[0039] like Figure 1-2 As shown, a split door lock comprises:

[0040] A housing 1;

[0041] A lock body 2 is disposed in the housing 1 and is detachably disposed from the housing 1. A first handle 3 and a second handle 4 are respectively disposed on both sides of the lock body 2.

[0042] An expansion component is provided in 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 handles, retaining the basic skills, and then cooperating with the expansion component, the expansion component can be installed at the position of the housing 1 according to the needs and height, so that the function combination is very flexible and can meet the needs of different user groups. Even if the user needs to install additional components later, there is no need to replace the door lock, which reduces the user's use cost; at the same time, the expansion component is arranged above the first handle 3 and the second handle 4. The expansion component includes an identification device 7. The identification device 7 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 performed without bending over to aim at the door handle, which is easy to use and can adapt to user groups of different heights.

[0043] like Figure 1 and Figure 3 As shown, a plurality of assembly holes 11 are respectively provided on both sides of the shell 1, a connecting plate 12 is located in the shell 1 and is assembled with the assembly hole 11, and the identification device 7 is assembled with the connecting plate 12, so that the identification device 7 is assembled with the shell 1, and 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 users to disassemble and assemble.

[0044] like Figure 4 As shown, it also includes a plurality of first elastic members 8, and 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, and the first spiral portion 81 acts as a torsion and is compressible; 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 the first elastic arm 82 and the second elastic arm 83 are both perpendicular to the first spiral portion 81.

[0045] A connecting member 84 is connected to the first elastic arm 82, and the connecting member 84 is used to cooperate with the shell 1 to better fix the display device 5 and the observation device 6 in the shell 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.

[0046] In this embodiment, the first elastic member 8 is a torsion spring, and the connecting member 84 is integrally formed with the first elastic member 8. The integrally formed arrangement can improve the performance of the product, reduce costs, and improve production efficiency. The connecting member 84 and the first elastic arm 82 form a rectangle, which is stable in structure and 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 makes the force more balanced, prolongs the service life of the first elastic member 8, and the first elastic member 8 provides force support for the connecting member 84, which increases the stability of the connecting member 84 when in use.

[0047] like Figure 5-8 As shown, the display device 5 includes a first rear cover 51 and a display element 52. The rear cover 2 and the display device 51 are detachable, specifically by bolt connection, to facilitate disassembly and assembly by the user.

[0048] The first back cover 51 is provided with two first openings 53, and each first opening 53 is provided with at least one first protrusion 54. Specifically, two ends of the opening are respectively provided with a first protrusion 54 opposite to each other (that is, each opening is provided with two first protrusions 54). The first protrusion 54 serves as the rotating axis of the first elastic member 8, and the first protrusion 54 is rectangular in shape with a large contact area, so that the first elastic member 8 is better limited on the first protrusion 54.

[0049] 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 .

[0050] 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 torque for the first spiral portion 81 and helping the first spiral portion 81 and the connecting member 84 to reset.

[0051] like Figure 7-8As shown, in this embodiment, the first opening 53 is formed by opening the adjacent two end surfaces, that is, the first opening 53 is arranged in an I-shape, which can increase the range of movement of the first elastic member 8 and the connecting member 84, so that the first elastic member 8 and the connecting member 84 can be further adapted to plates of different thicknesses.

[0052] like Figure 9-10 As shown, the observation device 6 includes a housing 61 , a front end surface of the housing 61 is provided with a panel 62 , and the panel 62 is provided with an infrared sensor 621 , a cat's eye 622 and a fill light 623 .

[0053] Two second openings 63 are provided at the rear end of the shell 61, and each second opening 63 is provided with at least one second protrusion 64. The first spiral portion 81 is connected to the second protrusion 64 so that the first spiral portion 81 can rotate relative to the second protrusion 64. The third connecting portion 843 is passed 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 torque for the first spiral portion 81 and helping the first spiral portion 81 and the connecting member 84 to reset.

[0054] By cooperating with 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 shell 1 of different thicknesses, thereby improving versatility. At the same time, after being fixed, the display device 5 and the observation device 6 will be closer to the shell 1, reducing the range of the display device 5 and the observation device 6 protruding from the shell 1, making the split door lock more neat and beautiful as a whole.

[0055] like Fig. 9 As shown, the panel 62 is inclined to the front face of the housing 61, and the panel 62 and the front face of the housing 61 form an angle a, which is 30°-45°. In this embodiment, the specific angle of the angle a is 32.5°. When the panel 62 does not protrude and is not blocked by the bottom of the front face of the housing 61, the user can better see the outdoor situation through the display device 5. Of course, the observation device 6 is not only used outdoors, but also indoors. For example, the cat's eye 622 can be replaced with a camera similar to a surveillance camera, which can be used to observe the indoor situation and facilitate the observation of the safety of children and the elderly indoors.

[0056] like Figure 11-16 As 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 to match the rear plate 32. The protective shell 33 is provided with a notch 331. A mounting member 34 is provided inside the protective shell 33.

[0057] A knob 35 is matched with the mounting member 34, and a portion of the knob 35 is located outside the notch 331;

[0058] A second elastic member 36 is disposed between the knob 35 and the mounting member 34 .

[0059] The knob 35 includes a connecting block 351, which has a mounting hole 352, a groove 353 on one side of the connecting block 351, a protruding column 354 extending outward on the other side, and a pull rod 355 on the top of the connecting block 351;

[0060] The front end surface of the mounting member 34 is provided with a plurality of first mounting portions 37, and the rear end surface is provided with a plurality of second mounting portions 38, wherein a first mounting portion 37 cooperates with the connecting block 351 located in the mounting hole 352, and the front end surface of the mounting member 34 is provided with a flange 39, and the flange 39 cooperates with the groove 353 to limit the second elastic member 36, which can effectively prevent the second elastic member 36 from being stuck in the gap due to the thin wire diameter, thereby affecting subsequent use.

[0061] The knob 35 is L-shaped, the mounting hole 352 is semi-circular, and the distance between the end of the pull rod 355 and the middle of the connecting block 351 is greater than the distance between the end of the boss 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, thereby improving the user experience and achieving the effect of quick unlocking.

[0062] When too many first mounting parts 37 are located in the mounting hole 352, the rotation of the entire knob 35 will be hindered. In this embodiment, the front end face of the mounting part 34 is set as a right triangle, and the rear end face is set as an inverted triangle, so that the first mounting part 37 and the second mounting part 38 are staggered. The 3+3 staggered arrangement not only ensures that the first mounting part 37 will not hinder the rotation of the knob 35, but also ensures the strength of use through the stability of the triangle. At the same time, it also ensures that the user will not block the screwdriver when tightening the screw, which is convenient for the user to disassemble and assemble.

[0063] The second elastic member 36 includes a second spiral portion 361, and a third elastic arm 362 and a fourth elastic arm 363 extending along the second spiral portion 361 are respectively provided at both ends of the second spiral portion 361, and the third elastic arm 362 and the fourth elastic arm 363 are both perpendicular to the second spiral portion 361; the end surface of the connecting block 351 opposite to the mounting member 34 is respectively provided with a first stopper 39 and a second stopper 30 matched with the third elastic arm 362 and the fourth elastic arm 363. When the pull rod 355 is pulled to the left or right, the third elastic arm 362 or the fourth elastic arm 363 will resist the first stopper 39 or the second stopper 30. Once the pull rod 355 loses external force, the third elastic arm 362 or the fourth elastic arm 363 will drive the entire knob 35 to reset.

[0064] The technical effects of this utility model are mainly reflected in the following aspects:

[0065] It allows users to better observe their surroundings.

[0066] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
