Description

Technical Field

[0001] This utility model relates to the field of observation window technology for security doors, and more specifically, to a quick-detachable observation window assembly for security doors. Background Technology

[0002] A quick-disassembly security door observation window component is a new type of security component developed to address the core contradiction of traditional security door observation windows: "easy to disassemble if pry-proof, easy to disassemble if unsecured." It combines diverse user needs with industry standard upgrades. Its core advantages lie in balancing quick disassembly convenience, high-strength anti-theft performance, and adaptability to all scenarios, while incorporating lightweight and environmentally friendly materials and intelligent compatibility design.

[0003] Traditional observation window assemblies use a fixed structure secured with screws and sealed with adhesive. This type of observation window has drawbacks in terms of disassembly and movement. Firstly, the screw-fastening and adhesive sealing makes the observation window difficult to disassemble. Since screws are easily exposed to air for a long time, they are prone to rusting. Rusty screws are easily damaged during disassembly, making them impossible to remove and potentially damaging the observation window itself, thus increasing the difficulty of disassembly. Therefore, a quick-disassembly observation window assembly for security doors is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a quick-detachable observation window assembly for security doors to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a quick-detachable observation window assembly for a security door, including a door frame body. Two hinges are fixedly installed on the outer side of the door frame body, and the two hinges are symmetrically arranged. The same door panel body is fixedly installed on the two hinges. The door panel body rotates on the door frame body through the two hinges. A rectangular slot is opened on one side of the door panel body, and an observation window assembly is disposed in the rectangular slot. The observation window assembly is used for observing the outside of the door.

[0006] As a further improvement to this technical solution, the observation window assembly includes a rectangular frame, and a rectangular glass window is fixedly installed inside the rectangular frame. The rectangular glass window is used for observation outside the door.

[0007] As a further improvement to this technical solution, a rotating shaft is fixed on both sides of the rectangular glass window near the bottom, and the two rotating shafts are arranged symmetrically. A U-shaped limiting block is provided on the outer side of each rotating shaft, and the two U-shaped limiting blocks are respectively fixedly connected to the inner walls on both sides of the rectangular slot.

[0008] As a further improvement to this technical solution, sliding plates are fixedly connected to the inner walls on both sides of the rectangular slot. The two sliding plates are close to the inner wall of the top side of the rectangular slot. Sliding grooves are opened on the opposite side of the two sliding plates, and the two sliding grooves are symmetrically arranged. An L-shaped receiving plate is fixedly connected between the two sliding plates. Two circular holes are opened on the top side of the L-shaped receiving plate, and the two circular holes are symmetrically arranged.

[0009] As a further improvement to this technical solution, each of the circular holes is slidably connected with a sliding pin, and one end of each of the two sliding pins is fixedly connected to the same L-shaped clamping plate. Each sliding pin is fitted with a compression spring on its outer side, the top end of the compression spring is fixedly connected to the inner side of the L-shaped receiving plate, and the bottom end of the sliding pin is fixedly connected to the top side of the L-shaped clamping plate.

[0010] As a further improvement to this technical solution, both of the L-shaped clamping plates are fixedly connected to sliding limit blocks, and the two sliding limit blocks are symmetrically arranged, with the two sliding limit blocks slidably connected in the two sliding grooves respectively.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In quick-detachable security door observation window assemblies, traditional observation window assemblies, which use a fixed structure secured with screws and sealed with adhesive, present difficulties in disassembly. The newly designed observation window assembly facilitates the disassembly of the rectangular frame and rectangular glass window. First, the L-shaped clamping plate is pushed vertically upwards. Simultaneously, two sliding limit blocks and two sliding grooves guide the L-shaped clamping plate, and the L-shaped clamping plate compresses two compression springs. Then, the rectangular frame and rectangular glass window are removed from the rectangular groove, allowing workers to easily replace or clean them, thus solving the problem of difficult disassembly of the rectangular frame and rectangular glass window.

[0016] Please see Figures 1-4 As shown, this embodiment provides a quick-detachable observation window assembly for a security door, including a door frame body 100. Two hinges 200 are fixedly installed on the outside of the door frame body 100, and the two hinges 200 are symmetrically arranged. The same door panel body 300 is fixedly installed on the two hinges 200. The door panel body 300 rotates on the door frame body 100 through the two hinges 200. A rectangular slot 400 is opened on one side of the door panel body 300. An observation window assembly 500 is provided in the rectangular slot 400. The observation window assembly 500 is used to observe outside the door. The observation window assembly 500 includes a rectangular frame 501. A rectangular glass window 502 is fixedly installed in the rectangular frame 501. The rectangular glass window 502 is used to observe outside the door.

[0017] In practical applications, the door panel body 300 rotates on the door frame body 100 via two hinges 200. The rectangular slot 400 on the door panel body 300 facilitates the installation of the observation window assembly 500. The observation window assembly 500 also facilitates the disassembly of the rectangular frame 501 and the rectangular glass window 502 within the observation window assembly 500, thereby increasing the disassembly speed of the rectangular frame 501 and the rectangular glass window 502.

[0018] Please see Figure 2 - Figure 4 As shown, rotating shafts 503 are fixed on both sides of the rectangular glass window 502 near the bottom, and the two rotating shafts 503 are symmetrically arranged. A U-shaped limiting block 504 is provided on the outer side of each rotating shaft 503. The two U-shaped limiting blocks 504 are fixedly connected to the inner walls of both sides of the rectangular slot 400. Sliding plates 505 are fixedly connected to the inner walls of both sides of the rectangular slot 400. The two sliding plates 505 are near the top inner wall of the rectangular slot 400. Sliding grooves 506 are provided on opposite sides of the two sliding plates 505, and the two sliding grooves 506 are symmetrically arranged. An L-shaped receiving plate 507 is fixedly connected between the two sliding plates 505. Two circular holes 508 are provided on the top side, and the two circular holes 508 are symmetrically arranged. A sliding pin 509 is slidably connected in each circular hole 508. One end of the two sliding pins 509 is fixedly connected to the same L-shaped clamping plate 511. A compression spring 512 is sleeved on the outside of each sliding pin 509. The top end of the compression spring 512 is fixedly connected to the inside of the L-shaped receiving plate 507, and the bottom end of the sliding pin 509 is fixedly connected to the top side of the L-shaped clamping plate 511.

The two sliding limit blocks 513 are slidably connected in two sliding grooves 506 respectively.

[0019] In practical applications, the observation window assembly 500 facilitates the disassembly of the rectangular frame 501 and the rectangular glass window 502. First, the L-shaped clamping plate 511 is pushed vertically upwards. Simultaneously, the two sliding limit blocks 513 and the two sliding grooves 506 guide the L-shaped clamping plate 511, and the L-shaped clamping plate 511 compresses the two compression springs 512. Conversely, the L-shaped clamping plate 511 can compress the top side of the rectangular frame 501 through the two compression springs 512, thus... The rectangular frame 501 is snapped into the rectangular slot 400. Then, the rectangular frame 501 and the rectangular glass window 502 are taken out from the rectangular slot 400. At the same time, the two rotating shafts 503 slide along the U-shaped limiting blocks 504. The two U-shaped limiting blocks 504 are used to limit the two rotating shafts 503, which makes it convenient for workers to replace or clean the rectangular frame 501 and the rectangular glass window 502, thus solving the problem of the difficulty in disassembling the rectangular frame 501 and the rectangular glass window 502.
