Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

In one embodiment of the electronic balance for weighing and testing plastic according to the present invention as shown in fig. 1 and fig. 2, the electronic balance comprises a base 1; a metering tray 2 for placing a weighing product and a windshield 3 for preventing air from flowing are arranged on the base 1; the windshield 3 comprises a detachable bracket 4 and transparent wind shields 5 arranged on each surface of the bracket 4; the base 1 is provided with a slideway 11 for the wind shield 5 to slide back and forth; the metering tray 2 is arranged at the center of the top surface of the base 1; the base 1 is provided with an ash storage disc 6 for cleaning and storing scattered weighed materials; a positioning rod 12 for preventing the ash storage disc 6 from moving is arranged on the base 1; the ash storage tray 6 is provided with a handle 61, a positioning hole matched with the positioning rod 12, an inner wall 62 matched with the metering tray 2 and a middle hole surrounded by the inner wall 62; at least one wind deflector 5 is provided with a through hole 51 which can be opened and closed; a through seam 111 for cleaning scattered objects is discontinuously arranged on one sliding wall of the slide way 11 away from the metering tray 2; the bottom of the wind shield 5 arranged on the slideway 11 is provided with a rail cleaner 52 for cleaning the scattered objects in the slideway 11. Through the storage dish that is located low department of design on the base, in weighing the thing and scattering the back available brush and cleaning into the storage dish, keep the inside clean and tidy of balance, the thing corrosive apparatus of weighing of avoiding scattering, the cooperation design of leading to seam and clear rail ware on the slide is convenient for clear up the slide, avoids weighing the thing and scatters into the slide, causes the deep bead inconvenient that slides, reduces the collision risk.

Specifically, the through hole 51 is provided with a silica gel plugging sheet, the middle part of which can only pass through the handle of the medicine spoon 7. The sealing piece for the medicine spoon handle to pass through ensures the airtightness of the inside of the equipment, and can also ensure that redundant weighing products are separated under the condition of no gas flow, thereby accurately weighing the precision.

Specifically, the rail cleaner 52 may be a triangular prism with square edges abutting the sliding walls of the metering tray 2. Through designing the clear rail ware of right angled triangular prism and pushing out the unobstructed nature of slide with the scattered thing in the slide through the seam assurance slide, and can form the inclined plane and clean the scattered thing with the brush cooperation.

Specifically, the top surface of the base 1 is designed as a tapered surface. Guarantee through the design conical surface that the storing dish is located the minimum, guarantee all scattered thing on the base all can collect into the storing dish in, guarantee the cleanliness of equipment.

Specifically, the height of the positioning rod 12 is greater than the sum of the heights of the ash tray 6 and the weighing tray 2. Through the height of injecing the locating lever, guarantee that ash storage tray does not take place friction or collision with the measurement tray at the removal in-process, guarantee the accuracy nature of equipment.

Specifically, the bottom surface of the metering tray 2 is lower than the top surface of the inner wall 62; the top surface of the metering tray 2 is higher than the top surface of the inner wall 62. The thickness of the metering tray is limited, and a closed space is formed between the metering tray and the inner wall, so that the weighing product is prevented from scattering into the bottom of the metering tray to corrode an electronic device; ensuring the cleanness and the precision of the equipment.

The working principle is as follows: when a user weighs, the wind shield 5 is opened, filter paper or a weighing dish is placed on the metering tray 2, a sample medicine spoon is placed on the weighing dish according to needs, and after the reading is slightly higher than the needed value, the wind shield 5 is closed to form a sealed bin body; after standing for a period of time, removing the redundant sample on the weighing vessel through the medicine spoon 7 penetrating through the silica gel plugging sheet, opening the wind shield 5 after ensuring that the weight is required, and putting the sample in the medicine spoon 7 into the sample container; if the weighed objects are scattered in the weighing process, the brush is held by hands to clean the equipment, so that the scattered objects are enabled to completely enter the ash storage disc 6 under the action of the conical surface, after the weighing is finished, the handle 61 is moved, the ash storage disc 6 is moved upwards along the positioning rod 12, the ash storage disc 6 is taken out, the magazines collected in the ash storage disc 6 are cleaned, and then the ash storage disc 6 is installed on the positioning rod 12 again; open wind shield 15 to maximum position, promote wind shield 15 and make its one side that is equipped with clear rail ware 52 to lead to seam 111 position in proper order, use the brush to clean slide 11, outside the scattered thing flows through seam 111 through the inclined plane of clear rail ware 52 under the brush effect, guarantee wind shield 5's smooth use.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
