Abstract

An anti-slip shoe cover includes shoe laces, a sole and the anti-slip needles on the sole. The anti-slip needles and the springs are arranged in around cavity of the sole and are fixed by a needle base. The laces are used to fasten the anti-slip shoes and connect to the sole solidly. The sole is turned into a three-piece fold by means of a hinge connection. Therefore, the three pieces of soles form the curve shape of the foot according to the changing angles of the foot during walking, realizing natural and comfortable walking. Inside the round cavity of the sole, the springs with proper coefficient of stiffness are arranged between the anti-slip needles and the sole, which drive the anti-slip needles penetrate into the ice by weight of human while walking on the ice, thus, preventing slipping on the ice. And, when walking on cement or bituminous streets, the anti-slip needles will withdraw into the needle base on the sole with the help of the springs, thereby serving as a buffer and shedding away uncomfortable feelings during walking, preventing anti-slip needles from getting blunt and prolonging their service life.

Description

Anti-skid overshoes

Affiliated technical field:

The utility model is to be the anti-skidding a kind of safe anti-skid overshoes that designs when walking over the ice winter.

Background technology:

Can see sole pin type anti-skid overshoes in the market, all be directly to be fixed under the sole anti-skidding pin, when walking about on ice like this, though there is not any inconvenience, when on cement or paint road, walking, because anti-skidding pin exceeds other parts, and whole body wt all is pressed on the needle point, therefore, and the easy rust of needle point not only, and in the anti-skidding sometimes pinprick route face, walking is got up also very inconvenient.

Summary of the invention:

In order to overcome existing product this defective in design, the utility model has improved the anti-skidding pin mounting means of its sole, spring and anti-skidding pin are installed on the needle stand of sole together, when walking over the ice like this, because the hardness of ice is not too big, so select suitable spring stiffness factor, can " catch " the ice face effectively, prevented in skidding on ice.And when cement or paint were walked on the road, because the road surface is very hard, anti-skidding pin was under the effect of spring, and in the indentation needle stand, sole has cushioning effect, when ice road and overland route are alternately occurred, can walk conveniently, does not have sense of discomfort.

The technical scheme that its technical problem that solves the utility model adopts is: deduct several round holes at sole part, circle hole circumferential surface cutting thread button, (perhaps round hole internal thread, needle stand external screw thread) buckled in the also corresponding cutting thread of needle stand inside diameter surface, and needle stand is fixedlyed connected in the nipple mode with sole.Spring and anti-skidding pin are packed in its circle hole, tighten on the screw buckle of sole with needle stand, the advantage that anti-skidding pin and spring are installed like this is to change spring and anti-skidding pin at any time.

The utility model beneficial effect is when the anti-skidding pin of anti-skid overshoes sole walks over the ice, to prick and play anti-skidding effect in the ice body, and the spring on the anti-skidding pin plays cushioning effect, when walking on cement or paint road, anti-skidding pin is under the effect of spring, in the indentation needle stand, the reaction force on buffer non-skid pin and road surface, when ice road and overland route are alternately occurred, promptly can walk conveniently, not have sense of discomfort, also can prevent or alleviate the rust phenomenon of anti-skidding pin, prolong the service life of anti-skidding pin.

The specific embodiment

In Fig. 1, put on anti-skid overshoes, cling with the sticky cloth on the shoestring (1), when walking on the ice face, the anti-skidding pin (4) on its sole (2) is pricked under the effect of body weight for humans power in ice sheet, stops sole (2) to skid.And set foot on cement road or paint during road, and harder because of the road surface, the spring (6) on the anti-skidding pin (4) is just had an effect, and makes in anti-skidding pin (4) the indentation circle hole (8), can produce cushioning effect like this between sole (2) and the road surface, and walking makes things convenient for.And the people is when natural walking states, and the middle part can bending phenomenon occurs for pin, and the curved shape of folding three soles this moment (2) just corresponding formation sole under hinge (5) effect is walked freely the people.

In embodiment illustrated in fig. 2, spring (6) and anti-skidding pin (4) are packed into round hole (8) afterwards, tighten mounting spring (6) and anti-skidding pin (4) with needle stand (3) screw buckle.

Claims (1)

1. anti-skid overshoes that uses on ice, under sole, spring and movable anti-skidding pin are installed in the round hole of sole together, it is characterized in that: stiffness factor appropriate spring has been installed between pushing up in the hole at anti-skidding pin with justifying.
