Background Technology

[0002] Ceiling-mounted air conditioners generally refer to recessed air conditioners installed on the ceiling. They typically have a control panel and an air intake grille connected to it. For easy assembly and disassembly, the air intake grille is usually secured to the control panel using clips. To ensure reliable mounting, traditional methods typically use multiple parts, including screws, for the clips, which impacts production efficiency.

[0003] For example, Chinese patent document CN213019923U discloses an indoor air conditioner unit, including: a housing with an air inlet; a panel at the air inlet with a latch; an air inlet grille on the panel with paired baffles, at least one baffle having a hook facing the other baffle; a latching pin with a sheet-like structure, one end being a latch for detachable connection with the latch, and the other end being a plug that can be inserted between the two baffles, the hook restricting the up-and-down movement of the latching pin, and a slotted hole at the axis of the latching pin; and a fastener passing through the slotted hole to fix the latching pin to the air inlet grille; the fastener in this design is a self-tapping screw.

[0004] Furthermore, Chinese patent document CN222086150U discloses a panel suction grille installation structure, including a locking tongue and a locking structure. One end of the locking tongue is used to limit and fix the suction grille, and the other end is used to insert into a slot on the panel. A positioning structure is also formed in the middle of the locking tongue. The locking structure is disposed on the panel and forms an installation cavity through which the locking tongue passes. The positioning structure is inserted into the locking structure and locked in place. The locking tongue is designed to mainly include a connecting section, a locking tongue pick-up / placement end, and a locking tongue extension end. The connecting section is arranged between the locking tongue pick-up / placement end and the locking tongue extension end, and the locking tongue pick-up / placement end cooperates with the connecting section to abut against the edge of the suction grille. The locking tongue extension end inserts into the slot on the panel for connection. A sliding groove is formed on the connecting section along the sliding direction of the locking tongue during installation or disassembly. A locking element that is detachably and fixedly connected to the panel is disposed in the sliding groove. The locking element in this design is a limiting screw. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a ceiling-mounted air intake grille assembly that is easier to assemble.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a ceiling-mounted air intake grille clamping plate assembly, including an air intake grille and a clamping plate. The clamping plate is installed on the top left side of the air intake grille. A strip-shaped guide hole is provided in the middle of the clamping plate, penetrating its upper and lower surfaces and extending in the left and right directions. The left end of the clamping plate is a plug for docking with the clamping interface on the panel, and the right end is a sliding operating part. Elastic abutment parts are provided on the front and rear sides of the clamping plate, respectively. A guide post and a support block are fixedly provided on the top left side of the air intake grille. The upper end of the guide post has an anti-detachment protrusion. The support block corresponds to the elastic abutment part one by one. The left side of the support block is used to cooperate with the elastic abutment part. The plug has a first state of being detached from the panel and a second state of being connected to the panel. When the clamping plate is in the installed state, the guide post and the strip-shaped guide hole form a sliding fit. The anti-detachment protrusion is located above the strip-shaped guide hole to limit the clamping plate in the upper and lower directions. By moving the clamping plate left and right, the plug can be in the first state of being detached from the panel and then connected to the panel. The system switches between two states. When the plug is in the first state, the elastic contact part is in an elastic deformation state. When the plug is in the second state, the elastic contact part is in a natural state. The left end of the strip guide hole is connected to a snap-fit ​​hole that penetrates the upper and lower surfaces of the plate. The snap-fit ​​hole is constructed to allow the anti-detachment protrusion and guide post to pass through in the vertical direction, and the guide post can move freely in the horizontal direction between the snap-fit ​​hole and the strip guide hole. The lower surface of the plate has an elastic buckle in the right area, and a limit block is fixedly installed in the top area of ​​the left end of the suction grille. When the anti-detachment protrusion and guide post are located in the area of ​​the snap-fit ​​hole, the elastic buckle is located in the right area of ​​the limit block. At this time, by sliding the plate to the left, the snap-fit ​​part of the elastic buckle can contact the limit block, and then the elastic buckle will undergo elastic deformation to switch the snap-fit ​​part of the elastic buckle to the left area of ​​the limit block. When the snap-fit ​​part of the elastic buckle is located in the left area of ​​the limit block, the plate is in the installation state.

[0007] A further preferred embodiment is that the anti-detachment protrusions are symmetrically arranged on the front and rear sides of the guide post; and the upper end of the anti-detachment protrusion is provided with a first guide angle.

[0008] A further preferred embodiment is that the upper end of the support block is provided with a second guide angle.

[0009] A further preferred embodiment is that the snap-fit ​​part of the elastic buckle is provided with a third guide bevel.

[0010] A further preferred embodiment is that the left end of the plug is provided with a fourth guide bevel.

[0011] A further preferred embodiment is that the card plate includes a first plate at the location of the plug and a second plate at the location of the strip guide hole. Both the first and second plates are horizontally arranged, with the first plate positioned higher than the second plate and the two connected as a whole by a middle inclined plate. The upper surface of the first plate is provided with a first strip reinforcing rib extending in the left-right direction, and the lower surface of the second plate is provided with a second strip reinforcing rib extending in the left-right direction. The upper surface of the middle inclined plate is connected to the first and second plates as a whole by a third reinforcing rib, and the lower surface of the middle inclined plate is connected to the first and second plates as a whole by a fourth reinforcing rib. The strip guide hole and the snap-fit ​​hole are integrally formed by a flanged hole structure that protrudes relative to the lower surface of the second plate.

[0012] A further preferred embodiment is that the sliding operation part is a bent edge that is bent downward at 90° relative to the right end of the plate, and the lower end of the bent edge extends beyond the lower surface of the suction grille; the suction port side wall of the suction grille is provided with a positioning notch that matches the sliding operation part, and when the plug is in the second state, the sliding operation part is engaged in the positioning notch.

[0013] A further preferred embodiment is that the top surface of the left end of the suction grille and the lower end of the guide post are fixedly connected as a whole by a support rib, and the support rib and the anti-detachment protrusion work together to limit the vertical movement of the plate.

[0014] A further preferred embodiment is that the outer periphery of the top surface of the suction grille is provided with an annular protrusion, and the left side of the annular protrusion is provided with a connection hole that matches the plug; when the plate is in the installation state, the plug is at least partially inserted into the connection hole.

[0015] Based on the above-mentioned ceiling machine suction grille clamping plate assembly, this utility model also provides a ceiling machine suction grille fixing and installation structure. This utility model also includes a panel with suction grille mounting holes. The left side wall of the suction grille mounting holes is provided with a clamping interface and the right side wall is provided with a hook connection port. A hook is fixedly provided on the right side of the suction grille. The right side of the suction grille is connected to the hook and the hook connection port in a detachable snap-fit ​​connection.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] It should be noted beforehand that the orientations of front, back, left, and right in this utility model are only for the purpose of understanding the technical solution. The orientations will vary depending on the viewing angle. For example, this utility model is described below as "the card plate 20 is installed on the top left side of the suction grille 10", but in reality, the card plate 20 may also be located on the right, front, or back side relative to the suction grille 10.

[0031] like Figures 1 to 11As shown, the ceiling-mounted air intake grille clamping plate assembly of this utility model includes an air intake grille 10 and a clamping plate 20. The clamping plate 20 is installed on the top left side of the air intake grille 10. A strip-shaped guide hole 203 is provided in the middle of the clamping plate 20, penetrating its upper and lower surfaces and extending in the left-right direction. The left end of the clamping plate 20 is a plug 201 for connecting to the clamping interface 301 on the panel 30, and the right end is a sliding operating part 202. Elastic abutment parts 205 are respectively provided on the front and rear sides of the clamping plate 20. The left end of the air intake grille 10... A guide post 101 and a support block 103 are fixedly installed on the top surface area. The upper end of the guide post 101 has an anti-detachment protrusion 102. The support block 103 corresponds one-to-one with the elastic abutment part 205. The left side of the support block 103 is used to cooperate with the elastic abutment part 205. The elastic abutment part 205 can generally be in the form of an elastic lever arm. In some alternative embodiments, it can also be implemented by using a lever arm in conjunction with a spring. The plug 201 has a first state of being detached from the panel 30 and a state of being connected to the panel 30. In the second state, when the locking plate 20 is in the installed state, the guide post 101 and the strip guide hole 203 form a sliding fit. The anti-detachment protrusion 102 is located above the strip guide hole 203 to limit the locking plate 20 in the vertical direction. By moving the locking plate 20 left and right, the plug 201 can switch between the first state and the second state. When the plug 201 is in the first state, the elastic abutment part 205 is in an elastic deformation state. When the plug 201 is in the second state, the elastic abutment part 205 is in a self-deformed state. In this state, the left end of the strip guide hole 203 is connected to a snap-fit ​​hole 204 that penetrates the upper and lower surfaces of the locking plate 20. The snap-fit ​​hole 204 is constructed to allow the anti-detachment protrusion 102 and the guide post 101 to pass through in the vertical direction, and the guide post 101 can move freely in the horizontal direction between the snap-fit ​​hole 204 and the strip guide hole 203. That is, the shape and diameter of the snap-fit ​​hole 204 are matched with the anti-detachment protrusion 102, usually slightly larger than the shape of the anti-detachment protrusion 102 projected onto the horizontal plane. In order to make the limiting structure more reliable, the anti-detachment protrusion 102 in this utility model is symmetrically arranged on the front and rear sides of the guide post 101. Correspondingly, the overall hole shape formed by the snap-fit ​​hole 204 and the strip guide hole 203 is T-shaped. The lower surface of the card plate 20 is provided with an elastic buckle 206 at the right end, and a limit block 104 is fixedly provided on the top left end of the suction grille 10. When the anti-detachment protrusion 102 and the guide post 101 are located in the area of ​​the snap hole 204, the elastic buckle 206 is located in the right side area of ​​the limit block 104. At this time, by sliding the card plate 20 to the left, the snapping part of the elastic buckle 206 can come into contact with the limit block 104, and then the elastic buckle 206 will undergo elastic deformation so that the snapping part of the elastic buckle 206 switches to the left side area of ​​the limit block 104. When the snapping part of the elastic buckle 206 is located in the left side area of ​​the limit block 104, the card plate 20 is in the installation state.When assembling the suction grille 10 and the clamping plate 20, it is only necessary to first align the anti-detachment protrusion 102 and the guide post 101 with the left-side snap-fit ​​hole 204 and insert them. Then, by sliding the clamping plate 20 to the left, the elastic buckle 206 on the lower right side of the plate can be engaged. This makes the operation simpler and can improve production efficiency.

[0032] To facilitate assembly, this utility model adds a series of guide angle structures. For example, the upper end of the anti-detachment protrusion 102 is provided with a first guide angle 105; the upper end of the support block 103 is provided with a second guide angle 106; the buckling part of the elastic buckle 206 is provided with a third guide angle 207; and the left end of the plug 201 is provided with a fourth guide angle 208.

[0033] To improve the overall structural strength of the card plate 20, its preferred embodiment is as follows: the card plate 20 includes a first plate at the location of the plug 201 and a second plate at the location of the strip guide hole 203. Both the first plate and the second plate are horizontally arranged. The first plate is higher than the second plate and the two are connected as a whole by a middle inclined plate. The upper surface of the first plate is provided with a first strip reinforcing rib 209 extending in the left-right direction, and the lower surface of the second plate is provided with a second strip reinforcing rib 210 extending in the left-right direction. The upper surface of the middle inclined plate is connected to the first plate and the second plate as a whole by a third reinforcing rib 211, and the lower surface of the middle inclined plate is connected to the first plate and the second plate as a whole by a fourth reinforcing rib 212. The strip guide hole 203 and the snap-fit ​​hole 204 are a flanged hole structure that protrudes relative to the lower surface of the second plate.

[0034] For ease of operation, the sliding operating part 202 is preferably a bent edge that is bent downwards at 90° relative to the right end of the clamping plate 20, and the lower end of the bent edge extends beyond the lower surface of the suction grille 10. To further improve structural integrity and minimize impact on the suction channel, the suction port sidewall of the suction grille 10 is provided with a positioning notch 108 that matches the sliding operating part 202. When the plug 201 is in the second state, the sliding operating part 202 is engaged in the positioning notch 108.

[0035] To ensure a simple and reliable structure, the top surface of the left end of the suction grille 10 and the lower end surface of the guide post 101 are fixedly connected as a whole by a support rib 107. The support rib 107 and the anti-detachment protrusion 102 cooperate to limit the vertical movement of the clamping plate 20. It is understood that in a design without the support rib 107, the top surface of the suction grille 10 and the anti-detachment protrusion 102 can also directly cooperate to limit the vertical movement of the clamping plate 20.

[0036] To ensure a simple and reliable structure, the outer periphery of the top surface of the suction grille 10 is provided with an annular protrusion 109, and the left side of the annular protrusion 109 is provided with a connection hole 110 that matches the plug 201. When the card plate 20 is in the installation state, the plug 201 is at least partially inserted into the connection hole 110. That is, when the plug 201 is in the first state, the plug 201 retracts to the right into the connection hole 110, and the plug 201 is completely disengaged from the card interface 301; when the plug 201 is in the second state, the left end of the plug 201 extends to the left out of the connection hole 110, and the plug 201 simultaneously connects to both the card interface 301 and the connection hole 110.

[0037] Based on the aforementioned ceiling-mounted air intake grille clamping assembly, this utility model also provides a fixed installation structure for the ceiling-mounted air intake grille. This utility model further includes a panel 30, which has air intake grille mounting holes 302. The left side wall of the air intake grille mounting holes 302 is provided with a snap-fit ​​interface 301, and the right side wall is provided with a hook connection port. A hook 111 is fixedly installed on the right side of the air intake grille 10. The right side of the air intake grille 10 is detachably snap-fit ​​connected to the hook connection port via the hook 111. The left side of the air intake grille 10 is connected to the snap-fit ​​interface 301 via a clamping plate 20. It is understood that the installation principle of this utility model is the same as the prior art: first, the right side of the air intake grille 10 is snapped into position, and then the clamping plate 20 on the left side is used for reliable fixing. The key technical point of this utility model lies in how the clamping plate 20 is specifically assembled with the air intake grille 10. The number of hooks 111 and clamping plates 20 can be flexibly designed according to actual conditions. For example, in the embodiment shown in the attached drawings of this utility model, there are two clamping plates 20 and three hooks 111.
