[0024] The utility model provides a coal mine ventilation pipeline connection assembly: including two pipe fittings 101, multiple convex rings 102, a first connection piece 103, a second connection piece 104, multiple sealing pads 105 and multiple sets of fixing components, wherein the fixing components include a connecting column 107, a limiting arc block 108, a slider 109, a holding spring 110, a pull rod 111, a guide arc block 112, a rubber pad 113 and a protective cover 114. The above-mentioned solution solves the problem that the installation and connection of existing ventilation pipe fittings require the use of more fixing bolts, which takes more time and manpower, is inconvenient for later disassembly, and has greater difficulty for personnel.

[0025] According to this specific embodiment, the first connecting member 103 and the second connecting member 104 each have two grooves 106, and two sealing gaskets 105 are arranged on the inner side walls of the first connecting member 103 and the second connecting member 104. The plurality of convex rings 102 are respectively matched with the corresponding grooves 106, and the two pipe fittings 101 are fixedly connected with the corresponding convex rings 102. When the two pipe fittings 101 are docked, the convex rings 102 on the two pipe fittings 101 can be respectively clamped in the corresponding grooves 106 for sealing, and at the same time, the sealing gaskets 105 seal the pipe walls of the two pipe fittings 101. Through double sealing, the sealing performance of the first connecting member 103 and the second connecting member 104 is greatly increased, thereby ensuring the safety of the ventilation duct.

[0026] First, the first connecting member 103 has a plurality of fixing cavities 115, each of the fixing cavities 115 is provided with the fixing assembly and is respectively connected to the second connecting member 104, the fixing cavity 115 is L-shaped, the second connecting member 104 is connected to the first connecting member 103 through the fixing assembly, and the two pipe fittings 101 are fastened between the first connecting member 103 and the second connecting member 104.

[0027] The connecting column 107 is fixedly connected to the second connecting member 104 and is located above the second connecting member 104. The connecting column 107 has a fixing hole 116. The guiding arc block 112 is fixedly connected to the connecting column 107. The pull rod 111 is movably connected to the first connecting member 103 and inserted into the fixing cavity 115. The slider 109 is fixedly connected to the pull rod 111 and is located in the fixing cavity 115. The limiting arc block 108 is fixedly connected to the slider 109 and is located on the side of the slider 109 away from the pull rod 111. The arc block 108 is adapted to the fixed cavity 115, and the two ends of the resisting spring 110 are respectively fixedly connected to the first connecting piece 103 and the slider 109, and are sleeved on the outer wall of the pull rod 111. When the two pipes 101 are docked, the convex rings 102 on the two pipes 101 are firstly clamped in the corresponding grooves 106 for sealing, and then the first connecting piece 103 is fitted and connected with the first connecting piece 103, and the multiple connecting columns 107 on the second connecting piece 104 gradually enter the fixed cavity 115 of the first connecting piece 103. In the fixed cavity 115, the guide arc block 112 on each of the connecting columns 107 squeezes the limiting arc block 108 in the fixed cavity 115, and the limiting arc block 108 pushes the slider 109 to squeeze the resisting spring 110 and the pull rod 111, and the resisting spring 110 is compressed. When the connecting column 107 completely enters the fixed cavity 115, the rebound force of the resisting spring 110 drives the limiting arc block 108 to enter the fixing hole 116 of the connecting column 107, and the connecting column 107 is fixed in the fixed cavity 115. The connecting piece 103 and the second connecting piece 104 firmly connect the two pipe fittings 101; when the pipe fitting 101 is disassembled, the pull rod 111 is pulled outward on the first connecting piece 103, and the pull rod 111 drives the limiting arc block 108 to leave the fixing hole 116 of the connecting column 107, and then the first connecting piece 103 is separated from the second connecting piece 104, and then the pipe fitting 101 is taken out therefrom. Through the above method, it is convenient to install, connect and disassemble the two ventilation pipe fittings 101 without using fixing bolts, thereby reducing the difficulty of work for personnel.

[0028] Secondly, the rubber pad 113 is fixedly connected to the limiting arc block 108 and is located on the outer wall of the limiting arc block 108. By arranging the rubber pad 113 on the limiting arc block 108, the rubber pad 113 increases the friction between the limiting arc block 108 and the connecting column 107, so that the connecting column 107 can be firmly connected in the fixing cavity 115.

[0029] At the same time, the protective cover 114 is detachably connected to the first connecting member 103 and is located outside the pull rod 111.

When the connecting post 107 completely enters the fixed cavity 115, the rebound force of the holding spring 110 drives the limiting arc block 108 to enter the connecting post 1 07, the connecting column 107 is fixed in the fixing hole 116 of the connecting column 107, the first connecting piece 103 and the second connecting piece 104 firmly connect the two pipe fittings 101, the protective cover 114 is screwed on the first connecting piece 103, and the pull rod 111 is covered; first, the protective cover 114 is removed from the first connection, and when the pipe fitting 101 is removed, the pull rod 111 is pulled outward on the first connecting piece 103, and the pull rod 111 drives the limiting arc block 108 to leave the fixing hole 116 of the connecting column 107, and then the first connecting piece 103 is separated from the second connecting piece 104, and then the pipe fitting 101 is taken out therefrom. Through the above method, it is convenient to install, connect and disassemble the two ventilation pipe fittings 101 without using fixing bolts, which reduces the difficulty of work for personnel.

[0035] The two support rods 201 are fixedly connected to the second connecting member 104 and are symmetrically arranged below the second connecting member 104. Each of the brackets 202 is fixedly connected to the corresponding support rod 201 and is respectively located at one end of the support rod 201 away from the second connecting member 104. When the two pipe fittings 101 are connected, the two pipe fittings 101 are placed on the second connecting member 104 first.
