Abstract

The utility model relates to a nail which is composed of a slim and flat cylinder whose one end is sharpened and the other end is made into an enlarged end; the cylinder of the nail is provided with at least one annular slot or a plurality of straight slots.

Description

Nail for shoe

The utility model relates to nail, particularly the shoemaking or the middle nail that uses of mending shoes.

Nail has made as a kind of securing member and has used for a long time, and in very long following period of time, what change the main structure of nail does not have yet.Its configuration of traditional nail is the enlarged that an end is shaped by cold Dun or additive method, and slender cylinder or prism that the other end is fined away.This cylinder is tapering slightly sometimes.

The purpose of this utility model is to propose a kind of improved nail, this nail in use, when particularly using as shoe tack, nail or shoe tack that its fastening force is more traditional increase significantly, and its manufacturing cost does not increase a lot.

According to the utility model, on the cylinder of traditional nail, have a cannelure at least or several are basically perpendicular to the straight trough of nail longitudinal axis.

With reference to the accompanying drawings the utility model is described in more detail.Wherein:

Fig. 1 is a side view of the utility model nail;

Fig. 2 and Fig. 3 respectively are cutaway views, the situation when expression uses nail of the present utility model to clench object;

Fig. 4 to Fig. 8 is respectively the side view of other several embodiment of the utility model.

Referring to Fig. 1.Fig. 1 represents an embodiment of the utility model nail.It comprises a cylinder 10, an end 12 and a tip 14 that enlarges, and a cannelure 16 is arranged on cylinder 10.

The operation principle of the utility model nail is described referring now to Fig. 2 and Fig. 3.Wherein 18 expressions are represented by nail object two by nail object one, 20, will be clenched by nail object 18 with nail and followed closely on the object 20.After nail hammered into, the material that constitutes object two was because its flexible effect, and inserted in the groove of being opened on the nail cylinder, thereby reached fastening effect.Traditional nail then is to reach this effect by the nail cylinder and by the frictional force between the nail object.Being example on heel with heelpiece or upper of a shoe stickfast: with reference to Fig. 2 and Fig. 3, be considered as heelpiece or upper of a shoe with 18,20 are considered as heel.Heel is generally made by rubber or wooden or other artificial compounded material, and after nail hammered into, the material that constitutes heel was owing to its flexible effect is inserted in the groove of being opened on the nail cylinder.Nail just is difficult for being pulled out like this.Thereby the fastening force of nail is increased.

Fig. 4 to Fig. 8 represents other several embodiment of the present utility model.To shown in Figure 8, the groove of leaving on the cylinder of nail can be several as Fig. 4, and these grooves can be cannelures, also can be the straight troughs that is basically perpendicular to the nail longitudinal axis.The section of groove also can be leg-of-mutton.

More than for example the utility model is described, yet should be understood that, the utility model nail is not limited in and is applied to shoe industry, and it also can be applied to other industry.

The strengths and weaknesses of the present utility model

The utility model has the advantages that: 1. than traditional nail, its fastening force is big, and lasting; 2. can be applied to shoemaking (comprise and mending shoes) industry industry in addition.

Shortcoming of the present utility model is: than traditional nail, its production cost slightly increases.

Claims

1, a kind of nail, it comprises an elongated cylinder, an end of this cylinder is fined away, and the other end is made the end of expansion, it is characterized in that having at least on the cylinder of nail a groove.
