Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, and more specifically, to an adjustable tooling applicable to the installation of the bent section of an apron board. Background Art

[0002] The escalator apron board is the enclosing board part adjacent to both sides of the steps, pedals or tapes, which plays the functions of protecting passengers' safety and beautifying the appearance. The apron board mainly consists of a panel, a reinforcing rib, a connecting plate between the apron boards, and a fixing plate between the apron board and the truss.

[0003] A brush board is installed on the apron board, and the brush board is connected to the apron board by bolts. When the apron board is in use, since the brush board is not easy to disassemble and assemble, the working burden is increased when replacing the brush board. At the same time, there is a problem of pinching feet when the apron board is in use. In the existing patent, a structure of an escalator apron board, with the patent authorization number CN216377119U, by setting an apron board, a slot and an elastic group, the gap between the apron board and the escalator step is increased. At the same time, when the elastic group elastically presses the foot, it is convenient for the user to pull out the foot; through the design of the fixing mechanism, it is convenient to tightly install the brush board, improving the use stability of the brush board and bringing convenience to the disassembly and assembly of the brush board.

[0004] During the installation of the existing bent section of the apron board, it needs to be installed in cooperation with tooling fixtures. However, there are two kinds of bending angles of 30° and 35° for the bent section of the apron board. Therefore, two kinds of tooling fixtures are required to position different apron boards, which increases the installation cost to a certain extent. In order to enable a set of tooling to install apron boards with different bending angles, we propose an adjustable tooling applicable to the installation of the bent section of the apron board to solve the above problems.
