Abstract
The utility model discloses dynamometer facilitating accurate reading. The dynamometer comprises a support, a spring and a hook, wherein the upper end of the spring is fixed on the support, the lower end of the spring is connected with the hook and provided with a pointer, a calibrated scale is arranged on the support, the graduation lines of the calibrated scale are marked on the left and right sides, a magnifier is arranged on the surface of the pointer, and a handle is arranged on the upper end of the support. The graduation lines of the calibrated scale are marked on both left and right sides, thereby effectively increasing the distance between graduation lines, thereby enabling accurate reading. A magnifier installed on the surface of the pointer magnifies the graduation lines pointed, thereby facilitating observing and accurately reading. The dynamometer is delicate and portable.
Description
Technical field
The utility model relates to a kind of experimental apparatus dynamometer, relates in particular to a kind of dynamometer of being convenient to pin-point reading, belongs to middle school teaching utensil field.
Background technology
The dynamometer commonly used in the laboratory is weight beam, and along with the variation of testing force, the deformation of spring changes, and pointer indicates this deformation, thereby reads the size of power.Its weak point is that scale spacing is smaller, the reading out of true; If requiring has accurate reading, then the range of spring diminishes or rule becomes big.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of dynamometer of being convenient to pin-point reading easily at above deficiency.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of dynamometer of being convenient to pin-point reading, comprise support, spring and hook, the upper end of described spring is fixed on the described support, the lower end of spring links to each other with described hook and is provided with pointer, described support is provided with rule, it is characterized in that: the scale mark of described rule marks about being, described pointer surface is equipped with magnifier.
As a kind of prioritization scheme, described support upper end is provided with handle.
The utility model adopts above technical scheme, compared with prior art, has the following advantages: mark about by the scale mark of taking rule being, effectively increased scale spacing, and reading is accurate; Magnifier by install on the pointer surface can amplify pointer indication scale, is convenient to observe with accurately most, exquisite, portable.
Below in conjunction with drawings and Examples the utility model is elaborated.
Description of drawings
Fig. 1 is the structural representation of dynamometer among the utility model embodiment;
Among the figure,
The 1-support; The 2-handle; The 3-spring; The 4-pointer; The 5-magnifier; The 6-rule; The 7-hook.
Embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.In the following detailed description, only by the mode of explanation some one exemplary embodiment of the present utility model has been described.Undoubtedly, those of ordinary skill in the art can recognize, under the situation that does not depart from spirit and scope of the present utility model, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used for the protection domain of restriction claim.
Embodiment, as shown in Figure 1, a kind of dynamometer of being convenient to pin-point reading comprises support 1, spring 3 and links up with 7, described support 1 upper end is provided with handle 2, the upper end of described spring 3 is fixed on the described support 1, and the lower end of spring 3 is provided with pointer 4, and the lower end of spring 3 links to each other with described hook 7 by connecting rod, described spring below is provided with rule 6, described rule 6 is fixed on the described support 1, and the scale of described rule 6 mark marks about being, described pointer 4 surfaces are equipped with magnifier 5.
The dynamometer of being convenient to pin-point reading of the present utility model, by the scale mark of taking rule 6 be about mark, effectively increased scale spacing, make reading more accurate, convenient; Magnifieres 5 by install on pointer 4 surface can amplify pointer indication scale, are convenient to observe and accurately most, and rule 6 need not be become big, make that dynamometer is exquisiter, portable and deposit.
