An improvement to the above technical solution is: in order to accurately limit the position of the experimental display stand when it is erected, a limit inclined block is provided on the short connecting rod.

An improvement to the above technical solution is that: in order to limit the position of the experimental display platform when it is placed flat, buckles are provided on the edge of the upper cover.

A further improvement to the above technical solution is that: for the convenience of carrying, a handle is respectively provided on the lower cover and the upper cover.

Instructions:

When in use, the experimental display stand is supported by adjusting the angle of the long and short connecting rods to form a horizontal or vertical display plane, and the magnetic suction seat is adsorbed at the corresponding scale position of the display stand, and then the experimental equipment is passed through the screw. Fix it on the magnetic suction seat at the corresponding position, and you can carry out the experiment display; you can also install the power supply at the bottom of the upper cover, and if necessary, plug the power supply wire into the power supply under the experimental display stand to turn on the power. After the experiment is over, the connecting rod drives the experimental display stand to be folded in the upper cover and locked with buckles, then the experimental equipment is classified and stored in the partition of the lower cover, and finally the upper cover and the lower cover are closed and locked.

Beneficial effect:

In the utility model, a display platform is provided in the inner cavity of the upper cover to provide a platform for the demonstration of the experiment in the classroom; at the same time, a partition is arranged in the inner cavity of the lower cover to divide it into multiple areas for storing different experimental equipment. The experiment box is convenient to carry, easy to operate and low in cost.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figures 1 and 2, a teaching experiment box includes an upper cover 1 and a lower cover 2, and the upper cover 1 and the lower cover 2 are connected together through a hinge 3; A long connecting rod 5 and a short connecting rod 6 are connected with an experiment display stand 4, and one end of the long connecting rod 5 and the short connecting rod 6 is respectively connected with the connecting rod support 7 welded at the bottom of the cavity of the upper cover 1, and the long connecting rod The other ends of the connecting rod 5 and the short connecting rod 6 are respectively fixed on the front end of the experimental display stand 4 by a female nail, and the experimental display stand can be placed flat or erected by adjusting the angle of the two connecting rods; in order to improve the stability of the experiment The same long connecting rod and a short connecting rod are fixed at the rear end of the experimental display stand 4 corresponding to its front end. The method is the same; for the convenience of positioning, a steel plate is coated on the outside of the experimental display stand 4, and a scale is provided on the front of the steel plate; two vertically intersecting partitions 8 are installed in the inner cavity of the lower cover 2, and the inner cavity of the lower cover 2 is separated by the partition. The cavity is divided into four different storage areas, so that different experimental equipment 13 can be classified and placed, and a magnetic suction seat 12 is placed in one of the storage areas, so that the experimental equipment 13 can be adsorbed on the experimental display stand 4 conveniently.

In order to accurately limit the experimental display stand 4 when it is erected, a limit inclined block is fixed on the short connecting rod 6, and when the experimental display stand 4 is erected, the position is limited by the limit inclined block on the short connecting rod 6 , keeping it vertical.

As shown in Figure 2, in order to limit the position of the experimental display stand 4 when it is placed flat, a buckle 9 is provided on the edge of the upper cover 1 to prevent the experimental display stand from opening due to its own weight when the test box is lifted.

As shown in FIG. 1 and FIG. 2 , for the convenience of carrying, a handle 10 is respectively installed on the upper cover 1 and the lower cover 2 .

When in use, adjust the angles of the long and short connecting rods to make the experimental display stand flat or upright; when laying flat, the bottom edge of the experimental display stand is stuck in contact with the side wall of the upper cover, and it can be displayed in a plane, and There is a certain gap between the experimental display stand and the bottom of the upper cover, which is used to place the power supply 11 (as shown in Figure 1); Straight state. The lower cover partition constitutes the article storage area of the experiment box, and is used for storing magnetic suction seats and experiment equipment.

When the experiment is displayed, the experimental equipment is fixed on the magnetic suction base by screws, and the positioning of the experimental equipment on the experimental display stand can be realized through the switch on the magnetic suction base. After the experiment is over, the buckle on the upper cover can be used to fix the experiment display stand, and then it can be closed and taken away.

The experiment box is not limited to installing two vertically intersecting partitions at the bottom of the cavity of the lower cover, and multiple partitions can be arranged in combination to divide different sections according to needs.

In the utility model, a display platform is provided in the inner cavity of the upper cover to provide a platform for the demonstration of the experiment in the classroom; at the same time, a partition is arranged in the inner cavity of the lower cover to divide it into multiple areas for storing different experimental equipment.
