[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0026] Reference Figure 1-6As shown, this is a preferred embodiment of the ladder quick-storage structure, including a ladder sleeve 1, a gear box body 4, and a connecting rod 5. The gear box body 4 is installed on one of the ladder sleeves 1, and the connecting rod 5 passes through the gear box body 4 to connect two ladder sleeves 1. By operating the locking key 2 on one side, the mechanism inside the gear box body 4 is driven to realize the ladder storage. Further, it includes a locking key 2 and a metal shell 3. There are two locking keys 2, located on the left and right sides of the outer end of the metal shell 3. The metal shell 3 encloses the shell of the internal parts, and the ladder sleeve 1 protrudes from both ends of the metal shell 3. The metal shell 3 is set to protect and support the internal components, improving the protective performance of the device. Further, the gear box body 4 includes a gear box cover 7, a plastic movable part 8, a gear body 9, a circular gasket 13, and a metal shaft 14. The gear box cover 7 covers the top of the gear box body 4. The plastic movable part 8 is "L" shaped and located on both sides inside the gear box body 4, clamping the gear body 9 in the middle. The gear body 9 is located in the middle of the gear box body 4. The circular gasket 13 serves as a connection between the gear box body 4 and the gear box body 4. The metal shaft 14 passes through the circular washer 13 and the gear body 9, fixing them in the middle of the gear box body 4. The circular washer 13 acts as a buffer and protector, reducing mechanical damage to the internal components of the device during daily use and extending the service life of the device. The left plastic movable part 8 is L-shaped and is clamped on the left side of the gear body 9. When it moves into the gear box body 4, it pushes the gear body 9 around the metal shaft 14. The circular washer 13 above and below the gear body 9 reduces rotational friction and ensures smooth transmission. The gear box cover 7 fixes the position of the gear body 9 and prevents axial movement. When the gear body 9 rotates, the right plastic movable part 8 is engaged and driven by the gear body 9, moving in the opposite direction. Further, a square washer 12 is included. The square washer 12 can be embedded in the outer plastic movable part 8. The square washer 12 has a thread in the middle, which can fix the connecting rod 5 in one of the plastic movable parts 8. The right plastic movable part 8 is fixedly connected to the connecting rod 5 through the square washer 12. When the plastic movable part 8 moves outward, it pulls the connecting rod 5 to move to the right.

[0027] Reference Figure 1-6 As shown, the plastic movable part 8 is connected to a metal locking shaft 6 by a screw. The screw passes through the wall thickness of the plastic movable part 8 and one side of the gear box body 4. One side of the gear box body 4 can be fixed on the ladder sleeve 1. When the left locking key 2 is pressed with one hand, the mechanical structure of the locking key 2 pushes the metal locking shaft 6 connected to it to move into the gear box body 4. The metal locking shaft 6 is fixedly connected to the left plastic movable part 8 by a screw. Therefore, pressing the locking key 2 directly drives the plastic movable part 8 to move synchronously. Furthermore, there are two ladder sleeves 1. The two ladder sleeves 1 are located at both ends of the product. The ladder sleeves 1 are circular and can be inserted into the ladder components.

[0028] Reference Figure 1-6As shown, the device includes a plastic connector 11 and a spring 10. The plastic connector 11 is fixed to the ladder sleeve 1, which is not connected to the gear box body 4. The spring 10 is placed inside the plastic connector 11, and another spring 10 is placed on one side of the gear box body 4. Its structure is adapted to the plastic connector 11. The spring 10 on the left ladder sleeve 1 and the spring 10 on one side of the gear box body 4 release their elastic force at the same time. The spring 10 pushes the left locking key 2 and the metal locking shaft 6 to reset. The gear body 9 rotates counterclockwise, driving the right plastic movable part 8 and the connecting rod 5 to reset. The metal locking shaft 6 is reinserted into the right ladder sleeve 1, completing the locking.

[0029] Reference Figure 2-6 As shown, the device includes a connecting rod 5 and a metal locking shaft 6. The metal locking shaft 6 is placed in the ladder sleeve 1. The connecting rod 5 has threads at both ends and is fixed to one of the metal locking shafts 6 by the threads. The metal locking shaft 6 is placed in the ladder sleeve 1 that is not connected to the gear box body 4. The other end of the connecting rod 5 is fixed to one end of one of the plastic movable parts 8. The connecting rod 5 connects the two ladder sleeves 1 together. By setting the connecting rod 5 to connect the two ladder sleeves 1 together, the device can store the ladder by pressing the locking part on either side with one hand, which is convenient and quick to store and improves the convenience of the device. The other end of the connecting rod 5 is fixed to the metal locking shaft 6 in the right ladder sleeve 1 by the threads. Therefore, pulling the connecting rod 5 will cause the metal locking shaft 6 to be pulled out of the ladder sleeve 1 and released from the lock.

[0030] Specific implementation process: When the left lock key 2 is pressed with one hand, the mechanical structure of the lock key 2 pushes the metal lock shaft 6 connected to it to move into the gear box body 4. The metal lock shaft 6 is fixedly connected to the left plastic movable part 8 by screws. Therefore, pressing the lock key 2 directly drives the plastic movable part 8 to move synchronously. When it moves into the gear box body 4, it pushes the gear body 9 to rotate around the metal shaft 14. The circular pads 13 on the upper and lower parts of the gear body 9 reduce rotational friction and ensure smooth transmission. The gear box cover 7 fixes the position of the gear body 9 to prevent axial movement. When the gear body 9 rotates, the plastic movable part 8 on the right is engaged and driven by the gear body 9 to move in the opposite direction. The other end of the connecting rod 5 is fixed to the metal lock shaft 6 in the right ladder sleeve 1 by threads. Therefore, pulling the connecting rod 5 will drive the metal lock shaft 6 to be pulled out from the ladder sleeve 1, releasing the right lock. When the left metal lock shaft 6 moves inward with the lock key 2 being pressed, it is directly pulled out from the left ladder sleeve 1, releasing the left lock. At this time, the locking state of the left and right ladder sleeves 1 is released at the same time, and the ladder can be folded and stored.

[0031] The ladder transforms the operation of one-handed locking key 2 on one side into the synchronous unlocking action of both ladder sleeves 1 through the mechanical transmission mechanism inside the gear box body 4, realizing the "one-handed quick retraction" function. The key lies in the use of the meshing transmission of the gear body 9 and the rigid connection of the connecting rod 5 to break the limitation of traditional two-handed operation.
