Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically to an anti-pinch smart lock. Background Technology

[0002] Electronic smart locks, also known as smart home locks or smart locks, are an important part of modern security technology. Unlike traditional mechanical locks, smart locks control the opening and closing status of the lock electronically and can be equipped with various high-tech functions, such as biometrics and remote control, providing a more convenient and secure access control experience for homes, offices and other places.

[0003] The door lock panel of a smart door lock is an important component installed on the door to control the opening and closing of the door lock. It usually contains some user operation buttons or modules so that users can operate the door lock by pressing or rotating. Common types of door lock panels include mechanical door lock panels, electronic door lock panels and smart door lock panels.

[0004] Currently, after the door lock panel is matched with the door, there is a certain gap between the handle on the surface of the door lock panel and the door lock panel. This design is mainly to make it easier for users to hold the handle for fingerprint unlocking. Although this design meets the main needs of users, in some special cases, users may hold the handle with incorrect gestures or postures, especially during the opening and closing of the door. Such incorrect actions may cause hand injuries, posing certain safety hazards.

[0005] In view of this, the present invention proposes an anti-pinch smart lock to solve the above-mentioned technical problems. Utility Model Content

[0006] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for an anti-pinch smart lock. Firstly, it achieves targeted protection through a single-sided and double-sided hand-stop structure. The hand-stop plate a in the single-sided structure and the hand-stop plate b in the double-sided structure utilize rectangular structures and rounded corners to physically limit and guide the user's hand, correcting incorrect grip postures and preventing the hand from approaching the door gap. The double-sided hand-stop structure comprehensively regulates hand movements from both sides, providing more comprehensive protection than the single-sided structure, significantly reducing the risk of pinching injuries to special groups (such as children and the elderly) due to improper operation, filling a gap in the safety details of existing designs. Secondly, the single-sided and double-sided hand-stop structures can be flexibly switched according to the scenario; users can choose single-sided protection or full protection based on their usage habits or protection needs, enhancing the adaptability of the structure.

[0007] This utility model provides the following technical solution: an anti-pinch smart lock, including a panel and a handle fixedly connected to the surface of the panel;

[0008] The outer surface of the handle is slidably connected with a single-sided hand stop structure and a double-sided hand stop structure;

[0009] The single-sided hand stop structure includes a sliding sleeve a that is slidably connected to the outer surface of the handle, and a hand stop piece a is fixedly connected to one side of the sliding sleeve a;

[0010] The double-sided hand stop structure includes a sliding sleeve b that is slidably connected to the outer surface of the handle, and hand stop pieces b are symmetrically connected to both sides of the sliding sleeve b;

[0011] The surface of the panel has multiple mounting holes, and the inner cavity of the mounting holes has a connection structure for connecting the panel to the door.

[0012] As a preferred technical solution of this utility model, the connection structure includes two guide grooves symmetrically through one end of the mounting hole, a rotating shaft is rotatably connected to the inner cavity of the mounting hole, a baffle is fixedly connected to one end of the rotating shaft, a hexagonal groove is provided at the end of the baffle away from the rotating shaft, two extrusion plates are symmetrically fixedly connected to the bottom of the surface of the rotating shaft, and a limiting structure for restricting its rotation is provided on the surface of the rotating shaft.

[0013] As a preferred technical solution of this utility model, the limiting structure includes multiple protrusions fixedly connected to one end of the mounting hole, a limiting piece fixedly connected to the surface of the rotating shaft, multiple grooves being provided at the end of the limiting piece facing the protrusions, and a compression spring being provided between the limiting piece and the baffle.

[0014] As a preferred technical solution of this utility model, a rubber pad is fixedly connected to the end of each extrusion plate away from the rotation axis, and the outer surface of the rubber pad is provided with anti-slip texture, which is a concave structure.

[0015] As a preferred embodiment of this utility model, the protrusions and the grooves are arranged in a circular array, and the shape and size of the protrusions and the grooves are adapted to each other.

[0016] In a preferred embodiment of this utility model, the compression spring is sleeved on the surface of the rotating shaft, one end of the compression spring is fixedly connected to the other end of the limiting piece, and the other end of the compression spring abuts against the baffle.

[0017] As a preferred embodiment of this utility model, both the hand stop plate a and the hand stop plate b are rectangular structures, and their edges are rounded.

[0018] In a preferred embodiment of this utility model, the hand stop a and hand stop b are respectively plastic hand stop a and plastic hand stop b.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Addressing the issue in existing technologies where a gap exists between the handle and the door lock panel, leading to potential hand pinching injuries due to incorrect hand gestures when opening and closing the door, this structure provides targeted protection through a single-sided and double-sided hand stop structure. The single-sided hand stop (a) and the double-sided hand stop (b) utilize rectangular structures and rounded corners to physically limit and guide the user's hand, correcting incorrect grip postures and preventing the hand from approaching the panel gap. The double-sided hand stop structure comprehensively regulates hand movements from both sides, providing more comprehensive protection than the single-sided structure. This significantly reduces the risk of pinching injuries to vulnerable groups (such as children and the elderly) due to improper operation, filling a gap in safety details in existing designs.

[0021] 2. The single-sided and double-sided handstop structure of this utility model can be flexibly switched according to the scenario. Users can choose single-sided protection or full protection according to their usage habits or protection needs, which enhances the adaptability of the structure.

[0022] 3. The connection structure of this utility model adopts a quick fixing method of "extrusion, rotation, and rebound". During installation, the extrusion plate only needs to be passed through the guide groove, and the tool is used to squeeze the baffle to make the rotating shaft drive the extrusion plate into the door body. After rotating 90 degrees, the spring rebounds to achieve automatic locking, without the need to repeatedly tighten the bolts. During disassembly, the baffle only needs to be squeezed and rotated in the opposite direction to unlock. No complicated tools are required throughout the process, which greatly shortens the installation and maintenance time, and is especially suitable for scenarios where panels are frequently replaced or repaired.

[0023] 4. The groove of the limiting plate and the protrusion of the mounting hole of this utility model are engaged under the action of the compression spring, which effectively restricts the rotation of the rotating shaft and avoids the extrusion plate from accidentally resetting.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-7 As shown, an anti-pinch smart lock includes a panel 1 and a handle 101 fixedly connected to the surface of the panel 1.

[0034] The outer surface of the handle 101 is slidably connected with a single-sided hand stop structure and a double-sided hand stop structure;

[0035] The single-sided hand stop structure includes a sliding sleeve a2 that is slidably connected to the outer surface of the handle 101, and a hand stop piece a201 is fixedly connected to one side of the sliding sleeve a2;

[0036] The double-sided hand stop structure includes a sliding sleeve b3 that is slidably connected to the outer surface of the handle 101, and hand stop pieces b301 are symmetrically connected to both sides of the sliding sleeve b3;

[0037] The surface of panel 1 is provided with multiple mounting holes 4, and the inner cavity of the mounting holes 4 is provided with a connection structure for connecting panel 1 to the door;

[0038] The connecting structure includes two guide grooves 5 symmetrically through one end of the mounting hole 4. A rotating shaft 501 is rotatably connected to the inner cavity of the mounting hole 4. A baffle 502 is fixedly connected to one end of the rotating shaft 501. A hexagonal groove 503 is provided at the end of the baffle 502 away from the rotating shaft 501. Two pressing plates 504 are symmetrically fixedly connected to the bottom of the surface of the rotating shaft 501. A limiting structure for restricting its rotation is provided on the surface of the rotating shaft 501.

[0039] The limiting structure includes multiple protrusions 6 fixedly connected to one end of the mounting hole 4, a limiting piece 601 fixedly connected to the surface of the rotating shaft 501, multiple grooves 602 opened at one end of the limiting piece 601 facing the protrusions 6, and a compression spring 603 provided between the limiting piece 601 and the baffle 502.

[0040] Each extrusion plate 504 has a rubber pad 7 fixedly connected to the end away from the rotating shaft 501. The outer surface of the rubber pad 7 is provided with anti-slip texture, which is a concave structure.

[0041] Both the protrusions 6 and the grooves 602 are arranged in a ring array, and the shapes and sizes of the protrusions 6 and the grooves 602 are compatible.

[0042] A compression spring 603 is sleeved on the surface of the rotating shaft 501. One end of the compression spring 603 is fixedly connected to the other end of the limiting piece 601, and the other end of the compression spring 603 abuts against the baffle 502.

[0043] Both the hand stop plate a201 and the hand stop plate b301 are rectangular structures, and their edges are rounded.

[0044] Hand stop plate a201 and hand stop plate b301 are plastic hand stop plate a and plastic hand stop plate b, respectively.

[0045] The working principle of the single-sided hand stop structure: The sliding sleeve a2 can slide on the outer surface of the handle 101. When the user needs to use the single-sided anti-pinch function, the sliding sleeve a2 is slid to the appropriate position. At this time, the hand stop piece a201, which is fixedly connected to the sliding sleeve a2, is in a specific position. Since the hand stop piece a201 is a rectangular structure with rounded corners, when the user performs the opening and closing operation, the hand stop piece a201 can restrict and guide the position of the user's hand, correct the user's opening and closing actions to a certain extent, and prevent the hand from getting too close to the gap of the door, thereby preventing the hand from being pinched or even injured.

[0046] The working principle of the double-sided hand stop structure: The sliding sleeve b3 can slide on the outer surface of the handle 101. When the double-sided anti-pinch function is needed, slide the sliding sleeve b3 to the appropriate position, and the hand stop pieces b301 connected symmetrically on both sides will move accordingly. The hand stop pieces b301 are also rectangular structures with rounded corners. The two hand stop pieces b301 restrict and guide the user's hands from both sides, further standardizing the user's opening and closing actions. Compared with the single-sided hand stop structure, it can more comprehensively prevent the user from pinching or even getting injured due to improper actions during operation.

[0047] The working principle of the connection structure is as follows: When installing panel 1, firstly, the pressing plate 504 is passed through the guide groove 5, so that the rotating shaft 501 is located in the mounting hole 4. Using a tool, the baffle 502 is pressed through the hexagonal groove 503, causing the rotating shaft 501 to move the pressing plate 504 into the interior of the door body. Simultaneously, the compression spring 603 is compressed. Next, the rotating shaft 501 rotates, and the pressing plate 504 on its surface rotates 90 degrees accordingly. After the pressing plate 504 has rotated 90 degrees, the baffle 502 is released. At this time, the compression spring 603 extends, causing the rotating shaft 501 to retract. The rubber pad 7 at the end of the pressing plate 504 makes tight contact with the mounting position on the door body. The concave anti-slip texture on the surface of the rubber pad 7 increases friction, making the connection between the extrusion plate 504 and the door body more stable. At the same time, the groove 602 on the limiting piece 601 and the protrusion 6 at one end of the mounting hole 4 cooperate with each other. Under the elastic force of the compression spring 603, the protrusion 6 is inserted into the groove 602, restricting the rotation of the rotating shaft 501 and ensuring that the extrusion plate 504 exerts a stable extrusion force on the door body, thereby firmly installing the panel 1 on the door body. When it is necessary to remove the panel 1, the extrusion baffle 502 is squeezed and rotated 90 degrees in the opposite direction. The rotating shaft 501 drives the extrusion plate 504 to rotate in the opposite direction, so that the rubber pad 7 is no longer in contact with the installation position of the door body. Then the connecting structure can be pulled out.
