Description

Technical Field

[0001] This utility model relates to the field of duct air conditioning technology, and in particular to a quick-installation structure and duct air conditioning system. Background Technology

[0002] Currently, ducted air conditioners are widely used in residential settings. The indoor unit of the ducted air conditioner is installed indoors. Due to the small installation space and aesthetic reasons, the maintenance access is generally quite small. For the traditional structure of the indoor unit of the ducted air conditioner, it is necessary to break the ceiling to replace the motor after the service. However, the disassembly and installation of the ceiling is quite difficult, making it difficult to operate during after-sales maintenance.

[0003] Existing technologies include detachable ducted air conditioners, which are mainly designed as two detachable connection structures. The two parts can be spliced ​​together to form a normal ducted air conditioner that can meet the functions of a ducted air conditioner. During installation or maintenance, the two parts can be accessed through the access ports above the ceiling to see if the ducted air conditioner meets the installation requirements of a smaller access port.

[0004] However, existing ductwork units use bolts to connect the two parts, which requires a high degree of precision in the alignment of the two parts. This often leads to misalignment during assembly, resulting in time-consuming and labor-intensive assembly and affecting assembly efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-installation structure and duct unit to solve the technical problem of low assembly efficiency in existing detachable duct units. The various technical effects of the preferred technical solutions provided by this utility model are detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0054] This utility model provides a quick-assembly structure and duct machine that improves assembly efficiency.

[0055] The following is combined with Figures 1 to 17The technical solution provided by this utility model will be described in more detail.

[0056] This utility model provides a quick-installation structure 100, comprising:

[0057] A plug-in portion 110 is provided on one of the fan section 200 and the evaporator section 300, and the plug-in portion 110 is provided with a plug-in hole 111;

[0058] A mating part 120 is provided on the other side of the fan section 200 and the evaporator section 300. The mating part 120 is provided with a mating hole 121, which is parallel to the central axis of the insertion hole 111.

[0059] A positioning member 130 is provided, and a guide structure is provided between the positioning member 130 and the insertion part 110. When the fan section 200 and the evaporator section 300 approach each other to the point that the insertion hole 111 and the mating hole 121 at least partially overlap, the positioning member 130 can pass through the mating hole 121 and the insertion hole 111 in sequence under the action of the guide structure, so that the insertion hole 111 and the mating hole 121 are coaxially connected.

[0060] The quick-installation structure 100 provided by this utility model includes a plug-in portion 110, a mating portion 120, and a positioning member 130. The plug-in portion 110 and the mating portion 120 are respectively disposed on the fan section 200 and the evaporator section 300. The plug-in portion 110 is provided with a plug-in hole 111, and the mating portion 120 is provided with a mating hole 121. A guide structure is provided between the positioning member 130 and the plug-in portion 110. When the fan section 200 and the evaporator section 300 are close to each other, the plug-in hole 111 and the mating hole 121 are at least close to each other. When partially overlapping, the positioning member 130 can pass through the mating hole 121 and the insertion hole 111 in sequence under the action of the guide structure, so that the insertion hole 111 and the mating hole 121 are coaxially connected. As long as the fan section 200 and the evaporator section 300 are close to each other, and the insertion hole 111 and the mating hole 121 are at least partially overlapped, the two can be connected by the positioning member 130. This reduces the precision requirements during assembly, thereby solving the problem of difficult-to-control docking precision in the prior art and greatly improving assembly efficiency.

[0061] Understandably, in the prior art, the duct unit is set up as a two-part structure with connection holes on both parts, and connected by bolts. During docking, it is necessary to ensure that the connection holes on the two parts coincide before they can be connected. However, in this patent application, a guide structure is provided between the positioning member 130 and the insertion part 110. The guide structure can ensure that the positioning member 130 passes through the mating hole 121 and the insertion hole 111 in sequence, thereby realizing the rapid connection of the partially overlapping fan section 200 and evaporator section 300, making the insertion hole 111 and the mating hole 121 coincide, thus greatly improving the assembly efficiency.

[0062] In some embodiments of this utility model, the guiding structure includes a tapered hole 116 provided on the side of the insertion portion 110 near the mating portion 120. The tapered hole 116 is coaxially arranged with the insertion hole 111, and the maximum diameter of the tapered hole 116 is oriented towards the mating portion 120.

[0063] In some embodiments of the present invention described above, a tapered hole 116 is provided on the side of the insertion part 110 near the mating part 120. The tapered hole 116 and the insertion hole 111 are coaxially arranged, and the maximum diameter of the tapered hole 116 is oriented towards the mating part 120. When the positioning member 130 passes through the mating hole 121, it will first contact the tapered hole 116 and gradually pass through the insertion hole 111 along the tapered hole 116. Under the guidance of the tapered hole 116, it will pass through the mating hole 121 and the insertion hole 111 in sequence, thereby realizing the rapid connection of the partially overlapping fan section 200 and evaporator section 300, making the insertion hole 111 and the mating hole 121 coincide, thereby greatly improving the assembly efficiency.

[0064] It should be noted that, since a tapered hole 116 is provided on the insertion part 110, when the positioning member 130 is a positioning bolt, after the positioning bolt passes through the mating hole 121, it can gradually drive the insertion part 110 and the mating part 120 to move relative to each other under the guidance of the tapered hole 116, thereby causing the mating hole 121 and the insertion hole 111 to move in the coaxial direction, ensuring that the evaporator section 300 and the fan section 200 can be quickly connected, thus improving assembly efficiency.

[0065] In some embodiments of the present invention, the guide structure includes a tip 131 disposed at the end of the positioning member 130.

[0066] In some embodiments of the present invention described above, the guiding structure includes a tip 131 disposed at the end of the positioning member 130. When the insertion hole 111 and the mating hole 121 at least partially overlap, the tip 131 can be inserted into the area where the two partially overlap, thereby driving the fan section 200 and the evaporator section 300 to move relative to each other. This causes the mating hole 121 and the insertion hole 111 to move in a coaxial direction, ensuring that the evaporator section 300 and the fan section 200 can be quickly connected, thus improving assembly efficiency.

[0067] It should be noted that, since a tip 131 is provided at the end of the positioning member 130, after the positioning member 130 passes through the mating hole 121, the tip 131 of the positioning member 130 can be inserted into the area where the insertion hole 111 and the mating hole 121 at least partially overlap, and then the mating hole 121 and the insertion hole 111 move in the coaxial direction to ensure that the evaporator section 300 and the fan section 200 can be quickly connected, thereby improving assembly efficiency.

[0068] In some embodiments of this utility model, the insertion part 110 is further provided with a guide part 112, and the mating part 120 is provided with a guide hole 122. The guide hole 122 and the mating hole 121 are coaxially arranged, and the guide part 112 and the guide hole 122 are mated together.

[0069] In some embodiments of the present invention described above, the insertion part 110 is provided with a guide part 112, and the mating part 120 is provided with a guide hole 122. The guide hole 122 and the guide part 112 cooperate with each other. Through the guide part 112 and the guide hole 122, the insertion part 110 and the mating part 120 can move relative to each other, so that the mating hole 121 and the insertion hole 111 can move in the coaxial direction, thereby further ensuring the rapid docking of the evaporator section 300 and the fan section 200 and improving the assembly efficiency.

[0070] In some embodiments of this utility model, the mating part 120 includes a fixing plate 123 and two connecting plates 124. The two connecting plates 124 are arranged parallel to each other at both ends of the fixing plate 123. The insertion hole 111 and the guide hole 122 are respectively arranged on the two connecting plates 124.

[0071] In some embodiments of the present invention described above, the mating part 120 includes a fixing plate 123 and two connecting plates 124. The two connecting plates 124 are arranged in parallel and are located at both ends of the fixing plate 123. The insertion hole 111 is arranged parallel to the central axis of the mating hole 121, and the guide hole 122 is coaxial with the mating hole 121. When the fan section 200 and the evaporator section 300 move closer to each other, the guide part 112 and the guide hole 122 can play a guiding role, facilitating the movement of the fan section 200 and the evaporator section 300. The fan section 200 and the evaporator section 300 move relative to each other so that the insertion hole 111 and the mating hole 121 move in a coaxial direction, ensuring that the fan section 200 and the evaporator section 300 can quickly reach a state where the insertion hole 111 and the mating hole 121 are at least partially overlapped, so that the positioning member 130 can quickly connect the fan section 200 and the evaporator section 300; at the same time, when the positioning member 130 passes through the mating hole 121 and the insertion hole 111, it can also play a good guiding role, so that the insertion hole 111 and the mating hole 121 can quickly reach a coaxial state, further improving assembly efficiency.

[0072] In some embodiments of this utility model, the insertion part 110 includes a cylindrical section 113, the guide part 112 is a tapered section 114 disposed on the first side of the cylindrical section 113, a fixing section 115 is disposed on the side of the cylindrical section 113 away from the guide part 112, and the insertion hole 111 is a through hole penetrating the tapered section 114, the cylindrical section 113 and the fixing section 115.

[0073] In some of the embodiments of the present invention described above, the insertion part 110 includes a cylindrical section 113 and a guide part 112 is a tapered section 114 disposed on the first side of the cylindrical section 113. The tapered section 114 can cooperate with the guide hole 122, so that the insertion hole 111 and the mating hole 121 can quickly become coaxial, thereby improving assembly efficiency.

[0074] Furthermore, the side of the cylindrical section 113 away from the guide portion 112 is a fixed section 115, which is used to connect with the fan section 200 and the evaporator section 300.

[0075] In some embodiments of this utility model, the insertion hole 111 is a threaded hole, the positioning member 130 is a positioning bolt, and the positioning bolt is threadedly engaged with the threaded hole.

[0076] In some of the embodiments of this utility model described above, the positioning member 130 is a positioning bolt, and the insertion hole 111 is a threaded hole. When the positioning member 130 passes through the mating hole 121, under the combined action of the tapered hole 116, the guide part 112, and the guide hole 122, the positioning member 130 can quickly become coaxial with the insertion hole 111, thereby connecting the fan section 200 and the evaporator section 300, which greatly improves the assembly efficiency.

[0077] It is understood that the positioning element 130 can also be a screw or other connecting element. The insertion hole 111 can also be a through hole, through which the positioning bolt passes and connects to the nut.

[0078] In some embodiments of this utility model, the insertion part 110 includes a first positioning plate 117, and a plurality of first bushings 118 are provided on the first positioning plate 117, and the central holes on the plurality of first bushings 118 are coaxially arranged to form the insertion hole 111.

[0079] The mating part 120 includes a second positioning plate 125, on which a plurality of second bushings 126 are provided. The center holes on the second bushings 126 are coaxially arranged to form the mating hole 121. The first bushings 118 and the second bushings 126 are arranged alternately.

[0080] In some embodiments of the present invention described above, the insertion part 110 includes a first positioning plate 117, on which a plurality of first bushings 118 are provided, and the central holes of the plurality of first bushings 118 are coaxially arranged to form an insertion hole 111; the mating part 120 includes a second positioning plate 125, on which a plurality of second bushings 126 are provided, and the central holes of the plurality of second bushings 126 are coaxially arranged to form a mating hole 121, and the first bushings 118 and the second bushings 126 are arranged alternately, and the positioning member 130 can pass through the central holes of the second bushings 126 and the central holes of the first bushings 118 in sequence, thereby connecting the insertion part 110 and the mating part 120.

[0081] It should be noted that, since the first bushing 118 and the second bushing 126 are arranged in an alternating manner, when the center holes of the first bushing 118 and the second bushing 126 at the outermost positions coincide, the positioning member 130 can drive the insertion part 110 and the mating part 120 to move relative to each other by passing through the center holes of the first bushing 118 and the second bushing 126, thereby connecting the fan section 200 and the evaporator section 300.

[0082] In some embodiments of this utility model, a tapered hole is provided on the first bushing 118, and the tapered hole is oriented toward the second bushing 126.

[0083] This utility model also provides a duct air conditioner, including the quick-installation structure 100 as described above.

[0084] The ductwork machine provided by this utility model includes the quick-installation structure 100 as described above, which also reduces the precision requirements during assembly, thereby solving the problem of difficult-to-control docking precision in the prior art and greatly improving the assembly efficiency.

[0085] In some embodiments of this utility model, a fan section 200 and an evaporator section 300 are included, and a sealing element 400 is provided between the fan section 200 and the evaporator section 300.

[0086] In some embodiments of the present invention described above, by providing a sealing element 400 between the fan section 200 and the evaporator section 300, a good sealing effect is achieved between the fan section 200 and the evaporator section 300 after they are assembled by the quick-installation structure 100 as described above.

[0087] In some embodiments of this utility model, the sealing element 400 is a buffer sponge or a sealing rubber pad.

[0092] A mating part 120 is provided on the evaporator section 300. The mating part 120 is provided with a mating hole 121, which is parallel to the central axis of the insertion hole 111.

[0093] When the fan section 200 and the evaporator section 300 approach each other to the point that the insertion hole 111 and the mating hole 121 at least partially overlap, the positioning member 130 can pass through the mating hole 121 and the insertion hole 111 in sequence under the action of the guide structure, so that the insertion hole 111 and the mating hole 121 are coaxially connected.

[0094] Furthermore, the insertion part 110 is provided with a guide part 112, and the mating part 120 is provided with a guide hole 122. The guide hole 122 and the mating hole 121 are coaxially arranged, and the guide part 112 and the guide hole 122 are mated together.

The insertion hole 111 and the guide hole 122 are respectively provided on the two connecting plates 124.

[0096] The insertion part 110 includes a cylindrical section 113, the guide part 112 is a tapered section 114 disposed on the first side of the cylindrical section 113, the insertion hole 111 is a through hole penetrating the tapered section 114 and the cylindrical section 113, and a fixing section 115 is disposed on the side of the cylindrical section 113 away from the tapered section 114.
