Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is overall structure diagram of the present utility model.
Fig. 2 is the structural representation of movable block.
In figure：1st, the pump housing；2nd, barrier piece；3rd, pump head；4th, vacuum chamber；5th, stage clip；6th, extension spring；7th, movable block；8th, it is fixed
Seat；9th, roll wheel assembly；10th, supporting plate is reinforced；11st, breather check valve；12nd, outgassing nonreturn valve；13rd, seal washer.
Specific embodiment
As depicted in figs. 1 and 2, the utility model includes being provided with the pump housing 1 of cavity, breather check valve 11, outgassing nonreturn valve
12, the barrier piece 2 that is arranged in the cavity and the pump head 3 positioned at the top of barrier piece 2；Pump head 3 is connected with barrier piece 2, barrier piece 2
Cavity is separated to form vacuum chamber 4；Breather check valve 11 and outgassing nonreturn valve 12 are connected and positioned at true with vacuum chamber 4
The lower section of plenum chamber 4；Pump head 3 drives barrier piece 2 to pump；When barrier piece 2 is moved, the vacuum chamber 4
Volume increases or reduces：Wherein, when the volume of vacuum chamber 4 increases, gas is entered by breather check valve 11, works as vacuum chamber
Volume reduce when, gas is discharged by outgassing nonreturn valve 12.
Stage clip 5 is provided with vacuum chamber 4, one end of stage clip 5 is fixed on the inwall of vacuum chamber 4, the other end with every
Catch 2 is connected；Extension spring 6 is provided with the pump housing 1, one end of extension spring 6 is fixedly connected with the pump housing 1, and the other end is connected with barrier piece 2.
So, in the folding process of the pump head 3 promotion barrier piece 2 is pressed, stage clip 5 can be compressed, so that a upward power is produced, when
After unclamping the pump head 3, stage clip 5 can promote the barrier piece 2 to move up；At the same time, positioned at the also band of extension spring 6 of the both sides of pump head 3
Move the barrier piece 2 to move up, so that more convenient operation, time saving and energy saving.In order to balance in power, it is easy to fix, extension spring 6 is
Two, respectively positioned at the both sides of the end of pump head 3.
The utility model is provided with annular recess in the outside of the pump housing 1, and movable block 7 is provided with the outside of annular recess；It is living
