[0031] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 9 As shown, an embodiment of the present invention provides a nail-turning chain plate for vehicle rescue, comprising a base plate 1, on which a biting block 9, a fixed protrusion structure 8 and a nail-turning rotating seat 7 are sequentially arranged at intervals along the forward direction of the vehicle, wherein the nail-turning rotating seat 7 is hinged with a nail-turning structure, and the direction of the rotating axis 3 of the nail-turning structure is perpendicular to the forward direction of the vehicle; the base plate 1 is provided with a through hole adapted to the nail-turning structure, and the nail-turning structure includes a long nail structure located below the base plate 1.

[0033] like Figure 1 As shown, the stud structure includes studs 2 arranged in parallel and stud linkage rods 5 located between the studs 2. The stud linkage rods 5 are welded to the studs 2 to achieve linkage with the studs 2. The number of studs 2 is preferably 2 to 4, and in this embodiment, the number is 2.

[0034] like Figure 2 and Figure 3 As shown, the flip pin 2 includes a hinged portion, a tilting protrusion 4 located above the base plate 1, and a long spike 14 located below the base plate 1. A mounting hole 16 is provided in the middle of the hinged portion for hinged connection with the flip pin rotating base 7. The tilting protrusion 4 and the long spike 14 are respectively connected to the hinged portion. A flip pin stopper 6 is provided on the side of the flip pin rotating base 7. The flip pin stopper 6 is located on the side near the fixed protrusion structure 8 and is used to limit the flipping protrusion 4 so that the flipping angle of the flip pin structure does not exceed 90 degrees.

[0035] In this embodiment, the stud limit block 6, stud rotating seat 7, fixed protrusion structure 8 and bite block 9 are all fixedly connected to the base plate 1 by welding. The base plate 1 is a pressure-bearing surface that bears the pressure of the vehicle tire. During the escape process, the base plate 1 is slightly warped to improve the degree of fit with the ground and the vehicle tire, thereby improving the force between "vehicle tire-stud chain plate-ground" and the stability of the stud chain plate during the escape process.

[0036] In this embodiment, the turning nail linkage rod 5 is welded to the flip protrusion 4 of the turning nail 2, which can reduce the piercing effect of the flip protrusion 4 on the vehicle tire and provide a greater degree of friction resistance between the vehicle tire and the turning nail chain plate.

[0037] like Figure 6 As shown, the side surface of the hinge portion is an arc surface, the flip protrusion 4 and the long spike 14 are respectively connected to the hinge portion through an arc transition, and the extension directions of the flip protrusion 4 and the long spike 14 are parallel and facing back to back.

[0038] like Figure 2 As shown, the spike structure includes parallel spikes 14 and a spike widening structure. The spike widening structure is used to improve the firmness and resistance to external force movement of the spikes 14 after being embedded in the ground. The spike widening structure includes a connecting plate 12 arranged between the spikes 14 and a wing plate 13 arranged on the outer side of the spike 14. The tip of the wing plate 13 is arranged at the end of the spike 14.

[0039] The wing plate 13 and the connecting plate 12 are fixed to the long nail 14 by welding. Figure 2 and Figure 3 As shown, there is a predetermined angle between the wing plate 13 and the connecting plate 12, and the predetermined angle is an obtuse angle. The wing plate 13 is set at an inclined angle to achieve the gripping and fixing effect of the flip nail structure on the part below the ground in multiple angles.

[0040] like Figure 4 As shown, the bite blocks 9 are positioned at the corners of the base plate 1 to provide an initial engagement opportunity and force for the vehicle tire to engage the spiked chain plate, thereby facilitating the tire's engagement with the spiked chain plate between the tire and the ground during the initial stages of self-rescue. Furthermore, the bite blocks 9 provide adhesion, friction, and gripping force between the tire and the spiked chain plate during the self-rescue process. There are at least two fixed protrusions 8.

[0041] In this embodiment, the nail chain plate has the function of being used independently. At the same time, one end of the base plate 1 is provided with an extension connection hook 10, and the other end is provided with an extension connection hole 11 adapted to the extension connection hook 10. Figure 7 and Figure 8 As shown, through the cooperation of the extended connecting hook 10 and the extended connecting hole 11, multiple nail chain plates can be combined to form an extended chain plate, and the tensile effect between each nail chain plate can be achieved, thereby improving the ability to escape and save oneself.

[0042] like Figure 4 and Figure 5 As shown, the extended connecting hook 10 and the bite block 9 are located at the same end of the base plate 1. The extended connecting hook 10 is located in the middle of the bite block 9 and is formed by bending the edge of the base plate 1. The extended connecting hook 10 has an anti-slip angle, and the end of the extended connecting hook 10 is provided with an anti-slip block 15 to prevent longitudinal extrusion, extrusion collapse, extrusion tilting, and hook detachment of the multi-section nail chain plate. The extended connecting hole 11 is a strip-shaped through hole. During the manufacturing process, a pair of notches are cut in the base plate 1, and the extended connecting hook 10 is hammered and bent to form the extended connecting hook 10, giving it an anti-slip angle. The anti-slip block 15 is connected to the end of the extended connecting hook 10 by welding, so that the extended connecting hook 10 has a "J"-shaped folded hook structure.

[0043] In this embodiment, the spike chain plate is made of metal materials, including but not limited to steel, cast iron, aluminum alloy, magnesium alloy and metal materials coated with a polymer layer. All edges and edges of the spike chain plate and its components are rounded or chamfered to reduce the puncture effect on vehicle tires and avoid stress concentration on the spike chain plate. In order to reduce the production cost of the spike chain plate, some structures can be replaced and produced with standard parts or substitute parts, including but not limited to using steel bars or iron rods to bend to replace the spike structure, using bolts or rods to replace the rotating shaft 3, using nuts to replace the spike rotating seat 7, and using steel bars, iron bars or other rods to replace the spike linkage rod 5, the spike limit block 6, the fixed protrusion structure 8 and the bite block 9.

[0044] The process of using the nail chain plate for vehicle rescue provided by the present invention is as follows:

[0045] When a vehicle runs off the road, falls off the curb, gets stuck, slips on sandy ground, or loses grip, the wheels spin. At this point, the tires are stopped, and one end of the spike chain plate with the biting block 9 is placed between the driving wheel's forward direction and the ground. During the placement of the spike chain plate, the spike structure below the spike chain plate does not need to be flipped open; it only needs to be attached to the lower side of the base plate 1.

[0046] Start the vehicle and start it slowly in low gear. The low-speed rotation of the driving wheel will crush the biting block 9 of the flip nail chain plate to the bottom of the wheel, so that the biting block 9 enters between the wheel and the ground, and then the flip nail chain plate moves toward the rear of the vehicle. The backward movement of the flip nail chain plate and the downward pressure of the wheel on the flip nail chain plate cause the flip nail structure to rotate relative to the base plate 1, gradually rotating from a direction parallel to the base plate 1 to a direction approximately perpendicular to the base plate 1, and gradually from Figure 3 The status shown changes to Figure 1 Status shown.

[0047] At this time, the flipping spike structure is embedded in the ground, the long spike structure penetrates deep into the ground, and the long spike widening structure and the long spike 14 jointly grip the portion below the ground to fix the flipping spike chain plate to the ground, preventing the flipping spike chain plate from moving relative to the ground, and enhancing the adhesion and grip between the flipping spike chain plate and the ground. When the flipping protrusion 4 rotates to a direction perpendicular to the base plate 1, it is fixed by the flipping spike limit block 6. The flipping protrusion 4, the flipping spike linkage rod 5, the fixed protrusion structure 8 and the bite block 9 provide friction, gripping force and locking between the flipping spike chain plate and the vehicle tire, thereby restoring the indirect grip of the wheel on the ground, thereby achieving the purpose of relying on the vehicle's own self-rescue.

[0048] Among them, for situations where long-distance rescue is required, large-area bad road conditions or vehicles are heavily loaded, multiple nail chain plates can be connected in sequence. Figures 7 to 9 As shown, the extended connection hook 10 of the upper spiked chain plate is hung in the extended connection hole 11 of the lower spiked chain plate, and one end of the base plate 1 of the upper spiked chain plate is pressed against one end of the base plate 1 of the lower spiked chain plate. According to the above operation method, the spiked chain plates are laid on the forward direction side of all the driving wheels of the vehicle. Each spiked chain plate is stretched and moved toward the rear of the vehicle under the action of the rotation of the wheel. At the same time, the downward pressure of the wheel on the spiked chain plate causes the spike structure of each spiked chain plate to be fully opened and nailed into the ground, so that each spiked chain plate has a grip on the ground.

[0049] In the above solution, the spiked chain plate is used to rescue commercial and passenger vehicles from stranded or broken-down situations, such as wheel entrapment, falling off a curb, slipping on sandy surfaces, or a lack of grip. The spiked chain plate is portable, simple in structure, easy to operate, can be operated independently by one person, is easily expandable and reusable, offers low rescue costs, is resistant to harsh conditions, and is highly adaptable.

[0050] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
