Abstract

A storage structure for fluid pumping device adapted for disposing on a fluid pumping device comprises: a ring body, sleeved onto the fluid pumping device; a plurality of storage portions, arranged around the ring body, each of the storage portions being adapted for a workpiece to removably connected.

Claims

1. A fluid pumping device having a storage structure, comprising:

a fluid pumping device, including a barrel and a pumping mechanism, the barrel having an opening, the pumping mechanism being adapted for communicating an interior of the barrel and exterior for pumping fluid;

a ring body, sleeved onto the fluid pumping device to surround the opening;

a plurality of storage portions, arranged around the ring body, each of the storage portions being adapted for a workpiece to removably connected;

wherein a plurality of protrusions are formed on an inner annular wall of the ring body, the protrusions are adapted for engaging with a plurality of recesses on the fluid pumping device;

each of the storage portions has an insertion hole for the workpiece to be removably inserted through;

a stepped face is radially formed in each of the insertion holes;

each of the storage portions is a seat protrudedly formed on a periphery of the ring body, the seat is formed with one of the insertion holes;

each of the storage portions has a shoulder portion around the insertion hole, the shoulder portion extends along a radial direction of the insertion hole;

the shoulder portion is connected to the ring body and expands toward the ring body;

the ring body is formed with a plurality of through holes, the through holes and the insertion holes are located at different positions along the radial direction of the ring body;

an inner diameter of each of the insertion holes is different from an inner diameter of each of the through holes;

the storage portions are arranged spacedly;

the through holes are arranged spacedly;

the ring body is formed with an expanded hole for being sleeved onto the barrel and a reduced hole.

2. The fluid pumping device having a storage structure of claim 1, wherein the ring body is a cover to cover the opening of the fluid pumping device.

3. The fluid pumping device having a storage structure of claim 1, wherein each of the storage portions has an insertion hole for the workpiece to be removably inserted through.

4. The fluid pumping device having a storage structure of claim 3, wherein a stepped face is radially formed in each of the insertion holes.

5. The fluid pumping device having a storage structure of claim 3, wherein each of the storage portions has a shoulder portion around the insertion hole, the shoulder portion extends along a radial direction of the insertion hole.

6. The fluid pumping device having a storage structure of claim 1, wherein each of the storage portions has an insertion hole, a plurality of through holes are formed on the ring body, the through holes and the insertion holes are located at different positions along a radial direction.

7. The fluid pumping device having a storage structure of claim 1, wherein the barrel further includes a main body and a collection container detachably disposed on the main body, the storage portions are arranged around the main body outside the main body.
