Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, and more specifically to a novel sliding support for doors and windows. Background Art

[0002] Doors and windows are divided into enclosing components or partition components according to their location. They have different design requirements and must have functions such as thermal insulation, heat insulation, sound insulation, waterproofing, and fire prevention. New requirements require energy saving. In cold areas, the heat lost through gaps in doors and windows accounts for about 25% of the total heating heat consumption.

[0003] The connection between the slide rail and the connecting rod in the lower slide support of doors and windows mostly produces dry friction. Long-term dry friction not only makes the connection prone to friction damage, but also increases the friction resistance of the connection, making it inconvenient to move the connecting rod. At the same time, the left and right sides of the slide rail are mostly deformed to prevent the connecting rod from sliding off the upper end of the slide rail. The deformed slide rail is not easy to separate from the connecting rod, which makes it inconvenient to replace parts and carry out maintenance work. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model aims to provide a new type of lower sliding support for doors and windows, by arranging a concave ball hole at the upper end of the slide rail, the inside of the concave ball hole is connected to the ball rolling, and strip grooves are respectively arranged at the front and rear ends of the lower end of the slider, so as to facilitate the limiting of the ball, and facilitate the limiting rolling of the ball through the concave ball hole and the strip groove, thereby reducing the dry friction at the connection between the slide rail and the slider, thereby reducing the friction resistance at the connection, and facilitating the sliding of the slider inside the slide rail. At the same time, by arranging limit grooves on the left and right sides of the slide rail, the limit grooves are slidably engaged with the limit blocks, and the upper ends of the limit blocks are respectively fixedly connected to the left and right stop blocks, thereby facilitating the limiting and blocking of the left and right sides of the interior of the slide rail, and conveniently blocking the left and right sides of the upper end of the slide rail, and also conveniently removing them, thereby facilitating the separation and connection of the slide rail and the slider.

[0005] To solve the above problems, the utility model adopts the following technical solutions.

At the same time, limiting grooves are respectively arranged on the left and right sides of the slide rail, and the limiting grooves are slidably engaged with the limiting blocks, and the upper ends of the limiting blocks are respectively fixedly connected to the left and right stop blocks, thereby facilitating the limiting blocking of the left and right sides of the inner part of the slide rail, and conveniently blocking the left and right sides of the upper end of the slide rail, and also conveniently removing, thereby facilitating the separation and connection of the slide rail and the slider.

The arrangement of the ball bearings reduces the friction resistance at the connection between the slide rail and the slider, making it easier for the slider to slide on the upper end of the slide rail.
