Description

Technical Field

[0001] The invention relates to the field of roller screen doors, in particular to an adjustable roller screen door and mounting accessories thereof. Background Art

[0002] Sliding doors are commonly used, referring to doors that can be pushed or pulled. The door leaf is pushed and pulled to open and close vertically. To provide ventilation and dust protection when the sliding door is open, a sliding screen is often installed. Furthermore, to facilitate the installation of a sliding screen, a corresponding sliding structure is often incorporated into the door frame.

[0003] However, conventional sliding screen doors also have certain disadvantages. The main one is that they will inevitably block part of the door leaf, making it impossible to pass through (unless the sliding structure extends into the wall, allowing the sliding screen door to slide into the wall); in addition, the sliding screen door cannot be retracted and must be removed as a whole. Roller screen doors can effectively overcome these disadvantages, but in contrast, using a roller screen door requires a separate design for the corresponding sliding door frame, otherwise it will be difficult to install and put into use.

[0004] Therefore, without independently designing a corresponding sliding door frame, a roller screen door that is compatible with most of the sliding doors currently available on the market or installation accessories for universal assembly of roller screen doors is needed to overcome the differences in the cross-sectional structure of door frame profiles among different suppliers (differences in the cross-sectional structure of door frame profiles will result in different height dimensions of the inner edge of the door frame, and the spatial structure provided for the installation of the screen door will also be different) to meet the compatible installation requirements of the roller screen door.

[0064] In order to make the technical solution of the present invention clearer and more specific, the present invention is further described below in conjunction with embodiments. Any equivalent replacement of the technical features of the technical solution of the present invention and any solution derived by conventional reasoning shall fall within the scope of protection of the present invention.

[0065] Example 1

[0066] like Figures 1-6 As shown, the present embodiment discloses an adjustable roller screen door, which is suitable for sliding doors and is used to replace old-fashioned sliding screen doors. The adjustable roller screen door includes a roller screen door 2, which includes a screen box 28, a screen 45 and a screen handle 29. The screen 45 is elastically rolled up in the screen box 28, and one end of the screen is connected to the screen handle 29. Specifically, the present embodiment is provided with end covers 1 at both ends of the screen box 28, and the end covers 1 include a sleeve 3 and a positioning plate 4. The positioning plate 4 and the sleeve 3 are an integrated structure. The sleeve 3 is sleeved on the end of the roller screen door 2, and a yarn outlet 8 for the roller screen door 2 to discharge yarn is opened on one side of the sleeve 3 to facilitate the pulling out and retraction of the mesh yarn. At the same time, in the present embodiment, the positioning plate 4 is arranged on the same side as the yarn outlet 8, and a strip-shaped elastic lock tongue 9 is provided on the side of the positioning plate 4.

[0067] The opening and closing of the roller screen door 2 is achieved by pushing and pulling the screen handle 29. In order to guide the push-pull direction of the screen handle 29, the end cover 1 of this embodiment is connected to the screen slide 32 through the positioning plate 4. The screen slide 32 is provided with an end cover connecting groove 38 for connecting the end cover 1 and the screen slide 32 and a handle slide groove 39 for guiding the push-pull direction of the screen handle 29.

[0068] Specifically, the positioning plate 4 is plugged into one end of the end cover connecting groove 38, thereby realizing the connection between the mesh slide 32 and the end cover 1; at the same time, the positioning plate 4 of this embodiment is clearance-matched with the end cover connecting groove 38, and a bayonet 33 is opened on the outer wall of one end where the end cover connecting groove 38 is connected to the positioning plate 4, and the bayonet 33 is engaged with the elastic locking tongue 9 to ensure the connection strength and stability between the mesh slide 32 and the end cover 1; handle sliders 40 are provided on the upper and lower end sides of the mesh handle 29, and the handle slider 40 is slidingly engaged with the handle slide groove 39, thereby realizing the sliding connection between the mesh handle 29 and the mesh slide 32, and guiding the push and pull direction of the mesh handle 29.

[0069] An adjustable roller screen door of the present embodiment is used to replace the old sliding screen door and is installed at the sliding door frame. The screen door can be opened and closed as needed and will not hinder the normal passage of the door leaf when not in use.

[0070] Example 2

[0071] like Figure 3-Figure 5 As shown, the embodiment discloses an adjustable roller screen door, wherein the elastic lock tongue 9 is provided with a lock tongue protrusion 20, which cooperates with the bayonet 33 to achieve a locking connection function; in addition, the elastic lock tongue 9 can be provided on one side, or can be provided on the other side. Figure 5 The double-sided setting is shown. Under the condition of the same material specifications, the elastic lock tongue 9 set on one side is better than the elastic lock tongue 9 set on both sides in maintaining the structural strength of the positioning plate 4 and ensuring the connection stability of the end cover 11 and the screen slide 32. As for the locking effect, the latter is better, but there is also a problem of difficulty in unlocking, especially when applied to the installation of the roller screen door 2, one side of the installed roller screen door 2 will be close to the sliding door leaf, which increases the difficulty of unlocking the elastic lock tongue 9 on this side. On the whole, it is more practical to use the elastic lock tongue 9 on one side, and the setting position of the elastic lock tongue 9 is on the side away from the sliding door leaf;

[0072] At the same time, in this embodiment, an elastic strip 21 is provided between the elastic locking tongue 9 and the positioning plate 4 , and the elastic locking tongue 9 is elastically connected to the positioning plate 4 via the elastic strip 21 , and there is at least one elastic strip 21 .

[0073] Example 3

[0074] like Figure 1 、 Figure 2 and Figure 6 As shown, an adjustable roller screen door of the present embodiment has an adjustable function, and the installation scheme of the roller screen door 2 can be adjusted according to the length specification of the roller screen door 2 to achieve the purpose of adapting to the sliding door frame. Specifically, the end cover 1 is divided into an upper end cover 101 sleeved on the upper end of the screen box 28 and a lower end cover 102 sleeved on the lower end of the screen box 28 according to the sleeve position. The screen slide 32 is divided into an upper screen slide 321 connected to the upper end cover 101 and a lower screen slide 322 connected to the lower end cover 102. The handle slide 39 is composed of adjacent gap slides 43 and heightened slides 44. The height of the gap slide 43 in the vertical direction is less than the height of the heightened slide 44 in the vertical direction. The handle slider 40 slides with the gap slide 43 or the heightened slide 44.

[0075] The handle slider 40 at the upper end of the mesh handle 29 is an upper handle slider 41, the handle slider 40 at the lower end of the mesh handle 29 is a lower handle slider 42, the gap chute 43 and the heightening chute 44 at the upper mesh slide 321 are respectively an upper gap chute 431 and an upper heightening chute 441, the gap chute 43 and the heightening chute 44 at the lower mesh slide 322 are respectively a lower gap chute 432 and a lower heightening chute 442. At this time, there are four schemes for the sliding cooperation between the handle slider 40 and the handle slide 39 (such as Figure 6 ), specifically as follows;

[0076] Q1. The upper handle slider 41 is slidably disposed in the upper heightened chute 441 , and the lower handle slider 42 is slidably disposed in the lower clearance chute 432 ;

[0077] Q2. The upper handle slider 41 is slidably disposed in the upper heightened chute 441 , and the lower handle slider 42 is slidably disposed in the lower heightened chute 442 ;

[0078] Q3. The upper handle slider 41 is slidably disposed in the upper clearance groove 431 , and the lower handle slider 42 is slidably disposed in the lower clearance groove 432 ;

[0079] Q4. The upper handle slider 41 is slidably disposed in the upper clearance chute 431 , and the lower handle slider 42 is slidably disposed in the lower heightened chute 442 ;

[0080] Under these four solutions, the upper end cover 101 and the lower end cover 102 will not be separated from the upper and lower ends of the mesh box 28;

[0081] When the height of the sliding door frame remains unchanged, the selection can be made according to the vertical length of the roller screen door 2; when the vertical length of the roller screen door 2 is at its shortest (equal to the vertical length between the upper gap chute 431 and the lower gap chute 432, recorded as d1), then the Q3 solution is applicable; when the vertical length of the roller screen door 2 is at its longest (less than or equal to the vertical length between the upper heightening chute 441 and the lower heightening chute 442, and greater than the vertical length between the upper heightening chute 441 and the lower gap chute 432, recorded as d2), then the Q3 solution is applicable. When the vertical length of the roller screen door 2 is moderate (greater than the vertical length between the upper gap chute 431 and the lower gap chute 432, and less than or equal to the vertical length between the upper and lower gap chute 432 or the vertical length between the upper gap chute 431 and the lower and lower heightened chute 442, denoted as d3), the Q1 or Q4 solution is applicable.

[0082] Similarly, it is easy to see that when the vertical length of the roller screen door 2 is constant, the vertical length of the adjustable roller screen door can be adjusted by selecting the sliding cooperation mode of the handle slider 40 and the handle slide groove 39 to adapt to sliding doors with different door frame heights.
