DETAILED DESCRIPTION

[0021] The technical scheme of the utility model embodiment will be described below with reference to the drawings.

[0022] Various pipes are installed in the aircraft for various purposes, and the pipes are used to transport lubricating oil and other substances to achieve various specific functions. In the related art, when the pipes are painted, the end of the pipe needs to be protected by a protective sleeve so that the end of the pipe is not invaded by paint and other undesirable substances. As shown in Figure 1 , a pipe protective sleeve is used when the pipe is painted. The specific use method is as follows: before the pipe is painted, the pipe protective sleeve is sleeved on the end of the pipe, and after the painting is completed, the pipe protective sleeve is removed from the end of the pipe. The existing technology has the disadvantage that during the painting process, the pipe protective sleeve is inevitably contaminated with paint, and when the pipe protective sleeve is removed from the pipe, the paint on the outside of the pipe protective sleeve may fall off and fall on the end of the pipe protected by the pipe protective sleeve, thereby causing contamination of the end of the pipe. Therefore, the technology needs to be improved to further improve the protection of the end of the pipe.

[0023] As shown in Figures 2 to 4 , the protective cover provided by the present application can be used to wrap the pipe protective sleeve as shown in Figure 1 . The protective cover includes a first edge 4 and a second edge 5, and the side surfaces of the first edge 4 and the second edge 5 are arc-shaped. When the two sides of the first edge 4 and the second edge 5 are in contact in the circumferential direction, a cylindrical structure is formed to surround the pipe protective sleeve. One end of the first edge 4 is provided with a first semicircular groove 11, and one end of the second edge 5 is provided with a second semicircular groove 12. When the first edge 4 and the second edge 5 are connected, the first semicircular groove 11 and the second semicircular groove 12 are spliced to form a circular opening. The position of the circular opening corresponds to the position of the necked portion 3 of the pipe protective sleeve in the figure. The side surface of the end of the first edge 4 away from the circular opening is provided with a first notch 13, and the side surface of the end of the second edge 5 away from the opening is provided with a second notch 14. The first notch 13 and the second notch 14 are the same in shape and size. When the two side surfaces of the first edge 4 and the second edge 5 are in contact, the first notch 13 and the second notch 14 are connected to form a notch. The notch corresponds to Figure 1 the position of the first ear 1 in the figure, and is used to expose the first ear 1 outside the protective cover through the notch. The end of the first edge 4 is provided with a first groove 15 connected to the first notch 13, and the end of the second edge 5 is provided with a second groove 16 connected to the second notch 14. When the two side surfaces of the first edge 4 and the second edge 5 are in contact, the first groove 15 and the second groove 16 are connected. The first groove 15 and the second groove 16 are spliced to form a groove. When Figure 1 the first ear 1 of the pipe sleeve in the figure is hung with a label, the groove can avoid the hanging rope of the label.

[0024] The side surface of the first edge 4 is integrally formed with a second ear 17, which can be used to hang a label, a sticker, etc.

[0025] The first edge 4 has a flange 18 integrally formed on the side facing the second edge 5, and the second edge 5 has a concave flange 19 integrally formed on the side facing the first edge 4, which mates with the flange 18. When the flange 18 and the concave flange 19 mate, the sealing performance between the first edge 4 and the second edge 5 can be improved.

[0026] The first edge band 4 has a first groove 20 on its side, and the second edge band 5 has a second groove 21 on its side. The first groove 20 and the second groove 21 abut against each other to form an annular groove, which is used to accommodate... Figure 1 Flange 18 of the middle guide tube protective sleeve.

[0027] A clamping mechanism is provided between the first edge 4 and the second edge 5. The clamping mechanism includes two clamping arms 6, which are integrally connected to the first edge 4 and the second edge 5, respectively. The two clamping arms 6 are symmetrically arranged, and protrusions 7 are integrally formed on opposite sides of each clamping arm 6. The two protrusions 7 are spaced apart on one clamping arm 6, and the protrusions 7 on the two clamping arms 6 are at different heights in the height direction of the clamping arm 6, thereby preventing interference between the protrusions 7 on the two clamping arms 6. A rotating rod 8 is threaded through the protrusions 7 of the clamping arm 6, allowing the clamping arm 6 to rotate about the rotating rod 8 as a center. A sleeve is fitted on the rotating rod 8... Figure 5 The torsion spring 9 shown has two leads at its ends abutting against the opposite sides of the two clamping arms 6. The opposite sides of the two clamping arms 6 have grooves 10, within which the leads of the torsion spring 9 slide. The grooves 10 limit the left and right movement of the leads, preventing axial movement of the torsion spring 9 on the rotating rod 8. When the torsion spring 9 twists, the leads slide within the grooves 10. The torsion spring 9 provides force to the clamping arms 6 to press the first edge 4 and the second edge 5 together. In their natural state, the first edge 4 and the second edge 5 form a cylindrical shape with one open end. When a hand presses the ends of the clamping arms 6 away from the first edge 4 and the second edge 5, bringing them closer together, the first edge 4 and the second edge 5 rotate and open, allowing the clamping arms to be inserted. Figure 1 The catheter protective sleeve is shown. In this embodiment, the clamping arms 6 are structures of the same shape and size. The clamping arms 6 can also be structures of different lengths and sizes, as long as relative rotation is achieved. In other embodiments, the elastic force provided by the torsion spring 9 between the two clamping arms 6 can be replaced by an elastic structure such as a spring sheet. The clamping mechanism can also be implemented by other structures that can achieve the same function as in this embodiment. For example, the two clamping arms 6 can also be a structure that crosses each other.

[0028] In this application, the shape of the protective cover is primarily designed to fit snugly against the outer wall of the catheter protective sleeve. When the shape of the corresponding catheter protective sleeve differs, the shape of the protective cover will also be adapted accordingly. With the inner wall of the protective cover fitting snugly against the outer wall of the catheter protective sleeve, paint is less likely to enter the gap between the protective cover and the catheter protective sleeve through any openings. In another embodiment, the inner wall of the protective cover may not fit snugly against the outer wall of the catheter protective sleeve, and the first notch 13, the second notch 14, the first groove 15, and the second groove 16 may not be provided. This would close the inner wall of the protective cover except for the openings. While this would also enclose the catheter protective sleeve, the label would be hidden inside the catheter protective sleeve, making marking difficult or requiring additional methods.
