Main shaft of the present invention can rotate by the relative fixed seat; The conversion adapter that promptly is connected with main shaft can rotate by the relative fixed seat; Solved in the existing technology conversion adapter all towards the defective of a fixed-direction, reached and save the space, ensure that air-flow is unobstructed and prolong the main shaft effect in working life.
Description of drawings
Fig. 1 is the sectional view of fluid conveying device in the embodiment of the invention.
The realization of the object of the invention, functional characteristics and advantage will combine embodiment, further specify with reference to accompanying drawing.
Embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
With reference to Fig. 1, Fig. 1 is the sectional view of fluid conveying device in the embodiment of the invention.As shown in Figure 1, fluid conveying device of the present invention comprises conversion adapter 1, hollow main shaft 2 and fixed base 3.One end of main shaft 2 is connected with conversion adapter 1, and the other end and fixed base 3 are rotationally connected, but 3 rotations of main shaft 2 relative fixed seats, and fluid flows in the fixed base 3 with main shaft 2 through conversion adapter 1 and is utilized.
Main shaft 2 of the present invention can rotate by relative fixed seat 3; The conversion adapter 1 that promptly is connected with main shaft 2 can rotate by relative fixed seat 3; Solved in the existing technology conversion adapter 1 all towards the defective of a fixed-direction, reached and save the space, ensure that air-flow is unobstructed and prolong the main shaft effect in working life.
In specific embodiment, conversion adapter 1 is fixedly connected on the main shaft 2.The angle that conversion adapter 1 and main shaft 2 form can be arbitrarily angled for 90 ° or other.
In specific embodiment; Main shaft 2 is provided with at least one groove 21 with the part that fixed base 3 is rotationally connected; Be provided with Sealing 5 in the groove 21, Sealing 5 is any in seal ring, packing, mechanical seal, oil sealing, water seal, sealed bolster plate, sealer and the soft packing.Certainly in specific embodiment, this mechanical seal mode can be substituted by the oil sealing mode.
Consider main shaft 2 relative fixed seat 3 rotations when needed; So the outer surface at main shaft 2 is provided with the grip part; The shape of grip part can be slided when gripping main shaft 2 in order to prevent hand for being easy to the arbitrary shape of held, and the surface of grip part is provided with more coarsely.
In specific embodiment, main shaft 2 is provided with flange 22 near a side of fixed base 3, and flange 22 restriction main shafts 2 and the length that fixed base 3 is connected prevent that the attachment portion of main shaft 2 and fixed base is long or too short.
In specific embodiment; Fixed base 3 is a metalwork with main shaft 2, between fixed base 3 and flange 22, resilient metal member 6 is set, and fluid conveying device also comprises clamp device 4; Clamp device 4 one ends and fixed base 3 are through being threaded; The other end crush ribs 21 is away from a side of resilient metal member 6, and when tightening clamp device 4, clamp device acts on flange 21 makes main shaft 2 move axially to the direction of fixed base 3.The reason that resilient metal member 6 is set is in medical device product; Main shaft 2 is metalwork with fixed base 3, and all needs ground connection, and fixed base 3 is connected with ground in the prior art; Resilient metal member 6 is arranged on the effect that main shaft 2 and fixed base 3 play conduction, guarantees that main shaft 2 is connected with ground.Another effect of resilient metal member 6 is: regulate the size of rotary main shaft 2 required power, when tightening clamp device 4, clamp device acts on flange 21 makes main shaft 2 move axially to the direction of fixed base 3, and the required power of rotary main shaft 2 is relatively large at this moment; When unscrewing clamp device 4, the required power of rotary main shaft 2 this moment is less relatively.
In specific embodiment; Clamp device 4 comprises joint 41 and vertical joint 41 extended press sections 42; Joint 41 is provided with internal thread and axial pass trough, and fixed base 3 is provided with and adaptive outside thread of internal thread and the tapped hole that cooperates with axial pass trough, when fixed base 3 and clamp device 4 through outside thread with after internal thread is connected; It is fixing with clamp device 4 with fixed base 3 again screw 8 to be passed groove and tapped hole, and press section 42 is arranged on the side of flange 22 away from resilient metal member 6.When 3 rotations of main shaft 2 relative fixed seats, screw 8 passes groove and tapped hole rotates fixed base 3 and the clamp device 4 fixing main shaft 2 drive fixed bases 3 that can prevent.
In specific embodiment, be provided with damping piece 7 between press section 42 and the flange 22, this damping piece 7 can be spring or rubber bush, its effect is the size of regulating rotary main shaft 2 required power.
More than be merely the preferred embodiments of the present invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
