Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of open protective sleeves, and in particular relates to an open protective sleeve for aerospace applications. Background Technology
[0002] Aviation refers to human flight activities within the Earth's atmosphere, encompassing numerous fields such as civil aviation and military aviation. Spaceflight refers to human activities in exploring, developing, and utilizing outer space and celestial bodies beyond Earth, involving many aspects such as spacecraft launches, space exploration, and space science experiments.
[0003] Aerospace-grade opening protective sleeves are primarily designed based on the principles of protection and sealing. From a protection perspective, they must prevent internal components such as cables from being mechanically damaged at the opening, such as by scratches, pressure, and collisions. This is because vibrations, impacts, and relative movements between equipment components occur during the operation of aerospace equipment. From a sealing perspective, they need to prevent harmful substances such as dust, liquids, and gases from entering the equipment, while also preventing leakage of internal media and ensuring the stability and safety of the internal environment of the equipment.
[0004] Currently, existing aerospace vehicles typically require the use of various cables of different specifications. Traditional protective sleeves are usually designed and manufactured according to specific cable sizes, which results in poor versatility. When faced with cables of different thicknesses, they may not fit the cables tightly, thus failing to provide good protection.
[0005] To address the aforementioned issues, this application proposes an open protective sleeve for aerospace applications. Utility Model Content
[0006] The purpose of this invention is to provide an aerospace-grade open protective sleeve that solves the problems mentioned in the background art.
[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0008] This utility model is an aerospace-grade open protective sleeve, comprising a protective sleeve, two limiting rings threadedly connected to the outer surface of the protective sleeve, two protective rings fixedly connected to the inner wall of the protective sleeve, a rubber sleeve fixedly connected to one side of the two protective rings that are close to each other and the inner wall of the protective sleeve, a valve tube and a connecting tube respectively provided on the left side of the protective sleeve, the top end of the connecting tube being fixedly connected to the bottom end of the valve tube, the right end of the connecting tube passing through one of the protective rings and being fixedly connected to the outer surface of the rubber sleeve, and a valve ball rotatably connected to the inner wall of the valve tube.
[0009] Furthermore, protective sleeves are fixedly connected to the sides of the two limiting rings that are close to each other, and each protective sleeve must be made of soft rubber.
[0010] Furthermore, each of the protective sleeves has two sets of threaded pins threadedly connected to its inner wall, and the outer surface of each set of threaded pins is threadedly connected to the inner wall of the limiting ring.
[0011] Furthermore, a protective cap is snapped onto the top of the valve tube, and an assist rod is fixedly connected to the upper surface of the protective cap.
[0012] Furthermore, a reinforcing ring is fixedly connected to the outer surface of the connecting pipe, and the right side of the reinforcing ring is fixedly connected to the left side of one of the protective rings.
[0013] Furthermore, a turning rod is provided on the outer surface of the valve tube, and one end of the turning rod near the valve tube passes through the valve tube and is fixedly connected to the outer surface of the valve ball.
[0014] Furthermore, a sealing ring is rotatably connected to the outer surface of the rotating rod, and the back of the sealing ring is fixedly connected to the outer surface of the valve tube.
[0015] This utility model has the following beneficial effects:
[0016] This utility model, by setting a protective sleeve and two limiting rings, can be fixed at the position of the aerospace opening. At the same time, by using the rotation of the valve ball in the valve tube, the valve tube can be opened or closed. Through the valve tube and the connecting tube, air can enter the rubber sleeve, causing the rubber sleeve to expand or contract within the protective sleeve and the protective ring. Thus, through the expansion and contraction of the rubber sleeve, cables of different specifications and thicknesses can be limited and protected.
[0017] In summary, by using a protective sleeve in conjunction with a limiting ring, the protective sleeve can be fixed in the opening position. The rotation of the valve ball inside the valve tube can open or close the valve tube. At the same time, by using the valve tube in conjunction with the connecting pipe, air can enter the rubber sleeve, which can then be inflated according to the thickness of the cable, thus protecting cables of different specifications.
[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5As shown, this utility model is an aerospace-grade open protective sleeve, including a protective sleeve 1. Two limiting rings 2 are threadedly connected to the outer surface of the protective sleeve 1. Two protective rings 5 are fixedly connected to the inner wall of the protective sleeve 1. A rubber sleeve 6 is fixedly connected to one side of the two protective rings 5 that are close to each other and the inner wall of the protective sleeve 1. A valve tube 8 and a connecting tube 9 are respectively provided on the left side of the protective sleeve 1. The top end of the connecting tube 9 is fixedly connected to the bottom end of the valve tube 8. The right end of the connecting tube 9 passes through one of the protective rings 5 and is fixedly connected to the outer surface of the rubber sleeve 6. A valve ball 13 is rotatably connected to the inner wall of the valve tube 8. In this embodiment, the rubber sleeve 6 is a protective device that uses the elasticity and sealing properties of rubber material to change its shape and size by inflating it with air. The rubber body has good flexibility and elasticity, and can expand after inflation and fit onto the surface of the protected object or fill the opening, playing a role in protection and sealing.
[0030] In this embodiment, the two limiting rings 2 are fixedly connected to protective sleeves 4 on their sides that are close to each other. Each protective sleeve 4 must be made of soft rubber. In this embodiment, the protective sleeves 4 can protect the limiting rings 2 and can be used to seal the connection between the limiting rings 2 and the openings in aerospace applications by utilizing their soft material.
[0031] Each protective sleeve 4 has two sets of threaded pins 3 threadedly connected to its inner wall. The outer surface of each set of threaded pins 3 is threadedly connected to the inner wall of the limiting ring 2. In this embodiment, the threaded pins 3 can move within the limiting ring 2 and the protective sleeve 4 by rotation, thereby reinforcing the connection between the limiting ring 2 and the aerospace opening.
[0032] The valve pipe 8 is fitted with a protective cover 12 at its top end. An assist rod 11 is fixedly connected to the upper surface of the protective cover 12. In this embodiment, the valve pipe 8 can be protected by the protective cover 12, and the protective cover 12 can be moved easily by the assist rod 11.
[0033] The outer surface of the connecting pipe 9 is fixedly connected to a reinforcing ring 10. The right side of the reinforcing ring 10 is fixedly connected to the left side of one of the protective rings 5. In this embodiment, the reinforcing ring 10 can reinforce the connecting pipe 9 on the protective ring 5, so that the connecting pipe 9 can be used stably.
[0034] The valve tube 8 has a screw rod 7 on its outer surface. The end of the screw rod 7 near the valve tube 8 passes through the valve tube 8 and is fixedly connected to the outer surface of the valve ball 13. In this embodiment, the screw rod 7 can be connected to the valve ball 13 and rotated to connect with the valve tube 8, so that the valve ball 13 can be easily rotated to open or close.
[0035] The outer surface of the rotating rod 7 is rotatably connected to a sealing ring 14, and the back of the sealing ring 14 is fixedly connected to the outer surface of the valve tube 8. In this embodiment, the sealing ring 14 can protect and seal the connection position between the valve tube 8 and the rotating rod 7, thereby improving the sealing performance between the devices.
[0036] Understandably, by firstly rotating the limiting ring 2 on the protective sleeve 1, the protective sleeve 1 can be fixed in the position of the aerospace opening. Then, by using the valve pipe 8 in conjunction with the valve ball 13 to open or close, air can be allowed to enter or exit the rubber sleeve 6 through the valve pipe 8 and the connecting pipe 9. At the same time, by allowing air to enter or exit, the rubber sleeve 6 can be inflated or deflated according to the thickness of the cable, thus enabling the protective sleeve 1 to protect cables of different specifications.
[0037] A specific application of this embodiment is as follows: In use, firstly, the protective sleeve 1 is placed within the aerospace opening, and the limiting ring 2 is rotatably connected to the protective sleeve 1, while simultaneously bringing the protective sleeve 4 into contact with the aerospace opening. Then, the threaded pin 3 is rotated, causing it to move within the limiting ring 2 and the protective sleeve 4, and into contact with the aerospace opening. This ensures that the protective sleeve 1 and the limiting ring 2 are stably fixed in the aerospace opening. Simultaneously, the cable is passed through the protective sleeve 1 and the rubber sleeve 6 for installation. Depending on the cable's thickness, the protective cover 12 is removed from the valve tube 8 using the assist rod 11. Simultaneously, a suitable inflation device is connected to the valve tube 8, and air is transmitted to the rubber sleeve 6 through the valve tube 8 and the connecting tube 9, causing the rubber sleeve 6 to expand within the protective sleeve 1 and the protective ring 5. When the rubber sleeve 6 expands and contacts the cable, limiting the cable, inflation into the rubber sleeve 6 is stopped. At the same time, the valve ball 13 is rotated within the valve tube 8 by turning the rod 7, causing the valve ball 13 to close the valve tube 8, thereby maintaining the air inside the rubber sleeve 6. Then, the protective cover 12 is installed on the valve tube 8 again for protection, further enabling the protective sleeve 1 to protect cables of different thicknesses at aerospace openings.
