Description

Technical Field

[0001] This utility model belongs to the field of road barrier technology, and in particular relates to a tire deflation device. Background Technology

[0002] Tire puncture devices, also known as spike barriers or barbed tire barriers, are a type of tire-puncturing roadblock. The spikes on a spike barrier are quite sharp; once a vehicle runs over it, the tire will be punctured within 0.5 seconds, releasing the air through the vent and preventing the vehicle from moving. Therefore, tire puncture devices are an essential anti-terrorism roadblock in some high-security locations.

[0003] Most existing tire deflation devices have an integrated pin and pin seat structure. If the pin punctures the tire, the deflation device may be pulled away by the wheel, causing vehicle damage. To address this problem, sometimes the tire deflation device is fixed to the road surface or its weight is increased. These solutions are inconvenient, time-consuming, and labor-intensive, requiring a better solution. Utility Model Content

[0004] In order to solve the technical problem of the inconvenience of using conventional tire deflators in the background art, the purpose of this utility model is to provide a tire deflator that can solve the above problems.

[0005] The technical solution to achieve the purpose of this utility model is: a tire puncture device, including a pin and a pin seat, wherein the pin is movably mounted on the pin seat and is used to separate from the pin seat after the pin punctures the tire.

[0006] This solution provides a tire deflation device with a detachable pin mounted on a nail holder. When a car tire runs over the device, the pin punctures the tire, causing a leak and thus creating a roadblock. Once the pin is in place, it separates from the nail holder; the pin moves with the tire while the nail holder remains in its original position on the ground. Compared to traditional nail holders that may move with the tire, this device does not damage the vehicle, does not add weight to the nail holder, and does not require fixing the nail holder to the road surface. It is ready to use immediately upon unfolding, making it convenient and quick.

[0007] Furthermore, the pin holder is provided with a post, and the tail of the pin has a slot corresponding to the post. The pin is installed on the pin holder through the cooperation of the post and the slot. This solution adopts a plug-in installation method using a slot and post, which is flexible in installation and facilitates separation. An interference fit can be used during installation. Alternatively, the post may have a connecting lug at its bottom, and the slot is inserted into the connecting lug.

[0008] Furthermore, the pin has a hollow structure, which on the one hand makes it easier for the pin to puncture the car tire and cause the tire to leak air, and on the other hand reduces the weight of the pin, making it easier for the pin to move with the vehicle after it punctures the tire. Of course, it also reduces the use of consumables and lowers costs.

[0009] Furthermore, it also includes a nail head, wherein the head of the pin has a pointed tip, and the head of the pin is inserted into the nail head. Because the head of the pin has a pointed tip, a nail head is added to prevent accidental injury to workers, and the length of the nail head is shorter than the length of the pin, making it easy to remove the nail head during use, reducing material consumption, and lowering costs.

[0010] Furthermore, the nail head is made of latex, meaning that the material of the nail head is easily pierced by the sharp corner of the pin. This eliminates the need to remove the nail head separately during use, increasing the efficiency and convenience of the tire puncturer.

[0011] Furthermore, the nail holder is a telescopic base plate, on which multiple pins are evenly arranged. The telescopic design of the nail holder facilitates transportation of the storage box and allows for the placement of multiple pins, enhancing the tire-breaking function and effectiveness of the tire puncture device.

[0012] Furthermore, the telescopic base plate is made of nylon multifiber, which is lightweight, making it easy to store and use the tire deflation device; it also has high rigidity, can withstand a large weight, and will not be damaged even if a car runs over it multiple times.

[0013] Furthermore, pull ropes are installed on both sides of the telescopic base plate to facilitate the extension and retraction of the telescopic base plate during use. The extension or retraction can be completed by manually gripping the pull ropes.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects:

[0015] (1) This solution provides a tire puncture device in which the pin and the pin seat can be separated. After the pin is inserted into the car tire, it will separate from the pin seat. This can achieve the function of puncturing the car tire and will not cause the pin seat to damage the vehicle. It also does not require increasing the weight of the pin seat or fixing it.

[0016] (2) The pin and the pin seat are installed by a slot and a plug-in type, which is simple and flexible to install and facilitates separation of the two.

[0017] (3) The pin is designed as a hollow structure, which makes it easy to deflate the tire after it is inserted into the tire. The hollow structure formed inside is also a slot, which can be directly inserted into the post for fixed installation.

[0018] (4) Add nail heads to the sharp corners of the pins to prevent accidental injury to operators. Furthermore, the nail heads are designed to be made of latex, so they do not need to be removed during use. When the tire presses on the pin, the pin will break through the nail head and puncture the tire, making it more convenient.

[0019] (5) The nail base is designed as a telescopic base plate for easy storage. Furthermore, nylon multifiber is selected, which is lightweight and has high rigidity. Attached Figure Description

[0029] Preferably, the pin 1 has a hollow structure, which facilitates the pin 1 to puncture the car tire and cause the tire to leak air, and also reduces the weight of the pin 1, making it easier for the pin 1 to move with the vehicle after it punctures the tire. Of course, it also reduces the use of consumables and lowers costs.

[0030] Preferably, the device also includes a nail head 6, wherein the head of the pin 1 has a pointed corner 7, and the head of the pin 1 is inserted into the nail head 6. Because the head of the pin 1 has a pointed corner 7, a nail head 6 is added to prevent accidental injury to workers, allowing it to be fitted onto the pin 1. The length of the nail head 6 is shorter than the length of the pin 1, making it easy to remove during use and reducing material consumption and costs. The nail head 6 is made of latex, meaning it is easily punctured by the pointed corner 7 of the pin 1. This eliminates the need to remove the nail head 6 separately during use, increasing the efficiency and convenience of the tire puncturer.

[0031] Preferably, the nail holder 2 is a telescopic base plate 8, on which multiple pins 1 are evenly arranged. The telescopic design of the nail holder 2 facilitates transport and storage, and allows for the placement of multiple pins 1, enhancing the tire-puncturing function and effectiveness of the tire puncture device. The telescopic base plate 8 is made of nylon multifiber, which is lightweight, facilitating the storage and use of the tire puncture device; it also possesses high rigidity, capable of withstanding significant weight, and will not be damaged even after repeated runs by vehicles. Pull ropes 9 are installed on both sides of the telescopic base plate 8, facilitating its extension and retraction during use; simply gripping the pull ropes 9 will retract or extend the plate manually.

[0032] Working principle: When in use, the car tire runs over the tire deflation device, the pin 1 separates from the pin seat 2 and punctures the car tire, and air leaks out from the hollow interior of the pin 1, causing the car tire to leak air and achieving the purpose of a roadblock.
