Therefore, it will not be elaborated in this embodiment.

[0039] The following combines the attached Figures 1-16 to further explain this application in detail.

[0040] As Figures 1-2 shown, a split door lock includes:

[0041] A housing 1;

[0042] A lock body 2 is provided inside the housing 1 and is detachably arranged with the housing 1. A first handle 3 and a second handle 4 that cooperate with each other are respectively provided on both sides of the lock body 2.

[0043] An expansion component is provided inside the housing 1 and is detachably arranged with the housing 1. The expansion component is located above the first handle 3 and the second handle 4. The expansion component includes a display device 5, an observation device 6, and an identification device 7. By splitting the functions on the handle and retaining the basic functions, and then cooperating with the expansion component, the expansion component can be installed at the position of the housing 1 according to requirements and height, making the function combination very flexible and capable of meeting the needs of different user groups. Even if the user needs to add additional components later, there is no need to replace the door lock again, reducing the user's usage cost. At the same time, the expansion component is provided above the first handle 3 and the second handle 4, and the expansion component includes an identification device 7 which has the function of face recognition. The user only needs to install it according to the height of himself and the people around him, so that face recognition can be carried out without bending down to align with the door handle, which is convenient to use and can be adapted to user groups of different heights.

[0044] As Figure 1 and Figure 3 shown, a plurality of assembly holes 11 are respectively provided on both sides of the housing 1. A connecting plate 12 is located inside the housing 1 and is assembled with the assembly holes 11. The identification device 7 is assembled with the connecting plate 12 so that the identification device 7 is assembled with the housing 1. The identification device 7 includes functions such as face recognition, palm vein, and doorbell. Since the above functions belong to the prior art, the implementation methods of the above functions will not be described in detail here. At the same time, the identification device 7 and the connecting plate 12 are connected by bolts, which is convenient for the user to disassemble and assemble.

[0045] As Figure 4 shown, it further includes a plurality of first elastic members 8. The display device 5 and the observation device 6 are respectively provided with a plurality of first elastic members 8. The first elastic member 8 includes a first spiral portion 81 which plays a role of torsion and can be compressed. A first elastic arm 82 and a second elastic arm 83 extending along the first spiral portion 81 are respectively provided at both ends of the first spiral portion 81, and both the first elastic arm 82 and the second elastic arm 83 are perpendicular to the first spiral portion 81.

[0046] A connecting member 84 is connected to the first elastic arm 82. The connecting member 84 is used to cooperate with the housing 1 to better fix the display device 5 and the observation device 6 in the housing 1. The connecting member 84 includes a first connecting portion 841 connected to the first elastic arm 82 and a second connecting portion 842 connected to the first connecting portion 841. The first connecting portion 841 is parallel to the first spiral portion 81, the second connecting portion 842 is parallel to the first elastic arm 82, and a third connecting portion 843 is provided at one end of the second connecting portion 842 away from the first connecting portion 841, and the third connecting portion 843 extends into the first spiral portion 81.

[0047] In this embodiment, the first elastic member 8 is a torsion spring, and the connecting member 84 and the first elastic member 8 are integrally formed. By the integral forming arrangement, the performance of the product can be improved, the cost can be reduced, and the production efficiency can be increased. The connecting member 84 and the first elastic arm 82 form a rectangle, and the structure is stable, which can provide a better fixing effect. The second connecting portion 842 is arranged on the side facing the second elastic arm 83, which saves space and has a more balanced force, prolongs the service life of the first elastic member 8, and the first elastic member 8 provides a force support for the connecting member 84, increasing the stability of the connecting member 84 during use.

[0048] As Figures 5-8 shown, the display device 5 includes a first rear cover 51 and a display member 52. The rear cover 2 and the display device 51 are detachably arranged, specifically by means of bolt connection, which is convenient for the user to disassemble and assemble.

[0049] The first rear cover 51 is provided with two first openings 53. Each first opening 53 is provided with at least one first protrusion 54. Specifically, a first protrusion 54 (i.e., two first protrusions 54 are provided for each opening) is provided at both ends of the opening opposite to each other. The first protrusion 54 serves as the rotation axis of the first elastic member 8, and the first protrusion 54 is rectangularly arranged with a large contact area, and the first elastic member 8 is better limited on the first protrusion 54.

[0050] The first spiral portion 81 is connected to the first protrusion 54 so that the first spiral portion 81 can rotate relative to the first protrusion 54. The third connecting portion 843 passes through the first protrusion 54 to better fix the first elastic member 8 on the first protrusion 54.

[0051] In this embodiment, the second elastic arm 83 is located in the first opening 53, further limiting the first spiral portion 81 on the first protrusion 54, providing a certain torsion for the first spiral portion 81, and helping the first spiral portion 81 and the connecting member 84 to reset.

[0052] As Figures 7-8As shown, in this embodiment, the first opening 53 is formed by opening adjacent end faces, that is, the first opening 53 is arranged in an I-shape, which can increase the movement range of the first elastic member 8 and the connecting member 84, so that the first elastic member 8 and the connecting member 84 can further adapt to plates of different thicknesses.

[0053] As Figures 9-10 shown, the observation device 6 includes a housing 61, a front panel 62 is provided on the front end face of the housing 61, and an infrared sensor 621, a cat's eye 622 and a supplementary light 623 are provided on the front panel 62.

[0054] Two second openings 63 are formed at the rear end of the housing 61, at least one second protrusion 64 is provided in each second opening 63, the first spiral portion 81 is connected to the second protrusion 64 so that the first spiral portion 81 rotates relative to the second protrusion 64, and the third connecting portion 843 passes through the second protrusion 64 to better fix the first elastic member 8 on the second protrusion 64; in this embodiment, the second elastic arm 83 is located in the second opening 63, further limiting the first spiral portion 81 on the second protrusion 64, and also providing a certain torsion for the first spiral portion 81 and helping the first spiral portion 81 and the connecting member 84 to reset.

[0055] Through the cooperation of the first elastic member 8 and the connecting member 84, the first elastic member 8 drives the connecting member 84 to move, so that the display device 5 and the observation device 6 can be fixed on the housing 1 of different thicknesses, improving versatility. At the same time, after being fixed, the display device 5 and the observation device 6 will be closer to the inside of the housing 1, reducing the range where the display device 5 and the observation device 6 protrude from the housing 1, making the overall split-type door lock more tidy and beautiful.

[0056] As Figure 9 shown, the front panel 62 is inclined to the front end face of the housing 61, and an included angle a is formed between the front panel 62 and the front end face of the housing 61. The included angle a is 30°-45°. In this embodiment, the specific angle of the included angle a is 32.5°. Without the front panel 62 protruding and being blocked by the bottom of the front end face of the housing 61, users can better see the situation outside through the display device 5. Of course, the observation device 6 is not only used outdoors, but also can be used indoors. For example, by replacing the cat's eye 622 with a camera similar to a monitor, it can be used to observe the indoor situation, facilitating the observation of the safety of children and the elderly indoors.

[0057] As Figures 11-16 shown, the first handle 3 includes a front plate 31 and a rear plate 32. A protective shell 33 is provided at the rear end of the front plate 31 and cooperates with the rear plate 32. The protective shell 33 is provided with a notch 331, and a mounting member 34 is provided inside the protective shell 33.

[0058] A knob 35 cooperates with the mounting member 34, and a part of the knob 35 is located outside the notch 331.

[0059] A second elastic member 36 is disposed between the knob 35 and the mounting member 34.

[0060] The knob 35 includes a connecting block 351. The connecting block 351 is provided with a mounting hole 352. One side of the connecting block 351 is provided with a groove 353, and the other side is provided with a convex column 354 extending outward. The top of the connecting block 351 is provided with a lever 355.

[0061] The front end face of the mounting member 34 is provided with a plurality of first mounting portions 37, and the rear end face is provided with a plurality of second mounting portions 38. One of the first mounting portions 37 is engaged with the connecting block 351 in the mounting hole 352. The front end face of the mounting member 34 is provided with a flange 39. The flange 39 is engaged with the groove 353 to define the second elastic member 36, which can effectively prevent the second elastic member 36 from being stuck in the gap due to too thin wire diameter and affecting subsequent use.

[0062] The knob 35 is L-shaped, the mounting hole 352 is semi-circular, and the distance between the end of the lever 355 and the middle of the connecting block 351 is greater than the distance between the end of the convex column 354 and the middle of the connecting block 351, so as to form a labor-saving lever, making it easier for the user to pull the knob 35 and improving the user experience to achieve the effect of quick unlocking.

[0063] When too many first mounting portions 37 are located in the mounting hole 352, it will hinder the rotation of the entire knob 35. In this embodiment, the front end face of the mounting member 34 is a regular triangle, and the rear end face is an inverted triangle, so that the first mounting portions 37 and the second mounting portions 38 are arranged in a staggered manner. Through the 3+3 staggered arrangement, not only can it be ensured that the first mounting portions 37 do not hinder the rotation of the knob 35, but also the strength of use is ensured through the stability of the triangle, and at the same time, it is ensured that the user does not block the screwdriver when screwing the screw, which is convenient for the user to disassemble and assemble.

[0064] The second elastic member 36 includes a second spiral portion 361. Both ends of the second spiral portion 361 are respectively provided with a third elastic arm 362 and a fourth elastic arm 363 extending along the second spiral portion 361, and both the third elastic arm 362 and the fourth elastic arm 363 are perpendicular to the second spiral portion 361. The end faces of the connecting block 351 opposite to the mounting member 34 are respectively provided with a first limiting member 301 and a second limiting member 30 that cooperate with the third elastic arm 362 and the fourth elastic arm 363. When the lever 355 is pulled left or right, the third elastic arm 362 or the fourth elastic arm 363 will abut against the first limiting member 301 or the second limiting member 30. Once the external force on the lever 355 is lost, the third elastic arm 362 or the fourth elastic arm 363 will drive the entire knob 35 to reset.

[0065] The technical effects of the present utility model are mainly reflected in the following aspects:

[0066] It can facilitate the user to quickly unlock.

[0067] Of course, the above are only typical examples of the present utility model. In addition, the present utility model can also have many other specific implementation manners. Any technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection required by the present utility model.
