Abstract

The utility model relates to a balance scale, which comprises a base, a supporting rod, a balancing arm, a weight supporting tray, weights and an indicator marking disc, wherein the bottom end of the supporting rod is vertically fixed on the surface of the base, and the top end is movably connected with the middle point of the balancing arm; a sector indicator marking disc is arranged on the supporting rod to be close to the top end of the supporting rod; and a plurality of illumination bulbs are installed on the top edge of the indicator marking disc. When in use, the objects to be measured and the weights are respectively arranged on the left and the right supporting trays, so the weight of the object to be measured can be obtained by observing the weight of the weights under the condition that the balancing arm is levelly maintained; and when the light is weak or in blackness, the switch can be turned on, so the illumination bulbs can illuminate the indicator marking disc so as to provide a bright observing environment to the user. The balance scale has the advantages of reasonable structure, convenience, practicability, wide application and the like.

Description

Balance

Technical field the utility model relates to a kind of survey instrument, especially a kind of balance.

Background technology is in Physical Experiment or industrial check weighing, and people use balance as survey instrument through regular meeting.Yet,, but still be subjected to the influence of applied environment though present balance increases on measuring accuracy.Particularly under the more weak environment of light, people can't accurately observe the balance display disc, have a strong impact on measuring accuracy.In order to address the above problem, we provide a kind of new-type balance.

The summary of the invention the purpose of this utility model provides a kind of balance, and the observing effect that is used to solve general utility balance is subjected to ambient light to influence bigger problem.

For achieving the above object, the utility model balance comprises base, support bar, balance arm, weight tray, counterweight and pointer sign dish, and the support bar bottom vertically is fixed on susceptor surface, top and balance arm mid point flexibly connect, and the end points place hangs weight tray respectively in the balance arm left and right sides; Near the apical position place fan-shaped hand sign dish is installed at support bar, and pointer indicates the limit level of trying to get to the heart of a matter, bisector overlaps with support bar; At pointer sign dish top margin a plurality of lighting bulbs are installed, a plurality of lighting bulbs and battery, switch are composed in series lighting circuit.

After adopting said structure, during use, the user places determinand and counterweight by left and right sides pallet, keeps observing counterweight weight under the situation of balance arm level, thereby draws the weight of determinand; When light is more weak or unglazed, but user's Closing Switch, by the luminous pointer sign dish that illuminates of lighting bulb, for the user provides bright eye-catching environment of observation.

Compared with the prior art, the beneficial effects of the utility model are: rational in infrastructure, convenient and practical, be widely used, and not influenced by ambient light, the measuring condition that facilitates.

Description of drawings Fig. 1 is the one-piece construction synoptic diagram of the utility model balance.

Number in the figure: 1 is that base, 2 is that support bar, 3 is that balance arm, 4 is that weight tray, 5 is that counterweight, 6 is that pointer sign dish, 7 is a lighting bulb.

Embodiment as shown in Figure 1, the utility model balance, comprise base 1, support bar 2, balance arm 3, weight tray 4, counterweight 5 and pointer sign dish 6, support bar 2 bottoms vertically are fixed on base 1 surface, top and balance arm 3 mid points flexibly connect, and the end points place hangs weight tray 4 respectively in balance arm 3 left and right sides; Near the apical position places fan-shaped hand sign dishes 6 are installed at support bar 2, and the pointer sign coils 6 base levels, bisector overlaps with support bar 2; Coil 6 top margins in the pointer sign a plurality of lighting bulbs 7 are installed, a plurality of lighting bulbs 7 are composed in series lighting circuit with battery, switch.
