Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field, and in particular relates to a ventilation hose connection device for aircraft ground air conditioning equipment. Background Technology
[0002] The ventilation system of an aircraft ground air conditioning system refers to a complete set of devices that deliver treated fresh air to the parked aircraft through ground equipment to regulate cabin temperature and humidity, ensure the cooling of electronic equipment, and ensure the comfort of passengers / crew.
[0003] Traditional ventilation hose connection devices typically use multiple screws to secure the hose to the aircraft. This method is inefficient during the connection process. Furthermore, when installing the screws, the holes need to be aligned, and another worker needs to hold and support the hose. This not only makes the operation complicated and involves many steps, but also leads to low work efficiency. Moreover, it is very inconvenient to disassemble the hose. Utility Model Content
[0004] The purpose of this utility model is to provide a connecting device for ventilation hoses of aircraft ground air conditioning equipment. When the pull ring is pulled down, the U-shaped push block moves down and inserts into the fixed plug. At this time, the pull ring slides on the limit rod and stretches the spring. The U-shaped push block pushes the locking block on the fixed plug into the limit groove. When the connection ring is contacted, the connection ring and the ventilation hose will directly detach from the connecting pipe by their own weight, which can quickly complete the disassembly. This solves the problem that traditional ventilation hose connecting devices usually use multiple screws to lock and fix the hose when connecting it to the aircraft. This method is inefficient during the connection process and requires the hole to be aligned. At the same time, another person is required to hold and support the hose, which makes the operation complicated and inefficient.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a ventilation hose connection device for aircraft ground air conditioning equipment, including a ventilation hose, an aircraft ventilation connector at the top of the ventilation hose, a connecting pipe fixedly connected to the bottom of the aircraft ventilation connector, and further comprising:
[0007] A docking mechanism is installed on top of the ventilation hose and is used to quickly connect the ventilation hose and the connecting pipe.
[0008] A disconnection mechanism is installed on the outside of the connecting pipe, and the disconnection mechanism is used to quickly disconnect the ventilation hose from the connecting pipe;
[0009] The ventilation hose has one end for connecting to a ground air conditioner, the aircraft ventilation connector is connected to the aircraft, and a sealing ring is fitted at the joint between the ventilation hose and the connecting pipe.
[0010] Furthermore, a convex ring is fixedly connected to the outside of the connecting tube. The convex ring has three square slots and three insertion holes inside. The three square slots and three insertion holes are arranged in a circular array with the connecting tube as the center. The convex ring and the connecting tube are integrally formed.
[0011] Furthermore, the docking mechanism includes a docking ring fixedly connected to the outside of the ventilation duct, and three positioning blocks fixedly connected to the top of the docking ring, the positioning blocks being arranged in a circumferential array on the docking ring; and:
[0012] The snap-fit assembly has three sets arranged in a circumferential array on the mating ring, and the snap-fit assembly is used to snap and fix with the convex ring;
[0013] The positioning plug is positioned and inserted into the socket. After the positioning plug is inserted into the socket, it positions the snap-fit component with the square slot. After the positioning plug is inserted into the protruding ring, it is used to position the fixing plug so that the fixing plug is accurately inserted into the square slot.
[0014] Furthermore, the snap-fit assembly includes a fixed insert block fixedly connected to the top of the mating ring. The fixed insert block has two limiting grooves inside. A snap-fit block is slidably connected inside the limiting grooves. A spring is fixedly connected to the inner side of the snap-fit block. The side of the spring away from the snap-fit block is fixedly connected to the inner wall of the limiting groove. Since the top of the snap-fit block is set with an incline, when the snap-fit block contacts the convex ring, it will push the snap-fit block into the limiting groove.
[0015] The top of the outer side of the card block is sloped, the bottom of the card block is flat, and the fixing block is positioned and inserted into the square slot.
[0016] Furthermore, the disengagement mechanism includes a pull ring slidably connected to the outside of the connecting tube, and three U-shaped push blocks are fixedly connected to the bottom of the pull ring. The U-shaped push blocks correspond to the square slots, and the U-shaped push blocks are U-shaped.
[0017] When the fixed plug is inserted into the square slot on the convex ring, its outer side will be inserted into the inner side of the U-shaped push block.
[0018] Furthermore, three limiting rods are slidably connected inside the pull ring, and spring two is sleeved on the outside of the limiting rods. Spring two is fixedly connected to the top of the pull ring. The limiting rods are used to limit the pull ring so that the U-shaped push block can be smoothly inserted into the square plug.
[0019] The top of the second spring is fixedly connected to the bottom of the aircraft ventilation connector, and the pull ring will stretch the second spring when it is pulled.
[0020] Furthermore, the top of the limiting rod is fixedly connected to the bottom of the aircraft ventilation connector, the bottom of the limiting rod is fixedly connected to the top of the convex ring, and the pull ring is slidably limited in conjunction with the limiting rod.
[0021] This utility model has the following beneficial effects:
[0022] 1. This utility model sets up a docking mechanism, specifically connecting the ventilation hose to the connecting pipe through a docking ring. The positioning block first inserts into the socket for positioning, and then the fixing block inserts into the square slot. When the locking block moves to the top of the convex ring, it pops out and locks the docking ring onto the convex ring. This method can quickly complete the installation by simply plugging in the connection, without the need for screws or multiple people to cooperate in the installation.
[0023] 2. This utility model features a disengagement mechanism. Specifically, when the pull ring is pulled down, the U-shaped push block moves downward and engages with the fixed insert. The U-shaped push block then pushes the locking block on the fixed insert into the limiting groove, thus contacting the restriction of the docking ring. The docking ring and the ventilation hose will then disengage directly from the connecting pipe by their own weight, allowing for quick disassembly. This method is simple to operate and more efficient.
[0024] 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 scope of protection of the present utility model.
[0034] Please see Figures 1-5 As shown, this utility model is a ventilation hose connection device for aircraft ground air conditioning equipment, including a ventilation hose 1, an aircraft ventilation connector 11 is provided at the top of the ventilation hose 1, and a connecting pipe 12 is fixedly connected to the bottom of the aircraft ventilation connector 11, and also includes:
[0035] The docking mechanism 2 is installed on the top of the ventilation hose 1 and is used to quickly connect the ventilation hose 1 and the connecting pipe 12.
[0036] Disconnection mechanism 3 is installed on the outside of connecting pipe 12 and is used to quickly disconnect ventilation hose 1 and connecting pipe 12.
[0037] The ventilation hose 1 has one end at the bottom for connecting to the ground air conditioner, the aircraft ventilation connector 11 is connected to the aircraft, and a sealing ring is fitted at the joint between the ventilation hose 1 and the connecting pipe 12.
[0038] A protruding ring 121 is fixedly connected to the outside of the connecting tube 12. The protruding ring 121 has three square slots 122 and three insertion holes 123 inside. The three square slots 122 and three insertion holes 123 are arranged in a circular array with the connecting tube 12 as the center.
[0039] The docking mechanism 2 includes a docking ring 21 fixedly connected to the outside of the ventilation hose 1. Three positioning blocks 22 are fixedly connected to the top of the docking ring 21, and the positioning blocks 22 are arranged in a circumferential array on the docking ring 21.
[0040] The snap-fit assembly 23 has three sets and is arranged in a circumferential array on the docking ring 21. The snap-fit assembly 23 is used to snap and fix with the convex ring 121.
[0041] The positioning plug 22 is positioned and inserted into the socket 123. After the positioning plug 22 is inserted into the socket 123, it positions the snap-fit component 23 with the square slot 122.
[0042] The snap-fit assembly 23 includes a fixed plug 231 fixedly connected to the top of the docking ring 21. The fixed plug 231 has two limiting grooves 232 inside. A snap-fit block 233 is slidably connected inside the limiting groove 232. A spring 234 is fixedly connected to the inside of the snap-fit block 233. The side of the spring 234 away from the snap-fit block 233 is fixedly connected to the inner wall of the limiting groove 232. When the ventilation hose 1 is docked with the connecting pipe 12 through the docking ring 21, the positioning plug 22 will first be inserted into the socket 123 for positioning. Then the fixed plug 231 will be inserted into the square slot 122. When the snap-fit block 233 moves to the top of the convex ring 121, it pops out and snaps the docking ring 21 onto the convex ring 121. This method can be quickly completed by simply using a plug-in method. It does not require the use of screws for fixing and does not require multiple people to cooperate in the installation.
[0043] The top of the outer side of the card block 233 is sloped, and the bottom of the card block 233 is flat. The fixed plug 231 is positioned and plugged into the square slot 122.
[0044] The disengagement mechanism 3 includes a pull ring 31 that is slidably connected to the outside of the connecting pipe 12. Three U-shaped push blocks 32 are fixedly connected to the bottom of the pull ring 31. The U-shaped push blocks 32 correspond to the square slots 122 and are U-shaped. When the pull ring 31 is pulled down, the U-shaped push blocks 32 move down and insert into the fixed plug 231. The U-shaped push blocks 32 then push the locking block 233 on the fixed plug 231 into the limiting groove 232. At this time, the limiting of the docking ring 21 is contacted, and the docking ring 21 and the ventilation hose 1 will directly detach from the connecting pipe 12 by their own gravity, which can quickly complete the disassembly. This method is simple to operate and more efficient.
[0045] When the fixed insert 231 is inserted into the square slot 122 on the protruding ring 121, its outer side will be inserted into the inner side of the U-shaped push block 32.

[0048] The top of the limiting rod 33 is fixedly connected to the bottom of the aircraft ventilation connector 11, the bottom of the limiting rod 33 is fixedly connected to the top of the convex ring 121, and the pull ring 31 is slidably limited to the limiting rod 33.
[0049] One specific application of this embodiment is:
[0050] In use, the ventilation hose 1 is connected to the connecting pipe 12 via the docking ring 21. A sealing ring is fitted between the ventilation hose 1 and the connecting pipe 12. When the docking ring 21 is connected to the connecting pipe 12, the positioning block 22 will first be inserted into the insertion hole 123 on the convex ring 121 to position it. Then, the fixing block 231 will be inserted into the square slot 122 on the convex ring 121. The locking block 233 will be pushed into the limiting groove 232 by the convex ring 121. At the same time, the spring 234 will be squeezed. When the locking block 233 moves to the top of the convex ring 121, the spring 234 will pop the locking block 233 out through the elastic force. At this time, the ventilation hose 1 and the connecting pipe 12 squeeze the sealing ring to achieve the sealing effect. The locking block 233 will lock the docking ring 21 onto the convex ring 121, and the docking work can be completed quickly. Then, the other end of the ventilation hose 1 can be connected to the ground air conditioner for ventilation.
[0051] When ventilation is complete and the ventilation hose 1 needs to be disassembled, the worker pulls the pull ring 31 downwards, and the U-shaped push block 32 moves downwards and engages with the fixed plug 231. At this time, the pull ring 31 slides on the limit rod 33 and stretches the second spring 34. The U-shaped push block 32 pushes the locking block 233 on the fixed plug 231 into the limit groove 232. At this time, the restriction of the docking ring 21 is contacted, and the docking ring 21 and the ventilation hose 1 will directly detach from the connecting pipe 12 by their own weight, and the disassembly can be completed quickly. After disassembly, the pull ring 31 is slowly released, and the second spring 34 will return the pull ring 31 to the top through elasticity, which is convenient for the next disassembly. At the same time, the limit rod 33 limits the pull ring 31, so that the U-shaped push block 32 can be accurately engaged with the fixed plug 231.
