Abstract
Description
Technical Field
[0001] This utility model relates to the field of road barrier technology, and in particular to a vehicle blocking device for vehicles attempting to break through barriers. Background Technology
[0002] Roadblocks, also known as ejector-type remote-controlled vehicle interceptors or tire spikes, are used in traffic safety to quickly and safely intercept vehicles. Border guards or police officers on duty inevitably encounter vehicles attempting to break through checkpoints and need to use roadblocks to stop them.
[0003] Patent specification CN204401506U discloses a portable throwable tire spike, comprising a steel wire rope, one end of which is wound into a loop to form a throwing wristband. Multiple fixed bodies are spaced apart on the steel wire rope and fixedly connected to it. Each fixed body has a connecting ring, and a deflated tire spike is fixedly connected to the connecting ring. The main weight of the tire spike provided by this invention is in the steel wire rope, the fixed blocks, and the deflated tire spikes, with no other unnecessary weight, making it suitable for use on duty. In case of an emergency, security personnel only need to hold the throwing wristband and throw the other end. The deflated tire spikes can quickly arrange themselves on the road to form a roadblock, obstructing suspicious vehicles. Security personnel can then pull the deflated tire spikes back using the throwing wristband to remove the roadblock, without affecting subsequent pursuit or measurement.
[0004] However, during the implementation of the relevant technology, the following problems were found in the portable throwable tire spikes designed above: since the tire spikes are retrieved by security personnel using a throwing wristband to pull back the deflated spikes, if the deflated spikes become embedded in the tires of the suspect vehicle during the interception process, but the suspect vehicle continues to move forward, it may drag the security personnel in the opposite direction via the steel cable, resulting in injury. In view of this, a vehicle blocking device is now provided to overcome the above defects. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a vehicle obstacle.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a vehicle obstacle blocker, comprising a steel column, a support rod provided in the middle of the steel column, and a chassis fixed at the end of the support rod away from the steel column. The support rod is used to determine the position of the chassis and support the chassis. A hollow retractable rod is provided above the chassis, and an electromagnet is installed inside the lower part of the retractable rod. Several sets of retractable rods are provided, and the several sets of retractable rods are sequentially nested. The outer diameter of the retractable rods increases sequentially from top to bottom, so that the upper set of retractable rods can be stored in the lower set of retractable rods, thereby realizing the retraction of the vehicle obstacle blocker. A rotating head is provided at the uppermost end of the retractable rod, and the surface of the rotating head is provided with a H-shaped groove. A retractable rod assembly is provided between the rotating head and the steel column. The retractable rod assembly can rotate on one side of the rotating head through the H-shaped groove, thereby rotating and retracting inward as the retractable rod retracts, so that the vehicle obstacle blocker is in a standby state.
[0007] The retractable rod assembly includes connecting rods and compression springs installed between the connecting rods. A connecting ring is provided at the end of the connecting rod away from the compression spring. When the compression spring is compressed inward, the connecting rods at both ends can retract inward and move closer together.
[0008] As a further description of the above technical solution: the three sets of steel columns are welded end to end in pairs, and the three sets of steel columns form an equilateral triangle structure, with the steel columns serving as the bottom support structure.
[0009] As a further description of the above technical solution: the steel column and the two sets of retractable rod assemblies form an equilateral triangle structure, and the three sets of steel columns and the three sets of retractable rod assemblies form a regular tetrahedral structure. The regular tetrahedral structure of the obstacle blocker remains a stable regular tetrahedral structure even when flipped, which can effectively block vehicles that attempt to break through the barrier.
[0010] As a further description of the above technical solution: a buckle is provided at the connection between the steel column and the connecting ring, and the buckle is located above the connection between the two sets of steel columns. The buckle is used to connect with the connecting ring.
[0011] As a further description of the above technical solution: the retractable rod assembly rotates on the steel column via a connecting ring and a buckle, and the retractable rod assembly rotates on the rotating head via a connecting ring and a D-shaped groove, and the angle between the retractable rod assembly and the rotating head can be changed via the connecting ring and the D-shaped groove.
[0012] As a further description of the above technical solution: a power supply battery is installed inside the chassis, and a microprocessor is provided on one side of the power supply battery. A wireless transceiver is installed on one side of the microprocessor. The wireless transceiver can receive wireless signals, thereby sending signals to the microprocessor through the wireless transceiver to achieve remote control.
[0013] As a further description of the above technical solution: the inner retraction rod is perpendicular to the chassis, and the vertical center line of the chassis coincides with the vertical center line of the obstacle blocking device, with the chassis located at the bottom center of the obstacle blocking device.
[0014] This utility model has the following beneficial effects:
[0015] The vehicle blocking device designed in this utility model consists of a regular tetrahedral structure formed by steel columns and retractable rods, which is consistent with the shape of an anti-tank cone. Even if the vehicle flips over, it can block the vehicle, allowing staff to stay away from the suspect vehicle and avoid injury from a vehicle collision.
[0016] This utility model designs a vehicle obstacle barrier that, by incorporating an inward-retracting rod and a retractable rod assembly, can retract inward when not in use. This lowers the height of the entire obstacle barrier by causing the top to fold down, allowing vehicles to pass normally. Simultaneously, it can send signals to a microprocessor via a wireless transceiver to remotely control the electromagnet. When the electromagnet is energized, the obstacle barrier is compressed and in standby mode; otherwise, it is in working mode, making it suitable for various applications. Attached Figure Description

[0023] Reference Figure 1-4The present invention provides a vehicle obstacle blocker, comprising a steel column 5, a support rod 4 in the middle of the steel column 5, and a chassis 3 fixed at the end of the support rod 4 away from the steel column 5. The support rod 4 is used to determine the position of the chassis 3 and support the chassis 3. A hollow retractable rod 7 is provided above the chassis 3, and an electromagnet 8 is installed in the lower part of the interior of the retractable rod 7. Several sets of retractable rods 7 are provided, and the sets of retractable rods 7 are sequentially nested. The outer diameter of the retractable rods 7 increases sequentially from top to bottom. The upper set of retractable rods 7 can be stored in the lower set of retractable rods 7, thereby realizing the retraction of the vehicle obstacle blocker. A rotating head 2 is provided at the uppermost end of the retractable rod 7, and a H-shaped groove 6 is opened on the surface of the rotating head 2. A retractable rod assembly 1 is provided between the rotating head 2 and the steel column 5. The retractable rod assembly 1 can rotate on one side of the rotating head 2 through the H-shaped groove 6, thereby rotating and retracting inward as the retractable rod 7 retracts, so that the vehicle obstacle blocker is in a standby state.
[0024] The retractable rod assembly 1 includes a connecting rod 102 and a compression spring 101 installed between the connecting rods 102. A connecting ring 103 is provided at the end of the connecting rod 102 away from the compression spring 101. When the compression spring 101 is compressed inward, the connecting rods 102 at both ends can retract inward and move closer together.
[0025] As a further implementation of the above technical solution: the three sets of steel columns 5 are welded end to end in pairs, and the three sets of steel columns 5 form an equilateral triangle structure, with the steel columns 5 serving as the bottom support structure.
[0026] As a further implementation of the above technical solution: the steel column 5 and the two sets of retractable rod assemblies 1 form an equilateral triangle structure, and the three sets of steel columns 5 and the three sets of retractable rod assemblies 1 form a regular tetrahedral structure. The regular tetrahedral structure of the obstacle blocker remains a stable regular tetrahedral structure even when flipped, which can effectively block vehicles that attempt to break through the barrier.
[0027] As a further implementation of the above technical solution: a buckle is provided at the connection between the steel column 5 and the connecting ring 103, and the buckle is located above the connection between the two sets of steel columns 5. The buckle is used to connect with the connecting ring 103.
[0028] As a further implementation of the above technical solution: the retractable rod assembly 1 rotates on the steel column 5 via the connecting ring 103 and the ring buckle, and the retractable rod assembly 1 rotates on the rotating head 2 via the connecting ring 103 and the H-shaped groove 6. The angle between the retractable rod assembly 1 and the rotating head 2 can be changed by the connecting ring 103 and the H-shaped groove 6.
[0029] As a further implementation of the above technical solution: a power supply battery 11 is installed inside the chassis 3, and a microprocessor 10 is provided on one side of the power supply battery 11. A wireless transceiver 9 is installed on one side of the microprocessor 10. The wireless transceiver 9 can receive wireless signals, thereby sending signals to the microprocessor 10 through the wireless transceiver 9 to achieve remote control.
[0030] As a further implementation of the above technical solution: the inner rod 7 is perpendicular to the chassis 3, and the vertical center line of the chassis 3 coincides with the vertical center line of the obstacle blocking device, and the chassis 3 is located at the bottom center of the obstacle blocking device.
[0031] In practice, the obstacle course vehicle blocker has two states: a standby state and a working state. In the standby state, the compression spring 101 contracts inward, causing the connecting rods 102 to come closer together. Then, the rotating head 2 presses down and gradually presses against the chassis 3. The inner retracting rods 7 between the rotating head 2 and the chassis 3 retract sequentially into the inner retracting rods 7 of the next set. The electromagnets 8 inside the inner retracting rods 7 attract each other magnetically, locking the obstacle course vehicle blocker. At this time, the obstacle course vehicle blocker is compressed into a plane. After being placed on the road, vehicles can pass through it normally.
[0032] When in normal duty, the product is activated and set up. The compression spring 101 unfolds outward, pushing the rotating head 2 upward. The vehicle barrier is a tetrahedral structure, making it impossible for any vehicle to pass over this product.
[0033] It can also be set up on a pre-predicted road. Normal vehicles can pass through normally. When a suspicious vehicle appears, the remote control is used to send a command to the wireless transceiver 9. When the wireless transceiver 9 receives the signal, it transmits the signal to the microprocessor 10. The microprocessor 10 controls the electromagnet 8 to be de-energized, and uses the elastic force of the compression spring 101 to put the obstacle to work.
[0034] When blocking a suspect vehicle while it is in motion, multiple obstacle blocks can be thrown in front of and behind the suspect vehicle to quickly stop it. The power supply battery 11 is used to power the entire obstacle block system.
[0035] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
