Description

Technical Field

[0001] This utility model relates to a lock, and more particularly to a lock with a weighing display function. Background Technology

[0002] When people travel for business or leisure, they typically carry backpacks, suitcases, or duffel bags, and usually lock the zippers with TSA combination locks to prevent unauthorized access. Airports are particularly sensitive to baggage weight when flying, as airlines have strict regulations on carry-on and checked baggage weight. Excessive baggage weight without notice can cause significant inconvenience. Furthermore, in crowded places like airports and tourist attractions, luggage is more likely to be lost or stolen.

[0003] Some TSA combination locks currently have a weighing function, which can determine whether the suitcase is overweight and prepare a contingency plan in advance. However, the information displayed by the TSA combination lock is in a single direction. When the TSA combination lock is inverted, the displayed information is also inverted, which is not convenient for human eyes to see. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a lock with a weighing display function. The lock can automatically adjust the direction of the information displayed on the screen according to the direction of the lock so as to facilitate human observation.

[0005] To achieve the above objectives, the present invention employs the following technical solution: a lock with a weighing display function, comprising a lock housing, a lock cylinder and a lock rope disposed on the lock housing, a display screen disposed on the lock housing, a power supply, a main control circuit board, a weighing sensor and a gyroscope sensor disposed inside the lock housing, the power supply being electrically connected to the main control circuit board, the main control circuit board being electrically connected to the display screen, the weighing sensor and the gyroscope sensor respectively, one end of the lock rope being locked to the lock cylinder, and the other end being connected to the weighing sensor.

[0006] As a further improvement of this utility model, the gyroscope sensor is a nine-axis gyroscope sensor.

[0007] As a further improvement of this utility model, it also includes an operation button, which is disposed on the surface of the lock housing and electrically connected to the main control circuit board.

[0008] As a further improvement of this utility model, the power source is a button battery, the lock shell is provided with a battery compartment, the button battery is placed in the battery compartment, and a battery cover is screwed onto the battery compartment.

[0009] As a further improvement of this utility model, a waterproof sealing ring is provided between the battery compartment and the battery cover.

[0010] As a further improvement of this utility model, the lock cylinder is a rotary combination lock cylinder, and the bottom of the lock cylinder is provided with a keyhole for unlocking.

[0011] As a further improvement of this utility model, the power source is a rechargeable battery, and a charging module is also provided in the lock housing, the charging module being electrically connected to the rechargeable battery.

[0012] The beneficial effects of this utility model are as follows: the lock can measure the weight of luggage in real time, and the weight information is displayed on the screen. At the same time, the lock is equipped with a gyroscope sensor, which senses the direction of the lock and automatically adjusts the direction of the information displayed on the screen according to the direction of the lock, so as to facilitate human observation.

[0018] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0019] like Figure 1-4 As shown, a TSA combination lock with a weighing display function is disclosed. It includes a lock housing 1, a lock cylinder 2 mounted on the lock housing 1, and a locking cord 3. The locking cord 3 is a steel cable used to secure the zipper pull of luggage, preventing it from being opened. The lock cylinder 2 is a rotary combination lock with three sets of numbers. A keyhole 21 for unlocking is located at the bottom of the lock cylinder 2. Unlocking can be achieved by inserting a key into the keyhole 21 or by rotating the lock cylinder 2 using the unlocking combination.

[0020] The surface of the lock housing 1 is provided with a display screen 4 and an operation button 5. Inside the lock housing 1 are a power supply 6, a main control circuit board 7, a load cell 8, and a gyroscope sensor 9. The power supply 6 is electrically connected to the main control circuit board 7, and the main control circuit board 7 is electrically connected to the display screen 4, the load cell 8, the gyroscope sensor 9, and the operation button 5, respectively.

[0021] The power supply 6 is used to power various electronic components. The power supply 6 uses a button battery. A battery compartment 11 is provided on the back of the lock case 1. The power supply 6 is placed in the battery compartment 11. A battery cover 12 is screwed onto the battery compartment 11. A waterproof sealing ring 13 is provided between the battery compartment 11 and the battery cover 12. The battery compartment 11 and the battery cover 12 facilitate the replacement of the power supply 6, and the waterproof sealing ring 13 provides a waterproof function.

[0022] One end of the locking rope 3 is locked to the lock cylinder 2, and the other end is connected to the weighing sensor 8. When using the lock, the locking rope 3 is tied to the luggage, and then the lock and luggage are lifted up. At this time, the weight of the luggage can be measured in real time by the weighing sensor 8 connected to the locking rope 3.

[0023] Display screen 4 displays the weight data measured by the weighing sensor 8. Operation buttons 5 are used to turn the display screen 4 on / off or perform other operations such as tare. The gyroscope sensor 9 is a nine-axis gyroscope sensor used to detect the direction of the lock. When the gyroscope sensor 9 detects that the lock is inverted or horizontally positioned, the main control circuit board 7 automatically rotates the display information on the display screen 4 to a forward-reading direction from left to right, making the information on the display screen 4 easier for the human eye to observe.

[0024] In other embodiments, the power source may be a rechargeable battery, and the lock housing is also provided with a matching charging module, which is electrically connected to the rechargeable battery.

[0025] The above-described embodiments are merely illustrative of this utility model. Any equivalent embodiments made by those skilled in the art without departing from the technical features disclosed in this utility model, and without departing from the technical features of this utility model, shall still fall within the scope of the technical features of this utility model.
