Description

Technical Field

[0001] This utility model relates to the field of inward window technology, specifically inward window technology. Background Technology

[0002] Inward-opening windows are windows that open inwards. The main characteristic of these windows is that they can be opened or tilted inwards by rotating a handle. Inward-opening windows are widely used in high-rise buildings due to their high security, dust and rain protection, and ease of cleaning. However, most inward-opening windows are locked together by only one locking point, which can lead to insufficient security in actual use, thus reducing the safety of the window.

[0003] During the design process of this utility model, the following problems were found in the existing technology: When using common inward-opening windows, the two window frames are mostly locked and closed by only one locking point. In actual use, the locking and closing is not secure enough, which cannot meet the needs of users and thus reduces the safety of inward-opening windows. Utility Model Content

An inner frame sealing part 107 is installed at one end of the inner frame body 103. An inner frame inner wall 108 is installed at one end of the inner frame sealing part 107.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 6 As shown, the inner frame outer wall 101, the outer wall connecting part 102 and the inner frame connecting part 105 are all made of imitation ceramic coating process and are all constructed by whole welding and whole spraying. The inner frame outer wall 101, the outer wall connecting part 102 and the inner frame connecting part 105 are all black. The interior of the inner frame outer wall 101 and the outer wall connecting part 104 form a threaded connection structure.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 6 As shown, the inner frame body 103 is made of alloy material, and the inner frame welding part 106 and the inner frame sealing part 107 are both made of brushed copper and are made of brushed copper. The inner frame inner wall 108 is made of whole frame spraying process and is entirely made of glass black.

[0026] In this embodiment, as Figure 1 and Figure 3 As shown, a square shaft 401 is installed in the center of the handle 4, and fixing screws 402 are installed at both the upper and lower ends of the handle 4. A connecting groove 501 is embedded in the center of the transmission device 5, and fixing grooves 502 are provided at both the upper and lower ends of the connecting groove 501. One end of the square shaft 401 is installed inside the connecting groove 501, and the fixing screws 402 and the fixing grooves 502 form a threaded connection structure.

[0027] In this embodiment, as Figure 1 and Figure 4 As shown, there are two inner window frames 1 in the outer frame 3. Multiple locking points 601 are evenly installed on one side of the transmission rod 6, and one end of the locking point 601 is engaged with a locking seat 602. The locking seat 602 is installed on one side of the other inner window frame 1.

[0028] In this embodiment, as Figure 1 and Figure 4 As shown, a transmission assembly 603 is installed at one end of the transmission rod 6, and a locking block 604 is installed inside the transmission assembly 603. A transverse connecting rod 605 is installed at one end of the transmission assembly 603, and a locking point 601 is installed inside the transverse connecting rod 605.

[0029] In this embodiment, as Figure 1 and Figure 5 As shown, the friction hinge 7 is a groove-free structure, and the maximum opening angle of the friction hinge 7 is eighty-eight degrees.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the inward-opening window operates as follows:

[0031] Firstly, the inner frame outer wall 101, outer wall connecting part 102, and inner frame connecting part 105 of the inward-opening window are all constructed with black imitation porcelain coating process through welding and spraying to ensure the aesthetic appearance of the inward-opening window. At the same time, the inner frame welding part 106 and the inner frame sealing part 107 are all made of brushed copper with a whole welding and brushing process, so that the welding and sealing parts contrast with the overall black exterior, increasing the color impact. Furthermore, the inner frame inner wall 108 inside the inner window frame 1 is made of glass black with a whole frame spraying process, further enhancing the overall aesthetics of the inward-opening window.

[0032] Subsequently, when the inward-opening window is in use, the handle 4 is rotated to drive the connecting groove 501 inside the transmission device 5 connected by the fixing screw 402, thereby driving the locking point 601 on the transmission rod 6 at both ends to separate from the locking seat 602 on the inner window frame 1 at the other end.

[0033] Then, under the action of the transmission component 603, the locking point 601 on the transverse connecting rod 605 is driven to separate from the locking seat 602 on the outer frame 3. The inner window frame 1 can be opened by the handle 4 under the action of the friction hinge 7. At the same time, the friction hinge 7 can effectively limit the opening range of the inner window frame 1.

[0034] When closing the inner window frame 1, the inner window frame 1 is pushed into the outer frame 3 by rotating the handle 4, so that the locking point 601 on the transmission rod 6 engages with the lock seat 602. At the same time, the locking block 604 in the transmission assembly 603 can effectively improve the safety of the inward-opening window.
