Description

TECHNICAL FIELD

[0001] The utility model relates to shoe technology field especially a novel antiskid shoe sole with oil resistance and skid resistance. BACKGROUND

[0002] Now, people buy shoes no longer only consider the aesthetic degree of shoes, also consider the safety of shoes, especially the antiskid performance is particularly important. When the ground has water and other liquid medium, usually forms a liquid medium film between the shoe sole and the ground, the liquid medium film reduces the friction between the shoe sole and the ground, can say that the friction is almost zero, at this time, people are easy to slip and fall and have an accident, especially the old and the child, the security risk is big, especially in rainy day, ice and snow day, the wet and slippery degree of ground is extremely high, the security risk is big, therefore, in order to solve the foregoing problem, the prior art sets up the protruding structure on the shoe sole, the gap is formed between the protruding structure, when on the wet and slippery ground, the gap provides drainage space for liquid, avoids the liquid film between the shoe sole and the ground, improves the antiskid performance, when on the dry ground, the protruding structure has the edge structure with clear contour, the edge effect of the edge structure can improve the friction between the shoe sole and the dry ground, to improve the antiskid performance of the shoe sole, but, the structural strength of the edge structure is not high, after long-term wearing and using, the edge structure is easy to be worn by the dry ground, the edge effect disappears, the antiskid performance declines, and the antiskid practicability is low. SUMMARY

[0003] Therefore, in view of the above problems, the utility model provides a novel antiskid shoe sole with oil resistance and skid resistance with good dry skid resistance, wet skid resistance and oil skid resistance.

[0004] To solve the technical problem, the utility model adopts the following scheme: a novel antiskid shoe sole with oil resistance and skid resistance, including shoe sole body, the shoe sole body is made of butyronitrile rubber and cis-butadiene rubber and polyvinyl chloride composite plastic integrated molding, the cross section of the bottom surface of the shoe sole body is W type, and a plurality of interval setting and convex surface skid blocks are arranged on the four inclined surfaces from the heel to the toe direction, the free surface of each skid block is a plane, the inner angle of the two V type strips of the W type bottom surface of the shoe sole body extending from the heel to the toe direction is greater than 90 DEG and less than 150 DEG.

[0005] Further improvement, the skid block is a square block or a cylindrical type.

[0006] Further improvement, each skid block on the four inclined surfaces of the shoe sole body is arranged in a plurality of interval matrix.

[0007] Further improvement, the interval matrix gap between each skid block is 0.2cm-0.6cm.

[0008] By adopting the technical scheme, the novel anti-slip shoe sole with oil-resistant and anti-slip functions has the advantages that: the nitrile rubber is used as one of the main rubber materials to realize high anti-slip, the butadiene rubber is used as one of the main rubber materials to realize wear-resistant performance, and the mechanical strength of the polyvinyl chloride plastic is matched, so that the shoe sole made of the composite plastic has good dry anti-slip, wet anti-slip and oil anti-slip effects; the W-shaped cross section of the shoe sole body and the design that the inner angle of the two V-shaped strips of the W-shaped bottom surface of the shoe sole body extending from the heel to the toe is greater than 90° and less than 150° can effectively increase the contact area of the shoe sole body and the ground when the foot steps on the shoe sole body, and can effectively drain liquid to increase the friction area in the wet and slippery area, thereby achieving good anti-slip effect; the anti-slip blocks made of plastic material have self-resetting deformation performance, and can achieve micro-deformation to enhance the grip with the ground and improve the anti-slip effect on the dry surface; the anti-slip blocks are arranged in a matrix, so that the shoe sole forms a plurality of array points of large friction blocks for multi-point different direction anti-slip force, effectively improving the overall anti-slip performance of the shoe sole, and can be widely applied.
