The intelligence of smart door locks provides users with certain conveniences. However, in some usage scenarios, there are still certain inconveniences. For example, during the decoration process, the installation time of smart door locks becomes a problem. If smart door locks are installed from the beginning of interior decoration, the door locks are easily damaged during the decoration process. However, if smart door locks are installed after the decoration is completed, the safety of decoration materials cannot be guaranteed. Therefore, traditional mechanical lock bodies will still be used. In addition to achieving certain security protection, they can also effectively control costs. In this application scenario, simple replacement locks are often used, and the simple replacement locks are replaced after the decoration is completed.

[0046] In order to further understand the content, features and effects of the utility model of the present application, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:
[0047] Example
[0048] At present, most of the structures of traditional simple replacement locks are integrated on the front panel, so the design difficulty of the front panel is relatively high. Although the cost is not as high as that of smart door locks, it still requires a relatively high cost. Moreover, integration on the front panel also requires more parts to cooperate, which also has a certain impact on the efficiency during subsequent assembly. In order to solve the above technical problems, this embodiment provides the following technical solutions:
[0049] For details, see Figure 1-8 , this embodiment provides a simple replacement lock, including a panel body 10, a lock core assembly and a rotary joint 40;
[0050] For details, see Figure 4 , a first through hole 11 is opened on the panel body 10;
[0051] Specifically, the lock core assembly includes a lock shell 20 and a lock core body 30 that penetrates the lock shell 20. The lock core body 30 is provided with a lock hole, and the lock core body 30 is fixedly connected to the lock shell 20 at one end away from the lock hole.
[0052] It should be noted that, see Figure 4 The spring and pin structures in the lock housing 20 are common structures of the lock core in the prior art. This application does not further describe this, but it does not mean that it does not have this part of the structure. It is just that it is a relatively mature technology in the prior art, and it is very easy for technical personnel in this field to obtain it from the existing technology. It is also not the main invention point of this application, so the spring and pin structure will not be further described.
[0053] For details, see Figure 6-7 The rotary joint 40 is rotatably connected to the lock core body 30. The rotary joint 40 is formed with a first groove 41 suitable for accommodating the end of the lock core body 30. A protrusion 42 is formed on the inner end surface of the first groove 41 along its axial direction.
[0054] Further, a locking column 31 is formed along the axial direction of the end surface of the lock core body 30 away from the lock hole, and the locking column 31 is suitable for abutting against a first point of the protrusion 42, and is suitable for abutting against a second point of the protrusion 42 after rotating around the lock core body 30 by a first angle. The lock core body 30 is suitable for driving the rotary joint 40 to rotate by acting on the protrusion 42 through the locking column 31;
[0055] When the lock core body 30 is rotated, the locking column 31 at its end will be driven to rotate. After the locking column 31 rotates from the first point position to the second point position by the first angle, it will abut against the protrusion 42. At this time, further rotation will drive the rotating joint 40 to follow the rotation. The rotation of the rotating joint 40 can realize the unlocking action. In the present embodiment, the rotating joint 40 is fixedly connected to the lock core body 30, and the structure of the protrusion 42 joint and the locking column 31 can independently use the key to open the door (outside the door) or the knob to open the door (inside the door). This structure effectively simplifies the design difficulty of the front panel of the lock, and integrates the structure that originally needs to be designed on the lock panel on the lock core, which not only effectively reduces the number of spare parts, but also effectively improves the assembly efficiency.
[0056] Specifically, a first annular groove 32 is formed around the outer peripheral wall of the lock core body 30 away from the lock hole;
[0057] Furthermore, it also includes a first snap ring 34, which is riveted to the first annular groove 32 to connect the lock core body 30 with the lock housing 20;
[0058] In the above solution, the lock core body 30 is inserted into the lock housing 20 and riveted to the first annular groove 32 through the first snap ring 34, which can effectively limit the relative movement of the lock core body 30 and the lock housing 20 along its axial direction, thereby stably realizing relative rotation. It can be understood that the riveting is a movable riveting, and the combined parts can rotate relative to each other.
[0059] For details, see Figure 5 and Figure 8 A second annular groove 33 is formed around the outer peripheral wall of the lock core body 30 at one end away from the lock hole;
[0060] Furthermore, a second through hole 43 is formed along the radial direction of the outer peripheral wall of the rotary joint 40 close to one end of the lock core body 30;
[0061] Specifically, it also includes a locking member 44 suitable for being inserted into the second through hole 43, and the locking member 44 is suitable for being locked into the second annular groove 33 to prevent the lock core body 30 from being separated from the rotary joint 40 along its axial direction;
[0062] In one embodiment, the locking member 44 may be a pin.
[0063] In the above scheme, one end of the lock core body 30 extends into the first groove 41 of the rotary joint 40, and the locking member 44 is locked into the second through hole 43 and further extends into the second annular groove 33 of the lock core body 30. At this time, the locking member 44 can limit the second annular groove 33 to restrict its axial movement along the lock core body 30, while not affecting the relative rotation movement between the lock core body 30 and the rotary joint 40.
[0064] For details, see Figure 3 The position of the first snap ring 34 is closer to the lock hole relative to the second annular groove 33 ; it can be understood that it is located between the rotary joint 40 and the lock housing 20 .
[0065] For details, see Figure 5 , a plurality of second through holes 43 are provided and distributed around the rotary joint 40;
[0066] Furthermore, the locking members 44 are provided in plurality and are arranged in one-to-one correspondence with the first through holes 11;
[0067] In the above solution, the plurality of second through holes 43 cooperate with the plurality of locking members 44 to achieve multi-point locking, thereby improving the connection stability between the lock core body 30 and the rotary joint 40 and improving the stability of the assembly of the structural parts.
[0068] For details, see Figure 7In one embodiment, the first angle is 175°-179°.
[0069] For details, see Figure 4 A mounting hole 21 is formed at one end of the lock housing 20 close to the panel body 10, and a third through hole 51 is formed on the panel body 10;
[0070] Furthermore, it also includes a fixing member 52, which is suitable for being inserted into the third through hole 51 and fixed to the mounting hole 21 to fix the lock housing 20 and the panel body 10;
[0071] In the above solution, the lock housing 20 is abutted against the surface of the panel body 10, and then the fixing member 52 passes through the third through hole 51 and is connected to the mounting hole 21. The fixing member 52 can be understood as a screw. This solution has a simple structure and is quick and easy to assemble.
[0072] It is understandable that an internal thread is formed on the inner wall of the mounting hole 21 .
[0073] For details, see Figure 4 In some embodiments, a ring-shaped extension portion 22 is formed extending from one end of the lock housing 20 close to the panel body 10, and the outer wall of the extension portion 22 is suitable for abutting against the inner wall of the first through hole 11;
[0074] In the above scheme, the lock shell 20 in this scheme is further provided with an extension portion 22, which can be inserted into the first through hole 11, so that the position of the lock shell 20 can be quickly positioned, and it also plays an auxiliary role in the positioning of other structures, which can further improve the convenience of assembly and improve the assembly efficiency.
[0075] Specifically, a sleeve 12 is provided on one side of the panel body 10 close to the lock core assembly, and the sleeve 12 is suitable for accommodating the lock core assembly;
[0076] In the above solution, the sleeve barrel is located on the outer periphery of the lock housing 20, and can position and limit the lock housing 20.
[0077] For details, see Figure 5 A second groove 45 is provided at one end of the rotary joint 40 away from the lock core body 30, and a fourth through hole 46 communicating with the second groove 45 is provided on the outer peripheral wall close to the second groove 45;
[0078] In the above scheme, the second groove 45 can be connected to the square bar, and the square bar can be inserted into the lock body to achieve unlocking and locking. The fourth through hole 46 can be used for the pin to be inserted to fix the square bar and the rotary joint 40. The structure is simple and easy to assemble.
[0079] It should be noted that the lock body structure provided in this solution is a lock body structure close to the front panel, and it needs to cooperate with other structures to complete the function of the entire lock body; but it is understandable that the other structures mentioned here are very common technologies in the prior art. Although this application does not further disclose other parts of the structure, it does not affect the understanding of those skilled in the art.
[0080] Specifically, a handle 13 is provided on one side of the panel body 10 close to the lock core assembly;
[0081] In the above solution, the handle 13 provides a better force application point for the user, thereby enabling the user to better control the opening and closing of the door.
[0082] The above description is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application are within the scope of the technical solution of the present application.
