[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-3, an embodiment of the utility model is provided: a lever-type plane lock, comprising an external lock body 1, an internal lock body 2 is arranged on one side of the inner wall of the external lock body 1, and sockets 8 are arranged on the upper and lower sides of the inner wall of the external lock body 1, and the upper and lower sides of the inner wall of the internal lock body 2 are slidably connected to the inside of the socket 8, and the upper and lower sides of the outer wall of the internal lock body 2 are rotatably connected with a hexagonal control block 6, and one side of the inner wall of the hexagonal control block 6 is fixedly connected with a connecting rod 7, and one end of the connecting rod 7 is fixedly connected with a positive and negative threaded rod 10, and the positive and negative threaded rod 10 is rotatably connected to the inside of the internal lock body 2, and the outer wall of the positive and negative threaded rod 10 is threadedly connected with a left-right symmetrical moving block 11, and the outer wall of the moving block 11 is rotatably connected with a transmission rod 12 in an annular array, and one end of the transmission rod 12 is rotatably connected with a card block 13, and the card block 13 is slidably connected to the inside of the internal lock body 2, and the upper and lower sides of the external lock body 1 are provided with sockets 8, and the inside of the socket 8 is provided with a card slot 9 in an annular array, and the card block 13 is slidably connected to the inside of the card slot 9;

[0026] Specifically, the flat lock is composed of an external lock body 1 and an internal lock body 2. When the lock is disassembled, the hexagonal control block 6 can be rotated on the internal lock body 2, thereby driving the positive and negative screw rods 10 to rotate through the connecting rod 7. The connecting rod 7 can extend the control distance. Under the rotation of the positive and negative screw rods 10 and the restriction of the card block 13, the moving blocks 11 on both sides can be driven to tighten inward, so that the moving blocks 11 will drive the transmission rod 12 to move. Under the movement of the transmission rods 12 on both sides, the card block 13 will be pushed out from the inside of the internal lock body 2, and thus be stuck in the card slot 9 set in the socket 8, so that the external lock body 1 and the internal lock body 2 are fixed, and the hexagonal control block 6 is designed on the internal lock body 2, and the internal lock body 2 is installed inside the door, so that the hexagonal control block 6 does not disturb the firmness of the door lock while making the door lock easy to disassemble.

[0027] Reference Figure 1 and Figure 2 The outer wall of the external lock body 1 is provided with a control component, and the control component includes a key control hole 3 and a knob control hole 5. The key control hole 3 is arranged on the inner bottom side of the external lock body 1, and the knob control hole 5 is arranged on the inner bottom side of the internal lock body 2;

[0028] Specifically, the key control hole 3 is installed inside the external lock body 1 and needs to be opened by a key to ensure its privacy, while the knob control hole 5 is installed inside the internal lock body 2 and can be directly turned and unscrewed, so that it is convenient to open from the inside.

[0029] Reference Figure 4-6A control rod 14 is arranged on the top side of the inner lock body 2, and the outer wall of the control rod 14 is rotatably connected to the handle 4, a control column 17 is threadedly connected to one side of the inner part of the control rod 14, and a rotating column 16 is slidably connected to the inner part of the control rod 14, and one side of the outer wall of the control column 17 is rotatably connected to one side of the inner part of the rotating column 16, and a slide groove 18 is provided on both sides of the inner part of the handle 4, and both sides of the outer wall of the rotating column 16 are slidably connected to the inner part of the slide groove 18, and a slide groove 29 is provided on both sides of the inner part of the rotating column 16, and a slide rod 21 is slidably connected to the inner part of the slide groove 21, and a spring 20 is arranged inside the slide groove 29, and a card groove 25 is provided on both sides of the inner wall of the control rod 14 for the slide rod 21 to be embedded;

[0030] Specifically, to prevent children from accidentally touching the door, the control column 17 can be rotated, and the limiting part of the control column 17 can drive the rotating column 16 to slide outward, and can be limited by the slide groove 18. After the rotating column 16 moves outward, the slide rod 21 will overcome the force of the spring 20 and be pressed into the inside of the slide groove 19, so that the handle 4 rotates inside the control rod 14, and the handle 4 cannot be used to open the door. After the rotating column 16 is inserted into the second slot 15, the control rod 14 can be controlled to rotate by the handle 4, so that the door lock can be opened.

[0031] Working principle: When disassembling the lock, the hexagonal control block 6 can be rotated on the internal lock body 2, thereby driving the positive and negative screw rods 10 to rotate through the connecting rod 7. With the rotation of the positive and negative screw rods 10, the moving blocks 11 on both sides can be driven to tighten inward, so that the moving blocks 11 drive the transmission rod 12 to move. With the movement of the transmission rods 12 on both sides, the card block 13 can be pushed out from the inside of the internal lock body 2, so as to be stuck in the card slot 1 9, so that the external lock body 1 and the internal lock body 2 are fixed. When preventing children from accidentally touching it, the control column 17 can be rotated outward, thereby driving the rotating column 16 to move outward. After the rotating column 16 moves outward, the slide bar 21 will be pressed into the inside of the slide slot 2 19, so that the handle 4 is idle inside the control rod 14, which can prevent children from accidentally touching it.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
