DETAILED DESCRIPTION

[0023] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0024] See also Figure 1-3 The utility model provides a technical solution: a key structure device for anti-theft doors and windows, including a frame 1, door and window outer frames 2 are symmetrically hinged on both sides of the interior of the frame 1, glass 3 is sealed and fixedly connected to the inner sides of the door and window outer frames 2, limiting grooves 4 are arranged on both sides of the upper end surface and the lower end surface of the door and window outer frames 2, circular grooves 5 are arranged at the positions corresponding to the limiting grooves 4 on the upper and lower sides of the inner wall of the frame 1, limiting blocks 6 are slidably arranged inside the circular grooves 5, and the limiting blocks 6 are plugged into the corresponding limiting grooves 4.

[0025] One end of the limiting block 6 corresponding to the limiting groove 4 is arranged as an inclined surface.

[0026] Rectangular holes 7 are provided at positions on the front side of the frame 1 corresponding to the circular grooves 5 , and switch components for driving the limit blocks 6 to move are provided inside the rectangular holes 7 .

[0027] The switch assembly includes a moving rod 8 , one end of which is fixedly connected to the limit block 6 , a spring 9 is fixedly connected to the top of the limit block 6 , and the other end of the spring 9 is fixedly connected to the inside of the circular groove 5 .

[0028] A locking assembly is provided on the side where the front end faces of the two door and window outer frames 2 are close to each other, and the locking assembly includes a first fixing rod 12 and a second fixing rod 13. The first fixing rod 12 is fixedly installed on the front end face of one of the door and window outer frames 2, and the end of the first fixing rod 12 facing away from the door and window outer frame 2 is fixedly connected to a limiting plate 14, and a rectangular groove 15 is provided on the limiting plate 14. The second fixing rod 13 is fixedly installed on the front end face of the other door and window outer frame 2, and a locking block 16 is rotatably installed on the end of the second fixing rod 13 facing away from the door and window outer frame 2, and the locking block 16 cooperates with the rectangular groove 15.

[0029] The door and window outer frames 2 are hinged to the inner side walls of the frame 1 through hinges.

[0030] In order to facilitate opening of doors and windows, a connecting block 10 is fixedly connected to one end of the moving rod 8 away from the limiting block 6 , and the connecting blocks 10 on the upper and lower sides are connected in series through a connecting rod 11 .

[0031] When closing the doors and windows, since the bottom end of the limit block 6 is set as an inclined surface, the door and window outer frame 2 pushes the bottom end of the limit block 6 so that the limit block 6 enters the corresponding circular groove 5, causing the spring 9 to contract. When the limit groove 4 on the door and window outer frame 2 moves to the position corresponding to the limit block 6, the door and window are just closed at this time, and the spring 9 returns to its original state and drives the limit block 6 to move out of the circular groove 5, and then plugs into the corresponding limit groove 4, which limits the door and window outer frame 2, so that the four corners of the door and window outer frame 2 are limited, thereby achieving a good anti-pry effect.

[0032] When the door and window outer frame 2 is closed, the locking block 16 and the rectangular groove 15 are arranged in parallel, so that the locking block 16 can pass through the rectangular groove 15. After the door and window outer frame 2 is closed, the locking block 16 passes through the rectangular groove 15, and the locking block 16 is rotated so that the locking block 16 is perpendicular to the rectangular groove 15, and then the second fixing rod 13 is clamped with the limit plate 14, which plays a further locking role and improves the safety of the doors and windows.

[0033] When the door or window needs to be opened, the locking block 16 is rotated so that the locking block 16 is parallel to the rectangular groove 15, and the connecting rod 11 is moved. The connecting rod 11 drives the corresponding moving rod 8 to move, and then drives the limit block 6 to disengage from the inside of the limit groove 4, so that the door or window can be opened.

[0034] Working principle:

[0035] When in use, when closing the door and window, since the bottom end of the limit block 6 is set as an inclined surface, the door and window outer frame 2 pushes the bottom end of the limit block 6 so that the limit block 6 enters the corresponding circular groove 5, causing the spring 9 to contract. When the limit groove 4 on the door and window outer frame 2 moves to the position corresponding to the limit block 6, the door and window are just closed at this time, and the spring 9 returns to its original state and drives the limit block 6 to move out of the circular groove 5, and then plugs into the corresponding limit groove 4, which limits the door and window outer frame 2, so that the four corners of the door and window outer frame 2 are limited, thereby achieving a good anti-pry effect.

[0036] When the door and window outer frame 2 is closed, the locking block 16 and the rectangular groove 15 are arranged in parallel, so that the locking block 16 can pass through the rectangular groove 15. After the door and window outer frame 2 is closed, the locking block 16 passes through the rectangular groove 15, and the locking block 16 is rotated so that the locking block 16 is perpendicular to the rectangular groove 15, and then the second fixing rod 13 is clamped with the limit plate 14, which plays a further locking role and improves the safety of the doors and windows.

[0037] When the door or window needs to be opened, the locking block 16 is rotated so that the locking block 16 is parallel to the rectangular groove 15, and the connecting rod 11 is moved. The connecting rod 11 drives the corresponding moving rod 8 to move, and then drives the limit block 6 to disengage from the inside of the limit groove 4, so that the door or window can be opened.

[0038] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
