Description

Technical Field

[0001] The utility model relates to the technical field of building block toys, in particular to a building block connector and a novel children's building block. Background Art

[0002] Building blocks are usually multiple cubic solid toys (building blocks) made of wood, plastic or EVA materials, which are arranged and stacked in different ways to form a variety of shapes. They can develop children's intelligence and are an educational toy.

[0003] Existing building blocks can be directly stacked into building block models of different shapes by building block blocks, but the building block models after such stacking are not very stable. With a slight external force, the building block models are easily pushed down, and the building block blocks are scattered everywhere. In order to solve this problem, there are also connecting holes provided on multiple building block blocks, and connecting them through connecting pieces, so as to combine and construct different building block models. Most of the connecting pieces are connecting rods, and two building block blocks can only be relatively fixedly connected by connecting rods. Although it can prevent the building block modules of the building block model from being scattered everywhere, it does not have a locking function, and the angle relationship between the two building block blocks cannot be kept unchanged when they are placed at any angle. Utility Model Content

[0004] One of the purposes of the utility model is to provide a building block connector to solve the problem that the angle relationship between two building block bodies cannot be kept unchanged when the building block toys are placed at any angle.

[0005] The second purpose of the utility model is to provide a new type of children's building block to solve the problem that the angle relationship between two building blocks cannot be kept unchanged when the existing building block toys are placed at any angle.

[0006] To solve the above problems, one of the purposes of the utility model is achieved as follows:

[0007] A building block connector comprises a connector body and a locking portion arranged on the connector body;

[0008] The connector body is a hollow rod body, and a notch communicating with the interior of the connector body is provided on the side wall of the connector body; the locking portion is arranged on the outer peripheral side of the connector body.

[0009] Wherein, the two axial ends of the connector body are open.

[0010] Wherein, the notch is a strip-shaped notch, and the axial ends of the notch respectively penetrate the corresponding axial ends of the connector body.

[0011] Wherein, the axial direction of the notch is parallel to the axial direction of the connector body.

[0012] Wherein, the locking portion includes a locking protrusion protruding from the outer peripheral side of the upper connector body, and the number of the locking protrusion is one or more.

[0013] Wherein, the locking protrusion is a strip-shaped protrusion.

[0014] Wherein, the axial direction of the locking protrusion is parallel to the axial direction of the connecting piece body.

[0015] Wherein, a chamfer is provided on the outer peripheral side of at least one axial end of the connecting member body.

[0016] The second purpose of the utility model is achieved in this way:

[0017] A novel children's building block comprises at least two building block bodies and the above-mentioned building block connector. The building block bodies are provided with connecting holes for accommodating the building block connector to pass through, and at least two building block bodies are fixedly connected through the matching of the building block connector and the connecting holes.

[0018] The beneficial effects of the utility model are:

[0019] The hollow connector body and the notch connected to the inside together form a void avoidance structure, which can play an elastic role. When the building block needs to be inserted, it only needs to squeeze the connector body to insert it into the connecting hole of the building block. When the hollow connector body is inserted into the connecting hole of the building block, it automatically rebounds and sticks to the inner wall of the connecting hole of the building block. In general, the design of the void avoidance structure can reserve space for the axial connector body to be designed to be elastically deformed when inserted into the connecting hole. In addition, after the connector body is inserted into the connecting hole of the building block, the locking protrusion can contact the inner surface of the connecting hole to provide the necessary friction force to maintain the building block at a predetermined angle.

[0020] The utility model can make the building blocks rotate at any angle under the action of the connecting member body by ingeniously combining the hollow connecting member body, the notch and the locking protrusion. And without adding an additional angle damping mechanism, the angle relationship between different building blocks can be maintained when placed at a predetermined angle, which reduces the cost and processing difficulty, solves the problem of realizing rotation angle damping and processing of shaft-type connection on the basis of reasonable cost, and realizes the maintenance of the relative angle relationship between different building blocks.

[0027] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0028] Embodiment 1:

[0029] like Figure 1 , Figure 2 As shown, a building block connector of the utility model includes a connector body 1 and a locking portion arranged on the connector body 1. The connector body 1 is a hollow shaft body, and the cross section of the shaft body perpendicular to the axial direction is a geometric shape, but is not limited to a circle. It can be a regular geometric shape such as a square, a rectangle, an ellipse, a triangle, or an irregular geometric shape. In this embodiment, the cross section of the shaft body perpendicular to the axial direction is selected to be circular. A notch 2 connected to the interior of the connector body 1 is provided on the side wall of the connector body 1. The connector body 1 is open at both axial ends. The notch 2 is a strip-shaped notch 2, and the axial ends of the notch 2 respectively pass through the corresponding axial ends of the connector body 1. The axial direction of the notch 2 can be parallel to the axial direction of the connector body 1, or it can be non-parallel to the axial direction of the connector body 1. Refer to Figure 3 In this embodiment, the hollow connector body 1 and the notch 2 connected to the inside thereof together constitute a void avoidance structure, which can play an elastic role. When the building block 5 needs to be inserted, the connector body 1 only needs to be squeezed to narrow the notch 2, and then the connector body 1 can be inserted into the connection hole 6 of the building block 5. When the hollow connector body 1 is inserted into the connection hole 6 of the building block 5, it automatically rebounds and sticks to the inner wall of the connection hole 6 of the building block 5. In general, the design of the void avoidance structure is intended to reserve space for the shaft-type connector body 1 to be elastically deformed when inserted into the connection hole 6, and the magnitude of the elastic deformation force is controlled by the reserved space and the material thickness and strength of the shaft-type connector body 1.

[0030] The locking portion is arranged on the outer peripheral side of the connector body 1. The locking portion includes a locking protrusion 3 protruding from the outer peripheral side of the connector body 1. The number of the locking protrusions 3 is one or more. The function of the locking protrusion 3 is: after the connector body 1 is inserted into the connecting hole 6 of the building block 5, it contacts the inner surface of the connecting hole 6 to provide the necessary friction force, and controls the size of the friction force by controlling the area and number of the locking protrusions 3, and cooperates with the elastic deformation of the air-avoiding structure of the connector body 1 to exert outward tension to maintain the angle relationship. The shape, number, and distribution of the locking protrusion 3 are not restricted, and the purpose is to provide sufficient friction force to lock the connector body 1 in the connecting hole of the building block as needed. In the present embodiment, the locking protrusion 3 is a strip protrusion, and the number of the strip protrusions is one or more. The axial direction of the locking protrusion 3 is parallel to the axial direction of the connector body 1. This design is relatively regular and convenient for processing and production. In one of the schemes (reference Figure 1 ), there are two strip-shaped protrusions, and the two strip-shaped protrusions are arranged opposite to each other in the radial direction.

[0031] A chamfer 4 is provided on the outer peripheral side of at least one axial end of the connector body 1. In this embodiment, chamfers 4 are provided on the outer peripheral sides of both axial ends of the connector body 1. The chamfer 4 can play a guiding role when the connector body 1 is inserted into the connecting hole, so that the connector body 1 can be more easily and smoothly inserted into the connecting hole and elastically deformed.

[0032] Embodiment 2:

[0033] like Figure 3 As shown, a new type of children's building block of the utility model comprises at least two building blocks 5 and a building block connector of the first embodiment. The building block 5 is provided with a connecting hole 6 for accommodating the building block connector to pass through. At least two building blocks 5 are fixedly connected by the building block connector and the connecting hole 6. Specifically, in combination with Figure 1-Figure 2 A connecting hole 6 for cooperating with the connector body 1 of the building block connector is provided on the building block 5, and then the connector body 1 is squeezed to narrow the width of the notch 2 (i.e., the connector body 1 is tightened), and then the connecting hole 6 of the building block 5 to be penetrated is smoothly passed under the guidance of the chamfer 4, the two connected building blocks 5 are rotated to the required angle, and then the connector body 1 is released. Under the action of elastic deformation, the connector body 1 rebounds, and the locking protrusion 3 arranged thereon is pressed against the hole wall of the connecting hole 6 under the action of friction, so that the connector body 1 is stuck on the hole wall of the connecting hole 6 of the building block 5.

[0034] The utility model can make the building blocks rotate at any angle under the action of the connecting member body by ingeniously combining the hollow connecting member body, the notch and the locking protrusion. And without adding an additional angle damping mechanism, the angle relationship between different building blocks can be maintained when placed at a predetermined angle. The problem of rotation angle damping and processing error of the shaft-type connection is solved on the basis of reasonable cost, and the relative angle relationship between different building blocks is maintained.

[0035] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
