Description

Technical Field

[0001] This utility model relates to the field of pipe fitting processing, and in particular to a protective cover. Background Technology

[0002] Aircraft are equipped with conduits for various purposes, through which substances such as lubricating oil are transported to achieve various specific functions. In related technologies, when painting the conduit diameter, it is necessary to protect the conduit end by covering it with a protective sleeve, so that the conduit end is not invaded by paint or other defective substances, and is also protected from defective substances during the baking process and transportation, thus protecting the conduit end.

[0003] like Figure 1 The diagram shows a schematic of a conduit protective sleeve. Although the sleeve protects the end of the conduit, paint may get on the outside of the sleeve after the conduit is painted. When the sleeve is removed, the paint may fall onto the end of the conduit, thus contaminating the end. Therefore, further improvements are needed to prevent paint from falling onto the end of the conduit when the sleeve is removed.

[0004] In existing technologies, such as Figure 2 As shown, after the conduit is painted, to prevent paint from falling into the conduit end when the conduit protective sleeve is removed, a protective cover exists, including a first edge, a second edge, and a clamping mechanism. The first and second edges can wrap around the conduit protective sleeve, thereby reducing paint adhesion to the surface of the conduit protective sleeve. However, this type of cover has a... Figure 1 The first lug has a notch, so during the painting process, paint will get on the first lug and flow through the notch to the first and second edging, causing the first and second edging to be contaminated with paint, which is not conducive to the repeated use of the conduit protective sleeve. Utility Model Content

[0005] The purpose of this invention is to provide a protective cover that allows the catheter protective sleeve to be reused multiple times.

[0006] The above-mentioned objective of this utility model is achieved through the following technical solution:

[0007] A protective cover includes a first edge and a second edge, the two sides of the first edge and the second edge can abut against each other to form a cylindrical shape with one end open. A clamping mechanism is provided between the first edge and the second edge, the clamping mechanism is used to drive the two sides of the first edge and the second edge that can abut against each other to press against each other. The side of the first edge has a first half-protrusion, and the side of the second edge has a second half-protrusion. When the two sides of the first edge and the second edge abut against each other to form a cylindrical shape, the first half-protrusion and the second half-protrusion abut against each other to form a protrusion.

[0008] Furthermore, the first half-protrusion is provided with a first half-notch, and the second half-protrusion is provided with a second half-notch. When the two sides of the first first edge and the second edge abut against each other to form a cylindrical shape, the first half-notch and the second half-notch form a gap.

[0009] Furthermore, the clamping mechanism includes two clamping arms, which are respectively connected to the first edge and the second edge. The clamping arms are symmetrically arranged, and protrusions are provided at intervals on the opposite sides of the two clamping arms. A rotating rod passes through the protrusions of the two clamping arms, and a torsion spring is sleeved on the rotating rod. The two pins of the torsion spring abut against the two clamping arms respectively.

[0010] Furthermore, the clamping arm is provided with a groove to accommodate the pin.

[0011] Furthermore, one end of the first edge is provided with a first semi-circular arc groove, and one end of the second edge is provided with a second semi-circular arc groove. When the two sides of the first edge and the second edge abut against each other, the first semi-circular arc groove and the second semi-circular arc groove are joined together to form a circular opening.

[0012] Furthermore, a second hanging ear is provided on the side of the first edge banding.

[0013] Furthermore, the first edge has a flange on the side facing the second edge, and the second edge has a recessed flange on the side facing the first edge that mates with the flange.

[0014] Furthermore, the first edge has a first groove on its side and the second edge has a second groove on its side, and the first groove and the second groove abut against each other to form an annular groove. Attached Figure Description

[0022] The technical solutions of the embodiments of this utility model will now be described with reference to the accompanying drawings.

[0023] Aircraft are equipped with various conduits for transporting substances such as lubricating oil to achieve specific functions. In related technologies, when painting these conduits, the ends need to be protected by covering them with protective sleeves to prevent paint or other contaminants from entering. Figure 1 The image shows an existing conduit protective sleeve used during conduit painting. The specific method of use is as follows: before painting, the protective sleeve is placed over the end of the conduit; after painting, the protective sleeve is removed from the end of the conduit. A drawback of this existing technology is that during the painting process, the outside of the protective sleeve inevitably becomes contaminated with paint. When the protective sleeve is removed from the conduit, the paint on the outside of the sleeve may flake off and fall onto the end of the conduit it protects, causing contamination. Therefore, this technology needs to be improved to further enhance the protective effect on the conduit end.

[0024] In existing technologies, such as Figure 2 As shown, after the conduit is painted, to prevent paint from falling into the conduit end when the conduit protective sleeve is removed, a protective cover is provided, including a first edge 4, a second edge 5, and a clamping mechanism. The first edge 4 and the second edge 5 can wrap the conduit protective sleeve within them, thereby reducing paint adhesion to the surface of the conduit protective sleeve. However, this protective cover has a... Figure 1 The first lug 1 has a notch, so during the painting process, paint will get on the first lug 1 and flow into the first edge 4 and the second edge 5 through the notch, causing the first edge 4 and the second edge 5 to be contaminated with paint, which is not conducive to the repeated use of the conduit protective sleeve.

[0025] like Figures 3 to 6 As shown, this application provides a protective cover that can be used to wrap around objects such as... Figure 1The protective sleeve for the catheter shown is surrounded by a first edging 4 and a second edging 5. The sides of both edging 4 and 5 are arc-shaped. When the first edging 4 and the second edging 5 abut against each other circumferentially, they form a cylindrical structure to enclose the catheter protective sleeve. One end of the first edging 4 has a first semi-circular groove 11, and one end of the second edging 5 has a second semi-circular groove 12. When the first edging 4 and the second edging 5 are connected, the first semi-circular groove 11 and the second semi-circular groove 12 join to form a circular opening. This circular opening corresponds to the constriction 3 position of the catheter protective sleeve in the figure.

[0026] The first edging 4 has a first semi-protrusion 13 on one side, and the second edging 5 has a second semi-protrusion 14 on one side. When the two sides of the first edging 4 and the second edging 5 abut together to form a cylindrical shape, the first semi-protrusion 13 and the second semi-protrusion 14 abut together to form a protrusion. The interior of the protrusion is a cavity, which is just enough to accommodate... Figure 1 The first lug 1 of the conduit protective sleeve is shown. A first half-protrusion 13 has a first half-notch 15, and a second half-protrusion 14 has a second half-notch 16. When the two sides of the first first edge 4 and the second edge 5 abut together to form a cylindrical shape, the first half-notch 15 and the second half-notch 16 form a gap. This gap is used to avoid the label attached to the first lug 1. Furthermore, the gap is small, so although paint may seep onto the first lug 1 through the gap, the area affected by the paint is small, making it easier to clean, and the conduit protective sleeve can still be reused multiple times.

[0027] The side of the first edge band 4 is integrally formed with a second hanging ear 17, which can be used to hang labels, affix labels, etc.

[0028] 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.

[0029] 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.

[0030] 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.
