The tray balance is characterized in that the bottom of the base is provided with a height adjusting nut and a horizontal ruler, the horizontal ruler is located at a transverse middle position of the base, a pair of spring pieces are fixed to the upper surface of the base, extension springs are installed at end parts of the spring pieces, the support is fixed to the base, the top end of the support is provided with a dividing plate, the crossbeam is installed on a knife edge, which is fixed to the support, through a circular hole, a sliding weight is installed on the crossbeam, each of two ends of the crossbeam is provided with a tray support and a balance nut, the middle part of the crossbeam is provided with a pointer, the top of the pointer is provided with a magnifier, a center line is disposed on the magnifier, the crossbeam is provided circular hole corresponding to end parts of the spring pieces, the crossbeam body is provided with scale, and trays are disposed on the tray supports. The tray balance is novel in design and reasonable in structure; and not only is the knife edge fully protected, but also accuracy of measuring results is greatly improved.
Description
Technical field
The utility model relates to weighing apparatus tool technical field, refers in particular to a kind of counter balance.
Background technology
Conventional one weighing apparatus tool in counter balance scientific research practice, whether weighing result is accurate, directly affects the accuracy of result of study.Traditional balance exists following not enough: first, the base of traditional balance is unadjustable, makes the contact angle of the edge of a knife and crossbeam indefinite, and measurement result can exist deviation; Secondly, traditional balance is reading pointer position from index plate directly, is subject to the restriction of resolution of eye, and the accuracy of reading is limited; Finally, traditional balance is moving up in process, and the edge of a knife and crossbeam easily bump, and can accelerate like this wearing and tearing of the edge of a knife, affect accuracy of measurement.
Summary of the invention
The object of the utility model patent is to address the above problem, a kind of counter balance is provided, comprise base, support and crossbeam, it is characterized in that: base bottom is provided with height setting nut and surveyor's staff, and surveyor's staff is positioned at the horizontal centre position of base, on upper surface, be fixed with a pair of spring leaf, the end of spring leaf is provided with extension spring, support is fixed on base, cantilever tip is provided with index plate, crossbeam is arranged on by circular hole on the edge of a knife being fixed on support, rider is installed on crossbeam, two ends are respectively provided with tray supporter and balance nut, middle part is provided with pointer, pointer top is provided with magnifier, magnifier is provided with center line, corresponding with the spring leaf end circular hole that is provided with on crossbeam, cross-beam body is provided with scale, tray supporter is provided with pallet.
The beneficial effects of the utility model are: the utility model modern design, and rational in infrastructure, can effectively improve the accuracy of measurement result.With the base of height setting nut and surveyor's staff, base is realized adjustable; Be provided with the pointer of magnifier, make index plate reading more accurate; The design of extension spring, makes in balance moving process, and the edge of a knife and crossbeam keep flexible contact, and the edge of a knife has adequately protected.
accompanying drawing explanation:
Fig. 1 is the utility model structural representation.
embodiment:
With reference to Fig. 1, the utility model is a kind of counter balance.
The purpose of this utility model realizes as follows: a kind of counter balance, comprise base 14, support 16 and crossbeam 10, it is characterized in that: base 14 bottoms are provided with height setting nut 15 and surveyor's staff 13, and surveyor's staff 13 is positioned at the horizontal centre position of base 14, on upper surface, be fixed with a pair of spring leaf 12, the end of spring leaf 12 is provided with extension spring 11, support 16 is fixed on base 14, support 16 tops are provided with index plate 7, crossbeam 10 is arranged on by circular hole on the edge of a knife 9 being fixed on support, rider 4 is installed on crossbeam 10, two ends are respectively provided with tray supporter 3 and balance nut 2, middle part is provided with pointer 8, pointer 8 tops are provided with magnifier 6, magnifier 6 is provided with center line, corresponding with the spring leaf 12 ends circular hole 17 that is provided with on crossbeam 10, crossbeam 10 bodies are provided with scale 5, tray supporter 3 is provided with pallet 1.The utility model modern design, rational in infrastructure, can effectively improve the accuracy of measurement result.With the base 14 of height setting nut 15 and surveyor's staff 13, base 14 is realized adjustable; Be provided with the pointer 8 of magnifier 6, make index plate 7 readings more accurate; The design of extension spring 11, makes in balance moving process, and the edge of a knife 9 and crossbeam 10 keep flexible contact, and the edge of a knife 9 has adequately protected.
