[0036] Figure 1 FIG. 1 is a schematic partial structural diagram of a screw cap and an air conditioner using the screw cap according to an embodiment of the utility model, as shown in FIG. Figure 1 As shown, and refer to Figures 2 to 9 The embodiment of the utility model provides a screw cap, the screw cap 130 is adapted to the structural hole 120 defined on the housing 110 of the air conditioner, and the screw cap 130 includes a cover 131 and a connection seat 132. The cover 131 is made of plastic material and / or metal material, and defines a receiving cavity opened to at least one side, and is configured to be detachably connected in the structural hole 120. The connection seat 132 is arranged in the structural hole 120, and is connected to the cover 131, and forms an anti-detachment portion 133 for telescopically connecting or folding the housing 110.

[0037] In the screw cap 130 of the embodiment of the utility model, since the anti-detachment part 133 is connected to the housing 110 by telescopic connection or folding connection, when the housing needs to be opened and the screws need to be removed, when the connecting seat 132 and the cover 131 accommodating the connecting seat 132 are separated from the structural hole 120, the connecting seat 132 and the cover 131 accommodating the connecting seat 132 are still connected to the housing 110 through the anti-detachment part 133, thereby preventing the screw cap 130 from being lost. In addition, since the cover 131 is made of plastic material or metal material, it can be consistent with the material of the housing 110, so that the overall surface of the housing 110 is smooth and beautiful, dust is not easy to adhere, and it is easy to clean. In summary, the utility model not only prevents the screw cap 130 from being lost, but also increases the aesthetics of the screw cap 130, and makes the screw cap 130 easy to clean, thereby improving the user experience.

[0038] Furthermore, since the anti-detachment portion 133 can be compressed or folded to connect the housing 110, that is, when the screw nut 130 is installed in place, the anti-detachment portion 133 will not be exposed outside the housing 110, making the housing 110 neat and beautiful, meeting people's aesthetic needs and improving market competitiveness.

[0039] In an alternative embodiment of this embodiment, a portion of the cover 131 is made of plastic material and another portion is made of metal material.

[0040] In some embodiments of the utility model, the material of the cover shell 131 is the same as that of the housing 110. That is, when the housing 110 is made of a plastic material, the cover shell 131 is made of the same plastic material as that of the housing 110. When the housing 110 is made of a metal material, the cover shell 131 is made of the same metal material as that of the housing 110. When a part of the housing 110 is made of a plastic material and the other part is made of a metal material, a part of the cover shell 131 corresponding to the housing 110 is made of a plastic material, and the other part is made of a metal material. Since the material of the cover shell 131 is always consistent with that of the housing 110, when the cover shell 131 is assembled in the structural hole 120, the outer surface of the housing 110 is neat and beautiful.

[0041] During the assembly process, the connection base 132 is first installed in the accommodating cavity of the cover 131 to complete the assembly of the screw cap 130. Then, the anti-detachment portion 133 on the connection base 132 is connected to the housing 110 of the air conditioner, and then the anti-detachment portion 133 is compressed or folded toward the housing 110, so that the connection base 132 connected to the anti-detachment portion 133 and the cover 131 accommodating the connection base 132 enter the structural hole 120 of the housing 110, and the screw cap 130 is connected to the structural hole 120.

[0042] Alternatively, during the assembly process, the anti-detachment portion 133 on the connection seat 132 is first connected to the housing 110 of the air conditioner, and then the anti-detachment portion 133 is compressed or folded toward the housing 110, so that the connection seat 132 connected to the anti-detachment portion 133 enters the structural hole 120. After the connection seat 132 is installed in place, the housing cavity of the cover shell 131 is directed toward the structural hole 120 and the cover shell 131 is pressed until the connection seat 132 enters the housing cavity and the cover shell 131 enters the structural hole 120, and the assembly is completed.

[0043] In some embodiments of the present invention, the connection seat 132 and the anti-detachment portion 133 are integrally formed of elastic material, and the anti-detachment portion 133 is in an elastically stretched state at least when the connection seat 132 is detached from the structural hole 120 .

[0044] In this embodiment, during the assembly process, the anti-detachment portion 133 is first connected to the housing 110, and the anti-detachment portion 133 is in an elastically stretched state. Then, the connection seat 132 is pressed into the structural hole 120, and the anti-detachment portion 133 is compressed or folded accordingly, until the connection seat 132 is assembled in place in the structural hole 120. Since the connection seat 132 and the anti-detachment portion 133 are both made of elastic material, the surface of the elastic material is generally rough, which increases the friction between the screw cap 130 and the structural hole 120, making it difficult for the screw cap 130 to fall out of the structural hole 120.

[0045] Furthermore, since the connection seat 132 and the anti-detachment portion 133 are integrally formed of elastic material, that is, the entire connection seat 132 and the anti-detachment portion 133 can be formed by one mold, the production efficiency is greatly improved compared to a separate structure.

[0046] Furthermore, since the connection seat 132 and the anti-detachment portion 133 are integrally formed with elastic material, that is, the connection between the connection seat 132 and the anti-detachment portion 133 is very firm and not easy to be disconnected.

[0047] In some embodiments of the present invention, the elastic material is rubber. Rubber is relatively cheap, which reduces the production cost of the screw cap 130.

[0048] It can be seen from the above embodiments that the cover 131 is made of plastic material or metal material, and the cover 131 is covered on the connecting seat 132 made of rubber material, so that the connecting seat 132 is not exposed to the housing 110, making the outer surface of the housing 110 beautiful.

[0049] In some embodiments of the present invention, Figures 3 to 5 As shown, the anti-detachment portion 133 includes a rod portion 1331 extending in a straight line and a first boss 1332. One end of the rod portion 1331 is connected to the connection seat 132. The first boss 1332 is disposed on the rod portion 1331 and is close to the other end of the rod portion 1331. The first boss 1332 is exposed from the outer periphery of the rod portion 1331 to facilitate the housing 110 to stop at the side of the first boss 1332 close to the connection seat 132 when the connection seat 132 is separated from the structural hole 120.

[0050] In this embodiment, during the assembly process, the first boss 1332 on the rod 1331 is passed through the housing 110, so that the housing 110 is located between the first boss 1332 and the connecting seat 132, and the housing 110 is stopped at the side of the first boss 1332 close to the connecting seat 132. Then, the connecting seat 132 is assembled into the structural hole 120. When the connecting seat 132 is separated from the structural hole 120, since the housing 110 is stopped at the side of the first boss 1332 close to the connecting seat 132, the connecting seat 132 can still be connected to the housing 110, thereby preventing the connecting seat 132 from being lost.

[0051] It can be seen from the above embodiments that since the rod portion 1331 of the anti-detachment portion 133 extends in a straight line, the structure is very simple. Compared with the anti-detachment portion 133 with a special shape, the rod portion 1331 extending in a straight line makes installation more convenient.

[0052] In some embodiments of the present invention, Figure 4As shown, at least two opposite sides of the connection base 132 define a groove 1321. Correspondingly, a second boss 1313 protruding from the cavity wall of the accommodating cavity is formed in the cover 131, and the second boss 1313 fits in the groove 1321 to promote the connection base 132 and the cover 131 to be snap-fitted.

[0053] In this embodiment, during the assembly of the screw cap 130, the connection seat 132 is assembled into the accommodating cavity, and when the second boss 1313 in the accommodating cavity is buckled into the groove 1321 of the connection seat 132, the connection seat 132 is assembled in place in the accommodating cavity, so that the connection seat 132 is connected to the housing 131. The connection structure of the second boss 1313 and the groove 1321 is used to connect the connection seat 132 to the housing 131. The connection structure is very simple, the assembly steps are relatively few, and the assembly efficiency is guaranteed.

[0054] In some embodiments of the present invention, Figure 5 As shown, the first side surface of the cover shell 131 is in the shape of a smooth curved surface, so that when the cover shell 131 is installed in the structural hole 120, the first side surface of the cover shell 131 and the surface of the housing 110 are on the same smooth curved surface.

[0055] In this embodiment, during assembly, the first side of the cover 131 faces outward, and then the cover 131 is pressed into the structural hole 120. After the cover 131 enters the structural hole 120 and is assembled in place, the first side of the cover 131 and the surface of the housing 110 are on the same smooth curved surface, making the outer surface of the housing 110 beautiful and catering to the public's aesthetic taste.

[0056] In some embodiments of the present invention, Figure 6 As shown, the first side profile of the cover shell 131 is adapted to the outer surface profile of the structural hole 120. After the cover shell 131 is assembled in the structural hole 120, the gap between the first side of the cover shell 131 and the structural hole 120 is very small, making the outer surface of the housing 110 more beautiful.

[0057] In some embodiments of the present invention, Figures 3 to 5 As shown, at least one third boss 1311 protruding from the side is formed on the cover shell 131 , and the at least one third boss 1311 is configured to be snap-connected to the assembly hole 121 defined on the hole wall of the structural hole 120 .

[0058] In this embodiment, the cover shell 131 has a third boss 1311, and the corresponding hole wall of the structural hole 120 has an assembly hole 121 that matches the third boss 1311. During assembly, the cover shell 131 is pressed into the structural hole 120, and when the third boss 1311 of the cover shell 131 enters the assembly hole 121 on the hole wall of the structural hole 120, the cover shell 131 is assembled in place in the structural hole 120. The provision of the third boss 1311 and the assembly hole 121 makes the assembly process between the cover shell 131 and the structural hole 120 simple, and the assembly is firm and reliable after assembly.

[0059] In some embodiments of the utility model, the third boss 1311 is made of an elastic material, and the third boss 1311 can be elastically deformed. During the installation process, as the distance between the third boss 1311 and the hole wall of the structural hole 120 becomes closer and closer, when the third boss 1311 contacts the hole wall of the structural hole 120, the third boss 1311 is deformed, so that the cover 131 can continue to move into the structural hole 120. After the third boss 1311 enters the assembly hole 121, due to the loss of pressure, the third boss 1311 returns to its original state and cooperates with the assembly hole 121 to limit the cover 131. This makes the removal and installation of the cover 131 more labor-saving.

[0060] In some embodiments of the present invention, Figures 3 to 5 , Figure 8 As shown, third bosses 1311 are formed on at least one side surface of the cover shell 131 , and the third bosses 1311 are spaced apart from each other.

[0061] In this embodiment, at least one side of the cover 131 has a third boss 1311, and the corresponding hole wall of the structural hole 120 has an assembly hole 121 that matches each third boss 1311. During assembly, the cover 131 is pressed into the structural hole 120, and when each third boss 1311 of the cover 131 enters the corresponding assembly hole 121 on the hole wall of the structural hole 120, the cover 131 is assembled in place in the structural hole 120. There is a gap between at least two bosses, so that the cover 131 and the structural hole 120 are more firmly connected after assembly.

[0062] In some embodiments of the present invention, Figure 5 As shown, the thickness of the cover shell 131 gradually increases from one side to the other side, and at least one third boss 1311 is located on the side of the cover shell 131 with a larger thickness.

[0063] It can be seen from the above embodiment that after the cover shell 131 is assembled into the structural hole 120, the first side surface of the cover shell 131 and the surface of the housing 110 are on the same smooth curved surface. In this embodiment, in order to adapt to the outer surface of the housing 110, the thickness of the cover shell 131 gradually increases from one side to the other side, and the depth of the hole wall of the structural hole 120 matching the side with a larger thickness of the cover shell 131 is deeper, and at least one third boss 1311 is located on the side with a larger thickness of the cover shell 131, and the assembly hole 121 is located on the hole wall with a deeper depth of the structural hole 120. The third boss 1311 is provided on the side with a larger thickness of the cover shell 131, and the assembly hole 121 is provided on the hole wall with a deeper depth of the structural hole 120, and the specifications of the third boss 1311 and the assembly hole 121 can be set larger, so that the cover shell 131 is more firmly fixed in the structural hole 120.

[0064] In an alternative embodiment of this embodiment, at least one third boss 1311 is close to a side of the cover shell 131 with a greater thickness.

[0065] In some embodiments of the present invention, Figures 3 to 5 , Figure 8 As shown, the structural hole 120 is a blind hole. A fourth boss 1312 is formed on the second side of the cover shell 131 to force the fourth boss 1312 to abut against the blind end of the structural hole 120 when the cover shell 131 is in the structural hole 120 .

[0066] In this embodiment, the structural hole 120 is a blind hole structure. During the assembly process, the second side of the cover shell 131 is installed toward the structural hole 120, and when the fourth boss 1312 on the second side of the cover shell 131 abuts against the blind end of the structural hole 120, the cover shell 131 is assembled in place in the structural hole 120. The fourth boss 1312 is provided so that when the cover shell 131 is assembled in place in the structural hole 120, there is a gap between the cover shell 131 and the blind end of the structural hole 120, so as to facilitate the removal of the cover shell 131 from the structural hole 120.

[0067] In some embodiments of the present invention, Figure 3 and Figure 5 As shown, the side surface of the mounting anti-detachment portion 133 of the connecting seat 132 is on the same plane as the second side surface.

[0068] As can be seen from the above embodiment, after the screw cap 130 is assembled on the housing 110, the second side surface of the cover 131 faces the blind end of the structural hole 120. In this embodiment, the side surface of the mounting anti-detachment portion 133 of the connecting seat 132 is in the same plane as the second side surface, that is, after the screw cap 130 is assembled on the housing 110, the cover 131 and the connecting seat 132 cover the anti-detachment portion 133, so that the anti-detachment portion 133 is not easy to loosen, and the outer surface of the housing 110 is beautiful.

[0069] In some embodiments of the present invention, Figure 3 , Figure 4 and Figure 6 As shown, the cover 131 is provided with a disassembly opening 1314. When the cover 131 is assembled in the structural hole 120, the disassembly opening 1314 is in the same plane as the housing 110. The provision of the disassembly opening 1314 facilitates the disassembly of the cover 131.

[0070] The embodiment of the utility model further provides an air conditioner, comprising a housing 110 and a screw cap 130 in any of the above embodiments. The housing 110 defines a blind hole-shaped structural hole 120, and defines a screw hole 124 for passing a fastening screw at the blind end of the structural hole 120. The screw cap 130 is disposed in the structural hole 120 and is detachably connected to the housing 110.

[0071] In this embodiment, during the assembly process, the second side surface of the cover 131 is installed toward the structural hole 120, and when the third boss 1311 on the cover 131 is snapped into the corresponding assembly hole 121 on the hole wall of the structural hole 120, and the fourth boss 1312 on the cover 131 abuts against the blind end of the structural hole 120, the cover 131 is assembled in place in the structural hole 120. At this time, the screw cap 130 covers the screw hole 124 defined by the blind end of the structural hole 120, so that the screw in the screw hole 124 will not be exposed to the outside, thereby enhancing the aesthetics of the air conditioner and preventing the loss of the fastening screws.

[0072] As can be seen from the above embodiment, the anti-slip portion 133 is made of elastic material. In this embodiment, when the fastening screw needs to be replaced, it is only necessary to remove the cover 131 and the connecting seat 132 from the structural hole 120, and the rod 1331 of the anti-slip portion 133 can continue to be connected to the housing 110. Applying external force to deform the rod 1331 of the anti-slip portion 133 makes the cover 131 and the connecting seat 132 move away from the structural hole 120, so that the fastening screw can be replaced, which is very convenient.

[0073] In some embodiments of the present invention, Figure 2 and Figure 7As shown, a limiting hole is also defined at the blind end of the structural hole 120, and the limiting hole has a first hole segment 1221, a neck, and a second hole segment 1222 connected in sequence, and at least the opening area of ​​the first hole segment 1221 is larger than the opening area of ​​the second hole segment 1222, so as to facilitate the anti-slip portion 133 of the screw cap 130 to pass through the first hole segment 1221 of the limiting hole, enter the second hole segment 1222 in the radial direction through the neck, and cooperate with the hole edge of the second hole segment 1222. The cross-sectional area of ​​the first boss 1332 on the anti-slip portion 133 perpendicular to its axis is smaller than the opening area of ​​the first hole segment 1221, and the cross-sectional area of ​​the first boss 1332 on the anti-slip portion 133 perpendicular to its axis is larger than the opening area of ​​the second hole segment 1222.

[0074] In the present embodiment, during the assembly process, firstly, one end of the anti-slip part 133 is inserted into the first hole section 1221 with a larger opening area, and the first boss 1332 is passed through the first hole section 1221, and then the anti-slip part 133 is dragged to the second hole section 1222 with a smaller opening area, so that after the anti-slip part 133 enters the second hole section 1222, the connection between the anti-slip part 133 and the housing 110 is completed, and at this time, the housing 110 is stopped at one end of the first boss 1332 close to the connecting seat 132 and the cover shell 131 through the second hole section 1222. The first hole section 1221 with a larger opening area of ​​the limiting hole facilitates the insertion of the anti-slip part 133 and ensures the installation efficiency of the anti-slip part 133. In addition, since the cross-sectional area of ​​the first boss 1332 on the anti-slip part 133 perpendicular to its axis is greater than the opening area of ​​the second hole section 1222, the anti-slip part 133 will not slip out in the second hole section 1222.

[0075] In some embodiments of the present invention, Figure 7 As shown, one of the assembly holes 121 on the hole wall of the structural hole 120 is connected to the first hole segment 1221. Since the first hole segment 1221 is connected to the second hole segment 1222, during the production process, it is convenient for the staff to punch the first hole segment 1221, the second hole segment 1222 and the card slot, which shortens the production time and ensures the production efficiency.

[0076] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 7 As shown, a mounting opening is defined on a hole wall on one side of the structural hole 120 , the mounting opening is communicated with the hole opening of the structural hole 120 , and a reinforcing rib 123 is formed on the edge of at least one side of the mounting opening, and the reinforcing rib 123 is limited and stopped on one side of the screw cap 130 .

[0077] In this embodiment, after the rod 1331 of the anti-detachment portion 133 is connected to the housing 110, the cover 131 with the connection seat installed is pushed into the structural hole 120 through the installation opening, so that the third boss 1311 enters the assembly hole 121, and the reinforcing rib 123 stops at one side of the cover 131, and the assembly is completed. The installation opening facilitates the installation of the screw cap 130. In addition, the provision of the reinforcing rib 123 makes the screw cap 130 more firmly in the structural hole 120 and will not fall out of the installation opening.

[0078] In some embodiments of the present invention, Fig. 9 As shown, two opposite sides of the housing 110 are provided with structural holes 120, and the two structural holes 120 are mirror-imaged, and the screw caps 130 in the two structural holes 120 are also mirror-imaged. The mirror-imaged structural holes 120 and screw caps can make the outer surface of the housing 110 more beautiful.

[0079] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
