[0029] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0030] Referring to Figure 1 In the present embodiment, the roller support assembly includes a roller and a roller support. The roller support includes a bottom plate 1 fixed on the profiled track and a vertical plate 2 perpendicular to the bottom plate 1, and a chamfer is provided at the connection of the bottom plate 1 and the vertical plate 2. In order to ensure the connection strength of the bottom plate 1 and the vertical plate 2, it is preferred to be rounded to prevent stress concentration at the connection of the bottom plate 1 and the vertical plate 2. The included angle between the bottom plate 1 and the vertical plate 2 is preferably 90 degrees, and can also be slightly larger or smaller than 90 degrees. The vertical plate 2 is provided with a connecting shaft 3 for connecting the roller. The included angle between the axial direction of the connecting shaft 3 and the vertical plate 2 is also preferably 90 degrees, and can also be slightly larger or smaller than 90 degrees. In the preferred embodiment, the bottom plate 1 is parallel to the axial direction of the connecting shaft 3.

[0031] Referring to Figure 2aAs shown, the connecting shaft 3 can be divided into a first sub-shaft and a second sub-shaft; for the convenience of description in combination with the drawings, they can also be referred to as a left half connecting shaft 30 and a right half connecting shaft 31 from the perspective of an observer, however, it should be understood that "half" here does not necessarily mean "half" but can mean any suitable proportion. The left half connecting shaft 30 and the right half connecting shaft 31 are integrally formed, however, the diameter of the left half connecting shaft 30 is greater than the diameter of the right half connecting shaft 31. The diameter of the left half connecting shaft 30 is also greater than the inner diameter of the roller, thereby playing an axial limiting role on the roller, which can prevent the roller body from rubbing against the vertical plate when the roller rotates. The connecting shaft 3 can movably connect the roller, in order to facilitate the specific connection relationship between the connecting shaft 3 and the roller, a plane rectangular coordinate system is established, and the axial direction of the connecting shaft 3 is set as the direction of the X coordinate axis. As is apparent, the roller has a rotational degree of freedom around the X coordinate axis, but the movement degree of freedom in the direction of the X coordinate axis is limited. As shown, in addition to the diameter of the left half part playing a limiting role on the roller, the connecting shaft 3 is also provided with a barb (see below for details), which is also used for axially positioning the roller bearing to prevent the roller from moving axially.

[0032] In this embodiment, in order to ensure the connection strength of the bottom plate 1 and the vertical plate 2 and prevent stress concentration, the connection between the bottom plate 1 and the vertical plate 2 is preferably uniformly provided with a reinforcing rib 5, and the number of the reinforcing rib 5 is determined by the width of the bottom plate 1. The reinforcing rib 5 is preferably provided on the side of the connection, of course, it can also be provided in the middle of the connection.

[0033] In addition, the bottom plate 1 is machined with a boss 13 at the lower end of each end, and the position of the boss 13 corresponds to the position of the groove of the profile track, so as to realize the clamping of the bottom plate 1 and the profile track. The width of the boss is slightly smaller than the width of the rectangular groove of the profile track, for example, 0.1-0.2mm smaller, which facilitates the smooth placement of the boss in the rectangular groove. Referring to Figure 2b , the height of the boss 13 is set such that the lower surface is higher than the upper surface of the buckle 12. The height of the boss is preferably 1-2mm.

[0034] Referring to Figure 2b and Figure 3As shown, in the embodiment, the bottom plate 1 is provided with a post 11 protruding beyond the upper and lower sides of the bottom plate. The post 11 includes a first sub-post and a second sub-post, which can also be referred to as a left post 111 and a right post 112 from the perspective of an observer. The left post 111 and the right post 112 are symmetrically designed. The post (including the left post 111 and the right post 112) is semicircular in shape as a whole, and the cross-sectional shape is arc-shaped and ring-shaped. Therefore, the left post 111 and the right post 112 can be combined to form a hollow cylindrical three-dimensional structure. After the left post 111 and the right post 112 are inserted into the rectangular slot in the middle of the profile rail and rotated by 90 degrees, the gap between the left post 111 and the right post 112 is inwardly retracted. The bottom of the left post 111 and the right post 112 is respectively provided with a buckle 12, so as to facilitate the clamping of the bottom plate 1 on the profile rail, thereby realizing the fixation of the roller support assembly and the profile rail. The width of the buckle 12 is less than the width of the opening of the rectangular slot of the profile rail, so that the buckle 12 can be placed in the rectangular slot of the profile rail. The length of the buckle 12 is slightly greater than the width of the bottom of the rectangular slot of the profile rail, so that the end of the buckle 12 is tightly fitted with the side of the rectangular slot. In order to increase the contact area of the buckle 12 and the two sides of the profile rail, the buckle 12 is preferably a rectangular buckle. The hollow cylindrical three-dimensional structure, i.e., the structure with a gap between the left post 111 and the right post 112, is conducive to the locking of the buckle 12 and the profile rail.

[0035] Referring to Figure 3 As shown, in the embodiment, the bottom plate 1 is provided with an opening near the left post 111 and the right post 112. The cross-sectional shape of the opening is preferably also approximately semicircular. The opening reduces the weight of the connecting bracket and saves manufacturing costs. In order to further reduce the weight of the connecting bracket and save manufacturing costs, a plurality of slots are also provided on the bottom plate 1.

[0036] Referring to Figure 3 and Figure 4As shown, the parts of the connecting shaft 3 are continuously described. In this embodiment, in order to facilitate the sleeve connection of the roller 4 to the right half connecting shaft 31 and to ensure the smooth rotation of the roller 4 along the right half connecting shaft 31, the right half connecting shaft 31 comprises a first side branch 311, a second side branch 312 and a middle branch 313, and a plurality of barbs 314 are arranged on the first side branch 311 and the second side branch 312. The barbs 314 can be retractable to facilitate the locking of the roller 4. Preferably, the barbs 314 are non-retractable barbs located at one end of the first side branch 311 and the second side branch 312 for facilitating the manufacturing process. The plurality of barbs 314 are uniformly and symmetrically arranged circumferentially on the first side branch 311 and the second side branch 312. The first side branch 311, the second side branch 312 and the middle branch 313 are provided with notches. The middle branch 313 can be fixed or retracted after being extruded by the first side branch 311 and the second side branch 312 for facilitating the sleeve connection to the right half connecting shaft 31. In this embodiment, the middle branch 313 is fixed for facilitating the manufacturing process. In order to more conveniently sleeve the roller 4 to the right half connecting shaft 31, the middle branch 313 can also be divided into two parts, which are designed similarly to the first side branch 311 and the second side branch 312. For example, if the first side branch is regarded as the left side branch and the second side branch is regarded as the right side branch, the middle branch 313 can be divided into an upper middle branch and a lower middle branch, and the upper middle branch and the lower middle branch also have notches. In this embodiment, the middle branch 313 is of an integrated type for facilitating the manufacturing process.

[0037] It should be understood that in other embodiments, the connecting shaft 3 can be divided into a plurality of branches, and the branches are provided with notches for sleeve connection of the roller. In this case, the notches extend to the vertical plate, rather than only extending to the left half connecting shaft.

[0038] Referring to Figure 5 and Figure 6 As shown, when the roller bracket assembly is installed on the profile rail, the bottom surface of the bottom plate 1 is attached to the upper surface of the profile rail, the two ends of the boss 13 are attached to the openings of the rectangular groove of the profile rail, the buckle 12 is embedded in the rectangular groove of the profile rail, and the end of the buckle 12 is tightly attached to the side surface of the rectangular groove of the profile rail.

[0039] Referring to Figure 7As shown, the mounting method of the roller bracket assembly of the present application on the profiled track comprises the following steps: step S1, the roller 4 is sleeved on the connecting shaft 3, when the roller 4 is pressed in, the barb 314 axially locks the roller bearing, so that the roller 4 is sleeved on the roller bracket; step S2, the angle of the roller bracket is adjusted, so that the direction of the buckle 12 is consistent with the extension direction of the profiled track; step S3, the buckle 12 is aligned with the opening of the rectangular groove of the profiled track; step S4, the roller bracket is moved, so that the buckle 12 is placed inside the rectangular groove of the profiled track, and the boss 13 is placed outside the rectangular groove of the profiled track; step S5, the roller bracket is rotated, so that the buckle 12 is clamped inside the rectangular groove of the profiled track; step S6, the roller bracket is moved again, so that the boss 13 is clamped in the opening of the rectangular groove of the profiled track, and the roller bracket is mounted on the profiled track.

[0040] The detailed mounting process of the roller bracket assembly on the profiled track is as follows:

[0041] Firstly, after the roller 4 is sleeved on the connecting shaft 3, the direction of the buckle 12 of the roller bracket is adjusted, so that it is consistent with the extension direction of the profiled track; secondly, after the buckle 12 is aligned with the opening of the rectangular groove of the profiled track, the roller bracket is moved downward, so that the buckle 12 is placed inside the rectangular groove of the profiled track. Then, the roller bracket is rotated by 90 degrees, so that the direction of the buckle 12 is perpendicular to the extension direction of the profiled track. The depth of the boss 13 is set, so that the lower surface of the boss 13 is still higher than the upper surface of the buckle 12, so that the boss 13 will not block the rotation path of the buckle 12.

[0042] When the roller bracket is rotated, the left stand 111 and the right stand 112 are deformed, the gap between the left stand 111 and the right stand 112 is contracted, when the roller bracket is rotated by 90 degrees, one end of the buckle 12 abuts against the side surface of the rectangular groove of the profiled track, so that the buckle 12 is locked with the profiled track, thereby mounting the roller bracket on the profiled track. Finally, the roller bracket is further moved downward, so that the boss 13 is also clamped in the opening of the rectangular groove of the profiled track, which also plays a role in preventing the further rotation of the roller bracket.

[0043] The above is only a preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement, deformation and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
