Description

TECHNICAL FIELD

[0001] The utility model relates to sliding door accessory technology field especially relates to a sliding door handle structure. BACKGROUND

[0002] With the continuous progress of modern architectural design and the increasing enhancement of people's safety consciousness, as a commonly used component connecting indoor and outdoor, the safety and convenience of sliding door become the focus of consumers. The traditional sliding door handle design is mostly limited to the two sides of the door body, usually only the inside of the door is configured with an unlocking mechanism, and the outside does not have the function of direct opening. Such design improves the safety to a certain extent, but also brings inconvenience in use.

[0003] In addition, the existing sliding door handle structure also has some limitations in 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, and there is a problem of installation position reversal. And due to the difference of handle structure, the mold needs to be opened separately for the inside and outside handle structure during production, which increases the production cost. SUMMARY

[0004] In order to overcome at least one of the defects of the prior art, the utility model provides a sliding door handle structure. The unlocking problem can be solved, and the assembly is simplified to avoid the installation inversion problem.

[0005] The utility model adopts the technical scheme that:

[0006] A sliding door handle structure, comprising: a first handle shell, the first handle shell is assembled on one side of the sliding door, a first sliding part is arranged on the first handle shell in the vertical direction, and a first trigger is slidably arranged on the first sliding part; a second handle shell, the second handle shell is mirror-symmetrical with the first handle shell on both sides of the sliding door, the second handle shell is assembled on the other side of the sliding door, a second sliding part is arranged on the second handle shell in the vertical direction, the second sliding part is mirror-symmetrical with the first sliding part on both sides of the sliding door, a second trigger is slidably arranged on the second sliding part, and the second trigger is mirror-symmetrical with the first trigger on both sides of the sliding door; a synchronization piece, the synchronization piece slides along the longitudinal wall of the sliding door, the synchronization piece moves synchronously with the first trigger and the second trigger, and the part of the synchronization piece connected with the first trigger and the part of the synchronization piece connected with the second trigger are mutually symmetrical; a locking piece, the locking piece is connected above the synchronization piece and is used for locking with the track or door frame above the sliding door; wherein the first handle shell, the second handle shell and the synchronization piece are divided into upper half and lower half with the middle line of the horizontal direction of the synchronization piece as the reference, and the upper half and the lower half are mutually symmetrical.

[0007] By adopting the above scheme, by designing the synchronization part and the locking part, the locking and unlocking states of the locking part 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 directly opening from the outside in an emergency, thereby improving convenience and escape efficiency. Since the first handle housing and the second handle housing are symmetrical in design and are connected to the locking part through the synchronization part, their installation positions can be interchanged without affecting the function, which avoids the problem of reversed installation positions. At the same time, since the first handle housing and the second handle housing are structurally identical, the same mold can be used for production, greatly reducing production costs and achieving standardized production.

[0008] Further, the synchronization part and the sliding door are further provided with a vertical frame, the vertical frame is assembled to the side wall of the sliding door, and the side of the vertical frame away from the sliding door is provided with a vertical track, and the synchronization part is slidably arranged on the vertical track.

[0009] By adopting the above scheme, the vertical frame is assembled to the side wall of the sliding door, providing a stable support structure for the synchronization part, which can effectively prevent the synchronization part from deviating or shaking during sliding, thereby improving the stability and reliability of the entire handle structure.

[0010] Further, the synchronization part comprises a sliding plate, the sliding plate is slidably arranged on the vertical track, a first linkage arm, one end of the first linkage arm is connected to the sliding plate, and the other end penetrates through the vertical frame and is connected to the first trigger part, and a second linkage arm, one end of the second linkage arm is connected to the sliding plate, and the other end penetrates through the vertical frame and is connected to the second trigger part.

[0011] By adopting the above scheme, the sliding plate is responsible for sliding on the vertical track, thereby realizing longitudinal movement, the first linkage arm and the second linkage arm are respectively connected to the sliding plate and the first trigger part and the second trigger part, realizing mechanical linkage between them. When one side of the trigger part 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 other side of the trigger part to move synchronously through the other side of the linkage arm.

[0012] Further, the sliding plate is centrally provided with a first hollow hole, the vertical frame is provided with a second hollow hole, the second hollow hole is provided with a limiting block, and the limiting 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 scheme, the second hollow hole arranged on the vertical frame provides an installation space for the limiting block, and 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 rail, ensuring that the sliding plate can stop sliding when reaching the predetermined position, and avoiding structural damage or functional failure caused by excessive sliding.

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

[0015] By adopting the above scheme, the transverse deviation of the synchronization piece during sliding is limited, and by adding the first limiting structure and the second limiting structure, the stability of the handle structure is further enhanced. It ensures that the synchronization piece can remain stable during sliding, avoids potential safety hazards caused by structural looseness or functional abnormalities, and helps users more accurately control the locking or unlocking state, improving the user experience.

[0016] Further, the synchronization piece is centrally symmetric with respect to the midpoint of the first hollow hole.

[0017] By adopting the above scheme, even if the synchronization piece is integrated with the first handle shell and the second handle shell, it can still be assembled with the sliding door after being reversed as a whole, without the need to pay special attention to the installation order and whether the inside and outside handles are installed reversely.

[0018] Further, the side of the vertical frame facing the sliding door is provided with an assembly groove for clamping with the sliding door, and the assembly groove is provided with a clearance 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 simultaneously after being assembled with the sliding door.

[0019] By adopting the above scheme, by inserting the handle shell into the assembly groove, quick and stable connection can be achieved, reducing the complexity and time cost in the installation process; the clamping mode 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 clearance groove ensures that the first handle shell and the second handle shell can be smoothly inserted into the assembly groove during assembly. The shape and size of the clearance groove match the outer shape of the handle shell, avoiding installation difficulties or damage caused by size mismatch. It can also ensure that the handle shell remains flat and beautiful after installation with the surface of the sliding door. It helps to improve the visual effect and user experience of the entire door and window product

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

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

[0022] Further, the edges of the first sliding part and the second sliding part are both provided with a clamping mechanism, the clamping mechanism clamps a limiting plate, a space for limiting the sliding of the first trigger is formed between the limiting plate and the first sliding part, a space for limiting the sliding of the second trigger is formed between the limiting plate and the second sliding part, a fourth hollow hole is arranged on the limiting plate, and the first trigger and the second trigger are both provided with a clamping position extending out of the fourth hollow hole, and the clamping position is used for clamping the synchronous member.

[0023] By using the above scheme, the sliding range of the first trigger and the second trigger can be effectively limited to prevent damage or failure due to excessive sliding. Stable sliding limitation and linkage function are provided to ensure the reliability and safety of the handle structure

[0024] Further, the first handle shell and the second handle shell are provided with a push-pull part for facilitating the movement of the sliding door.

[0025] By using the above scheme, the sliding door can be moved by holding the push-pull part and applying a pushing force or a pulling force, and an intuitive and convenient operation mode is provided, so that the user can easily move the sliding door.

[0026] In summary, the push-pull door handle structure has the following technical effects:

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

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

[0029] 3. Since the first handle housing and the second handle housing are completely identical in structure, it means that they can be produced by the same set of molds. This not only simplifies the production process, but also greatly reduces the production cost, realizes standardized production, and improves the production efficiency. BRIEF DESCRIPTION OF DRAWINGS

Obviously, only a part of the examples of the utility model are described here, and not all the examples. Based on the embodiments in the utility model, all other examples obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0038] In order to facilitate the understanding of the embodiments of the present application, the following will be further explained and described with specific examples combined with the drawings, and each embodiment does not constitute a limitation on the embodiments of the present application.

[0039] In the description of the present application, it should be pointed out that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore cannot be understood as a limitation on the present application.

[0040] 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 the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application.

[0041] Embodiment 1 of the present application refers to Figures 1-6As shown, a push-pull door handle structure is disclosed, comprising a first handle housing 1, a second handle housing 2, a synchronization piece 3 and a locking piece 4. The first handle housing 1 is assembled on one side of the push-pull door 5, and a first sliding part 11 is arranged on the first handle housing 1 in the vertical direction. The first sliding part 11 is slidably provided with a first trigger piece 12. The second handle housing 2 is assembled on the other side of the push-pull door 5, and a second sliding part 21 is arranged on the second handle housing 2 in the vertical direction. The second sliding part 21 is slidably provided with a second trigger piece 22. In order to reduce production costs, first, the second handle housing 2 is mirror-symmetrical with the first handle housing 1 on both sides of the push-pull door 5. The first handle housing 1 and the second handle housing 2 are mirror-symmetrical on both sides of the push-pull door 5, and the structures of the two are symmetrical and identical. The ingenuity of this design is that it allows the same mold to be used for mass production, thereby greatly reducing production costs. The sharing of mold costs significantly reduces the production cost of each component. At the same time, standardized production processes also improve production efficiency, as workers can quickly master and efficiently complete the production of the same component, reducing the time spent on training and familiarizing themselves with new molds. Secondly, the second sliding part 21 and the first sliding part 11 are mirror-symmetrical on both sides of the push-pull door 5. The second trigger piece 22 and the first trigger piece 12 are mirror-symmetrical on both sides of the push-pull door 5, so that the first trigger piece 12 and the second trigger piece 22 can be seamlessly assembled with the synchronization piece 3 and move synchronously regardless of which side of the handle housing they are installed on. This feature greatly reduces installation difficulty and improves installation flexibility and accuracy. At the same time, since the connection parts of the synchronization piece 3 and the two trigger pieces are symmetrical to each other, there is no need to worry about the installation order or the distinction between the inside and outside door handles, further simplifying the installation process and improving installation efficiency. The synchronization piece 3 slides longitudinally along the side wall of the push-pull door 5. The synchronization piece 3 moves synchronously with the first trigger piece 12 and the second trigger piece 22. The parts of the synchronization piece 3 connected to the first trigger piece 12 and the second trigger piece 22 are symmetrical to each other, so that the first trigger piece 12 and the second trigger piece 22 can be assembled with the synchronization piece 3 and move synchronously regardless of whether they are installed on the first handle housing 1 or the second handle housing 2 during the installation process, greatly reducing installation difficulty. The locking piece 4 is connected above the synchronization piece 3 and is used to lock with the track or door frame above the push-pull door 5, so that the inside and outside of the door can be synchronized to control the locking and unlocking states of the locking piece 4 by operating the respective handle housings. This design ensures the safety of the door under normal circumstances and provides the possibility of opening directly from the outside in emergency situations, thereby improving convenience and escape efficiency. This dual protection design achieves a perfect balance between safety and convenience for the handle structure.Finally, the first handle housing 1, the second handle housing 2 and the synchronization piece 3 are divided into upper and lower halves based on the plane where the midline of the horizontal direction of the synchronization piece 3 is located, and the upper and lower halves are symmetrical to each other. Due to the symmetrical feature of the upper and lower halves, the two can still be assembled to the two sides of the folding door after being interchanged, without considering the installation sequence of the two handles, without distinguishing the handles of the inner and outer doors, improving the installation efficiency and avoiding the problem of misassembly. Through the design of the synchronization piece 3 and the locking piece 4, the door inside and outside can be synchronized to control the locking and unlocking state of the locking piece 4 by operating the respective handle housings, which not only maintains the safety of the door under normal circumstances, but also provides the possibility of directly opening 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 symmetrical in design and are connected to the locking piece 4 through the synchronization piece 3, their installation positions can be interchanged without affecting the function, which avoids the problem of reversed installation positions.

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

[0043] Generally, the edges of the sliding door 5 are provided with door frames, so in some embodiments, a vertical frame 6 is provided between the synchronization piece 3 and the sliding door 5, which is assembled to the side wall of the sliding door 5, and the vertical frame 6 is provided with a vertical track 61 away from one side of the sliding door 5, and the synchronization piece 3 is slidably arranged on the vertical track 61. The vertical frame 6 is assembled to the side wall of the sliding door 5, which provides a stable support structure for the synchronization piece 3, effectively preventing the synchronization piece 3 from shifting or shaking during sliding, thereby improving the stability and reliability of the entire handle structure. Specifically, the vertical frame 6 is provided with an assembly groove 62 on the side facing the sliding door 5, which is used for clamping with the sliding door 5, and the assembly groove 62 is provided with a relief groove 63 corresponding to the first handle shell 1 and the second handle shell 2, so that the first handle shell 1 and the second handle shell 2 can be inserted into the assembly groove 62 after being assembled with the sliding door 5. By inserting the handle shell into the assembly groove 62, quick and stable connection can be achieved, reducing the complexity and time cost of the installation process; the clamping mode between the assembly 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 relief groove 63 ensures that the first handle shell 1 and the second handle shell 2 can be smoothly inserted into the assembly groove 62 during assembly. The shape and size of the relief groove 63 match the shape of the handle shell, avoiding installation difficulties or damage due to size incompatibility. It can also ensure that the handle shell remains flat and beautiful after installation with the surface of the sliding door 5. It helps to improve the visual effect and user experience of the entire door and window product.

[0044] Due to the ingenious design of the avoidance groove 63, this innovative feature makes the sliding door handle structure exhibit high flexibility and adaptability. Specifically, regardless of the structure of the vertical frame 6 changing with the design requirements of different sliding doors 5, it can be seamlessly inserted with one end of the first handle shell 1 and the second handle shell 2. This design not only ensures the speed of installation, but also greatly improves the stability of installation, making the entire installation process efficient and reliable. More importantly, the existence of the avoidance groove 63 eliminates the assembly differences that may be caused by the change of the structure of the vertical frame 6. This means that regardless of the adjustment of the structure of the sliding door 5 or the vertical frame 6, the handle structure can perfectly adapt without additional modification or adjustment. This design makes the product widely applicable to various types of sliding doors, thereby greatly improving the universality 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 traditional handle structures in terms of adaptability. It not only easily meets the diversified needs of sliding doors and vertical frames, but also provides users with a more convenient and efficient installation experience. This design not only reflects the pursuit of product details, but also fully demonstrates the excellent ability in technological innovation.

[0045] In order to facilitate the synchronous movement of the synchronization piece 3 with the first trigger piece 12 and the second trigger piece 22, a second hollow hole 64 is provided on the vertical frame 6, and the synchronization piece 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, and the edge of the sliding plate 31 is provided with a clamping edge 311 for clamping with the track. In this embodiment 1, the structure between the vertical track 61 and the clamping edge 311 is L-shaped, and in other embodiments, the specific shape of the two is not limited as long as they can be adapted for clamping. The central part of the sliding plate 31 is provided with a first hollow hole 312, and the synchronization piece 3 is symmetrically centered with the midpoint of the first hollow hole 312 as the reference center. By this arrangement, even if the synchronization piece 3 is integrated and installed with the first handle shell 1 and the second handle shell 2, it can still be assembled with the sliding door 5 after the whole is reversed, without the need to pay special attention to the installation order and the problem of whether the inside and outside handles are installed reversely.

[0046] The second hollow hole 64 is provided with a limiting block 34, preferably, the limiting block 34 is provided with a clamping edge 311 at the upper and lower ends, and the clamping edge 311 is clamped and fixed with the top and bottom of the second hollow hole 64. The limiting block 34 is provided with a sliding block 341 extending into the first hollow hole 312, so as to limit the longitudinal sliding distance of the sliding plate 31 along the vertical rail 61. The second hollow hole 64 provided on the vertical frame 6 provides a mounting space for the limiting block 34, and the sliding block 341 can be in contact with the edge of the first hollow hole 312 during the sliding process of the sliding plate 31, so as to limit the longitudinal sliding distance of the sliding plate 31 along the vertical rail 61, and ensure that the sliding plate 31 can stop sliding when reaching the predetermined position, avoiding structural damage or functional failure caused by excessive sliding. One end of the first linkage arm 32 is connected with the sliding plate 31, and the other end penetrates through the vertical frame 6 and is clamped with the first trigger 12. One end of the second linkage arm 33 is connected with the sliding plate 31, and the other end penetrates through the vertical frame 6 and is clamped with the second trigger 22. The sliding plate 31 is responsible for sliding on the vertical rail 61, so as to realize longitudinal movement. The first linkage arm 32 and the second linkage arm 33 are respectively connected with the sliding plate 31, the first trigger 12 and the second trigger 22, so as to realize mechanical linkage between them. When one side of the trigger is operated, it will push or pull the sliding plate 31 to slide on the vertical rail 61 through the corresponding linkage arm, and then drive the trigger 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 arm are symmetrically and parallelly arranged, and the interval distance between the first linkage arm 32 and the second linkage arm is less than or equal to the transverse distance of the second hollow hole 64. And the limiting block 34 still reserves a space for the first linkage arm 32 and the second linkage arm to penetrate after being installed into the second hollow hole 64.

[0047] To improve the longitudinal sliding stability of the synchronization piece 3, in some embodiments, a first limiting structure 35 is arranged between the first linkage arm 32 and the second linkage wall of the synchronization piece 3 for abutting against one side of the limiting block 34, and a second limiting structure 36 is arranged in the first hollow hole 312 for abutting against the other side of the limiting block 34. The transverse deviation of the synchronization piece 3 during sliding can be limited, and the stability of the handle structure is further enhanced by increasing the first limiting structure 35 and the second limiting structure 36. It ensures that the synchronization piece 3 can remain stable during sliding, avoids safety hazards caused by loose structure or abnormal function, helps users to more accurately control the locking or unlocking state, and improves the use experience. In this embodiment 1, the first limiting structure 35 is a baffle 351 which 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 away from the vertical frame 6, so that the sliding block 341 does not protrude out of the first hollow hole 312, thereby ensuring the flatness of the side wall of the sliding door 5 and improving the sealing performance when closing the door. The second limiting structure 36 is a triangular block 361 which abuts against 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. By this arrangement, it can help to reduce the structural friction and resistance caused by inconsistent height, thereby improving the sliding efficiency and stability, and also being able to 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 arranged symmetrically, the first sliding part 11 and the second sliding part 21 are both vertically arranged waist-shaped sliding grooves, the waist-shaped sliding grooves are provided with third hollow holes 13, and the first trigger 12 and the second trigger 22 are both provided with operation positions 121 which extend into the third hollow holes 13, so that users can conveniently operate the triggers to open or close the handle structure, thereby improving the convenience and accuracy of operation. Preferably, the operation position 121 has an operation hole or an operation slot which can be used for inserting a driving member such as a screwdriver or other tools, or a handheld member 8 for facilitating user operation. This embodiment is not limited in particular. The handheld member 8 can serve as a handle of the sliding door 5 while also serving the functions of locking and unlocking.

[0050] In some embodiments without the handpiece 8, it is necessary to provide a pushing and pulling part 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 pushing and pulling part 14 and applying a pushing or pulling force, providing an intuitive and convenient operation mode, so that the user can easily move the sliding door 5. Preferably, the shape of the pushing and pulling part 14 is not limited, and it can be convenient to push the sliding door 5.

[0051] In some embodiments, in order to improve the sliding stability of the first trigger 12 and the second trigger 22, a clamping mechanism 15 is arranged on the edge of the first sliding part 11 and the second sliding part 21, the clamping mechanism 15 clamps a limiting plate 16, the limiting plate 16 and the first sliding part 11 form a space for limiting the sliding of the first trigger 12, the limiting plate 16 and the second sliding part 21 form a space for limiting the sliding of the second trigger 22, the limiting plate 16 is provided with a fourth hollow hole 161, the first trigger 12 and the second trigger 22 are provided with a clamping position 122 extending out of the fourth hollow hole 161, the clamping position 122 is used for clamping with the synchronization piece 3, which can effectively limit the sliding range of the first trigger 12 and the second trigger 22, and prevent them from being damaged or failed due to excessive sliding. It provides stable sliding limitation and linkage function, and ensures the reliability and safety of the handle structure. In this embodiment 1, the clamping mechanism 15 is a plurality of oppositely arranged clamping claws for fixing the limiting plate 16, and the limiting plate 16 can be additionally provided with a hollow hole to reduce the weight of the limiting plate 16 and realize lightweight design. The first linkage arm 32 and the second linkage wall are provided with a concave U-shaped groove 321 away from one side of the vertical frame 6, the clamping position 122 is horizontally inserted into the U-shaped groove 321, when the first trigger 12 and the second trigger 22 drive the respective clamping positions 122 to rise, it can abut against the top surface of the U-shaped groove 321 to drive the synchronization piece 3 to move upward synchronously, thereby realizing the locking operation of the locking piece 4.

[0052] In order to realize the two states of sliding of the first trigger 12 and the second trigger 22, i.e. the locked state of sliding to the upper side and the unlocked state of sliding to the lower side, when in the locked state, a power overcoming the weight of the upper locking piece 4, the synchronization piece 3 and the first trigger 12 and the second trigger 22 is required to avoid the automatic sliding caused by the hand influence. The structure is the prior art, and thus will not be described in detail. In the embodiment 1, the elastic piece 7 is arranged between the limiting block 34 and the first limiting structure 35, and the elastic piece 7 is triggered when the synchronization piece 3 slides upward, so that the elastic piece 7 provides an upward reset force to offset the weight of the upper locking piece 4, the synchronization piece 3 and the first trigger 12 and the second trigger 22, so that the first trigger 12 and the second trigger 22 can be kept in the locked state, and when the synchronization piece 3 slides downward, the elastic piece 7 is not stressed or reset, and the upper locking piece 4, the synchronization piece 3 and the first trigger 12 and the second trigger 22 are kept in the unlocked state due to the influence of the weight. Preferably, the elastic piece 7 is a torsion spring, one end of the torsion spring is clamped with the protrusion on the limiting block 34, and the other end of the torsion spring is clamped with the protrusion on the first limiting structure 35. In other embodiments, the specific structure of the elastic piece 7 is not limited, as long as the above-mentioned effect can be realized, and the existing technology can be used instead, and the embodiment is not limited in detail.

[0053] In summary, the push-pull door handle structure has the following technical effects:

[0054] 1. The door inside and outside can be controlled by operating the respective handle shell to synchronize the locking and unlocking state of the upper locking piece 4. This not only maintains the safety of the door under normal circumstances to prevent unauthorized access, but also provides the possibility of opening directly from the outside in an emergency, thereby greatly improving the convenience and escape efficiency;

[0055] 2. Since the first handle shell 1 and the second handle shell 2 are symmetrical in design and are connected to the upper locking piece 4 through the synchronization piece 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 installation difficulty and error rate;

[0056] 3. Since the first handle shell 1 and the second handle shell 2 have the same structure, it means that they can be produced with the same mold. This not only simplifies the production process, but also greatly reduces the production cost, realizes standardized production, and improves the production efficiency.

[0057] The technical means disclosed by the utility model scheme are not limited to the technical means disclosed by the above-mentioned embodiments, and also include technical schemes composed of any combination of the above technical features. It should be noted that, for ordinary skilled persons in the art, without departing from the principles of the utility model, a number of improvements and refinements can be made, and these improvements and refinements are also considered within the protection scope of the utility model.
