Technical Field

[0001] The utility model relates to the technical field of sliding windows, and specifically to a lower pulley assembly of a translation airtight window. Background Art

[0002] A sliding window is opened or closed by sliding two or more window sashes relative to each other. It has the characteristic of horizontal sliding, providing a spacious opening space and good ventilation effect. A translation door and window pulley is a pulley system specifically designed for sliding doors and windows, enabling the doors and windows to slide smoothly on the track for opening and closing. This pulley system is a key component of sliding doors and windows, determining the smoothness and service life of the opening and closing of the doors and windows.

[0003] In the prior art, for the utility model with the authorization publication number: CN209891924U and the name: A lower guide wheel assembly of a translation airtight door and window, the device proposed in this patent document can support the window sash through the combination of a pulley, a mounting bracket, and a support frame. Through the connection and cooperation of a guide post and a chute between the sliding piece and the support frame, combined with the installation of the sliding piece on the window sash frame and the sliding of the support frame, when an external force pushes or pulls the sliding piece, the sliding piece can enter the first groove or the second groove under the guidance of the guide post of the support frame, enabling the sliding piece to drive the window sash to translate in the direction from indoor to outdoor or from outdoor to indoor. In this way, the sliding piece will drive the window sash to translate, and the gap between the two window sashes will become smaller, ensuring the sealing performance of the doors and windows.

[0004] However, for the device proposed in the above patent document, although it can facilitate the improvement of the sealing between doors and windows and reduce the gap between doors and windows, the stability of the adjustment method relying only on the guide post and the chute is poor when adjusting the gap between the doors and windows, and it is prone to shaking and slight deviation during adjustment, resulting in the situation that the gap between the doors and windows is sometimes large and sometimes small, and then it is prone to the situation that the gap becomes larger and larger after long-term use.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention. Embodiment 1

[0023] As Figures 1 to 6 shown, this embodiment proposes a lower pulley assembly for a translation airtight window, which includes a mounting piece 1, a sliding frame 2, a fixing plate 3, and a mounting mechanism 4 that are sequentially stacked from bottom to top; a transverse movement assembly connected to the mounting piece 1 is provided under the sliding frame 2, and the transverse assembly is used for the transverse movement of the sliding frame 2.

[0024] In this embodiment, referring to Figures 1 through 6 , the setting of this transverse assembly can facilitate the transverse movement of the sliding frame 2 at the mounting piece 1, and can enable the sliding frame 2 to drive subsequent components to move synchronously during the transverse movement, and can also enable subsequent components to move longitudinally in the sliding frame 2 through the guiding effect during the transverse movement, so as to be able to adjust the distance between the doors and windows through longitudinal and transverse movements, greatly improving the sealing performance between the doors and windows.

[0025] Bolts 5 are provided outside the mounting piece 1, and the bolts 5 are used for the installation or disassembly of the mounting piece 1. By setting the bolts 5, it is possible to facilitate the installation of the mounting piece 1 to a predetermined position, thereby facilitating the installation of the doors and windows to the overall device, and through the setting of two bolts 5, it is possible to facilitate the installation and fixation of both sides of the mounting piece 1.

[0026] The transverse assembly includes a first sliding groove 6 opened on the bottom surface of the mounting piece 1, and a sliding rod 7 connected to the sliding frame 2 and slidably matched with the first sliding groove 6, and the transverse assembly is used for the transverse movement of the sliding frame 2; the transverse assembly also includes a second sliding groove 8 opened on the bottom surface of the sliding frame 2, and a connecting rod 9 connected to the mounting piece 1 and the fixing plate 3 and slidably matched with the second sliding groove 8, and the connecting rod 9 is used for the limiting and fixing of the fixing plate 3.

[0027] By providing the first sliding groove 6, it can cooperate with the sliding rod 7, enabling the sliding frame 2 to slide horizontally under the limiting effect of the mounting piece 1. Then, through the connecting rod 9, it is convenient to fix the fixing plate 3. The provision of the second sliding groove 8 can prevent the sliding frame 2 from being blocked by the connecting rod 9 during horizontal movement, thus facilitating the horizontal movement of the sliding frame 2.

[0028] The longitudinal component includes a second guiding groove 10 opened on the bottom surface of the fixing plate 3, and a second guiding rod 11 connected to the mounting mechanism 4 and slidably engaged with the second guiding groove 10. The longitudinal component is used for the longitudinal tilting movement of the mounting mechanism 4. By providing the second guiding groove 10, it can better enable the sliding frame 2 to drive the mounting mechanism 4 to move horizontally during horizontal movement. And during the horizontal movement of the mounting mechanism 4, it is limited and guided by the second guiding groove 10 and moves longitudinally within the sliding frame 2, thereby facilitating the adjustment of the position of the mounting mechanism 4, facilitating the first adjustment of the gap between doors and windows through the mounting mechanism 4, reducing the gap between doors and windows, improving the sealing performance, and significantly enhancing the transmission stability effect. Embodiment 2

[0029] As Figures 1 to 6 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes a longitudinal movement component provided in the fixing plate 3 and connected to the mounting mechanism 4. The longitudinal component is used for the longitudinal movement of the mounting mechanism 4; the mounting mechanism 4 is used for the rolling support and installation / dismantling of doors and windows.

[0030] In this embodiment, referring to Figures 1 through 6 , the provision of this mounting mechanism 4, by rotating the adjusting screw 403, the output end of the adjusting screw 403 is in threaded cooperation with the adjusting plate 405, so that the adjusting plate 405 drives the inner shell 404 to move horizontally within the outer shell 401, and the inner shell 404 is limited and guided by the first guiding groove 406 and the first guiding rod 407 to perform fine lifting and lowering. Furthermore, through the fine lifting and lowering of the pulley 408, it is convenient to install or dismantle the doors and windows.

[0031] The mounting mechanism 4 includes an outer shell 401 located within the sliding frame 2 and connected to the second guiding rod 11. An inner shell 404 is provided within the outer shell 401, and an adjusting plate 405 slidably engaged with a reserved groove within the inner shell 404; the mounting mechanism 4 further includes a clamping plate 402 connected to the outer shell 401 and in threaded cooperation with the adjusting plate 405, and an adjusting screw 403 fixed within the outer shell 401 and engaged with the clamping plate 402. The clamping plate 402 is used to drive the horizontal movement of the inner shell 404.

[0032] By setting the outer shell 401, the outer shell 401 can drive the components inside the installation mechanism 4 to move synchronously when moving horizontally and vertically at the same time. The setting of the adjusting screw 403 can facilitate adjusting the position of the adjusting plate 405 inside the inner shell 404 by rotating the adjusting screw 403. When the adjusting plate 405 moves horizontally at the adjusting screw 403, it can pull the inner shell 404 to move horizontally, so that the inner shell 404 and the subsequent guiding components can cooperate to adjust the gap between the doors and windows and the position of the doors and windows.

[0033] The installation mechanism 4 further includes a first guiding groove 406 opened inside the inner shell 404 and a first guiding rod 407 connected to the outer shell 401 and slidably engaged with the first guiding groove 406. Two rotatable pulleys 408 are provided inside the inner shell 404. The first guiding groove 406 and the first guiding rod 407 are used for the slight up and down movement of the pulleys 408 for the installation or disassembly of the doors and windows.

[0034] By setting the first guiding groove 406 and the first guiding rod 407, it is convenient to guide the inner shell 404 when it moves horizontally inside the outer shell 401, so that the inner shell 404 can be lifted and lowered under the guiding action of the first guiding groove 406 and the first guiding rod 407, thereby being able to adjust the height of the pulleys 408. Furthermore, it is convenient to place the doors and windows on the pulleys 408. After the doors and windows are placed, by adjusting the lifting of the pulleys 408, it is convenient to install the doors and windows stably, and avoid the doors and windows tilting and shaking, which affects the sealing performance between the doors and windows.

[0035] The mounting piece 1 is provided with a limiting rod 12 connected to the sliding frame 2 and slidably engaged with the outer shell 401. The limiting rod 12 is used for the longitudinal movement of the installation mechanism 4. By setting the limiting rod 12, it is convenient to limit the movement of the outer shell 401 during the horizontal and longitudinal processes, so that the outer shell 401 moves longitudinally inside the sliding frame 2, thereby being able to adjust the distance between the two doors and windows, and can also cooperate with the subsequent components to further adjust the distance and sealing performance between the doors and windows, and further improve the stability between the doors and windows.

[0036] The bottom surface of the sliding frame 2 is provided with a third sliding groove 13 slidably engaged with the second guiding rod 11. The third sliding groove 13 is used for the limiting movement of the second guiding rod 11. By setting the third sliding groove 13, it is better convenient for the installation mechanism 4 to move longitudinally inside the sliding frame 2, so that it is convenient to drive the installation mechanism 4 to move during the horizontal movement of the sliding frame 2, and the installation mechanism 4 can move longitudinally inside the sliding frame 2 through the mutual cooperation of the third sliding groove 13 and the second guiding rod 11 as the sliding frame 2 moves horizontally.

[0037] Working principle: When installing doors and windows, first install the mounting plate 1 to the designated position through the bolt 5. Then, by rotating the adjusting screw 403, the output end of the adjusting screw 403 is in threaded cooperation with the adjusting plate 405, so that the adjusting plate 405 drives the inner shell 404 to move horizontally within the outer shell 401. The inner shell 404 is limited and guided by the first guiding groove 406 and the first guiding rod 407 to perform fine lifting and lowering. Furthermore, through the fine lifting and lowering of the pulley 408, it is convenient to install or disassemble the doors and windows. After the doors and windows are installed, the position of the sliding frame 2 can be adjusted. The sliding frame 2 slides at the mounting plate 1 through the first sliding groove 6 and the sliding rod 7. And during the sliding process of the sliding frame 2, it drives the installation mechanism 4 to move synchronously. When the installation mechanism 4 moves along with the sliding frame 2, it is limited and guided by the second guiding groove 10 through the second guiding rod 11. Thus, the installation mechanism 4 can longitudinally shift within the sliding frame 2, and then can drive the doors and windows to move, making the two doors and windows in close contact, improving the sealing performance between the two doors and windows. Moreover, the transmission method is extremely stable, which can effectively prevent slight shaking after long-term use from affecting the sealing performance between the two doors and windows.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
