Problems solved by technology

These two methods, on the one hand, manual operation is time-consuming and laborious, and very inconvenient; on the other hand, the use of multi-motor drive greatly improves energy consumption, and the degree of coordination of each motor is also a problem that designers need to consider. Therefore, this telescopic rod design and the production is more complicated, and the operation is inconvenient

Abstract

The invention relates to an extruding and self-locking type automatic two-grade telescoping rod structure. The extruding and self-locking type automatic two-grade telescoping rod structure comprises abase, wherein one end of a first lead screw is rotatably connected into the base, and the first lead screw can rotate along own axis; a first gear provided with a threaded hole sleeves the outer partof the first lead screw; the first lead screw penetrates through a threaded hole in the first gear; the first gear is rotatably mounted into a supporting plate; a second gear and a third gear are rotatably mounted in the supporting plate; the first gear is correspondingly engaged with the second gear and the third gear; the second gear is provided with a threaded hole, and a second lead screw which penetrates through the second gear and the supporting plate is formed in the second gear; the second gear is fixedly connected to a third lead screw; and the third lead screw extends in the direction far away from the base. According to the extruding and self-locking type automatic two-grade telescoping rod structure, two telescoping rod joints are driven to sequentially telescope through one motor, and a plurality of telescoping rod sections can be positioned while the telescoping rod telescopes, and manually operating a damping part or a positioning part is avoided; and the extruding andself-locking type automatic two-grade telescoping rod structure is convenient and quick.

Description

technical field [0001] The invention belongs to the technical field of telescopic rods, and in particular relates to an extrusion self-locking type two-stage automatic telescopic rod structure. Background technique [0002] The telescopic rod is mostly made of two or more rods, so it has the characteristics of small shrinkage volume for carrying and storage, and the expansion can meet the use length requirements. It is widely used in people's daily life, especially when people take selfies with mobile phones, the telescopic rod plays a great role, it can easily adjust the shooting distance, or the telescopic frame used to support the hanger is adopted to have a certain load capacity telescoping rod. [0003] The inventor believes that: in the current common telescopic rod structure, especially the two-section telescopic rod, the damping parts between the rods are used to realize the positioning of each rod after stretching or shrinking, or the positioning parts provided at ...
