Abstract
The utility model discloses a liquid level tension testing device used for science popularization. The liquid level tension testing device comprises a bracket with the bottom being connected with a supporting seat, wherein a gear which is mutually rotatably connected with a manual adjusting button is arranged at the upper part of the bracket; the gear is in mutual transmission connection with a slide rack at the top of the bracket; the rack is in sliding connection with a slide sleeve which is fixedly connected with the bracket; the bracket is fixedly provided with a dividing ruler; a fixed frame with a spring is arranged at the top of the dividing ruler; the bottom end of the spring is connected with a connection rod with a scale pointer; the connection rod penetrates through a limiting ring at the bottom end of the dividing ruler and is mutually clamped with a tension testing piece through a clamp; and the supporting seat is provided with a solution container which mutually corresponds to the tension testing piece up and down. According to the liquid level tension testing device used for the science popularization, the technical problems in the prior art that the testing equipment is complicated, the manufacture cost is high, the test results of testing equipment cannot be seen directly, the testing equipment is not suitable for science popularization and application, and the operation process needs more time and labor are solved.
Description
Technical field
The utility model belongs to the device for testing tensile force technical field of scientific popularization teaching use, is specifically related to the liquid level device for testing tensile force that a kind of scientific popularization is used.
Background technology
Because liquid has capillary characteristic, therefore some insects can floating stop on liquid level, although this phenomenon can detect by an unaided eye out, the liquid level tension test equipment using in the popularization of scientific popularization, complex structure, cost are high, not directly perceived, and testing procedure is loaded down with trivial details, and when the liquid of different densities is tested, operating process is wasted time and energy, being not suitable for scientific popularization applies
Summary of the invention
The purpose of this utility model is to solve prior art to have the technical matters that testing apparatus is complicated, cost is high, not directly perceived, operating process is wasted time and energy, and the liquid level device for testing tensile force that provides a kind of scientific popularization to use, to overcome the deficiencies in the prior art.
To achieve these goals, the liquid level device for testing tensile force that a kind of scientific popularization of the utility model is used, its main points are that it comprises the support that bottom is connected with supporting seat; The top of described support is provided with the gear being mutually rotationally connected with manual adjustments button; Prop up top of the trellis and be provided with the tooth bar meshing with described gear; Described tooth bar is slidably connected by the sliding sleeve being mutually permanently connected with support; Before described tooth bar, be provided with rule; The top of described rule is provided with the fixed mount with spring; The bottom of described spring is connected with the connecting rod with tuning drive gear; Described connecting rod is through the spacing ring of rule bottom and by clamp and the mutual clamping of tension test sheet; Described supporting seat is provided with and the mutual upper and lower corresponding solution vessel of tension test sheet.
In order to test the Tensity size of same liquid in equal area difformity vessel, described tension test sheet is square or triangle.
The utility model reasonable in design, easy to use, because tension test sheet is connected with spring by clamp, connecting rod, and connecting rod is provided with tuning drive gear, when rotary manual adjusting knob, tooth bar can slide up and down by the drive of gear, thereby drive rule to slide up and down, tension test sheet can move up while being subject to pulling force upwards gradually, when tension test sheet and liquid level depart from completely, tuning drive gear scale pointed is the tension force of liquid level, and operating process is easy, directly perceived and cost is low.The utility model solved that prior art testing apparatus is complicated, cost is high, directly perceived, be not suitable for the technical matters that scientific popularization is applied and operating process is wasted time and energy.
Accompanying drawing explanation
Accompanying drawing is the utility model structural representation.
In figure 1, support 2, supporting seat 3, manual adjustments button 4, sliding sleeve 5, tooth bar 6, rule 7, fixed mount 8, spring 9, tuning drive gear 10, connecting rod 11, spacing ring 12, clamp 13, tension test sheet 14, solution vessel
Embodiment
With reference to accompanying drawing, a kind of liquid level device for testing tensile force of the utility model, it comprises the support 1 that bottom is connected with supporting seat 2; The top of described support 1 is provided with the gear being mutually rotationally connected with manual adjustments button 3; Prop up top of the trellis and be provided with the tooth bar 5 meshing with described gear; Described tooth bar 5 is slidably connected by the sliding sleeve 4 being mutually permanently connected with support; On described tooth bar 5, be fixed with rule 6; The top of described rule 6 is provided with the fixed mount 7 with spring 8; The bottom of described spring 8 is connected with the connecting rod 10 with tuning drive gear 9; Described connecting rod 10 is through the spacing ring 11 of rule 6 bottoms and by clamp 12 and the mutual clamping of tension test sheet 13; Described supporting seat 2 is provided with and the mutual upper and lower corresponding solution vessel 14 of tension test sheet 13; Described tension test sheet 13 is square or triangle.
Principle of work: before use, solution is put into solution vessel 14 corresponding Shang Xia 13 with tension test sheet, rotation manual adjusting knob 3 makes tension test sheet 13 just in time be placed on liquid level, rotation manual adjusting knob 3 gently now, rule 6 is slowly moved up, because tension test sheet 13 is by clamp 12, connecting rod 10 is connected with spring 8, the capillary impact of liquid body, tension test sheet 13 can not be separated from each other with liquid level at once, but spring 8 elongation gradually, when manual adjustments button 3 rotates extremely certain angle, tension test sheet 13 can be completely separated with liquid level, now, the scale of tuning drive gear 9 indications is the Tensity size of liquid level, to the difform tension test sheet of same area, can change, so that test is carried out differentiating measurement to the difform Tensity size of same solution.
Of the present utility model simple in structure, easy to operate, more directly perceived while particularly student being carried out to teaching demonstration, operating process is also easily understood.
