Description
Technical field
Chemistry teaching technical field is the utility model is related to, specially a kind of chemistry teaching test tube clamp.
Background technology
At present, during chemistry teaching, test tube can be used unavoidably, and matching used test tube clamp be also must can not
It is few, and present test tube clamp is all intended for single use, and can clamp one group of test tube to the greatest extent every time, in the field of some a large amount of test tubes of needs
Institute, the time of work is so undoubtedly the increase in, influences job schedule.
The content of the invention
The purpose of this utility model is to provide a kind of chemistry teaching test tube clamp, to solve to propose in above-mentioned background technology
The problem of.
To achieve the above object, the utility model provides following technical scheme：A kind of chemistry teaching test tube clamp, including circle
Plate shape housing and the handlebar for being fixed on circular plate type case top center, multigroup hollow structure is provided with the circular plate type housing,
One group of gag lever post is fixed in the inside of the hollow structure, and the body of rod of the gag lever post is plugged on the interior of one group of movement touch panel one end
Portion, the other end of the mobile touch panel are provided with groove structure, and the circular plate type housing is positioned at mobile touch panel concave slot structure
Corresponding position is provided with another group of groove structure, and the gag lever post is between one end of hollow structure and the mobile touch panel
One group of helical spring is socketed on the body of rod.
Preferably, the extended line of the axis of multigroup hollow structure intersects with the center of circle line of the circular plate type housing.
Preferably, multigroup hollow structure is evenly distributed at the one of the circular plate type housing on circularity line so that
Test tube after clamping can increase the gravity being subject to uniform.
Preferably, the construction profile of the cross section of the gag lever post is square so that mobile touch panel can be normal
Transverse shifting, but not situation about rotating.
Preferably, the radius of the groove structure is identical with the structure radius of test tube, circular plate type housing and shifting are added
Dynamic contact area between touch panel and test tube so that being more uniformly stressed of test tube.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in construction, can clamp every time
Multigroup test tube, so as to accelerate the efficiency of work, in addition, the device clamps by the elastic force of helical spring to test tube, energy
Enough on the premise of test tube is not destroyed, test tube is effectively clamped.
Brief description of the drawings
Fig. 1 is a kind of structural representation of chemistry teaching test tube clamp of the utility model.
In figure：1. circular plate type housing, 2. handlebars, 3. hollow structures, 4. gag lever posts, 5. helical springs, 6. movement touch panels,
7. groove structure.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
A kind of referring to Fig. 1, embodiment provided by the utility model：A kind of chemistry teaching test tube clamp, including circular plate type
Housing 1 and the handlebar 2 for being fixed on the top center of circular plate type housing 1, multigroup hollow structure 3 is provided with the circular plate type housing 1,
One group of gag lever post 4 is fixed in the inside of the hollow structure 3, and the body of rod of the gag lever post 4 is plugged on one group of one end of movement touch panel 6
Inside, the other end of the mobile touch panel 6 are provided with groove structure 7, and the circular plate type housing 1 is positioned at the mobile further groove of touch panel 6
The corresponding position of structure 7 is provided with another group of groove structure 7, and the gag lever post 4 is positioned at one end of hollow structure 3 and the movement
One group of helical spring 5 is socketed on the body of rod between touch panel 6.
The extended line of the axis of multigroup hollow structure 3 intersects with the center of circle line of the circular plate type housing 1；It is multigroup described
Hollow structure 3 is evenly distributed at the one of the circular plate type housing 1 on circularity line so that test tube will can be subject to after clamping
Gravity increase is uniform；The construction profile of the cross section of the gag lever post 4 is square so that mobile touch panel 6 can be normally horizontal
To movement, but not situation about rotating；The radius of the groove structure 7 is identical with the structure radius of test tube, adds circle
Contact area between plate shape housing 1 and mobile touch panel 6 and test tube so that being more uniformly stressed of test tube.
Specifically used mode：In utility model works, the test tube that mobile touch panel 6 clamps needs, Ran Houhuan are first moved
Slow to loosen mobile touch panel 6, now, test tube can be carried out effective in the case where mobile touch panel 6 and groove structure 7 are for combination to test tube
Clamping, and now, helical spring 5 can clamp to test tube, test tube can be carried out on the premise of test tube is not destroyed
Effective clamping.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it can realize that this practicality is new in other specific forms
