Description

Technical Field

[0001] The utility model relates to the technical field of mechanical locks, in particular to a simplified mechanical locking device. Background Art

[0002] A mechanical lock is a type of lock that does not rely on electronics or other intelligent technologies. It is usually composed of a key, a lock cylinder, a lock tongue, and other components. The extension and retraction of the lock tongue is controlled by inserting and rotating the key, thereby realizing the functions of unlocking and locking. Mechanical locks have the advantages of simple structure, high reliability, and low cost, and are widely used in homes, offices, warehouses, and other places.

[0003] Nowadays, although various mechanical locking devices can achieve good locking effects, they are often relatively expensive, have short service lives, and some devices are even cumbersome to operate. Using the above complex and expensive mechanical locks in simple places has the disadvantage of low practicality. In order to design a simple mechanical lock suitable for simple places to reduce costs, a simplified mechanical locking device is proposed. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4A simplified mechanical locking device comprises a door frame 1 and a door panel 2. A main shaft 4 is rotatably provided on the door panel 2 through two mounting frames 3. The main shaft 4 is connected to the door frame 1 through a locking mechanism. A through shaft 7 is rotatably provided on the main shaft 4 through a first spring. The through shaft 7 is connected to the door panel 2 through a fixing mechanism. A rotating handle 8 is fixedly provided on the through shaft 7. A connecting frame 11 is installed on the door panel 2. An insertion port 16 is provided on the rotating handle 8. The rotating handle 8 is provided with a dragging port 12. A plug rod extending into the insertion port 16 is slidably penetrated in the dragging port 12 through a second spring. The plug rod is connected to the connecting frame 11 through an insertion mechanism. A dragging ring 13 is provided at the end of the plug rod. The dragging ring 13 is connected to the main shaft 4 through a hanging mechanism.

[0023] The locking mechanism includes a locking shaft 6 mounted on the main shaft 4, and a locking frame 5 is provided on the door frame 1 to cooperate with the locking shaft 6. Figure 2 In the state shown, with the help of the locking shaft 6 and the locking frame 5, the main shaft 4 can no longer rotate, so the door panel 2 can no longer rotate to open.

[0024] The fixing mechanism includes a fixing plate 9 installed on the door panel 2, and a fixing groove 10 corresponding to the through-axis 7 is provided on the fixing plate 9. When the end of the through-axis 7 is in the fixing groove 10, the through-axis 7 cannot rotate relative to the main shaft 4, so the rotating handle 8 cannot be rotated anymore.

[0025] The plug-in mechanism includes an insert block 17 mounted on the connection frame 11 , and a slot corresponding to the insert rod is provided on the insert block 17 . When the insert rod is in the slot, the rotating handle 8 cannot drive the main shaft 4 to rotate.

[0026] The hanging mechanism includes a hanging rod 15 installed on the main shaft 4, and a hanging interface 14 is provided on the rotating handle 8 and the drag ring 13. When the rotating handle 8 is rotated to a vertical state, the hanging rod 15 is in the hanging interface 14 to ensure that the state of the rotating handle 8 is stable.

[0027] The insertion opening 16 and the insertion block 17 are both arc-shaped in vertical section, and the center of the vertical section of the insertion opening 16 and the insertion block 17 is consistent with the center of the through-shaft 7 .

[0028] When the utility model is used, Figure 1 In the state shown, the door panel 2 cannot be rotated to complete the opening operation. When a finger is inserted into the drag ring 13 and then the drag ring 13 is dragged to drive the insertion rod to move and away from the insertion block 17, the insertion rod is disengaged from the slot on the outer wall of the insertion block 17, and the limit of the rotating handle 8 is released. The rotating handle 8 is then rotated to make it vertical, and its hanging rod 15 enters the hanging interface 14. At this time, the rotating handle 8 is stable, and the main shaft 4 is rotated to rotate it toward the direction of the connecting frame 11, so that the locking shaft 6 is disengaged from the locking frame 5, and the limit of the door panel 2 is released, and the door panel 2 can be rotated to open it.

[0029] Before the main shaft 4 rotates to open the door panel 2, the rotating handle 8 is dragged away from the main shaft 4 (the hanging rod 15 is never separated from the hanging interface 14), and the first spring is dragged. When the through shaft 7 rotates to correspond to the fixed groove 10 on the fixed plate 9, the rotating handle 8 is released. At this time, under the action of the first spring, the through shaft 7 enters the fixed groove 10, and the rotating handle 8 can no longer rotate, thereby improving its stability on the main shaft 4.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
