[0011] Compared with the prior art, the utility model has the beneficial effects that the hardware for doors and windows not only protects the door and window components, facilitates the resetting of the mounting plate, but also increases the service life of the limit roller;
[0012] (1) By providing the mounting groove, the limiting roller, the extension block, the fixing rod, the reserved groove and the connecting rod, the return spring can make the mounting plate have a certain angle through its own elasticity. When the bottom end of the door and window slides inside the slide rail, the limiting roller inside the mounting plate can limit the door and window to slow down the door and window, thereby buffering the door and window to prevent the door and window from sliding too fast and causing the window body to collide with the other side of the slide rail, thus affecting the service life of the door and window.

Since the limited telescopic rod is movably hinged between the mounting blocks and the limit slider slides inside the limit slide groove, the limited telescopic rod can conveniently limit the mounting plate when it rebounds, thereby preventing the mounting plate from deflecting when it rebounds. When the mounting plate rebounds, the limit slider will slide inside the limit slide groove;
[0014] (3) By providing the ball bearing, the rolling groove and the connecting rod, when the door or window moves at one end of the mounting plate, the limit roller will rotate on the outside of the connecting rod through the rotating groove, and when the limit roller rotates, the ball bearing will roll inside the rolling groove, thereby reducing the friction between the connecting rod and the limit roller. Reducing the friction can not only facilitate the rotation of the limit roller on the outside of the connecting rod, but also increase the service life of the connecting rod and the limit roller.

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Example 1: Please refer to Figure 1-4 A hardware for doors and windows, comprising a slide rail 1, a mounting groove 2 is provided at one end of the slide rail 1, a mounting plate 3 is provided inside the mounting groove 2, an extension block 8 is fixedly connected to one side of the mounting plate 3, a reserved groove 10 is provided inside the extension block 8, a fixing rod 9 is fixedly connected to one side of the mounting groove 2, a connecting rod 11 is fixedly connected to the inside of the mounting plate 3, and a limited sliding roller 4 is provided outside the connecting rod 11;
[0022] There are multiple groups of limit rollers 4, and the limit rollers 4 are arranged at equal intervals inside the mounting plate 3;
[0023] Specifically, Figure 1 and Figure 3 As shown, the return spring 14 will make the mounting plate 3 have a certain angle through its own elasticity. When the bottom end of the door and window slides inside the slide rail 1, the limiting sliding roller 4 inside the mounting plate 3 will limit the door and window to slow down the door and window, thereby buffering the door and window to prevent the door and window from sliding too fast and causing the window body to collide with the other side of the slide rail 1, affecting the service life of the door and window. It can also reduce the noise generated when the door and window are closed. The reserved groove 10 can facilitate the mounting plate 3 to be hinged on the other side of the fixing rod 9.
[0024] Embodiment 2: A limiting slide groove 16 is provided at the bottom and the top of both ends of the mounting plate 3, a return spring 14 is fixedly connected to the other end of the mounting plate 3, the return spring 14 is fixedly connected between the mounting plate 3 and the slide rail 1, a limiting telescopic rod 12 is provided at the bottom and the top of the return spring 14, and mounting blocks 13 are provided at both ends of the limiting telescopic rod 12, one end of the mounting block 13 is fixedly connected to a limiting slider 15, the limiting slider 15 slides inside the limiting slide groove 16, and the limiting telescopic rod 12 is movably hinged between the mounting blocks 13;
[0025] Specifically, Figure 1 and Figure 2 As shown, the return spring 14 can make the mounting plate 3 rebound to its original position through its own elasticity. Since the limiting telescopic rod 12 is movably hinged between the mounting blocks 13 and the limiting slider 15 slides inside the limiting slide groove 16, the limiting telescopic rod 12 can conveniently limit the mounting plate 3 when it rebounds, thereby preventing the mounting plate 3 from deviating when it rebounds. When the mounting plate 3 rebounds, the limiting slider 15 will slide inside the limiting slide groove 16.
[0026] Embodiment 3: A rotation groove 5 is provided inside the limiting sliding roller 4, and the limiting sliding roller 4 rotates outside the connecting rod 11 through the rotation groove 5. Rolling grooves 7 are provided on both sides of the rotating groove 5. Balls 6 are provided inside the rolling groove 7. The balls 6 roll inside the rolling groove 7. The balls 6 are provided on both sides of the connecting rod 11.
[0027] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, when the door or window moves at one end of the mounting plate 3, the limiting roller 4 will rotate outside the connecting rod 11 through the rotation groove 5, and when the limiting roller 4 rotates, the ball 6 will roll inside the rolling groove 7, thereby reducing the friction between the connecting rod 11 and the limiting roller 4. Reducing the friction can not only facilitate the rotation of the limiting roller 4 outside the connecting rod 11, but also increase the service life of the connecting rod 11 and the limiting roller 4.
[0028] Working principle: When the utility model is in use, when the bottom end of the door and window slides inside the slide rail 1, the limit roller 4 inside the mounting plate 3 will limit the door and window to slow down the door and window, so as to buffer the door and window to prevent the door and window from sliding too fast and causing the window body to collide with the other side of the slide rail 1, which affects the service life of the door and window, and can also reduce the noise generated when the door and window are closed. When the door and window move at one end of the mounting plate 3, the limit roller 4 will rotate outside the connecting rod 11 through the rotation groove 5. When the limit roller 4 rotates, the ball 6 will roll inside the rolling groove 7, so as to reduce Reduce the friction between the connecting rod 11 and the limiting sliding roller 4. Reducing friction can not only facilitate the limiting sliding roller 4 to rotate outside the connecting rod 11, but also the return spring 14 will make the mounting plate 3 a certain angle again through its own elasticity after the door and window are pushed back, which is convenient for the next buffering of the door and window. Since the limiting telescopic rod 12 is movably hinged between the mounting blocks 13 and the limiting slider 15 slides inside the limiting slide groove 16, the limiting telescopic rod 12 can facilitate the limiting of the mounting plate 3 when it rebounds, and the limiting slider 15 will slide inside the limiting slide groove 16 when the mounting plate 3 rebounds.
