[0028] The present invention will be further described in detail below in conjunction with specific embodiments so that those skilled in the art can understand the present invention more clearly.

[0029] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0030] like Figure 1 As shown, this embodiment provides an auxiliary installation device for air duct insulation cotton, including a base 2, a lifting unit, an adjustment unit, and a pressing plate 15.

[0031] The lifting unit is installed on the base 2 .

[0032] like Figure 2 As shown, the adjustment unit includes a slide 10, a slider 17, and a guide rod 12. The slide 10 is installed on the lifting end of the lifting unit. A screw 13 is rotatably installed on the slide 10. A nut is screwed to the screw 13. The slider 17 is fixed to the nut. The slider 17 and the slide 10 are slidably matched. The slide 10 is horizontally arranged. The axial direction of the screw 13 is parallel to the sliding direction of the slide 10. Similar to the principle of a screw transmission mechanism, by rotating the screw 13, the nut can be driven to move axially along the screw 13, thereby driving the slider 17 to slide along the slide 10.

[0033] Two guide seats 18 are installed on the slider 17. The guide rod 12 is inserted into the two guide seats 18 at the same time. The guide seats 18 are adapted to the guide rod 12, so that the guide rod 12 can move stably along the axial direction of the guide seats 18. An adjustment rod 11 is rotatably installed on the slider 17. An adjustment gear is coaxially fixed to the adjustment rod 11. Saw teeth adapted to the adjustment gear are provided on the side wall of the guide rod 12, and the adjustment gear is meshed with the saw teeth. The saw teeth are arranged along the axial direction of the guide rod 12. By rotating the adjustment rod 11, the adjustment gear can be driven to rotate, and then the guide rod 12 can be driven to move axially.

[0034] The pressing plate 15 is of a punching type and is provided with a plurality of elastic clips 16 for fixing the heat-insulating nails. The pressing plate 15 is installed on the guide rod 12 .

[0035] Based on the above structure, by rotating the screw 13, the pressure plate 15 can be moved axially along the screw 13 on the plane, and by rotating the adjusting rod 11, the pressure plate 15 can be moved axially along the guide rod 12 on the plane, that is, the pressure plate 15 can be moved freely on the plane through the adjusting unit; the slide 10 can be driven to move freely in the vertical direction through the lifting unit, and then the pressure plate 15 can be driven to move freely in the vertical direction.

[0036] In summary, the auxiliary installation device for duct insulation cotton provided in this embodiment allows users to calculate the installation density of insulation nails and the spacing required to place insulation nails in advance according to the installation requirements of insulation nails, and set them in advance on the pressing plate 15, and fix the elastic clamp 16. During installation, according to the site conditions, the pressing plate 15 is moved to the specified position in combination with the adjustment unit and the lifting unit, and then the pressing plate is pressed (the insulation cotton installation steps are the same as above), thereby realizing the installation of duct insulation cotton. There is no need to mark the lines in advance for positioning, thereby reducing construction time and increasing work efficiency. It also avoids the problem of being unable to guarantee construction quality due to space limitations when constructing in confined spaces.

[0037] like Figure 2 As shown, in this embodiment, a rocker is coaxially fixed to the end of the adjusting rod 11, which is conducive to the staff to quickly rotate the adjusting rod 11.

[0038] A rocker is coaxially fixed to the end of the screw rod 13. Similarly, it is beneficial for the staff to quickly rotate the screw rod 13.

[0039] like Figure 1 , 3As shown, in this embodiment, the lifting unit includes a motor 7, two lifting slide rails 4, and two sliding platforms 14. The two sliding platforms 14 are respectively slidably matched with the two lifting slide rails 4. Two transmission wheels are rotatably installed on the lifting slide rails 4. The two transmission wheels are connected by a lifting chain 9. The motor 7 is used to drive the lifting chain 9 to transmit. The lifting slide rails 4 are arranged vertically, and the lifting chain 9 is transmitted vertically. The sliding platform 14 is fixedly connected to the lifting chain 9. The slide 10 is installed between the two sliding platforms 14. The lifting slide rails 4 are vertically provided with strip holes. The strip holes are used for the screw rod 13 to pass through, so as to avoid interference between the screw rod 13 and the lifting slide rails 4, and at the same time, it is beneficial for the staff to quickly rotate the screw 13 from the outside.

[0040] The lifting chain 9 is driven by the motor 7 to drive the sliding platform 14 to slide up and down along the lifting rail 4, and the sliding table 10 can be driven to move freely in the vertical direction.

[0041] The top ends of the two lifting rails 4 are connected by a fixed cover plate 5. The fixed cover plate 5 can enhance the stability of the lifting rail 4, and the motor 7 can be installed on the fixed cover plate 5.

[0042] like Figure 3 As shown, a driving wheel is coaxially fixed to the power output end of the motor 7, a rotating shaft 6 is rotatably mounted on the lifting slide rail 4, a passive wheel is coaxially fixed to the outer side of the rotating shaft 6, the driving wheel and the passive wheel are connected by a transmission chain 8, a driving wheel is coaxially fixed to the rotating shaft 6, and the driving wheel and the two transmission wheels are connected by the lifting chain 9.

[0043] The motor 7 drives the driving wheel to rotate, which in turn drives the driven wheel to rotate, which in turn drives the rotating shaft 6 to rotate, and then drives the driving wheel to rotate, thereby driving the lifting chain 9 to transmit.

[0044] Please refer again Figure 1 In this embodiment, a slide groove 3 is installed on the base 2, and the lifting slide rail 4 is slidably matched with the slide groove 3.

[0045] A plurality of screw holes are provided on the side wall of the slide groove 3 , and the plurality of screw holes are evenly spaced along the sliding direction of the slide groove 3 . A locking screw is screwed into the screw hole, and the inner end of the locking screw contacts the lifting slide rail 4 .

[0046] The lifting rail 4 can slide forward and backward in the slide groove 3. By rotating the locking screw so that the inner end of the locking screw contacts the side wall of the lifting rail 4, the lifting rail 4 can be locked, and the position of the lifting rail 4 can be freely adjusted forward and backward.

[0047] In this embodiment, four legs 1 are installed at the bottom end of the base 2 , and the four legs 1 are respectively located at the four corners of the base 2 .

[0048] The length of the supporting leg 1 can be adjusted, and the length of the supporting leg 1 can be adjusted according to actual needs before use.

[0049] The mechanisms, components and parts not specifically described in the present invention are all existing structures in the prior art and can be directly purchased from the market.
