DETAILED DESCRIPTION

The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

The present application discloses an invisible connection structure. In some examples, the invisible connection structure disclosed in the present application includes a first connection plate 1 , a second connection plate 2 , an internal threaded member 3 and a threaded connection member 5 .

Please refer to Figure 1. The first connecting plate 1 includes a plurality of first panels 11 and a first supporting plate 12 which are sequentially connected to form a closed figure. The number of the first panels 11 is generally four, and the closed figure is in the shape of a rectangle. Of course, the number of the first panels 11 can also be three or other numbers.

A group of opposite sides of the first supporting plate 12 are fixedly connected to the adjacent first panel 11 , mainly playing a supporting role, which can reduce the weight of the first connecting plate 1 while ensuring the structural strength.

Please refer to Figure 2. The second connecting plate 2 includes a plurality of second panels 21 which are sequentially connected and form a closed figure. The number of the second panels 21 is generally four, and the shape of the closed figure is a rectangle. Of course, the number of the second panels 21 can also be three or other numbers.

A set of opposite sides of the second supporting plate 22 are fixedly connected to the adjacent second panel 21 , mainly playing a supporting role, which can reduce the weight of the second connecting plate 2 while ensuring the structural strength.

The internal threaded member 3 is located inside the first connecting plate 1 and/or inside the second connecting plate 2, and has the following structures:

The first type: the internal thread member 3 includes a short tube 31 arranged on the first panel 11 and a first thread 32 arranged on the inner wall of the short tube 31, please refer to FIG. 3 .

The second type: the internal thread member 3 includes two symmetrically arranged arc-shaped members 33 arranged on the first panel 11 and a second thread 34 arranged on the inner side surface of the arc-shaped member 33, please refer to FIG. 4 .

The difference between the above two structures lies in the short tube 31 and the two symmetrically arranged arc-shaped members 33. Since there is a gap between the two symmetrically arranged arc-shaped members 33, from a functional point of view, both structures can realize the connection function.

A connecting hole 4 is provided on the first panel 11 and/or the second connecting plate 2, see FIG. 5 , one end of the threaded connector 5 passes through the connecting hole 4 and is connected to the internal threaded member 3 to fix the second connecting plate 2 and the first connecting plate 1 together.

It should be noted here that the internal threaded part 3 and the connecting hole 4 provide a connecting function, that is, as long as the internal threaded part 3 and the connecting hole 4 appear at the same time at the connection point, the present application does not limit the two to be only on the first panel 11 or only on the second panel 21.

In some examples, the short tube 31 is integrally formed with an adjacent first support plate 12 , that is, a portion of the short tube 31 is integrated with an adjacent first support plate 12 , so that the structural strength of the short tube 31 can be improved with the help of the first support plate 12 .

In some examples, one of the two arc-shaped members 33 belonging to the same internal thread member 3 is integrated with the adjacent first support plate 12 , so that the structural strength of the arc-shaped member 33 can be improved with the help of the first support plate 12 .

In some examples, please refer to Figures 1 and 6, a first connecting slot 13 and/or a first connecting card 14 are provided on the first connecting plate 1. The first connecting slot 13 or the first connecting card 14 may exist on the first connecting plate 1. Of course, the first connecting slot 13 and the first connecting card 14 may also exist on the first connecting plate 1 at the same time.

The first connection slot 13 and the first connection fixture 14 function to realize the connection between the two first connection plates 1 and the connection between the first connection plate 1 and the second connection plate 2 .

When connecting, just insert the first connecting card 14 into the corresponding first connecting card slot 13. The matching mode of the connection is interference fit to improve the structural strength of the connection. Of course, the structural strength of the connection can also be improved by contacting the inclined surface. The specific method is:

In a direction away from the bottom surface of the first connecting slot 13, the width of the first connecting slot 13 gradually decreases;

In the direction away from the first connecting plate 1 , the width of the first connecting clamp 14 gradually increases.

In this way, when the first connecting card 14 is inserted into the corresponding first connecting card slot 13, when the first connecting card 14 and/or the first connecting card slot 13 receive a pulling force, a force opposite to the pulling force will be generated at the contact surface between the two, preventing the first connecting card 14 and the first connecting card slot 13 from separating.

In some examples, see Fig. 2, the second connecting plate 2 is provided with a second connecting slot 23 and/or a second connecting fixture 24. The functions of the second connecting slot 23 and the second connecting fixture 24 are the same as those of the first connecting slot 13 and the first connecting fixture 14, and are not described in detail here.

The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
