Teaching laboratory numerical control distribution box

Abstract

The invention relates to the technical field of distribution boxes, in particular to a teaching laboratory numerical control distribution box, and the box comprises a box body and a numerical controlpanel installed on the box body; a fan is arranged at the bottom of the box body; the box body comprises side plates; wire pipes are arranged on the side faces of the box body; round holes are formedin the side plates; the wire pipes are connected to the round holes, and discharge outlets are formed in the side plates. Mounting plates are symmetrically arranged at an opening of the box body, threaded holes are formed in the mounting plates, bolt grooves are formed in the numerical control panel, bolts are arranged in the bolt grooves, the bolts are in threaded connection with the threaded holes, sealing interlayers are arranged in the side plates, sealing plates are arranged in the sealing interlayers, locking holes are formed in the sealing plates, locking rods are arranged in the locking holes, and through holes are formed in the side plates; and the locking rods pass through the locking holes. According to the structural design, a trigger type sealing structure is provided, a cooling function is provided for the distribution box before triggering, the working environment temperature of electrical elements is maintained, and the fault probability of the electrical elements is reduced.

Description

technical field [0001] The invention relates to the technical field of distribution boxes, in particular to a digitally controlled distribution box for teaching laboratories. Background technique [0002] Power distribution box is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, forms low-voltage distribution box. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. Cut off the circuit or alarm with the help of protective electrical appliances in case of failure or abnormal operation. Various parameters in operation can be displayed by means of measuring instruments, and some electrical parameters can also be adjusted to prompt or send out signals for deviations from normal working conditions. Its common faults include faults caused by the influence of ambient temperature on low-voltage el...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a digital control distribution box for teaching laboratories, through the fan located at the bottom of the box and the exhaust hole on the side plate of the box, the electrical components in the box, such as circuit breakers, fuses, etc. The temperature is lowered, which solves the problem that the general distribution box with fire protection function has good sealing performance but poor heat dissipation effect, so that the electrical components in the distribution box can work more stably, and the trigger-type sealing structure is set to realize In case of an emergency, the distribution box can be quickly sealed to a certain degree to achieve a certain degree of sealing effect and prevent the problem from expanding. At the same time, a protective device and a portable slot are set up to prevent accidental touches and promptly after accidental touches. Remedy; to address the issues raised in the background art above
