Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] Please see Figures 1-9 This embodiment provides a fixed combination lock umbrella, the specific idea of ​​which is as follows: In one specific implementation, it includes a main connecting shaft 1, and further includes: Mounting groove 18 is formed on the outer surface of main connecting shaft 1; Hook-shaped iron piece 7 is embedded inside the mounting groove 18; The password component is set on the outer surface of the main connecting shaft 1, including: four digital impellers 2, which allow the hook-shaped iron plate 7 to move by rotating the digital impellers 2; The support assembly is disposed on the outer surface of the main connecting shaft 1, including: an inner sleeve 4, which is sleeved on the outer surface of the main connecting shaft 1 and has a connecting groove 20 inside; One end of the hook-shaped iron piece 7 is embedded in the inside of the connecting groove 20, and a pin 5 passes through one side surface of the hook-shaped iron piece 7 and the outer surface of the inner sleeve 4. The umbrella rod 9 is fixed to the outer surface of the main connecting shaft 1 near the upper end; Connecting pipe 10 is sleeved on the outer surface of umbrella rod 9; The slot 11 is formed on the outer surface of the connecting pipe 10, and one end of the hook-shaped iron piece 7 is embedded in the slot 11.

[0022] In this embodiment, the specific type of the cryptographic component can be various, and this application does not limit it. In an optional scheme, as an example of a cryptographic component, the component includes: a digital pulsator 2, an anti-slip groove 3, and an adjustment groove 16, the specific quantity of each component as follows: Figure 2 and Figure 3 As shown, the settings are as follows: In this embodiment, a digital impeller 2 is provided, which is sleeved on the outer surface of the main connecting shaft 1 and can rotate around the main connecting shaft 1.

[0023] Anti-slip grooves 3, used to increase friction, are milled onto the outer surface of the four digital impellers 2; The adjustment slots 16, which provide adjustment space, are opened inside the four digital impellers 2; In this embodiment, the specific type of the support component can be varied, and this application does not limit it. As an example of an optional support component, the support component includes: an inner sleeve 4, a pin 5, a circular handle sleeve 6, a button 8, a positioning hole 17, a connecting groove 20, a connecting hole 21, and a bolt 22. The specific quantity of each component is as follows: Figure 2 and Figure 3 As shown, the settings are as follows: In this embodiment, an inner sleeve 4 is provided, which is fitted onto the outer surface of the main connecting shaft 1 to provide a support point for the hook-shaped iron piece 7.

[0024] The outer surface of the pin 5 used to connect the hook-shaped iron piece 7 and the inner sleeve 4 is embedded inside the hook-shaped iron piece 7 and the inner sleeve 4, and rotates around the pin 5 as the center when the hook-shaped iron piece 7 is subjected to force. A circular handle sleeve 6 for gripping is fitted onto the outer surface of the main connecting shaft 1 and fixed to the upper surface of the inner sleeve 4, providing a force point for operation; The button 8 for driving the hook-shaped iron piece 7 is embedded in the positioning hole 17 and can move axially along the positioning hole 17. The positioning hole 17 for mounting the button 8 is opened on the outer surface of the circular handle sleeve 6 and is adapted to the shape of the button 8. The connecting slot 20, which provides rotation space, is opened inside the inner sleeve 4; The connecting hole 21 for connecting the button 8 and the hook-shaped iron piece 7 is opened on the side of the button 8 near the hook-shaped iron piece 7. One end of the hook-shaped iron piece 7 is inserted into the connecting hole 21 so that the pressing force of the button 8 can be transmitted to the hook-shaped iron piece 7. Bolt 22, used to fix the circular handle sleeve 6 and the inner retaining sleeve 4, passes through the corresponding holes of the circular handle sleeve 6 and the inner retaining sleeve 4, thereby enhancing the connection stability between the two. In this embodiment, a fixed password is designed at the factory. Each umbrella comes with an instruction manual. Opening the manual reveals the factory's WeChat account and a serial number. Scanning the QR code on the manual with a mobile phone and entering the serial number reveals the umbrella's password. The umbrella's password cannot be changed arbitrarily; there is only one fixed password. Existing combination lock umbrellas consist of an inner ring and an outer number ring. These two parts have been improved and combined into one, requiring only one number wheel for use. In the initial state, one end of the hook-shaped iron piece 7 is embedded in the slot 11 of the connecting tube 10, fixing the connecting tube 10 relative to the umbrella rod 9, and the umbrella is in a locked state. When unlocking is required, rotating the four number wheels 2 increases the friction of the anti-slip grooves 3. To prevent slippage, apply friction until the adjustment slots 16 of the four digital impellers 2 are aligned to form a channel. At this point, press button 8. Button 8 pushes the hook-shaped iron piece 7 to rotate around the pin 5 through the connecting hole 21. The lower end of the hook-shaped iron piece 7 enters the channel formed by the adjustment slot 16, causing the upper end of the hook-shaped iron piece 7 to disengage from the slot 11. The connecting tube 10 can move freely along the outer surface of the umbrella rod 9 to unlock. When locking, push the connecting tube 10 to embed the upper end of the hook-shaped iron piece 7 into the slot 11. Then, rotate the digital impellers 2 in the opposite direction to misalign the adjustment slots 16. The hook-shaped iron piece 7 fits against the inner wall surface of the digital impellers 2, limiting the lower end of the hook-shaped iron piece 7 and locking the connecting tube 10. The structure is simple and reduces production costs. Example

[0025] like Figures 1-9 As shown, based on Embodiment 1, this embodiment also provides a fixed combination lock umbrella. The outer surface of the main connecting shaft 1 is provided with four mounting holes 13 at equal intervals. Springs 14 are embedded in the interior of each of the four mounting holes 13. A ball bearing 15 is provided at one end of each of the four springs 14. Multiple positioning grooves 19 are provided at equal intervals on the inner wall surfaces of the four digital pulsators 2. The outer surfaces of the four balls 15 are embedded in the interior of the corresponding positioning grooves 19. Both the outer surface of the circular handle sleeve 6 and the outer surface of the main connecting shaft 1 are provided with password positioning lines 12.

[0026] In this embodiment, when the digital pulsator 2 is rotated, the ball bearing 15, under the elastic force of the spring 14, will sequentially engage with different positioning slots 19 as the digital pulsator 2 rotates. Each engagement with a positioning slot 19 generates a clear feedback point, intuitively indicating to the user that a number scale rotation has been completed, facilitating precise adjustment of the number position. When the target numbers on the four digital pulsators 2 are aligned with the password positioning lines 12 on the outer surface of the circular handle sleeve 6 and the main connecting shaft 1, the adjustment slots 16 on the inner wall of the digital pulsator 2 are precisely aligned to form a continuous channel. At this time, the hook-shaped iron piece 7 can move smoothly to achieve the unlocking operation, improving the user experience.

[0027] Working principle: In the initial locked state, the upper end of the hook-shaped iron piece 7 is embedded in the slot 11 of the connecting tube 10, and the lower end is embedded in the connecting groove 20 of the inner sleeve 4. It is hinged and limited by the pin 5, so that the connecting tube 10 cannot move along the umbrella rod 9. When unlocking, you need to hold the round handle sleeve 6 and rotate the four digital pulsators 2 with the help of the anti-slip groove 3 on the outer surface of the digital pulsator 2 until the inner wall adjustment groove 16 is aligned to form a channel. Then press the button 8. The button 8 pushes the hook-shaped iron piece 7 to rotate around the pin 5 through the connecting hole 21, so that the upper end of the hook-shaped iron piece 7 is disengaged from the slot 11. When locking, you only need to push the connecting tube 10 to make the slot 11 push the upper end of the hook-shaped iron piece 7 back into the slot 11. Then rotate the digital pulsator 2 in the opposite direction to make the adjustment groove 16 misaligned. The lower end of the hook-shaped iron piece 7 is fixed by the inner wall of the digital pulsator 2.

[0028] When unlocking, rotating the digital pulsator 2 causes the ball bearing 15 to rotate with the digital pulsator 2 under the action of the spring 14 and engage in different positioning slots 19, generating feedback prompts for digital scale adjustment. The target number on the digital pulsator 2 must be aligned with the password positioning line 12 to ensure that the adjustment slot 16 is accurate and continuous. When locking, rotating the digital pulsator 2 in the opposite direction allows the ball bearing 15 to engage in new positioning slots 19 to fix the position of the digital pulsator 2, preventing unauthorized rotation and greatly improving operational accuracy and stability.
