[0035] In order to make the technical problems, technical schemes and beneficial effects to be solved by the utility model more clearly understood, the utility model will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0036] The air pipe type air conditioner is commonly known as an air pipe machine. The prior art proposes a detachable spliced air pipe machine, but the connecting mode of the spliced air pipe machine is fixed by screws, which leads to more operation time and corresponding tools when the spliced air pipe machine is assembled and disassembled, and deformation or even cracking is easily caused near the hole on the surface of the shell of the spliced air pipe machine. Based on this, the connecting structure and the spliced air pipe machine provided in the utility model can solve the problems of time and labor consumption and deformation or even cracking caused by the existing screw fixing mode.

[0037] Please see Figures 1 to 3 The utility model discloses a connecting structure for assembling and connecting the first shell 11 and the second shell 12 of the spliced air duct machine, and the connecting structure comprises:

[0038] The fixed guide rail 21 is fixedly arranged on the first shell 11.

[0039] The movable buckle 22 is provided with a clamping groove 220 clamping the splicing edge of the first shell 11 and the second shell 12 and can move along the fixed guide rail 21.

[0040] The elastic member 23 is slidably arranged on the fixed guide rail 21, and the elastic force of the elastic member 23 is released to push the movable buckle 22 to the position clamping the splicing edge of the first shell 11 and the second shell 12.

[0041] The movable buckle 22 is compressed by the elastic member 23 when the gravity of the second shell 12 is applied, and the elastic force of the elastic member 23 is released when the splicing edge of the first shell 11 contacts the splicing edge of the second shell 12.

[0042] The utility model sets the connecting structure comprising the fixed guide rail 21, the movable buckle 22 and the elastic member 23, and the movement of the movable buckle 22 is controlled by the elastic force of the elastic member 23 on one fixed guide rail 21 to realize the assembly and disassembly of the spliced air duct machine. While shortening the assembly and disassembly time of the spliced air duct machine, the number of surface openings of the shell of the spliced air duct machine is reduced. According to experimental analysis, the utility model shortens the assembly and disassembly time by 60% compared with the existing screw fixing mode, and reduces the damage to the surface of the shell of the spliced air duct machine by 50%.

[0043] In the preferred embodiment, as shown in Figure 1 The first shell 11 and the second shell 12 of the spliced air duct are assembled and connected in an up-down manner. The top edge of the first shell 11 is the splicing edge of the first shell 11, and the bottom edge of the second shell 12 is the splicing edge of the second shell 12. Of course, in other optional embodiments, the first shell 11 and the second shell 12 of the spliced air duct can be assembled and connected in a left-right manner.

[0044] As shown in Figure 3 The splicing edge of the first shell 11 is provided with an L-shaped support plate 112, and the L-shaped support plate 112 is integrally provided with a horizontal section and a vertical section. The end of the fixed guide rail 21 is connected with the vertical section of the L-shaped support plate 112. This design can stably fix the fixed guide rail 21 on the first shell 11.

[0045] In practical applications, the L-shaped support plate 112 can be integrally mounted on the joint edge of the first shell 11 by welding, and the end of the fixed guide rail 21 can be detachably mounted on the vertical section of the L-shaped support plate 112 by screw fixing.

[0046] In order to achieve the fixed connection between the end of the guide rail 21 and the vertical section of the L-shaped support plate 112 by screws, as shown in FIG. Figure 4 、 Figure 5 As shown, the end of the fixed rail 21 is provided with a plurality of pre-set holes 210, which are evenly distributed around the circumference. The number of pre-set holes 210 may be, but is not limited to, four. Meanwhile, holes are provided on the vertical section of the L-shaped support plate 112 corresponding to the pre-set holes 210 on the fixed rail 21, thereby securing the fixed rail 21 with screws.

[0047] like Figure 3 、 Figure 6 As shown, the movable clip 22 is provided with a connecting base 221 and a clamping joint 223 that together enclose a clamping slot 220. The connecting base 221 is movably mounted on the fixed guide rail 21 and extends through the first housing 11, while the clamping joint 223 extends through the horizontal section of the L-shaped support plate 112. This design limits the movable clip 22 to horizontal linear movement, ensuring that the horizontal movement of the movable clip 22 is driven solely by elastic force, thereby enabling the assembly of a spliced ​​duct unit.

[0048] like Figure 3 、 Figure 6 As shown, in order to facilitate guiding the second splicing plate of the second shell 12 to move downward to contact the splicing edge of the first shell 11 , a guiding inclined surface 2231 is provided on the top of the clamping joint 223 .

[0049] It can be understood that when splicing the first shell 11 and the second shell 12, it is only necessary to place the splicing edge of the second shell 12 on the snap joint 223 of the movable snap joint 22. At this time, because the movable snap joint 22 is subjected to the gravity of the second shell 12, the movable snap joint 22 moves toward the direction of the compression elastic part 23. At the same time, the splicing edge of the second shell 12 moves downward along the guide inclined surface 2231 on the snap joint 223. After that, the splicing edge of the second shell 12 moves to the side of the snap joint 223 and can contact the splicing edge of the first shell 11.

[0050] In practical applications, the connecting base 221 and the clamping joint 223 of the movable buckle 22 are integrally injection molded. This design can shorten assembly and disassembly time.

[0051] like Figure 4 、 Figure 5 、 Figure 6As shown, the fixed guide rail 21 is cylindrical. Such design can facilitate the movable buckle 22 to move along the fixed guide rail 21 more smoothly.

[0052] In practical application, the elastic member 23 is a metal spring, the fixed guide rail 21 is an injection molding part, and the movable buckle 22 is an injection molding part.

[0053] Please refer to Figures 1 to 6 The spliced air duct machine comprises a first shell 11 and a second shell 12, and the first shell 11 and the second shell 12 are connected by the connecting structure. The connecting structure has been described in detail in the foregoing, and will not be described again here.

[0054] Since the connecting structure is used to realize the assembly of the spliced air duct machine, the disassembly time is shortened, and the damage to the shell is also reduced.

[0055] Preferably, two connecting structures are arranged at intervals to realize the assembly connection of the first shell 11 and the second shell 12. Of course, the number of the connecting structures can be changed flexibly according to actual needs.

[0056] As shown in the figure, Figure 7 The first shell 11 is provided with a button 30, which pushes the movable buckle 22 to the position of releasing the buckling of the spliced edge of the first shell 11 and the second shell 12 when subjected to pressing force.

[0057] It can be understood that when disassembling the first shell 11 and the second shell 12, the operator only needs to press the button 30 with his hand, and the button 30 drives the movable buckle 22 to compress the elastic member 23, so as to release the clamping groove 220 of the movable buckle 22 from buckling the spliced edge of the first shell 11 and the second shell 12, facilitating the separation of the first shell 11 and the second shell 12.

[0058] In practical application, part of the shape of the button 30 can be changed, so that the operator's hand will not feel pain and discomfort when applying pressure.

[0059] For better understanding, the installation process of the connecting structure and the assembly and disassembly process of the spliced air duct machine are described in detail below.

[0060] The installation process of the connecting structure is: first, the elastic member 23 and the movable buckle 22 are sequentially sleeved on the fixed guide rail 21 to form the connecting structure, the total length of the connecting structure is shortened by pressing, the connecting structure is placed on the first shell 11 according to the corresponding position, the movable buckle 22 is first matched with the first shell 11, and then the fixed guide rail 21 is fixed with the first shell 11 by installing the screw, so as to complete the fixed installation of the connecting structure.

[0061] The assembling and disassembling process of the spliced air duct machine is as follows: when the spliced air duct machine is assembled, the device inside the machine body is assembled first, then the first shell 11 and the second shell 12 are spliced to complete the assembly. Figures 8 to 12 The first shell 11 provided with the connecting structure when not spliced is shown in the schematic view, the movable buckle 22 in the connecting structure is sleeved on the fixed guide rail 21, so that the movable buckle 22 can only realize horizontal linear motion, and the fixed guide rail 21 is provided with an elastic member 23 at one end of the movable buckle 22, when spliced, the movable buckle 22 should ensure that the elastic member 23 is pressed, the elastic member 23 exerts an opposite thrust on the movable buckle 22, so that the clamping groove 220 of the movable buckle 22 is tightly fitted on the surfaces of the two splicing edges of the two shells.

[0062] When the first shell 11 and the second shell 12 are spliced, the second shell 12 is only naturally placed in the aligned position, the movable buckle 22 in the connecting structure is pressed by the gravity of the first shell 11, so that the movable buckle 22 compresses the elastic member 23 and moves backward. Figure 10 As shown in the figure, the movable buckle 22 moves backward until the splicing edge of the second shell 12 contacts the splicing edge of the first shell 11. Finally, because the two splicing edges of the two shells contact each other, and the first shell 11 does not exert force on the movable buckle 22, the movable buckle 22 moves forward under the elastic force of the elastic member 23 to tightly fit the clamping groove 220 on the surfaces of the two splicing edges, so as to clamp the two splicing edges of the two shells in the clamping groove 220, thereby realizing the assembly of the spliced air duct machine, as shown in the figure. Figure 3

[0063] When the first shell 11 and the second shell 12 are disassembled, the operator presses the button 30 on the surface of the first shell 11, and the force exerted by the operator on the movable buckle 22 is transmitted to the elastic member 23 through the movable buckle 22, so as to compress the length of the elastic member 23, and at the same time, the movable buckle 22 moves backward. Until the movable buckle 22 moves to the limit position, the clamping groove 220 of the movable buckle 22 releases the fixing effect on the two splicing edges of the two shells, so that the second shell 12 can move freely relative to the first shell 11, thereby completing the disassembly work.

[0064] The above is only a preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.​
