Description

Technical Field

[0001] The invention relates to the technical field of anti-sinking soles, and in particular to a sole with an anti-sinking function on muddy ground. Background Art

[0002] Shoes are a tool for people to protect their feet from injury. On rainy days, the soil will become muddy, and the feet will easily sink into the mud. Existing anti-sinking shoes increase the contact surface between the sole and the mud by setting a protruding airbag component on the side of the sole to prevent the shoes from sinking. However, in daily walking, the airbag is easy to be damaged by scratching, and the friction caused by scratching can also cause the wearer to trip and affect normal walking. Therefore, designing a sole with mud anti-sinking function that can protect the side airbag and avoid scratching during daily walking has become a technical problem that needs to be solved urgently. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a shoe sole with the function of preventing from sinking into muddy ground.

[0004] The technical solution of the utility model is a sole with a mud-proof anti-sinking function, comprising an upper and a sole, wherein the sole comprises a heel portion at the rear end and receiving grooves connected to both sides of the heel portion, and the sole is also provided with a side baffle; the heel portion is provided with an elastic seesaw extending to the outside of the notch of the receiving groove, the side baffle comprises an abutment plate corresponding to the heel portion and a shielding plate matching the receiving groove, the receiving groove is provided with a closing plate at the edge of the notch of the heel portion, the ends of the elastic seesaw and the shielding plate are both provided with abutment grooves corresponding to the closing plate, and the upper and lower sides of the shielding plate are both provided with rough anti-slip surfaces; an air bag is provided on the outside of the elastic seesaw.

[0005] After adopting the above structure, the elastic seesaw is squeezed to bend into the receiving groove, driving the connected airbag to retreat into the receiving groove, and then the shielding plate is moved to make the shielding plate inserted into the receiving groove and block the outside of the airbag. The anti-slip surfaces on the upper and lower sides increase the friction between the shielding plate and the inner wall of the receiving groove. The elastic seesaw presses the shielding plate on the inside and applies force to the left and right sides of the sole. When the shielding plate is inserted into the receiving groove, the closing plate clamps the corresponding abutment groove, and the shielding plate is clamped with the force applied by the elastic seesaw to prevent the side baffle from being thrown off the receiving groove during walking. It fits well with the heel, reduces the activity space of the shielding plate, and further prevents the side shield from loosening and falling off; before walking on muddy ground, remove the side shield to make the elastic seesaw and the airbag pop out from the receiving groove, which increases the contact area when stepping on the muddy ground, reduces the pressure per unit area, and reduces the risk of sinking; because the muddy ground is relatively soft, and the resistance exerted by the muddy ground when the sole is stepped on is upward, which is perpendicular to the horizontally moving elastic seesaw, and under the elastic support of the elastic seesaw, it is not easy to be pushed back into the receiving groove by the mud, so the anti-sinking effect of the sole can be maintained during walking.

[0006] As a further improvement of the present utility model, a positioning groove is provided at the top of the shielding plate, and a movable groove corresponding to the position of the positioning groove is provided at the top of the receiving groove. A positioning block is pivotally connected in the movable groove, and an operation port is provided on one side. The bottom of the positioning block extends downward out of the movable groove, and a pushing block is provided on the side surface of the positioning block. The pushing block passes through the operation port and extends out of the movable groove.

[0007] After adopting the above structure, by pressing the pushing block to move in the operation port, the pushing block drives the positioning block to flip upward and retract into the movable groove. After the shielding plate is inserted into the receiving groove, the positioning block is pushed to flip downward and inserted into the positioning groove of the side baffle, further preventing the side baffle from falling off or being lost.

[0008] As a further improvement of the present utility model, a lifting inclined surface is provided at the bottom of the positioning block, and a reset torsion spring is connected between the positioning block and the movable groove. The lifting inclined surface faces the side where the heel part is located.

[0009] After adopting the above structure, when the shielding plate extends into the receiving groove, the lifting inclined surface is squeezed, pushing the positioning block to flip upward and enter the movable groove, and the reset torsion spring twists and accumulates elastic force; and after the positioning groove is aligned with the positioning block, the reset torsion spring exerts force to drive the positioning block to flip downward and insert into the positioning groove, using the elastic force of the reset torsion spring to prevent the positioning block from loosening upward and avoid the side baffle from falling off.

[0010] As a further improvement of the present utility model, a buffer pad is provided in the positioning groove.

[0011] After adopting the above structure, by providing a buffer pad in the positioning groove, after the reset torsion spring drives the positioning block to insert into the positioning groove, the buffer pad contacts the positioning block to decelerate, avoiding damage caused by the collision between the two.

[0012] As a further improvement of the present utility model, a plurality of horizontal anti-sinking stripes are provided on the side surface of the airbag.

[0013] After adopting the above structure, by providing a plurality of horizontal anti-sinking stripes on the side surface of the airbag, a vertical resistance is formed when the shoe sinks into the mud, slowing down the sinking speed of the shoe. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner

[0019] As Figures 1 - 4 shown, a sole with a function of preventing sinking in muddy ground includes a shoe upper and a sole. The sole includes a heel part 2 at the rear end and receiving grooves 3 connected to both sides of the heel part 2. The sole is also provided with side baffles. The heel part 2 is provided with an elastic flap 4 extending to the outside of the notch of the receiving groove 3. The side baffle includes an abutting plate 5 corresponding to the heel part 2 and a shielding plate 6 matching the receiving groove 3. The notch edge of the receiving groove 3 facing the heel part 2 is provided with a closing plate 7. Both the end of the elastic flap 4 and the end of the shielding plate 6 are provided with abutting grooves 8 corresponding to the closing plate 7. The upper and lower sides of the shielding plate 6 are both provided with rough anti - slip surfaces. An airbag 1 is arranged outside the elastic flap 4.

[0020] By squeezing the elastic flap 4 to bend it into the receiving groove 3, the connected airbag 1 is driven to retract into the receiving groove 3. Then, the shielding plate 6 is moved so that the shielding plate 6 is inserted into the receiving groove 3 and blocks outside the airbag 1. The anti - slip surfaces on the upper and lower sides increase the friction force between the inner wall of the receiving groove 3. The elastic flap 4 presses against the shielding plate 6 on the inner side, applying a force to the left and right sides of the sole. When the shielding plate 6 is inserted into the receiving groove 3, the closing plate 7 catches the corresponding abutting groove 8, and cooperates with the force applied by the elastic flap 4 to clamp the shielding plate 6, preventing the side baffle from being thrown off the receiving groove 3 during walking. The abutting plate 5 fits with the heel part 2, reducing the movement space of the shielding plate 6 and further preventing the side baffle from loosening and falling off. Before walking on muddy ground, the side baffle is removed so that the elastic flap 4 and the airbag 1 pop out of the receiving groove 3, increasing the contact area when stepping on muddy ground, reducing the pressure per unit area, and reducing the risk of sinking. Since the muddy ground is relatively soft and the resistance applied by the muddy ground when the sole is stepped on is upward and perpendicular to the horizontally moving elastic flap 4, under the elastic support of the elastic flap 4, it is not easily pushed back into the receiving groove 3 by the mud, and thus the anti - sinking effect of the sole can be maintained during walking.

[0021] The top of the shielding plate 6 is provided with a positioning groove 9. The top of the receiving groove 3 is provided with a movable groove corresponding to the position of the positioning groove 9. A positioning block 10 is axially connected in the movable groove, and an operation port 11 is provided on one side. The bottom of the positioning block 10 extends downward out of the movable groove. A pushing block 12 is provided on the side surface of the positioning block 10, and the pushing block 12 passes through the operation port 11 and extends out of the movable groove.

[0022] By moving the upper pressing push block 12 at the operation port 11, the push block 12 drives the positioning block 10 to turn upwards and retract into the movable slot. After the shielding plate 6 is inserted into the receiving slot 3, it reversely pushes the positioning block 10 to turn downwards and inserts it into the positioning slot 9 of the side baffle, further preventing the side baffle from falling off or being lost.

[0023] A lifting inclined surface 13 is provided at the bottom of the positioning block 10. A return torsion spring is connected between the positioning block 10 and the movable slot. The lifting inclined surface 13 faces the side where the heel part 2 is located.

[0024] When the shielding plate 6 extends into the receiving slot 3, it squeezes the lifting inclined surface 13, pushes the positioning block 10 to turn upwards and enter the movable slot, and the return torsion spring twists to accumulate elastic force; and after the positioning slot 9 is aligned with the positioning block 10, the return torsion spring exerts force to drive the positioning block 10 to turn downwards and insert it into the positioning slot 9, using the elastic force of the return torsion spring to prevent the positioning block 10 from loosening upwards and avoid the side baffle from falling off.

[0025] A buffer pad is provided in the positioning slot 9.

[0026] By arranging a buffer pad in the positioning slot 9, after the return torsion spring drives the positioning block 10 to insert into the positioning slot 9, the buffer pad contacts the positioning block 10 to decelerate, avoiding damage caused by their collision.

[0027] A number of horizontal anti-sinking stripes 14 are provided on the side surface of the airbag 1.

[0028] By arranging a number of horizontal anti-sinking stripes 14 on the side surface of the airbag 1, a vertical resistance is formed when the shoe sinks into the mud, slowing down the sinking speed of the shoe.
