In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0024] In the present utility model, if Figure 1-2 As shown, a joint protective cover is provided, comprising a cover portion 1 and a barrel portion 2 connected to the cover portion 1, wherein the barrel portion 2 is elastically configured so that when the barrel portion 2 is sleeved on the end of a pipeline, the cover portion 1 can close the end of the pipeline; the cover portion 1 is recessed toward the barrel portion 2 to form an operating chamber 5.

[0025] like Figures 1 to 2 As shown, when the protective cover of the utility model is used, the barrel 2 is inserted into the joint position of the end of the pipeline 7. Since the barrel 2 is set as an elastic barrel 2, the barrel 2 can be tightly fixed on the pipeline 7, so that the protective cover can be stably fixed on the pipeline 7 and is not easy to fall off. The cover 1 is connected to the barrel 2, and the joint of the pipeline 7 can be sealed and protected after the protective cover is installed to prevent external dust and dirt from entering. In addition, the elastic barrel 2 can also form a buffer when the pipeline 7 is bumped during transportation, so as to reduce the possibility of damage to the joint of the pipeline 7 due to bumping.

[0026] like Figure 2As shown, by providing the operating cavity 5, when the operator is carrying the end of the pipeline 7, the operator can insert the hand into the operating cavity 5 to fix the end of the pipeline 7, which is convenient for operation. When the operator is carrying the pipeline 7, the operator can hold and fix the pipeline 7 with the hand inside the operating cavity 5 and outside the barrel 2, which can also improve the fixing stability of the protective cover on the pipeline 7, so as to prevent the protective cover from slipping off during the transportation of the pipeline 7.

[0027] In a preferred embodiment, for the structure of the utility model, more specifically, the cover portion 1 and the barrel portion 2 are integrally formed and connected, so as to facilitate the processing of the protective cover and improve the structural stability of the protective cover.

[0028] In a preferred embodiment, a further optimized configuration of the utility model is that, as shown in the figure, the cover portion 1 is formed with a boss 101 protruding from the barrel portion 2 .

[0029] By forming a boss 101 on the edge of the cover 1 , when the protective cover is removed from the pipeline 7 , the boss 101 can be used to hold and exert force to pull the protective cover outward.

[0030] In a preferred embodiment, the cover 1 and the barrel 2 are integrally formed so that the cover 1 can be made into an elastic cover 1, thereby further improving the protection effect on the pipeline 7 when a bump occurs at the joint of the pipeline 7.

[0031] In a preferred embodiment, for the structure of the utility model, more specifically, as shown in the figure, the radial dimension of the portion of the boss 101 protruding from the barrel 2 is greater than or equal to 0.5 mm and less than or equal to 5 mm.

[0032] In a preferred embodiment, for the structure of the present utility model, more specifically, as shown in the figure, the thickness of the boss 101 is greater than or equal to 1 mm and less than or equal to 8 mm.

[0034] In a preferred embodiment, for the structure of the utility model, more specifically, as shown in the figure, the inner surface of the cylinder 2 is provided with an inwardly convex arc rib 4. Figure 2 As shown, by providing the arc rib 4, when there are fixed structures such as bayonet and clamping platform at the joint of the pipeline 7, the arc rib 4 can be clamped at the position of this part of the fixed structure, so as to further improve the installation stability of the protective cover.

[0035] exist Figure 1In the embodiment shown, the structure of the protective cover is further described in detail, as shown in the figure, the cover 1 includes a bottom wall 103 and a side wall 102 connected to the bottom wall 103, the side wall 102 is cylindrical, and the axis of the side wall 102 is parallel to the axis of the cylinder 2. Figure 2 As shown, the side wall 102 is roughly cylindrical, so as to facilitate the operator to hold it.

[0036] In an optional embodiment, the structure of the operating chamber 5 may also be set in other forms, such as the operating chamber 5 is set in a cone shape as a whole.

[0037] exist Figure 1 In the illustrated embodiment, for the structure of the utility model, to be more specific, as shown in the figure, the bottom wall of the operating cavity is provided with a structural hole 6, and the cover 1 further includes an insert block 3 inserted in the structural hole 6.

[0038] like Figure 2 As shown, by providing a structural hole 6, in the embodiment where the cover 1 and the barrel 2 are integrally formed, it is convenient to demould the protective cover. In addition, by using the structural hole 6, in some embodiments, the inside and outside of the protective cover can also be connected through the structural hole 6 to maintain the balance of internal and external air pressure when the protective cover is pulled out and inserted, thereby reducing the difficulty of operation. By providing the plug block 3, the possibility of dust and dirt entering the structural hole 6 can be reduced when the protective cover is protected.

[0039] Regarding the specific forms of the plug block 3 and the structural hole 6, Figure 1 In the embodiment shown, further specifically, as Figure 2 As shown, the insert block 3 is configured to be columnar, and a slot is provided on the side of the insert block 3 so that the cover 1 can be snapped into the slot at the edge of the structural hole 6, thereby preventing the insert block 3 from being separated from the cover 1.

[0040] In a preferred embodiment, the structure of the utility model is further specifically described as follows: Figure 2 As shown, the thickness of the barrel portion 2 gradually decreases in a direction away from the cover portion 1 .

[0041] By such an arrangement, the deformation capability of the barrel portion 2 away from the cover portion 1 can be improved, so as to further facilitate the sleeve of the barrel portion 2 on the pipeline 7 .

[0042] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
