Ball clamping sliding device and ball clamping sliding door window
The invention provides a ball clamping sliding device. The device comprises a bracket; the bracket comprises a pair of sidewalls, wherein the sidewalls are oppositely arranged; a sliding device body is arranged between the two sidewalls, comprising two oppositely-arranged magnets which are respectively connected with the sidewalls; inwards-concave spherical surfaces are arranged on the opposite surfaces of the two magnets; magnetic poles on the opposite surfaces of the magnets have the same magnetism; the inwards-concave spherical surfaces half encircle a metal ball; the centers of circles of the inwards-concave spherical surfaces are overlapped with the center of circle of the metal ball; an annular gap is formed between the two magnets and is respectively parallel to the two magnets. According to the ball clamping sliding device and a ball clamping sliding door window, the friction of the metal ball in rolling can be minimized during use, so that the frictional resistance can be reduced, and the style generated by opening and closing the door window can be reduced; the silence is ensured during use; the service life is prolonged; meanwhile, corresponding push supporting force can be generated during opening the door window, so that the force in opening and closing can be saved.
