Description

Plastic telescopic rod of folding umbrella

Technical Field

The utility model relates to a folding umbrella field especially relates to a plastic telescopic link of folding umbrella.

Background

The umbrella is an indispensable article in daily life, and the folding umbrella has gradually replaced the straight rod umbrella to become a main umbrella due to the characteristics of small occupied space and easy carrying. Most of existing folding umbrellas comprise metal umbrella ribs, metal telescopic rods and the like, and in order to reduce the weight of the umbrella, the folding umbrellas are convenient to carry, the thicknesses of the rod walls of the umbrella ribs and the telescopic rods are also continuously reduced, and the quality is difficult to guarantee. Because the umbrella is often used in rainy days, rainwater or water vapor easily causes the metal umbrella stand to rust, which causes the difficulty of stretching or opening the umbrella. Meanwhile, due to the fact that metal is high in hardness and is often folded, the umbrella ribs and the telescopic rods are easy to break, and the service life is short.

At present, plastic umbrellas are available in the market, and the main parts of umbrella frames such as the central column and the umbrella ribs are replaced by plastic parts, so that the weight of the umbrella is reduced, and the service life of the umbrella is prolonged. However, most of these plastic umbrellas have no folding function, the upper and lower elastic joints still use exposed metal pieces, the metal elastic pieces need to be pressed when the umbrella is opened or folded, the problem that the metal elastic pieces are rusted and easy to damage also exists, and meanwhile, the safety of the metal pieces is low, so that the plastic umbrellas are not suitable for children to use.

In the figure, a rod 1, an inner tube 2, an outer tube 3, an umbrella disk 4, a sliding sleeve 5, an upper clamping female buckle 11, a lower column 12, a lower clamping female buckle 13, a base 14, an upper clamping male buckle 51, a middle fixing rod 52, a lower clamping male buckle 53, a boss 521 sleeve 522 and a boss 522.

Detailed Description

The present invention will be described in further detail with reference to examples, but the present invention is not limited thereto.

Fig. 1-5 show the preferred embodiment of the present invention, which comprises a middle rod 1, an inner tube 2 and an outer tube 3, wherein an upper snap button 11 is fixedly arranged at the upper end of the middle rod 1; the lower end of the lower column is provided with a lower column 12, and the top end of the lower column 12 is fixedly provided with a lower snap-in female buckle 13; the inner tube 2 is sleeved outside the middle rod 1, the upper end of the inner tube is provided with an umbrella disc 4, the lower end of the inner tube is fixedly connected with a sliding sleeve 5, and the sliding sleeve 5 is provided with an upper male buckle 51, a middle fixing rod 52 and a lower male buckle 53 in sequence from top to bottom; the outer tube 3 is sleeved outside the inner tube 1 and the lower column 12 and is fixedly connected with the lower column 12.

The outer tube 3 and the middle rod 1 perform telescopic motion relative to the inner tube 2, and a lower clamping male buckle 53 of the sliding sleeve 5 is matched and clamped with the lower clamping female buckle 13 in an initial retracting state; when the extension is extended, the inner tube 2 is fixed, the outer tube 3 can be pulled out, the middle rod 1 is driven by the lower column 12 to move downwards, the sliding sleeve 5 slides in the middle rod 1 until the upper clamping male buckle 51 of the sliding sleeve 5 is matched and clamped with the upper clamping female buckle 11, and the extension action is completed.
