Abstract
Description
Technical Field
[0001] The utility model belongs to the field of sliding doors and windows, and particularly relates to a roller row of a panoramic sliding door and window. Background Art
[0002] The roller row is an important component for realizing the reciprocating sliding of panoramic sliding doors and windows. The roller row is usually supported at the lower end of the door and window sash, and the roller row directly bears the door and window sash. When the door and window sash slides along the rollers of the roller row, the rollers roll under the load-bearing state. Since the lower end surface of the door and window sash is in direct contact with the roller, the contact surface between the two is large, the friction force increases, resulting in increased sliding resistance of the door and window sash, increased bearing capacity of the roller, accelerated wear of the lower end surface of the door and window sash, and even sliding noise. In particular, the lower end surface of the door and window sash is not constrained in the direction of the roller's rotation axis, which easily causes the door and window sash to swing back and forth. Utility Model Content
[0003] The utility model aims to provide a panoramic sliding door and window roller row, which reduces the wear of the door and window sashes during the sliding process along the rollers and prevents the door and window sashes from swinging.
[0004] The panoramic sliding door and window roller row includes a mounting frame, on which a plurality of rollers located in the same plane are mounted, each roller includes an axle and a roller, the roller is mounted on the axle through a bearing, the axle is mounted on the mounting frame, and the outer surface of the roller is provided with a groove for placing a gasket.
[0005] The groove is composed of two identical frustum surfaces, and a V-shaped block is provided at the bottom of the gasket, and the V-shaped block abuts against the two frustum surfaces.
[0006] There is one groove, and the groove is arranged along the center axis of the roller.
[0007] There are two grooves, which are symmetrically arranged along the center axis of the roller.
[0008] Guide rails are arranged on both sides of the top of the gasket, and the guide rails are arranged above the rollers.
[0009] A hook platform is provided on one side of the mounting frame, and a boss is provided on the other side of the mounting frame, and the boss is in contact with the elastic member.
[0010] The elastic member is a cylindrical plastic strip.
[0011] The beneficial effects of the utility model are as follows: a gasket is used as a sliding part to avoid direct contact between the door and window sashes and the roller, and the gasket slides along the groove guide to prevent the door and window sashes from swinging back and forth, thereby enhancing the stability of the door and window sashes during the sliding process; at the same time, the contact between the gasket and the groove reduces the contact surface, sliding friction and wear degree between the door and window sashes and the roller, thereby making the door and window sashes slide more smoothly, reducing the bearing capacity of the roller, preventing the roller from being deformed due to continuous bearing, and extending the service life of the door and window sashes and the roller.

[0015] Figure 4 It is a top view of the roller row of the second embodiment. DETAILED DESCRIPTION
[0016] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0017] like Figure 1-4 As shown, the panoramic sliding door and window is composed of a first door and window sash A and a second door and window sash B. The roller row is composed of four identical rollers 1 arranged in parallel at equal intervals. The rollers 4 of the four rollers are installed on the same plane, and the two ends of the four rollers 4 are installed on the mounting frame 2. The mounting frame 2 and the rollers 1 are both placed in the lower door and window sash cavity 6 of the lower door and window frame profile 5. The two ends of the axle 7 are installed on the rollers 4 through a pair of bearings 10. The two ends of the axle 7 extend from the corresponding bearings and are supported on the mounting frame 2.
[0018] The mounting frame 2 is placed at the bottom of the lower door and window sash cavity 6, and a hook platform 12 is provided on one side of the top of the mounting frame 2. The hook platform 12 hooks the rear side frame 13 of the lower door and window frame profile 5 from below, and a boss 15 is provided on the other side of the top of the mounting frame 2. The tip of the boss 15 abuts against the elastic member 16, which is preferably a cylindrical plastic strip, so that the elastic member can be filled and pressed into the profile groove of the front side frame 17 of the lower door and window frame profile 5. The elastic contact of the boss and the hook connection of the hook platform ensure the installation stability of the mounting frame under load-bearing state, and also make the roller shockproof and buffered under load-bearing and rotating state.
[0019] The outer surface of the roller 4 is provided with a groove 8, which is composed of two identical round table surfaces 11. The bottom of the gasket 3 is provided with a V-shaped block 9, which abuts against the two round table surfaces 11. Guide rails 14 are provided on both sides of the top of the gasket 3, and the guide rails 14 are arranged above the roller 4. The gasket 3 is correspondingly inserted into the guide groove 18 on the lower end surface of the first door and window sash A through the guide rails and is fixed to the lower end surface of the first door and window sash A by screws.
[0020] like Figure 1 , 2 As shown, in the first embodiment, there is one groove 8 , and the groove 8 is arranged along the central axis of the roller 4 .
[0021] like Figure 3 , 4 As shown, in the second embodiment, there are two grooves 8 , which are symmetrically arranged along the center axis of the roller 4 .
[0022] Using gaskets as sliding parts can avoid direct contact between door and window sashes and rollers, and the gaskets slide along the groove guide to prevent the door and window sashes from swinging back and forth, thereby enhancing the stability of the door and window sashes during the sliding process. At the same time, the contact between the gaskets and the grooves reduces the contact surface, sliding friction and wear between the door and window sashes and the rollers, making the door and window sashes slide more smoothly, reducing the bearing capacity of the rollers, preventing the rollers from deforming due to continuous load-bearing, and extending the service life of the door and window sashes and rollers.
