Description

Technical Field

[0001] This utility model relates to the field of locks, and in particular to an anti-peeping key structure and an electronic lock. Background Technology

[0002] A peephole, also known as a peephole, is a small optical device installed on the door of a residential apartment. Its main purpose is to allow residents to observe the outside environment when the door is closed. With a peephole installed, people inside the apartment can clearly see outside, but those outside cannot easily see inside. Currently, peepholes have become a necessity for residential doors, serving a certain degree of security and burglary prevention.

[0003] However, installing a peephole requires a hole to be made in the door to accommodate it. This could allow criminals to damage the peephole, insert a special tool through the hole, press the door handle from the inside, and then enter the house, thus compromising the safety of people and property inside.

[0004] To address the issue of unlocking via the peephole, existing door locks incorporate a clutch assembly in the lock cylinder. The clutch assembly is triggered by changes in the position of the clutch disc, causing the lock cylinder to be in a free state, preventing the door from being opened via the inner handle. A toggle mechanism is used to change the clutch disc position, as seen in patent 202322472684.2. However, this toggle mechanism is complex, resulting in higher production and assembly costs. Furthermore, its lateral movement to change the clutch disc position is limited by lateral space, making it unsuitable for integration with electric mechanisms. Utility Model Content

[0005] The main purpose of this utility model is to provide an anti-peeping key structure to solve the problem of complex key structure.

[0006] This utility model proposes an anti-peeping key structure, wherein the clutch plate of the clutch assembly has a forward or backward protruding force-bearing protrusion at its end:

[0007] The anti-peeping key structure includes:

[0008] The key body includes a guide structure and an arc-shaped groove located at the upper end of the key body. The force-bearing protrusion is movably inserted into the arc-shaped groove, and the guide structure is slidably connected to the panel.

[0009] The positioning spring includes a spring coil and two spring arms, with opposing locking protrusions on the two spring arms, and the spring coil is connected to the key body;

[0010] The panel is equipped with positioning posts, and two spring arms are located on the left and right sides of the positioning posts respectively;

[0011] The key body can move up and down under external force to position the key body in the upper and lower positions;

[0012] The clutch assembly is engaged when the main body of the dial is in either the up or down position.

[0013] When the dial body is in either the up or down position, the clutch assembly is closed.

[0014] Furthermore, the guide structure includes a guide hole provided in the strip hole on the key body and a guide post provided on the panel, with the guide post being movably inserted into the guide hole.

[0015] Furthermore, there are two guide holes, which are arranged parallel to each other on the left and right sides of the key body.

[0016] Furthermore, the lower end of the key body is provided with a vertical plate, and the vertical plate is provided with an insertion hole through which two spring arms pass.

[0017] Furthermore, the key body is provided with a limiting hole, into which the positioning pin is inserted.

[0018] Furthermore, the positioning spring is connected to the key body via screws.

[0019] Furthermore, the toggle switch body is equipped with a force-bearing button that protrudes from the panel.

[0020] This utility model also proposes an electronic lock, including the aforementioned anti-peeping key structure.

[0021] Furthermore, the electronic lock also includes a key power mechanism, which is connected to the key body for transmission, and drives the key body to move up and down.

[0022] This utility model proposes an anti-peeping key structure and electronic lock.

[0026] Figure 4This is a schematic diagram of the structure of the anti-cat's eye key structure and the panel in the combined state of the present invention.

[0027] Figure 1-4 In the middle, there are key body 1, arc groove 11, guide structure 12, guide hole 121, guide post 122, upright plate 13, insertion hole 131, limit hole 14, positioning spring 2, spring ring 21, spring arm 22, locking protrusion 221, clutch assembly 3, clutch plate 31, force-bearing protrusion 311, panel 4, and positioning post 41. Detailed Implementation

[0028] The technical solution described in this paper will now be described in further detail with reference to the accompanying drawings.

[0029] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly. The connection can be a direct connection or an indirect connection.

[0030] Reference Figure 1-4 This utility model proposes an anti-peeping key structure. The clutch plate 31 of the clutch assembly 3 has a forward or backward protruding force-bearing protrusion 311 at its end. The anti-peeping key structure includes a key body 1 and a positioning spring 2. The key body 1 includes a guide structure 12 and an arc-shaped groove 11 located at the upper end of the key body 1. The force-bearing protrusion 311 is movably inserted into the arc-shaped groove 11, and the guide structure 12 is slidably connected to the panel 4. The positioning spring 2 includes a spring coil 21 and two spring arms 22. The two spring arms 22 have opposing locking protrusions 221, and the spring coil 21 is connected to the key body 1. The panel 4 has a positioning post 41, and the two spring arms 22 are located on the left and right sides of the positioning post 41, respectively. The key body 1 can move up and down under external force to make the key body 1 be in an upper position and a lower position. When the key body 1 is in one of the upper and lower positions, the clutch assembly 3 is open; when the key body 1 is in the other of the upper and lower positions, the clutch assembly 3 is closed.

[0031] This utility model proposes an anti-peeping key structure and electronic lock. Under the action of external force, the key body 1 changes between the upper and lower positions, thereby controlling the clutch component 3 to open or close, so as to control whether the lock cylinder enters the free state, thus solving the problem of unlocking through the peeping hole. Moreover, the anti-peeping key structure includes a key body 1 and a positioning spring 2, which is simple in structure and solves the problem of complex key structure.

[0032] In this embodiment, the positioning spring 2 is fixed by passing a screw through the spring coil 21 and fixing it to the key body 1. When the key body 1 is in the upper position, the force-bearing protrusion 311 is pressed upward by the arc groove 11, and the clutch plate 31 closes the clutch assembly 3. At this time, the rear handle can open and close the lock normally. When the key body 1 is in the lower position, the force-bearing protrusion 311 is released from the upward pressure of the arc groove 11, and the clutch assembly 3 is opened, realizing the rear handle in a free state. At this time, turning the rear door handle will not open the door. Therefore, even if the rear handle is turned with a special tool at the peephole, the door cannot be opened, which plays the role of preventing the peephole from unlocking. During the rotation of the handle, the force-bearing protrusion 311 slides along the arc groove 11.

[0033] It should be noted that, regarding the external force that causes the key body 1 to move up and down, in some embodiments, the key body 1 is moved manually by connecting the force point of the key body 1; in some embodiments, the key body 1 is moved by applying force to an electric power mechanism.

[0034] Furthermore, in some embodiments, the guide structure 12 includes a guide hole 121 provided in the strip hole on the key body 1 and a guide post 122 provided on the panel 4, the guide post 122 being movably inserted into the guide hole 121.

[0035] Specifically, the key body 1 is guided to move by sliding the guide post 122 along the guide hole 121. In some embodiments, the guide post 122 is a rectangular column, and the key body 1 is guided to move by the two parallel sides of the rectangular column. There can be one or more guide posts 122. When there are multiple guide posts 122, there are multiple corresponding guide holes 121 that are parallel to each other. In some embodiments, the guide post 122 is a cylinder, and there are multiple guide posts 122 and multiple corresponding guide holes 121 that are parallel to each other, thereby guiding the movement direction of the key body 1.

[0036] Furthermore, in some embodiments, two guide holes 121 are provided, and the two guide holes 121 are arranged parallel to each other on the left and right sides of the key body 1.

[0037] Specifically, the guide post 122 can slide along the guide hole 121 to guide the key body 1 to move up and down, making the key body 1 move stably, and the guide post 122 can also play a limiting role.

[0038] Furthermore, in some embodiments, the lower end of the key body 1 is provided with a vertical plate 13, and the vertical plate 13 is provided with an insertion hole 131, through which two spring arms 22 pass.

[0039] Specifically, because the side wall of the insertion hole 131 abuts against the end of the spring arm 22, the locking protrusion 221 of the spring arm 22 exerts a sufficiently large compressive force on the positioning post 41 to achieve the locking function.

[0040] Furthermore, in some embodiments, the key body 1 is provided with a limiting hole 14, and the positioning post 41 is inserted into the limiting hole 14.

[0041] Specifically, the positioning post 41 abuts against the edge of the limiting hole 14 to achieve the limiting effect.

[0042] Furthermore, in some embodiments, the positioning spring 2 is connected to the key body 1 by a screw.

[0043] Specifically, the key body 1 has a connecting post for the screw. After the screw passes through the spring ring 21, it is screwed onto the connecting post so that the positioning spring 2 is connected to the key body 1 by the screw.

[0044] Furthermore, in some embodiments, the key body 1 is provided with a force-receiving button that protrudes from the panel 4.

[0045] Specifically, the force button can be either an integral part of the key body 1 or connected to the key body 1; the panel 4 is provided with a strip-shaped hole for the force button to move up and down. By manually moving the force button, the key body 1 can overcome the limitations of the positioning spring 2 and the positioning post 41, so that the key body can reach the upper or lower position.

[0046] This utility model also proposes an electronic lock, including the aforementioned anti-peeping key structure.

[0047] Specifically, the electronic lock has the aforementioned anti-peeping key structure, and the electronic lock can be an electric lock such as a smart lock.

[0048] Furthermore, in some embodiments, the electronic lock also includes a key-operated power mechanism, which is connected to the key-operated body 1 and drives the key-operated body 1 to move up and down.

[0049] Specifically, an electric toggle mechanism can replace manual operation to move the toggle body 1 up and down. In some embodiments, based on the detection status, when a person leaves, the toggle mechanism can be automatically controlled to move the toggle body 1 up / down to open the clutch assembly 3, thus achieving a free-running state for the rear handle. When a person is detected opening the door at the rear handle, the toggle mechanism can be automatically controlled to move the toggle body 1 up / down to close the clutch assembly 3, thus achieving a free-running state for the rear handle.

[0050] This utility model proposes an anti-peeping key structure and electronic lock. Under the action of external force, the key body 1 changes between the upper and lower positions, thereby controlling the clutch component 3 to open or close, so as to control whether the lock cylinder enters the free state, thus solving the problem of unlocking through the peeping hole. Moreover, the anti-peeping key structure includes a key body 1 and a positioning spring 2, which is simple in structure and solves the problem of complex key structure.

[0051] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
