Embodiment Construction

[0011] The specific technical content of the present invention will be further described below in conjunction with the accompanying drawings. Combined with the above-mentioned apron board anti-pinch device, for the T-shaped hole space of the anti-pinch strip hardware part (2), the small opening size of the open T-shaped hole space is 4 mm to 11 mm; the size of the large hole space is 8 mm to 18 mm; The large hole size of T-shaped hole should satisfy the T-shaped head of T-shaped head bolt (6) and put into; Its small opening size should satisfy that T-shaped head bolt can stretch out the small opening. Its T-shaped head bolt (6) is usually M3~M10, wherein M6 is the most commonly used. In the above-mentioned apron plate anti-pinch device, the T-shaped hole space (7) in the anti-pinch strip hard part (2) is a T-shaped through hole formed by one-time extrusion; the color of the hard part (2) can be any color . The best embodiment of this anti-pinch bar is: its shape can be pagod...

Description

technical field [0001] The invention relates to an anti-pinch device suitable for an escalator apron board. Background technique [0002] Escalators have been widely used in large public places such as shopping malls, subways, and airports because of their high efficiency in transporting a large number of people. Therefore, their safety is particularly important. The national standard stipulates the gap between the steps of the escalator and the apron board, and requires that the possibility of stagnation between the steps and the apron board should be reduced, and an anti-pinch device can also be added to solve the problem. The brush anti-pinch device has been used at home and abroad. It was first adopted in Britain and the United States. The brush anti-pinch device is composed of a base made of aluminum alloy and a brush. It is installed on the apron plates on both sides of the escalator to cover the operation. The gap between the steps and the apron boards, so that the a...
