[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0019] Referring to the accompanying drawings, a novel elevator safety control box is shown, which includes a control box body 100, a plurality of control switches 200 and a control circuit board 300.

[0020] The control box body 100 is formed by enclosing a front box plate 110, an upper box plate 120, a lower box plate 130, a left box plate 140 and a right box plate 150. An upper mounting panel 160 extending upward and perpendicular to the upper box plate 120 is formed at the rear side edge of the upper box plate 120, and a card slot and a screw hole are provided on the upper mounting panel 160. A lower mounting panel 170 extending downward and perpendicular to the lower box plate 130 is formed at the rear side edge of the lower box plate 130, and a card slot is provided on the lower mounting panel 170. The upper mounting panel 160 and the lower mounting panel 170 are fixed at a designated position by means of card connection or screw fixing, so that the new elevator safety control box is installed and fixed.

[0021] A plurality of operating switches 200 are arranged at intervals on the front box plate 110 of the operating box body 100, and the plurality of operating switches 200 include four button switches 210, a rocker switch 220, an emergency stop switch 230, three knob switches 240, and a key switch 250. Among them, the button switch 210 preferably adopts an AK-1-P type button switch, which can be an up button switch, a down button switch, or a stop button switch, which can effectively control the up, down, and stop actions of the elevator, so that maintenance personnel can more conveniently perform maintenance on the elevator. The rocker switch 220 is a car lighting switch, which can control the lighting equipment in the elevator car. The emergency stop switch 230 is an emergency stop switch, which can control the emergency stop of the elevator car in special circumstances. The knob switch 240 can be a switch for emergency electric, emergency brake, shaft lighting, etc., which can effectively switch the operating state of the elevator. The key switch 250 is a main power switch, which controls the main power of the elevator to be disconnected by a key to improve safety.

[0022] The operating circuit board 300 is arranged in the operating box body 100. Each operating switch 200 is connected to the operating circuit board 300 through a printed board connector 201, and the printed board connector 201 corresponding to each operating switch 200 is integrated on the operating circuit 300. The utility model connects the operating switch 200 to the operating circuit board 300 through a quick connector 201, replacing the traditional wiring harness wiring method. Through the integrated printed board design, a large amount of wiring harness and assembly time are reduced, and possible errors caused by workers in wiring are avoided, which effectively reduces costs and improves product quality; at the same time, the utility model adopts a streamlined design, reduces the overall volume, and is more convenient for transportation and installation.

[0023] The new elevator safety control box of the utility model also includes a bypass device 400, which is installed on the front box plate 110 of the control box body 100. The bypass device can effectively prevent maintenance personnel from being unfamiliar with the terminals in the control cabinet and causing short-circuit errors, other safety hazards, and even worse, directly burning out the circuit board and other irreversible accidents.
