Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description.
Example 1
The low-voltage distribution cabinet frame provided by the embodiment is a rectangular cabinet frame, as shown in fig. 1 to 7: the sliding type longitudinal beam assembly comprises a sliding type longitudinal beam assembly 1, a pair of cross beams 2, four upright posts 3, a supporting beam 4, a bus mounting beam 5, a top plate 6 and a connecting part 7. The sliding longitudinal beam assembly 1 is composed of 5 parts: the device comprises a longitudinal beam 1-1, a sliding longitudinal beam 1-2, a clamping plate 1-3, a positioning piece 1-4 and an M12 bolt assembly 1-5; the top plate 6 is provided with a folded edge 6-1.
The upright post 3 is vertically and fixedly arranged below the cross beam 2, the rear end of the longitudinal beam is fixedly connected with one of the cross beams, and one end of the sliding longitudinal beam is inserted at the front end of the longitudinal beam; when the other end of the sliding longitudinal beam is in an extending state, the sliding longitudinal beam is fixedly connected with a connecting part 7 fixedly arranged at the other transverse beam end through a bolt assembly. The bus bar mounting beam 5 is connected between the upright posts in parallel with the longitudinal beam, and the supporting beam is connected between the longitudinal beam and the bus bar mounting beam.
The positioning piece 1-4 is provided with a central fixed mounting hole, and the periphery of the fixed mounting hole is provided with a group of bosses 1-4-1.
The longitudinal beam is of a C-shaped tubular structure, and a plurality of through holes are respectively formed in the longitudinal beam and the sliding longitudinal beam; when the sliding type longitudinal beam is in an extending state, the sliding type longitudinal beam is fixedly connected with the C-shaped tubular longitudinal beam through the positioning piece and the bolt, and the boss 1-4-1 is arranged in the through hole. The setting element adopts the mode of mould punching press boss to play the effect of location, need not to reuse self-tapping screw location, and easy dismounting is simple not only, can avoid the potential safety hazard because of self-tapping screw drops and brings moreover.
