DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0024] This embodiment discloses a reverse lift lock body, such as Figure 1-5As shown, the lock body 1 includes a lock tongue 2 and a dial wheel 3 that match each other, a dial rod on the dial wheel 3, and a dial block on the lock tongue 2. The dial rod and the dial block cooperate with each other so that the lock tongue 2 can be driven to move when the dial wheel 3 rotates in the unlocking direction. Specifically, the dial wheel 3 is used to drive the lock tongue 2 to retract into the lock body, and the extension of the lock tongue can adopt a magnetic door lock. After the door is closed, the lock tongue can be sucked out by magnetic attraction. Back to the present embodiment, a rotatably connected square chip 5 is provided on the dial wheel 3. Specifically, the square chip 5 includes A501 and square chip B502. The square chip A501 and the square chip B502 are respectively arranged on the front and rear sides of the dial wheel 3. The square chip A501 is connected to the outer handle on the door, and the square chip B502 is connected to the inner handle on the door. Refer to Figure 1-2 A movable adapter 6 is provided on the dial wheel 3, and a linkage part A401 and a linkage part B402 are provided on the square chip 5. The adapter 6 has a first station and a second station. Taking the square chip A501 connected to the outer handle as an example, refer to Figure 1 In the first station, the adapter 6 is located on the unlocking rotation stroke of the square chip A501, and cooperates with the linkage part A401, so that the square chip A501 can drive the dial 3 to rotate along the unlocking direction; refer to Figure 2 , when in the second position, the adapter 6 is separated from the unlocking rotation stroke of the square chip A501, so that the square chip A501 rotates independently. Through the above structure, when the adapter 6 is in the first position, when the outer handle drives the square chip A501 to rotate in the unlocking direction (pressing down to rotate), the square chip A501 will abut against the adapter 6, thereby driving the dial wheel 3 to rotate together, driving the lock tongue 2 to retract into the lock body 1, and unlocking is achieved; while in the second position, the square chip A501 independently rotates idly and does not contact the adapter 6, so it cannot be unlocked.

[0025] For further information, please refer to Figure 1 and Figure 4 , when in the first station, the linkage part A401 abuts against the movable end of the adapter 6; and when the square chip 5 rotates in the locking direction (lifting the outer handle or the inner handle upward), the linkage part B402 abuts against one side of the adapter 6 and moves the adapter 6 to the second station. Through the above structure, when the inner handle or the outer handle is lifted upward, the corresponding square chip A501 or square chip B502 is driven to rotate in the locking direction, so that the linkage part B402 contacts the adapter 6, thereby moving the adapter 6 from the first station to the second station, realizing the reverse lifting and locking function. Specifically, in order to ensure the simplicity of the structure, a linkage groove 7 can be set on the square chip 5, and the ends on both sides of the linkage groove 7 respectively form the linkage part A401 and the linkage part B402.

[0026] Furthermore, the door should be opened when the inner handle is rotated in the unlocking direction regardless of whether it is locked or not, so a transmission assembly 9 is provided on the thumbwheel 3 and the square chip B502, and the transmission assembly 9 is used to link the square chip B502 and the thumbwheel 3 to rotate in the unlocking direction. Figure 5 The transmission assembly 9 includes a fixing member 901 and a hook body 902 respectively arranged on the dial wheel 3 and the square chip B502, and the hook body 902 is in abutment with one side of the fixing member 901. Figure 5 In the embodiment, the fixing member 901 is arranged on the dial wheel 3, and the hook body 902 is arranged on the square chip B502. In fact, the fixing member 901 can also be arranged on the square chip B502, and the hook body 902 can be arranged on the dial wheel 3. After the modification, it is only necessary to adjust the direction of the hook body at the same time. After the transmission assembly 9 is arranged, when the inner handle drives the square chip B502 to rotate in the unlocking direction, the dial wheel 3 can be driven to rotate, thereby unlocking. In order to keep the structure simple, the fixing member 901 can be a rivet or a screw, etc., for easy assembly.

[0027] Furthermore, a reset member 8 is provided in the lock body 1, and the reset member 8 cooperates with the adapter 6. When the dial wheel 3 rotates in the unlocking direction, the reset member 8 pushes the adapter 6 to move to the first position. Figure 3 Through the above-mentioned reset member 8, when the dial wheel 3 is rotated to unlock, the reset member 8 will cooperate with the adapter 6. If the adapter 6 is in the second position, the reset member 8 will push the adapter 6 back to the first position, so that the adapter 6 cooperates with the square chip 5. Therefore, every time the dial wheel 3 is unlocked and rotated once, the adapter 6 will return to the first position.

[0028] Furthermore, the adapter 6 needs to remain stable after moving to the first station or the second station, so a first card slot 301 and a second card slot 302 are provided on the dial wheel 3, and a retractable card bead 10 is provided on the adapter 6, wherein the retractable card bead 10 includes a spring and a card bead inside, and a portion of the card bead is extended by the drive of the spring, and the extended portion is adapted to the first card slot 301 and the second card slot 302, thereby achieving that in the first station, the retractable card bead 10 cooperates with the first card slot 301, and in the second station, the retractable card bead 10 cooperates with the second card slot 302. The retractable card bead 10 maintains the stability of the adapter 6 after it reaches the station, and at the same time, there is a certain sense of frustration when the adapter 6 moves to the corresponding station, which has better usage feedback.

[0029] Furthermore, an unlocking function needs to be provided on the outer handle, so a flat bar hole 11 is provided on the thumbwheel 3, a flat bar (not shown in the figure) is provided in the flat bar hole 11, and the flat bar extends to the outer handle on the door, and a rotatable unlocking element (not shown in the figure) is provided on the outer handle, and the unlocking element is fixedly connected to the flat bar. The unlocking element can be a lock core that requires a key to rotate. When the key is inserted, the key rotates in the unlocking direction, driving the unlocking element to rotate, thereby driving the flat bar to rotate, and the flat bar drives the thumbwheel 3 to rotate, thereby unlocking. It should be noted that the unlocking element can also be provided as a simple rotatable cylinder with a slotted groove on the cylinder, so that a slotted screwdriver or a flat tool can be used to rotate the unlocking element to unlock the door, which is more versatile.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
