DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a drainage tube arrangement and fixing device, including a base plate 1, an electric telescopic rod 2, a horizontal plate 3, a positioning groove 4, an upper guide tube 5, a protective washer 6, a horizontal threaded rod 7, a track window 8, a locking cap 9, a vertical plate 10, a limit window 11, a positioning bolt 12, a positioning nut 13, a lower guide tube 14 and an inner protection pad 15. The electric telescopic rods 2 are fixedly installed at both ends of the top surface of the base plate 1, and the top of the electric telescopic rod 2 is connected and fixed to the bottom surface of the horizontal plate 3. The horizontal plate 3 is provided with a positioning groove 4, and the upper guide tube 5 is installed through the positioning groove 4. The upper guide tube A protective washer 6 is fixedly installed at the top and bottom of the upper guide tube 5, a horizontal threaded rod 7 is fixedly installed on one side of the bottom end of the upper guide tube 5, the horizontal threaded rod 7 passes through a track window 8, the track window 8 is arranged at one side of the bottom of the positioning groove 4, a locking cap 9 is installed at the end of the horizontal threaded rod 7, a vertical plate 10 is fixed at the bottom of the bottom end of the upper guide tube 5, a limit window 11 is arranged on the vertical plate 10, a positioning bolt 12 is installed through the limit window 11, a positioning nut 13 is installed on the positioning bolt 12, a lower guide tube 14 is fixedly installed at the end of the positioning bolt 12, and an inner protective pad 15 is fixed on the inner wall of the lower guide tube 14.

[0021] The inner wall of the positioning groove 4 in this example fits tightly with the outer wall of the upper guide tube 5, and the front view cross-section of the positioning groove 4 and the front view cross-section of the upper guide tube 5 are both "L"-shaped. The above structural design ensures the stable installation of the upper guide tube 5 and enables the upper guide tube 5 to be stably displaced and adjusted along the inner side of the positioning groove 4.

[0022] The inner diameter of the protective gasket 6 is smaller than the inner wall diameter of the upper guide tube 5. Both ends of the upper guide tube 5 are away from the surface of the horizontal plate 3. The above structural design can avoid contact and friction between the drainage tube and the two ends of the upper guide tube 5 and the surface of the horizontal plate 3, ensuring smooth passage and movement of the drainage tube.

[0023] The horizontal threaded rod 7 is slidably connected to the track window 8, and the horizontal threaded rod 7 is threadedly connected to the locking cap 9. The front view shape of the locking cap 9 is a "T" shape. The above-mentioned structural design enables the horizontal threaded rod 7 to carry the upper guide tube 5 along the track window 8 for stable horizontal displacement sliding, and the locking cap 9 utilizes the threaded connection relationship with the horizontal threaded rod 7 to stably squeeze the horizontal plate 3, thereby quickly fixing the horizontal threaded rod 7 and the upper guide tube 5.

[0024] The positioning bolt 12 is slidably connected to the limit window 11. The centers of the positioning bolt 12, the limit window 11 and the upper guide tube 5 are on the same vertical plane. The above-mentioned structural design enables the lower guide tube 14 to slide vertically along the limit window 11 with the positioning bolt 12 to adjust the distance between the lower guide tube 14 and the upper guide tube 5.

[0025] The lower guide tube 14 is vertically arranged, and the center of the lower guide tube 14 and the center of the upper guide tube 5 are on the same vertical plane. The above structural design enables the lower guide tube 14 and the upper guide tube 5 to stably guide and remove the drainage tube, ensuring that the drainage tube can bend smoothly.

[0027] Then will Figure 2 The locking cap 9 in the middle is rotated away from the side of the horizontal plate 3, and the horizontal plate 3 is no longer squeezed to fix the position of the upper guide tube 5. The locking cap 9 is moved to slide the horizontal threaded rod 7 and the upper guide tube 5 along the positioning groove 4 horizontally until the spacing between different drainage tubes is appropriate. The locking cap 9 is rotated to return to squeeze the side of the horizontal plate 3 to fix the horizontal position of the upper guide tube 5.

[0028] Then rotate the positioning nut 13 away from the side of the vertical plate 10, no longer squeeze the vertical plate 10 to fix the height of the positioning bolt 12 and the lower guide tube 14, push the lower guide tube 14 with the positioning bolt 12 to slide vertically along the limit window 11 until the height of the lower guide tube 14 is appropriate, and the curvature of the drainage tube between the top of the lower guide tube 14 and the bottom of the upper guide tube 5 is smooth, rotate the positioning nut 13 to reset and squeeze the side of the vertical plate 10, fix the height of the lower guide tube 14, ensure that different drainage tubes are arranged independently, and ensure that pus, blood, and liquids with different viscosities in different drainage tubes can be discharged smoothly. This is the working principle of the drainage tube arrangement and fixing device.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
