Technical Field

[0001] This utility model relates to the field of umbrella opener technology, specifically to a steel wire rope sealing and waterproofing device with an oil storage chamber for an umbrella opener. Background Technology

[0002] The parachute opener is a safety device widely used with parachutes. It controls the state of the parachute cords through a control mechanism, thereby opening the parachute. It is primarily used for airdrops, air-drops, and in-flight escape. Mechanical openers require external force to pull the cords apart, putting the opener in a safe position. Due to safety considerations, pulling the cords apart requires considerable force, which is inconvenient for the user, consuming physical energy and increasing preparation time for the jump.

[0003] Patent CN219406901U discloses a parachute opening force supply device for a parachute opener. After pulling the steel wire rope, the spring base moves along the guide groove inside the spring tube. As the spring base moves, the spring is continuously compressed, thus converting the spring force into the required external force to easily open the parachute. The spring tube has a guide groove to guide the spring base; a thread is provided in the middle to fix the spring tube; a positioning groove is provided on the spring tube to position the spring tube; a small step and a large step are used to support the small spring and the large spring respectively; the spring base has a bearing, and the bearing slides effortlessly when the spring base is released; the locking head on the spring tube cover and the screw cap form a step, with the small spring fitted on the small step and the large spring fitted on the large step, which serves to fix the spring.

[0004] The above solution has poor lubrication effect on the wire rope, which is prone to rust and damage after long-term use, thus causing the parachute opener to fail to open smoothly. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a steel wire rope sealing and waterproofing device with an oil storage chamber for an umbrella opener, thereby solving the problems mentioned in the background art. This utility model has a novel structure, with the steel wire rope moving left and right. Because the inner diameters of the first and third sealing rings are interference-fitted with the steel wire rope, they can block oil, ensuring that the oil in the chamber always fills the outlets on both sides, thus achieving a sealing effect.

[0006] This device solves the problem of allowing the wire rope to move left and right without leaking water into the equipment from the points where the wire rope moves.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a waterproof sealing device for a wire rope with an oil storage chamber for an umbrella opener, comprising a waterproof component. The waterproof component includes an oil storage box, a plug installed at the rear end of the oil storage box, an oil pipe fixed inside the oil storage box, a rope passing through the inside of the oil pipe, and the other end of the rope exiting from the rear end of the plug. A top cover is fixed to the front end of the rope exiting the oil storage box, and a bottom cover is fixed to the end of the rope exiting the plug. A spring assembly is fixedly installed between the rear end of the plug and the bottom cover. The spring assembly includes a large spring and a small spring, with the large spring encased inside the small spring.

[0008] Furthermore, an outer cover is fixed to the outer end of the oil storage box.

[0009] Furthermore, the rear end of the plug is fixed with a threaded post, and the top cover can be threaded onto the threaded post.

[0010] Furthermore, a first sealing ring is provided at the end of the threaded post corresponding to the end through which the rope passes.

[0011] Furthermore, a second sealing ring is provided at the connection end between the plug and the oil reservoir.

[0012] Furthermore, a third sealing ring is provided at one end of the oil pipe located inside the oil storage box.

[0013] Furthermore, a small hole is provided on the left side of the oil storage box, and a large hole is provided on the right side of the oil storage box.

[0014] Furthermore, the inner holes of the first and third sealing rings are interference-fitted with the rope body and fit tightly against it.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model uses the inner holes of the first and third sealing rings to make interference fit with the rope body, so that they fit tightly against the rope body. When the rope body moves, it prevents the oil in the cavity from leaking out with the rope body, thus playing a waterproof role. The second sealing ring is used to block the gap generated when the oil storage box and the plug are fitted together, thus playing a waterproof role.

[0017] 2. Because the inner diameters of the first and third sealing rings are interference-fitted with the rope body, the oil in this utility model can block the oil. The oil in the cavity is always full of the left and right outlets, which plays a sealing role. The rope body can move left and right, but it can also prevent water from leaking into the equipment from the moving parts of the rope body.

[0018] 3. Compared with the prior art, the present invention allows the wire rope to move left and right. Because the inner diameters of the first and third sealing rings are interference-fitted with the wire rope, the oil inside the cavity is always filled with oil at both the left and right outlets, thus achieving a sealing effect.
