Description

Distribution box for cinema projection equipment Technical Field The utility model relates to the technical field of distribution boxes, in particular to a distribution box for cinema projection equipment. Background In modern theatres, theatre projection devices are central to the overall viewing experience and involve numerous high-power electronic devices such as digital projectors, sound systems, light control devices, and the like. These devices require a stable power supply to ensure smooth performance of the presentation. The distribution box plays a key role in power distribution and protection as an important component of theatre projection equipment. Currently, the existing distribution boxes for theatre projection equipment are in use, rely on manual operation, and then adjust the equipment, which is time consuming and laborious, resulting in lower operating efficiency of the theatre equipment. Disclosure of utility model It is an object of the present utility model to provide a distribution box for theatre projection equipment that addresses the above-described problems. The utility model realizes the above purpose through the following technical scheme: a cabinet for a theatre projection device, comprising: The door plate (1) and the box body (2), the side end of the door plate (1) is rotationally connected with the side end of the box body (2), The outer surface of the door plate (1) is provided with a power button (3), a locking mechanism (4) and a plurality of functional buttons (5), The power button (3) is connected with a breaker (6) in the box body (2), The breaker (6) is connected with one end of a low-voltage power supply (7) in the box body (2), The other end of the low-voltage power supply (7) is connected with the first end of an alternating current contactor (8) in the box body (2), The second end of the alternating current contactor (8) is connected with the first end of a central control board (9) in the box body (2), the third end of the alternating current contactor (8) is connected with the corresponding function button (5), The second end of the central control board (9) is connected with a plurality of sensors arranged at the cinema, The third end of the central control board (9) is connected with one end of a connecting terminal (10) in the box body (2), The other end of the wiring terminal (10) is connected with cinema projection equipment. Further, the device also comprises a U-shaped wire harness plate (11), wherein a first side plate of the U-shaped wire harness plate (11) is positioned between the alternating current contactor (8) and the central control plate (9), and a second side plate of the U-shaped wire harness plate (11) is positioned between the central control plate (9) and the wiring terminal (10). Compared with the prior art, the utility model has the beneficial effects that through the arrangement of the central control board and the connection of the central control board with the sensors and the function buttons in the cinema, the centralized management and the automatic control of the equipment are realized, the operation efficiency of the cinema equipment is improved, the manual intervention is reduced, and the safety and the stability of the projection are improved; the power distribution box is provided with a power button and a function button, a user can conveniently control the switch of equipment, the operation is simple and convenient, the door plate and the box body of the power distribution box are rotationally connected, so that maintenance and overhaul are more convenient, maintenance personnel can easily access internal components, the power distribution box can effectively prevent the danger of a power system when faults occur through the integrated circuit breaker, a low-voltage power supply, an alternating-current contactor and other components, the safety of the system is improved, the design of the power button connected with the circuit breaker can rapidly cut off the power supply when emergency happens, the occurrence of power accidents is avoided, the power distribution box comprises a plurality of function buttons, sensor interfaces and wiring terminals, the different connection requirements of cinema projection equipment are supported, the cinema projection equipment of different types can be adapted, the subsequent expansion or equipment replacement is convenient, the central control board can realize intelligent control on the electrical equipment of the cinema through the interaction of the sensors and the equipment, better viewing environment and equipment management are provided for the cinema, the cooperation of the low-voltage power supply and the alternating-current contactor in the power distribution box and the function button can effectively manage the power consumption, the power consumption is prevented from being unnecessarily increased, the stable operation cost is reduced, the stable operation of the equipment is pre
