Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction tools, in particular to an electric telescopic insulating rod which is easy to store. Background Art

[0002] Insulating rods are generally used in high-voltage live working situations. For example, lightning arresters, as important power equipment, play a role in limiting overvoltage. Live leakage current testing is an important means of detecting lightning arresters. Lightning arresters are generally located at a high position, and live leakage current testing requires the use of insulating rods to hang down leads to the leakage current test host.

[0003] At present, in the prior art, a Chinese patent with a publication number of CN205355683U discloses a retractable electric insulating operating rod. The device is provided with an A rod, which is composed of a plurality of rods of different lengths. The total length of the entire operating rod can be adjusted by replacing the A rod to meet the needs of working at different heights. However, in actual use, the device is frequently replaced, which not only causes a certain degree of wear on the device, but also affects the work efficiency of the staff. In view of this, we propose an electric retractable insulating rod that is easy to store. Utility Model Content

[0008] A sliding groove, wherein one end of the sliding rod away from the rotating gear is slidably connected to the sliding groove provided on the inner wall of the insulating rod;

[0009] and a sliding rack, wherein the sliding rack is meshedly connected with the rotating gear.

[0010] Preferably, an articulated seat is provided on the outer wall of the clamping sleeve, and the positioning function of the insulating rod is realized through the rotational connection between the articulated seat and the press locking device.

[0011] Preferably, the push locking device includes a rotating shaft, which passes through the inner wall of the hinge seat and is rotatably connected to the pressing block.

[0017] (1) The electric telescopic insulating rod that is easy to store is provided with an insulating transmission component. By pressing the insulating tube section inward, the connecting block drives the sliding rack to move in a uniform linear motion. The sliding rack is meshed with the rotating gear, which in turn affects the linkage movement of the rotating gear and the fixed rack. The sliding rack and the rotating gear move backward under the action of the fixed rack, and the rotating gear slides backward on the sliding groove through the sliding rod.

[0018] (2) The electric telescopic insulating rod that is easy to store is provided with a push-locking device. After the insulating pipe section is retracted to a specified length, the positioning block is clamped in a certain slot of the array slot to realize the positioning function. When the positioning restriction is released, one end of the pressing block is pressed to cause the rotating shaft to start moving. The reset spring is tightened to drive one end of the pressing block to move inward, and the other end of the pressing block immediately drives the positioning block to separate from the outer wall of the handheld pipe section.
