Description

Technical Field

[0001] The present invention relates to the technical field of power distribution electrical appliance installation equipment, and in particular to a mounting assembly for power distribution electrical appliances. Background Art

[0002] Existing distribution appliances, such as small circuit breakers and fuses, are fixedly connected to the metal guide rails in the distribution cabinet through slots formed on their rear panels. During fixed installation, the slots of the distribution appliances are slid in from one side of the guide rail. In this way, when multiple distribution appliances are installed side by side on the guide rail, if a distribution appliance located in the middle position fails and needs to be replaced, the installer can slide the multiple distribution appliances located on one side of the faulty distribution appliance out along the side of the guide rail and then remove the faulty distribution appliance, or use a flat-blade screwdriver to increase the slot gap of the faulty distribution appliance and then remove it from the guide rail. The above two disassembly methods are both time-consuming and labor-intensive, and increase the cost of maintenance and replacement. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that the distribution electrical appliances are difficult to disassemble from the guide rails, thereby providing an installation assembly for the distribution electrical appliances that is quick and convenient to disassemble and assemble and has low maintenance and replacement costs.

[0007] The slide groove is a dovetail groove, and the slide rail is in a dovetail shape that matches the dovetail groove.

[0008] It also includes a locking structure for locking the relative sliding position of the first mounting seat and the second mounting seat.

[0009] The locking structure includes a locking piece, a through-hole and an open slot. The locking piece has a first plug-in block formed at the bottom and connectable to the first mounting seat, and a second plug-in block formed at the top and connectable to the second mounting seat. The first plug-in block is elongated, and the maximum size of the first plug-in block is larger than that of the second plug-in block; the through-hole is provided at the top of the second mounting seat, and is adapted to be plugged into the second plug-in block; the open slot is provided at the top of the first mounting seat, and its opening is arranged upward. The size of the open slot is adapted to the length of the elongated first plug-in block, and the opening is adapted to the width of the elongated first plug-in block; the locking piece has an initial position in which the second plug-in block is inserted into the opening, and a locking position in which the second plug-in block is inserted into the open slot and rotated a certain angle.

[0010] The locking piece is positioned and connected to the second mounting seat through a positioning and mounting structure. The positioning and mounting structure includes a positioning groove and a positioning protrusion. There are multiple positioning grooves, which are evenly spaced on the inner wall of the through hole; the positioning protrusion is provided on the outer wall of the second plug-in block and can be positioned and connected to the positioning groove.

[0011] The second plug block is formed with a slot for inserting a flat-blade screwdriver to drive the locking member to rotate, wherein in the initial position, the slot is vertically arranged, and in the locking position, the slot is horizontally arranged.

[0012] The locking structure is a bolt that can fix the first mounting seat and the second mounting seat.

[0013] A first slot adapted to engage with the guide rail is formed on the back of the first mounting seat.

[0014] The first mounting seat and the guide rail are integrally formed.

[0015] The front side of the second mounting seat is formed with a card seat that can be adapted to be connected with the second card slot on the rear panel of the power distribution appliance.

[0016] The second mounting base and the power distribution appliance are integrally formed.

[0017] The technical solution of the present invention has the following advantages:
