Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Figure 1, Figure 2 and Figure 3, the front view, left view and cross-sectional view of the portable insulating stool of the present invention are provided. The portable insulating stool shown is composed of an upper insulating board 1, a lower insulating board 2, and a The rod 3, the right telescopic rod 4 and the central telescopic rod 5 are composed, the upper insulating plate 1 and the lower insulating plate 2 are made of insulating materials, and the lower ends of the left telescopic rod 3 and the right telescopic rod 4 are hinged on the lower insulating plate 2 through the rotating shaft 10 On one side of the surface, the lower end of the central telescopic rod 5 is hinged to the other side of the upper surface of the lower insulating board 2 through a rotating shaft 10, and the upper ends of the left telescopic rod 3 and the right telescopic rod 4 are fixed on the lower surface of the upper insulating board 1. The insulating plate 1 can move up and down relative to the lower insulating plate 2 .

The shown left telescopic rod 3, right telescopic rod 4 and central telescopic rod 5 are all composed of an outer rod 7 and an inner rod 8, the inside of the outer rod 7 is an inner cavity 9, and the inner rod 8 is located in the inner cavity 9 of the outer rod 7 , The inner rod 8 can slide up and down along the inner cavity, so as to realize the up and down lifting of the upper insulation board 1 relative to the lower insulation board 2 . The lower ends of the outer rods 7 of the left telescopic rod 3, the right telescopic rod 4 and the central telescopic rod 5 are all hinged on the upper surface of the lower insulating plate 2, and the upper ends of the inner rods 8 of the left telescopic rod 3 and the right telescopic rod 4 are connected by connecting bolts. 18 is fixed on the lower surface of the upper insulation board 1. The outer rod 7 of the left telescopic rod 3 is connected with the outer rod 7 of the right telescopic rod 4 through the connecting rod 6, and the upper end of the inner rod 8 of the central telescopic rod 5 is hinged at the central position of the connecting rod 6.

As shown in Figure 4, the schematic diagram of the structure of the cooperation of the outer rod and the inner rod in the utility model is provided. Along its length direction, a bar-shaped groove 15 is opened, and the bar-shaped groove 15 communicates with the inner cavity 9 of the outer rod 7. A number of arc-shaped teeth 16 are arranged at intervals on the upper left side or upper right side of the bar-shaped groove 15, and the arc-shaped teeth 16 are fixed on the On the outer pole 7. Two spring seats 12 are fixed on the lower right or left side of the outer rod 7, and the inside of the spring seat 12 is a cylindrical cavity communicated with the inner chamber 9, and the inner cavity of the spring seat 12 is provided with a support spring 13 to support The outer end of the spring 13 is provided with a cylinder 14 , and under the action of the support spring 13 , the cylinder 14 will be forced to press the inner rod 8 .

The shown inner rod 8 is fixed with a limiting column 17, and the limiting column 17 protrudes from the bar-shaped groove 15. The limiting column 17 is used to cooperate with the arc-shaped tooth 16, and the arc-shaped tooth 16 faces the upper right or the upper left. When the inner rod 8 is subjected to an upward pulling force, the inner rod 8 will be forced to hold the support spring 13 due to the limiting and blocking effect of the arc-shaped tooth 16 on the limit post 17, and then the inner rod 8 will be pressed against the inner cavity 9. Move outwards to realize the rise of the upper insulating plate 1. After stopping the stretching of inner rod 8, under the effect of support spring 13, can force limit post 17 to be pressed to the side where arc-shaped tooth 16 is located, and the nearest arc-shaped tooth 16 of limit post 17 realizes its support and The position limit limits the movement of the inner rod 8 in the inner chamber 9, thereby making the position limit after the upper insulating plate 1 moves upward.

When the upper insulating plate 1 needs to be moved down, force the inner rod 8 to the side where the support spring 13 is located by hand, so that the limit column 17 can be moved to a position where the arc-shaped tooth 16 does not block it. The rod 8 can extend into the inner cavity 9 to realize the lowering adjustment of the upper insulating plate 1 .

After the inner rods 8 of the left telescopic rod 3 and the right telescopic rod 4 stretch out upwards, the upper insulating plate 1 is no longer located directly above the lower insulating plate 2. In order to adjust the position of the upper insulating plate 1, the adjustable The telescopic length of the inner rod 8 of the central telescopic rod 5 is to ensure that the upper insulating plate 1 is positioned directly above the lower insulating plate 2, and the central telescopic rod 5 has also realized the supporting effect on the left telescopic rod 3 and the right telescopic rod 4, so as to A stable support for the upper insulating board 1 is realized.

The folded schematic diagram of the portable insulating stool of the present invention shows that the lower insulating plate 2 is provided with a handle 11 on the side, and the upper surface of the upper insulating plate 1 is provided with evenly arranged anti-slip protrusions 19 to ensure that the staff can step on it stably On the upper insulation board 1. After the upper insulation board 1 descends to the position close to the lower insulation board 2, it can form the shape of a box as a whole, and the staff can carry the handle 11, which greatly facilitates carrying.
