Description

Technical Field

[0001] The present invention belongs to the technical field of locks, and particularly relates to a mechanical unlocking linkage mechanism. Background Art

[0002] In modern security and daily use scenarios, locks, as key components for ensuring security and privacy, their performance and operational convenience are crucial.

[0003] Existing mechanical locks, such as common pin tumbler locks, mainly achieve unlocking and locking by inserting a key into the lock core and rotating the lock core to drive the internal pin structure. However, from the perspective of operational convenience, traditional mechanical locks often require precise alignment of the keyhole to perform a relatively complex rotation operation of the lock core. For some people with poor hand flexibility, such as the elderly or those with hand injuries, it is extremely inconvenient to use. Moreover, in a dark environment, it is also difficult to find the keyhole and accurately insert the key, making it inconvenient to use. Summary of the Invention

[0004] The purpose of the present invention is to provide a mechanical unlocking linkage mechanism to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A mechanical unlocking linkage mechanism, comprising:

[0006] A bottom plate, on the surface of which several fixing ears are annularly connected;

[0007] A push plate, which is slidably connected within the bottom plate. A rotating shaft is provided at the center of the push plate, and one end of the rotating shaft is rotatably connected to the bottom plate. The other end of the rotating shaft is connected with a toothed disc, and one end of the toothed disc is fixedly connected with a reset disc, and a linkage rod is detachably connected within the reset disc;

[0008] A gear, which is fixedly sleeved on the rotating shaft. A toothed plate is connected within the push plate, and the gear meshes with the toothed plate. By pushing the push plate to move within the bottom plate and driving the gear to rotate under the action of the toothed plate, the rotating gear drives the linkage rod to rotate through the rotating shaft.

[0009] Preferably, a top cover is connected to one side of the bottom plate, and a cylinder is connected to the middle of the top cover.

[0010] Preferably, a torsion spring is sleeved on the surface of the reset disc, and both ends of the torsion spring are respectively connected with the reset disc and the cylinder.

[0011] Preferably, a push groove is provided within the top cover.

[0012] Preferably, a push block is provided within the push groove, and one end of the push block is connected with the push plate.

[0013] Preferably, a clamping block is connected to the surface of the gear disk, a clamping groove is arranged in the reset disk, and the clamping block is clamped into the clamping groove.

[0014] Preferably, two groups of fixing columns are connected to the surface of the bottom plate.

[0015] Preferably, the linkage rod is semicircularly arranged.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] (1) By pushing the push plate to move in the bottom plate and driving the gear to rotate under the action of the toothed plate, the gear drives the linkage rod to rotate through the rotating shaft, and the linkage rod is inserted into the lock body. The rotation of the linkage rod drives the lock body to rotate, so as to realize the functions of unlocking or locking the lock body. By pushing the push plate, the unlocking-related operations can be completed, greatly reducing the use difficulty and improving the operation convenience.

[0018] (2) When the user no longer applies force to the push block, the torsion spring plays a role. The torsion stored in the torsion spring makes the linkage rod automatically reset, so that the device can automatically return to the initial state after use without manual reset. This not only improves the use convenience, but also ensures the consistency and stability of each operation.

[0019] (3) The linkage rod is detachably connected to the reset disk, so that the linkage rod can be reversely installed according to different door opening directions. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] The present invention provides a mechanical unlocking linkage mechanism as Figures 1-4 shown, including:

[0027] A bottom plate 1, on the surface of which a number of fixing ears 2 are annularly connected;

[0028] A push plate 3, which is slidably connected to the inside of the bottom plate 1. A rotating shaft 5 is provided at the center of the push plate 3, and one end of the rotating shaft 5 is rotatably connected to the bottom plate 1. The other end of the rotating shaft 5 is connected with a gear disk 6, and a reset disk 7 is fixedly connected by clamping at one end of the gear disk 6. A linkage rod 8 is detachably connected inside the reset disk 7. The linkage rod 8 is semicircularly arranged. By the detachable connection between the linkage rod 8 and the reset disk 7, the linkage rod 8 can be reversely installed according to different door opening directions, and the semicircular opening of the linkage rod 8 can be horizontally reversed. In this way, this mechanism can be suitable for installation in different door opening directions.

[0029] A gear 9, which is fixedly sleeved on the rotating shaft 5. A toothed plate 10 is connected inside the push plate 3, and the gear 9 meshes with the toothed plate 10. By pushing the push plate 3 to move inside the bottom plate 1 and driving the gear 9 to rotate under the action of the toothed plate 10, the rotating gear 9 drives the linkage rod 8 to rotate through the rotating shaft 5.

[0030] One side of the bottom plate 1 is connected with an upper cover 11, and a cylinder 12 is connected in the middle of the upper cover 11.

[0031] A torsion spring 13 is sleeved on the surface of the reset disk 7, and both ends of the torsion spring 13 are respectively connected with the reset disk 7 and the cylinder 12.

[0032] A push groove 14 is provided inside the upper cover 11. A push block 15 is provided in the push groove 14, and one end of the push block 15 is connected with the push plate 3. The push groove 14 provides a clear track for the movement of the push block 15, thereby restricting the movement path of the push plate 3. When the push block 15 slides in the push groove 14, it can ensure that the push plate 3 moves smoothly along the predetermined direction, avoiding the deviation or shaking of the push plate 3 during the movement process.

[0033] A clamping block 16 is connected to the surface of the gear disk 6, and a clamping groove 17 is provided inside the reset disk 7. The clamping block 16 is clamped into the clamping groove 17. When assembling the unlocking mechanism, only by aligning the clamping block 16 with the clamping groove 17 and clamping it can the connection between the gear disk 6 and the reset disk 7 be quickly realized, reducing the installation difficulty and improving the assembly efficiency.

[0034] Two groups of fixed columns 4 are connected to the surface of the bottom plate 1. The fixed columns 4 can provide additional fixed support points for the whole mechanism, improving the stability of the mechanism.

[0035] For this mechanical unlocking linkage mechanism, when the user needs to operate the unlocking, directly pull the push block 15 in the push groove 14 to move downward. The push block 15 pulls the push plate 3 to move downward. Since the push plate 3 is slidably connected to the bottom plate 1, under the action of the pulling force, the push plate 3 will move smoothly in a straight line along the track set by the bottom plate 1. With the straight-line movement of the push plate 3, the toothed plate 10 also moves synchronously. Since the gear 9 and the toothed plate 10 are meshed, the straight-line movement of the toothed plate 10 is converted into the circular movement of the gear 9. The rotation of the gear 9 drives the rotating shaft 5 fixed thereto to rotate together. The other end of the rotating shaft 5 is connected to the toothed disc 6. The toothed disc 6 rotates with the rotation of the rotating shaft 5. A reset disc 7 is fixedly clamped at one end of the toothed disc 6, so that the toothed disc 6 can drive the reset disc 7 to rotate synchronously, ensuring the effective transmission of power. A linkage rod 8 is connected in the reset disc 7. When the reset disc 7 rotates with the toothed disc 6, the linkage rod 8 will also rotate (180° to the right) around its own axis. The semicircular shape of the linkage rod 8 enables it to drive the connected lock body to rotate during the rotation process, thus realizing the specific actions of unlocking or locking.

[0036] After the user completes the operation and no longer applies force to the push plate 3, during the previous operation process, the torsion spring 13 undergoes elastic deformation due to the rotation of the reset disc 7 and stores elastic potential energy. When the external force disappears, the torsion spring 13 will release the elastic potential energy, generating a torsion force opposite to the rotation direction of the reset disc 7. Under the action of this torsion force, the reset disc 7 drives the linkage rod 8 to rotate in the reverse direction (180° to the left), returning it to the initial position (as Figure 1 shown), making preparations for the next operation.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
