Specific implementation mode
Embodiment one
Referring to fig. 1 to fig. 5, the connection structure of a kind of manual pumping and bellows of the utility model, the hand
Dynamic pumping 100 includes the pump housing 110 and shaft core 120, and shaft core 120 can move up and down realization with respect to the pump housing 110 and inflate.Shaft core
120 top is equipped with a pair of of handle 140 and a pair of of gas nozzle 130, reports to the leadship after accomplishing a task setting in cross.Further include that corresponding two gas nozzles 130 are set
Two connectors 200 set, the structure of connector 200 in a tubular form.The connector 200 is used to connect bellows and the gas nozzle 130,
Bellows entangles 200 first half 230 of connector, and 200 first half of the connector, 230 outer surface is equipped with and the bellows
The screw thread 231 of contact, wherein bellows are not drawn into.200 latter half 210 of connector can be plugged in together with the gas nozzle 130,
The fastening structure that can mutually snap together is equipped between the connector 200 and the gas nozzle 130.
The fastening structure includes the pillar 211 being arranged on 200 outer surface of the connector and is arranged in the gas nozzle 130
On card slot 131, which can be plugged into the gas nozzle 130, by rotating the connector 200
The pillar 211 can be made to be interlockingly connected or detach with the card slot 131.
The pillar 211 is two, is located on the outer circumference surface of the connector 200, is symmetric；It is corresponding described
Card slot 131 is two, is located on the outer circumference surface of the gas nozzle 130, is symmetric.The card slot 131 is L-shaped, including axis
Opening, institute are formed on the end face of the gas nozzle 130 to part 131-1 and circumferential portion 131-2, the axial component 131-1
Pillar 211 is stated to enter in the card slot 131 along the opening.The gas nozzle 130 is in axial component 131-1 and circumferential portion
The position that 131-2 is connected is equipped with an elastic blocking arm 132, and the elasticity blocking arm 132 is towards circumferential portion 131-2 internal stretches
A top ligule is formed, under buckle state, pillar 211 deducts described convex in the ends circumferential portion 131-2, the elasticity blocking arm 132
Column 211 prevents the pillar 211 from exiting circumferential portion 131-2.The elasticity blocking arm 132 is equipped with a button 132-1, stirs
