[0002] The locks on diaries usually use a small key unlocking mechanism. This type of lock has a simple design and mainly consists of a lock cylinder, a bolt, a latch, and a key.

[0003] After use, a diary with a lock is locked to prevent others from peeking at its contents. Traditional diary combination locks are knob locks, which work by rotating the knob to a specific combination position and then pressing a button to unlock. After use, the combination is scrambled to make the button unpressable. However, in actual use, there are cases where the combination is forgotten after the knob lock is closed, resulting in the lock being opened directly by pressing the button. Therefore, this solution proposes a secure combination lock for diaries to solve the above problems. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides, for example Figure 1-4 The security combination lock for a diary shown includes:

[0030] Casing 1;

[0031] Guide cylinder 2 is located on the top of housing 1;

[0032] Lock 3 is inserted and connected to the middle of guide cylinder 2;

[0033] Locking component 4 includes a locking tongue 401 that is inserted into the housing 1. The locking tongue 401 is used to fix the position of the latch 3. A driving member is provided on one side of the locking tongue 401, and a pushing member 6 is provided on one side of the locking tongue 401.

[0034] Lifting component 5 is located inside housing 1 and is used to push latch 3.

[0035] It should be noted that the housing 1 and the latch 3 are connected to the front and back of the diary, respectively. When the latch 3 is fixed in place by the locking component 4 inside the housing 1, the diary cannot be opened. The hole in the middle of the guide cylinder 2 matches the latch 3, allowing the latch 3 to pass through the guide cylinder 2 into the housing 1. The guide cylinder 2 restricts the movement of the latch 3, preventing it from moving arbitrarily. When it is necessary to fix the position of the latch 3, the driving component drives the locking tongue 401 to insert into the latch 3. The locking tongue 401 prevents the latch 3 from moving out of the housing 1, thus completing the locking function. To unlock, the locking tongue 401 is moved directly by the drive component, causing it to separate from the latch 3. The latch 3 is then pushed upwards by the lifting component 5. Finally, the locking tongue 401 is reset by the drive component, and the latch 3 is removed from the housing 1 to unlock. After unlocking, the locking tongue 401 is reset by the push component 6. To lock, the latch 3 is inserted into the housing 1 through the guide tube 2, and the locking tongue 401 is pushed towards the push component 6 by pressing the bottom of the latch 3. When the latch 3 moves to the desired position, the locking tongue 401 is inserted into the latch 3 by the push component 6 to lock the latch 3, thus completing the locking function.

[0036] Specifically, the driving components include:

[0037] Drive block 404, which is fixedly connected to one side of the locking tongue 401;

[0038] The push block 407 and the drive block 404 have a through hole 406 in the middle. The push block 407 is inserted into the through hole 406 and has a rotating part at one end.

[0039] It should be noted that the push block 407 is inserted into the inside of the through hole 406. During use, the push block 407 moves to drive the drive block 404.

[0040] Specifically, the horizontal longitudinal section of the through hole 406 is set to square. The inner wall of the bottom end of the housing 1 is fixedly connected with a first support block 402 and a second support block 403 for supporting the driving block 404. The rotating part includes a connecting block 405 fixedly connected to one end of the pushing block 407. A motor 408 is provided inside the housing 1. The connecting block 405 is located at the output end of the motor 408.

[0041] It should be noted that motor 408 is an existing device with a keypad password connected to its control terminal. During use, the user enters the password via the keypad, and the password input module transmits the entered numbers to the control circuit. The control circuit (microcontroller) compares the entered password with the preset password. If the password is correct, the control circuit sends a signal to motor 408, driving motor 408 to rotate. During use, after the user enters the password once, motor 408 drives the connecting block 405 at its output terminal to rotate one revolution. When the connecting block 405 drives the pushing block 407 to move away from the latch 401, the pushing block 407 drives the driving block 404 and the latch 401 to move, thereby removing the latch 401 from the latch 3. The latch 3 moves upward by the lifting component 5, completing the unlocking action. Then, the rotation of the connecting block 405 moves the pushing block 407 closer to the latch 401. At this time, the driving block 4 is pushed by the pushing component 6, causing the latch 401 to reset.

[0042] Specifically, the lifting component 5 includes:

[0043] Lifting block 501 is inserted into the interior of housing 1;

[0044] The first spring 502 is located at the bottom of the lifting block 501.

[0045] It should be noted that the lifting block 501 is located at the bottom of the guide cylinder 2. When the latch 3 is inserted into the housing 1, it first contacts the lifting block 501 and presses the lifting block 501 toward one side of the first spring 502. Then, by moving the latch 401, the latch 401 is inserted into the latch 3, fixing the position of the latch 3. When the latch 401 is moved out of the latch 3, the first spring 502 returns to its original shape and pushes the latch 3 upward.

[0046] Specifically, the pusher 6 includes a second spring 602 located in the middle of the drive block 404, a second support block 403 inserted into the interior of the second spring 602, and a mounting hole 601 provided on one side of the second support block 403, which is inserted into the interior of the second spring 602.

[0047] It should be noted that the top of the second support block 403 is adapted to the mounting hole 601, so that the top of the second support block 403 can be inserted into the interior of the mounting hole 601. When the driving block 404 drives the locking tongue 401 to move towards the side of the motor 408, the second spring 602 is squeezed by the inner wall of the mounting hole 601 and deforms. When the driving block 404 loses the pull and obstruction of the pushing block 407, the second spring 602 will begin to recover its deformation and push the driving block 404 away from the side of the motor 408.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
