Description

Technical Field

[0001] The utility model relates to the technical field of vehicle restriction, in particular to a park vehicle restriction device. Background Art

[0002] Park vehicle restriction devices are a set of systems or equipment designed specifically for park traffic management, which are intended to limit or control the entry of vehicles of certain types or under certain conditions into the park. These devices combine a variety of technologies and methods to ensure the safety, order and smoothness of traffic in the park;

[0003] After checking the public (announcement) number: CN220132786U, a vehicle restriction device in a park is disclosed. This technology discloses technical solutions such as "adding a motor, a first bevel gear, a second bevel gear, a drive screw, a thread groove, a movable frame and other structures to cooperate with each other", which has technical effects such as "making the distance between the two second connecting columns adjustable, thereby limiting the width of vehicles entering the park, and greatly improving the flexibility of use";

[0004] Although the above scheme restricts vehicles entering and leaving the park by setting the height of the restriction pole, the height of the restriction pole lacks the function of automatic adjustment. In case of emergency, if vehicles need to pass, they have to move the entire device away, which undoubtedly increases the complexity and inconvenience of operation. In addition, conventional vehicle restriction devices often lack eye-catching signs, making them look more like ordinary facilities rather than important tools with clear management intentions. Such a design may cause drivers to ignore or despise the traffic management regulations of the park, thereby weakening the actual effect of traffic management and posing a potential threat to the traffic order and safety of the park. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a park vehicle restriction device, which has the characteristics of being able to restrict and release vehicles through a folding mechanism and being able to display park announcements or advertisements through a display cloth.
