Technical Field

[0001] This utility model belongs to the field of door technology, and in particular relates to a secondary window structure for a burglarproof door. Background Technology

[0002] The secondary window on the door panel mainly serves the purpose of lighting and ventilation. It is supported and opened by a structure such as a connecting rod, wind hook, and hydraulic rod, while the window panel is fixed to the window frame by a latch and buckle.

[0003] Chinese patent CN206769694U discloses a secondary window for a security door, which includes a window frame, a connecting hinge, a sliding track, a window sash, and a latch. The latch and buckle are located on the outer side of the window sash and frame and protrude, making the design less aesthetically pleasing and unsuitable for the modern decoration requirements of a neat and aesthetically pleasing door design.

[0004] Therefore, a secondary window structure for security doors is needed to make the locking point between the secondary window sash and the window frame aesthetically pleasing and easy to operate. Utility Model Content

[0005] The purpose of this utility model is to provide a secondary window structure for a security door to solve the problems existing in the background art.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A security door secondary window structure includes a door leaf, a window opening and a secondary window, wherein the secondary window includes a window frame and a glass panel, and the window frame is provided with latch assemblies on both sides, wherein the latch assemblies are embedded in the window frame;

[0008] The latch assembly includes a mounting base, a lever, a connecting rod assembly, and a pin; the window opening is provided with a hole corresponding to the position of the pin.

[0009] The lever is located on the front of the mounting base, and one end of the lever is hinged to the mounting base. The connecting rod assembly is located on the back of the mounting base. The connecting rod assembly includes a U-shaped frame and a connecting rod. The slot of the U-shaped frame is hinged to the lever, and the side of the U-shaped frame away from the lever is hinged to the middle of the connecting rod. The lower end of the connecting rod is connected by a pin.

[0010] Furthermore, the connecting rod has an arc-shaped section near the U-shaped frame, and both the upper and lower ends of the connecting rod are connected by the limiting rod of the mounting base.

[0011] Furthermore, the end of the lever is provided with a semi-circular lever piece, and the mounting base is provided with a groove corresponding to the position of the lever.

[0012] Furthermore, the mounting base is provided with a decorative panel, which is snapped into the window frame.

[0013] Furthermore, the secondary window is sized to match the window opening, and the top of the secondary window is hinged to the top of the window opening.

[0014] Furthermore, a support assembly is provided between the secondary window and the window opening, and the support assembly adopts a wind hook or a hydraulic rod.

[0015] The beneficial effects of this utility model are:

[0016] The pin assembly has a simple structure and is easy to operate. Simply pull the lever to lock or release the pin from the socket.

[0017] Embedded latch components ensure a smooth and aesthetically pleasing window frame. When the window frame is locked to the window opening, a decorative plate can be installed on the outside of the mounting base. The decorative plate is then engaged with the window frame to further conceal the latch components and maintain the window frame's appearance. Attached Figure Description

Detailed Implementation

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] See Figures 1-5 This utility model provides a technical solution:

[0026] like Figures 1-3 As shown, a security door secondary window structure includes a door leaf 1, a window opening 2, and a secondary window 3. The secondary window 3 includes a window frame 31 and a glass panel 32. The size of the secondary window 3 matches that of the window opening 2. The top of the secondary window 3 is hinged to the top of the window opening 2. By rotating the secondary window 3, the window opening 2 can be opened to allow ventilation and light.

[0027] Meanwhile, a support component 5 is provided between the secondary window 3 and the window opening 2. It is supported by a support frame to adjust the opening and closing distance of the secondary window 3 and prevent the opened secondary window 3 from falling back. The support component 5 adopts a wind hook or a hydraulic rod.

[0028] like Figure 1 and Figure 2 As shown, the window frame 31 is provided with latch assemblies 4 on both sides, and the latch assemblies 4 are embedded in the window frame 31;

[0029] Specifically, such as Figure 4 and Figure 5 As shown, the latch assembly 4 includes a mounting base 41, a lever 42, a connecting rod assembly, and a pin 44. The window opening is provided with a socket 21 corresponding to the position of the pin 44.

[0030] Through the above technical solution, the embedded latch assembly 4 can ensure that the window frame 31 has a flat and beautiful appearance. When the window frame 31 is locked with the window opening, a decorative plate can be provided on the outside of the mounting base 41. The decorative plate is engaged with the window frame 31 to further hide the latch assembly 4 and ensure the beauty of the window frame 31.

[0031] Specifically: the lever 42 is located on the front of the mounting base 41, one end of the lever 42 is hinged to the mounting base 41, the connecting rod assembly is located on the back of the mounting base 41, the connecting rod assembly includes a U-shaped frame 45 and a connecting rod 46, the slot of the U-shaped frame 45 is hinged to the lever 42, the side of the U-shaped frame 45 away from the lever 42 is hinged to the middle of the connecting rod 46, and the lower end of the connecting rod 46 is connected to the pin 44.

[0032] With the above technical solution, when it is necessary to loosen the window frame 31 and the window opening 2, by pulling the lever 42, the lever 42 flips upward. At this time, the U-shaped frame 45, which is hinged to the lever 42, will also flip upward, thereby driving the connecting rod 46, which is hinged to the U-shaped frame 45, to move upward. This, in turn, causes the pin 44, which is connected to the connecting rod 46, to be lifted upward from the socket 21, thus unlocking the window frame 31 and the window opening 2. Conversely, pressing the pin downward will lock the pin 44 and the socket 21.

[0033] The entire pin assembly 4 has a simple structure and is easy to operate. Simply pull the lever 42 to lock and release the pin 44 from the socket 21.

[0034] Furthermore, the connecting rod 46 is provided with an arc-shaped segment 47 near the U-shaped frame 45, and the upper and lower ends of the connecting rod 46 are connected by the limiting rod 48 of the mounting base 41.

[0035] Through the above technical solution, the arc segment 47 is used to avoid interference when the lever 42 rotates, and the upper and lower ends of the connecting rod 46 are limited by the limiting rod 48, which can ensure that the connecting rod 46 can only move in the up and down direction.

[0036] Furthermore, the end of the lever 42 is provided with a semi-circular lever 43, and the mounting base 41 is provided with a groove 49 corresponding to the position of the lever 42.

[0037] Through the above technical solution, the semi-circular paddle 43 is convenient for people to paddle with their fingers, and the groove 49 also makes it convenient for fingers to be inserted for operation.

[0038] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model 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 concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
