Description

Technical Field

[0001] This utility model relates to the technical field of electronic balances, and in particular to a high-precision electronic balance. Background Technology

[0002] An electronic balance is a measuring instrument that determines the mass of an object by the force of gravity acting on it and outputs the result digitally.

[0003] Electronic balances generally employ strain gauge sensors, capacitive sensors, and electromagnetic balance sensors. Strain gauge sensors are simple in structure and low in cost, but their accuracy is limited. During use, the presence of external uncertainties can affect the measurement structure of the electronic balance. In related technologies, by setting telescopic support legs and a level bubble, and by observing the position of the level bubble and adjusting the length of each telescopic support leg, the main body of the electronic balance can be adjusted to be level, thereby improving the accuracy of the electronic balance.

[0004] However, in actual use, the height of multiple support legs needs to be adjusted sequentially, resulting in low adjustment efficiency, certain limitations, and inconvenience in use. Utility Model Content

[0031] In use, this invention involves rotating the adjusting rod to slide the fixing block out of the groove, then manually pushing or pulling the edge of the electronic balance body to adjust its level. After adjustment, the adjusting rod is rotated counterclockwise to insert the fixing block into the groove and press it against the second support leg inside the first support leg.

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0043] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0044] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly.

[0045] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0046] Electronic balances use strain gauge sensors, capacitive sensors, and electromagnetic balance sensors to measure the weight of items. Strain gauge sensors are simple in structure and low in cost, but their accuracy is limited. When in use, the presence of external uncertainties can have a certain impact on the measurement structure of the electronic balance.

[0047] In related technologies, by setting telescopic support legs and a horizontal bubble, and by observing the position of the horizontal bubble and adjusting the length of each telescopic support leg, the main body of the electronic balance can be adjusted to be horizontal, thereby improving the accuracy of the electronic balance. However, in actual use, the height of multiple support legs needs to be adjusted sequentially, resulting in low adjustment efficiency, certain limitations, and inconvenience in use.

[0048] To address some of the problems in the related technologies, this application provides a high-precision electronic balance. When needed, the balance body 10 can be manually adjusted to a horizontal state, and the adjustment rod 20 can be rotated to lock the level of the balance body 10. This is more convenient and faster, improving the usability of the device.

[0049] This application is described below with reference to the accompanying drawings and specific embodiments:

[0050] Combination Figures 1-4This application provides a high-precision electronic balance, comprising: an electronic balance body 10, with a cover 11 on its top; a first support leg 12, fixedly connected to the bottom of the electronic balance body 10; a second support leg 13, slidably connected to the first support leg 12; an adjusting rod 20, rotatably connected to the bottom of the electronic balance body 10; a transmission mechanism 21, disposed at the bottom of the electronic balance body 10; a slider 22, slidably connected to the bottom of the electronic balance body 10, the transmission mechanism 21 being used to adjust the position of the slider 22; a fixing block 23, fixedly connected to the side of the slider 22; a groove 24, formed on the outside of the first support leg 12, the fixing block 23 being inserted into the groove 24; a ball 25, fixedly connected to one end of the second support leg 13; and a pad 26, fitted onto the outside of the ball 25.

[0051] After placing the electronic balance body 10 in the designated position, the pad 26 directly contacts the surface of the object, providing support for the electronic balance body 10. Then, open the cover 11 on the electronic balance body 10, place the item to be weighed on the electronic balance body 10, and then close the cover 11 to perform the weighing operation. Before weighing, if the level of the electronic balance body 10 needs to be adjusted, turn the adjusting rod 20 clockwise to slide the two sliders 22 toward opposite faces, thereby causing the fixing block 23 to slide out of the groove 24. Then, manually push or pull the edge of the electronic balance body 10 to adjust the level. The level of the balance body 10 is adjusted by sliding the second support foot 13 out of the first support foot 12 or sliding the second support foot 13 into the first support foot 12. After the adjustment is completed, the adjusting rod 20 is rotated counterclockwise so that the adjusting rod 20 adjusts the position of the two sliders 22 through the transmission mechanism 21, so that the two sliders 22 slide towards each other. This causes the two sliders 22 to drive the fixing block 23 to insert into the groove 24 and press against the second support foot 13 in the first support foot 12. After the height of the multiple second support feet 13 is squeezed and limited, the adjustment is completed. At this time, the above steps are repeated to weigh the weight.

[0052] During adjustment, the pad 26 is rotated outside the ball 25 so that the pad 26 is always in direct contact with the load surface, thereby improving stability.

[0053] Specifically, the electronic balance body 10 uses the electromagnetic force balance principle for weighing. It achieves high-precision measurement by balancing the electromagnetic force generated by the current with the weight of the object being weighed. This is existing technology and will not be elaborated further.

[0054] Optionally, multiple adjusting rods 20 are provided. Rotating any one of the adjusting rods 20 can adjust the position of the slider 22, which is convenient for subsequent fixing.

[0055] Optionally, the transmission mechanism 21 includes: a fixed base 211, fixedly connected to the bottom of the electronic balance body 10; a bidirectional threaded rod 212, rotatably connected to the fixed base 211; a housing 213, fixedly connected to the bottom of the electronic balance body 10, with the bidirectional threaded rod 212 passing through the housing 213; a bevel gear 214, fixedly connected to one end of the adjusting rod 20 and the outside of the bidirectional threaded rod 212, with the two bevel gears 214 meshing with each other; and the slider 22 being threadedly connected to the bidirectional threaded rod 212.

[0056] When the adjusting rod 20 is rotated, it drives one bevel gear 214 to rotate. At the same time, through meshing with another bevel gear 214, the other bevel gear 214 drives the bidirectional threaded rod 212 to rotate. Then, through the threaded connection between the bidirectional threaded rod 212 and the slider 22, the slider 22 is limited.

[0057] Specifically, a limit rod is fixedly connected between the two fixed seats 211, so that the slider 22 can only slide left and right (direction reference). Figure 3 ).

[0058] Optionally, the slider 22 is provided with multiple fixing blocks 23, so that when the slider 22 slides, it drives the multiple fixing blocks 23 to be inserted into multiple slots 24 respectively, thereby limiting the height of the multiple support legs 13.

[0059] Optionally, a level 27 is provided on the top of the electronic balance body 10. While manually pushing or pulling the electronic balance body 10, the operator can observe the level 27 to determine whether the electronic balance body 10 is in a horizontal state, thereby improving its practicality.

[0060] Optionally, a groove 30 is formed inside the first support leg 12; a ring 31 is fixedly connected to the outside of the second support leg 13, and the ring 31 is slidably connected inside the groove 30; a spring 32 is disposed inside the groove 30, and the ring 31 is connected to the first support leg 12 through the spring 32.

[0061] When the electronic balance body 10 is manually pushed or pulled, the second support foot 13 slides into the first support foot 12, and the second support foot 13 drives the ring 31 to slide in the slide groove 30, and squeezes the spring 32, so as to provide resistance when changing the angle of the electronic balance body 10, thereby making the adjustment more precise.

[0062] Optionally, multiple springs 32 are provided, and multiple springs 32 work simultaneously to make the ring 31 subjected to uniform force, thereby making its sliding more stable.

[0063] Optionally, the length of the second support leg 13 is greater than the length of the first support leg 12, so that the second support leg 13 can slide up and down within the first support leg 12.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
