Abstract
The utility model discloses a student uses weight beam, including couple, shell, quartzy calibrated scale, connecting piece, gua quan, spring, pull rod and display, shell surface mounting has quartzy calibrated scale, and the centre installation, the spring mounting is inside the shell, the pull rod is installed under the spring, the spring passes through the pull rod and is connected with the couple, the display passes the pull rod and installs in the shell lower part, the connecting piece is installed at the shell upside, and the centre installation, it is connected with the shell through the connecting piece to hang the circle. The utility model discloses a weight beam has improved the spring -mass on traditional dynamometer basis, improved measurement accuracy and sensitivity, and the visual scope of reading is big, and can contrast through the data that the calibrated scale read with the student through the display, and education of school nature is better, and the testing process allows all -round no dead angle rotatory, and the practicality is stronger, is applicable to school's laboratory teaching and uses.
Description
Technical field
The utility model relates to the teaching equipment field of ergometry, is specially a kind of student's weight beam.
Background technology
Weight beam is a kind of instrument of dynamometry size, to be user of service link up with pulling traditional weight beam, make the process of spring generation deformation, any measurement is all the process some physical quantitys compared with standard (i.e. unit), the measurement of power is exactly the process compared with the action effect of known force by the action effect of power, if the action effect of a power is identical with the action effect of 1 Niu Li, the size of this power is exactly 1 N, secondly the elongation of spring is directly proportional to stressed size, after the action effect determining 1 Niu Li, easily determine the action effect of larger power and less power, in addition, the stability of spring is better, can reuse, therefore the size of weight beam ergometry can be used, but weight beam is traditionally waited in use and accidentally will be exceeded its range, because the reason of spring-mass will cause the state that cannot restore to the original state, its precision will be affected when next time uses.
Utility model content
The purpose of this utility model is to provide a kind of student's weight beam, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of student's weight beam, comprise hook, shell, quartz index dial, web member, hanging ring, spring, pull bar and display, described case surface is provided with quartzy index dial, and quartzy index dial center is installed, described spring fitting portion in the enclosure, and top set welded and installed, under described pull bar is arranged on spring, described spring is connected with hook by pull bar, described display is arranged on outer casing underpart through pull bar, described web member is arranged on the upside of shell, and center is installed, described hanging ring is connected with shell by web member.
Preferably, described quartzy index dial is provided with liquid crystal display pointer.
Preferably, described spring is provided with pressure transducer, and pressure transducer is by being through electric wire on pull bar and display is electrically connected.
Preferably, described display is provided with shift knob.
Compared with prior art, the beneficial effects of the utility model are: the weight beam of this student, case surface is provided with quartzy index dial, and quartzy index dial center is installed, quartz index dial is provided with the display of liquid crystal display pointer, this weight beam sensitivity is higher, measuring accuracy is better, be easy to observe, spring fitting is portion in the enclosure, under pull bar is arranged on spring, spring is connected with hook by pull bar, display is arranged on outer casing underpart through pull bar, spring is provided with pressure transducer, and be electrically connected by the electric wire that is through pull bar inside and display, display is provided with shift knob, by being provided with pressure transducer on spring, by the size knowing now pulling force that valve display device can be more accurately clear and intuitive, measure with student oneself data read better to contrast, more effectively judge that whether the data oneself read are correct, web member is arranged on the upside of shell, and center is installed, described hanging ring is connected with shell by web member, also can this weight beam be hung on support, the value of thrust of now weight beam is judged by lower extension weight.
