Description

Technical Field

[0001] This utility model relates to the technical field of screen windows, and in particular to a removable screen box for roller blind screen windows. Background Technology

[0002] Roller blinds are a modern home furnishing product that combines practicality and aesthetics. They are widely used in homes, offices, and commercial spaces for mosquito prevention, dust control, ventilation, and privacy protection. Roller blinds mainly consist of a screen frame, a roller structure, and a pull rod. The screen frame is composed of a screen box and three profiles. The roller structure is located inside the screen box of the screen frame and includes a screen rolled up on a curved surface. The upper and lower ends are connected to the screen box through bases, allowing the roller structure to rotate between the two bases to release or retract the screen.

[0003] Traditional roller blind screens have a very simple structure, consisting of a screen box with a curtain opening, a roller mechanism, and various profiles. During installation, the roller mechanism is first installed inside the screen box, and the screen box and profiles are connected to form the screen frame. Then, the screen box and profiles are fixed to the window frame using adhesive or screws. However, after long-term use, the screen mesh tends to loosen due to insufficient tension, and it easily attracts dust, hair, and other impurities, requiring frequent cleaning. But the roller blind installation structure makes it difficult to remove the roller mechanism, thus affecting the later maintenance and cleaning of the screen mesh. (Refer to the utility model patent with publication number CN219387766U). As can be seen from the patent "A Roller Shutter System for Roller Blinds", a split-type screen box structure has emerged. The screen box is set as a split structure composed of an inner frame and an outer frame, thus hiding the roller structure inside the screen box. The screen is passed through the curtain opening. When the entire screen window is fixedly installed, the roller structure can be removed by removing the outer frame, thus enabling maintenance of the screen. However, in current roller blind screen windows, the inner frame and outer frame of the screen box are fixedly connected by screws. Each time it is disassembled, the connecting screws must be removed first, which is still inconvenient. Therefore, how to quickly disassemble the roller structure is a technical problem that the industry urgently wants to solve. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] As attached Figure 1-7 As shown, this utility model discloses a removable screen box for a roller blind screen, comprising a screen box 1 and a roller structure 2. The screen box 1 includes an outer frame 4 and an inner frame 5 for connecting to the mounting surface, which represents the window frame. The inner frame 5 has a base 11 at both ends, and the outer frame 4 has a base 12 at both ends. The base 11 is snapped onto the base 12. The roller structure 2 is installed between the two bases 12. By setting the screen box 1 as a separate structure of the inner frame 5 and the outer frame 4, with the base 11 at the end of the inner frame 5 and the base 12 at the end of the outer frame 4, and the roller structure 2 installed between the bases 12, the roller structure 2 and the outer frame 4 are integrated. The roller structure 2 includes a spring shaft, and the two bases 12 are respectively provided on their facing sides. There is a connecting post 122, which is rotatably connected to the spring shaft. An adjustment structure, including a screw and a gear, is also provided on the base 12 at the bottom. By turning the screw, the gear rotates, and the gear drives the spring inside the spring shaft to twist, thereby adjusting the tension of the spring shaft. This belongs to the existing roller structure 2. During installation, the inner frame 5 is fixedly connected to the mounting surface of the window frame, etc. Then, the base 11 at the end of the inner frame 5 and the base 12 at the end of the outer frame 4 are interlocked, so that the outer frame 4 and the inner frame 5 are combined to form a screen box 1, thereby hiding the roller structure 2 inside the screen box 1. When cleaning or maintenance is required, the interlocking connection between the base 11 and the base 12 can be disassembled to separate the outer frame 4 and the inner frame 5, so that the outer frame 4 and the roller structure 2 can be removed together, achieving the effect of quick disassembly of the roller structure 2.

[0022] Specifically, the side of base 11 facing base 12 (a) has a slot 110, and the side of base 12 facing base 11 (b) has a locking strip 121. The locking strip 121 and the slot 110 work together to achieve a locking mechanism. Specifically, the locking strip 121 is cylindrical, and the slot 110 matches the locking strip 121. The opening width of the slot 110 is smaller than the diameter of the locking strip 121, allowing the locking strip 121 to be securely engaged after entering the slot 110, preventing it from slipping out of the slot 110. The opening falls out. Based on this, both the a base 11 and the b base 12 are made of plastic. Plastic has good elasticity and toughness, which is more conducive to the snapping of the a base 11 and the b base 12. The locking and releasing of the clip strip 121 and the slot 110 can be achieved through elastic deformation. The inner frame 5 and the outer frame 4 are both made of metal. This belongs to the prior art. In order to ensure the overall uniformity of the screen window and the uniformity with the window frame, it is usually made of the same material as the window frame, which is aluminum profile or aluminum alloy profile.

[0023] Specifically, the a-base 11 and b-base 12 are respectively provided with protrusions 111, and are respectively inserted into the end faces of the inner frame 5 and the outer frame 4 through the protrusions 111. The a-base 11 is provided with an a-through hole 115, the inner frame 5 is provided with a first connecting hole 500 corresponding to the a-through hole 115, the b-base 12 is provided with a b-through hole 123, and the outer frame 4 is provided with a second connecting hole 400 corresponding to the b-through hole 123. Figure 2 , 3 6. The end faces of the inner frame 5 and the outer frame 4 have frame openings. When the protrusions 111 of the base a and base b are inserted into the frame openings of the inner frame 5 / outer frame 4, the protrusions 111 are in a state of being tightly against the inner side of the frame opening, which plays a role in temporary fixation. At the same time, screws are inserted through the through hole a 115 and connected to the first connecting hole 500, and screws are inserted through the through hole b 123 and connected to the second connecting hole 400, so as to fix the base a 11 at both ends of the inner frame 5 and fix the base b 12 at both ends of the outer frame 4.

[0024] Specifically, it also includes a track profile 6 and a side post profile 7. The outer frame 4 has a curtain opening 100 on the side facing the track profile 6. The track profile 6 is used for the smooth sliding of the mesh 3. The side post profile 7 is set on the opposite side of the mesh box 1. The curtain opening 100 is used for the mesh 3 to enter and exit the mesh box 1. It should be noted that the curtain opening 100 is set on the outer frame 4, specifically on the side of the outer frame 4 close to the inner frame 5. That is, one side of the outer frame 4 does not contact the inner frame 5, and a gap is reserved to serve as the curtain opening 100.

[0025] Specifically, one side of the a-base 11 is provided with a pin 116 for connecting to the track profile 6. The pin 116 is connected to the track profile 6 by screws. The track profile 6 and the side column profile 7 are both aluminum profiles with cavities. The pin 116 on the a-base 11 is used to engage the cavity of the track profile 6 to facilitate the subsequent connection between the gauze box 1 and the track profile 6. The pin 11 is connected to the track profile 6 by screws. The a-base 11 is located at both ends of the inner frame 5. There are two track profiles 6, which are placed horizontally at the top and bottom respectively. One end of the two track profiles 6 is connected to the adjacent a-base 11, and the other end is connected to both ends of the side column profile 7 respectively.

[0026] By setting the screen box 1 as a split structure, including an outer frame 4 and an inner frame 5, the inner frame 5 and the outer frame 4 are not directly connected. The inner frame 5 is provided with base 11 at both ends, and the outer frame 4 is provided with base 12 at both ends. The base 11 and base 12 are interlocked to form the screen box 1 by the interlocking of the inner frame 5 and the outer frame 4. The roller structure 2 is set between the base 12. The roller screen also includes track profile 6 and side post profile 7. After the screen box 1 is assembled, one end of the two track profiles 6 is inserted into the pin 116 of the base 11 and connected to the track profile 6 and the pin 116 by screws to realize the connection and fixation of the screen box 1 and the track profile 6. The side post profile 7 and the track profile 6 are also connected by screws. The specific connection structure can refer to the existing roller screen. At this time, the roller screen is fully assembled.

[0027] To securely install roller blind screens onto the window frame, screws or adhesive are typically used. During installation, adhesive is first applied to the side of the inner frame 5, track profile 6, and side post profile 7 facing the window frame, and then they are adhered to the frame. If screws are used, the connection between base 12 (b) and base 11 (a) is first disassembled, and the outer frame 4 is removed. The inner frame 5 is then secured to the window frame with screws. Similarly, the side post profile 7 and track profile 6 are installed onto the window frame with screws, and then the outer frame 4 is reinstalled. When the roller structure 2 needs to be disassembled, simply remove base 12 from base 11, separating the outer frame 4 from the inner frame 5, thus allowing for quick disassembly of the outer frame 4 and the roller structure 2.

[0028] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
