Embodiment 1

[0031] like Figures 1 to 4 As shown, this embodiment provides a retractable insulating rod, the retractable insulating rod includes a working head 1 and a telescopic portion 2, and the telescopic portion 2 includes N+1 telescopic tubes 21, N locking structures 22 and springs 23, N is an integer greater than or equal to 1, N+1 telescopic tubes 21 are set in sequence from the inside to the outside, any two adjacent telescopic tubes 21 are slidably matched, and a lock is provided between any two adjacent telescopic tubes 21 The locking structure 22 is used for locking or unlocking the relative positions of the two adjacent telescopic tubes 21. In any two adjacent telescopic tubes 21, the spring 23 can drive the inner telescopic tube 21 relative to the outer side. The telescopic tube 21 is extended. The initial state of the device is the retracted state. During operation, the worker roughly estimates how many telescopic tubes 21 need to be unlocked by visually measuring the dist...

Embodiment 2

[0040] The second embodiment, the only difference between this embodiment and the first embodiment is that the sliding rail 24 and the sliding groove 25 are removed, and the cross section of the telescopic tube 21 is designed to be oval.

Abstract

The invention relates to the technical field of insulating rods and particularly discloses a telescopic insulating rod. The telescopic insulating rod comprises a working head and a telescopic part, wherein the telescopic part comprises N+1 telescopic pipes, N locking structures and a spring, N is an integer greater than or equal to 1, the N+1 telescopic pipes are sequentially sleeved from inside to outside, and any two adjacent telescopic pipes are in sliding fit; the telescopic pipes are arranged in parallel, a locking structure is arranged between any two adjacent telescopic pipes, the locking structure is used for locking or unlocking the relative positions of the two adjacent telescopic pipes, and in any two adjacent telescopic pipes, the spring can drive the telescopic pipe located onthe inner side to stretch out relative to the telescopic pipe located on the outer side. The telescopic insulating rod is simple and rapid to operate.

Description

technical field [0001] The invention relates to the technical field of insulating rods, in particular to a retractable insulating rod. Background technique [0002] Insulation operating rod is an important tool in power grid enterprises, and it is a necessary tool for grass-roots operation and maintenance teams to go out. People generally use the traditional insulating operating rod. The insulating operating rod is made of multi-section operating rods. During the screwing process, it is necessary to find the corresponding rod for screwing. Due to the work in the field, the insulating operating rod has many parts. Because it is metal, it is prone to rust, so in the actual use process, the threaded part of the insulating operating rod often rusts, and if the screw at the connection is not installed properly, it will fall out, and there is a high-altitude operation. It is not easy to remove it when it is removed. Therefore, the traditional insulating operating rod greatly affe...
