Comprises a cylinder body, a piston which can move up and down in the cylinder body, a piston rod fixed with the piston, a handle fixed with the piston rod and an inflation assembly connected with a micro body. When the handle pulls the piston upwards through the piston rod, the volume of air below the piston is increased, the pressure intensity is reduced, and the air above the piston is extruded to the lower part from the periphery of the piston; when the handle presses the piston downwards through the piston rod, the volume of air below the piston is reduced, the pressure intensity is increased, the piston is tightly pressed against the cylinder wall, air is prevented from leaking above the piston, the piston is continuously pressed downwards, when the air pressure is strong enough to jack the valve inside of the tire, compressed air enters the tire, and meanwhile, air outside the cylinder enters the upper part of the piston from a gap at the upper end of the cylinder. Has the characteristics of simple structure, convenient use, long service life and the like. However, when the hand inflator is packaged, transported and stored, the handle is fixedly arranged on the piston rod and can be disassembled by using a tool, the product packaging volume is large, and the occupied transportation and storage space is large, so that the packaging cost and the transportation cost are high, and the storage is inconvenient. Aiming at the problems, many manufacturers and acquaintances develop and develop the products, but no ideal products are seen.
Disclosure of Invention
In order to overcome the defects existing in the prior art, the utility model aims to provide a quick-release handle of a hand inflator, which has the advantages of simple and reasonable structure, convenient operation and use, high disassembly speed, good use effect and low packaging and transportation cost.
The utility model provides a technical scheme that above-mentioned technical problem adopted, it includes handle, quick detach connects, piston rod, the handle on be equipped with the mounting hole, be equipped with in the mounting hole from the guide way that extends upwards and the card hole that meets with guide way upper portion, be equipped with positioning groove in the card hole, still be equipped with the pressure-bearing step in the mounting hole, quick detach connects by handle connecting portion, piston rod connecting portion and lie in between handle connecting portion and the piston rod connecting portion and with the bearing ring of pressure-bearing step complex and constitute, be equipped with the fixture block with card hole matched with on the handle connecting portion, be equipped with the protruding muscle of location with positioning groove complex on the fixture block; when the handle is pressed down, the pressure is transferred to the piston rod through the quick-release connector by the matching of the pressure-bearing step and the pressure-bearing ring, and when the handle is pulled up, the pulling force is transferred to the piston rod through the quick-release connector by the matching of the clamping hole and the clamping block.
The utility model discloses a further scheme, the pressure-bearing ring on be equipped with fixed slot, the piston rod cup joints on the piston rod connecting portion and plug in fixed slot.
After adopting above-mentioned structure, compare with prior art and have following advantage and effect: when the handle pushes down, the pressure which is greater than 1500N can be transmitted to the piston rod through the quick-release connector by the cooperation of the pressure bearing step and the pressure bearing ring, and when the handle is pulled upwards, the pulling force which is greater than 1000N can be transmitted to the piston rod through the quick-release connector by the cooperation of the clamping hole and the clamping block, so that the requirement of relevant standards is completely met. Secondly, simple structure, it is convenient to dismantle, and packing, transportation and storage are small, can significantly reduce packing, transportation and storage cost.
