The utility model aims to solve the technical problems in the prior art and provides a novel screwing type high-altitude telescopic rod to overcome the defects in the prior art.

In order to achieve the purpose, the utility model discloses a novel screwing type high-altitude telescopic rod which is characterized by comprising a plurality of hollow pipe fittings which are movably sleeved end to end;

the tail end of the hollow pipe fitting positioned at the outermost part is provided with a plugging end cover, the front end of the hollow pipe fitting positioned at the innermost part is provided with a mounting hole far away from the plugging end cover, and the mounting hole is used for mounting an end head workpiece for high-altitude operation; the sleeve joint ends of every two adjacent hollow pipe fittings are telescopically fixed through joint parts;

the joint part comprises a first screw cap sleeved on the outer wall of the hollow pipe fitting and a second screw cap sleeved on the outer wall of the hollow pipe fitting, wherein the inner wall of the first screw cap is of a taper structure, an internal thread is arranged at the position of the inner wall, clamping pieces arranged in a petal manner are arranged at one end of the second screw cap, external threads meshed with the internal thread are arranged on the outer wall of each clamping piece, the inner wall of each clamping piece is sleeved with the outer wall of the hollow pipe fitting sleeved inside, and the first screw cap and the clamping pieces are fastened and screwed to realize the telescopic fixation between two adjacent hollow pipe fittings.

Preferably, the tail end of the hollow pipe fitting positioned inside is provided with a bolt in a tapered structure, the bolt is screwed with a nut, one side of the nut is in an open structure, and the tail end of the bolt is provided with a check ring for blocking the nut.

Preferably, the tail end of the hollow pipe fitting sleeved inside is provided with a tail warning mark.

Preferably, the end face of the hollow pipe fitting is in a round, oval or corner-like rectangular shape.

Preferably, the inner wall or/and the outer wall of the hollow pipe is/are provided with reinforcing ribs arranged along the axial direction thereof.

Preferably, the end of the hollow pipe fitting located at the outermost part is provided with an anti-slip layer.

The utility model has reasonable structural design, firm connection, long service life, high hardness and good toughness, and every two adjacent hollow pipe fittings are fastened in a spiral screwing mode, so the operation is convenient, and the connection is firmer as the screwing is more precise.

Meanwhile, the tail end of the hollow pipe fitting is fixed through the screw connection of the bolt and the nut in the tapered structure, the connection firmness is further improved, and the fixation of two points is realized.

Detailed Description

For a more clear description of the utility model, reference will now be made briefly to embodiments, which are illustrated in the accompanying drawings, and it will be apparent to those skilled in the art that the drawings described below are merely exemplary of the utility model, from which other drawings may be derived without inventive step.

Example one

Referring to fig. 1 to 3, the utility model relates to a novel screwing type high-altitude telescopic rod, which comprises a plurality of hollow pipe fittings 1 which are movably sleeved end to end;

the tail end of the hollow pipe fitting 1 positioned at the outermost part is provided with a plugging end cover 4, the front end of the hollow pipe fitting 1 positioned at the innermost part is provided with a mounting hole 3 far away from the plugging end cover 4, and the mounting hole 3 is used for mounting an end head workpiece for high-altitude operation; the sleeve joint ends of every two adjacent hollow pipe fittings 1 are telescopically fixed through joint parts 2;

the joint component 2 comprises a first screw cap 21 sleeved on the outer wall of the hollow pipe fitting 1 and a second screw cap 22 sleeved on the outer wall of the hollow pipe fitting 1, the inner wall of the first screw cap 21 is of a taper structure, internal threads are arranged at the position of the inner wall of the first screw cap 21, clamping pieces 23 arranged in a petal mode are arranged at one ends of the second screw cap 22, external threads 24 meshed with the internal threads are arranged on the outer walls of the clamping pieces 23, the inner walls of the clamping pieces 23 are sleeved with the outer wall of the hollow pipe fitting 2 sleeved inside, and the first screw cap 21 and the clamping pieces 23 are fastened and screwed to achieve telescopic fixation between every two adjacent hollow pipe fittings 1. And after the screw cap I21 and the clamping piece 23 are screwed and fastened with each other, the fixation of the sleeved part is realized.
