Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of unlocking piece, especially to a handle structure with emergency unlocking piece. BACKGROUND

[0002] In modern architectural design, sliding doors are widely used in various places such as homes, offices and shopping malls due to their space-saving, elegant and other advantages. In order to ensure the safety of sliding doors, locking structures are usually provided on the door body to prevent unauthorized access or ensure the privacy of the indoor environment. These locking structures often need specific unlocking pieces to realize the unlocking and locking actions to meet the daily use requirements.

[0003] Many existing unlocking pieces need to use professional tools during installation and disassembly, which not only increases the complexity of operation, but also may cause the user to fail to quickly complete the installation or disassembly of the unlocking piece in an emergency. In addition, the cumbersome installation steps may also affect the appearance and service life of the door body. Moreover, the unlocking pieces in the prior art often have complex structures and large volumes, which makes them need additional manpower and cost during production, packaging and transportation. This not only increases the burden of manufacturers, but also may affect the market competitiveness of products. SUMMARY

[0004] In order to overcome at least one of the defects of the prior art described above, the utility model provides a handle structure with emergency unlocking piece. The problems of difficult disassembly and inconvenient installation of the unlocking piece can be solved.

[0005] The technical scheme adopted by the utility model to solve the problem is:

[0006] A handle structure with emergency unlocking piece, comprising: an outer handle, the outer handle is used for assembling to one side of a door body; an inner handle, the inner handle is used for assembling to the other side of the door body; at least one unlocking piece body, the unlocking piece body has a connecting end, which is used for mounting to the outer handle and / or inner handle; the outer handle and the inner handle are both provided with a connecting hole for assembling the connecting end, and the connecting end and the connecting hole are detachably connected.

[0007] By adopting the above scheme, the unlocking part body can be selectively installed on the outer handle or the inner handle, or even on both at the same time according to needs. This design provides greater flexibility and meets the use requirements in different scenarios. When the unlocking part body is not installed, the connecting hole is hidden or difficult to access, thereby avoiding the risk that anyone can perform illegal operations through the connecting hole. This greatly improves the security of the door body. Once the unlocking part body is installed, it can serve as a hand-held part, facilitating the user to perform unlocking operations through the connecting hole. This design not only simplifies the operation process, but also improves the convenience of operation. The detachable connection between the unlocking part body and the handle makes the disassembly process simple and fast. The disassembled unlocking part body is easy to transport and store, greatly saving space. In an emergency, the user can quickly install or disassemble the unlocking part body to meet different security requirements. This design improves the response speed and security of the door body in an emergency.

[0008] Further, the outer handle and the inner handle are symmetrically arranged, and each comprises a hand-holding part and an unlocking part, the unlocking part is provided with a sliding groove, a sliding part for driving the locking bolt to be locked is slidably arranged in the sliding groove, and the connecting hole is arranged on the sliding part and does not protrude from the sliding groove.

[0009] By adopting the above scheme, since the connecting hole on the sliding part does not protrude from the sliding groove, this design effectively hides the connecting hole, avoiding unauthorized personnel from performing illegal operations through the connecting hole. When the unlocking part body is not installed, the connecting hole is completely blocked, increasing the security of the door body. The design of the sliding groove and the sliding part makes the user's operation more explicit and accurate, reducing the security risks caused by misoperation.

[0010] Further, the unlocking part body further comprises an operation end, the operation end is connected with the connecting end, and the operation end is exposed outside the connecting hole.

[0011] By adopting the above scheme, the user can directly perform unlocking or locking operations through the operation end without the need for other tools or complex actions. This design simplifies the operation process and improves the convenience of operation. The protruding design of the operation end enables the user to quickly identify and locate the operation position of the unlocking part body, avoiding wasting time and effort in searching for the operation position.

[0012] Further, the connecting end and the operation end are integrally formed.

[0013] By adopting the above scheme, the integrally formed connecting end and operating end form a whole structure, which is more stable under stress than a split design and is less likely to loosen or deform; since no additional connecting member or connecting method is needed between the connecting end and the operating end, the resulting malfunction caused by loosening, damage or improper connection of the connecting member is avoided; the integrally formed design simplifies the production process, reduces the assembly steps and quality control points in the production process, thereby improving the production efficiency, and the simplification of the production process helps to reduce the production cost, including material cost, labor cost and time cost. At the same time, since the assembly link is reduced, the scrap rate caused by improper assembly is also reduced.

[0014] Further, a gap is reserved between the unlocking part on the outer handle and the inner handle and the operating end of the unlocking member body.

[0015] By adopting the above scheme, the reserved gap ensures that the operating end can move smoothly during operation without being interfered by other parts of the handle. This improves the smoothness and flexibility of operation, and the existence of the gap allows users to exert different degrees of force during operation without causing the operating end to jam or be damaged. This is particularly important for users of different ages and strengths. Reducing the direct contact area between the operating end and the handle reduces wear caused by friction. This helps to prolong the service life of the unlocking member body and the handle.

[0016] Further, the operating end and the connecting end are both cylindrical, and the cross-sectional radius of the operating end is greater than or equal to the cross-sectional radius of the connecting end.

[0017] By adopting the above scheme, the operating end has a larger cross-sectional radius, making it easier for users to hold and operate, reducing the risk of misoperation or difficulty in operation due to inconvenience in operation. The larger operating end provides a better feel, allowing users to more clearly perceive the position and movement status of the operating end during operation; the larger cross-sectional radius of the operating end means that it can withstand greater force, which helps to enhance the overall structural strength of the unlocking member body. Compared to the connecting end with a smaller cross-sectional radius, the larger cross-sectional radius of the operating end helps to disperse stress and reduce the risk of damage caused by stress concentration.

[0018] Further, an operating hole is arranged on the side of the operating end away from the connecting end.

[0019] By adopting the above scheme, the arrangement of the operating hole allows users to directly operate the unlocking member body by inserting a tool, improving the ease of installation.

[0020] Further, the operating hole is one of a slot hole, a cross hole, a square hole, a herringbone hole, a hexagonal hole and a plum blossom hole.

[0021] By adopting the above scheme, the difficulty of cracking the lock by unauthorized personnel can be increased, thereby improving the security, and specific hole type design can prevent ordinary users from misusing inappropriate tools for operation, reducing damage or security risks caused by misoperation.

[0022] In summary, the handle structure with an emergency unlocking member provided by the present utility model has the following technical effects:

[0023] 1. The detachable connection design of the unlocking member body allows the unlocking member body to be conveniently installed on the outer handle or the inner handle, or even on both at the same time according to needs. This design greatly simplifies the installation and disassembly operation process and reduces the operation difficulty. Compared with many unlocking members in the prior art, the unlocking member body of the handle structure does not need to use professional tools during installation and disassembly, thereby avoiding installation difficulties caused by insufficient tools or improper operation;

[0024] 2. When the unlocking member body is not installed, the connecting hole is hidden or difficult to access, which avoids the risk of illegal operation by anyone through the connecting hole and greatly improves the security of the door body. In an emergency, the user can quickly install or disassemble the unlocking member body to meet different security needs. This design improves the response speed of the door body in an emergency and helps to ensure personnel safety;

[0025] 3. Once the unlocking member body is installed, it can serve as a hand-held member to facilitate the user to perform unlocking operation through the connecting hole. This design not only simplifies the operation process but also improves the convenience of operation. The unlocking member body can be selectively installed on the outer handle or the inner handle, or even on both at the same time according to needs.
