The emergence of side pressure door and window just solves the short board of sliding door and window in water and air tightness, and the side pressure door and window seals by lateral extrusion of rubber strip, which has the performance of side hung door and window and the advantage of large light transmittance of sliding door and window.

[0003] However, in the existing market side pressure sliding door and window system, there is a gap between the upper guide wheel body and the frame guide rail. When the fan body is opened, if a reciprocating force perpendicular to the fan body is applied, due to the gap between the wheel body and the guide rail, the fan body will swing, which will produce noise and affect the use effect of the door and window. Therefore, some side pressure sliding door and window designs an elastic guide wheel, which uses the elastic force of torsional spring to act on two guide wheels, so that the two guide wheels are always deflected to the two sides and tightly contact the guide rail, so as to fill the gap between the guide rails and avoid the swing of the fan body. However, since the two guide wheels are always deflected to the two sides under the action of the elastic force of the torsional spring, when the guide wheels are installed into the frame guide rail, collision may occur, which may damage the guide wheels. It is necessary to use additional operation to collect the guide wheels inward to be able to be installed, which makes the installation operation complicated. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0024] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application. Moreover, the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0025] Figure 1 and Figure 2 respectively show the overall structure schematic diagram and the exploded structure schematic diagram of the roller device 100 of the side pressure sliding door and window according to an embodiment of the present application. Referring to Figure 1 and Figure 2 shown, the roller device 100 mainly comprises a base 10, a sliding block 20, a roller assembly 30 and an elastic member 40. The base 10 is provided with a lateral through dovetail groove 11, and the sliding block 20 is provided with dovetail blocks 21 at both ends thereof and is slidably installed in the dovetail groove 11, so that the sliding block 20 can slide laterally in the dovetail groove 11 relative to the base 10. The roller assembly 30 further comprises a supporting bottom plate 31, a first roller 32 and a second roller 33. The supporting bottom plate 31 is provided with a mounting hole 311 in the middle portion thereof, and the sliding block 20 is provided with a riveting column 22 in the middle portion thereof. The supporting bottom plate 31 is riveted to the riveting column 22 through the mounting hole 311, so as to be installed on the sliding block 20 in a manner that the supporting bottom plate 31 can rotate relative to the sliding block 20 about the riveting column 22. The first roller 32 and the second roller 33 are respectively provided on both ends of the supporting bottom plate 31. Specifically, the supporting bottom plate 31 is respectively provided with a first mounting column 312 and a second mounting column 313 at both ends thereof, and the first roller 32 and the second roller 33 are rotatably installed on the first mounting column 312 and the second mounting column 313, for example, by riveting. Thus, the first roller 32 and the second roller 33 can rotate together with the supporting bottom plate 31 relative to the sliding block 20. The elastic member 40 is abutted between the sliding block 20 and the supporting bottom plate 31, so that the first roller 32 and the second roller 33 always have a tendency to deflect laterally relative to the sliding block 20. Specifically as Figure 2As shown, the elastic member 40 includes a first V-shaped spring 40a and a second V-shaped spring 40b, both of which have the same structure, have a first edge 41 and a second edge 42, and form a limiting column 43 at the end of the second edge 42. The first edges 41 of the first V-shaped spring 40a and the second V-shaped spring 40b are respectively abutted in the clamping grooves 314 respectively formed on the different sides of the two ends of the supporting bottom plate 31, the second edges 42 of the first V-shaped spring 40a and the second V-shaped spring 40b are respectively abutted with the supporting blocks 24 respectively arranged on the two ends of the sliding block 20, and the limiting columns 43 at the end of the second edge 42 are inserted into the limiting holes 23 respectively arranged on the sliding block 20, so as to prevent the first V-shaped spring 40a and the second V-shaped spring 40b from being pressed out. In this way, the elastic force of the first V-shaped spring 40a and the second V-shaped spring 40b acts on the different sides of the two ends of the supporting bottom plate 31, so that the first guide wheel 32 and the second guide wheel 33 at the two ends of the supporting bottom plate 31 have a tendency to deflect to the two sides relative to the sliding block 20.

[0026] According to the above-mentioned embodiment of the guide wheel device 100 of the present application, the base 10 is fixed on the door / window leaf, and the door / window handle is operated. The force can be transmitted through the hardware components of the door / window to make the sliding block 20 slide laterally relative to the base 10. This specific implementation is already a prior art, and will not be described in detail in the present application. The first guide wheel 32 and the second guide wheel 33 of the guide wheel assembly 30 are arranged in the guide rail 200 (see Figure 4 and Figure 6 ) of the door / window frame, so that the door / window leaf can move horizontally along the extension direction of the guide rail 200. Since the first guide wheel 32 and the second guide wheel 33 always have a tendency to deflect to the two sides under the elastic force of the first V-shaped spring 40a and the second V-shaped spring 40b, in order to facilitate the installation of the first guide wheel 32 and the second guide wheel 33 in the guide rail 200, the present application also designs a limiting block 34 and a limiting protrusion 13 arranged in cooperation with each other between at least one of the two ends of the supporting bottom plate 31 and the base 10, for limiting the tendency of the first guide wheel 32 and the second guide wheel 33 to deflect to the two sides, and restraining the first guide wheel 32 and the second guide wheel 33 in the retracted state in the initial state. During the lateral sliding of the sliding block 20 relative to the base 10, the limiting block 34 can break the limiting protrusion 13 by relative movement, thereby releasing the limitation of the first guide wheel 32 and the second guide wheel 33.

[0027] Specifically referring to Figure 2 in combination with Figure 3 As shown, the end of the supporting bottom plate 31 close to the first guide wheel 32 is provided with a limiting block 34, and the limiting block 34 extends downward from the end of the supporting bottom plate 31 to the base 10. The corresponding position on the base 10 is provided with a limiting protrusion 13 for abutting against the limiting block 34. In order to facilitate the force to be broken, the root of the side of the limiting protrusion 13 abutting against the limiting block 34 can be provided with a notch 131, so that the root of the limiting protrusion 13 is more fragile. When the guide wheel device 100 is in the initial state, referring toFigure 3 As shown, the slider 20 is located at the right side of the dovetail groove 11 of the base 10, and the right side edge of the dovetail groove 11 is further provided with one or more stop edges 12 abutting against the slider 20 to limit the slider 20. At this time, the limiting block 34 on the support bottom plate 31 also abuts against the limiting protrusion 13 on the base 10, thereby limiting the first guide wheel 32 and the second guide wheel 33 from deflecting to the lateral sides, and the first guide wheel 32 and the second guide wheel 33 are basically retracted in the middle. When the guide wheel device 100 is loaded into the guide rail 200, see Figure 4 As shown, since the first guide wheel 32 and the second guide wheel 33 are limited to be in the middle retracted state, the first guide wheel 32 and the second guide wheel 33 have a gap with the first side wall 201 and the second side wall 202 of the guide rail 200, and can be conveniently loaded into the guide rail 200 along the extension direction of the guide rail, and the problem of the guide wheel colliding with the guide rail does not occur. After the door / window leaf is installed, see Figure 5 As shown, the operation handle can transmit the force through the door / window hardware to drive the slider 20 to slide to the left relative to the base 10. In the process of the slider 20 sliding to the left, the limiting block 34 slides to the left together with the slider 20, thereby applying a force to the limiting protrusion 13 to break the limiting protrusion 13, and the limitation on the first guide wheel 32 and the second guide wheel 33 is removed. The first guide wheel 32 and the second guide wheel 33 are deflected to the two sides under the elastic force of the first V-shaped spring 40a and the second V-shaped spring 40b, respectively, and abut against the first side wall 201 and the second side wall 202 of the guide rail 200, thereby automatically compensating for the guide rail gap and avoiding the door / window leaf from swinging, see Figure 6 As shown.

[0028] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
