Description

Technical Field

[0001] This utility model relates to the field of security door technology, and more specifically, it relates to a double-lock security door with an anti-pry structure. Background Technology

[0002] In recent years, with the increasing complexity of public security, theft has become more diversified and sophisticated. As the first line of defense for important locations such as homes and offices, security doors have received widespread attention for their anti-theft performance. However, commonly available security doors still pose certain security risks when faced with professional burglary tools and techniques, especially in terms of pry resistance.

[0003] Currently, a common method of prying open doors involves using a card with a certain degree of elasticity and hardness. This card is inserted into the gap between the door panel and the door frame, and by pushing the lock tongue back into the door lock, the door can be easily opened. This method utilizes the gap between the door panel and the door frame, as well as the structural features of the lock tongue. Once the lock tongue is pushed back by the card, the locking state of the door is disrupted, and the door can be easily opened.

[0004] The gap between the door leaf and the door frame when the security door is closed is often the weak point of the security door, and thieves can easily use this gap to pry open the door.

[0005] In conclusion, existing security doors have many shortcomings in terms of anti-pry structure, and a brand-new security door with anti-pry structure is needed to overcome the above problems, so as to improve the anti-pry performance of security doors and protect people's lives and property. Utility Model Content

[0006] In view of the problems existing in the prior art, this utility model provides a double-lock security door with an anti-pry structure to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a double-lock anti-theft door with an anti-pry structure, comprising a first door frame and a first door panel, wherein a first door lock is installed on the first door panel for connecting the first door panel and the first door frame, a first baffle is fixed on the first door panel for covering the gap between the first door panel and the first door frame, and a first slot is provided between the first door panel and the first baffle.

[0008] By adopting the above technical solution, when the prying card is inserted horizontally from the gap between the first baffle and the first door frame, it will extend into the first slot and will not undergo elastic deformation to enter the gap between the first door panel and the first door frame.

[0009] The present invention is further configured as follows: the double-lock anti-theft door with an anti-pry structure also includes a second door frame fixed to the first baffle, a second door panel hinged to one side of the second door frame, and the first door lock placed inside the second door frame.

[0010] A second door lock is installed on the second door panel to connect the second door panel and the second door frame.

[0011] The second door frame and the second door panel are used to shield and protect the first door lock.

[0012] The present invention is further provided that a second baffle is fixed on the second door panel to cover the gap between the second door panel and the second door frame. The second baffle can prevent the prying card from being directly inserted between the second door panel and the second door frame.

[0013] The present invention is further configured such that a second slot is provided between the second door panel and the second baffle. When the prying card is inserted laterally through the gap between the second baffle and the second door frame, it will directly extend into the second slot without undergoing elastic deformation and entering the gap between the second door panel and the second door frame, thus preventing the second door lock from being pried open.

[0014] This invention is further configured such that a camera is installed inside the second door frame. When the second door lock is opened, the camera can record the image of a person, serving as a warning and protective measure.

[0015] The present invention is further provided that the first door frame is provided with a first clearance groove for the bolt of the first door lock to extend into.

[0016] The present invention is further provided that the second door frame is provided with a second clearance groove for the bolt of the second door lock to extend into.

[0017] Compared with the prior art, this utility model provides a double-lock security door with an anti-pry structure, which has the following beneficial effects:

[0018] 1. This security door adopts a double-lock structure. The second lock provides initial protection for the first lock, and the first lock then locks the first door panel and the first door frame, increasing the difficulty of prying the door and thus playing a certain role in preventing theft.

[0019] 2. The security door has a first slot between the first door panel and the first baffle. When a thief uses a card to pry open the door, the card will be inserted into the first slot and will not be able to enter the gap between the first door panel and the first door frame, thus preventing the thief from prying open the door.

[0020] 3. The security door has a second slot between the second door panel and the second baffle to prevent the second door lock from being pried, adding an extra layer of protection. Attached Figure Description

[0028] Please see Figure 1-3 A double-lock security door with an anti-pry structure includes a first door frame 1 and a first door panel 2. A first door lock 3 is installed on the first door panel 2 to connect the first door panel 2 and the first door frame 1. A first baffle 4 is fixed on the first door panel 2 to cover the gap between the first door panel 2 and the first door frame 1. A first slot 5 is provided between the first door panel 2 and the first baffle 4. A first clearance groove 101 is provided on the first door frame 1 for the lock tongue of the first door lock 3 to extend into.

[0029] In practical applications, the first baffle 4 is fixedly installed on the first door panel 2. When the first door panel 2 is closed, the first baffle 4 blocks the gap between the first door panel 2 and the first door frame 1. If a prying tool is inserted from the side of the first baffle 4 into the gap between the first baffle 4 and the first door frame 1, the prying tool will be inserted directly into the first slot 5 without bending into the gap between the first door panel 2 and the first door frame 1. Therefore, it can prevent the prying tool from pushing the bolt of the first door lock 3 back into the first door lock 3, thus preventing the locking state between the first door panel 2 and the first door frame 1 from being destroyed.

[0030] The double-lock security door with anti-pry structure also includes a second door frame 6 fixed to the first baffle 4. A second door panel 7 is hinged to one side of the second door frame 6. The first door lock 3 is placed inside the second door frame 6. A second door lock 8 for connecting the second door panel 7 and the second door frame 6 is installed on the second door panel 7. The second door frame 6 and the second door panel 7 are used to shield and protect the first door lock 3. A second clearance groove 601 is provided on the second door frame 6 for the bolt of the second door lock 8 to extend into.

[0031] In practical applications, the second door frame 6 is fixed on the second baffle 9, and the first door lock 3 is placed in the area of ​​the second door frame 6. The first door lock 3 is shielded by the second door panel 7 and the second door frame 6, which plays a certain protective role.

[0032] In this embodiment, a second baffle 9 is fixed on the second door panel 7 to cover the gap between the second door panel 7 and the second door frame 6. The second baffle 9 can prevent prying tools from being directly inserted between the second door panel 7 and the second door frame 6. A second slot 10 is provided between the second door panel 7 and the second baffle 9. When a prying tool is inserted laterally from the gap between the second baffle 9 and the second door frame 6, it will directly extend into the second slot 10 without undergoing elastic deformation and entering the gap between the second door panel 7 and the second door frame 6, thus preventing the second door lock 8 from being pried open.

[0033] In practical applications, a second baffle 9 is fixed on the second door panel 7. When the second door panel 7 is closed, the second baffle 9 blocks the gap between the second door panel 7 and the second door frame 6. If a prying tool is inserted from the side of the second baffle 9 into the gap between the second baffle 9 and the second door frame 6, the prying tool will be inserted directly into the second slot 10 without bending into the gap between the second door panel 7 and the second door frame 6. Therefore, it can prevent the prying tool from pushing the bolt of the second door lock 8 back into the second door lock 8, thus preventing the locking state between the second door panel 7 and the second door frame 6 from being destroyed.

[0034] The present invention is further configured such that a camera 11 is installed inside the second door frame 6. When the second door lock 8 is opened, the camera 11 can record the image of a person, which serves as a warning and protection function.

[0035] In practical applications, the data captured by camera 11 can be transmitted to the cloud. When a thief opens the second door panel 7 and thus unlocks the first door lock 3, camera 11 can record the thief's image and transmit it to the cloud, serving as a warning to the thief.
