[0015] This part will describe the specific embodiments of the utility model in detail, the preferred embodiments of the utility model are shown in the drawings, the drawings are used to supplement the description of the text part of the specification, so that people can intuitively and visually understand each technical feature and the overall technical scheme of the utility model, but it cannot be understood as the limitation of the protection scope of the utility model.
[0016] Referring to the drawings, Figs. 1-3 The application provides a front panel assembly structure of an intelligent door lock, which comprises a lock shell 1, a handle 2, a handle core 3 and a reversing screw 5, the handle is rotationally connected to the outer side of the lock shell, the handle core 3 is arranged on the inner side of the lock shell 1 and is connected and linked with the handle 2, the lock shell 1 is provided with a first screw hole for connecting the reversing screw on the right side of the handle core, the handle core 3 is provided with a following positioning card 4, the positioning card is provided with a positioning opening 6, the positioning opening can be passed through by the reversing screw 5, when the handle 2 is vertically downward, the positioning opening 6 corresponds to the first screw hole, when the intelligent door lock production enterprise produces the intelligent door lock, the reversing screw is unscrewed, the handle is rotated to the vertical state, the positioning opening is aligned with the first screw hole, then the reversing screw is screwed in again, after the reversing screw is screwed in, the positioning card cannot be rotated because the reversing screw is located on the positioning opening, similarly, the handle cannot be rotated because the handle core and the handle are in the linked state with the positioning card, so that the vertical storage state of the handle is maintained, so as to facilitate packaging and transportation. When the user installs the intelligent door lock, the reversing screw is removed, the handle is rotated to the unfolded use state, then the reversing screw is screwed in again.
[0017] The handle core 3 is provided with a positioning groove 7, the positioning card has a positioning part 8 connected with the positioning groove, the connection and cooperation of the positioning groove and the positioning part can ensure that the positioning card follows when the handle core rotates.
[0018] The handle core 3 is provided with a nut 9 for pressing and positioning a card, and the surface of the handle core is provided with a threaded structure matched with the nut.
[0019] The handle core 3 has a plug-in part 31, the handle 2 has a plug-in cavity connected with the plug-in part, the plug-in part is connected with the plug-in cavity and is fixed by a fixing screw 10, specifically, the handle core is inserted from the inside of the lock shell to the outside, the plug-in part is inserted out of the lock shell, then the handle is aligned with the plug-in part from the outside of the lock shell, the plug-in cavity is connected with the plug-in part, and then the fixing screw is tightened to fix.
[0020] The handle core 3 is sleeved with a reset torsion spring 11, the reset torsion spring is located between the positioning card 4 and the lock shell 1, the reset torsion spring has a first end 111 and a second end 112 extending outward, and the positioning card is provided with a pushing part 12 between the first end and the second end. When the intelligent door lock is installed, the user unscrews the reversing screw, rotates the handle to the unfolded state, the first end and the second end are kept at the upper and lower ends of the first screw hole under the driving of the pushing part of the positioning card, then the reversing screw is screwed in again, the first end and the second end of the reset torsion spring keep the unfolded state of the handle, when the user rotates the handle downward, the first end 111 is blocked by the reversing screw, and the second end 112 is rotated under the driving of the pushing part, so that the reset torsion spring is in a twisted deformation state, when the user releases the handle, the handle is reset to the unfolded state of use under the action of the force of the reset torsion spring.
[0021] The lock shell 1 located on the left side of the handle core is provided with a second screw hole 13 for connecting the reversing screw, the reversing screw can be installed in the first screw hole or the second screw hole, so that the user can select the opening direction of the handle according to the use requirement.
