Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

It should be noted that the "transverse direction" herein refers to the length direction of the sliding plate 2 or the bottom plate 1, and the "longitudinal direction" herein refers to the width direction of the sliding plate 2 or the bottom plate 1.

Example 1

As shown in fig. 1~4, the utility model provides an adjustable mechanism, including bottom plate 1 and slide 2, bottom plate 1 is used for the installation to be fixed on the window frame, locating hole 11 has been seted up on bottom plate 1, slide 2 is arranged in bottom plate 1 top through the activity of adjusting part 3, and slide 2 has seted up through-hole 21, adjusting part 3 includes from the top down regulating part 31, eccentric wheel portion 32 and location axle part 33, eccentric wheel portion 32 is arranged in through-hole 21, and eccentric wheel portion 32 and through-hole 21 clearance fit, location axle part 33 passes through locating hole 11, specifically, the axis of regulating part 31 and eccentric wheel portion 32 is on the same straight line, the axis of eccentric wheel portion 32 and location axle part 33 is not on the same straight line, thereby drive adjusting part 3 through adjustment part 31 and rotate, locating hole axle part 11 restricts the radial movement of location axle part 33, make regulating part 31 and eccentric wheel portion 32 rotate with location 33 as the axis, eccentric wheel portion 32 and through-hole 21 clearance fit, and transmit the effort, thereby drive slide 2 horizontal migration, adjust the relative position between slide 2 and the bottom plate 1.

As a further improvement, as shown in fig. 2, the through hole 21 is a waist-shaped hole, and the long axis direction of the waist-shaped hole is perpendicular to the length direction of the sliding plate 2, so that there is a gap between the eccentric wheel portion 32 and the long axis direction of the waist-shaped hole, so that the sliding plate 2 does not swing along the longitudinal direction, but the sliding plate 2 only moves along the transverse direction, thereby not affecting the sealing between the window sash and the window frame in the longitudinal direction.

Preferably, as shown in fig. 3~4, the end surface of the eccentric wheel portion 32 is circular, so that the force transmission is more stable during the process of movably matching the eccentric wheel portion 32 with the through hole 21, and the sliding plate 2 and the window sash slide more stably along the bottom plate 1.
