According to the quick-release type automobile antiskid chain disclosed by the embodiment of the invention, under the action of reverse deformation elastic force, the stretched side elastic pull rope pulls the side edge chains in the adjacent cross chain assemblies to tightly wrap the edge of the side ring surface of the tire, and when the tire bursts, the side edge chains in the adjacent cross chain assemblies are pulled to tightly wrap the edge of the side ring surface of the tire; the side elastic pull ropes pull the side edge chains to be folded towards the middle along with the air leakage tire to prevent falling off, and the side elastic pull ropes can further improve the anti-falling effect that the side edge chains are folded towards the middle of the tire, and the middle elastic pull ropes can further improve the anti-falling effect that the side edge chains are folded towards the middle of the tire. The middle elastic pull rope pulls the side connecting chains to be folded towards the middle of the tire under the action of reverse deformation elastic force, and the anti-falling effect of the anti-skid chain after tire burst is greatly improved. The anti-skid chain solves the technical problem that when a vehicle tire is subjected to a tire burst shrinkage phenomenon, the anti-skid chain cannot be folded towards the tire and falls off to generate potential safety hazards.

Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobile antiskid accessories, in particular to a quick-release automobile antiskid chain. BACKGROUND

[0002] The main function of automobile antiskid chain is to improve the driving safety and stability of vehicles on ice and snow, wet and slippery road surfaces and other harsh road conditions. Specifically, antiskid chains increase the friction between the tires and the ground to prevent vehicle skidding or loss of control, thereby improving the driving stability of vehicles. Antiskid chains are widely used in various scenarios, not only in winter but also in muddy and wet conditions. However, since antiskid chains are simply wrapped around the tire side ring, they cannot follow the deflated and contracted tire when a tire blowout occurs. At this time, the antiskid chain is no longer in close contact with the tire side ring, and the antiskid chain will fall off the tire during the vehicle's continued forward movement. The falling antiskid chain may cause accidents such as flying onto the road or winding around the wheel shaft, posing a safety threat to surrounding vehicles and increasing the difficulty of subsequent vehicle maintenance.

DETAILED DESCRIPTION

[0031] The present application will now be described more fully hereinafter with reference to the accompanying drawings, in which currently preferred embodiments of the application are shown. The application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and fully convey the scope of the application to the skilled person.

[0032] Example 1, a quick-release type automobile anti-skid chain, hereinafter referred to as the anti-skid chain, like Figures 1-8As shown, it comprises middle connecting chain 11, positioning rod 111, middle edge chain 12, cross chain assembly, side elastic pull rope 23, first steel wire rope 31, plug 32, first fixed shell 33, first winding wheel 34, knob 35, double ratchet ring 36, first compression spring 361, pressing block 37, single-toothed ratchet 38 and spring 39; the front end and the rear end of the middle connecting chain 11 are each fixedly connected with a middle edge chain 12; the middle part of the middle connecting chain 11 is fixedly connected with the positioning rod 111 as the center positioning, and the positioning rod 111 is coated with a red coating as a mark; the left end and the right end of the two middle edge chains 12 are respectively provided with a plurality of cross chain assemblies, and the left end of the middle edge chain 12 is fixedly connected with the first cross chain assembly on its left side, the right end of the middle edge chain 12 is fixedly connected with the first cross chain assembly on its right side, and the left and right ends of the middle edge chain 12 are respectively fixedly connected with the first cross chain assemblies on its left and right sides; every two adjacent cross chain assemblies are connected by two side elastic pull ropes 23 respectively, and the two side elastic pull ropes 23 are respectively located on the front side and the rear side of the cross chain assembly; two first steel wire ropes 31 are connected on the first cross chain assembly on the left end, and the two first steel wire ropes 31 are respectively located on the front side and the rear side of the cross chain assembly; one plug 32 is welded on each of the two first steel wire ropes 31; two first fixed shells 33 are connected on the first cross chain assembly on the right end, and the two first steel wire ropes 31 are respectively located on the front side and the rear side of the cross chain assembly; one inlet port structure 3301 is formed in each of the two first fixed shells 33; one first winding wheel 34 is rotatably connected in each of the two first fixed shells 33; one insertion hole structure 3401 is formed in each of the two first winding wheels 34, and the insertion hole structure 3401 is initially aligned with the inlet port structure 3301 of the corresponding first fixed shell 33; one knob 35 is fixedly connected to each of the two first winding wheels 34; one double ratchet ring 36 is rotatably connected in each of the two first fixed shells 33; one first compression spring 361 is fixedly connected between each of the two double ratchet rings 36 and the corresponding first fixed shell 33; one pressing block 37 is fixedly connected to each of the two double ratchet rings 36; a plurality of single-toothed ratchets 38 cooperating with the double ratchet ring 36 are rotatably connected to the first winding wheel 34 through the rotating shaft; one spring 39 is fixedly connected between each single-toothed ratchet 38 and the first winding wheel 34.

[0033] As Figure 1 , Figure 2 and Figure 4As shown, the cross chain assembly is composed of chain component connection groups that are transversely and longitudinally staggered, specifically including side edge chains 21 and side connecting chains 22; the side connecting chains 22 are fixedly connected between two side edge chains 21; in each adjacent cross chain assembly, the two side edge chains 21 that are adjacent to each other are connected by a same side elastic pull rope 23; the two side edge chains 21 in the left end first cross chain assembly are fixedly connected with a corresponding first steel wire rope 31 respectively; the two side edge chains 21 in the right end first cross chain assembly are fixedly connected with a corresponding first fixed shell 33 respectively; the two side edge chains 21 of the left end first cross chain assembly on the left side of the middle connecting chain 11 and the two side edge chains 21 of the right end first cross chain assembly on the right side of the middle connecting chain 11 are fixedly connected with a corresponding middle edge chain 12 respectively.

[0034] As shown in the figure, Figure 8 As shown, the bottom of each side connecting chain 22 is fixedly connected with a plurality of anti-skid pads 24; the anti-skid pads 24 not only reduce the extrusion force generated when the side connecting chain 22 is tightly attached to the tire side surface, but also improve the anti-skid effect of the side connecting chain 22 on the tire side surface, preventing the side connecting chain 22 from loosening, sliding and deviating on the tire side surface; the bottom of each anti-skid pad 24 is provided with a plurality of anti-skid convex structures 2401; the anti-skid pad 24 is firmly attached to the tire side surface pattern structure through the anti-skid convex structures 2401 at the bottom, further enhancing the anti-skid effect of the side connecting chain 22 on the tire side surface.

[0035] In this embodiment, when the driver installs the anti-skid chain, first, the anti-skid chain is unfolded and placed above the tire side ring surface, the positioning rod 111 of the middle connecting chain 11 is placed in the middle area of the top of the tire side ring surface, and then the left and right cross chain assemblies are respectively arranged on the left and right sides of the tire side ring surface. At the same time, the driver pulls the cross chain assembly to stretch the side elastic pull rope 23 downward, so that the side elastic pull rope 23 is in a stretched state. The side elastic pull rope 23 exerts a reverse pulling force on the cross chain assembly, so that the side connecting chain 22 of the cross chain assembly is in close contact with the tire side ring surface, and the side edge chain 21 is in close contact with the edge of the tire side ring surface. Then, the two first steel wire ropes 31 connected to the left end of the first cross chain assembly and the two first fixed shells 33 connected to the right end of the first cross chain assembly are respectively aligned on the bottom front side and the bottom rear side of the tire. The driver inserts the plug 32 on the first steel wire rope 31 into the insertion hole structure 3401 of the first winding wheel 34 through the inlet port structure 3301 of the first fixed shell 33. The driver rotates the knob 35 to continuously wind the first steel wire rope 31 on the first winding wheel 34. At the same time, the single-tooth ratchet 38 driven by the first winding wheel 34 cooperates with the spring 39 to continuously pass through the tooth groove structure of the double ratchet ring 36. The double ratchet ring 36 provides a fixed support for preventing reverse rotation of the first winding wheel 34 through the single-tooth ratchet 38, so that the first steel wire rope 31 is tightly locked on the first winding wheel 34. Thus, the left end and the right end of the anti-skid chain are tightly locked together, and the installation of the anti-skid chain on the tire is completed.

[0036] After the anti-skid chain is installed on the tire, the two side edge chains 21 adjacent to each other on the two adjacent cross chain assemblies are connected by the side elastic pull rope 23. The two side edge chains 21 are stretched by the side elastic pull rope 23. Under the action of the reverse deformation elastic force, the two side edge chains 21 are pulled to tightly wrap around the tire side ring surface. When the tire bursts, the deflated tire contracts towards the middle. At the same time, the side elastic pull rope 23 pulls the two side edge chains 21 to contract towards the middle under the action of the reverse deformation elastic force, so that the side edge chain 21 tightly wraps around the tire side ring surface. At the same time, the middle elastic pull rope 26 pulls the two side connecting chains 22 to contract towards the middle under the action of the reverse deformation elastic force, so that the side connecting chain 22 tightly wraps around the tire side ring surface. This improves the anti-falling effect of the anti-skid chain after the tire bursts, and avoids accidents caused by the anti-skid chain falling off.

[0037] In the subsequent disassembly work, the driver only needs to press the pressure block 37 to push the double ratchet ring 36 to drive the first compression spring 361 to compress, so that the double ratchet ring 36 leaves the single toothed ratchet 38 on the first winding wheel 34 and no longer provides fixed support to it. At this time, the stretched side elastic pull rope 23 will automatically pull the cross chain assembly to drive the first steel wire rope 31 to be released from the first winding wheel 34, and then the anti-skid chain can be removed from the tire, realizing the quick disassembly of the anti-skid chain.

[0038] As shown in the above embodiment 1, a plurality of first hooks 41 are welded on the two side edge chains 21 of the second cross chain assembly at the left end and the second cross chain assembly at the right end. Figures 1-8

[0039] In this embodiment, during the process of the driver sleeving the anti-skid chain on the tire, the driver first stretches the side elastic pull rope 23 by the two adjacent side edge chains 21, and the stretched side elastic pull rope 23 pulls the two adjacent side edge chains 21 to tightly wrap around the side surface of the tire under the action of the reverse deformation elastic force. Then the driver stretches the left side elastic pull rope 42 to the right and down, and the clasp 43 on the left side elastic pull rope 42 is hung on any right first hook 41 to the right and down. The right side elastic pull rope 42 is stretched to the left and down, and the clasp 43 on the right side elastic pull rope 42 is hung on any left first hook 41 to the left and down, so that the two side elastic pull ropes 42 on the same side are crossed and tightly wrapped around the outside of the tire in the stretched state. When the tire bursts, the deflated tire contracts to the middle, and the two adjacent side edge chains 21 are pulled by the side elastic pull rope 23 under the action of the reverse deformation elastic force, so that the side edge chains 21 remain tightly wrapped around the side surface of the tire, and the side elastic pull ropes 42 pull the two connected side edge chains 21 to contract towards the middle of the tire, further improving the anti-falling effect of the side edge chains 21 contracting towards the middle of the tire. In addition, the disassembly work can be quickly completed by pulling the side elastic pull rope 42 to remove the clasp 43 from the first hook 41.

[0040] As shown in the above embodiment 1, a plurality of first hooks 41 are welded on the two side edge chains 21 of the second cross chain assembly at the left end and the second cross chain assembly at the right end. Figures 1-10 ​As shown, on the basis of the above embodiment 1, two side connecting chains 22 are commonly fixed between two side edge chains 21 in each cross chain assembly of the present embodiment; a short chain 25 is commonly fixed between the middle portions of the two side connecting chains 22 in each cross chain assembly, and the two side connecting chains 22 in the same cross chain assembly are connected into a whole through the short chain 25, which not only strengthens the structural strength of the two side connecting chains 22, but also increases the number of side connecting chains 22 and enhances the anti-skid performance provided for the tire; a middle elastic pull rope 26 is commonly fixed between the middle portions of the two side connecting chains 22 which are adjacent to each other on each adjacent two cross chain assemblies; the middle elastic pull rope 26 is provided as a quick-release type connecting assembly, which is composed of a fixed end head 261, a threaded rod 262 and an elastic rope 263; one fixed end head 261 is fixed on each of the two side connecting chains 22 which are adjacent to each other on each adjacent two cross chain assemblies; one threaded rod 262 is screwed and fixed in each of the two fixed end heads 261 through a threaded structure; and the elastic rope 263 is commonly fixed between the two threaded rods 262.

[0041] In the present embodiment, the two side edge chains 21 which are adjacent to each other on each adjacent two cross chain assemblies are connected through the side elastic pull rope 23, and after the present anti-skid chain is sleeved on the tire, the two side edge chains 21 which are adjacent to each other commonly stretch the side elastic pull rope 23, and the side elastic pull rope 23 which is stretched pulls the two side edge chains 21 which are adjacent to each other to tightly wrap around the side edge of the tire under the action of the reverse deformation elasticity; the two side connecting chains 22 which are adjacent to each other on each adjacent two cross chain assemblies are connected through the middle elastic pull rope 26, and after the present anti-skid chain is sleeved on the tire, the two side connecting chains 22 which are adjacent to each other commonly stretch the middle elastic pull rope 26, and the middle elastic pull rope 26 which is stretched pulls the two side connecting chains 22 which are adjacent to each other to tightly wrap around the middle of the tire under the action of the reverse deformation elasticity, thereby improving the tight anti-skid effect of the present anti-skid chain when sleeved on the tire; when the tire is in the situation of blowout, the deflated tire shrinks to the middle, and at the same time, the side elastic pull rope 23 pulls the two side edge chains 21 which are adjacent to each other to shrink to the middle along with the deflated tire under the action of the reverse deformation elasticity, so that the side edge chains 21 remain in the state of tightly wrapping around the side edge of the tire, and at the same time, the middle elastic pull rope 26 pulls the two side connecting chains 22 which are adjacent to each other to shrink to the middle along with the deflated tire under the action of the reverse deformation elasticity, so that the side connecting chains 22 remain in the state of tightly wrapping around the middle of the tire, thereby greatly improving the anti-falling effect of the present anti-skid chain after the tire is in the situation of blowout.

[0042] Furthermore, since the side elastic cord 23 and the central elastic cord 26 are both tightly wrapped around the middle of the tire's sidewall surface, the central elastic cord 26 will continuously contact the ground during tire operation. As the tire's mileage increases, the wear caused by the central elastic cord 26 contacting the ground will gradually increase. When the driver finds severe wear on the central elastic cord 26 during regular inspections of this snow chain, it is necessary to replace the central elastic cord 26. In the initial unfolded state before the snow chain is installed on the tire, simply remove the threaded rods 262 at both ends of the elastic cord 263 in the central elastic cord 26 from the two fixed ends 261 to quickly complete the quick-release work of the elastic cord 263. Then, connect the threaded rods 262 at both ends of the new elastic cord 263 to the two fixed ends 261 to quickly complete the replacement of the elastic cord 263 in the central elastic cord 26.

[0043] Example 4, as Figures 11-13 As shown, this embodiment of a quick-release car snow chain includes a central connecting chain 11, a central side chain 12, cross chain assemblies, and side elastic pull ropes 23. The difference between this embodiment and Embodiment 1 is that this embodiment further includes hooks 51, a second fixing shell 52, a second winding wheel 53, a torsion spring 54, a second wire rope 55, a hanging plate 56, a single ratchet ring 57, a multi-tooth ratchet 58, a second compression spring 581, a button 59, and a third compression spring 591. A central side chain 12 is fixedly connected to the front and rear ends of the central connecting chain 11. Several cross chain assemblies are respectively provided at the left and right ends of the central side chain 12. Adjacent cross chain assemblies are connected by two side elastic pull ropes 23. Two hooks 51 are connected to the first cross chain assembly at the left end; the first cross chain assembly at the right end... The upper part is connected to two second fixed housings 52; each of the two second fixed housings 52 is rotatably connected to a second winding wheel 53; each of the two second winding wheels 53 is fixedly connected to a torsion spring 54 between it and the corresponding second fixed housing 52; each of the two second winding wheels 53 is wound with a second steel wire rope 55; each of the two steel wire ropes 55 is fixedly connected to a hanging plate 56; each of the two second winding wheels 53 is fixedly connected to a single ratchet ring 57; each of the two second fixed housings 52 is rotatably connected to a multi-toothed ratchet 58; each of the two multi-toothed ratchets 58 is fixedly connected to a second compression spring 581 between it and the corresponding second fixed housing 52; each of the two second fixed housings 52 is slidably connected to a button 59 that is in close contact with the multi-toothed ratchet 58; each of the two buttons 59 is fixedly connected to a third compression spring 591 between it and the corresponding second fixed housing 52.

[0044] The usage steps in this embodiment differ from those in Embodiment 1 as follows.

[0045] When the driver installs the anti-skid chain, first, the driver places the anti-skid chain on the tire side ring surface according to the steps of Embodiment 1, and at the same time, the driver pulls the cross-chain assembly to stretch the side elastic pull rope 23 downward, so that the side elastic pull rope 23 exerts a reverse pulling force on the cross-chain assembly, the side connecting chain 22 of the cross-chain assembly is in close contact with the tire side ring surface, and the side edge chain 21 is in close contact with the edge of the tire side ring surface. Then, the two hooks 51 on the left end of the first cross-chain assembly are aligned with the two hook plates 56 on the right end of the first cross-chain assembly at the bottom of the tire on the front side and the rear side, respectively. The driver pulls the hook plate 56 to pull the second steel wire rope 55 out of the second winding wheel 53, and at the same time, the second winding wheel 53 and the single ratchet ring 57 are driven to rotate forward by the second steel wire rope 55. The single ratchet ring 57 rotates forward and can smoothly pass through the multi-tooth ratchet 58, and the multi-tooth ratchet 58 blocks the reverse rotation of the single ratchet ring 57. At the same time, the second winding wheel 53 drives the torsional spring 54 to twist. After the driver hangs the hook plate 56 on the corresponding hook 51, the driver presses the button 59 to drive the third compression spring 591 to compress, and at the same time, the button 59 drives the multi-tooth ratchet 58 to rotate away from the single ratchet ring 57. At the same time, the single ratchet ring 57 drives the second compression spring 581 to compress, so that the multi-tooth ratchet 58 no longer blocks the reverse rotation of the single ratchet ring 57. At the same time, the twisted torsional spring 54 drives the second winding wheel 53 to rotate reversely to reset. The second winding wheel 53 winds the second steel wire rope 55, and the second steel wire rope 55 locks the hook 51 tightly through the hook plate 56, so that the left end and the right end of the anti-skid chain are locked and fixed together, and the installation of the anti-skid chain on the tire is completed.

[0046] After the anti-skid chain is installed on the tire, when the tire is punctured, the side elastic pull rope 23 pulls the adjacent two side edge chains 21 to gather in the middle under the action of the reverse deformation elastic force, and at the same time, the middle elastic pull rope 26 pulls the adjacent two side connecting chains 22 to gather in the middle under the action of the reverse deformation elastic force, so that the anti-skid chain does not fall off and causes an accident.

[0047] In the subsequent disassembly work, the driver only needs to pull the hook plate 56 to pull the second steel wire rope 55 out of the second winding wheel 53, and then remove the hook plate 56 from the hook 51, and then remove the anti-skid chain from the tire, so as to quickly complete the disassembly of the anti-skid chain.

[0048] The above is only the preferred embodiment of the present application, and it should be pointed out that those skilled in the art can make some improvements and refinements without departing from the principles of the present application, and these improvements and refinements should be regarded as the protection scope of the present application.
