Abstract

This invention belongs to the field of door and window technology, and provides a sliding handle lock, including a handle and a lock housing assembly. The lock housing assembly includes a transmission component, a base, a bolt, a drive component, and a linkage. The drive component is rotatably mounted on the base and driven by a lock cylinder on one side. When the drive component rotates, it can drive the transmission component to move to control the unlocking or locking of the lock. The handle is fixedly connected to the transmission component, and the lock cylinder on the other side is mounted on the handle. The linkage cooperates with both the lock cylinder on the handle and the drive component to achieve a relative linear displacement between the lock cylinder and the drive component when the handle moves, while maintaining a synchronous rotational linkage. This invention allows the lock to be unlocked or locked by pushing an external handle, eliminating the need for an external component similar to a lever, making the lock portion exposed outside the profile simpler, and facilitating the adaptation of the handle to narrow profiles.

Description

Technical Field

[0001] This invention belongs to the field of door and window technology, and specifically relates to a sliding handle lock. Background Technology

[0002] Sliding door handle locks, also known as sliding door locks, generally combine a handle and a lock into a single hardware component. The handle is often designed in a D-shape. During use, in addition to unlocking or locking the lock by rotating the hook with a key, external levers or blocks can be used to manipulate the hook for quick unlocking or locking. Regardless, existing sliding door handle locks typically include an external control component, such as the manual operating component in patent application CN111255293A, the control handle in patent application CN101892780A, and the pin linkage element in patent application CN101790616A.

[0003] However, in recent years, sliding doors and windows have been continuously innovated, gradually moving towards narrower visible profiles, more transparent overall designs, and simpler shapes. The traditional bulky handle lock is no longer compatible with the design concepts of the new era. Moreover, too many external components hinder the promotion of narrow profiles, making it difficult to update sliding door and window products. Therefore, it is necessary to propose a new lock structure to simplify the external components of the lock to the greatest extent possible. Summary of the Invention

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this invention is to provide a sliding handle lock, which can be controlled to unlock or lock by pushing an external handle, eliminating the need for an external component similar to a lever, making the lock part exposed outside the profile simpler, and facilitating the adaptation of the handle to narrow profiles.

[0005] The technical solution adopted by this invention to solve its technical problem is: A sliding handle lock includes a handle and a lock housing assembly; The lock housing assembly includes a transmission component, a base, a latch, a drive component, and a linkage; the base is fixed to the profile, the latch is rotatably connected to the base, the transmission component is movable relative to the base and drives the latch to rotate when it moves, controlling the unlocking or locking of the lock; the drive component is rotatably mounted on the base and driven by the lock cylinder on one side, and when the drive component rotates, it also drives the transmission component to move to control the unlocking or locking of the lock; The handle is fixedly connected to the transmission component, and the handle moves synchronously with the transmission component. The lock cylinder on the other side is located on the handle. The linkage works in conjunction with the lock cylinder on the handle and the drive component to achieve a relative linear displacement between the lock cylinder and the drive component when the handle moves, while maintaining a synchronous rotational linkage.

[0006] In a preferred embodiment of the present invention, the linkage includes a first rotating member, a second rotating member, and a linkage member; the first rotating member moves linearly with the transmission component and can rotate about its own axis; the second rotating member and the driving component are configured to rotate synchronously. The linkage is located between the first rotating member and the second rotating member. Limiting structures are provided between the first rotating member and the linkage, and between the second rotating member and the linkage, to enable all three to rotate simultaneously. The linkage can move relative to the first rotating member along a first direction, and simultaneously move relative to the second rotating member along a second direction. The first direction and the second direction are perpendicular to each other. Furthermore, when the first rotating member is forced to move linearly, the first rotating member, the linkage, and the second rotating member rotate simultaneously. Under the connection of the linkage, the first rotating member and the second rotating member undergo linear relative displacement, at which time the lock switches between the unlocked state and the locked state.

[0007] Preferably, the lock housing assembly has a locking function; when the first rotating member is forced to rotate only, the linkage member and the second rotating member rotate simultaneously, at which time the lock switches between a locked state and a locked state.

[0008] Preferably, each of the limiting structures includes two limiting parts that cooperate in a concave-convex interlocking manner. The two limiting parts extend in a straight line and can slide relative to each other to realize the relative movement between the linkage member and the first rotating member and between the linkage member and the second rotating member.

[0009] Preferably, the first rotating member includes a cylinder and a base plate, the base plate being located on the side of the cylinder closer to the linkage member, the cylinder extending away from the linkage member, and the cylinder having a mating cavity for engaging with the lock cylinder on the handle; the limiting structure is disposed between the base plate and the linkage member; The transmission component has a through hole; the cylinder passes through the through hole and is rotatable.

[0010] In a preferred embodiment of the present invention, the driving member is provided with a driving boss, which is located radially outside the rotation axis of the driving member; the transmission component is provided with a driving slot corresponding to the driving boss, and when the driving member rotates, the transmission component is pushed to slide by the action of the driving boss on both sides of the driving slot.

[0011] Preferably, the lock housing assembly has a locking function. When the first rotating member is forced to rotate only on its own axis, the linkage member and the second rotating member rotate simultaneously, at which time the lock switches between a locked state and a locked state. The transmission component has a locking boss that protrudes towards the driving component. The driving component has a relief groove on the side facing the locking boss, and the relief groove has an opening. When the driving component rotates to the locked position, the locking boss moves through the opening to the outside of the relief groove and is pressed against the outer circumferential wall of the driving component, so as to prevent the locking boss from moving in the unlocking direction and thus locking the transmission component and the bolt. The driving component presses against the outer circumferential wall of the locking boss to form a locking surface.

[0012] In a preferred embodiment of the present invention, a connecting post is provided on the side of the second rotating member away from the linkage member; the driving member is provided with a connecting cavity adapted to the connecting post; the connecting post is inserted into the connecting cavity; and a limiting feature is provided between the connecting post and the connecting cavity to restrict the relative circumferential rotation of the two.

[0013] In a preferred embodiment of the present invention, the base includes a main body and two sliding support portions respectively connected to both ends of the main body; the transmission component and the two sliding support portions are provided with sliders at corresponding positions, and the sliders are adapted to the sliding support portions to form a sliding guide and limit for the transmission component.

[0014] In a preferred embodiment of the present invention, the handle is provided with a receiving cavity, and the lock housing assembly is disposed in the receiving cavity; the two ends of the handle in the length direction are connected and fixed to the two ends of the transmission component in the length direction.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention innovates upon existing sliding door handle locks by fixing the handle, which is externally mounted on the profile, to the transmission components. This allows the lock to be unlocked or locked simply by pushing the handle, eliminating the need for external components such as levers and levers in traditional handle locks. The handle itself becomes the operating part for controlling the movement of the transmission components, greatly simplifying the external structure.

[0016] Since the lock handle also functions as a means of controlling the movement of the transmission components, and there are no traditional external components such as levers or levers, the shape of the handle can be more diverse. In particular, it can be appropriately adjusted according to the width of the profile to meet the needs of extremely narrow bezels. Attached Figure Description

Detailed Implementation

[0033] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of the present invention; the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0035] See Figures 1-14 This embodiment discloses a sliding handle lock, including a handle 1 and a lock housing assembly 3.

[0036] The lock housing assembly 3 in this embodiment includes a transmission component 4, a base 5, a latch 6, a drive component 7, and a linkage 9. The base 5 is fixed to the profile. The latch 6 is rotatably connected to the base 5. The transmission component 4 can move relative to the base 5, and when it moves, it drives the latch 6 to rotate, controlling the unlocking or locking of the lock. One or two latches 6 can be used. To improve the locking effect, two latches 6 are generally used to cooperate with the lock seat on the door or window frame. The form of the latch 6 can be flexibly adjusted. In this embodiment, the latch 6 adopts a hook-shaped structure, but it is not limited to this. The drive component 7 is rotatably mounted on the base 5 and is driven by the lock cylinder on one side. When the drive component 7 rotates, it also drives the transmission component 4 to move, controlling the unlocking or locking of the lock. Generally, the drive component 7 cooperates with the outdoor lock cylinder, that is, the outdoor lock cylinder controls the rotation of the drive component 7, realizing outdoor control of the lock.

[0037] Traditional handle locks typically have a lock cylinder on the other side of the handle 1, usually an indoor lock cylinder 2. This indoor lock cylinder 2 also controls the rotation of the drive component 7 to unlock or lock the lock. In addition, a lever-like component connects to the transmission component 4; moving the lever moves the transmission component 4, thus controlling the lock. The sliding handle lock of this embodiment innovatively improves upon this design.

[0038] In this embodiment, the handle 1 is fixedly connected to the transmission component 4, and the handle 1 and the transmission component 4 move synchronously. The indoor lock cylinder 2 is still located on the handle 1, but the indoor lock cylinder 2 on the handle 1 is now matched with the linkage 9. The linkage 9 on the lock housing assembly 3 matches both the indoor lock cylinder 2 on the handle 1 and the drive component 7, so that when the handle 1 moves, the lock cylinder and the drive component 7 have relative linear displacement and always maintain a synchronous rotational linkage relationship.

[0039] Furthermore, the linkage 9 in this embodiment includes a first rotating member 901, a second rotating member 903, and a linkage member 902. The first rotating member 901 moves linearly with the transmission component 4 and can rotate around its own axis. The second rotating member 903 is coaxial with the driving component 7 and is configured to rotate synchronously. The linkage member 902 is located between the first rotating member 901 and the second rotating member 903. Limiting structures are provided between the first rotating member 901 and the linkage member 902, and between the second rotating member 903 and the linkage member 902, to enable all three to rotate simultaneously. When the first rotating member 901 is forced to move linearly, the first rotating member 901, the linkage member 902, and the second rotating member 903 rotate simultaneously. Under the connection of the linkage member 902, the first rotating member 901 and the second rotating member 903 undergo linear relative displacement, at which time the lock switches between an unlocked state and a locked state. In this embodiment, the lock housing assembly 3 also has a locking function. Therefore, when the first rotating member 901 is prompted to rotate only, the linkage member 902 and the second rotating member 903 rotate simultaneously, and the lock switches between the locked state and the locked state.

[0040] Furthermore, each limiting structure includes two limiting portions that engage with each other using a concave-convex interlocking method. The two limiting portions extend in a straight line and can slide relative to each other to achieve relative movement between the linkage member 902 and the first rotating member 901, and between the linkage member 902 and the second rotating member 903. For example, the two limiting portions are a protrusion 11 and a groove 10, respectively. The groove 10 has openings at both ends, and the protrusion 11 can move relative to the groove 10. Specifically, in this embodiment, the limiting portion on the side of the first rotating member 901 facing the linkage member 902 is the groove 10, and the limiting portion on the side of the linkage member 902 facing the first rotating member 901 is the protrusion 11. Similarly, the limiting portion on the side of the second rotating member 903 facing the linkage member 902 is the groove 10, and the limiting portion on the side of the linkage member 902 facing the second rotating member 903 is the protrusion 11. Of course, the positions of the protrusion 11 and the groove 10 can be flexibly adjusted. For example, the protrusion 11 can be set on the first rotating part 901, and the groove 10 can be set on the linkage part 902. Through the cooperation of the two, synchronous rotation and relative movement can also be achieved. Similarly, other adjustment methods can be flexibly selected according to the actual situation.

[0041] The two limiting parts, which engage in a concave-convex interlocking manner, enable synchronous rotation between the linkage 902 and the first rotating member 901, as well as between the linkage 902 and the second rotating member 903. That is, when either the first rotating member 901 or the second rotating member 903 is rotated, it drives the other two to rotate synchronously, thus facilitating the synchronous rotation of the lock cylinders on both the indoor and outdoor sides. Furthermore, the two limiting parts can slide relative to each other, allowing the first rotating member 901 to move relative to the linkage 902 while rotating, and the linkage 902 to move relative to the second rotating member 903 simultaneously. In other words, the linkage 902 acts as a link, facilitating the relative displacement of the first rotating member 901 and the second rotating member 903, i.e., the misalignment of their rotation axes. The ultimate goal is to enable the first rotating component 901 to move with the transmission component 4, which is fixedly connected to the handle 1. Thus, the control of the lock hook can be achieved by pushing the handle 1 to move the transmission component 4. At the same time, the first rotating component 901 and the second rotating component 903 also achieve the misalignment of their rotation axes, but this does not affect the rotation of the first rotating component 901 and the second rotating component 903. This allows the indoor and outdoor lock cylinders to continue to control the unlocking, locking, and closing of the lock, because the first rotating component 901 and the driving component 7 can be linked with the indoor and outdoor lock cylinders respectively, and the second rotating component 903 is configured to rotate synchronously with the driving component 7.

[0042] The extension direction of the limiting structure between the linkage 902 and the first rotating member 901 is the first direction, and the extension direction of the limiting structure between the linkage 902 and the second rotating member 903 is the second direction. The first and second directions are perpendicular to each other. This allows the linkage 902 to move relative to the first rotating member 901 along the first direction, and simultaneously, the linkage 902 can move relative to the second rotating member 903 along the second direction. Since the first and second directions are perpendicular to each other, the linkage 902 has two degrees of freedom of movement on a Cartesian coordinate axis.

[0043] Furthermore, in this embodiment, the thickness of the two limiting portions of the limiting structure is smaller than its width. For example... Figure 3 As shown, the limiting structure between the first rotating member 901 and the linkage member 902 is explained, and the limiting structure between the second rotating member 903 and the linkage member 902 is similar. The groove 10 on the first rotating member 901 and the protrusion 11 on the linkage member 902 are relatively wide but relatively thin, forming a thin structure with a certain width. The purpose of this design is that the thin structure can appropriately reduce the resistance when the two slide relative to each other, making the relative sliding during rotation smoother; at the same time, the certain width ensures the reliability of the protrusion 11 and the groove 10, making them less likely to detach and ensuring the function of synchronous rotation.

[0044] Furthermore, the linkage 902 is provided with a clearance portion 9021, which is located on the outer edge of the linkage 902 and is closer to the center of the linkage 902 than other parts of the outer edge of the linkage 902. For example... Figure 3 and Figure 9 As shown, the linkage 902 is roughly circular, but one of its outer edges is missing, forming a clearance portion 9021. This design allows for a smaller shape of the linkage 902. Since the linkage 902 deviates from the first rotating member 901 and the second rotating member 903 during movement, sufficient space needs to be provided in the base 5 and handle 1 to allow for the movement of the linkage 9. This embodiment, through the clearance portion 9021, minimizes the movement space of the linkage 902, allowing for a further reduction in lock size and creating favorable conditions for a minimalist lock design.

[0045] As another implementation, multiple linkage members 902 can be provided between the first rotating member 901 and the second rotating member 903, not just one. When multiple linkage members 902 are provided, they can also achieve simultaneous rotation and relative displacement by setting a limiting structure. However, providing multiple linkage members 902 will increase space requirements, which can be flexibly adjusted according to actual product needs.

[0046] The first rotating member 901 in this embodiment includes a cylinder 9011 and a base plate 9012. The base plate 9012 is located on the side of the cylinder 9011 closer to the linkage member 902. The cylinder 9011 extends away from the linkage member 902. The cylinder 9011 has a mating cavity 9013 for engaging with the lock cylinder on the handle 1. The inner wall of the mating cavity 9013 has a pusher boss 9014. A limiting structure is provided between the base plate 9012 and the linkage member 902. When the first rotating member 901 is rotated by the indoor lock cylinder 2, the key drives the indoor lock cylinder 2 to rotate. The indoor lock cylinder 2 has a pusher block corresponding to the pusher boss 9014. Therefore, when the indoor lock cylinder 2 rotates, the pusher block pushes the pusher boss 9014, thereby driving the first rotating member 901 to rotate.

[0047] To achieve synchronous movement between the transmission component 4 and the first rotating component 901, and to enable the first rotating component 901 to rotate, this embodiment includes a connecting plate 8 on the transmission component 4. Both the connecting plate 8 and the transmission component 4 have through holes 801. The cylinder 9011 on the first rotating component 901 passes through the through hole 801, enabling synchronous movement between the first rotating component 901 and the transmission component 4 of the lock. Furthermore, the cylinder 9011 can rotate while passing through the through hole 801. Alternatively, a through hole 801 that mates with the first rotating component 901 could be directly provided on the transmission component 4. However, this embodiment uses an additional connecting plate 8, making the assembly of these parts more convenient.

[0048] Regarding the cooperation between the second rotating member 903 and the driving member 7 in this embodiment, the following implementation method is adopted: A connecting post 9031 is provided on the side of the second rotating member 903 away from the linkage member 902; the driving member 7 is provided with a connecting cavity 701 adapted to the connecting post 9031; the connecting post 9031 is inserted into the connecting cavity 701; a limiting feature for restricting the relative circumferential rotation of the two is provided between the connecting post 9031 and the connecting cavity 701. This limiting feature includes at least one recess 12 and at least one protrusion 13, with the protrusion 13 embedded in the recess 12. The form and position of the recess 12 and protrusion 13 in the limiting feature of this embodiment can be flexibly set to primarily restrict the relative rotation of the second rotating member 903 and the driving member 7. Although this embodiment discloses one form, the scope of protection is not limited to this. For example, two recesses 12 are provided on the connecting post 9031 of the second rotating member 903, and correspondingly two protrusions 13 are provided on the connecting cavity 701 of the driving member 7. The recesses 12 and protrusions 13 cooperate with each other to achieve the rotation limiting effect. Meanwhile, two protrusions 13 are provided on the connecting post 9031 of the second rotating member 903, and two recesses 12 are provided on the end face of the connecting cavity 701 of the driving member 7, with the protrusions 13 and the recesses 12 cooperating with each other.

[0049] Regarding the cooperation between the driving component 7 and the transmission component 4, existing technology can be referenced. The main function is that the rotation of the driving component 7 drives the transmission component 4 to move, thereby causing the bolt 6 to rotate out or in, thus controlling the lock. Simultaneously, for locks with a locking function, a corresponding design is included to achieve a deadlock effect, in which the handle 1 cannot move and can only be released through the lock cylinder. However, the locking function of the lock is not essential.

[0050] In this embodiment, the cooperation between the driving component 7 and the transmission component 4 is achieved as follows: the driving component 7 is provided with a driving boss 702, which is located radially outward from the rotation axis of the driving component 7; the transmission component 4 is provided with a driving slot 401 corresponding to the driving boss 702. When the driving component 7 rotates, the driving boss 702 pushes the transmission component 4 to slide by acting on both sides of the driving slot 401. In this embodiment, the driving boss 702 is located on the end face of the disk 704 of the driving component 7 and protrudes 11 axially. This structure makes the cooperation between the transmission component 4 and the driving component 7 more compact and reliable, which is beneficial to reducing the overall width of the lock. Of course, the driving boss 702 can also be set on the circumferential surface of the disk 704 and protrudes 11 radially. This structure can also cooperate with the driving slot 401 on the transmission component 4 and form a linkage relationship, but this method will result in a larger overall structural width compared to the method used in this embodiment.

[0051] Furthermore, a chamfer 402 is provided on one side of the drive slot 401; the drive boss 702 moves away from the drive slot 401 after rotating past the side of the drive slot 401 with the chamfer 402, so that the drive member 7 can rotate to the locked position. When the transmission member 4 of this embodiment slides to the locked position, it will be restricted from continuing to slide, and the member will not be able to continue to slide in that direction. The restriction of the transmission member 4 can be achieved by limiting it with the base 5, or by other means, which is relatively easy to implement. Therefore, when the transmission member 4 slides to the locked position under the drive of the drive member 7, even if the drive member 7 continues to rotate, it cannot drive the transmission member 4 to continue to slide. However, continuing to rotate the drive member 7 will cause the drive boss 702 to rotate relative to the drive slot 401, thereby moving away from the drive slot 401. This is to achieve a locking effect, which will be explained below. In this embodiment, the chamfer 402 facilitates the rotation of the drive boss 702. Similarly, when the drive member 7 rotates in the opposite direction to move the transmission member 4 in the unlocking direction, it also facilitates the drive boss 702 entering the drive slot 401. Of course, a rounded corner can also be provided on one side of the drive slot 401.

[0052] The transmission component 4 is provided with a hollow groove 403, which is connected to the drive slot 401. When the drive component 7 rotates from the unlocked position to the locked position, the drive boss 702 rotates from the drive slot 401 into the hollow groove 403. The hollow groove 403 is provided with a baffle 404. When the drive component 7 rotates to the locked position, the drive boss 702 abuts against the baffle 404 to prevent the drive component 7 from continuing to rotate.

[0053] Meanwhile, to achieve the locking function, a locking boss 405 protruding 11 towards the driving member 7 is provided on the transmission component 4. The disk 704 of the driving member 7 is provided with a relief groove 703 on the side facing the locking boss 405. The relief groove 703 has an opening. When the driving member 7 rotates to the locking position, the locking boss 405 moves out of the relief groove 703 through the opening and is pressed against the outer circumferential wall of the driving member 7 to prevent the locking boss 405 from moving in the unlocking direction and thus lock the transmission component 4 and the locking tongue 6. The driving member 7 presses against the outer circumferential wall of the locking boss 405 to form a locking surface 705.

[0054] Furthermore, the inner wall of the clearance groove 703 includes a clearance section 7031 and a transition section 7032. Along the direction of the drive member 7's rotation from the unlocked position to the locked position, the clearance section 7031 and the transition section 7032 are connected sequentially, with the transition section 7032 gradually moving away from the rotation center of the disc 704 and eventually extending to the outer circumference of the disc 704. During the rotation of the drive member 7 from the unlocked position to the locked position, the drive member 7 drives the transmission component 4 to slide relative to the base 5, causing a change in the relative position between the locking boss 405 and the drive member 7. Specifically, when the drive member 7 rotates, the locking boss 405 sequentially passes through the clearance section 7031, the transition section 7032, and the opening, finally leaving the clearance groove 703 and corresponding to the outer circumference of the disc 704, forming a mutual limiting effect. In this state, the outer circumference of the disc 704 blocks the locking boss 405, preventing the transmission component 4 from moving in the unlocking direction and achieving a locking effect. This keeps the transmission component 4 and the locking tongue 6 in the locked position, which can also be called a deadlock state.

[0055] Furthermore, a limiting wall 7033 is provided at the end of the clearance groove 703 away from the opening. See also Figure 6 , Figures 7-9 The limiting wall 7033 can restrict the travel of the locking boss 405 and the rotation of the drive member 7, making it easier to stop the drive member 7 after it is rotated to the unlock position, thus serving a positioning function. Of course, the positioning and restriction of the drive member 7 rotating to the unlock position and the transmission component 4 moving to the unlock position can also be achieved in other ways or in combination with the aforementioned limiting wall 7033. For example, the rotation of the lock cylinder can be restricted, the travel of the transmission component 4 can be restricted, or other limiting features can be provided on the base 5 to restrict the rotation of the drive member 7, etc.

[0056] In addition, to improve positioning accuracy and the user's feel when controlling the lock with the lock cylinder, a positioning structure 15 can be provided on the base 5. This positioning structure 15 can accurately control the rotation angle of the drive component 7. For example, multiple positioning grooves can be set on the circumferential surface of the drive component 7, corresponding to the unlocking, locking, and closed positions. Corresponding positioning steel balls and springs can be set on the base 5. The positioning effect is achieved by the positioning cooperation between the positioning steel balls and the positioning grooves. The above positioning method can also be found in existing technology.

[0057] The base 5 of this embodiment has many functions, such as limiting and supporting the rotation of the locking tongue 6, installing the drive component 7, and installing the anti-misoperation push rod 16, all of which can be found in the prior art. Specifically, the base 5 of this embodiment includes a main body 501 and two sliding support portions 502 respectively connected to both ends of the main body 501; the transmission component 4 is provided with sliders 14 at corresponding positions of the two sliding support portions 502, and the sliders 14 are adapted to the sliding support portions 502 to form a sliding guide and limit for the transmission component 4.

[0058] See Figures 11-12 In this embodiment, the sliding support 502 has first sliding grooves 503 on both sides, and the transmission component 4 has mounting positions for mounting the slider 14 at both ends. The slider 14 and the transmission component 4 can be fixedly assembled by screws. The slider 14 has a second sliding groove 1401 at the corresponding position of the sliding groove. After the slider 14 and the sliding support 502 are engaged, the first sliding groove 503 and the second sliding groove 1401 form a mounting groove, and a rolling assembly 17 is provided in the mounting groove. The rolling assembly 17 includes a plurality of steel balls arranged in sequence and a retainer. This makes the transmission component 4 slide more smoothly and with less friction when it slides relative to the base 5. Moreover, in this embodiment, the sliding support 502 and the main body 501 extend in a straight line, which makes the structure of the base 5 and the transmission component 4 narrower, and the overall structure of the lock can also be narrower.

[0059] As another embodiment, the sliding guide structure between the slider 14 and the sliding support 502 can also adopt other methods. For example, it can adopt a method in which a groove and a convex rail cooperate with each other, or it can be like... Figure 14 As shown, the method of using the flanged track 505 and the guide groove 1402 is employed.

[0060] Furthermore, the sliding guide structure between the transmission component 4 and the base 5 can also be set in the width direction, but this will increase the width of the lock.

[0061] Meanwhile, a positioning structure 15 is also provided between the sliding support 502 and the slider 14. This positioning structure 15 is similar to the positioning structure 15 between the drive component 7 and the base 5. A positioning hole 504 is provided on the sliding support 502, and a positioning steel ball and a spring are provided on the slider 14, thereby realizing the positioning of the transmission component 4 in the unlocked position and the locked position.

[0062] See Figure 13 In this embodiment, the handle 1 has a receiving cavity 104, and the lock housing assembly 3 is disposed in the receiving cavity 104. The two ends of the handle 1 in the length direction are connected and fixed to the two ends of the transmission component 4 in the length direction. Fixed parts 406 perpendicular to the length direction are provided at both ends of the transmission component 4 in the length direction. When the lock housing assembly 3 is embedded in the receiving cavity 104 of the handle 1, the two ends of the handle 1 correspond to the fixed parts 406. At this time, the handle 1 and the transmission component 4 can be fixed by tightening screws.

[0063] Furthermore, this embodiment innovatively uses a push handle 1 to complete the unlocking and locking control of the lock, eliminating the need for traditional external components such as levers. This allows for diverse structural forms of the handle 1, making it more adaptable to sliding door profiles with extremely narrow frames. For example... Figure 13As shown, the handle 1 in this embodiment has a very simple structure, including a handle base 101 and a baffle 102. A receiving cavity 104 is disposed in the handle base 101, and the baffle 102 is disposed on the handle base 101. The baffle 102 and the handle base 101 are an integral structure, and the baffle 102 can be configured as a part with an appropriate protrusion 11 to facilitate the user to push and pull the door and window left and right. At the same time, a protrusion 103 is provided on the handle base 101, which is used for the installation of the lock cylinder.

[0064] In this embodiment, the transmission component 4 drives the locking tongue 6 to rotate to unlock and lock the lock, and the related structure of using the transmission component 4 to lock the locking tongue 6 in the locked state can all be found in the prior art. For example, the transmission between the locking tongue 6 and the transmission component 4 can be achieved by a gear and rack mechanism, or by other methods, such as the cooperation between the operating plate and the lock hook in the invention patent application with publication number CN101790616A.

[0065] The working process of the sliding handle lock in this embodiment is as follows: When the sliding handle 1 is slidable, it can drive the transmission component 4 to move, controlling the unlocking or locking of the lock. When the lock cylinder is turned with the key, it can control the unlocking, locking, or locking of the lock. The operating principle of the internal structure is the same whether the lock cylinder on the handle 1 controls the rotation of the first rotating component 901 or whether the outdoor lock cylinder controls the rotation of the driving component 7; the operating principle of the internal structure of the sliding handle 1 controlling the unlocking or locking of the lock is the same as that of the lock cylinder controlling the unlocking or locking of the lock.

[0066] Among them, such as Figure 7 As shown, the lock is currently in the unlocked state, with the bolt 6 retracted into the base 5. To switch to the locked state, push the handle 1 to the left, which will move the transmission component 4 to the left, causing the two bolts 6 to rotate and extend. The bolts 6, in conjunction with the lock seat, achieve the locking effect. Similarly, the lock cylinder drives the first rotating component 901 to rotate counterclockwise, completing the switch from the unlocked to the locked state. The diagram of the relevant components in the locked state is shown below. Figure 8As shown. During this process, since the cylinder 9011 of the first rotating member 901 is limited by the transmission component 4, the first rotating member 901 rotates counterclockwise and moves to the left along with the transmission component 4. Since the second rotating member 903 is connected to the driving member 7, and the driving member 7 is rotatably connected to the base 5 and restricted from moving, the driving member 7 will not have any other translational movements during the synchronous counterclockwise rotation. Similarly, the second rotating member 903 will only have the action of counterclockwise rotation. Therefore, as the transmission component 4 moves to the left, the linkage 9 will gradually become misaligned, and the first rotating member 901, the linkage 902, and the second rotating member 903 will no longer rotate coaxially. During this process, since the linkage 902 can move freely in the first direction relative to the first rotating member 901, and simultaneously can move freely in the second direction relative to the second rotating member 903; that is, from the perspective of the entire linkage 9, the linkage 902, located in the middle, plays a connecting role, and within the entire linkage 9, the linkage 902 has complete degrees of freedom in both directions on its plane of motion. Therefore, when the first rotating member 901 and the second rotating member 903 undergo translational motion along their rotation axes, the linkage 902 can adjust its position in real time to ensure that the first rotating member 901 and the second rotating member 903 can smoothly and synchronously transmit power. The positions of the first rotating member 901, the second rotating member 903, and the linkage 902 in the locked state are as follows: Figure 8 As shown.

[0067] See Figure 9 When switching to the locked state is required, it can only be controlled by the lock cylinder. Taking the lock cylinder on handle 1 as an example, in the locked state, it continues to rotate counterclockwise, causing the first rotating component 901, the linkage component 902, and the second rotating component 903 to rotate counterclockwise synchronously. During this process, since the transmission component 4 and the lock tongue 6 are limited, no translation occurs. At this time, the first rotating component 901 rotates on its own axis, and the linkage component 902 adjusts its own position to make the second rotating component 903 rotate synchronously, ultimately causing the driving component 7 to rotate synchronously counterclockwise. At this time, the driving boss 702 on the driving component 7 leaves the driving slot 401 on the transmission component 4 and finally abuts against the stop wall 404 of the transmission component 4. At the same time, the locking boss 405 on the transmission component 4 leaves the clearance slot 703 of the driving component 7 and is blocked by the locking surface 705 of the driving component 7, thus locking the transmission component 4. The positions of the first rotating component 901, the second rotating component 903, and the linkage component 902 in the locked state are as follows: Figure 9 As shown.

[0068] When it is necessary to unlock, it can only be done by controlling the lock cylinder, either by rotating the drive component 7 or the first rotating component 901. After the lock is released, it returns to the locked state, at which point it can be switched to the unlocked state by pushing the handle 1 or by controlling the lock cylinder.

[0069] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
