Description

Technical Field

[0001] The utility model relates to the technical field of electrical cabinets, and particularly relates to a spliced cabinet with efficient assembly. Background Art

[0002] Nowadays, in the fields of industrial automation, IT data centers, communication base stations, etc., as a carrier for installing key electronic devices such as servers, switches, and power equipment, the structural design of the frame cabinet directly affects the operation stability, maintenance convenience, and usage cost of the equipment. At present, due to characteristics such as high strength and light weight, the spliced cabinet has become one of the mainstream products widely used in the industry.

[0003] Traditional spliced cabinets usually use three-way connectors to assemble the columns, crossbeams, and longitudinal beams at the eight top corners. This overall three-way structure not only consumes a large amount of raw materials, significantly increasing production costs, but also requires multiple processes such as cutting, stamping, and welding during the manufacturing process, resulting in high processing difficulty and low production efficiency. In addition, during the assembly process of the complex three-way structure, the technical requirements for installers are relatively high, with high installation difficulty and long time consumption, increasing the time cost.

[0004] Some existing improvement solutions also have limitations. For example, Chinese Utility Model Patent Application CN202122530908 discloses a front-back spliced frame cabinet, specifically a right-angle rivet hole and a tenon of the socket connection (tight fit), a counterbore and a countersunk head bolt connection (tight fit). It uses a non-circular tenon and mortise design to prevent the assembled beam from rotating, but the processing accuracy requirements for the non-circular structure are high, resulting in complex die manufacturing and production processes, significantly increasing production costs. Moreover, the alignment of the special-shaped mortise holes is difficult, prolonging the installation time. Chinese Utility Model Patent Application CN202320509464.X discloses a spliced cabinet with mortise and tenon connections, specifically a tenon of the socket inserted into a mortise of a right-angle vertical foot to form a mortise and tenon structure, and a screw is screwed into a threaded hole of the tenon and passes through a countersunk head hole and a positioning hole on the side of the mortise to lock this mortise and tenon structure; it attempts to solve the problem by fixing the circular tenon with a transverse screw. The transverse screw cannot tighten the tenon along the axis, resulting in loose connection and poor connection reliability. Moreover, only a line contact is formed between the longitudinal beam and the connector, affecting the overall sealing performance of the cabinet. With the continuous improvement of market requirements for cabinet products in terms of storage and transportation convenience, production and processing efficiency, and installation accuracy, there is an urgent need for a nine-fold profile spliced cabinet that can not only reduce costs and simplify processes but also ensure structural strength and installation convenience. Content of the Utility Model

[0005] Objective of the utility model: In order to overcome the defects of the prior art, the utility model provides a spliced cabinet with efficient assembly, and solves the core problems of high processing cost, low assembly efficiency, and insufficient connection reliability in the prior art.

[0006] Technical solution of the utility model: It includes a first frame bar, a second frame bar, a third frame bar, a fixing mechanism, a right-angle connector and a third pin separated from the right-angle connector. Among them, each frame bar has a socket hole. The right-angle connector includes a first pin and a second pin that are integrally connected perpendicular to each other. The first pin and the second pin are respectively inserted into the socket holes of the first frame bar and the second frame bar, and the adjacent end faces of the first frame bar and the second frame bar form a right-angle space after insertion; a connecting neck is formed at the corner position of the first pin and the second pin, and one side of the connecting neck has a mating surface for docking the third insertion. The right-angle space extends to the outside of the mating surface and the extended part forms a pair of right-angle abutting surfaces; the third pin is inserted into the socket hole of the third frame bar, and the third pin is fixedly connected to the connecting neck through the fixing mechanism; the end face of the third frame bar is in contact with the mating surface, and a pair of right-angle side faces are provided on the lateral right-angle side of its end face. The right-angle side faces are fitted into the right-angle space and are tightly abutted against the right-angle abutting surfaces.

[0007] Adopting the above technical solution, by splitting the traditional integral three-way connector into a right-angle connector and a separated third pin, compared with the traditional integral three-way component, this structure simplifies the processing technology. There is no need for complex multi-directional forming processes. Only the right-angle connector and the third pin need to be processed separately, reducing the mold development cost and production processing cost. Moreover, during on-site assembly, only the components need to be quickly inserted and then fixed through the fixing mechanism, without complex alignment and adjustment. The insertion method is convenient for pre-assembly and improves the installation efficiency; especially importantly, the space fitting structure where the right-angle side faces are fitted into the right-angle space, and the three-dimensional orthogonal fitting structure formed by a pair of right-angle abutting surfaces and the right-angle side faces at the end of the third frame bar. The right-angle side faces are forced to be constrained in the right-angle space formed by the two right-angle abutting surfaces, generating a mechanical self-locking anti-rotation effect. On the one hand, it inhibits the circumferential rotation tendency of the third frame bar by the face-to-face abutting contact, and on the other hand, it eliminates the possibility of radial crosstalk by the physical block of the right-angle abutting surface against the lateral displacement; compared with the existing non-circular tenon and mortise solutions, this design transfers the precise matching requirement from the tenon and mortise pair to the end face of the large-profile section, not only eliminating the high-cost precision machining process, but also avoiding the problem of forced knocking deformation caused by the tenon and mortise angle alignment deviation during assembly, improving the production yield and assembly smoothness; and, the fitting of the right-angle abutting surface and the side face evenly distributes the torsional moment to the end faces of the first frame bar and the second frame bar, improving the torsional stiffness and enhancing the structural stability; in addition, a surface contact sealing structure is formed at the connection, expanding the sealing surface contact area, which helps to improve the dust-proof and moisture-proof performance of the cabinet and meets the requirements of the operating environment sealing of electrical equipment.

[0008] In a possible design, the fixing mechanism includes a cylindrical tenon, a countersunk screw, a countersunk hole and a circular mortise opened in the connecting neck. The cylindrical tenon is located on the end face of the third pin and a threaded hole is opened in its center. The countersunk hole and the circular mortise are coaxially arranged. The cylindrical tenon is inserted into the circular mortise, and the countersunk screw penetrates through the countersunk hole and the threaded hole along the axis to lock the cylindrical tenon in the circular mortise.

[0009] With the above design, a cylindrical tenon and a circular mortise are adopted. During processing, only conventional processes such as drilling and turning are required, without high-precision complex molds, reducing the processing accuracy requirements and avoiding the precision processing cost of special-shaped tenon and mortise. At the same time, the circular structure is easier to align during assembly, further improving the assembly efficiency. Description of the Drawings

[0019] AsFigures 1 to 8 An efficiently assembled assembled cabinet shown, comprising a top plate 1, a door 2, two side plates 3, a back plate 4, a bottom plate 5, four columns 6, four cross beams 7, four longitudinal beams 8, eight right-angle connectors 9, eight third pins 91 and a fixing mechanism. Among them, the columns 6, the cross beams 7, and the longitudinal beams 8 respectively serve as the actual carriers of the first frame bar, the second frame bar, and the third frame bar. The first frame bar, the second frame bar, and the third frame bar can interchange roles. For example, when the first frame bar is the column 6, the second frame bar is the cross beam 7, and the third frame bar is the longitudinal beam 8; or when the first frame bar is the longitudinal beam 8, the second frame bar is the column 6, and the third frame bar is the cross beam 7, and so on for the rest of the combinations. Each frame bar has a socket hole for plugging and mating with a connector.

[0020] The right-angle connector 9 is a key connecting component, which includes a first pin 902 and a second pin 903 that are integrally connected perpendicular to each other. During the assembly process, the first pin 902 and the second pin 903 are respectively plugged into the socket holes of the first frame bar and the second frame bar. Due to the perpendicular design of the first pin 902 and the second pin 903, a right-angle space will be naturally formed at the adjacent end faces of the first frame bar and the second frame bar after plugging. A connecting neck 905 is formed at the corner position of the first pin 902 and the second pin 903. One side of the connecting neck 905 is provided with a mating surface 906 for docking with the third pin 91. The right-angle space extends to the outside of the mating surface 906 and the extending part forms a pair of right-angle abutting surfaces 671.

[0021] The third pin 91 is used in cooperation with the third frame bar. The third pin 91 is plugged into the socket hole of the third frame bar to realize the fixation of the third pin 91 and the third frame bar. The third pin 91 is fixedly connected to the connecting neck 905 through a fixing mechanism. When fixing, the end face of the third frame bar is in contact with the mating surface 906 to ensure the stability of the connection. The lateral end face of the third pin 91 has a pair of right-angle side faces 81 on the right-angle side of the end face of the third frame bar. During the installation process, the right-angle side faces 81 need to be accurately fitted into the right-angle space and closely abutted against the right-angle abutting surfaces 671. This design enables the third frame bar, after installation, to be not only fixed in the axial and radial directions through the fixing mechanism, but also effectively constrained in the circumferential direction through the fitting of the right-angle space and the right-angle side faces 81, thereby ensuring the stability and torsional resistance of the overall structure of the cabinet.

[0022] The fixing mechanism includes a cylindrical tenon 911, a countersunk screw 11, a countersunk hole 904 and a circular mortise 901 provided in the connecting neck 905. The cylindrical tenon 911 is provided on the end face of the third pin 91, and a threaded hole 912 is provided at the center of the cylindrical tenon 911. When machining the connecting neck 905, ensure that the countersunk hole 904 and the circular mortise 901 are coaxially arranged. During assembly, insert the cylindrical tenon 911 of the third pin 91 into the circular mortise 901 of the connecting neck 905. At this time, ensure that the threaded hole 912 of the pin is concentric with the countersunk hole 904 of the right-angle connector 9, and then use the countersunk screw 11 to penetrate the countersunk hole 904 and the threaded hole 912 along the axis to firmly lock the cylindrical tenon 911 in the circular mortise 901, completing the fixation of the third frame bar and the right-angle connector 9.

[0023] When actually assembling the cabinet, multiple right-angle connectors 9 can be first connected to the corresponding first frame bars and second frame bars respectively to assemble into multiple rectangular plane frames. For example, connect the upright column 6 and the cross beam 7 through the right-angle connector 9 to form the front frame or the back frame of the cabinet. After the adjacent end faces of the upright column 6 and the cross beam 7 are inserted, a right-angle space will be naturally formed. The right-angle space naturally extends to the outside of the insertion surface 906 and is exposed, and the extended exposed part forms a pair of right-angle abutting surfaces 671. The two ends of each longitudinal beam 8 are respectively inserted into a third pin 91 and fixedly connected. At this time, the tenon 911 of the third pin 91 faces outward. Then, assemble the pre-assembled rectangular plane frame and the longitudinal beam 8 with the third pin 91, and insert the tenon 911 of the third pin 91 into the circular mortise 901 of the right-angle connector 9. At this time, as the tenon 911 of the third pin 91 enters, the right-angle side surface 81 of the longitudinal beam 8 gradually enters the right-angle space, and the right-angle side surface 81 gradually approaches and fits against the corresponding right-angle abutting surface 671, completing the assembly of one right-angle position of the frame. The assembly of other right-angle positions is carried out in the same way. In this way, each component is assembled into a six-sided cubic assembled frame through the countersunk screw 11. Finally, install the top plate 1 and the bottom plate 5 on the cross beam 7, the longitudinal beam 8 and the right-angle connector 9 with screws respectively, install the back plate 4 on the upright column 6 and the cross beam 7 with screws, install the side plate 3 on the upright column 6 and the longitudinal beam 8 with screws, and install the door 2 on the upright column 6 and the cross beam 7 through hinges and door locks 2, completing the assembly of the entire assembled cabinet.

[0024] Through the above specific implementation manners, the assembled cabinet achieves the effects of simplifying the processing technology, reducing costs, improving the assembly efficiency, enhancing the structural stability and optimizing the sealing performance. By using the split right-angle connectors 9 and the third pins 91, and combining the mortise and tenon and screw fixing methods, the processing technology of the cabinet is simplified. Compared with the complex tee connection structure of traditional cabinets, the mold development cost and production processing cost are reduced. At the same time, this modular assembly method enables on-site installation without complex alignment and adjustment, greatly improving the assembly efficiency; and the multi-faceted contact connection between the frame bars ensures the stability of the overall structure of the cabinet and good sealing performance, meeting the requirements for the efficient assembly and reliable operation of cabinets in fields such as industrial automation, IT data centers and communication base stations.
