Description

Technical Field

[0001] The utility model relates to a door lock used for an indoor door, in particular to a plane lock. Background Art

[0002] The handle of the flat door lock is hidden in the panel frame, without a protruding handle. It not only improves the aesthetics of the door lock, but also makes it less likely for the door handle to get caught on clothing, backpack straps and other items. It is becoming more and more popular. After the handle of a general flat lock is lifted, a series of transmissions are required to drive the lock body to unlock. The existing transmission mechanism is not reasonable enough, and the assembly is troublesome. The transmission parts occupy a large space and volume, which makes the size and thickness of the panel frame larger, affecting the installation and aesthetics, and increasing the cost. Summary of the invention

[0003] In view of the deficiencies of the prior art, the utility model provides a handle driving structure of a plane lock which has a reasonable structure and reduces the size and thickness of a panel frame.

[0004] The utility model comprises a hand-pulling piece rotatably connected to a panel frame on one side, the hand-pulling piece and a push piece with a reset spring are linked together, a thin transmission piece is rotatably connected in the panel frame, one end of the transmission piece is linked together with the push piece; a thin unlocking drive piece is rotatably connected in the panel frame, a square hole is provided in the center of the unlocking drive piece for corresponding to the square axis of the lock body, and one side of the unlocking drive piece is provided with transmission teeth that mesh with the end of the adjacent transmission piece.

[0005] The utility model has a short transmission route from the finger-pulling to the unlocking drive, a reasonable and simple structure, few parts, and is easy to assemble. The transmission parts used are all thin, the transmission cooperation is direct and efficient, and the space volume occupied is small, so that the size and thickness of the panel frame can also be correspondingly smaller, which is easier to install on the door leaf and improves the aesthetics.

[0006] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] like Figures 1 to 3 As shown, one side of the pull handle 2 is rotatably connected to the panel frame 1, and the pull handle 2 is linked with a push piece 3 with a return spring 4. A thin transmission member 5 is rotatably connected in the panel frame 1, and one end of the transmission member 5 is linked with the push piece 3. A thin unlocking drive member 6 is rotatably connected in the panel frame 1, and a square hole 7 is provided in the center of the unlocking drive member 6 for corresponding to the square axis of the lock body, and one side of the unlocking drive member 6 is provided with a transmission tooth 8 that meshes with the end of the adjacent transmission member 5.

[0014] In this embodiment, the push piece 3 is stacked on the thin transmission member 5, the lower end surface of the push piece 3 is provided with a convex handle 9, one end of the transmission member 5 is provided with a through hole 10, and the convex handle 9 is placed in the through hole 10 and can move in the gap to form a linkage fit. Figure 4 shown.

[0015] When in use, the handle member 2 is lifted and rotated, causing the push piece 3 to move, thereby rotating the transmission member 5. Through the meshing transmission teeth 8, the unlocking drive member 6 is also rotated, which can drive the correspondingly installed lock body square shaft to unlock.

[0016] In this embodiment, a safety button assembly 11 is rotatably connected in the panel frame 1, and a planarly displaceable anti-locking piece 12 is arranged in the panel frame 1 and cooperates with the safety button assembly 11. A protruding blocking piece 13 is provided on the side wall of the unlocking drive member 6, and the blocking piece 13 and the anti-locking piece 12 block the displacement end.

[0017] like Figure 5 As shown, it is only necessary to rotate the safety button assembly 11 to drive the anti-locking plate 12 to translate, and the displacement end of the anti-locking plate 12 occupies the displacement space of the blocking plate 13, so that the unlocking drive member 6 is blocked and cannot rotate, and cannot be unlocked, and is in a safety anti-locking state.

[0018] In fact, if Figure 6 As shown, the panel frame 1 is generally used in pairs of two, which are respectively installed on the inside and outside of the door leaf. Usually, the safety button assembly 11 in the panel frame 1 outside the door leaf can be replaced with a lock core assembly, and the lock core can be turned by a key outside the door to lock the door. The rotating shaft 14 synchronously rotates to connect the safety button assembly 11 and the lock core assembly in the two panel frames 1, so that the two can synchronously lock or unlock the safety.
