Description

Technical Field

[0001] This utility model relates to the field of electronic balance technology, specifically to an electronic balance with built-in calibration device. Background Technology

[0002] Electronic balances, as precision weighing instruments, are now widely used. Calibration of electronic balances can be divided into internal calibration and external calibration. "Internal calibration" refers to calibration using the calibration weights installed inside the electronic balance and following the internal standard procedure. During calibration, simply press the calibration button, and the motor will drive the lifting device with built-in weights to load the balance, thereby implementing and completing the calibration.

[0003] A search revealed a utility model patent in China with patent publication number CN213812566U, which discloses a built-in calibration device for an electronic balance. The device generally includes a fixed frame; a lifting frame suitable for supporting weights, with a groove on its back and a block extending horizontally forward from the top of the groove; and a weight support located below the lifting frame. During use, the motor is positioned in the middle of the back of the fixed frame, thus shortening the width of the built-in calibration device, optimizing the component layout, and reducing the overall footprint. However, this device still has some shortcomings. For example, the fixed frame is secured to the electronic balance using multiple screws, requiring personnel to carry appropriate tools for installation and removal during maintenance or replacement. If appropriate tools are unavailable or lost, installation and removal become inconvenient and time-consuming. Therefore, we propose a built-in calibration device for an electronic balance.

[0025] Example

[0026] Please see Figures 1-4 An electronic balance with a built-in calibration device includes a calibration mechanism 1, comprising:

[0027] Fixture 2;

[0028] The mounting mechanism is set on the fixed base 2 and the calibration mechanism 1, and is used to mount the calibration mechanism 1 on the fixed base 2;

[0029] The reinforcement mechanism is installed on the fixing base 2 and the calibration mechanism 1 to improve the stability of the fixation.

[0030] Preferably, the installation mechanism includes two mounting slots 3 and two mounting plates 4. Both mounting slots 3 are fixedly connected to the fixed base 2, and both mounting plates 4 are fixedly connected to the calibration mechanism 1. Each mounting plate 4 has a limiting port 5. The mounting plate 4 is located inside the mounting slot 3. The mounting slot 3 has two positioning slots 6. A tension spring 7 is fixedly connected inside the positioning slot 6. A lifting plate 8 is fixedly connected to the two tension springs 7. A limiting block 9 is fixedly connected to the lifting plate 8. The mounting slot 3 has a second limiting port. The limiting block 9 is located inside the second limiting port and the first limiting port 5. The mounting plate 4 is placed inside the mounting slot 3, and the limiting block 9 is locked inside the first limiting port 5 and the second limiting port to limit the mounting plate 4. The tension spring 7 provides tension to ensure the stability of the position of the limiting block 9. This allows the calibration mechanism 1 to be installed without the use of tools.

[0031] The reinforcement mechanism includes a groove 10, two slides 11, and two mounting blocks 12. The groove 10 and the two slides 11 are all formed on the fixed base 2. The two slides 11 are connected to the groove 10. The two mounting blocks 12 are fixedly connected to the calibration mechanism 1. The mounting blocks 12 are provided with a bayonet 13. A slider 14 is slidably connected in the slide 11. A bidirectional screw 15 is rotatably connected between the two slides 11. The two sliders 14 are threadedly connected to the bidirectional screw 15. A control ring 16 is fixedly sleeved on the bidirectional screw 15. A locking block 17 is fixedly connected to the slider 14. The locking block 17 is located in the bayonet 13. The fixed ring is used to rotate the bidirectional screw 15. The bidirectional screw 15 is used to move the slider 14 and the locking block 17. The locking block 17 is used to lock in the bayonet 13 to further improve the stability and firmness of the calibration mechanism 1.

[0032] A stabilizing rod 18 is fixedly connected inside the positioning groove 6, and the lifting plate 8 is slidably connected to the two stabilizing rods 18 to improve the stability of the lifting plate 8 and the tension spring 7.

[0033] A pull ring 19 is fixedly connected to the lifting plate 8 for easy lifting of the lifting plate 8.

[0034] The fixed base 2 has two limiting grooves 20. One end of the limiting block 9 is located in the limiting groove 20, so that the limiting block 9 goes deep into the limiting groove 20 and better locks the limiting port 2.

[0035] In summary, the working principle and process of the built-in calibration device of the electronic balance are as follows: First, place the built-in calibration device at the desired location and fix the mounting base 2 to the electronic balance. Then, move the calibration mechanism 1 next to the mounting base 2 and slide the mounting plate 4 on the calibration mechanism 1 to the inlet of the mounting groove 3. At this time, pull the pull ring 19 with your finger. The pull ring 19 drives the lifting plate 8 and the limiting block 9 to move, and the tension spring 7 will be stretched. After the limiting block 9 moves out of the limiting groove 20, it moves into the limiting port 2. At this time, the mounting plate 4 can be completely sent into the mounting groove 3. Release the pull ring 19, and the tension spring 7 tightens, causing the lifting plate 8 and the limiting block 9 to descend. The limiting block 9 enters the limiting port 5 and the limiting groove 20, thus fixing the mounting plate 4. In this way, it is fixed. The calibration mechanism 1 is calibrated by rotating the bidirectional screw 15 through the fixing ring. The bidirectional screw 15 drives the two sliders 14 to move away from each other, so that the sliders 14 drive the locking block 17 to move into the locking slot 13, thereby limiting and fixing the mounting block 12. This completes the installation of the calibration mechanism 1. The device is simple and quick to operate, improving its practicality. The calibration mechanism 1 involved in this solution is the authorized technology disclosed in the utility model patent with Chinese Patent Publication (Announcement) No. CN213812566U. Its internal structure and working principle are well known to those skilled in the art and are not the innovation of this patent. The innovation of this patent lies in facilitating the installation, removal and replacement of the calibration mechanism 1, thereby improving its practicality. Therefore, this patent will not elaborate on its internal structure and working principle.

[0036] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
