Description

Technical Field

[0001] The invention relates to the technical field of air conditioners, and in particular to a screw cover mounting structure and an air conditioner. Background Art

[0002] The screw cover is usually set at the position where the housing and frame of the wall-mounted air conditioner indoor unit are fixed to cover the screws and screw holes to achieve an aesthetic effect. In addition, the air guide plate rotating arm of the air conditioner wall-mounted unit with a retractable and rotatable air guide plate is often adjacent to the position of the screw cover. The edge of the existing screw cover close to the air guide plate connecting bracket is generally flat. In order to avoid interference with the air guide plate connecting bracket, the size of the screw cover is small and cannot well cover the screws and screw holes.

[0003] In the prior art, there is a patent named "a sliding screw cover structure for an air conditioner". By forming an avoidance groove on the edge of the screw cover close to the rotating arm, a larger screw cover can be set to completely cover the screw. At the same time, the avoidance groove on the screw cover provides an avoidance space for the rotation of the rotating arm, and will not interfere with the rotation of the rotating arm, thereby ensuring the smooth rotation of the rotating arm. However, when the screw cover is slid open, the screw cover slides in a direction perpendicular to the length of the air outlet and needs to be removed after sliding, resulting in chaos at the disassembly and installation site. The screw cover is easily lost during the disassembly and installation process. Summary of the invention

[0004] In view of this, the present invention aims to provide a screw cover installation structure and an air conditioner to solve the problems existing in the prior art.

[0042] like Figure 2 As shown, the screw cover 1 includes a body 12 and sliding structures 11 arranged on both sides of the body 12 , a slide rail 21 is arranged on the mounting portion 2 , and the screw cover is slidably mounted on the slide rail 21 of the mounting portion 2 through the sliding structure 11 .

[0043] like Figures 3-4 As shown, the mounting portion 2 includes a mounting groove 22 and a slide rail 21. A screw hole is provided inside the mounting groove 22, and the middle frame 3 is fixedly connected to the base through the screw hole. The setting of the mounting groove 22 facilitates the installation and removal of the screws. The slide rail 21 is provided outside the mounting groove 22, and the slide rail 21 is parallel to the direction of the length of the air outlet, so that the screw cover 1 can slide in a direction parallel to the length of the middle frame 3, and avoid the connection bracket after sliding open, and the screw cover 1 will not be detached from the middle frame 3 after sliding open, so as to prevent the screw cover from being lost. The slide rail 21 includes a first rail 211 and a second rail 212. The first rail 211 is arranged on both sides of the outside of the mounting groove 22, and the second rail 212 is arranged on an extension line of the first rail 211 away from one end of the connecting bracket 4, and the recessed depth of the second rail 212 is smaller than that of the first rail 211. The first rail 211 and the second rail 212 are arranged on the same line, and an inclined transition portion 213 is arranged between the first rail 211 and the second rail 212, which is used to guide the screw cover 1 to slide between the first rail 211 and the second rail 212, so that the screw cover 1 slides more smoothly.

[0044] A first notch 214 and a second notch 215 are respectively provided at both ends of the first track 211, and a first bottom plate 216 is provided between the first notch 214 and the second notch 215. The first bottom plate 216 is used to support the screw cover 1, and the upper surface of the first bottom plate 216 is lower than the upper surface of the bottom plate of the second track 212. The second notch 215 is provided adjacent to the transition portion 213, and when the screw cover 1 slides onto the first track 211, the provision of the first notch 214 and the second notch 215 enables the screw cover 1 to be stably connected to the mounting portion 2.

[0045] The sliding structure 11 includes a first protrusion 111 and a second protrusion 112, which are arranged on the same line extending along the side of the screw cover 1. The first protrusion 111 and the second protrusion 112 are perpendicular to the body 12 of the screw cover 1 and extend downward. A third notch 113 is arranged between the first protrusion 111 and the second protrusion 112, and the third notch 113 corresponds to the first bottom plate 216 of the first track 211. The first protrusion 111 corresponds to the first notch 214, and the second protrusion 112 corresponds to the second notch 215.

[0046] Preferably, a finger pressure portion 121 and a friction portion 122 are provided on the upper surface of the main body 12 of the screw cover 1. The finger pressure portion 121 is provided to facilitate pressing and lifting the screw cover upward with fingers when sliding the screw cover 1, and the friction portion 122 is provided to facilitate sliding the screw cover left and right, thereby improving the installation sliding efficiency of the screw cover 1.

[0047] When the screw cover needs to be opened, hold the finger pressure parts at both ends of the screw cover tightly and lift the screw cover upward so that the first protrusion 111 is disengaged from the first notch 214 and the second protrusion 112 is disengaged from the second notch 215, and slide the screw cover in the direction away from the connecting bracket 4 until the sliding structures 11 on both sides of the screw cover 1 are located on the second track 212 and the screw cover is in an open state.

[0048] When the screw cover needs to be closed, slide the screw cover toward the connecting bracket 4 until the first protrusion 111 slides to the first notch 214, and press downward until the first protrusion is buckled into the first notch 214 and the second protrusion 112 is buckled into the second notch 215, and the screw cover is in a closed state.

[0049] The screw cover installation structure provided in this embodiment can slide the screw cover on the middle frame of the air conditioner. After the screw cover is installed, it can not only completely cover the screws, making the overall design of the air conditioner more beautiful and providing good protection for the screws, but also the screw cover can avoid the air guide plate connecting bracket after sliding along the length direction of the air outlet, while exposing the screw disassembly part, which is convenient for disassembly and installation.

[0050] Example 2

[0051] like Figures 1-2 and Figures 5-6 As shown, this embodiment further improves the slide rail 21 of the mounting portion 2 on the basis of the embodiment 1. The structure of the screw cover 1 in this embodiment is completely the same as that in the embodiment 1, and will not be repeated here.

[0052] The screw cover 1 includes a body 12 and sliding structures 11 arranged on both sides of the body 12 . A slide rail 21 is arranged on the mounting portion 2 . The screw cover is slidably mounted on the slide rail 21 of the mounting portion 2 through the sliding structure 11 .

[0053] The slide rail 21 includes a first track 211 and a second track 212, and the first track 211 is arranged on both sides of the interior of the mounting groove 22. The first track 211 includes a rib plate 217 for supporting the screw cover 1, and the rib plate 217 is connected to the inner walls on both sides of the mounting groove 22, and the rib plate 217 extends parallel to the mounting plate 5 in a direction close to the center of the mounting groove 22. The length of the rib plate 217 is less than the length of the mounting groove 22, and a first notch 214 and a second notch 215 are formed at both ends of the rib plate 217, respectively, and the first notch 214 and the second notch 215 are respectively matched with the first protrusion 111 and the second protrusion 112 on the screw cover.

[0054] The second track 212 is arranged on the extension line of the first track 211 away from the end of the connecting bracket 4. The upper surface of the rib plate 217 is lower than the upper surface of the bottom plate of the second track 212. An inclined transition portion 213 is arranged between the first track 211 and the second track 212 to guide the sliding of the screw cover 1 between the first track 211 and the second track 212, so that the screw cover 1 can slide more smoothly. The transition portion 213 is arranged adjacent to the second notch 215. When the screw cover 1 slides onto the first track 211, the arrangement of the first notch 214 and the second notch 215 enables the screw cover 1 to be stably connected to the mounting portion 2.

[0055] When the screw cover needs to be opened, hold the finger pressure parts at both ends of the screw cover tightly and lift the screw cover upward so that the first protrusion 111 disengages from the first notch 214 upward, and the second protrusion 112 disengages from the second notch 215 upward, and slide the screw cover in the direction away from the connecting bracket 4. At this time, the first protrusion 111 slides on the rib plate 217, and the second protrusion 112 slides in the second track 212 through the transition part 213, until the sliding structure 11 on both sides of the screw cover 1 is located on the second track 212, and the screw cover is in an open state.

[0056] When the screw cover needs to be closed, slide the screw cover in the direction close to the connecting bracket 4 until the first protrusion 111 slides to the position of the first notch 214, and press it downward until the first protrusion is buckled into the first notch 214, the second protrusion 112 is buckled into the second notch 215, and the third notch 113 corresponds to the rib 217 of the first track 211, and the screw cover is in a closed state.

[0057] Preferably, support blocks 221 are provided at both ends of the installation groove 22 perpendicular to the first track 211 , and the support blocks 211 are used to further support the screw cover 1 .

[0058] The screw cover installation structure provided in this embodiment has slide rails arranged on the inner side and extension line of the installation groove. When the screw cover is installed on the installation groove, it can not only completely cover the screws, but also form a sealed structure to ensure the flatness of the exterior. After the screw cover slides along the length direction of the air outlet, it can avoid the air guide plate connecting bracket and expose the screw disassembly part, which is convenient for disassembly and installation.

[0059] Example 3

[0060] like Figures 1-2 and Figures 7 to 9 As shown, this embodiment further improves the slide rail 21 of the mounting portion 2 on the basis of Embodiment 2. The structure of the screw cover 1 described in this embodiment is completely the same as that of the screw cover in Embodiment 1 and Embodiment 2, and will not be repeated here.

[0061] The screw cover 1 includes a body 12 and sliding structures 11 arranged on both sides of the body 12 . A slide rail 21 is arranged on the mounting portion 2 . The screw cover is slidably mounted on the slide rail 21 of the mounting portion 2 through the sliding structure 11 .

[0062] The slide rail 21 includes a first track 211 and a second track 212. The first track 211 is arranged on both sides of the interior of the mounting groove 22. The first track 211 includes a rib plate 217 and a baffle plate 218. The rib plate 217 is connected to the inner walls of both sides of the mounting groove 22, and the rib plate 217 extends parallel to the mounting plate 5 in the direction close to the center of the mounting groove 22. The baffle plate 218 is connected to the side of the rib plate 217 close to the center of the mounting groove 22, and the baffle plate 218 is perpendicular to the rib plate 217 and extends upward. The rib plate 217 is used to support the screw cover 1, and the baffle plate 218 is used to prevent the screw cover 1 from leaving the track when sliding along the first track 211, and plays a role in limiting and guiding the sliding of the screw cover. The length of the rib plate 217 and the baffle plate 218 is less than the length of the mounting groove 22. The first notch 214 and the second notch 215 are respectively formed at both ends of the rib plate 217. The first notch 214 and the second notch 215 are respectively matched with the first protrusion 111 and the second protrusion 112 on the screw cover.

[0063] like Fig. 9 As shown, preferably, the length of the baffle 218 can also be set to be equal to the length of the mounting groove 22, so that the first notch 214 and the second notch 215 form a closed structure on all sides. After the screw cover 1 is installed on the mounting groove, it is prevented from sliding, thereby ensuring the connection stability between the screw cover and the mounting groove.

[0064] The second track 212 is arranged on the extension line of the first track 211 away from the end of the connecting bracket 4. The upper surface of the rib plate 217 is lower than the upper surface of the bottom plate of the second track 212. An inclined transition portion 213 is arranged between the first track 211 and the second track 212 to guide the sliding of the screw cover 1 between the first track 211 and the second track 212, so that the screw cover 1 can slide more smoothly. The transition portion 213 is arranged adjacent to the second notch 215. When the screw cover 1 slides onto the first track 211, the arrangement of the first notch 214 and the second notch 215 enables the screw cover 1 to be stably connected to the mounting portion 2.

[0065] When the screw cover needs to be opened, hold the finger pressure parts at both ends of the screw cover tightly and lift the screw cover upward so that the first protrusion 111 disengages from the first notch 214 upward, and the second protrusion 112 disengages from the second notch 215 upward, and slide the screw cover in the direction away from the connecting bracket 4. At this time, the first protrusion 111 slides on the rib plate 217, and the second protrusion 112 slides in the second track 212 through the transition part 213, until the sliding structure 11 on both sides of the screw cover 1 is located on the second track 212, and the screw cover is in an open state.

[0066] When the screw cover needs to be closed, slide the screw cover in the direction close to the connecting bracket 4 until the first protrusion 111 slides to the position of the first notch 214, and press it downward until the first protrusion is buckled into the first notch 214, the second protrusion 112 is buckled into the second notch 215, and the third notch 113 corresponds to the rib 217 of the first track 211, and the screw cover is in a closed state.

[0067] The provision of the baffle 218 can effectively prevent the first protrusion 111 from detaching from the first track 211 during the sliding process of the screw cover.

[0068] Preferably, support blocks 221 are provided at both ends of the installation groove 22 perpendicular to the first track 211 , and the support blocks 211 are used to further support the screw cover 1 .

[0069] The screw cover installation structure provided in this embodiment has a slide rail arranged on the inner side and extension line of the installation slot. When the screw cover is installed on the installation slot, the screw can be completely covered. After the screw cover slides along the length direction of the air outlet, the air guide plate connection bracket can be avoided, and the screw removal part is exposed, which is convenient for removal and installation. The rib plate and the baffle can effectively prevent the screw cover from detaching from the slide rail during the sliding process, and play a role of limiting and guiding the sliding installation of the screw cover.
