Detailed Description

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

A telescopic ball comprises a set square component 1 and a connecting piece 5; the triangle assembly 1 comprises two triangles 11 and a rotating part 12; the centers of the two triangular plates are mutually connected through the rotating part 12 and rotate by taking the rotating part 12 as a circle center; the three vertexes of the upper triangular plate 11 of each group of triangular plate assemblies 1 are connected with the vertexes of the lower triangular plate 11 of the adjacent triangular plate assembly through the connecting pieces, and the three vertexes of the lower triangular plate 11 are connected with the upper triangular plates 11 of other triangular plate 1 assemblies connected with the lower triangular plate 11 through the connecting pieces 5; the multiple sets of the triangle assemblies 1 are connected to form a telescopic ball.

Every adjacent three summits of the last set square 11 of every set of set square subassembly 1 pass through the connecting piece 5 with the summits of the lower set square 11 of other set square subassemblies, the three summits of lower set square 11 pass through the connecting piece 5 with the last set square 11 of other set square 1 subassemblies that it is connected makes when two set square 11 relative rotations in arbitrary one group, the ball just can enlarge or shrink, as shown in fig. 1-3, the angle of rotation is different, will present different structures.

The telescopic ball structure can be applied to instruments which extend into a cardiovascular and help the expansion of blood vessels, the telescopic ball structure is arranged at the extending end, the area of the telescopic ball structure is changed by rotating any triangular plate component 1, the telescopic spherical area is controlled to be at the minimum value when the instrument extends into the cardiovascular and helps the cardiovascular and cerebrovascular expansion instrument, the instrument extends into a place needing to be expanded in the interior and can control to rotate any triangular plate component 1, so that the telescopic spherical area is enlarged and is supported in the blood vessels, and the function of expanding the blood vessels is achieved. The structure can change only when the arbitrary triangle plate component is manually rotated, so that the telescopic ball structure is not easy to deform after being stretched into the cardiovascular system, and the service life is prolonged.

The telescopic ball with the structure has the advantages of simple structure, simple manufacturing process and low cost, and the structure can be used in exhibitions, dance halls and buildings except for the main users.

The telescopic ball is made of steel or plastic, can be designed according to the application and the bearing capacity of the telescopic ball, has a simple structure, is simple and convenient to install, can be applied to multiple fields, such as medical machinery or building structures, and has a wide application range.

Preferably, the triangle 11 is an equilateral triangle.

The equilateral triangle has the advantages that the whole structure keeps consistent in the telescopic process, and the structure is more stable when the equilateral triangle is extended or contracted, so that the service life can be prolonged.

Preferably, each side of the triangle 11 is provided with a recess 100.

The weight of the triangle assembly 1 can be reduced by arranging the recess 100, so that the weight of the whole telescopic ball is reduced, labor is saved in the using process, and the cost is low. The application in the cardiovascular system is more convenient, not only plays a role in expanding the blood vessel, but also leads the blood to flow smoothly.

More preferably, the recess 100 is a semicircular recess.

When the triangular plate component rotates 30 degrees, a ball with a flower-shaped structure can be formed, the structure is attractive, the visual enjoyment of consumers is met, and the application of the structure in exhibition halls, buildings and dance halls is more.

Preferably, the connecting member 5 is located inside the telescopic ball structure.

Preferably, the telescopic ball is a deployable structure with a three-dimensional shape, which is composed of a plurality of sets of the triangle assemblies 1 and the connecting pieces 5.

In the past, triangular plates were used to form two-dimensional developable planar shapes, where triangular plate assemblies 1 were used to form three-dimensional developable structures, expanding the range of applications for developable structures.

Preferably, the connection between adjacent triangle assemblies 1 is a direct pivotal connection.

The direct pivot connection structure is more tense, reduces the area and is easier to apply to the cardiovascular system.

Preferably, at least one triangular plate 11 in the triangular plate component 1 is made of flexible materials; the triangular plate 11 made of flexible material is directly pivoted with other triangular plates 11 which are pivoted with the triangular plate 11 made of flexible material at the vertex pivoting points of the two pivoted triangular plates 11.

At least one triangular plate 11 in the triangular plate component 1 is made of flexible materials; the triangular plate 11 made of flexible material is flexibly connected with other triangular plates 11 made of flexible material at the top points of the two pivoted triangular plates 11.

The flexible material is made of flexible materials (such as nickel-titanium alloy, plastic and the like), and the flexible materials can be plastically or elastically deformed, so that the flexible materials can be directly connected with the connecting hinge which replaces a rigid material, and a hinge structure is replaced; the pivoting structure is simpler and more compact. The flexible link is a direct link of the same material parts, and its rotation is a deformation of its flexible material, without rotation between the hinge post and the hinge sleeve of the link in the form of a pin joint.

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.
