Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
As shown in fig. 1 to 3, a two-dimensionally expandable and contractible plugging structure comprises a rotating seat 100, a fixed sliding chute 200 and a plugging plate; the plugging plate consists of four rotating units; the rotating unit comprises two triangular plates 310 with the same shape, hinge parts 312 are arranged at the vertex angles of two ends of the long edge of each triangular plate 310, and a central pivot part 311 is arranged at the other vertex angle far away from the long edge; the two triangular plates 310 are vertically stacked, and the central pivoting parts 311 of the two triangular plates 310 are overlapped and rotatably connected; two hinged parts 312 at two ends of each rotating unit are hinged with the hinged parts 312 at corresponding positions of the adjacent rotating units, so that the plugging plate is an expandable and contractible annular structure formed by sequentially hinging the four rotating units end to end; the rotating base 100 is rotatably connected with one of the central pivoting portions 311 on one side of the plugging plate, the sliding groove structure 210 of the fixed sliding groove 200 is slidably connected with one of the central pivoting portions 311 on the other side of the plugging plate, and the rotating base and the fixed sliding groove 200 are respectively located on two opposite sides of the plugging plate.
The blocking plate consists of four rotating units and eight triangular plates 310 with the same shape, and the two triangular plates 310 in each rotating unit form a structure which is two-layer up and down and can rotate relatively; when the two opposite central pivoting parts 311 of the blocking plate gradually approach, the blocking plate shrinks towards the center of the mouth-shaped structure, and finally a quadrilateral-like plate-shaped structure is formed and the mouth-shaped structure is completely blocked; when the two opposite central pivoting portions 311 are gradually far away from each other, the blocking plate gradually forms a ring shape and expands towards the periphery of the mouth-shaped structure, and finally the mouth-shaped structure is completely located at the hollow position in the middle of the ring-shaped structure, so that the blocking structure is completely blocked and opened.
Preferably, compared with the conventional structure, the blocking structure has the advantages that an operator only needs to slide one central pivoting part 311, and due to the special hinge mode of the blocking plate, the contraction or opening change degree of the blocking plate is twice of the sliding degree of the central pivoting part 311, so that the mouth-shaped structure can be opened or blocked more quickly.
When the adjacent rotating units are hinged, the hinge parts 312 arranged on the triangular plates 310 positioned on the same layer are hinged, so that the plugging plates form an annular structure with two layers of unfolding and contraction. Compared with other hinged modes, the plugging plate only forms an upper layer of annular structure and a lower layer of annular structure which can be expanded and contracted, so that the basic purposes of plugging and opening the plugging structure are achieved, the thickness of the plugging plate is reduced as much as possible, the overall structure of the plugging structure is more compact, the installation space is smaller, and the transportation is more convenient.
A handle 220 is disposed at a central pivot portion 311 of the blocking plate and the sliding groove structure 210. The plugging structure is convenient for an operator to more conveniently expand or contract, and is prevented from being damaged or scratched by clamping.
The other two central pivoting portions 311 of the blocking plate are slidably connected with the two guide grooves 400, respectively. The guide groove 400 is additionally arranged, so that four central pivoting parts 311 of the plugging plate are all provided with a guide sliding structure, and the plugging plate is more stable in the expanding and contracting processes.
The triangle 310 is an isosceles triangle 310. When the triangular plate 310 is set to be an isosceles triangular plate, the plugging plate is made to be a square after being completely contracted, the center pin joint parts 311 are respectively located at the middle positions of the four sides of the square, and in the actual use process, the center pin joint parts 311 are correspondingly installed near the middle positions of the four sides corresponding to the mouth-shaped structure, so that the center of the plugging plate is coincided with the center of the mouth-shaped structure, and the installation process of the plugging structure is more convenient. In practical application, most of the mouth-shaped structures are quadrilateral, and the plugging plates are arranged to be square, so that the plugging structure can plug more quadrilateral mouth-shaped structures with different shapes.
The upper ends of the two guide grooves 400 are inclined towards the fixed sliding groove 200, and form an included angle of 45 degrees with the direction of a connecting line between a rotating point of the rotating seat 100 and the geometric center of the plugging plate. Because the position of the central pivot part 311 fixed by rotating with the fixed seat is fixed, when the plugging plate performs expansion and contraction reciprocating motion, the two opposite central pivot parts 311 both form oblique lines on the wall surface of the mouth-shaped structure, the guide groove 400 is arranged according to the inclination angle of the oblique lines, and the guide groove 400 can also be fixed on the wall surface, so that the plugging plate can be stably hung on the wall surface of the mouth-shaped structure while the guide groove 400 plays a role in guiding.
The elastic skirt 500 is arranged at the edge of the triangle plate 310. When the plugging plate is completely contracted, certain gaps can exist in the splicing positions between the triangular plates 310, and the elastic skirt edge 500 can fill the gaps in the splicing positions between the triangular plates 310 on the same layer, so that the plugging effect of the plugging plate is better.
The elastic skirt edge arranged on the upper triangular plate 310 is protruded downwards, and the elastic skirt edge arranged on the lower triangular plate is protruded upwards. The bulge of the elastic skirt edge that upper and lower two-layer set square 310 was equipped with can seal the gap of two upper and lower layer plate structure concatenation department when upper and lower layer set square 310 splices, makes the shutoff effect of shutoff board further improves.
In practical use, the rotating base 100 and the fixed sliding chute 200 are respectively attached and fixed to the wall surfaces of two opposite sides of the mouth-shaped structure, and the extension line of the sliding direction of the sliding chute structure 210 passes through the rotating point of the fixed base, the geometric center of the plugging plate is as close to the center of the mouth-shaped structure as possible, and the guide groove 400 is installed and fixed on the wall surfaces of two opposite sides of the mouth-shaped structure, and has the above-mentioned inclination angle of 45 degrees. When the mouth-shaped structure is opened, an operator slides the handle 220 to enable the central pivoting part 311 at the handle 220 to slide to the farthest end of the chute structure 210 from the rotating seat 100, and the blocking structure is unfolded to the largest extent to form a largest ring shape, so that the mouth-shaped structure is positioned at a hollow-out position in the middle of the ring-shaped structure; on the contrary, when the mouth-shaped structure is plugged, only the handle 220 needs to be slid, so that the handle 220 slides to one end, close to the rotating seat 100, of the chute structure 210, at this time, the two triangular plates 310 of the rotating unit deviate from the rotation, so that the two triangular plates 310 between the two adjacent rotating units are spliced, and the four triangular plates 310 on the same layer of the plugging plate respectively form two baffle structures similar to quadrangles on one diagonal line of the mouth-shaped structure; the two layers of the triangular plates 310 are spliced in a staggered mode to form four quadrilateral baffles, and the complete baffle which is longer in area is spliced just in the cross section direction of the mouth-shaped structure and can completely block the mouth-shaped structure, so that the purpose of blocking the mouth-shaped structure by the blocking structure is achieved.
The technical principle of the present invention is described above in connection with specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive effort, which would fall within the scope of the present invention.
