect of nail to reduce so that lost efficacy, nail made of plastic is not hindered wood working tool as saw, plane etc., thereby saves manually and timber.

Description of drawings:

Fig. 1 is the front schematic view of homalocephalus carpenter with nail, and Fig. 2 is its side schematic view then, and 1 is the nail point among the figure, and 2 are the nail body, and 3 is ailhead.

The utility model embodiment is as follows:

The homalocephalus carpenter uses nail, and ailhead 3 is a double layer, and the centre has groove, as shown in Figure 2.From the front, high in the middle of the upper limb of ailhead 3 as shown in Figure 1, reduce successively to both sides, lower edge both sides height reduces successively to the centre, and optimum shape is fan-shaped.See that from the side as shown in Figure 2, the thickness of ailhead 3 equals to follow closely the thickness of body 2, i.e. the diameter of cylinder nail body.Manufactured materials then is iron, aluminum alloy or plastics, adapting to different needs, but iron, aluminum alloy nail extrusion modling, but the molding and forming of plastics nail.Above-mentioned carpenter (contains 0.5 cun and 3 cun) with the nail total length between 0.5-3 cun.Plastics system carpenter is applicable to the spreadable life than short wooden device such as packaging box etc. with nail, and after the spreadable life finished, packaging box was easy to not hinder instrument with wood working tool processing, need not to dial except that old nail.

Claims

1, a kind of carpenter uses nail, it is by nail point 1, cylinder staple body 2 and ailhead 3 fuse and constitute, it is characterized in that ailhead 3 is the middle double layer chisel nail point that has groove, the thickness of ailhead 3 equals to follow closely the diameter of body 2, sees that from the front upper limb of ailhead 3 is middle high, reduce successively to both sides, lower edge both sides height reduces successively to the centre, is best with fan-shaped.
