[0061] The present utility model will be described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present utility model, but do not limit the present utility model in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several changes and improvements can still be made. These all belong to the protection scope of the present utility model.

[0062] Embodiment 1:

[0063] The present utility model provides a building block joint structure, as Figure 1 shown, including a first building block 1, a second building block 2, and a third building block 3. In this embodiment, the third building block 3 is a body building block, and the building block joint structure is arranged at the head and neck. The lower end of the first building block 1 is configured with a first structure 11, and the upper end of the second building block 2 is configured with a second structure 21 that matches the first structure 11. Both the first structure 11 and the second structure 21 are building block splicing structures, and the first structure 11 and the second structure 21 can be connected or separated by splicing. Due to the matching splicing relationship between the first structure 11 and the second structure 21, the first building block 1 can be spliced at the upper end of the second building block 2 and can rotate left or right relative to the second building block 2 but is not allowed to rotate forward or backward, realizing the action of turning the head left and right.

[0064] Furthermore, the lower end of the second building block 2 is configured with a third structure 22, and the upper end of the third building block 3 is configured with a fourth structure 31 that matches the third structure 22. Due to the matching splicing relationship between the third structure 22 and the fourth structure 31, the lower end of the second building block 2 can be spliced at the upper end of the third building block 3 and can rotate forward or backward relative to the third building block 3 but is not allowed to rotate left or right, realizing the actions of lowering the head and leaning backward. Among them, the maximum angle of the second building block 2 rotating forward relative to the third building block 3 is greater than the maximum angle of rotating backward. The maximum angle of the second building block 2 rotating forward relative to the third building block 3 is α. For example, α is 100°, and α is preferably 70°. The maximum angle of rotating backward is β. For example, β is 90°, and β is preferably 45°, as Figure 9 、 Figure 10 shown. In actual applications, the building block joint structure often cooperates with external clothes and armors to form a doll shape. Due to the wearing of clothes and armors, the building block joint structure may be interfered or restricted by the clothes during movement, resulting in a smaller original rotation angle. Therefore, when designing, the specific use scenario of the toy must be considered, such as adjusting the maximum angles of lowering the head and leaning backward. For example, the maximum angle of lowering the head is designed to be 60°, and the maximum angle of leaning backward is designed to be 40°, etc., as Figure 3 、 Figure 4 are respectively the situations where the head is lowered and raised by 20°.

[0065] As Figure 1 、 Figure 2As shown, the first structure 11 is a splicing board, and splicing holes 111 are arranged on the splicing board. The second structure 21 is a splicing groove, and splicing bosses 211 are respectively arranged on the inner walls of both sides of the splicing groove. The two splicing bosses 211 are arranged opposite to each other and there is a splicing gap between them. When splicing, the end of the splicing board can pass through the splicing gap, and then the end of the splicing boss 211 can be spliced into the splicing hole 111. Specifically, the width of the splicing gap is slightly smaller than the thickness of the splicing board. Driven by hand force, the splicing gap allows the end of the splicing board to pass through the splicing gap, and then the splicing boss 211 can enter the splicing hole 111. The process of the splicing board passing through the splicing gap is a process of elastic deformation. The two splicing bosses 211 are first elastically expanded and then restored to their original positions, so that the first building block 1 and the second building block 2 spliced together can be stably connected and are not easily separated in the natural state, increasing the stability of the toy.

[0066] In this embodiment, the splicing groove limits the left and right rotation ranges of the first building block 1 by the interference of the groove walls on the left and right sides on the first building block 1. When the first building block 1 swings to the left, when the leftmost side of the first building block 1 interferes with the left groove wall of the splicing groove, the first building block 1 rotates to the maximum angle on the left; when the first building block 1 swings to the right, when the rightmost side of the first building block 1 interferes with the right groove wall of the splicing groove, the first building block 1 rotates to the maximum angle on the right. It should be noted that in the present utility model, the maximum angle of the first building block 1 rotating to the left relative to the second building block 2 is equal to the maximum angle of rotating to the right, and the maximum angle of rotating to the left and the maximum angle of rotating to the right are both θ. For example, θ is 90°, and θ is preferably 60°, such as Figure 7 、 Figure 8 As shown, it can also be designed as a slightly smaller angle, such as 50°, 45°, etc., such as Figure 5 、 Figure 6 are respectively the situations where the left head swing and the right head swing are 20°.

[0067] Such as Figure 1 As shown, the third structure 22 includes a building block body 221 and building block shafts 222 respectively arranged on the left and right sides of the building block body 221. The fourth structure 31 includes a receiving space 311 and rotating grooves 312 arranged on both sides of the receiving space 311. The receiving space 311 is communicated with the rotating grooves 312. When the third structure 22 is spliced into the fourth structure 31, the building block shafts 222 are located in the rotating grooves 312 and can rotate in the rotating grooves 312, thereby realizing the forward or backward rotation of the second building block 2 and realizing the actions of lowering the head or leaning back.

[0068] When the building block shaft 222 is spliced into the rotation groove 312, the lower end of the building block body 221 extends into the accommodation space 311. The width of the top opening of the rotation groove 312 is slightly smaller than the outer diameter of the building block shaft 222. Driven by hand force, the building block shaft 222 can pass through the top opening of the rotation groove 312 and enter the rotation groove 312, making it not easy for the building block shaft 222 spliced into the building block groove 312 to come out, increasing the stability of the toy. It should be noted that when the building block shaft 222 rotates in the rotation groove 312, the accommodation space 311 limits the forward or backward rotation range of the second building block 2 by interfering with the building block body 221 through the inner walls on both the front and rear sides. In practical applications, the inner walls of the accommodation space 311 can also be designed as planes, arc surfaces, etc. to achieve corresponding functional requirements, and the inner walls of the accommodation space 311 can also be designed into other shapes to meet the requirements of the rotation angle.

[0069] In practical applications, when the second building block 2 rotates forward relative to the third building block 3 to the maximum angle, the building block body 221 is in sealing fit with the front inner wall of the accommodation space 311; and / or when the second building block 2 rotates backward relative to the third building block 3 to the maximum angle, the building block body 221 is in sealing fit with the rear inner wall of the accommodation space 311. When rotating to the maximum angle, the building block body 221 can be in sealing fit with the inner wall of the accommodation space 311, making the toy seamless when observed from the outside, with a more beautiful appearance and a more advanced sense visually, enhancing the interest of the toy.

[0070] The upper end of the first building block 1 is provided with a head splicing structure 12, and the head splicing structure 12 is used for splicing the head building block 4. The head splicing structure 12 is preferably a ball head or ball socket structure. By adopting the structure of a ball head cooperating with a ball socket when the upper end of the first building block 1 is spliced with the head building block 4, the head building block 4 has the freedom to adjust in all directions at the upper end of the first building block 1, making the posture of the toy more diverse and increasing the interest of the toy.

[0071] The present utility model also provides a doll, including a building block joint structure. For example, the doll is a Transformers doll. It should be noted that the building block joint structure in the present utility model can not only be applied to the head and neck of the doll, but also to other parts, such as the shoulder joint. In Transformers, it can realize the rotation of the shoulder joint in all directions, increasing the interest of the toy. In other application scenarios, a rotational resistance can also be set between the first building block 1 and the second building block 2, and between the second building block 2 and the third building block 3, so that the spliced doll can manually adjust its posture and maintain the original posture in the natural state.

[0072] Embodiment 2:

[0073] In this embodiment, the upper end of the second building block 2 is configured with a second structure 21 matching the first structure 11, so that the lower end of the first building block 1 is connected to the upper end of the second building block 2 and can be rotated left or right relative to the second building block 2 and is not allowed to rotate forward and backward. Different from Example 1, the first structure 11 and the second structure 21 are connected by injection molding, and the two are not allowed to be separated.

[0074] Specifically, the first structure 11 is a plate-like structure with through holes, and the second structure 21 is a groove-like structure. A rotating shaft 212 is disposed in the middle of the groove-like structure. Figure 11 As shown, the rotating shaft 212 passes through the through hole by injection molding so that the first structure 11 is connected to the second structure 21 .

[0075] Embodiment 3:

[0076] The difference between this embodiment and the first embodiment is that the two sides of the upper end of the third building block 3 are respectively provided with a limiting platform 32. Figure 7 , Figure 8 As shown, the left-right rotation range of the first building block 1 is limited by the interference of the two limiting platforms 32 on the first building block 1 .

[0077] In this embodiment, the first building block 1 and the head building block 4 adopt a male head matching female head structure, which can also meet the needs of building a variety of doll characters.
