Abstract
The utility model discloses a four-pin nail for shoes for fixing heels, which comprises a rectangular nail cap and four nail pins which are arranged on the rectangular nail cap, wherein the four nail pins are respectively arranged at the four corners of the rectangular nail cap, and the rectangular nail cap and the nail pins are integrally formed; rough grains for increasing the friction coefficient are arranged on the lower surface of the rectangular nail cap, and each nail pin consists of a trapezoidal block and a tapered block; and the tapered block comprises an upper tapered block, a middle tapered block and a lower tapered block which are respectively arranged at the top end of the trapezoidal block from top to bottom and the volumes of which gradually increase. The four-pin nail is nailed into a sole, and the heel is firmly jointed on the sole by the double tapered blocks of the four-pin nail; and the utility model has simple structure and convenient use, and can effectively prevent the heel from loosening and falling off.
Description
Technical field
The utility model relates to a kind of four-foot nail, particularly relates to a kind of shoe four-foot nail of fixing heel.
Background technology
In daily life; footwear are as a kind of necessity; seem particularly important; provide for people comfortable in; also the foot for people provides safety guarantee; especially in Special Work; such as army; mining industry; in the industries such as building industry; the work scene is very complicated; labourer often will be at foreign material; mince; moist; operation is carried out at the scene of high temperature; therefore to directly be wounded by stabbing in the face of foot; stab; stab; incised wound; fray; danger such as burn; wherein sole and heel are owing to directly contact with field ground; injured may be the highest, labourer's job safety is subjected to increasing challenge, therefore the foot to labourer effectively protects being even more important of change.
And at present, in the manufacturing process of labour protection footwear, generally heel is added by various silica gel and be fixed in sole, making both interlockings is one.Yet, when people in when walking, along with falling together of step; heel and ground friction make its unsteadiness, and heel is with regard to problems such as easy generation are loosening and come off, along with heel shakes for a long time like this; impel heel and sole to break away from, influence the protection of heel sole.
The utility model content
For solve in the prior art sole be connected with heel firm inadequately, the problem that comes off easily, it is a kind of simple in structure that the utility model provides, the shoe four-foot nail of can be effectively sole and heel being combined closely.
In order to achieve the above object, technical solution adopted in the utility model is:
A kind of shoe four-foot nail of fixing heel, comprise the rectangle head of a nail and the nail pin that is arranged on the rectangle head of a nail, it is characterized in that: described nail pin is provided with four, and described four nail pin are separately positioned on four corners of the described rectangle head of a nail, and the described rectangle head of a nail and nail pin are formed in one; On the lower surface of the described rectangle head of a nail, be provided with the coarse line that is used to increase coefficient of friction, increased the coefficient of friction of rectangle head of a nail lower surface; Described each nail pin is formed by trapezoid block and circular cone, described circular cone comprises upper conical, middle circular cone and inferior pyramidal piece, described upper conical, middle circular cone and inferior pyramidal piece are separately positioned on the trapezoid block top from top to bottom, and while the volume of described upper conical, middle circular cone and inferior pyramidal piece increase progressively gradually, by three circular cones are set, strengthened the frictional resistance of nail pin, can more effectively prevent that loosening and obscission from appearring in heel.
The shoe four-foot nail of aforesaid a kind of fixing heel is characterized in that: the bottom of circular cone during the top of described inferior pyramidal piece is connected in, the top of described middle circular cone is connected in upper conical bottom.
The shoe four-foot nail of aforesaid a kind of fixing heel is characterized in that: the both sides of described trapezoid block and three circular cones all are provided with rough decorative pattern, have increased the friction area of pin nail with heel.
The shoe four-foot nail of aforesaid a kind of fixing heel is characterized in that: the described rectangle head of a nail and nail pin are made by 201 stainless steel materials.
The beneficial effects of the utility model are: the utility model is squeezed into four-foot nail at sole, utilize three circular cones of four-foot nail firm heel is fitted in sole, simple in structure, easy to use, can prevent effectively that loosening and obscission from appearring in heel, and on the lower surface of the rectangle trapezoid block that pin is followed closely, be provided with coarse line, increase the frictional force of sole bottom surface.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the utility model shoe four-foot nail structural representation.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
As shown in Figure 1, the shoe four-foot nail of a kind of fixing heel of the utility model, comprise the rectangle head of a nail 1 and nail pin 2, four corners at the rectangle head of a nail 1 are equipped with nail pin 2, nail pin 2 is made up of trapezoid block 3 and three circular cones being arranged on trapezoid block 3 tops, and these three circular cones comprise upper conical 6, middle circular cone 5 and inferior pyramidal piece 4; Upper conical 6, middle circular cone 5 and inferior pyramidal piece 4 be provided with from top to bottom trapezoid block 3 tops on, and its volume increases progressively gradually, by three circular cones are set, strengthened the frictional resistance of nail pin 2, can more effectively prevent that loosening and obscission from appearring in heel.
In the present embodiment, the bottom of circular cone 5 during the top of described inferior pyramidal piece 4 is connected in, the top of described middle circular cone 5 is connected in upper conical 6 bottom.On the lower surface of the described rectangle head of a nail 1, be provided with the coarse line that is used to increase coefficient of friction, increased the coefficient of friction of rectangle head of a nail lower surface; Be arranged on the heel bottom by the head of a nail, strengthened of the friction of heel bottom with ground.
The described rectangle head of a nail 1 and nail pin 2 are formed in one, and the described rectangle head of a nail 1 is made by 201 stainless steel materials with nail pin 2.
In addition, it should be noted that the both sides of described trapezoid block and three circular cones all are provided with rough decorative pattern, increased the friction area of pin nail with heel.
The utility model in use, the operator in heel by squeezing into four-foot nail, heel is fixed on the sole, being about to upper conical 6 of four-foot nail, middle circular cone 5 and inferior pyramidal piece 4 squeezes in sole and the heel successively, thereby both are combined closely, strengthened the frictional resistance of nail pin 2, made heel more firmly be difficult for loose or dislocation with heel.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
