The following specific embodiment will combine above-mentioned accompanying drawing to further specify the present invention.
The specific embodiment
See also Fig. 1, Fig. 2 and Fig. 3, a preferred embodiments of the barometric control unit of printer of the present invention comprises that a compression piece 11, is used for and the fixing regulating part of said compression piece 11 12, a flexible member 13, an air pressure valve 14, a packing ring 15 and an air pressure stream exchange device 16.
Said compression piece 11 comprises that connecting rod 112 that an installation portion 111, extends to form from said installation portion 111 and is from press section 113 that said connecting rod 112 extends to form.Said installation portion 111 is provided with four installing holes 1111, and said installation portion 111 is in the form of annular discs.Said press section 113 comprises that pushing body 1131 and pushes the location convex body 1132 that body 1131 extends to form from said.
Said regulating part 12 comprises that one regulates the fixed part 122 that body 121 reaches four corresponding said installing holes 1111 of difference that extend to form from said adjusting body 121.Said adjusting body 121 is cylindric, and said adjusting body 121 is provided with an endoporus 123, and said adjusting body 121 is provided with an internal thread 124 in said endoporus 123.
In the present embodiment, said flexible member 13 is a spring, and said flexible member 13 is provided with one around mouth 131.
Said air pressure valve 14 comprises a supporting part 141, and the endoporus 123 of the size of said supporting part 141 and said adjusting body 121 is roughly the same.
Said packing ring 15 is processed by elastomeric material in the form of a ring.
Said air pressure stream exchange device 16 comprises that a cavity 161, connects the air pressure input part 162 of said cavity 161 and the air pressure efferent 163 of the said cavity 161 of a connection.The outer wall of said cavity 161 convexes with external screw thread 1611, the inwall of said cavity 161 be provided with one be used to support said air pressure valve 14 support portion 1612, said support portion 1612 is ringwise.Said air pressure input part 162 is provided with an input port 1621, and said air pressure efferent 163 is provided with a delivery outlet 1631.Said input port 1621 is communicated with said delivery outlet 1631.
See also Fig. 1 to Fig. 4, during assembling, earlier said packing ring 15 is placed on the support portion 1612 of said cavity 161, then said air pressure valve 14 is placed on the said packing ring 15, more said flexible member 13 is placed on the supporting part 141 of said air pressure valve 14.The fixed part of the installing hole 1111 of said compression piece 11 and said regulating part 12 122 is corresponding and said installing hole 1111 is separately fixed at said fixed part 122, thus said compression piece 11 is fixed together with said regulating part 12.The internal thread 124 of said regulating part 12 is corresponding with the external screw thread 1611 of said cavity 161; Move down said regulating part 12 and make the said external screw thread 1611 of internal thread 124 contacts, and be rotated down said regulating part 12 until the said flexible member 13 of the press section of said compression piece 11 113 conflicts.At this moment, the body 1131 of pushing of the press section 113 of said compression piece 11 is pushed said flexible member 13, the location convex body 1132 of said press section 113 be in said flexible member 13 around in the mouth 131.Said flexible member 13 elasticity are conflicted and on the supporting part 141 of said air pressure valve 14, are made the said packing ring 15 of said supporting part 141 compressions, and said air pressure valve 14 makes said input port 1621 and said delivery outlet 1631 form unique path.Continue to be rotated down said regulating part 12; The decrement of said flexible member 13 increases and applies bigger external force to said air pressure valve 14, thereby said air pressure valve 14 continues the said packing ring 15 of compression the seal between said input port 1621 and the said delivery outlet 1631 is increased.
