Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
A portable police tire retarder comprises a cylinder body 1 and a pressure relief device 2 arranged in the cylinder body 1, and blocks a vehicle when in use, as shown in figure 1. An installation cavity 19 is formed in the cylinder 1, and the pressure relief device 2 is installed in the installation cavity 19.
Referring to fig. 2 and 3, the cylindrical body 1 may be cylindrical or square, an installation opening 11 communicating with the installation cavity 19 is opened at one end of the cylindrical body 1, and a front end cover 12 is disposed on the cylindrical body 1 at a position of the installation opening 11. An adjusting opening 13 is arranged on one side of the cylinder 1 far away from the mounting opening 11, and a rear end cover 14 is arranged on one end of the cylinder 1, which is positioned at the adjusting opening 13. The cylinder 1 comprises a first arc-shaped plate 15 and a second arc-shaped plate 16, and the sections of the first arc-shaped plate 15 and the second arc-shaped plate 16 are arc-shaped; the first arc-shaped plate 15 and the second arc-shaped plate 16 are fixedly connected through a fastening screw 17.
A pressure relief opening 18 is formed in the side wall of the cylinder body 1, and when the pressure relief device 2 is used, the part of the pressure relief device, which penetrates out of the pressure relief opening 18, is used for relieving pressure of a tire.
The pressure relief device 2 comprises a switch travel rod 21 capable of moving linearly along the axis direction of the barrel 1, a pressure relief needle 22 with one end rotatably connected to the switch travel rod 21, and the free end of the pressure relief needle 22 far away from the switch travel rod 21 can rotate to penetrate out of or retract into the pressure relief opening 18. In addition, the free end of the pressure relief needle 22 is selected to be rotated in a direction away from or toward the switch stroke rod 21 in an axial direction perpendicular to the switch stroke rod 21.
In order to make the pressure release needle 22 rotate better, a connecting shaft 221 is provided inside the cylinder 1 and inside the pressure release port 18, a long groove 222 is opened on a side wall of the pressure release needle 22, and the connecting shaft 221 passes through the long groove 222. Meanwhile, the pressure relief port 18 is provided as an elongated groove, thereby facilitating the rotation of the pressure relief needle 22.
Wherein, a plurality of pressure relief needles 22 are arranged along the circumferential direction of the switch stroke rod 21 at intervals, and a plurality of groups are arranged along the length direction of the switch stroke rod 21 at intervals; the pressure relief ports 18 on the barrel 1 are matched with the pressure relief needles 22 one by one.
Meanwhile, the pressure relief device 2 further comprises an elastic element 23 which is arranged in the mounting cavity 19 and is far away from one end of the mounting opening 11, wherein one end of the elastic element 23 is abutted against the rear end cover 14, and the other end of the elastic element is abutted against the switch travel rod 21. Meanwhile, a positioning member 24 for positioning the position of the switch stroke lever 21 is provided on a side close to the mounting opening 11. When the switch stroke rod 21 moves into the cylinder 1 so that the pressure relief needle 22 is perpendicular to the side wall of the cylinder 1, the positioning piece 24 positions the switch stroke rod 21.
When the pressure relief device is used, the switch travel rod 21 is moved by manually operating the pressing handle 211, so that when the switch travel rod 21 moves into the mounting cavity 19, the pressure relief needle 22 can be rotated away from the switch travel rod 21, and the free end of the pressure relief needle 22 penetrates out of the pressure relief opening 18.

Further, through the rear end cap 14, it is convenient at first to adjust the elastic force of compression spring 231 properly, simultaneously, conveniently opens rear end cap 14 and changes the compression spring 231 of inside.
Further, an annular groove 212 is formed in the switch stroke rod 21 at a side close to the front cover 12, and the annular groove 212 cooperates with the positioning member 24 to position the switch stroke rod 21.
The positioning element 24 comprises an elastic plate 241 fixed on the inner wall of the cylinder 1 and an L-shaped connecting rod 242 fixed on the side of the elastic plate 241 remote from the inner wall of the cylinder 1, wherein the L-shaped connecting rod 242 comprises an operating rod section 2421 parallel to the length direction of the switch stroke rod 21 and a positioning rod section 2422 perpendicular to the switch stroke rod 21, wherein the end of the positioning rod section 2422 abuts on the side wall of the switch stroke rod 21. When the switch travel rod 21 is moved in the length direction thereof and is positioned such that the pressure relief needle 22 passes out of the pressure relief opening 18 and the pressure relief needle 22 is positioned perpendicular to the switch travel rod 21, the positioning rod section 2422 is inserted into the annular groove 212.
In addition, an operation hole 121 is formed in the front end cover 12, and one end of the operation rod section 2421, which is far away from the positioning rod section 2422, penetrates through the operation hole 121, so that a user can conveniently operate the operation rod section 2422. It should be noted that the diameter of the operation hole 121 should be larger than that of the operation rod section 2421, so that the positioning rod section 2422 can be disengaged from the annular groove 212 due to the elastic force of the elastic plate 241 when swinging to one side.
The barrel 1 is provided with a warning lamp 3, and when the pressure relief needle 22 is vertical to the barrel 1, the warning lamp 3 automatically lights. The warning effect is achieved through the arranged warning lamp 3.
The power supply 31 is arranged in the barrel 1, the metal pressing sheet 32 is arranged in the annular groove 212, the positioning rod section 2422 is made of a conductive material, the power supply 31 is connected with the warning lamp 3, the positioning rod section 2422 and the metal pressing sheet 32 in series through a conducting wire, no conducting wire is communicated between the positioning rod section 2422 and the metal pressing sheet 32, and when the positioning rod section 2422 is abutted against the annular groove 212, the positioning rod section 2422 is in contact with the metal pressing sheet 32 to form a closed loop, so that the warning lamp 3 is lightened.
Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
