[0002] With the rapid development of science and technology and the improvement of global transportation networks, people's desire and ability to cross geographical boundaries and explore the world are becoming stronger. In this context, suitcases have become a powerful assistant for travel and mobile office. However, as the value and diversity of items loaded in suitcases continue to increase, the safety requirements for suitcases have also risen accordingly. The traditional zipper closure method, although simple and fast in operation, has hidden dangers that cannot be ignored in terms of safety. The original design of the zipper is for quick opening and closing, which happens to be its weak point in safety. Once it is maliciously damaged, such as with sharp tools, it can be easily opened and closed. The fabric around the zipper can be easily scratched, and the zipper can be restored with simple operations, thus quietly opening the suitcase, resulting in the loss of valuables inside the suitcase, causing significant economic losses and mental distress to passengers. In order to solve this problem, suitcases equipped with higher-level security locks have gradually emerged on the market. Among them, combination locks are a more common choice. Although they have improved the protection level to a certain extent, traditional mechanical combination locks often have problems such as limited combination combinations and easy cracking, and lack of instant alarm function. Once the password is cracked or forgotten, it is often difficult for users to discover and take measures in time. Utility Model Content

[0023] like Figures 1 to 7 As shown, the utility model provides a hard trolley case with an anti-theft lock, comprising a case body 1, with a connecting piece 1 2 and a connecting piece 2 3 fixedly mounted on the sides of the case body 1 in sequence, a bolt 4 movably mounted between the connecting piece 1 2 and the connecting piece 2 3, a fixing block 5 provided below the connecting piece 2 3 and fixedly mounted on the surface of the case body 1, a round rod 6 movably mounted inside the fixing block 5 and passing through the bolt 4, a handle 7 fixedly mounted on one end surface of the round rod 6, a spring 1 8 provided between the handle 7 and the fixing block 5, a fingerprint device 9 fixedly mounted on the front of the fixing block 5, and an alarm device 10 fixedly mounted on the right side of the fixing block 5;

[0024] Adopting the above solution: This device means that only the legal owner of the box or an authorized person can open the box, which greatly reduces the risk of illegal opening by others, making it safer than traditional combination locks or key locks. At the same time, this device is faster and more convenient to use, thereby improving the user experience, and this device can significantly enhance the user's sense of psychological security, allowing them to travel more confidently and enhance their psychological security.

[0025] like Figure 3 As shown, a sleeve 11 is fixedly installed in the recessed area at the top of the box body 1, a circular hole 14 is formed on the surface of the sleeve 11, an inner rod 12 is movably installed inside the sleeve 11, a circular groove 15 is formed on the surface of the inner rod 12, a button 16 is movably installed inside the circular hole 14, a spring 17 is provided between the inner wall of the circular groove 15 and the button 16, a pull rod 13 is fixedly installed on the top of the inner rod 12; an anti-slip layer 18 is fixedly installed on the surface of the pull rod 13, and the anti-slip layer 18 is made of leather;

[0026] The above solution is adopted: through this device, the inner rod 12 can be locked at multiple preset height positions to meet the needs of users of different heights or adapt to the height requirements in different scenarios, thereby improving the practicality of the device. At the same time, this device only requires the user to quickly adjust the height of the inner rod with a light press. After the adjustment is completed, it can be automatically locked in the current position by lightly pressing again. This not only simplifies the operation process, but also improves the convenience and efficiency of the operation. By fixing an anti-slip layer 18 on the surface of the pull rod 13, and the anti-slip layer 18 is made of leather, the user's comfort when pushing the box 1 is improved.

[0027] like Figure 2 As shown, two sets of universal wheels 20 are movably installed at the bottom of the box body 1 and two sets of support bases 21 are fixedly installed. The two sets of universal wheels 20 correspond to the two sets of support bases 21 one by one.

[0028] The above solution is adopted: by movably installing two sets of universal wheels 20 and fixedly installing two sets of support seats 21 at the bottom of the box body 1, and the two sets of universal wheels 20 correspond to the two sets of support seats 21 one by one, thereby improving the overall stability of the box body 1.

[0029] like Figure 3 As shown, the inner diameter of the circular groove 15 is equal to the outer diameter of the button 16, and the number of circular holes 14 on the surface of each set of sleeves 11 is nine;

[0030] The above solution is adopted: by setting the inner diameter value of the circular groove 15 and the outer diameter value of the button 16 to be equal in size, the button 16 can fit more closely when moving inside the circular groove 15, and the number of circular holes 14 on the surface of each group of sleeves 11 is nine, thereby improving the flexibility of the device.

[0031] like Figure 1 and Figure 5 As shown, reinforcing ribs 19 are fixedly installed on both sides of the fixing block 5. The shape of the reinforcing ribs 19 is triangular. The box body 1 is made of aluminum-magnesium alloy as a whole, and the corners of the box body 1 are all set to be rounded.

By making the entire box body 1 of aluminum-magnesium alloy, the load-bearing capacity and stability of the trolley case are improved, and the corners of the box body 1 are set to be rounded to reduce the degree of injury.

[0033] The working principle and use process of this utility model:

[0034] During use, the user first combines the connecting piece 1 2 and the connecting piece 2 3 through the bolt 4, and then the worker pulls the handle 7 to make the spring 1 8 in a stretched state, and then aligns the round rod 6 with the notch of the bolt 4. After releasing the hand, the reaction force of the spring 1 8 clamps the round rod 6 inside the bolt 4 to complete the final assembly. However, when it is necessary to disassemble, just touch the fingerprint device 9 with your finger. The fingerprint device 9 will scan the fingerprint of the finger before pulling the handle 7. If the fingerprint does not match, the fingerprint device 9 will transmit a signal to the alarm device 10, and then the alarm device 10 will sound an alarm.

[0035] When the height of the inner rod 12 needs to be adjusted, the user only needs to press the button 16 so that the button 16 enters the inside of the circular groove 15 and at the same time squeezes the spring 2 17 so that it is in a compressed state. Then the user pulls the inner rod 12 so that the inner rod 12 slides inside the sleeve 11 and slides to a suitable position. The reaction force of the spring 2 17 pushes the button 16 out of the circular groove 15 and resets it, thereby limiting the sleeve 11 and the inner rod 12.
