Description
Technical field
The utility model relates to a kind of improvement of displacement and pressure measurement mechanism, particularly a kind of be applicable to impart knowledge to students be convenient to the displacement and pressure measurement mechanism observing and understand.
Background technology
In some occasion, we need to measure displacement and two parameters of pressure simultaneously, and for example the tire of Automobiles ' Safety Examination descends and dead weight capacity.In existing measurement mechanism, measuring displacement and pressure great majority separately carries out, be special displacement or special measuring pressure, the device of measuring displacement and pressure one is also arranged, come from similar jack hydraulic cylinder and the source that produces displacement and pressure has, they have certain pollution to environment, and the measuring system rate of exchange are complicated, and cost is high.On the other hand, for teaching, the experimental box that the unit of many production instruments used for education provides mostly has too many closure, is not easy to observation of students and understanding.
The utility model content
The utility model purpose be provide in order to overcome the deficiencies in the prior art a kind of be applicable to impart knowledge to students be convenient to the displacement and pressure measurement mechanism observing and understand.
For achieving the above object, the technical solution adopted in the utility model is: a kind of displacement and pressure measurement mechanism comprises fixed block, displacement transducer, slide block, guide rod, right fixed head, pressure transducer, left fixed head, fixed head; Described left fixed head, right fixed head parallel interval arrange; Be provided with screw mandrel between described left fixed head, right fixed head; The parallel screw mandrel of described guide rod is arranged between left fixed head, right fixed head; The end that described screw mandrel stretches out right fixed head is provided with runner; Described slide block is arranged on screw mandrel, and can be along the guide rod side-to-side movement; Be provided with spring on screw mandrel between described left fixed head and slide block; Be provided with spring on screw mandrel between described right fixed head and slide block; One end of described displacement transducer is connected with slide block, and the other end is fixed on fixed block; One end of described pressure transducer is connected with slide block, and the other end is fixed on fixed head.
Preferably, the parallel screw mandrel setting of described displacement transducer.

Preferably, the parallel screw mandrel setting of described pressure transducer.
Preferably, the data that described displacement transducer, pressure transducer obtain after the A/D module converts, by data collecting module collected, then send controller to process respectively, and the result after processing shows through display.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The described displacement and pressure measurement mechanism of the utility model scheme can reach an action and make displacement and two simultaneously-measured effects of parameter of pressure; The utility model scenario-frame is simple, and principle is clear, is convenient to study and grasps, and has solved simultaneously the problem of experimental facilities closure, and this programme do not need hydraulic system, has avoided pollution on the environment.
Description of drawings
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of displacement and pressure measurement mechanism described in the utility model;
Accompanying drawing 2 is the fundamental diagram of displacement and pressure measurement mechanism described in the utility model;
