DETAILED DESCRIPTION

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0022] Reference Figure 1 - Figure 3 As shown, the utility model provides a technical solution: a weighing device with a precision weighing function, comprising a weighing device body 1, a weighing unit 2 is installed on the top of the weighing device body 1, connecting plates 3 are installed on both sides of the weighing device body 1, a fixing rod 4 is installed at the bottom end of the connecting plate 3, an adjusting rod 5 is slidably connected to the inside of the fixing rod 4, a fixing suction cup 6 is installed at the bottom end of the adjusting rod 5, a pressing groove 7 is opened on one side of the adjusting rod 5, an elastic spring 8 is installed inside the pressing groove 7, two ejection ports 9 are opened on one side of the fixing rod 4, and the pressing The groove 7 and the ejection port 9 are both slidably connected to a pressing block 10, and one end of the elastic spring 8 close to the pressing block 10 is fixedly connected to the pressing block 10. When the weighing device body 1 is in use, the pressing block 10 is pressed inward to store force in the elastic spring 8, and at the same time, the adjusting rod 5 is released from the limit. At this time, the fixed suction cup 6 is moved to a position close to the ground to fix it on the ground, so that the weighing device body 1 will not move due to external touch or vibration of the machine during use, thereby improving the accuracy of the weighing device body 1 during weighing.

[0023] Reference Figure 3 As shown, in this embodiment: the front end and the rear end of the pressing groove 7 are both provided with a first sliding groove 11, the front end and the rear end of the pressing block 10 are both fixedly connected with a first slider 12, and the interior of the first sliding groove 11 is slidingly connected to the first slider 12. Through the setting of the first sliding groove 11 and the first slider 12, the ejection outlet 9 will not eject too much and fall off during the ejection process, thereby improving the stability of the device when in use.

[0024] Reference Figure 4 As shown, in this embodiment: the front end and the rear end inside the fixed rod 4 are both provided with a second sliding groove 13, the front end and the rear end of the adjusting rod 5 are both fixedly connected with a second slider 14, and the interior of the second sliding groove 13 is slidably connected to the second slider 14. Through the setting of the second sliding groove 13 and the second slider 14, the adjusting rod 5 can form a stable guiding effect when moving inside the fixed rod 4, preventing the pressing block 10 from being unable to pop out into the ejection outlet 9 due to offset, affecting the fixation of the adjusting rod 5 after adjustment.

[0025] Reference Figure 4As shown, in this embodiment: the top end of the adjusting rod 5 is fixedly connected with a return spring 15, and the top end of the return spring 15 is fixedly connected to the inside of the fixed rod 4. Through the setting of the return spring 15, when the adjusting rod 5 and the fixed suction cup 6 are released from the limit, the tension of the return spring 15 drives the adjusting rod 5 to be quickly pulled back to the inside of the fixed rod 4, so that the adjusting rod 5 can be easily reset, which is convenient for the staff to use next time.

[0026] Reference Figure 5 As shown, in this embodiment: an opening 16 is opened inside the fixed suction cup 6, an air outlet 17 is installed at the top of the opening 16, and a sealing plate 18 is installed inside the air outlet 17. When the staff needs to release the limit between the fixed suction cup 6 and the desktop, the sealing plate 18 is opened. At this time, the pressure inside the fixed suction cup 6 causes the air to quickly enter the interior of the fixed suction cup 6 from the air outlet 17, so that the fixed suction cup 6 and the desktop are quickly released.

[0027] Reference Figure 2 As shown, in this embodiment: the surface of the pressing block 10 is provided with a rounded corner 19. Through the setting of the rounded corner 19, the fixed suction cup 6 can be retracted by only pushing the adjusting rod 5 during the retraction process, without pressing the pressing block 10 again.

[0028] Reference Figure 1 As shown, in this embodiment: the weighing unit 2 uses a dual-sensor design. Through the dual-sensor design, the material weight feedback can have an additional signal, further improving the weighing accuracy and stability.

[0029] Working principle: When the weighing device body 1 is in use, the pressing block 10 is pressed inward to store the elastic spring 8 and release the limit of the adjusting rod 5. At this time, the fixed suction cup 6 is moved to a position close to the ground to fix it on the ground, so that the weighing device body 1 will not move due to external touch or vibration of the machine during use, thereby improving the accuracy of the weighing device body 1 during weighing. By setting the first slide 11 and the first slider 12, the ejection outlet 9 will not pop out too much during the ejection process and cause it to fall off, thereby improving the stability of the device during use. By setting the second slide 13 and the second slider 14, the adjusting rod 5 can form a stable guiding effect when moving inside the fixed rod 4, thereby preventing the pressing block 10 from being unable to pop out into the ejection outlet 9 due to deviation. After the adjusting rod 5 is adjusted, it is fixed. Through the setting of the reset spring 15, when the adjusting rod 5 and the fixed suction cup 6 are released from the limit, the tension of the reset spring 15 drives the adjusting rod 5 to be quickly pulled back to the inside of the fixed rod 4, so that the adjusting rod 5 is conveniently reset, which is convenient for the staff to use next time. When the staff needs to release the limit of the fixed suction cup 6 from the desktop, the sealing plate 18 is opened. At this time, the pressure inside the fixed suction cup 6 causes the air to quickly enter the inside of the fixed suction cup 6 from the air outlet 17, so that the fixed suction cup 6 and the desktop are quickly released from the limit. Through the setting of the rounded corners 19, the fixed suction cup 6 only needs to push the adjusting rod 5 to retract the fixed suction cup 6 during the retraction process, and there is no need to press the pressing block 10 again. Through the design of dual sensors, the material weight feedback can have an additional signal, further improving the accuracy and stability of weighing.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
