Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 5, including controlling axial base 1, transmission groove 2 has coaxially been seted up in base 1, the coaxial rotation of 1 left end of base is connected with center post 3, 3 right-hand members of center post insert in transmission groove 2 and coaxial be equipped with wind spring 4, 4 free ends of wind spring are through connecting axle and base 1 fixed connection, axial through groove 5 about 3 middle parts of center post were seted up, the winding groove 6 that communicates and the screw thread shape with through groove 5 is seted up respectively to the left and right sides on 3 lateral walls of center post, the screw thread of two winding grooves 6 revolves to opposite, the coaxial dismantlement of 1 left end of base is connected with shell 7, link up around and the first standing groove 8 that the opening was right around having seted up on the lateral wall before shell 7, link up around and the second standing groove 9 that the opening was right after having seted up on.

In order to facilitate the rotation of the central column 3, a guide groove 10 with a leftward opening is coaxially formed in the central column 3, and a guide column 11 which can be inserted into the guide groove 10 and can move in the guide groove 10 is coaxially formed in the left side wall in the outer shell 7.

In order to limit the rotating position of the central column 3, a limiting groove 12 positioned at the right side of the transmission groove 2 is coaxially formed in the base 1, a ratchet wheel 13 is coaxially arranged when the right end of the central column 3 is inserted into the limiting groove 12, and a pawl 14 capable of being meshed with the ratchet wheel 13 is hinged to the left side wall of the limiting groove 12.

In order to make the pawl 14 engage with the ratchet wheel 13, an elastic piece 15 capable of contacting with the upper end surface of the pawl 14 is arranged in the limiting groove 12.

In order to facilitate the release of the engagement between the pawl 14 and the ratchet wheel 13, the right side wall of the limiting groove 12 is provided with a left-right through arc-shaped groove 16, and the pawl 14 is provided with a push rod 17, the right end of which extends out of the arc-shaped groove 16 and can move in the arc-shaped groove 16.

In order to enable the shell 7 to be detachably connected with the base 1, the upper side and the lower side of the base 1 are respectively provided with an arc-shaped plate 18 positioned at the left end of the base, the openings of the two arc-shaped plates 18 are opposite, the two arc-shaped plates 18 are respectively provided with an upper slot, a lower slot and a left slot, the upper slot and the lower slot are communicated, the left slot is provided with an opening, and the upper side and the lower side of the shell 7 are respectively provided with an insertion block 19 which can be inserted.

When the utility model is used, the medical staff moves the shell 7 leftwards to drive the plug block 19 to move leftwards, when the insert block 19 is moved out of the slot, the shell 7 is separated from the base 1, at the moment, the drainage tube passes through the through slot 5 and the device is positioned in the middle of the drainage tube, the front side of the drainage tube is clockwise rotated to be wound on the central column 3 along the winding slot 6 on the left side, meanwhile, the rear side of the drainage tube is clockwise rotated to be wound on the central column 3 along the winding groove 6 on the right side, after the drainage tube is wound to a proper length, the shell 7 is moved rightwards to enable the shell 7 to drive the plug block 19 to be inserted into the slot, when the right end face of the shell 7 is contacted with the left end face of the base 1, the shell 7 is stopped to move, simultaneously, in the moving process of the shell 7, the free end of the front side of the drainage tube is extended out of the first placing groove 8, the free end of the rear side of the drainage tube is extended out of the second placing groove 9, and the preparation stage is finished;

after the preparation stage is finished, if the extending length of the drainage tube needs to be extended, pulling the two free ends of the drainage tube outwards, enabling the two free ends to move outwards and simultaneously drive the central column 3 to rotate clockwise, enabling the central column 3 to drive the coil spring 4 to contract inwards, enabling the central column 3 to drive the ratchet 13 to rotate clockwise, enabling the ratchet 13 to push the pawl 14 to swing upwards and extrude the elastic sheet 15 along with the rotation of the ratchet 13, stopping pulling the drainage tube after the drainage tube is stretched to a proper length, enabling the pawl 14 to be meshed with the ratchet 13 under the action of the elastic sheet 15 at the moment, limiting the rotation of the ratchet 13, and limiting the stretched length of the drainage tube;

if the drawn drainage tube needs to be retracted, the push rod 17 is swung upwards to enable the push rod 17 to swing along the arc-shaped groove 16, meanwhile, the push rod 17 drives the pawl 14 to swing upwards and extrude the elastic piece 15, at the moment, the pawl 14 is separated from the ratchet wheel 13, the central column 3 rotates anticlockwise under the action of the coil spring 4 and drives the two ends of the drainage tube to be wound on the central column 3 again, after the drainage tube retracts to a proper length, the push rod 17 is loosened, the pawl 14 swings downwards under the action of the elastic piece 15 and is meshed with the ratchet wheel 13, at the moment, the position of the ratchet wheel 13 is limited, and the position of the central.

The utility model provides a drainage tube has certain hardness, can not produce the extrusion because of the pulling and block up.
