Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The modular assembly dome toy provided by this utility model includes 6 identical regular pentagonal pyramid modules. One of the regular pentagonal pyramid modules is the top regular pentagonal pyramid module, and the other 5 regular pentagonal pyramid modules are the peripheral regular pentagonal pyramid modules. Each bottom corner of the top regular pentagonal pyramid module is connected to a bottom corner of each peripheral regular pentagonal pyramid module through a second connecting unit. The peripheral regular pentagonal pyramid modules are connected to each other at adjacent bottom corners through the second connecting unit. The regular pentagonal pyramid modules form a hemispherical dome.

[0028] In some embodiments of this utility model, each regular pentagonal pyramid module is composed of five identical first sheets, each first sheet being an isosceles triangle. The five first sheets are connected at their apex by a first connecting unit to form one regular pentagonal pyramid module. Thirty first sheets 100 together form one top regular pentagonal pyramid and five peripheral regular pentagonal pyramids. Specifically, as... Figure 1 As shown, the first sheet 100 is an isosceles triangle. Every five first sheets 100 are connected by their vertices abutting each other and their sides are adjacent to each other, forming a regular pentagonal pyramid. The five first sheets 100 form the five lateral faces of the regular pentagonal pyramid. Thirty first sheets 100 are arranged in the above manner to form six identical regular pentagonal pyramids. One of these regular pentagonal pyramids serves as the top regular pentagonal pyramid module 101, and the remaining five regular pentagonal pyramids serve as the peripheral regular pentagonal pyramid modules 102. Each base corner of the top regular pentagonal pyramid module 101 is connected to a base corner of one of the peripheral regular pentagonal pyramid modules 102 via a second connecting unit 600. The five peripheral regular pentagonal pyramid modules 102 are connected at adjacent base corners via the second connecting unit 600.

[0029] like Figure 1As shown, the apex of the top regular pentagonal pyramid module 101 is connected by the first connecting unit 500, and the five base corners are connected by the second connecting unit 600. That is, the apex corners of the five first sheets 100 that make up the top regular pentagonal pyramid module 101 are connected by the first connecting unit 500, and the adjacent base corners of the five first sheets 100 are connected by the second connecting unit 600. The apex corners of the peripheral regular pentagonal pyramid module 102 are connected by the first connecting unit 500, and the one base corner that abuts against the top regular pentagonal pyramid module 101 and the two base corners that abut against the adjacent peripheral regular pentagonal pyramid module 102 are all connected by the second connecting unit 600. That is, the apex corners of the five first sheets 100 that make up the peripheral regular pentagonal pyramid module 102 are connected by the first connecting unit 500, and the base corners between the four first sheets 100 that abut against the top regular pentagonal pyramid module 101 and the adjacent peripheral regular pentagonal pyramid module 102 are connected by the second connecting unit 600. The first sheet 100 of the peripheral regular pentagonal pyramid module 102 does not abut against the top regular pentagonal pyramid module 101 or the adjacent peripheral regular pentagonal pyramid module 102. That is, the bottom corner of the first sheet 100 at the bottom is connected to the bottom corner of the adjacent first sheet 100 on both sides through the third connecting unit 700, which strengthens the overall stability of the dome structure.

[0030] In some embodiments of this utility model, it further includes 10 identical second sheets 200, such as... Figure 2 , 3 As shown, the second sheet 200 is an equilateral triangle, and the side length of the second sheet 200 is equal to the base length of the first sheet 100. There are two gaps 103 at the top and bottom between two adjacent peripheral regular pentagonal pyramid modules 102. A total of 10 gaps 103 are formed between the 5 peripheral regular pentagonal pyramid modules 102. The 10 second sheets 200 are respectively set at the 10 gaps 103. Two sides of the second sheet 200 are adjacent to the base edge of the first sheet 100 in the adjacent peripheral regular pentagonal pyramid module 102. The second sheet 200 set at the upper gap 1031 also has one side adjacent to the corresponding base edge of the top regular pentagonal pyramid module 101.

[0031] Each bottom corner of the second sheet 200 located at the upper gap 1031 is connected to the bottom corner of the adjacent first sheet 100 through the second connecting unit 600; one bottom corner of the second sheet 200 located at the lower gap is connected to the bottom corner of the adjacent first sheet 100 through the second connecting unit 600, and the other two bottom corners are connected to the bottom corner of the adjacent first sheet 100 through the third connecting unit 700.

[0032] Furthermore, this embodiment of the invention also includes 10 identical third sheets 300. Each third sheet 300 is rectangular, and the length of its first connecting edge is equal to the side length of the second sheet 200. Since the length of the bottom edge of the first sheet 100 is also equal to the length of the side length of the second sheet 200, the length of its first connecting edge is also equal to the length of the bottom edge of the first sheet 100. The third sheets 300 are vertically arranged, and their first connecting edges are aligned with the first sheet 100 and the second sheet 200 at the bottom of the hemispherical dome, respectively, and connected by a fourth connecting unit 800. The third sheets 300 enclose and form a support wall 301.

[0033] In some embodiments of this invention, one second sheet 200 can be removed from the lower gap 1032, and the gap 103 without the second sheet 200 forms a passageway 400 connecting the inside and outside of the dome structure. Similarly, in some embodiments with a support wall 301, one third sheet 300 is correspondingly removed, and no third sheet 300 is provided below the gap 103 without the second sheet 200, thus forming a passageway 400.

[0034] In some embodiments of this utility model, the first connecting unit 500 includes a first connecting piece 501 and a fastening unit 900. The first connecting piece 501 is provided with five first connecting surfaces 502.

A fastening hole 920 is also provided at the corresponding position of the first connecting surface 502 of the first connecting piece 501. The fastening hole 920 and the fastener 910 cooperate to form the fastening unit 900. Specifically, the fastener 910 is used to pass through the fastening hole 920 on the first connecting piece 501 and the first sheet 100 to achieve a fastening connection.

[0035] The second connecting unit 600 includes a second connecting piece 601 and a fastening unit 900. The second connecting piece 601 has six second connecting surfaces 602, and the included angle between the second connecting surfaces 602 is the same as the included angle between the sides of a regular pentagonal pyramid at its base corner. Similar to the first connecting unit 500, the second connecting piece 601 is also located inside the dome structure. A fastening hole 920 is provided at the base corner of the first sheet 100, and a fastening hole 920 is also provided at the corresponding position of the second connecting surface 602 of the second connecting piece 601. The fastening holes 920 and the fasteners 910 cooperate to form the fastening unit 900.

[0036] The third connecting unit 700 includes a third connecting piece 701 and a fastening unit 900. The third connecting piece 701 has five third connecting surfaces 702, and the included angle between the third connecting surfaces 702 is the same as the included angle at the connection point of the first sheet 100, the second sheet 200, and the third sheet 300. Similar to the first connecting unit 500, the third connecting piece 701 is also located inside the dome structure. Fastening holes 920 are provided at the bottom corner of the third sheet 300 and at the four corners of the fourth sheet. Fastening holes 920 are also provided at corresponding positions on the third connecting surfaces 702 of the third connecting piece 701. The fastening holes 920 and the fasteners 910 cooperate to form the fastening unit 900.

[0037] The fourth connecting unit 800 includes a fourth connecting piece 801 and a fastening unit 900. The fourth connecting piece 801 is provided with two fourth connecting surfaces 802, and the included angle between the fourth connecting surfaces 802 is the same as the included angle between the third sheets 300. In some embodiments of this utility model, in order to enhance the stability of the supporting wall 301, the fourth connecting piece 801 is also added with a placement surface 803 parallel to the placement plane, such as... Figure 3 , 4 As shown. The fastening unit 900 included in the fourth connecting unit 800 is similar to the fastening unit 900 described above, and will not be described again.

[0038] In some embodiments of this utility model, the fastener 910 is a bolt 911 and a nut 912. The bolt 911 passes through the fastening hole 920 and the nut 912 is tightened to achieve a fastening connection. In other embodiments, the fastener 910 can be configured as a retaining post 913 and a retaining ring 914. The retaining post 913 passes through the fastening hole 920 and is then secured by the retaining ring 914 to achieve a fastening connection.

[0039] In some embodiments of this utility model, the fastening unit 900 can be magnetically attracted. Specifically, a first magnetic attractor is provided in the top corner of the first, second, and third sheets, and a second magnetic attractor is correspondingly provided in the first, second, third, and fourth connecting pieces. The first magnetic attractor and the second magnetic attractor magnetically attract each other to achieve a fastening connection.

[0040] In some embodiments of this utility model, rod-shaped materials are used instead of sheet materials, enriching the material forms while maintaining the same construction logic. Specifically, the regular pentagonal pyramid module is composed of 5 edge rods 1001 and 5 base rods 1002. One end of the 5 edge rods 1001 is connected by a first connecting unit 500 to form the edges of the regular pentagonal pyramid. The 5 base rods 1002 are located at the base of the regular pentagonal pyramid. The regular pentagonal pyramid composed of the edge rods 1001 and the base rods 1002 is then used to form a hemispherical dome according to the above construction logic. Furthermore, reinforcing rods 1003 are provided between the bottom corners below the peripheral regular pentagonal pyramid module 102. The reinforcing rods 1003 are connected to the corresponding edge rods 1001 and base rods 1002 through a third connecting unit 700.

The base plate 1101 and the clamping plate 1102 are fastened together by fasteners 910 and clamp the connecting pipe 1103 set in the middle. The inner diameter of the connecting pipe 1103 is equivalent to the outer diameter of the rib rod 1001, the bottom rod 1002, the reinforcing rod 1003, and the support rod 1004. After the rib rod 1001, the bottom rod 1002, the reinforcing rod 1003, and the support rod 1004 are inserted into the connecting pipe 1103, they form a connection with the corresponding connecting unit. The end of the connecting pipe 1103 clamped by the base plate 1101 and the clamping plate 1102 is also provided with an anti-detachment platform 1104. The clamping plate 1102 is provided with an anti-detachment hole 1105, and the anti-detachment platform 1104 is embedded in the anti-detachment hole 1105.
