A plug-in structural air cylinder

Abstract

The invention discloses an inflator of an inserting structure. The inflator comprises an outer tube, a bottom cover, a sealing plug, a piston, a tubular piston rod, a handle, a bending connector, a rubber ball, an air belt connector, a lock wire, an air belt, a charging connector and a base, wherein the bottom cover is arranged on an upper end opening of the outer tube in an inserted manner, the sealing plug is inserted in a lower end opening of the outer tube, the piston is composed of a piston base arranged in the outer tube and a piston rubber cup, the handle is inserted to the upper end of the tubular piston rod, and the air belt connector is connected with the air belt. The inflator is simple in structure, and few parts and few sealing pieces are adopted; and except that threaded connection is adopted in the combination of the lock wire and a vertical head of the bending connector, and welding is adopted in the combination of the outer tube and the base, inserting connection is adopted in the combination of the other components. The design and manufacturing process is simple, assembling and combining are fast, easy and convenient, and large-scale assembly line type production is facilitated; and production efficiency is high, environmental protection is facilitated, the production cost can be reduced, and product quality can be guaranteed.

Description

technical field [0001] The invention relates to a manual gas cylinder, in particular to a plug-in structural gas cylinder. Background technique [0002] Inflators are mainly used to inject or replenish air for various tires and some balloon items, especially manual inflators. Combination of connection, bonding or welding, screw connection is relatively complex and cumbersome in the actual design, manufacture and assembly process; adhesive connection is inefficient in actual production, and it is very easy to be damaged by adhesive in the production process. Pollution affects the appearance quality of the product. In addition, the adhesive is not environmentally friendly and damages the health of the operator; the welding connection has high technical requirements for the operator, and because the quality of the welding is directly related to the air tightness of the gas cylinder, the welding efficiency Very low, so the production cost of the welded connection is relatively ...

[0002] Inflators are mainly used to inject or replenish air for various tires and some balloon items, especially manual inflators. Combination of connection, bonding or welding, screw connection is relatively complex and cumbersome in the actual design, manufacture and assembly process; adhesive connection is inefficient in actual production, and it is very easy to be damaged by adhesive in the production process. Pollution affects the appearance quality of the product. In addition, the adhesive is not environmentally friendly and damages the health of the operator; the welding connection has high technical requirements for the operator, and because the quality of the welding is directly related to the air tightness of the gas cylinder, the welding efficiency Very low, resulting in higher production costs for welded connections

These deficiencies in the prior art have seriously hindered the reduction of inflator production costs and the development of enterprises at present
