DETAILED DESCRIPTION

[0027] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0028] Embodiment 1

[0029] like Figures 1 to 3 As shown, a keel frame fixing device includes a panel 101, and a connection hole 1011 is provided on the panel 101; the two sides of the panel 101 extend downward to form a mounting plate 102, and a clamping space is formed between the mounting plates 102 on both sides; the panel 101 and the mounting plates 102 on both sides surround to form a clamping structure; and a fixing member is provided on the mounting plate 102. When the fixing device is fixed to the keel frame profile 3, the keel frame profile is clamped in the clamping space between the mounting plates 102 on both sides, and then the keel frame profile 3 is fixed by the fixing member.

[0030] The fixing member is a protrusion 1021 and / or a fixing hole 1022. In this embodiment, the protrusion 1021 and the fixing hole 1022 are used in combination.

[0031] The mounting plate 102 is arranged vertically on the panel 101 and has a square structure, which is conducive to clamping the keel frame profile 3; Figure 2 As shown, the protrusion 1021 protrudes inward on the inner side of the mounting plate 102. The keel frame profile 3 used in this embodiment is provided with grooves 301 on both sides. This embodiment is suitable for connecting with a thicker keel frame profile 3. Pressing from top to bottom on the keel frame profile 3 makes the protrusion 1021 engage with the groove 301, and then using screws to pass through the fixing holes 1022 to press against the keel frame profile 3. With the double fixation of the two, the connection with the keel frame profile 3 is more firm and stable.

[0032] It also includes an installation component 2, which includes a screw sleeve 201, and the screw sleeve 201 is internally threaded with a screw rod 202 (the screw rod 202 has an external thread, the screw sleeve 201 has an internal thread, and the screw rod 202 and the screw sleeve 201 are matched with each other through the external thread and the internal thread), the screw rod 202 is movably inserted in the connecting hole 1011, the screw rod 202 is threadedly connected with a clamping component, the clamping component is located below the screw sleeve 201, and the panel 101 is fixed between the clamping components, wherein the top of the screw rod 202 is connected to the roof, and the fixing device is fixedly connected to the keel frame profile 3, and the upper and lower moving space of the panel 101 on the screw rod 202 is adjusted by twisting the screw sleeve 201 and the clamping component, so that the distance between the keel frame profile 3 and the indoor roof can be adjusted at will according to the installation requirements, and the structure is stable and highly flexible.

[0033] Specifically, Figures 2 to 6 As shown, the clamping assembly includes two first nuts 203 and a second nut 204 (the first nut 203 and the second nut 204 are threadedly connected to the screw rod 202), the first nut 203 is arranged above the second nut 204, and a gasket 205 and a spring gasket 206 are arranged between the first nut 203 and the screw sleeve 201. The gasket 205 increases the contact area, reduces the pressure and protects the parts. The spring gasket 206 has a certain anti-loosening ability and can enhance the tightness of the gasket 205 and the first nut 203.

[0034] The screw rod 202 is inserted into the connecting hole 1011, and the panel 101 is fixedly clamped between the first nut 203 and the second nut 204. After the fixing device is fixedly connected to the keel frame profile 3, when it is necessary to adjust the height of the keel frame profile 3, taking the downward adjustment of the height as an example, first loosen the second nut 204 downward to allow the panel 101 to have space to move downward, and then when the panel 101 moves downward and stops on the second nut 204, the two first nuts 203 are screwed downward to clamp the panel 101, and finally the screw sleeve 201 is screwed downward to press the gasket 205 and the spring gasket 206 against the first nut 203; conversely, when the keel frame profile 3 needs to be adjusted to move upward, first screw the screw sleeve 201 upward, and then screw the two first nuts 203 upward to allow the panel 101 to have space to move upward, and finally screw the second nut 204 upward and tighten it.

[0035] The side edge of the panel 101 extends upward to form a reinforcing plate 103 , which has the function of increasing the strength of the entire panel 101 .

[0036] A first arc position 1012 is provided at the corner of the panel 101, and second arc positions 1031 are provided at both ends of the reinforcing plate 103. The first arc position 1012 and the second arc position 1031 can effectively prevent the operator from being scratched by collision during installation, thereby protecting the operator.

[0037] Embodiment 2

[0038] like Figure 7 As shown, this embodiment is an improvement on the basis of the first embodiment. The improvement of this embodiment is that the protrusion 1021 is located below the fixing hole 1022. This embodiment is suitable for connection with a thinner keel frame profile 3. The fixing device is pressed from top to bottom on the keel frame profile 3, and a screw is passed through the fixing hole 1022 to rest on the keel frame profile 3, while the protrusion 1021 is clamped with the groove 301. With the double fixation of the two, the connection with the keel frame profile 3 is more firm and stable.

[0039] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
