Description

Wall bushing Technical Field The application relates to the technical field of electrical equipment, in particular to a wall bushing. Background The wall bushing is widely applied to a power switch cabinet of a power supply system, and plays roles of excessive connection and insulation isolation on a high-voltage power supply line passing through the power switch cabinet. In the related art, the wall bushing comprises a mounting plate, a bushing and a bolt, wherein a mounting hole is formed in the mounting plate, a connecting hole communicated with the mounting hole is formed in a side plate of the electrical cabinet, the bolt sequentially passes through the mounting hole and the connecting hole, and the bolt is screwed and fixed through a nut. In view of the above-mentioned related art, the inventor believes that when installing the wall bushing, it is necessary to hold the wall bushing with hands to align the installation hole with the connection hole, which is inconvenient to install. Disclosure of utility model In order to facilitate the installation of the wall bushing, the application provides the wall bushing. The application provides a wall bushing which adopts the following technical scheme: The utility model provides a wall bushing, includes insulating tube, mounting panel, screw rod, nut and installed part, the mounting panel install in insulating tube periphery side, offered on the mounting panel and supplied the through-hole that the screw rod worn to establish, nut threaded connection in on the screw rod, the installed part includes sleeve pipe, connecting strip and buckle, the sleeve pipe coaxial set up in the through-hole, the connecting strip is provided with many, the connecting strip is followed sleeve pipe axle center circumference interval sets up, the buckle set up in the connecting strip is kept away from one side of sheathed tube. Through the technical scheme, when the wall bushing is required to be installed, the bushing can be inserted into the through hole, the pupil on the mounting plate is aligned with the connecting hole of the wallboard, the connecting strip is inserted into the connecting hole, when the connecting strip is completely inserted into the connecting hole, the buckle is clamped onto the side wall of the wallboard, the bolt can be aligned with the bushing to be inserted, and the nut is connected onto the bolt, so that the wall bushing is convenient to install. Optionally, a limiting ring is arranged at one end of the sleeve away from the connecting strip. Through above-mentioned technical scheme, in the sleeve pipe inserts the through-hole, the spacing ring carries out spacingly to the sleeve pipe, reduces the risk that the sleeve pipe directly slipped out from the connecting hole. Optionally, a notch is provided at the connection between the connecting strip and the sleeve. Through above-mentioned technical scheme, through setting up the incision, be soft connection between messenger's connecting strip and the sleeve pipe, can not interfere when the connecting strip inserts in the connecting hole, made things convenient for the installation. Optionally, the incision is V-arrangement, the opening of incision is kept away from the one side setting of sleeve pipe axle center. Through the technical scheme, the connecting strip turns over in the sleeve shaft center along the notched junction, then the bolt is aligned with the sleeve and inserted, the bolt extrudes the connecting strip outwards, so that the connecting strip is abutted to the wall of the connecting hole, and the buckle can be clamped on the side wall of the wallboard at the moment. The wall bushing has the beneficial effects that when the wall bushing is required to be installed, the bushing can be inserted into the through hole, then the pupil on the mounting plate is aligned with the connecting hole of the wallboard, so that the connecting strip is inserted into the connecting hole, when the connecting strip is completely inserted into the connecting hole, the buckle is clamped onto the side wall of the wallboard, at the moment, the bolt can be aligned with the bushing for insertion, and then the nut is connected onto the bolt, so that the wall bushing is convenient to install.
