Description

Technical Field

[0001] The utility model relates to the field of password locks, in particular to a rotary disk password lock with an anti-mistouch function. Background Art

[0002] A combination lock is a type of lock that uses a series of numbers or symbols to open. Combination locks can be divided into mechanical combination locks and electronic combination locks. Mechanical combination locks generally rely on turning a combination wheel to enter the password, while electronic combination locks use buttons or touch screens to enter the password.

[0003] Among the existing mechanical combination locks on the market, there is a rotary dial combination lock. The structure of this rotary dial combination lock generally includes a panel with a combination wheel and a knob rotatable relative to the panel. The rotary dial combination lock only needs to dial the combination wheel to enter the correct password and then turn the knob to complete the unlocking. This combination lock is easy to operate and its size is smaller than other mechanical combination locks. Therefore, the rotary dial combination lock is widely used on cabinet doors;

[0004] In order to prevent users from forgetting their passwords, common rotary dial combination locks on the market are equipped with an additional mechanical lock cylinder. By inserting the key into the lock cylinder to unlock it, the code-finding structure in the combination lock can be triggered, and then the code-finding operation can be performed by turning the combination wheel to retrieve the correct password.

[0005] Among them, the Chinese patent application with patent number ZL201920579529.1 disclosed: "A turntable combination lock, comprising a shell, the shell comprising a combination lock, a key lock and a knob, the key lock comprising a lock core and a lock tongue plate arranged on the knob and used to lock or unlock the rotation state of the knob, the combination lock comprising a combination wheel and a number changing block, the combination wheel and the number changing block are detachably engaged, the knob is cooperatively connected with a lock plate, the lock plate is provided with an abutment end abutting the number changing block, when the combination wheel and the number changing block are in an engaged state, the knob can be rotated to force the abutment end to squeeze the number changing block, so that the number changing block rotates and resets".

[0006] However, including the solution described in the above patent, there is a problem in the prior art rotary combination locks, that is, the lock core used in the combination lock to trigger the code-finding function has an unlocking rotation angle of 90°, and the key of the conventional lock core in the prior art is inserted horizontally into the lock core to facilitate turning the key, which results in the key turning 90° when used in the rotary combination lock.

[0007] This also results in the minimum distance between the handle of the key and the code wheel on the panel after the lock cylinder is unlocked. When searching for the code by turning the code wheel, it is easy to accidentally touch the key, causing the key to turn the lock cylinder and relock it, interrupting the code search process. Summary of the invention

[0008] In order to overcome the disadvantage of the prior art that the key is easily touched by mistake during the code-searching process after the lock core is unlocked, resulting in the forced interruption of the code-searching process, the utility model provides a rotary disk code lock with an anti-mistouch function.

[0009] The utility model solves the technical problem by providing a rotary dial combination lock with an anti-accidental touch function, comprising:

[0010] A housing, comprising a panel and a fixing seat;

[0011] A knob is rotatably mounted on the outer side of the housing, and a locking plate is connected to the knob. The locking plate can rotate with the knob to achieve locking or unlocking;

[0012] A cipher wheel assembly is arranged in the housing, the cipher wheel assembly includes a spindle and a plurality of character wheels rotatably sleeved on the spindle, the spindle can act on the knob to prevent the knob from rotating, and the character wheels pass through the panel and are exposed on the front side of the panel;

[0013] A code-finding component is located in the housing. The code-finding component includes a code-finding member and a driving member. The code-finding member can move under the driving of the driving member. The code-finding member moves closer to or away from the character wheel to achieve interference with or release of the rotation of the character wheel.

[0014] A lock core is rotatably disposed in the housing, a top portion of the lock core having a lock hole passing through the panel and exposed to the front side of the panel, and the drive member is in transmission connection with the lock core;

[0015] A key is inserted into the lock core and rotated to rotate the lock core to drive the driving member to move. When the key is inserted into the lock core, there is a gap between the key handle exposed on the front side of the panel and the character wheel exposed on the front side of the panel, and the gap increases or decreases with the rotation of the key;

[0016] The key has at least a locked position and an unlocked position by rotation, and when the key is in the unlocked position, the distance between the key handle and the character wheel is the maximum distance.

[0017] The specific rotation angle of the key and its states before and after rotation are further described. The rotation angle of the key between the locked position state and the unlocked position state is 180°, so that when the key is in the locked position state and in the unlocked position state, the distance between the key handle and the character wheel is the maximum distance.

[0018] The transmission connection method between the lock core and the driving member is further: a movable groove is arranged in the shell, and the driving member is a driving plate which can be translatedly arranged in the movable groove. An eccentric column is protrudingly provided at the bottom of the lock core, and a sliding groove is opened on the driving plate. The eccentric column is inserted in the sliding groove and can slide relative to the sliding groove. The rotation of the lock core can drive the driving plate to translate through the eccentric column, so that the driving plate is close to or away from the code finding member.

[0019] The specific structure of the code-seeking member is further that the code-seeking member includes a shaft portion and a claw portion, the code-seeking member is rotatably connected to the shell through the shaft portion, the claw portion is used to form an interference fit with the character wheel, and an abutment column is protruding downward on the rod portion of the code-seeking member, and an abutment rib is protruding on the drive plate for forming an abutment fit with the abutment column.

[0020] The reset structure of the code-seeking member is further characterized in that a reset spring is sandwiched between the shell and the code-seeking member in the shell, and the reset spring acts on the code-seeking member so that the code-seeking member always has a movement tendency away from the code wheel assembly.

[0021] The specific structure of the cipher wheel assembly is further that the cipher wheel assembly also includes a plurality of coupling wheels rotatably mounted on the core shaft, the coupling wheels are transmission-connected with the character wheel, a slot is provided on the coupling wheel, a block is convexly provided on the code-seeking member, when the character wheel is turned to drive the slot on the coupling wheel to align with the block, and when the code-seeking member is driven by the driving member to approach the cipher wheel assembly, the block can be engaged with the slot to prevent the character wheel from rotating relative to the core shaft.

[0022] The movement mode of the core shaft relative to the character wheel and the coupling wheel is further improved, the core shaft is provided with a plurality of locking blocks, and the coupling wheel is provided with a plurality of avoidance grooves;

[0023] Before the correct password is input by turning the character wheel, the locking block is staggered with the avoidance groove, and the locking block abuts against the side of the coupling wheel, thereby preventing the core shaft from translating, so that the knob cannot be turned;

[0024] When the correct password is input by turning the character wheel, the locking block is aligned with the avoidance groove. At this time, turning the knob can drive the core shaft to translate and make the locking block snap-fit ​​into the avoidance groove.

[0025] The specific matching structure between the core shaft and the knob is further that a lock tongue is provided at one end of the core shaft, and a lock groove is provided on the inner wall of the knob, and the lock tongue can be snap-fitted in the lock groove to prevent the knob from rotating. After the correct password is entered by turning the character wheel, rotating the knob can drive the core shaft to translate and move away from the knob, so that the snap-fitting between the lock tongue and the lock groove is released.

[0026] The reset structure of the spindle is further characterized in that a push block is provided at the other end of the spindle, and a locking spring is sandwiched between the push block and the spindle. The locking spring acts on the spindle to make it always have a movement tendency to approach the knob.

[0027] The specific installation method of the password wheel assembly and the code-seeking assembly in the shell is further as follows: a movable seat is provided in the shell, and the movable groove is opened on the movable seat. A support plate is also connected between the panel and the mounting seat in the shell, and the password wheel assembly and the code-seeking assembly are both installed and connected to the support plate, and the movable seat is also connected to the support plate.

[0028] The specific unlocking and code finding process in the utility model:

[0029] When unlocking, after inputting the correct password by turning the character wheel exposed on the panel surface, all the coupling wheels are driven by the character wheel to rotate until the avoidance groove on them is aligned with the lock block on the core shaft. At this time, turn the knob, the knob can push the core shaft to translate, and the lock block retreats into the avoidance groove on the coupling wheel. At the same time, the lock tongue also disengages from the lock groove on the knob, thereby releasing the lock on the knob rotation. After the knob is turned, it can drive the lock plate to rotate to complete the unlocking;

[0030] When searching for the code, the key is inserted into the lock core and rotated so that the key rotates from the locked position to the unlocked position, and the lock core also rotates accordingly. The eccentric shaft on the lock core pushes the driving plate to translate in the direction close to the code-seeking member, and the abutment ribs on the driving plate abut against the abutment columns on the code-seeking member, thereby pushing the code-seeking member to swing, and the claw of the code-seeking member is able to approach the direction close to the password wheel assembly. At this time, one of the character wheels can be moved with a finger. When the character wheel rotates to the correct number, the card slot on the coupling wheel is aligned with the card block on the claw. Since the claw approaches the password wheel assembly under the action of the driving member, the card block is able to be snapped into the card slot, completing the rotation locking of this character wheel. When the operator feels that the rotation of the character wheel is blocked, he can know that the character wheel has rotated to the correct number, and can continue to complete the rotation and code searching of the remaining character wheels. When the code searching of all the character wheels is completed, the correct password can be obtained.

[0031] The beneficial effects of the utility model are:

[0032] 1. By adjusting the rotation angle of the key used to unlock the lock cylinder, a gap can be formed between the key handle and the character wheel. When the lock cylinder is unlocked by turning the key, the gap between the key handle and the character wheel reaches the maximum gap, which can ensure that the key handle is not accidentally touched during the code search process by turning the character wheel. This effectively prevents the key from being reset by accident and causing the code search to be interrupted.

[0033] 2. The driving mode between the lock core and the code-finding member has been adjusted. The eccentric wheel and the translationally movable driving plate are used to drive the code-finding member, which can better adapt to the process of key rotation unlocking;

[0034] 3. Set the rotation angle required for key unlocking to 180°, so as to ensure that the key handle is in a horizontal state when the key is just inserted and after being turned to unlock, so that the distance between the key handle and the character wheel is maintained at the maximum distance at these two time points, which is convenient for the operator to operate.

An abutment column 22 is also protruded downward on the rod portion of the code-seeking member 12, and an abutment rib 23 is protruded on the drive plate 19 for forming an abutment fit with the abutment column 22.

[0054] Combination Figure 4 and Figure 7 As shown, in the present embodiment, a reset spring 24 is sandwiched between the housing and the code seeker 12 in the housing. The reset spring 24 acts on the code seeker 12 so that the code seeker 12 always has a movement tendency away from the code wheel assembly 5 .

[0057] Among them Fig.11As shown in the figure, in this embodiment, the avoidance groove 29 and the card slot 26 are in the same direction and are both facing downward, and the locking block 28 and the card block 27 are also in the same direction and are both facing upward. Therefore, when the character wheel 7 is rotated to drive the card slot 26 on the coupling wheel 25 to align with the card block 27, the avoidance groove 29 is also aligned with the locking block 28. Therefore, when the card block 27 can be snapped into the card slot 26, the character wheel 7 corresponding to the coupling wheel 25 is in the correct password.

[0058] Combination Figure 6 and Fig.10 As shown, in this embodiment, a lock tongue 8 is provided at one end of the core shaft 6, and a lock groove 9 is provided on the inner wall of the knob 3.

[0062] Combination Figure 2 and Fig.10 As shown, in this embodiment, a spring piece 34 is further provided in the housing, and a plurality of gear slots 35 are provided on the character wheel 7. The spring piece of the spring piece 34 is engaged with one of the gear slots 35, and as the character wheel 7 rotates, the spring piece of the spring piece 34 can move from one gear slot 35 to the next gear slot 35, so as to improve the hand feeling of the user when turning the character wheel 7.

[0063] The specific unlocking and code finding process in this embodiment:

[0064] When unlocking, after inputting the correct password by turning the character wheel 7 exposed on the surface of the panel 1, all the coupling wheels 25 are driven by the character wheel 7 to rotate until the avoidance groove 29 thereon is aligned with the lock block 28 on the spindle 6. At this time, the knob 3 is turned, and the knob 3 can push the spindle 6 to translate. At the same time, the lock block 28 retreats into the avoidance groove 29 on the coupling wheel 25, and the lock tongue 8 also disengages from the lock groove 9 on the knob 3, thereby releasing the lock on the rotation of the knob 3. After the knob 3 is turned, it can drive the lock plate 4 to rotate to complete the unlocking.

[0065] When searching for the code, the key 15 is inserted into the lock cylinder 10 and rotated, so that the key 15 is rotated from the locked position state a to the unlocked position state b, and the lock cylinder 10 is rotated accordingly. The eccentric shaft on the lock cylinder 10 pushes the driving plate 19 to translate in the direction close to the code-seeking member 12, and the abutting rib 23 on the driving plate 19 abuts against the abutting column 22 on the code-seeking member 12, thereby pushing the code-seeking member 12 to swing, and the claw portion 14 of the code-seeking member 12 is able to move closer to the direction close to the code wheel assembly 5. At this time, one of the keys can be moved by a finger. When the character wheel 7 rotates to the correct number, the card slot 26 on the coupling wheel 25 is aligned with the card block 27 on the claw 14. Because the claw 14 is close to the password wheel assembly 5 under the action of the driving member, the card block 27 can be snapped into the card slot 26 to complete the rotation locking of the character wheel 7. When the operator feels that the rotation of the character wheel 7 is blocked, he can know that the character wheel 7 has rotated to the correct number, and can continue to complete the rotation and code search of the remaining character wheels 7. When the code search of all the character wheels 7 is completed, the correct password can be obtained.

[0066] The advantage of this embodiment is that after the key of the rotary combination lock is rotated to unlock the lock cylinder, the distance between it and the character wheel on the panel is the maximum distance, thereby ensuring that the user will not accidentally touch the key and cause it to rotate and reset when turning the character wheel to find the code.

[0067] The above specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
