Description

Technical Field

[0001] The utility model relates to the technical field of snow tires, in particular to an anti-slip steel sheet for snow tires. Background Art

[0002] Snow tire anti-skid steel plates are accessories used to increase the grip and anti-skid performance of tires on snow or ice. These steel plates are usually made of high-hardness alloy steel and have a sharp serrated shape, which can form good friction on the road surface, increase the contact area between the tire and the ground, and provide better traction and braking performance. The use of snow tire anti-skid steel plates can effectively reduce the risk of vehicles slipping or skidding on snow or ice and improve driving safety. However, when using snow tire anti-skid steel plates, it should be noted that these steel plates may damage the road surface or make noise when driving on sunny days or dry roads, so it is very important to use them under appropriate road conditions. In addition, the use of snow tire anti-skid steel plates also needs to pay attention to legality and standardization to ensure compliance with relevant traffic regulations.

[0003] However, the existing anti-slip steel sheet for snow tires will be squeezed in the radial direction of the tire when it is subjected to the reaction from the ground, thereby causing irreversible cuts to the tire. At the same time, the anti-slip steel sheet will be in hard contact with the ground, causing damage to itself, thereby shortening the service life. Therefore, improvements are needed. Utility Model Content

[0004] The utility model aims to provide an anti-slip steel sheet for snow tires, which solves the problem that the existing anti-slip steel sheet for snow tires will be squeezed in the radial direction of the tire when subjected to the reaction from the ground, thereby causing irreversible cutting damage to the tire, and at the same time solves the problem that the anti-slip steel sheet will cause damage to itself due to hard contact with the ground, thereby affecting the service life.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-slip steel sheet for snow tire, comprising a tire body, an installation groove and a positioning groove are provided inside the tire body, and the installation groove and the positioning groove are communicated with each other, a protective sleeve is slidably connected to the inner side of the installation groove, an anti-slip steel sheet is fixedly connected to the inner side of the protective sleeve, a positioning plug is fixedly connected to the bottom of the anti-slip steel sheet, the positioning plug passes through the protective sleeve and extends to the outside of the protective sleeve, the positioning plug is plugged into the positioning groove, and a spring is arranged on the inner side of the installation groove.

[0006] Preferably, protrusions are fixedly connected to both left and right sides of the positioning plug, and the protrusions and the positioning plug are an integrated structure, and the protrusions are engaged with the positioning grooves. The arrangement of the protrusions has a certain damping effect on the relative sliding of the positioning plug in the positioning groove.

[0007] Preferably, a damping block is fixedly connected to the inner bottom of the positioning groove, and the damping block is slidably connected to the positioning insert. The damping block is arranged to cooperate with the positioning insert to have a certain damping effect on the anti-slip steel sheet.

[0008] Preferably, one end of the spring contacts the protective sleeve, and the other end of the spring is fixedly connected to the inner surface of the mounting groove. The arrangement of the spring has a buffering effect on the anti-slip steel sheet.

[0009] Preferably, a travel limit block is fixedly connected to the inner bottom of the installation groove, and the number of the travel limit blocks is two. The travel limit block has a limiting effect on the travel of the anti-slip steel sheet under force sliding.

[0010] Preferably, the protective sleeve is in the shape of a rectangular hollow shell and is made of rubber. The provision of the protective sleeve can prevent the anti-slip steel sheet from cutting the tire body.

[0011] The beneficial effects of the utility model are as follows:

[0012] The utility model provides an installation groove matching the outer contour of the anti-skid steel sheet on the tread of the tire body, and then plastic-coats a protective sleeve on the outer side of the anti-skid steel sheet, so as to prevent the cutting steel sheet from causing cutting injuries to the tire body when it is subjected to force. In addition, a spring is arranged in the installation groove, and a positioning plug with a protrusion is arranged at the bottom of the anti-skid steel sheet. In this way, the anti-skid steel sheet can be buffered to a certain extent when it is subjected to force through the arrangement of the positioning plug, the damping block, the protrusion and the spring, thereby improving the service life of the anti-skid steel sheet.
