[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention allows operators to naturally release static electricity from their bodies upon contact with the metal handle during operation, effectively preventing fluctuations in measurement results due to neglecting to release static electricity. It also avoids interference from static electricity with the circuit system, ensuring the accuracy and stability of the measurement results. The platform dust cover and sliding shield door work together to form a closed space, significantly reducing the impact of external airflow and temperature / humidity fluctuations on the scale body, minimizing measurement deviations caused by external environmental factors, and improving measurement accuracy. The sliding shield door's opening and closing action, along with the position adjustment of the push plate and pressure guide plate, enables the automatic ejection of the drying bag and the collection of damp drying bags, continuously maintaining a dry environment within the closed space. This prevents moisture from corroding precision components such as sensors, extending the lifespan of the weighing platform. The closing shield door, when the sliding shield door is opened, covers the exposed drying bags, preventing them from absorbing moisture from the external environment and affecting their lifespan, thus reducing the frequency of drying bag replacement and lowering the workload for operators.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0024] Example 1: As attached Figure 1 To be continued Figure 2 As shown: This utility model provides a high-precision electronic scale weighing platform, including a platform body 1, a platform dust cover 2, a sliding shield door 3, a guide metal strip 4, a limiting structure, a metal screw 5, and a metal handle 6; the platform dust cover 2 is bolted to the upper part of the platform body 1; the sliding shield door 3 is slidably connected to the front side of the platform dust cover 2; the guide metal strip 4 is fixedly connected to the upper part of the platform body 1; the limiting structure is set on the upper part of the platform body 1; the metal screw 5 is threaded to the inner side of the guide metal strip 4; and the metal handle 6 is fixedly connected to the front side of the sliding shield door 3.

[0025] The limiting structure includes a guide storage box 201 and a connecting metal plate 601; the guide storage box 201 is bolted to the upper part of the platform dust cover 2; the connecting metal plate 601 is fixedly connected to the lower part of the metal handle 6, and the connecting metal plate 601 is slidably connected to the guide metal strip 4.

[0026] The limiting structure also includes a position adjustment push plate 301, a pressure guide plate 204, and a closing baffle plate 205; the position adjustment push plate 301 is hinged to the rear side of the sliding baffle door 3 by a torsion spring; the pressure guide plate 204 is slidably connected to the rear side of the guide storage box 201; and the closing baffle plate 205 is hinged to the rear side of the pressure guide plate 204 by a torsion spring.

[0027] The specific usage and function of this embodiment are as follows: When setting up the high-precision electronic scale, rotate the metal screw 5 to move it downwards along the guide metal strip 4 until it contacts the ground. Then, place multiple desiccant bags in the guide storage box 201. When using the weighing platform for weighing, first hold the metal handle 6 and push the sliding cover door 3 to the left. The connecting metal plate 601 remains in contact with the guide metal strip 4 during the sliding process. At this time, the metal handle 6, connecting metal plate 601, guide metal strip 4, and metal screw 5 will conduct static electricity. After opening the sliding cover door 3, the item to be weighed can be placed on top of the platform body 1 for weighing. After placing the item, close the sliding cover door 3. The sliding cover door 3 and the platform dust cover 2 form a closed space, reducing the influence of the external environment on the electronic scale. During the opening of the sliding cover door 3, the position adjustment push plate 301 will move. After the position adjustment push plate 301 contacts the pressure guide plate 204, it will push the pressure guide plate 204 and the sealing cover plate 205 to slide to the left along the guide storage box 201 to cover the outside of the exposed desiccant bag. After the pressure guide plate 204 moves to the maximum distance, the resistance of the position adjustment push plate 301 increases, causing the position adjustment push plate 301 to swing, so that the position adjustment push plate 301 can pass over the pressure guide plate 204. After the position adjustment push plate 301 passes over the pressure guide plate 204, the torsion spring will drive the position adjustment push plate 301 to return to its original position. During the closing of the sliding cover door 3, the position adjustment push plate 301 will push the pressure guide plate 204 in the opposite direction, so that the sealing cover plate 205 no longer blocks the outside of the desiccant bag.

[0028] Example 2: As attached Figure 1 To be continued Figure 7 As shown: Based on Embodiment 1, a transmission structure is also included; the transmission structure is located inside the platform dust cover 2.

[0029] The transmission structure includes a sliding push plate 202 and a limiting elastic element 203; the sliding push plate 202 is slidably connected to the inner side of the guide storage box 201; the sliding push plate 202 is elastically connected to the guide storage box 201 through the limiting elastic element 203.

[0030] The transmission structure also includes a replacement push plate 206 and a guide limiting shaft 207; the replacement push plate 206 is slidably connected to the left side of the guide storage box 201; the guide limiting shaft 207 is fixedly connected to the rear side of the replacement push plate 206.

[0031] The transmission structure also includes a limiting cam 208 and a dry bag collection box 212; the limiting cam 208 is rotatably connected to the left side of the guide storage box 201, and a guide groove is provided on the upper part of the limiting cam 208, which is slidably connected to the guide limiting shaft 207; the dry bag collection box 212 is bolted to the inside of the platform dust cover 2.

[0032] The transmission structure also includes a transmission gear 211 and a transmission tooth 302; the transmission gear 211 is rotatably connected to the left side of the guide storage box 201; the transmission tooth 302 is fixedly connected to the rear side of the sliding cover door 3.

[0033] The transmission structure also includes a direction-limiting pawl 209 and a direction-limiting ratchet 210; the direction-limiting pawl 209 is hinged to the lower part of the limiting cam 208; the direction-limiting ratchet 210 is fixedly connected to the inner side of the transmission gear 211, and the direction-limiting pawl 209 and the direction-limiting ratchet 210 together form a ratchet transmission structure.

[0034] The specific usage and function of this embodiment are as follows: During the opening of the sliding cover door 3, the transmission tooth 302 moves with the sliding cover door 3. After the transmission tooth 302 contacts the transmission gear 211, it pushes the transmission gear 211 to rotate a certain angle. At this time, the transmission gear 211 drives the direction limiting ratchet 210 to rotate. After the direction limiting pawl 209 is subjected to pressure, it swings inward and cannot drive the limiting cam 208 to rotate. During the closing of the sliding cover door 3, the transmission tooth 302 pushes the transmission gear 211 in the opposite direction. At this time, the direction limiting ratchet 210 will engage with the direction limiting pawl 209 and push the direction limiting pawl 209 to rotate. The rotation of the direction limiting pawl 209 will drive the limiting cam 208 to rotate. As the limiting cam 208 rotates, after the sliding cover door 3 is opened and closed multiple times, the protruding part of the guide groove of the limiting cam 208 moves below the guide limiting shaft 207. The guide groove causes the guide limiting shaft 207 and the replacement push plate 206 to move backward, pushing out the damp desiccant bag. At this time, the sealing cover plate 205 is squeezed by the desiccant bag and swings. After the desiccant bag falls into the desiccant bag collection box 212, the torsion spring will drive the sealing cover plate 205 to reset. The limiting cam 208 continues to move so that the protruding part of the guide groove passes over the guide limiting shaft 207, causing the replacement push plate 206 to reset. The limiting elastic element 203 will continue to push the sliding push plate 202, causing the sliding push plate 202 to push out the new desiccant bag.
