[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0025] like Figures 1 to 5 As shown, this embodiment provides a blade mechanical lock cylinder, including a lock shell 1, a lock cylinder 2, a blade assembly 3, and a mortise lock 4. The lock shell 1 has a first through hole 101, and the lock cylinder 2 is installed within the first through hole 101. The lock cylinder 2 has several blade through holes 201, and the blade assembly 3 is respectively disposed within each blade through hole 201. The lock shell 1 has a first slot 102, and the mortise lock 4 is disposed within the first slot 102 and will fit inside the lock cylinder 2. A [missing information - likely a design feature] is provided at the bottom of the first slot 102. The second slot 103 is horizontal, and the pawl 4 is fixed in the middle of the lock cylinder 2. The pawl 4 is located in the first slot 102. The end of the pawl 4 extends horizontally to form a hook 41. The pawl 4 and the hook 41 are generally set at a right angle. The hook 41 is located in the second slot 103. When the key is inserted into the lock cylinder 2, the blade assembly 3 cooperates to open the lock cylinder 2. The lock cylinder 2 rotates, which drives the pawl 4 to rotate. This structure can shorten the length of the lock cylinder and maintain the width of the pawl's movement, retain the password length of the existing key, and is easy to install and has low cost.

[0026] As an optional embodiment, the blade assembly 3 includes a first blade 31 and a second blade 32. A first spring 33 is disposed between the first blade 31 and the second blade 32. A third slot 301 is disposed at the bottom of the first blade 31 and the second blade 32. A fourth slot 104 is disposed inside the lock housing 1. A limiting block 34 is disposed between the third slot 301 and the fourth slot 104. A second spring 35 is disposed at the bottom of the limiting block 34. A support plate 36 is disposed at the bottom of the second spring 35. When the lock cylinder is not inserted with a key, the first spring supports and separates the first blade 31 and the second blade 32. When the third slot 301 is not on the same straight line, it will push the limiting block 34 down to jam the lock cylinder and prevent it from rotating. When the key is inserted, the first spring is compressed and the first blade 31 and the second blade 32 are tightened. The third slot 301 overlaps and causes the limiting block 34 to rise, thereby preventing the lock cylinder from rotating.

[0027] As an optional embodiment, the fourth slot 104 in the lock housing 1 extends to the pawl 4, thereby extending the length of the limiting block 34.

[0028] As an optional embodiment, the lock cylinder 2 is provided with an annular groove 202, and a retaining ring 21 is installed on the annular groove 202. The retaining ring 21 is located in the first slot 102. The lock cylinder 2 can be fixed in the lock shell 1 for rotation, but cannot move back and forth.

[0029] As an optional embodiment, a notch 203 is provided at the position of the locking core 2 fitted on the pebbles 4. The notch 203 is located corresponding to the pebbles 4 and drives the pebbles 4 to rotate when the locking core 2 rotates.

[0030] As an optional embodiment, the lock cylinder 2 is provided with a through keyhole 204, and the first blade 31 and the second blade 32 are correspondingly matched with the keyhole 204.

[0031] As an optional embodiment, the first slot 102 divides the first through hole 101 into a front through hole and a rear through hole, and the blade assembly 3 is respectively disposed in the front through hole and the rear through hole. This can extend the length of the password area, which is similar to the length of the key in the prior art. Even when the lock cylinder is shortened, the key can still maintain the state of the prior art.

[0032] As an optional embodiment, two second springs 35 are provided, and they are respectively located in the front through hole and the rear through hole. This can achieve the balance of the limiting block and avoid uneven height.

[0033] As an optional embodiment, the second slot 103 is located in the middle of the lock case 1.

[0034] The lock cylinder 2 is installed in the first through hole 101 of the lock shell 1. The first slot 102 divides the first through hole 101 into a front through hole and a rear through hole. The retaining ring 21 is fastened to the lock cylinder 2 in the first slot 102. The blade assembly 3 is respectively set in the front through hole and the rear through hole. There are two second springs 35, which are respectively located in the front through hole and the rear through hole. Rotating the lock cylinder 2 drives the tumbler 4 to rotate, which allows the key to reach its longest length to meet a variety of passwords, and the lock cylinder length can be minimized. This lock cylinder length can be directly installed on the lock body at the factory, and then directly installed inside the door after shipment, without the need for separate installation, thus improving work efficiency.

[0035] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited thereto. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model are equivalent substitutions and are included within the protection scope of the present utility model.
