Description

A kind of assay balance

Technical field

The utility model relates to the technical fields of assay balance, more particularly, to a kind of assay balance.

Background technique

Assay balance is most important instrument when carrying out precise in experiment, it can be divided into mechanical and electrical type, Mechanical assay balance can be subdivided into general analysis balance, air lamping balance and single counter balance etc., these balances are all benefits With lever principle, but it is different in structure and in application method, and mechanical balance can satisfy the standard of general quantitative analysis Exactness requirement, sensitivity are 0.1 mg, and the great advantage of such balance is structural visual, but balance zero is complicated, and operation is wanted Seek high mesh and time-consuming.

Existing Authorization Notice No. is that the Chinese patent of CN204177471U discloses a kind of automatic horizontal adjusting electronics point Balance is analysed, is made of pedestal, outer cover and weighing plate, be equipped with weighing plate at the top of the base and has outer cover to cover on pedestal, bottom The extension surface of seat front side is embedded with liquid crystal display, and the front end of extension bottom is equipped with spiral foot, and the inside of pedestal is equipped with place Manage device, gravitational equilibrium module, switch module, leveling motor, power module, weighing sensor and display module, processor difference With gravitational equilibrium module, switch module, leveling motor, power module, weighing sensor and display module circuit connection, mould is shown Block and liquid crystal display circuit connection, leveling motor and spiral foot are mechanically connected.

Prior art among the above has the following deficiencies: assay balance when not in use if straight by sunlight for a long time It penetrates, the precision of assay balance itself will receive influence, cause measurement data error occur, so as to cause survey crew institute when test There is error in the data needed.

Utility model content

The purpose of the utility model is to provide one kind can protect balance when not in use not by the analysis day of direct sunlight It is flat.

The purpose of this utility model has the technical scheme that

A kind of assay balance, including pedestal, are provided with hurricane globe on the pedestal, on the pedestal and are located in hurricane globe It is provided with weighing plate, on the pedestal and is located at outside hurricane globe and is provided with hood, the four of hurricane globe are arranged in the hood On a side wall, the top of the hurricane globe and it is located on four seamed edges of hurricane globe and is provided with framework, in the framework and is located at Four corners of framework offer sliding slot, and the sliding slot runs through framework along the vertical direction and is arranged, on the inner wall of the hood It is provided with the draw runner being slidably connected in four sliding slots respectively, is provided at the top of the hurricane globe for driving hood along perpendicular Histogram is to mobile driving device.

By using above-mentioned technical proposal, when being detected using assay balance, start driving device, driving device meeting Driving hood is moved upwardly by along vertical direction, and hood then will drive draw runner in sliding in sliding slot, when hood is moved to Driving device can then be closed when at the top of hurricane globe, staff opens that inspected object is placed on weighing plate by hurricane globe again can be into Row weighs, and after use, staff is again started up driving device, so that hood moves downward along the vertical direction, until The bottom end of hood is abutted to pedestal, entire assay balance can so be covered up, and is protected it from by direct sunlight, from And it ensure that the detection accuracy of assay balance；And the setting of sliding slot and draw runner can play guiding role to the movement of hood, Move hood along vertical direction.

The utility model is further arranged to: the driving device includes the motor being arranged at the top of hurricane globe, the electricity The coaxially connected position on gear, the inner wall of the hood and where being located at gear is provided with rack gear on the output shaft of machine, The rack gear is arranged along the vertical direction, and the wheel and rack intermeshes setting.

By using above-mentioned technical proposal, after starting motor, motor meeting sliding tooth wheel rotation, at this time due to rack and pinion It is meshed, and rack gear is placed in the vertical direction, so gear meeting drive rack moves along vertical direction, rack gear is when moving It is mobile then to will drive hood, to realize moving up and down for hood, wheel and rack it is relatively simple for structure, and have Higher transmission accuracy can preferably drive hood mobile.

The utility model is further arranged to: being provided with anticreep on the inner wall of the hood and positioned at the lower part of hood Block.

By using above-mentioned technical proposal, when hood is moved upwardly by and is moved to the top of hurricane globe, on hood Anti-drop block can abut to framework, such anti-drop block, which may be prevented from hood, to be continued to be moved upwardly by, to prevent hood de- From framework.

The utility model is further arranged to: the hood is provided with buffer bar on the end face of pedestal, described slow It rushes item and is circumferentially arranged along hood.

By using above-mentioned technical proposal, the setting of buffer bar so that hood will not be touched directly on pedestal, thus Certain protection is all formd to hood and assay balance.

The utility model is further arranged to: the cross-sectional shape of the sliding slot is set as "T"-shaped, the draw runner and " T " The sliding slot of shape is equipped with.

By using above-mentioned technical proposal, " T " shaped sliding slot and draw runner can prevent draw runner from being detached from sliding slot, so that hood It can preferably be fixed in framework.

The utility model is further arranged to: being provided with closed plate at the top of the hood.

By using above-mentioned technical proposal, closed plate can prevent dust from entering inside hood, thus to motor, gear And rack gear forms protection.

The utility model is further arranged to: the closed plate is removably connected on hood.

It, can be by closed plate from hood when motor or other component are damaged by using above-mentioned technical proposal It disassembles, in order to be repaired to motor.

The utility model is further arranged to: the hood is described to insert far from offering inserting groove on the section of pedestal Access slot is circumferentially arranged along hood, is provided with the grafting item being plugged in inserting groove in the closed plate.

By using above-mentioned technical proposal, when needing to dismantle closed plate, so that grafting item is detached from inserting groove may make closing Plate and hood are detached from, and when install closed plate, make in grafting item immigration inserting groove can fixed closed plate on hood, So that the peace of closed plate tear open it is all more convenient.

In conclusion the advantageous effects of the utility model are as follows:

1. starting driving device driving hood moves downward along the vertical direction, so that hiding when not using assay balance Light shield drives draw runner in sliding in sliding slot, and covers hood by entire hurricane globe, so may make analysis day It puts down not by direct sunlight, ensure that the detection accuracy of assay balance；

2. being rotated by motor driven gear, so that gear drives the rack gear engaged mobile, so that rack drives hide Light shield moves along the vertical direction, and the structure of wheel and rack is simple, and transmission accuracy is higher, preferably hood can be driven to move It is dynamic；

3. forming closed plate to the motor in hood by the way that dismountable closed plate is arranged on hood Protection, and closed plate can be removed in motor damage, motor is repaired.
