Abstract
The utility model discloses a two-pin nail for fixing a heel, which comprises a rectangular nail head and nail pins. Two short edges of the rectangular nail head are symmetrically provided with a nail pin, the nail pins comprise a trapezoidal block, the top ends of the trapezoidal blocks are provided with an upper tapered block, a middle tapered block and a lower tapered block in sequence from top to bottom, and the sizes of the upper tapered block, the middle tapered block and the lower tapered block increase gradually; and the rectangular nail head and the nail pins are integrated, and the bottom surface of the rectangular nail head is provided with patterns for increasing the friction coefficient. The utility model solves the problems of the prior art that the sole and the heel can not be connected firmly and can easily fall off. When the two-pin nail is knocked into the sole, the heel can be firmly attached to the sole via the two triangular blocks of the two-pin nail. The utility model has the advantages of simple structure and convenient use. Simultaneously, the two sides of the trapezoidal blocks are provided with the uneven patterns, thereby increasing the friction area between the nail and the heel, reinforcing the friction, and effectively preventing the heel from loosening and falling off.
Description
Technical field
The utility model relates to a kind of double-foot nail, particularly relates to a kind of shoe double-foot nail that is used for 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.
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 double-foot nail of the fixing heel 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 double-foot nail of fixing heel, comprise the rectangle head of a nail and nail pin, it is characterized in that: be arranged with the nail pin on two minor faces of the described rectangle head of a nail, described nail pin comprises trapezoid block, be provided with upper conical, middle circular cone and inferior pyramidal piece from top to bottom successively on the trapezoid block top, the volume of described upper conical, middle circular cone and inferior pyramidal piece increases progressively gradually, by last three circular cones are set, avoided the nail pin from heel, to come off, cross the nail pin all heel is fixed up, further increased the steadiness of heel; The described rectangle head of a nail and nail pin are formed in one, and are provided with on described rectangle head of a nail basal surface with the decorative pattern that increases coefficient of friction, increase the bottom surface frictional force of sole.
The double-foot nail of above-mentioned 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 double-foot nail of above-mentioned 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 double-foot nail at sole, utilize three circular cones of double-foot nail firm heel is fitted in sole, strengthened frictional resistance, can more effectively prevent that loosening and obscission from appearring in heel; Be provided with the decorative pattern that increases friction simultaneously on the trapezoid block basal surface of nail pin, increased the coefficient of friction of pin nail with ground, further increase the frictional force of sole, it has simple in structure, and advantage easy to use is worth of widely use.
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 double-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.
Embodiment:
As shown in Figure 1, the double-foot nail that this implements a kind of fixing heel comprises the rectangle head of a nail 1 and nail pin 2; Be arranged with nail pin 2 on two minor faces of the rectangle head of a nail 1, this nail pin 2 comprises trapezoid block 3, is disposed with three circular cones from top to bottom on trapezoid block 3 tops, and these three circular cones are upper conical 6, middle circular cone 5 and inferior pyramidal piece 4.
In three circular cones from top to bottom of trapezoid block 3 tops, the volume that is described upper conical 6, middle circular cone 5 and inferior pyramidal piece 4 increases progressively gradually, and 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.
In the present embodiment, the described rectangle head of a nail 1 and nail pin 2 are formed in one.Made increase bottom surface coefficient of friction on the basal surface of trapezoid block 3, had rough decorative pattern, this decorative pattern can be set to title or other sign of manufacturing company, has increased the coefficient of friction of bottom surface.
The described rectangle head of a nail 1 and nail pin 2 are made by 201 stainless steel materials.
This enforcement in use, the operator in heel by squeezing into double-foot nail, heel is fixed on the sole, being about to upper conical 6 of double-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.
