DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1-3 The air duct structure of a wet and dry fabric setting machine shown in the figure includes an air duct pipe main body 1, and a heat preservation structure 2 is fixedly arranged at one end of the air duct pipe main body 1. The heat preservation structure 2 includes a symmetrical outer shell 201, a symmetrical inner shell 202 and a plurality of heat preservation cottons 203. The symmetrical outer shell 201 is rectangular and fixedly arranged at one end of the air duct pipe main body 1, and the inner shell 202 is respectively fixedly arranged in the inner cavity of the outer shell 201, and the middle part of the symmetrical inner shell 202 is circular, and the plurality of heat preservation cottons 203 are respectively fixedly arranged in the inner cavity of the outer shell 201 and the inner wall of the inner shell 202.

[0024] like Figure 1 and Figure 2 As shown in the figure, the outer shell 201 is composed of two concave frames, and the inner shell 202 is composed of two rectangles with semicircular end faces opposite to each other. The opening of the semicircular rings on the opposite end faces of the inner shell 202 forms a circle in the middle of the inner shell 202, so that it can adapt to the outer wall shape of the circular air duct pipe body 1. When the cross-section of the air duct pipe body 1 is rectangular, the inner shell 202 can be taken out from the inner cavity of the outer shell 201, so that the shape of the middle part of the outer shell 201 can adapt to the air duct pipe body 1 with a rectangular cross-section, and thermal insulation cotton 203 is arranged in the inner shell 202 and the outer shell 201. The thermal insulation cotton 203 is high-temperature glass wool with good thermal insulation effect, so that the outer shell 201 can be used for thermal insulation alone. Therefore, the coordinated setting of the outer shell 201 and the inner shell 202 is suitable for the thermal insulation of circular and rectangular air duct pipes, has a wide range of applications, is highly practical, can be reused, reduces the cost of thermal insulation of the air duct pipe body 1, and improves the flexibility and effectiveness of thermal insulation of the air duct pipe body 1.

[0025] The thermal insulation structure 2 further includes a plurality of merging blocks 204 and a plurality of fixed slots 205 . The plurality of merging blocks 204 are respectively fixedly disposed on the outer wall of the shell 201 . The plurality of fixed slots 205 are respectively sleeved on the outer wall of the plurality of merging blocks 204 . The fixed slots 205 are used for tightly fixing the merging blocks 204 .

[0026] like Figure 1 and Figure 2As shown in the figure, there are four merging blocks 204, and the bottom and top of a single shell 201 are provided with merging blocks 204. When the shells 201 are aligned, the merging blocks 204 fixed at the top and bottom will be tightly together. At this time, the position of the merging blocks 204 can be fixed by the sleeve of the fixed groove body 205 that is tightly attached to the merging blocks 204, so that the shells 201 can be tightly fixed. Multiple grooves are provided on both sides of the fixed groove body 205, which increases the friction for taking the fixed groove body 205, thereby providing convenience for taking the fixed groove body 205. Furthermore, the fixation between the merging blocks 204 is provided by the sleeve of the fixed groove body 205, which also provides convenience for the subsequent disassembly of the merging blocks 204, and further provides convenience for the disassembly and assembly of the shells 201.

[0027] A connection structure 3 is symmetrically arranged between the inner shell 202 and the outer shell 201, and the connection structure 3 includes a connection block 301 and a connection groove 302. The connection block 301 is fixedly arranged on one side of the inner shell 202, and the connection groove 302 is opened on the inner wall of the outer shell 201. The connection block 301 and the inner cavity of the connection groove 302 are slidably interlaced.

[0028] like Figure 2 and Figure 3 As shown in the figure, the connecting block 301 enters into the inner cavity of the connecting groove 302 from the front side of the connecting groove 302, and the inner shell 202 can be stably installed in the inner cavity of the outer shell 201 through the sliding engagement between the connecting block 301 and the inner cavity of the connecting groove 302, so that the outer shell 201 and the inner shell 202 can be used in combination, and the air duct with a circular cross-section can be used by fitting the middle shape of the inner shell 202. At the same time, the sliding engagement between the connecting block 301 and the connecting groove 302 also provides convenience for the subsequent separation of the inner shell 202 from the inner cavity of the outer shell 201, thereby effectively improving the convenience of installation and use of the inner shell 202 and the outer shell 201, and further enhancing the flexibility of disassembly and assembly between the inner shell 202 and the outer shell 201.

[0029] The connection structure 3 further includes a positioning ball 303 , a positioning groove 304 and a control component. The positioning groove 304 is provided on the back of the connection block 301 . The positioning ball 303 is embedded in the inner cavity of the positioning groove 304 . The control component is arranged on the back of the positioning ball 303 .

[0030] like Figure 3As shown in the figure, the positioning ball 303 is an elastic plastic and can undergo elastic deformation when squeezed. Therefore, when the connecting block 301 enters the inner cavity of the connecting groove 302, the connecting block 301 squeezes the positioning ball 303. The squeezed positioning ball 303 relies on the reverse support force of the external force on the positioning ball 303, so that the positioning ball 303 is squeezed toward the position of the connecting block 301, so that the positioning ball 303 can be deformed and fit into the inner cavity of the positioning groove 304, and then the connecting block 301 can use the fit between the positioning ball 303 and the positioning groove 304 to maintain a stable position in the connecting groove 302.

[0031] The control assembly includes a control rod 305 and a spring 306. The control rod 305 is fixed to the back of the positioning ball 303, and is movably interlaced with the back of the shell 201. The spring 306 is sleeved on the outer wall of the control rod 305, and the spring 306 is fixed to the inner cavity of the shell 201. The cross-section of the control rod 305 is T-shaped, and the end of the control rod 305 away from the positioning ball 303 passes through the back of the shell 201 and extends to the outside.

[0032] like Figure 3 As shown in the figure, the T-shaped setting of the control rod 305 makes it convenient for the operator to take the control rod 305. One end of the spring 306 is fixed to the outer wall of the control rod 305, and the other end of the spring 306 is fixed to the inner wall of the shell 201. The control rod 305 can be fixed on the back of the shell 201 by using the spring 306, and can also play a role in supporting the position of the positioning ball 303. When the positioning ball 303 needs to be separated from the positioning groove 304, it is only necessary to apply a pulling force away from the positioning groove 304 to the control rod 305, so that the positioning ball 303 can be separated from the positioning groove 304. Conversely, applying a pushing force to the positioning groove 304 to the control rod 305 can make the positioning ball 303 fit into the inner cavity of the positioning groove 304.

[0033] In summary, when the outer shell 201 and the inner shell 202 are used in combination, they can be adapted to air duct pipes with a circular cross-sectional shape. When encountering an air duct pipe with a rectangular cross-sectional shape, the control rod 305 is pulled to cause the control rod 305 to drive the positioning ball 303 to separate from the inner cavity of the positioning groove 304, and then the connecting block 301 is moved along the inner cavity of the connecting groove 302 toward the front of the outer shell 201. When the connecting block 301 moves, the inner shell 202 will also move synchronously, so that the inner shell 202 can be moved out of the inner cavity of the outer shell 201, and then the rectangular space of the inner cavity of the outer shell 201 will be exposed, thereby making it possible to insulate the rectangular air duct pipe with the help of the outer shell 201.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
