[0019] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:
[0020] like Figures 1 to 5The embodiment of the utility model shown preferably provides a split handle structure of a smart door lock, including a lock body 1 and a handle 2, wherein a transmission member 3 is rotatably arranged in the lock body 1, one end of the transmission member 3 protrudes outwardly from the outside of the lock body 1 and is provided with a transmission block 4, the other end of the transmission member 3 is located on the inner side of the lock body 1 and is concave with a square groove 5 that is connected to the external square rod for transmission, the transmission block 4 is concave with a card groove 6 along the circumferential side wall, and the handle 2 includes a straight body portion 21 The straight body 21 has a handle 22, and a side wall at one end thereof is provided with a connecting groove 23 which is engaged with the transmission block 4. The inner wall of the connecting groove 23 is provided with a flange 24 which is engaged with the clamping groove 6. A cover plate 7 which can abut against the side wall of the transmission block 4 is rotatably provided at the opening of the connecting groove 23. A limiting ring 8 which can abut against the outer side of the cover plate 7 is movably sleeved on the straight body 21. The limiting ring 8 is fixed to the straight body 21 by magnetism to maintain the abutment state against the cover plate 7.
[0021] Specifically, the handle is driven to move laterally through the connecting groove located thereon and engage with the transmission block, and then the flange in the connecting groove engages in the card groove of the transmission block to realize the pre-positioning connection between the handle and the transmission block. At this time, the cover plate is rotated relative to the connecting groove and limited to contact the outside of the transmission block, and the limiting ring moves axially along the straight body part and presses against the outside of the cover plate, and then the cover plate is in a connection state of maintaining contact with the transmission block, thereby realizing the installation connection between the handle and the transmission block located on the lock body. Conversely, when the handle needs to be disassembled, it is only necessary to move the limiting ring away from the cover plate, which is convenient for assembly and disassembly.
[0022] Furthermore, a torsion spring is provided at the rotation connection between the cover plate 7 and the connection slot 23, and the torsion spring is used to keep the cover plate 7 in an outwardly opened state relative to the connection slot 23. Then, when the limit ring moves axially along the straight body of the handle and is free from the contact with the cover plate, the cover plate can be flipped open relative to the connection slot and be free from the contact with the transmission block by the force of the torsion spring, and then the handle can be directly separated from the transmission block through the opening of the connection slot.
[0023] Furthermore, the side wall of the transmission block 4 that contacts the cover plate 7 is an inclined surface 41, the upper end of the inclined surface 41 contacts the inner side of the cover plate 7, and a gap is left between the lower part of the inclined surface 41 and the cover plate 7 to enable the cover plate 7 to flip toward the transmission block 4. The cover plate 7 is provided with a protrusion 71 on the outer side, and the protrusion 71 can contact or detach from the upper side of the limit ring 8 with the rotation of the cover plate 7. Furthermore, a limit plate 25 is provided along the circumference of the lower end of the straight body 21, and the limit ring 8 is tightly attached to the limit plate 25 by magnetic attraction of a magnet, and a limit structure for clamping the limit ring 8 is formed by the combination of the limit plate 25 and the protrusion 71.
[0024] Specifically, by providing an inclined surface on one side of the transmission block, and the cover plate is limited by the contact limit of the limiting ring so that the cover is placed on the opening of the connecting groove, the upper end of the inclined surface abuts against the inner side of the cover plate, thereby effectively avoiding loosening when the handle and the transmission block are matched and connected. Because there is a gap between the lower part of the inclined surface and the cover plate so that the cover plate can rotate relative to the straight body in the direction of the inclined surface, the user can press the cover plate to swing the cover plate in the direction of the inclined surface so that the protrusion of the cover plate is disengaged from the upper side of the limiting ring, so that the limiting ring can resume the active state of moving upward along the axial direction of the straight body to disengage from the cover plate. Conversely, when there is no external force acting on the cover plate, the cover plate can be subjected to the force of the torsion spring so that the protrusion thereon abuts against the upper side of the limiting ring.
[0025] Furthermore, the height of the connecting groove 23 is greater than the sum of the thickness of the cover plate 7 and the height of the transmission block 4 .
[0026] Furthermore, the transmission block 4 has a wire hole 42 in communication with the inner cavity of the lock body 1, and the handle 2 has a cavity 43 in communication with the wire hole 42, so as to facilitate the connection of the circuit when installing an electric control component on the handle.
[0027] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and the description are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
