[0018] The technical solution of the present application will be described clearly and completely below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0019] Combine the following Figure 1-Figure 2 , describing the tire anti-skid chain provided in an embodiment of the present application.

[0020] Reference Figure 1 As shown, the tire anti-skid chain provided in the embodiment of the present application includes a restraint belt 100, a chain body 200 and an adjustment mechanism 300. The restraint belt 100 has a first end 110 and a second end 120. The restraint belt 100 is provided with connection points 130 at intervals along the length direction of the restraint belt 100; the chain body 200 is installed at the connection point 130, and the two ends of the chain body 200 are detachably connected; the adjustment mechanism 300 is arranged between the first end 110 and the second end 120, and the adjustment mechanism 300 is connected to the first end 110 and the second end 120 respectively to make the restraint belt 100 form a closed loop, and the adjustment mechanism 300 is used to adjust the circumference of the restraint belt 100 formed into a closed loop. In some specific embodiments, the restraint belt 100 is a metal belt in the shape of a mesh chain made of metal material, which can be bent under the premise of having a high structural strength; a perforation is provided on the restraint belt 100, and the two ends of the chain body 200 can be clamped at the perforation through a buckle structure. In some specific embodiments, a connecting block is welded at the perforation of the restraint belt 100. The connecting block is cylindrical. The two opposite end faces of the connecting block are respectively provided with thread grooves, and the inner side wall of the thread groove is provided with internal threads. The two ends of the chain body 200 are respectively provided with connecting heads, and the connecting heads have external threads. By making the external threads and the internal threads cooperate with each other, the two connecting heads are respectively fixed in the thread grooves at the two ends of the connecting block, so as to realize the detachable connection of the two ends of the chain body 200 and the connection between the chain body 200 and the restraint belt 100. In some specific embodiments, the restraint belt 100 includes an inner core and a coating layer. The inner core is an elastic body that can be bent into an arc shape, such as a cylindrical core made of rubber material; the coating layer is a metal chain mesh, and the coating layer is compounded on the outer surface of the inner core. In this way, the inner core helps the restraint belt 100 to form a ring after bending, so as to facilitate the installation of the anti-skid chain on the tire. The coating layer can make the restraint belt 100 have a higher structural strength and prevent the restraint belt 100 from breaking.

[0021] By using the technical solution provided by the above embodiment of the present application, by setting connection points 130 at intervals along the length direction of the restraint belt 100 on the restraint belt 100, the chain body 200 is installed at the corresponding connection points 130 respectively, and the chain body 200 can be passed over the tire bead 400 so that the chain body 200 is wrapped around the tire to form an anti-skid chain, and the installation process is simple and quick; the adjustment mechanism 300 is respectively connected to the first end 110 and the second end 120 of the restraint belt 100 so that the restraint belt 100 forms a closed loop located on the inner side of the tire, and the restraint belt 100 is adjusted by the adjustment mechanism 300. By adjusting the effective length of the belt 100 (the circumference of the closed loop formed by the restraint belt 100), the diameter of the closed loop formed by the restraint belt 100 can be changed, so that tension is generated between the restraint belt 100 and the anti-skid chain, so that the pressure between the chain body 200 and the outer side of the tire can be maintained in a suitable pressure range, and the tightness of the chain body 200 around the tire 400 can be maintained in a suitable range, thereby avoiding serious wear on the tire due to over-tightening or over-loosening while achieving a better anti-skid effect, which is beneficial to maintaining the stability of the vehicle during driving.

[0022] Reference Figure 2As shown, in some embodiments provided in the present application, the adjustment mechanism 300 includes a fixed seat 310, a movable seat 320 and a limiting assembly 330, the movable seat 320 is arranged on the fixed seat 310, and the movable seat 320 is respectively connected to the first end 110 and the second end 120, and the movable seat 320 rotates around the central axis so that part of the restraint belt 100 is wrapped around the surface of the fixed seat 310 or separated from the surface of the fixed seat 310; the limiting assembly 330 is arranged on the fixed seat 310, and the limiting assembly 330 can prevent the movable seat 320 from rotating around the central axis by abutting against the movable seat 320. In some specific embodiments, the movable seat 320 is cylindrical, and two connection grooves are provided on the outer cylindrical surface of the movable seat 320, and the two connection grooves are arranged one on the left and one on the right. A fixing ring is provided at the bottom of each connection groove, and the first end 110 and the second end 120 of the restraint belt 100 are locked on the corresponding fixing ring by buckles. The movable seat 320 can rotate to make the part of the restraint belt 100 close to the first end 110 and the second end 120 be wound on the outer cylindrical surface. In some specific embodiments, the limiting assembly 330 includes a first limiting portion and a second limiting portion, the first limiting portion is arranged on the fixed seat 310, and the second limiting portion is arranged on a side of the movable seat 320 close to the first limiting portion, and the second limiting portion and the first limiting portion are matched in a concave-convex manner. For example, the first limiting portion is a rectangular protrusion protruding from the fixed seat 310, and the second limiting portion is a rectangular groove opened on the movable seat 320. The rectangular protrusion can limit the movable seat 320 from rotating around the central axis by being clamped in the rectangular groove; when it is necessary to tighten or loosen the chain body 200, the movable seat 320 is lifted to separate the rectangular protrusion from the rectangular groove, and the movable seat 320 can be rotated. After adjusting the circumference of the restraint belt 100 to an appropriate length (adjusting the tightness of the chain body 200 to an appropriate degree), the movable seat 320 is moved down so that the rectangular protrusion is clamped in the rectangular groove, and the movable seat 320 can be circumferentially limited to prevent the movable seat 320 from continuing to rotate around the central axis.

[0023] When the movable seat 320 rotates clockwise, the movable seat 320 drives the first end 110 of the restraint belt 100 in one connecting groove and the second end 120 of the restraint belt 100 in another connecting groove to rotate clockwise together, so that the parts of the restraint belt 100 close to the first end 110 and the second end 120 are wrapped around the outer cylindrical surface of the movable seat 320, thereby reducing the effective length of the restraint belt 100; when the movable seat 320 rotates counterclockwise, the movable seat 320 drives the first end 110 of the restraint belt 100 in one connecting groove and the second end 120 of the restraint belt 100 in another connecting groove to rotate counterclockwise together, so that the restraint belt 100 wrapped around the outer cylindrical surface of the movable seat 320 is separated from the movable seat 320 again, thereby reducing the effective length of the restraint belt 100, wherein the effective length of the restraint belt 100 The degree refers to the circumference of the closed loop formed by the restraint belt 100, thereby realizing the adjustment of the diameter of the closed loop formed by the restraint belt 100; since the restraint belt 100 is located on the inner side of the tire and is connected to the chain body 200, by reducing the diameter of the closed loop formed by the restraint belt 100, the chain body 200 can be tightened toward the inner side of the tire; by increasing the diameter of the closed loop formed by the restraint belt 100, the chain body 200 can be loosened toward the outer side of the tire; in this way, the pressure between the chain body 200 and the outer side of the tire can be maintained within a suitable pressure range, and then the tightness of the chain body 200 around the tire can be maintained within a suitable range, thereby achieving a better anti-skid effect while avoiding serious wear on the tire due to over-tightening or over-loosening, which is beneficial to maintaining the stability of the vehicle during driving.

[0024] Reference Figure 2 , Figure 3As shown, in some embodiments provided in the present application, the first limiting portion includes a first gear ring 331, and the second limiting portion includes a second gear ring 332. The first gear ring 331 and the second gear ring 332 are engaged with each other to circumferentially limit the movable seat 320. Specifically, the first gear ring 331 is installed on the fixed seat 310, and the upper end face of the first gear ring 331 has a first meshing tooth 3311, and the first meshing tooth 3311 is distributed in a ring shape near the edge of the upper end face of the first gear ring 331; the second gear ring 332 is installed on the movable seat 320, and the lower end of the second gear ring 332 has a second meshing tooth 3321, and the second meshing tooth 3321 is distributed in a ring shape near the edge of the lower end face of the second gear ring 332. When the first meshing tooth 3311 and the second meshing tooth 3321 are meshed with each other, the movable seat 320 will not be able to rotate around the central axis. When the first meshing tooth 3311 and the second meshing tooth 3321 are separated, the movable seat 320 can rotate around the central axis. Specifically, from the tooth top to the tooth root, the width of the first meshing tooth 3311 and the second meshing tooth 3321 gradually increases, so that the distance between the tooth top positions of two adjacent teeth can be larger, which is beneficial to increase the probability of smooth meshing of the second meshing tooth 3321 and the first meshing tooth 3311 when the movable seat 320 rotates around the central axis to any position.

[0025] Reference Figure 3 As shown, in some embodiments provided in the present application, the limiting assembly 330 further includes a one-way bearing 333, the inner ring of the one-way bearing 333 is connected to the fixed seat 310, and the outer ring of the one-way bearing 333 is connected to the first gear ring 331. In some specific embodiments, a fixed shaft 314 is provided on the fixed seat 310, and the one-way bearing 333 is sleeved on the fixed shaft 314. The inner ring of the one-way bearing 333 and the fixed shaft 314 are clearance-matched to achieve circumferential fixation, and the outer ring of the one-way bearing 333 and the inner side wall of the first gear ring 331 are clearance-matched to achieve circumferential fixation. By providing the one-way bearing 333, the first gear ring 331 can only rotate clockwise, but not counterclockwise. In this way, when the first meshing teeth 3311 and the second meshing teeth 3321 are meshed with each other, the movable seat 320 can be rotated clockwise so that the second gear ring 332 can drive the first gear ring 331 to rotate synchronously clockwise, thereby adjusting the circumference of the restraint belt 100 without lifting the movable seat 320. After the circumference of the restraint belt 100 is adjusted to a suitable length, since the one-way bearing 333 can only rotate in one direction, the one-way bearing 333 can limit the movable seat 320 from rotating counterclockwise, thereby keeping the restraint belt 100 wound around the movable seat 320.

[0026] Reference Figure 2As shown, in some embodiments provided by the present application, the adjustment mechanism 300 further includes an elastic member 334, one end of the elastic member 334 abuts against the movable seat 320, and the other end of the elastic member 334 abuts against the fixed seat 310, and the elastic member 334 can be extended and retracted along the direction of the central axis to keep the first gear ring 331 and the second gear ring 332 meshing with each other. In some specific embodiments, the fixed seat 310 is a cylinder, and a cylindrical cavity is formed inside the movable seat 320. The movable seat 320 is disposed in the cylindrical cavity, and there is a certain distance between the inner wall of the cylindrical cavity and the outer wall of the cylinder, so that the restraint belt 100 is wound around the outer wall of the cylinder. A turning handle 323 is provided on the upper end surface of the cylinder, and correspondingly, a third through hole 313 is opened on the fixed seat 310 at a position corresponding to the turning handle 323, and the turning handle 323 can be extended from the third through hole 313, and the movable seat 320 is driven to rotate around the central axis of the turning handle 323 by rotating the turning handle 323; in some embodiments, the elastic member 334 is a spring, and the spring is sleeved on the turning handle 323, the upper end of the spring abuts against the fixed seat 310, and the lower end of the spring abuts against the movable seat 320, and the spring is squeezed by the fixed seat 310 and the movable seat 320, and under the action of the compression elastic force of the spring, the second meshing tooth 3321 and the first meshing tooth 3311 can be kept in a pressed and meshed state.

[0027] Reference Figure 2 As shown, in some embodiments provided by the present application, the movable seat 320 is cylindrical, and a first annular groove 321 and a second annular groove 322 are formed on the side of the movable seat 320. The first annular groove 321 is used to wind the portion of the restraining belt 100 close to the first end 110, and the second annular groove 322 is used to wind the portion of the restraining belt 100 close to the second end 120. Specifically, the first annular groove 321 and the second annular groove 322 are staggered in the axial direction, for example, the first annular groove 321 is arranged above the second annular groove 322. In some specific embodiments, the bottoms of the first annular groove 321 and the second annular groove 322 are respectively provided with fixing rings, the first end 110 of the restraint belt 100 is connected to the fixing ring in the first annular groove 321 by a buckle, and the second end 120 of the restraint belt 100 is connected to the fixing ring in the second annular groove 322 by a buckle. When the movable seat 320 is rotated, the portion of the restraint belt 100 close to the first end 110 can be wound in the first annular groove 321, and the portion of the restraint belt 100 close to the second end 120 can be wound in the second annular groove 322. In this way, on the one hand, it is possible to avoid the first end 110 and the second end 120 of the restraint belt 100 from overlapping when they are wound on the movable seat 320; on the other hand, by winding the restraint belt 100 in the first annular groove 321 or the second annular groove 322, it is possible to prevent the outermost side of the restraint belt 100 from contacting the inner wall of the fixed seat 310 after the thickness of the restraint belt 100 wound on the movable seat 320 increases, thereby affecting the rotation of the movable seat 320.

[0028] Reference Figure 2As shown, in some embodiments provided by the present application, the adjustment mechanism 300 further includes a first extension belt 335 and a second extension belt 336, one end of the first extension belt 335 is fixed to the bottom of the first annular groove 321, and the other end of the first extension belt 335 is connected to the first end 110; one end of the second extension belt 336 is fixed to the bottom of the second annular groove 322, and the other end of the second extension belt 336 is connected to the second end 120. Specifically, the first extension belt 335 and the second extension belt 336 are respectively connected to the restraining belt 100 through buckles. Correspondingly, the outer wall of the fixed seat 310 is provided with a first through hole 311 and a second through hole 312, the first through hole 311 and the second through hole 312 are arranged oppositely, the first through hole 311 is used to allow the first extension belt 335 / restraining belt 100 to pass through, and the second through hole 312 is used to allow the second extension belt 336 / restraining belt 100 to pass through. The first extension belt 335 and the second extension belt 336 are provided to facilitate the connection of the restraining belt 100 with the movable seat 320.

[0029] Working process of the tire anti-skid chain of the embodiment of the present application: During installation, one end of the chain body 200 is fixed to the connection point 130 of the restraint belt 100, and the other end of the chain body 200 is passed over the tire and fixed to the same connection point 130, so that the chain body 200 at all the connection points 130 is installed on the tire; The handle 323 is rotated clockwise to rotate the movable seat 320 clockwise around the central axis. Since the first meshing teeth 3311 and the second meshing teeth 3321 are meshed with each other, the first gear ring 331 drives the second gear ring 332 to rotate synchronously clockwise, and the first extension belt 335 (and the portion of the restraint belt 100 close to the first end 110) is wound in the first annular groove 321 of the movable seat 320, and the second extension belt 336 (and the portion of the restraint belt 100 close to the second end 120) is wound in the second annular groove 322 of the movable seat 320, until the effective length of the restraint belt 100 is adjusted (the tightness of the chain body 200 is adjusted to a suitable degree) to a suitable length, and the handle 323 is stopped to maintain a better tightness between the chain body 200 and the tire; When the chain body 200 and the tire need to be tightened, the handle 323 is continuously rotated clockwise until a satisfactory tightness is achieved between the chain body 200 and the tire. When the chain body 200 and the tire need to be slightly loosened, the handle 323 is pulled up to move the movable seat 320 upward, so that the first meshing teeth 3311 and the second meshing teeth 3321 are separated, and the handle 323 is rotated counterclockwise until the chain body 200 and the tire reach a satisfactory tightness. During disassembly, pull up the handle 323 to move the movable seat 320 upwards, separate the first meshing tooth 3311 from the second meshing tooth 3321, rotate the handle 323 counterclockwise to keep a relatively loose state between the chain body 200 and the tire, open the two ends of the chain body 200, separate the chain body 200 from the tire, and complete the disassembly of the tire anti-skid chain.

[0030] The tire anti-skid chain of the present application can adjust the tightness of the chain body 200, thereby ensuring that the anti-skid chain remains stable during driving. At the same time, since the length of the restraint belt 100 can be adjusted, it is suitable for tires of different sizes and different road conditions. The tire anti-skid chain of the present application has a relatively simple structure, is easy to manufacture and use, and has low repair and maintenance costs.
