Description

Technical Field

[0001] This utility model relates to the field of door and window hardware accessories, and in particular to a handle structure and a pull rope lock including the handle. Background Technology

[0002] In the field of door lock technology, the pull-cord lock, as a special type of door lock, offers a new solution for locking and unlocking doors due to its unique lock cylinder layout and transmission method. Existing pull-cord locks mainly consist of a handle structure, a lock cylinder, and a transmission cord. In terms of structural design, the lock cylinder is usually cleverly positioned on the upper or lower side of the door leaf. This layout allows the lock tongue to be effectively hidden from the user's view, not only improving the overall aesthetics of the door lock but also enhancing its concealment and security to a certain extent. For details, please refer to [reference needed]. Figure 1 , Figure 1 A pull rope lock in the prior art is shown, wherein 100 indicates a handle structure, 200 indicates a lock cylinder, and 300 indicates a drive rope.

[0003] To achieve power transmission between the handle and the lock cylinder, a drive rope plays a crucial role. Because there is a spatial distance between the lock cylinder and the handle, and the structural characteristics of the door limit the use of rigid transmission components, a flexible drive rope is cleverly applied to this pull-rope lock system. The drive rope is wound around the door frame and connected to both the handle and the lock cylinder. When the user applies force to the handle, this force is converted into a vertical pulling force on the drive rope. The drive rope moves accordingly, driving the lock cylinder to move, thus achieving the locking or unlocking function of the door.

[0004] As the part directly operated by the user, the handle structure's design and operating logic have a significant impact on the user experience. A typical handle structure generally includes a housing, a handle, and a transmission component. The transmission component slides vertically within the housing and is designed to be located at the vertical edge of the door leaf for effective connection with the transmission rope. The handle is rotatably connected to the housing and establishes a transmission connection with the transmission component. When the user turns the handle, it drives the transmission component to move up and down, which in turn drives the lock cylinder via the transmission rope.

[0005] However, existing handle structures have significant shortcomings in terms of installation adaptability. When the assembled handle structure is installed on different sides of the door (inner or outer), significant differences in operation occur. Specifically, when the handle structure is installed on the inner side of the door (first installation state), its operation is preset to a specific mode; for example, turning the handle upwards opens the door, and turning it downwards closes the door. However, when usage needs change and the handle structure needs to be installed on the outer side of the door (second installation state), the handle structure needs to be rotated 180 degrees around the horizontal width of the door to ensure that the transmission component is located at the vertical edge of the door. This rotation fundamentally changes the operating logic of the handle structure; the original operation of turning the handle upwards to open the door and turning it downwards to close the door becomes turning the handle upwards to close the door and turning it downwards to open the door. This complete reversal of operating logic causes great confusion for users, especially those unfamiliar with the correspondence between the door lock installation state and the operating mode, easily leading to misoperation, affecting the normal use of the door lock, and reducing the user experience. Utility Model Content

[0006] In order to overcome at least one of the defects described in the prior art, the present invention provides a handle structure and a pull rope lock including the handle structure, so as to solve the problem that the operation logic of the existing pull rope lock handle structure is completely opposite when it is installed on different sides of the door leaf, which causes trouble for users and improves the user experience.

[0007] The technical solution adopted by this utility model to solve its problem is:

[0008] A handle structure for a pull-cord lock, the pull-cord lock including a lock cylinder and a drive cord for transmission connection, the handle structure including: a housing; a sliding member including a sliding body, a first connecting block and a second connecting block, the sliding body being slidably disposed on the housing, the first connecting block and the second connecting block being respectively connected to opposite sides of the sliding body, and the first connecting block and the second connecting block being arranged in a horizontal direction; a transmission member for transmission connection with the drive cord, the transmission member being detachably connected to the first connecting block and the second connecting block.

[0009] According to one embodiment of the present invention, the handle structure further includes a handle, which is rotatably connected to the housing and is connected to the sliding body via a transmission structure; when the handle rotates, the sliding body can be driven to slide up and down through the transmission structure; the axial direction of the handle's rotation axis is parallel to the arrangement direction of the first connecting block and the second connecting block.

[0010] According to one embodiment of the present invention, the housing is provided with a first sliding groove and a second sliding groove extending vertically; when the transmission member is detachably connected to the first connecting block, the transmission member is also slidably connected to the first sliding groove; when the transmission member is detachably connected to the second connecting block, the transmission member is also slidably connected to the second sliding groove.

[0011] According to one embodiment of the present invention, the housing is provided with a mounting cavity, the sliding body is slidably disposed in the mounting cavity, and the first connecting block and the second connecting block are also located in the mounting cavity; the transmission component includes a sliding arm and a transmission arm; the sliding arm is detachably connected to either the first connecting block or the second connecting block, and the transmission arm is used to connect to a transmission rope; when the sliding arm is detachably connected to the first connecting block, the sliding arm is slidably connected in the first sliding groove, and the transmission arm extends out of the first sliding groove in a direction away from the mounting cavity; when the sliding arm is detachably connected to the second connecting block, the sliding arm is slidably connected in the second sliding groove, and the transmission arm extends out of the first sliding groove in a direction away from the mounting cavity.

[0012] According to one embodiment of the present invention, both the first connecting block and the second connecting block extend vertically.

[0013] According to one embodiment of the present invention, both the first connecting block and the second connecting block are vertically connected to the sliding body.

[0014] According to one embodiment of the present invention, there are two sliding members and two transmission members; the handle structure further includes a transmission gear, and each of the sliding bodies of the two sliding members is provided with a rack portion. The two rack portions are arranged opposite to each other and respectively mesh with the transmission gear. The sliding bodies of the two sliding members can slide in opposite directions. The two transmission members and the two sliding members are connected in a one-to-one correspondence.

[0015] According to one embodiment of the present invention, the first connecting block is provided with a first fastening hole, and the second connecting block is provided with a second fastening hole; the transmission member is provided with a connecting hole; the handle structure further includes a fastener; when the transmission member is provided on the first connecting block, the fastener passes through the connecting hole and the first fastening hole; when the transmission member is provided on the second connecting block, the fastener passes through the connecting hole and the second fastening hole.

[0016] According to one embodiment of the present invention, the handle structure further includes an elastic structure, which is throttle-connected to the sliding member. The sliding body can move relative to the housing between a first position and a second position. The elastic structure is used to elastically drive the sliding body to move to the first position or the second position.

[0017] In addition, this utility model also provides a pull rope lock, including the handle structure as described above, and also including a lock cylinder and a transmission rope. The transmission rope is connected to the transmission component and the lock cylinder respectively.

[0018] In summary, the handle structure and the pull rope lock including it provided by this utility model have at least the following technical effects:

[0019] By simultaneously setting the first connecting block and the second connecting block, the installation position of the transmission component relative to the sliding body can be adjusted in the horizontal direction. This allows the handle structure in the first installation state to switch to the second installation state by simply rotating it 180 degrees around the vertical direction, and the handle structure in the second installation state to switch to the first installation state by simply rotating it 180 degrees around the vertical direction.

[0020] When the handle structure is in the first installation state installed on the inside of the door leaf, the first connecting block is used to be adjacent to the vertical edge of the door leaf, and the second connecting block is used to be set relatively away from the vertical edge of the door leaf. The transmission component of the first connecting block is detachably connected to the first connecting block to be located at the vertical edge of the door leaf, and then connected to the transmission rope.

[0021] When the handle structure is in the second installation state installed on the outside of the door leaf, the second connecting block is used to be adjacent to the vertical edge of the door leaf, and the first connecting block is used to be set relatively away from the vertical edge of the door leaf.

This adapts to different needs when the handle is installed on the inside or outside of the door, avoids misoperation problems caused by large differences in operation logic, and greatly improves the user experience.

[0031] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] 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 is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0034] The following is in conjunction with the appendix Figure 2-6 The present invention will be described in further detail below.

[0035] Please see Figures 2 to 4This utility model discloses a handle structure. Specifically, the handle structure is used for a pull rope lock. The pull rope lock includes a lock core and a transmission rope connected by a transmission connection. The handle structure includes a housing 1, a sliding member 2, and a transmission member 3. The sliding member 2 includes a sliding body 23, a first connecting block 21, and a second connecting block 22. The sliding body 23 is slidably disposed on the housing 1. The first connecting block 21 and the second connecting block 22 are respectively connected to opposite sides of the sliding body 23, and the first connecting block 21 and the second connecting block 22 are arranged in a horizontal direction. The transmission member 3 is used for transmission connection with the transmission rope. The transmission member 3 is detachably connected to the first connecting block 21 and the second connecting block 22.

[0036] Specifically, in this embodiment, the handle structure has a first installation state for installation on the inside of the door leaf and a second installation state for installation on the outside of the door leaf; when the handle structure is in the first installation state, the first connecting block 21 is disposed adjacent to the vertical edge of the door leaf, and the second connecting block 22 is disposed relatively away from the vertical edge of the door leaf; when the handle structure is in the second installation state, the second connecting block 22 is disposed adjacent to the vertical edge of the door leaf, and the first connecting block 21 is disposed relatively away from the vertical edge of the door leaf.

[0037] The handle structure provided in this embodiment, by simultaneously setting the first connecting block 21 and the second connecting block 22, can adjust the installation position of the transmission member 3 relative to the sliding body 23 in the horizontal direction, so that the handle structure in the first installation state only needs to be rotated 180 degrees around the vertical direction to switch to the second installation state, and the handle structure in the second installation state only needs to be rotated 180 degrees around the vertical direction to switch to the first installation state.

[0038] When the handle structure is in the first installation state installed on the inside of the door leaf, the first connecting block 21 is used to be adjacent to the vertical edge of the door leaf, and the second connecting block 22 is used to be set relatively away from the vertical edge of the door leaf. The transmission component 3 of the first connecting block 21 is detachably connected to the first connecting block 21 so as to be located at the vertical edge of the door leaf, and then connected to the transmission rope.

[0039] When the handle structure is in the second installation state installed on the outside of the door leaf, the second connecting block 22 is used to be adjacent to the vertical edge of the door leaf, and the first connecting block 21 is used to be set relatively away from the vertical edge of the door leaf. The transmission component 3 is detachably connected to the second connecting block 22 so as to be located at the vertical edge of the door leaf, and then connected to the transmission rope for transmission.

[0040] In this way, regardless of which side of the door the handle structure is installed on, the user can control the movement of the lock cylinder through similar operation methods (such as turning handle 4 upwards to open the door and turning it downwards to close the door). This adapts to different needs when the handle structure is installed on the inside or outside of the door, avoids misoperation problems caused by large differences in operation logic, and greatly improves the user experience.

[0041] It is understood that in this embodiment, when the handle structure is installed on the door leaf, the horizontal arrangement direction of the first connecting block 21 and the second connecting block 22 is also the horizontal width direction of the door leaf.

[0042] like Figure 3 and Figure 4 As shown, in one embodiment, the first connecting block 21 is provided with a first fastening hole 211, and the second connecting block 22 is provided with a second fastening hole 221; the transmission member 3 is provided with a connecting hole 33; the handle structure also includes a fastener 6; when the transmission member 3 is provided on the first connecting block 21, the fastener 6 passes through the connecting hole 33 and the first fastening hole 211 to fix the transmission member 3 on the first connecting block 21; when the transmission member 3 is provided on the second connecting block 22, the fastener 6 passes through the connecting hole 33 and the second fastening hole 221 to fix the transmission member 3 on the second connecting block 22. Thus, using the fastener 6 to connect the transmission member 3 to the first connecting block 21 or the second connecting block 22 is simple and convenient. In actual installation, it is only necessary to select whether the handle structure is installed on the inside of the door leaf (first installation state) or the outside (second installation state), place the transmission member 3 on the corresponding connecting block, and then use the fastener 6 to pass through the connecting hole 33 and the corresponding fastening hole in sequence for fixation. The entire installation process does not require complicated tools and operating steps, reducing installation difficulty and time costs. Meanwhile, this detachable connection method also makes the handle structure more flexible when the installation position needs to be changed or maintenance is required. When the user's needs change and the handle structure needs to be switched from the inside of the door leaf to the outside or vice versa, simply remove the fastener 6, remove the transmission component 3 from the current connecting block, reinstall it on another connecting block and fix it with the fastener 6 again. There is no need to disassemble and reassemble the entire handle structure on a large scale, which greatly improves the convenience and flexibility of operation.

[0043] It should be noted that in some other embodiments, the transmission component 3 may be connected to the first connecting block 21 or the second connecting block 22 by means of a snap-fit ​​structure or a pin-fit structure. The choice can be made according to actual needs and is not limited here.

[0044] like Figure 2 , Figure 3 and Figure 4As shown, in one embodiment, the housing 1 has a vertically extending first groove 11 and a second groove 12; when the transmission member 3 is detachably connected to the first connecting block 21, the transmission member 3 is also slidably connected to the first groove 11; when the transmission member 3 is detachably connected to the second connecting block 22, the transmission member 3 is also slidably connected to the second groove 12. Thus, on the one hand, either the first slide groove 11 or the second slide groove 12 provides a precise guide track for the transmission component 3, ensuring that the transmission component 3 always moves along the predetermined vertical direction during the up-and-down sliding process without deviation or shaking. This precise guiding effect ensures a stable and reliable transmission relationship between the transmission component 3 and the transmission rope, allowing the tension on the transmission rope to be accurately transmitted to the lock cylinder, thereby improving the accuracy of the lock cylinder's opening and closing actions, reducing door lock opening or closing failures caused by transmission instability, and improving the overall performance of the pull rope lock. On the other hand, when assembling the handle structure, the sliding connection between either the first slide groove 11 or the second slide groove 12 and the transmission component 3 simplifies the installation steps. Installers only need to connect the transmission component 3 to the corresponding connecting block and ensure that the transmission component 3 can smoothly slide into the corresponding slide groove to complete the installation. This simple installation method reduces the installation difficulty, improves installation efficiency, and reduces the risk of door lock failure due to improper installation. At the same time, the guiding effect of the slide groove also helps installers quickly and accurately locate the position of the transmission component 3, ensuring installation quality.

[0045] like Figure 3 and Figure 4 As shown, in one embodiment, both the first connecting block 21 and the second connecting block 22 extend vertically. This results in a smaller horizontal space occupied by the vertically extending first connecting block 21 and second connecting block 22, making the overall horizontal structure of the handle more compact. This is significant for areas with limited installation space, such as door panels. Specifically, when installing the handle structure, the vertical first connecting block 21 and second connecting block 22 will not excessively occupy space on the edge of the door panel, allowing the handle structure to better adapt to door panels of different sizes and shapes, providing greater flexibility for door lock installation. Simultaneously, the compact structure also helps reduce interference between the handle structure and other door components (such as the door frame, handle trim, etc.), reducing installation difficulty and the incidence of problems during installation.

[0046] It should be noted that in some other embodiments, the first connecting block 21 and the second connecting block 22 may also extend laterally or obliquely, depending on the actual needs, and are not limited to one specific embodiment.

[0047] like Figure 3 and Figure 4As shown, in one embodiment, both the first connecting block 21 and the second connecting block 22 extend vertically, and both are vertically connected to the sliding body 23. This configuration allows for several advantages. First, when the user operates the handle structure to move the transmission component 3, the force is directly and quickly transmitted from the sliding body 23 to the first connecting block 21 or the second connecting block 22 via the vertical connection. This reduces force loss and offset during transmission. Compared to inclined or non-vertical connections, vertical connections minimize force decomposition caused by connection angle deviations, ensuring the transmission component 3 receives a stable and accurate driving force. This effectively avoids problems such as jamming and shaking of the transmission component 3 caused by poor force transmission, ensuring the accuracy and reliability of the handle structure's transmission. Second, the vertical connection and the vertically extending first connecting block 21 and second connecting block 22 have relatively simple structures. Mature processing techniques such as casting, forging, and machining can be used in their manufacturing. This simple structure reduces manufacturing difficulty and cost, and improves production efficiency.

[0048] It should be noted that in some other embodiments, the first connecting block 21 and the second connecting block 22 can also be tilted and connected to the sliding body 23 according to actual needs, which can be set according to actual needs.

[0049] like Figure 3 As shown, in one embodiment, the housing 1 is provided with a mounting cavity 13, the sliding body 23 is slidably disposed in the mounting cavity 13, and the first connecting block 21 and the second connecting block 22 are also located in the mounting cavity 13; the transmission component 3 includes a sliding arm 31 and a transmission arm 32; the sliding arm 31 is detachably connected to either the first connecting block 21 or the second connecting block 22, and the transmission arm 32 is used to connect with a transmission rope; when the sliding arm 31 is detachably connected to the first connecting block 21, the sliding arm 31 is slidably connected in the first slide groove 11, and the transmission arm 32 extends out of the first slide groove 11 in a direction away from the mounting cavity 13; when the sliding arm 31 is detachably connected to the second connecting block 22, the sliding arm 31 is slidably connected in the second slide groove 12, and the transmission arm 32 extends out of the first slide groove 11 in a direction away from the mounting cavity 13. Thus, on the one hand, by rationally accommodating each component in the mounting cavity 13, the space within the mounting cavity 13 is fully utilized. Each component is set up in the mounting cavity 13 according to a specific layout and movement trajectory, reducing space waste. At the same time, the relative positional relationship between each component is more stable, which helps to improve the stability and reliability of the transmission. On the other hand, by extending the transmission arm 32 of the transmission component 3 outside the mounting cavity 13, while hiding the sliding arm 31 and the like in the corresponding first slide groove 11 or second slide groove 12, both the realization of the transmission function and the security of the door lock are ensured.

[0050] like Figure 3As shown, in one embodiment, the sliding arm 31 is provided with the aforementioned connection hole 33.

[0051] like Figure 4 , Figure 5 and Figure 6 As shown, in one embodiment, the handle structure further includes a handle 4, which is rotatably connected to the housing 1. The handle 4 is connected to the sliding body 23 via a transmission structure. When the handle 4 rotates, it can drive the sliding body 23 to slide up and down through the transmission structure. The axial direction of the rotating shaft 41 of the handle 4 is parallel to the arrangement direction of the first connecting block 21 and the second connecting block 22. It can be understood that the first connecting block 21 and the second connecting block 22 are selectively arranged adjacent to the vertical edge of the door leaf during installation, and the horizontal arrangement direction of the first connecting block 21 and the second connecting block 22 is also the horizontal direction of the door leaf. In the width direction, the axis of the pivot 41 of the handle 4 is designed to be parallel to the arrangement direction of the first connecting block 21 and the second connecting block 22. This can achieve the goal of making the operation logic of the handle structure in the first installation state consistent with the operation logic of the handle structure in the second installation state. For example, regardless of which side of the door leaf the handle structure is installed on, the operation logic can be designed so that turning the handle 4 upwards unlocks the door and turning the handle 4 downwards locks the door. Alternatively, the operation logic can be designed so that turning the handle 4 downwards locks the door and turning the handle 4 upwards unlocks the door.

[0052] like Figure 4 , Figure 5 and Figure 6 As shown, in one embodiment, the handle 4 is fixed to the rotating shaft 41, which is rotatably connected to the housing 1. The transmission structure between the handle 4 and the sliding body 23 includes a cam 8 and a transmission groove 25. The cam 8 is fixed to the rotating shaft 41, and the transmission groove 25 is formed in the sliding body 23. The cam 8 has a drive end 81 that is offset from the axis of the rotating shaft 41. The drive end 81 is connected to the transmission groove 25. Thus, when the handle 4 rotates, it can drive the drive end 81 to make a circular motion. Under the transmission of the drive end 81 and the transmission groove 25, the sliding body 23 slides up and down relative to the housing 1. In this way, no additional gear meshing or complex linkage mechanism is required, which reduces friction and energy loss during the transmission process, and allows the energy of the handle 4 rotation to be converted into the sliding energy of the sliding body 23 more directly and effectively, thus significantly improving the transmission efficiency.

[0053] It should be noted that in some other embodiments, the transmission structure between the handle 4 and the sliding body 23 may be, but is not limited to, a crank-slider mechanism or a gear and rack mechanism, etc., which can be selected according to actual needs, and is not limited here.

[0054] like Figure 3 and Figure 4As shown, in one embodiment, there are two sliding members 2 and two transmission members 3; the handle structure also includes a transmission gear 5, and each sliding body 23 of the two sliding members 2 is provided with a rack portion 24. The two rack portions 24 are arranged opposite to each other and respectively mesh with the transmission gear 5. The sliding bodies 23 of the two sliding members 2 can slide in opposite directions. The two transmission members 3 and the two sliding members 2 are connected one-to-one. Specifically, when the handle structure is in the first installation state, the first connecting blocks 21 of the two transmission members 3 and the two sliding members 2 are connected one-to-one. When the handle structure is in the second installation state, the second connecting blocks 22 of the two transmission members 3 and the two sliding members 2 are connected one-to-one. In this way, the transmission ropes at the upper and lower positions can be pulled at the same time, thereby simultaneously driving the lock cylinder located on the upper side and the lower side of the door leaf.

[0055] In one embodiment, the aforementioned transmission gear 5 is rotatably connected to the mounting cavity 13 via a gear shaft.

[0056] like Figure 4 , Figure 5 and Figure 6 As shown, in one embodiment, the handle structure further includes an elastic structure 7, which is connected to the sliding member 2. The sliding body 23 can move relative to the housing 1 between a first position and a second position. Specifically, when the sliding body 23 moves to the first position, the transmission member 3 moves to a position that switches the lock cylinder to the locked state; when the sliding body 23 moves to the second position, the transmission member 3 moves to a position that switches the lock cylinder to the unlocked state. The elastic structure 7 is used to elastically drive the sliding body 23 to move to the first or second position. Thus, when the user applies external force to turn the handle 4, the elastic structure 7 first stores some energy and releases it at an appropriate time to assist the sliding body 23 in moving, thereby reducing the force that the user needs to continuously apply and making the operation more effortless. This advantage is particularly obvious for users with less strength or in scenarios where frequent unlocking and locking are required.

[0057] It should be noted that in some other embodiments, when the sliding body 23 moves to the first position, the transmission member 3 moves to the position that switches the lock cylinder to the unlocked state, and when the sliding body 23 moves to the second position, the transmission member 3 moves to the position that switches the lock cylinder to the locked state; the design can be made according to actual needs.

[0058] like Figure 4 , Figure 5 and Figure 6As shown, in one embodiment, the elastic structure 7 includes a spring piece 71 and a rotating member 72. The rotating member 72 is fixed to the pivot 41 of the handle 4. The spring piece 71 is vertically arranged. The outer wall of the rotating member 72 includes two oppositely arranged convex arc surfaces 721 and two oppositely arranged limiting planes 722. The limiting planes 722 are connected between the two convex arc surfaces 721. The spring piece 71 abuts against the outer wall of the rotating member 72. When the spring piece 71 abuts against the convex arc surface 721, the spring piece 71 will apply a force to the rotating member 72 to make the rotating member 72 rotate. The spring piece 71 directly abuts against the limiting plane 722, so as to achieve the purpose of elastically driving the sliding body 23 to move to the first position or the second position.

[0059] It should be noted that in some other embodiments, the elastic structure 7 may also include, but is not limited to, torsion springs, etc., depending on the actual situation, and is not limited to here.

[0060] In addition, this utility model embodiment also provides a pull rope lock, including the handle structure as described in any of the above embodiments, and also including a lock cylinder and a transmission rope. The transmission rope is connected to the transmission component 3 and the lock cylinder respectively. Under the drive of the transmission component 3, the transmission rope can drive the lock cylinder to switch between the locked position and the unlocked position.

[0061] In summary, the handle structure and the pull cord lock including it disclosed in this utility model can bring at least the following beneficial technical effects:

[0062] 1) Regardless of which side of the door leaf the handle structure is installed on, users can control the movement of the lock cylinder through similar operation methods, thereby adapting to different needs whether the handle structure is installed on the inside or outside of the door leaf, avoiding misoperation problems caused by large differences in operation logic, and greatly improving the user experience.

[0063] 2) When the user’s needs change and the handle structure needs to be switched from the inside of the door leaf to the outside or vice versa, simply remove the fastener 6, remove the transmission component 3 from the current connecting block, reinstall it on another connecting block and fix it with the fastener 6 again. There is no need to disassemble and reassemble the entire handle structure on a large scale, which greatly improves the convenience and flexibility of operation.

[0064] 3) One of the first slide groove 11 and the second slide groove 12 provides a precise guide track for the transmission component 3, ensuring that the transmission component 3 always moves along the predetermined vertical direction during the up and down sliding process, without deviation or shaking. This precise guiding effect can ensure that the transmission relationship between the transmission component 3 and the transmission rope is stable and reliable, so that the tension on the transmission rope can be accurately transmitted to the lock core.

[0065] 4) The vertically extending first connecting block 21 and second connecting block 22 occupy less space in the horizontal direction, making the overall structure of the handle structure more compact in the horizontal direction, which is of great significance for parts with limited installation space such as door panels.
