[0002] Cabinet structures are commonly found in furniture. The assembled cabinet structure in the prior art includes at least side panels and shelves. Multiple storage spaces are separated by the shelves and side panels. A common assembly method is to open blind holes in the side panels and insert and install connecting pins to support the shelves. In a cabinet structure that divides the storage space into multiple columns, a middle partition is also required. Both sides of the middle partition need to support the shelves. However, considering the length of the connecting pin itself and the thickness of the middle partition, it is impossible to open a through hole in the middle partition and install the connecting pins coaxially on both sides. In the prior art, the connecting pins are often arranged and installed by staggered blind holes on both sides of the middle partition to support the shelves. This makes the supporting positions of the connecting pins on both sides to the shelves not correspond, which increases the difficulty of assembling the cabinet structure and is prone to mis-installation.

[0028] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0029] like Figure 1-3 As shown, an embodiment of the utility model provides a connecting pin 1, which is columnar and used to be inserted into the mounting hole of the vertical plate in the cabinet structure and provide support for the layer plate installed in the cabinet structure; the connecting pin 1 includes a first pin portion 11 and a second pin portion 12.

[0030] The existing cabinet structure is usually formed by assembling multiple vertical boards and layer boards with connecting pins. When the traditional connecting pin is used in the cabinet structure, a part of it is usually inserted into the mounting hole of the vertical board, and the exposed part is used to support the layer board. Figure 4-Figure 7 As shown, in a cabinet structure divided into multiple columns of storage space in the longitudinal direction, the vertical panel includes a side panel 2 and a middle partition panel 3, and the side panel 2 is provided with a plurality of first mounting holes 21 for inserting the connecting pin 1 (from the perspective of process simplification, the first mounting holes 21 use blind holes), and the side panel 2 is assembled in a manner of supporting the layer panel 4 by inserting the connecting pin 1 on one side; second mounting holes 31 are provided on both sides of the middle partition panel 3, that is, connecting pins 1 are installed on both sides of the middle partition panel 3, and a plurality of mounting grooves 41 for embedding the connecting pins 1 are symmetrically provided on both sides of the bottom of the layer panel 4; when using traditional connecting pins, considering the length of the connecting pins themselves, the thickness of the middle partition panel 3 does not support the middle partition panel 3. The corresponding connecting pins 1 on both sides are installed coaxially. Obviously, the second mounting holes 31 cannot be designed as through holes. Therefore, the second mounting holes 31 corresponding to the two sides of the middle partition 3 need to be designed as blind holes, and need to be staggered (that is, the corresponding connecting pins 1 on both sides of the middle partition 3 cannot be coaxial), which will make the mounting grooves 41 on both sides of the bottom of the layer board 4 to adapt to the support of the connecting pins 1 asymmetrical (in fact, the connecting pins 1 on both sides of the middle partition 3 cannot be symmetrically distributed, and the supporting positions of the layer boards on both sides of the middle partition 3 cannot be symmetrical). While increasing the difficulty of users to assemble the cabinet structure, it will also affect the supporting effect of the connecting pins 1 on the layer board 4, and it is easy to cause misinstallation problems.

[0031] Therefore, as the main improvement of the utility model, Figure 1-3As shown, the second pin portion 12 of the connecting pin 1 is formed with a mating surface 121, and the two connecting pins 1 can be assembled facing each other through their respective mating surfaces 121, so that the two second pin portions 12 are assembled facing each other, and the two second pin portions 12 are assembled facing each other to form a variable pin portion 14 with a changeable diameter. Under this improved design, Figure 4-9 As shown, the second mounting hole 31 on the middle partition plate 3 can be designed as a through hole, and the second mounting hole 31 has two ends through which the second pin portion 12 is inserted to insert the mounting connecting pin 1. Due to the opposite assembly of the second pin portions 12 inserted on both sides of the second mounting hole 31, a variable pin portion 14 with a changeable diameter is formed, so that the variable pin portion 14 can adapt to the diameter of the second mounting hole 31. In addition, the diameter of the variable pin portion 14 is adjustable so that it can expand radially in the second mounting hole 31, thereby realizing the variable pin portion 14 and the second mounting hole 31. 1 is fastened together (the change pin portion 14 forms an interference fit with the second mounting hole 31), and on this basis, the first pin portion 11 is embedded in the mounting groove 41 of the layer plate 4 to provide support for the layer plate 4, so that the second mounting hole 31 of the middle partition plate 3 can be designed as a through hole, and the middle partition plate 3 does not need to have a large thickness; and on the first mounting hole 21 of the side plate 2, the connecting pin 1 is installed in a manner that the first pin portion 11 is inserted into the mounting hole 21, and the second pin portion 12 is embedded in the mounting groove 41 of the layer plate 4 to provide support for the layer plate 4.

[0032] In a preferred embodiment, the mating surface 121 is an inclined surface. When the two second pin portions 12 are assembled facing each other, the mating surfaces 121 are in contact and can slide relative to each other, so that the diameter of the variable pin portion 14 can be easily adjusted.

[0033] In addition, in a preferred embodiment, when the two second pin portions 12 of the two connecting pins 1 are assembled and installed in the second mounting hole 31, the two first pin portions 11 are in a state where the axes are parallel (or coaxial), and at this time, the layer plates 4 on both sides of the middle partition plate 3 are parallel (or completely symmetrical), which is beneficial to the beauty of the cabinet structure and is convenient for customers to assemble.

[0034] Figure 4-9 In the cabinet structure embodiment shown, the storage space is divided into multiple columns, so a middle partition 3 is required. Fig.10 As shown, in an embodiment of a cabinet structure having only a single row of storage space, only the side panel 2 needs to be assembled with the layer panel 4 opposite to each other. Obviously, by applying the connecting pin 1 of the utility model, inserting the first pin portion 11 into the first mounting hole 21 of the side panel 2, and embedding the second pin portion 12 into the mounting groove of the layer panel 4 to provide support for the layer panel 4, the assembly requirements of the cabinet structure can still be met.

[0035] like Figure 1-3 As shown, in order to improve the convenience of inserting the first pin portion 11 into the mounting hole, in a preferred embodiment of the present utility model, a chamfer is formed at the end of the first pin portion 11 away from the flange 13 .

[0036] In addition, in a preferred embodiment, a radially protruding flange 13 is formed between the first pin portion 11 and the second pin portion 12. The flange 13 enables the connecting pin 1 to be inserted into the side plate 2 or the middle partition plate 3, and the flange 13 fits the installation surface of the object into which the first pin portion 11 and / or the second pin portion 12 is inserted and installed (in the embodiment of the utility model, the flange 13 fits the surface of the side plate 2 and / or the middle partition plate 3), thereby limiting the deflection of the connecting pin 1 and reducing the shaking of the connecting pin 1.

[0037] The connecting pins provided by the utility model can be assembled in opposite directions to form variable pin sections with variable diameters, so that they can be used alone in blind holes or in combination in through holes, and have good practicality. The cabinet structure provided by the utility model is assembled in opposite directions on the middle partition board using the connecting pins provided by the utility model, so that the supporting positions of the layer boards on both sides of the connecting pins correspond to each other, which is convenient for installation and can reduce the occurrence of wrong installation problems.

[0038] The above-mentioned embodiments only express the implementation methods of the utility model, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
