Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0027] Embodiment

[0028] Please refer to Figures 1-4 As shown, the present invention provides the following technical solutions: A drainage tube stopper that is convenient to adjust, including a drainage tube 1, and a clamping sleeve 2 is sleeved on the outer side of the drainage tube 1; reference can be made to the attached Figure 1 and the attachedFigure 2 and appendix Figure 3 As shown, the clamping sleeve 2 includes a sleeve 21 and a connecting cylinder 22. The sleeve 21 is sleeved outside the drainage tube 1; an installation opening 214 is formed in the side wall of the sleeve 21. The installation opening 214 penetrates through the sleeve 21, and the size of the installation opening 214 is slightly smaller than that of the drainage tube 1, facilitating the clamping and limiting of the drainage tube 1; a pressing strip 211 is fixedly arranged in the middle of the inner wall of the sleeve 21, and the pressing strip 211 is located on one side of the drainage tube 1; the pressing strip 211 is made of a flexible material and is a horizontally placed arc-shaped strip, capable of supporting and pressing the drainage tube 1; a connecting cylinder 22 is connected and penetrated through the middle of the outer wall of the sleeve 21, and a clamping component 3 is inserted inside the connecting cylinder 22. The clamping component 3 includes a push-pull plate 31, a connecting rod 32, and a pressing plate 34. A connecting rod 32 is fixedly arranged on one side of the push-pull plate 31. The connecting rod 32 penetrates through the connecting cylinder 22, and a pressing plate 34 is fixedly arranged at one end of the connecting rod 32. The pressing plate 34 is located on the other side of the drainage tube 1; after the clamping sleeve 2 is sleeved outside the drainage tube 1 in this solution, when the drainage tube 1 needs to be clamped, the connecting rod 32 can be pushed, so that the pressing plate 34 presses and flattens the drainage tube 1 on the pressing strip 211, thereby realizing the clamping situation. The flexible material can avoid the situation that the drainage tube 1 is damaged by clamping.

[0029] Refer to Figure 3 and Figure 4 As shown, specifically, a moving opening 221 is formed in the middle of one side wall of the connecting cylinder 22, and docking grooves 222 are symmetrically formed on both sides of the moving opening 221. The connecting rod 32 penetrates through the moving opening 221; a docking plate 33 is fixedly arranged on the connecting rod 32. The docking plate 33 is located on one side of the push-pull plate 31. The docking plate 33 is perpendicular to the docking groove 222, and the size of the docking plate 33 is adapted to the size of the docking groove 222; a spring 223 is fixedly arranged on the inner side edge of the connecting cylinder 22. The spring 223 is located outside the connecting rod 32. One end of the spring 223 is fixedly connected with a connecting ring 224. A connecting ring 225 is fixedly arranged on one side wall of the connecting ring 224, and a limiting ring 226 is fixedly arranged on one side of the connecting ring 225; a limiting groove 35 is formed on the side wall edge of the pressing plate 34. The limiting ring 226 is clamped inside the limiting groove 35. When the pressing plate 34 rotates, it does not affect the pulling effect of the spring 223. When clamping the drainage tube 1, the connecting rod 32 is rotated so that the docking plate 33 is aligned with the docking groove 222 and then pushed, so that the docking plate 33 passes over the docking groove 222 and presses the drainage tube 1 tightly. After pressing, the connecting rod 32 is rotated again so that the docking plate 33 is perpendicular to the docking groove 222 from the inside for limiting, which can ensure the stability of clamping and is convenient to operate.

[0030] Refer to Figure 1 and Figure 2As shown, specifically, a first friction ring 212 is fixedly provided at the upper end of the inner wall of the sleeve 21, and a second friction ring 213 is fixedly provided at the lower end of the inner wall of the sleeve 21; both the first friction ring 212 and the second friction ring 213 are made of flexible materials; the friction rings made of flexible materials are used to increase the friction force between the drainage tube 1 and the clamping sleeve 2, thereby improving the installation stability of the clamping sleeve 2.

[0031] Referring to Figure 1 With Figure 2 As shown, specifically, a limiting arc plate 23 is fixedly provided on the outer wall of the sleeve 21. There are multiple limiting arc plates 23, and the limiting arc plates 23 are made of flexible materials; in this solution, when the drainage tube 1 needs to be bent and stored, the drainage tube 1 can be wound and clamped in an S shape on the inner side of the limiting arc plate 23, which is convenient for arrangement.

[0032] The working principle and usage process of the present utility model: When the patient uses the drainage tube 1, the clamping sleeve 2 is sleeved on the outer side of the drainage tube 1 through the installation opening 214 and is frictionally limited by the friction ring. When the patient needs to move or undergo an examination, the connecting rod 32 on the clamping sleeve 2 can be rotated, so that the docking plate 33 passes through the docking groove 222, and the pressing plate 34 presses the drainage tube 1 against the pressing strip 211 for clamping. Then, the connecting rod 32 is rotated to make the docking plate 33 perpendicular to the docking groove 222 for limiting, thereby realizing the stable clamping of the drainage rod 1. After the clamping is completed, the above operation is repeated to pull the connecting rod 32 outwards to cancel the clamping of the drainage tube 1. When the drainage tube 1 becomes flattened due to clamping and recovers slowly, the operator can rotate the clamping sleeve 2 by ninety degrees on the outer side of the drainage tube 1 and repeat the above clamping operation to push the drainage tube 1 to recover. The operation is convenient.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
