The present disclosure relates to a lock, and more particularly relates to a dual lock assembly structure that uses a key and a password for locking and unlocking.
Dual lock is a lock using a key and/or a password to achieve the effect of unlocking the lock. A related-art dual lock includes a lock core which is opened by the key, a password mechanism formed by a plurality of number wheels, and a control module linked between the lock core and the password mechanism, in which the control module often requires a complicated structural design to achieve consistent locking and unlocking actions between the lock core and the password mechanism.
In the related-art dual lock, there is often a lack of detail in the overall assembly of the lock due to the above complicated structural design, that is, the related-art lock has a housing formed by a front half and a back half, and each of the above mechanisms or components is configured in the front half or the back half, and then the front half and the back half are engaged and formed into one piece. Such design is likely to result in that the housing compresses the internal mechanisms or components, which affects the smoothness of operation of the internal mechanisms or components, and even affects the smoothness of the operation of the number wheels by the hand. At the same time, the related-art dual lock must be assembled into its housing one by one, thus causing a difficult and time-consuming assembling process, incurring a higher cost, and resulting in a lower yield and a difficult maintenance issue.
In view of the above, the present discloser based on years of experience to conduct extensive research and experiment, and finally provided a reasonable feasible design in accordance with this disclosure to improve the drawbacks of the related art.
The primary objective of the present disclosure is to provide a dual lock assembly structure, which the inside mechanisms or components are assembled in advance and then installed into one housing. As a result, the internal components may be sealed only by covering another housing. The interference caused by the operation of the internal components may be reduced, the smoothness of the operation and hand feel of the components may be maintained, and the assembly of the product may be facilitated.
To achieve the aforementioned objective, the present disclosure provides a dual lock assembly structure, including: a lock housing, having a containing space, a plurality of wheel holes spaced from one another and formed on the lock housing, and a lock core hole disposed adjacent to the wheel holes; a password mechanism, including a wheel pack, a password control module and a lock core control member, the wheel pack including a spindle, a plurality of number wheels passed onto the spindle, and a plurality of wheel barrels disposed on the spindle and corresponding to the number wheels respectively for clutching, the password control module comprising a roller seat and a control plate, the wheel pack being installed on the roller seat, the control plate including a plurality of limiting parts corresponding to an abutting surface of the wheel barrels, and when the abutting surface of each wheel barrel and an opposite side of each limiting part are aligned evenly, the spindle drives each wheel barrel to move along an axial direction; a key lock core, passed into the containing space and fixed to the lock core hole to link a lock lever, and when a key is inserted into the key lock core and drives the lock lever for unlocking or locking, and a knob is sheathed on the key lock core, the knob links a lock plate and drives the lock lever for unlocking or locking; and a closed casing, covered onto an opening of the containing space; wherein, the lock core control member comprises an end part passed to the spindle of the wheel pack, and an interference part abutting against the lock plate of the key lock core, and when the spindle is situated in a state capable of driving each wheel barrel to move along the axial direction, the knob of the key lock core is turned to make the lock plate push away the interference part of the lock core control member.
The technical characteristics of this disclosure will become apparent with the detailed description of preferred embodiments accompanied with the illustration of related drawings as follows. It is noteworthy that the embodiments and drawings disclosed herein are to be considered illustrative rather than restrictive.
With reference to
The lock housing 1 is provided for installing the password mechanism 2 and the key lock core 3. In a specific embodiment, after the password mechanism 2 and the key lock core 3 are assembled, they are installed in the lock housing 1 directly to obtain the aforementioned structural positioning. In
In
The lock core control member 22 has a plurality of front wheel holes 220a corresponding to the number wheels 201 respectively, and installed at the front end of the roller seat 210 of the password control module 21. The lock core control member 22 and the control plate 211 of the password control module 21 are clamped by the front end of the roller seat 210 and the rear end of the wheel pack 20, so as to assemble the password mechanism 2 as one piece, which is installed together with the key lock core 3 into the containing space 12 of the lock housing 1, and finally the closed casing 4 covers the opening of the containing space 12 of the lock housing 1 to complete the dual lock assembly structure of the present disclosure.
In
When a user forgets the password, the user may insert a correct key into the lock core 3 to turn the knob 31 directly to abut the lock plate 32 against the end 220b, so as to drive the lock core control member 22 to make the spindle 200 move in the aforementioned axial direction and each wheel barrel 202 compresses the corresponding elastic element 204. At this time, the number wheels 201 are dialed one by one. Until the wheel barrel 202 of each corresponding number wheel 201 is dialed to a position where the abutting surface 202a is aligned precisely with a side of each limiting part 211b, the wheel barrel 202 is bounced back by the compressed elastic element 204. After the wheel barrels 202a are bounced back one by one, the corresponding number of each number wheel 201 constitutes the correct password. Of course, the correct password is retrievable or the password is resettable to a new password by inserting the aforementioned correct key into the lock core 3. In
With the above structural assembly, the dual lock assembly structure of the present disclosure is achieved.
Therefore, the present disclosure assembles and modularizes the password mechanism 2, and installs it together with other mechanisms or components (such as the key lock core 3) inside the dual lock into the lock housing 1, so that the closed casing 4 only needs to be covered onto the lock housing 1 in order to complete the assembly and achieve the effects of reducing the interference effect of the lock housing or the closed housing on the password mechanism to maintain its smoothness in operation and handfeel, while facilitating the assembly of the product. The present disclosure is conducive to the improvement of existing issues of the time-consuming, high-cost, low-yield and uneasy-maintenance lock structure.
While the disclosure is described in some detail hereinbelow with reference to certain illustrated embodiments and accompanying drawings, it is to be understood that there is no intent to limit it to those embodiments. On the contrary, the aim is to cover all modifications, alternatives and equivalents falling within the spirit and scope of the invention as defined by the appended claims.
