Description
Technical Field
The utility model relates to a teaching aid technical field, specifically speaking relates to a portable laboratory glassware show shelf.
Background
In the physical and biological teaching process, some physical instruments and biological models are often needed to be used, and the teaching effect is improved through visual display. Currently, the display of laboratory instruments or biological models usually adopts two ways: firstly, a teacher holds a physical instrument or a biological model for display, and the display mode increases the burden of the teacher; and secondly, students can watch around the experimental instrument or the biological model, and the display mode is not beneficial to the peripheral students to clearly see the structure of the experimental instrument or the biological model because of more students.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a portable laboratory glassware show shelf, technical problem more than solving.
In order to solve the above problems, the utility model adopts the following technical scheme:
a portable experimental instrument display stand comprises a base, a base fixing device, a rotating shaft vertically assembled on the base and a display stand main body assembled at the top of the rotating shaft, wherein the display stand main body comprises a top plate, a bottom plate and a supporting column arranged between the top plate and the bottom plate; the bottom end of the rotating shaft is assembled in the middle of the base through a bearing embedded on the base, and the top end of the rotating shaft is fixedly assembled in the middle of the bottom plate; the base fixing device comprises a U-shaped fixing clamp and a jackscrew; the top support arm of the U-shaped fixing clamp transversely penetrates into a through hole formed in the base; the jackscrew is assembled on the bottom support arm of the U-shaped fixing clamp in a threaded manner, and a clamping plate is fixed at the top end of the jackscrew; the experimental instrument fixing device comprises a plurality of positioning threaded holes formed in the top surface of the bottom plate and at least four positioning bolts matched with the positioning threaded holes.
Preferably: the middle part of the top plate is provided with a lifting ring.
Preferably: and the upper part of the positioning bolt is wrapped with a soft protective sleeve.
Has the advantages that: compared with the prior art, the utility model liberates both hands of the teacher on one hand, and provides convenience for the teacher to operate the experimental instrument or explain the biological model; on the other hand, the displayed experimental instrument or biological model can rotate 360 degrees, so that students can see the structure of the experimental instrument or biological model clearly, and the teaching quality is improved.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic cross-sectional view of a-a in fig. 1.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
Examples
Referring to fig. 1-2, the portable experimental instrument show shelf of this embodiment includes base 1, perpendicular assembly pivot 2 on base 1 and the show shelf main part of assembly at pivot 2 top, for the stability of guaranteeing the show shelf, avoids teaching in-process show shelf to topple over be equipped with base fixing device on the base 1. The display stand body comprises a top plate 3, a bottom plate 4 and a support column 5 arranged between the top plate 3 and the bottom plate 4. Wherein:
the bottom end of the rotating shaft 2 is assembled in the middle of the base 1 through a bearing 6 embedded on the base 1, and the top end is fixedly assembled in the middle of the bottom plate 4.
The base fixing device comprises a U-shaped fixing clamp 7 and a jackscrew 8. The top support arm of the U-shaped fixing clamp 7 transversely penetrates into a through hole formed in the base 1. The jackscrew 8 is assembled on the bottom support arm of the U-shaped fixing clamp 7 in a threaded mode, and a clamping plate 9 is fixed to the top end of the jackscrew 8. During the teaching, put the show shelf to the table bench and be close to the edge, make the bottom support arm of U-shaped fixation clamp 7 and jackscrew 8 be located the bottom of table bench, operation jackscrew 8 makes the bottom surface of splint 9 top tight table bench, realizes the fixed between show shelf and the table bench.
A display space is formed between the top plate 3 and the bottom plate 4, and an experimental instrument fixing device is arranged in the display space and comprises a plurality of positioning threaded holes 10 formed in the top surface of the bottom plate 4 and at least four positioning bolts 11 matched with the positioning threaded holes 10. During teaching, the experimental apparatus or the biological model to be displayed is placed on the bottom plate 4, and the experimental apparatus or the biological model is fixed through the positioning bolt 11 and the positioning threaded hole 10. The showing stand can be rotated at will during the showing process so that students can see the structure of the shown experimental apparatus or biological model clearly.
To facilitate the transfer of the display shelf, a bail 12 is fitted in the middle of the top plate 3.
In order to avoid the surface of the experimental instrument or the biological model from being scratched by the direct contact of the positioning bolt 11 and the experimental instrument or the biological model, the upper part of the positioning bolt 11 is wrapped by a soft protective sleeve. The soft protective sleeve can be a layer of rubber injected on the upper part of the positioning bolt 11, and can also be soft cloth wound on the upper part of the positioning bolt 11.
The utility model has the advantages that on one hand, both hands of the teacher are liberated, and convenience is provided for the teacher to operate the experimental instrument or explain the biological model; on the other hand, the displayed experimental instrument or biological model can rotate 360 degrees, so that students can see the structure of the experimental instrument or biological model clearly, and the teaching quality is improved.
The above is only the embodiment of the present invention, not so limit on the other hand through the patent scope of the present invention, all utilize the equivalent structure made in the specification and the attached drawings, directly or indirectly apply to other related technical fields, all with the same principle within the patent protection scope of the present invention.
