Abstract
The utility model discloses a kind of buoyancy demonstrating device, comprise cross bar one, weight beam, rule, weight, knob two, groove, knob three, cross bar two, support; Described support is fixed on base, described cross bar two-way is crossed knob three and is fixed on support, and the upper end of described support arranges groove, and cross bar one moves up and down on groove by knob two, described weight beam is suspended on the front end of cross bar one, and described weight beam plays weight; The front end of described cross bar two arranges rule, and described rule is in the degree of depth in water for measuring weight.The beneficial effects of the utility model are, in experimentation, laboratory technician carries out the measurement of pulling force without the need to portable weight beam, the position of adjusting knob two pairs of weight beams is only needed to be fixed, ensure that weight is the reading carried out in the stationary case, be provided with rule at the middle part of the support of this device simultaneously, the measurement of counterweight object location can be realized.
Description
Technical field
The utility model relates to a kind of physics facility, especially a kind of buoyancy demonstrating device.
Background technology
At present, in physical experiment course in universities, buoyancy is the emphasis of education experiment, generally only have teacher to explain, student can not get getting information about, in existing experimentation to this concept of buoyancy, student's employing weight beam plays weight in the water of different depth, read weight beam, then according to balance between two forces principle, obtain the buoyancy suffered by weight.In the above process, student needs portable weight beam to carry out reading, and during reading, spring cannot ensure static, and reading will be inaccurate, and the height of equipment to weight also not recording height in test is measured.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of buoyancy demonstrating device.
For achieving the above object, the utility model adopts following technical proposals:
A kind of buoyancy demonstrating device, comprises cross bar one, weight beam, rule, weight, knob two, groove, knob three, cross bar two, support;
Described support is fixed on base, described cross bar two-way is crossed knob three and is fixed on support, and the upper end of described support arranges groove, and cross bar one moves up and down on groove by knob two, described weight beam is suspended on the front end of cross bar one, and described weight beam plays weight;
The front end of described cross bar two arranges rule, and described rule is in the degree of depth in water for measuring weight.
Further, buoyancy demonstrating device also comprises knob one, and described knob one is arranged on the middle part of cross bar one, for controlling the flexible of cross bar one;
Further, buoyancy demonstrating device also comprises knob four, and described knob four is arranged on the middle part of cross bar two, for controlling the flexible of cross bar two;
Further, the zero graduation value of described rule is positioned at below.
Further, described knob three can control the vertical height of cross bar two, for regulating the vertical height of rule.
The beneficial effects of the utility model are, in experimentation, laboratory technician carries out the measurement of pulling force without the need to portable weight beam, the position of adjusting knob two pairs of weight beams is only needed to be fixed, ensure that weight is the reading carried out in the stationary case, be provided with rule at the middle part of the support of this device simultaneously, the measurement of counterweight object location can be realized.
Accompanying drawing explanation
Fig. 1 is the utility model structural drawing;
Wherein 1. cross bar one, 2. weight beam, 3. rule, 4. weights, 5. knob one, 6. knob two, 7. groove, 8. knob three, 9. knob four, 10. cross bar two, 11. supports.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
A kind of buoyancy demonstrating device, comprises cross bar 1, weight beam 2, rule 3, weight 4, knob 26, groove 7, knob 38, cross bar 2 10, support 11;
Described support 11 is fixed on base, described cross bar 2 10 is fixed on support by knob 38, the upper end of described support 11 arranges groove 7, cross bar 1 moves up and down on groove by knob 26, described weight beam 2 is suspended on the front end of cross bar 1, and described weight beam 2 plays weight 4;
The front end of described cross bar 2 10 arranges rule 3, and described rule 3 is in the degree of depth in water for measuring weight 4.
Further, buoyancy demonstrating device also comprises knob 1, and described knob 1 is arranged on the middle part of cross bar 1, for controlling the flexible of cross bar 1;
Further, buoyancy demonstrating device also comprises knob 49, and described knob 49 is arranged on the middle part of cross bar 2 10, for controlling the flexible of cross bar 2 10;
Further, the zero graduation value of described rule 3 is positioned at below.
Further, described knob 38 can control the vertical height of cross bar 2 10, for regulating the vertical height of rule 3.
The beneficial effects of the utility model are, in experimentation, laboratory technician carries out the measurement of pulling force without the need to portable weight beam, the position of adjusting knob two pairs of weight beams is only needed to be fixed, ensure that weight is the reading carried out in the stationary case, be provided with rule at the middle part of the support of this device simultaneously, the measurement of counterweight object location can be realized.
By reference to the accompanying drawings embodiment of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
