Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As Figure 1-4, the present embodiment disposable medical catheter gasbag pressure table, it comprises housing 1, joint 8, display panel 9, pointer 10, air bag 11 etc., housing 1 is oblate column, its inner cavity that forms, for assembling each parts, and cavity does not seal; The lateral wall of housing 1 forms one with externally threaded hollow small cylinder 1-1, and the cavity of the hollow bulb of right cylinder 1-1 and housing 1 connects.Right cylinder 1-1 built-in expansion air bag 11, one end 11-1 perforate of air bag 11, other end 11-2 is sealed.
By three root post 12,13,14 mounting brackets 2, rotating shaft 15 is passed the middle part of support 2 and is rotatably assorted in centre point of the interior end of housing 1, between rotating shaft 15 and support 2, is rotatably assorted at the interior end of housing 1.The outer affixed gear 3 of rotating shaft 15 between the interior end of housing 1 and support 2.
The other end of connecting rod 4-3 is by axle 16 actuator 7 that is rotatably assorted, and the other end of actuator 7 is touched in the outer end of air bag 11 11-2 outer wall.
The interior end of housing 1, fixedly mounts limited block 6 by screw.The middle part of column 14 overcoat torsion springs 5, one side of torsion spring 5 peaks at limited block 6, and another side peaks at connecting rod 4-2.
The inwall of housing 1 forms a ring-shaped step portion, and housing 1 packs circular display panel 9 into, and the edge of display panel 9 is held on the ring-shaped step portion of housing 1.Rotating shaft 15 through the center of circle of circular display panel 9, is fixedly connected with pointer 10 from inner side.The outside surface edge of display panel 9 indicates scale, and fixes a limited post 17 in 0 scale place.Add a cover a compacting ring in the outside of display panel 9, compacting ring is pressed on the edge of display panel 9, adds a cover a transparency cover outside compacting ring again, the opening part interlocking of this transparency cover and housing 1.
