[0039] Example 1

[0040] Reference Figures 1 to 7 The utility model provides a portable quality inspection balance, including a balance body 1, a leveling mechanism 2 is installed at the bottom of the balance body 1, a windproof frame 3 is installed above the balance body 1, the windproof frame 3 includes a fixed support frame 300 and an L-shaped mounting plate 301, the L-shaped mounting plate 301 is rotatably connected to the fixed support frame 300, and a feeding mechanism 4 is installed on the L-shaped mounting plate 301;

[0041] A carrier plate 500 is installed on the balance body 1 through the state control component 5 .

[0042] The working principle and beneficial effects of the above technical solution are as follows: when working, the state control component 5 is adjusted to put the quality inspection balance in the working state, and then it is leveled by the leveling mechanism 2. After the leveling is completed, the quality inspection balance is self-checked by the weight. If the measurement result is wrong, the quality inspection balance is calibrated. If the measurement result is accurate, the sample carrying container to be measured is placed on the carrier 500, and then the sample to be measured is placed in the feeding mechanism 4, and the material is added into the sample carrying container to be measured by the feeding mechanism 4;

[0043] The designs of the leveling mechanism 2 and the windproof frame 3 of the utility model are beneficial to improving the detection accuracy of the quality inspection balance. At the same time, the feeding mechanism 4 replaces manual feeding, avoiding the situation where manual feeding easily causes sample contamination and easily causes hand shaking to squeeze the quality inspection balance, resulting in a large final detection error.

[0044] Example 2

[0045] On the basis of Example 1, an operation panel 100 is provided on the front side of the balance body 1, and a balance level is provided on the operation panel 100, and the balance level is used to detect in real time whether the balance is in a horizontal state;

[0046] The leveling mechanism 2 includes a leveling screw 200, which is threadedly connected to the bottom of the balance body 1 and positioned by a positioning nut 201.

[0047] The hollow support 203 is in the shape of a trumpet.

[0048] The working principle and beneficial effects of the above technical solution are as follows: during leveling, observe the position of the liquid drop on the balance level, and adjust the height of the four hollow supports 203 so that the liquid drop is in the middle position. Specifically, manually rotate the leveling nut 202 so that the leveling nut 202 moves up and down along the leveling screw 200 under the action of the thread, thereby achieving adjustment of the height of the hollow support 203. At the same time, the hollow support 203 is trumpet-shaped, which can improve the stability of the quality inspection balance.

[0050] On the basis of Example 1, the L-shaped mounting plate 301 is fixedly connected to the regulating shaft 3010 , the regulating shaft 3010 is rotatably connected in the fixed support frame 300 , and one end of the regulating shaft 3010 is fixedly connected to a hand-cranked turntable 3011 .

[0051] The working principle and beneficial effects of the above technical solution are as follows: when coarsely adjusting the spatial position of the feeding mechanism 4, the hand-cranked turntable 3011 is manually shaken to drive the regulating shaft 3010 to rotate, and the regulating shaft 3010 drives the L-shaped mounting plate 301 to rotate, and the L-shaped mounting plate 301 rotates to coarsely adjust the spatial position of the feeding mechanism 4 thereon.

[0052] Example 4

[0053] Based on Example 1, the feeding mechanism 4 includes a feeding funnel 400, a connecting hose 401 and a feeding body 402. The feeding funnel 400 is fixedly connected to the top of the L-shaped mounting plate 301, the feeding body 402 is rotatably connected to the side of the L-shaped mounting plate 301, and the two ends of the connecting hose 401 are respectively connected to the feeding funnel 400 and the feeding body 402.

[0054] The working principle and beneficial effects of the above technical solution are as follows: during operation, the sample to be measured is poured in through the feed funnel 400, and then the sample enters the filling body 402 through the connecting hose 401, and is fed into the sample holding container to be measured through the filling body 402. The design of the connecting hose 401 ensures the degree of freedom required for fine-tuning the position of the filling body 402.

[0055] Example 5

[0056] On the basis of Example 4, the adding body 402 includes a adding body shell 4020, and a tilt adjustment shaft 4021 is fixedly connected to the side of the adding body shell 4020, and the tilt adjustment shaft 4021 is rotatably connected to the L-shaped mounting plate 301, and one end of the tilt adjustment shaft 4021 is fixedly connected to a driven wheel 4022, and an adjustment drive motor 4023 is fixedly connected inside the L-shaped mounting plate 301, and an active wheel 4024 is fixedly connected to the output end of the adjustment drive motor 4023, and the active wheel 4024 and the driven wheel 4022 are meshed with each other.

[0057] The working principle and beneficial effects of the above technical solution are as follows: when fine-tuning the spatial position of the filling main body shell 4020, the driving motor 4023 is adjusted to drive the active wheel 4024 to rotate, the active wheel 4024 drives the driven wheel 4022 to rotate, and the driven wheel 4022 drives the filling main body shell 4020 to rotate, thereby fine-tuning the spatial position of the filling main body shell 4020.

[0058] Example 6

[0059] On the basis of Example 4, the feeding body 402 is rotatably connected to an electric feeding turntable 403 in the feeding body shell 4020, and the electric feeding turntable 403 is rotatably connected to the feeding body shell 4020 through a rotating driving member. A connecting column 404 is fixedly connected to the middle of the feeding body shell 4020, and the connecting column 404 passes through the electric feeding turntable 403, and a fixed connecting channel 405 is provided in the connecting column 404. A plurality of intermittent connecting channels 406 are opened on the electric feeding turntable 403, and the intermittent connecting channels 406 are used to cooperate with the fixed connecting channels 405.

[0060] A feed channel 407 and a discharge channel 408 are provided on the material adding main body shell 4020 , and a switch valve 409 is installed in the discharge channel 408 .

[0061] The working principle and beneficial effects of the above technical solution are as follows: when the feeding body 402 is working, the rotating driving member drives the electric feeding turntable 403 to rotate. During the rotation of the electric feeding turntable 403, when one of the intermittent connecting channels 406 is connected with the feeding channel 407, the sample to be measured in the feeding channel 407 fills the intermittent connecting channel 406 under the action of gravity, and then the intermittent connecting channel 406 continues to rotate forward under the action of the electric feeding turntable 403 until it is connected with the fixed connecting channel 405. When the intermittent connecting channel 406 is connected with the fixed connecting channel 405, the sample to be measured in the intermittent connecting channel 406 falls into the fixed connecting channel 405 under the action of gravity, and then flows into the discharge channel 408 along the fixed connecting channel 405 and the other intermittent connecting channel 406 in turn, and the sample to be measured is put into the sample holding container to be measured through the discharge channel 408;

[0062] The design of the feeding body 402 ensures the accurate feeding of a small amount of the sample to be measured, and does not cause sample contamination or squeeze the quality inspection balance, thereby ensuring the accuracy of the final test result;

[0063] When cleaning the intermittent connecting channel 406 and the fixed connecting channel 405 at the same time, after pouring the cleaning liquid into the feed funnel 400, the rotating driving part drives the electric feeding turntable 403 to rotate to achieve the cleaning of the inner walls of the intermittent connecting channel 406 and the fixed connecting channel 405. During the cleaning process, the centrifugal force ensures the final cleaning quality of the intermittent connecting channel 406 and the fixed connecting channel 405.

[0064] Example 7

[0065] On the basis of Example 1, the state control component 5 includes a connecting column 5000, which is fixedly connected to the bottom of the carrier 500, and a special-shaped clamping piece 501 is fixedly connected to the connecting column 5000. A measuring body 101 is provided in the balance body 1, and a special-shaped groove 102 is provided on the measuring body 101, and the special-shaped groove 102 is used to cooperate with the special-shaped clamping piece 501;

[0066] It also includes a carrier plate lifting control component, which is used to control the lifting of the carrier plate 500;

[0067] The loading plate lifting control assembly includes a storage slot 502, which is provided on the balance body 1, and an electric support rod 503 is rotatably connected in the storage slot 502;

[0068] A micro electric gear 504 is rotatably connected inside the carrier 500, and a micro rack 505 is slidably connected to the carrier 500 from left to right. The micro electric gear 504 and the micro rack 505 are meshed with each other. A guide block 506 is fixedly connected to the micro rack 505, and the guide block 506 is slidably connected in a slide groove 507. The guide block 506 and the slide groove 507 are connected by a connecting elastic member 508. A support rod accommodating groove 509 is provided on the carrier 500.

[0069] The working principle and beneficial effects of the above technical solution are as follows: before the quality inspection balance works, the special-shaped clamping piece 501 is located above the special-shaped slot 102, and the electric support rod 503 is in a vertical state, and the bottom of the micro-rack 505 is against the top of the electric support rod 503. At this time, no matter how the carrier plate 500 is squeezed, the quality inspection balance will not have a detection value;

[0070] When the quality inspection balance is working, the micro electric gear 504 rotates to drive the micro rack 505 to retract, so that the guide block 506 squeezes the connecting elastic member 508. In this process, the electric support rod 503 rotates from a vertical state to a horizontal state, and the carrier 500 falls under the action of gravity until the special-shaped clamping member 501 falls into the special-shaped groove 102. At this time, the carrier 500 is connected to the measuring body 101. When a sample is placed on the carrier 500, the quality inspection balance can detect the mass value;

[0071] If the balance is always in working state, the life and detection accuracy of the balance will be reduced. The design of the state control component 5 of the utility model ensures that the quality inspection balance will not be always in working state due to accidental touch or other reasons when it is not in working state, thereby extending the service life of the quality inspection balance and ensuring its detection accuracy.

[0072] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
