The remote control needs to be used with a signal receiving box. For duct air conditioners controlled by a remote control, during the installation of the duct air conditioner, the installer generally directly places the signal receiving box in the return air box of the unit. Since the air outlet of the return air box of the unit is provided with blades, the blades will block the signal receiving box from receiving the signal of the remote control, affecting the user experience.

[0003] The signal receiving box is installed on the ceiling and exposed on the ceiling, so as to avoid the problem that the signal of the remote controller is blocked. Since the existing signal receiving box has no structure for being installed on the ceiling, there is a problem of how to quickly and stably install the signal receiving box on the ceiling.

[0025] The utility model will be further described below in conjunction with the accompanying drawings.

[0026] The first subject of the utility model is a signal receiving box, which is used in conjunction with a remote controller, for example, specifically used in conjunction with a remote controller of a duct machine. Figures 1 to 4 The signal receiving box includes a box body 1, a card plate 2 and a fastening member. The box body 1 includes a bottom plate 11 and a side plate 12 located on one side of the plane where the bottom plate 11 is located. The plane corresponding to the bottom plate 11 and the plane corresponding to the side plate 12 are perpendicular to each other. The bottom plate 11 and the side plate 12 are fixedly connected or the bottom plate 11 and the side plate 12 are integral. The side plate 12 of the box body 1 can be a flat plate or a curved plate. Each side plate 12 can be connected as a whole or arranged at intervals without being directly connected. For example, see Figure 1 and Figure 2 The bottom plate 11 is rectangular, and there are four side plates 12. The lengths of the four side plates 12 in the direction perpendicular to the plane corresponding to the bottom plate 11 are the same, and the outer contours of the four side plates 12 are rectangular. In order to prevent the box body 1 from jumping upward from the mounting hole of the ceiling 7 after the box body 1 is installed in the mounting hole of the ceiling 7, the bottom plate 11 forms a circle of hanging platforms around the side plates 12, that is, the size of the bottom plate 11 is larger than the size of the bottom surface of the columnar structure surrounded by the side plates 12. For example, Figure 1 and Figure 2 In the illustrated embodiment, the length and width of the rectangular bottom plate 11 are respectively greater than the length and width of the cuboid formed by the four side plates 12. In addition, a circle of convex ridges may be provided on the outer periphery of the side plates 12 and close to the bottom plate 11, and a circle of hanging platforms parallel to the plane where the bottom plate 11 is located may be formed on the side of the convex ridges facing away from the bottom plate 11. At this time, after the box body 1 is installed to the installation hole of the ceiling 7, the part between the convex ridges and the bottom plate 11 is suspended on the bottom surface of the ceiling 7. The hanging platforms can not only prevent the box body 1 from jumping upward from the installation hole of the ceiling 7, but also play a role in shielding the edge of the installation hole.

[0027] Two groups of hooks are arranged on one side of the side plate 12 of the box body 1 away from the bottom plate 11. The two groups of hooks have the same structure. The hooks in the same group are composed of two oppositely arranged clips 13, and an inverted T-shaped slot is formed between the two clips 13 of the hooks in the same group, and the opening of the slot faces the direction away from the bottom plate 11. The card board 2 is clamped in the slots of the two groups of hooks, and the two ends of the card board 2 are located outside the side plate 12, and the distance between the two ends of the card board 2 is greater than the spacing between the two groups of hooks.

[0028] The clip 13 itself is elastic, so the card board 2 can be inserted into the card slot by squeezing the clip 13. The card slot is in an inverted T-shape, and the card board 2 is inserted into the position corresponding to the horizontal part of the T-shape. The vertical part of the T-shape corresponds to two clips 13 to prevent the card board 2 from falling out. In order to make the clip 13 of the hook have sufficient elasticity so that the card board 2 can be inserted into the card slot, a notch is set on the side of the clip 13 facing away from the card slot, such as Figure 1 and Figure 2 As shown. In order to ensure that the card plate 2 fixes the box body 1, the two groups of hooks are respectively located between the two side plates 12 arranged opposite to each other, that is, the card plate 2 passes through the center of the box body 1. The two ends of the card plate 2 are movably installed with top tightening members, which abut against the top surface of the ceiling 7 to prevent the box body 1 from falling down from the mounting hole of the ceiling 7. The top tightening member and the hanging platform cooperate with each other to firmly fix the box body 1 at the mounting hole of the ceiling 7. The top tightening member is movably installed at the end of the card plate 2, and the top tightening member can be adjusted to a position abutting against the top surface of the ceiling 7, or to a position that does not affect the installation of the box body 1 into the mounting hole of the ceiling 7. The top tightening member can be displaced in a direction perpendicular to the plane corresponding to the bottom plate 11 through movement, and the end of the top tightening member close to the hanging platform can be moved to a position between the plane corresponding to the hanging platform and the plane corresponding to the card plate 2.

[0029] In order to facilitate the accurate insertion of the card plate 2 into the card slot, the card plate 2 is divided into three sections along its length direction, namely, the middle section and the end sections at both ends of the middle section. The planes corresponding to the two end sections are parallel to the planes corresponding to the middle section. The length of the middle section is consistent with the distance between the two sets of hooks. The top clamp is movably installed on the end section. In order for the top clamp to be able to contact the ceiling 7 with a small displacement in the direction perpendicular to the plane corresponding to the bottom plate 11, the distance between the middle section of the card plate 2 and the hanging platform is greater than the distance between the end sections of the card plate 2 and the hanging platform. Figure 3 and Figure 4 shown.

[0030] Three specific embodiments of the tightening member are provided below.

[0031] Solution 1: The tensioning member is an elastic sheet, and the two ends of the elastic sheet are respectively a first end and a second end. The first end of the elastic sheet is rotatably mounted on the side of the card plate 2 that is opposite to the bottom plate 11. The elastic sheet is made of an elastic material, generally made of a metal material. The elastic sheet has two states and can be adjusted by rotation. The first state is that the second end of the elastic sheet is located on the side of the card plate 2 that is opposite to the bottom plate 11. At this time, the elastic sheet will not abut against the ceiling 7, which facilitates the card plate 2 to be inserted into the card slot. The second state is that the second end of the elastic sheet is located between the plane corresponding to the hanging platform and the plane corresponding to the card plate 2. At this time, the elastic sheet can abut against the ceiling 7. In order to prevent the second end of the elastic sheet from damaging the ceiling 7, the second end is in a sheet shape or is provided with a protective cover to increase the contact area between the second end and the ceiling 7.

[0032] Solution 2: The tensioning member is a bolt, and matching screw holes are respectively provided at both ends of the card plate 2, and the movement direction of the bolt in the screw hole is perpendicular to the plane corresponding to the bottom plate 11. By turning the bolt, the distance between the end of the bolt pointing to the hanging platform and the hanging platform can be adjusted, so that the card plate 2 and the tensioning member can be in a state that is easy to be inserted into the slot, or in a state where the bolt is in contact with the ceiling 7. In order to prevent the bolt from breaking through the ceiling 7, an enlarged end or a protective cover 6 is provided at the end of the bolt pointing to the bottom plate 11 to increase the contact area between the bolt and the ceiling 7. In order to facilitate the rotation of the adjustment bolt, a rotating handle can be provided at the end of the bolt facing away from the bottom plate.

[0033] Option 3 Figure 1 , 3 As shown in and 4. Through holes are respectively provided at both ends of the card plate 2. The through holes are smooth holes. A pull rod 3 is passed through the through holes. The pull rod 3 can move along the direction of the through holes. A spring 4 is passed through the outside of the pull rod 3. A lower limit member 5 is fixedly provided at one end of the pull rod 3 pointing to the bottom plate 11. The spring 4 is located between the lower limit member 5 and the card plate 2. Both ends of the spring 4 are limited by the lower limit member 5 and the card plate 2, respectively. In order to simplify the structure of the lower limit member 5 and reduce the difficulty of assembly, the lower limit member 5 is a nut, and an external thread matching the nut is provided at a section of the pull rod 3 pointing to the bottom plate 11. In order to prevent the lower limit member 5 from breaking through the ceiling 7, a protective cover 6 is provided on the outside of the lower limit member 5. For example, the protective cover is a rubber cover. In order to make the combination between the lower limit member 5 and the protective cover 6 more firmly, a toothed structure is provided on the outside of the lower limit member 5, such as Figure 4 shown.

[0034] An upper limit member 31 is fixedly provided at one end of the pull rod 3 away from the base plate 11. The size of the upper limit member 31 is larger than the size of the through hole of the card plate 2. For example, the upper limit member 31 is a circle of rings fixed to the outside of the pull rod 3. Pull the pull rod 3 in the direction away from the base plate 11, and the spring 4 is compressed between the lower limit member 5 and the card plate 2 to prevent the pull rod 3 from affecting the operation of inserting the card plate 2 into the slot. Release the pull rod 3, and the spring 4 pushes the lower limit member 5 and the card plate 2, so that the protective cover 6 can abut against the ceiling 7. In order to facilitate the lifting of the pull rod 3, a pull handle 32 is provided at the end of the pull rod 3 away from the base plate 11. The pull handle 32 is perpendicular to the pull rod 3, and the upper limit member 31 is located between the pull handle 32 and the card plate 2.

[0035] The second subject of the utility model is the installation structure of the signal receiving box on the ceiling. Figures 1 to 4As shown, the mounting structure of the signal receiving box on the ceiling includes a ceiling 7 and the signal receiving box described in the first subject above. The ceiling 7 is provided with a mounting hole that is consistent with the shape formed by the side panels 12. The bottom surface of the ceiling 7 is located in the hanging platform. The card plate 2 is located above the ceiling 7, and the end of the top fastener close to the hanging platform abuts against the top surface of the ceiling 7. The ceiling 7 is generally a gypsum board. The shape of the mounting hole of the ceiling 7 is consistent with the shape formed by the side panels 12 of the box body 1, and is generally a rectangular hole. When the signal receiving box is used in conjunction with the remote control of the duct machine, the signal receiving box is generally arranged next to the air outlet grille of the duct machine.
