Description

Technical Field

[0001] The utility model relates to the technical field of automobile anti-skid chains, in particular to an automobile anti-skid chain for breaking ice layers. Background Art

[0002] When a car is driving on icy roads or muddy and slippery hilly areas, the car's drive wheels need to be installed with anti-skid chains to provide the wheels with sufficient grip. Depending on the material, there are many types of anti-skid chains.

[0003] Currently, the anti-skid chains with stronger grip are those made of steel chains as the main body. However, when the wheels of the chain-like anti-skid chains travel on icy and snowy roads, the chain body itself is relatively smooth and may slip on icy and snowy roads. At the same time, the reaction force of the hard road surface on the chain will also cause reverse squeezing force on the tire, and the bulge directly on the chain head can easily cause pressure on the tire carcass, which can cause excessive pressure on the tire carcass and puncture in severe cases.

[0004] Regarding the use of ice-breaking and anti-skid chains, how to reduce the reverse squeezing force on the tire body after the ice-breaking and anti-skid chains are subjected to a large reaction force from the road surface, while providing sufficient and safe protection for the tire body, is a technical difficulty that needs to be solved. Utility Model Content

[0005] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0006] To this end, the technical solution adopted in this utility model is:

[0007] An automobile anti-skid chain for breaking ice layers, comprising a tightening mechanism and an anti-skid mechanism installed on the tightening mechanism, the tightening mechanism comprising a plurality of anti-skid chains placed horizontally and flat on the outer surface of a tire, two straps wrapped around a wheel hub, a cable connected to the straps, and a reinforcing column fixedly installed on the outside of the cable, the anti-skid mechanism comprising two fasteners installed on the outside of the reinforcing column, a fixing pin installed in the two fasteners, a positioning sleeve located outside the fixing pin and fitted between two adjacent fasteners, a chain sleeve movably connected to the two fasteners, a pressure-bearing gasket located outside the chain sleeve, and a pad installed on top of the pressure-bearing gasket.

[0008] In a preferred example, the utility model can be further configured as follows: the strap is made of wear-resistant nylon cloth, and a clamp for clamping the cable is sewn on the top of the strap.

[0009] By adopting the above technical solution, four straps are movably installed on the outside of four cables respectively, and the four straps can be wound at intervals along the outside of the wheel hub. When the four adjacent straps are tightened and bound along the wheel hub, three groups of multiple pressure-bearing pads distributed in a fan shape can be fitted to the tread of the tire for tightening.

[0010] In a preferred example, the utility model can be further configured as follows: the cable is formed by twisting and twisting a plurality of thin steel wires.

[0011] By adopting the above technical solution, two adjacent cables are welded to the outside of three reinforcing columns respectively. When the two adjacent cables are bound by two straps, the cables tightened by four straps along the wheel hub can cooperate with the reinforcing columns to provide a tightening force for the combined multiple fasteners.

[0012] In a preferred example, the utility model can be further configured as follows: the pressure-bearing gasket is an elliptical structure as a whole, and an inwardly recessed annular groove is provided on the outer side of the pressure-bearing gasket, and evenly distributed corrugated notches are provided on the bottom of the pressure-bearing gasket.

[0013] By adopting the above technical solution, the contact area between the pressure-loading pads and the pads and the tire tread is increased, and the contact surface of the corrugated groove at the bottom of the pressure-loading pads is pressed against the tire surface. When multiple pressure-loading pads rotate with the tire, the pads installed on the top of the pressure-loading pads can increase the grip when breaking ice.

[0014] In a preferred example, the utility model can be further configured as follows: three end posts adapted to penetrate into the interior of the pressure-bearing gasket are installed at the bottom of the cushion block, and holes for clamping the chain sleeve are opened inside the end posts.

[0015] By adopting the above technical solution, the end columns at the bottom of the cushion block are inserted into three vertical holes inside the pressure-bearing gasket, and the three end columns at the bottom of the cushion block are positioned and clamped in cooperation with a chain sleeve movably installed inside the pressure-bearing gasket.

[0016] In a preferred example, the utility model can be further configured as follows: the fasteners are made of stainless steel material, and the middle parts of the inner sides of two adjacent fasteners are provided with holes and grooves for clamping at the two ends of the positioning sleeve.

[0017] By adopting the above technical solution, utilizing the strength of the fasteners themselves and cooperating with the clamping of two chain sleeves by two adjacent fasteners, multiple chain sleeves movably connected by multiple fasteners can provide sufficiently stable grip for multiple pressure-bearing gaskets.

[0018] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0019] 1. The utility model arranges the chain head of the traditional single chain structure as a pressure-carrying pad with a large surface area, and opens a rough anti-skid layer on the side of the pressure-carrying pad close to the tire carcass, and installs an ice-breaking pad on the top of the pressure-carrying pad. When the pad movably installed on the top of the pressure-carrying pad is positioned and clamped by the chain sleeve, the combined multiple pressure-carrying pads and multiple pads can rotate stably in coordination with the rotation of the tire, and the pressure-carrying pad with a large contact area can reduce the reaction force from the ground on the pad. At this time, three groups of multiple pressure-carrying pads distributed in a fan shape provide anti-puncture protection to the surface of the tire, thereby ensuring the stable driving of the tire on slippery and wet roads while avoiding the problem of damage to the tire caused by the anti-skid chain being compressed.

[0020] 2. The utility model connects a plurality of transverse anti-skid chains between three adjacent groups of pressure-bearing pads. When the plurality of anti-skid chains are laid flat on the outer surface of the tire, the plurality of pressure-bearing pads distributed in a fan shape can cooperate with the plurality of anti-skid chains to provide forward and lateral anti-skid forces for the tire, thereby effectively ensuring the safety of the tire carcass when driving on the road.

[0032] Embodiment 1:

[0033] Combination Figure 1-Figure 5 As shown, the utility model provides an anti-skid chain for breaking ice layers, which includes a tightening mechanism 100 and an anti-skid mechanism 200 installed on the tightening mechanism 100.

[0034] The fastening mechanism 100 includes a strap 110 , an anti-skid chain 120 , a reinforcing column 130 and a cable 140 , and the anti-skid mechanism 200 includes a pressure-bearing gasket 210 , a chain sleeve 220 , a cushion block 230 , a fastener 240 , a positioning sleeve 250 and a positioning sleeve 250 .

[0035] Specifically, multiple anti-skid chains 120 are placed horizontally and flat on the outer surface of the tire, two belts 110 are wrapped around the wheel hub, the cable 140 is connected to the belt 110, the reinforcing column 130 is fixedly installed on the outside of the cable 140, two fasteners 240 are installed on the outside of the reinforcing column 130, the fixing pin 260 is installed in the two fasteners 240, the positioning sleeve 250 fitted between two adjacent fasteners 240 is located on the outside of the fixing pin 260, the chain sleeve 220 is movably connected to the two fasteners 240, the pressure-bearing gasket 210 is located on the outside of the chain sleeve 220, and the cushion block 230 is installed on the top of the pressure-bearing gasket 210.

[0036] By providing a rough anti-skid layer on one side of the pressure-carrying pad 210 close to the tire carcass, and installing an ice-breaking pad 230 on the top of the pressure-carrying pad 210, when the pad 230 movably installed on the top of the pressure-carrying pad 210 is positioned and clamped by the chain sleeve 220, the combined multiple pressure-carrying pads 210 and the multiple pads 230 can rotate stably in coordination with the rotation of the tire, and the pressure-carrying pad 210 with a large contact area can reduce the reaction force from the ground on the pad 230. At this time, the three groups of multiple pressure-carrying pads 210 distributed in a fan shape provide anti-puncture protection to the surface of the tire, thereby ensuring the stable driving of the tire on slippery and wet roads. When the multiple anti-side skid chains 120 are laid flat on the outer surface of the tire, the multiple pressure-carrying pads 210 distributed in a fan shape can cooperate with the multiple anti-side skid chains 120 to provide forward and lateral anti-skid force to the tire, thereby effectively ensuring the safety of the tire carcass driving on the road.

[0037] Embodiment 2:

[0038] Combination Figure 1-Figure 5As shown, on the basis of the first embodiment, the strap 110 is made of wear-resistant nylon cloth, and a clamp for clamping the cable 140 is sewn on the top of the strap 110, and the cable 140 is formed by twisting and winding multiple strands of fine steel wires.

[0039] By movably installing four straps 110 on the outside of four cables 140 respectively, the four straps 110 can be wound at intervals along the outside of the wheel hub. When the four adjacent straps 110 are tightened and bound along the wheel hub, three groups of multiple pressure-bearing pads 210 distributed in a fan shape can be fitted to the tread of the tire for tightening. As the wheel runs steadily along the ground, when two adjacent cables 140 are bound by two straps 110, the cables 140 tightened by the four straps 110 along the wheel hub can cooperate with the reinforcing columns 130 to provide a tightening force for the combined multiple fasteners 240, ultimately ensuring that the multiple pressure-bearing pads 210 will not roll over due to road resistance, and the multiple pressure-bearing pads 210 can cooperate with the pads 230 to provide anti-puncture protection for the tire and ensure that the tire will not slip.

[0040] Embodiment three:

[0041] Combination Figure 3-Figure 5 As shown, on the basis of the first embodiment, the pressure-bearing gasket 210 is an elliptical structure as a whole, and an inwardly recessed annular groove is provided on the outer side of the pressure-bearing gasket 210, and evenly distributed corrugated grooves are provided on the bottom of the pressure-bearing gasket 210, and three end columns adapted to pass through the interior of the pressure-bearing gasket 210 are installed at the bottom of the cushion block 230, and holes for clamping the chain sleeve 220 are provided inside the end columns, and the fastener 240 is made of stainless steel material, and holes for clamping the two ends of the positioning sleeve 250 are provided in the middle of the inner side of the two adjacent fasteners 240.

[0042] By increasing the contact area between the pressure-carrying pad 210 and the pad 230 and the tire tread, the contact surface of the corrugated groove at the bottom of the pressure-carrying pad 210 is pressed against the tire surface, and the end column at the bottom of the pad 230 is inserted into the three vertical holes inside the pressure-carrying pad 210, and the chain sleeve 220 movably installed inside the pressure-carrying pad 210 is used to position and clamp the three end columns at the bottom of the pad 230, so as to ensure that the pad 230 will not apply excessive extrusion force to the tire after being pressurized, and the two adjacent fasteners 240 are used to clamp the two The clamping of the chain sleeve 220 and the multiple chain sleeves 220 movably connected by the multiple fasteners 240 can provide sufficiently stable grip for the multiple pressure-loading pads 210. Finally, the multiple pressure-loading pads 210 and the multiple pads 230 tightened on the outside of the tire can increase the friction in contact with the ground. When the multiple pressure-loading pads 210 rotate with the tire, the pads 230 installed on the top of the pressure-loading pads 210 can increase the grip when breaking ice, and at the same time reduce the reaction force of the tire carcass to avoid damage to the tire.

[0043] The working principle and use process of the utility model are as follows: first, the fixing pin 260 is installed inside two adjacent fasteners 240, and the two ends of the positioning sleeve 250 movably installed outside the fixing pin 260 will respectively apply supporting force to the two fasteners 240, and the two fasteners 240 after combination can cooperate with the fixing pin 260 to provide lateral restraining force for the two adjacent chain sleeves 220, and the three end columns at the bottom of the cushion block 230 will be inserted into the three vertical holes inside the pressure-carrying gasket 210. At this time, the part of the chain sleeve 220 that penetrates to the middle of the internal horizontal hole of the pressure-carrying gasket 210 will be inserted along the holes inside the three end columns. When in use, the user can connect the combined multiple load-carrying gaskets 210 to the three vertical holes inside the pressure-carrying gasket 210. The bottom of the pressure washer 210 is placed along the outer surface of the automobile drive tire, and then the two straps 110 are passed through the gap of the wheel hub, and then the two straps 110 are bound and tightened until the combined multiple pressure-bearing pads 210 are tightened on the tire carcass. At this time, multiple anti-skid chains 120 will cooperate with three groups of pressure-bearing pads 210 to be laid flat on the surface of the tire. When the wheel is driving in contact with the ground, the multiple groups of pressure-bearing pads 210 close to the tire surface can provide a larger bearing area for the reaction force exerted on the pad 230, while reducing the pressure of the pad 230 on the rubber tire, it can also provide anti-puncture protection for the tire driving on ice and snow.
