A kind of physical balance described in above-mentioned patent, its reading pointer is the most elongated, and in actual mechanical process, pointer makes
Use to be easily bent and even fracture；When judging whether balance balances, it is to see pointer whether refer at reading crossbeam rise to carve
The central graduation position of scale or be directrix both sides work etc. with central authorities' scale scale swings, during reading can only by estimation contrast into
Row judges, due to the difference of observer's observation habit, causes read untrue, affects the precision of balance；Affected by accuracy of balance,
Pointer constructively will be as far as possible near read text scale dish, and both distances are typically between several millimeters, but apart from nearly balance
When crossbeam rises, pointer is easily encountered read text scale dish, is caused error in reading, even causes crossbeam to fall and falls damage.
Therefore, design a kind of Novel physical balance that can solve the problems referred to above well to be extremely necessary.
Utility model content
The purpose of this utility model is: provides a kind of high accuracy Novel physical balance, instead of tradition with laser pointer
Elongated reading pointer so that it is accuracy of reading, can improve accuracy of balance, the problem not enough to solve above-mentioned prior art.
To achieve these goals, this utility model adopts the following technical scheme that
A kind of high accuracy Novel physical balance, including base, column, support and crossbeam, also include laser pointer device and with
The read text scale dish that laser pointer device matches, the upper end of described laser pointer device is vertically fixed on lower end in the middle part of described crossbeam,
The lower end of described laser pointer device is provided with yi word pattern crack, and described read text scale dish is located on column, and described read text scale dish is
Rectangle and its place plane are vertical with the laser place plane that the yi word pattern crack on described laser pointer device is launched, described column
Being perpendicularly fixed at base central authorities, described column upper end is provided with support, and described support is fixing with column to be connected, and described support central authorities set
Having middle cutter torr, described support to be connected by middle cutter torr with crossbeam, the two ends of described crossbeam are provided with balance nut and limit cutter suspension bracket, institute
State and be provided with the scale pan below the cutter suspension bracket of limit；Described crossbeam upper end is provided with scale, and described crossbeam upper end is provided with rider, and described rider is with horizontal
Beam is slidably connected.
Preferably, described base two ends are provided with horizontal screw.
Preferably, the lower end of described column is provided with switching knob.
The beneficial effects of the utility model are: with laser in place pointer, by yi word pattern slit, launch yi word pattern and swash
Light, yi word pattern laser shines directly into and directly contrasts with scale on read text scale dish, accuracy of reading, and precision is high, it is to avoid
Owing to the difference of observer's observation habit causes error in reading, improve accuracy of balance；Solve traditional elongate pointer using
Journey is easily bent the problem even fractureed；Laser brightness is high, visual good, is susceptible to external environment during balance uses
Impact；Can protect crossbeam, laser pointer, will not be with balance column or reading in balance operating process with laser as pointer
Graduated disc is collided, and can well prevent owing to pointer and pillar or the read text scale dish crossbeam brought of colliding falls and falls damage.
