[0005] To achieve the above purpose, the utility model provides the following technical solution: an electronic hanging scale with warning and self-locking functions, including an electronic hanging scale body, the electronic hanging scale body contains a hook, and a warning and self-locking mechanism is arranged on the hook. The warning and self-locking mechanism includes a warning component and a self-locking component. The self-locking component includes a motor, an arc-shaped rack and a driving gear. A motor seat is arranged at the installation end of the hook. The motor is arranged on the motor seat and the output shaft of the motor is connected to the driving gear. The arc-shaped rack is arranged in the hook head end of the hook and can slide in the hook head end of the hook. An opening is formed on the side wall of the hook, and a driven gear is hinged in the opening. The driven gear is respectively meshed with the arc-shaped rack and the driving gear; a protection plate is arranged on one side of the hook, and the warning component is arranged on the protection plate.

[0006] Further, the warning component includes a sensor and an alarm, and the sensor and the alarm are arranged on the protection plate from top to bottom in sequence.

[0007] Further, a storage battery is arranged on the protection plate, and the storage battery is respectively connected to the motor, the sensor and the alarm.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] The utility model has the following beneficial effects:

[0010] The sensor transmits the signal to the PLC controller, which controls the alarm to flash and issue a warning. At the same time, it controls the motor to rotate, driving the connected driving gear to rotate, driving the driven gear to rotate, and then driving the arc-shaped rack to slide inside the hook head of the lifting hook, blocking the opening of the hook head of the lifting hook, thereby realizing the self-locking of the lifting hook to prevent the goods from falling. This device is provided with a warning component and a self-locking component, and can self-lock the lifting hook while giving a warning, thus preventing the goods from moving or falling accidentally.

[0018] Please refer to Figures 1 to 6 , a warning and self-locking electronic hook scale, including an electronic hook scale body 1. The electronic hook scale body 1 is provided with a lifting hook 2. A warning and self-locking mechanism 3 is provided on the lifting hook 2 to give a warning to passing personnel and self-lock the lifting hook 2 to prevent the goods from falling and causing risks. The warning and self-locking mechanism 3 includes a warning component 4 and a self-locking component 5. The self-locking component 5 includes a motor 6, an arc-shaped rack 7, and a driving gear 8. A motor seat 9 is provided at the installation end of the lifting hook 2. The motor 6 is arranged on the motor seat 9 and the output shaft of the motor 6 is connected to the driving gear 8. The arc-shaped rack 7 is arranged inside the hook head end of the lifting hook 2 and can slide inside the hook head end of the lifting hook 2. An opening 10 is formed on the side wall of the lifting hook 2, and a driven gear 11 is hinged in the opening 10. The driven gear 11 is respectively engaged with the arc-shaped rack 7 and the driving gear 8. A protective plate 12 is provided on one side of the lifting hook 2. The warning component 4 includes a sensor 13 and an alarm 14. The sensor 13 and the alarm 14 are arranged on the protective plate 12 from top to bottom in sequence.

[0019] Among them,

[0020] A storage battery 15 is provided on the protective plate 12, and the storage battery 15 is respectively connected to the motor 6, the sensor 13 and the alarm 14.
