Description
Technical Field
[0001] The utility model relates to the technical field of door lock hardware. Specifically, the utility model relates to a minimalist door lock. Background Art
[0002] As the name implies, a door lock is a device used to lock a door to prevent others from opening it. There are many classifications of door locks, and the requirements for door locks vary in different occasions. Ordinary families generally use anti-theft door locks, which are highly secure and relatively inexpensive. Door locks can be classified into spherical door locks, three-rod handle locks, mortise handle locks, glass door locks, etc. according to different lock-making technologies and applications. The commonly used handle lock is generally composed of structures such as a housing, a handle, a lock core, and a lock core seat, and is usually opened and closed by rotating the handle.
[0003] However, the door locks currently used on doors usually rotate at the connection between the handle and the lock core to achieve opening and locking, with complex structures, large space occupation, and troublesome operations.
[0004] The utility model patent announcement text with the patent application number 202323048262.9 discloses an invention creation named an integrated minimalist door lock. For this minimalist door lock, the lock core component can be inserted into the door panel from the side panel of the door panel, and only the inner handle and the outer handle are exposed on both the inside and outside of the door panel. The installation structure is simple and the operation is convenient. In the lock core of this minimalist door lock, a notch is provided at one end of the rotating ring 307, the operating ring 309 is sleeved at the corresponding position of the notch, and a card slot 311 is provided. When the block of the handle push rod enters, the card slot can hold the block, so that the operating ring can rotate synchronously with the rotation of the rotating ring and act on the lock tongue to achieve the locking and unlocking of the door lock. When the block is not in the card slot, the operating ring and the rotating ring rotate relative to each other to achieve the clutch function.

[0033] It should be noted that the concepts such as "first" and "second" mentioned in the present utility model are only used to distinguish devices, modules or units, and are not used to limit that these devices, modules or units must be different devices, modules or units, nor are they used to limit the order or mutual dependence relationship of the functions performed by these devices, modules or units.
[0034] See Figures 1 to 10The utility model provides a minimalist door lock, including a lock core 100, a lock core 100 seat, a rotating shaft 70 and a handle 300, wherein the lock core 100 is inserted into a pre-opened installation groove on one of the left and right sides of a door panel 400, the lock core 100 seat is installed on the door frame and can be used for the lock tongue of the lock core 100 to lock the door, the rotating shaft 70 is passed through the lock core 100 and exposed on the front and rear sides of the door panel, the handle is disposed on the part where the rotating shaft 70 passes through, and can drive the rotating shaft 70 to rotate, thereby realizing the extension and retraction of the lock tongue of the lock core 100. Since only the handle of the door lock is exposed outside the door panel, the door lock installation structure is simple, has an excellent visual effect, and is conducive to improving the user experience.
[0035] In one embodiment, the lock core 100 includes a housing 10, and a rotating shaft sleeve 20, an operating block 30, an operating ring 40 and a lock tongue assembly 50, all of which are arranged on the housing 10, wherein a clutch assembly is formed between the operating block 30, the operating ring 40, the rotating shaft sleeve 20 and the rotating shaft 70 to realize a clutch function, specifically, the lock tongue does not move when the handle is rotated.
[0036] The housing 10 includes a first housing 11 and a second housing 12 assembled with the first housing 11 . The first housing 11 and the second housing 12 are both provided with a shaft clearance hole 13 . The shaft clearance holes 13 of the first and second housings 12 are arranged opposite to each other for allowing the shaft 70 to pass through.
[0037] The rotating shaft sleeve 20 is provided with a rotating shaft hole 21 that passes through both ends, and a mounting notch 22 is provided on the side of the rotating shaft sleeve 20 at the middle position of the axial direction. The rotating shaft sleeve 20 is arranged in the housing 10 in such a way that the rotating shaft hole 21 is aligned with the rotating shaft clearance hole 13. A slide groove 71 is provided on the upward side of the rotating shaft 70, and a push rod 72 with a clamping block 723 is slidably provided in the slide groove 71. The rotating shaft 70 is passed through the rotating shaft hole 21 of the rotating shaft sleeve 20, and its two ends pass through the rotating shaft clearance hole 13 of the housing 10, and the handle is provided on the part where the rotating shaft 70 passes through. It can be understood that the rotating shaft 70 is tightly matched with the rotating shaft sleeve 20, so that the rotating shaft 70 and the rotating shaft sleeve 20 rotate synchronously.
[0038] The operating block 30 is rotatably embedded in the installation notch 22. A downward-opening slot 311 is provided at the lower end of the operating block 30. The slot 311 is communicated with the rotating shaft hole 21, and the block 723 on the push rod 72 can be clamped when it moves along the rotating shaft hole 21 into the slot 311, so that the operating block 30 can rotate synchronously when the rotating shaft 70 rotates.
[0039] The control ring 40 is sleeved on the rotating shaft sleeve 20. One end of the control ring 40 is clamped with the control block 30 and can be driven by the control block 30 to rotate relative to the rotating shaft sleeve 20. A push block 41 is provided at the top end of the outer periphery of the control ring 40. The push block 41 can act on the lock tongue assembly 50 when the control ring 40 rotates to make the lock tongue move laterally.
[0040] The working principle of the minimalist door lock of the present utility model is as follows:
[0041] When it is necessary to lock the door lock, the push rod 72 on the rotating shaft 70 is pushed, so that the clamping block 723 fixed on the push rod 72 moves along the rotating shaft hole 21 into the card slot 311 of the control block 30. The door handle is rotated, so that the rotating shaft 70 drives the rotating shaft sleeve 20 to rotate, and then drives the control ring 40 to rotate through the control block 30, so that the push block 41 of the control ring 40 applies force to the lock tongue assembly 50, and the lock tongue moves laterally into the lock core 100 seat, realizing the locking of the door lock.
[0042] When the push rod 72 is pushed in the reverse direction and the clamping block 723 on the push rod 72 is removed from the card slot 311 of the control block 30, at this time, even if the rotating shaft sleeve 20 rotates when the door handle rotates, the control block 30 and the control ring 40 do not rotate (the control block 30 and the control ring 40 rotate relative to the rotating shaft sleeve 20), and the lock tongue does not move laterally, realizing the locking of the door lock.
[0043] Therefore, in the present utility model, by providing an installation notch 22 at the middle position on the side of the rotating shaft sleeve 20, the control ring 40 and the control block 30 are separately arranged. The control block 30 is rotatably embedded in the installation notch 22, and the control ring 40 is inserted into the control block 30 from one side and clamped with the control block 30, which can avoid the limitation of the existing lock core 100 on the left-opening door lock and the right-opening door lock, realize the universal function of the lock core accessories on the left-opening door lock and the right-opening door lock, that is, using a set of lock core 100 accessories can meet the use of the left-opening door lock and the right-opening door lock, expand the use range of the lock core 100, save the production cost of the lock, facilitate the installation of the lock, and improve the user experience.
