Description

Technical Field

[0001] This utility model belongs to the field of smart lock technology, specifically relating to a fixed sealing plate structure for a smart lock. Background Technology

[0002] A door lock is a mechanical tool used to lock and secure a door. With the continuous development of technology, smart door locks have emerged in various types, including fingerprint locks, facial recognition locks, and password locks. During the installation of smart door locks, a fixing plate is installed to ensure the stability of the connection between the smart lock and the door. This fixing plate uses bolts and fits into through holes in the door to tightly fit the two parts of the smart lock to both sides of the door. The fixing plate is a commonly used component in the installation of smart locks.

[0003] Chinese utility model patent CN210563807U discloses a fixed sealing plate structure for a smart lock, including a first lock body, a second lock body, and screws. A first sealing plate is provided at the end of the first lock body, and a second sealing plate is provided at the end of the second lock body. The first and second sealing plates are respectively attached to the two sides of the door. A first strip-shaped through hole is provided on the first sealing plate, and a second strip-shaped through hole is provided on the second sealing plate. The first and second strip-shaped through holes are positioned opposite each other, and a screw is provided between the first and second strip-shaped through holes.

[0004] The aforementioned fixed sealing plate structure, through the establishment of two sets of strip-shaped through holes, allows the screws to slide up and down within the through holes, changing the screw installation position. This facilitates the screws' connection and mating with the through holes on the door, eliminating the need for additional corresponding slots on the door. While this method is stable, in actual use, after the sealing plate is attached to the door, although the strip-shaped through holes allow the screws to align, the sealing plate slides downwards due to the presence of the strip-shaped through holes and gravity during the screw alignment process. This causes the sealing plate, which was originally attached to the predetermined position on the door, to become misaligned, affecting the overall installation efficiency of the smart lock itself. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problems mentioned in the background section, the present invention adopts the following technical solution.

[0007] A fixed sealing plate structure for a smart lock includes a first sealing plate and a second sealing plate. Both the first and second sealing plates are sealing plates of the smart lock. The first and second sealing plates are respectively attached to the two sides of the door. A lock cylinder is provided between the first and second sealing plates. A pressing assembly is provided between the first and second sealing plates. The pressing assembly is provided with a pressing screw for locking the position of the first and second sealing plates and a limiting member to prevent the first and second sealing plates from misaligning when the pressing screw is engaged.

[0008] As a preferred embodiment of this utility model, the extrusion assembly includes an extrusion screw, a guide groove, a threaded cylinder, and an extrusion end. Guide grooves are provided on the side walls of both the first and second sealing plates. The extrusion screw is slidably installed in the guide groove of the first sealing plate, and the threaded cylinder is slidably installed in the guide groove of the second sealing plate. An extrusion end is installed at the end of the threaded cylinder, and the threaded cylinder is threadedly connected to the extrusion screw. Limiting members for locking the position of the extrusion screw are installed on the side walls of the first and second sealing plates.

[0009] As a preferred technical solution of this utility model, the limiting member includes a locking block, a spring assembly, and a push plate. A sliding groove is provided on the side wall of the first sealing plate and the second sealing plate. The locking block is slidably installed in the sliding groove. The end of the locking block enters the guide groove. A spring assembly is installed at the end of the locking block. One end of the spring assembly is connected to the inner wall of the sliding groove. A push plate is installed on the side wall of the locking block to push the position of the locking block.

[0010] As a preferred technical solution of this utility model, one side of the end of the locking block is an inclined surface, and the other side of the end of the locking block is a plane.

[0011] As a preferred technical solution of this utility model, the limiting component includes a sleeve, a guide plate and a plug rod. The sleeve is sleeved on the outside of the extrusion screw and the end of the threaded cylinder. The guide plate is symmetrically installed on the side of the sleeve. The guide plate slides in the guide groove with the sleeve. The plug rod is symmetrically installed on the side wall of the sleeve. The first sealing plate and the second sealing plate have equidistant mating grooves on their side walls for mating with the plug rod.

[0012] As a preferred technical solution of this utility model, the second sealing plate includes a sealing plate body and a limiting frame. The sealing plate body is disposed on the side wall of the door and on the side opposite to the first sealing plate. The limiting frame is symmetrically installed on the sealing plate body, and the limiting frame limits the end angle of the extrusion end in the guide groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention, through the establishment of an extrusion assembly and first and second sealing plates, enables rapid installation of the two sets of sealing plates. It also allows for adjustment of the extrusion screw's position and height based on the door's slot, eliminating the need for additional slots on the door to connect the extrusion screw and threaded cylinder. This simplifies the installation method for fixing the sealing plates. Furthermore, the limiting component in this invention includes a locking block and a spring assembly. These components allow the extrusion screw to slide stably within the guide groove and lock the bottom position of the extrusion screw. When the rod is connected to the threaded cylinder, the locking block fits against the outer wall of the extrusion screw, supporting the fixed sealing plate and preventing it from slipping. The limiting component in this invention includes a sleeve and a connecting rod. After the extrusion screw and the threaded cylinder are aligned but before they are connected, the sleeve is pressed to allow the connecting rod to enter the mating groove, locking the relative positions of the extrusion screw and the fixed sealing plate. This prevents the fixed sealing plate from slipping downwards when the extrusion screw is connected to the threaded cylinder, thus achieving stable installation of the fixed sealing plate and ensuring the effectiveness of the smart lock.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0025] Example 1:

[0026] like Figure 1 and Figure 2 As shown, this is a structural diagram of the fixed sealing plate structure of the smart lock in this embodiment. The fixed sealing plate structure of the smart lock in this embodiment can quickly adjust the position of the screw according to the position of the door slot. When the screw locks the two sets of fixed sealing plates, it can prevent the screw from being misaligned. The fixed sealing plate structure includes a first sealing plate 1, a second sealing plate 2, and a pressing component 3. The first sealing plate 1 and the second sealing plate 2 are two sets of sealing plates of the smart lock. The first sealing plate 1 and the second sealing plate 2 are respectively attached to the two sides of the door. A pressing component 3 is provided between the first sealing plate 1 and the second sealing plate 2. The pressing component 3 reduces the distance between the first sealing plate 1 and 2, so that the first sealing plate 1 and the second sealing plate 2 press against the door at the same time, thereby locking and installing the positions of the first sealing plate 1 and the second sealing plate 2.

[0027] A door lock cylinder is provided between the first sealing plate 1 and the second sealing plate 2. The door lock cylinder is installed inside the door, and both the first sealing plate 1 and the second sealing plate 2 are equipped with smart locks. The smart locks cover the surface structure of the first sealing plate 1 and the second sealing plate 2. The smart locks are directly connected to the first sealing plate 1 or the second sealing plate 2 by screws.

[0028] As attached Figure 3 and Figure 4The diagram shows the structure of the extrusion assembly 3 in this embodiment. The extrusion assembly 3 includes an extrusion screw 31, a guide groove 32, and a threaded cylinder 33. Guide grooves 32 are provided on both the first sealing plate 1 and the second sealing plate 2, and the guide grooves 32 are positioned opposite each other. The extrusion screw 31 is slidably installed between the two sets of guide grooves 32. A threaded cylinder 33 is threadedly installed at the end of the extrusion screw 31. The threaded cylinder 33 passes through the guide groove 32 and enters between the first sealing plate 1 and the second sealing plate 2. An extrusion end 34 is installed at the end of the threaded cylinder 33, and the extrusion end 34 is fitted against the side wall of the second sealing plate 2. In use, the extrusion screw 31 is inserted into the guide groove 32 in the first sealing plate 1, and then the extrusion end 34 is inserted into the guide groove 32 in the second sealing plate 2. The extrusion is adjusted according to the position of the door's slot. The positions and heights of the extrusion screw 31 and the extrusion end 34 are adjusted vertically to allow them to accurately enter the slots on the door. The extrusion screw 31 is rotated so that its end enters the threaded cylinder 33, where they engage. The distance between the ends of the extrusion screw 31 and the extrusion end 34 is adjusted so that the end of the extrusion screw 31 presses against the side wall of the first sealing plate 1, and the end of the extrusion end 34 presses against the side wall of the second sealing plate 2, thus achieving the compression of the positions of the first sealing plate 1 and the second sealing plate 2. This allows the first sealing plate 1 and the second sealing plate 2 to be stably attached to both sides of the door. A limiting member 35 is installed on the side wall of the first sealing plate 1 to lock the position of either the first sealing plate 1 or the second sealing plate 2 when the extrusion screw 31 engages with the threaded cylinder 33.

[0029] It is worth noting that the extrusion end 34 has a hexagonal structure, and the radii of both the end component of the extrusion end 34 and the end component of the extrusion screw 31 are larger than the width of the guide groove 32. Neither the end of the extrusion end 34 nor the end of the extrusion screw 31 can penetrate the guide groove 32 to enter between the first sealing plate 1 and the second sealing plate 2.

[0030] As attached Figure 5As shown, this is a schematic diagram of the limiting member 35 in this embodiment. The limiting member 35 includes a locking block 351, a spring assembly 352, and a push plate 353. Sliding grooves are formed on the side walls of the first sealing plate 1 and the second sealing plate 2. The locking block 351 is equidistantly slidably installed in the sliding grooves. The end of the locking block 351 enters the guide groove 32. The spring assembly 352 is installed at the end of the locking block 351, and the other end of the spring assembly 352 is connected to the side wall of the sliding groove. The push plate 353 is installed on the side of the locking block 351. When the extrusion screw 31 slides in the guide groove 32, the operator... Pressing down on the first sealing plate 1 ensures that the first sealing plate 1 is locked in place. When the extrusion screw 31 is moved, the inclined surface of the locking block 351 is compressed and retracts into the moving groove, allowing the spring assembly 352 to enter the storage state. After the extrusion screw 31 is no longer in contact with the locking block 351, the locking block 351 pops out under the action of the spring assembly 352, limiting the movement space of the extrusion screw 31 and preventing the first sealing plate 1 or the second sealing plate 2 from being misaligned or sliding downwards when the extrusion screw 31 is docked with the threaded cylinder 33.

[0031] As attached Figure 7 As shown, this is a structural schematic diagram of the second sealing plate 2 in this embodiment. The second sealing plate 2 includes a sealing plate body 21 and a limiting frame 22. The overall structure of the sealing plate body 21 is the same as that of the first sealing plate 1. The sealing plate body 21 is located on the opposite side of the first sealing plate 1. The limiting frames 22 are symmetrically fixedly installed on the side wall of the sealing plate body 21. The limiting frames 22 are located on both sides of the guide groove 32. The establishment of the two sets of limiting frames 22 locks the end angle of the extrusion end 34 and prevents the extrusion end 34 from spinning freely.

[0032] Example 2:

[0033] As attached Figure 6 As shown, this is a structural schematic diagram of the limiting member 35 in this embodiment. The difference between this embodiment and Embodiment 1 is that the limiting member 35 includes a sleeve 354, a guide plate 355, and a connecting rod 356. The sleeve 354 is respectively sleeved on the outside of the extrusion screw 31 and the threaded cylinder 33. The guide plate 355 is symmetrically installed on the side of the sleeve 354 and slides in the guide groove 32. The connecting rod 356 is symmetrically installed on the side wall of the sleeve 354, and the first sealing plate 1 has equally spaced mating grooves for mating with the connecting rod 356. After the extrusion screw 31 and the threaded cylinder 33 are aligned and before they are docked, the sleeve 354 is extruded, so that the insertion rod 356 is inserted into the docking groove. At this time, the sleeve 354 is locked, and the extrusion screw 31 rotating inside the sleeve 354 is locked relative to the first sealing plate 1, and the threaded cylinder 33 is locked relative to the second sealing plate 2. This facilitates the stable docking of the extrusion screw 31 and the threaded cylinder 33 and prevents the first sealing plate 1 or the second sealing plate 2 from slipping when the extrusion screw 31 docks with the threaded cylinder 33.

[0034] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
