Description

Technical Field

[0001] The utility model relates to the technical field of fire-resistant air ducts, in particular to an assembly connection structure of fire-resistant air ducts. Background Art

[0002] Air ducts are ventilation duct products manufactured through machining technology. They have certain green, environmentally friendly, sound-proof and heat-insulating effects. Therefore, they are widely used in stairwells, antechambers, refuge floors, etc. In the event of a fire, air ducts can prevent thick smoke from being exhausted and prevent people from suffocating, etc. Therefore, they have high requirements for fire resistance. At present, air ducts with fire-resistant board structures are usually used in the market to improve fire resistance.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the existing air ducts are fixed by bolts and nuts during connection. During the fixing process, the workers need to align the fixing holes of the air ducts before installing the bolts and nuts. However, the installation site of the air ducts is relatively high, which makes it difficult for the workers to install them. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a fire-resistant air duct assembly connection structure.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a fire-resistant air duct assembly connection structure, including an air duct main body, both ends of the air duct main body are fixedly provided with fixing plates, a fireproof layer is installed on the outer wall of the air duct main body, one of the fixing plates has a plurality of sliding grooves penetrated through the side wall, and another fixing plate has a plurality of sliding rods fixedly provided on the side wall, the plurality of sliding rods are slidably connected to the sliding grooves, and a fixing component for fixing the air duct main body is provided on the fixing plate.

[0006] By adopting the above technical solution, when the staff needs to connect the two air duct bodies to each other, the staff needs to make the slide bar face the slide groove. Then, the staff pushes the air duct body, so that the slide bar slides into the slide groove. At this time, the fixing component fixes the two air duct bodies to each other. During this process, the staff only needs to push the air duct body to complete the fixation, thereby reducing the difficulty of the staff fixing the two air duct bodies, thereby reducing the difficulty of the staff's work.

[0007] Furthermore, a blocking groove is provided on the inner wall of the slide groove, and a fixing groove opposite to the blocking groove is provided on the side wall of the slide rod. The fixing assembly includes a fixing block slidably arranged in the fixing groove and a first spring fixedly arranged on the side wall of the fixing block. The other end of the first spring is fixedly arranged on the inner wall of the fixing groove, and the fixing block is slidably connected to the blocking groove.

[0008] By adopting the above technical solution, when the slide bar slides into the slide slot, the two fixed plates gradually approach and finally abut. At this time, the fixed slot is directly opposite to the blocking slot, so that the fixed block slides in the direction close to the blocking slot under the action of the first spring, so that one end of the fixed block slides into the blocking slot. In addition, when the staff needs to slide the slide bar into the slide slot, the staff needs to slide the fixed block into the fixed slot, thereby reducing the probability of the fixed block causing obstruction.

[0009] Furthermore, a rotation groove is provided on the side wall of the slide rod, a rotation rod is rotatably arranged in the rotation groove, a fixing rope is fixedly arranged on the side wall of the rotation rod, and the other end of the fixing rope is fixed to the fixing block.

[0010] By adopting the above technical solution, when the staff needs to disassemble the air duct main body, the staff needs to rotate the rod, so that one end of the fixing rope is wrapped around the side wall of the fixing rod under the action of the rotating rod, so that the other end of the fixing rope moves away from the blocking groove, and then the fixing block slides away from the blocking groove under the action of the fixing rope, so that the fixing block and the blocking groove are separated from each other, thereby reducing the difficulty of disassembling the air duct main body for the staff, thereby reducing the difficulty of the staff's work.

[0011] Furthermore, a limit hole is provided on the inner wall of the rotating groove, and a plurality of limit grooves are arranged in an array on the inner wall of the limit hole, a limit rod is slidably provided in the limit hole, the limit rod and the rotating rod are fixed to each other, and a plurality of limit blocks are slidably provided in the plurality of limit grooves, and a plurality of the limit blocks are fixed to the limit rod.

[0012] By adopting the above technical solution, when the staff does not need to rotate the rotating rod, the staff needs to slide the rotating rod toward the direction close to the limiting hole, so that the limiting rod and the limiting block slide toward the direction close to the limiting hole under the action of the rotating rod, so that the limiting rod and the limiting block slide into the limiting hole and the limiting groove respectively, thereby reducing the probability of the rotating rod rotating when subjected to external force, thereby improving the stability of the device.

[0013] Furthermore, an annular groove is provided on the inner wall of the rotating groove, an annular block is rotatably arranged in the annular groove, and the annular block is fixed to the rotating rod.

[0014] By adopting the above technical solution, when the staff rotates or slides the rotating rod, the annular block rotates or slides along with the rotating rod under the action of the rotating rod. During this process, when the side wall of the annular block abuts against the inner wall of the annular groove, the staff cannot continue to slide the rotating rod, thereby reducing the probability of the rotating rod and the rotating groove separating from each other, thereby improving the stability of the device.

[0015] Furthermore, a receiving groove is provided on the inner wall of the rotating groove, and one end of the fixing rope away from the rotating rod passes through the receiving groove and is fixed to the fixing block.

[0016] By adopting the above technical solution, the accommodating groove reduces the probability of the fixing rope getting tangled, thereby improving the stability of the device.

[0017] Furthermore, a knob is fixedly provided on the side wall of the rotating rod.

[0018] By adopting the above technical solution, the knob reduces the difficulty for the staff to rotate the rotating rod, thereby reducing the work difficulty of the staff.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. In this application, when the staff needs to connect the two air duct bodies to each other, the staff needs to make the slide bar face the slide slot. Then, the staff pushes the air duct body, so that the slide bar slides into the slide slot. At this time, the fixing component fixes the two air duct bodies to each other. During this process, the staff only needs to push the air duct body to complete the fixation, thereby reducing the difficulty of the staff fixing the two air duct bodies, thereby reducing the difficulty of the staff's work;

[0021] 2. In the present application, when the slide bar slides into the slide slot, the two fixed plates gradually approach and finally abut. At this time, the fixed slot is directly opposite to the blocking slot, so that the fixed block slides toward the blocking slot under the action of the first spring, so that one end of the fixed block slides into the blocking slot. In addition, when the staff needs to slide the slide bar into the slide slot, the staff needs to slide the fixed block into the fixed slot, thereby reducing the probability of the fixed block causing obstruction;

[0022] 3. In the present application, when the staff needs to disassemble the air duct main body, the staff needs to rotate the rod, so that one end of the fixing rope is wrapped around the side wall of the fixing rod under the action of the rotating rod, so that the other end of the fixing rope moves away from the blocking groove, and then the fixing block slides away from the blocking groove under the action of the fixing rope, so that the fixing block and the blocking groove are separated from each other, thereby reducing the difficulty of the staff to disassemble the air duct main body, thereby reducing the difficulty of the staff's work.

[0030] When the staff needs to connect the two air duct bodies 1 to each other, the staff needs to make the slide bar 13 face the slide groove 2. Then, the staff pushes the air duct body 1, so that the slide bar 13 slides into the slide groove 2. At this time, the fixing component 3 fixes the two air duct bodies 1 to each other. In this process, the staff only needs to push the air duct body 1 to complete the fixation, thereby reducing the difficulty of the staff to fix the two air duct bodies 1, thereby reducing the difficulty of the staff to work.

[0031] A blocking groove 21 is provided on the inner wall of the slide groove 2, and a fixing groove 22 facing the blocking groove 21 is provided on the side wall of the slide rod 13.

One end of the first spring 32 is fixedly arranged on the side wall of the fixing block 31, and the other end of the first spring 32 is fixedly arranged on the inner wall of the fixing groove 22.

[0032] When the slide bar 13 slides into the slide slot 2, the two fixed plates 11 gradually approach and finally abut. At this time, the fixed slot 22 is directly opposite to the blocking slot 21, so that the fixed block 31 slides toward the blocking slot 21 under the action of the first spring 32, so that one end of the fixed block 31 slides into the blocking slot 21. In addition, when the staff needs to slide the slide bar 13 into the slide slot 2, the staff needs to slide the fixed block 31 into the fixed slot 22, thereby reducing the probability of the fixed block 31 causing obstruction.

The limiting block 51 is a rectangular block-shaped structure, and a plurality of limiting blocks 51 are provided and are slidably disposed in the plurality of limiting grooves 25, respectively, and the plurality of limiting blocks 51 are fixed to each other with the limiting rod 5.

[0036] When the staff does not need to rotate the rotating rod 4, the staff needs to slide the rotating rod 4 toward the direction close to the limiting hole 24, so that the limiting rod 5 and the limiting block 51 slide toward the direction close to the limiting hole 24 under the action of the rotating rod 4, so that the limiting rod 5 and the limiting block 51 slide into the limiting hole 24 and the limiting groove 25 respectively, thereby reducing the probability of the rotating rod 4 rotating when subjected to external force, thereby improving the stability of the device.

[0038] When the staff rotates or slides the rotating rod 4, the annular block 6 rotates or slides along with the rotating rod 4 under the action of the rotating rod 4. During this process, when the side wall of the annular block 6 abuts against the inner wall of the annular groove 26, the staff cannot continue to slide the rotating rod 4, thereby reducing the probability of the rotating rod 4 and the rotating groove 23 separating from each other, thereby improving the stability of the device.

[0039] In order to improve the stability of the device, a receiving groove 7 is provided on the inner wall of the rotating groove 23, and one end of the fixing rope 41 away from the rotating rod 4 passes through the receiving groove 7 and is fixed to the fixing block 31.

Then, the staff needs to slide the fixed block 31 into the fixed groove 22. Further, the staff pushes the air duct body 1, so that the slide bar 13 slides into the slide groove 2, and the two fixed plates 11 gradually approach and finally abut. At this time, the fixed groove 22 faces the blocking groove 21, so that the fixed block 31 slides in the direction close to the blocking groove 21 under the action of the first spring 32, so that one end of the fixed block 31 slides into the blocking groove 21, and the two air duct bodies 1 are connected to each other.
