[0021] DETAILED DESCRIPTION

[0022] ​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.

[0023] like Figures 1-6 As shown, this embodiment provides a police vehicle blocking device, including a frame 100. The frame 100 has a tetrahedral structure and is formed by connecting support plates 1 located at each edge of the tetrahedron. In this embodiment, there are six support plates 1, which are made of stainless steel. The cross-section of the six support rods 1 is V-shaped or semi-circular. In this embodiment, the cross-section of the support rods 1 is V-shaped, and their lengths are all the same. Thus, any one of the four faces of the frame 100 is an equilateral triangle. Reflective strips 11 are attached to the support frame 1 to improve the visibility of the device at night or in low visibility conditions, which can serve as a warning to vehicles and prompt them to stop. The strips can be made of highly reflective materials to enhance their warning effect.

[0024] The frame 100 has four supporting legs 2 at its four apex corners, also made of stainless steel. Three supporting legs 2 are provided at each of the four apex corners of the frame 100, and these three supporting legs 2 are axially symmetrically distributed at each apex corner. The supporting legs 2 are welded to the connection points of adjacent support plates 1. Each supporting leg 2 has a sheet-like structure and is perpendicular to each face of a regular tetrahedron. For example, the supporting leg 2 is a triangular structure, preferably a right triangle. Each supporting leg 2 has at least one fulcrum 21. Figure 2 As shown, for example, one fulcrum 21 is set, the right-angled side of the support leg 2 is connected to the frame 1, and the angle formed by the other two sides constitutes a fulcrum 21; for example, two fulcrums 21 are set, such as... Figure 3 As shown, each support leg 2 includes two individual units 22, which are distributed along the connecting line at the connection point and partially overlap to form two support points 21, or, as... Figure 4 As shown, the support leg 2 has a notch 23, which is a triangular block structure that gradually narrows from the hypotenuse of the support leg 2 towards the connection edge with the frame 100. The notch 23 and the right-angled side of the support leg form two fulcrums 21; for example, three fulcrums 21 are provided, each support leg 2 includes three individual units, the three individual units are distributed along the connecting line at the connection point and partially overlap, forming three fulcrums 21, or, as... Figure 5 As shown, the support leg 2 has two consecutive notches 23. The notches 23 are triangular block structures that gradually narrow from the hypotenuse of the support leg 2 toward the connection side with the frame 100. The two notches 23 and the right-angled side of the support leg form three support points 21. One or more support points can be set according to actual needs.
