Anti-winding device for itineration host swing door

Abstract

The invention relates to an anti-winding device for an itineration host swing door. The anti-winding device comprises a movable door plate (1), wherein a protective bushing (8), a nut plate (7), a pressure plate (9) and a hinge base (6) are respectively arranged at the outer side of the movable door plate (1); the two ends of the protective bushing (8) are respectively embedded between the nut plate (7) and the movable door plate (1) and between the pressure plate (9) and the movable door plate (1); a hinge is connected to the hinge base (6); a spacer bush (5) is arranged between the protective bushing (8) and the movable door plate (1); a pin roll (4) is arranged inside the spacer bush (5); and a left torsional spring (2) and a right torsional spring (3) are respectively arranged on the left and right ends of the pin roll (4). The anti-winding device for the itineration host swing door solves a problem that the spring is caught and tangled by fibre, so that the swing door is normally opened and closed, thereby avoiding a phenomenon that the fibre is caught by and tangled with the itineration host.

Description

Technical field [0001] The invention relates to an anti-wrapping device for a spring door of a touring host. Background technique [0002] The original spring door of the touring host has the problem that the spring is easy to be entangled by the fiber, which causes the spring door to be stuck, so that the spring door cannot be opened and closed in place, or the entangled fibers line up in bundles and are not sucked away. It is hung on the tour host, which not only increases the difficulty of cleaning the tour host, but also affects the normal operation of the tour cleaner. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide an anti-wrapping device for the spring door of a touring host that can prevent the spring from being easily wound by fibers. [0004] The purpose of the present invention is achieved as follows: [0005] An anti-wrapping device for a spring door of a touring host, comprising a shutter...
