Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

A trailer station as shown in figures 1-7 consists of a mechanical lock mechanism 10, a fingerprint lock mechanism 22 and a lock housing 14. The top of the lock shell 14 is provided with a lock slot 101, and the trailer rod 40 is arranged in the lock slot 101. The middle part of the trailer rod 40 is a main rod 41, the lower part is an insertion rod 42, and the diameter of the insertion rod 42 is smaller than that of the main rod 41. The diameter of the locking groove 101 is equal to that of the insertion rod 42, a circle of groove 43 used for being matched with the trailer lock is arranged on the insertion rod 42, and the diameter of the groove 43 is smaller than that of the insertion rod 42.

Furthermore, a lock channel 102 is arranged on one side of the lock case 14, a cavity 20 for accommodating the fingerprint lock mechanism 22 is arranged on the other side of the lock case, the lock channel 102 is communicated with the cavity 20, and the lock channel 102 is partially communicated with the lock channel 102 and approximately occupies one half. The mechanical lock mechanism 10 comprises a lock cylinder 103, a lock tongue 104, a torsion spring buckle 106 and a torsion spring 105, and a fixing plate 21 is installed and connected in the cavity 20 through a bolt. The torsion spring buckle 106 is disposed on one side of the fixing plate 21 close to the bolt 104, the torsion spring buckle 106 is disposed in the lock passage 102, the bolt 104 is connected to the torsion spring buckle 106 through a torsion spring 105, a convex pillar for clamping the torsion spring 105 is disposed on the torsion spring buckle 106, and the torsion spring 105 is clamped to the torsion spring buckle 106 through the convex pillar. The locking tongue 104 is provided with a clamping groove 104a for matching with the groove 43 to be clamped, and when the bottom of the clamping groove 104a is abutted against the top of the groove 43, the locking state is achieved; when the groove 43 is rotated clockwise by a certain angle, the notch of the locking groove 104a is parallel to the notch at the intersection of the lock channel 102 and the locking groove 101, and is in an unlocking state.

Further, a latch slot 109 is formed on a side portion of the lock housing 14 close to the lock cylinder 103, a rotation slot 103a is formed on a side portion of the lock cylinder 103, the lock cylinder 103 is connected with a pin shaft 109a through the latch slot 109, and one end of the pin shaft 109a is inserted into the rotation slot 103 a. The pin 109a is in a locked state when it abuts the bottom of the rotary groove 103a, and in an unlocked state when the pin 109a abuts the top of the rotary groove 103 a.
