Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further specifically described below by way of embodiments and with reference to the accompanying drawings.
Example (b): a mechanical opening and closing system of a smoke opening switch door is shown in figures 1-7 and comprises a base 1 and a lifting head 2 arranged on the base 1 in a lifting mode, wherein the lifting driving mode of the lifting head 2 can be driven by an electric push rod. The relative upper portion of front side of lift head 2 is equipped with mouth of cigarette 3 along length direction, is provided with opening plate 4 on the mouth of cigarette 3, and opening plate 4 is close to the inboard at both ends and sets up on mouth of cigarette 3 through turning opening hinge 5 respectively to can overturn through the rotation of turning opening hinge 5, thereby open or close mouth of cigarette 3.
In the structure, one side bottom of base 1 is vertical to be equipped with fixed pipe 6, is equipped with movable pull rod 7 in the fixed pipe 6, and movable pull rod 7 can be followed fixed pipe 6 and is stretched out and drawn back from top to bottom to be located the bottom of fixed pipe 6 at movable pull rod 7 and be equipped with flange 8, flange 8's size is greater than the top mouth of pipe of fixed pipe 6, in order to avoid movable pull rod 7 to break away from fixed pipe 6.
A supporting seat 9 is fixedly arranged on the inner wall of the side surface of the lifting head 2, a hole for the movable pull rod 7 to pass through is arranged on the supporting seat 9, and the movable pull rod 7 is movably arranged in the hole of the supporting seat 9 in a penetrating way; after the movable pull rod 7 penetrates out of the supporting seat 9, a connecting rod seat 10 is movably sleeved on the opposite top of the movable pull rod 7, and a positioning piece is arranged at the top end of the movable pull rod 7, so that the connecting rod seat 10 is always positioned between the supporting seat 9 and the positioning piece; adjusting nut 11 is selected for use to the setting element in this embodiment, specifically, the top of activity pull rod 7 is equipped with the external screw thread that matches with adjusting nut 11, and adjusting nut 11 and the top threaded connection of activity pull rod 7 can adjust the position of setting element through rotating adjusting nut 11. In this embodiment, the movable pull rod 7 is sleeved with a power spring 12, and two ends of the power spring 12 respectively abut against the upper surface of the supporting seat 9 and the lower surface of the connecting rod seat 10.
In the structure, the connecting rod seat 10 is hinged with the connecting rod 13, and one end of the connecting rod 13 far away from the connecting rod seat 10 is hinged on the turning opening and closing hinge 5. Specifically, the turning open-close hinge 5 is a bent shape consisting of a straight edge and an arc edge, and one end of the arc edge is fixed with the open-close plate 4; one end of the straight edge is T-shaped, one side close to the opening plate 4 is hinged on a fixed seat at the inner side of the smoke outlet 3, and one side far away from the opening plate 4 is hinged with the connecting rod 13.
In the non-use state of the present embodiment, the distance from the limiting flange 8 at the bottom of the movable pull rod 7 to the top nozzle of the fixed pipe 6 should be slightly less than the maximum distance of the lifting head 2.
In the specific implementation of this embodiment, when the lifting head 2 is driven by an external force (in this embodiment, an electric push rod may be used) to lift, the movable pull rod 7 moves upward relative to the fixed pipe 6 until the limiting flange 8 is clamped at the pipe orifice of the fixed pipe 6, and then the lifting head 2 continues to move upward while the movable pull rod 7 remains stationary relative to the fixed pipe 6, that is, the movable pull rod 7 drives the connecting rod seat 10 to move downward relative to the lifting head 2 against the elastic force of the power spring 12, and the power spring 12 is compressed, so that the connecting rod 13 pulls the flip open-close hinge 5 to rotate, and the open-close plate 4 is opened, and when the lifting head 2 moves upward to the limit position, the open-close plate 4 is completely opened. The opening and closing angle of the opening and closing plate 4 can be adjusted by the adjusting nut 11, for example, when the opening and closing angle is not in place, the adjusting nut 11 can be adjusted downwards to enlarge the opening and closing angle.
When the lifting head part 2 descends under the driving of external force, the connecting rod seat 10 is loosened, and in a no-load and no-pull state, the connecting rod seat 10 is flicked by means of the elastic force of the power-assisted spring 12, so that the connecting rod seat 10 moves upwards relative to the lifting head part 2, the connecting rod 13 drives the turning opening and closing hinge 5 to rotate, and the opening and closing plate 4 is closed and closed tightly; the lifting head 2 then continues to move downwards and the movable tie rod 7 is reset.
The application model of the embodiment includes but is not limited to an integrated range or a side-draught range-down type range hood.
Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above-described embodiments, and many modifications are possible. All changes and modifications that may be made by the technical spirit of the present invention to the above embodiments by simple modification are considered to fall within the scope of the present invention.
