Abstract
Description
Technical Field
[0001] This utility model relates to a connector structure, specifically a modular cabinet assembly connector structure, belonging to the field of cabinet assembly technology. Background Technology
[0002] Most metal cabinets currently in use are constructed from multiple independent metal connectors. These connectors are joined together by welding and bolting to form a frame, which is then filled with panels or glass.
[0003] The corner assembly structure of an aluminum cabinet disclosed in Chinese Patent Application Publication CN217582763U involves the interlocking of a first connector, a second connector, and a third connector. The first and second connectors serve as internal support components, providing good fastening and stability after installation and preventing loosening. Assembly slots facilitate engagement with the assembly blocks on the first connectors, making installation convenient. The first insertion port on the second connector allows for the fitting of the first connector, and the first threaded through hole facilitates the installation of the first screw. The second threaded through hole facilitates the installation and fastening of the second connector with the second screw. The second insertion port facilitates the connection between the third connector and the second connector. A glass slot accommodates glass or sheet metal. The third screw is installed using the third threaded through hole and the threaded blind hole. A weight reduction port reduces the weight of the first connector.
[0004] In the above patented solutions, the first and second connecting parts can be used as internal support parts, which have good fastening effect and strong stability after installation and can prevent loosening. However, the various connecting parts of the device need to be connected by multiple bolts when installed, and repeated tightening is required during disassembly and installation, which makes the connection of the steel structure more complicated.
[0005] Therefore, a modular cabinet assembly connector structure is proposed here. Utility Model Content
[0006] This utility model proposes a modular cabinet assembly connector structure, which enables quick and convenient assembly and disassembly of the first connector, the second connector, and the third connector, thereby improving assembly and disassembly efficiency.
[0007] This utility model is achieved through the following technical solution: a modular cabinet assembly connector structure, including a first connector, a second connector and a third connector, wherein a first insert and a second insert are fixed on both sides of the first connector near the third connector and the second connector, and the first insert and the second insert are respectively inserted into the third connector and the second connector, and the first connector is provided with an installation component.
[0008] The mounting assembly includes a second through groove formed within a first connector. A bidirectional threaded rod is rotatably connected to the inner wall of the second through groove, and one end of the bidirectional threaded rod passes through the first connector. A rotating block is fixed to the end of the bidirectional threaded rod passing through the first connector. Two L-shaped plates are threadedly connected to the outer surface of the bidirectional threaded rod inside the second through groove, and the outer surface of the L-shaped plates slides in contact with the inner wall of the second through groove. Two sets of mounting rods are fixed to the sides of the two L-shaped plates that are far apart from each other.
[0009] Furthermore, the third connector and the second connector are respectively provided with a second slot and a first slot on the side near the first connector, and the second slot and the mounting slot are respectively inserted into the first plug and the second plug.
[0010] Furthermore, a mounting groove is provided on the right side of the second connector.
[0011] Furthermore, a sliding rod is fixed to the inner wall of the second through groove, and the outer surface of the sliding rod is slidably connected to the inner wall of the hole on the L-shaped plate.
[0012] Furthermore, the first connector has first through slots on both sides near the second and third connectors, and the outer side of the L-shaped plate is located inside the first through slot.
[0013] Furthermore, a set of mounting holes are provided on both the front and rear sides of the third connector and the second connector, and the mounting rod is inserted into the mounting holes.
[0014] Furthermore, the first insert and the second insert are respectively provided with a first moving groove and a second moving groove on the side near the first connector, and both ends of the L-shaped plate are located in the first moving groove and the second moving groove.
[0015] This utility model provides a modular cabinet assembly connector structure, which has the following beneficial effects:
[0016] 1. The modular cabinet assembly connector structure involves inserting the first and second slots on the second and third connectors into the first and second insert blocks on the first connector, respectively. Rotating the rotating block drives the bidirectional threaded rod to rotate. This rotation causes the two ends of the two L-shaped plates to move away from each other within the first and second moving slots on the first and second insert blocks, respectively. The movement of the L-shaped plates causes multiple sets of mounting rods to move out of the first and second moving slots and into the mounting holes on the third and second connectors, thus quickly and conveniently connecting the first, second, and third connectors. Reverse rotation of the rotating block drives the bidirectional threaded rod to separate them, improving assembly and disassembly efficiency. Finally, the panels or glass can be installed in the mounting slot on the second connector. Attached Figure Description

[0029] The second connector 3 has a mounting groove 301 on its right side.
[0030] Please refer to this carefully. Figure 2 , Figure 3 and Figure 4 The mounting assembly 2 includes a second through groove 201 opened in the first connector 1. A bidirectional threaded rod 202 is rotatably connected to the inner side wall of the second through groove 201, and one end of the bidirectional threaded rod 202 passes through the first connector 1. A rotating block 207 is fixed to the end of the bidirectional threaded rod 202 passing through the first connector 1. Two L-shaped plates 203 are threadedly connected to the outer surface of the bidirectional threaded rod 202 inside the second through groove 201, and the outer surface of the L-shaped plates 203 slides in contact with the inner wall of the second through groove 201. Two sets of mounting rods 204 are fixed to the side of the two L-shaped plates 203 that are far apart from each other.
[0031] A slide rod 206 is fixed to the inner wall of the second through groove 201, and the outer surface of the slide rod 206 is slidably connected to the inner wall of the hole on the L-shaped plate 203.
[0032] The first connector 1 has a first through groove 103 on both sides near the second connector 3 and the third connector 4, and the outer side of the L-shaped plate 203 is located inside the first through groove 103.
[0033] The third connector 4 and the second connector 3 each have a set of mounting holes 205 on their front and rear sides, and the mounting rod 204 is inserted into the mounting holes 205.
[0034] The first insert 101 and the second insert 102 are respectively provided with a first moving groove 1011 and a second moving groove 1021 on the side near the first connector 1, and both ends of the L-shaped plate 203 are located in the first moving groove 1011 and the second moving groove 1021.
