Description

Technical Field

[0001] The present invention relates to the technical field of police equipment, and in particular to a cable fixing component for a vehicle arrester and a vehicle arrester. Background Art

[0002] In a conventional scenario, when a criminal drives away in a vehicle and the police also drive to arrest, it is difficult to directly stop the criminal vehicle. There is often a long stalemate, resulting in the inability to quickly arrest the criminal. During the process of driving to arrest, the longer the arrest time, the greater the harm to the personal safety of the masses caused by the criminal vehicle.

[0003] Abroad, an automobile arrester called Grappler has been invented. It includes deployable forks and a box for accommodating cables. The cables are pasted on the inner side of the forks. During the arrest operation, the forks are flipped and deployed towards the ground. The cables form a mesh structure within the forks. The forks are sent to the outside of the rear wheels of the vehicle to be stopped. The cables come into contact with the wheels. At this time, the cables are wound around the wheels, making the wound wheels unable to rotate. At the same time, the cables tie the front and rear vehicles together, and the arrested vehicle cannot escape, thus assisting the police officers to quickly arrest and avoiding a long stalemate with the criminal vehicle.

[0004] "A vehicle stopping device" with the publication number CN115233591A discloses an automobile arrester similar to Grappler. Specifically (see paragraph 0037 of the specification), it discloses fixing the fixed end of the pulling rope to the fixed block on the pulling rope placement groove. Although it mentions detachable connection, it can be seen from the drawings that no specific detachable structure is provided.

[0005] Using the above-mentioned Grappler arrester can quickly arrest criminal vehicles. However, when the criminal gets out of the vehicle and escapes, since the cables tie the two vehicles together, the police officers also cannot drive to chase. They can only choose to cut the cables and then drive to chase, or directly run after. If cutting the cables to chase, the arrest cost increases, and it is also difficult to cut the cables. It is difficult to cut them in a short time. If directly running after, the arrest difficulty increases. In the above-mentioned "a vehicle stopping device", it is mentioned that the pulling rope is detachable. However, although using fixing methods such as bolts can disassemble the pulling rope, it is obvious that the pulling rope cannot be quickly disassembled, which still has a great impact on the arrest operation. Summary of the Invention

[0006] In view of this, the present invention provides a cable fixing component for a vehicle arrester and a vehicle arrester, which can quickly remove the cables from the vehicle arrester when the criminal vehicle is stopped and the criminal abandons the vehicle and runs away, so as to drive again to chase and reduce the arrest difficulty.

[0039] The cable fixing component of the vehicle arrester and the vehicle arrester of the present invention have the following

[0040] Advantages:

[0041] (1) A connecting belt is arranged on the fixing component, and the connecting belt is fixed on the fixing seat through a locking piece. By changing the position of the locking piece, the connecting belt can be detached from the fixing seat or installed on the fixing seat. Thus, when arresting a vehicle, the connecting belt and the rope body can be quickly detached, avoiding the situation where criminals abandon the vehicle and flee and the police officers need to get out of the vehicle to chase, thereby improving the arrest efficiency of criminals;

[0042] (2) By arranging two positioning grooves with different heights on the fixing seat and placing the handle of the locking piece in one of the positioning grooves, the connecting belt can be fixed or detached from the connecting belt. The user can pull the handle to make it enter different positioning grooves, thereby changing the connection state between the pin and the connecting belt, realizing rapid switching, and having strong stability and mechanical anti-deformation ability after switching to fix the connecting belt;

[0043] (3) By arranging the fixing component on the vehicle arrester, the rope body can be quickly detached after the criminal vehicle is arrested, enabling the arresting vehicle to carry the vehicle arrester and leave without cutting or detaching the rope body from the tire, thereby assisting the police officers to quickly stop the vehicle and avoiding a long-term stalemate with the criminal vehicle;

[0044] (4) The arranged mesh plate can shield the rope body, avoiding problems such as entanglement caused by the rope body touching external objects, and at the same time improving the overall aesthetics of the vehicle arrester. The mesh holes on the mesh plate can allow air to flow, avoiding blocking the intake of the vehicle air conditioner;

[0045] (5) By arranging a buffer member, when the first-stage deployment rack and the second-stage deployment rack are folded, the second-stage deployment rack will contact the elastic movable end of the buffer member and slightly squeeze the elastic movable end. Supported by the elastic movable end, the second-stage deployment rack cannot directly contact the mounting rack, avoiding mechanical collision caused by direct contact, thereby effectively protecting the vehicle arrester.

[0055] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0056] As Figure 1-4 shown, the cable fixing assembly of the vehicle arrester of the present invention includes two fixing seats 1, a connecting band 2, two locking members 3 and a rope body 4.

[0057] The two fixing seats 1 are the main fixing components of the rope body 4. When arresting a criminal vehicle, they will bear the tension of the rope body 4. Therefore, the fixing seats 1 need to have strong anti-deformation ability, preferably stainless steel parts. A plurality of threaded holes are provided on the fixing seats 1. The two fixing seats 1 can be directly fixed on the vehicle arrester by bolts and stably connected to the vehicle arrester. On the vehicle arrester, the two fixing seats 1 are mirror images of each other. Slots 11 are provided on both of the two fixing seats 1, and the slots 11 provided on the two fixing seats 1 can accommodate the ends of the connecting band 2.

[0058] The connecting belt 2 is integrally strip-shaped, and its two ends respectively extend into the two slots 11 and are fixed to the two fixing seats 1. Locking openings are also provided at the two ends of the connecting belt 2. The connecting belt 2 is the main transmission component of the pulling force of the rope body 4 and bears a relatively large pulling force. Therefore, the connecting belt 2 needs to be made of the same material as the lifting belt. Specifically, polyester, polypropylene, nylon or ultra-high molecular weight polyethylene can be selected, all of which have the advantages of softness and large load capacity.

[0059] The two locking members 3 are respectively arranged on the two fixing seats 1 and can move relative to the fixing seats 1. During the movement of the locking members 3, they can be inserted into the slots 11 or leave the slots 11. When the end of the connecting belt 2 is located in the slot 11 and the locking member 3 passes through the slot 11, the locking member 3 simultaneously passes through one end of the connecting belt 2 to fix the end of the connecting belt 2 to the fixing seat 1. When the locking member 3 does not pass through the slot 11, the locking member 3 does not contact the connecting belt 2, and the end of the connecting belt 2 can be withdrawn from the slot 11 or the connecting belt 2 can be placed into the slot 11. It should be noted that when the locking member 3 fixes the fixing seat 1 and the connecting belt 2, it only means that the connecting belt 2 cannot be separated from the fixing seat 1.

[0060] The material of the rope body 4 is the same as that of the connecting belt 2. One end of the rope body 4 is fixed to the connecting belt 2, and the fixing method can be stitching. After the rope body 4 is connected to the two fixing seats 1 through the connecting belt 2, it can be stacked on the connecting belt 2 for standby, which is convenient for the rope body 4 to be unfolded during subsequent use. The length of the rope body 4 can be set at about eight meters, so as to leave a certain braking space for the capture vehicle during the capture operation and avoid too large a distance between the two vehicles.

[0061] As a preferred embodiment, the connecting belt 2 includes a cloth belt 21 and two metal parts 22. The two metal parts 22 respectively extend into the two slots 11. The cloth belt 21 is fixed to the end of the rope body 4 and is respectively fixed to the two metal parts 22 at both ends. A through hole for the cloth belt 21 to pass through is provided on the metal part 22. The end of the cloth belt 21 is inserted into the through hole and forms a loop to fix the metal part 22 at the end of the cloth belt 21. During use, the metal part 22 directly contacts the locking member 3, avoiding the locking member 3 directly passing through the cloth belt 21, improving the tensile resistance of the cloth belt 21 when being pulled, and at the same time, the setting of the metal part 22 makes it easier to be placed into the slot 11.

[0062] To facilitate the movement of the locking member 3 relative to the fixed seat 1, the locking member 3 includes a pin 31 and a handle 32. The pin 31 is movably arranged in the fixed seat 1 and passes through or leaves the connecting belt 2 by sliding up and down. The handle 32 is fixed on the pin 31 and extends to the outside of the fixed seat 1. Specifically, the pin 31 is perpendicular to the end of the connecting belt 2. By pushing the handle 32, the pin 31 can be driven to move, so that the pin 31 passes through the connecting belt 2 or leaves the connecting belt 2. One end of the handle 32 away from the pin 31, that is, the end of the handle 32 located outside the fixed seat 1, is spherical, which is convenient for the user to hold and avoids the handle 32 slipping off during operation.

[0063] In this embodiment, in order to limit the position of the locking member 3 after being fixedly connected to the connecting belt 2 or leaving the connecting belt 2, two positioning grooves 12 are opened on the fixed seat 1. Both of the two positioning grooves 12 communicate with the slot 11. The handle 32 extends into one of the positioning grooves 12. The two positioning grooves 12 are at different horizontal heights. When the handle 32 is placed in the positioning groove 12 with a higher horizontal position, the pin 31 penetrates the connecting belt 2. When the handle 32 is placed in the positioning groove 12 with a lower horizontal position, the pin 31 does not contact the connecting belt 2.

[0064] In this embodiment, the two positioning grooves 12 are staggered from each other. The pin 31 is perpendicular to the ground. Under the action of gravity, the pin 31 cannot move upward by itself, and the handle 32 can fall into the positioning groove 12. After lifting the handle 32 into the slot 11, it can be switched between the two positioning grooves 12, so as to install or remove the connecting belt 2.

[0065] That is to say, when it is necessary to remove the rope body 4 so that it is not connected to the vehicle on which the vehicle arrester is installed, the handle 32 can be pulled to switch the positioning groove 12 where it is located, and the rope body 4 can be removed from the vehicle arrester, thus completing the rapid removal operation. On the contrary, installation can be carried out.

[0066] As Figure 1-8 shown, the vehicle arrester of the present invention includes a mounting frame 10, a first-stage deployment frame 20, a second-stage deployment frame 30, a winding net 40 and the above-mentioned fixing assembly.

[0067] Both of the two fixed seats 1 in the fixing assembly are fixed on the mounting frame 10. The mounting frame 10 is an overall metal frame and can be installed by replacing the anti-collision beam of the vehicle. Its installation method is the same as that of the vehicle anti-collision beam. On the mounting frame 10, a vehicle bumper is installed. The vehicle bumper covers the outside of the mounting frame 10 and is fixed to the mounting frame 10 by bolts. An air intake grille is provided on the bumper. The fixed seat 1 and the mounting frame 10 can be directly fixed by a plurality of bolts, or the fixed seat 1 and the mounting frame 10 can be directly welded together.

[0068] On the mounting frame 10, a connecting rod is further provided. The connecting rod is arranged below the two fixing seats 1 and is parallel to the ground. One end of the first-stage unfolding frame 20 is arranged on the connecting rod and is hinged to the mounting frame 10 through the connecting rod. The first-stage unfolding frame 20 can be unfolded by rotating towards the ground through the connecting rod, or folded to the outside of the mounting frame 10.

[0069] The second-stage unfolding frame 30 is hinged to the other end of the first-stage unfolding frame 20 and can be folded between the first-stage unfolding frame 20 and the mounting frame 10, or flipped and unfolded together with the first-stage unfolding frame 20. The first-stage unfolding frame 20 can extend the unfolding length of the second-stage unfolding frame 30, enabling the driver to more easily move the second-stage unfolding frame 30 to the rear wheel of the vehicle to be captured during the capture process, while avoiding direct collision due to a small vehicle distance.

[0070] The winding net 40 is fixed to the other end of the rope body 4 and is detachably arranged on the second-stage unfolding frame 30. Specifically, an adhesive tape can be arranged inside the second-stage unfolding frame 30, and the winding net 40 is fixed to the second-stage unfolding frame 30 by an adhesive method similar to Velcro. After the winding net 40 is wound around the tire of the vehicle to be captured, the winding net 40 can be detached from the second-stage unfolding frame 30. During the capture process, the second-stage unfolding frame 30 moves to the outside of the rear wheel of the vehicle to be captured, the winding net 40 contacts the tire, and is wound around the vehicle tire under the rotation of the tire. The winding net 40 is fixed to the vehicle tire. At this time, the police vehicle brakes, and after the folded rope body 4 is unfolded to the longest state, the vehicle to be captured can be gradually forced to stop.

[0071] In the above embodiment, the first-stage unfolding frame 20 includes a connecting frame 201, a mesh plate 202, and a first elastic member 203. The two ends of the connecting frame 201 are respectively hinged to the mounting frame 10 and the second-stage unfolding frame 30. The mesh plate 202 is fixed to the connecting frame 201, making the connecting frame 201 form a plate-shaped member as a whole. After the connecting frame 201 is folded, the mesh plate 202 can block the rope body 4, avoiding problems such as entanglement caused by the rope body 4 touching external objects, and at the same time improving the overall aesthetics of the vehicle arrester. The mesh holes on the mesh plate 202 allow air to flow, avoiding blocking the intake of the vehicle air conditioner. The two ends of the first elastic member 203 are respectively arranged on the connecting frame 201 and the mounting frame 10. During the unfolding process of the first-stage unfolding frame 20, the first elastic member 203 can push the connecting frame 201 to rotate and open on the mounting frame 10. Specifically, the number of the first elastic members 203 is two and they are symmetrically arranged on the connecting frame 201, enabling the connecting frame 201 to be stably unfolded. The first elastic member 203 is preferably a nitrogen spring. The connecting frame 201 is unfolded by the expansion deformation of the first elastic member 203, or the connecting frame 201 is rotated, causing the first elastic member 203 to be compressed, thereby folding the connecting frame 201.

[0072] In the above-described embodiment, the secondary deployment frame 30 includes two fork frames 301 and two second elastic members 302. Both fork frames 301 are hinged to the primary deployment frame 20, specifically to the connecting frame 201 of the primary deployment frame 20. One end of each of the two second elastic members 302 is provided on the primary deployment frame 20, and the other ends of the two second elastic members 302 are respectively hinged to the two fork frames 301. The two ends of the second elastic member 302 are respectively hinged to the fork frame 301 and the connecting frame 201. When the fork frame 301 needs to be deployed, the second elastic member 302 can push the fork frame 301 to deploy. Conversely, during the process of the fork frame 301 being pushed and folded by an external force, the second elastic member 302 contracts to allow the fork frame 301 to be folded. The number of the second elastic members 302 is two, and they are symmetrically arranged on the connecting frame 201 and the two fork frames 301. The second elastic member 302 is preferably a nitrogen spring.

[0073] The winding net 40 is arranged between the two fork frames 301. A cross plate is also arranged between the two fork frames 301. Both ends of the cross plate are welded to the two fork frames 301, so that the two fork frames 301 are integrated, preventing the winding net 40 from being unstably connected due to asynchronous deployment of the two fork frames 301 and affecting normal capture operations.

[0074] It should be noted that after both the first elastic member 203 and the second elastic member 302 are selected as nitrogen springs, in order to prevent the primary deployment frame 20 from hitting the mounting frame 10 too quickly during the deployment process, the deployment thrust of the first elastic member 203 should be at least 5 N greater than the deployment thrust of the second elastic member 302, so as to prevent problems such as paint peeling or deformation caused by the primary deployment frame 20 hitting the mounting frame 10 during the deployment process.

[0075] In order to prevent the primary deployment frame 20 and the secondary deployment frame 30 from colliding with the mounting frame 10 due to excessive folding during the folding process, two buffer members 50 are also provided on the mounting frame 10. Both of the two buffer members 50 are fixed on the mounting frame 10. The buffer member 50 has an elastic movable end 501. When the primary deployment frame 20 and the secondary deployment frame 30 are folded, the secondary deployment frame 30 will contact the elastic movable end 501 of the buffer member 50 and slightly squeeze the elastic movable end 501. Supported by the elastic movable end 501, the secondary deployment frame 30 cannot directly contact the mounting frame 10, avoiding mechanical collisions caused by direct contact.

[0076] In this embodiment, in order to facilitate the installation of the connecting belt 2 and the rope body 4 onto the vehicle arrester, a placement rack 60 is further provided. The placement rack 60 is fixed on the mounting rack 10 and is located between the two fixing seats 1, and is used for placing the connecting belt 2 and the stacked rope body 4. When installing the connecting belt 2, the connecting belt 2 can be laid flat on the placement rack 60 as a whole, and then the two ends of the connecting belt 2 are respectively inserted into the two fixing seats 1 for fixation in sequence. At this time, with the support of the placement rack 60, the rope body 4 can be stacked onto the connecting belt 2. By providing the placement rack 60, the installation operation of the connecting belt 2 and the rope body 4 can be facilitated.

[0077] In this embodiment, an electric lock 71 and a lock hook 72 are also provided. The electric lock 71 is fixed on the mounting rack 10, and the lock hook 72 is fixed on the first-stage deployment rack 20. After the first-stage deployment rack 20 and the second-stage deployment rack 30 are folded to the outside of the mounting rack 10, the lock hook 72 is inserted into the electric lock 71, and the electric lock 71 fixes the lock hook 72, thereby folding and fixing the first-stage deployment rack 20 and the second-stage deployment rack 30. The electric lock 71 provided can be an electromagnetic lock, and its switch is set inside the vehicle. By pressing the switch of the electric lock 71 inside the vehicle, the first-stage deployment rack 20 and the second-stage deployment rack 30 can be opened with one key.

[0078] It should be noted that in this embodiment, when the first-stage deployment rack 20 and the second-stage deployment rack 30 are folded, the second-stage deployment rack 30 can be manually flipped first so that it is folded to the outside of the first-stage deployment rack 20, and then the second-stage deployment rack 30 is folded.

[0079] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
