[0027] Embodiment:

[0028] Please refer to Figures 1 - 10, the present utility model provides a technical solution: a platform scale convenient for maintenance, including a lower scale frame 1 and an upper scale frame 2. The lower scale frame 1 and the upper scale frame 2 are fixedly connected by bolts. A protective seat 3 is fixedly connected to the inner side wall of the lower scale frame 1. A limiting frame 26 is fixedly connected to the inner side wall of the upper scale frame 2. The limiting frame 26 is located directly above the protective seat 3. A weighing sensor 4 is arranged on the limiting frame 26. The bottom of the weighing sensor 4 is located inside the protective seat 3. A scale pan 5 is arranged on the upper scale frame 2. The upper scale frame 2 and the scale pan 5 are detachably connected through a connecting component, which is convenient to disassemble the platform scale and repair and maintain its components. The weighing sensor 4 and the weighing instrument 24 are electrically connected through wiring for signal transmission. A damping rotating shaft design is adopted between the weighing instrument 24 and the fixed seat 23, allowing users to adjust the use angle of the weighing instrument 24 according to needs, improving comfort. The weighing sensor 4 is fixedly installed on the limiting frame 26 by bolts and is protected by the protective seat 3, improving the durability of the weighing sensor 4;

[0029] The connecting component includes a positioning plate 10 fixedly connected to the top of the inner wall of the scale pan 5. A circular groove 11 is opened on the inner wall of the positioning plate 10. A telescopic rod 12 is fixedly connected to the inner wall of the circular groove 11. One end of the telescopic rod 12 away from the circular groove 11 is fixedly connected with a clamping block 14. A spring 13 is fixedly connected to the inner wall of the circular groove 11. One end of the spring 13 away from the circular groove 11 is fixedly connected to the outer wall of the clamping block 14. A slot 9 is opened on the inner wall of the upper scale frame 2. The positioning plate 10 is inserted into the slot 9;

[0030] A rectangular opening 27 is opened on the inner wall of the upper scale frame 2. The rectangular opening 27 communicates with the slot 9. Grooves 17 are symmetrically opened on the inner wall of the upper scale frame 2. The grooves 17 are located outside the rectangular opening 27. A limiting block 18 abuts against the inner wall of the rectangular opening 27. A screw hole 16 is opened on the top of the lower scale frame 1. The bottom end of the limiting block 18 is rotatably connected with a screw rod 28. The screw rod 28 is threadedly connected with the screw hole 16. Protrusions 19 are symmetrically connected to the outer wall of the limiting block 18. The protrusions 19 abut against the inner wall of the grooves 17. A clamping hole 20 is opened on the inner wall of the limiting block 18. The clamping block 14 is clamped with the inner wall of the clamping hole 20. A clamping groove 15 is opened on the outer wall of the scale pan 5. The clamping groove 15 is located outside the positioning plate 10. The clamping block 14 is clamped with the clamping groove 15;

[0031] Before the lower weighing frame 1 and the upper weighing frame 2 are fixed together, first fix and install the limit block 18 on the lower weighing frame 1 through the screw rod 28. After the lower weighing frame 1 and the upper weighing frame 2 are fixed as a whole, rotate the limit block 18 so that it snaps into the rectangular opening 27 to play a limiting role. When installing the weighing pan 5 on the upper weighing frame 2, press the clamping block 14 to compress the spring 13, then insert the positioning plate 10 into the slot 9 and release the hand. When the clamping block 14 passes through the clamping hole 20, under the reaction force of the spring 13, it snaps into the clamping hole 20, and the front end snaps into the inside of the clamping groove 15, and the installation can be completed. This disassembly and assembly method is simple and convenient to disassemble the weighing pan 5 of the platform scale for maintenance and repair of its components.

[0032] The inner wall of the weighing pan 5 is fixedly connected with an insertion shaft 7. A lower insertion hole 8 is opened on the lower weighing frame 1, and an upper insertion hole 6 is opened on the upper weighing frame 2. The bottom end of the insertion shaft 7 passes through the upper insertion hole 6 and is inserted into the inner wall of the lower insertion hole 8. When installing the weighing pan 5, by passing the insertion shaft 7 through the upper insertion hole 6 and inserting it into the lower insertion hole 8, it plays a limiting role to prevent the weighing pan 5 from loosening during installation and improves the stability of the installation of the weighing pan 5.

[0033] The top of the lower weighing frame 1 is fixedly connected with a vertical rod 22. The top of the vertical rod 22 is fixedly connected with a fixed seat 23. A weighing instrument 24 is rotatably connected to the fixed seat 23. Through the weighing instrument 24, it is convenient to convert the signal of the weighing sensor 4 into a weight number for display, which is convenient for the operator to view.

[0034] The bottom end of the lower weighing frame 1 is fixedly connected with weighing feet 21. The bottom surface of the weighing feet 21 is bonded with anti-slip rubber pads. The weighing feet 21 are used to support the lower weighing frame 1, and the anti-slip rubber pads are used to improve the anti-slip property of its bottom.

[0035] The inner wall of the lower weighing frame 1 is fixedly connected with a support plate 25. The top surface of the support plate 25 is fixedly connected with the bottom surface of the protection seat 3. The support plate 25 provides support for the protection seat 3 and enhances the strength of the protection seat 3.

[0036] Working principle: A detachable connection is achieved between the upper weighing frame 2 and the weighing pan 5 through a connecting component, which facilitates disassembling the platform scale to repair and maintain its components. The weighing sensor 4 and the weighing instrument 24 are electrically connected through wiring for signal transmission. A damping rotating shaft design is adopted between the weighing instrument 24 and the fixed seat 23, allowing users to adjust the use angle of the weighing instrument 24 as needed to improve comfort. The signal of the weighing sensor 4 is conveniently converted into a weight number and displayed through the weighing instrument 24 for easy viewing by the operator. The weighing sensor 4 is fixedly installed on the limit frame 26 through bolts and is protected by the protective seat 3 to improve its durability. Before the lower weighing frame 1 and the upper weighing frame 2 are fixed together, the limit block 18 is first fixedly installed on the lower weighing frame 1 through the screw 28. After the lower weighing frame 1 and the upper weighing frame 2 are fixed into one body, the limit block 18 is rotated to make it snap into the rectangular opening 27 to play a limiting role. When the weighing pan 5 is installed on the upper weighing frame 2, the spring 13 is compressed by pressing the clamping block 14, and then the positioning plate 10 is inserted into the slot 9 and released. When the clamping block 14 passes through the clamping hole 20, under the reaction force of the spring 13, it snaps into the clamping hole 20 and the front end snaps into the inside of the clamping groove 15, thus completing the installation. This disassembly and assembly method is simple and convenient for disassembling and assembling the weighing pan 5 of the platform scale. When the weighing pan 5 is installed, the insertion shaft 7 passes through the upper insertion hole 6 and is inserted into the lower insertion hole 8 to play a limiting role, preventing the weighing pan 5 from being loosely installed and improving the installation stability of the weighing pan 5.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
