[0001] This utility model relates to a connection structure for a power distribution cabinet frame, specifically a high-strength and fast connection structure for a low-voltage power distribution cabinet frame. Background Technology

[0002] Low-voltage switchgear is a complete set of electrical devices in a power system used to receive low-voltage electrical energy (usually AC 50Hz, rated voltage 1000V and below) and to distribute, control, protect and monitor the electrical energy through internally integrated electrical components such as circuit breakers, disconnect switches, contactors, relays and instruments.

[0003] The horizontal and vertical beams inside the distribution cabinet are rigidly connected to form the basic frame of the cabinet, which provides mechanical support and structural stability, and also helps to realize electrical isolation, heat dissipation and safety protection functions. It is a basic structural component for the reliable operation of the distribution cabinet.

[0004] The connection method between the crossbeams and longitudinal beams of traditional distribution cabinet frames is relatively cumbersome, usually requiring a large number of bolts, nuts and other fasteners for connection. The installation process is time-consuming and labor-intensive, with low efficiency, making it difficult to meet the needs of rapid assembly. Moreover, after the crossbeams and longitudinal beams are connected, there is often a lack of effective support for the bottom of the crossbeams, resulting in insufficient connection strength and poor overall stability. During operation, it is prone to loosening, deformation or even damage due to vibration and other reasons, affecting the normal operation and service life of the distribution cabinet.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Please see Figures 1-9 As an embodiment of this utility model, the high-strength quick-connect structure of the low-voltage distribution cabinet frame includes a cabinet body 1. Four longitudinal beams 2 are respectively arranged on the four corners of the cabinet body 1. Eight cross beams 3 are connected to the four longitudinal beams 2. Two card seats 4 are arranged at the upper and lower ends of each longitudinal beam 2. Connecting blocks 13 are installed on both sides of each cross beam 3. An elastic locking mechanism and a separating mechanism are arranged in the card seat 4. A support mechanism is arranged at the bottom of the card seat 4. A plug-in mechanism is arranged on one side of each connecting block 13.

[0029] In this embodiment, when installing the longitudinal beams 2 and transverse beams 3 inside the cabinet 1, the insertion mechanism on one side of the transverse beam 3 is first aligned with the card holder 4 on one side of the longitudinal beam 2. Then, the insertion mechanism at one end of the transverse beam 3 is pushed into the card holder 4 by pushing. Due to the elastic design of the card holder 4, the two ends of the card holder 4 will open adaptively during the process of pushing the insertion mechanism into the card holder 4. After the insertion mechanism is fully pushed into the card holder 4, the card holder 4 returns to its original state and fixes the insertion mechanism. This allows for quick connection and installation of the transverse beams 3 and longitudinal beams 2. At the same time, the support mechanism at the bottom of the card holder 4 provides limiting support for the bottom of the insertion mechanism, improving the support for the bottom of the transverse beam 3 and achieving a high-strength connection. This structure requires eight transverse beams 3 to be inserted between four longitudinal beams 2 in sequence. However, when the transverse beams 3 need to be removed, the card holder 4 is opened by moving the separation mechanism, at which point the transverse beams 3 can be removed, facilitating disassembly and providing great convenience for the maintenance, repair, and component replacement of the distribution cabinet.

[0030] As a further embodiment of this utility model, the elastic locking mechanism includes a dividing groove 5 formed on the card seat 4 and an embedding groove 6 and a card slot 7 formed in the axial direction of the card seat 4, wherein the embedding groove 6 and the card slot 7 are interconnected.

[0031] In this embodiment, the dividing groove 5 on the card holder 4 is designed so that one end of the card holder 4 will open adaptively when it is subjected to compressive force, thereby allowing the insertion mechanism to enter the inside of the card holder 4.

[0032] As a further embodiment of this utility model, the separation mechanism includes a sliding cavity 8 formed in the card holder 4 and a sliding connecting rod 9 sliding on the sliding cavity 8, with a push rod 10 connected to one side of the sliding connecting rod 9.

[0033] In this embodiment, the push rod 10 is moved together with the sliding link 9 by pushing the push rod 10 to one side.

[0034] As a further embodiment of this utility model, the separation mechanism also includes two oblique push blocks 11 respectively disposed on the upper and lower sides of the sliding connecting rod 9 and two triangular blocks 12 disposed on the dividing groove 5, wherein the two oblique push blocks 11 are respectively attached to the oblique sides of the two triangular blocks 12.

[0035] In this embodiment, when the sliding link 9 moves, it will drive the two angled push blocks 11 at the upper and lower ends to move, so that the two angled push blocks 11 move on the two triangular blocks 12 respectively. Then, when the angled push block 11 passes on the triangular blocks 12, it will push the two triangular blocks 12 to the sides respectively. Then the force will be transmitted to the card seat 4 through the two triangular blocks 12, so that one end of the card seat 4 will open, thereby enabling the crossbeam 3 to be disassembled manually.

[0036] As a further embodiment of this utility model, the support mechanism includes a bracket 16 disposed below the card holder 4 and two locking plates 17 slidably disposed within the bracket 16, wherein a limiting groove 18 is provided on the locking plate 17.

[0037] In this embodiment, two locking plates 17 are respectively connected to both ends of the card holder 4. When the card holder 4 is opened, the two locking plates 17 will move accordingly.

[0038] As a further embodiment of this utility model, the insertion mechanism includes a plug rod 14 disposed on one side of the connecting block 13, and a limiting ring 15 is provided at one end of the plug rod 14. The limiting ring 15 is embedded in the embedding groove 6 and the card slot 7.

[0039] In this embodiment, when the crossbeam 3 is inserted and fixed, the insertion rod 14 enters from the embedding groove 6 at one end of the card seat 4. As the insertion rod 14 continues to move, the limiting ring 15 will deform and open the card seat 4. Then the insertion rod 14 drives the limiting ring 15 to be embedded into the card groove 7 for fixation. After that, the card seat 4 returns to its original state.

[0040] As a further embodiment of this utility model, the insertion mechanism also includes a reinforcing base 19 disposed at the bottom of the connecting block 13, the reinforcing base 19 cooperating with the limiting groove 18 between the two locking plates 17.

[0041] In this embodiment, when the insertion rod 14 enters the card holder 4, during the deformation and opening process of the card holder 4, the two ends of the deformation of the card holder 4 will respectively drive the two locking plates 17 to open. After the crossbeam 3 is connected, the card holder 4 returns to its original state and drives the two locking plates 17 to splice and reset. At this time, the two locking plates 17 lock the position of the reinforcing base 19 and form a supporting force to provide high-strength support to the reinforcing base 19, thereby supporting the bottom of the crossbeam 3, realizing a high-strength connection, effectively enhancing the overall stability and load-bearing capacity of the power distribution cabinet frame, and improving the reliability of operation.

[0042] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
