Description

Technical Field

[0001] This utility model relates to the field of security door technology, and in particular to a security door with all-around locking. Background Technology

[0002] Security doors are physical barriers specifically designed to enhance home security. They greatly increase the difficulty and time it takes for criminals to enter. A qualified security door can effectively resist violent damage such as prying, smashing, and sawing, giving homeowners more time to call the police, neighbors to notice, or for the police to arrive.

[0003] Security doors are designed to be extremely difficult to pick or forcibly break into due to their sturdy structure and complex locks. Most ordinary criminals prefer to use force or destructive methods rather than technical methods. Forced entry or destructive methods require almost no special training and the tools are readily available, while technical methods require extensive professional practice and an understanding of the internal structure of various locks.

[0004] The article, published under the publication number CN217176360U and titled "All-around Locking Security Door," mentions that by installing a door lock mechanism inside the security door, the door lock mechanism can effectively protect the security door.

[0005] However, improving the security of a security door solely through the door lock mechanism has limited effectiveness. Criminals can easily open the security door by damaging the lock. Therefore, a more secure security door is proposed. Utility Model Content

[0006] In view of the problems mentioned above, the technical problem to be solved by this utility model is to provide an all-around locking anti-theft door.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an all-around locking anti-theft door, including a door frame, a door leaf and a hinge for hinged to the door frame and the door leaf, a door lock is installed on the outer end face of the door leaf near one side, and a latch controlled by the door lock is provided on one side of the door leaf, which extends into the door frame when locked. A position sensor is installed on the outside of the latch, and a controller is installed inside the door lock to monitor the position changes of the position sensor; The door leaf is equipped with a locking mechanism, which includes a servo motor electrically connected to the controller inside the door lock and a locking block that is controlled by the servo motor to extend inward and outward. When the locking block extends outward, it locks with the door frame. When the position sensor moves outward, the locking block also extends outward. Conversely, when the position sensor moves inward, the locking block retracts inward.

[0008] A further preferred embodiment of this utility model is that the door lock has a battery inside to provide a driving force for the lock tongue and servo motor.

[0009] A further preferred embodiment of this utility model is: an installation cavity is provided on the inward side of the door leaf, the locking mechanism is installed in the installation cavity, and a protective cover is provided on the outside of the installation cavity to cover the locking mechanism.

[0010] A further preferred embodiment of this utility model is: the four sides of the protective cover are all embedded in the mounting cavity and fit against the inner wall of the mounting cavity; the sides of the protective cover are fixed to the door leaf by bolts; when the door leaf is closed, the bolts are located inside the door frame to hide the bolts.

[0011] A further preferred embodiment of this utility model is: the locking mechanism further includes a slide rail installed on the inner wall of the mounting cavity, the locking block is slidably disposed on the slide rail, and the side of the protective cover is provided with an opening for the movement of the locking block; The servo motor is fixed in the mounting cavity, and its output end has a threaded shaft. A threaded sleeve is threadedly connected to the threaded shaft. A connecting plate is provided between the threaded sleeve and the locking block. The two ends of the connecting plate are respectively hinged to the threaded sleeve and the locking block. When the threaded shaft rotates in both directions, the degree of inclination of the connecting plate changes, causing the locking block to slide in and out.

[0012] A further preferred embodiment of this utility model is: the slide rail has a T-shaped cross-section, and the locking block on the inward side cooperates with the T-shaped slide rail.

[0013] A further preferred embodiment of this utility model is: the door frame has an integral inner protrusion layer on the inner side, and the outer side of the inner protrusion layer is used to abut against the door leaf when the door is closed.

[0014] A further preferred embodiment of this utility model is: when the locking block extends outward, the portion extending outward from the protective cover abuts against the inward side of the inner protruding layer; when the locking block retracts inward, it separates from the inner protruding layer.

[0015] A further preferred embodiment of this utility model is that both the inner protruding layer and the locking block are made of alloy material.

[0016] A further preferred embodiment of this utility model is: there is a gap between the outer side of the protective cover and the inner protruding layer to prevent the protective cover from getting stuck with the inner protruding layer when the door is opened or closed.

[0017] Compared with the prior art, the advantages of this utility model are: 1. In traditional lock tongue locking, the locking mechanism also locks. Even if criminals successfully damage the door lock and lock tongue, the lock block driven by the servo motor can still firmly lock the door leaf to the door frame, greatly increasing the difficulty and time of illegal opening. The position sensor on the lock tongue and the servo motor of the locking mechanism are intelligently linked through the controller. When the lock tongue is locked, the locking mechanism is automatically driven to lock, improving convenience. At the same time, if the door lock and lock tongue are damaged, it will cause a power outage, keeping the locking mechanism in position and increasing the difficulty of opening.

[0018] 2. Traditional locks have small and concentrated locking points, making them easy to be targeted and damaged. This application forms a locking surface on the side of the door leaf, making it difficult for criminals to disable the entire locking system through small-scale damage. Even if the lock block is partially damaged, the remaining parts can still play an effective locking role.

[0019] 3. The locking mechanism is located inside the door panel's mounting cavity, making it impossible to directly observe key structures and weak points from either the inside or outside, thus preventing damage to critical locations. Attached Figure Description

[0023] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0025] This embodiment mainly describes a 360° locking security door. Please refer to [link / reference]. Figures 1-7 Specifically, the following applies: Currently, most household security doors rely solely on lock mechanisms to enhance security, which has limited effectiveness. Criminals can easily disable the door by damaging the lock mechanism. Since lock mechanisms are limited in size, only small-scale damage is necessary. Therefore, a fully locking security door is proposed, comprising a door frame 1, a door leaf 2, and a hinge 3 for connecting the door frame 1 and the door leaf 2. A lock 4 is installed on the outer end face of the door leaf 2 near one side. One side of the door leaf 2 has a latch 41 that extends and retracts under the control of the lock 4. When locked, the latch 41 extends into the door frame 1. A position sensor 42 is installed on the outside of the latch 41, and a controller is installed inside the door lock 4 to monitor the position changes of the position sensor 42; The door leaf 2 is equipped with a locking mechanism 5. The locking mechanism 5 includes a servo motor 56 electrically connected to the controller inside the door lock 4 and a locking block 52 that controls the inward and outward extension movement through the servo motor 56. When the locking block 52 extends outward, it locks with the door frame 1. When the position sensor 42 moves outward, the locking block 52 also extends outward. Conversely, when the position sensor 42 moves inward, the locking block 52 retracts inward.

[0026] Specifically, the door frame 1, door leaf 2, and hinge 3 are all existing technologies. Controlling the opening and closing of the door leaf 2 through the door lock 4 and the latch 41 is also a common existing technology. Through the locking mechanism 5 located inside the door leaf 2, under the action of the controller inside the door lock 4 and the position sensor 42 of the latch 41, the locking mechanism 5 and the latch 41 are linked, thereby controlling the door leaf 2 to be locked by the latch 41 and the locking mechanism 5. When the lock block 52 cooperates with the door frame 1 to lock, the locking range is relatively large and it is not easy to be damaged.

[0027] The door lock 4 has a battery inside, which provides a driving force for the bolt 41 and the servo motor 56.

[0028] Specifically, door lock 4 is an existing smart lock, which originally contains a battery for power supply. The battery can also drive the servo motor 56. It should be noted that the controller in door lock 4 is also powered by the battery. The controller and position sensor 42 are both existing structures.

[0029] like Figure 5 As shown, the door leaf 2 has an inward-facing mounting cavity 21, the locking mechanism 5 is installed in the mounting cavity 21, and the outer side of the mounting cavity 21 is provided with a protective cover 22 to cover the locking mechanism 5.

[0030] Specifically, the locking mechanism 5 is installed in the mounting cavity 21 of the door leaf 2. This increases the utilization of space in the door leaf 2, and while maintaining a certain strength, reduces its thickness after the locking mechanism 5 is installed, making the door leaf 2 lighter. Then, the protective cover 22 covers the locking mechanism 5, preventing the locking mechanism 5 from being exposed and preventing its structure and the location of the servo motor 56 from being observed. In the event of forced entry, it is not easy to find the key position.

[0031] like Figure 5 As shown, the protective cover 22 is embedded in the mounting cavity 21 on all four sides and fits against the inner wall of the mounting cavity 21. The protective cover 22 is fixed to the door leaf 2 by bolts. When the door leaf 2 is closed, the bolts are located inside the door frame 1 to hide the bolts.

[0032] Specifically, the protective cover 22 is embedded in the mounting cavity 21 and fixed by bolts. The bolts are located on the side of the protective cover 22. It should be noted that during installation, the bolts pass through the narrow side of the door leaf 2 and inward to fix the protective cover 22. Therefore, when the door frame 1 and the door leaf 2 are closed, the bolts are located inside the door frame 1, making the bolts hidden and difficult to damage in case of damage.

[0033] like Figures 5-6 As shown, the locking mechanism 5 also includes a slide rail 51 installed on the inner wall of the mounting cavity 21, the locking block 52 is slidably mounted on the slide rail 51, and the side of the protective cover 22 is provided with a cavity 23 for the movement of the locking block 52. The servo motor 56 is fixed inside the mounting cavity 21. Its output end has a threaded shaft 55. The threaded shaft 55 is fitted with a threaded sleeve 54 that is threadedly connected to it. A connecting plate 53 is provided between the threaded sleeve 54 and the locking block 52. The two ends of the connecting plate 53 are respectively hinged to the threaded sleeve 54 and the locking block 52. When the threaded shaft 55 rotates in both directions, the degree of inclination of the connecting plate 53 changes, causing the locking block 52 to slide inward and outward.

[0034] Specifically, the slide rail 51 is fixed to the door leaf 2 and is controlled by the servo motor 56 to rotate the threaded shaft 55. It can rotate forward or backward, so the position of the threaded sleeve 54 on the threaded shaft 55 can be moved, changing the inclination of the connecting plate 53, so that the locking block 52 can slide in the inward and outward directions. Based on this, the position sensor 42 detects the position change and realizes the controller to control the servo motor 56 to rotate forward and backward.

[0035] like Figure 5 As shown, the slide rail 51 has a T-shaped cross-section. The locking block 52 on the inward side cooperates with the T-shaped slide rail 51. The locking block 52 has a T-shaped opening that cooperates with the slide rail 51. After the connecting plate 53 is removed, the locking block 52 can be removed laterally, and the locking block 52 can be separated from the slide rail 51, which is convenient for thickness maintenance.

[0036] like Figure 4 and Figure 7 As shown, the door frame 1 has an inner protruding layer 11 on the inner side, and the outer side of the inner protruding layer 11 is used to abut against the door leaf 2 when the door is closed.

[0037] Specifically, the inner protruding layer 11 is used to abut against the door leaf 2, so that the door leaf 2 increases the sealing effect after closing, and at the same time increases the curvature of the door gap, avoiding the need to use tools to extend into the door.

[0038] like Figure 4 and Figure 7 As shown, when the locking block 52 extends outward, the portion extending out of the protective cover 22 abuts against the inward side of the inner protruding layer 11, and when the locking block 52 retracts inward, it separates from the inner protruding layer 11.

[0039] Specifically, the inner protruding layer 11 is held by the door leaf 2 and the lock block 52. Even if the lock tongue 41 or the hinge 3 is damaged, the door leaf 2 can remain in the same position, thus improving the anti-theft effect. It should be noted that since the inner protruding layer 11 is integrated with the door frame 1 and has a relatively long extension length, even if there is local damage, it will not have an impact.

[0040] The inner protruding layer 11 and the locking block 52 are both made of alloy material, which increases their sturdiness.

[0041] There is a gap between the outer side of the protective cover 22 and the inner protruding layer 11 to prevent the protective cover 22 from getting stuck with the inner protruding layer 11 when the door leaf 2 is opened and closed. With the protective cover 22, the door leaf 2 can also be opened and closed normally.

[0042] Working principle: The hinge 3 controls the opening and closing of the door leaf 2. When the door leaf 2 is closed, it works with the door frame 1 to lock it. However, if the door lock 4 is damaged, its bolt 41 is also easily damaged, so the door leaf 2 can be opened directly. Therefore, the door lock 4 controls the bolt 41 to cooperate with the door frame 1 to achieve locking. During the movement of the bolt 41, the position sensor 42 also changes position, so that the controller inside the door lock 4 receives the signal from the position sensor 42 and transmits the signal to the servo motor 56 to control the forward rotation of the servo motor 56. Figures 5-6 As shown, when the connecting plate 53 is in a horizontal state, the locking block 52 is pushed outward to cooperate with the door frame 1, locking the door leaf 2 in multiple directions. When the door lock 4 is damaged and power is cut off, the position of the locking block 52 remains unchanged and the locked state is maintained. Therefore, even if the door lock 4 is damaged, it is not easy to open the door leaf 2. When the lock tongue 41 retracts inward, the locking block 52 can also retract inward, and the door leaf 2 can be opened.

[0043] Secondly, the inner protruding layer 11 is designed so that one side of the inner protruding layer 11 abuts against the door leaf 2 and the other side abuts against the lock block 52, so that the inner protruding layer 11 is clamped. Even if the lock tongue 41 and the hinge 3 are damaged, the door leaf 2 can still be locked to the door frame 1 and is not easily damaged.

[0044] When criminals want to damage the locking mechanism 5, they need to chisel through the door leaf 2 from the outside or destroy the protective cover 22 from the inside, both of which are inconvenient. When the door leaf 2 is closed, the protective cover 22 is fixed on the side, so there are no exposed bolts. Therefore, the security door in the closed state is not easy to be damaged from the inside or the outside.

[0045] In addition, the inner protruding layer 11, the door leaf 2 and the locking block 52 make the door gap extend in a tortuous manner, so that even if criminals want to damage it along the door gap, it will be difficult. Moreover, the locking block 52 has a certain length, so damaging a part of the locking block 52 can also achieve the locking effect in the rest of the position.

[0047] The above provides a detailed description of the all-around locking anti-theft door provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The above description of the embodiments is only for the purpose of helping to understand this utility model and its core ideas.
