Roll in the horizontal direction P1 to drive the sliding effect of the door and window 2 .

It should be further explained that, in this embodiment, the connecting portion 12 is formed by extending outward from the outer surface of the base body 10 along the first horizontal direction P1. In practice, the connecting portion 12 can also be arranged at other positions, for example That is to say, the connecting part 12 can also be arranged on the top of the base body 10, which can also achieve the technical effect that the door and window roller device 1 can swing relative to the door and window 2 with the connecting piece 30 as the swing center.

Wherein, as shown in FIG. 3, the seat body 10 has a top 10a and a bottom opening 10b, the roller set 20 partially protrudes from the bottom opening 10b, and the connecting portion 12 is opposite to each other in the direction of the vertical reference line L1. It is disposed closer to the bottom opening 10b than the top 10a.

Please cooperate with Fig. 2 and Fig. 3, wherein the roller set 20 includes a roller seat 24, the side wall of the seat body 10 has a first guide groove 101, and the first guide groove 101 has a first open end 101a and a first Closed end 101b, the roller seat 24 has a first protrusion 241 extending outward from the surface of the roller seat 24, the first protrusion 241 can enter the first guide groove 101 from the first open end 101a and move To the first closed end 101b, the first guiding groove 101 is formed extending along an extension direction T, the extension direction T is not parallel to and not perpendicular to the vertical reference line L1, and the first open end 101a is in contact with the seat body 10 The bottom opening 10b communicates with each other; thereby, when the user intends to install the roller set 20 in the seat body 10, the first protrusion 241 of the roller seat 24 can be inserted into the first open end 101a. , and then move the first protruding member 241 to the first closed end 101b along the first guide groove 101, and then install the roller set 20 in the base body 10, through the first guide groove 101 obliquely The extended design can prevent the first protrusion 241 from detaching from the base.

In this embodiment, the first guide grooves 101 are arranged in pairs, and are respectively arranged as mirror images on opposite side walls of the base body 10, and the first protrusions 241 are also arranged in pairs corresponding to the first guide grooves 101, respectively. The mirrors are arranged on opposite sides of the roller base 24 .

To illustrate again, as shown in Figures 2 and 3, the side wall of the seat body 10 has a second guide groove 102, and the roller seat 24 has a second protrusion 242 extending outward from the surface of the roller seat 24, The second guide groove 102 has a second open end 102a and a second closed end 102b, the second open end 102a communicates with the bottom opening 10b of the seat body 10, and the second protruding member 242 can be opened from the second The open end 102a enters the second guide groove 102, wherein the second guide groove 102 is an arc-shaped guide groove, whereby the roller set 20 can use the first protruding member 241 as shown in FIG. 7 and FIG. When the roller set 20 pivots around the first protruding part 241, the second protruding part 242 moves between the second open end 102a and the second closed end 102b.

In this way, when the door and window roller device 1 is installed on the track 3, if the track has a height difference or is uneven, the roller set can swing up and down according to the height difference of the track as shown in Figure 7 and Figure 8 , so that when the user pulls the door and window 2, the door and window 2 can slide on the track 3 smoothly.

It should be further explained that, in this embodiment, the second guide grooves 102 are provided in pairs, and are respectively mirrored on opposite side walls of the base body 10 , and the second protrusions 242 are corresponding to the second guide grooves 102 They are arranged in pairs, and are respectively mirrored on opposite sides of the roller seat 24 .

Again, as shown in Figures 2 and 3, the side wall of the seat body 10 has a third guide groove 103, and the roller seat 24 has a third protrusion 243 extending outward from the surface of the roller seat 24. The third protruding part 243 can be an elastic piece, for example, when the user installs the roller set 20 in the seat body 10, the third protruding part 243 can be bent and deformed, so that the roller set 20 can pass through the seat In the accommodating space S of the body 10, when the third protrusion 243 is located at the third guide groove 103 corresponding to the seat body 10, the third protrusion 243 can pass through the third guide groove 103 and recover To the state before being deformed, thereby, the roller set 20 can be firmly accommodated inside the base body 10 and engaged with the base body 10 .

It is further explained that, in this embodiment, the third guide grooves 103 are arranged in pairs, and are respectively arranged in mirror directions on opposite side walls of the base body 10 , and the third protruding member 243 is corresponding to the third guide grooves 103 They are arranged in pairs, and are respectively mirrored on opposite sides of the roller seat 24 .

To sum up, the effect of this invention lies in that the seat body is connected to the connecting part in a pivotable manner relative to the connecting part through the connecting part, and the door and window roller device can be pivoted relative to the door and window, thereby, When the door and window roller device is installed on the track, if the track is bent or uneven due to poor construction quality or other reasons, the door and window roller device can move along with the track, so that the door and window can slide smoothly on the track 3 slide up.
