[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] This utility model provides an industrial air conditioning duct circulation device, mainly solving the problem that the connection method between the fan 3 and the duct 1 in existing industrial air conditioning duct circulation devices makes it inconvenient to replace or maintain the fan 3. Its core innovation lies in the improved connection structure between the fan 3 and the duct 1.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] An industrial air conditioning duct circulation device, such as Figure 1 - Figure 5 As shown, the device mainly consists of a duct 1, an air outlet pipe 2, and a fan 3. The duct 1 is used for air transport and circulation, the fan 3 is the power source for driving air circulation, and the air outlet pipe 2 serves to connect the fan 3 and the duct 1. The outer wall of the fan 3 is threaded, and the outer wall of the duct 1 has a corresponding installation port 4. The fan 3 is installed on the outer wall of the duct 1 by means of threaded connection. This connection method is simple and stable, providing a basic guarantee for the normal operation of the device.

[0034] In this embodiment, the air outlet pipe 2 and the fan 3 are fixedly connected, and a positioning rod 5 is slidably installed at its end. The outer wall of the air duct 1 is provided with a positioning hole 6 corresponding to the positioning rod 5. The end of the positioning rod 5 located inside the air outlet pipe 2 is equipped with an elastic element 7, which is fixedly connected to the air outlet pipe 2. When the fan 3 is installed in place, the positioning rod 5 is inserted into the positioning hole 6 under the action of the elastic element 7, thereby further fixing the air outlet pipe 2 and the air duct 1 and preventing loosening during operation.

[0035] In some examples, the elastic element 7 is a spring whose two ends are respectively connected to the positioning rod 5 and the air outlet pipe 2.

[0036] Of course, in other examples, the elastic element 7 can also be an elastic rod with a through hole in the middle for the pull rope 8 to pass through. In this embodiment, the elastic element 7 is not directly and completely limited.

[0037] Furthermore, the end of the positioning rod 5 located in the air outlet pipe 2 in the embodiment is also provided with a pull rope 8, the air outlet pipe 2 is rotatably provided with a rope collecting wheel 9, the rope collecting wheel 9 is connected with the pull rope 8, the air outlet pipe 2 is provided with a driving component connected with the rope collecting wheel 9, the rope collecting wheel 9 is driven to rotate through the driving component, the rope collecting wheel 9 can pull the positioning rod 5 through the pull rope 8 to slide in the air outlet pipe 2, so that the restriction of the positioning rod 5 to the air outlet pipe 2 is conveniently released, the air outlet pipe 2 and the air duct 1 are separated, and the fan 3 is conveniently replaced or maintained.

[0038] In some examples, the driving component can be composed of a transmission rod 10, a pull rod 11, a storage groove 12 and a finger groove 13. In actual use, the user inserts fingers into the finger groove 13, connects the fingers with the end of the pull rod 11, pulls the pull rod 11 by the fingers to rotate 90° out of the storage groove 12. In this process, the pull rod 11 drives the rope collecting wheel 9 to rotate through the transmission rod 10, so that the rope collecting wheel 9 pulls the positioning rod 5 through the pull rope 8 to slide into the air outlet pipe 2. In this process, the positioning rod 5 extrudes the elastic member 7. When the pull rod 11 rotates 90°, the positioning rod 5 is completely pulled out of the positioning hole 6, so that the restriction of the positioning rod 5 to the air outlet pipe 2 is smoothly released.

[0039] Of course, in other examples, the driving component can also be a stepping motor. In the embodiment, the driving component is not directly and completely limited.

[0040] The working principle of the utility model is as follows: when the fan 3 needs to be replaced or maintained, first, the user starts the driving component to drive the rope collecting wheel 9 to rotate.

[0041] If the driving component is composed of the transmission rod 10, the pull rod 11, the storage groove 12 and the finger groove 13, the user inserts fingers into the finger groove 13, connects the fingers with the end of the pull rod 11, pulls the pull rod 11 by the fingers to rotate 90° out of the storage groove 12. In this process, the pull rod 11 drives the rope collecting wheel 9 to rotate through the transmission rod 10, so that the rope collecting wheel 9 pulls the positioning rod 5 through the pull rope 8 to slide into the air outlet pipe 2. In this process, the positioning rod 5 extrudes the elastic member 7. When the pull rod 11 rotates 90°, the positioning rod 5 is completely pulled out of the positioning hole 6, so that the restriction of the positioning rod 5 to the air outlet pipe 2 is smoothly released.

[0042] When the driving component is a stepping motor, the stepping motor is directly started, so that the rope collecting wheel 9 directly obtains power to start rotating.

[0043] Subsequently, the user pushes the pull rod 11, so that the air outlet pipe 2 starts to rotate, so that the fan 3 starts to move out of the mounting port 4 under the action of the screw principle, that is, the air outlet pipe 2 is disassembled.

[0044] When a new fan 3 needs to be installed or a good fan 3 needs to be maintained, the driving part is started according to the above operation, the positioning rod 5 is retracted into the air outlet pipe 2, then the end of the fan 3 is pushed into the installation opening 4, then the air outlet pipe 2 is preliminarily rotated to make the fan 3 preliminarily enter the large installation opening 4, finally the fan 3 is reversed by pulling the pull rod 11 until the outer wall of the air outlet pipe 2 is completely attached to the outer wall of the air duct 1, at this time the pull rod 11 can be pushed back into the storage groove 12, at this time the winding wheel 9 is reversed, the restriction of the pull rope 8 is released, at this time the positioning rod 5 enters the positioning hole 6 under the action of the elastic member 7, further restricts the air outlet pipe 2, ensures that the air outlet pipe 2 cannot change the angle during subsequent use, and further ensures that it cannot be loosened.
