Description
Affiliated technical field
The utility model relates to a kind of device of changing electric light, the roof electric light changer that especially can conveniently the electric light of house ceiling be changed without ladder.
Background technology
At present, the instrument of known replacing roof electric light is a ladder, after the electric light that is installed in the house ceiling has been broken, utilizes ladder can electric light be changed.But, ladder now not only expensive, parking space big, move trouble, and the people to climb to the eminence operation also not too safe.
The utility model content
For overcome now the ladder parking space big, move trouble; Not too safe deficiency when changing electric light, the utility model provides a kind of roof electric light changer, and this changer not only can be convenient for changing the electric light on the roof without ladder; And cost is low, placement space is little, safe in utilization.
The utility model solves the technical scheme that its technical problem adopted: be made up of live splint, outer tube, a fork, interior bar, nose cone and spring.Outer tube is designed to hollow circular-tube, and its upper end symmetry makes a pair of fork, and the distance between two forks makes one section internal thread greater than outer tube diameter on the top of outer tube; Live splint is made up of two identical intermediate plates of specification, and symmetry is rotatably installed in a upper end of fork, and the circular arc chuck is processed in the upper end of live splint, and outside open folder tail is processed in the lower end; Spring is installed in folder tail place, and its two ends are connected with two intermediate plates respectively, are contraction state; Interior bar is arranged on outer tube inside, and its upper end is fixedly connected a up-small and down-big nose cone, and nose cone is positioned within the folder tail; Top at interior bar makes one section external screw thread; This external screw thread is connected with the internal thread spiral of outer tube, and bar moves up nose cone or moves down in the rotation, the opening with closed of may command live splint chuck.During practical operation, make chuck aim at socket, the interior bar that turns clockwise then, nose cone moves up; The folder Caudad is opened outward, and then the chuck closure is held socket tightly, and inhour is rotated outer tube then; So just, can the electric light that burn out be taken off, make chuck hold new lamp holder tightly, make lamp holder aim at the installation site then otherwise use the same method; Clockwise rotate outer tube, just can new lamp be installed, reached the purpose that just can be convenient for changing house ceiling electric light without ladder.
The beneficial effect of the utility model is, can be convenient for changing the electric light that is installed in the house ceiling without ladder, and is safe and practical, only by outer tube and interior bar control live splint, simple in structure.
