[0052] The sidewalls on both sides of the missing groove 461 are provided with notches 462, and the end of the hook 45 away from the hook tip is fixedly connected with a short pin 463, and the hook 45 is rotatably connected in the notches 462 through the short pin 463.

[0053] The hook 45 can be turned downward into the missing groove 461 through the short pin 463.

[0054] The short pin 463 is sleeved with a torsion spring 464, and the two ends of the torsion spring 464 are connected to the short pin 463 and the notch 462 respectively. When the key ring touches the horizontally placed hook 45, the hook 45 is pressed and the torsion spring 464 is compressed to deflect downward, until the hook 45 is embedded in the notch 462. At this time, the key ring and the corresponding hook 45 are downwardly attached to the wall of the arc pipe 44, so as to leave the central space in the pipe to avoid obstruction, so that the subsequent key ring can continue to be hung on the next hook 45, and the alternately effective several hooks 45 in a single arc pipe 44 are realized.

[0055] The lower side of the inner wall of the cabinet body 1 is fixedly connected with a partition plate 465, and the partition plate 465 separates the bottom area of the cabinet body 1 into a bottom drawer 466. The bottom of the arc pipe 44 is fixed on the partition plate 465, and the partition plate 465 is provided with a through opening 467 corresponding to the arc pipe 44.

A tension spring (4682) is provided between the bottom of the plate base (4681) and the bottom surface of the partition (465), and the tension spring (4682) pulls the plate base (4681) upward. A steel sheet (4683) is fixedly installed on the top of the plate base (4681). A slot (4684) communicating with the inside of the arc tube (44) is opened on the side surface of the top. When the plate base (4681) moves upward, it pushes the steel sheet (4683) to bend and insert into the slot (4684) to close the arc tube (44). A locking pin (4685) is fixedly connected to the hook (45), and the locking pin (4685) and the hook (45) are arranged opposite to each other along the short pin (463). The surface of the plate base (4681) is provided with a slot (4686) corresponding to the locking pin (4685), and the locking pin (4685) is horizontally locked in the slot (4686) to restrict the plate base (4681) from sliding upward. The end of the locking pin (4685) is provided with a locking tooth (4687), and when the locking pin (4685) rotates upward, the plate seat (4681) slides upward and is limited by the locking tooth (4687) at the rear. When the locking pin (4685) rotates downward, the locking tooth (4687) presses against the plate seat (4681) to slide downward.

4. A key cabinet for convenient key storage and management according to claim 3, characterized in that: The magnetic strips for the traction key are fixedly embedded on the left and right sides of the inner wall of the arc tube (44) and near the hook (45).

5. A key cabinet for convenient key storage and management according to claim 4, characterized in that: The lower side of the cabinet door (2) is cut into an open bottom drawer (466).

6. A key cabinet for convenient key storage and management according to claim 5, characterized in that: A cotton pad is provided on the bottom wall of the bottom drawer (466).

7. A method for using a key cabinet for convenient key storage and management according to claim 6, comprising the following steps: S1. Insert multiple key strings into the groove (41) at the top of the cabinet (1). The keys enter the groove (41) from the left side. The operator pushes the key strings from the left side of the groove (41) to the right side. During this process, the key strings with different numbers of keys fall into the different diameter slots (43) according to their size. The key strings enter the arc tube (44) along the slots (43) and fall onto the hook (45) for hanging. S2. During the process of the key chain falling into the arc tube (44), the key chain touches the horizontal hook (45) and is hooked along the hook (45), so that the hook (45) is under the weight and the short pin (463) compresses the torsion spring (464) to deflect downward until the hook (45) is embedded in the notch (462). At this time, the key chain and the corresponding hook (45) turn down and fit against the wall of the arc tube (44), thereby making room in the center of the tube to avoid obstruction, so that subsequent key chains can continue to be hooked on the next hook (45). The user can push several key chains into the arc tube (44) at the same time for automatic sequential hooking. S3. After the hook (45) is deflected downward into the notch (462) under the weight, the hook head (452) of the hook (45) carries the key chain. Under the weight, the pin (4610) moves downward. The pin (4610) uses friction to drive the rubber wheel (4612) and the magnetic hook (4613) to deflect upward, so that the magnetic hook (4613) is attracted to the hook head (452) to close the hook ring. At this time, the key chain is locked in the hook ring and cannot be removed. S4. When the hook (45) is hooked onto the key and deflects downward under load, the opposite locking pin (4685) deflects upward simultaneously and releases the lock on the plate base (4681) along the slot (4686). When all the hooks (45) in the arc tube (44) are hooked onto the key chain, all the locking pins (4685) release the lock on the plate base (4681). The tension spring (4682) at the bottom of the plate base (4681) pulls it upward and moves the top steel plate (4683) along the slot (4686). 684) is pushed in, so that the steel plate (4683) closes the current arc tube (44), thereby indicating that the arc tube (44) has no storage capacity. When one of the key strings is removed, the torsion spring (464) pushes the hook (45) to rotate upward and the locking pin (4685) to rotate downward. The locking pin (4685) uses the locking teeth (4687) that engage with the upper plate seat (4681) to press down the plate seat (4681) and pull the steel plate (4683) out of the arc tube (44) to open the arc tube (44).
