Description

Technical Field

[0001] This utility model relates to the field of mechanical combination lock technology, specifically a novel mechanical lock. Background Technology

[0002] A combination lock is a type of lock that is opened by entering a preset combination of numbers, letters, or symbols. Compared to traditional mechanical locks, it does not require carrying a key, making it more convenient and gradually becoming one of the options for improving security.

[0003] Mechanical combination locks rely on mechanical structures to recognize and unlock the lock. They typically use a rotary or push-button design and have a simple structure. When changing the combination, traditional combination locks simply require opening the lock and turning the set combination. This has low security performance and cannot effectively provide security protection, making it easy for the combination to be changed arbitrarily. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel mechanical lock that solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A novel mechanical lock includes a lock cover and a lock base. The lock cover has an insertion hole on its side. The lock cover and the lock base are fixedly connected by screws. A first fixing block and two symmetrically distributed fixing blocks are fixed on the lock base. A support rod is rotatably connected to the second fixing block. An adjusting lock mechanism is provided on the support rod. A push block is slidably provided on the lock base. The upper end face of the push block is grooved. A first spring is fixed between the top of the push block and the first fixing block. A rotating groove is provided at the lower end of the lock base. A rotating mechanism is rotatably provided in the rotating groove. An unlocking plate is provided below the lock base. The unlocking plate is matched and correspondingly provided with the rotating mechanism. The unlocking plate drives the rotating mechanism to rotate, causing the adjusting lock mechanism to move closer to the rotating mechanism. The lock head in the groove of the push block separates from the adjusting lock mechanism.

[0006] Furthermore: the adjusting lock mechanism includes a latch, which is slidably positioned back and forth on the lock seat. Lock plates are fixed on both sides of the latch, and a lock insert is fixed on the inner end of the lock plate. A placement groove is provided on the upper end of the latch, and a second spring is provided in the placement groove. A baffle is fixed at the top inside the lock cover, and the baffle is inserted into the placement groove and positioned inside the second spring. The lock head is inserted from the insertion hole into the groove above the push block and presses the latch. The latch moves backward under the action of the second spring, and the latch is pushed out and locked with the lock head by the rebound force of the second spring.

[0007] Furthermore, the adjusting lock mechanism also includes a pushing center plate, the lower end of which is fixed with a stop plate. The rotation of the rotating mechanism squeezes the stop plate, causing the pushing center plate to move left and right. A fixed wheel is fixed on the support rod, one end of which is positioned to abut against one end of the pushing center plate. When the pushing center plate moves, it causes the fixed wheel to move as a whole.

[0008] Furthermore: a combination wheel is rotatably mounted on the support rod, teeth are fixed inside the inner ring of the combination wheel, and a clearance groove is provided inside the inner ring of the combination wheel. The teeth and the clearance groove each occupy half of the interior of the combination wheel. A locking block is fixed to the side of the fixed wheel, and the locking block is matched and engaged with the teeth. A locking groove is provided on the side of the fixed wheel, and the locking groove is matched and engaged with the locking plug.

[0009] Furthermore: when the fixed wheel and the push center plate move to one side, the locking block disengages from the teeth, the password wheel rotates arbitrarily to adjust the password numbers, after adjustment the push center plate and the fixed wheel return to their original positions, the locking block engages with the teeth, locks the corresponding numbers, and confirms the password.

[0010] Furthermore: the rotating mechanism includes a rotating plate, which is rotatably arranged in a rotating groove. A tube is fixed at the lower end of the rotating plate, and the tube is correspondingly arranged with the unlocking piece. A stop block is fixed at the upper end of the rotating plate. The stop block interacts with the stop plate as the rotating plate rotates, thereby driving the central plate to move. A third spring is fixed on the outside of the fixed wheel. When the teeth correspond to the locking block, the third spring pushes the whole back to its original position.

[0011] This utility model provides a novel mechanical lock. Compared with the prior art, it has the following advantages:

[0012] This new type of mechanical lock allows for combination adjustment via the rotation of the unlocking plate and the rotating of the combination wheel after unlocking. The combination wheel can be rotated as needed. Its mechanical mechanism is stable, easy to operate, and not easily damaged. It is also fixed when the lock head is inserted, further improving ease of use. With the unlocking plate, it is safer and more stable. Attached Figure Description

An unlocking plate 28 is provided below the lock base 4, corresponding to the rotating mechanism. When the combination of the adjusting lock mechanism is correctly rotated, the plate moves closer to the rotating mechanism, causing the lock head in the groove of the push block 8 to separate from the adjusting lock mechanism, thus unlocking the lock. The adjusting lock mechanism is a combination lock, allowing users to customize the combination, improving security.

[0022] The adjusting lock mechanism includes a latch 9, which is slidably positioned on the lock seat 4 with front and rear limits. Lock plates 13 are fixed on both sides of the latch 9, and a lock insert 14 is fixed on the inner end of the lock plate 13. A placement groove 10 is provided at the upper end of the latch 9, and a second spring 11 is placed in the placement groove 10. A baffle 2 is fixed at the top inside the lock cover 1, and the baffle 2 is located inside the second spring 11. The lock head is inserted from the insertion hole 3 above the push block 8, pressing the latch 9. The latch 9 moves backward under the action of the second spring 11, and the rebound force of the second spring 11 pushes the latch 9 out and engages with the lock head for fixation.

[0023] The adjusting lock mechanism also includes a push center plate 21, with a stop plate 26 fixed to its lower end. The rotation of the rotating mechanism presses against the stop plate 26, causing the push center plate 21 to move left and right. A fixed wheel 15 is fixed on the support rod 7, and the fixed wheel 15 corresponds to and matches the position of the push center plate 21. When the push center plate 21 moves, it can drive the fixed wheel 15 to move as a whole. A combination wheel 17 is rotatably mounted on the support rod 7.

A locking groove 16 is opened on the side of the fixed wheel 15, and the locking groove 16 is matched and engaged with the lock plug 14. When the fixed wheel 15 and the push center plate 21 move to one side, the locking block 20 and the teeth 18 disengage. The combination wheel 17 can be rotated to adjust the combination numbers. After adjustment, the push center plate 21 and the fixed wheel 15 are pushed back to their original positions. At this time, the locking block 20 and the teeth 18 are engaged, thereby locking the corresponding numbers and confirming the combination.

[0024] The rotating mechanism includes a rotating plate 23, which is rotatably positioned within the rotating groove 22. A tube 25 is fixed to the lower end of the rotating plate 23, and the tube 25 is correspondingly positioned with the unlocking plate 28. A stop block 24 is fixed to the upper end of the rotating plate 23. The stop block 24 interacts with the stop plate 26 as the rotating plate 23 rotates, thereby driving the central plate 21 to move. A third spring 27 is fixed to the outside of the fixed wheel 15. After the combination wheel 17 is adjusted, when the teeth 18 correspond to the locking block 20, the third spring 27 pushes the whole thing back to its original position for easy operation.
