Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1 to 4As shown, this utility model provides a cleanroom ceiling blind plate fixing structure, including an FFU keel 1, an adjuster 2 and a blind plate fixing clip 4 installed on the top of the FFU keel 1, a ceiling blind plate 8 placed inside the FFU keel 1, the FFU keel 1 including four keel bodies 11 connected end to end, a limiting groove 14 opened on the top of the keel body 11, and a limiting slot 13 connected to the bottom of the limiting groove 14 opened inside the keel body 11, the inner cavity size of the limiting slot 13 is larger than the inner cavity size of the limiting groove 14; due to the setting of the blind plate fixing clip 4, the installation is convenient and the construction efficiency is improved, and when the bottom of the ceiling blind plate 8 is subjected to longitudinal impact after installation, it can also be well buffered by the deformation of the fixing clip body 41 and the positioning spring 45, avoiding the damage of the ceiling blind plate 8, thereby effectively extending its service life;
[0024] The blind plate fixing clip 4 includes a fixing clip body 41 that is clipped onto the top of the keel body 11. A limiting slide rod 42 is movably sleeved in the middle of the fixing clip body 41. The bottom of the limiting slide rod 42 passes through the limiting slide groove 14 and extends into the interior of the limiting slot 13 and is fixedly connected to a positioning block 43. The top of the limiting slide rod 42 passes through the fixing clip body 41 and is fixedly connected to a positioning knob 44. A positioning spring 45 is provided on the outside of the limiting slide rod 42, which abuts against the fixing clip body 41 and the positioning knob 44. Due to the setting of the positioning spring 45, the ceiling blind plate 8 can be quickly pressed by the fixing clip body 41 and the buffer pressure plate 46 under the action of its elastic restoring force, avoiding complicated bolt tightening work, thereby effectively improving the efficiency of building construction.
[0025] like Figure 2 and Figure 3 As shown, the side of the main body 11 of the keel has two blind plate overlapping pieces 12 integrally formed on the left and right sides. The four sides of the ceiling blind plate 8 overlap the top of the blind plate overlapping piece 12. Due to the setting of the blind plate overlapping piece 12, it is not only convenient to install the ceiling blind plate 8, but also provides sufficient adjustment space for the installation of the ceiling blind plate 8, avoiding the situation where the ceiling blind plate 8 is difficult to put into the unit frame due to narrow space and installation errors.
[0026] like Figure 2 and Figure 3As shown, both ends of the limiting slot 13 and the limiting slide groove 14 extend to both ends of the keel body 11. A connecting slot 15 is provided at both ends of the keel body 11. A fastening sleeve 16 is integrally formed inside the connecting slot 15. A two-way connector 5, a three-way connector 6, or a four-way connector 7 is connected between two adjacent keel bodies 11. The two ends of the two-way connector 5, the three-way connector 6, or the four-way connector 7 are inserted into the interior of the connecting slot 15. The two ends of the two-way connector 5, the three-way connector 6, and the four-way connector 7 are fixedly connected to the fastening sleeve 16 by bolts. Due to the setting of the connecting slot 15, it can not only improve the pre-connection function for the connection of two adjacent keel bodies 11, but also ensure that the bolt holes on the two-way connector 5, the three-way connector 6, and the four-way connector 7 can be quickly aligned with the fastening sleeve 16, further improving the convenience and efficiency of installation.
[0027] like Figure 1 and Figure 2 As shown, the bottom of the adjuster 2 is fixedly connected to the top of the keel body 11, and the top of the adjuster 2 is connected to the lifting screw rod 3 by bolts.

Due to the setting of the lifting screw rod 3, the ceiling blind plate 8 can be firmly suspended on the roof with the help of the adjuster 2, the FFU keel 1 and the blind plate fixing clamp 4. At the same time, the bolts connected to the adjuster 2 and the lifting screw rod 3 also facilitate the adjustment of the overall height of the FFU keel 1, the adjuster 2 and the ceiling blind plate 8, thereby ensuring the flatness of the entire ceiling.
[0028] like Figure 4 As shown, the major axis of the positioning block 43 is larger than the outer diameter of the limiting slide rod 42, the minor axis of the positioning block 43 is the same as the outer diameter of the limiting slide rod 42, the minor axis of the positioning block 43 is matched with the minor axis of the inner cavity of the limiting slide groove 14, and the major axis of the positioning block 43 is smaller than the minor axis of the limiting slot 13. Since the minor axis of the positioning block 43 is the same as the diameter of the limiting slide rod 42, there will be no jamming when the limiting slide rod 42 and the positioning block 43 move up and down along the limiting slide groove 14, thus improving product quality and construction effect.
[0029] like Figure 4 As shown, the positioning knob 44 is an inverted cylindrical shape. The top of the inner cavity of the positioning knob 44 is integrally formed on the top of the limiting slide bar 42. The inner diameter of the positioning knob 44 is larger than the outer diameter of the limiting slide bar 42. The upper end of the positioning spring 45 is sleeved inside the positioning knob 44, and the top of the positioning spring 45 abuts against the top of the inner cavity of the positioning knob 44.
[0030] like Figure 1 and 4As shown in the figure, a buffer pressing piece 46 is integrally formed at the lower ends of both ends of the fixing clip body 41. The fixing clip body 41 and the two buffer pressing pieces 46 are in a "ji" shape. The bottom of the buffer pressing piece 46 is smooth and fits against the top of the ceiling blind plate 8. Due to the setting of the buffer pressing piece 46, when the top of the fixing clip body 41 is stressed, the lower ends of both ends can expand outward along the surface of the ceiling blind plate 8, so as to ensure that the blind plate fixing clip 4 can better press the ceiling blind plate 8 and avoid the situation of breaking the ceiling blind plate 8 at the same time.
[0031] The working principle and usage process of the utility model are as follows:
[0032] Assemble the keel main body 11 through the two-way joint 5, the three-way joint 6 and the four-way joint 7 to form a unit frame, then hoist the above unit frame on the roof through the regulator 2 and the hoisting screw rod 3, then place the ceiling blind plate 8 on the top of the blind plate overlapping pieces 12 around the unit frame, and finally press the ceiling blind plate 8 through the blind plate fixing clip 4.
[0033] Specifically, grasp the positioning knob 44 to make the two buffer pressing pieces 46 at the lower end of the fixing clip body 41 respectively straddle both sides of the keel main body 11 and be located above the blind plate overlapping piece 12. Then rotate the positioning knob 44 to make it drive the positioning block 43 to rotate through the limit slide rod 42, so that the long axis direction of the positioning block 43 is parallel to the long axis direction of the limit chute 14. Then move the blind plate fixing clip 4 downward to make the bottoms of the two buffer pressing pieces 46 abut against the top of the ceiling blind plate 8 above the blind plate overlapping piece 12. Then continue to move the blind plate fixing clip 4 downward to make the buffer pressing piece 46 at the lower end of the fixing clip body 41 press the ceiling blind plate 8, and at the same time make the positioning knob 44 overcome the elasticity of the positioning spring 45 under the limitation of the fixing clip body 41 and push the positioning block 43 downward through the limit slide rod 42 until the positioning block 43 is embedded into the internal of the limit card slot 13. Then rotate the positioning knob 44 again to make the long axis of the positioning block 43 perpendicular to the long axis of the limit chute 14. Then loosen the positioning knob 44 to make the elastic restoring force of the positioning spring 45 press the fixing clip body 41 under the limitation of the positioning block 43 and the positioning knob 44, and further press the ceiling blind plate 8 through the buffer pressing piece 46.
