AI Technical Summary
Existing polymer material covers are prone to aging in outdoor environments, affecting disassembly. How can we provide a more durable keyhole structure and cover connection method that also features a durable and easy-to-store lock?
The metal cover is threaded to the limiting part, and a permanent magnet is set inside the cover. The magnetic adsorption function of the permanent magnet is used to store the cover. Combined with the O-ring sealing design, the durability and stability of the connection are enhanced.
It achieves a reliable connection between the cover and the limiting part, improves the durability and stability of the pin lock, and facilitates the storage of the cover through the adsorption function of the permanent magnet, avoiding the aging problem of polymer materials.

Abstract
Claims
1. A pin lock characterized by, include: Shaft body; Limiting portions are provided at both ends of the shaft, wherein the first limiting portion and one end of the shaft are detachably connected by a locking mechanism. The locking mechanism includes a lock cylinder and a lock rod. The lock cylinder is disposed on the first limiting part, and the lock rod is formed from the end of the shaft near the first limiting part. The lock cylinder and the lock rod cooperate to realize the locking and unlocking of the locking mechanism. The lock cylinder also includes a lock hole, which is disposed at the end of the first limiting part away from the shaft. A removable cover is provided outside the lock hole. The cover is made of metal. The cover and the first limiting part are connected by threads. When the cover and the first limiting part are connected, the lock hole is accommodated between the cover and the first limiting part. A permanent magnet is fixed on the cover.
2. The pin lock of claim 1, wherein The cover is cup-shaped. When the cover is connected to the first limiting part, at least a portion of the cover is fitted outside the first limiting part, and the permanent magnet is disposed inside the cover.
3. The pin lock of claim 2, wherein, The cover and the first limiting part are configured such that when the thread engagement of the cover and the first limiting part reaches the maximum engagement length, there is a gap between the permanent magnet and the lock cylinder.
4. The pin lock of claim 3, wherein The permanent magnet is ring-shaped.
5. The pin lock of claim 3, wherein The permanent magnet is pressed into the inner wall of the cover by screws.
6. The pin lock defined in claim 2, wherein An O-ring is provided on the outer side of the first limiting part or the inner side of the cover. The position of the O-ring is set such that when the thread engagement between the cover and the first limiting part reaches the maximum engagement length, the first limiting part and the cover are sealed together by the O-ring.
7. The pin lock of claim 1, wherein The pin lock also includes a magnetic component made of magnetic material, which can be magnetized by the permanent magnet so that the magnetic component is magnetically attracted to the permanent magnet.
8. The pin lock of claim 7, wherein, The shaft is the magnetic component.
9. The pin lock of claim 7, wherein, The pin lock further includes a second limiting part, which is disposed at one end of the shaft away from the first limiting part, and the magnetic element is disposed at the end of the second limiting part away from the first limiting part.
10. The pin lock of claim 1, wherein The shaft is also provided with at least one through hole, and the elastic pin is detachably disposed in the through hole.
