Abstract

The utility model discloses a tumbler roadblock, which comprises a roadblock body with a tumbler structure at the bottom. There is also an alarm connected electrically with the proximity switch. The bottom of the roadblock body of the utility model has a tumbler structure, which will automatically return to its position after being toppled under force. When the roadblock body is tilted to a certain angle, after the distance between the proximity switch and the sensor reaches a preset value, it is electrically connected to the proximity switch. The siren is turned on to send out an alarm to warn the driver. The warning effect is good, especially suitable for the night when the light is not good; the utility model also strengthens the stability of the roadblock body through the base, so that the roadblock body is not easy to be displaced due to force.

Description

tumbler barricades

technical field

The utility model relates to a roadblock, in particular to a tumbler roadblock.

Background technique

Barricades are props placed on the road to prevent vehicles from passing. Commonly used barricades are hollow conical structures. When in use, they can be placed directly on the ground. This kind of barricades are easy to topple under force. At present, there are some tumbler barricades with a tumbler structure at the bottom of the barricade. This kind of tumbler barricade will automatically return to its position after being tilted under force, and will not topple, but there are also some shortcomings. displacement, away from the initial position. In addition, the current roadblocks have the disadvantage that the warning effect is not obvious. Because the roadblocks are generally hollow plastic structures and light in weight, when the light is poor at night, the roadblocks are not easy to be observed, and the driver will not have a clear feeling after the vehicle hits. , does not play a warning role.

Utility model content

The technical problem to be solved by the utility model is: to provide a tumbler roadblock with strong warning effect and less likely to be displaced under force.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a tumbler roadblock, including a roadblock body with a tumbler structure at the bottom, characterized in that it also includes a base, the roadblock body is movably connected to the base, and a proximity switch is provided on the roadblock body , the base is provided with an inductor matched with the proximity switch, and the roadblock body is also provided with an alarm electrically connected with the proximity switch.

Further, a hemispherical groove is provided in the middle of the base, and the barricade body is connected in the hemispherical groove through a spring.

Further, the base is provided with a plurality of drainage grooves, and the drainage grooves communicate with the hemispherical groove.

Further, the top of the roadblock body is provided with a rope fixing structure.

Further, the rope fixing structure is a hook.

Further, multiple layers of luminous strips are arranged at intervals on the surface of the roadblock body.

The beneficial effects of the utility model are: the bottom of the barricade body of the utility model has a tumbler structure, which will automatically return to its position after being toppled under force, and when the barricade body tilts to a certain angle, the distance between the proximity switch and the sensor reaches the preset After the value is set, the siren electrically connected to the proximity switch will turn on and give an alarm to warn the driver. The warning effect is good, especially suitable for the night when the light is not good; It is not easy to be displaced by force.

detailed description

In order to facilitate understanding of the utility model, the utility model is further described below in conjunction with the accompanying drawings.

As shown in Figure 1, the utility model does not improve the traditional tumbler roadblock, but a proximity switch 3 is provided on the roadblock body 1 with a structure that does not reach the tumbler at the bottom, and a base 2 is added at the same time. The sensor 4 that the proximity switch 3 cooperates is located at the top of the roadblock body 1 and an alarm 5 is set, and the alarm 5 is controlled by the proximity switch 3; the proximity switch 3 and the sensor 4 are respectively provided with a In Fig. 1, it is only shown in one direction for the sake of illustration. When the barricade body 1 is tilted under force, the proximity switch 3 on the tilted direction gradually approaches the corresponding sensor 4. When the distance between the two reaches the predetermined When setting vertically, proximity switch 3 controls siren 5 to send the alarm, and the driver is warned.

In the middle of the base 2 is a hemispherical groove, the roadblock body 1 is placed in the hemispherical groove, and the bottom of the roadblock body 1 is connected with the base 2 by a spring, although the roadblock body 1 will be tilted when it is hit, it will be affected by the impact. The connection effect of the spring can not break away from the outside of the base 2.

Since water may accumulate in the hemispherical groove of the base 2, a plurality of drainage grooves 6 are provided on the base 2, and the drainage grooves 6 communicate with the hemispherical groove for discharging accumulated water.

In order to further strengthen the stability of the tumbler roadblock, a rope fixing structure 7 is provided on the top of the roadblock body 1, and a plurality of tumbler roadblocks arranged can be connected by ropes; in the utility model, a hook with a simple structure is selected as the rope fixing structure 7.

The surface of the roadblock body 1 is provided with multiple layers of luminous strips 8 at intervals.
