DETAILED DESCRIPTION

[0026] The following is a detailed description with reference to the drawings in conjunction with the embodiments, so as to provide a deeper interpretation of the technical features and advantages of the present invention.

[0027] As shown in FIGS. 1-5, a magnetic levitation push-pull side pressure door and window of the present invention includes a door leaf frame and a magnetic levitation mechanism accommodated in the door leaf frame. The door leaf frame includes door leaf 2, pulley 9 and slide rail 8. The pulley 9 is provided on the slide rail 8, the slide rail 8 is installed on the lower rail 6 of the door frame, a magnetic suspension mechanism is installed between the door leaf 2 and the slide rail 8, the magnetic suspension mechanism includes mutually exclusive first magnets 10 and Two magnets 11, the first magnet 10 The first connecting piece 3 is embedded in the door leaf 2, the second magnet 11 is fixed on the pulley 9 through the second connecting piece 5, the second connecting piece 5 is disposed in the clamping slot of the first connecting piece 3, and the clamping slot functions as The position-limiting function restricts the relative movement between the second connecting member 5 and the first connecting member 3 in the direction of the slide rail 8, and the second connecting member 5 and the first connecting member 3 are accommodated through the ball groove 4 and The ball gaps of the ball grooves 4 are connected together. The design of the gap size takes into account factors such as the repulsive force of the magnet and the overall gravity of the door leaf 2 so that the second connection member 5 and the first connection member 3 will not come into surface contact, thereby To reduce the friction between the second connection member 5 and the first connection member 3, the design of the ball is to ensure that the first magnet 10 and the second magnet 11 will not be directly contacted and damaged. At the same time, when an overload occurs, it can still Through the cooperation of the ball and the ball groove 4, the sliding function of the door and window is realized, and the friction force of the rolling motion of the ball is smaller than the sliding friction force.

[0028] In this regard, the first connection member 3 includes an upper cover plate and side plates 31 installed on both sides of the upper cover plate, and a cavity is provided between the side plate 31 and the second connection member 5, which is the second The side sliding movement between the connecting member 5 and the first connecting member 3 reserves a space. The upper cover plate is connected to the door leaf 2, and the side plate 31 is provided with holes matching the size of the ball groove 4. The distance between the side plate 31 and the second connecting member 5 is 0-10 mm, and the distance may be a single-sided distance to ensure that there is sufficient space for lateral movement of the doors and windows.

[0029] Further, the door leaf 2 and the door frame lower rail 6 are installed with a sealing strip 7 for sealing, the door and window side movement makes the sealing strip 7 separate or contact, in the separated state, the door and window movement does not move The sealing tape 7 will be worn, and the sealing effect is better under the contact state. The ball groove 4 is arranged symmetrically, and the glass 1 is installed in the door leaf 2. The first magnet 10 and the second magnet 11 may be permanent magnets or electromagnets. The materials of the second connecting member 5 and the first connecting member 3 are all zinc alloys, which are produced in large quantities by using zinc alloy molds, avoiding the use of steel (mainly considering stainless steel, but the price is high, and ordinary steel is prone to rust) At the same time, it is non-magnetic and has no magnetic interference.

[0030] The basic structure of the device of the present invention is that the upper cover of the first connection member 3 is installed with doors and windows, the second connection member 5 is installed on the pulley 9, and the interior of the first connection member 3 and the second connection member 5 is empty The cavity is equipped with mutually repelling magnets, the second connecting member 5 moves back and forth along the direction of the slide rail 8, the first connecting member 3 and the second connecting member 5 move relatively laterally (that is, move left and right), the left and right movement facilitates doors, windows and window frames It is sealed by a sealing strip 7 to enhance its sealing performance. The first connecting member 3 and the second connecting member 5 are mutually repulsive and there is a gap between them due to the magnetic force, so that the first connecting member 3 and the second connecting member 5 Relative lateral movement without friction.
