Teacher demonstration bench in physical laboratory

Abstract

The invention discloses a teacher demonstration bench in a physical laboratory, the opening of several U-shaped supports orientates to the inner side of the demonstration bench, adjacent two U-shaped supports at will are passed through more than two upper cross beams and are connected to a frame of the experiment table in order, a table surface is fixed on a frame of the demonstration bench, a hollow apparatus cabinet inserts from the front end of the frame of the demonstration bench, a backboard is fixed at the rear end of the frame of the demonstration bench, the frame of the demonstration bench between the hollow apparatus cabinet and the backboard forms an electrical installation channel, and a control table is arranged on the table surface and is connected to the power supply in the electrical installation channel. The teacher demonstration bench can realize the separation of the electrical installation channel and the hollow apparatus cabinet, the exposure of the wire outside the demonstration bench can be avoided, and the external beauty of the demonstration bench can be realized; the backboard is hinged to the upper cross beam simultaneously, so that the convenience for electrical installation, electrical heat radiation and electrical maintenance are realized.

Description

technical field [0001] The invention relates to the technical field of laboratory furniture, in particular to a demonstration table for teachers in a physics laboratory. Background technique [0002] The teacher's demonstration table in the physics laboratory is a kind of experimental furniture that is convenient for teachers to describe physics experiments. At present, the teacher's demonstration table in the physics laboratory is mostly wood structure, steel frame structure, or steel-wood structure, which is not resistant to acid and alkali, easy to leak electricity, not waterproof, and not fireproof. Only a layer of rubber mat is used on the teacher's demonstration table To make a countertop, the teacher must demonstrate according to a set of strict and cumbersome operating procedures. In addition, the installation of instruments is essential in the demonstration of physical experiments, and the exposed wires are installed on the back of the instrument cabinet. Although ...

Problems solved by technology

At present, the teacher's demonstration table in the physics laboratory is mostly wood structure, steel frame structure, or steel-wood structure, which is not resistant to acid and alkali, easy to leak electricity, not waterproof, and not fireproof. Only a layer of rubber mat is used on the teacher's demonstration table As a countertop, the teacher must follow a set of strict and cumbersome operating procedures to demonstrate

In addition, the installation of instruments is essential in the demonstration of physical experiments, and the exposed wires are installed on the back of the instrument cabinet. Although the instrument installation and electrical maintenance are convenient, it affects the beauty of the teacher's demonstration table
