Technical Field
[0001] This utility model belongs to the field of PVC window and door technology, and specifically relates to a PVC window and door for use in windows and doors. Background Technology
[0002] A window sash is a sliding window, hanging window, along with its accessories or other frames, that closes off a window opening. With the continuous development of the construction and decoration industries, people have increasingly higher requirements for home decoration. Currently, window sashes are widely used due to their good sound insulation, heat insulation, and smooth sliding properties. In daily life, people usually exchange air in their homes by opening window sashes.
[0003] However, during the sliding window process, the force used by the operator varies. For example, the force used by the elderly, children, adult men and adult women is significantly different. If a strong person pushes and pulls the window, even if they think they are using very little force, the window will still collide with the window frame. Prolonged collisions can easily damage the window and reduce its service life. In severe cases, it can even cause the window to fall off. Therefore, there is an urgent need for a type of PVC window to solve the above problems. Utility Model Content
[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a plastic steel door and window for doors and windows, so as to solve the problem mentioned in the background art that the window sash and window frame collide, and the window body is easily damaged by long-term collision, which reduces its service life.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a PVC window / door, comprising a window frame body, a window / door body, and a buffer structure. Eight magnetic strips are fixedly connected to both ends of the window frame body. The front and rear ends of the window frame body are slidably connected to the window / door body. Four magnetic strips are fixedly connected to both ends of the window / door body. Two grooves are formed at the bottom of both ends of the window frame body. The buffer structure includes a hinge seat, and two hinge seats are provided. The two hinge seats are fixedly connected to the inner wall of the groove. The two hinge seats are rotatably connected to a rotating shaft. The rotating shaft is rotatably connected to one end of a rotating plate. The top of the rotating plate is rotatably connected to a rotating shaft. Rollers are rotatably connected to both ends of the rotating shaft.
[0006] Preferably, the first magnetic strip is the positive pole of the magnet, the second magnetic strip is the negative pole of the magnet, and the second magnetic strip corresponds to the position of the first magnetic strip.
[0007] Preferably, the first magnetic strip is embedded in the inner wall of the frame of the window frame body, and the second magnetic strip is embedded in the inner wall of the frame of the window frame body.
[0008] Preferably, a limiting plate is provided on the side of the hinge seat near the middle, and a limiting plate is provided on both the front and rear sides of the rotating plate.
[0009] Preferably, both ends of the rotating shaft are fitted with torsion springs, one end of the torsion spring abuts against the limiting plate 1, and the other end of the torsion spring abuts against the limiting plate 2.
[0010] Preferably, the roller is made of ceramic composite material and the surface of the roller is a smooth plane.
[0011] Preferably, the groove depth is equal to the thickness of the rotating plate and the roller.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This type of PVC window and door is equipped with a buffer structure. When the window is closed, pushing the window and door body causes it to slide within the guide rail of the window frame. When the frame of the window and door body contacts the rollers, friction causes the rollers to rotate. Simultaneously, the frame of the window and door body presses against the rollers, causing the rollers to drive the rotating plate downwards. The torsion spring is deformed under pressure, and its elasticity provides resistance, buffering the window and door body and preventing excessive force from being used during pushing and pulling, which could cause the window sash to collide with the window frame. Continuing to push the frame of the window and door body causes the bottom of the rotating plate to abut against the inner wall of the groove. At this point, the two rollers are located below the frame of the window and door body, thus no longer providing resistance. The buffer structure provides resistance when pushing the window and door body close to the window frame, preventing excessive force from being used during pushing and pulling, which could cause the window sash to collide with the window frame. Prolonged collisions can easily damage the window and reduce its service life.
[0014] 2. This type of PVC window and door is equipped with magnetic strip one and magnetic strip two. When the frame of the window and door body is attached to the frame of the window body, magnetic strip one attracts magnetic strip two, thereby making the edge of the window and door body fit more closely to the inner wall of the window frame body, improving the sealing performance. Magnetic strip one and magnetic strip two can prevent gaps between the edge of the window and door body and the inner wall of the window frame body when the window is closed, which would allow cold air to enter and reduce the heat preservation performance.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5 This utility model provides an embodiment of a PVC window / door, comprising a window frame body 1, a window / door body 2, and a buffer structure 3. Eight magnetic strips 11 are fixedly connected to both ends of the window frame body 1. The front and rear ends of the window frame body 1 are slidably connected to the window / door body 2. Four magnetic strips 21 are fixedly connected to both ends of the window / door body 2. Two grooves 12 are formed at the bottom of both ends of the window frame body 1. The buffer structure 3 includes hinge seats 31, with two hinge seats 31 provided. The two hinge seats 31 are fixedly connected to the inner wall of the grooves 12, and the two hinge seats 31 are rotatably connected to a pivot 33. The rotating shaft 33 is rotatably connected to one end of the rotating plate 34, and the top of the rotating plate 34 is rotatably connected to the rotating shaft 37. Both the front and rear ends of the rotating shaft 37 are rotatably connected to the rollers 38. The magnetic strips 11 and 21 can prevent gaps from forming between the edge of the window body 2 and the inner wall of the window frame body 1 when the window is not closed tightly, which would allow cold air to enter and reduce the heat preservation performance. The buffer structure 3 can provide resistance when the window body 2 is pushed to contact the window frame body 1, preventing excessive force from being used during the pushing and pulling process, which would cause the window sash to collide with the window frame. Long-term collisions can easily damage the window and reduce its service life.
[0023] Furthermore, magnetic strip 11 is the positive pole of the magnet, and magnetic strip 21 is the negative pole of the magnet. Magnetic strip 21 is positioned corresponding to magnetic strip 11. Magnetic strip 11 is embedded in the inner wall of the frame of the window frame body 1, and magnetic strip 21 is embedded in the inner wall of the frame of the window frame body 1. Magnetic strip 11 attracts magnetic strip 21, thereby making the edge of the door and window body 2 fit more closely to the inner wall of the window frame body 1, improving the sealing performance. Magnetic strip 11 and magnetic strip 21 can prevent gaps from appearing between the edge of the door and window body 2 and the inner wall of the window frame body 1 when the window is closed, which would allow cold air to enter and reduce the heat preservation performance.
[0024] Furthermore, a limiting plate 32 is provided on the side of the hinge seat 31 near the middle, and a limiting plate 35 is provided on both the front and rear sides of the rotating plate 34. The elastic force of the torsion spring 36 can be applied to the hinge seat 31 and the rotating plate 34 through the limiting plate 32 and the limiting plate 35.
[0025] Furthermore, torsion springs 36 are fitted at both ends of the rotating shaft 33. One end of the torsion spring 36 abuts against the limiting plate 32, and the other end of the torsion spring 36 abuts against the limiting plate 35. The roller 38 drives the rotating plate 34 to move downward. The torsion spring 36 is deformed by pressure. The elastic force of the torsion spring 36 provides resistance and buffers the door and window body 2.
[0026] Furthermore, the roller 38 is made of ceramic composite material, and the surface of the roller 38 is a smooth plane. When the frame of the door and window body 2 comes into contact with the roller 38, the roller 38 rotates due to friction. At the same time, the frame of the door and window body 2 squeezes the roller 38. The ceramic composite material prevents the roller 38 from damaging the frame of the door and window body 2.
[0027] Furthermore, the groove depth of the groove 12 is equal to the thickness of the rotating plate 34 and the roller 38. The frame of the door and window body 2 is pushed further, so that the bottom of the rotating plate 34 abuts against the inner wall of the groove 12. At this time, the two rollers 38 are located below the frame of the door and window body 2, so they no longer provide resistance.
[0028] Working principle: In use, when the window is closed, push the window / door body 2, causing it to slide within the guide rail of the window frame body 1. When the frame of the window / door body 2 contacts the roller 38, friction causes the roller 38 to rotate. Simultaneously, the frame of the window / door body 2 presses against the roller 38, causing the roller 38 to drive the rotating plate 34 downwards. The torsion spring 36 deforms under pressure, providing resistance through its elasticity, thus cushioning the window / door body 2 and preventing excessive force during pushing and pulling, which could cause the window sash to collide with the window frame. Continue pushing the frame of the window / door body 2 until the bottom of the rotating plate 34 abuts against the inner wall of the groove 12. At this point, the two rollers 38 are located below the frame of the window / door body 2. Instead of providing resistance, the buffer structure 3 provides resistance when pushing the window body 2 to almost contact the window frame body 1, preventing excessive force during the pushing and pulling process from causing the window sash to collide with the window frame. Prolonged collisions can easily damage the window and reduce its service life. When the frame of the window body 2 is attached to the frame of the window frame body 1, the magnetic strip 11 attracts the magnetic strip 21, making the edge of the window body 2 fit more closely to the inner wall of the window frame body 1, improving the sealing performance. The magnetic strip 11 and magnetic strip 21 can prevent gaps between the edge of the window body 2 and the inner wall of the window frame body 1 when the window is closed, which would allow cold air to enter and reduce the thermal insulation performance.
[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
