Description

Technical Field

[0001] This utility model relates to the field of door edge protection, and in particular to a door-pinch prevention device. Background Technology

[0002] When a door closes, the hinged edge of the door panel and door frame closes. If fingers are placed in this gap, they can get caught. Current patents addressing this issue include a device disclosed in patent document CN201100085Y, which uses a rubber strip at the door seam to prevent hands from getting caught. However, this solution has some practical problems. A gap still exists between the rubber strip and the hinged edge of the door frame, and this gap widens over time (as the rubber strip loses elasticity and cannot return to its original position), causing the gap to reappear and potentially trap fingers. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an anti-hand-pinch device that prevents a person's hand from reaching into the gap between the hinged side frame of the door panel and the door frame, effectively preventing hands from being pinched when closing the door, and there is no problem of the gap being exposed even after long-term use.
