Embodiment
For understanding in detail this novel technical characteristics and practical effect, and can realize according to the content of specification, further, with the preferred embodiment as shown in graphic, be described in detail as follows:
Preferred embodiment of drawing the pump of inflating on a kind of provided by the utility model, as shown in Figures 1 to 7, it comprises: a pump body 10, a pull bar 20, a piston apparatus 30, an end cylinder 40 and are trampled the elements such as rope 50, wherein:
These pump body 10 inside are for hollow and be provided with a top, a bottom, an air outlet hole 11 and more than one inlet hole 12, and this air outlet hole 11 runs through the top of this pump body 10, and this at least one inlet hole 12 runs through the bottom of this pump body 10.Preferably, this pump body 10 is provided with four inlet holes 12.As long as the utility model has at least one inlet hole 12 to act on, therefore the utility model is not done specific restriction for the quantity of inlet hole 12.
Preferably, this pump body 10 comprises that a cylindrical shell 10A and is in conjunction with mouth 10B, and this is screwed in the end face of this cylindrical shell 10A in conjunction with mouth 10B, and this air outlet hole 11 is positioned at this in conjunction with mouth 10B and axially runs through this in conjunction with mouth 10B.
This pull bar 20 is axially located in this pump body 10 and can moves axially along this pump body 10, wherein, this pull bar 20 is provided with a top and a bottom, the top axle of this pull bar 20 differs from the position of this air outlet hole 11 to the top of running through this pump body 10, the top of this pull bar 20 is positioned at outside this pump body 10, and the bottom of this pull bar 20 is positioned at this pump body 10.
This piston apparatus 30 is positioned at this pump body 10 and comprises a block 31, a valve member 32 and a sealing gland ring 33, this block 31 sets firmly the bottom that is combined in this pull bar 20, this block 31 is provided with an end face and a perforation 311, the end face of this block 31 is towards the top of this pull bar 20, this perforation 311 runs through this block 31 and differs from the position of this pull bar 20, and this perforation 311 is parallel to the axis of this block 31; This valve member 32 is hubbed on the end face of this block 31 and can seals the opening of this perforation 311; This sealing gland ring 33 is set in the outer circumferential face of this block 31 and is tight against the inner peripheral surface at this pump body 10.Sealing gland ring 33 is set in block 31 and conventionally knows the knowledgeable's technological means to understand for having in affiliated technical field, and the utility model is not described in detail at this.
