Technical Field

[0001] The utility model relates to the technical field of aluminum profile doors and windows, and in particular to an aluminum profile door and window guide rail which is easy to clean. Background Art

[0002] During use, the existing aluminum alloy door and window guide rails often have poor sliding due to the accumulation of dust, foreign matter, etc., which affects the opening and closing effects of the doors and windows, and even causes damage to the guide rails. A door and window with regional drainage disclosed in a Chinese patent with reference to patent application number CN202120159066.0 includes a lower frame and a lower guide rail, the lower guide rail is arranged above the lower frame, the lower guide rail is limitedly connected to the lower frame, the lower guide rail includes an outdoor lower guide rail and an indoor lower guide rail, the outdoor lower guide rail is provided with a plurality of first drainage holes on the side facing the outdoors, the indoor lower guide rail is provided with a plurality of first water leakage holes on the bottom surface facing the lower frame, the lower frame is provided with a plurality of second drainage holes on the side facing the outdoors, and the first water leakage holes are connected to the second drainage holes by air.

[0003] In the above structure, in order to improve the supporting effect of the guide rail, a circular protrusion or an umbrella-shaped protrusion is set at the top of the guide rail along the length direction, which can increase the contact area with the door and window guide wheel and thus improve the supporting strength. In addition, in order to make the movement of the doors and windows more stable, baffles need to be set at intervals on both sides of the guide rail to support the two sides of the doors and windows to prevent the doors and windows from leaving the guide rail. In this way, a plurality of spacing grooves are formed between the guide rails and between the guide rails and the baffles. When foreign objects fall into the spacing grooves, it is difficult to remove the foreign objects, which is inconvenient to clean. Even when removing the foreign objects, they will be interfered by the circular protrusions or umbrella-shaped protrusions, which brings inconvenience to cleaning. Usually, clamps or other tools are required to clean them, otherwise they are difficult to remove. If the foreign objects are not removed, the movement of the doors and windows will be affected and even the guide rails will be damaged. In addition, dirt is easily accumulated in the corners of the guide rail gaps, breeding bacteria and affecting family hygiene. Utility Model Content

[0022] Such as Figures 1 to 3As shown in the figure, this embodiment discloses an aluminum profile door and window guide rail that is easy to clean, including a guide rail body 1, a support guide rail 2 located in the middle of the guide rail body 1 for supporting the translation of the door / window, and an inner support portion 3 and an outer support portion 4 located on both sides of the guide rail body 1 for abutting against the indoor and outdoor door / window sills respectively. Specifically, the support guide rail 2 includes two inner guide rails 21 and outer guide rails 22 with the same structure and arranged in parallel at intervals. The tops of the inner and outer guide rails 21 and 22 are provided with a "person"-shaped support surface 200, and the two sides of the inner and outer guide rails 21 and 22 are also provided with a limiting surface 201 for preventing the door / window from detaching from the inner and outer guide rails 21 and 22. The guide wheels 5 at the bottom of the door / window are pressed against the "person"-shaped support surface 200, and baffles 6 extend downward on both sides of the guide wheels 5 at the bottom of the door / window, and the two baffles 6 on both sides respectively abut against the limiting surfaces 201 on both sides of the inner and outer guide rails 21 and 22. The "person"-shaped support surface 200 can not only improve the support strength of the guide rail but also provide a certain guiding function, and the limiting surfaces 201 provided on both sides of the guide rail can form a limit to prevent the door and window from detaching from the guide rail. In this way, there is no need to additionally set a limiting structure on both sides of the inner and outer guide rails 21 and 22, avoiding the formation of multiple spaced grooves on both sides of the guide rail, thereby increasing the width of the spaced groove between the inner and outer guide rails 21 and 22, facilitating the removal of foreign objects and the cleaning of dirt, and avoiding accumulation that affects hygiene.

[0023] In this embodiment, the top planes of the outer support portion 4 and the inner support portion 3 are both perpendicularly connected to the limiting surface 201. In order to avoid dirt accumulation at the vertical corners, a rounded corner structure 202 is provided at the vertical corners. Since there is usually a landing difference between the indoor and outdoor door / window sills, the top plane of the outer support portion 4 is lower than the top plane of the inner support portion 3, which can prevent outdoor water from flowing into the indoor.

[0024] In this embodiment, in order to avoid the top of the "person"-shaped support surface 200 being too sharp, the included angle of the support surface 200 is set between 145° - 155°, preferably 150°, and rounded corner structures 202 are provided at the tip of the support surface 200 and the connection portion between the support surface 200 and the limiting surface 201 for smooth transition, so as to avoid discomfort to the user caused by the edges and corners.

[0025] In this embodiment, a plurality of arch-shaped structure holes 10 are provided on the guide rail body 1, and the structure holes 10 extend through along the length direction of the guide rail body 1. By providing the arch-shaped structure holes 10, material waste can be reduced while ensuring the structural strength, thereby reducing the production cost.

[0026] Furthermore, since the door / window guide rail needs to be fixed at the door / window sill position by mud, and in order to improve the connection stability between the guide rail and the wall or the bottom surface, a plurality of sets of connecting feet 11 extending downward are provided at the bottom of the guide rail body 1. The contact area with the mud can be increased through the plurality of sets of connecting feet 11, and the connection effect can be improved.

[0027] Furthermore, in order to prevent the inner and outer guide rails 21 and 22 from being too high and tripping pedestrians, it is necessary to control the height of the tips of the inner and outer guide rails 21 and 22 from the top surface of the inner support portion 3 to be less than or equal to 1 / 4 of the height of the guide rail body 1, so that the possibility of being tripped can be reduced when pedestrians pass by.

[0028] The above content described in this specification is only an example of the present utility model. Those skilled in the technical field to which the present utility model belongs can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, as long as they do not deviate from the content of this specification of the present utility model or exceed the scope defined by this claims, they should all fall within the protection scope of the present utility model.
