[0037] In view of the problems existing in the traditional emergency unlocking structure in the prior art mentioned above, the utility model proposes a handle assembly.

[0038] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] In this embodiment, a handle assembly is disclosed. Figure 1 The entire three-dimensional structure of the handle assembly is shown. Figure 2 The three-dimensional cross-sectional structure of the handle assembly involved in the handle assembly is shown. Figure 3 The entire three-dimensional structure of a handle assembly in another embodiment is shown. Figure 4 The three-dimensional cross-sectional structure of a handle assembly involved in another embodiment is shown. Figure 5 To show the entire three-dimensional structure of the unlocking cam involved in the handle assembly. Figure 6 The entire three-dimensional structure of the unlocking cam involved in the handle assembly in another embodiment is shown.

[0040] Generally speaking, the outer handle 1 is rotatably connected to the lock through the square core 6 when in use. Rotating the outer handle 1 can retract the lock tongue of the lock through the square core 6 to achieve a normal unlocking function. However, when the lock is in the reverse lock state, the outer handle 1 is usually restricted in rotation, or even if the outer handle 1 is rotated, it cannot drive the reverse lock mechanism of the lock to rotate, nor can it retract the reverse lock tongue. Therefore, in order to be able to release the reverse lock on the outer handle 1 in an emergency, especially on a keyless door lock, an emergency unlocking structure is provided.

[0041] Among them, one end of the unlocking cam 2 is connected to the anti-locking mechanism of the lock when in use. For example, in one embodiment, an unlocking strip 4 can be inserted into the unlocking cam 2 along the axial direction, and the other end of the unlocking strip 4 is connected to the anti-locking mechanism of the lock when in use. When the unlocking cam 2 rotates, it can synchronously drive the unlocking strip 4 to rotate around the axial direction, thereby rotating and unlocking the anti-locking mechanism. By providing the unlocking strip 4, the length of the unlocking cam 2 can be extended, which is convenient for assembling various parts in the lock. In other embodiments, one end of the unlocking cam 2 can also be directly extended to be directly connected to the anti-locking mechanism of the lock, which can also achieve the purpose of unlocking.

[0042] Please refer to Figures 1 to 6The handle assembly of the utility model includes: an outer handle 1, an unlocking hole 3 arranged on the outer handle 1, and an unlocking cam 2 arranged in the outer handle 1; the outer handle 1 includes a shaft neck 11 and a gripping portion 12, wherein the unlocking hole 3 is arranged through the side wall of the shaft neck 11; the unlocking cam 2 is rotatably arranged in the shaft neck 11, and at least one toggle portion opposite to the unlocking hole 3 is arranged on the surface of the unlocking cam 2, and one end of the unlocking cam 2 is connected to the anti-locking mechanism of the lock when in use. In this embodiment, when emergency unlocking is required, the user only needs to select any rod that can be smoothly inserted into the unlocking hole 3, gently abut against the toggle portion, and apply appropriate force to one side, so that the unlocking cam 2 can be easily rotated, and the rotation of the unlocking cam 2 can not only further link the unlocking bar 4 to rotate, thereby driving the anti-locking mechanism to unlock, so as to quickly complete the emergency unlocking. Such a design not only simplifies the steps of emergency unlocking, but also greatly improves the emergency unlocking efficiency of the user in an emergency. Hiding the emergency unlocking structure in the neck portion 11 not only does not cause any visual interference to the front visible surface of the external handle 1, thus maintaining the overall aesthetics of the door lock, but also ensures the practicality of the function and the convenience of operation. Even in low light or tense conditions, users can quickly find the emergency unlocking structure and easily achieve emergency unlocking.

[0043] Among them, Figure 1 As shown, the unlocking hole 3 is a strip hole, which is not only convenient for users to insert tools to unlock, but also convenient for guiding users to move the rod for emergency unlocking along the length direction of the strip hole, and also increases the flexibility and reliability of unlocking. Figure 3 As shown, in another embodiment, the unlocking hole 3 is a round hole, and it is only necessary to ensure that a toggle portion can be completely exposed in the unlocking hole 3 so that the user can smoothly abut the rod body against the toggle portion and successfully toggle the toggle portion.

[0044] The unlocking hole 3 is perpendicular to the axial direction of the shaft neck 11 , and when the user performs an emergency unlocking operation, a large force is not required to push the unlocking cam 2 to rotate.

[0045] The toggle portion is arranged around the surface of the unlocking cam 2 to ensure that no matter from which angle the user operates the handle, it can cooperate with the toggle portion smoothly to achieve unlocking.

[0046] Among them, Figure 4As shown, in a specific embodiment, the toggle portion is a toggle hole 21 opened on the side wall of the unlocking cam 2, wherein the diameter of the toggle hole 21 is smaller than the maximum width of the unlocking hole 3, ensuring that the toggle hole 21 can be exposed in the unlocking hole 3, so that the user can better insert the rod into the toggle hole 21. When the rod is extended into the unlocking hole 3 and abuts against the toggle hole 21, the toggle hole 21 can better clamp the rod, so that the rod will not shake easily during the toggle process, and the operation process is more stable.

[0047] Among them, Figure 5 As shown, in another specific embodiment, the toggle portion is a toggle piece 22 disposed on the side wall of the unlocking cam 2, wherein the thickness of the toggle piece 22 is less than the minimum length of the unlocking hole 3, in order to ensure that there is a gap between the toggle piece 22 and the unlocking hole 3 for the rod to be inserted. In a specific embodiment, the thickness of the toggle piece 22 can be adjusted according to specific needs, and when the unlocking cam 2 needs to rotate clockwise, the rod is abutted against the upper surface of the toggle piece and moves downward; when the unlocking cam 2 needs to rotate counterclockwise, the rod is abutted against the lower surface of the toggle piece and moves upward.

[0048] Among them, the unlocking cam 2 is a tubular structure, which not only reduces the weight and improves the strength, but also makes the internal mechanical structure more compact, thereby improving the performance of the entire lock.

[0049] Among them, after the unlocking cam 2 is assembled in the shaft neck 11, only one or one of the toggle parts is opposite to the unlocking hole 3, and the toggle part can abut against the rod during emergency unlocking, driving the anti-locking mechanism of the lock to rotate and realize unlocking.

[0050] Among them, the outer handle 1 is L-shaped, and the unlocking hole 3 is arranged at the rear side of the grip portion 12. The L-shaped design of the outer handle 1 not only makes the grip portion 12 more ergonomic and improves the comfort of grip, but also enables the unlocking hole 3 to be arranged at the rear side of the grip portion 12, further improving the convenience of operation.

[0051] In order to achieve the above-mentioned purpose, in a second aspect, the utility model provides a door lock, comprising: a lock body structure; an inner handle, rotatably arranged on a side of the lock body structure away from the outer handle 1; a handle assembly as described in any of the above items; wherein an anti-locking mechanism linked to the anti-locking bolt is provided in the lock body structure or the inner handle, and one end of the unlocking cam 2 is connected to the anti-locking mechanism.

[0052] In addition, in this embodiment, a door lock is also disclosed, including a lock body structure, an inner handle and the handle assembly described above. The inner handle is rotatably arranged on a side of the lock body structure away from the outer handle 1. An anti-locking mechanism linked to the anti-locking bolt is arranged in the lock body structure or in the inner handle, and one end of the unlocking cam 2 is connected to the anti-locking mechanism. When the user pushes the unlocking cam 2 to rotate through the unlocking hole 3, the anti-locking structure can be driven to rotate, and then the anti-locking bolt is retracted into the lock body structure to achieve emergency unlocking.

[0053] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
