Description

Technical Field

[0001] The utility model relates to the technical field of metal air ducts, in particular to a corrugated butt-jointed metal air duct. Background Art

[0002] The air duct is a piping system used for air transportation and distribution. There are two types of air ducts: composite air ducts and inorganic air ducts. The composite air duct is the representative. It can be classified according to the cross-sectional shape and material. The production of stainless steel air ducts is to apply sealant (such as neutral glass glue) on the bite seams, rivet seams, flange corners and other gaps. Before applying the sealant, the surface dust and oil should be removed. According to the cross-sectional shape, the air duct can be divided into circular air ducts, rectangular air ducts, oblate air ducts and other types. Among them, the circular air duct has the smallest resistance but the largest height dimension, and the production is complicated, so the rectangular air duct is mainly used. According to the material, the air duct can be divided into metal air ducts, composite air ducts, and polymer air ducts.

[0003] However, in the prior art, when traditional air ducts are connected, pipe connection parts are required to connect the air ducts together. However, during emergency repairs, not only do you need to carry the pipe connection parts, but you also need to install the pipe connection parts, which takes a lot of time and delays the efficiency of emergency repairs. In addition, after the pipes are connected, the traditional connection equipment does not have an anti-accidental touch mechanism. Therefore, during use, if the staff accidentally touches the connection equipment, it may cause the connection device to loosen, thereby causing the pipe connection to separate.

[0040] One end of the top spring 42 away from the connecting rod 43 is fixedly connected to the cross plate 41, the outer wall of the slip ring 45 is slidably connected to the inner wall of the swivel 31, the outer wall of the connecting rod 43 is in contact with the outer wall of the fixed block 37, and the connecting rod 43 is pressed against the fixed block 37, thereby limiting the sliding position of the plug post 44, the bottom of the cross plate 41 is fixedly connected to the top of the fixed block 37, the inner wall of the fixed block 37 is slidably connected to the outer wall of the plug post 44, and the outer wall of the plug post 44 is slidably connected to the inner wall of the swivel 31.

[0041] Working principle:

[0042] When in use, first align the main pipe 1 with the auxiliary pipe 2, then align the main pipe body 5 on the main pipe 1 with the auxiliary pipe body 6 on the auxiliary pipe 2, then align the limit block 7 on the main pipe body 5 with the groove on the auxiliary pipe body 6, and then slide the limit block 7 into the groove, then rotate the main pipe body 5 to make the limit block 7 slide into the docking mechanism 3, and then rotate the docking mechanism 3 so that the docking mechanism 3 locks the limit block 7, thereby fixing the position of the main pipe body 5 and the auxiliary pipe body 6, and then start the locking mechanism 4 so that the locking mechanism 4 locks the docking mechanism 3, so that the docking mechanism 3 continues to fix the position of the main body 5.

[0043] When docking the main pipe body 5 and the auxiliary pipe body 6, it is necessary to first align the limit block 7 with the groove at the limit column 34, then slide the limit block 7 into the groove, and then rotate the main pipe body 5 so that the circular groove in the limit block 7 slides into the limit column 34. At this time, the positions of the main pipe body 5 and the auxiliary pipe body 6 are initially fixed, and then the swivel 31 is rotated. Since the top ring 33 is fixed to the swivel 31 by the connecting block 32, the top ring 33 can rotate synchronously while the swivel 31 rotates. During the rotation of the top ring 33, the top block on the top ring 33 lifts the sliding block 35, so that the sliding block 35 slides from the groove in the top ring 33 to the limit block 7. Under the continuous rotation of the top ring 33, the sliding block 35 slides next to the limit block 7, so that the limit block 7 cannot slide out of the limit column 34, thereby limiting the limit block 7. At this time, the rotation of the swivel 31 is stopped. During the sliding process of the sliding block 35, the tension spring 36 connected to the sliding block 35 is stretched to accumulate elastic potential energy.

[0044] When it is necessary to release the restriction on the limit block 7, it is only necessary to rotate the rotating ring 31 in the opposite direction so that the top ring 33 rotates in the opposite direction synchronously, and the top block can release the pushing action on the sliding block 35. Because the tension spring 36 is fixed to the auxiliary tube body 6 through the fixing block 37, the tension spring 36 cannot move on the side close to the fixing block 37. Therefore, under the pulling of the tension spring 36, the sliding block 35 can be pulled to slide in the direction of the fixing block 37, so that the sliding block 35 slides into the groove in the top ring 33, and then the main tube body 5 is rotated in the opposite direction to make the limit block 7 slide out from the limit column 34, and the main tube body 5 can be slid out from the auxiliary tube body 6.

[0045] After the locking mechanism 4 locks the docking mechanism 3, it is necessary to release the locking mechanism 4, and it is only necessary to push the slip ring 45 so that the slip ring 45 drives the plug post 44 to slide synchronously through the connecting rod 43, so that the plug post 44 slides out of the groove in the swivel 31, and the fixation of the plug post 44 to the swivel 31 can be released. Then the swivel 31 can be rotated. In the process of pushing the slip ring 45, the top spring 42 fixed on the connecting rod 43 is compressed synchronously, so that the top spring 42 accumulates elastic potential energy. When the docking mechanism 3 needs to be locked again, it is only necessary to release the thrust applied to the slip ring 45. After the thrust applied to the slip ring 45 disappears, the end of the top spring 42 fixed to the cross plate 41 is fixed and cannot move. Therefore, the top spring 42 can only release the elastic potential energy to the connecting rod 43, so as to push the plug post 44 to move in the direction of the swivel 31, so that the plug post 44 is reinserted into the swivel 31, and then the swivel 31 is re-fixed.
