[0001] This utility model belongs to the field of door lock technology, specifically relating to a door lock with a reverse mounting structure. Background Technology
[0002] With the rapid development of smart lock technology, more and more lock products are adopting electronic control to achieve locking and unlocking functions, and are widely used in residences, office buildings, and public facilities. Traditional smart locks typically integrate the control circuit board, clutch assembly, and lock mechanism onto the lock's mounting base, encapsulated by the fit of the front and rear housings. However, this structure has revealed numerous problems during actual assembly and subsequent maintenance.
[0003] In traditional door lock structures, all core components are concentrated in the mounting base plate, resulting in a compact internal layout, complex wiring, and susceptibility to interference or component obstruction, affecting the stability and reliability of the lock. Secondly, this structure requires the circuit board, clutch mechanism, and lock body components to be fixed separately to different areas of the base plate during assembly, making the assembly process cumbersome, positioning difficult, and resulting in low manual assembly efficiency, high error rates, and hindering mass production. During maintenance and replacement, if the electronic control components or the entire lock needs to be replaced, the mounting base plate must be disassembled first, complicating the operation and increasing maintenance time and costs.
[0004] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: a door lock with a reverse mounting structure, comprising a mounting base plate and a mounting front cover. The mounting front cover is mounted on the front of the mounting base plate. The inner surface of the mounting front cover is provided with a clutch mounting position and a circuit board mounting position. The circuit board mounting position is located above the clutch mounting position. A clutch assembly is installed in the clutch mounting position. A control circuit board is installed in the circuit board mounting position. A mounting bracket is provided on one end surface of the clutch assembly. A lock assembly mounting position is provided at the lower end of the mounting bracket. A lock assembly component is installed on the lock assembly mounting position.
[0007] Furthermore, the surface edge of the mounting bracket is provided with a plurality of first mounting through holes, the edge of the clutch assembly is provided with a plurality of mounting through grooves, and the surface edge of the mounting base plate is provided with a plurality of second mounting through holes. The plurality of second mounting through holes, the plurality of mounting through grooves, and the plurality of first mounting through holes correspond one to one. Fasteners are sequentially passed through the second mounting through holes, the mounting through grooves, and the first mounting through holes to connect and fix them, thereby fixing the clutch assembly in the clutch mounting position.
[0008] Furthermore, the circuit board mounting position is provided with symmetrical fixing buckles on both sides, and the control circuit board is provided with symmetrical fixing edges on both sides to cooperate with it. The fixing edges and the fixing buckles engage with each other to fix the control circuit board in the circuit board mounting position.
[0009] Furthermore, a first connecting hole is provided on one side of the lock mounting position, and a second connecting hole is provided on one side of the lock component. The first connecting hole and the second connecting hole correspond to each other, and are connected and fixed by fasteners passing through the second connecting hole and the first connecting hole, thereby fixing the lock component in the lower end of the mounting front cover.
[0010] Furthermore, the bottom of the mounting cover has a lock opening, and the lock component is correspondingly positioned with respect to the lock opening.
[0011] Furthermore, the clutch assembly has a clutch connecting rod in the middle, and a connecting opening is provided in the middle of the clutch mounting position. The clutch connecting rod extends through the connecting opening to the outside of the mounting front cover, and a door lock handle is connected to the outside of the clutch connecting rod.
[0012] Furthermore, the mounting base plate has several fixing holes symmetrically opened on both sides of its surface, and the mounting front cover has several fixing posts symmetrically opened on both sides of its inner surface. The fixing holes and fixing posts correspond one-to-one, and are connected and fixed by fasteners passing through the fixing holes and fixing posts, so that the mounting front cover is fixedly installed on the front end of the mounting base plate.
[0013] This utility model has the following advantages: The inner surface of the mounting cover is provided with a clutch mounting position and a circuit board mounting position. The circuit board mounting position is located above the clutch mounting position, where a clutch assembly is installed. A control circuit board is also installed in the circuit board mounting position. One end of the clutch assembly has a mounting bracket, and the lower end of the mounting bracket has a lock mounting position where a lock assembly is installed. This utility model's reverse-mounted door lock integrates the clutch assembly, control circuit board, and lock assembly into the mounting cover, replacing the traditional layout where they are centrally mounted on the mounting base. This results in a more compact and easier-to-assemble reverse-mounted door lock.

Detailed Implementation
[0018] like Figures 1 to 3As shown, a door lock with a reverse-mounted structure includes a mounting base plate 10 and a mounting front cover 20. The mounting front cover 20 covers the front of the mounting base plate 10. The inner surface of the mounting front cover 20 has a clutch mounting position 21 and a circuit board mounting position 22, with the circuit board mounting position 22 located above the clutch mounting position 21. A clutch assembly 30 is installed in the clutch mounting position 21 for controlling the locking and unlocking actions of the lock body. A control circuit board 40 is installed in the circuit board mounting position 22 for implementing electronic control functions such as signal recognition and control drive. Thus, the clutch assembly 30 and the control circuit board 40 are respectively installed in the mounting front cover 20, achieving a reverse-mounted layout of the internal functional components of the door lock. Compared with the prior art where all components are centrally installed inside the mounting base plate, this invention integrates the clutch assembly 30 and the control circuit board 40 within the mounting front cover 20, making the door lock structure more compact, simplifying the assembly steps, effectively improving production efficiency, reducing assembly difficulty, and facilitating later maintenance and repair.
[0019] In practical implementation, one end surface of the clutch assembly 30 is provided with a mounting bracket 50. The surface edge of the mounting bracket 50 has several first mounting holes 51, and the edge of the clutch assembly 30 has several mounting grooves 31. Correspondingly, the surface edge of the mounting base plate 10 also has several second mounting holes 11. These second mounting holes 11, mounting grooves 31, and first mounting holes 51 correspond one-to-one. During assembly, fasteners are sequentially passed through the second mounting holes 11, mounting grooves 31, and first mounting holes 51 for connection and fixation, thereby ensuring the clutch assembly 30 is securely installed in the clutch mounting position 21. With the above structural design, the installation method is simple and convenient, requiring no special tools or complex operations. The multi-point fixing method improves the stability of the component installation and effectively prevents loosening due to vibration or rotation during use.
[0020] In practical implementation, the circuit board mounting position 22 is symmetrically provided with fixing buckles 221 on both sides, and the control circuit board 40 is symmetrically provided with fixing edges 41 on both sides to cooperate with it. During installation, when the control circuit board 40 is embedded in the circuit board mounting position 22, the fixing edges 41 and the fixing buckles 221 engage and cooperate to fix the control circuit board 40 in the circuit board mounting position 22. With the above structural design, the structure is simple. Through the mutual cooperation of the buckles and the edges, no additional screws or adhesives are required for fasteners, making assembly convenient and enabling quick installation and disassembly, thus improving production assembly efficiency.
[0021] In practical implementation, the lower end of the mounting bracket 50 is provided with a lock mounting position 52, on which a lock component 60 is mounted. A first connecting hole 521 is provided on one side of the lock mounting position 52, and a second connecting hole 61 is provided on one side of the lock component 60. The first connecting hole 521 and the second connecting hole 61 correspond to each other and are connected and fixed to the first connecting hole 521 by fasteners passing through the second connecting hole 61. This allows the lock component 60 to be fixedly installed in the lower end of the mounting front cover 20. A lock opening 23 is provided at the bottom of the mounting front cover 20, and the lock component 60 is correspondingly positioned with the lock opening 23, enabling functional communication between the internal lock component 60 and the external actuator. Through the above structural design, the lock component 60 has a clear positioning and is easy to assemble, which is conducive to standardized production.
[0022] In practical implementation, the clutch assembly 30 has a clutch connecting rod 32 in the middle, and the clutch mounting position 21 has a connecting opening 211 in the middle. The clutch connecting rod 32 extends through the connecting opening 211 to the outside of the mounting front cover 20. A door lock handle 70 is connected to the outside of the clutch connecting rod 32, and the door lock handle 70 can rotate around the axis of the clutch connecting rod 32. During use, rotating the door lock handle 70 drives the clutch connecting rod 32 to rotate synchronously. The rotation of the clutch connecting rod 32 drives the mechanical mechanism inside the clutch assembly 30 to perform the locking or unlocking function of the lock body, thereby completing the opening and closing control of the door lock.
[0023] In practical implementation, a number of fixing holes 12 are symmetrically opened on both sides of the surface of the mounting base plate 10, and a number of fixing posts 24 are symmetrically opened on both sides of the inner side of the mounting front cover 20. The fixing holes 12 and the fixing posts 24 correspond one-to-one, and are connected and fixed by fasteners passing through the fixing holes 12 and the fixing posts 24, so that the mounting front cover 20 is fixedly installed on the front end of the mounting base plate 10. This structure is simple in design, easy to install and operate, and convenient for product assembly and maintenance.
[0024] In summary, the inner surface of the mounting cover 20 is provided with a clutch mounting position 21 and a circuit board mounting position 22. The circuit board mounting position 22 is located above the clutch mounting position 21. A clutch assembly 30 is installed in the clutch mounting position 21, and a control circuit board 40 is installed in the circuit board mounting position 22. A mounting bracket 50 is provided on one end of the clutch assembly 30, and a lock mounting position 52 is provided at the lower end of the mounting bracket 50. A lock assembly 60 is installed on the lock mounting position 52. This utility model's reverse-mounted door lock integrates the clutch assembly, control circuit board, and lock assembly, among other core components, into the mounting cover, replacing the traditional layout where they are centrally mounted on the mounting base plate. This results in a more compact and easier-to-assemble reverse-mounted door lock. This structure not only improves assembly efficiency and reduces manufacturing and maintenance costs but also facilitates later repairs and upgrades.
