Description

Technical Field

[0001] The utility model relates to the technical field of tire breaker, in particular to a portable tire breaker. Background Art

[0002] In road traffic management, when some lawbreakers or traffic offenders drive cars to escape, it is difficult to intercept them while ensuring the safety of law enforcement officers because the cars have a high speed and a large impact force, especially on urban roads with a large number of people and traffic. If the interceptors are not careful, serious traffic and safety accidents will occur. In addition, for some drivers with weak safety and legal awareness, they often drive after drinking. When such drivers are investigated and punished, they will take extreme actions such as speeding up and rushing through checkpoints to avoid punishment. If such vehicles cannot be stopped in time, they will also cause traffic and safety accidents.

[0003] To this end, someone has designed a tire breaker, which aims to deflate the tires of illegal vehicles and make the vehicles unable to move, without causing damage to the vehicles or injuries to people. However, the steel nails of the tire breaker currently used are generally exposed, making it inconvenient to store them. At the same time, the exposed steel nails are not concealed enough, which may cause people to discover them in advance and take a detour.

It can be conveniently placed on the ground in front of the wheel. When the wheel rolls forward to the tire breaker mechanism, the steel nail punctures the tire while the shield is broken, and under the strong friction of the wheel rubber and the rolling action of the wheel itself, the steel nail is immediately pulled out of the base and stuck on the wheel, and the base remains unchanged, so that the air in the tire leaks out through the vertical through hole on the steel nail, and finally the vehicle cannot be driven and is forced to stop, effectively preventing the driver from driving away, and at the same time, the damaged tire breaker mechanism can be conveniently replaced in time, but the above patent document still has the following defects during use:

[0005] The mechanism of the above patent document will destroy a batch of shields each time it is used during use, and shields need to be prepared at any time to shield the steel nails during transportation, which is inconvenient to carry. Utility Model Content

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1 and Figure 2 As shown, a portable tire breaker includes a shell 1, a groove is formed at the front end of the shell 1, a strong plastic plate 7 is fixedly connected to the inside of the groove, a support plate 2 is fixedly connected to the bottom wall of the inner surface of the shell 1, a limit assembly 5 is provided on the upper part of the support plate 2, an extrusion assembly 6 is slidably connected to the front part of the bottom wall of the inner surface of the shell 1, a plurality of trigger assemblies 3 located in front of the extrusion assembly 6 are fixedly connected to the bottom wall of the inner surface of the shell 1, and a threaded rod 4 is rotatably connected to the lower part of the front side wall of the inner surface of the shell 1.

[0028] In the specific implementation process of this scheme, the device is first placed on the road. At this time, the steel nails 21 are placed inside the shell 1, and the support plate 2 is limited by the limiting component 5. When the intercepted vehicle passes over the shell 1 and the wheel squeezes the strong plastic plate 7, the several trigger components 3 are squeezed and will immediately push the squeezing component 6 to push the lower part of the strong plastic plate 7 to release the limit on the support plate 2. At this time, several steel nails 21 immediately rush out from the through hole 11 on the same side to puncture the tire. In this process, the vehicle is used to trigger several steel nails 21, which saves driving force. After use, the support plate 2 is re-limited by the threaded rod 4, and the steel nails 21 are stored in the shell 1 for easy transportation.

[0029] Specifically, in order to facilitate carrying and transportation and avoid stabbing workers, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The upper end of the housing 1 is provided with a plurality of through holes 11, and the lower front end of the housing 1 is provided with a through hole 2 12 corresponding to the position of the threaded rod 4;

[0030] For further information, see Figure 2 The upper end of the support plate 2 is fixedly connected with a plurality of steel nails 21 corresponding to the positions of the through holes 11 on the same side, and the end of the support plate 2 and the housing 1 close to each other is fixedly connected with a plurality of springs 22;

[0031] For further information, see Figure 4 The limiting assembly 5 includes a limiting plate 51, a slide bar 53 is fixedly connected to the lower rear end of the limiting plate 51, a sleeve 52 is slidably connected to the outer surface of the slide bar 53, an arc spring 54 is fixedly connected to the bottom wall of the inner surface of the sleeve 52 and the lower end of the slide bar 53, and a rotating shaft 55 is rotatably connected to the lower rear end of the limiting plate 51;

[0032] For further information, see Figure 4 , the sleeve 52 is fixedly connected to the bottom wall of the inner surface of the outer shell 1, and the rotating shaft 55 is fixedly connected to the outer shell 1 through a fixing plate;

[0033] The upward elastic force applied by the plurality of springs 22 to the support plate 2 is much greater than the pressure of the automobile tire on the steel nails 21. When the automobile passes over the plurality of steel nails 21, the tire can be punctured smoothly.

[0034] The tension provided by the middle arc spring 54 can help the limiting plate 51 and the supporting plate 2 to be in close contact.

[0035] It can be seen that when no vehicle presses over the strong plastic plate 7, the limiting plate 51 is placed on the upper end of the support plate 2, so that the support plate 2 squeezes the plurality of springs 22, and the plurality of steel nails 21 are placed inside the housing 1. At this time, the arc spring 54 is used to provide a pulling force on the slide bar 53, so that the limiting plate 51 is tightly attached to the upper end of the support plate 2, and cooperates with Figure 2 The plurality of springs 22 are located at the front of the lower end of the support plate 2, so that the support plate 2 remains horizontal when pressed by the limiting plate 51. When the limiting plate 51 releases the limit on the support plate 2, the plurality of steel nails 21 can smoothly pass through the through hole 11 on the same side to puncture the tire.

[0036] Specifically, in order to achieve self-opening, puncture the tire, and save the cost of puncture, refer to Figure 5 and Figure 6 The outer surface of the threaded rod 4 is threadedly connected with a connecting plate, the connecting plate is fixedly connected to the housing 1, and a card slot is opened at the front end of the threaded rod 4;

[0037] For further information, see Figure 6 The extrusion assembly 6 includes a push plate 61, a front end of which is fixedly connected to a plurality of Z-shaped rods 62, and the plurality of Z-shaped rods 62 are fixedly connected to the housing 1 through a connecting block;

[0038] For further information, see Figure 6 The trigger assembly 3 includes a vertical rod 31, the lower end of the extrusion block 32 is a beveled surface, the left and right ends of the extrusion block 32 are fixedly connected to the housing 1 with a spring 2 33, and a plurality of vertical rods 31 are fixedly connected to the upper annular array on the outer surface of the vertical rod 31;

[0039] It can be seen that when the vehicle presses over the strong plastic plate 7, the strong plastic plate 7 can smoothly squeeze the vertical rods 31 with its own elastic force. At this time, the vertical rods 31 move downward, and cooperate with the chamfered surface at the lower end of the squeezing block 32. Then, as the vertical rods 31 descend, the Z-shaped rods 62 are gradually squeezed to slide backward. At this time, the push plate 61 can be squeezed to apply pressure to the lower part of the limit plate 51. At this time, the upper part of the limit plate 51 will rotate around the rotating shaft 55 and move away from the support plate 2, so that the squeeze limit of the support plate 2 can be released. At this time, the support plate 2 is under the elastic force of the plurality of springs 22, so that the plurality of steel nails 21 can be smoothly ejected from the through hole 11 to puncture the tire.

[0040] During the rotation of the limit plate 51, the slide bar 53 will pull the arc spring 54 to slide inside the casing 52, stretching the arc spring 54. When the support plate 2 moves upward, the limit plate 51 is reset to the bottom of the support plate 2 under the action of the arc spring 54. When the tire is away from the strong plastic plate 7, the plurality of vertical rods 31 are no longer squeezed. Under the action of the plurality of springs 33, the squeezing block 32 will be reset to release the squeezing of the Z-shaped rod 62. At this time, when the limit plate 51 is reset, it will rotate in the opposite direction around the rotating shaft 55, and the push plate 61 can be squeezed to drive the plurality of Z-shaped rods 62 to reset.

[0041] After use, another insertion rod can be taken and inserted into the groove in the front part of the threaded rod 4 through the through hole 12, and the threaded rod 4 can be driven to rotate mechanically, so that the threaded rod 4 moves backward under the limit of the connecting plate, squeezing the push plate 61 so that it squeezes the limit plate 51 again, so that the limit plate 51 is away from the support plate 2. At this time, the pressure plate is used to press down a number of steel nails 21, so that the support plate 2 is placed under the horizontal part of the limit plate 51, and the threaded rod 4 can be rotated in the opposite direction again to make the threaded rod 4 gradually move away from the push plate 61, and then the limit plate 51 is reset to limit the support plate 2 again, completing the storage of a number of steel nails 21, so as to facilitate transportation and next use.
