The lower bracket limiting nut 150 cooperates with the screw rod and can move up and down relative to the screw rod 140 to adjust the upper and lower relative positions of the lower bracket 120 and the upper bracket 110 .

[0069] Specifically, see Figure 7 The upper bracket 110 has a receiving groove with an opening at the lower end, and a first central through hole 111 penetrating the receiving groove is vertically opened in the center of the upper bracket 110. Figure 6The two sides of the accommodating groove are upper bracket fixing parts 112, and the upper bracket fixing parts 112 are provided with screw mounting holes 1121, which can be fixedly connected to the ceiling electrical appliances by screws.

[0070] The upper part of the lower bracket 120 is arranged in the receiving groove of the upper bracket 110 and can slide axially along the upper bracket 110. A second central through hole 121 is provided on the lower bracket 120 and runs through from top to bottom. The second central through hole 121 is coaxially arranged with the first central through hole 111. The second central through hole 121 is a stepped hole with a smaller top and a larger bottom. Limited slots 122 are provided on both sides of the second central through hole 121.

[0071] The lower bracket limiting nut 150 is supported on the top of the lower bracket 120, and has wings 151 on both sides. The wings 151 are inserted downward into the limiting slots 122, see Fig. 9 , so as to limit the rotation between the lower bracket limit nut 150 and the lower bracket 120 in the axial direction.

[0072] like Figure 8 , the rod portion of the screw rod 140 passes through the second central through hole 121, the lower bracket limiting nut 150 and the first central through hole 111 from bottom to top. Two upper and lower limiting nuts 160 are provided on the upper side of the upper bracket 110 and in the receiving groove, and the upper and lower limiting nuts 160 are connected to the screw rod 140. The screw rod 140 is connected to the upper bracket 110 through the upper and lower limiting nuts 160 to limit the displacement between the screw rod 140 and the upper bracket 110 in the axial direction, that is, there is no upper and lower displacement between the screw rod 140 and the upper bracket 110, and the screw rod 140 can rotate along the axial direction of the upper bracket 110.

[0073] When the screw rod 140 is rotated to adjust, the lower bracket limit nut 150 can move up and down relative to the screw rod 140 , so that the upper bracket 110 can be raised or lowered relative to the lower bracket 120 to adjust the upper and lower relative positions H between the upper bracket 110 and the lower bracket 120 .

[0074] In this embodiment, the horizontal adjustment mechanism includes an adjustment bolt 170 , which passes through the keel bracket 130 and is threadedly engaged with the lower bracket 120 to adjust the horizontal relative position of the keel bracket 130 and the lower bracket 120 .

[0075] Specifically, see 7, the keel bracket 130 includes a supporting body 131, one end of the supporting body 131 has a keel fixing structure, and the other end has a first bending portion 132 that is vertically bent upward, and the first bending portion 132 has a through hole 1321 in the horizontal direction. In addition, a center hole 1311 is provided in the center of the supporting body 131 for the screw rod 140 to pass through and cooperate with the lower bracket 120. Horizontal slide grooves 1312 are provided on both sides of the center hole 1311.

[0076] A threaded hole is provided at the bottom of the lower bracket 120. The adjusting bolt 170 passes through the through hole 1321 and is threadedly engaged with the threaded hole. By rotating and adjusting the adjusting bolt 170, the horizontal relative position between the keel bracket 130 and the lower bracket 120 can be adjusted.

[0077] The bottom end of the lower bracket 120 is also provided with a downwardly protruding protrusion 124 , which is slidably arranged in a horizontal slide groove 1312 of the supporting body 131 , and serves as a sliding guide between the keel bracket 130 and the lower bracket 120 .

[0078] Furthermore, L-shaped second bending portions 133 that are bent vertically upward and then bent horizontally are also provided on both sides of the first bending portion 132 of the keel bracket 130. Correspondingly, the lower sides of the lower bracket 120 have step portions 123, and the second bending portions 133 are pressed on the step portions 123 to limit the displacement of the keel bracket 130 and the lower bracket 120 in the up-and-down direction.

[0079] In this embodiment, see Figure 5 and Figure 6 The keel fixing structure includes a first fixing portion 134 and a second fixing portion 135 .

[0080] The first fixing portion 134 is formed to horizontally extend outward along a middle position of an outer end of the supporting body portion 131 .

[0081] The second fixing portion 135 is formed by bending downward along at least one side edge of the outer end of the supporting body portion 131 and then extending outward horizontally. In this embodiment, two second fixing portions 135 are provided.

[0082] The first fixing portion 134 and the second fixing portion 135 are staggered up and down to form a keel groove a. Fig.11 As shown, the keel groove a is used for clamping and fixing with the triangular keel 12.

[0083] Furthermore, the first fixing portion 134 is provided with a mounting groove b which passes through from top to bottom, and one side of the mounting groove b is open. Fig.12 As shown, the suspension rod 13 is inserted into the installation groove b from one side opening, and is fixedly connected to the first fixing portion 134 through two upper and lower suspension rod nuts 14 .

[0084] Furthermore, the first fixing portion 134 is provided with a mounting hole c extending vertically therethrough. Fig.13 As shown, fasteners such as screws 16 can be fixedly connected to the wooden keel 15 through the mounting holes c.

[0085] The keel bracket 130 has the features of snapping together the keel bracket 130 and the triangular keel 12 , snapping together the keel bracket 130 and the suspension rod 13 , and fixing the keel bracket 130 and the wooden keel 15 , and can adapt to different ceiling electrical appliance installation methods.

[0086] It can be understood that the keel fixing structure of the keel bracket 130 can only adopt one or two or more of the above-mentioned fixing methods.

[0087] When ceiling appliances are installed vertically, Fig.10 As shown, by adjusting the horizontal position of the keel bracket 130, it is ensured that the outer end of the keel bracket 130 (the end with the keel fixing structure) can avoid the keel position.

[0088] See also Figure 1 and Figure 2 as well as Fig.10 The utility model also includes a bathroom heater 200, which includes a bathroom heater host 210, a panel 220 connected to the lower side of the bathroom heater host 210, and the above-mentioned installation accessories 100.

The upper bracket 110 of the installation accessory 100 is fixed in the shell inside the installation opening 211. The keel bracket 130 is arranged horizontally and can be partially or completely retracted into the shell.

[0090] When the bathroom heater main unit 210 is installed vertically, the keel bracket 130 is retracted into the housing of the bathroom heater main unit 210 to ensure that the outer end of the keel bracket 130 can avoid the keel position. After the keel bracket 130 extends outward, it can be fixedly connected to the keel.

[0091] In this embodiment, the bottom of the bathroom heater main unit 210 is the bathroom heater main unit opening 212, which is connected to the panel 220. Under different installation conditions, the bathroom heater main unit opening 212 and the panel 220 can be relatively fitted to reduce the ceiling interlayer wind entering the bathroom heater.

[0092] Take the installation of the triangular keel 12 as an example. Fig.10 As shown, the opening 212 of the bathroom heater main unit is located below the triangular keel 12 , and the width dimension of the opening 212 of the bathroom heater main unit is greater than or equal to the spacing dimension of the triangular keel 12 .
