Abstract
The invention discloses a two-pin nail for fixing a shoe heel, which comprises a rectangular nail cap and nail pins, wherein the nail pins are symmetrically arranged on two short edges of the rectangular nail cap; the nail pins comprise trapezoidal blocks; an upper tapered block, a middle tapered block and a lower tapered block are sequentially arranged at the top end of each trapezoidal block from top to bottom, and the volumes of the upper tapered block, the middle tapered block and the lower tapered block gradually increase; the rectangular nail cap and the nail pins are formed into a whole; and patterns for increasing the friction coefficient are arranged on the bottom surface of the rectangular nail cap. The invention solves the problem that in the prior art, a shoe sole and a shoe heel are not connected firmly so that the shoe heel can fall off easily. In the invention, the two-pin nail is punched into the shoe sole, so that the shoe heel can be firmly jointed with the shoe sole by utilizing two triangular blocks of the two-pin nail; the invention has the advantages of simple structure and convenient use; and meanwhile, uneven patterns are arranged at two sides of the trapezoidal blocks of the nail pins, thereby increasing the friction area between the two-pin nail and the shoe heel and strengthening the friction resistance to more effectively prevent the shoe heel from loosening and falling off.
Description
Technical field
The present invention relates to a kind of double-foot nail, particularly relate to a kind of shoe double-foot nail that is used for fixing heel.
Background technology
In daily life, footwear seem particularly important as a kind of necessity; Provide for people comfortable in, also for people's foot provides safety guarantee, especially in Special Work; In industries such as army, mining industry, building industry; The work scene is very complicated, and labourer often will be at foreign material, mince, operation is carried out at scene moist, high temperature, therefore will be directly in the face of danger such as foot is wounded by stabbing, stabs, stabs, hurts, frays, burns; Wherein sole and heel are owing to directly contact with field ground; Injured maybe be the highest, labourer's job safety receives 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 through 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.
Summary of the invention
For solve in the prior art sole be connected with heel firm inadequately, the problem that comes off easily, the invention provides a kind of simple in structure, the shoe double-foot nail of can be effectively sole and heel being combined closely.
In order to achieve the above object, the technical scheme that the present invention taked 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 said rectangle head of a nail, said nail pin comprises trapezoid block; Be provided with upper conical piece, middle circular cone and inferior pyramidal piece from top to bottom successively on the trapezoid block top; The volume of said upper conical piece, middle circular cone and inferior pyramidal piece increases progressively gradually, through last three circular cones are set, has 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 said rectangle head of a nail is formed in one with the nail pin, on said rectangle head of a nail basal surface, is provided with the decorative pattern that increases coefficient of friction, increases 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 said inferior pyramidal piece is connected in, the top of said middle circular cone is connected in the bottom of upper conical piece.
The double-foot nail of above-mentioned a kind of fixing heel is characterized in that: the said rectangle head of a nail is processed by 201 stainless steel materials with the nail pin.
The invention has the beneficial effects as follows: the present invention squeezes 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; On the trapezoid block basal surface of nail pin, be provided with the decorative pattern that increases friction simultaneously, 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
Specify the present invention below in conjunction with the accompanying drawing and the specific embodiment;
Fig. 1 is a shoe double-foot nail structural representation of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with the specific embodiment, further set forth the present invention.
Embodiment:
Double-foot nail as shown in Figure 1, that this implements a kind of fixing heel comprises the rectangle head of a nail 1 and nail pin 2; On two minor faces of the rectangle head of a nail 1, be arranged with nail pin 2, 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 piece 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 said upper conical piece 6, middle circular cone 5 and inferior pyramidal piece 4 increases progressively gradually; And the bottom of circular cone 5 during the top of said inferior pyramidal piece 4 is connected in, the top of said middle circular cone 5 is connected in the bottom of upper conical piece 6.
In the present embodiment, the said rectangle head of a nail 1 is formed in one with nail pin 2.On the basal surface of trapezoid block 3, made increase bottom surface coefficient of friction, 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 said rectangle head of a nail 1 is processed by 201 stainless steel materials with nail pin 2.
This enforcement in use; The operator in heel through squeezing into double-foot nail; Heel is fixed on the sole, and the upper conical piece 6, middle circular cone 5 and the inferior pyramidal piece 4 that are about to double-foot nail are squeezed 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 invention and principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
