Description

Technical Field

[0001] This utility model belongs to the field of assembly model technology and relates to an assembly model connection structure. Background Technology

[0002] In the assembly of figurines, toys, and other model kits on the market, existing simple connection structures such as universal post-hole plug-in structures and snap-fit ​​structures are used to connect the parts. This allows for the free assembly of various parts of different models and specifications. However, the existing connection structures are limited by factors such as mold precision, part shape and structure, and material hardness. Their structural designs are relatively simple, and the connection strength relies solely on the friction of the part surfaces or the limiting force of small protrusions. When there are errors in processing precision or wear during use, the connection structure is prone to failure, which cannot guarantee the splicing strength of the model parts or the overall stability of the model. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a connection structure for assembled models.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

The connecting plug includes a plug block, and the connecting hole has a through hole for the plug block to engage with the plug block along a predetermined insertion direction. The outer wall of the plug block is provided with a guide groove, and the inner wall of the insertion hole is provided with a guide slider for sliding engagement with the guide groove along the insertion direction. The outer wall of the plug block and the inner wall of the insertion hole are respectively provided with a limiting groove and a limiting block. In the predetermined connection position between the plug block and the insertion hole, the limiting block engages with the limiting groove and provides abutment and limiting in the insertion direction to the plug block and the insertion hole.

[0006] Furthermore, the limiting block has a linear structure, and the linear direction of the limiting block forms a set angle with the insertion direction.

[0007] Furthermore, the two sides of the guide groove and the two sides of the guide slider are configured to engage with inclined surfaces.

[0008] Furthermore, both the outer periphery of the insert block and the inner periphery of the socket are configured as polygonal structures, and the insert block and the socket form an interference fit.

[0009] Furthermore, the inner periphery of the insertion hole is provided with one or more draft surfaces, and the draft surfaces are inclined outward at a set angle to the through direction of the insertion hole.

[0010] Furthermore, the parting line of the connecting hole is distributed along the straight direction of the limiting block, and the draft surfaces are respectively provided on both sides of the insertion hole.

[0011] Furthermore, the connecting plug is also provided with an extension groove, the two sides of which are respectively connected to the limiting groove and the outer wall of the connecting plug.

[0012] Furthermore, there are two of each of the guide groove and the limiting groove, which are respectively located on the opposite outer walls of the insertion block. There are two of each of the guide slider and the limiting block, which are respectively located on the opposite inner walls of the insertion hole.

[0013] In summary, the advantages of this utility model are as follows:

[0026] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0027] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0028] In this embodiment of the invention, all directional indicators (such as up, down, left, right, front, back, horizontal, vertical, etc.) are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0029] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of this utility model may actually be an approximate parallel relationship, and the perpendicular relationship may actually be an approximate perpendicular relationship.

[0030] This utility model provides a connection structure for an assembled model, including a connecting plug and connecting holes. The connecting plug and connecting holes can be respectively set on different model parts. By combining the connecting plug and connecting holes, a fast and stable connection between various model parts can be achieved that can be repeatedly disassembled.

[0031] Any part in the model can be equipped with a connecting plug, a connecting hole, or both, allowing it to be freely combined and connected with one or more other different model parts that are equipped with corresponding matching connecting plugs or connecting holes. The connection status of some embodiments can be referred to... Figure 6 .

[0032] Reference Figures 1 to 3 The connecting hole includes a through-hole 1 formed on the model part, such that the through-hole 1 forms openings on both sides of the model part for the connecting plug to enter along the through direction.

[0033] The inner wall of the socket 1 is provided with a protruding guide slider 11. The guide slider 11 has a set length direction, which is preferably set along the direction in which the connector plug is inserted relative to the connector hole. The guide slider 11 guides and limits the connector plug in the insertion direction and maintains smooth and stable relative movement during the insertion process.

[0034] The inner wall of the socket 1 is further protruding with a limiting block 12. After the connector is inserted into the connector, the limiting block 12 abuts against the connector in the through direction of the socket 1, that is, in the insertion direction of the connector relative to the connector, so as to prevent the connector from being pulled out and detached from the connector with a set damping force.

[0035] Reference Figure 4 and Figure 5 The connecting plug includes a plug 2, which is set at a predetermined position on the model part and integrally formed with the model part. The plug 2 has a columnar structure and is inserted into the socket 1 so that the shape of its outer peripheral wall matches the shape of the inner peripheral wall of the socket 1. Preferably, the plug 2 and the socket 1 form an interference fit to ensure that the connecting plug and the connecting hole are tightly fitted and do not loosen, thus ensuring stability.

[0036] More preferably, both the inner periphery of the socket 1 and the outer periphery of the plug block 2 are configured as polygonal structures, as shown in the reference. Figure 2 As shown, an octagonal structure is adopted. When the two are connected, multiple surfaces abut against each other, making the circumferential force more uniform and the relative circumferential position more stable and reliable when the two are combined.

[0037] The insert 2 has a guide groove 21 along the insertion direction for sliding engagement with the guide slider 11. The guide groove 21 is connected to the end of the insert 2 so that the guide slider 11 can enter smoothly. On both sides perpendicular to the insertion direction, the two sides of the guide groove 21 and the two sides of the guide slider 11 are respectively provided with matching mating surfaces to achieve limiting and relative sliding. Preferably, the mating surfaces are set as inclined surfaces so that the guide slider 11 and the guide groove 21 are both trapezoidal structures when projected in the insertion direction.

[0038] The insert 2 is provided with a limiting groove 22 for engaging the limiting block 12. During the insertion process of the insert 2 and the socket 1, the limiting block 12 first interferes with the surface of the insert 2, and its plastic or plastic material can undergo a certain reversible elastic deformation until the limiting block 12 moves to the position of the limiting groove 22. Then the limiting block 12 returns to its original position and is embedded in the limiting groove 22, forming an abutment with the limiting groove 22, thereby limiting the insertion block 2 and the socket 1 in the insertion direction.

[0039] Preferably, the limiting block 12 has a linear structure, and the linear direction of the limiting block 12 forms a set angle with the insertion direction, so that the limiting block 12 and the limiting groove 22 form a line or surface contact, effectively expanding the contact area between the limiting block 12 and the limiting groove 22, improving the limiting effect of both, and ensuring the connection strength between the connecting plug and the connecting hole. Preferably, its linear direction is perpendicular to the insertion direction.

[0040] More preferably, two sets of guide sliders 11 and limiting blocks 12 are provided in the insertion hole 1 in combination, and are respectively disposed opposite to each other on the inner walls of opposite sides of the insertion hole 1. As a matching, two sets of guide grooves 21 and limiting grooves 22 are provided on the insertion block 2 in combination, and are respectively disposed opposite to each other on the outer walls of opposite sides of the insertion block 2. Preferably, the two guide grooves 21 are connected at the end of the insertion block 2.

[0041] The mold opening direction of connector plugs and connector holes is usually adopted. Figure 3 and Figure 5 The a1 and b1 directions shown are, however, limited by the structural shape of the model part itself and the placement of the connecting plugs or connecting holes on the model part, the mold opening direction may change. In order to adapt the mold opening direction without affecting the smoothness of the insertion and the stability of the limiting of the connecting plugs and connecting holes, in some embodiments, refer to Figure 7 and Figure 8 As shown, one or more draft surfaces 13 are provided at a predetermined position on the inner circumference of the insertion hole 1 of the connecting hole component. The draft surfaces 13 are inclined outward at a predetermined angle to the through direction of the insertion hole 1, so that the mold opening direction ( Figure 8The direction of penetration of the a2 direction and the insertion hole 1 can be adjusted within a certain angle range. As an adaptation, the length direction of the guide slider 11 is also inclined and parallel to the direction of the draft surface 13. Preferably, the mold parting line of the connecting hole is located in the middle of the limiting block 12 and is set along the straight direction of the limiting block 12. Therefore, on both sides of the mold parting line, that is, on both sides of the limiting block 12 in the penetration direction of the insertion hole 1, draft surfaces 13 are respectively provided. The guide slider 11 is divided into two parts with the straight direction of the limiting block 12 as the center. The two parts are set parallel to the draft surfaces 13 on both sides. Furthermore, the guide slider 11 is also set so that its width gradually narrows along the opening direction towards the insertion hole 1, so that at least one side of the inclined surface can cooperate with the corresponding side inclined surface of the guide groove 21 in the insertion direction, and the other side of the inclined surface has a margin with the guide groove 21. While ensuring smooth guidance of the insertion action, it makes the mold opening smoother and more flexible.

[0042] In other embodiments, reference is made to Figure 9 and Figure 10 As shown, an extension groove 23 is provided on one side of the limiting groove 22 of the connecting plug. The extension direction of the extension groove 23 is set opposite to the insertion direction of the connecting plug into the connecting hole, so that the two ends of the extension groove 23 are respectively connected to the limiting groove 22 and the outer wall of the connecting plug. The limiting groove 22 still maintains the limiting effect on the limiting block 12 in the direction, while the mold opening direction of the connecting plug has been flexibly adjusted to Figure 10 The direction shown is b2.

[0043] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort should fall within the protection scope of this utility model.
