Description

Technical Field

[0001] The invention belongs to the technical field of assembled models and relates to a connection structure for assembling models. Background Art

[0002] There are various types of assembled action figures or building block toys on the market, among which Lego is a relatively mature design. A major feature of this type of model toy products is that they are equipped with a variety of different types of parts, and each part is provided with a unified and universal column hole plug-in structure, snap structure and other connecting structures to support the free combination of parts with no specific upper limit to form a variety of overall structures. However, due to the structural shape and size of the parts, the softness and hardness of the materials, etc., the connection strength and tightness of the connection structure of existing products of this type are limited. In particular, when the size of the parts is small, the processing accuracy of the connection structure is limited, and there will be large processing dimensional errors, which will lead to inadequate connection matching and need to be further fixed by glue. The splicing operation of the entire model toy is too cumbersome and the reliability of the splicing strength cannot be guaranteed. Summary of the invention

[0006] Furthermore, a convex rib is arranged on the inner periphery of the limiting groove, and a groove for clamping the convex rib is arranged on the outer periphery of the limiting column.

[0008] Furthermore, a groove is concavely provided on the outer periphery of the limiting column, and an inner wall on one side of the groove is formed as a first inclined surface. A ramp is protrudingly provided on the inner periphery of the limiting groove, and an outer wall of the ramp forms a second inclined surface. When the limiting column is plugged into the limiting groove, the ramp is inserted into the groove, and the first inclined surface and the second inclined surface form a surface contact fit.

[0009] Furthermore, the first limiting plane is set as the inner wall of the other side of the cutting groove, and the first limiting plane forms a set acute angle with the first inclined surface.

[0010] Furthermore, the first inclined surface and the second inclined surface are respectively provided with reinforcement grooves and reinforcement ribs, and when the limiting column is plugged into the limiting groove, the reinforcement ribs are clamped into the reinforcement grooves.

[0031] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0032] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0033] All directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, horizontal, vertical...) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0034] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of the present invention may actually be an approximately parallel relationship, and the vertical relationship may actually be an approximately vertical relationship.

[0035] The invention provides a connection structure for assembling models, comprising a first connection part and a second connection part. By setting a combination of the first connection part and the second connection part, a fast and stable connection between a plurality of components to be connected that can be repeatedly disassembled can be achieved.

[0036] The first connection part can be set on any one of the parts to be connected in the model toy alone, or the second connection part can be set alone, or the first connection part and the second connection part can be set at the same time, so that it can be freely combined and connected with any other one or more other different parts to be connected with corresponding matching connection parts. The partial connection state can refer to Figure 1 , Figure 2 and Figure 3 .

[0037] Specifically, refer to Figure 4 , Figure 5 and Figure 6 The first connecting portion includes a first limiting plane 11 and a limiting column 1. The limiting column 1 is protruded on the first limiting plane 11 with a set thickness. At the same time, the limiting column 1 has a set length and a set width in a direction parallel to the first limiting plane 11.

[0038] Reference Figure 7 , Figure 8 and Fig. 9 The second connecting part includes a limiting groove 2, and the limiting groove 2 is a U-shaped structure with an inward concave arrangement to form an open opening for the limiting column 1 of the first connecting part to enter, wherein the first connecting part and the second connecting part are plugged and combined along the direction of the set length, so that the outer end of the limiting column 1 in the set length direction first enters the limiting groove 2 from the open opening until it is located inside the limiting groove 2, and can contact and abut against the bottom of the U-shaped structure, and the inner end of the limiting column 1 in the set length direction is matched with the open opening of the limiting groove 2, and in the set width direction, the outer periphery of the entire limiting column 1 and the inner periphery of the limiting groove 2 form a surface-to-surface contact fit, or even an interference fit, which effectively utilizes the space to increase the connection fit area and improve the connection strength.

[0039] The left and right side walls in the limit groove 2 near the open opening are respectively provided with convex ribs 21 which are protruded opposite to each other, and the left and right side walls at the inner end in the set length direction of the limit column 1 are respectively provided with grooves 12 which are recessed opposite to each other. When the limit column 1 is set into place in the limit groove 2, the convex ribs 21 on both sides are respectively squeezed and snapped into the grooves 12 on both sides to form a snap-fit ​​fit, thereby forming a connection limit for the first connecting part and the second connecting part in the set width direction and the set length direction.

[0040] The convex rib 21 is connected with the side wall of the limiting groove 2 with a concave arc surface 22, and the groove 12 is connected with the side wall of the limiting column 1 with a corresponding convex arc surface 13. When the convex rib 21 is snap-fitted with the groove 12, the concave arc surface 22 and the convex arc surface 13 simultaneously form a surface-to-surface contact, effectively increasing the contact area, thereby enhancing the connection strength.

[0041] Furthermore, when the limit column 1 and the limit groove 2 are in place, one end of the second connection part along the set thickness direction is set as a plane abutting against the first limit plane 11, thereby forming a connection limit for the first connection part and the second connection part in the set thickness direction through abutment.

[0042] The parts to be connected and the connecting buckles in this embodiment are preferably injection molded parts. After the parts to be connected are connected by the first connecting part and the second connecting part, they will be affected by other multi-directional external forces. Due to the fatigue strength of the limiting column 1, deformation or even breakage may easily occur, especially at the position between the limiting column 1 and the first limiting plane 11. As an improvement, a bevel connection structure is also provided in this embodiment.

[0043] The inclined surface connection structure includes a first inclined surface 14 arranged on the limiting column 1 and a second inclined surface 23 arranged on the limiting groove 2, wherein the left and right side walls on the set width direction on the limiting column 1 are respectively recessed inwardly and are set as a cutting groove structure, and the first inclined surface 14 is set as the inner wall of the cutting groove. Preferably, the first inclined surfaces 14 on both sides are symmetrical; the left and right side walls on the set width direction on the limiting groove 2 are respectively protruding outwardly and are set as a ramp structure, and the second inclined surface 23 is set as the outer wall of the ramp, and the inclination of the first inclined surface 14 and the second inclined surface 23 is the same.

[0044] When the limit column 1 is connected with the limit groove 2, the inclined platform is inserted into the groove along the set length direction, so that the first inclined surface 14 and the second inclined surface 23 are in surface contact. The abutment setting of the double inclined surfaces allows the force acting on the limit column 1 to be dispersed in two directions, namely, the set width direction and the set thickness direction, through the inclined surfaces, thereby effectively reducing the excessive local pressure of the limit column 1, reducing the deformation and fracture of the limit column 1, and ensuring a stable connection.

[0045] Furthermore, the first limiting plane 11 is set as the inner wall of the other side of the groove, so that the first inclined surface 14 is opposite to the first limiting plane 11 and forms a groove with a set angle, and the angle is an acute angle. The other side of the inclined platform is set as the bottom surface, and the bottom surface is abutted against the first limiting plane 11 to provide support and limitation in the set thickness direction.

[0046] A recessed reinforcement groove 15 and a protruding reinforcement rib 24 are respectively provided on the first inclined surface 14 and the second inclined surface 23. When the limiting column 1 and the limiting groove 2 are installed in place, the reinforcement rib 24 is synchronously snapped into the reinforcement groove 15 to further limit and fix the first connecting part and the second connecting part. In addition, the reinforcement groove 15 and the reinforcement rib 24 are both arranged at a certain inclination relative to the set length direction, thereby forming a mutual force sharing, and forming a limiting effect in both the set length direction and the set thickness direction.

[0047] The limiting groove 2 can be set to be open on both sides or on one side in the set thickness direction. After the limiting column 1 is inserted into the limiting groove 2, the first limiting plane 11 abuts against the outer plane of the open side of the limiting groove 2.

[0048] In some other embodiments, referring to Fig.10 and Fig.11 The limiting groove 2 is open on both sides in the set thickness direction, and the limiting column 1 is also provided with a second limiting plane 16 at the protruding end in the set thickness direction. The second limiting plane 16 is opposite to the first limiting plane 11, and the second limiting plane 16 is also offset against the other end of the second connecting portion along the set thickness direction, thereby providing an external shielding for the limiting column 1 and the limiting groove 2 while limiting on both sides in the set thickness direction, thereby improving the aesthetics.

[0049] The second limiting plane 16 and the first limiting plane 11 are arranged parallel to each other, or the second limiting plane 16 is inclined relative to the first limiting plane 11 to form a set angle.

[0050] In some other embodiments, two limiting columns 1 are combined to form a symmetrical connection structure, so that the two first limiting planes 11 are relative to each other, and the parts to be connected with the second connection part can be selectively connected to any one of the limiting columns 1, and the directions of the parts to be connected when connected to the two limiting columns 1 are opposite. Furthermore, the two parts to be connected can be connected to the symmetrical connection structure at the same time.

[0051] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
