Description

Combined plastic cup Technical Field The utility model relates to a plastic cup, in particular to a combined plastic cup. Background At present, most of common plastic cups in the market adopt an integrated molding design, and the cup body capacity is fixed. In actual use, when a user needs to temporarily increase capacity, a great deal of inconvenience is often faced. If more guests visit and need to contain drinks, the existing single plastic cup cannot meet the capacity requirement, and additionally purchase a large-capacity cup, so that diversified use scenes of users are difficult to meet. It follows that the existing plastic cup technology has significant disadvantages in terms of convenience in increasing capacity. Disclosure of utility model In order to overcome the defects in the prior art, the utility model provides the combined plastic cup which has the beneficial effects that the capacity can be conveniently increased. A combined plastic cup comprises a cup body, wherein an inner conical surface is arranged on the inner side of the upper portion of the cup body, an outer conical surface is arranged on the outer side of the lower portion of a lengthened cylinder, and the inner conical surface of the cup body is in interference fit with the outer conical surface of the lengthened cylinder. The outer conical surface is provided with a sealing ring groove, and the sealing ring groove is sleeved with a sealing ring. The cup body is fixed with a fixed ring, the rubber ring is hung on the fixed ring, the lengthened cylinder cup body is fixed with a hook, and the upper part of the rubber ring can be hung on the hook. The width of the opening at the upper end of the hook is smaller than that of the opening at the lower end. The inner periphery of the lengthened cylinder is provided with a diversion trench. A baffle is arranged in the lengthened cylinder, and a plurality of strip holes are annularly formed in the baffle. The lower part of the inner side of the lengthened cylinder is fixedly provided with a flat rod, the flat rod is positioned at the lower side of the baffle, and the baffle is detachably connected in the lengthened cylinder. The middle part of the upper side of the partition board is fixed with a rotary head. The middle part of the lower side of the partition plate is fixedly provided with a threaded column, the middle part of the flat rod is provided with a threaded hole, and the threaded column is connected to the threaded hole through threads. The lower side middle part of baffle is fixed with the spliced pole, and the middle part of flat pole is provided with the jack, and spliced pole interference fit inserts on the jack. Drawings The utility model will be described in further detail with reference to the accompanying drawings and detailed description. FIG. 1 is a schematic view of a combined plastic cup; FIG. 2 is a schematic diagram of a combined plastic cup; FIG. 3 is a schematic diagram III of a combined plastic cup; FIG. 4 is a schematic view of a threaded post threaded onto a threaded hole in a flat bar; FIG. 5 is a schematic illustration of an insert post with an interference fit on a receptacle on a flat bar; In the figure, a cup body 1, an inner conical surface 2, an outer conical surface 3, an extension cylinder 4, a sealing ring groove 5, a hook 6, a rubber ring 7, a fixing ring 8, a diversion trench 9, a strip hole 10, a baffle 11, a rotary head 12, a flat rod 13, a threaded column 14 and an inserting column 15. Detailed Description As shown in fig. 1; the combined plastic cup comprises a cup body 1, wherein an inner conical surface 2 is arranged on the inner side of the upper part of the cup body 1, an outer conical surface 3 is arranged on the outer side of the lower part of the lengthened cylinder 4, and the inner conical surface 2 of the cup body 1 is in interference fit with the outer conical surface 3 of the lengthened cylinder 4; When the user needs to increase the capacity of the plastic cup, the lengthened cylinder 4 is lifted up and aligned to the opening of the cup body 1, and as the inner conical surface 2 at the inner side of the upper part of the cup body 1 and the outer conical surface 3 at the outer side of the lower part of the lengthened cylinder 4 have complementary conical degrees, the lengthened cylinder 4 is slowly pressed down, and the two conical surfaces start to contact.
