The battery of a common electronic lock is installed in the rear panel or rear handle inside the door, and the front panel or front handle outside the door is equipped with a fingerprint head or password key. The electronic function communication connection between the front panel and the rear panel usually requires threading and docking, which is inconvenient for customers to install and poor plug-in affects reliability. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a door lock structure. The purpose of the present invention is to overcome the defect that the above electronic lock needs to be threaded and connected when installed, and can solve the technical difficulties existing in the above background, and has the advantages of fewer parts, simple structure, convenient installation and easy use. The technical solution of the present invention is as follows:

[0004] A door lock, comprising a first handle and a second handle for correspondingly installing on two sides of a door body, wherein the first handle is provided with:

[0005] A first contact circuit board, on which one or more first contacts are arranged;

[0006] The insulating stud is a hollow cylindrical body;

[0007] A soft conductive medium is built into the insulating stud and one end of which is in contact with the corresponding first contact;

[0008] The first handle bottom cover is fixed on the first handle, and the insulating stud is inserted into the first handle bottom cover.

[0009] The second handle is provided with:

[0010] A second contact circuit board, on which one or more second contacts are arranged;

[0011] A through-through conductive fixing screw, made of conductive material, one end of which contacts the corresponding second contact point;

[0012] The second handle bottom cover is fixed on the second handle, and the through-through conductive fixing screws are inserted into the second handle bottom cover.

[0013] Wherein, when the door lock is in an installed state, the other end of the soft conductive medium is in conductive contact with the other end of the conductive fixing screw.

[0014] Optionally, the insulating stud is made of insulating material.

[0015] Optionally, the through-going conductive fixing screw is connected to the insulating stud.

[0016] Optionally, a first threaded hole is provided on the bottom cover of the first handle, and a bottom cover fixing screw passes through the first threaded hole to fix the first handle bottom cover to the first handle, so that the insulating stud passes through the first handle bottom cover and extends toward the second handle.

[0017] Optionally, a second handle screw insulating bushing is also sleeved on the through-through conductive fixing screw, so that the through-through conductive fixing screw is insulated from the second handle bottom cover.

[0018] Optionally, a control panel is provided on one side of the first handle, and the first contact circuit board is electrically connected to the control panel via a wire.

[0019] Optionally, a battery is provided on one side of the second handle.

[0020] Optionally, the first contact and the second contact are both spring contacts.

[0021] Optionally, the soft conductive medium is a spring.

[0022] The present invention also provides a door, comprising the door lock as described above, wherein the first handle and the second handle are installed on both sides of the door.

[0023] The present invention has the following beneficial effects:

[0024] (1) Through the conductive connection between the soft conductive medium embedded in the insulating stud and the conductive fixing screw, the electrical signal or current of the first handle is transmitted to the second handle without adding an additional wiring interface;

[0025] (2) Since there is no need to process the docking line interface on the first handle and the second handle, the processing complexity is reduced;

[0026] (3) Since there is no need to connect the wires to the wiring interface during installation, the installation is convenient and quick, which improves the installation efficiency.

[0027] (4) Moreover, the insulating stud connected to the through-conductive fixing screw is cleverly used as an insulating layer, thereby reducing the conventional problem of separately setting the force-bearing connecting member between the first handle and the second handle and its insulating sleeve, resulting in a large number of parts and the defect that the outer insulating layer is easily damaged during the assembly process, resulting in a short circuit.

[0028] (5) By adopting the conductive contact between the soft conductive medium and the through-conductive fixing screws, when adjusting the screwing degree of the through-conductive fixing screws and the insulating studs according to the thickness of the door body, the soft conductive medium can be squeezed by the through-conductive fixing screws to conveniently adapt to the thickness of the door body. In addition, due to the compressibility of the soft conductive medium, compared with the use of hard contact conductive connection, the present application can adapt to a larger range of door body thickness and is also convenient to adjust.

Figures 1 to 4 To explain the door lock. It should be noted that the first handle in the following text refers to the handle set on the outdoor side of the door, and the second handle refers to the handle set on the indoor side of the door. The indoor and outdoor are only relative. For example, for a house door, the door facing the inside of the house is indoor, and the door facing the outside of the house is outdoor. For example, for a bedroom door, it also has indoor and outdoor. The door facing the inside of the bedroom is considered indoor, and the door facing the outside of the bedroom is considered outdoor.

[0036] like Figure 1 As shown, the door lock includes a first handle 1, a first contact circuit board 2 installed on the first handle 1, two soft conductive media 3, two insulating studs 6, a first handle bottom cover 7, two bottom cover fixing screws 8, a second handle 12 and a second handle bottom cover 10 installed on the second handle 12, and two through-conductive fixing screws 11.

[0037] The first handle 1 includes a first column portion 20 and an extended first handle portion 41. A first contact circuit board 2 is disposed on the second handle side of the first column portion 20. Figure 1 As shown, the first contact circuit board 2 is semicircular, which is suitable for the internal structure of the column part 20, and the first contact circuit board 2 is fixed on the first column part 20 through the through hole on the first contact circuit board 2 and the protrusion on the column part 20. Two first contacts 21 are also provided on the first contact circuit board 2, and the two first contacts 21 can be a positive contact and a negative contact respectively.

[0038] The first handle bottom cover 7 has a first through hole 72 for the insulating stud 6 to pass through. Figure 1 The two horizontal ones are first through holes 72. The square core 50 passes through the center of the first handle bottom cover 7 and extends to the second handle side. The insulating studs 6 are all hollow cylindrical bodies. A first threaded hole 71 is also provided on the first handle bottom cover 7. The bottom cover fixing screw 8 passes through the first threaded hole 71 to fix the first handle bottom cover 7 on the column part 20 of the first handle 1, so that the insulating studs 6 pass through the first handle bottom cover 7 and extend to the second handle side. The insulating studs 6 are made of insulating material, such as plastic. The soft conductive medium 3 is built into the insulating studs 6, and the soft conductive medium 3 can be a spring. The first handle sides of the two soft conductive media 33 are respectively in contact with the corresponding first contacts 21, so that the first contacts 21 of the first contact circuit board 2 are in conductive connection with the soft conductive medium 3, and the soft conductive medium 3 is insulated from the first handle bottom cover.

[0039] The structure of the second handle 12 is described below. The second handle 12 includes a second column portion 30 and a second handle portion 31. The second column portion 30 is provided with a second contact circuit board 13. Figure 1 As shown, the second contact circuit board 13 is semicircular, which is suitable for the internal structure of the second column part 30, and the second contact circuit board 13 is fixed on the second column part 30 through the through hole on the second contact circuit board 13 and the protrusion on the second column part 30. Two second contacts are also provided on the second contact circuit board 13, and the two second contacts are respectively a positive contact and a negative contact.

[0040] The second handle bottom cover 10 has two second through holes 102 for the conductive fixing screws 11 to pass through. Figure 1 The two horizontal ones are second through holes 102. The through conductive fixing screw 11 passes through the corresponding second through holes 102 on the second handle bottom cover 10 and extends toward the first handle side. The second handle bottom cover 10 is fixed to the first handle side of the second column portion 30. The second handle side of the through conductive fixing screw 11 is in conductive contact with the two second contacts on the second contact circuit board 13 respectively, and the first handle side of the through conductive fixing screw 11 is used to be inserted into the insulating stud 6, and the through conductive fixing screw can be screwed into the insulating stud for fixed installation. The through conductive fixing screw 11 is made of conductive material and is in conductive contact with the soft conductive medium 3. In this way, the first contact 21 of the first contact circuit board 2, the soft conductive medium 3, the through conductive fixing screw 11, and the second contact of the second contact circuit board 13 can be kept in conductive connection in sequence.

[0041] Preferably, each through-through conductive fixing screw 11 is also provided with a second handle screw insulating bushing 9, and the second handle screw insulating bushing 9 extends to the second through hole 102, so that the outer periphery of the through-through conductive fixing screw 11 will not contact the second handle bottom cover 10, thereby ensuring that the second handle side of the through-through conductive fixing screw 11 can be conductively connected to the second contact, and the first handle side can be conductively connected to the soft conductive medium 3, while always being insulated from the second handle bottom cover 10.

[0042] Through the above structure, the first handle 1 is installed on the side outside the door, and the second handle 12 is installed on the side inside the door, and after installation, the through-conductive fixing screw 11 of the second handle 12 is always in contact with the soft conductive medium 3, so that the second contact circuit board 13 of the second handle 12 is conductively connected with the first contact circuit board 2 of the first handle. The first contact circuit board 2 of the first handle 1 can be connected to the control panel outside the door through a wire circuit to transmit an electrical signal or current for operating the control panel, so that the electrical signal or current of the first handle is transmitted to the second contact circuit board 13 of the second handle 12 through the soft conductive medium 3 and the through-conductive fixing screw 11. Specifically, the first contact circuit board 2 of the first handle transmits the current to the second contact circuit board 13 of the second handle through the soft conductive medium 3 and the through-conductive fixing screw 11 in contact therewith, and forms a loop to the first contact circuit board 2 of the first handle through another soft conductive medium 3 and the through-conductive fixing screw 11 in contact therewith.

[0043] In an optional embodiment, the first contact 21 of the first contact circuit board 2 and the second contact on the second contact circuit board 13 are both spring contacts, which can maintain a good contact force and good conductive contact through the elastic force of the spring.

[0044] The present invention also provides a door, comprising the door lock as described above, wherein the first handle is installed on the outdoor side of the door body, and the second handle is installed on the indoor side of the door body.

[0046] Furthermore, a battery is provided on one side of the door body where the second handle is installed.

[0047] It should be noted that, although the above description is based on the first contact circuit board and the second contact circuit board having two contacts respectively, the present embodiment does not limit the number of contacts, as long as there is more than one contact. For example, three contacts may be provided on the first contact circuit board, two of which are used for conductive contact with the soft conductive medium 3, and the other contact is used for other control wiring, or all three contacts are respectively in conductive contact with the corresponding soft conductive medium 3, which is all possible.
