Description

Technical Field

[0001] This utility model belongs to the field of conductive tube technology, and in particular relates to a telescopic conductive tube locking structure. Background Technology

[0002] A conductive tube is a tubular material with conductive properties, usually made of metal (such as copper, aluminum, stainless steel, etc.) or conductive composite materials. It is used to transmit current, electromagnetic signals, or as a carrier for electromagnetic shielding, grounding, and other functions.

[0003] Regarding locking stability, some locking structures are prone to wear or jamming after long-term use. For example, some locking structures using simple buckles will gradually deform as the telescopic tube frequently extends and retracts, resulting in a decrease in locking force and making it impossible to reliably fix the telescopic tube in the required position, affecting the normal use and safety of the conductive tube. Utility Model Content

[0004] The purpose of this invention is to address the issue that some locking structures are prone to wear or jamming after prolonged use, affecting locking stability. For example, some locking structures using simple buckles gradually deform as the telescopic tube extends and retracts, leading to a decrease in locking force and making it impossible to reliably fix the telescopic tube in the required position, thus affecting the normal use and safety of the conductive tube. Therefore, this invention proposes a telescopic conductive tube locking structure.

[0009] One end of the connecting sleeve is connected to the outer tube by a screw, and the other end is fitted onto the inner telescopic tube.

[0010] As a further description of the above technical solution:

[0011] One end of the button is rotatably connected to the connecting sleeve via a connecting shaft, and a pressing block is provided at the bottom of the button, with an abutting inclined surface on the pressing block.

[0013] The connecting sleeve is provided with a connecting groove, and the pushing block is elastically installed in the connecting groove by a spring. The end of the pushing block is provided with a pushing inclined surface, and the abutting inclined surface abuts against the pushing inclined surface.

The outer tube is provided with a second connector, and a second conductive strip is provided on the first connector. The first conductive strip and the second conductive strip abut against each other.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] 1. In this utility model, by setting a locking structure composed of a connecting sleeve, a button, a pushing block, and a limiting block, when the inner telescopic tube needs to extend or retract inside the outer tube, simply press the button to make the button rotate along the connecting shaft, thereby causing the abutting inclined surface at the bottom of the pressing block to push the pushing block inward until the top of the limiting block enters the slot. Then, by pulling the inner telescopic tube, the extension or retraction is completed. When locking is required, the pushing block automatically resets under the influence of the spring, and the bottom of the limiting block is located in the limiting groove, while the top is away from the slot, thereby achieving locking. Compared with the traditional buckle structure, this structure is more stable.

[0022] 2. In this utility model, by making the top and bottom of the limiting block, the limiting groove and the slot cross-section all trapezoidal, the force can be decomposed when the inner telescopic tube is pulled, so as not to affect the extension and contraction of the inner telescopic tube.
