Abstract
The invention discloses a bicycle saddle and a machining method of a cover leather thereof. The machining method comprises the following steps: (a) plastic is molten; (b) the plastic in a molten state is injected in an injection mold; and air is blown into the mold for foaming in the mold injecting process; and (c) the demolding is performed after cooling formation. The saddle is higher in elasticity after being provided with the cover leather, so that people feel comfortable when sitting on the saddle; and the cover leather is higher in wear resistance, so that the saddle can be stably used for a long time.
Description
technical field [0001] The invention relates to bicycle accessories, in particular to a processing method for a bicycle seat cushion and its sheath. Background technique [0002] The function of the bicycle saddle is to make the rider's weight easy to pedal the bicycle at the same time. When the rider is riding, the buttocks are in contact with the seat cushion. In order to keep the rider comfortable and stable during riding, the seat cushion is usually relatively elastic. [0003] The patent of notification number CN1221377A discloses a bicycle seat cushion, which discloses a structure of a bicycle seat cushion. The seat cushion has a liner or cover structure, and the liner or cover structure includes: an inner layer made of elastic material, A foam or sponge material, and an outer skin. The elastic material is polyurethane, and the outer skin is made of leather or plastic material. It can be seen that the inner layer made of a softer material such as polyurethane can pr...
