Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically to a lock status display structure. Background Technology

[0002] Locks are typically used as locking and unlocking mechanisms for doors, such as those on building doors, vehicle doors, and outdoor structures. They are crucial for enhancing the security of doors. Furthermore, because doors are used in various scenarios, different locks are required for each scenario to meet the specific needs of each situation.

[0003] Currently, in scenarios with high privacy requirements, it's necessary to display appropriate status indicators on the outside of the door, such as "locked" or "unlocked," to prevent accidental unlocking. This allows anyone attempting to open the door to quickly ascertain the lock's status and prevents accidental opening. Additionally, some people may forget whether the door is locked when closing it, often requiring them to manually turn the handle to confirm, which is inconvenient. Therefore, the industry needs a lock with status indicators. For example, patent CN220621451U discloses a door lock cylinder cover, which has a prompt box A at the top edge of the front of the lock cylinder cover and a prompt box B at the bottom edge of the front of the lock cylinder cover. The lock cylinder is located in the center of the inside of the lock cylinder cover, and a snap lock is provided on one side of the lock cylinder. There are a total of three locks inside the lock cylinder cover: the first layer is the lock cylinder, the second layer is the barb, and the third layer is the fastener. The locking process of the first layer is to use your finger to hold the inclined surface A and lift it upward, which will make the lock cylinder protrude upward by one centimeter. At the same time, the red plate under the lock cylinder will enter the interior of the prompt box B. When you see the red plate, it means that it is locked. When you hold the inclined surface B and press it down, you can press the red plate down by one centimeter. At the same time, the green plate on top of the lock cylinder will enter the interior of the prompt box A. When you see the green plate, it means that it is not locked. This allows the user to obtain the status information of the lock in a timely manner. Although the above structure can display the lock status, the user needs to manually press the inclined surfaces A and B on the lock cylinder surface from the outside to change the display status. It only works on simple locks. For more complex locks such as household locks, it cannot be linked with the internal structure of the lock and cannot automatically change the status when the user unlocks or locks the lock, which limits its use.

[0026] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 5 The technical solution provided by this utility model is described in detail, but the following content is not intended to limit this utility model.

[0027] Figure 1 This is a structural diagram of an embodiment of the status display structure of a lock according to the present invention; Figure 2 This is a structural diagram of the lock housing of a lock with a status display structure according to this utility model. Figure 1 and Figure 2 As shown, the lock status display structure provided in this embodiment includes: a lock housing 1, a lock shaft 2, a sliding plate 3, and a toggle member 4. The lock shaft 2 is rotatably installed inside the lock housing 1, and locking and unlocking of the lock are achieved by rotating the lock shaft 2. Preferably, one end of the lock shaft 2 is connected to the lock's deadbolt knob, meaning that when the user locks or unlocks the lock using the deadbolt knob, the lock shaft 2 is turned, providing the conditions for subsequent linkage to achieve lock status display. Additionally, a rotating handle is provided at one end of the lock housing 1, allowing the user to easily open the lock by rotating the handle.

[0028] Figure 3 This is a schematic diagram from one perspective showing the cooperation of the sliding plate, display part, lock shaft, and toggle member in the status display structure of a lock according to this utility model. Figure 4This is a schematic diagram from another perspective showing the cooperation of the sliding plate, display section, lock shaft, and actuating component in the status display structure of a lock according to this utility model. Figures 1 to 4 As shown, a sliding cavity 11 is provided at the other end of the lock housing 1, providing space for the subsequent sliding of the display unit 31 and also providing guidance for the sliding of the display unit 31, maintaining the stability of the display unit 31 when switching displays. At the same time, a display window 12 is provided on the lock housing 1 and located in the sliding cavity 11, displaying part of the space inside the sliding cavity 11 through the display window 12, so that when the two display units 31 are in the sliding cavity 11, one of the two display units 31 can be selected to correspond to the display window 12, thereby realizing the display of the lock status, which makes it convenient for relevant personnel to obtain the lock status in a timely and intuitive manner. In addition, by setting the sliding cavity 11 at the end of the lock housing 1 away from the rotating handle, the display window 12 is kept away from the rotating handle, avoiding the rotating handle from obstructing the display, and the structural design is more reasonable.

[0029] Specifically, the sliding plate 3 is slidably disposed within the lock housing 1 in one direction. Preferably, the sliding direction of the sliding plate 3 is the length direction of the lock, i.e., the direction from the display window 12 to the rotating handle, satisfying the requirements of concealed installation within the lock housing 1 and adaptability to movement. Furthermore, one end of the sliding plate 3 extends to the display window 12, and the other end extends to the lock shaft 2, providing a condition for the sliding plate 3 to slide within the lock housing 1 by rotating the lock shaft 2, thereby allowing the sliding plate 3 to change the position of the two display sections 31 at the display window 12. At this time, the end of the sliding plate 3 extending to the display window 12 is provided with two display sections 31, allowing the two display sections 31 to move with the sliding plate 3, providing a condition for subsequent changes in the position of the display sections 31. In addition, arranging the two display sections 31 side-by-side along the sliding direction of the sliding plate 3 allows the two display sections 31 to move synchronously in the same direction, providing a condition for subsequently selecting one of the display sections 31 to cooperate with the display window 12 for display. During use, as the sliding plate 3 moves, one display unit 31 is located within the display window 12. That is, while the sliding plate 3 slides, one display unit 31 is positioned within the display window 12, while the other display unit 31 is located to the side of the display window 12 and covered by the lock case 1. This allows for the display of either the locked or unlocked state of the lock, facilitating timely and intuitive access to the current status of the lock by relevant personnel. Furthermore, the other end of the sliding plate 3 can engage with the lock shaft 2, enabling the sliding plate 3 to slide synchronously when the user operates the lock via the lock shaft 2. This achieves synchronized and automatic switching of the display status without requiring additional operation, making it more convenient and reducing usage limitations.

[0030] Specifically, the actuating element 4 is rotatably installed inside the lock housing 1. One end of the actuating element 4 is connected to the lock shaft 2, so that the lock shaft 2 can drive the actuating element 4 to rotate inside the lock housing 1. A lever 41 is provided on one side of the actuating element 4 along its radial direction, and a lever 42 is provided on the lever 41, so that when the lock shaft 2 drives the actuating element 4 to rotate, the lever 42 can be displaced under the action of the lever 41. Furthermore, a toggle hole 32 is provided on one end of the sliding plate 3 extending to the lock shaft 2. The toggle block 42 extends into the toggle hole 32, so that the toggle block 42 can drive the sliding plate 3 to slide within the lock housing 1, thereby adjusting the position of the two display sections 31 relative to the display window 12. That is, when the user turns the lock shaft 2 to adjust the state of the lock, the lock shaft 2 can drive the toggle member 4 to rotate, and drive the toggle block 42 to move through the lever 41. At the same time, the toggle block 42 drives the sliding plate 3 to move, so that the two display sections 31 on one end of the sliding plate 3 can switch positions relative to the display window 12, thereby achieving automatic adjustment of the display state without additional operation, making it more convenient to use and with a more reasonable structural design.

[0031] More specifically, each of the two display units 31 is provided with a locking indicator and an unlocking indicator 311. This allows the display window 12 to switch between displaying the locking and unlocking indicators when the sliding plate 3 moves and the two display units 31 align with the display window 12. This facilitates timely and intuitive access to the current status of the lock for relevant personnel, resulting in a more rational structural design. It is worth noting that the locking and unlocking indicators 311 are, but are not limited to, being installed on the display units 31 using adhesive methods, ensuring that the locking and unlocking indicators 311 are stably installed on their respective display units 31 and move with them.

[0032] More specifically, a cover plate 5 is embedded in the lock case 1 at the display window 12, covering the display window 12 to achieve external protection. Furthermore, the cover plate 5 is made of a transparent material, allowing personnel to observe the display section 31 inside the display window 12 through the cover plate 5, thus meeting usage requirements. Preferably, the cover plate 5 is made of materials including, but not limited to, acrylic, tempered glass, etc., and a suitable material can be selected according to usage requirements; specific material selection will not be elaborated here.

[0033] More specifically, the sliding plate 3 and the two display units 31 are an integrated structure, ensuring the structural strength between the sliding plate 3 and the display units 31. This allows the sliding plate 3 to stably drive the two display units 31 to move synchronously, achieving display state switching. Furthermore, the display units 31 are provided with several perforated holes 312. These holes reduce the weight of the display units 31, achieving a lightweight lock and reducing the burden on the door where the lock is installed. Simultaneously, this also reduces the manufacturing cost of the lock, minimizes material usage, and avoids resource waste.

[0034] More specifically, the sliding plate 3 is provided with a main clearance hole 33, which corresponds to the installation position of the lock cylinder on the lock, so that the installation of the sliding plate 3 will not affect the installation of the lock cylinder. Furthermore, the main clearance hole 33 is a strip-shaped hole arranged along the sliding direction of the sliding plate 3, so that the sliding plate 3 will not be interfered with by the lock cylinder when sliding, ensuring that the sliding plate 3 can move smoothly.

[0035] More specifically, reinforcing ribs 34 are provided on both sides of the sliding plate 3 and located on the main clearance hole 33. Each reinforcing rib 34 is arranged along the length direction of the main clearance hole 33. The reinforcing ribs 34 strengthen the structure of the part of the sliding plate 3 with the main clearance hole 33, and prevent the structural strength of the sliding plate 3 from being insufficient due to the opening of the main clearance hole 33, which could lead to breakage during use. The structural design is more reasonable.

[0036] More specifically, the actuation hole 32 is a "V" shaped hole, which means that when the actuating element 4 rotates, since the actuating block 42 is connected to the actuating element 4 by the lever 41, and the lever 41 is a structure that extends radially along the actuating element 4, the distance between the actuating block 42 and the central axis of the sliding plate 3 will change when the actuating element 4 rotates. At this time, setting the actuation hole 32 to a "V" shaped structure can not only meet the usage requirement of the actuating block 42 following the rotation of the actuating element 4, but also adapt to the linear sliding requirement of the sliding plate 3, avoiding the problem of jamming between the sliding plate 3 and the actuating block 42, and the structural design is more reasonable. Furthermore, the sliding plate 3 is also provided with a secondary clearance hole 35. The secondary clearance hole 35 is a strip-shaped hole and is arranged along the sliding direction of the sliding plate 3, so that the length of the secondary clearance hole 35 can cover the sliding stroke of the sliding plate 3. At this time, the actuating member 4 is placed in the secondary clearance hole 35, so that when the actuating member 4 rotates and drives the sliding plate 3 to slide, the secondary clearance hole 35 can adapt to the moving stroke of the sliding plate 3, ensuring that the sliding plate 3 can slide normally.

[0037] Figure 5 This is a schematic diagram of a cover plate according to a preferred embodiment of the present invention. Figure 1 , Figure 2 as well as Figure 5As shown, a recessed groove 121 is provided on the inner edge of the display window 12, forming a limiting step at the edge of the display window 12. Simultaneously, an extended outer edge 51 is provided on the outer side of the cover plate 5. When the cover plate 5 is installed in the display window 12, the outer edge 51 can be inserted into the groove 121 to limit the cover plate 5, preventing it from falling out of the display window 12 and out of the lock housing 1. Furthermore, a locking foot 52 is provided on the inner side of the cover plate 5 within the lock housing 1. A locking hole 13, which mates with the locking foot 52, is provided on the inner wall of the lock housing 1 beside the display window 12. When the cover plate 5 is installed in the display window 12, the locking foot 52 can be inserted into the locking hole 13 to further limit the cover plate 5, preventing it from moving relative to the lock housing 1. This results in a more stable and reliable structure after assembly.

[0038] More specifically, a protruding limiting part 14 is provided on the inner wall of the lock case 1. Simultaneously, a sliding groove 36 is provided at the connection between the sliding plate 3 and the display unit 31. The sliding groove 36 is arranged along the sliding direction of the sliding plate 3, ensuring that its arrangement adapts to the sliding direction of the sliding plate 3. Furthermore, the limiting part 14 extends into the sliding groove 36, allowing the sliding plate 3 to be guided by the cooperation of the limiting part 14 and the sliding groove 36 during sliding, thus improving the stability of the sliding plate 3. It also serves as a limiting structure to prevent excessive sliding of the sliding plate 3, ensuring that the sliding stroke of the sliding plate 3 remains within a preset stroke.

[0039] More specifically, along the sliding direction of the sliding plate 3, both sides of the sliding plate 3 are provided with actuation holes 32, and the two actuation holes 32 are symmetrically arranged about the central axis of the sliding plate 3. This makes it easier to assemble without having to consider the angle of the actuation component 4. The actuation block 42 can be selected to cooperate with one of the actuation holes 32.

[0040] The lock status display structure provided in this embodiment includes a lock housing 1, a lock shaft 2, a sliding plate 3, and a toggle member 4. A display window 12 is provided at one end of the lock housing 1, and a sliding plate 3, extending to the display window 12, is slidably disposed within the lock housing 1 in one direction. Two display sections 31 are provided at one end of the sliding plate 3 located at the display window 12, and a toggle hole 32 is provided at the other end of the sliding plate 3, extending to the lock shaft 2 of the lock. The lock shaft 2 is connected to a rotating toggle member 4, which includes a pen and a toggle block 42. The lever 42 extends into the lever hole 32, allowing the user to operate the lock shaft 2 and slide the sliding plate 3 to achieve the correspondence between one display section 31 and the display window 12. Furthermore, the other display section 31 can be aligned with the display window 12 by reversing the lock shaft 2. This enables the two display sections 31 to switch between display windows 12, and the display switching process is automatic following the movement of the lock shaft 2. This allows relevant personnel to obtain the current lock status in a timely and intuitive manner without the need for additional operation, thus improving ease of use.
