Detailed Description
The invention will be further described with reference to specific examples and figures.
As shown in fig. 1 to 4, the bracket fine adjustment structure of the sliding support for the door and window comprises a bottom plate 10, a link mechanism 30 and a bracket 20, wherein the link mechanism 30 is respectively hinged with the bottom plate 10 and the bracket 20, so that the bracket 20 and the bottom plate 10 can be relatively unfolded and folded. The link mechanism 30 and the hinge manner of the link mechanism 30 are already disclosed in the prior art, and thus are not described in detail. The improvement point of the invention is a bracket limiting plate 11 at the tail end of the bottom plate 10 and a clamping plate 21 at the tail end of the bracket 20.
The tail end of the bottom plate 10 is provided with a bracket limiting plate 11, and the bracket limiting plate 11 is formed by upwards bending and extending the tail end of the bottom plate 10 and is in an L-shaped structure with the bottom plate 10. The bracket limiting plate 11 includes a bracket limiting portion 111 and a window frame fixing portion 112 which are sequentially provided from bottom to top. The bracket arm limiting part 111 is provided with a limiting through hole 12 for the end part of the clamping plate 21 to pass through. The window frame fixing portion 112 is formed by bending and extending the top end of the bracket limiting portion 111 in the outward direction, that is, in the direction toward the window frame side, and is not on the same vertical plane as the bracket limiting portion 111. When the base plate 10 is mounted on the window frame, the window frame fixing portion 112 is attached to the side of the window frame, so that accurate positioning of the base plate 10 is facilitated, screw holes are formed in the window frame fixing portion 112, and the window frame fixing portion 112 is fixed to the side of the window frame by screws. Through the bending arrangement between the bracket limiting part 111 and the window frame fixing part 112, after the bottom plate 10 is installed on the window frame, a certain gap can be reserved between the bracket limiting part 111 and the side of the window frame, so that the end part of the clamping plate 21 can move in the limiting through hole 12.
The bottom surface of the tail of the bracket arm 20 is hinged with a clamping plate 21, the clamping plate 21 is arranged along the length direction of the bracket arm 20, and when the bracket arm 20 and the bottom plate 10 are folded relatively, one side end part of the clamping plate 21, facing the bracket arm limiting plate 11, penetrates into the limiting through hole 12. In this embodiment, the folding degree of the bracket arm 20 is affected by the clamping plate 21 and can be changed, and the folding degree of the bracket arm 20 is changed by adjusting the relative position of the end part of the clamping plate 21 and the limiting through hole 12, so that the folded position of the bracket arm 20 is finely adjusted, the window sash mounted on the bracket arm 20 can be completely closed, and the air tightness of the window sash is ensured.
The following fine tuning structure is adopted: the eccentric screw is penetrated on the bracket arm 20 and the clamping plate 21 to realize fine adjustment. Specifically, the eccentric screw 40 is an internal hexagonal eccentric screw, the eccentric screw 40 is screwed on one of the clamping plate 21 and the bracket arm 20, the eccentric hole 41 is arranged on the other, the eccentric screw 40 is provided with a gasket 42, the head of the eccentric screw 40 is positioned in the eccentric hole 41, the size of the eccentric hole 41 is larger than that of the head of the eccentric screw 40, and the side of the head of the eccentric screw 40 is attached to the side wall of the eccentric hole 41. When the eccentric screw 40 is turned, the head of the eccentric screw 40 can rotate along the side wall of the eccentric hole 41, and then the clamping plate 21 is driven to rotate around the hinge point 23, so that the position of the end part of the clamping plate 21 penetrating into the limiting through hole 12 changes, and when the end part of the clamping plate 21 is propped against the side of the limiting through hole 12, the folding degree of the bracket 20 changes due to the influence of the clamping plate 21 and the limiting through hole 12, namely, the folded position of the bracket 20 is adjusted.
In this embodiment, since the fine adjustment is performed by rotating the eccentric screw 40, the head of the eccentric screw 40 should be disposed at a position easy to operate, and if the head of the eccentric screw 40 is disposed on the bracket 20, since the bracket 20 is used to fix the window sash, the operation of the eccentric screw 40 is inconvenient after the window sash is fixed, and therefore, in this embodiment, the eccentric screw 40 is preferably fastened to the bracket 20, and the eccentric hole 41 is disposed on the clamping plate 21, so that the head of the eccentric screw 40 is disposed on the bottom surface of the clamping plate 21, thereby facilitating the operation of the eccentric screw 40. In addition, in order to facilitate the rotation of the clamping plate 21, a hinge point 23 for hinging the clamping plate 21 to the bracket arm 20 and a rotation point of the eccentric screw 40 are arranged along the length direction of the bracket arm 20.
In this embodiment, in order to enable the clamping plate 21 to smoothly rotate around the hinge point 23, the eccentric hole 41 is preferably elongated, the length of the eccentric hole 41 is set along the length direction of the clamping plate 21, the length of the eccentric hole 41 is greater than the diameter of the head of the eccentric screw 40, the width is equal to the diameter of the head of the eccentric screw 40, and the left and right sides of the eccentric hole 41 are semicircular in shape matched with the head of the eccentric screw 40.
In this embodiment, in order to ensure that the clamping plate 21 does not affect the movement of the bracket 20 in the process of opening and closing the bracket 20, and to facilitate the end of the clamping plate 21 to penetrate into the limiting through hole 12, the following structure is adopted: the clamping block 22 used for penetrating into the limiting through hole 12 is arranged at one side end part of the clamping plate 21, which faces the supporting arm limiting plate 11, the width of the clamping block 22 is smaller than that of the clamping plate 21, an arc-shaped section 211 is arranged at one side of the clamping plate 21, the clamping block 22 is transited to the clamping block 22 through the arc-shaped section 211, a straight-line section 212 is arranged at the other side of the clamping plate 21, and the tail end of the straight-line section 212 is bent and transited to the clamping block 22. The side of the clamping block 22, which is positioned at one side of the straight line section 212 of the clamping plate 21, is parallel to the straight line section 212 of the clamping plate 21 to form a straight line side 222; the side of the clamping block 22, which is positioned on one side of the arc section 211 of the clamping plate 21, is inclined to form an inclined side 221. The limiting through holes 12 are square through holes. During the fine adjustment process, the clamping block 22 penetrates into the limiting through hole 12. The arc-shaped section 211 of the clamping plate 21 and the inclined side 221 of the clamping block 22 are arranged, so that corners affecting the movement of the supporting arm 20 do not exist in the process of opening and closing the supporting arm 20 of the clamping plate 21, and the clamping block 22 can penetrate into the limiting through hole 12 along the inclined side 221; the square arrangement of the linear side 222 of the clamping block 22 and the limiting through hole 12 enables the clamping block 22 to stably prop against the side of the limiting through hole 12 so as to change the folding degree of the bracket arm 20.
In summary, the present invention has been described and illustrated in the specification, and has been made into practical samples and tested for multiple uses, and from the effect of the use test, it can be proved that the present invention can achieve its intended purpose, and the practical value is undoubted. The above embodiments are only for illustrating the present invention, and are not to be construed as limiting the invention in any way, and any person having ordinary skill in the art will realize that equivalent embodiments of partial changes and modifications can be made by using the disclosed technology without departing from the scope of the technical features of the present invention.
