Description

Technical Field

[0001] This invention relates to the technical field of locks, specifically to a mechanical combination lock, a cabinet, and automated equipment. Background Technology

[0002] The combination lock unlocks by turning the dial, which can still be turned even when the lock is open, making it easy to accidentally touch and cause the combination to be wrong. In addition to the unlocking function, mechanical combination locks also need to have a combination reset function. The combination reset mechanism is set independently from the unlocking mechanism, making the internal structure of mechanical combination locks relatively complex and the operation relatively cumbersome. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a mechanical combination lock that simplifies the unlocking and password reset structures, thereby improving the user experience of the lock.

[0004] This application also proposes a cabinet having the aforementioned mechanical combination lock.

[0005] In addition, this application also proposes an automated device having the aforementioned mechanical combination lock.

[0006] A mechanical combination lock according to a first aspect of the present invention includes a combination disk assembly, a limiting assembly, a pusher, and a lock. The combination disk assembly includes a combination disk and a base disk, which are stacked and rotatably disposed on the same center line. The combination disk has a combination groove, and the base disk has a base groove. The limiting assembly includes a connector, wherein when the combination disk assembly is rotated to the correct combination state, the openings of both the base groove and the combination groove face the connector. The pusher is movably disposed on the side of the connector away from the combination disk assembly, and has a first pusher portion and a second pusher portion. The pusher is movable under external force to align the first pusher portion and the second pusher portion with and push the connector. When the first pusher portion aligns with the connector, the connector can be inserted into the combination groove. When the second pusher portion aligns with the connector, the connector can be inserted into the base groove. The lock is drivenly connected to the pusher. When the combination disk assembly is rotated to the correct combination state and the first pusher portion aligns with the connector, the lock is in an unlocked state.

[0007] The mechanical combination lock according to embodiments of the present invention has at least the following beneficial effects:

[0008] This application embodiment provides two force-applying bodies: a first pushing part and a second pushing part. Under the pushing action of the first pushing part, the connector can be inserted into the combination lock slot to restrict the rotation of the combination dial. The pushing part is connected to the lock mechanism, and this connection allows the pushing part to combine the action of locking the combination dial with the action of unlocking the lock mechanism, thereby preventing the combination dial from being accidentally touched and causing the combination to be incorrect in the unlocked state. Under the pushing action of the second pushing part, the connector can be inserted into the base plate slot to restrict the rotation of the base plate, while the combination dial can rotate normally for combination reset.

[0009] In this embodiment, both the first and second pushing parts are set on the pushing member. The movement range of the pushing member (such as the rotation angle) is adjusted by external force so that the first or second pushing part acts on the plug-in member, thereby braking the combination lock or base plate. The combination lock and combination reset operations can be completed by a single motion mechanism, which significantly simplifies the internal structure of the mechanical combination lock, simplifies the operating principle, and makes it more convenient for users.

According to the rotation of the pushing member, the sliding member can be pushed by the first pushing part and the second pushing part in sequence, thereby driving the plug-in member to slide in a specified direction.

[0013] According to some embodiments of the present invention, the rotation center line of the password disk assembly is parallel to the rotation center line of the pusher, the base disk groove is provided on the circumferential surface of the base disk, and the password disk has two or more password stops protruding on the disk surface facing the base disk. The password stops are arranged circumferentially around the rotation center line of the password disk and are provided on the outer side of the base disk. A password groove is formed between two adjacent password stops.

[0014] According to some embodiments of the present invention, the password disk assembly further includes a swivel mechanism, one end of which is connected to the password disk and the other end of which is connected to the base disk.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0040] Please see Figure 1 and Figure 2 According to some embodiments of the present invention, a mechanical combination lock includes a lock housing 100 and a combination dial assembly 200, a limiting assembly 300, a pushing member 400, and a locking member 500 disposed on the lock housing 100. The lock housing 100 has an inner wall with a mounting shaft 110. The combination dial assembly 200 includes a combination dial 210 and a base plate 220. The combination dial 210 and the base plate 220 are stacked and rotatably mounted on the mounting shaft 110. The dial surfaces of the combination dial 210 and the base plate 220 are parallel to the housing surface of the lock housing 100. The housing surface is opposite to the mounting base plate 120 of the lock housing 100. Therefore, in the use state of the mechanical combination lock, the dial surface of the combination dial 210 will face the user. The dial surface of the combination dial 210 is engraved with several numeric combination options. The numeric combination options are arranged circumferentially around the rotation center line of the combination dial 210. Compared with the method where the circumference of the combination dial 210 faces the user, the orientation of the combination dial 210 in this embodiment allows the user to use two fingers to turn the combination dial 210, making the operation more effortless.

[0041] The circumferential surface of the password disk 210 is provided with a password slot 211, and the circumferential surface of the base disk 220 is provided with a base disk slot 221 (see...). Figure 7 Please refer to... Figure 3The limiting component 300 includes a connector 310, which is movably disposed between the password disk assembly 200 and the pusher 400. When the password disk assembly 200 is rotated to the correct password state, the slots of the base disk groove 221 and the password groove 211 are facing the connector 310. The pusher 400 is disposed on the side of the connector 310 away from the password disk assembly 200, and the pusher 400 is provided with a first pusher part 410 and a second pusher part 420.

[0042] Under the action of external force, the first pushing part 410 and the second pushing part 420 can be aligned with the plug-in 310 and push the plug-in 310, so that the plug-in 310 can be inserted into the password slot 211 or the base plate slot 221. Specifically, under the pushing action of the first pushing part 410, the plug-in 310 can be inserted into the password slot 211 to restrict the rotation of the password disk 210, thereby locking the password disk 210 and preventing the password disk 210 from being confused due to accidental touch. Under the pushing action of the second pushing part 420, the plug-in 310 can be inserted into the base plate slot 221 to restrict the rotation of the base plate 220, while the password disk 210 can rotate normally to reset the password. In this process, the pusher 400 is connected to the lock 500 in a transmission connection. This connection allows the pusher 400 to lock the combination dial 210 while simultaneously unlocking the lock 500, preventing the combination dial 210 from being accidentally touched and causing the combination to be scrambled when it is unlocked.

[0043] Please see Figure 2 The pusher 400 is rotatably disposed on the side of the connector 310 away from the keypad assembly 200. The pusher 400 includes a cylindrical body 430 and a knob portion 440 disposed at the end of the cylindrical body 430. The knob portion 440 and the cylindrical body 430 are coaxially disposed. The first push portion 410 and the second push portion 420 are both disposed on the circumferential surface of the cylindrical body 430. The depth of the first push portion 410 and the depth of the second push portion 420 are not equal. According to this depth setting, the pushable distance of the first push portion 410 and the second push portion 420 is not the same, thereby pushing the connector 310 to different positions. Correspondingly, the depths of the keypad 211 and the base plate groove 221 are also not the same. The connector 310 can be inserted into the keypad 211 or the base plate groove 221 according to different push distances, thereby realizing the locking of the keypad 210 or the base plate 220.

[0044] Please see Figure 4 Specifically, the rotation center line of the password disk assembly 200 is parallel to the rotation center line of the pusher 400, and the base disk groove 221 is provided on the circumferential surface of the base disk 220 (see...). Figure 7 The cipher disk 210 has two or more cipher blocks 230 protruding from its surface facing the base disk 220 (see...). Figure 7The combination blocks 230 are arranged circumferentially around the rotation center line of the combination disk 210, and a combination slot 211 is formed between two adjacent combination blocks 230. The combination blocks 230 are located on the outer side of the base disk 220, so that the combination slot 211 is located outside the base disk slot 221 (see...). Figure 8 ).

[0045] In some embodiments, both the first pushing part 410 and the second pushing part 420 are groove structures provided on the circumferential surface of the cylinder body 430, or the first pushing member 400 is a groove structure and the second pushing member 400 is flush with the circumferential surface of the cylinder body 430. In general, the depth of the first pushing part 410 is greater than the depth of the second pushing part 420. In this embodiment, the insertion depth of the base plate groove 221 is greater than the insertion depth of the password groove 211. The password groove 211 is equivalent to the gap between two adjacent password stops 230. Therefore, the insertion depth of the password groove 211 is determined by the position of the password stops 230. The distance from the password stops 230 to the rotation center line of the password disk assembly 200 is greater than the distance from the bottom of the base plate groove 221 to the rotation center line of the password disk assembly 200.

[0046] According to the above-mentioned dimensional settings, when the connector 310 is pushed by the first pusher 410, the connector 310 will be inserted into the base plate groove 221 at a relatively shallow depth. Furthermore, when the connector 310 is inserted into the circumferential arrangement line of the password stop 230, the connector 310 can simultaneously restrict the rotation of the base plate 220 and the password disk 210, thereby locking the entire password disk assembly 200 and preventing accidental password corruption. When the connector 310 is pushed by the second pusher 410... When the pusher 420 pushes, the connector 310 will be inserted into the base plate slot 221 to a considerable depth. The connector 310 passes through the circumferential arrangement line of the password stop 230, that is, the connector 310 is not on the rotation trajectory of the password stop 230. Therefore, the connector 310 can restrict the rotation of the base plate 220 but cannot restrict the rotation of the password plate 210. In this case, the base plate 220 is locked, the password plate 210 can rotate normally, and the user can perform a password reset operation.

[0047] Understandably, please refer to Figure 8 By pre-designing the dimensions of the connector 310, especially the dimensions of the connector 310 in the direction perpendicular to the surface of the base plate 220, the connector 310 can be made to abut against the password stop 230, thereby effectively braking the password plate 210.

[0048] Additionally, in some other embodiments, the insertion depth of the base plate slot 221 can be set to be less than the insertion depth of the password slot 211. For example, the distance from the password stop 230 to the rotation center line of the password disk assembly 200 is less than the distance from the bottom of the base plate slot 221 to the rotation center line of the password disk assembly 200, making the password stop 230 closer to the rotation center line of the password disk assembly 200 than the base plate slot 221. When the connector 310 is inserted into the base plate slot 221 at a shallow depth, the connector 310 restricts the rotation of the base disk 220 but not the rotation of the password disk 210; this is the password reset state. When the connector 310 is inserted into the base plate slot 221 at a deeper depth, the connector 310 simultaneously restricts the rotation of both the base disk 220 and the password disk 210; this is the password locked state.

[0049] In some implementations, the knob 440, when turned by external force, will cause the cylinder 430 to rotate, thereby stopping the entire combination dial assembly 200 to prevent accidental password touch, or stopping the base 220 to initiate the password reset operation. The lock 500 includes a lock cylinder 510 and a bolt 520 located at the end of the lock cylinder 510. The lock cylinder 510 is rotatably mounted on the lock housing 100 to drive the bolt 520 to rotate, thereby realizing unlocking and locking. The cylinder 430 is sleeved on the lock cylinder 510, and the lock cylinder 510 can rotate with the rotation of the cylinder 430. In this embodiment, the rotation state of the lock 500 is combined with the pushing action by designing the angular relationship between the first pushing part 410, the second pushing part 420 and the bolt 520.

[0050] Specifically, the pusher 400 also includes a third pusher portion 450 recessed in the cylinder body 430, the depth of which is greater than that of the first pusher portion 410 and the second pusher portion 420.

[0051] In such Figure 6 and Figure 7 In the shown state, the pusher 400 is in the initial 0° position, the latch 520 is in the locked position, the third pusher 450 abuts against the slider 320, the connector 310 is on the outside of the combination dial assembly 200, and the combination dial assembly 200 can rotate; Figure 8 and Figure 9 In the shown state, the pusher 400 is in the 180° position, the latch 520 is in the unlocked position, the first pusher 410 abuts against the slider 320, the connector 310 is inserted into the base slot 221 and the combination slot 211, and the combination plate assembly 200 is locked to prevent the combination from being confused; in such a state... Figure 10 and Figure 11In the state shown, the pusher 400 is at the 225° position, the second pusher 420 abuts against the slider 320, the plug 310 is only plugged into the base plate groove 221, the combination plate 210 can rotate, and the mechanical combination lock enters the combination reset state; after resetting the combination, by screwing the pusher 400 back to the 0° position, the combination plate assembly 200 returns to the rotatable state.

[0052] Please see Figure 2 In some embodiments, the end face of the lock cylinder 510 is provided with a keyhole 530 for key insertion, and the peripheral surface of the lock cylinder 510 is provided with a spring hook 540. During the engagement of the pusher 400 and the lock cylinder 510, the spring hook 540 is squeezed by the inner peripheral surface of the cylinder body 430 to generate an elastic force. This elastic force increases the engagement strength between the cylinder body 430 and the lock cylinder 510. Furthermore, because the combination dial assembly 200 rotates to the correct combination state, the base groove 221 will align with the insertion member 310, thus facilitating sliding. The sliding member 320 (see subsequent description for the sliding member 320) provides a sliding space. The sliding member 320 does not obstruct the rotation of the push member 400. Therefore, when the password is correct, the push member 400 can rotate under the action of the turning force. According to the sleeve setting of the push member 400 and the lock cylinder 510, the push member 400 can drive the lock cylinder 510 to rotate to unlock, so that the combination dial 210 can be locked in the unlocked state, avoiding password confusion caused by accidental touch.

[0053] If the combination dial assembly 200 is not correctly turned, or if no combination is entered, the lock cylinder 510 can be unlocked by inserting a key. Specifically, when the torque of the key is greater than the frictional torque generated by the spring hook 540, the lock cylinder 510 slides off the pusher 400 and rotates, thereby driving the bolt 520 to rotate to unlock and lock while the pusher 400 is stationary. With this structural arrangement, the actions of the combination dial assembly 200 and the lock cylinder 510 in this embodiment are independent of each other. The mechanical combination lock can be unlocked using either a combination or a key without affecting each other, enabling emergency unlocking.

[0054] Please see Figure 2 and Figure 3The limiting component 300 also includes a slider 320, which is located on one side of the combination plate assembly 200. The slider 320 can slide in a direction parallel to the surface of the base plate 220. The connector 310 is located on the slider 320, and the end of the slider 320 abuts against the circumferential surface of the cylinder body 430. As the cylinder body 430 rotates, the slider 320 can be pushed sequentially by the first push part 410 and the second push part 420, thereby driving the connector 310 to slide in a specified direction. When the combination plate assembly 200 is rotated to the correct password state, the openings of the base plate groove 221 and the password groove 211 face the connector 310. The connector 310 can move with the slider 320 and slide into the base plate groove 221 or the password groove 211.

[0055] Among them, the sliding member 320 is provided with a guide groove 330 at the end away from the pusher 400. The extension direction of the guide groove 330 is on the same straight line as the center line connecting the combination plate assembly 200 and the cylinder body 430. The inner wall of the lock case 100 is provided with a guide post 340. The guide groove 330 is slidably sleeved on the guide post 340. According to the connection of the guide post 340 and the guide groove 330, after the sliding member 320 is pushed by the pusher 400, it can slide along the direction of the center line connecting the combination plate assembly 200 and the cylinder body 430.

[0056] To ensure the contact strength between the sliding member 320 and the pushing member 400, so that the pushing force can be smoothly transmitted to the plug-in member 310, a slider spring 350 is connected to the end of the sliding member 320 away from the pushing member 400. The slider spring 350 is parallel to the guide groove 330. A positioning post is provided on the inner wall of the lock housing 100. One end of the slider spring 350 is connected to the positioning post, and the other end is connected to the sliding member 320. During the process of pushing the sliding member 320, the slider spring 350 contracts and generates an elastic force on the sliding member 320, thereby causing the sliding member 320 to abut against the pushing member 400 with a relatively strong force.

[0057] Please see Figure 6To prevent the combination disk 210 and base disk 220 from rotating in a vibrating environment and causing code corruption, and to provide users with a more reliable operating feel, the combination disk assembly 200 also includes a hinge mechanism 240. One end of the hinge mechanism 240 is connected to the combination disk 210, and the other end is connected to the base disk 220. The hinge mechanism 240 is used to connect and disconnect the combination disk 210 and the base disk 220. Specifically, the combination disk 210 has a protrusion 241 with a ball head on its surface facing the base disk 220, and the base disk 220 has an arc-shaped recess 242 on its surface facing the combination disk 210. An elastic element 243 is connected to the surface of the base disk 220 facing away from the combination disk 210. The elastic element 243 is used to provide an elastic force to press the base disk 220 and the combination disk 210 together. The protrusion 241 is arranged around the rotation center line of the keypad assembly 200, so when rotating the keypad 210, a solid operating feel is obtained at certain angles. According to the setting of the elastic element 243, the keypad 210 and the base plate 220 will not easily slip off even in a vibration environment. The keypad 210 can only rotate when the torque received by the keypad 210 is greater than the frictional torque generated by the elastic element 243.

[0058] Please see Figure 7 In some embodiments, the mechanical combination lock further includes a combination confirmation mechanism 600. The combination confirmation mechanism 600 includes a first confirmation body and a second confirmation body. The first confirmation body includes a notch 610 on the base plate 220, and the second confirmation body includes an observation window 620. There are two or more observation windows 620, respectively located on the lock housing 100 and the sliding member 320. In the locked state, the combination dial assembly 200 can rotate freely. At this time, the observation window 620 on the sliding member 320 aligns with the observation window 620 on the lock housing 100. The distance from the observation window 620 to the rotation center line of the combination dial assembly 200 is equal to the distance from the notch 610 to the rotation center line of the combination dial assembly 200. When the combination dial assembly 200 is rotated to the correct combination state, the notch 610 aligns with the observation window 620. The user can find the correct combination value by rotating the combination dial assembly 200 while observing whether the observation window 620 is aligned with the notch 610, thus quickly and conveniently retrieving the combination without disassembling the entire lock.

[0059] Understandably, in practical applications, designers can appropriately increase the number of password disk components 200 according to the key quantity requirements. The password disk components 200 are arranged at intervals along the center line connecting the password disk components 200 and the pusher 400, and a corresponding connector 310 is provided on one side of each password disk component 200. Based on the design principle of this scheme, a larger key quantity output can be achieved.

[0060] In summary, the mechanical combination lock of this application embodiment, by cleverly setting a pusher 400 on the circumferential surface of the lock cylinder 510, can realize operations such as locking the combination disc 210 and resetting the combination by controlling the rotation angle of the lock cylinder 510 and the pusher 400. In addition, this application embodiment also provides a movable joint mechanism 240 to prevent the combination disc 210 from slipping out, and a combination confirmation mechanism 600 to significantly reduce the difficulty of retrieval. Therefore, this application embodiment significantly simplifies the internal structure of the mechanical combination lock, simplifies the operating principle, and facilitates user use.
