[0002] With the diversification requirements of the building block toy market, more and more building block toy shapes have been designed in the prior art, especially some building block toys in the shape of human figures, which are widely loved by people.

[0003] Some parts of building block toys often have long lengths, such as the limbs of human-shaped building blocks. These structures often use a ball-and-socket joint structure to achieve both connection and joint rotation. Due to the relatively smooth surfaces of the ball and socket, this joint structure is prone to sagging under the weight of the connecting parts. While existing technologies have employed anti-slip grooves or manipulated material properties to increase frictional damping at the joint, these effects are limited and can negatively impact the joint's rotational flexibility when deformation is required.

[0004] For this reason, it is necessary to design a splicing piece of a building block splicing toy that can meet the above problems. Utility Model Content

DETAILED DESCRIPTION

[0034] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this solution.

[0035] Example 1

[0036] like Figures 1 to 12 As shown, this embodiment designs a splicing piece of a building block splicing toy, which adopts an A-shaped clamp structure. The splicing piece includes a first clamping petal 1, a second clamping petal 2 and a U-shaped elastic piece (not shown in the figure). The two ends of the U-shaped elastic piece are connected to the first clamping petal 1 and the second clamping petal 2, thereby splicing the first clamping petal 1 and the second clamping petal 2 together.

[0037] The middle portion of the first clamping petal 1 is rotatably connected to the middle portion of the second clamping petal 2. The front portions of the first clamping petal 1 and the second clamping petal 2 have clamping heads, and the rear portions of the first clamping petal 1 and the second clamping petal 2 have clamping handles. Specifically, the clamping head of the first clamping petal 1 is a first clamping head 11, and the clamping handle of the first clamping petal 1 is a first clamping handle 13. A first rotating portion 12 is provided in the middle portion of the first clamping petal 1. The first rotating portion 12 is located between the first clamping head 11 and the first clamping handle 13, and is used to rotatably connect to the second rotating portion 22 of the second clamping petal 2. The clamping head of the second clamping petal 2 is a second clamping head 21, and the clamping handle of the second clamping petal 2 is a second clamping handle 23. A second rotating portion 22 is provided in the middle portion of the second clamping petal 2. The second rotating portion 22 is located between the second clamping head 21 and the second clamping handle 23, and is used to rotatably connect to the first rotating portion 12 of the first clamping petal 1.

[0038] The first rotating part 12 and the second rotating part 22 are connected through a rotating shaft; or, the first rotating part 12 and the second rotating part 22 are matched with each other on curved surfaces to form a mutual rotation connection relationship, that is, a semicircular groove is provided on the first rotating part 12, and a semicircular head is provided on the first rotating part 12, and the semicircular groove and the semicircular head are engaged with each other.

[0039] Notches are provided on the opposing inner sides of the clamping heads of the first and second clamping petals 1 and 2, specifically, on the opposing inner sides of the first clamping head 11 and the second clamping head 21. A spherical head 15 is fixedly connected to the handle end of the first clamping petal 1. The spherical surface of the spherical head 15 corresponds to the shape of the notch, allowing the notch to engage with the spherical surface of the spherical head 15 of the other connecting piece. This structural form not only increases the reliability of the connection between the two, but also reduces the probability of the two connecting pieces falling off after connection. It also facilitates the connection of the two connecting pieces in a variety of connection configurations, such as straight and curved, to meet the different usage requirements of the building block toy.

[0040] The spherical head 15 is fixedly connected to the first clamping piece 1. Specifically, the spherical head 15 and the first clamping piece 1 are fixedly connected via a connecting post 14. The connecting post 14 is L-shaped, and the part where the connecting post 14 connects to the spherical head 15 is located directly behind the rotational connection between the first clamping piece 1 and the second clamping piece 2, thereby reducing the impact of the connecting post 14 on the connection of the clamping head of another splicing piece.

[0041] The spherical head 15 is provided with a plurality of first protruding teeth; tooth grooves are formed between adjacent first protruding teeth. The tooth grooves on the spherical head 15 include a plurality of transverse annular grooves and a plurality of vertical annular grooves. The transverse annular grooves and the vertical annular grooves are perpendicular to each other. The planes on which any two transverse annular grooves lie are parallel to each other, and the planes on which any two vertical annular grooves lie are parallel to each other. No second protruding teeth are provided on the notch of the first clamping petal.

[0042] The second jaw has two structural forms. In the first structural form, the second jaw has a second protruding tooth disposed inside the recess, while in the second structural form, the second jaw has no second protruding tooth disposed inside the recess. The second protruding tooth can engage with the tooth groove of the first protruding tooth. The first protruding tooth can be in the shape of a polygonal prism, and the second protruding tooth 24 can also be in the shape of a polygonal prism.

[0043] The first clamping flap and the second clamping flap are detachably connected to realize the replacement of the two structural forms of the second clamping flap, so that the second clamping flap connected to the first clamping flap can be any one of its two structural forms. The splicing piece with the second protruding teeth can be connected with the spherical head 15 of the other splicing piece in an occlusal fit, and the splicing piece without the second protruding teeth can be connected with the spherical head 15 of the other splicing piece in a damping fit.

[0044] When the clamping head of the splicing piece with the second convex tooth needs to be connected to the spherical head 15 of another splicing piece, a second convex tooth 24 can be set on the inner side of the recess of the first clamping petal 1 or the second clamping petal 2 of the splicing piece, and the second convex tooth 24 can be engaged with the tooth groove of the second convex tooth 24 on the spherical head 15 of the other splicing piece.

[0045] When the clamp of the splicing piece without the second protruding teeth needs to be connected to another splicing piece or other components, since the second protruding teeth 24 are not provided on the inner side of the recesses of the first clamping petal 1 and the second clamping petal 2 of the splicing piece, the clamps of the two splicing pieces and the spherical heads can achieve a mutually damping-enhancing and movable connection relationship.

[0046] In this embodiment, the protruding teeth on the spherical head 15 engage with the tooth grooves of the protruding teeth on the chuck, effectively improving the reliability of the spliced ​​parts after connection and facilitating the maintenance of the connected state of the two spliced ​​parts. Furthermore, the depth of the recess is greater than the height of the second protruding teeth 24 and the first protruding teeth. Therefore, when the second protruding teeth 24 and the first protruding teeth begin to disengage, the recess of the chuck and the spherical surface of the spherical head 15 remain engaged, allowing the chuck and spherical head 15 to maintain a connection and also enable rotation (rotation along the horizontal or vertical annular groove).

[0047] The above embodiments are merely examples for the purpose of illustrating the present invention clearly and are not intended to limit the embodiments. It is not necessary and impossible to enumerate all embodiments here. Obvious changes or modifications derived therefrom are still within the scope of protection of this technology.
