As shown in fig. 1 to 4, the present embodiment relates to an emergency chain having a displacement prevention device, including a displacement prevention device 1, and a plurality of emergency chain units 2 arranged at different positions in a tire circumferential direction and bound to a tire and a hub.

The emergency chain unit 2 comprises a transition chain 21 arranged on the tire tread, a connecting piece and a locking piece 22 connected to the inner end and the outer end of the transition chain 21, and a cable tie with the end connected with the connecting piece, wherein the other end of the cable tie is connected to the locking piece 22 by bypassing a wheel hub. The technical scheme relates to an emergency chain with an anti-displacement device 1, wherein the structure and the use mode of an emergency chain unit 2 are basically the same as those of the existing emergency chain, the emergency chain unit 2 is wound and tied on a tire and a wheel hub, and a transition chain 21 needs to be arranged on the tire tread for increasing the grip force of the tire and preventing the tire from slipping. The connecting sheets and the locking sheets 22 are connected through a binding belt, the binding belt bypasses the inner wall surface of the hub, and the locking sheets 22 are used for tightly binding the binding belt to adjust the tightness. For the specific structure of the emergency chain, refer to the implementation of the scheme described in the chinese utility model patent with publication numbers "CN209869989U" and "CN201009693Y", and no description is provided herein.

On the basis, the scheme adopts the emergency chain as shown in fig. 1 and 2, and is further provided with the anti-displacement device 1, wherein the anti-displacement device 1 comprises a plurality of sections of elastic tensioning assemblies which are arranged in a radial mode and the inner ends of the elastic tensioning assemblies are connected, and the outer ends of the elastic tensioning assemblies are respectively detachably connected to the locking sheets 22 of the emergency chain units 2. The anti-displacement device 1 is arranged on the outer side of the wheel during installation, the anti-displacement device 1 is provided with a plurality of groups of elastic tensioning assemblies which are radially arranged, it can be understood that the number of the elastic tensioning assemblies is consistent with that of the emergency chain units 2, and the outer end parts of the elastic tensioning assemblies are connected to the locking sheets 22 of the emergency chain units. In this way, the elastic tensioning assembly can radially inwardly tension the locking piece 22 due to its elasticity, thereby providing a positioning in the circumferential direction of the emergency chain, so that the locking piece 22 does not move onto the tire tread during driving, as described in the background art, thereby ensuring driving safety and avoiding potential safety hazards.

In the particular embodiment shown in the figures, the elastic tensioning assembly comprises an elastic band 11 and a hook 12 attached to the outer end of the elastic band 11. The locking piece 22 is provided with a hanging opening 221, and the hook 12 can be hooked on the hanging opening 221. In this scheme, couple 12 is used for hooking on hanging the mouth 221, and the dismouting is all comparatively convenient. And the hook 12 is generally difficult to be released from the hanging opening 221 in an elastically tightened state of the elastic band 11, thereby securing a firm connection. The elastic band 11 is preferably an elastic rubber band because of its good elastic stretchability.

Based on the above scheme, the following two embodiments can be adopted to implement the following steps:

embodiment 1 referring to fig. 1, 2 and 4, two sets of elastic belts 11 of the elastic tension members are integrally connected to form an elastic cord 10, and the middle of the elastic cord 10 passes through the radial center of the tire. In the technical scheme, the two elastic belts 11 adopt the same elastic pull rope 10, that is, the elastic pull rope 10 is divided into the two elastic belts 11 by taking the middle part (the radial center of the vehicle) as a boundary, and the two elastic belts 11 are used for respectively connecting the two emergency chain units 2. The scheme has the advantages of simple structure and low construction cost, the same elastic stay cord 10 has high tensile resistance, and compared with the scheme that the inner ends of a plurality of elastic belts 11 are connected, the tensile strength of the elastic stay cord in the scheme is high.

At least two elastic cords 10 are constructed as shown in the figure, and the middle parts of the two elastic cords 10 meet at the radial center of the tire and are tied and connected by a connecting component, here shown as a rubber band connecting ring 14. The advantages of this structure are: on one hand, two or more elastic pull ropes 10 are bound together, each elastic belt 11 is radially tightened, and during work, a plurality of elastic belts 11 are radially restricted with each other, so that the situation that the stretching force of one elastic belt 11 is insufficient or over-stretched is avoided. On the other hand, based on the structure, the middle part of the elastic pull rope 10 passes through the radial center of the tire, and if the two end hooks 12 on the same elastic pull rope 10 are only arranged at 180 degrees along the radial direction of the wheel, the shape of the hub assembled by the elastic pull rope is restrained greatly. Under the scheme, the hooks 12 at two ends of the same elastic pull rope 10 can be arranged at any angle relative to the wheels, and the applicability is wide.

Embodiment 2 is schematically illustrated, but as may be suggested by the person skilled in the art: the inner ends of the elastic belts 11 of the elastic tensioning assemblies meet at the radial center of the tire and are connected through a connecting component. In this embodiment, the elastic bands 11 of each elastic tightening unit are independent of each other, and the inner ends thereof are connected to the connecting members, thereby tightening the locking pieces 22 inward in the radial direction.

In both embodiments, the hook 12 is preferably a snap hook. As shown in FIG. 3, the connecting end of the spring hook is spirally wound to form a spring ring 121, and the spring ring 121 is sleeved on the elastic band 11 and can slide along the elastic band 11. A stopper 13 for restricting the disengagement of the spring coil 121 is formed on the outer end of the elastic band 11. In this scheme, adopt the spring hook cover to locate elastic webbing 11 on the one hand, make couple 12 have certain elastic deformation ability, avoid extreme environment under couple 12 pulled apart by external force, on the other hand spring hook cover is located elastic webbing 11 and is adopted the spacing anticreep of stop part 13, can make the spring hook move along elastic webbing 11, has great dragging space. And provides a strong anti-slip limiting force without damaging the elastic band 11.

Further, the spring ring 121 of the spring hook is at least partially on the opposite side of the hook portion 122 thereof, and a notch 124 of the hook groove 123 is formed between the spring ring 121 and the hook portion 122. The hanging opening 221 is formed in the side wall of the locking piece 22, and when the spring hook is hung on the hanging opening 221, the spring ring 121 of the spring hook is located on the outer side of the end portion of the locking piece 22. That is, after the suspension, the locking piece 22 outside the hanging opening 221 is embedded in the spring hook, and therefore, the locking piece 22 is difficult to separate from the spring hook by pulling and shaking generated during use. On the other hand, in the suspended state, the spring hook abuts against the locking piece 22, and the elastic band 11 applies a radial tensile force.

As shown in fig. 4, a bent portion 111 is disposed on an outer end of the elastic band 11, and the limiting component 13 is a limiting retainer ring sleeved on the elastic band 11 and the bent portion 111 thereof. The limiting retainer ring is tightly sleeved on the elastic band 11 and the bending part 111 thereof, the inner diameter of the limiting retainer ring can be smaller than the stacking width of the elastic band 11 at the bending position, and the outer diameter of the limiting retainer ring can be larger than the minimum inner diameter of the spring ring 121, so that the elastic band 11 limits the limiting retainer ring, the limiting retainer ring limits the spring hook, and the anti-falling effect is better.

When the emergency chain with the structure is used, a plurality of emergency chain units 2 are bound at proper positions on a tire and a hub based on the shape of the hub, and then the hook 12 on the outer end part of each elastic tensioning component in the anti-displacement device 1 is clamped into the hanging opening 221 on the locking sheet 22, so that the installation is completed. Compared with the existing emergency chain, the emergency chain has the advantages that only one step is added, and the driving safety can be greatly improved.
