Referring to fig. 1 to 7, an embodiment of the present invention provides a multifunctional lock, including a casing 100, a transmission assembly 200, a handle assembly 300, a first connecting member 400, a second connecting member 500, and a lock core 600.

Referring to fig. 1 and 2, it can be understood that the casing 100 is substantially a rectangular parallelepiped and is formed by connecting two shells, the casing 100 is provided with an inner cavity, an oblique tongue 110 and a main tongue 120 are slidably mounted in the inner cavity, the oblique tongue 110 and the main tongue 120 are both located at the left end of the casing 100 and slidably disposed along the left-right direction, wherein the oblique tongue 110 is located at the upper side of the main tongue 120, and the left side of the casing 100 is provided with two openings through which the oblique tongue 110 and the main tongue 120 respectively extend out of the casing 100. The right end of the latch tongue 110 is provided with a connecting plate 111, a return spring 113 is connected between the connecting plate 111 and the housing 100, and the latch tongue 110 can be driven to extend out of the housing 100 under the elastic force of the return spring 113.

Referring to fig. 1 and 2, it can be understood that the transmission assembly 200 is installed in the inner cavity and located at the right side of the main tongue 120, the fixed portion 160 is disposed in the casing 100, the fixed portion 160 is of a cylindrical structure, the transmission assembly 200 includes a first transmission member 210 and a second transmission member 220 rotatably installed at the fixed portion 160, each of the first transmission member 210 and the second transmission member 220 is of a plate-shaped structure, and the first transmission member 210 and the second transmission member 220 are layered along the axial direction of the fixed portion 160. The first transmission member 210 is connected to the main tongue 120, and rotates with the first transmission member 210 to drive the main tongue 120 to move in the left-right direction, the first transmission member 210 rotates clockwise to drive the main tongue 120 to move leftward, i.e., extend out of the housing 100, and the first transmission member 210 rotates counterclockwise to drive the main tongue 120 to move rightward, i.e., retract into the housing 100.

Referring to fig. 1 and 2, it can be understood that the handle assembly 300 is located at the right side of the latch bolt 110 and at the upper side of the transmission assembly 200, the handle assembly 300 includes a handle body 310 rotatably mounted to the housing 100, and a first pulling piece 320, a second pulling piece 330 and a third pulling piece 340 fixedly connected to the handle body 310, and the first pulling piece 320, the second pulling piece 330 and the third pulling piece 340 are plate-shaped structures and are arranged in a stacked manner along the rotation axis direction of the handle body 310. The third paddle 340 is in transmission connection with the connecting plate 111, specifically, a hook portion 341 protrudes radially from the outer periphery of the third paddle 340, the connecting plate 111 is bent to form the folded plate 112, and the hook portion 341 is located on the left side of the folded plate 112. In a natural state, the handle body 310 is arranged in the left-right direction, the handle body 310 is rotated in the clockwise direction (i.e., the second direction), the third shifting piece 340 can be driven to rotate, the hook portion 341 pushes the connecting plate 111 to move rightward through the folded plate 112, and thus the connecting plate 111 drives the latch bolt 110 to move rightward, i.e., the latch bolt 110 retracts into the casing 100, so as to open the door. It is easy to understand that, after releasing the handle body 310, the handle body 310 can be automatically reset.

Referring to fig. 1 and 2, it can be understood that the first pulling tab 320 is in one-way transmission connection with the first transmission member 210, specifically, when the handle body 310 is rotated in a counterclockwise direction (i.e., a first direction), the first pulling tab 320 can be driven to rotate counterclockwise, the first pulling tab 320 pushes the first transmission member 210 to rotate clockwise, and the main tongue 120 extends out of the casing 100, so as to lock the door. When the handle body 310 is rotated clockwise, the first pulling piece 320 cannot push the first transmission member 210 to rotate.

Referring to fig. 1 and 2, it can be understood that the second pulling piece 330 and the second transmission member 220 are located on the same plane and are connected in a one-way transmission manner, specifically, the handle body 310 is rotated clockwise to drive the second pulling piece 330 to rotate clockwise, and the second pulling piece 330 can push the second transmission member 220 to rotate counterclockwise. On the contrary, when the handle body 310 is rotated in the counterclockwise direction, the second driving piece 330 cannot push the second transmission member 220 to rotate.

Referring to fig. 1 to 3, it can be understood that the first connecting member 400 is detachably connected to the first transmission member 210 and the second transmission member 220. When the first connecting member 400 is connected to the first transmission member 210 and the second transmission member 220, the first transmission member 210 and the second transmission member 220 are relatively fixed, that is, the first transmission member 210 is in transmission connection with the second transmission member 220, therefore, when the handle body 310 is rotated clockwise, the second pick-up 330 can push the second transmission member 220 and the first transmission member 210 to synchronously rotate counterclockwise, so that the main tongue 120 retracts into the casing 100, and the main tongue 120 is driven by the handle body 310 to move to open the door. After the first connecting member 400 is detached, the first transmission member 210 is not connected to the second transmission member 220, even if the second pulling piece 330 pushes the second transmission member 220 to rotate counterclockwise, the second transmission member 220 idles relative to the first transmission member 210 and cannot drive the first transmission member 210 to rotate counterclockwise, that is, the handle body 310 cannot drive the main tongue 120 to move to open the door.

Referring to fig. 1, 2 and 4, it can be understood that the second connector 500 is detachably coupled to the housing 100.

After the second connecting piece 500 is disassembled, the main tongue 120 can be driven by the handle body 310 to move to lock the door, which is not described herein again.

Referring to fig. 1 and 2, it can be understood that the lock core 600 is installed in the casing 100 and located at the lower side of the transmission assembly 200, the lock core 600 is in bidirectional transmission connection with the first transmission member 210, and the lock core 600 can be driven by a key to drive the first transmission member 210 to rotate, so as to further drive the main tongue 120 to extend out of the casing 100 or retract into the casing 100. Specifically, the lock core 600 is rotated clockwise to drive the first transmission member 210 to rotate counterclockwise, so that the main tongue 120 retracts into the housing 100 to open the door; the lock core 600 is rotated counterclockwise to drive the first transmission member 210 to rotate clockwise, and the main tongue 120 extends out of the housing 100 to lock the door.

According to the above arrangement, the multifunction lock can be converted into the following four types of locks.

The first type is: the first connector 400 is detached and the second connector 500 is installed.

When the door is closed, the latch bolt 110 retracts into the casing 100 under pressure and then resets, and because the second connecting piece 500 blocks the first shifting piece 320 from rotating counterclockwise, the main bolt 120 cannot be driven to extend out of the casing 100 by rotating the handle body 310 counterclockwise so as to lock the door, and the main bolt 120 needs to be driven to extend out of the casing 100 by the lock core 600 so as to lock the door, which is a slow lock type.

When the door is opened, the first transmission member 210 is not connected to the second transmission member 220, and the main bolt 120 cannot be driven to retract into the casing 100 by rotating the handle body 310 clockwise, and the main bolt 120 needs to be driven to retract into the casing 100 by the lock core 600 and the handle body 310 is rotated clockwise, so that the latch bolt 110 retracts into the casing 100, namely, the slow-opening type.

The second type: the first connector 400 is detached and the second connector 500 is detached.

When the door is closed, the latch bolt 110 retracts into the shell 100 under pressure and then resets, and the handle body 310 is rotated counterclockwise to drive the main bolt 120 to extend out of the shell 100, so that the door is locked, namely, the quick lock type.

When the door is opened, the first transmission member 210 is not connected to the second transmission member 220, and the main bolt 120 cannot be driven to retract into the casing 100 by rotating the handle body 310 clockwise, and the main bolt 120 needs to be driven to retract into the casing 100 by the lock core 600 and the handle body 310 is rotated clockwise, so that the latch bolt 110 retracts into the casing 100, namely, the slow-opening type.

The third type: the first connector 400 is mounted and the second connector 500 is detached.

When the door is closed, the latch bolt 110 retracts into the shell 100 under pressure and then resets, and the handle body 310 is rotated counterclockwise to drive the main bolt 120 to extend out of the shell 100, so that the door is locked, namely, the quick lock type.

When the door is opened, since the first transmission member 210 and the second transmission member 220 are relatively fixed by the first connection member 400, the oblique tongue 110 and the main tongue 120 can be driven to retract into the casing 100 by clockwise rotating the handle body 310, so that the door is opened, i.e., the quick-open type.

The fourth type: the first connector 400 is installed and the second connector 500 is installed.

When the door is closed, the latch bolt 110 retracts into the casing 100 under pressure and then resets, and because the second connecting piece 500 blocks the first shifting piece 320 from rotating counterclockwise, the handle body 310 cannot be rotated counterclockwise to drive the main bolt 120 to extend out of the casing 100 to lock the door, and the lock core 600 needs to drive the main bolt 120 to extend out of the casing 100 to lock the door, which is a slow lock type.

When the door is opened, since the first transmission member 210 and the second transmission member 220 are relatively fixed by the first connection member 400, the oblique tongue 110 and the main tongue 120 can be driven to retract into the casing 100 by clockwise rotating the handle body 310, so that the door is opened, i.e., the quick-open type.

It is easy to understand that, for the third type and the fourth type, since the type is the quick-opening type, the door can be opened by the handle body 310, and the operation is convenient, such as being suitable for a fire door. If the anti-theft function is needed, the handle body 310 needs to be controlled by being matched with an electronic lock.

Meanwhile, since the first connecting member 400 is fixed by a screw connection manner and is detachable, the door cannot be opened by driving the main tongue 120 to move through the handle body 310 after the first connecting member 400 is detached. The first connecting member 400 is simple in structure and connection manner and easy to implement. Of course, it is understood that the positions of the first through hole 211 and the first screw hole 221 on the first transmission member 210 and the second transmission member 220 may be interchanged.

Referring to fig. 3, it can be understood that the housing 100 is provided with the avoiding hole 130, generally speaking, the aperture of the avoiding hole 130 is larger than the outer diameter of the first connecting member 400, and the first connecting member 400 can be connected to the first transmission member 210 and the second transmission member 220 through the avoiding hole 130, so that the first connecting member 400 is convenient to install and detach, and the conversion into different types of locks is realized.
