Authorization Notice No. CN 206038138U disclose " a kind of electronic balance ", including pedestal and weighing plate, weighing plate peace Mounted in the top of pedestal, pressure sensor is equipped between weighing plate and pedestal, pressure sensor is fixed in pedestal, is set in pedestal It is equipped with circuit board, circuit board is electrically connected with pressure sensor, and the top of pedestal is equipped with workbench, and workbench is enclosed equipped with baffle, Baffle includes two fixed plates and two pieces of movable plates, and two fixed plates are separately positioned on the front and rear sides of workbench, two pieces of movements Plate is separately positioned on the left and right sides of workbench；The top of pedestal is equipped with the groove for being embedded in movable plate, and groove is along pedestal Width direction extends to the edge of pedestal；The bottom end of two pieces of movable plates is equipped with pulley, and the height of groove is higher than the height of pulley, recessed The width of slot is equal to the thickness of pulley.

Above-mentioned electronic balance needs to open door body, chemical agent is added in weighing plate when weighing, and door body, which is opened, to be needed It is additional to occupy certain space, it is more difficult that door body is opened for narrow space；In addition, after medicament weighs, often forget Note closes door body so that the weighing main part of electronic balance is easy the moisture absorption, influences the measurement accuracy of electronic balance.

Utility model content

After needing to occupy certain space and weigh to solve existing electronic balance when door body is opened, operator Member forgets the problem of closing door body, leading to the electronic balance moisture absorption, and the purpose of this utility model is to provide a kind of electronic balance.

To achieve the goals above, the utility model adopts the following technical solution：A kind of electronic balance, including pedestal, set The transparent cover set the pallet on pedestal and be fixed on pedestal, the pallet are located in transparent cover, the transparent cover For cylindrical shape, it is provided with opening on the side wall of the transparent cover, the side-wall outer side of the transparent cover, which is provided with, to be covered on out Mouthful rotation lid, the downside of the rotation lid is provided with extension, and the transparent cover bottom end is provided with to be rotated for extension The top of sliding slot, the rotation lid is provided with sealant, and the first limited post is provided on the transparent cover, and the rotation lid leans on One end of nearly first limited post is provided with handle, and described handle one end and rotation lid are hinged, and through-hole is arranged in the handle other end, The corresponding position that the rotation is placed on through-hole is provided with the second limited post being used cooperatively with through-hole, is fixed on the transparent cover It is provided with column, the column is located between the first limited post and rotation lid, and spring is provided between the column and rotation lid, One end of the spring is connect with column, the other end and the rotation lid connection of the spring.

When needing to weigh chemical reagent, the through-hole of handle is placed on the second limited post, moving handle, rotation lid leaves Opening, rotation lid are opened, and the through-hole being placed on the second limited post is placed on the first limited post, rotation lid are fixed, at this time Chemical reagent can be added into pallet, carry out the weighing of chemical reagent, it, will when electronic balance shows numerical value close to desired value The through-hole of handle is transferred to by the first limited post on the second limited post, rotates lid, and opening is in closed state, electronic balance Show the numerical value after stablizing；Moving handle again, rotation lid leave opening, take out chemical reagent；Opening is left in rotation lid During, spring is compressed, and handle is unclamped, and spring pushes rotation lid to be moved to opening direction, most in restoring deformation process It is covered in opening eventually.

Rotation is covered in moving process, is covered on the outside of transparent cover always, saves occupied space.

Using the above scheme, it after operating personnel weigh, it is not necessary that rotation lid is turned off manually, avoids forgetting to close rotation The problem of covering, causing the electronic balance moisture absorption.

The first limited post is provided on transparent cover, rotation, which covers, is provided with the second limited post, the first limited post and second Limited post is used cooperatively with through-hole respectively, and through-hole is located on the first limited post, and rotation lid is fixed, at this time can be transparent with intention It is put into chemical reagent in cover body, rotation lid springback influence is avoided to weigh process；Through-hole is located at the second limited post, pushes handle, can To be moved to rotation lid, for picking and placeing chemical reagent.

Using the above scheme, the through-hole of rotation lid is switched in the first limited post and the second limit intercolumniation, facilitates behaviour Make personnel's use；In addition, rotation lid is fixed by the first limited post, avoid rotation lid because accidentally closing, and causes to be added The chemical reagent of pallet is fallen, and ensures being normally carried out for weighing process.

Wherein, the material of the sealant is sponge.

Set the material of sealant to sponge so that rotation covers end and the active force of transparent cover is small, avoids rotating Abrasion is brought to transparent cover in lid rotation process.

Wherein, magnet is provided on the lateral wall of the opening, the rotation covers the iron plate for being provided with and being attracted for magnet.

In rotating lid springback process, magnet has suction to iron-stone, accelerates the movement of rotation lid, reduces electronics day The flat moisture absorption.

Wherein, the drying cup equipped with drier is placed in the transparent cover, the drier is discoloration silica gel.

Dry cup is placed in transparent cover, absorbs the aqueous vapor in transparent cover, and the electronic balance moisture absorption is avoided to influence to measure Accuracy.

Compared with prior art, advantageous effect of the utility model：The utility model electronic balance is provided with cylinder The transparent cover of shape, transparent cover sidewall opening, transparent cover side-wall outer side are provided with the rotation lid that lid runs mouth jointly, are covered in rotation In moving process, without increasing occupied space, it is convenient for the use of small space electronic balance；The utility model electronic balance is saturating The spring with rotation lid connection is provided on the column of bright cover body, after taking out chemical reagent from pallet, spring band turn is dynamic The step of manually rotating lid is omitted in lid rebound, while effectively reducing the moisture absorption problem of electronic balance；The utility model electronics Recoil of spring is arranged according to the practical process that weighs in balance, reduces manual steps, more convenient to use.
