Description

Technical Field

[0001] This utility model relates to the field of police equipment technology, and in particular to a knife-resistant tire-puncture stopper. Background Technology

[0002] The security field needs to develop a portable riot control device with stable tire-puncture capability to quickly respond to sudden emergencies.

[0003] Currently, although some existing technologies incorporate sharp structures into riot control forks, their actual tire-puncturing effect is limited or even nonexistent. In addition, a few existing technologies integrate tire-puncturing structures into riot control forks to respond promptly to sudden vehicle-related injuries during routine duty. For example, patent CN204495175U discloses an anti-knife tire-puncturing fork with several hollow spikes on the main shaft, and patent CN115613496A discloses a portable police vehicle stopper with tire-puncturing steel needles on the side facing the tire. However, the tire-puncturing structures in these existing technologies are simple and lack specific optimization for different vehicle-stopping scenarios, resulting in poor adaptability and stability in actual use. Utility Model Content

[0004] The main technical problem to be solved by this utility model is to provide a tire-puncture prevention device that improves the tire-puncture prevention effect of the device on vehicles committing assault.

[0005] To solve the above-mentioned technical problems, this utility model provides a tire burst prevention device, including a gripping rod and a restraining fork connected to one end of the gripping rod; the restraining fork is configured with an opening facing away from the gripping rod; the restraining fork is provided with a plurality of spikes at intervals in the length extension direction; the spikes include a plurality of first spikes;

[0006] Using the plane or curved surface where the constraint fork is located as the reference plane: for the first spike extending toward the same side of the reference plane, part extends obliquely toward one side of the opening, and the other part extends obliquely toward the side away from the opening.

[0007] In a preferred embodiment, the first spike is a hollow structure.

[0008] In a preferred embodiment, the first spike forms an angle of 45° to 75° with the reference plane.

[0011] In a preferred embodiment, the blocking section is straight, and the first spike is perpendicular to the blocking section.

[0012] In a preferred embodiment, the second spike is perpendicular to the reference plane.

[0013] In a preferred embodiment, the distance between any two adjacent spikes, or the distance from any free end of the constraint fork to the nearest spike, is no greater than 5 centimeters.

[0014] In a preferred embodiment, on either side of the reference plane, the first spikes extending toward the opening side and the first spikes extending away from the opening side are either coplanar or adjacent to each other to form a first spike group.

[0015] In a preferred embodiment, the constraint fork is provided with at least one first spike group on each side of the connection point with the gripping rod.

[0016] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0017] The anti-knife tire puncture stopper provided by this utility model has the following advantages: (1) Significantly improves tire puncture stability.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0028] like Figures 1-6As shown, this utility model embodiment provides a knife-resistant tire-puncture riot control device. In addition to its basic riot control functions of resisting knife attacks and isolating and restraining vehicles, it can also stably puncture the tires of vehicles used in riots. The knife-resistant tire-puncture riot control device includes a gripping rod 5 and a restraining fork 1 connected to one end of the gripping rod 5. Figure 1 As shown, the main body of the restraint fork 1 is a roughly U-shaped or crescent-shaped rod with an opening 4 facing away from the gripping rod 5. The opening 4 is used to restrict the perpetrator's movement space. Preferably, the restraint fork 1 and the gripping rod 5 are arranged coplanarly.

[0029] The constraint fork 1 is provided with a plurality of spikes 2 at intervals along its length extension direction. Each spike 2 includes a plurality of first spikes 21 extending obliquely from the constraint fork 1. In this embodiment, "oblique" is defined as: the first spikes 21 extend laterally from the constraint fork 1 and are neither perpendicular to nor coplanar with the plane or curved surface on which the constraint fork 1 is located. For ease of description, as... Figure 2 As shown, the plane or curved surface where the constraint fork 1 is located is defined as the reference surface 3. Preferably, the angle between the first spike 21 and the reference surface 3 is 45° to 75°. In this embodiment, the angle between the first spike 21 and the reference surface 3 is preferably 60°.

[0030] like Figure 5 As shown, some existing tire puncture prevention devices, when placed on the ground, have puncture spikes that are nearly vertical. This leads to the problem that the angle between the puncture spike and the tire surface is small when they contact each other, resulting in a weaker frictional coiling effect F1 (the tendency for the tire to coil into the bottom of the tire) and a dominant horizontal thrust F2. This makes unsecured tire puncture prevention devices easily pushed by the wheels, hindering tire puncture prevention. Therefore, the anti-knife tire puncture prevention device provided in this embodiment of the invention has the first spike 21 set at an angle. For example... Figure 6 As shown, when the first spike 21 contacts the tire, it is approximately perpendicular to the tire surface, increasing the frictional banding effect F1 of the tire on the first spike 21. Since the constraint fork 1 cannot be lifted, under the combined action of the horizontal thrust F2 from the tire and the frictional banding effect F1, the first spike 21 stably penetrates the tire. The first spike 21 is designed as a hollow structure to deflate the tire. From a macroscopic perspective, when the first spike 21 contacts the tire, it points towards the center of the wheel, precisely aligning with the direction of the tire's action on itself, achieving stable tire puncture.

[0031] Furthermore, to address the possibility of reversing, the first spike 21 extends bidirectionally to puncture tires of vehicles approaching from different directions. Specifically, for the first spike 21 extending towards the same side of the reference plane 3, some of the first spike 21 extends obliquely towards one side of the opening 4, while the other part extends obliquely away from the opening 4. For ease of understanding, a practical application scenario will be used as an example. Figure 1 , Figure 4 As shown, when the constraint fork 1 is placed horizontally, that is, when the reference surface 3 is in a horizontal state, among the first spikes 21 located above the reference surface 3, a portion of the first spikes 21 extend obliquely upward toward the side closer to the opening 4, while another portion of the first spikes 21 extend obliquely upward toward the side away from the opening 4. The same applies to the first spikes 21 located below the reference surface 3.

[0032] In a similar embodiment, all spikes 2 utilize the first spike 21, achieving synergistic anti-knife and stabilizing tire burst prevention. In this embodiment, the spikes 2 further include several second spikes 22. For example... Figure 1 As shown, the restraint fork 1 includes a vehicle-stopping section 11 located in the middle and two extension sections 12 located at both ends of the vehicle-stopping section 11. The vehicle-stopping section 11 is straight and perpendicularly connected to the gripping rod 5. The first spike 21 is located within the vehicle-stopping section 11 and is perpendicular to the restraint fork 1. Thus, the projection of the first spike 21 onto any cross-sectional plane of the vehicle-stopping section 11 is approximately an "X"-shaped obliquely intersecting distribution. Preferably, on any side of the reference plane 3, the first spikes 21 extending towards the opening 4 and the first spikes 21 extending away from the opening 4 are either coplanar or adjacent to each other, forming a first spike group 210. A plurality of first spike groups 210 are spaced apart along the length direction of the vehicle-stopping section 11. Preferably, at least one first spike group 210 is provided on each side of the vehicle-stopping section 11 at the connection point with the gripping rod 5. Furthermore, in this embodiment, two sets of the first spikes 210 are respectively provided on both sides of the connection between the vehicle blocking section 11 and the gripping rod 5.

[0033] A plurality of second spikes 22 are spaced apart at least along the length of the extension 12. In this embodiment, the second spikes 22 are also provided at the middle position of the blocking section 11. Preferably, the second spikes 22 are perpendicular to the reference plane 3. Further, the second spikes 22 are mirror images of the reference plane 3. Based on the above structure, the first spikes 21 and the second spikes 22 have a similar layout on both sides of the restraint fork 1, so that in an emergency, both sides of the restraint fork 1 can be used equivalently to knock off the attacker's weapon or to place it on the ground to puncture tires. Figure 4As shown, on any side of the reference plane 3, the vertical height of the second spike 22 is not less than the vertical height of the first spike 21. Thus, when the riot control device is placed horizontally on the ground, several of the second spikes 22 are supported on the ground, forming multi-point support in the depth direction of the restraint fork 1, making the restraint fork 1 stably "lie flat on the ground". When the tire presses down on the first spike 21, due to the lever effect, the restraint fork 1 is not lifted or wobbled back and forth, allowing the first spike 21 to stably pierce the tire. In the length extension direction of the restraint fork 1, the second spikes 22, in conjunction with the first spikes 21, control the continuous length of the restraint fork 1 without spikes 2, preventing the perpetrator from seizing the anti-knife tire-puncture riot control device by grasping the restraint fork 1. Specifically, in this embodiment, the distance between any two adjacent spikes 2, or the distance from any free end of the restraint fork 1 to the nearest spike 2, is not greater than 5 centimeters.

[0034] like Figure 3 As shown, in this embodiment, the gripping rod 5 and the constraint fork 1 are detachably connected. Specifically, a connecting sleeve 13 extends from the middle of the constraint fork 1 on the side opposite to the opening 4. One end of the gripping rod 5 is inserted into the connecting sleeve 13. A clearance through hole 131 is provided through the connecting sleeve 13 along its thickness direction. A spring plunger 51 is provided radially on the gripping rod 5. The spring plunger 51 locks or unlocks the limiting fit between the gripping rod 5 and the constraint fork 1 by entering or exiting the clearance through hole 131. A shoulder 52 is provided circumferentially on the gripping rod 5, and the distance from the shoulder 52 to the spring plunger 51 matches the distance from the clearance through hole 131 to the free end of the connecting sleeve 13. Further, the gripping rod 5 adopts a segmented structure, and the connection method between each segment is the same as the connection method between the gripping rod 5 and the constraint fork 1, which will not be described in detail here. For those skilled in the art, the connection methods between the constraint fork 1 and the gripping rod 5, and between the segments of the gripping rod 5, can be varied in many ways, such as threaded connections, telescopic sleeves, etc. Since the structure and connection method of the gripping rod 5 are not core features for solving the technical problem of this application, any non-inventive modifications made thereto should not depart from the protection scope of this utility model.

[0035] In summary, the anti-knife tire burst stopper provided by this utility model embodiment has the following technical advantages: (1) Significantly improves tire burst reliability. The obliquely extending first spike 21 can accurately meet the direction of the tire's action on itself when it contacts the tire, and changes the overall action of the tire on the first spike 21 by increasing the friction coiling action F1, thereby more stably and efficiently piercing the tire for damage. (2) Possesses bidirectional tire burst capability. Each first spike group 210 consists of two first spikes 21 arranged obliquely. This layout ensures that no matter whether the vehicle is driving forward or reversing, there is always one spike 2 that can effectively pierce the tire, thereby improving the adaptability and interception success rate of the anti-knife tire burst stopper. (3) Possesses high working stability. The second spike 22 is higher than the first spike 21, forming multi-point ground support, so that the restraint fork 1 is stably lying on the ground, avoiding the anti-knife tire burst stopper from tilting up due to the pressure of the tire, thereby improving tire burst stability. (4) Achieves multiple uses with one device. Through structural optimization, the anti-riot steel fork is cleverly endowed with the function of quickly puncturing tires and stopping vehicles.

[0036] The above description is merely a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All technically equivalent modifications made based on the content of the present utility model specification shall fall within the protection scope of the present utility model.
