Description

Technical Field

[0001] This utility model belongs to the field of electronic weighing instrument technology, and more specifically, relates to an electronic weighing instrument with an anti-corrosion structure. Background Technology

[0002] Electronic weighing instruments are widely used in factories, mines, ports, warehouses, docks and other industries for weighing and measuring various materials. Electronic weighing instruments consist of a weighing plate, support legs and weighing sensors. When using an electronic weighing instrument, workers place the object to be weighed on the weighing plate. Due to the weight of the object, the weighing sensor is deformed by the force, and the generated signal is processed by the central microprocessor and finally displayed digitally on the display.

[0003] The inventors discovered in their daily work that when using electronic scales, the objects being weighed may have sharp edges, which could scratch the weighing plate of the scale, thereby damaging the anti-corrosion layer coated on the weighing plate. Some electronic scales are used outdoors for extended periods, which may allow rainwater to corrode the damaged anti-corrosion layer on the weighing plate, potentially affecting the use of the electronic scale. Utility Model Content

[0004] The main purpose of this invention is to provide an electronic weighing instrument with a corrosion-resistant structure.

[0005] According to a first aspect of the present invention, an electronic weighing instrument with a corrosion-resistant structure is provided, including a weighing plate, a support foot provided at the lower end of the weighing plate, a weighing sensor installed between the support foot and the weighing plate, a protective component provided at the lower end of the weighing plate, and a corrosion-resistant component provided at the upper end of the weighing plate. The corrosion-resistant component includes a first protective plate and a second protective plate provided at the upper end of the weighing plate. A fixing rod is fixedly connected to the side of the second protective plate near the first protective plate. The fixing rod is inserted into the first protective plate, and a protrusion is provided on the arc surface of the fixing rod.

[0006] By setting up anti-corrosion components, workers can prevent sharp objects from scratching the electronic scale. They drag the first and second protective plates so that the fixing rod is inserted into the first protective plate and fixed to the weighing plate. The first and second protective plates then protect the weighing plate, so that sharp objects will not scratch the weighing plate, thus minimizing the risk of scratching the weighing plate.

[0007] According to the first aspect of the present invention, an electronic weighing instrument with a corrosion-resistant structure has positioning rods slidably connected to both sides of the inner wall of the first protective plate, and the positioning rods are inserted into the fixing rods. After the fixing rod is inserted into the first protective plate, the positioning rods are inserted into the fixing rods, thereby further fixing the first and second protective plates together.

[0008] According to the first aspect of the present invention, an electronic weighing instrument with an anti-corrosion structure is provided, in which a first spring is fixedly connected between the two positioning rods, and the first spring is located inside a first protective plate. The positioning rods are reset by the first spring.

[0009] According to the first aspect of the present invention, an electronic weighing instrument with an anti-corrosion structure is provided, in which a pull rope is fixedly connected between the two positioning rods, and the pull rope passes through a first protective plate. Pulling the pull rope completely separates the positioning rod from the fixed rod, allowing the worker to drag the first protective plate for disassembly.

[0010] According to the electronic weighing instrument with an anti-corrosion structure described in the first aspect embodiment of this utility model, rubber gaskets are fixedly connected to the inner walls of the first and second protective plates. The rubber gaskets assist in fixing the first and second protective plates together.

[0011] According to the first aspect of the present invention, the electronic weighing instrument with an anti-corrosion structure includes a protective cover fixedly connected to the lower end of the weighing plate, a load cell located inside the protective cover, and a sealing gasket fixedly connected to the inner wall of the protective cover. When corrosion protection of the load cell is required, the load cell is sealed by setting the protective cover and the sealing gasket to prevent rainwater from corroding the load cell.

[0012] According to the first aspect of the present invention, an electronic weighing instrument with a corrosion-resistant structure has a sealing block slidably connected to the inner wall of the support leg, and the sealing block is inserted into the sealing gasket. By providing the sealing block, the sealing gasket is assisted in sealing the weighing sensor.

[0013] According to the first aspect of the present invention, in the electronic weighing instrument with an anti-corrosion structure, a second spring is fixedly connected to the upper end of the sealing block, and the other end of the second spring is fixed to the support leg. By providing the second spring, the sealing block is kept in full contact with the sealing gasket when the weighing sensor deforms during weighing.

[0014] One of the above-described technical solutions of this utility model has at least one of the following advantages or beneficial effects:

[0015] In this invention, by setting up anti-corrosion components, to prevent sharp-edged objects from scratching the electronic weighing instrument, the worker drags the first and second protective plates, causing the fixing rod to insert into the first protective plate and thus fix it to the weighing plate. The first and second protective plates then protect the weighing plate, preventing sharp-edged objects from scratching it. This solves the problem that sharp-edged objects may scratch the weighing plate, damaging the anti-corrosion layer. Furthermore, some electronic weighing instruments operate outdoors for extended periods, where rainwater may corrode the damaged anti-corrosion layer, potentially affecting the instrument's usability.

[0028] Reference Figure 2 and Figure 3 As shown, in some embodiments of this utility model, the anti-corrosion component 2 includes a first protective plate 21 and a second protective plate 22 disposed on the upper end of the weighing plate 1. A fixing rod 23 is fixedly connected to the side of the second protective plate 22 near the first protective plate 21. The fixing rod 23 is inserted into the first protective plate 21, and the arc surface of the fixing rod 23 is provided with a protrusion. By setting the anti-corrosion component 2, when preventing sharp objects from scratching the electronic weighing instrument, the worker drags the first protective plate 21 and the second protective plate 22, so that the fixing rod 23 is inserted into the first protective plate 21 and thus fixed to the weighing plate 1. Then, the first protective plate 21 and the second protective plate 22 protect the weighing plate 1, so that sharp objects will not scratch the weighing plate 1, thereby achieving the effect of avoiding scratches on the weighing plate 1 as much as possible.

[0029] In some embodiments of this utility model, positioning rods 24 are slidably connected to both sides of the inner wall of the first protective plate 21. The positioning rods 24 are inserted into the fixing rods 23.

A sealing block 33 is slidably connected to the inner wall of the support foot 4. The sealing block 33 is inserted into the sealing gasket 32. By setting the sealing block 33, the sealing gasket 32 ​​is assisted in sealing the weighing sensor 5. A second spring 34 is fixedly connected to the upper end of the sealing block 33. The other end of the second spring 34 is fixed to the support foot 4. By setting the second spring 34, the sealing block 33 is kept in full contact with the sealing gasket 32 ​​when the weighing sensor 5 deforms during weighing.

[0031] The worker places the object to be weighed onto the weighing plate 1. Due to the weight of the object, the load cell 5 on the support leg 4 (the specific usage of the load cell 5 is a commercially available product and will not be elaborated here) is deformed by the force. The generated signal is processed by the central microprocessor and finally displayed digitally on the monitor. To prevent sharp objects from scratching the electronic scale, the worker drags the first protective plate 21 and the second protective plate 22, so that the fixing rod 23 is inserted into the first protective plate 21 and fixed to the weighing plate 1. Then, the first protective plate 21 and the second protective plate 22 protect the weighing plate 1, so that sharp objects will not scratch the weighing plate 1, thereby achieving the effect of avoiding scratches on the weighing plate 1 as much as possible.

[0032] After the fixing rod 23 is inserted into the first protective plate 21, the positioning rod 24 is inserted into the fixing rod 23, thereby further fixing the first protective plate 21 and the second protective plate 22.

When it is necessary to prevent corrosion of the weighing sensor 5, the weighing sensor 5 is sealed by setting the protective cover 31 and the sealing gasket 32 ​​to prevent rainwater from corroding the weighing sensor 5. The sealing block 33 is set to assist the sealing gasket 32 ​​in sealing the weighing sensor 5. The second spring 34 is set to keep the sealing block 33 in full contact with the sealing gasket 32 ​​when the weighing sensor 5 deforms during weighing.
