Description
Technical field
The utility model relates to teaching device design technical field, particularly relates to the special soil property test box of a kind of bioconversion medium.
Background technology
The development of China's Modern Education Technology originates in 1920's, is referred to as audio-visual education programme.The media such as the magic lantern used in audio-visual education programme activity at that time, film than original knowledge from hearsay and print media afterwards for teaching, its circulation way has been leaped major step, belong to the category of Modern Education Technology, but this is not also the Modern Education Technology in complete meaning, the primary stage of just Modern Education Technology development.Electronic instruction equipment is that modern education educates indispensable device concept with Modern Education Technology such as computing machine, projector, magic lantern, recording, video recording, broadcast, film, TV, computing machines, use Modern Educational Theory and technology, by the design to teaching process and resource, exploitation, application, management and evaluation, to realize the theory and practice of teaching modernization.But, the special soil property test box of bioconversion medium on existing market lacks and contributes to realizing the movement of Mobile base and the device of fixed function, the bioconversion medium special soil property test box also had lacks the device that the weight not only contributing to the spacing of resilient sleeve but also contribute to casing carrys out the elastic force of adjustable elastic cover, the demand of actual conditions can not be met.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides the special soil property test box of a kind of bioconversion medium.
The utility model is achieved through the following technical solutions:
The special soil property test box of a kind of bioconversion medium, comprise Mobile base, the both sides of described Mobile base are provided with lug, and described lug is provided with screw rod, and the lower end of described screw rod is provided with movable pulley, the middle part of Mobile base is provided with stud, described stud is provided with setting nut, described setting nut is provided with resilient sleeve, the upper end of described stud is provided with casing, the lower end of described casing is arranged with L shaped plate, and the upper end of stud is fixed with limited block by screw.
As optimal technical scheme of the present utility model, described limited block is positioned at the lower end of casing, and the lower end of described screw rod is provided with positive stop lug boss, and the upper end of screw rod is provided with knob.
As optimal technical scheme of the present utility model, described lug has four, and the symmetrical both sides being arranged on Mobile base.
As optimal technical scheme of the present utility model, described L shaped plate has two at least, and is evenly distributed on casing.
During onsite application, operating personnel need Mobile base to be placed on correct position according to actual conditions, then are arranged in casing by testing element, can carry out the test job of bioconversion medium soil property.
Compared with prior art, the beneficial effects of the utility model are: the utility model contributes to by the screw rod being provided with movable pulley the movement and the fixed function that realize Mobile base, the spacing of resilient sleeve is contributed on the one hand by the stud being provided with setting nut, resilient sleeve and limited block, the weight also contributing to casing on the other hand carrys out the elastic force of adjustable elastic cover, and structure is simple, easy to operate, economical and practical.
