Description

Technical Field

[0001] This utility model relates to the field of umbrella rods, and in particular to an umbrella rod for an electric umbrella with a built-in drive mechanism. Background Technology

[0002] The umbrella strut is an important component of the umbrella frame structure, usually located in the center of the umbrella, connecting the canopy and the handle. Its main function is to support the canopy, ensuring the stability and durability of the umbrella when it is opened and closed.

[0003] A known Chinese patent (application number: CN201721293486.8) discloses a multi-fold umbrella center rod, comprising: an outer tube and an inner tube connected by inner and outer sleeves, and may further include one or more middle tubes; the cross-sections of the outer tube, middle tube, and inner tube all have two long sides and two or more short sides, the short sides being distributed on both sides of the two long sides, and the long sides of the cross-sections of the outer tube, middle tube, and inner tube are arranged parallel to each other, with the long sides of the cross-sections of adjacent tubes being close to each other. This invention provides a tight fit between the multi-fold umbrella center rod and the lower fin, as well as between each section of the tubes, preventing it from easily detaching and avoiding the defects of existing multi-fold umbrella center rods that are prone to rotation and twisting.

[0004] Electric umbrellas require mechanical and electronic components, which are usually installed inside the umbrella handle at the bottom of the umbrella stick. However, existing methods require tools to disassemble the umbrella handle when repairing the mechanical and electronic components inside the handle, which is troublesome and affects the repair efficiency. Therefore, an electric umbrella stick with a built-in drive mechanism is proposed. Utility Model Content

[0005] To address the aforementioned issues, this invention proposes a central rod for an electric umbrella with a built-in drive mechanism. This addresses the problem that electric umbrellas require mechanical and electronic components, which are typically installed inside the umbrella handle at the bottom of the central rod. However, existing methods require tools to disassemble the handle for maintenance of these mechanical and electronic components, which is cumbersome and affects maintenance efficiency.

[0006] To achieve the above objectives, this utility model provides a central rod for an electric umbrella with a built-in drive mechanism, comprising:

[0007] The umbrella's central rod and two umbrella handle shells;

[0008] Multiple limiting holes are provided on both sides of one of the two umbrella handle housings, a slot is provided on one side of the other of the two umbrella handle housings, and a wedge plate is fixedly installed on one side of one of the two umbrella handle housings, with the wedge plate being inserted into the slot.

[0009] Multiple sliding grooves are formed on the rear side of the inner wall of the slot. A sliding plate is slidably connected inside the multiple sliding grooves. A limit block is fixedly installed on one side of the sliding plate. The limit block is inserted into multiple limit holes. A first spring is fixedly installed on one side of the inner wall of the multiple sliding grooves. One end of the first spring is connected to the sliding plate.

[0010] Furthermore, a plurality of second springs are fixedly installed on one side of the inner wall of the slot, and one end of the plurality of second springs is fixedly connected to an abutment plate, and one side of the abutment plate abuts against the wedge plate.

[0011] Furthermore, two protective sleeves are provided opposite to each other on the outer side walls of the two umbrella handle shells, and the outer side walls of the two protective sleeves are provided with multiple anti-slip protrusions.

[0012] Furthermore, a retaining ring is provided at the bottom of one of the two umbrella handle housings, and an umbrella cord is provided on the retaining ring.

[0013] Furthermore, the outer wall of the umbrella rod is coated with an anti-corrosion coating, specifically an epoxy resin coating.

[0014] Furthermore, an anti-rust coating is applied to the outer wall of the anti-corrosion coating away from the umbrella rod, specifically an oil-based anti-rust agent.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] When it is necessary to disassemble the two umbrella handle housings, one umbrella handle housing is pulled to one side to separate the wedge plate from the slot. The first spring returns to its original position and drives the slide plate to slide inside the groove, causing the limiting block to disengage from the limiting hole. This allows the two umbrella handle housings to be disassembled. When installing the two umbrella handle housings, the wedge plate is inserted into the slot. At the same time as insertion, the wedge plate squeezes the slide plate, which slides inside the groove, stretching the first spring. The limiting block is inserted into the slot for limiting and fixing. This achieves the purpose of facilitating the installation and disassembly of the umbrella handle housings and effectively improves work efficiency.
