[0023] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0024] like Figure 1-Figure 5 ;

[0025] A moisture-proof and dust-proof sealing cover structure for a weighing cash register scale includes a scale body 1, the scale body 1 model is GS-G5, a support frame 11 is installed at the rear end of the scale body 1, the support frame 11 is used to support and install a cash register screen 12, and the top of the support frame 11 is hinged to the cash register screen 12;

[0026] The rear end of the support frame 11 is provided with a sealing mechanism 2, which can seal the cover of the weighing cashier scale against moisture and dust;

[0027] The sealing mechanism 2 includes a connecting assembly 3 and a cover assembly 4. The connecting assembly 3 is installed inside the rear end of the support frame 11. The connecting assembly 3 is used to cooperate with the cover assembly 4 to be sealed and connected to the rear end of the support frame 11. The cover assembly 4 and the connecting assembly 3 are connected. The cover assembly 4 is easy to open and has good sealing performance.

[0028] Furthermore, the connecting component 3 includes an opening 31 and a single-chip computer 32. The opening 31 is opened at the rear end of the support frame 11. The single-chip computer 32 is conveniently installed and symmetrically arranged through the opening 31. The single-chip computer 32 is installed inside the support frame 11 through the opening 31. The model of the single-chip computer 32 is HX711. A card slot 33 is installed on the inner side of the opening 31. The card slot 33 is not only used for placing the filter cotton 34, but also for clamping the card strip 42 and the sealing strip 43, so as to position and install the cover plate 41. The filter cotton 34 is laid on the inner side of the card slot 33. The filter cotton 34 can absorb moisture. The filter cotton 34 not only increases the sealing of the cover plate 41 after installation, but also increases the moisture-proof and dust-proof properties of the cover plate 41. A connector 35 connected to the cover plate assembly 4 is installed on the single-chip computer 32 by screws. The connector 35 is used to be connected to the bolts on the cover plate 41, so as to stably connect the cover plate 41.

[0029] Furthermore, the cover assembly 4 includes a cover 41, a card strip 42 and a sealing strip 43. The cover 41 is installed at the rear end of the support frame 11 to seal the opening 31 and to seal the interior of the support frame 11 against moisture and dust to prevent the internal single-chip computer 32 from being affected. A card strip 42 is installed on the inner side of the cover 41. The card strip 42 and the sealing strip 43 are connected to the card slot 33 to increase the sealing performance of the cover 41. The sealing strip 43 is installed on the end of the card strip 42 away from the cover 41. The sealing strip 43 will contact the filter cotton 34. The card strip 42 and the sealing strip 43 are both inserted into the card slot 33 to seal the inside of the card slot 33. A rubber strip 44 is also installed on the inner side of the cover 41. The rubber strip 44 is inserted into the The cover 41 is inserted into the inner side of the card slot 33 and fits tightly. The sealing of the cover 41 is further increased by the rubber strip 44, as well as the stability and portability of the cover 41. A socket 46 for mounting bolts is provided on the top of the cover 41. Bolts are inserted into the socket 46 and the bolts are connected to the connector 35, thereby fixing the cover 41 to the rear end of the support frame 11. An insert block 45 and a pull block 47 for pulling the cover 41 are respectively installed at the bottom of the cover 41. The insert block 45 is inserted into the bottom of the opening 31. When installing the cover 41, the insert block 45 is inserted first, and then the card strip 42 and the sealing strip 43 are plugged and installed, so that the cover 41 is easy to align during installation. Fingers are inserted into the pull block 47 to facilitate pulling the cover 41 open.

[0030] The working principle of the present invention is as follows: first insert the insert block 45 so that the cover plate 41 is aligned and snapped into the opening 31, and the filter cotton 34 is laid on the inner side of the card slot 33. The filter cotton 34 can absorb moisture, and the filter cotton 34 not only increases the sealing of the cover plate 41 after installation, but also increases the moisture and dust resistance of the cover plate 41. The card strip 42 and the sealing strip 43 are both inserted into the inside of the card slot 33 to seal the inside of the card slot 33 to increase the sealing of the cover plate 41 installation and seal the interior of the support frame 11 against moisture and dust to prevent the internal single-chip computer 32 from being affected. A rubber strip 44 is also installed on the inner side of the cover plate 41. The rubber strip 44 is inserted into the inner side of the card slot 33 and fits tightly. The rubber strip 44 further increases the sealing of the cover plate 41 installation, as well as the stability and portability of the cover plate 41 installation, so that the cover plate behind the weighing cash register scale is not only convenient to remove and install, but also has good sealing, and the interior of the weighing cash register scale is sealed against moisture and dust.
