Description

Technical Field

[0001] This utility model belongs to the field of lock technology, specifically relating to an eco-lock quick-install inner handle assembly. Background Technology

[0002] In the field of door lock technology, the connection structure of various door lock components plays a crucial role in its ease of installation, stability, and overall performance. Currently, related technologies, such as the patent document with publication number [CN222745842U], disclose a door lock structure in which the inner handle seat 11 and the mounting cover 15 of the inner handle assembly are connected by screws. In this prior art solution, the inner handle seat 11 and the mounting cover 15 are fixed together by several screws to achieve their connection and positioning, thereby ensuring the realization of the door lock's related functions. However, this traditional screw connection method has revealed many drawbacks in practical applications. During installation, tools such as screwdrivers are required, making the process cumbersome, time-consuming, and labor-intensive, significantly reducing installation efficiency. Moreover, screws are prone to loosening and stripping when frequently disassembled or subjected to external forces such as vibration, leading to unstable connections between the inner handle seat 11 and the mounting cover 15, affecting the normal use of the door lock. Furthermore, the loss of screws increases maintenance costs and difficulty. As users' demands for door lock experience continue to increase, improving the connection structure of the inner handle assembly and addressing the shortcomings of traditional screw connections has become an urgent issue to be resolved in this field. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art and provide an eco-lock quick-install inner handle assembly, which connects the inner handle seat and the mounting cover together through a rotating snap-fit ​​structure, without the need for screws for fixing.

[0004] The technical solution of this utility model is as follows: an eco-friendly lock quick-install inner handle assembly, including a mounting cover for installation on the inside of a door panel and an inner handle seat for installation of the inner handle. The mounting cover has a through hole for a through screw to pass through. The inner handle seat and the mounting cover are connected by a rotating snap-fit ​​structure. The rotating snap-fit ​​structure includes a snap block and a screw groove respectively provided on the inner handle seat and the mounting cover. The screw groove has an axially arranged inlet / outlet groove and a circumferentially arranged slot. One end of the inlet / outlet groove is open and the other end communicates with the slot. The snap block can enter the inlet / outlet groove axially and slide into the slot through the circumferential rotation of the inner handle seat to form an axial fixation.

[0005] By adopting the above technical solution, the design of this rotating snap-fit ​​structure eliminates the need for screws in the connection between the inner handle base and the mounting cover, thus avoiding the cumbersome installation process, time and labor consumption, and unstable connection problems associated with screw connections. During installation, simply align the snap-fit ​​block with the opening end of the slot, push it in axially, and then rotate the inner handle base to allow the snap-fit ​​block to slide smoothly into the slot, achieving a quick and stable connection. Compared to traditional screw connections, the eco-lock quick-install inner handle assembly provided by this invention simplifies the installation process and improves installation efficiency.

[0006] A further feature of this invention is that the inlet and outlet slots are V-shaped.

[0007] With the above-mentioned further design, the "V" shaped structure not only facilitates the smooth insertion of the card block, but also effectively guides the path of the card block during rotation, ensuring that the card block can slide accurately into the card slot.

[0008] A further feature of this invention is that multiple locking blocks are provided in the circumferential direction, and multiple rotating grooves are also provided, each corresponding to one of the locking blocks.

[0009] The further design described above, with multiple locking blocks corresponding to multiple screw-in slots, greatly enhances the connection stability between the inner handle base and the mounting cover. This multi-point locking method not only distributes the connection force, making the connection more secure, but also ensures that even if one locking block wears out due to long-term use or external force, the other locking blocks can still maintain an effective connection, thereby extending the service life of the entire assembly.

[0010] A further feature of this invention is as follows: the inner handle seat is sleeved outside the mounting cover, the inner wall of the inner handle seat is provided with a locking block, and the outer periphery of the mounting cover has a screw-in groove, wherein the outer end of the groove is open and the inner end communicates with the locking groove; or the outer periphery of the mounting cover is provided with a locking block, and the inner wall of the inner handle seat has a screw-in groove, wherein the inner end of the groove is open and the outer end communicates with the locking groove.

[0011] With the further modifications described above, the engagement method between the inner handle seat and the mounting cover becomes more flexible and adaptable to different installation needs. When the inner handle seat is fitted over the mounting cover, the locking block can be smoothly inserted from the outer end of the slot and slide into the slot along a preset path during rotation, achieving a secure engagement. Conversely, when the mounting cover has a locking block on its outer circumference, the screw groove on the inner wall of the inner handle seat can accommodate the locking block, allowing it to smoothly enter through the inner opening of the slot, and the slot and locking block are locked together.

[0012] A further feature of this invention is that the inner handle is provided with a locking assembly for driving the transmission core to rotate. The locking assembly includes a sliding knob and a locking core rotatably disposed in the inner handle. The locking core is linked with the transmission core. The outer circumference of the locking core has a spiral groove. The inner side of the knob has a positioning pin located in the spiral groove. By cooperating with the spiral groove, the linear sliding of the knob can be converted into the rotation of the locking core. The knob has an unlocking position and a locking position.

[0013] With the above-described further design, in the unlocked position, the positioning pin is located at a specific position in the spiral groove. At this time, the deadbolt cylinder will not rotate due to the sliding of the lever, and the lock remains in the normal open state. When it is necessary to deadbolt the lock, the user only needs to push the lever to the deadbolt position. The positioning pin will then move within the spiral groove and drive the deadbolt cylinder to rotate accordingly, thereby achieving the deadbolt action of the bolt through the transmission core.

[0014] A further feature of this invention is that the toggle switch adopts a gear positioning structure to achieve positioning of the toggle switch in the unlocking or locking gear position.

[0015] With the above-mentioned further settings, a gear positioning structure design is adopted to ensure that the toggle switch can be accurately positioned when unlocking or locking the gear, thus avoiding misoperation.

[0016] A further feature of this invention is that the gear positioning structure includes an elastic component and a positioning component respectively disposed on the toggle switch and the inner handle. The elastic component has a positioning protrusion, and the positioning component has a first positioning groove and a second positioning groove. The two positioning grooves correspond to the unlocking position and the locking position respectively, and are distributed at intervals along the sliding direction of the toggle switch. The groove opening of each positioning groove faces the positioning protrusion. When the toggle switch slides to the unlocking position or the locking position, the positioning protrusion engages with the corresponding positioning groove to position the toggle switch.

[0017] With the further design described above, when the toggle is in the unlocked position, the positioning protrusion engages with the first positioning groove, securing the toggle firmly in the unlocked position. Users cannot easily change its position by touching it, ensuring the stability of the lock during normal use. Similarly, when the toggle slides to the deadbolt position, the positioning protrusion engages with the second positioning groove, positioning the toggle in the deadbolt position. This design greatly enhances the lock's security performance, effectively preventing accidental opening or locking due to misoperation. Furthermore, the elastic component design allows the positioning protrusion to easily disengage from the positioning groove, facilitating user switching between different positions.

[0018] A further feature of this invention is as follows: the positioning component is connected inside the inner handle and is cylindrically sleeved outside the deadbolt cylinder. The positioning component has an opening groove at the position of the spiral groove corresponding to the deadbolt cylinder. The opening groove extends along the sliding direction of the lever. The positioning pin on the lever passes through the opening groove and is inserted into the spiral groove. The positioning component has corresponding positioning grooves on both sides of the opening groove. The elastic component is disposed on the inner side of the lever, and its positioning protrusion forms a locking engagement with the corresponding positioning grooves on both sides.

[0019] With the above-mentioned further configuration, the positioning component has an opening groove at the position of the spiral groove corresponding to the anti-lock cylinder, so that the positioning pin on the lever can pass through the opening groove and be inserted into the spiral groove; and a first positioning groove and a second positioning groove are provided on both sides of the opening groove to ensure the smoothness and accuracy of the lever during the sliding process.

[0020] A further feature of this invention is as follows: the positioning component and the inner handle are circumferentially positioned by the cooperation of the insert and the slot, and are axially confined within the inner handle; the elastic component is installed in the V-shaped groove on the inner side of the lever and sleeved outside the positioning pin; a lever is provided on the outer side of the lever, the lever extends out of the movable window on the inner handle; the positioning pin and the lever are respectively located in the middle of both sides of the lever, and a status indication area is formed on each end of the lever on the outer side of the lever.

[0021] With the aforementioned further design, the positioning component not only achieves circumferential positioning with the inner handle through the insert and slot, but is also axially confined within the inner handle, enhancing the stability and reliability of the structure. The elastic component is cleverly installed within the V-shaped groove on the inner side of the lever and fitted over the positioning pin. This design ensures the secure installation of the elastic component while effectively utilizing its elasticity. The lever located on the outer side of the lever facilitates user operation; the positioning pin and lever are located in the middle of both sides of the lever, a layout that makes the lever more evenly stressed and improves its service life. Furthermore, a status indicator area is formed at each end of the lever on the outer side of the lever, allowing users to determine the current status of the lock, such as whether it is deadbolted, by observing different indicator areas, improving ease of use and intuitiveness.

[0022] A further feature of this invention is that the elastic component is a spring sheet structure, with a "V"-shaped bulge in the middle of the spring sheet to form the positioning protrusion, and the corresponding positioning groove has a "V"-shaped structure.

[0023] By further modifying the aforementioned design, the elastic component of the spring-loaded structure is not only simple in structure but also easy to manufacture and install, reducing production costs. Its "V"-shaped locating protrusions cooperate with corresponding "V"-shaped locating grooves to achieve precise axial positioning, preventing loosening or displacement during use. This design not only improves the stability and reliability of the lock but also makes operation smoother, enhancing the user experience. Furthermore, the elastic component of the spring-loaded structure has excellent elasticity and resilience, maintaining stable performance over long-term use and extending the lock's lifespan.

Furthermore, the inner handle seat 2 and the mounting cover 1 can be connected by screws to further enhance the connection stability between them.

[0037] Specifically, the inner handle 3 is provided with a locking assembly 4 for driving the transmission core to rotate. The locking assembly 4 includes a slidingly disposed lever 41 and a locking core 42 rotatably disposed in the inner handle 3. The locking core 42 is linked with the transmission core (using screw connection or plug-in engagement, etc.). The outer periphery of the locking core 42 has a spiral groove 421. The inner side of the lever 41 has a positioning pin 411 located in the spiral groove 421. Through the engagement of the positioning pin 411 and the spiral groove 421, the linear sliding of the lever 41 can be converted into the rotation of the locking core 42. The lever 41 has an unlocking position and a locking position. The lever 41 adopts a position positioning structure to achieve positioning of the lever 41 in the unlocking position or the locking position. The gear positioning structure includes an elastic component 43 and a positioning component 44 respectively disposed on the toggle knob 41 and the inner handle 3. Specifically, the elastic component 43 is disposed on the toggle knob 41 and the positioning component 44 is disposed on the inner handle 3, or the positioning component 44 is disposed on the toggle knob 41 and the elastic component 43 is disposed on the inner handle 3. The elastic component 43 has a positioning protrusion 431, and the positioning component 44 has a first positioning groove 441 and a second positioning groove 442. The two positioning grooves correspond to the unlock position and the deadbolt position respectively, and are distributed at intervals along the sliding direction of the toggle knob 41. The groove opening of each positioning groove faces the positioning protrusion 431. When the toggle knob 41 slides to the unlock position or the deadbolt position, the positioning protrusion 431 engages with the corresponding positioning groove to position the toggle knob 41. The elastic component 43 is a spring sheet structure, and the middle part of the spring sheet has a "V" shaped bulge to form the positioning protrusion 431. The corresponding positioning grooves 441 and 442 have a "V" shaped structure. The positioning protrusion 431 can also be circular or have other structures. The positioning component 44 is connected inside the inner handle 3 and is cylindrically sleeved outside the deadbolt cylinder 42. The positioning component 44 and the inner handle 3 can be fixed or integrally connected. The positioning component 44 has an opening groove 443 at the position corresponding to the spiral groove 421 of the deadbolt cylinder 42. The opening groove 443 extends along the sliding direction of the lever 41. The positioning pin 411 on the lever 41 passes through the opening groove 443 and is inserted into the spiral groove 421. The positioning component 44 is provided with corresponding positioning grooves 441 and 442 on both sides of the opening groove 443. The elastic component 43 is provided on the inner side of the lever 41, and its positioning protrusion 431 forms a locking engagement with the corresponding positioning grooves 441 and 442 on both sides.The positioning component 44 and the inner handle 3 are circumferentially positioned by the cooperation of the insert block 51 and the slot 52, and are axially limited in the inner handle 3 (such as by pressing the positioning component 44 into the inner cavity of the inner handle by the pressure plate 45 to achieve axial positioning). The elastic component 43 is installed in the V-shaped groove 412 inside the toggle 41 and sleeved outside the positioning pin 411. The elastic component 43 has a hole 432 in the middle for the positioning pin 411 to pass through. The toggle 41 is provided with a lever 413 on the outside of the toggle 41. The lever 413 extends out of the movable window 31 on the inner handle 3. The positioning pin 411 and the lever 413 are respectively located in the middle of both sides of the toggle 41. A status indicator area 414 is formed at each end of the lever 413 on the outside of the toggle 41. The two status indicator areas can indicate the current status by different colors.

[0038] Of course, the toggle switch can also use a ball-positioning structure to achieve gear positioning. Specifically, a positioning hole is provided on the toggle switch, and a compression spring and a ball are installed in the positioning hole. When the toggle switch slides to the unlock position or the deadbolt position, the ball is engaged in the corresponding positioning groove under the action of the spring force, thereby achieving stable locking of the toggle switch in the two positions; when it is necessary to switch gears, an external force is applied to push the toggle switch, causing the ball to overcome the spring force and exit the positioning groove, completing the gear switching. Alternatively, an elastic positioning structure can be used to achieve gear locking.

[0039] like Figure 10 , 11 An eco-lock is shown, comprising the aforementioned inner handle assembly A, and an outer handle assembly B, coupling C, and transmission core D with the same structure as the prior art. The outer handle assembly B includes an outer handle base B1, an outer handle B2, and a key lock cylinder assembly B3. Both the inner handle assembly A and the outer handle assembly B have coupling seats. The two ends of the coupling C are respectively inserted into the two coupling seats, enabling the inner and outer handles to move together. The coupling seats are fixed or integrally set with the corresponding handles. A transmission core that can rotate relative to the inner handle is inserted through the coupling. The two ends of the transmission core are respectively connected to a deadbolt assembly and a key lock cylinder assembly. During installation, the through screw E passes through the mounting cover placed inside the door and is then connected and fixed to the outer handle base placed outside the door. The inner handle base is then installed outside the mounting cover.
