Description

Technical Field

[0001] The present application relates to the field of telescopic rods, and in particular to a long-length telescopic rod. Background Art

[0002] At present, telescopic rods are widely used in various products, including selfie sticks, telescopic clothes drying rods, telescopic umbrella handles, fishing rods, mops, telescopic electric fans, etc. Telescopic rods are retractable, easy to store, and easy to carry. When working, they can be extended to reach the required length to meet the use requirements. When not working, they can be folded up to save space and are easy to carry and store. Therefore, telescopic rods are also often used in conjunction with electric scissors or electric saws to prune high branches or pick high fruits;

[0003] In actual operation, telescopic rods are used for high-altitude operations, such as pruning branches at a high distance and picking fruits. However, the end of the existing telescopic rod will shake after being extended to the maximum length. Therefore, the telescopic rods on the market will shake after being extended, making the operation unstable.

[0004] There is no long telescopic rod that is stable after extension. Utility Model Content

[0021] Adjustment member, arranged on the locking member

[0022] The inner wall of the collar is penetrated and the penetrated part axially penetrates both sides of the collar to form openings, and the adjusting piece connects the collars on both sides of the openings.

[0023] Further, the side wall portions of the collar located on both sides of the opening are radially raised to form two steps;

[0024] The step surface portion penetrates to form a through hole corresponding to the adjusting member;

[0025] The adjusting piece is a screw, which is threadedly matched with an internal thread groove formed on the inner wall of the through hole.

[0026] Further, the locking member is composed of a pressing piece partially connected to the bottom of the step surface and a rotating rod rotatably arranged on the pressing piece;

[0027] The surface portion of the rotating rod is penetrated to form an opening corresponding to the through hole;

[0028] The screw is inserted into the opening and partially penetrates into the through hole.

[0029] Further, the pressing sheet is constructed to consist of a conflicting portion that conflicts with the step surface and a fitting portion that conflicts with the collar surface;

[0030] The abutment portion is a circular arc convex block;

[0031] When the fitting portion fits the surface of the collar, the abutting portion abuts against the step surface.

[0032] The beneficial effects of the present application are: 1. The telescopic rod is made stronger and more adaptable to a large length without shaking by thickening the outer tube and the inner tube; 2. The inner tube and the outer tube are more stably matched after extension by setting the limiting part and the ribs; 3.

[0061] The collar 51 is sleeved on the end of the outer tube 1 or the inner tube 2; specifically, the inner wall of the collar 51 is radially penetrated and the penetration portion penetrates the collar 51 along both sides of the axial direction to form a rectangular opening a51, and when the two sides of the opening a51 are close to each other, the collar 51 is tightened;

[0062] The side wall portions of the collar 51 located on both sides of the opening a51 are radially raised to form two steps 54, and the surface portion of the step 54 penetrates to form a through hole a52 corresponding to the adjusting member 53; the adjusting member 53 is a screw that is threadedly matched with an internal thread groove formed on the inner wall of the through hole a52; turning the screw can tighten the collar 51;

[0063] Specifically, the locking member 52 is composed of a pressing piece 531 partially connected to the bottom of the surface of the step 54 and a rotating rod 532 rotatably arranged on the pressing piece 531; the surface of the rotating rod 532 partially penetrates to form an opening a532 corresponding to the through hole a52; the screw is inserted into the opening a532 and partially penetrates into the inside of the through hole a52; through the setting of this structure, the distance between the pressing piece 531 and the step 54 is adjusted;

[0064] Specifically, the pressing piece 531 is constructed to consist of a resistance portion 533 that is in contact with the surface of the step 54 and a fitting portion 534 that is in contact with the surface of the ring 51; the resistance portion 533 is an arc protrusion; when the fitting portion 534 is in contact with the surface of the ring 51, the resistance portion 533 is in contact with the surface of the step 54; with this arrangement, when locking is required, it is only necessary to rotate the fitting portion 534 until it contacts the surface of the ring 51, so that the resistance portion 533 can be in contact with the surface of the step 54, thereby achieving locking.
