Detailed Description

The invention is described in detail below with reference to the figures and examples. The following experimental examples and examples are intended to further illustrate but not limit the invention.

Referring to fig. 1, the present invention provides a teaching experimental device accommodating box 100, where the teaching experimental device accommodating box 100 includes a base 10, an upper cover 20 assembled with the base 10 to form a circular accommodating space, a rotating shaft 30 disposed in the accommodating space and fixedly connected to the base 10, a rotating support assembly 40 fixedly disposed on the rotating shaft 30, and a plurality of experimental device accommodating boxes 50 detachably connected to the rotating support assembly 40.

The base 10 includes a bottom plate 11, a side plate 12 formed by vertically bending and extending from the bottom plate 11 to a direction close to the upper cover 20, and a support ring 13 extending from the side plate 12 to a direction close to the rotating shaft 30.

The rotating shaft 30 includes a shaft portion 31 and a plurality of engaging grooves 32 formed by being recessed from one end of the shaft portion 31 in a circumferential direction toward an axial direction. One end of the shaft portion 31, which is provided with the locking groove 32, is embedded in the base 10.

Preferably, the plurality of locking grooves 32 are uniformly arranged along the circumferential direction of the shaft body 31. Through shaft part 31 sets up draw-in groove 32 has strengthened pivot 30 with joint strength between the base 10 has promoted pivot 30's structural stability, simultaneously, makes experimental device containing box 100 is used in teaching's stability of falling stronger, and life is longer.

The rotating support assembly 40 includes a fixing ring 41 fixedly disposed at one end of the rotating shaft 30 close to the base 10 along the circumferential direction of the rotating shaft 30 and a plurality of support bars 42 movably connected to the fixing ring 41.

The fixing ring 41 includes a main body 411 having a hollow cylindrical cross section, a sliding groove 412 formed by recessing from the main body 411 in the circumferential direction away from the end of the upper cover 20 in the axial direction, and a plurality of fixing grooves (not shown) parallel to the axial line and communicating with the sliding groove 412. A buckle (not shown) is disposed at an end of the fixing groove far from the sliding groove 412, and in the recovery state of the support bar 42, the support bar 42 is fixed in the fixing groove by the buckle.

Preferably, in the present embodiment, the fixing ring 41 is spaced apart from the base 10, so as to further enhance the falling performance of the experimental device accommodating box 100 for teaching. Meanwhile, in the present embodiment, the claim book fixing ring 41 is integrally formed with the rotation shaft 30.

Preferably, in order to maintain the stability of the supporting bar 42 under flat loading, in the present embodiment, the surface of the sliding groove 412 close to the bottom plate 11 is arranged to be in the same plane with the surface of the supporting ring table 13 far from the bottom plate 11.

So set up for adjacent mutual repulsion between the support bar 42, and then no matter how many of the teacher selected the equipment, can keep adjacent all the time the interval between the experimental facilities holding box 50 equals, maintains the focus of teaching experimental facilities holding box 100, the reliability is stronger.

For example, when a teacher selects two kinds of experimental devices, in the process of loading the experimental devices, the teacher needs to level the two support bars 42, the two support bars 42 are separated from each other under the action of the first permanent magnet 422, and finally an included angle of 180 ° is formed, and after the two experimental device accommodating boxes 50 are placed in the accommodating space, the center of the experimental device accommodating box 100 for teaching is kept stable; when a teacher selects three experimental devices, in the loading process of the experimental devices, the teacher needs to level three support bars 42, the three support bars 42 are far away from each other under the action of the first permanent magnet 422, and finally form an included angle of 120 degrees, and when the three experimental device accommodating boxes 50 are placed in the accommodating space, the center of the experimental device accommodating box 100 for teaching is kept stable.

The bottom wall of the experimental device accommodation box 50 is provided with a third permanent magnet 51 attracted to the second permanent magnet 423. When a teacher puts the experimental equipment into the experimental equipment containing box 50 and puts the experimental equipment containing box 50 into the containing space, the third permanent magnet 51 attracts the second permanent magnet to each other to detachably connect the experimental equipment containing box 50 and the support bars 42. Through adopting the connection mode of dismantling of magnetism to inhale, simplified the internal structure of experimental device containing box 100 for teaching uses very conveniently simultaneously.

Compared with the prior art, the experimental equipment containing box for teaching provided by the invention has the advantages that the rotating shaft fixedly connected with the base and the rotating support component fixedly arranged on the rotating shaft are arranged in the containing space, a teacher can configure the experimental equipment containing box according to experimental equipment needed before class, only needed equipment is put into the containing space, meanwhile, after the teacher puts the equipment into the experimental equipment containing box, the experimental equipment containing box is detachably connected with the supporting bars through the mutual attraction between the third permanent magnet and the second permanent magnet, the magnetic poles of the first permanent magnets between the adjacent supporting bars are the same, the adjacent supporting bars are mutually repelled, and the distance between the adjacent experimental equipment containing boxes can be always kept equal no matter how many equipment the teacher selects, the gravity center of the experimental device containing box for teaching is maintained, and the reliability is higher.
