[0034] The technical scheme in the utility model embodiment will be described clearly and completely below in combination with the drawings of the utility model embodiment. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0035] The embodiments of the utility model will be described below according to the overall structure.

[0036] The utility model provides a kind of combined cabinet connecting fastener, to solve the problems of existing combined cabinet connecting mode in stability, assembly efficiency and aesthetic property etc., its core innovation lies in the unique fastener body design and the ingenious connecting mode with longitudinal pipe frame 1, horizontal pipe frame 10.

[0037] Combined cabinet connecting fastener, as shown in Figure 1 Figure 5 This combined cabinet connecting fastener is mainly composed of fastener body, longitudinal pipe frame 1 and horizontal pipe frame 10, and the fastener body plays a key connecting role, which includes important components such as butt joint frame 2, connecting block 3 and butt joint groove 4.

[0038] Among them, two groups of connecting blocks 3 are symmetrically installed at the end of the butt joint frame 2, the top of the connecting block 3 protrudes from the top surface of the butt joint frame 2 and its length is greater than that of the butt joint groove 4. During installation, first tilt the butt joint frame 2 by 30°, and then insert the connecting block 3 into the butt joint groove 4 on the outer wall of the longitudinal pipe frame 1. This inclined insertion method utilizes the shape characteristics of the connecting block 3 and the butt joint groove 4, preliminarily realizes the rapid positioning and connection of the fastener body and the longitudinal pipe frame 1, is simple to operate and does not require additional auxiliary tools, thereby improving the assembly efficiency. Then rotate the butt joint frame 2 to a perpendicular state with the longitudinal pipe frame 1. At this time, the inner wall of the connecting block 3 is in close contact with the inner wall of the longitudinal pipe frame 1, and the outer wall of the butt joint frame 2 is in close contact with the outer wall of the longitudinal pipe frame 1, so that the horizontal position of the butt joint frame 2 is preliminarily fixed.

[0039] In the present embodiment, a positioning plate 5 is slidably installed in the butt joint frame 2. The cross section of the positioning plate 5 is designed in a T shape. A positioning groove 6 corresponding to the positioning plate 5 is formed on the outer wall of the butt joint frame 2. Meanwhile, a through hole is formed in the positioning plate 5, and a screw 71 is slidably installed in the through hole. A threaded hole 7 corresponding to the screw 71 is formed on the outer wall of the longitudinal pipe frame 1. During assembly, the screw 71 is inserted through the through hole of the positioning plate 5 and screwed into the threaded hole 7 of the longitudinal pipe frame 1. As the screw 71 is tightened, the positioning plate 5 slides in the positioning groove 6 of the butt joint frame 2 and tightly fits. Through the cooperation of the positioning plate 5, the screw 71, the threaded hole 7 and the positioning groove 6, the connection between the butt joint frame 2 and the longitudinal pipe frame 1 is further fixed in the longitudinal direction, the stability of the connection is increased, the displacement of the butt joint frame 2 in the longitudinal direction is prevented, and the stability of the cabinet structure during long-term use is ensured.

[0040] In the present embodiment, the horizontal pipe frame 10 and the butt joint frame 2 are connected in a sliding manner.

[0041] ​The horizontal pipe frame 10 is in a hollow design and is provided with an opening at the end, and a through hole corresponding to the screw 71 is formed in the bottom of the horizontal pipe frame 10, and a corresponding threaded hole 7 is formed in the bottom of the butt joint frame 2. During the connecting process, the horizontal pipe frame 10 is slidably connected with the butt joint frame 2 through the hollow position at the end of the horizontal pipe frame 10. Since the butt joint frame 2 is in a U-shaped design and the distance between the top and the bottom of the butt joint frame 2 is less than the distance between the top and the bottom of the hollow position in the horizontal pipe frame 10, the horizontal pipe frame 10 can be easily and stably connected with the butt joint frame 2. The sliding connection mode makes the assembly process of the horizontal pipe frame 10 and the butt joint frame 2 simple and fast, and the complex alignment operation is not needed, so that the assembly efficiency is improved, and the position of the horizontal pipe frame 10 can be adjusted according to actual needs during the installation process. When the end of the horizontal pipe frame 10 is attached to the outer wall of the vertical pipe frame 1, the threaded hole 7 in the bottom of the horizontal pipe frame 10 corresponds to the threaded hole 7 in the bottom of the butt joint frame 2. At this time, the screw 71 is screwed through the threaded holes 7 of the horizontal pipe frame 10 and the butt joint frame 2 and is tightened, so that the connection between the horizontal pipe frame 10 and the butt joint frame 2 is completed, and the stable connection between the vertical pipe frame 1 and the horizontal pipe frame 10 is realized.

[0042] For example, the pressing plate 9 is slidably installed on the top of the butt joint frame 2, and a mounting groove 8 corresponding to the pressing plate 9 is formed in the top of the butt joint frame 2. The mounting groove 8 is open at the top and has the same depth as the thickness of the pressing plate 9 and is greater than the gap between the end of the butt joint frame 2 and the inner wall of the horizontal pipe frame 10. During the final stage of the installation process, when the screw 71 is used to fix the horizontal pipe frame 10 and the butt joint frame 2, as the end of the screw 71 gradually extends into the butt joint frame 2, the top end of the screw 71 will be attached to the bottom of the pressing plate 9. At this time, the screw 71 is not tightened and will continue to push the pressing plate 9 upward, so that the pressing plate 9 moves upward under the limitation of the mounting groove 8. The mounting groove 8 provides guidance and limiting for the sliding of the pressing plate 9, so that the pressing plate 9 can only move in a specified direction and range. Until the pressing plate 9 is attached to the inner wall of the horizontal pipe frame 10 under the pushing force of the screw 71, at this time, the pressing plate 9 cooperates with the screw 71 to further fix the connection between the horizontal pipe frame 10 and the butt joint frame 2, so that the tightness of the connection between the horizontal pipe frame 10 and the butt joint frame 2 is increased, the upward displacement of the horizontal pipe frame 10 in the use process is prevented, the stability of the entire connection structure is further enhanced, and since the thickness of the pressing plate 9 is greater than the gap between the butt joint frame 2 and the horizontal pipe frame 10, the two sides of the pressing plate 9 are still located in the mounting groove 8, so that the position of the pressing plate 9 is fixed, which makes the pressing plate 9 play an auxiliary fixing role while preventing the pressing plate 9 from deviating or falling off, and the stability of the connection is continuously and effectively maintained.

[0043] In summary, through the careful design and cooperative matching of various components, the combination cabinet body is efficiently, stably and beautifully connected, and many problems existing in the prior art are effectively solved.

[0044] The working principle of the present invention is as follows: when using the fastener, first tilt the docking frame 2 by 30 degrees, then insert the connecting block 3 at its end into the docking groove 4, and then rotate the docking frame 2 to a state perpendicular to the longitudinal tube frame 1. At this time, the inner wall of the connecting block 3 will be in contact with the inner wall of the longitudinal tube frame 1, and the outer wall of the docking frame 2 will be in contact with the outer wall of the longitudinal tube frame 1, so that the position of the docking frame 2 is initially fixed. Subsequently, screw 71;

[0045] Next, place the positioning plate 5 into the docking groove 4, and then slide the cross tube frame 10 into the docking frame 2 through the hollowed-out position at its end. Because the distance between the upper and lower ends of the docking frame 2 is smaller than the width between the hollowed-out positions at the ends of the cross tube frame 10, the cross tube frame 10 can be easily slid into the docking frame 2.

[0046] Until the end of the transverse tube rack 10 is in contact with the outer wall of the longitudinal tube rack 1, the threaded hole 7 at the bottom of the transverse tube rack 10 will correspond to the threaded hole 7 at the bottom of the docking frame 2. Then, the connection between the transverse tube rack 10 and the docking frame 2 is fixed by screws 71, completing the connection between the longitudinal tube rack 1 and the transverse tube rack 10.

[0047] When the bolt 71 is tightened, the top of the bolt 71 will contact with the bottom of the pressure plate 9, and the pressure plate 9 will start to move upward under the restriction of the installation groove 8, until the pressure plate 9 contacts the inner wall of the cross tube frame 10 under the action of the thrust given by the bolt 71, and the pressure plate 9 will cooperate with the screw 71 to further fix the connection between the cross tube frame 10 and the docking frame 2. Moreover, since the thickness of the pressure plate 9 is greater than the gap between the docking frame 2 and the cross tube frame 10, it is ensured that after the pressure plate 9 further fixes the cross tube frame 10 and the docking frame 2, both sides of the pressure plate 9 are still located in the installation groove 8, thereby ensuring the fixity of the position of the pressure plate 9.

[0048] During subsequent use, the lateral position of the docking frame 2 is fixed by the action of the connecting block 3 and the docking groove 4. At the same time, the longitudinal position of the docking frame 2 and the longitudinal tube frame 1 is fixed by the action of the screw 71, the positioning plate 5 and the threaded hole 7. Since the lateral position between the docking frame 2 and the connecting block 3 is fixed by the corresponding threaded hole 7 and the screw 71, and the positioning plate 5 is further fixed by the screw 71, the connection between the docking frame 2 and the transverse tube frame 10 is further fixed, thereby fixing the connection between the longitudinal tube frame 1 and the transverse tube frame 10, thereby ensuring stability and fixity in subsequent use.

[0049] Although the embodiments of the utility model have been shown and described, the specific embodiments are only the explanation of the utility model, and are not the limitation of the utility model, and the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable way, and the person skilled in the art can make the modification, replacement and change of the embodiments without the creative contribution after reading the specification without departing from the principles and the purpose of the utility model, but as long as in the claim range of the utility model, it is protected by the patent law.
