Background technology
Physical balance is the instrument weighing mass of object, is frequently used in experimental teaching and laboratory.It is according to lever
Equilibrium principle is made, and the fulcrum in the middle of crossbeam is divided into two arms in left and right crossbeam, each arm respectively hangs with pallet, a pallet
In place testee, in a pallet place counterweight, crossbeam lower end middle position is equipped with pointer.When weighing mass of object, rise
Play crossbeam, see throw of pointer situation, if pointer is referred in read text scale disk centre position or made for directrix both sides with centre position
When swinging Deng scale, then judge that balance is balance.
In prior art, the patent documentation of Publication No. cn204831489u discloses a kind of physical balance, and it includes bottom
Seat, pillar, support and rider bar, described pillar is located in the middle part of base, is fixedly connected with base, and described is erected at pillar
On, it is fixedly connected with pillar, described mid-stent is provided with edge bearing, described rider bar is connected with support by edge bearing, described
Be provided with sensibility reciprocal actuator, reading pointer and pointer scale in pillar, described reading pointer, sensibility reciprocal actuator and rider bar according to
Secondary connection, described rider bar is provided with rider and balance nut, and described rider and rider bar are slidably connected, described rider
Scale two ends are provided with hook, are provided with the scale pan below described hook, and described scale pan side is provided with bracket.
A kind of physical balance described in above-mentioned patent, its reading pointer is extremely elongated, and in actual mechanical process, pointer makes
Use and be easily bent or even fracture；When judging whether balance balances, it is to rise crossbeam to see whether pointer refers to carve in reading
The central graduation position of scale or with central scale for directrix both sides make etc. scale swing, during reading can only by estimation contrast into
Row judges, due to the difference of observer's observation habit, leads to read untrue, the precision of impact balance；Affected by accuracy of balance,
Pointer constructively will as far as possible near read text scale disk, both distances typically between several millimeters, but apart from nearly balance
When crossbeam rises, pointer easily encounters read text scale disk, causes error in reading, or even causes crossbeam to fall to fall damage.
Therefore, design a kind of novel physical balance that can solve the above problems well to be extremely necessary.
Utility model content
The purpose of this utility model is: provides a kind of laser type pointer physical balance, instead of tradition with laser pointer
Elongated reading pointer, so as to accuracy of reading, can improve accuracy of balance, not enough to solve the problems, such as above-mentioned prior art.
To achieve these goals, this utility model adopts the following technical scheme that
A kind of laser type pointer physical balance, including base, column, support and crossbeam, also include laser pointer device and with
The read text scale disk 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 on column, described read text scale disk is described read text scale disk
Fan-shaped and its place plane is parallel with the laser place plane that the yi word pattern crack on described laser pointer device is launched, described column
It is perpendicularly fixed at base central authorities, described column upper end is provided with support, and described support is fixedly connected with column, and described support central authorities set
There is middle knife support, described support is connected by middle knife support with crossbeam, the two ends of described crossbeam are provided with balance nut and side knife suspension bracket, institute
State and be provided with the scale pan below the knife suspension bracket of side.
Preferably, described base two ends are provided with horizontal screw.
Preferably, described crossbeam upper end is provided with scale.
Preferably, described crossbeam upper end is provided with rider, and described rider and crossbeam are slidably connected.
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 is shone directly into and is directly contrasted with scale on read text scale disk, accuracy of reading, it is to avoid due to observing
The difference of person's observation habit causes error in reading, improves accuracy of balance；Solve traditional elongate pointer easy in use
The problem that bending even fractures；Laser brightness is high, visual good, is difficult to be affected by external environment during balance uses；
Crossbeam can be protected, laser pointer is with laser as pointer, will not be with balance column or read text scale disk in balance operating process
Collide, can prevent well to fall and fall damage due to the pointer and pillar or read text scale disk crossbeam bringing of colliding.
