[0041] Embodiment:

[0042] Refer to Figures 1 to 7, an embodiment of the present utility model discloses a pipeline fixator, which includes a fixing structure 100, a cover body 200, a gauze layer 300, and a protective layer (not shown in the figure) for wrapping around the pipeline. The fixing structure 100 has a through installation cavity 110, and at least one side wall of the installation cavity 110 is provided with a protrusion. The protective layer is installed in the installation cavity 110, and the cooperation between the protective layer and the protrusion can enhance the stability of the protective layer, thereby preventing the pipeline from moving in the installation cavity 110. The gauze layer 300 is arranged at the bottom of the fixing structure 100, and the arrangement of the gauze layer 300 can prevent pressure sores. The cover body 200 is arranged on the top of the fixing structure 100, and the cover body 200 is mainly used to control the opening and closing of the installation cavity 110 for placing the pipeline.

[0043] The pipeline fixator disclosed in this embodiment can effectively increase the friction between the protective layer and the inner wall of the installation cavity 110 by setting protrusions, thereby enhancing the stability of the installation of the protective layer and the pipeline, and preventing the pipeline and the protective layer from sliding along the installation cavity 110.

[0044] Refer to Figure 1 and Figure 2 , the fixing structure 100 is provided with an installation cavity 110, the installation cavity 110 extends along the length direction of the fixing structure 100, and both ends of the installation cavity 110 extend to two opposite side walls of the fixing structure 100 respectively.

[0045] In this embodiment, the cross-section of the installation cavity 110 along the direction perpendicular to its extension direction can be made polygonal. For example, the cross-section of the installation cavity 110 can be made quadrilateral, pentagonal or hexagonal, etc. In this embodiment, the cross-section of the installation cavity 110 is set as a rectangle for illustration.

[0046] The installation cavity 110 includes at least one stabilizing wall 120, and at least one first protrusion 130 is arranged on the stabilizing wall 120. In this embodiment, both opposite side walls of the installation cavity 110 can be set as the stabilizing walls 120. Of course, this is only one implementation manner of this embodiment. In other embodiments, for example, when the installation cavity 110 is set in a shape such as a hexagon or an octagon, more groups of oppositely arranged stabilizing walls 120 can be arranged in the installation cavity 110 to enhance the stability of the pipeline installation.

[0047] A plurality of first protrusions 130 can be provided on each stabilizing wall 120. When there are multiple first protrusions 130, the multiple first protrusions 130 are arranged at intervals along the extending direction of the installation cavity 110, and the bottoms of adjacent first protrusions 130 are connected to each other so that the interface of the stabilizing wall 120 along the extending direction of the installation cavity 110 is curved. The curved shapes of the oppositely arranged stabilizing walls 120 are the same so that the two stabilizing walls 120 can fit together. In this way, all the first protrusions 130 can be staggered, so that the acting points of the first protrusions 130 on the protective layer are staggered. According to the mechanical principle, it is more stable than when the upper and lower acting points are consistent, which can further enhance the stability of the pipeline and thus prevent the pipeline from moving.

[0048] Refer to Figure 3 , the gauze layer 300 is arranged at the bottom of the fixing structure 100, and it can serve as the bottom wall of the installation cavity 110; the cover body 200 is arranged on the top of the fixing structure 100, and it can serve as the top wall of the installation cavity 110.

[0049] Refer to Figure 5 , on the side of the cover body 200 facing the installation cavity 110, a second protrusion 220 is provided. The cooperation between the second protrusion 220 and the first protrusion 130 can better fix the protective layer and the pipeline.

[0050] In this embodiment, the cover body 200 is rotatably connected to the fixing structure 100. The cover body 200 and the fixing structure 100 are connected by a hinge so that the cover body 200 can rotate relative to the fixing structure 100, and the rotation axis of the cover body 200 and the fixing structure 100 is parallel to the extending direction of the installation cavity 110, so as to open or close the installation cavity 110 along its extending direction when the cover body 200 moves, and it is convenient to take and place the pipeline at this time. Of course, making the cover body 200 rotatably connected to the fixing structure 100 is only one implementation manner in this embodiment. In other implementation manners, the cover body 200 and the fixing structure 100 can also be detachably matched.

The clamping block 140 is clamped with the card slot 210 to fix the cover body 200 and the fixing structure 100.

[0052] Specifically, refer to Figures 5 to 7, the card slot 210 includes a first slot 211 and a second slot 212. The first slot 211 and the second slot 212 are sequentially arranged along the width direction of the cover body 200, and the second slot 212 is connected to the side of the first slot 211 away from the installation cavity 110. The card block 140 includes a sliding portion 141, a connecting portion 142 and a clamping portion 143. The sliding portion 141 is slidably connected to the fixed structure 100, and one end of the sliding portion 141 extends outside the fixed structure 100. The clamping portion 143 is connected to the sliding portion 141 through the connecting portion 142, and the sliding portion 141 is slid to allow the clamping portion 143 to enter or leave the second slot 212. A spring member 150 is also provided on the fixed structure 100, and the two ends of the spring member 150 are respectively connected to the fixed structure 100 and the sliding portion 141, and the spring member 150 makes the clamping portion 143 have a tendency to move toward the second slot 212. The top of the clamping portion 143 is provided with an inclined surface, which is located at one end of the clamping portion 143 away from the spring member 150 . When the cover 200 is closed, the inclined surface can make the clamping portion 143 return to the range where the first groove 211 is located.
