Abstract

The utility model relates to a vehicle passing roadblock device, in particular to a temporary roadblock device enabling vehicles to pass unidirectionally, which consists of a seat body, nails, pin shafts and springs. The technical scheme is that a row of small grooves are arranged on the seat body, and the nails, the pin shafts and the springs are installed in each small groove. In a natural state, the nails can rotate clockwise around the pin shafts but cannot rotate anticlockwise, one ends of the springs are connected with the nails, and the other ends of the springs are connected with the bottoms of the small grooves. The springs are compression springs so that the nails extend out of the small grooves in the natural state. When vehicles pass through a roadblock from the vehicle passable direction A, vehicle tyres press on the nails, the nail rotate clockwise around the pin shafts 5, the springs are compressed, the nails are hidden in the small grooves, and the vehicles pass through the roadblock smoothly. After the vehicles pass through the roadblock, the nails return to the natural state under the action of the springs. When the vehicles pass through the roadblock from the vehicle passable direction B, the vehicle tyres press on the nails, the nail cannot rotate anticlockwise around the pin shafts and are pricked into the vehicle tyres, and the vehicles are prevented from passing through the roadblock.

Description

But the interim roadblock of a kind of one-way trip

Technical field

The utility model relates to a kind of vehicle pass-through roadblock, but is the interim roadblock of a kind of one-way trip specifically.

Background technology

In traffic administration or police's law enforcement; Sometimes only need unidirectional vehicle to be checked temporarily or intercepted; In order to prevent that vehicle from dash closing by force, can place certain erosion control and close facility, but the present interim roadblock current roadblock that all is two-way restriction; Use very inconvenience, but therefore need the interim roadblock of a kind of one-way trip.

Summary of the invention

But the purpose of the utility model provides the interim roadblock of a kind of one-way trip.

The technical scheme of the utility model: on pedestal (1), have row's sulculus (3), nail (2), bearing pin (5), spring (4) are installed, in each sulculus (3) under nature; Nail (2) can clockwise rotate around bearing pin (5); But can not rotate counterclockwise, an end of spring (4) is connected with nail (2), and the other end is connected with the bottom of sulculus (3); Spring (4) is a compression spring, and nail (2) is stretched out from sulculus (3).

Beneficial effect: use this technical scheme, the vehicle pass-through of the direction that can guarantee to pass through is without hindrance, and need not move any roadblock.

Description of drawings

But Fig. 1 interim roadblock overall schematic that is one-way trip.1-pedestal, 2-nail, 3-sulculus.

Fig. 2, Fig. 3 are respectively the sketch mapes of vehicle this roadblock work when passing through to pass through direction and impassabitity direction.4-spring, 5-bearing pin, 6-vehicle tyre, the v-vehicle tyre direction of motion.

The specific embodiment

To combine the utility model Figure of description below, the technical scheme among the utility model embodiment will be carried out clear, intactly description.

But Fig. 1 interim roadblock overall schematic that is this one-way trip.When but the interim roadblock of one-way trip is somebody's turn to do in setting, should note the correct of direction, the open to traffic of A direction, the vehicle of B direction can not pass through.

Fig. 2 is the sketch map of vehicle this roadblock work when passing through to pass through direction.When vehicle can pass through direction A when this roadblock from vehicle, vehicle tyre 6 is pressed on the nail 2, and nail 2 clockwise rotates around bearing pin 5; Spring 4 is compressed, and nail 2 is hidden in the sulculus 3, and vehicle is smoothly through this roadblock; After vehicle is logical, under the effect of spring 4, nail 2 restore nature states.

Fig. 3 is the sketch map of vehicle this roadblock work when passing through the impassabitity direction.When vehicle from vehicle impassabitity direction B when this roadblock, vehicle tyre 6 is pressed on the nail 2, nail 2 can not rotate counterclockwise around bearing pin 5, nail 2 will penetrate in the vehicle tyre 6, stop vehicle through this roadblock.

Claims

1. but interim roadblock of one-way trip; It is characterized in that: on pedestal (1), have row's sulculus (3), nail (2), bearing pin (5), spring (4) are installed, in each sulculus (3) under nature; Nail (2) can clockwise rotate around bearing pin (5); But can not rotate counterclockwise, an end of spring (4) is connected with nail (2), and the other end is connected with the bottom of sulculus (3); Spring (4) is a compression spring, and nail (2) is stretched out from sulculus (3).
