Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1, the utility model relates to a locking mechanism, including frame 1, baffle 2, lock frame 3, latch hook 4, reset spring 5 and arch 6, frame 1 is connected with baffle 2, and the left side card of baffle 2 is in frame 1, and the right side of frame 1 is equipped with lock frame 3, is equipped with latch hook 4 and reset spring 5 in the lock frame 3, and latch hook 4 is connected with reset spring 5, and the right side of baffle 2 is equipped with arch 6, and latch hook 4 is connected with arch 6 under lock state.
Frame 1 left side is equipped with and hangs round pin 7, and 2 left sides of baffle are equipped with couple 8, and 8 cards of couple are on hanging round pin 7, and 8 cards of left side of baffle 2 are on frame 1 hangs round pin 7 through couple 8.
The lock frame 3 is also provided with a lock shaft 9, and the lock hook 4 is connected with the lock shaft 9. A return pin 10 is provided at a position of the latch hook 4 connected to the return spring 5. The baffle 2 is a plastic baffle.
Installing a baffle: the left hook 8 of the baffle 2 is clamped on the hanging pin 7 of the frame 1, and the right side of the baffle 2 is pushed to rotate around the hanging pin 7 to move upwards. The lock hook 4 is pushed by the baffle 2 to rotate rightwards, and after the baffle 2 is completely attached to the rack 1, the lock hook 4 resets under the action of the reset spring 5.
As shown in fig. 2, the locked state: the latch hook 4 resets under the action of the reset spring 5 to clamp the baffle 2.
An unlocking process: the latch hook is rotated by directly pushing the reset pin 10 or pushing a slide switch in contact with the reset pin 10, thereby being separated from the blocking plate 2.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
