Technical Field

The invention relates to a turnover mechanism, in particular to a positioning hinge turnover mechanism.

Background

With the increasing price of houses, it is very important to fully utilize the limited space in the room, and some mechanisms with flip covers, such as storage boxes and storage beds, well solve the problem of small space in the room and are widely welcomed; most of the existing flip mechanisms are opened by assistance of springs, and the hidden danger that the upper cover is lifted too fast and bounces to hurt people easily occurs when the flip mechanisms are opened; and the problem of finger extrusion can occur during folding, and even the potential safety hazards of sudden falling of the upper cover and the like caused by the failure of the spring in an opening state can be caused.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides the positioning hinge turnover mechanism which is simple in structure and convenient to use.

In order to solve the technical problem, the invention is realized as follows:

a positioning hinge turnover mechanism is characterized in that: the device comprises an upper turnover plate, a lower turnover plate, a sliding connecting rod, a sliding groove, a positioning fastener, a clamping groove, a first positioning point and a second positioning point;

one end of the upper turnover plate is hinged with one end of the lower turnover plate, a clamping groove is vertically arranged in the middle of the lower turnover plate, and the lower end part of the clamping groove is a first positioning point; one side of the clamping groove is vertically provided with a connecting plate, the connecting plate is provided with a sliding groove and a second positioning point located at the upper end of the sliding groove, one end of the sliding connecting rod is hinged to the middle of the upper turnover plate, the other end of the sliding connecting rod is hinged to the positioning clamping piece, and the positioning clamping piece slides back and forth in the moving groove and is rotated and positioned through the first positioning point and the second positioning point.

The invention has the beneficial effects that: simple structure facilitates the use, avoids the potential safety hazard of bounce and tong when providing convenience, and the link mechanism of this application is opened and is more stable when drawing in, is suitable for multiple flip structure simultaneously.

Detailed Description

As shown in fig. 1: a positioning hinge turnover mechanism is characterized in that: the device comprises an upper turnover plate 1, a lower turnover plate 2, a sliding connecting rod 3, a sliding groove 4, a positioning clamping piece 5, a clamping groove 6, a first positioning point 7 and a second positioning point 8;

one end of the upper turnover plate is hinged with one end of the lower turnover plate, a clamping groove is vertically arranged in the middle of the lower turnover plate, and the lower end part of the clamping groove is a first positioning point; one side of the clamping groove is vertically provided with a connecting plate, the connecting plate is provided with a sliding groove and a second positioning point located at the upper end of the sliding groove, one end of the sliding connecting rod is hinged to the middle of the upper turnover plate, the other end of the sliding connecting rod is hinged to the positioning clamping piece, and the positioning clamping piece slides back and forth in the moving groove and is rotated and positioned through the first positioning point and the second positioning point.

FIG. 1 is an original state of an opening process;

FIG. 2 is a view showing that the turnover plate is lifted upwards to drive the connecting rod and the positioning fastener to vertically lift upwards in the opening process;

FIG. 3 shows the positioning clip being lifted upward to a maximum angle during the opening process, and driving the sliding slot during the opening process, and moving the positioning clip to a current position through a second positioning point, and temporarily fixing the angle;

FIG. 4 shows that during the opening process, the sliding groove is pressed downwards by the connecting rod, the positioning fastener approaches the first positioning point, the positioning fastener is clamped by the first positioning point by rotating the angle to the existing position due to the angle relationship, and the whole mechanism is fixed and supported by gravity and remains unchanged;

FIG. 5 shows the positioning clip being lifted upward to a maximum angle during the closing process, and the sliding slot being driven during the closing process, and the positioning clip being rotated to an existing position by a second positioning point, and the angle being temporarily fixed;

fig. 6 shows that in the closing process, the positioning clamping piece passes through the first positioning point in the descending process to enable the angle of the positioning clamping piece to be parallel to the sliding groove, and the positioning clamping piece cannot be clamped at the first positioning point in the pressing process.
