Embodiment

[0015] Such as Figure 1-Figure 2 As shown, a waterproof pad for an umbrella, the waterproof pad 2 is a double-layer structure composed of an upper gasket and a lower gasket coaxially connected, a gap for holding the umbrella cloth 1 is reserved between the upper gasket and the lower gasket, and the umbrella cloth 1 is closely attached to the upper gasket The lower connection of the upper washer and the lower washer form an angle α, and the diameter of the upper washer is larger than the diameter of the lower washer.

[0016] The waterproof pad 2 is made of plastic rubber.

[0017] The diameter of the upper washer is 75mm, and the diameter of the lower washer is 33mm.

[0018] The included angle α is 158 degrees.

[0019] Assembly of the invention image 3 As shown, the EPDM material (commonly known as plastic rubber) is used for injection molding, and the appearance is smooth and uniform. It adopts a double-layer design, and the inner and outer layers of the umbrella cloth...

Abstract

The invention relates to the technical field of outdoor goods, in particular to an umbrella waterproof pad. The waterproof pad is of a dual-layer structure formed by coaxially connecting an upper padring with a lower pad ring. A gap for clamping umbrella fabric is reserved between the upper pad ring and the lower pad ring. The umbrella fabric is connected with the lower portion of the upper pad ring in a closely attached mode. An included angle is formed between the upper pad ring and the lower pad ring. The diameter of the upper pad ring is larger than the diameter of the lower pad ring. Theumbrella waterproof pad is novel in structural design, is formed with an EPDM material (commonly known as plastic rubber) through injection molding and is smooth and uniform in outer surface, the dual-layer design is adopted, and the inner layer and the outer layer of the umbrella fabric are provided with the pad rings for protection. The contact faces of the pad rings and the umbrella fabric form two waterproof barriers and have a water seepage prevention effect. In assembly, people do not need to worry about the situation that the inner layer and the outer layer are not overlapped and the inner layer and the outer layer can be well attached when bolts are screwed down. No waterproof glue needs to be used when an umbrella is assembled, and the umbrella is rapid and convenient to assembleand attractive in appearance.

Description

technical field [0001] The invention relates to the technical field of outdoor products, in particular to an umbrella waterproof cushion. Background technique [0002] In the past, the waterproof rubber pads of umbrellas were generally made of rubber products. (The working environment and requirements are not high). The manufacturing process of rubber products is relatively simple, the mold is simpler than the injection mold, and the precision of the processed products is lower. The thickness of the rubber pad is a little uneven for a week. For other products, as long as there is enough force on the thread, it can be ignored, but the structure of the umbrella product itself cannot add a lot of force to the thread. Therefore, waterproof glue should be applied during assembly to solve the problem of water leakage. Contents of the invention [0003] In order to overcome the problems in the prior art, the invention provides an umbrella waterproof pad. [0004] The technical...
