Description

Technical Field

[0001] The invention relates to the technical field of sliding door accessories, and in particular to a sliding door handle structure. Background Art

[0002] With the continuous advancement of modern architectural design and people's increasing safety awareness, the safety and convenience of sliding doors, as a common component connecting indoor and outdoor, have become the focus of consumers' attention. The traditional sliding door handle design is mostly limited to both sides of the door body, usually only equipped with an unlocking mechanism on the inside of the door, and the outside does not have the function of direct opening. Although such a design improves safety to a certain extent, it also brings inconvenience in use.

[0003] In addition, the existing sliding door handle structure also has some limitations during installation and use. For example, since the handle is usually installed on both sides of the door, different handle structures need to distinguish between the inside and outside of the door, which leads to the problem of inverted installation positions; and due to the different handle structures, the inner and outer handle structures need to be molded separately during production, which increases the production cost. Summary of the invention

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a sliding door handle structure, which can solve the unlocking problem, simplify assembly, and avoid the problem of inverted installation.

[0005] The technical solution adopted by the present invention to solve the problem is:

[0006] A sliding door handle structure, comprising: a first handle shell, the first handle shell being assembled on one side of the sliding door, the first handle shell being provided with a first sliding portion arranged in a vertical direction, the first sliding portion being slidably provided with a first triggering member; a second handle shell, the second handle shell being mirror-symmetrical with the first handle shell on both sides of the sliding door, the second handle shell being assembled on the other side of the sliding door, the second handle shell being provided with a second sliding portion arranged in a vertical direction, the second sliding portion being mirror-symmetrical with the first sliding portion on both sides of the sliding door, the second sliding portion being slidably provided with a second triggering member, the second triggering member The first trigger member is mirror-symmetrical with the first trigger member on both sides of the sliding door; a synchronous member, which slides longitudinally along the side wall of the sliding door, and moves synchronously with the first trigger member and the second trigger member, and the part of the synchronous member connected to the first trigger member and the part connected to the second trigger member are symmetrical to each other; a locking member, which is connected to the top of the synchronous member and is used to lock with the track or door frame above the sliding door; wherein the first handle shell, the second handle shell and the synchronous member are divided into an upper half and a lower half based on the plane where the midline of the horizontal direction of the first handle shell is located, and the upper half and the lower half are symmetrical to each other.

[0007] By adopting the above scheme and designing the synchronizing parts and the locking parts, the locking and unlocking states of the locking parts can be synchronously controlled both inside and outside the door by operating the respective handle shells, which not only maintains the safety of the door under normal circumstances, but also provides the possibility of directly opening the door from the outside in an emergency, thereby improving convenience and escape efficiency. Since the first handle shell and the second handle shell are symmetrically designed and are both connected to the locking parts through the synchronizing parts, their installation positions can be interchanged without affecting the functions, which avoids the problem of inverted installation positions. At the same time, since the first handle shell and the second handle shell have exactly the same structure, they can be produced using the same set of molds, which greatly reduces the production cost and realizes standardized production.

[0008] Furthermore, a vertical frame is provided between the synchronous member and the sliding door, the vertical frame is mounted on the side wall of the sliding door, a vertical track is provided on the side of the vertical frame away from the sliding door, and the synchronous member is slidably provided on the vertical track.

[0009] By adopting the above solution, the vertical frame is installed on the side wall of the sliding door, providing a stable support structure for the synchronous member, which can effectively prevent the synchronous member from deviating or shaking during the sliding process, thereby improving the stability and reliability of the entire handle structure.

[0010] Furthermore, the synchronization component includes: a sliding plate, which is slidably arranged on the vertical track; a first linkage arm, one end of which is connected to the sliding plate, and the other end of which passes through the vertical frame and is engaged with the first trigger component; a second linkage arm, one end of which is connected to the sliding plate, and the other end of which passes through the vertical frame and is engaged with the second trigger component.

[0011] By adopting the above solution, the sliding plate is responsible for sliding on the vertical track to achieve longitudinal movement. The first linkage arm and the second linkage arm respectively connect the sliding plate and the first trigger member and the second trigger member to achieve mechanical linkage between them. When the trigger member on one side is operated, it will push or pull the sliding plate to slide on the vertical track through the corresponding linkage arm, and then drive the trigger member on the other side to move synchronously through the linkage arm on the other side.

[0012] Furthermore, a first hollow hole is provided in the center of the sliding plate, a second hollow hole is provided in the vertical frame, a limit block is provided in the second hollow hole, and the limit block is provided with a sliding block extending into the first hollow hole to limit the longitudinal sliding distance of the sliding plate along the vertical track.

[0013] By adopting the above solution, the second hollow hole is arranged on the vertical frame to provide an installation space for the limit block. The sliding block can contact the edge of the first hollow hole during the sliding process of the sliding plate, thereby limiting the longitudinal sliding distance of the sliding plate along the vertical track, ensuring that the sliding plate can stop sliding when reaching a predetermined position, avoiding structural damage or functional failure caused by excessive sliding.

[0014] Furthermore, a first limiting structure for abutting against one side of the limiting block is provided between the first linkage arm and the second linkage wall of the synchronizer, and a second limiting structure for abutting against the other side of the limiting block is provided in the first hollow hole.

[0015] By adopting the above solution, the lateral displacement of the synchronous part during the sliding process is limited, and by adding the first limiting structure and the second limiting structure, the design further enhances the stability of the handle structure. It ensures that the synchronous part can remain stable during the sliding process, avoids safety hazards caused by structural looseness or functional abnormality, helps users to control the locking or unlocking state more accurately, and improves the user experience.

[0016] Furthermore, the synchronizer is centrally symmetrical with the midpoint of the first hollow hole as a reference.

[0017] By adopting the above solution, even after the synchronization component is integrated with the first handle housing and the second handle housing, it can still be assembled with the sliding door after being reversed as a whole, without paying special attention to the installation sequence and whether the inner and outer handles are installed reversely.

[0018] Furthermore, an assembly groove is provided on the side of the vertical frame facing the sliding door, and the assembly groove is used to engage with the sliding door. Avoidance grooves are provided in the assembly groove corresponding to the first handle shell and the second handle shell, so that the first handle shell and the second handle shell can be inserted into the assembly groove at the same time after being assembled with the sliding door.

[0019] By adopting the above solution, a quick and stable connection can be achieved by inserting the handle housing into the assembly groove, reducing the complexity and time cost of the installation process; the clamping method between the assembly groove and the sliding door enhances the stability of the handle structure. This design makes the handle structure not easy to loosen or fall off during long-term use, thereby ensuring the reliability and safety of the handle function; the setting of the avoidance groove ensures that the first handle housing and the second handle housing can be smoothly inserted into the assembly groove during the assembly process. The shape and size of the avoidance groove match the shape of the handle housing, avoiding installation difficulties or damage caused by size discrepancies. It can also ensure that the handle housing remains flat and beautiful with the surface of the sliding door after installation. It helps to improve the visual effect and user experience of the entire door and window product

[0020] Furthermore, the first sliding part and the second sliding part are both vertically arranged waist-shaped sliding grooves, a third hollow hole is arranged in the waist-shaped sliding groove, and the first trigger member and the second trigger member are both provided with an operating position extending into the third hollow hole.

[0021] By adopting the above solution, the user can conveniently operate the trigger member to open or close the handle structure, thereby improving the convenience and accuracy of the operation.

[0022] Furthermore, a clamping mechanism is provided at the edges of the first sliding part and the second sliding part, and the clamping mechanism is clamped with a limiting plate, a space for limiting the sliding of the first trigger member is formed between the limiting plate and the first sliding part, and a space for limiting the sliding of the second trigger member is formed between the limiting plate and the second sliding part, a fourth hollow hole is provided on the limiting plate, and the first trigger member and the second trigger member are both provided with a clamping position extending out of the fourth hollow hole, and the clamping position is used to clamp with the synchronization member.

[0023] By adopting the above solution, the sliding range of the first trigger member and the second trigger member can be effectively limited to prevent them from being damaged or failing due to excessive sliding. It provides stable sliding restriction and linkage functions, ensuring the reliability and safety of the handle structure.

[0024] Furthermore, the first handle housing and the second handle housing are provided with a sliding portion for driving the sliding door to move.

[0025] By adopting the above solution, the sliding door can be moved by holding the sliding part and applying a pushing force or a pulling force, which provides an intuitive and convenient operation method, allowing the user to easily move the sliding door.

[0026] In summary, the sliding door handle structure provided by the present invention has the following technical effects:

[0027] 1. The locking and unlocking status of the locking parts can be synchronously controlled by operating the respective handle housings from inside and outside the door. This not only maintains the safety of the door under normal circumstances and prevents unauthorized access, but also provides the possibility of opening the door directly from outside in an emergency, thereby greatly improving convenience and escape efficiency;

[0028] 2. Since the first handle housing and the second handle housing are designed symmetrically and are both connected to the locking member through a synchronizing member, their installation positions can be interchanged without affecting the function. This design avoids the problem of position reversal that may occur during installation, simplifies the assembly process, and reduces the difficulty and error rate of installation;

[0029] 3. Since the structures of the first handle housing and the second handle housing are exactly the same, it means that they can be produced using the same set of molds. This not only simplifies the production process, but also greatly reduces production costs, realizes standardized production, and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to facilitate the understanding of the embodiments of the present invention, the following will be further explained by taking specific embodiments as examples in conjunction with the drawings, and each embodiment does not constitute a limitation on the embodiments of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0041] Embodiment 1 of the present invention refers to Figure 1-Figure 6As shown, a sliding door handle structure is disclosed, including a first handle housing 1, a second handle housing 2, a synchronization member 3 and a locking member 4. The first handle housing 1 is assembled on one side of the sliding door 5, and a first sliding portion 11 arranged in a vertical direction is provided on the first handle housing 1, and a first triggering member 12 is slidably provided on the first sliding portion 11; the second handle housing 2 is assembled on the other side of the sliding door 5, and a second sliding portion 21 arranged in a vertical direction is provided on the second handle housing 2, and a second triggering member 22 is slidably provided on the second sliding portion 21. In order to reduce production costs, firstly, the second handle housing 2 and the first handle housing 1 are mirror-symmetrical on both sides of the sliding door 5, and the first handle housing 1 and the second handle housing 2 are mirror-symmetrical on both sides of the sliding door 5, and the structures of the two are symmetrical and completely the same. The ingenuity of this design is that it allows the use of the same set of molds for mass production, thereby greatly reducing production costs. The sharing of mold costs has significantly reduced the production cost of each component. At the same time, the standardized production process has also improved production efficiency, because workers can quickly master and efficiently complete the production of the same component, reducing the time for training and familiarization with new molds. Secondly, the second sliding part 21 is mirror-symmetrical with the first sliding part 11 on both sides of the sliding door 5, and the second trigger member 22 is mirror-symmetrical with the first trigger member 12 on both sides of the sliding door 5, so that the first trigger member 12 and the second trigger member 22 can be seamlessly assembled and move synchronously with the synchronizer 3 no matter which side of the handle housing they are installed on. This feature greatly reduces the difficulty of installation and improves the flexibility and accuracy of installation. At the same time, since the connection parts of the synchronizer 3 and the two triggering parts are symmetrical, there is no need to worry about the installation order or the distinction between the inner and outer door handles, which further simplifies the installation process and improves the installation efficiency; the synchronizer 3 slides longitudinally along the side wall of the sliding door 5, and the synchronizer 3 moves synchronously with the first triggering part 12 and the second triggering part 22. The part of the synchronizer 3 connected to the first triggering part 12 and the part connected to the second triggering part 22 are symmetrical, so that the first triggering part 12 and the second triggering part 22 can be assembled and move synchronously with the synchronizer 3 regardless of whether they are installed on the first handle housing 1 or the second handle housing 2 during the installation process, which greatly reduces the difficulty of installation. The locking part 4 is connected to the top of the synchronizer 3 and is used to lock with the track or door frame above the sliding door 5, so that the locking and unlocking states of the locking part 4 can be synchronously controlled by operating the respective handle housings inside and outside the door. This design not only ensures the safety of the door under normal circumstances, but also provides the possibility of opening the door directly from the outside in an emergency, thereby improving convenience and escape efficiency. This double protection design enables the handle structure to achieve a perfect balance between safety and convenience.Finally, the first handle housing 1, the second handle housing 2 and the synchronizer 3 are divided into an upper part and a lower part based on the plane where the median line of the first handle housing 1 is located, and the upper part and the lower part are symmetrical to each other. Due to the symmetry of the upper part and the lower part, the two can be assembled on both sides of the folding door after the positions are interchanged, without considering the installation sequence of the two handles, and without distinguishing the handles of the inner and outer doors, thereby improving the installation efficiency and preventing the problem of wrong installation. By designing the synchronizer 3 and the locking member 4, the locking and unlocking states of the locking member 4 can be synchronously controlled by operating the respective handle housings inside and outside the door, which not only maintains the safety of the door under normal circumstances, but also provides the possibility of opening the door directly from the outside in an emergency, thereby improving the convenience and escape efficiency. Since the first handle housing 1 and the second handle housing 2 are symmetrically designed and are both connected to the locking member 4 through the synchronizer 3, the installation positions between them can be interchanged without affecting the function, which avoids the problem of inverted installation positions.

[0042] It should be noted that the locking member 4 can be a locking rod that moves synchronously with the synchronous member 3. The locking rod can move upward directly to be inserted into the track or door frame above the sliding door 5 to complete the locking. The locking member 4 can also be a lock set at the top of the sliding door 5. The lock tongue of the lock set is linked with the synchronous member 3, so that when the synchronous member 3 moves upward, it can drive the lock tongue to move upward and be inserted into the track or door frame above the sliding door 5 to complete the locking.

[0043] Usually, a door frame is provided at the edge of the sliding door 5, so in some embodiments, a vertical frame 6 is provided between the synchronous member 3 and the sliding door 5, the vertical frame 6 is mounted on the side wall of the sliding door 5, and a vertical track 61 is provided on the side of the vertical frame 6 away from the sliding door 5, and the synchronous member 3 is slidably arranged on the vertical track 61. The vertical frame 6 is mounted on the side wall of the sliding door 5, providing a stable supporting structure for the synchronous member 3, which can effectively prevent the synchronous member 3 from deflecting or shaking during the sliding process, thereby improving the stability and reliability of the entire handle structure. Specifically, the vertical frame 6 is provided with a mounting groove 62 on one side facing the sliding door 5, and the mounting groove 62 is used for clamping with the sliding door 5. The mounting groove 62 is provided with a avoidance groove 63 corresponding to the first handle housing 1 and the second handle housing 2, so that the first handle housing 1 and the second handle housing 2 can be inserted into the mounting groove 62 at the same time after being assembled with the sliding door 5. By inserting the handle housing into the mounting groove 62, a quick and stable connection can be achieved, reducing the complexity and time cost during the installation process; the clamping mode between the mounting groove 62 and the sliding door 5 enhances the stability of the handle structure. This design makes the handle structure not easy to loosen or fall off during long-term use, thereby ensuring the reliability and safety of the handle function; the setting of the avoidance groove 63 ensures that the first handle housing 1 and the second handle housing 2 can be smoothly inserted into the mounting groove 62 during the assembly process. The shape and size of the avoidance groove 63 match the shape of the handle housing, avoiding installation difficulties or damage caused by size mismatch. It can also ensure that the handle housing and the surface of the sliding door 5 remain flat and beautiful after installation, which helps to improve the visual effect and user experience of the entire door and window product.

[0044] Due to the clever design of the avoidance groove 63, this innovative feature makes the sliding door handle structure show extremely high flexibility and adaptability. Specifically, no matter how the structure of the vertical frame 6 changes with the design requirements of different sliding doors 5, it can smoothly achieve seamless plug-in with one end of the first handle housing 1 and the second handle housing 2. This design not only ensures the rapidity of installation, but also greatly improves the stability of installation, making the entire installation process both efficient and reliable. More importantly, the existence of the avoidance groove 63 eliminates the assembly differences that may be caused by changes in the structure of the vertical frame 6. This means that no matter how the structure of the sliding door 5 or the vertical frame 6 is adjusted, the handle structure can adapt perfectly without additional modification or adjustment. This design makes the product widely applicable to various types of sliding doors, thereby greatly improving the versatility and market competitiveness of the product. In general, by introducing the innovative design of the avoidance groove 63, the sliding door handle structure successfully overcomes the limitations of the traditional handle structure in terms of adaptability. It can not only easily cope with the diverse needs of sliding doors and vertical frame structures, but also provide users with a more convenient and efficient installation experience. This design not only reflects the ultimate pursuit of product details, but also fully demonstrates the outstanding ability in technological innovation.

[0045] In order to facilitate the synchronous movement of the synchronizer 3 and the first trigger member 12 and the second trigger member 22, a second hollow hole 64 is provided in the vertical frame 6. The synchronizer 3 includes a sliding plate 31, a first linkage arm 32 and a second linkage arm 33. The sliding plate 31 is slidably arranged on the vertical track 61. Preferably, the vertical track 61 is an outwardly convex track. The edge of the sliding plate 31 is provided with a clamping edge 311 for clamping with the track. In the present embodiment 1, the structure between the vertical track 61 and the clamping edge 311 is L-shaped. In other embodiments, the specific shapes of the two are not limited, and they can be adapted to be clamped. A first hollow hole 312 is provided in the center of the sliding plate 31, and the synchronizer 3 is symmetrical with the midpoint of the first hollow hole 312 as the reference center. With this arrangement, even if the synchronizer 3 is integrated with the first handle housing 1 and the second handle housing 2, it can still be assembled with the sliding door 5 after the overall inversion, without paying special attention to the installation sequence and whether the inner and outer handles are installed in reverse.

[0046] A limit block 34 is provided in the second hollow hole 64. Preferably, the limit block 34 is provided with a clamping edge 311 at both ends, and the clamping edge 311 is clamped and fixed with the top and bottom of the second hollow hole 64. The limit block 34 is provided with a sliding block 341 extending into the first hollow hole 312 to limit the longitudinal sliding distance of the sliding plate 31 along the vertical track 61. The second hollow hole 64 is provided on the vertical frame 6 to provide an installation space for the limit block 34. The sliding block 341 can contact the edge of the first hollow hole 312 during the sliding process of the sliding plate 31, thereby limiting the longitudinal sliding distance of the sliding plate 31 along the vertical track 61, ensuring that the sliding plate 31 can stop sliding when reaching a predetermined position, and avoiding structural damage or functional failure caused by excessive sliding. One end of the first linkage arm 32 is connected to the sliding plate 31, and the other end passes through the vertical frame 6 to engage with the first trigger member 12. One end of the second linkage arm 33 is connected to the sliding plate 31, and the other end passes through the vertical frame 6 to engage with the second trigger member 22. The sliding plate 31 is responsible for sliding on the vertical track 61, thereby realizing longitudinal movement. The first linkage arm 32 and the second linkage arm 33 are respectively connected to the sliding plate 31 and the first trigger member 12 and the second trigger member 22, realizing mechanical linkage between them. When the trigger member on one side is operated, it will push or pull the sliding plate 31 to slide on the vertical track 61 through the corresponding linkage arm, and then drive the trigger member on the other side to move synchronously through the linkage arm on the other side. Preferably, the first linkage arm 32 and the second linkage wall are symmetrically and parallelly arranged, and the spacing distance between the first linkage arm 32 and the second linkage wall is less than or equal to the lateral distance of the second hollow hole 64. And after the limit block 34 is installed in the second hollow hole 64, there is still a space reserved for the first linkage arm 32 and the second linkage wall to pass through.

[0047] In order to improve the longitudinal sliding stability of the synchronizer 3, in some embodiments, a first limiting structure 35 for abutting against one side of the limiting block 34 is provided between the first linkage arm 32 and the second linkage wall of the synchronizer 3, and a second limiting structure 36 for abutting against the other side of the limiting block 34 is provided in the first hollow hole 312. The lateral displacement of the synchronizer 3 during the sliding process can be limited. By adding the first limiting structure 35 and the second limiting structure 36, the design further enhances the stability of the handle structure. It ensures that the synchronizer 3 can remain stable during the sliding process, avoids safety hazards caused by loose structure or abnormal function, helps users to more accurately control the locking or unlocking state, and improves the user experience. In the present embodiment 1, the first limiting structure 35 is a baffle 351, the baffle 351 is vertically connected between the first linkage arm 32 and the second linkage wall, and the total thickness of the limiting block 34 and the sliding block 341 is less than or equal to the distance from the baffle 351 to the surface of the sliding plate 31 on the side facing away from the vertical frame 6, so that the sliding block 341 will not protrude from the first hollow hole 312, thereby ensuring the flatness of the side wall of the sliding door 5 and improving the sealing when closing the door. The second limiting structure 36 is a triangular block 361, the triangular block 361 is in contact with the side of the limiting block 34 facing the first hollow hole 312, so that the limiting block 34 is limited between the baffle 351 and the triangular block 361, and the sliding block 341 is limited in the first hollow hole 312.

[0048] Preferably, the longitudinal height of the first linkage arm 32 and the second linkage arm 33 sliding in the second hollow hole 64 is consistent with the longitudinal height of the sliding block 341 sliding in the first hollow hole 312. This arrangement can help reduce structural friction and resistance caused by height inconsistency, thereby improving sliding efficiency and stability, and can also resist external interference and impact force, thereby ensuring the reliability and safety of the handle structure.

[0049] In some embodiments, the first handle housing 1 and the second handle housing 2 are symmetrically arranged, the first sliding portion 11 and the second sliding portion 21 are both vertically arranged waist-shaped slide grooves, and a third hollow hole 13 is arranged in the waist-shaped slide groove. The first trigger member 12 and the second trigger member 22 are both provided with an operating position 121 extending into the third hollow hole 13, so that the user can conveniently operate the trigger member to open or close the handle structure, thereby improving the convenience and accuracy of the operation. Preferably, the operating position 121 has an operating hole or an operating groove, which can be used to insert a driving member, such as a screwdriver or other tools, and can also be used to insert a handpiece 8 to facilitate user operation. This embodiment is not specifically limited. The handpiece 8 can serve as a handle for the sliding door 5, while taking into account the functions of locking and unlocking.

[0050] In some embodiments without the handpiece 8, it is necessary to provide a push-pull portion 14 on the first handle housing 1 and the second handle housing 2 to facilitate the movement of the sliding door 5, so that the sliding door 5 can be moved by holding the push-pull portion 14 and applying a push or pull force, providing an intuitive and convenient operation method, so that the user can easily move the sliding door 5. Preferably, the shape of the push-pull portion 14 is not specifically limited, and it only needs to be able to facilitate pushing the sliding door 5.

[0051] In some embodiments, in order to improve the sliding stability of the first trigger member 12 and the second trigger member 22, a clamping mechanism 15 is provided at the edge of the first sliding part 11 and the second sliding part 21, and the clamping mechanism 15 is clamped with a limit plate 16, and a space for limiting the sliding of the first trigger member 12 is formed between the limit plate 16 and the first sliding part 11, and a space for limiting the sliding of the second trigger member 22 is formed between the limit plate 16 and the second sliding part 21, and a fourth hollow hole 161 is provided on the limit plate 16, and the first trigger member 12 and the second trigger member 22 are both provided with a clamping position 122 extending from the fourth hollow hole 161, and the clamping position 122 is used to clamp with the synchronous member 3, which can effectively limit the sliding range of the first trigger member 12 and the second trigger member 22, and prevent them from being damaged or failing due to excessive sliding. Stable sliding restriction and linkage functions are provided to ensure the reliability and safety of the handle structure. In the present embodiment 1, the clamping mechanism 15 is a plurality of clamping claws arranged in opposite directions to fix the limit plate 16. The limit plate 16 can be provided with hollow holes to reduce the weight of the limit plate 16 and realize a lightweight design. The first linkage arm 32 and the second linkage wall are provided with a concave U-shaped groove 321 on the side away from the vertical frame 6. The clamping position 122 is horizontally inserted into the U-shaped groove 321. When the first trigger member 12 and the second trigger member 22 drive their respective clamping positions 122 to rise, they can abut against the top surface of the U-shaped groove 321 to drive the synchronous member 3 to move upward synchronously, thereby realizing the locking operation of the locking member 4.

[0052] In order to realize the two states of the first trigger member 12 and the second trigger member 22 sliding, namely, the locked state of sliding to the upper part and the unlocked state of sliding to the lower part, when in the locked state, it is necessary to set a power to overcome the weight of the locking member 4, the synchronous member 3, and the first trigger member 12 and the second trigger member 22 to avoid automatic sliding due to the influence of the hand. This structure is a prior art, so it will not be described in detail. In this embodiment 1, an elastic member 7 is arranged between the limit block 34 and the first limit structure 35. When the synchronous member 3 slides upward, the elastic member 7 is triggered, so that the elastic member 7 provides an upward reset force to offset the weight of the locking member 4, the synchronous member 3, the first trigger member 12 and the second trigger member 22, so that the first trigger member 12 and the second trigger member 22 can be kept in the locked state. When the synchronous member 3 slides downward, the elastic member 7 is not subjected to force or reset, and the locking member 4, the synchronous member 3, the first trigger member 12 and the second trigger member 22 are affected by their own weight and remain in the unlocked state. Preferably, the elastic member 7 is a torsion spring, one end of which is engaged with the protrusion on the limit block 34, and the other end of which is engaged with the protrusion on the first limit structure 35. In other embodiments, the specific structure of the elastic member 7 is not limited, as long as the above-mentioned effect can be achieved, and a locking structure in the prior art can also be used instead, which is not specifically limited in this embodiment.

[0053] In summary, the sliding door handle structure provided by the present invention has the following technical effects:

[0054] 1. The locking and unlocking states of the locking element 4 can be synchronously controlled by operating the respective handle housings both inside and outside the door. This not only maintains the safety of the door under normal circumstances and prevents unauthorized access, but also provides the possibility of opening the door directly from the outside in an emergency, thereby greatly improving convenience and escape efficiency;

[0055] 2. Since the first handle housing 1 and the second handle housing 2 are symmetrically designed and are both connected to the locking member 4 via the synchronizing member 3, their installation positions can be interchanged without affecting the function. This design avoids the problem of position reversal that may occur during installation, simplifies the assembly process, and reduces the difficulty and error rate of installation;

[0056] 3. Since the structures of the first handle housing 1 and the second handle housing 2 are completely identical, they can be produced using the same set of molds. This not only simplifies the production process, but also greatly reduces production costs, realizes standardized production, and improves production efficiency.

[0057] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
