[0021] FIG. 1 is a perspective view of a tool - free and assemblable cabinet device of the present invention. Referring to FIG. 1, the tool - free and assemblable cabinet device 100 of the present invention includes an upper plate 110A, a bottom plate 110B, two side plates 130, a rear plate 140, and a plurality of assembly members 150. The upper plate 110A has the same structure as the bottom plate 110B. A distance is provided between the upper plate 110A and the bottom plate 110B, and two side plates 130 are provided between the upper plate 110A and the bottom plate 110B. The upper and lower sides of the two side plates 130 are connected to the upper plate 110A and the bottom plate 110B, and a distance is provided between the two side plates 130. The upper plate 110A, the bottom plate 110B, and the two side plates 130 form a rectangular structure. The upper and lower sides of the rear plate 140 are connected to the upper plate 110A and the bottom plate 110B respectively, and the left and right sides of the rear plate 140 are connected to the side plates 130 respectively, forming a rectangular cabinet with an opening MA. The assembly members 150 are provided on the upper plate 110A, the bottom plate 110B, and the side plates 130. The assembly members 150 assemble the upper plate 110A and the side plates 130, and the side plates 130 and the bottom plate 110B together to constitute the tool - free and assemblable cabinet device 100.

[0022] FIG. 2 is a perspective view of the assembly members in region A1 according to FIG. 1. Referring to FIG. 2, the assembly member 150 of the present invention includes a female fastener 152 and a male fastener 154. In one embodiment, the assembly member 150 is punched from an iron plate and formed into a metal fitting assembly member, and is divided into the male fastener 154 and the female fastener 152. The female fastener 152 is a single iron plate, and is provided with a keyhole 1524 and an inclined structure NA in the middle. The male fastener 154 is a rivet screw. The male fastener 154 is engaged in the keyhole 1524, and the male fastener 154 is assembled in the female fastener 152. The inclined structure NA makes the male fastener 154 be fixed more and more tightly during the process of sliding and blocking.

[0023] The female fastener 152 will be described below with reference to FIGS. 2 to 5. FIG. 3 is a perspective view of the female fastener of the present invention. FIG. 4 is a top view of the female fastener of the present invention. FIG. 5 is a side view of the female fastener of the present invention. Referring to FIGS. 2 to 5, the female fastener 152 of the present invention includes a first plate 1522, a keyhole 1524, a second plate 1526, a positioning portion 1528, an inclined structure NA, and two fixing holes PA. The keyhole 1524 penetrates the first plate 1522. The keyhole 1524 is an opening in the first plate 1522. The keyhole 1524 includes a first hole edge region T1 and a second hole edge region T2 in order along the assembly direction LA. Both ends of the keyhole 1524 are the first hole edge region T1 and the second hole edge region T2 respectively. The hole in the first hole edge region T1 is larger than the hole in the second hole edge region T2. The first plate 1522 is connected to the second plate 1526. The positioning portion 1528 projects from the second plate 1526. The positioning portion 1528 is a protruding structure that protrudes from the surface of the second plate 1526. The positioning portion 1528 is adjacent to the first hole edge region T1.

[0024] The first plate 1522 includes a first portion 1522A and a second portion 1522B. The second portion 1522B is connected to the first portion 1522A. The second portion 1522B is provided between the first portion 1522A and the second plate 1526. The second portion 1522B is adjacent to the positioning portion 1528. The first hole edge region T1 of the keyhole 1524 is provided in the second portion 1522B, and the second hole edge region T2 is provided in the first portion 1522A. Also, one fixing hole PA is provided in the first portion 1522A, and the other fixing hole PA is provided in the second plate 1526.

[0025] The second part 1522B is an inclined structure NA. The second part 1522B has a first side P1 and a second side P2 that face each other along the assembly direction LA. The first side P1 is connected to the second plate 1526, and the second side P2 is connected to the first part 1522A. Since the thickness H1 of the first side P1 of the second part 1522B is smaller than the thickness H2 of the second side P2 of the second part 1522B, the surface of the second part 1522B is made non-flat to form the inclined structure NA. It gradually increases from the dimension of the thickness H1 of the first side P1 to the dimension of the thickness H2 of the second side P2 of the second part 1522B and has an inclination angle AG. That is, the thickness of the hole of the keyhole 1524 is not constant, and the thickness of the first hole edge region T1 is smaller than the thickness of the second hole edge region T2.

[0026] Continuing to refer to FIGS. 2 and 6, FIG. 6 is a perspective view of the male fastener of the present invention. The form of the male fastener 154 of the present invention is a rivet screw and includes a rivet part 1542, a screw part 1544, and a connecting part 1546. The connecting part 1546 is connected between the rivet part 1542 and the screw part 1544. The diameter dimension of the connecting part 1546 is smaller than the diameter dimension of the rivet part 1542 and the diameter dimension of the screw part 1544 respectively, and the diameter dimension of the screw part 1544 is larger than the diameter dimension of the rivet part 1542.

[0027] The following describes the assembly process of assembling the male fastener 154 with the female fastener 152 through FIGS. 7 to 12. FIG. 7 is a perspective view of the assembly process of the male and female fasteners of the present invention. FIG. 8 is a side view of the assembly process of the male and female fasteners of the present invention. FIG. 9 is a perspective view of the male fastener of the present invention at the first position of the keyhole of the female fastener. FIG. 10 is a side view of the male fastener of the present invention at the first position of the keyhole of the female fastener. FIG. 11 is a perspective view of the male fastener of the present invention at the second position of the keyhole of the female fastener. FIG. 12 is a top view of the male fastener of the present invention with respect to the female fastener. The first position is the first hole edge region T1 where the male fastener 154 is located, and the second position is the second hole edge region T2 where the male fastener 154 is located. The male fastener 154 is assembled with the female fastener 152. The diameter dimension of the connecting portion 1546 of the present invention is smaller than the dimensions of the first hole edge region T1 and the second hole edge region T2. The dimension of the first hole edge region T1 is larger than the diameter dimension of the rivet portion 1542, but the dimension of the second hole edge region T2 is smaller than the diameter dimension of the rivet portion 1542. The rivet portion 1542 and the connecting portion 1546 connected thereto are respectively passed through the second hole edge region T2. Since the diameter dimension of the screw portion 1544 is larger than the dimensions of the first hole edge region T1 and the second hole edge region T2, the screw portion 1544 does not pass through the keyhole 1524 and is blocked by the first plate 1522.

[0028] In this configuration, as shown in FIG. 9, the male fastener 154 moves along the insertion direction LB, and the rivet portion 1542 and the connecting portion 1546 connected thereto can sequentially pass through the holes in the first hole edge region T1, but the screw portion 1544 is blocked without being able to pass through the first hole edge region T1. Next, the male fastener 154 moves along the assembly direction LA, moving the male fastener 154 from the first hole edge region T1 to the second hole edge region T2. The hole dimension of the first hole edge region T1 is larger than the hole dimension of the second hole edge region T2. The male fastener 154 is gradually moved into the hole of the second hole edge region T2 with a smaller dimension, and the connecting portion 1546 is gradually constrained by the hole region around the second hole edge region T2 in the keyhole 1524, fixing the connecting portion 1546 to the second hole edge region T2. The rivet portion 1542 is located on the first plate 1522. Due to the relationship of the inclined structure NA, the thickness of the first hole edge region T1 is smaller than the thickness of the second hole edge region T2. In the thickness direction, the connecting portion 1546 is also gradually constrained. Due to the inclined structure NA, as shown in FIG. 12, the male fastener 154 can be more and more tightly fixed in the keyhole 1524 of the female fastener 152 during the process of sliding and blocking.

[0029] Also, as shown in FIG. 9, when the male fastener 154 is located in the first hole edge region T1, the periphery on one side of the rivet portion 1542 is supported by the positioning portion 1528 instead of the second plate 1526. Thereby, it can be ensured that the rivet portion 1542 is located above the hole of the keyhole 1524, making it easier to assemble.

[0030] Also, the male fastener 154 can finely adjust the depth. For example, by adjusting the length of the connecting portion 1546, the processing tolerance when the male fastener 154 and the female fastener 152 are combined can be eliminated.

[0031] The following will explain the assembly process of the cabinet device that can be assembled without tools through FIGS. 13 to 21. FIG. 13 is an exploded explanatory view of the cabinet device that can be assembled without tools according to the present invention. The upper plate 110A and the bottom plate 110B of the present invention each include an outer surface 112, an inner surface 114, an assembly groove 116, and four installation groove portions 118. The two opposite surfaces of the upper plate 110A and the bottom plate 110B are the outer surface 112 and the inner surface 114 respectively. As shown in FIG. 13, the inner surface 114 of the upper plate 110A corresponds to the inner surface 114 of the bottom plate 110B. The assembly groove 116 and the four installation groove portions 118 are recessed at different positions on the inner surface 114 respectively. That is, the outer surfaces 112 of the upper plate 110A and the bottom plate 110B are flat surfaces. Among these, two of the installation groove portions 118 are located on one side of the inner surface 114, and the other two installation groove portions 118 are located on the other side of the inner surface 114. And the distance between the two installation groove portions 118 on one side is the same as the distance between the two installation groove portions 118 on the other side. The assembly groove 116 is located outside the four installation groove portions 118. Of course, the positions of the installation groove portions 118 and the assembly groove 116 can be adjusted according to the actual situation. From this, the inner surfaces 114 of the upper plate 110A and the bottom plate 110B of the present invention are each used as an assembly surface, and the outer surfaces 112 of the upper plate 110A and the bottom plate 110B are flat surfaces respectively. On the appearance of the upper plate 110A and the bottom plate 110B, the installation groove portions 118 and the assembly groove 116 are made invisible, thereby maintaining the overall aesthetics and flatness.

[0032] FIG. 14 is a partially enlarged view of the portion where the female fastener in region A2 of FIG. 13 is attached to the bottom plate. FIG. 15 is a partially enlarged exploded view of the assembly process of the female fastener in FIG. 14. The structures of the upper plate 110A and the bottom plate 110B are the same. FIGS. 14 and 15 take the inner surface 114 of the bottom plate 110B as an example respectively. Referring to FIGS. 13 to 15, the female fastener 152 of the present invention is provided in the installation groove portion 118, and the height of the female fastener 152 does not exceed the installation groove portion 118, so that the female fastener 152 can be hidden in the installation groove portion 118.

[0033] Specifically, the installation groove portion 118 includes a support portion 1182 and a receiving groove 1184. The support portion 1182 is a block recessed in the inner surface 114. The height of the support portion 1182 is lower than the height of the inner surface 114. The receiving groove 1184 is a groove recessed in the support portion 1182. The female fastener 152 is provided in the installation groove portion 118. The fixing member 170 is inserted through the fixing hole PA and rotated in the rotation direction R1 to fix the female fastener 152 in the installation groove portion 118. The female fastener 152 is supported in the support portion 1182 of the installation groove portion 118 and communicates with the receiving groove 1184 of the installation groove portion 118 corresponding to the lower part of the keyhole 1524. In this way, an activity space of the receiving groove 1184 is provided below the keyhole 1524.

[0034] Referring to FIG. 13 again, the two side plates 130 of the present invention are respectively provided between the upper plate 110A and the bottom plate 110B. The side plate 130 includes an opposing side plate outer surface 132, a side plate inner surface 134, an insertion groove 136, an upper surface 138A, and a lower surface 138B. The two opposing surfaces of the two side plates 130 are the side plate outer surface 132 and the side plate inner surface 134 respectively. As shown in FIG. 13, the two side plate inner surfaces 134 face each other. The upper surface 138A and the lower surface 138B are respectively connected between the side plate inner surface 134 and the side plate 130. The upper surface 138A corresponds to the inner surface 114 of the upper plate 110A, and the lower surface 138B corresponds to the inner surface 114 of the bottom plate 110B. The insertion groove 136 is recessed in the corresponding side plate inner surface 134. That is, the side plate outer surface 132 of the side plate 130 is a flat surface.

[0035] FIG. 16 is an enlarged partial view of the portion where the male fastener in region A3 of FIG. 13 is attached to the side panel. FIG. 17 is an enlarged partial exploded view of the assembly process of the male fastener in FIG. 16. Referring to FIGS. 13, 16, and 17, the form of the lower surface 138B is the same as that of the upper surface 138A. FIGS. 16 and 17 take the upper surface 138A as an example. The male fastener 154 of the present invention is provided on the upper surface 138A and the lower surface 138B of the side panel 130. The side panel 130 includes screw holes 139, and the screw holes 139 are provided on the upper surface 138A. The screw hole 139 of the present invention is a through hole on the upper surface 138A of the side panel 130, and the number thereof is adjusted according to the number of male fasteners 154. Similarly, the lower surface 138B of the side panel 130 has the same structure as the upper surface 138A and also has screw holes 139. The screw portion 1544 of the present invention rotates in the rotational direction R2 through the screw hole 139 to fix the screw portion 1544 in the screw hole 139, and the rivet portion 1542 and the connecting portion 1546 connected thereto are provided outside the screw hole 139. As can be seen from this, the upper surface 138A and the lower surface 138B of the side panel 130 of the present invention, and the inner surface 134 of the side panel each become an assembly surface. The outer surface 132 of the side panel of the side panel 130 is a flat surface, so that the screw holes 139 and the insertion grooves 136 are not visible on the appearance of the side panel 130, thereby maintaining the overall aesthetics and flatness.

[0036] FIG. 18 is an explanatory view of the assembly process of the tool-free and assemblable cabinet device of the present invention. FIGS. 19 to 21 are explanatory views of the assembly process in which the male fastener of the present invention is assembled with the female fastener in order. For convenience of explanation, FIGS. 19 to 21 each show a partial cross-section of the assembly process of the male fastener 154 and the female fastener 152. Taking the attachment of the side plate 130 to the bottom plate 110B as an example, similarly, it is also applicable when the upper plate 110A is attached to the side plate 130. Referring to FIGS. 13, 18 to 21, the rear plate 140 of the present invention is a flat plate. Both sides of the rear plate 140 are inserted into the insertion grooves 136 of the side plates 130 on the left and right sides respectively, and the rear plate 140 is attached between these two side plates 130. Further, the position of the insertion groove 136 is adjacent to the assembly groove 116. For example, these two side plates 130 are respectively erected on both sides of the bottom plate 110B, or these two side plates 130 are respectively erected under both sides of the upper plate 110A.

[0037] Next, the male fasteners 154 on the side panels 130 are respectively aligned with the female fasteners 152 on the bottom plate 110B. Similarly, the female fasteners 152 on the upper plate 110A are also respectively aligned with the male fasteners 154 on the side panels 130. The upper and lower sides of the rear plate 140 are respectively inserted into the assembly grooves 116 of the upper plate 110A and the bottom plate 110B, and the rear plate 140 is attached between the upper plate 110A and the bottom plate 110B. Along the insertion direction LB, the male fastener 154 is moved into the keyhole 1524 of the female fastener 152. As shown in FIG. 9, the rivet portion 1542 and the connecting portion 1546 connected thereto can be sequentially inserted through the holes in the first hole edge region T1, but the screw portion 1544 is blocked and cannot pass through the first hole edge region T1. At the same time, as shown in FIG. 14 or FIG. 15, the rivet portion 1542 and the connecting portion 1546 can be accommodated in the accommodation groove 1184. Next, as shown in FIG. 21, the male fastener 154 moves along the assembly direction LA. The male fastener 154 moves from the first hole edge region T1 (see FIGS. 9 and 10) to the second hole edge region T2 (see FIGS. 11 and 12), and the connecting portion 1546 is gradually constrained in the hole region around the keyhole 1524. Further, due to the relationship of the inclined structure NA, the male fastener 154 is more and more tightly fixed in the keyhole 1524 of the female fastener 152 during the process of sliding and blocking. Similarly, the upper plate 110A is attached to the side panel 130 based on the above-described method, and a cabinet device 100 that can be assembled without tools as shown in FIG. 1 is configured. The outer surface 112 of the overall appearance of the cabinet device 100 that can be assembled without tools, the outer surface 132 of the side panel, and the rear plate 140 are all flat surfaces, and no holes can be seen from the appearance, achieving an improvement in the flatness of the overall aesthetics.

[0038] In summary, the cabinet device of the present invention that can be assembled does not require the use of tools during assembly, and can be assembled into the cabinet device by assembling the male fasteners with the female fasteners.

[0039] Furthermore, the present invention can more and more tightly fix the male fastener during the process of sliding and blocking by means of the inclined structure.

[0040] In addition, in the female fastener of the present invention, a positioning portion is provided. When the male fastener is disassembled, the periphery on one side of the rivet portion is held by the positioning portion, and in this way, it is ensured that the rivet portion is positioned above the keyhole, facilitating disassembly.

[0041] In addition, the male fastener of the present invention can finely adjust the depth and can eliminate the machining tolerance when assembling the male fastener and the female fastener.

[0042] Although the present invention has been disclosed by the embodiments as described above, this does not limit the present invention. Those skilled in the art can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention is based on what is defined in the claims described later.
