Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
In the present invention, when not doing contrary explanation, the nouns of locality be included in term such as " top, bottoms " only represents the orientation of this term under normal service condition, or being commonly called as those skilled in the art's understanding, and should not be considered as the restriction to this term.
See Fig. 1, the invention provides a kind of vacuum driving device, this vacuum driving device comprises housing 1, film sheet 2, drive link 3 and spring 4; Wherein, the edge of film sheet 2 to be fixed on housing 1 inwall and housing 1 internal cavities is divided into vacuum chamber and atmosphere chamber, the outer wall of vacuum chamber being formed with the vacuum interface 5 for being connected with vacuum source, the outer wall of atmosphere chamber being formed with the pore 6 for being connected with air; One end of drive link 3 is connected with equipment to be driven, and the other end is through a Joint adjacent with atmosphere chamber on housing 1 and film sheet 2; Spring 4 is arranged in vacuum chamber and one end is connected with film sheet 2, and the other end is connected with the inwall of vacuum chamber; The central axis of spring 4 and the axis coaxle of drive link 3.
By technique scheme, film sheet 2 is used to be divided into by housing 1 and the atmosphere chamber of air communication and the vacuum chamber that is connected with vacuum source by vacuum interface 5.When unlatching vacuum source is to when carrying out vacuum action in vacuum chamber, in atmosphere chamber under atmospheric effect, film sheet 2 moves towards vacuum chamber and drives in drive link 3 indentation atmosphere chamber, and now the movement of film sheet 2 is by spring 4 compressional deformation in vacuum chamber; When cutting off vacuum source, originally the spring 4 of generation deformation was extruded for restoring to the original state, give the rebounding force of film sheet 2 one towards atmosphere chamber to be extruded by film sheet 2 towards atmosphere chamber generation deformation, drive link 3 is also subjected to displacement the synchronous outside towards housing 1 simultaneously.Above-mentioned such process just can control standard-sized sheet or the full cut-off of air door or the water valve be connected with drive link 3 efficiently and easily, improves working efficiency.
In the present embodiment, in order to avoid opening vacuum source to when carrying out vacuum action in vacuum chamber, the direction of concentrating due to effect size and action direction and causing film sheet 2 to move towards vacuum chamber offsets, undesirable to the compression effectiveness of spring 4, preferably, the quantity of vacuum interface 5 is two and two vacuum interfaces 5 are separately positioned on top and the bottom of the outer wall of vacuum chamber.
At film sheet 2 in atmosphere chamber and vacuum chamber critical part move back and forth, in order to improve the stability of its motion, prevent film sheet 2 from disconnecting with the connection of drive link 3 or spring 4, preferably this vacuum driving device also comprises two pieces of fixed plates 7 and fastening piece 8, and film sheet 2 is folded between two pieces of fixed plates 7 and two pieces of fixed plates 7 are fixed by fastening piece 8; The other end of drive link 3 is arranged on wherein on a fixed plate 7, and another fixed plate 7 is connected with spring 4.
In addition, in order to reduce fixed plate 7 and fastening piece 8 installs after on the bubble-tight impact of vacuum chamber, preferably, fixed plate 7 and fastening piece 8 contacting point are laid with one deck sealer.
When this vacuum driving device is not installed or interim dismounting and change time, dust in air easily enters in atmosphere chamber or vacuum chamber from vacuum interface 5 or pore 6, long time integration is to follow-up use or clean all can make troubles, in order to avoid above-mentioned situation occurs, preferably, on vacuum interface 5 and pore 6, all blocking has dust cap.Like this, take off dust cap when vacuum driving device uses, from vacuum interface 5 or pore 6, the gas of turnover can hinder the dust in air to enter; After use terminates, dust cap is blocked again and just can prevent contamination by dust well.
Further; in order to improve dust cap and vacuum interface 5 and and pore 6 between sealability; when preventing this vacuum driving device slant setting simultaneously dust cap easily from pore landing lose protective action; preferably, the contact wall of dust cap and vacuum interface 5 and the contact wall of dust cap and pore 6 are equipped with seal ring.
Below the preferred embodiment of the present invention is described in detail by reference to the accompanying drawings; but; the present invention is not limited to the detail in above-mentioned mode of execution; within the scope of technical conceive of the present invention; can carry out multiple simple variant to technological scheme of the present invention, these simple variant all belong to protection scope of the present invention.
It should be noted that in addition, each concrete technical characteristics described in above-mentioned embodiment, in reconcilable situation, can be combined by any suitable mode, in order to avoid unnecessary repetition, the present invention illustrates no longer separately to various possible compound mode.
In addition, also can carry out combination in any between various different mode of execution of the present invention, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
