Detailed ways

The purpose of this embodiment is to provide an assembly structure in which the assembly unit is connected and disassembled by means of a pin-mounted structure, and after the assembly is completed, it cannot be removed under natural conditions, and has high reliability. In addition, after the assembly is completed, the connection at a certain location fails, and the strength of the overall structure is not affected. Moreover, the assembling structure of the assembling structure is simple, no additional connecting parts are required, and the cost is low.

Hereinafter, embodiments will be described with reference to the drawings. Furthermore, the embodiments shown below do not limit the invention as set forth in the claims. Further, the entire contents of the configurations shown in the following embodiments are not necessarily limited to the solutions of the invention described in the claims.

Referring to FIG. 1 to FIG. 9 , an assembly structure provided by this embodiment includes a plurality of first assembling units 11 . The first assembling unit 11 may be specifically a plate shape or a block structure. Each of the first assembling units 11 includes a main body portion 12 and a connecting portion 13.

The outline shape of the main body portion 12 is a 6n-sided shape, wherein n is a positive integer, for example, n may be 1, and when n is 1, the outline shape of the main body portion 12 is a hexagon, and when n is 2, The outline shape of the main body portion 12 is a dodecagonal shape, and when n is 3, the outline shape of the main body portion 12 is an octagonal shape or the like.

A connecting portion 13 is disposed on the side 16 of each main body portion 12. The connecting portion 13 and the main body portion 12 are of a unitary structure, for example, may be integrally connected by injection molding or welding.

The connecting portion 13 on each side 16 of the main body portion 12 of the first assembling unit 11 can be connected to the adjacent first assembling units 11 by a pin mounting structure, for example, when the main body portion 12 of the first assembling unit 11 is a positive six In the case of a side shape, the connecting portion 13 on the six sides thereof can be connected to the six other first assembling units 11 through the pinning structure.

The pin mounting structure between any two first assembling units 11 includes a first pin hole 14 provided on the connecting portion 13 of one of the first assembling units 11, and a connecting portion 13 provided at the other first assembling unit 11. A second pin hole 15 which is upper and which is opposite to the first pin hole 14 and a pin 17 which can be inserted into the first pin hole 14 and the second pin hole 15 at the same time.

When the axial direction of the first pin hole 14 and the second pin hole 15 is opposite to the direction in which the side 16 is located, that is, the pin 17 connects the first pin hole 14 and the second pin hole 15 in series, the pin 17 is along The direction in which the side 16 is located is inserted into the first pin hole 14 and the second pin hole 15.

In the present embodiment, the first pin hole 14 and the second pin hole 15 may be holes formed by injection molding directly on the connecting portion 13, or holes machined by a tool.

It should be noted that when any two first assembling units 11 are assembled together, they are connected by a pin-fit structure, specifically, the first pin hole 14 and the second pin hole 15 of the two first product units 11 are assembled. After that, the pin 17 is pinned into the first pin hole 14 and the second pin hole 15.

In this way, any one of the 6n sides of the 6n edge shape is connected to the other assembling units in the periphery, and since the pinning direction of the pin 17 is the same as the extending direction of the side 16 where it is located, when the connection is completed Thereafter, the pinned structures in which the axial directions intersect at one point form a mutual constraint, that is, the axial displacement of the pinned structure is restricted. Thus, under natural conditions, the pinned structure does not unravel due to its limited axial freedom. Moreover, when one of the pin-type structural connections fails, the overall structural strength is not affected.

For example, when the adjacent three pin-on structures are connected, the axial directions of the three pin-fitting structures intersect at the same point, and the axial separation of the first pin hole 14 and the second pin hole 15 of one of the pin-packed structures Will be constrained by the other two pin-loaded structures, so that the three pin-loaded structures will not slip under the constraint.

In this way, after each pin-loading structure is assembled, it will be restrained by the other two pin-loading structures. Under natural conditions, the pin-loading structure will not be untied. Moreover, when one of the pinned structure connections fails, the other two pinned structures are still constrained to each other. The damage of the partial first splicing unit 11 does not affect the constraint between the overall pinned structures, and thus does not affect the overall structural strength.

In addition, since the main body portion 12 of the first assembling unit 11 provided by the embodiment is a curved structure or a bent structure, the curved structure may be a curved plate-like structure, and the bent structure may be formed by bending a flat structure. structure.

The gap between the two enters into the two second pin holes 15, and then pushes the elastic support member 21, and under the force of the elastic support member 21, the first pin portion 18 and the second pin portion 19 respectively point to two second The pin hole 15 is displaced deep until the first pin hole 14 and the second pin hole 15 are pinned together. The elastic support member 21 is supported between the first pin portion 18 and the second pin portion 19 while preventing the first pin portion 18 and the second pin portion 19 from coming close to each other, resulting in the first pin hole 14 and the second pin hole 15 The problem of connection failure in the natural state.

When disassembly is required, the elastic support member 21 is pulled outward by the position of the gap between the two second pin holes 15, and the elastic support member 21 can respectively have the first pin portion 18 and the second pin portion 19 at both ends thereof. The two second pin holes 15 are pulled out, thus completing the disassembly.
