Abstract
The utility model provides an electronic force measuring instrument. A force measuring spring is positioned at the left end of an inner cavity of a shell, and a transmission gear is arranged in the inner side at the right end of the inner cavity of the shell, wherein a rotating shaft of a force variable potentiometer or a force variable capacitor is sheathed in a central hole of the transmission gear; a transmission rack engaged with the transmission gear is arranged in the inner cavity of the shell side at the lower side of the transmission gear; one end of the transmission rack is connected with the force measuring spring, and the other end of the force measuring spring is arranged at the outer side of the right end of the shell and is provided with a force measuring hook; the outer wall at the lower side of the shell is positioned with an outer shell in which a force direction variable potentiometer or a force direction variable capacitor is positioned; a rotating shaft of the force direction variable potentiometer or the force direction variable capacitor passes through the shell and is connected with a fixed base at the end part of the shell. The utility model not only can measure both the tensity and the direction of force, and simultaneously can record and display measured results through an electronic device.
Description
Technical field
The utility model relates to a kind of device for measuring force, the electronics dynamometer of especially a kind of size of energy measurement power and direction.
Background technology
Being used for the Lab of General Physics chamber at present measures power and mostly uses spring balance, and during with the spring balance dynamometry, can only measure its size, its direction of energy measurement not, its measurement result can not and show by the electronic equipment record simultaneously, at this moment adopts the existing unconquerable defective of spring balance dynamometry in the Lab of General Physics chamber.
Summary of the invention
The purpose of this utility model is for the Lab of General Physics chamber provides a kind of size, the direction of energy measurement power again that can ergometry, simultaneously can also be measurement result by electronic equipment record and the electronics dynamometer that shows.
For realizing the purpose of this utility model, be achieved through the following technical solutions: the left end at the housing inner chamber is positioned with dynamometer spring, inboard at housing inner chamber right-hand member is provided with transmission gear, the rotating shaft of strong variable size potentiometer of suit or variable condenser in the center pit of transmission gear, in the shell-side inner chamber of transmission gear upside, be provided with the driving rack that is meshed with transmission gear, one end of this driving rack is connected with dynamometer spring, its other end places the housing right-hand member outside and is provided with the dynamometry drag hook thereon, on the downside outer wall of housing, be positioned with a shell, be positioned with force direction variable potentiometer or force direction variable condenser in this shell, the rotating shaft of this force direction variable potentiometer or force direction variable condenser connects a firm banking by shell and in its end.In order to prevent the driving rack swing, in the shell inner cavity in transmission gear left side, be provided with spacing catch.
Owing to taked technique scheme, during with the utility model dynamometry, be fixed on the surface level by firm banking, when the dynamometry drag hook is applied a pulling force, dynamometer spring deformation, driving rack move to right, drive the transmission gear rotation, and drive variable size potentiometer or power variable size electrical equipment rotate simultaneously, thereby cause the variation of its resistance value or electric capacity, this changing value is sent in the electronic equipment record and show, thereby finish the task of the size of ergometry.When rotating in the surface level of traction dynamometry drag hook, with drive direction potentiometer or capacitor transmission, thereby cause the variation of its resistance or electric capacity, this changing value is sent in the electronic equipment record and show, thereby finish the task of the direction of ergometry.
The beneficial effects of the utility model are to finish the size of paired forces and the task of orientation measurement simultaneously, and the special electronic equipment by configuration also can and show the measurement result record simultaneously.The utility model also has characteristics simple in structure, easy to use, that section emulates the advanced.
