[0002] Door and window hinges are accessories used to connect the window frame and the window sash. Traditional door and window connections usually require drilling holes in the window sash and then tightening screws. When the screen needs to be removed for cleaning or replacement, the screws must be removed, which is cumbersome and time-consuming. Repeated disassembly and assembly can easily lead to stripped screws or frame damage, affecting structural stability and service life. In addition, in the past, casement screens were directly installed with window hinges. The sash mounting parts of the two hinges were inserted into the upper and lower ends of the screen sash and fixedly connected. The frame mounting parts of the two hinges were placed into the window frame profile groove and fixedly connected. When disassembling, the screen sash and hinges were first removed from the window frame as a whole, and then the hinges were removed from the screen sash. This installation structure is inconvenient for installation and disassembly.

[0003] Currently, a method for quick disassembly using a locking mechanism has emerged on the market. However, the unlocking mechanism of this type of structure is relatively complex in design, has many parts, and requires precision machining, which increases production costs.

Detailed Implementation

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] It should be understood that the door leaf includes an upper profile, a lower profile, and a side profile for connecting the window frame. The upper profile, lower profile, and side profile are all provided with profile grooves, which are T-shaped grooves. These are all existing structures, and you can refer to the existing casement window structure for details.

[0020] Example 1 like Figures 1 to 7The diagram illustrates a quick-assembly and disassembly structure for a window sash without drilling. It includes a base assembly 1 and an insert plate assembly 2. The base assembly 1 has a first abutment part 3, and the insert plate assembly 2 has a second abutment part 4. The base assembly 1 is inserted into the lower end of the window sash 5, and the insert plate assembly 2 is inserted into the side of the window sash 5. The first abutment part 3 and the second abutment part 4 abut against each other. The insert plate assembly 2 also has a locking part 6 for locking the insert plate assembly 2 to the window sash 5. The base assembly 1 is inserted into a profile groove at the lower end of the window sash 5, and the insert plate assembly 2 is inserted into a profile groove on the side of the window sash 5. The first abutment part 3 on the base assembly 1 and the second abutment part 4 on the insert plate assembly 2 abut against each other. A hinge is connected to the bottom surface of the base assembly 1, and the other end of the hinge is connected to the window frame, thus achieving the installation connection between the window sash and the window frame. The insert plate assembly 2 is locked in the profile groove on the side of the window sash 5 by the locking part 6. When it is necessary to disassemble the window sash 5, simply loosen the locking part 6 to achieve quick disassembly. There is no need to drill holes in the window sash 5 to install screws, avoiding problems such as frame wear caused by repeated disassembly and assembly. In addition, the insert assembly 2 has a simple structure, reducing processing difficulty and production costs.

[0021] Specifically, the base assembly 1 in this embodiment includes a window sash connecting plate 7 on the upper layer and a hinge connecting plate 8 on the lower layer. The window sash connecting plate 7 and the hinge connecting plate 8 are fixedly connected. The base assembly 1 is set as a double-layer structure, which has stronger overall load-bearing capacity and higher stability.

[0022] Preferably, the hinge connecting plate 8 has an upward folding block 12, and the window sash connecting plate 7 has an opening 13 corresponding to the folding block 12. The folding block 12 passes through the opening 13 and bends away from the first abutment 3. The folding block 12 is integrally formed by the hinge connecting plate 8 and folds upward. After passing through the opening 13 on the window sash connecting plate 7, it wraps around the window sash connecting plate 7 away from the first abutment 3, fixing the window sash connecting plate 7 and the hinge connecting plate 8 together. During use, the window sash connecting plate 7 is not easy to fall off the hinge connecting plate 8.

[0023] In this embodiment, multiple limiting parts 14 are provided between the window sash connecting plate 7 and the hinge connecting plate 8, forming a slot structure between them. The limiting parts 14, together with the window sash connecting plate 7 and the hinge connecting plate 8, form a slot structure that limits the profile groove that inserts into the base assembly 1, preventing the window sash from swaying left and right. The limiting parts 14 can be downwardly recessed portions formed by directly stamping the window sash connecting plate 7, upwardly protruding portions formed by directly stamping the hinge connecting plate 8, or additional structures welded between the window sash connecting plate 7 and the hinge connecting plate 8.

[0024] Specifically, the locking part 6 includes a locking hole 15 opened at the upper end of the insert plate assembly, and a locking member 16 is inserted into the locking hole 15. The locking member 16 can be a set screw, and the locking hole 15 is a screw hole. The set screw presses against the bottom wall of the profile groove, thereby locking the insert plate assembly 2 onto the window sash 5. Conversely, when disassembling, after loosening the set screw, the second abutting part 4 of the insert assembly 2 is separated from the first abutting part 3 of the base assembly 1, and the window sash 5 can be removed.

[0025] In this embodiment, the second abutting part 4 is an insert plate located at the lower end of the insert plate assembly 2, and the first abutting part 3 is a slot located at one end of the window sash connecting plate 7 and corresponding to the insert plate. The window sash connecting plate 7 is provided with a slot, and the insert plate is directly inserted into the slot. The lower end of the insert plate abuts against the hinge connecting plate 8, and the front and rear sides of the insert plate abut against the slot, so that the insert plate assembly 2 and the base assembly 1 can be stably inserted into the profile groove of the window sash 5.

[0026] Specifically, in this embodiment, two upward-facing abutments 9 are symmetrically provided on both sides of the window sash connecting plate 7; when the base assembly 1 is inserted into the profile groove of the window sash 5, the protrusion formed by the abutment 9 abuts against the end of the bottom of the profile groove, preventing the base assembly 1 from falling off the profile groove.

[0027] Example 2 The difference between Embodiment 2 and Embodiment 1 of this utility model is that: the second abutting part 4 in this embodiment is a baffle plate disposed at the lower end of the insert plate assembly 2, and a connecting piece 10 is disposed at the upper end of the baffle plate. The baffle plate protrudes from the connecting piece 10. The first abutting part 3 is a abutting piece disposed at the upper end of the window sash connecting plate 7. The abutting piece extends into the gap formed between the baffle plate and the window sash 5. One side of the abutting piece abuts against the baffle plate, and the other side of the abutting piece abuts against the window sash 5. The abutting piece is fixed by the baffle plate and the profile groove, so that the base assembly 1 is fixed at the lower end of the window sash 5 and is not easy to move. The insert plate assembly 2 is fixed to the side of the window sash 5 by the locking part 6, thereby achieving double fixation of the base assembly 1 and the insert plate assembly 2.

[0028] Preferably, in this embodiment, a boss 11 is formed between the connecting piece 10 and the baffle, and the upper end of the abutment abuts against the lower end of the boss 11; the boss 11 abuts against the upper end of the abutment, so that the abutment is more firmly fixed in the gap formed between the boss 11, the baffle and the bottom wall of the profile groove, thereby making the base assembly 1 less prone to back and forth shaking and enhancing stability.

[0029] It is worth noting that in this embodiment, the abutment and the window sash connecting plate 7 are integrally bent into shape at one end; the integrated structure avoids the disadvantages of weak welding points or screw connections in traditional split structures, reduces the risk of breakage, and makes the connection between the insert plate assembly 2 and the base assembly 1 more stable.

[0030] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
