Abstract

A burglarproof door with anti-pry function includes a door leaf and a door frame. The door leaf includes an outer door panel and an inner door panel. The outer door panel has a snap-fit ​​protrusion near the lock. The door frame has a groove that matches the snap-fit ​​protrusion. The snap-fit ​​protrusion has a connecting hook hole at the lock position on the door leaf. The door frame has a rotating connecting hook driven by the lock tongue at the lock position. When the door is opened and the lock tongue retracts, the rotating connecting hook is in its natural state. When the door is closed and the lock tongue extends, the lock tongue drives the rotating connecting hook to rotate, and the connecting hook of the rotating connecting hook engages with the connecting hook hole of the snap-fit ​​protrusion. The door frame and the snap-fit ​​protrusion become a single unit, thereby improving the anti-pry performance of the burglarproof door. At the same time, the snap-fit ​​protrusion engaging with the groove on the door frame that matches the snap-fit ​​protrusion can prevent people from opening the lock by inserting soft cards or other means into the lock tongue position through the door gap.

Description

Technical Field

[0001] This invention belongs to the field of anti-pry doors, specifically relating to an anti-theft door with anti-pry function. Background Technology

[0002] Security doors serve as a barrier to interior building security, and their anti-theft and anti-pry performance directly impacts the safety of residents. Therefore, most security doors on the market incorporate anti-pry mechanisms on the door leaf and frame near the lock to enhance their anti-pry performance. For example, patent 202111633419.7, entitled "Anti-Pry Door," primarily uses a first anti-pry steel bar on the door leaf and a second anti-pry steel bar at a corresponding position on the door frame. However, both the first and second anti-pry steel bars are straight, flat structures with poor structural strength, making them susceptible to deformation from external forces. Furthermore, the first and second anti-pry steel bars function independently, failing to combine to enhance the door's resistance to damage. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a burglarproof door with anti-pry function.

[0004] To address the aforementioned technical problems, a burglarproof door with anti-pry function is provided, comprising a door leaf and a door frame. The door leaf includes an outer door panel and an inner door panel. The outer door panel has a snap-fit ​​protrusion near the lock, and the door frame has a groove that matches the snap-fit ​​protrusion. The snap-fit ​​protrusion has a connecting hook hole at the lock location on the door leaf. The door frame has a rotating connecting hook driven by the lock tongue at the lock location. The rotating connecting hook is rotatably mounted on the door frame via a pivot. One end of the rotating connecting hook is connected to the door frame via a return spring, and the other end has a connecting hook. When the door is opened and the lock tongue retracts, the rotating connecting hook is in its natural state. When the door is closed and the lock tongue extends, the lock tongue drives the rotating connecting hook to rotate, causing the connecting hook to engage with the connecting hook hole of the snap-fit ​​protrusion, thus forming a single unit between the door frame and the snap-fit ​​protrusion.

[0005] Furthermore, the fastening boss is T-shaped or L-shaped.

[0006] Furthermore, the door leaf is also equipped with a main lock and upper and lower auxiliary locks. The latching boss is provided with connecting hook holes at the positions where the main lock and upper and lower auxiliary locks are located on the door leaf, and the door frame is provided with rotating connecting hooks at the positions where the main lock and upper and lower auxiliary locks are located on the door leaf.

[0007] Furthermore, the door frame is provided with a detachable cover at the location where the rotating connecting hook is set, which facilitates the assembly of the rotating connecting hook.

[0008] The beneficial effects of this invention are as follows: when the door is opened and the lock tongue retracts, the rotating connecting hook is in its natural state. When the door is closed and the lock tongue extends, the lock tongue drives the rotating connecting hook to rotate, and the connecting hook of the rotating connecting hook engages with the connecting hook hole of the snap-fit ​​boss. The door frame and the snap-fit ​​boss form a single unit, thereby improving the anti-pry performance of the anti-theft door. At the same time, the snap-fit ​​boss also engages with the matching groove provided on the door frame, which can also prevent people from opening the door lock by inserting soft cards or other means into the lock tongue position through the door gap.

[0015] Certain terms are used in the specification and claims to refer to specific components. Those skilled in the art will understand that hardware manufacturers may use different names to refer to the same component. This specification and claims do not distinguish components based on differences in name, but rather on differences in function. The term "comprising" as used throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to." The following descriptions of preferred embodiments of the invention are intended to illustrate the general principles of the invention and are not intended to limit the scope of the invention. The scope of protection of this invention is determined by the appended claims.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings, but this is not intended to limit the scope of the invention.

[0017] Example

[0018] like Figure 1-7As shown, a burglarproof door with anti-pry function includes a door leaf 1 and a door frame 2. The door leaf 1 includes an outer door panel 1a and an inner door panel 1b. The outer door panel 1a has a latching boss 1a1 near the lock. The door frame 2 has a groove 2a that matches the latching boss 1a1. The latching boss 1a1 has a connecting hook hole 1a1-1 at the lock position on the door leaf 1. The door frame 2 has a rotating connecting hook 3 driven by the lock tongue at the lock position. The rotating connecting hook 3 is rotatably mounted on the door frame 2 via a rotating shaft 3b. The rotating connecting hook 3 extends to both sides along the rotating shaft 3b. One end of the rotating connecting hook 3 is connected to the door frame 2 via a return spring 3c, and the other end of the rotating connecting hook 3 is provided with a connecting hook 3a. Figure 6 As shown, when the door is opened and the lock tongue retracts, the rotating connecting hook 3 is in its natural state; Figure 8 As shown, when the door is closed, the lock tongue extends through the lock tongue hole 2b of the door frame 2, which drives the rotating connecting hook 3 to rotate. The connecting hook 3a of the rotating connecting hook 3 then passes through the connecting hole 2a1 at the position of the groove 2a and engages with the connecting hook hole 1a1-1 of the latching boss 1a1, thus forming a single unit between the door frame 2 and the latching boss 1a1. After the door frame 2 and the latching boss 1a1 are integrated, without using a key to retract the lock tongue, the connecting hook 3a of the rotating connecting hook 3 will always hook into the connecting hook hole 1a1-1 of the latching boss 1a1. At this time, it is impossible to pull the door leaf 1 outwards or open it from the outer door panel 1a side, thereby effectively improving the anti-pry performance of the security door. Simultaneously, when the door leaf 1 is closed, the latching boss 1a1 also engages with the groove 2a provided on the door frame 2, preventing unauthorized access to the lock tongue by inserting soft cards or other means.

[0019] More preferably, such as Figure 2 and Figure 3 As shown, the latching boss 1a1 is T-shaped or L-shaped. The latching boss 1a1 is set in a T-shape or L-shape to facilitate the setting of the connecting hook hole 1a1-1. At the same time, when it is set in a T-shape, there is also a small outward protrusion on its outer side, which improves the anti-pry performance and increases the difficulty for people to open the door lock by inserting soft cards or other means into the lock tongue.

[0020] More preferably, the door leaf 1 is also provided with a main lock 4 and upper and lower auxiliary locks 5. The latching boss 1a1 is provided with connecting hook holes 1a1-1 at the positions where the main lock 4 and the upper and lower auxiliary locks 5 are located on the door leaf 1. At the same time, the door frame 2 is provided with rotating connecting hooks 3 at the positions where the main lock 4 and the upper and lower auxiliary locks 5 are located on the door leaf 1. By providing rotating connecting hooks 3 at the positions of the main lock 4 and the upper and lower auxiliary locks 5, after the door leaf 1 is closed and the lock tongue is extended and locked, the door frame 2 and the latching boss 1a1 are more effectively connected at the positions of the main lock 4 and the upper and lower auxiliary locks 5, which more effectively improves the anti-pry performance of the security door.

[0021] More preferably, the door frame 2 is provided with a detachable cover 2c at the position where the rotating connecting hook 3 is located, so that the rotating connecting hook 3 can be easily assembled through the cover 2c.

[0022] The beneficial effects of this invention are as follows: when the door is opened and the lock tongue retracts, the rotating connecting hook is in its natural state. When the door is closed and the lock tongue extends, the lock tongue drives the rotating connecting hook to rotate, and the connecting hook of the rotating connecting hook engages with the connecting hook hole of the snap-fit ​​boss. The door frame and the snap-fit ​​boss form a single unit, thereby improving the anti-pry performance of the anti-theft door. At the same time, the snap-fit ​​boss also engages with the matching groove provided on the door frame, which can also prevent people from opening the door lock by inserting soft cards or other means into the lock tongue position through the door gap.

[0023] The foregoing description illustrates and describes preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
