[0040] The structure of the present invention and the technical effects to be achieved will be described below with reference to specific embodiments and accompanying drawings. However, the selected embodiments are only for illustration and explanation and are not intended to limit the scope of the present invention.

[0041] like Figure 1 As shown, the present invention provides an assembled socket-and-spigot connection partition system with a finishing layer in a building interior, comprising a building frame 1 and a plurality of partition wall units 2 located in the building frame 1 .

[0042] like Figure 1 As shown, the building frame 1 includes a building top plate 11, a building floor 12 and a building side plate 13 located between the building top plate 11 and the building floor 12, which together form a rectangular space. Figure 2 、 Figure 2A As shown, the bottom surface of the building top plate 11 is fixed with a top keel 14. The longitudinal section of the top keel 14 is an inverted U-shaped, including a first horizontal plate 141 and a first vertical plate 142 perpendicularly connected to both sides of the first horizontal plate 141. The first horizontal plate 141 is fixedly connected to the building top plate 11 by a first bolt 143. Figure 2 、 Figure 2C As shown, the top surface of the building floor 12 is provided with a ground keel 15, which is opposite to the top keel 14. The ground keel 15 has a U-shaped longitudinal section, including a second horizontal plate 151 and second vertical plates 152 perpendicularly connected to both sides of the second horizontal plate 151. The second horizontal plate 151 is fixedly connected to the building floor 12 by second bolts 153. Figure 3 、 Figure 3AAs shown, a vertical side keel 16 is fixedly provided on the side of the building side panel 13. The cross section of the side keel 16 is U-shaped, including a first side panel 161 and a second side panel 162 perpendicularly connected to the two ends of the first side panel 161. The first side panel 161 is fixedly connected to the building side panel 13.

[0043] like Figure 2 、 Figure 3 As shown, the partition wall unit 2 includes a first decorative plate 21 and a second decorative plate 22 parallel to each other, and the first decorative plate 21 and the second decorative plate 22 are both rectangular. Figures 2A-3C 、 Figure 5 As shown, the back of the first decorative panel 21 is provided with a plurality of first vertical keels 211, and adjacent first vertical keels 211 are connected by a plurality of first transverse keels 212. The top of each first vertical keel 211 is inserted into a slot in a first vertical plate 142 of the top keel 14, and the bottom is inserted into a slot in a second vertical plate 152 on the same side of the floor keel 15. The first vertical keel 211 has an L-shaped cross-section and includes a first keel plate 2111 and a second keel plate 2112 connected perpendicularly to each other. The first keel plate 2111 is fixedly connected to the first decorative panel 21 by screws. The side of the second keel plate 2112 is provided with a plurality of U-shaped cross-sectional clamps 3. The middle portion of each clamp 3 has corresponding through-holes with the second keel plate 2112, and the through-holes are provided with horizontal pull rods 4. One end of the pull rod 4 is located to the side of the clamp 3 and is threadedly connected to a positioning nut 41, whose cross-section is larger than the through-hole. The other end of the pull rod 4 is located to the side of the second keel plate 2112 and is connected to a fixing head 42. The fixing head 42 has a first inclined surface 421 on the end facing the second keel plate 2112. An adjustment head 43 is sleeved on the pull rod 4 between the fixing head 42 and the second keel plate 2112. One end of the adjustment head 43 is fixedly connected to the second keel plate 2112, and the other end has a second inclined surface 431 corresponding to the first inclined surface 421. This allows the fixing head 42 to rotate, driving the pull rod 4 horizontally, thereby opening or tightening the opening of the clamp 3. Specifically, the angle between the first inclined surface 421 and the axis of the pull rod 4 is smaller than the angle between the second inclined surface 431 and the axis of the pull rod 4. To facilitate the resetting of the opening of the clamp 3, a spring 44 is sleeved on the portion of the pull rod 4 located within the clamp 3. The fixing head 42 is provided with a horizontal first rotating plate 45 on one side facing the first keel plate 2111, and a horizontal first long hole 451 is provided at the end of the first rotating plate 45. Figure 4 、 Figures 4A-4D As shown, and reference Figure 2B 、 Figure 3BA vertical first transmission rod 5 is provided on the inner side of the first keel plate 2111. The first transmission rod 5 is provided with a plurality of horizontal first pins 51, each of which is located in a corresponding first slot 451. A horizontal first hooking rod 213 is provided on the top of the second keel plate 2112. The first hooking rod 213 is connected to the top end of the first transmission rod 5 via a first tension spring 214.

[0044] like Figure 4 、 Figures 4A-4C As shown, and reference Figure 2C The floor keel 15 has a horizontal rotation shaft 6 installed inside the second vertical plate 152 corresponding to the bottom of the first vertical keel 211. This rotation shaft 6 is hinged to the middle of the L-shaped second rotating plate 61. One end of the second rotating plate 61 is hinged to the bottom of the first transmission rod 5, and the other end has a vertical second slot 62. A horizontal second transmission rod 7 (passing through the bottom of the second keel plate 2112) is installed inside the second vertical plate 152 corresponding to the bottom of the first vertical keel 211. A second pin 71 is installed on the second transmission rod 7 corresponding to each second slot 62, and the second pin 71 is located in the corresponding second slot 62. An L-shaped angle plate 8 is fixed to the second horizontal plate 151 of the floor keel 15. A horizontal second hooking rod 9 is installed inside the second vertical plate 152 of the floor keel 15 corresponding to the bottom of the first vertical keel 211. The angle plate 8 and the second hooking rod 9 correspond to the bottom ends of the partition wall unit 2, respectively. One end of the second transmission rod 7 is connected to the second hooking rod 9 via a second tension spring 91. The other end passes through the angle plate 8 and is threadedly connected to a control nut 81. The control nut 81 abuts against the side of the angle plate 8 away from the second tension spring 91. To facilitate rotation of the control nut 81, a rectangular operating opening 154 is provided on the second vertical plate 152 of the floor keel 15 at a position corresponding to the angle plate 8.

[0045] The operation process of the transmission system of the present invention is as follows: the horizontal displacement of the second transmission rod 7 can be adjusted by rotating the control nut 81, and then the second rotating plate 61 is driven to rotate around the rotating shaft 6 through the second pin 71. The rotation of the second rotating plate 61 will drive the vertical displacement of the first transmission rod 5, and then the first rotating plate 45 is driven to rotate through the first pin 51. When the first rotating plate 45 rotates, the fixed head 42 and the adjustment head 43 at the end of the pull rod 4 rotate relative to each other. Since the contact surface between the two is an inclined surface, the pull rod 4 will produce horizontal displacement, tightening or loosening the opening of the clamp 3. In order to limit the horizontal displacement of the first pin 51 (because the second rotating plate 62 rotates, it will produce a small horizontal displacement of the first transmission rod 5, but it is mainly vertical) and prevent it from loosening from the first rotating plate 45, a vertical limit plate 215 is provided on the inner side of the first keel plate 2111 at the position corresponding to the first pin 51.

[0046] like Figures 2A-3C 、 Figure 5As shown, the back of the second trim panel 22 is provided with several second vertical ribs 221, and adjacent second vertical ribs 221 are connected by several second transverse ribs 222. The top of each second vertical rib 221 is inserted into a slot in the other first vertical plate 142 of the top rib 14, and the bottom is inserted into a slot in a second vertical plate 152 on the same side of the floor rib 15. The second vertical rib 221 has an L-shaped cross-section and comprises a third rib plate 2211 and a fourth rib plate 2212 connected perpendicularly to each other. The third rib plate 2211 is fixed to the second trim panel 22 via screws. The fourth rib plate 2212 is flanked by several horizontal inserts 23, each corresponding to an opening in a fixture 3 and capable of being inserted into each fixture 3. To facilitate insertion of the inserts 23, the fixture 3 is provided with outwardly extending guide plates 31 at each end of the inserts. The two guide plates 31 are shaped like a figure eight, forming a trumpet-shaped shape.

[0047] like Figure 5 As shown, the plug plate 23 and the clamp 3 connect the first vertical keel 211 and the second vertical keel 221 together. In order to control the distance between the first decorative panel 21 and the second decorative panel 22, that is, the thickness of the partition wall unit 2, the plug plate 23 is provided with a horizontal third long hole 231, and a width adjustment bolt 24 is provided in the third long hole 231. The plug plate 23 is connected to the fourth keel plate 2212 through the width adjustment bolt 24. By adjusting the position of the width adjustment bolt 24 in the third long hole 231, the wall thickness can be conveniently adjusted.

[0048] Specifically, if Figure 6 、 Figure 7 As shown, the two second vertical plates 152 of the ground keel 15 are respectively provided with keel slots 155 corresponding to the first vertical keel 211 and the second vertical keel 221. The keel slots 155 have the same structure and are all U-shaped, so that the first keel plate 2111 of the first vertical keel 211 and the third keel plate 2211 of the second vertical keel 221 are located in the keel slots 155, and an L-shaped groove plate 156 extending inward is provided on one side of the keel slot 155. The end of the groove plate 156 has a gap with the keel slot 155, so that the second keel plate 2112 of the first vertical keel 211 and the fourth keel plate 2212 of the second vertical keel 221 are located in the gap. At the same time, the outer side of the groove plate 156 abuts against the inner side of the first keel plate 2111 and the third keel plate 2211. Figure 2C As shown, a skirting board 157 is provided on the outside of the ground keel 15 to shield the ground keel 15 and the various components inside it.

[0049] like Figure 3C 、 Figure 5As shown, in order to facilitate installation and improve installation accuracy, and improve the flatness of the overall installation surface of the first decorative panel 21 and the second decorative panel 22, the cross-section of the connecting portion of the adjacent first decorative panel 21 and the adjacent second decorative panel 22 is stepped, and they are locked together and positioned accurately. Figure 3A 、 Figure 4A 、 Figure 4D As shown, the second side plate 162 of the side keel 16 is provided with a rectangular pin hole 163, and the sides of the first vertical keel 211 and the second vertical keel 221 close to the side keel 16 are provided with pin plates 164 corresponding to each pin hole, so that each pin plate 164 is inserted into the corresponding pin hole 163.

[0050] The present invention completes the production of the partition wall unit in the factory, including the first decorative panel 21, the first horizontal keel 212, the first vertical keel 211 and the accompanying clamp 3, the first transmission rod 5, the second transmission rod 7, etc., as well as the second decorative panel 22, the second horizontal keel 222, the second vertical keel 221 and the accompanying insert plate 23, forming the two parts of a unit. After being transported to the site, the top keel 14, the floor keel 15, and the side keel 16 are installed. The two parts of the partition wall unit 2 are connected by a simple socket-and-socket connection. The control nut 81 is rotated through the operating port 154, and then the pull rod 4 is used to clamp the clamp 3 to the internal insert plate 23 through the second transmission rod 7 and the first transmission rod 5, firmly fixing it, and the installation is completed. During disassembly, the clamps 3 at various points can be uniformly loosened through the second transmission rod 7 at the lower skirting board 157, which is convenient to operate and can be reused.

[0051] The present invention is defined by the claims, but those skilled in the art may make various obvious changes or modifications based on the claims, all of which are within the spirit and scope of the present invention.
