AI Technical Summary
Existing security doors have large gaps, making them easy for thieves to pry open by inserting soft cards or other objects into the lock tongue, thus making theft unavoidable.
An anti-theft door structure with a shielding plate and a blocking plate was designed. The shielding plate slides along a slide rail to block the door gap and locks in conjunction with the first door lock. The blocking plate moves synchronously with the lock tongue to close both sides of the lock tongue. The double-layer blocking structure prevents objects from being inserted to pry the lock.
It effectively prevents thieves from prying open the lock by inserting the bolt through the door gap, thus improving the security of the security door and enhancing its ability to prevent theft.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of security door technology, specifically a high-security security steel door. Background Technology
[0002] Security steel doors are made of high-quality steel for the door frame, door panel, and skeleton, and filled with materials such as honeycomb paper, polyurethane, and aviation aluminum foil. They are also equipped with security locks and handles. Steel itself is not easily combustible, so security steel doors can effectively prevent the spread of fire in the event of a fire, providing valuable time for escape and rescue. At the same time, they can also insulate against smoke and high temperatures, providing greater protection for people's safety.
[0003] One existing method of theft involves inserting a soft card or similar object into the door gap to pry open the bolt and unlock the door. This theft is mainly due to the large gaps in the door, but all existing security doors have gaps, making this method of prying unavoidable. Therefore, we propose a high-security steel door to solve the problems mentioned above. Utility Model Content
[0004] The purpose of this utility model is to provide a high-security anti-theft steel door to solve the problem mentioned in the background art that the theft is mainly due to the large gap in the door, but existing anti-theft doors all have gaps, which makes it impossible to avoid this kind of prying.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-security anti-theft steel door, comprising a door frame and a door panel, wherein the door panel is installed inside the door frame;
[0006] Also includes:
[0007] A handle is provided on both sides of the door panel surface. A second door lock is provided on the inner edge of the door panel and is located below the handle. The second door lock includes a latch and is located in the middle of the outer edge of the door panel. A lock groove is provided inside the door panel and the latch is located inside the lock groove. A shielding plate is provided on the surface of the door panel and is located at the front end of the second door lock.
[0008] A sliding groove is provided on both sides of the lock groove and is connected to the inside of the lock groove. A baffle plate is symmetrically provided on both sides of the outer side of the lock tongue and the baffle plate is slidably engaged inside the sliding groove. A lock hole is provided in the middle of the inner side of the door frame and the lock tongue is slidably engaged inside the lock hole. A locking groove is symmetrically provided on both sides of the lock hole and the baffle plate is movably engaged inside the locking groove. The baffle plate and the lock tongue are connected by a connecting block.
[0009] Preferably, the outer side of the door panel is provided with a slide rail, and two sets of slide rails are provided and located on the upper and lower sides of the second door lock respectively, and the shielding plate slides at the front end of the door panel through the connection with the slide rail.
[0010] Preferably, a first door lock is provided on the outer side of the door frame, and the first door lock is locked to the shielding plate. A hole is provided on one side of the surface of the shielding plate, and the hole is aligned with the first door lock and the second door lock respectively.
[0011] Preferably, a blocking plate is provided on the outer side of the shielding plate, and the blocking plate is aligned with the second door lock.
[0012] Preferably, a slot is provided on one side of the surface of the shielding plate, and the slot is engaged with the handle.
[0013] Preferably, the first door lock and the second door lock share the same key.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] (1) By setting up a shielding plate, after closing the door, the shielding plate is moved horizontally so that the hole on the shielding plate is aligned with the first door lock. At this time, the shielding plate will block the door gap. The first door lock is locked with a key so that the positioning pin extends and engages in the pin groove on the inner side of the shielding plate, thereby limiting the movement of the shielding plate. The shielding plate can only be slid by inserting the key through the hole into the first door lock. A blocking plate is set on the back of the shielding plate to block the second door lock and prevent thieves from damaging the second door lock, thereby improving security.
[0016] (2) The cover plate and the lock tongue move synchronously, so that the cover plate and the lock tongue can extend synchronously and engage with the locking groove to seal both sides of the lock tongue, preventing thieves from inserting objects such as soft cards into the door gap to pry open the lock tongue. The double-layer shielding structure of the cover plate and the shielding plate can effectively prevent external objects from being inserted into the door gap to pry open the lock tongue.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] This utility model provides a high-security anti-theft steel door, which includes a door frame 1 and a door panel 2, with the door panel 2 installed inside the door frame 1. The main problem addressed by this utility model is that theft is primarily caused by large gaps in the door, but existing anti-theft doors all have gaps, making it unavoidable to prevent this type of prying.
[0024] For the device provided by this utility model, please refer to Figure 1-4 The following is a detailed introduction.
[0025] Handles 10 are provided on both sides of the surface of the door panel 2. A second door lock 14 is provided on the inner edge of the door panel 2, and the second door lock 14 is located below the handles 10. The second door lock 14 includes a latch 3, which is located in the middle of the outer edge of the door panel 2. A lock groove 9 is provided inside the door panel 2, and the latch 3 is located inside the lock groove 9. A shielding plate 11 is provided on the surface of the door panel 2, and the shielding plate 11 is located at the front end of the second door lock 14. A slide rail 12 is provided on the outer side of the door panel 2. The slide rail 12 has two sets and is located at the first... The upper and lower sides of the second door lock 14 are connected to the shielding plate 11, which moves at the front end of the door panel 2 via the connection with the slide rail 12. The slide rail 12 allows the shielding plate 11 to slide left and right at the front end of the door panel 2, thereby moving the shielding plate 11 to cover the door gap and prevent thieves from damaging the lock tongue through the door gap. A first door lock 13 is provided on the outer side of the door frame 1, and the first door lock 13 is locked to the shielding plate 11.
