Detailed Description

As shown in fig. 1-3, the utility model provides a plug-type quick terminal box, including box body and lid 7, surround the box body that forms through the welding by side fence 1, diaphragm 2 and bottom plate 5, be equipped with slide 8 on 1 both sides wall of side fence, the corresponding slide 8 position of lid 7 inner wall is equipped with jut 9, and jut 9 cooperation slide 8 lid 7 of being convenient for stably removes on the box body, and can aim at fast when being convenient for lid 7 to install on the box body.

The bottom plate 5 is symmetrically provided with mounting holes 6, the front end of the side rail 1 and the transverse plate 2 are symmetrically provided with wire passing holes 4, the transverse plate 2 is symmetrically provided with locking holes 3, one end of the cover body 7 is symmetrically provided with locking devices 11, and the positions of the locking holes 3 correspond to the positions of the locking devices 11, so that the locking devices 11 can just pass through the locking holes 3 during installation.

The locking device 11 comprises a pin shaft 1106 symmetrically welded at one end of the cover body 7, a groove 1103 is formed at the other end of the pin shaft 1106, the groove 1103 is a double-number groove, such as a cross-shaped groove or a cross-shaped groove, an iron sheet 1101 is symmetrically arranged in the groove 1103, the iron sheet 1101 is hinged with the pin shaft 1106 through a hinge shaft 1102, the iron sheet 1101 is connected through a spring 1107, the hinge shaft 1102 is in interference fit with the iron sheet 1101, and the hinge shaft 1102 is in clearance fit with the pin shaft 1106; the fixing plate 1104 passes through the pin 1106, and the fixing plate 1104 is mounted on one end of the cover 7 by a return spring 1105.

When the cover body 7 moves on the box body in alignment with the slide rail 8, the locking device 11 is clamped on the locking hole 3, so that the cover body 7 is fixed on the box body, and a client does not need to carry a professional disassembling tool during wiring, so that the time of the client is greatly reduced; meanwhile, the fixing plate 1104 is matched with the return spring 1105, so that the cover 7 is not loosened when being fixed on the box body.
