Description

Dustproof insole

technical field

The utility model relates to an anti-pollution insole, in particular to a dust-proof insole which can prevent the dust on the sole from polluting the floor.

Background technique

At present, the known method for preventing sole dust from polluting the floor is to use plastic shoe covers, but disposable plastic shoe covers are both wasteful and unattractive, and discarded plastic shoe covers also pollute the environment.

Contents of the invention

In order to overcome the waste and pollute the environment of the existing disposable plastic shoe covers, the utility model provides a dust-proof insole, which can prevent the dust on the sole from polluting the floor and can be used repeatedly, so it is energy-saving and environment-friendly.

The technical scheme that the utility model solves its technical problem adopts is: the utility model comprises shoe-pad, dust-proof limit, left splint, right splint, handle, rotating shaft, lock ring, coupling head and buckle.

The insole is a flat plate structure matching the shape of the foot. A shaft hole is opened on the transverse central axis of the insole, and an upwardly protruding dust-proof edge is provided along the periphery of the upper surface of the insole. The insole and the dust-proof edge are made of elastic materials. The left splint is an arc-shaped plate structure that bends to the right, and the right splint is an arc-shaped plate structure that bends to the left. Both the left splint and the right splint are made of elastic materials, and handles are arranged on the upper ends of the left splint and the right splint. The lock ring has a ring structure, the lock ring is made of elastic material, and a coupling head protruding downward is arranged on the outer wall of the lower end of the lock ring. The rotating shaft is arranged in the shaft hole of the insole, the left shaft end of the rotating shaft is connected with the lower end of the left splint, the right shaft end of the rotating shaft is connected with the lower end of the right splint, the upper end of the left splint is arranged alternately with the upper end of the right splint, the left The handle on the splint is located on the right side of the longitudinal central axis of the insole, and the handle on the right splint is located on the left side of the longitudinal central axis of the insole. A nail hole is provided on the left side of the longitudinal central axis of the insole on the left splint, and a nail hole is provided on the right side of the longitudinal central axis of the insole on the right splint. The lock ring is set between the left splint, the right splint and the insole. The coupling head on the lock ring passes through the insole to connect with the shaft body of the shaft. The left and right ends are connected.

When using, squeeze the left and right handles, when the left and right handles respectively drive the left and right splints to deflect left and right around the shaft, the left and right splints can open the lock ring through the left and right buckles, You can now put the front of the shoe through the lock ring and place the shoe on the insole. When the left and right handles are released, the left splint and the right splint can clamp the shoes under the effect of elastic force, and the lock ring will also hold the shoe firmly under the effect of elastic force.

The beneficial effect of the utility model is that it can prevent the dust on the sole from polluting the floor and can be used repeatedly, so the shoe is energy-saving and environment-friendly.

Detailed ways

In Fig. 1, Fig. 2, Fig. 3, Fig. 4, and Fig. 5, the insole 1 is a flat plate structure matching the shape of the foot, and a shaft hole is opened at the transverse central axis of the insole 1, and is arranged along the periphery of the upper surface of the insole 1. There is an upwardly protruding dustproof edge 7, and the insole 1 and the dustproof edge 7 are made of elastic material. The left splint 2 is an arc-shaped plate structure that bends to the right, and the right splint 6 is an arc-shaped plate structure that bends to the left. Both the left splint 2 and the right splint 6 are made of elastic materials. The heads are all provided with handles 3 . The lock ring 8 has a ring structure, and the lock ring 8 is made of an elastic material. On the outer wall of the lower end of the lock ring 8, a coupling head 9 protruding downward is provided. The rotating shaft 5 is arranged in the shaft hole of the insole 1, the left shaft end of the rotating shaft 5 is connected with the lower end of the left splint 2, the right shaft end of the rotating shaft 5 is connected with the lower end of the right splint 6, and the upper end of the left splint 2 is connected with the right splint The upper ends of 6 are arranged in a staggered manner, the handle 3 on the left splint 2 is positioned at the right side of the longitudinal central axis of the shoe-pad 1 , and the handle 3 on the right splint 6 is positioned at the left side of the longitudinal central axis of the shoe-pad 1 . A nail hole is provided on the left side of the longitudinal central axis of the insole 1 on the left splint 2 , and a nail hole is provided on the right side of the longitudinal central axis of the insole 1 on the right splint 6 .
