[0018] Figure 2 This is a disassembled diagram of the base in this embodiment. DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model, but the utility model is not limited to the following embodiments.

[0020] like Figure 1 to Figure 2 As shown, the present embodiment discloses a side-pressure door and window base, comprising a guide wheel seat 1 slidably fitted on the door and window guide rail and a connecting seat 2 connected to the bottom of the door and window, the connecting seat 2 slidably fits on the top of the guide wheel seat 1 laterally, the direction in which the connecting seat 2 slides laterally is perpendicular to the moving direction of the door and window, the top of the connecting seat 2 is also provided with a driving assembly for driving the connecting seat 2 to slide laterally, the driving assembly comprises a driving block 3 slidably fitted on the top of the connecting seat 2 along the moving direction of the door and window, a driving rod 5 engaged with the driving block 3, and a driving rod 5 passing downward through the connecting seat 2 and connected to the guide wheel seat 1 The top of the guide column 4 is matched with the driving block 3 for guidance. Specifically, the driving block 3 is provided with a guide groove / guide hole 30. The extension direction of the guide groove / guide hole 30 is at an angle with the sliding direction of the driving block 3. The top of the guide column 4 is matched with the guide groove / guide hole 30 for sliding. The driving rod 5 is connected with the door and window handle. When the door and window handle is turned, the driving block 3 is driven to slide on the connecting seat 2 by the driving rod 5. The driving block 3 drives the connecting seat 2 to move laterally relative to the guide wheel seat 1 by matching with the guide column 4 through the guide groove / guide hole 30. In the above structure, the guiding and lateral sliding functions of the doors and windows can be realized by only five components: the guide wheel seat 1, the connecting seat 2, the guide column 4, the driving block 3 and the driving rod 5. It has few parts, a simple structure, and perfect functions. It is not only easy to maintain, but also has a low production cost and higher practicality.

[0021] In this embodiment, a slide groove 20 for sliding the driving block 3 is provided at the top of the connecting seat 2 along the moving direction of the door and window, and an active hole 21 is provided at the middle position of the bottom of the slide groove 20 to prevent the connecting seat 2 from interfering with the guide column 4 when sliding laterally. The active hole 21 passes through the connecting seat 2 up and down. When the connecting seat 2 moves laterally, the guide column 4 moves in the active hole 21. By restricting the driving block 3 to slide in the slide groove 20, the driving block 3 drives the guide column 4 to move in the active hole 21, thereby driving the connecting seat 2 to slide laterally. This method can reduce the sliding resistance of the driving block 3 in the slide groove 20, avoid rapid wear of the driving block 3, and increase the service life.

[0022] Furthermore, in order to facilitate the installation of the drive block 3 while preventing the drive block 3 from escaping from the slide slot 20, the width of the drive block 3 is less than or equal to the width of the slide slot 20, and pressure plates 22 for pressing on the drive block 3 are provided on both sides of the slide slot 20 along the extension direction of the slide slot 20. The pressure plates 22 on both sides are fixed to the top of the groove walls on both sides of the slide slot 20 by screws. Specifically, after the pressure plates 22 are fixed, their edges extend horizontally into the inside of the slide slot 20 and protrude from the groove walls, and the extended ends of the pressure plates 22 press against the edges on both sides of the drive block 3, and pressure structures 31 for the pressure plates 22 to press are provided on both sides of the drive block 3. However, it should be noted that there is a gap between the top surface of the pressure structure 31 and the bottom surface of the protruding end of the pressure plate 22, so that the drive block 3 can move more smoothly along the slide slot 20.

[0023] In this embodiment, since the driving rod 5 and the driving block 3 are only subjected to force along the moving direction of the door and window, the connection structure can be simpler. In order to facilitate the cooperation between the driving rod 5 and the driving block, arc-shaped grooves 32 are provided at both ends of the driving block 3, and the bottom of the driving rod 5 extends downward to have a card column 51 for snapping into the arc-shaped grooves 32 at both ends. The outer contour of the card column 51 is adapted to the card column 51, and in order to prevent the card column 51 from easily detaching from the arc-shaped groove 32, the shortest distance between the arc-shaped grooves 32 at both ends is greater than the shortest distance between the two groups of card columns 51, so that the arc-shaped grooves 32 at both ends can be interference fit with the card column 51, thereby improving the fastening effect.

[0024] In this embodiment, in order to improve the guiding effect of the guide column 4 between the guide groove / guide hole 30 and improve the smoothness, a ring sleeve 41 is rotatably engaged at the top of the guide column 4, and the bottom end of the ring sleeve 41 is against the top of the guide wheel seat 1 to form a support. The outer surface and the inner surface of the ring sleeve 41 are both smoothly arranged, and the ring sleeve 41 is slidably engaged with the guide groove / guide hole 30.

[0025] In this embodiment, in order to realize relative lateral sliding between the connecting seat 2 and the guide wheel seat 1, a connecting groove 21 is provided at the bottom of the connecting seat 2 and passes through the connecting seat 2 laterally. The connecting groove 21 is provided with two groups and is respectively arranged at positions close to the ends at the front and rear ends of the connecting seat 2. The top of the guide wheel seat 1 corresponds to the two groups of connecting grooves 21 and is provided with a connecting part 11 that cooperates with the connecting groove 21. The connecting part 11 is slidably matched with the connecting groove 21.

[0026] Furthermore, both ends of the bottom of the connection seat 2 extend inwardly to form limiting portions 22 for preventing the connection portion 11 from escaping from the connection groove 21 . The limiting portions 22 abut against the bottom of the connection portion 11 to vertically limit the connection portion 11 in the connection groove 21 .

[0027] In this embodiment, the bottom of the guide column 4 passes through the guide wheel seat 1, the guide column 4 and the guide wheel seat 1 are rotatably matched, and the bottom end of the guide column 4 is connected to the guide wheel 42 to form a limit.

[0028] The above contents described in this specification are merely examples of the present invention. Technicians in the technical field to which the present invention belongs can make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the contents of the present invention specification or exceed the scope defined by the claims, they should all fall within the protection scope of the present invention.
