Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Study an iron stand for travelling block feature, comprise base 1, support 2, locating clip 3, cross bar 4, locating clip 5, control module 6, motor 7, cord 8, travelling block 9, counterweight 10, rule 11;
Described support 2 is fixed on base 1, and cross bar 4 is fixed on support 2 by locating clip 1, and travelling block 9 is fixed on cross bar 4 front end by cord, and cross bar 4 front end is also fixedly installed rule 11, and support 2 upper end is by locating clip 25 fixed electrical machinery driver element; Described electric-motor drive unit comprises control module 6, motor 7 and battery, and the lower end of described motor is by cord linking springs dynamometer 13, and described weight beam 13 connects travelling block 9, and described travelling block 9 hangs counterweight 10.
In described electric-motor drive unit, described control module 6 controls motor 7 and operates, and control module can adopt speed control circuit, pulls the speed of weight beam 13 for controlling cord.
Described rule 11 is for observing the distance of travelling block 9 vertical direction movement, and described rule 11 zero graduation is in rule the top.
Further, the distance of the adjustable cross bar 4 of described locating clip 1 and base 1, for regulating travelling block 9 height.
Further, described locating clip 25 is adjustable, for regulating the relative height of motor 7 and control module 6 and travelling block 9.
Further, described rule 11 zero graduation is in rule bottom.
Further, described cross bar 4 is scalable, and knob 12 controls the flexible of cross bar 4, for observing in vertical direction with the pulling force reading shown in the weight beam 13 of certain orientation.
The iron stand course of work of described research travelling block feature is as follows:
First locating clip 1 and locating clip 25 is regulated, regulate the relative position of travelling block 9 and electric-motor drive unit, laboratory technician reads the position of travelling block 9 and record, opening electric-motor drive unit again makes motor 6 work, motor 6 can realize at the uniform velocity pulling weight beam 13 after working, and then make travelling block 9 at the uniform velocity increase, in travelling block 9 motion process, the reading that laboratory technician can read weight beam 13 is gone forward side by side line item, last laboratory technician's disable motor driver element makes motor 6 quit work, and laboratory technician reads travelling block 9 position and record.
The beneficial effects of the utility model are, by adopting electric-motor drive unit and rule, counterweight uniform motion can be realized more accurately, the convenient reading reading weight beam, and student can carry out reading comparatively accurately by rule to counterweight climb, simple, reasonable in design, the processing ease of this apparatus structure, demonstrating visual simultaneously.
