[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", "front end", "rear end", "two ends", "one end", "the other end", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0023] The utility model is a novel flat mesh screen door and window, which can be a screen door or a screen window. The difference between the screen window and the screen door lies in the different sizes. The screen door is taken as an example below.

[0024] like Figure 1 As shown, the screen door mainly includes an outer frame 1 and an inner flat net, which is arranged inside the outer frame 1. One end of the inner flat net is fixedly connected to one side of the inner side of the outer frame 1, and the other end of the inner flat net can slide inside the outer frame 1 to realize the expansion and folding of the mesh 2 in the inner flat net, thereby realizing the opening and closing of the door.

[0025] Specifically, the inner flat net is formed by hingedly connecting several mesh sheets 2, and adjacent mesh sheets 2 are hingedly connected using M-bars. The mesh sheets 2 have rotating cylinders at both ends, and the M-bars have circular grooves. The cylinders and the circular grooves cooperate to achieve the installation and cooperation of the mesh sheets 2 and the M-bars, thereby forming the entire inner flat net.

[0026] like Figure 1 As shown, one end of the inner flat net is fixed to the inner side surface of the outer frame 1, and a tension beam 5 is provided at the other end. In order to maintain the stability of the tension beam 5, a pulley assembly is provided at the upper end of the tension beam 5, and a supporting roller assembly is provided at the lower end of the tension beam 5. Specifically, the pulley assembly includes a pulley block 7 and four groups of support wheels 6 hingedly provided on the pulley block 7. These four groups of support wheels 6 adopt a two high and two low layout, that is, two groups of support wheels 6 are of the same height and different in height from the other two groups of support wheels 6 of the same height. The four groups of support wheels 6 slide in the slide. Two groups of support wheels 6 slide along the inner upper end surface of the slide, and the other two groups of support wheels 6 slide along the inner lower end surface of the slide. Preferably, the two groups of support wheels 6 on the outside are of low height, and the two groups of support wheels 6 on the inside are of high height. Specifically as Figure 2 shown.

[0027] like Figure 1 、 Figure 4 As shown, in the present invention, the M rod is divided into a sliding M rod 3 and a mobile M rod 4. Among them, the sliding M rod 3 slides along the slideway on the outer frame 1, and the mobile M rod 4 can move in the vertical direction relative to the slideway. The cooperation between the sliding M rod 3 and the mobile M rod 4 realizes the expansion and folding of the inner flat net. When folding, the mobile M rod 4 moves vertically relative to the slideway, away from the slideway, so that the two sliding M rods 3 can be close to each other.

[0028] In the present invention, a sliding wheel assembly is provided at the lower end of the sliding M rod 3, and the sliding M rod 3 is inserted and provided on the sliding wheel assembly using a rotating buckle rod 10. Figure 4 、 Figure 5 As shown, the sliding wheel assembly includes a sliding wheel seat 8 and a sliding wheel 9 hinged within the sliding wheel seat 8. During assembly, the sliding wheel assembly is installed on the lower slideway, and the sliding wheel 9 slides in engagement with the lower slideway. The sliding wheel assembly is connected to the sliding M rod 3 using a rotating buckle rod 10, which allows the sliding M rod 3 to move more smoothly.

[0029] An upper slider is connected to the upper end of the sliding M rod 3, and the upper slider 11 is installed on the upper slide, and the upper slider 11 is used to achieve slide movement coordination with the upper slide. In a specific implementation, preferably, the upper slider 11 has two sliding contact points with the upper slide, and the other two slide contact points are arc-shaped.

[0030] The utility model is provided with cards 12 at the upper and lower ends of the mesh 2. Figure 3 As shown, the card 12 has a slot 13 that fits into the end of the mesh 2. A retaining hole 14 is provided on the inner wall of the slot 13 of the card 12, corresponding to the retaining posts provided at the upper and lower ends of the mesh 2. During assembly, the card 12 is inserted into the ends of the mesh 2, precisely aligning the retaining holes 14 with the retaining posts to prevent the card 12 from falling. The hanging wheel assembly of the utility model has four sets of support wheels, each set at a different height. This ensures smooth and balanced left-right sliding. The utility model features smooth sliding in the sliding position, reducing friction and noise.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
