However, when the connecting belt is connected to the tire for a long time, the connecting belt is prone to loosening between the tire, which also causes the connecting belt to deviate on the tire surface with the movement of the tire. The anti-skid effect of the deviated anti-skid belt will be reduced. Now the anti-skid belt is connected to the vehicle tire, and then the adjusting belt on the connecting block is connected to the clamping plate through the tire, and then the adjusting belt is stretched into the connecting groove of the connecting plate, and the screw is rotated to drive the adjusting block and the connecting block to move downward by the screw so that the adjusting belt can be fixed, so that the connection between the connecting belt and the tire can be further fixed by the adjusting device, which can effectively avoid the connection between the connecting belt and the tire from slipping when the connecting belt is connected to the tire for a long time.

[0008] Preferably, two auxiliary blocks are fixedly connected to the opening of the clamping plate, and the cross-section of the auxiliary blocks is arc-shaped.

[0012] Preferably, three support rods are fixedly connected to the arc surface of the screw rod, and one end of the three support rods away from the screw rod is fixedly connected to the same auxiliary rod.

[0013] The effect achieved by the above components is: when it is necessary to rotate the screw to drive the adjusting block to move, the auxiliary rod installed on the support rod can be used to rotate the screw. The auxiliary rod can increase the contact area between the hand and the screw, thereby improving the efficiency of the user's rotation of the screw.

[0014] Preferably, the arc surface of the auxiliary rod is provided with a plurality of anti-skid grooves, and the plurality of anti-skid grooves are evenly distributed on the auxiliary rod.

[0015] The effect achieved by the above components is: when the auxiliary rod is used to drive the screw rod to rotate, the anti-slip groove on the auxiliary rod can increase the friction between the user's hand and the auxiliary rod, thereby preventing the user from being unable to grip the auxiliary rod due to sweating hands when using the auxiliary rod.

[0017] The effect achieved by the above components is: by tying the connecting belt to the tire of the car, the anti-skid belt body on the connecting belt can be used to prevent the car from slipping during driving. However, when the road environment is relatively harsh, because the contact area between the anti-skid belt body on the connecting belt and the ground is small, a single anti-skid belt is difficult to provide a good anti-skid effect for the car. When the road environment is relatively harsh, a single anti-skid belt body will still slip. The connecting belts that need to be connected together are first connected to the car tires in turn, and then the connecting rod is rotated in the threaded groove. First, the threaded groove on the first connecting belt is connected to the connecting rod, and then the contact rod on the connecting rod is connected to the threaded groove on the second connecting belt. The two connecting belts can be connected through an auxiliary device, so that the contact area between the anti-skid belt body on the connecting belt and the ground can be increased by connecting the two connecting belts, thereby improving the anti-skid effect of the anti-skid belt body on the car tire.

[0019] The effect achieved by the above components is: when using a connecting rod to connect with a threaded groove, the guide block installed on the connecting rod can reduce the connection angle required for the connecting rod to connect with the threaded groove, making it easier for the connecting rod to connect with the threaded groove and improving the efficiency of the connection between the connecting rod and the threaded groove.

[0020] Preferably, a force rod is slidably penetrated through the inner wall of the contact rod, and protrusions are fixedly connected to both ends of the force rod.

[0021] The effect achieved by the above components is: when the contact rod needs to be rotated, the force rod installed on the contact rod can be used to rotate the contact rod. The force rod can increase the speed at which the user rotates the contact rod. The protrusions installed at both ends of the force rod can limit the sliding of the force rod in the contact rod, thereby preventing the force rod from slipping out of the contact rod.

[0022] Compared with the related art, the anti-skid belt for automobiles used at night provided by the utility model has the following beneficial effects:

[0023] The utility model provides an automobile anti-skid belt for use at night. By arranging an adjusting device, a connecting belt is easily loosened when being fixed to a tire for a long time. The adjusting device can improve the stability of the connection between the connecting belt and the tire, and can effectively prevent the connecting belt from loosening when being connected to the tire for a long time, thereby preventing the loose connecting belt from affecting the anti-skid effect of the anti-skid belt body on the tire.

[0024] By providing an auxiliary device, when the road conditions are complicated and a single anti-skid belt body can no longer provide the anti-skid effect for the vehicle tire, two identical connecting belts can be connected together through the auxiliary device to increase the contact area between the anti-skid belt body on the connecting belt and the ground, thereby improving the anti-skid effect of the anti-skid belt body on the vehicle tire.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0033] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0034] See also Figures 1 to 6 The embodiment of the utility model provides an anti-skid belt for automobiles used at night, comprising: a connecting belt 1, a non-skid belt body 4 is fixedly connected to the surface of the connecting belt 1, a reflective sticker 5 is provided on one side of the non-skid belt body 4, an adjusting device 2 is provided on one side of the connecting belt 1, and an auxiliary device 3 is provided on the upper surface of the connecting belt 1.

[0035] In the embodiments of the present invention, please refer to Figures 2 to 5The adjusting device 2 includes a fixing rod 201, which is fixedly connected to the connecting belt 1. One end of the fixing rod 201 is fixedly connected to a connecting plate 202. A connecting groove 203 is provided on one side of the connecting plate 202. An adjusting groove 204 is provided on the upper surface of the connecting plate 202. The side walls of the adjusting groove 204 are slidably connected to adjusting blocks 205. The sides of the two adjusting blocks 205 close to each other are fixedly connected to the same connecting block 206. The lower surface of the connecting block 206 is fixedly connected to a friction pad. A screw 207 is threaded through the inner wall of one of the adjusting blocks 205. The screw 207 is rotatably connected to the connecting plate 202. A connecting block 209 is fixedly connected to the lower surface of the connecting plate 202. An adjusting belt 210 is fixedly connected to one side of the connecting block 209. A snap-on plate 208 is fixedly connected to one side of the connecting belt 1, and an adjusting belt 210 is movably connected to the snap-on plate 208. By evenly bundling a number of connecting belts 1 on the tire of the vehicle, the anti-skid belt body 4 on the connecting belt 1 can provide an anti-skid effect for the tire. The reflective sticker 5 can serve as a warning for the anti-skid belt body 4 when the anti-skid belt body 4 is used at night. However, when the connecting belt 1 is connected to the tire for a long time, the connecting belt 1 and the tire are prone to loosening, which also causes the connecting belt 1 to shift on the tire surface as the tire moves. The anti-skid effect of the shifted anti-skid belt will be reduced. First, connect the connecting belt 1 to the vehicle tire, then connect the adjusting belt 210 on the connecting block 209 to the snap-on plate 208 through the tire, and then The adjusting belt 210 is stretched into the connecting groove 203 of the connecting plate 202, and the screw 207 is rotated. The adjusting block 205 and the connecting block 206 are driven downward by the screw 207 to fix the adjusting belt 210, so that the connection between the connecting belt 1 and the tire can be further fixed by the adjusting device 2, which can effectively prevent the connecting belt 1 from slipping between the connecting belt 1 and the tire when the connecting belt 1 is connected to the tire for a long time. Two auxiliary blocks 211 are fixedly connected to the opening of the clamping plate 208. The cross-section of the auxiliary block 211 is arc-shaped. When the adjusting belt 210 is connected to the clamping plate 208, the auxiliary block 211 installed on the clamping plate 208 can increase the speed of connecting the adjusting belt 210 to the clamping plate 208, which is convenient for the adjusting belt 210 to be connected to the clamping plate The connecting plate 208 is connected, and the inner wall of the other adjusting block 205 slides through the limiting rod 212, and one end of the limiting rod 212 is fixedly connected to the connecting plate 202. When the adjusting block 205 moves in the adjusting groove 204 driven by the screw 207, the limiting rod 212 can further limit the movement of the adjusting block 205, thereby improving the stability of the movement of the adjusting block 205 in the adjusting groove 204. The arc surface of the screw 207 is fixedly connected with three support rods 213, and one end of the three support rods 213 away from the screw 207 is fixedly connected with the same auxiliary rod 214. When the screw 207 needs to be rotated to drive the adjusting block 205 to move, the auxiliary rod 214 installed on the support rod 213 can be used to rotate the screw 207.The auxiliary rod 214 can increase the contact area between the hand and the screw 207, thereby improving the efficiency of the user's rotation of the screw 207. The arc surface of the auxiliary rod 214 is provided with a plurality of anti-skid grooves 215, and the plurality of anti-skid grooves 215 are evenly distributed on the auxiliary rod 214. When the auxiliary rod 214 is used to drive the screw 207 to rotate, the anti-skid grooves 215 on the auxiliary rod 214 can increase the friction between the user's hand and the auxiliary rod 214, thereby preventing the user from being unable to hold the auxiliary rod 214 due to sweating when using the auxiliary rod 214.

[0036] In the embodiments of the present invention, please refer to Figure 6 The auxiliary device 3 includes a contact block 31, a threaded groove 32 is provided on the side of the contact block 31, a connecting rod 33 is threadedly connected to the inner wall of the threaded groove 32, one end of the connecting rod 33 is fixedly connected to a connecting rod 34, the connecting rod 34 is made of rubber, and the end of the connecting rod 34 away from the connecting rod 33 is rotatably connected to a contact rod 35. The connecting belt 1 is tied to the tire of the car, and the anti-skid belt body 4 on the connecting belt 1 can be used to prevent the car from slipping during driving. However, when the road environment is relatively bad, because the anti-skid belt body 4 on the connecting belt 1 The contact area between the sliding belt body 4 and the ground is small, and a single anti-skid belt is difficult to provide a good anti-skid effect for the car. When the road environment is relatively bad, the single anti-skid belt body 4 will still slip. The connecting belts 1 that need to be connected together are first connected to the car tires in sequence, and then the connecting rod 33 is rotated in the thread groove 32. The thread groove 32 on the first connecting belt 1 is first connected to the connecting rod 33, and then the contact rod 35 on the connecting rod 34 is connected to the thread groove 32 on the second connecting belt 1. The two connecting belts 1 can be connected together through the auxiliary device 3. The two connecting belts 1 are connected, so that the contact area between the anti-skid belt body 4 on the connecting belt 1 and the ground can be increased by connecting the two connecting belts 1, so as to improve the anti-skid effect of the anti-skid belt body 4 on the automobile tire. The end of the connecting rod 33 away from the connecting rod 34 is fixedly connected with a guide block 36, and the guide block 36 is a titanium alloy block. When the connecting rod 33 is connected to the thread groove 32, the guide block 36 installed on the connecting rod 33 can reduce the connection angle required for the connection between the connecting rod 33 and the thread groove 32, so that the connecting rod 33 can be connected to the thread groove 32 more quickly. To improve the efficiency of the connection between the connecting rod 33 and the threaded groove 32, a force rod 37 is slidably penetrated through the inner wall of the contact rod 35, and both ends of the force rod 37 are fixedly connected with protrusions 38. When the contact rod 35 needs to be rotated, the force rod 37 installed on the contact rod 35 can be used to rotate the contact rod 35. The force rod 37 can increase the speed at which the user rotates the contact rod 35. The protrusions 38 installed at both ends of the force rod 37 can limit the sliding of the force rod 37 in the contact rod 35, thereby preventing the force rod 37 from slipping out of the contact rod 35.

[0037] The working principle of the automobile anti-skid belt used at night provided by the utility model is as follows: a plurality of connecting belts 1 are evenly tied to the tire of the automobile, and the anti-skid belt body 4 on the connecting belt 1 can provide an anti-skid effect for the tire, and the reflective sticker 5 can make the anti-skid belt body 4 play a warning role for the anti-skid belt body 4 when used at night. However, when the connecting belt 1 is connected to the tire for a long time, the connecting belt 1 and the tire are easily loosened, which also causes the connecting belt 1 to deviate on the tire surface with the movement of the tire, and the anti-skid effect of the deviated anti-skid belt is reduced. The result will be reduced, first connect the anti-skid belt to the vehicle tire, then connect the adjustment belt 210 on the connecting block 209 to the clamping plate 208 through the tire, and then stretch the adjustment belt 210 into the connecting groove 203 of the connecting plate 202, rotate the screw 207, and drive the adjustment block 205 and the connecting block 206 to move downward through the screw 207, so that the adjustment belt 210 can be fixed, so that the connection between the connecting belt 1 and the tire can be further fixed through the adjusting device 2, which can effectively prevent the connecting belt 1 from being connected to the tire for a long time. In the event of slippage between the tires, when the adjustment belt 210 is connected to the clamping plate 208, the auxiliary block 211 installed on the clamping plate 208 can increase the speed of connecting the adjustment belt 210 to the clamping plate 208, making it easier for the adjustment belt 210 to connect to the clamping plate 208. When the adjustment block 205 moves in the adjustment slot 204 driven by the screw 207, the limiting rod 212 can further limit the movement of the adjustment block 205, thereby improving the stability of the movement of the adjustment block 205 in the adjustment slot 204. The screw 207 needs to be rotated to drive the adjustment block 205 to move in the adjustment slot 204. When the adjustment block 205 moves, the auxiliary rod 214 installed on the support rod 213 can be used to rotate the screw rod 207. The auxiliary rod 214 can increase the contact area between the hand and the screw rod 207, thereby improving the efficiency of the user's rotation of the screw rod 207. When the auxiliary rod 214 is used to drive the screw rod 207 to rotate, the anti-slip groove 215 on the auxiliary rod 214 can increase the friction between the user's hand and the auxiliary rod 214, thereby avoiding the situation where the user's hands sweat and cannot grip the auxiliary rod 214 when using the auxiliary rod 214.

[0038] By tying the connecting belt 1 to the tire of the car, the anti-skid belt body 4 on the connecting belt 1 can be used to prevent the car from slipping during driving. However, when the road environment is relatively bad, because the contact area between the anti-skid belt body 4 on the connecting belt 1 and the ground is small, a single anti-skid belt is difficult to provide a good anti-skid effect for the car. When the road environment is relatively bad, a single anti-skid belt body 4 will still slip. The connecting belts 1 that need to be connected together are first connected to the car tires in turn, and then the connecting rod 33 is rotated in the threaded groove 32. The threaded groove 32 on the first connecting belt 1 is first connected to the connecting rod 33, and then the contact rod 35 on the connecting rod 34 is connected to the threaded groove 32 on the second connecting belt 1. The two connecting belts 1 can be connected through the auxiliary device 3, so that the two connecting belts 1 can be connected. The connection is performed to increase the contact area between the anti-skid belt body 4 on the connecting belt 1 and the ground, thereby improving the anti-skid effect of the anti-skid belt body 4 on the automobile tire. When the connecting rod 33 is used to connect with the thread groove 32, the guide block 36 installed on the connecting rod 33 can reduce the connection angle required for the connection between the connecting rod 33 and the thread groove 32, so that the connecting rod 33 is connected to the thread groove 32 more quickly, thereby improving the efficiency of the connection between the connecting rod 33 and the thread groove 32. When it is necessary to rotate the contact rod 35, the force rod 37 installed on the contact rod 35 can be used to rotate the contact rod 35. The force rod 37 can increase the speed at which the user rotates the contact rod 35. The protrusions 38 installed at both ends of the force rod 37 can limit the sliding of the force rod 37 in the contact rod 35, thereby preventing the force rod 37 from slipping out of the contact rod 35.
