DETAILED DESCRIPTION

[0029] The present application is further described in detail below in conjunction with the accompanying drawings.

[0030] The embodiment of the present application discloses a windproof, silent and sound-insulating door and window, which is used to reduce the probability of window dislocation during the process of opening or closing the door and window, and improve the safety factor.

[0031] refer to Figure 1 A windproof, silent and soundproof door and window comprises a window frame 11 and a sliding window form 12. In the present embodiment, the window frame 11 is a rectangular frame. The window frame 11 is composed of a bottom frame rod 111, a top frame rod 112 and two vertical frame rods 113. The two vertical frame rods 113 are vertically arranged, and the bottom frame rod 111 and the top frame rod 112 are horizontally arranged. The bottom frame rod 111, one of the vertical frame rods 113, the top frame rod 112 and the other vertical frame rod 113 are sequentially connected to form the window frame 11. The window frame 11 is sleeved on the sliding window form 12. Two sliding window forms 12 are provided. The two sliding window forms 12 are used to seal the window frame 11 together. The sliding window form 12 is slidably connected to the window frame 11. The sliding window form 12 slides back and forth in the horizontal direction to adjust the opening and closing effect of the window.

[0032] However, when the existing doors and windows are opened or closed, it is easy to cause the window to be misaligned, which poses certain safety hazards. Figure 1 , Figure 2Therefore, a limiting track 114 is provided on the window frame 11, and the limiting track 114 is used to limit the sliding trajectory of the sliding window form 12 relative to the window frame 11. The limiting track 114 has a simple structure and is easy to install. The limiting track 114 can limit the sliding trajectory between the sliding window form 12 and the window frame 11, thereby reducing the probability of window dislocation during the opening or closing of doors and windows and improving the safety factor. In this embodiment, the limiting track 114 is integrated on the bottom frame rod 111, and correspondingly, limiting slide bars 123 are provided at the bottom of the two sliding window forms 12, and a limiting slide groove 115 is provided on the limiting track 114 for the limiting slide bar 123 to be embedded.

The limiting slide bar 123 is arranged at the bottom of the sliding window frame 121. When the two sliding window bodies 12 seal the window frame 11 together, the two sliding window frames 121 are partially fitted. When the two sliding window bodies 12 overlap each other, the two sliding window frames 121 are completely fitted. Since the two sliding window bodies 12 seal the window frame 11 together, the sliding tracks of the two sliding window bodies 12 are parallel to each other and do not overlap, so the limiting slide groove 11 There are two limit slide grooves 115 and two limit slide bars 123 corresponding to each other. The two limit slide grooves 115 are parallel to each other and are arranged on the upper surface of the limit rail 114. The limit slide bars 123 at the bottom of the two sliding window bodies 12 are respectively embedded in the two limit slide grooves 115, which can not only limit the sliding track between the sliding window body 12 and the window frame 11, but also reduce the probability of window dislocation during the opening or closing of the door and window, thereby improving the safety factor; and the two sliding window bodies 12 can slide independently of each other.

[0034] In order to make the sliding window body 12 slide more smoothly relative to the window frame 11, balls 13 are arranged on both side walls of the limiting slide 123, and the balls 13 are rolled and embedded on the side walls of the limiting slide 123. In this embodiment, multiple balls 13 are arranged on both side walls of each limiting slide 123, and the multiple balls 13 are arranged at equal distances along the length direction of the limiting slide 123. The limiting track 114 is provided with a ball groove 11 for the balls 13 to slide and embed. 6. The ball groove 116 is opened on the groove wall of the limiting slide groove 115. The ball groove 116 is opened on the opposite side groove walls of the limiting slide groove 115. The length direction of the ball groove 116 is parallel to the length direction of the limiting slide groove 115. The ball 13 rolls in the ball groove 116 to reduce the friction between the limiting slide bar 123 and the limiting slide groove 115, further improving the smoothness of the sliding of the sliding window body 12 relative to the window frame 11, and improving the user experience of the operator.

[0035] refer to Figure 1 , Figure 3 and Figure 4Since the sliding window body 12 needs to slide open and close many times every day, it is easy to cause wear of the ball 13 and the wall of the ball groove 116, so the sliding window body 12 is provided with an oil dripping pipeline 14, the length direction of the oil dripping pipeline 14 is parallel to the length direction of the limit slide 123, the oil dripping pipeline 14 is connected to each ball 13, one end of the oil dripping pipeline 14 passes through the frame wall of the window frame 11 to form an oil dripping port 141, and the window frame 11 is provided with a sealing member for sealing the oil dripping port 141 In the present embodiment, the oil dripping pipeline 14 is opened along the length direction of the bottom frame rod 111, and one end of the oil dripping pipeline 14 passes through the bottom frame rod 111 to form an oil dripping port 141. The sealing member is a sealing stud 142, and the sealing stud 142 is filled and inserted in the oil dripping port 141. A sealing thread 143 is opened on the peripheral wall of the sealing stud 142, and an adapting thread 144 adapted to the sealing thread 143 is opened on the inner wall of the oil dripping port 141.

[0036] Since the oil dripping pipeline 14 is connected to each ball 13, a plurality of pipeline branches 145 are connected to the oil dripping pipeline 14 in the horizontal direction. The plurality of pipeline branches 145 are arranged at equal distances along the length direction of the bottom frame rod 111. The plurality of pipeline branches 145 correspond to the plurality of balls 13 one by one. The operator can drip lubricating oil into the oil dripping pipeline 14 from the oil dripping port 141. Since the oil dripping pipeline 14 is connected to the ball 13, and the ball 13 is rollingly connected to the limiting slide bar 123, the lubricating oil will spread to the peripheral wall of the ball 13 and the ball groove 116, thereby reducing the friction and loss between the peripheral wall of the ball 13 and the wall of the roller groove.

The length direction of the transmission rack 156 is perpendicular to the axial direction of the transmission gear 155. The transmission gear 155 and the transmission rack 156 are embedded in the sliding window frame 121. The window frame 11 is provided with a There is a locking slot 157 for the locking plug 151 to slide and embed, a locking positioning slot 158 ​​is provided at the bottom of the locking plug 151 near the locking slot 157, one end of the locking spring 153 is connected to the bottom of the locking positioning slot 158, and the other end of the locking spring 153 is connected to the locking protrusion 152, and the locking protrusion 152 is partially embedded in the locking positioning slot 158. A locking slot 159 is provided on the window frame 11, and the locking slot 159 is provided in the locking slot 157. On the groove wall, rotating the sliding handle 124 drives the transmission gear 155 to rotate and then drives the transmission rack 156 and the locking block 151 to slide horizontally, so that the locking block 151 is inserted into the locking slot 157. When the locking block 151 is inserted into the locking slot 157 and the locking protrusion 152 and the locking groove 159 are relative to each other, the spring force of the locking spring 153 embeds the locking protrusion 152 into the locking groove 159, completing the fixation between the window frame 11 and the sliding window body 12.

A drainage port 162 is provided on the window frame 11. The drainage port 162 runs through the bottom of one side wall of the drainage cavity 16. When encountering severe rainstorm weather, rainwater enters the drainage cavity 16 from the drainage hole 161 and is finally discharged through the drainage port 162, thereby reducing the probability of rainwater accumulating in the window frame 11.
