However, after disassembling the casing, the screw cover will be removed from the casing, and the volume of the screw cover is small, so it is easy to lose the screw cover when the casing is assembled again, which brings a bad user experience. Utility Model Content

[0003] In view of the above problems, the utility model is proposed to provide a screw cover and an air conditioner using the same that overcome the above problems or at least partially solve the above problems, and can solve the problem that the screw cover is easily lost, thereby achieving the effect of preventing the screw cover from being lost.

[0004] Specifically, the utility model provides a screw cover, which is adapted to a structural hole defined on a casing of an air conditioner, is integrally formed of an elastic material, and comprises:

[0005] A cover body portion, configured to be detachably connected to the structural hole;

[0006] The anti-detachment portion is linearly extended and arranged on one side of the cover body portion, and is configured to be connected to the housing so as to present an elastically stretched state at least when the cover body portion is detached from the structural hole.

[0007] Optionally, the first side surface of the cover body is in the shape of a smooth curved surface, so that when the cover body is installed in the structural hole, the first side surface of the cover body and the surface of the housing are on the same smooth curved surface.

[0008] Optionally, the second side surface of the cover body is located on the opposite side of the first side surface, and the root of the anti-detachment portion is arranged on the second side surface.

[0009] Optionally, the anti-detachment portion has a rod portion extending in a straight line, and a first boss is formed at the tip of the rod portion, wherein the first boss is exposed from the periphery of the rod portion to enable the casing to be stopped on the side of the first boss close to the cover body portion when the cover body portion is detached from the structural hole.

[0010] Optionally, at least one second boss protruding from the side is formed on the cover body, and at least one second boss is configured to be snap-connected to a slot defined on the hole wall of the structural hole.

[0011] Optionally, the second bosses are formed on at least two side surfaces of the cover body, and the second bosses are spaced apart from each other.

[0012] Optionally, the thickness of the cover body gradually increases from one side to the other side, and at least one of the second bosses is located on the side of the cover body with greater thickness, or at least one of the second bosses is close to the side of the cover body with greater thickness.

[0013] The utility model also provides an air conditioner, comprising:

[0014] The housing defines a blind hole-shaped structural hole, and defines a screw hole for passing a fastening screw at a blind end of the structural hole;

[0015] The screw cover as described in any one of the above is arranged in the structural hole and is detachably connected to the casing.

[0016] Optionally, a limiting hole is further defined at the blind end of the structural hole, and the limiting hole has a first hole segment, a neck, and a second hole segment connected in sequence, and at least the opening area of ​​the first hole segment is larger than the opening area of ​​the second hole segment, so as to facilitate the anti-slip portion of the screw cover to pass through the first hole segment of the limiting hole, radially enter the second hole segment through the neck, and cooperate with the hole edge of the second hole segment in a limiting manner.

[0017] Optionally, a mounting opening is defined on a hole wall on one side of the structural hole, the mounting opening is communicated with the hole mouth of the structural hole, and a reinforcing rib is formed on the edge of at least one side of the mounting opening, and the reinforcing rib is limited and stopped on one side of the screw cover.

[0018] In the screw cover of the utility model and the air conditioner using the same, since the screw cover is made of an elastic material, the surface of the elastic material is relatively rough, which increases the friction between the screw cover and the structural hole, making it difficult for the cover body to fall out of the structural hole. This is the first guarantee to prevent the screw cover from being lost. Since the anti-falling part is connected to the casing, and the anti-falling part is connected to the cover body, when the screw cover needs to be opened, the cover body will fall out of the structural hole under the action of external force, and the cover body will always be connected to the casing through the anti-falling part. This is the second guarantee to prevent the screw cover from being lost. In summary, the screw cover effectively prevents the screw cover from being lost under the double guarantee.

Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0032] Figure 1 FIG. 1 is a schematic partial structural diagram of a screw cover and an air conditioner using the screw cover according to an embodiment of the utility model, as shown in FIG. Figure 1 As shown, and refer to Figures 2 to 7 The embodiment of the utility model provides a screw cover 130, which is adapted to the structural hole 120 defined on the housing 110 of the air conditioner. The screw cover 130 is integrally formed of an elastic material, and the screw cover 130 includes a cover body 131 and an anti-detachment portion 132. The cover body 131 is configured to be detachably connected to the structural hole 120. The anti-detachment portion 132 is linearly extended and arranged on one side of the cover body 131, and is configured to be connected to the housing 110, so as to be in an elastically stretched state at least when the cover body 131 is detached from the structural hole 120.

[0033] In the screw cover 130 of the embodiment of the utility model, since the screw cover 130 is made of an elastic material, the surface of the elastic material is relatively rough, which increases the friction between the screw cover 130 and the structural hole 120, making it difficult for the cover body 131 to fall out of the structural hole 120. This is the first guarantee to prevent the screw cover 130 from being lost. Since the anti-falling-off portion 132 is connected to the housing 110, and the anti-falling-off portion 132 is connected to the cover body 131, when the screw cover 130 needs to be opened, when the cover body 131 falls out of the structural hole 120 under the action of external force, the cover body 131 will always be connected to the housing 110 through the anti-falling-off portion 132. This is the second guarantee to prevent the screw cover 130 from being lost. In summary, the screw cover 130 effectively prevents the screw cover 130 from being lost under the double guarantee.

[0034] Furthermore, since the screw cover 130 is integrally formed of elastic material, that is, the entire screw cover 130 can be formed by a mold, compared with a separate structure, the production efficiency of the screw cover 130 is greatly improved.

[0035] Furthermore, since the cover body 131 is in an elastically stretched state when it is detached from the structural hole 120, that is, when the cover body 131 is located in the structural hole 120, the anti-detachment portion 132 is in a compressed or folded state or is telescopically inserted, the casing 110 is neat and beautiful, meeting people's aesthetic needs and enhancing market competitiveness.

[0036] During the assembly process, the anti-detachment portion 132 is first connected to the air conditioner housing 110, and the anti-detachment portion 132 is in an extended state. Then the cover portion 131 is pressed into the structural hole 120, and the anti-detachment portion 132 is compressed accordingly until the cover portion 131 is assembled into the structural hole 120.

[0037] In some embodiments of the present invention, Figure 2 and Figure 4 As shown, the first side surface of the cover body 131 is in a smooth curved surface shape, so that when the cover body 131 is installed in the structural hole 120, the first side surface of the cover body 131 and the surface of the housing 110 are on the same smooth curved surface.

[0038] In this embodiment, during assembly, the first side surface of the cover 131 is facing outward, and the opposite surface of the first side surface of the cover 131 is facing the structural hole 120, 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 surface 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.

[0039] In some embodiments of the present invention, Figure 2 and Figure 4 As shown, the first side profile of the cover body 131 is adapted to the outer surface profile of the structural hole 120. After the cover body 131 is assembled in the structural hole 120, the gap between the first side of the cover body 131 and the structural hole 120 is very small, making the outer surface of the casing 110 more beautiful.

[0040] In some embodiments of the present invention, Figures 1 to 3 As shown, the second side surface of the cover body portion 131 is located on the opposite side of the first side surface, and the root of the anti-detachment portion 132 is arranged on the second side surface.

[0041] It can be seen from the above embodiment that after the cover body 131 is installed in the structural hole 120, the first side surface of the cover body 131 is in the same plane as the outer surface of the housing 110. In this embodiment, the second side surface is arranged opposite to the first side surface, that is, the second side surface of the cover body 131 faces the structural hole 120, and the anti-slip portion 132 is arranged on the second side surface, that is, the anti-slip portion 132 is connected to the structural hole 120 of the housing 110. After the cover body 131 is installed in the structural hole 120, the anti-slip portion 132 is compressed or folded in the structural hole 120, so that the anti-slip portion 132 will not be exposed outside the housing 110, further improving the aesthetics of the outer surface of the housing 110 and increasing market competitiveness.

[0042] In some embodiments of the present invention, Figures 1 to 3 As shown, the anti-detachment portion 132 has a rod portion 1321 extending in a straight line, and a first boss 1322 is formed at the tip of the rod portion 1321. The first boss 1322 is exposed from the outer periphery of the rod portion 1321 to enable the housing 110 to be stopped on the side of the first boss 1322 close to the cover body portion 131 when the cover body portion 131 is detached from the structural hole 120.

[0043] In this embodiment, during the assembly process, the first boss 1322 of the rod 1321 is passed through the housing 110, so that the housing 110 is located between the first boss 1322 and the cover 131, and the housing 110 is stopped on the side of the first boss 1322 close to the cover 131. Then the cover 131 is assembled into the structural hole 120. When the cover 131 falls off in the structural hole 120, since the housing 110 is stopped on the side of the first boss 1322 close to the cover 131, the cover 131 can still be connected to the housing 110, thereby preventing the cover 131 from being lost.

[0044] As can be seen from the above embodiment, the screw cover 130 is made of elastic material, that is, the rod 1321 and the first boss 1322 are also made of elastic material. The surface of the elastic material is relatively rough and has a large friction force. After the assembly is completed, the friction force between the anti-detachment part 132 and the housing 110 can be increased, which is more conducive to preventing the anti-detachment part 132 from detaching from the housing 110. In addition, since the rod 1321 of the anti-detachment part 132 extends in a straight line, the structure is very simple. Compared with the special-shaped anti-detachment part 132, the straight-line extending rod 1321 makes installation more convenient.

[0045] In some embodiments of the present invention, Figures 1 to 3 , Figure 6 As shown, at least one second boss 133 protruding from the side is formed on the cover body 131 , and the at least one second boss 133 is configured to be snap-connected in a snap-fitting groove 121 defined on the hole wall of the structural hole 120 .

[0046] In this embodiment, the cover body 131 has a second boss 133, and the corresponding hole wall of the structural hole 120 has a slot 121 that matches the second boss 133. During assembly, the cover body 131 is pressed into the structural hole 120, and when the second boss 133 of the cover body 131 enters the slot 121 on the hole wall of the structural hole 120, the cover body 131 is assembled in place in the structural hole 120. The provision of the second boss 133 and the slot 121 makes the assembly process between the cover body 131 and the structural hole 120 simple, and the assembly is firm and reliable.

[0047] As can be seen from the above embodiments, the second boss 133 is made of elastic material, and the second boss 133 can be elastically deformed. During the installation process, as the distance between the second boss 133 and the hole wall of the structural hole 120 becomes closer and closer, when the second boss 133 contacts the hole wall of the structural hole 120, the second boss 133 is deformed, so that the cover body 131 can continue to move into the structural hole 120. After the second boss 133 enters the slot 121, due to the loss of pressure, the second boss 133 returns to its original state and cooperates with the slot 121 to limit the cover body 131. This makes the removal and installation of the cover body 131 more labor-saving.

[0048] In some embodiments of the present invention, Figure 3 and Figure 6 As shown, second bosses 133 are formed on at least two side surfaces of the cover body 131 , and the second bosses 133 are spaced apart from each other.

[0049] In this embodiment, at least two side surfaces of the cover body 131 are provided with second bosses 133, and the corresponding hole wall of the structural hole 120 is provided with a slot 121 that matches each second boss 133. During assembly, the cover body 131 is pressed into the structural hole 120, and when each second boss 133 of the cover body 131 enters the corresponding slot 121 on the hole wall of the structural hole 120, the cover body 131 is assembled in place in the structural hole 120. There is a gap between at least two second bosses 133, so that the cover body 131 and the structural hole 120 are more firmly connected after assembly.

[0050] In some embodiments of the present invention, Figure 2 and Figure 5 As shown, the thickness of the cover portion 131 gradually increases from one side to the other side, and at least one second boss 133 is located on the side of the cover portion 131 with a larger thickness.

[0051] It can be seen from the above embodiment that after the cover body 131 is assembled into the structural hole 120, the first side surface of the cover body 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 body 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 body 131 is deeper, and at least one second boss 133 is located on the side with a larger thickness of the cover body 131, and the slot 121 is located on the hole wall with a deeper depth of the structural hole 120. The second boss 133 is provided on the side with a larger thickness of the cover body 131, and the slot 121 is provided on the hole wall with a deeper depth of the structural hole 120, and the specifications of the second boss 133 and the slot 121 can be set larger, so that the cover body 131 is more firmly fixed in the structural hole 120.

[0052] In an alternative embodiment of the present embodiment, at least one second boss 133 is close to a side of the cover portion 131 with a greater thickness.

[0053] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, a disassembly opening 135 is provided on the cover body 131. After the cover body 131 is installed in the structural hole 120, the disassembly opening 135 on the cover body 131 is in the same plane as the side wall of the housing 110 where the structural hole 120 is located. In this embodiment, the disassembly opening 135 is provided to facilitate the user to disassemble the cover body 131.

[0054] In some embodiments of the present invention, the elastic material is rubber, and the screw cover 130 is made of rubber. The price of rubber is relatively low, which reduces the production cost of the screw cover 130.

[0055] like Figure 1As shown, the embodiment of the utility model further provides an air conditioner, comprising a housing 110 and a screw cover 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 cover 130 is disposed in the structural hole 120 and is detachably connected to the housing 110.

[0056] 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 second boss 133 on the cover 131 is snapped into the corresponding slot 121 on the hole wall of the structural hole 120, the cover 131 is assembled in place in the structural hole 120. The cover 131 covers the screw hole 124 defined by the blind end of the structural hole 120, so that the screws in the screw hole 124 are not exposed to the outside, thereby enhancing the aesthetics of the air conditioner. In addition, since the structural hole 120 covers the fastening screws in the structural hole 120, the fastening screws are prevented from being lost.

[0057] As can be seen from the above embodiment, the screw cover 130 is made of elastic material. In this embodiment, when the fastening screw needs to be replaced, it is only necessary to remove the cover body 131 from the structural hole 120, and the rod 1321 of the anti-detachment part 132 can continue to be connected to the housing 110. Applying external force to deform the rod 1321 of the anti-detachment part 132 makes the cover body 131 away from the structural hole 120, so that the fastening screw can be replaced, which is very convenient.

[0058] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, a limiting hole is also defined at the blind end of the structural hole 120, and the limiting hole has a first hole section 1221, a neck, and a second hole section 1222 connected in sequence, and at least the opening area of ​​the first hole section 1221 is larger than the opening area of ​​the second hole section 1222, so as to facilitate the anti-slip portion 132 of the screw cover 130 to pass through the first hole section 1221 of the limiting hole, enter the second hole section 1222 in the radial direction through the neck, and cooperate with the hole edge of the second hole section 1222. The cross-sectional area of ​​the first boss 1322 of the anti-slip portion 132 perpendicular to its axis is smaller than the opening area of ​​the first hole section 1221, and the cross-sectional area of ​​the first boss 1322 of the anti-slip portion 132 perpendicular to its axis is larger than the opening area of ​​the second hole section 1222.

[0059] In this embodiment, during the assembly process, firstly, one end of the anti-slip portion 132 is inserted into the first hole section 1221 with a larger opening area, and the first boss 1322 is passed through the first hole section 1221, and then the anti-slip portion 132 is dragged toward the second hole section 1222 with a smaller opening area, so that the anti-slip portion 132 enters the second hole section 1222, and the connection between the anti-slip portion 132 and the housing 110 is completed. At this time, the housing 110 is stopped by the second hole section 1222 at one end of the first boss 1322 close to the cover body 131. The first hole section 1221 with a larger opening area of ​​the limiting hole facilitates the insertion of the anti-slip portion 132, and ensures the installation efficiency of the anti-slip portion 132. Furthermore, since the cross-sectional area of ​​the first boss 1322 of the anti-slip portion 132 perpendicular to its axis is larger than the opening area of ​​the second hole section 1222, the anti-slip portion 132 will not slip out of the second hole section 1222, thereby preventing the cover body 131 connected to the anti-slip portion 132 from falling off.

[0060] In some embodiments of the present invention, Figure 5 As shown, one of the slots 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 slot 121, which shortens the production time and ensures the production efficiency.

[0061] In some embodiments of the present invention, Figure 5 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, the reinforcing rib 123 is limited and stopped on one side of the screw cover 130 .

[0062] In this embodiment, after the rod 1321 of the anti-slip portion 132 is connected to the housing 110, the cover body 131 is pushed into the structural hole 120 through the installation opening so that the second boss 133 enters the slot 121, and the reinforcing rib 123 stops on one side of the cover body 131 to complete the assembly. The installation opening is provided to facilitate the installation of the cover body 131. In addition, the provision of the reinforcing rib 123 makes the cover body 131 more secure in the structural hole 120 and will not fall out of the installation opening. In addition, one side of the screw cover 130 here is the side with a smaller thickness of the cover body 131. It can be seen from the above embodiment that the second boss 133 is provided on the side with a larger thickness of the cover body 131. In this embodiment, the reinforcing rib 123 stops on the side with a smaller thickness of the cover body 131, so that the sides with a larger thickness and a smaller thickness of the cover body 131 have a fixed structure, further making the cover body 131 more stable in the structural hole 120.

[0063] In some embodiments of the present invention, Figure 7 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 covers 130 in the two structural holes 120 are also mirror-imaged. The mirror-imaged structural holes 120 and screw covers 130 can make the outer surface of the housing 110 more beautiful.

[0064] 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.
