Description

Technical Field

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

[0002] Screens offer functions such as mosquito prevention, dust prevention, ventilation, and privacy protection, and are widely used in homes, offices, and commercial spaces. Roller screens are a type of screen, primarily consisting of a screen frame, a roller structure, and a handle. The screen frame is composed of a screen box and three profiles. The roller structure is located inside the screen box and is covered with screen mesh, which is then connected to the handle. Its main feature is that it can "hide" the screen mesh, maintaining the window's transparency and aesthetics. When people want to unfold the screen mesh, they can use the handle to pull it out and along the track to the side away from the screen box, where it is then secured with a lock. To retract the screen mesh, simply unlock the lock, and the spring within the roller structure will automatically return, causing the roller structure to rotate and automatically roll up the screen mesh back into the screen box. However, due to the existing roller structure design of roller screens, this type of screen only has two operating states, and users cannot control the opening range of the screen mesh according to their needs, making it impossible to achieve "pull and stop at will."

Detailed Implementation

[0021] 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.

[0022] As shown in the attached figure, this utility model discloses a roller blind screen window, including an upper rail 1, a lower rail 2, and a handle rod 3, as well as a screen box and side profiles. The screen box is equipped with a roller structure, which includes a screen and is connected to the handle rod 3 through the screen. The handle rod 3 is provided with a hanging wheel assembly 4 slidably connected to the upper rail 1 and a bottom wheel assembly 5 slidably connected to the lower rail 2 at both ends. The hanging wheel assembly 4 includes an abutment member 41 that elastically abuts against the upper rail 1, and the bottom wheel assembly 5 includes a bbutment member 51 that elastically abuts against the lower rail 2. The abutment member 41 and the bbutment member 51 are made of plastic material. By using abutment 41 and bbutment 51 provided on the hanging wheel assembly 4 and the bottom wheel assembly 5, respectively, they elastically abut against the upper rail 1 and the lower rail 2. When the user pulls the handle 3, abutment 41 and bbutment 51 remain close to the inner wall of the upper rail 1 and the lower rail 2 and slide. When the user stops pulling, abutment 41 and bbutment 51 abut against the upper rail 1 and the lower rail 2, using their friction to counteract the rewinding force of the roller structure, thereby positioning the handle 3 in any area of ​​the pulling line and achieving the effect of "pull and stop".

[0023] Specifically, the hanging wheel assembly 4 includes an upper base 42 connected to the handle rod 3. A boss 421 is provided in the middle of the top of the upper base 42, and upper hanging wheels 43 are provided on both sides of the boss 421. The abutment member 41 is installed on the top of the boss 421 and protrudes upward from the upper hanging wheels 43. The abutment member 41 includes a mounting block 411 and first top feet 412 symmetrically arranged on the mounting block 411. A first elastic member 413 is provided between the first top feet 412. The upper hanging wheels 43 are rotatably mounted on both sides of the boss 421 via pins. The mounting block 411 has through holes, through which screws can be inserted and connected to the boss 421. The first top feet 412 can be two or four, such as... Figure 3 and 6 As shown, there are four first top feet 412, which are symmetrically arranged in pairs on both sides of the mounting block 411, so that the abutment member 41 is X-shaped as a whole, and the two first top feet 412 are kept in an outwardly open state by the first elastic member 413 in the middle.

[0024] Specifically, the upper rail 1 has a hanging rail groove 10, with C-shaped grooves 143 on both sides of the hanging rail groove 10 and a mating groove 100 in the middle of the top of the hanging rail groove 10. The abutting member 41 is disposed in the mating groove 100, and the first top foot 412 abuts against both sides of the mating groove 100 through the first elastic member 413. An upper yarn guide rail 101 is disposed between the mating groove 100 and one of the C-shaped grooves 143. The boss 421 is located in the hanging rail groove 10, and the upper hanging wheel 43 is slidably disposed in the corresponding C-shaped groove 143. The two corresponding first top feet 412 are spread apart by the first elastic member 413 disposed in the middle, so that they remain abutting against the two side walls of the mating groove 100, providing friction for the handle 3.

[0025] Specifically, the lower rail 2 includes a base plate 21 and a lower yarn guide rail 102. A contact plate 212 is provided on the top of one side of the lower yarn guide rail 102. The bottom wheel assembly 5 includes a lower base 52 connected to the handle 3. A lower wheel 53 is provided on one side of the bottom of the lower base 52, and a passageway 520 is provided on the other side. The lower yarn guide rail 102 is located in the passageway 520. The upper yarn guide rail 101 and the lower yarn guide rail 102 are existing structures, mainly used to ensure the linear movement of the yarn mesh. The lower wheel 53 protrudes downward from the lower base 52 and slides on the base plate 21. The passageway 520 is mainly a clearance space provided to accommodate the lower yarn guide rail 102.

[0026] Specifically, the b-abutment member 51 is disposed within the passageway 520, and the b-abutment member 51 includes a connecting plate 511 and a second top foot 512. The second top foot 512 is disposed above the connecting plate 511, and a second elastic member 513 is disposed between the second top foot 512 and the connecting plate 511. The second top foot 512 abuts against the abutment plate 212 through the second elastic member 513. The b-abutment member 51 is fixedly connected to the bottom of the lower base 52 through the connecting plate 511, and one side of the connecting plate 511 extends into the passageway 520. One end of the second top foot 512 is connected to the end of the connecting plate 511, and the other end is bent upward. Under the action of the second elastic member 513, the second top foot 512 maintains an upward thrust, so that it abuts against the upper abutment plate 212, providing friction for the handle 3. It should be noted that both the first elastic member 413 and the second elastic member 513 can be springs.

[0027] 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.
