Description

TECHNICAL FIELD

[0001] The utility model relates to a vehicle stopper technical field, specifically a police vehicle stopper. BACKGROUND

[0002] The police vehicle stopper is widely used, and is mainly used for intercepting escaped vehicles or violent collision vehicles to avoid loss of personnel and property. In recent years, there have been many cases of police personnel being injured due to escaped drunk driving punishment.

[0003] The commonly used police vehicle stopper mainly has the following types: one is a fixed vehicle stop device, which is usually raised from the ground in a hydraulic telescopic manner to block the car, but it needs to be arranged in advance and the construction is complicated, it is not movable, and it is not suitable for checking drunk driving and temporary control scenes; two is to lay vehicle stop nails on the ground, but the vehicle stop nails have poor braking performance, and the vehicle tires often lose control after being punctured, which is highly dangerous; three is a vehicle stop net, which also needs to be set up in advance, is complicated to operate, and has high manufacturing cost; four is to block the vehicle by using an L-shaped vehicle stop frame, such as the portable vehicle stopper unit assembly and related portable vehicle stopper disclosed in Chinese patent application No. 201910139717.7, but it has the problems of complex structure, inconvenient arrangement, large size, and inconvenient carrying.

[0004] Therefore, there is an urgent need to design a police vehicle stopper that is small in size, convenient to carry, easy to disassemble, and can effectively intercept small cars for inspection or violent collision. CONTENT OF THE UTILITY MODEL

[0005] (I) Technical problems solved

[0006] The utility model provides a police vehicle stopper, which aims to solve the problems raised in the background art.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0008] A police vehicle stopper, comprising a fixed base body, four hollow support sleeves are fixedly connected to the fixed base body, the included angle of the axes of any two adjacent support sleeves is the same, and a support rod is detachably inserted into each support sleeve; a fastening nut is fixedly connected to the outer circumference of each support sleeve, a sleeve hole coaxial with the corresponding fastening nut is formed in the circumference of the support sleeve, and a fastening bolt is threadedly connected in the fastening nut and abuts against the support rod through the sleeve hole to fix the support rod in the support sleeve.

[0009] As a preferred technical scheme of the present application, a limiting groove is formed at one end of the support rod inserted into the support sleeve, and one end of the fastening bolt can be clamped into the limiting groove.

[0010] As a preferred technical solution of this application, the limiting groove is an annular groove structure.

[0011] As a preferred technical solution of this application, a reinforcing sleeve is formed by extending the outer circumference of the support rod outside the support sleeve outward. When the support rod is fixedly inserted into the support sleeve, the opposite end faces of the reinforcing sleeve and the support sleeve abut against each other.

[0012] As a preferred technical solution of this application, a rotating handle is provided at one end of the fastening bolt outside the fastening nut.

[0013] As a preferred technical solution of this application, a tire-puncturing spike is provided on the support rod.

[0014] As a preferred technical solution of this application, reflective stickers are adhered to the outer circumference of the support rod.

[0015] 1. This utility model, by setting a fixed base and a support sleeve, facilitates the welding of the support sleeve to the fixed base. Furthermore, by tightening nuts and bolts, the support rod can be quickly assembled and disassembled within the support sleeve. This results in a compact, portable, and quick-assembly / disassembly design. In use, when thrown in front of an fleeing vehicle, the utility model will roll under the vehicle upon impact, thus supporting it and preventing its escape. Because the support rod is detachable, it can be designed in various lengths to suit different vehicles, and its specific length can be adjusted to adapt to the specific needs of the vehicle being intercepted.

[0016] 2. This utility model, by setting a limiting groove, can limit the fastening bolt's position on the support rod, preventing the support rod from detaching from the support sleeve upon impact. This avoids the potential problems of existing technology where the support rod is directly threaded into the fixed base; impacts to the support rod can cause thread failure, rendering the vehicle stopper unusable and increasing interception costs. This utility model further incorporates a reinforcing sleeve, significantly reducing the shear force on the fastening bolt. Even if the support rod is bent, only the bent support rod needs to be replaced.

[0017] 3. This utility model facilitates the tightening and loosening of bolts by providing a rotating handle. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0028] See Figure 1 , 2 As shown in Figure 3, a police vehicle stopper includes a fixed base 1. In this embodiment, the fixed base 1 can be made of spherical steel or cast iron material, or of course, other shapes. This utility model uses a spherical structure to facilitate the welding of the following support sleeve 2 onto the fixed base 1.

[0029] Four hollow support sleeves 2 are welded onto the fixed base 1. Each support sleeve 2 is a cylindrical structure with open ends, one end of which is welded to the fixed base 1. The included angle between the axes of any two adjacent support sleeves 2 is the same. The four support sleeves 2 and the fixed base 1 form a regular tetrahedral structure (similar to the structure of a diamond carbon atom). A support rod 3 can be detachably inserted into each support sleeve 2.

[0030] A fastening nut 4 is welded to the outer circumference of each support sleeve 2, and the axis of the fastening nut 4 is perpendicular to the axis of the corresponding support sleeve 2. A sleeve through hole 21 coaxial with the corresponding fastening nut 4 is opened on the circumference of the support sleeve 2. The fastening bolt 5 is threaded into the fastening nut 4 and abuts against the support rod 3 through the sleeve through hole 21 to fix the support rod 3 in the support sleeve 2.

[0031] Therefore, with the above structure, when this police vehicle stopper needs to be used, the support rod 3 is inserted into a support sleeve 2, and the fastening nut 4 is rotated so that one end of the fastening nut 4 passes through the sleeve through hole 21 and presses against the support rod 3 to fix the support rod 3 inside the support sleeve 2. The other three support rods 3 can be installed in the same way. When this police vehicle stopper is not needed or needs to be carried or transported, each fastening nut 4 is loosened, and the support rod 3 is pulled out from the support sleeve 2.

[0032] Furthermore, to improve the connection strength between the fixed base 1 and each support sleeve 2, reinforcing ribs 11 can be welded between the fixed base 1 and each support sleeve 2, and between each support sleeve 2. To prevent the end of the support rod 3 from being accidentally damaged by sharp objects, a rubber sleeve 31 is fixedly fitted at the end of the support rod 3 away from the fixed base 1.

[0033] Furthermore, to facilitate the rotation of the fastening bolt 5, a rotating handle 51 is welded to one end of the fastening bolt 5 on the outside of the fastening nut 4. Example 2

[0034] See Figure 4 , 5 As shown in Figures 6 and 7, this embodiment is a further improvement on the basis of embodiment 1. This embodiment only describes the differences from embodiment 1.

[0035] In order to further improve the connection between the support rod 3 and the support sleeve 2, and to prevent the support rod 3 from detaching from the support sleeve 2 due to the limited locking force of the fastening bolt 5 on the support rod 3 when the support rod 3 is subjected to a large impact force from the car, in this embodiment, a limiting groove 32 is opened at one end of the support rod 3 inserted into the support sleeve 2, and one end of the fastening bolt 5 can be locked in the limiting groove 32.

[0036] The limiting groove 32 can have various structures, such as a groove on the outer circumference of the support rod 3 facing its axis. However, with this structure, the end of the fastening bolt 5 is difficult to insert into the groove, making assembly of the police vehicle stopper inconvenient. Therefore, in this embodiment, the limiting groove 32 is an annular groove structure, meaning it has a groove around the outer circumference of the support rod 3 along its axis. This structure allows the end of the fastening bolt 5 to easily engage within the limiting groove 32, preventing the support rod 3 from easily detaching from the support sleeve 2.

[0037] Furthermore, since the support rod 3 of this police vehicle stopper is subjected to the heavy pressure of the vehicle when blocking it, the support rod 3 at the outer opening of the support sleeve 2 is subjected to torque, which can easily cause the support rod 3 to bend. Therefore, in this embodiment, a reinforcing sleeve 33 is formed by extending the outer circumference of the support rod 3 on the outer side of the support sleeve 2. When the support rod 3 is fixedly inserted into the support sleeve 2, the opposite end faces of the reinforcing sleeve 33 and the support sleeve 2 abut against each other. It should be noted that the support rod 3 and the reinforcing sleeve 33 are integrally formed structures. The name "reinforcing sleeve 33" is only used to better illustrate the position and connection relationship between the support rod 3 and the reinforcing sleeve 33.

[0038] Furthermore, to facilitate puncturing the tires of escaped vehicles, a puncture spike 34 is welded onto the support rod 3. Reflective tape 35 is adhered to the outer circumference of the support rod 3. It should be noted that the reinforcing sleeve 33 is part of the support rod 3, and the puncture spike 34 and reflective tape 35 can also be mounted on the reinforcing sleeve 33.

[0039] The process of fixing the support rod 3 inside the support sleeve 2 in this embodiment is basically the same as in embodiment 1. When this police vehicle stopper is needed, insert the support rod 3 into one of the support sleeves 2, and rotate the rotating handle 51 of the fastening nut 4 so that one end of the fastening nut 4 passes through the sleeve through hole 21 and abuts against the limiting groove 32 of the support rod 3, and presses against the circumference of the support rod 3 in the limiting groove 32. At this time, the support rod 3 cannot be detached from the support sleeve 2 under the limiting action of the fastening bolt 5. The installation of the other three support rods 3 can be completed in the same way. When this police vehicle stopper is not needed or needs to be carried or transported, loosen each fastening nut 4 so that the fastening bolt 4 is detached from the limiting groove 32, and the support rod 3 can be pulled out from the support sleeve 2.

[0040] In actual use of this utility model, the usage methods of Embodiment 1 and Embodiment 2 are the same. That is, after each support rod 3 is inserted into the corresponding support sleeve 2 and fixed, when blocking the escape vehicle, this utility model is thrown in front of the escape vehicle. After the escape vehicle collides with this vehicle blocker, the vehicle blocker will flip to the underside of the escape vehicle chassis, thereby supporting the escape vehicle. At this time, the escape vehicle can no longer escape.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
