Description

Technical Field

[0001] The utility model relates to the technical field of internal frames of power distribution cabinets, in particular to a highly firm and replaceable internal frame structure of a cabinet. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet, which is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load.

[0003] The existing distribution cabinet is provided with a frame structure inside, which is similar to a shelf. The horizontal frame is fixed to the column of the back plate of the distribution cabinet by bolts. As the number of electrical components increases, the position of the horizontal frame needs to be adjusted. Due to the small internal space of the distribution cabinet, it is inconvenient to disassemble and assemble the bolts, which makes the distribution cabinet inconvenient to use. Therefore, a highly firm and replaceable cabinet frame structure is proposed. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides a technical solution, a highly robust and replaceable cabinet frame structure, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,include:

[0027] The cabinet 1 has support inner columns 5 on both sides of the rear end of the cabinet 1, and the support inner columns 5 are fixedly connected to the cabinet 1;

[0028] A crossbar 6 is arranged between the two supporting inner columns 5, and both ends of the crossbar 6 are provided with fixing half rings 9;

[0029] The inner cavity 12 is arranged at the left and right ends of the crossbar 6, and a plug rod 13 is installed inside the inner cavity 12. A plurality of equally spaced plug holes 8 are arranged on one side of the inner support column 5 close to the plug rod 13, and the plug rod 13 is adapted to the plug holes 8;

[0030] The return spring 14 is arranged on a side of the outside of the insertion rod 13 away from the insertion hole 8 .

[0031] See also Figure 3 and Figure 4 A pull rod is provided at the lower end of the insertion rod 13 , and the pull rod is fixedly connected to the insertion rod 13 , the pull rod passes through and extends to the outside of the cross bar 6 , and the pull rod is used to move the insertion rod 13 .

[0032] See also Figure 2 , Figure 3 and Figure 4 A plurality of equally spaced fixing holes 7 are provided inside the cross bar 6, and the fixing holes 7 are integrally formed with the cross bar 6, and the fixing holes 7 are used for installing electrical components in the power distribution cabinet.

[0033] See also Figure 3 and Figure 4 A limiting inner ring 10 is slidably installed inside the fixed half ring 9, and a hand-tightening bolt 11 is installed on one side of the outer side of the fixed half ring 9. The hand-tightening bolt 11 is connected to the fixed half ring 9 through threaded cooperation, and the hand-tightening bolt 11 is used to fix the limiting inner ring 10.

[0034] See also Figure 1 and Figure 2A cabinet door 2 is installed on one side of the front end of the cabinet body 1, and the cabinet door 2 is rotatably connected to the cabinet body 1 through a hinge, and the cabinet door 2 is used to close the cabinet body 1.

[0035] See also Figure 1 and Figure 2 Support legs 4 are arranged at the four corners of the lower end of the cabinet body 1 , and the support legs 4 are connected to the cabinet body 1 through threaded cooperation. A turntable 3 is arranged at the upper end of the support legs 4 , and the turntable 3 is used to rotate the support legs 4 .

[0036] The working principle of this device is as follows: when the cabinet 1 is placed, the height of the supporting legs 4 is changed by rotating the turntable 3. By changing the four supporting legs 4, the placement of the cabinet 1 is more stable. When installing the cross bar 6, the pull rod is pulled to move the insertion rod 13 toward one side of the reset spring 14. The reset spring 14 is compressed and deformed under force, and the fixed semi-ring 9 is sleeved on the outside of the supporting inner column 5. The insertion rod 13 is aligned with the insertion hole 8. The pull rod is loosened, and the reset spring 14 resets and pushes the insertion rod 13 so that one end is inserted into the insertion hole 8, thereby fixing the fixed semi-ring 9, making the installation of the cross bar 6 more convenient. When disassembling, the operation can be reversed. In this way, the replacement of the cross bar 6 is more convenient, and the limiting inner ring 10 is pushed backward. Then the hand-tightening bolt 11 is turned to support the limiting inner ring 10. The combination of the limiting inner ring 10 and the fixed semi-ring 9 wraps the supporting inner column 5, thereby improving the firmness of the connection between the fixed semi-ring 9 and the supporting inner column 5.
