Description

Technical Field

[0001] This utility model belongs to the field of control cabinet technology, and specifically relates to an assembled control cabinet. Background Technology

[0002] A control cabinet is a metal cabinet or panel in which switching equipment, measuring instruments, protective devices, and auxiliary equipment are assembled according to electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system, facilitate maintenance, and not endanger personnel or surrounding equipment. During normal operation, circuits can be connected or disconnected manually or automatically. In case of faults or abnormal operation, protective devices will disconnect the circuit or trigger an alarm. Measuring instruments can display various operating parameters, allow adjustment of certain electrical parameters, and provide alerts or signals for deviations from normal operating conditions.

[0003] Currently, a Chinese utility model with announcement number CN219576292U discloses an assembled control cabinet. Most control cabinets are currently assembled by welding. Due to the large size of some cabinets, there are difficulties in delivery due to space constraints and manual handling. Utility Model Content

[0004] The purpose of this utility model is to provide an assembled control cabinet, which has the advantage of being able to be quickly installed and disassembled.

[0006] The above technical solution allows for quick assembly of the modular cabinets when needed via an expansion and splicing mechanism. Furthermore, when not assembled, the modular cabinets can be easily expanded, facilitating handling and transportation.

[0007] The present invention is further configured such that a connecting rod is movably mounted at the center of the protective shell, and a knob is fixedly mounted at one end of the connecting rod.

[0008] The above technical solution involves fixing a knob to one end of a connecting rod, which can rotate the connecting rod when the knob is turned.

[0009] The present invention is further configured such that the end of the connecting rod away from the knob moves through the protective shell and has a threaded end, and a limiting disc is fixedly installed at the end of the connecting rod near the threaded end.

[0010] The above technical solution is adopted: the end of the connecting rod away from the knob moves through the protective shell and has a threaded end, which can drive the movable sleeve to move back and forth when the threaded end rotates.

[0011] The present invention is further configured such that a movable sleeve is movably mounted on the outer surface of the threaded end, and a plurality of rectangular protrusions are fixedly mounted on the outer surface of the movable sleeve in a circumferential manner.

[0012] The above technical solution involves fixing several rectangular protrusions in a circular pattern on the outer surface of the movable sleeve column, which can move the rectangular protrusions together with the movable sleeve column after it moves.

[0013] The present invention is further configured such that each of the rectangular protrusions has an elliptical movable rod movably mounted at both ends via a rotation axis, and an elliptical connecting block is movably mounted at the end of the elliptical movable rod away from the rectangular protrusion via a rotation axis.

[0014] The above technical solution is adopted: an elliptical connecting block is movably installed at the end of the elliptical movable rod away from the rectangular protrusion via a rotating shaft. When the movable sleeve moves, the elliptical movable rod gradually rises under the restraint.

[0015] The present invention is further configured such that an L-shaped connecting claw is fixedly installed on the outer surface of the elliptical connecting block, the L-shaped connecting claw is movably clamped inside the clamping groove, the clamping groove is opened inside the clamping connecting block, and the clamping connecting block is fixedly installed on the combined cabinet.

[0016] The above technical solution involves using an L-shaped connecting claw that is movably locked inside the locking groove. Under the lifting action of the elliptical moving rod, the L-shaped connecting claw will be locked inside the locking groove, facilitating rapid splicing.

[0017] The present invention is further configured such that a rectangular slider is fixedly installed at the end of the L-shaped connecting claw away from the elliptical connecting block, and the rectangular slider is movably installed inside the rectangular groove.

[0018] The above technical solution is adopted: a rectangular slider is fixedly installed at the end of the L-shaped connecting claw away from the elliptical connecting block, which can change the translation force into upper body force during use.

[0019] The present invention is further configured such that the rectangular groove is formed inside the cross-shaped fixing block, and the cross-shaped fixing block is fixedly installed inside one end of the protective shell by a connecting rod.

[0020] The above technical solution involves fixing the cross-shaped fixing block inside one end of the protective shell via a connecting rod, which allows for restriction during use.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. By rotating the knob in the expansion splicing mechanism, the connecting rod will also rotate. At this time, the threaded end of the connecting rod will drive the movable sleeve to move, and the movable sleeve will drive the elliptical movable rod to move. At this time, the elliptical movable rod will change the translation angle under the action of the rectangular slider and the rectangular slide groove, and will be lifted. At this time, the L-shaped connecting claw will lock, which facilitates quick splicing during use, and facilitates transportation and manual handling.

[0023] 2. When the L-shaped connecting claw moves upward, it will gradually lock into the inside of the locking groove. The locking groove is opened inside the locking connecting block. The locking connecting block is combined with the cabinet connection. When needed, it can be used with the expansion splicing mechanism for quick splicing, which is convenient for transportation and manual handling. Attached Figure Description
