Description

Technical Field

[0001] This utility model relates to the technical field of door locks, specifically to a hole-free glass door lock. Background Technology

[0002] In existing technologies, the linkage between the front and rear lock bodies of a door lock is crucial to ensuring the consistency of lock operation, especially in special scenarios such as door panels, where it is necessary to balance linkage reliability with installation compactness.

[0003] Currently, most common electronic door locks use a transmission structure along the width of the lock body for linkage between the front and rear lock bodies. This is achieved through toothed plates within the front and rear lock bodies, connected by a steel belt or other connecting components. Specifically, the first toothed plate in the front lock body and the second toothed plate in the rear lock body move horizontally along the width of the clamping plate. The two ends of the steel belt are connected to the two toothed plates respectively. When the first toothed plate is driven to move, the steel belt drives the second toothed plate to move synchronously, thus achieving the linkage operation of the front and rear lock bodies.

[0004] In order to ensure that the first and second toothed plates can move smoothly in the lateral direction of the clamp width and achieve effective linkage between them through the steel belt, the outer and inner lock bodies of the door panel electronic lock need to reserve enough space for the movement of the first and second toothed plates in the internal structural design. This makes the size of the product in the internal width direction increase accordingly, which may lead to the overall structure of the lock body not being compact enough. Utility Model Content

[0005] This invention proposes a hole-free glass door lock, in which the first and second linkage components are designed to move up and down along the height of the lock, changing the transmission method of the toothed plate moving along the width direction in the prior art. This height-direction movable design eliminates the need to reserve a large amount of space in the width direction of the lock body for component movement, effectively reducing the size of the lock body in the width direction and making the overall structure of the lock body more compact.

[0006] A hole-free glass door lock designed for this purpose includes a front door lock body, a rear door lock body, and a linkage assembly. The linkage assembly includes a first linkage component, a second linkage component, and a transmission component. The first linkage component includes a first connecting block, a second connecting block, and a rigid linkage plate. The first connecting block is disposed inside the front door lock body and is connected to the operating part of the front door lock body in a transmission manner; the second linkage is disposed inside the rear door lock body and is connected to the operating part of the rear door lock body in a transmission manner; the second connecting block is disposed inside the rear door lock body and is driven by the transmission member and the second linkage. The first connecting block and the second connecting block extend to the outer sides of the front door lock body and the rear door lock body, respectively, and are simultaneously linked with the rigid linkage plate. When either the first or second linkage component moves up or down under the drive of the corresponding door lock body, it drives the other linkage component to move synchronously in the opposite direction through the meshing of the transmission component, thereby realizing the linkage operation of the front and rear lock bodies.

[0007] The front door lock body is provided with a front operation component, which is drivenly connected to the first connecting block of the first linkage component. The second connecting block and the second linkage component are respectively engaged and drivenly connected to the transmission component. The rear door lock body is provided with a rear operation component, which is drivenly connected to the second linkage component, so that the front operation component and the rear operation component can form a linkage operation.

[0008] The first connecting block is provided with a first rack for drive connection with the front operating component; The second connecting block is provided with a second rack for meshing with a transmission component, which is a transmission gear; The second linkage is provided with a third rack for engaging with the transmission component and for driving connection with the rear operating component; A gear transmission assembly is provided between the front operating component and the first connecting block of the first linkage component.

[0009] Both the first connecting block and the second connecting block of the first linkage are provided with a first limiting strip groove for limiting the vertical displacement of the first linkage. The first limiting strip groove is vertically arranged on the first linkage. The second linkage component is provided with a second limiting strip groove for limiting the vertical displacement of the second linkage component. The second limiting strip groove is vertically arranged on the second linkage component.

[0010] The first connecting block and the second connecting block are arranged at a distance from each other and are provided with rigid linkage plates. The first connecting block and the second connecting block move synchronously through the rigid linkage plates. A bracket is provided between the front door lock body and the rear door lock body. The bracket includes a first mounting block fixedly installed inside the front door lock body, a second mounting block fixedly installed inside the rear door lock body, and a limiting block fixed between the first mounting block and the second mounting block. The bracket and the first linkage component both have one end protruding and are disposed on the outer side of the front door lock body and the rear door lock body, respectively. The rigid linkage plate is positioned between the limiting block and the outer sides of the front and rear door lock bodies, and a clamping groove for clamping the door panel is provided between the front door lock body and the rear door lock body. The limiting block is provided with an abutment block that protrudes in the direction of door panel installation, and the abutment block is used to abut against the side of the door panel; The distance between the inner end face of the limiting block and the inner end face of the abutment block is greater than the thickness of the rigid linkage piece to prevent interference between the door panel and the rigid linkage piece. The first mounting block, the second mounting block, the limiting block, the abutting block, and the door panel together form an enclosed area with openings at both the top and bottom, and the linkage is located within the enclosed area; The main body of the front door lock is located on the outside of the door panel, and the main body of the rear door lock is located on the inside of the door panel.

[0011] The first connecting block, the second connecting block, and the rigid linkage plate together constitute a U-shaped linkage component; The first linkage component in the U-shape is a steel sheet with a thickness of 1mm to 3mm; During the movement of the U-shaped linkage, the two ends of the linkage are relatively stationary, and its first connecting block and second connecting block move synchronously upward or downward. The first connecting block has protrusions on its side to reduce wear.

[0012] The second mounting block of the bracket is provided with a locking tongue assembly that can be moved laterally. The second mounting block is provided with a swing block. The first end of the swing block acts on the locking tongue assembly, the second end of the swing block is rotatably connected to the second mounting block, and the second end of the swing block is connected to the rear operating assembly for transmission. The rear operation component drives the swing block to act on the latch assembly, so that the latch assembly can perform a retracting action. The front operating component is linked with the rear operating component through the linkage assembly to drive the latch component to extend or retract.

[0013] The latch assembly is provided with a third limiting groove for limiting the lateral extension and retraction displacement of the latch assembly. The third limiting groove is laterally arranged on the latch assembly.

[0014] The rear door lock body has a telescopic clearance opening at one end of the latch assembly.

[0015] The latch assembly is provided with a slot, and the first end of the swing block extends into the slot of the latch assembly. During the swinging process, the swing block acts on the inner side of the slot to drive the latch assembly to move. The rear operating component is provided with a first gear that is connected to the swing block drive.

[0016] The front or rear operation component can be a voice recognition, fingerprint recognition, facial recognition, or manual operation component.

[0017] The beneficial technical effects of this utility model are as follows: (1) The first and second linkage components are designed to move up and down along the height of the lock, which changes the transmission method of the toothed plate moving along the width direction in the prior art. This design of movement along the height direction does not require a large amount of space to be reserved for component movement in the width direction of the lock body, effectively reducing the size of the lock body in the width direction and making the overall structure of the lock body more compact. At the same time, the first and second linkage components are driven by meshing transmission components. Compared with steel belt transmission, the meshing transmission has stronger stability and is less prone to slippage or loosening.

[0018] (2) The first linkage component includes a first connecting block, a second connecting block and a rigid linkage plate. The first and second connecting blocks are located in the front and rear door lock bodies respectively. The rigid linkage plate is located on the outside of the door lock body and is linked with the first and second connecting blocks. The rigid linkage plate bypasses the door body and moves on the side of the door body (door seam), thus eliminating the need to open holes in the glass door body. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0031] See Figures 1-11 A hole-free glass door lock includes a front door lock body 1, a rear door lock body 2, and a linkage assembly 3. The linkage assembly 3 includes a first linkage 8, a second linkage 9, and a transmission component 7. The first linkage 8 includes a first connecting block 10, a second connecting block 11, and a rigid linkage plate 18. The first connecting block 10 is disposed inside the front door lock body 1 and is connected to the operating part of the front door lock body 1 in a transmission manner; the second linkage 9 is disposed inside the rear door lock body 2 and is connected to the operating part of the rear door lock body 2 in a transmission manner; the second connecting block 11 is disposed inside the rear door lock body 2 and is driven by the transmission member 7 and the second linkage 9. The first connecting block 10 and the second connecting block 11 extend to the outer sides of the front door lock body 1 and the rear door lock body 2, respectively, and are simultaneously linked to the rigid linkage piece 18. When either the first linkage 8 or the second linkage 9 is driven up and down by the corresponding door lock body, it drives the other linkage to move synchronously in the opposite direction through the meshing transmission of the transmission component 7, thereby realizing the linkage operation of the front and rear lock bodies.

[0032] The first linkage 8 and the second linkage 9 are designed to move up and down along the height of the lock, changing the transmission method in the prior art where the toothed plate moves along the width. This height-moving design eliminates the need for a large amount of space in the width direction of the lock body for component movement, effectively reducing the size of the lock body in the width direction and making the overall structure of the lock body more compact. At the same time, the first linkage 8 and the second linkage 9 are driven by the meshing of the transmission component 7. Compared with steel belt transmission, the meshing transmission has stronger stability and is less prone to slippage or loosening.

[0033] The front door lock body 1 is provided with a front operation component 5, which is drivenly connected to the first connecting block 10 of the first linkage member 8. The second connecting block 11 and the second linkage member 9 are respectively engaged and drivenly connected to the transmission member 7. The rear door lock body 2 is provided with a rear operation component 6, which is drivenly connected to the second linkage member 9, so that the front operation component 5 and the rear operation component 6 form a linkage operation.

[0034] The first connecting block 10 of the first linkage 8 is installed inside the front door lock body 1, and the second connecting block 11 is installed inside the rear door lock body 2, enabling the first linkage 8 to stably transmit power between the front and rear door lock bodies. The front operating component 5 is drivenly connected to the first connecting block 10, the second connecting block 11 is drivenly connected to the second linkage 9 through the transmission component 7, and the rear operating component 6 is drivenly connected to the second linkage 9, forming a clear and stable transmission path.

[0035] The first connecting block 10 is provided with a first rack 13 for transmission connection with the front operating component 5; The second connecting block 11 is provided with a second rack 14 for meshing with the transmission component 7, the transmission component 7 being a transmission gear; The second linkage 9 is provided with a third rack 15 for engaging with the transmission component 7 and for driving connection with the rear operation component 6; A gear transmission group 31 is provided between the front operation component 5 and the first connecting block 10 of the first linkage component 8. The front operation component 5 is connected to the first connecting block 10 through the gear transmission group 31, and the first connecting block 10 is connected to the output end of the gear transmission group 31 through the first rack 13.

[0036] The meshing of the first rack 13 of the first connecting block 10, the second rack 14 of the second connecting block 11, and the third rack 15 of the second linkage 9 with the transmission gear constitutes a multi-set gear and rack transmission structure. This rigid transmission method has higher transmission efficiency and precision compared to the steel belt transmission in the prior art. The gear and rack meshing transmission is not prone to elastic deformation, which can ensure that the movement of the first linkage 8 and the second linkage 9 is completely synchronized, avoiding transmission lag or misalignment, and ensuring the consistency of the linkage operation of the front and rear lock bodies. The gear transmission group 31 set between the front operating component 5 and the first connecting block 10 can optimize the power transmission direction, so that the driving force of the front operating component 5 can be transmitted to the first linkage 8 more smoothly.

[0037] The first connecting block 10 and the second connecting block 11 of the first linkage member 8 are each provided with a first limiting strip groove 16 for limiting the vertical displacement of the first linkage member 8. The first limiting strip groove 16 is vertically arranged on the first linkage member 8. The second linkage member 9 is provided with a second limiting strip groove 17 for limiting the vertical displacement of the second linkage member 9. The second limiting strip groove 17 is vertically arranged on the second linkage member 9.

[0038] The first limiting groove 16 on the first connecting block 10 and the second connecting block 11 of the first linkage member 8, and the second limiting groove 17 on the second linkage member 9, are both vertically oriented, effectively limiting the vertical movement of the first linkage member 8 and the second linkage member 9. This limiting design prevents the linkage members from colliding or interfering with other components in the lock body due to excessive movement, avoiding damage to components and acting as a protective device. Simultaneously, the limiting grooves ensure that the first linkage member 8 and the second linkage member 9 always move within a preset trajectory, ensuring stable meshing with the transmission member 7 and preventing issues such as tooth disengagement, thus maintaining the reliability of the linkage transmission. Furthermore, the limiting groove structure is simple, eliminating the need for additional complex limiting components, saving internal space in the lock body and reducing production costs. Moreover, the clear travel limitation provides clear feedback to the user during operation, improving the operating feel and preventing unnecessary damage to the lock due to excessive operation.

[0039] The first connecting block 10 and the second connecting block 11 are arranged at a distance from each other and are provided with a rigid linkage plate 18. The first connecting block 10 and the second connecting block 11 move synchronously through the rigid linkage plate 18. A bracket 19 is provided between the front door lock body 1 and the rear door lock body 2. The bracket 19 includes a first mounting block 20 fixedly installed in the front door lock body 1, a second mounting block 21 fixedly installed in the rear door lock body 2, and a limiting block 22 fixed between the first mounting block 20 and the second mounting block 21. The bracket 19 and the first linkage 8 both have one end protruding and are disposed on the outer side of the front door lock body 1 and the rear door lock body 2; The rigid linkage plate 18 is limited between the limiting block 22 and the outer side of the front and rear door lock bodies, and a clamping groove 23 for clamping the door panel is provided between the front door lock body 1 and the rear door lock body 2. The limiting block 22 is provided with an abutting block 24 that protrudes toward the door panel installation direction; The distance between the inner end face of the limiting block 22 and the inner end face of the abutment block 24 is greater than the thickness of the rigid linkage piece 18, so as to prevent the door panel from interfering with the rigid linkage piece 18. The first mounting block 20, the second mounting block 21, the limiting block 22, the abutting block 24 and the door panel together form an enclosed area with openings at both the top and bottom, and the linkage 8 is located within the enclosed area; The door panel is made of glass.

[0040] The front door lock body 1 is located on the outside of the door panel, and the rear door lock body 2 is located on the inside of the door panel.

[0041] The first connecting block 10, the second connecting block 11, and the rigid linkage plate 18 together constitute a U-shaped linkage component 8; During the movement of the U-shaped linkage 8, the two ends of the linkage 8 are relatively stationary, and its first connecting block 10 and second connecting block 11 move upward or downward synchronously. The U-shaped linkage consists of 8 rigid steel sheets (non-soft materials) with a thickness of 1mm to 3mm. The first connecting block 10 has protrusions 10.1 on its side to reduce wear.

[0042] The first connecting block 10 and the second connecting block 11 move synchronously through the rigid linkage plate 18, ensuring the integrity and stability of the first linkage component 8 during movement and avoiding transmission disorder caused by asynchronous movement of the two connecting blocks. The first mounting block 20 and the second mounting block 21 of the bracket 19 are respectively fixed inside the front door lock body 1 and the rear door lock body 2, providing a stable mounting base for the linkage assembly 3, enhancing the structural rigidity of the entire linkage device, and reducing shaking or deformation of the door lock during use. The limiting block 22 limits the rigid linkage plate 18 between itself and the outer side of the front and rear door lock bodies, further restricting the range of motion of the rigid linkage plate 18 and ensuring the accuracy of the movement of the first linkage component 8. The bracket 19 and the first linkage component 8 protrude from one end on the outer side of the door lock body, making reasonable use of the external space of the lock body and avoiding excessive occupation of the internal space, making the lock body structure more compact. The abutting block 24 abuts against the side of the door panel, effectively preventing interference between the door panel and the rigid linkage piece 18, avoiding obstruction of the first linkage piece 8 during its up and down movement, and preventing the first linkage piece 8 from scraping the door panel during its up and down movement, thus avoiding abnormal noise and damage to the side of the door panel.

[0043] In this technical solution, the second connecting block 11 is slidably mounted on the second mounting block 21, and the second mounting block 21 is provided with two first limiting pins that are spaced apart vertically on the first limiting strip groove 16 of the second connecting block 11.

[0044] The first connecting block 10 is slidably mounted on the first mounting block 20. The first mounting block 20 is provided with a second limiting pin corresponding to the first limiting groove 16 of the first connecting block 10. The height of the second limiting pin is located between the two first limiting pins.

[0045] The second linkage 9 is slidably mounted on the second mounting block 21. The second mounting block 21 has two third limiting pins arranged vertically at intervals in the second limiting groove 17 corresponding to the second linkage 9. The two first limiting pins and the two third limiting pins are at the same height.

[0046] The second mounting block 21 of the bracket 19 is provided with a horizontally telescopic locking tongue assembly 4; The second mounting block 21 is provided with a swing block 25. The first end of the swing block 25 acts on the locking tongue assembly 4, the second end of the swing block 25 is rotatably connected to the second mounting block 21, and the second end of the swing block 25 is connected to the rear operation assembly 6 in a transmission manner. The rear operation component 6 drives the swing block 25 to act on the latch assembly 4, so that the latch assembly 4 can perform a retracting action. The front operating component 5 is linked to the rear operating component 6 through the linkage assembly 3 to drive the locking tongue component 4 to extend and retract.

[0047] The swing block 25, mounted on the second mounting block 21 of the bracket 19, cleverly converts the driving force of the rear operating component 6 into the extension and retraction of the lock tongue assembly 4 through a transmission connection between its first end and the second end. This transmission structure is simple and efficient. The rear operating component 6 can directly drive the swing block 25 to control the lock tongue assembly 4, ensuring the directness and reliability of the rear lock body operation. The front operating component 5 is linked to the rear operating component 6 through the linkage assembly 3, allowing the user to indirectly drive the extension and retraction of the lock tongue assembly 4 through the linkage structure when operating the front operating component 5 from outside the door. This achieves integrated control of front and rear operations, improving the convenience of using the door lock. The rotating connection of the swing block 25 makes power transmission more flexible, reduces jamming during transmission, improves the smoothness of the extension and retraction of the lock tongue assembly 4, and enhances the user's operating experience.

[0048] The latch assembly 4 is provided with a third limiting groove 26 for limiting the lateral extension and retraction displacement of the latch assembly 4. The third limiting groove 26 is laterally arranged on the latch assembly 4.

[0049] The third limiting groove 26, horizontally positioned on the latch assembly 4, precisely limits the lateral extension and retraction of the latch assembly 4. This prevents the latch from extending too far and colliding with the door frame, or from retracting too much and failing to eject properly, thus protecting both the latch assembly 4 and the door frame. The precise travel limitation ensures that the latch assembly 4 accurately engages with the door frame keyhole when locked, guaranteeing the locking effect and improving security. When unlocked, it fully retracts, avoiding interference with the door frame and ensuring smooth door opening and closing. Furthermore, the third limiting groove 26 has a simple structure, eliminating the need for complex limiting mechanisms, saving internal space and reducing manufacturing costs. Simultaneously, the limiting effect makes the movement of the latch assembly 4 smoother, reducing wobbling during movement, extending its lifespan, and providing users with stable feedback and improved operating feel.

[0050] The latch assembly 4 is movably located inside the rear door lock body 2.

[0051] The rear door lock body 2 has a telescopic clearance opening 27 at one end corresponding to the bolt assembly 4.

[0052] The telescopic clearance opening 27 provided at one end of the rear door lock body 2 corresponding to the bolt assembly 4 provides sufficient space for the lateral telescopic movement of the bolt assembly 4, ensuring that the bolt assembly 4 is not obstructed by the rear door lock body 2 during telescopic movement.

[0053] The latch assembly 4 is provided with a slot 28. The first end of the swing block 25 extends into the slot 28 of the latch assembly 4. During the swinging process, the swing block 25 acts on the inner side of the slot 28 to drive the latch assembly 4 to move. The rear operation component 6 is provided with a first gear 30 that is connected to the swing block 25 for transmission.

[0054] The engagement between the slot 28 on the latch assembly 4 and the first end of the swing block 25 allows the swing block 25 to stably act on the inner side of the slot 28 during swinging, thereby driving the latch assembly 4 to move. This structure ensures effective force transmission between the swing block 25 and the latch assembly 4, avoids slippage during transmission, and improves transmission reliability. The slot 28 provides good limiting for the first end of the swing block 25, preventing the swing block 25 from disengaging from the latch assembly 4 during movement and ensuring continuous transmission. The first gear 30 on the rear operating assembly 6 is connected to the swing block 25 via gear transmission, further optimizing power transmission efficiency. This allows the driving force of the rear operating assembly 6 to be transmitted to the swing block 25 more smoothly, reducing fluctuations during power transmission and making the extension and retraction of the latch assembly 4 more stable.

[0055] The front operation component 5 or the rear operation component 6 is a voice recognition, fingerprint recognition, face recognition, or manual operation component.

[0056] The front operation component 5 or rear operation component 6 employs multiple methods such as voice recognition, fingerprint recognition, facial recognition, or manual operation, greatly enhancing the applicability and intelligence of the door lock. Compared to the traditional single manual operation method, the diverse operation components can meet the usage habits and scenario needs of different users. For example, fingerprint and facial recognition components enable quick contactless unlocking, improving convenience and security, especially suitable for use in places with high hygiene requirements; voice recognition components provide convenience for visually impaired or hand-impaired users; and manual operation components can serve as a backup operation method, ensuring the door lock can still be used normally when the electronic recognition component malfunctions or there is a power outage, improving the reliability of the door lock. The compatibility of multiple operation methods allows this door lock to be widely used in various scenarios such as homes, offices, and businesses, enhancing the product's market competitiveness.

[0057] The front door lock body 1 is also equipped with a touch screen, a fingerprint recognition module and a camera module, all of which are electrically connected to the control circuit board; The touch screen is equipped with touch numeric keys. When the correct number is entered on the touch screen, the control circuit board controls the motor to drive the corresponding gear of the gear transmission group 31 to rotate, and drives the linkage assembly 3 to move up and down, so as to realize the linkage of the operation component 6 after triggering and drive the lock tongue assembly 4 to move. The fingerprint recognition module collects fingerprints, and the control circuit board controls the motor to drive the corresponding gear of the gear transmission group 31 to rotate, which in turn drives the linkage assembly 3 to move up and down, thereby realizing the linkage of the operation component 6 after triggering and driving the lock tongue assembly 4 to move. The camera module captures facial images, and the control circuit board controls the corresponding gears of the motor drive gear transmission group 31 to rotate, which in turn drives the linkage assembly 3 to move up and down, thereby realizing the linkage of the operation component 6 after triggering and driving the lock tongue assembly 4 to move.

[0058] Alternatively, the key can be inserted to drive the linkage assembly 3 to move up and down, or the linkage assembly 3 can be driven to move up and down by the knob 12.

[0059] The above is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
