[0032] The present utility model discloses a side-pressing window, including a frame body, a sash body and a side-pressing window pulley structure, and the side-pressing window pulley structure is arranged between the frame body and the sash body.

[0033] See Figure 1-2 , the side-pressing window pulley structure includes a base 10, a transmission assembly 20, a sliding guide assembly 30, a first sliding auxiliary assembly 40 and a second sliding auxiliary assembly 50. The base 10 is fixedly connected to the sash body; the transmission assembly 20 is slidably connected to the base 10 along a first direction, and the first direction is the same as the length direction of the slide rail of the frame body; the sliding guide assembly 30 is in transmission connection with the transmission assembly 20 and slides in the slide rail of the frame body. The transmission assembly 20 is used to drive the sliding guide assembly 30 to slide along a second direction when the sash body opens and closes relative to the frame body, and the second direction is perpendicular to the first direction; the first sliding auxiliary assembly 40 is arranged between the base 10 and the transmission assembly 20 to reduce the friction force of the transmission assembly 20 sliding along the first direction; the second sliding auxiliary assembly 50 is arranged between the base 10 and the sliding guide assembly 30 to reduce the friction force of the sliding guide assembly 30 sliding along the second direction.

[0034] The side pressure window pulley structure of this solution is achieved by arranging the transmission assembly 20 and the sliding guide assembly 30 on the two sides of the base 10 respectively, and the transmission assembly 20 drives the sliding guide assembly 30 to slide in the second direction when sliding in the first direction. The first sliding auxiliary assembly 40 can reduce the sliding friction between the base 10 and the transmission assembly 20, and the second sliding auxiliary assembly 50 can reduce the sliding friction between the base 10 and the sliding guide assembly 30. When the fan body is locked to the frame, the transmission drive structure on the fan body drives the transmission assembly 20 to slide in the first direction, and the transmission assembly 20 drives the sliding guide assembly 30 to slide in the second direction, which can ensure that the fan body is stably pressed sideways onto the frame, and at the same time, the sliding guide assembly 30 can be stably connected to the slide rail of the frame, which increases the smoothness of the fan body locking operation.

[0035] See also Figure 3-6 The sliding guide assembly 30 includes a sliding plate 31, a guide wheel 32 and a driving connector 33. The base 10 is provided with a first slide groove 11 for sliding the sliding guide assembly 30. The sliding plate 31 slides in the first slide groove 11. The guide wheel 32 is connected to the sliding plate 31 and extends into the slide rail of the frame. One end of the driving connector 33 is connected to the sliding plate 31, and the other end of the driving connector 33 is connected to the transmission assembly 20.

[0036] Furthermore, a first guide hole 111 opened along the second direction is provided in the first slide groove 11 , one end of the driving connector 33 is connected to the sliding plate 31 , and the other end of the driving connector 33 passes through the first guide hole 111 and is connected to the transmission assembly 20 .

[0037] In this embodiment, the transmission assembly 20 includes a connecting rod 21 and a toggle member 22. The base 10 is provided with a second slide groove 12 for sliding of the transmission assembly 20. The connecting rod 21 is fixedly connected to the toggle member 22. The toggle member 22 is slidably connected to the second slide groove 12. The connecting rod 21 is connected to the external transmission drive structure. The toggle member 22 is provided with a second guide hole 221 inclined to the first direction. The driving connecting member 33 passes through the first guide hole 111 and is slidably connected to the second guide hole 221.

[0038] The connecting rod 21 is a transmission bar that is transmission-connected to the transmission box on the fan body. After the fan body is closed to the frame, the handle is rotated, and the transmission box drives the locking point lock seat to lock the fan body. The fan body is pressed onto the frame side, and at the same time, the transmission bar transmits the toggle member 22 along the first direction, and the driving connection member 33 in the second guide hole 221 of the toggle member 22 slides obliquely in the second guide hole 221. At the same time, due to the setting of the first guide hole 111, the driving connection member 33 can only slide along the second direction, that is, slide away from the locking direction of the fan body, to ensure that when the fan body is close to and locked in the frame, the relative position between the frame and the guide wheel 32 remains unchanged, thereby improving the locking stability of the fan body and the use stability of the guide wheel 32.

[0039] In this embodiment, the first sliding assistance component 40 includes a sliding shaft 41 and a bushing 42. The base 10 is provided with a sliding assistance groove 13 for accommodating the bushing 42. The sliding shaft 41 is fixed in the sliding assistance groove 13, and the bushing 42 is rotatably connected to the sliding shaft 41. The bushing 42 extends into the second sliding groove 12 and contacts the transmission component 20, and is used for self-rotating when the transmission component 20 slides to reduce the friction between the transmission component 20 and the second sliding groove 12.

[0040] Specifically, the sliding assistance groove 13 is arranged on the side of the first sliding groove 11. The arc-shaped outer side wall of the sliding shaft 41 extends into the inner side wall of the first sliding groove 11 and is tangent to the transmission component 20. The bushing 42 contacts the side wall of the toggling member 22. When the toggling member 22 slides in the first direction, it drives the bushing 42 to rotate, thereby minimizing the friction between the side wall of the toggling member 22 and the side wall of the second sliding groove 12.

[0041] In this embodiment, the second sliding assistance component 50 includes a first support plate 51, a second support plate 52 and a needle roller bearing 53. The needle roller bearing 53 is arranged between the first support plate 51 and the second support plate 52. The first support plate 51 is connected to the bottom of the first sliding groove 11 of the base 10, and the second support plate 52 is connected to the sliding plate 31 and is arranged opposite to the first support plate 51. It should be noted that the side-pressure window pulley structure of this solution is arranged at the bottom of the fan body. The first support plate 51 and the second support plate 52 are both rigid support plates, which can increase the load-bearing stability of the fan body, ensure that both the base 10 and the sliding plate 31 are in smooth contact with the needle roller bearing 53, and effectively reduce the sliding friction between the base 10 and the sliding plate 31.

[0042] In this embodiment, the side-pressure window pulley structure further includes a pulley component 60. The pulley component 60 includes a pulley mounting plate 61 and a pulley set 62.

The pulley set 62 includes a pulley member 621 and a pulley bearing 622. The pulley member 621 is sleeved on the pulley bearing 622, and the pulley bearing 622 is connected to the pulley mounting plate 61.

[0043] It can be understood that the side-pressure window pulley structure of this solution is arranged at the bottom of the fan body. The arc-shaped outer wall of the guide wheel 32 contacts the side wall of the slide rail of the frame body for guiding the fan body. The arc-shaped outer wall of the pulley set 62 slides on the steel rail of the frame body for load-bearing sliding.

[0044] In the present embodiment, the side pressure window pulley structure further includes an initial positioning assembly 70, which includes a positioning block 71 and a limiting block 72. The base 10 is provided with a positioning hole 14, and the toggle member 22 is provided with a limiting hole 222. The limiting block 72 is arranged in the positioning hole 14 and extends into the limiting hole 222 to limit the toggle member 22 during installation. The positioning hole 14 is inserted into the positioning hole 14 for positioning the positioning block 71. The initial positioning assembly 70 is used to position the toggle member 22 when assembling the side pressure window pulley structure, so as to facilitate the assembly of other parts. After the side pressure window pulley structure is assembled, the positioning block 71 and the limiting block 72 can be withdrawn without affecting the normal use of the toggle member 22.

[0045] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
