[0002] A car blocker is a common vehicle blocking device in indoor and outdoor parking lots. It is used to limit the position of vehicles when they are parked to prevent collisions between vehicles or between vehicles and people, walls and buildings.

[0003] At present, after the conventional logistics truck trailer arrives at the factory's designated loading and unloading space, the driver is required to place the truck trailer wheel stoppers (manually). The styles are not uniform, not easy to operate, and there is a possibility of non-standardization and forgetfulness in the process, which poses a great safety hazard.

[0004] The difficulty in solving the above technical problems lies in that the current truck stoppers are wheel stoppers, which are provided by each truck or logistics company, and have different styles, materials, damping strength, volume, placement, and actual functional effects recognized by operators. Therefore, the current situation of unified wheel stoppers is due to the fact that there are many logistics companies, many vehicles, a large number of equipment, and the possibility of loss after equipment.

[0005] The significance of solving the above technical problems is: the truck blocker is installed in each parking space, eliminating the uncontrollability of the placement of the trucks carried by the trucks, reducing the number of inspections and inspections by personnel, and achieving complete locking without special confirmation by personnel, so that the vehicle will not slip. All parking spaces are managed in a unified standard, and the safety standard facilities are neatly arranged and the safety facilities in the industry are original. Summary of the invention

[0032] In this embodiment, a concrete layer is provided inside the damping block 1; a connecting block 3 and a connecting plate 4 are welded from top to bottom on the rear side of the damping block 1, and a rocker arm 5 is provided between the connecting block 3 and the connecting plate 4;

[0033] In this embodiment, a core shaft 2 is passed through the front end of the rocker arm 5, the lower end of the core shaft 2 is connected to the connecting plate 4, the upper end of the core shaft 2 protrudes out of the connecting block 3, and a spring 8 is arranged on the outer side of the core shaft 2;

[0034] In this embodiment, a sensor is provided on the mandrel 2, and the sensor is electrically connected to a warning light and a buzzer; the mandrel 2 has manual operation conditions, and can be locked and unlocked within a rotation range of 120°. The sensor is a 220V external force trigger, a release self-returning contact switch, and a connecting wire is connected in series with the same voltage adapter buzzer and warning light. The principle of the sensor is as follows Figure 4 shown.

[0035] The truck is fixed on both sides of the parking space by the fixing seat 7. When the truck reverses into the designated parking space, the truck stops reversing after the rear wheels of the truck touch the rear wheel block. The truck driver gets off the truck and manually turns the blockers on both sides toward the front of the rear wheels of the truck. After turning, the handle and the ground hole are used to lock them. After the ground hole is locked, the handle is locked at the same time (the warning light / buzzer is energized). The warning light / buzzer works to indicate that the truck is fixed and the forklift can start working.
