DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Reference Figure 1-Figure 8 A multi-angle limit connection device for splicing building blocks, comprising at least one hemisphere 1, on which at least one connecting sleeve 3 is installed, the number of connecting sleeves 3 can be selected according to the work of splicing building blocks, and a hemisphere 1 with a large number of connecting sleeves 3 can be selected, or a hemisphere 1 with a small number of connecting sleeves 3 can be selected, the connecting sleeve 3 is internally threaded with a building block part 6, and the hemispheres 1 are connected to each other through a limit assembly, such as Figure 6 and Figure 8 As shown, the limit assembly includes a connecting ring 18 installed on one of the hemispheres 1, a mounting hole 15 is provided on the side wall of the hemisphere 1, the bottom end of the connecting ring 18 is connected to an annular accommodating plate 16 through a rotating member 23 made of flexible material, an air cavity 22 that is interconnected is provided between the annular accommodating plate 16 and the connecting ring 18, the upper end of the connecting ring 18 is connected to a bellows 19, the end of the bellows 19 that is away from the connecting ring 18 is connected to a bellows 20 located in the connecting sleeve 3, a sealing buckle is provided on the bellows 20, and the sealing port is similar to the sealing buckle on the swimming ring or the valve in the tire, which belongs to the prior art, and the working principle is not described in detail, the end of the bellows 20 that is away from the bellows 19 is installed with a connecting block 5, and the building block part 6 is against the surface of the connecting block 5, and the upper air cavity 22, the connecting ring 18, and the bellows 19 are interconnected and form a sealed space.

[0034] The annular containing plate 16 includes a first rigid plate 161 connected to a rotating member 23, the first rigid plate 161 is connected to a second rigid plate 162 via a flexible plate, and the end of the second rigid plate 162 away from the flexible plate is connected to a third rigid plate via a rotating member 27. When the air in the upper sealed space is insufficient, the first rigid plate 161 cannot be supported to be arranged horizontally, and will be tilted downward under the action of gravity. Moreover, the second rigid plate 162 and the third rigid plate will move downward under the action of gravity, so that the entire annular containing plate 16 is in a narrow and long state, which makes it convenient for the annular containing plate 16 to be taken out of the annular cavity 13 and inserted into the annular cavity 13, thereby facilitating the mutual installation and disassembly between the hemispheres 1 and 1.

[0035] The limiting assembly further includes an annular groove 14 and an annular cavity 13 which are provided in the other hemisphere 1 . The annular groove 14 and the annular cavity 13 are communicated with each other and matched with the annular containing plate 16 .

[0036] First, the air in the entire sealed space is controlled to a state where the annular receiving plate 16 cannot be propped up, and the annular receiving plate 16 is placed into the annular cavity 13 through the annular groove 14, and then the building block part 6 is rotated into the connecting sleeve 3. As the building block part 6 continues to enter, the connecting block 5 will be continuously squeezed. Figure 6 As shown, during the movement of the connecting block 5 in the connecting sleeve 3, the bellows 20 will be continuously squeezed, so that the sealing space is continuously reduced and the internal pressure is gradually increased. Figure 8 As shown, the entire annular containing plate 16 is slowly expanded, and then the first rigid plate 161 is pressed against the upper surface of the annular cavity 13 to complete the installation. When disassembling, the building block part 6 is rotated in the opposite direction, the sealing space is increased, and the internal pressure is reduced. Then the entire annular containing plate 16 is in a relaxed state. In addition, the flexible plate has toughness and can be squeezed and bent, so that the entire annular containing plate 16 and the connecting ring 18 can be pulled out of the annular cavity 13 and the annular groove 14 by pulling upwards, and the disassembly is completed, which is more convenient to use.

[0037] In addition, the depth of the building block part 6 entering the connecting sleeve 3 can be controlled to control the size of the sealed space volume, thereby controlling the friction between the first rigid plate 161 and the upper surface of the connecting sleeve 3. If the highest degree of stability is required, the building block part 6 is rotated to the innermost part to allow the entire annular accommodating plate 16 to expand to the maximum extent and squeeze on the upper surface of the annular cavity 13, so that the friction reaches the maximum, and the entire hemispherical body 1 remains stable. If it is necessary to maintain the building block state while adjusting the rotation of the hemispherical body 1 at any time to adjust the angle of the building block when installing the building block, the depth of the building block part 6 entering the connecting sleeve 3 can be changed, so that the first rigid plate 161 is against the upper surface of the annular cavity 13, and can be rotated and adjusted under the action of external force, thereby changing the rotation angle of the hemispherical body 1. If it is necessary to maintain the state of the hemispherical body 1 that is easy to rotate, the size of the sealed space is further expanded so that the first rigid plate 161 on the annular accommodating plate 16 is just in contact with the upper surface of the annular cavity 13, and can be rotated even when receiving a small external force.

[0038] A plurality of balls 24 are arranged in the annular cavity 13, and a limiting groove 25 which counteracts the balls 24 is arranged on the outer side wall of the second rigid plate 162. Firstly, the balls 24 and the limiting groove 25 can play a limiting role. When the annular accommodating plate 16 enters the annular cavity 13, it moves vertically downward under the action of gravity and the limiting of the annular groove 14. When the limiting groove 25 is in contact with the surface of the balls 24, the annular accommodating plate 16 reaches the specified position, thereby completing the automatic alignment. On the other hand, with the support of the balls 24, the stability of the entire annular accommodating plate 16 in the annular cavity 13 can be made stronger. When the annular accommodating plate 16 rotates in the connecting sleeve 3, it not only remains stable during rotation, but also has small friction due to the arc surface contact, making it easier to rotate.

[0039] A limit plate 17 that can move up and down is installed at the bottom end of the annular accommodating plate 16. One side of the limit plate 17 is fixedly connected to a flexible tube 21 through a spring 26. One end of the flexible tube 21 passes through the third rigid plate, the connecting ring 18, the bellows 19, and the mounting hole 15 and is rotatably connected to a threaded pin 4. The threaded pin 4 is threadedly connected in the connecting block 5. A groove is provided on the end surface of the threaded pin 4. A screwdriver can be used in conjunction with it to rotate the threaded pin 4. When the threaded pin 4 is rotated inward, the flexible tube 21 will not be folded or compressed, but will be deformed into the shape of the pipeline, thereby tightening the flexible tube 21. When the force is applied, the flexible tube 21 can be moved downward. It is worth mentioning that the sealing treatment is performed between the flexible tube 21 and the third rigid plate, which belongs to the prior art and is not described in detail. The downward movement of the flexible tube 21 will drive the limiting plate 17 to move downward, thereby abutting against the bottom side wall of the annular cavity 13, which can further increase the stability of the entire annular accommodating plate 16 in the annular cavity 13. When the flexible tube 21 is reset, under the action of the spring 26, the limiting plate 17 moves upward to separate from the bottom side wall of the annular cavity 13, and the initial position of the limiting plate 17 does not contact the bottom side wall of the annular cavity 13.

[0040] like Figure 1 and Figure 7 As shown, a semi-cube 10 is installed on the hemispherical body 1, a connecting groove 12 is provided in the semi-cube 10, part of the hemispherical body 1 is located in the connecting groove 12, a mounting groove with a non-circular cross section is provided on the top side of the hemispherical body 1, and the non-circular shape here can be an ellipse, a polygon or the like, a matching assembly sleeve 7 is installed in the mounting groove, and an assembly sleeve 7 is provided with an assembly groove 8 with a non-circular cross section, and the assembly groove 8 can be an elliptical column, a polygonal column or the like, a matching connecting column is installed in the assembly groove 8, the upper end of the connecting column is located in the connecting groove 12 and is fixedly connected to the upper side wall of the connecting groove 12, the shape of the connecting column is the same as the shape of the assembly groove 8, the semi-cube 10 is installed in the assembly groove 8 through the connecting column, and since the connecting column, the assembly groove 8 and the mounting groove are all non-circular, the semi-cube 10 can be kept stable, and the motion state is the same as that of the hemispherical body 1, and as shown Figure 7 As shown, the entire space shape composed of the semi-cube 10 and the hemispherical body 1 is similar to the shape of a polygonal column, which can meet the use and matching of more building block shapes.

[0041] A protrusion 9 is installed on the bottom side wall of the mounting groove. The shape of the protrusion 9 is one of a sphere, a column, and a cone, and the diameter of the connecting column is smaller than the mounting groove. A card slot is opened on the bottom side of the connecting column. When the semi-cube 10 needs to move independently, the assembly set 7 can be removed, and then the card slot at the bottom end of the connecting column can be stuck on the protrusion 9. In this way, the semi-cube 10 can complete independent rotation, and the movement state and the movement state of the hemisphere 1 do not interfere with each other.

[0042] The semi-cube 10 is provided with a plurality of building block slots 11 matching with the building blocks. The number, shape and position of the building block slots 11 can be freely selected during production according to usage. The building block slots 11 are used to clamp the building blocks.

[0043] Two hemispheres 1 are connected with a plurality of columns 2 through a limiting assembly, and the columns 2 are also connected to each other through the limiting assembly. The hemispheres 1 and the columns 2 can be assembled to form a capsule shape to meet the needs of building block enthusiasts.

[0044] The upper limit connection device can be in the shape of a sphere, a polygonal column or a capsule. The combination and variation of various shapes can make the assembly of building blocks smoother and more convenient, and cope with more comprehensive situations.

[0045] The flexible plate, the rotating member 23 and the rotating member 27 are made of at least one of rubber, plastic, Oxford cloth, aluminum foil and PVC. The above material is the most commonly used sealing space material and is often used to make balloons. Moreover, the above material can be bent and folded and can restore its original shape.

[0046] The bottom side end surface of the limiting plate 17 is horizontally arranged, which can increase its contact area, and is provided with a layer of rubber pad, which can increase the friction when contacting the annular cavity 13, further ensuring the stability of the annular containing plate 16 when squeezing the bottom side wall of the annular cavity 13.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
