Description

Technical Field

[0001] The utility model belongs to the technical field of outdoor tents, and in particular relates to a novel handrail locking mechanism for an outdoor umbrella. Background Art

[0002] As an outdoor leisure tool, outdoor parasols are widely used in leisure places such as squares, beaches, parks and courtyards, providing people with a comfortable space to enjoy the cool. The outdoor parasols currently used are usually divided into hanging umbrellas and center column umbrellas due to the location of the umbrella surface. Among them, the hanging umbrella has a larger area at the bottom of the umbrella surface due to the side suspension structure of the umbrella surface, and has a good use effect. In particular, the Roman umbrella has a large front inclination and a large area under the umbrella. The overall structure of the Roman umbrella is firm and stable, and the frame is made of aluminum alloy. The overall design reveals a simple and atmospheric style.

[0003] The opening and closing of existing Roman umbrellas all need to be controlled by a crank, and in order to facilitate the winding of the rope, the position of the crank sometimes needs to be adjusted. At present, the crank of the parasol is generally set on the armrest shell, and the position of the crank can be adjusted by moving the armrest shell. The armrest shell moves up and down along the umbrella column to adjust the tilt angle of the umbrella surface, and also facilitates the subsequent opening and closing operation of the umbrella surface.

[0004] Traditional armrest shells are usually locked to the pole using spring structures such as spring beans. The disadvantage of this locking structure is that the armrest shell can only be locked at a specific position on the pole, and the position of the armrest shell on the pole cannot be adjusted, so the angle of the umbrella cannot be adjusted by moving the armrest shell. In addition, the spring-type locking structure is easy to loosen, causing the armrest shell to shake after the umbrella is opened, which in turn causes the umbrella to shake, affecting the use.
