Abstract
The utility model discloses a telescopic electric power pull rod, including the first body of rod and the second body of rod, the first body of rod and the second body of rod are the cylinder, the first body of rod is the hollow tube, and the second body of rod is installed in the inside of the first body of rod, the lantern ring is installed at the top of the second body of rod, be provided with extension spring between the inside bottom of the bottom of the second body of rod and the first body of rod. This telescopic electric power pull rod's the second body of rod sets up inside the first body of rod, when needs use, the second body of rod is pulled out hard to the first body of rod of holding with a firm grip, pass as stationary hump behind the opening of the spacing ring of the first body of rod, it utilizes stationary hump to fix the second body of rod to rotate the second body of rod, prevent inside the first body of rod of second body of rod withdrawal, after finishing using, the opening that rotates second body of rod messenger stationary hump and spacing ring is on same plane, and inside the effort that utilizes extension spring withdraws the first body of rod with the second body of rod.
Description
Technical field
The utility model relates to pull bar technical field, is specially a kind of telescopic Electric power pull staff.
Background technology
Along with rapid development of economy, use the quantity of low-voltage comprehensive distribution box more and more higher in low-voltage network, low voltage knife switch in low-voltage comprehensive distribution box is generally arranged on the height on distance about 2 meters, ground, and when power consumption equipment breaks down, just need the Low voltage knife switch of leaving behind in distribution box with Electric power pull staff, the power supply of power consumption equipment is cut off with this, depositing and carrying for the ease of Electric power pull staff, general three joints or four that are designed to by Electric power pull staff save pull bar combination of monomers structures, owing to mostly adopting screw socket docking between pull bar monomer, assembly operation step is comparatively loaded down with trivial details, in addition, after pull bar monomer splits, scattered placement is easily lost, three joints or four joint pull bar monomers are also needed to bundle, increase the workload of administrative staff, for this reason, we propose a kind of telescopic Electric power pull staff.
Utility model content
The purpose of this utility model is to provide a kind of telescopic Electric power pull staff, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of telescopic Electric power pull staff, comprise first body of rod and second body of rod, described first body of rod and second body of rod are cylinder, and the diameter of first body of rod is greater than the diameter of second body of rod, described first body of rod is hollow pipe, second body of rod is arranged on the inside of first body of rod, and matched in clearance is installed between first body of rod and second body of rod, the top of described second body of rod is provided with the collar, is provided with extension spring between the bottom of described second body of rod and the first body of rod inner bottom.
All spacing ring is installed bottom the inner surface top of described first body of rod and the outer surface of second body of rod, and the spacing ring inner surface of first body of rod is provided with opening, the side of second body of rod and the top being positioned at spacing ring is provided with the fixed lobe corresponding with opening.
Preferably, the outer surface of described first body of rod is socketed with insulation rubber sleeve, and the surface of insulation rubber sleeve is provided with the anti-slip veins of convex.
Preferably, the described collar is ellipse, and is coated with one deck electro-insulating rubber at the collar.
Preferably, the length of described first body of rod is less than the length of second body of rod.
Compared with prior art, the beneficial effects of the utility model are: second body of rod of this telescopic Electric power pull staff is arranged on the first body of rod inside, when it is desired to be used, first body of rod of holding with a firm grip pulls out second body of rod, after fixed lobe passes the opening of the spacing ring of first body of rod, rotating second body of rod utilizes fixed lobe to fix second body of rod, prevent second body of rod, first body of rod of retracting inner, after finishing using, rotating second body of rod makes the opening of fixed lobe and spacing ring in same plane, and it is inner to utilize the active force of extension spring second body of rod to be recovered to first body of rod.
