[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-4 , the utility model provides a technical solution:

[0020] In the present technical solution, a ceiling bridge that is easy to install comprises two symmetrically arranged bridge side panels 1, a plurality of cross arms 2 are arranged between the bottoms of the two bridge side panels 1, and two adjacent cross arms 2 are evenly spaced. The upper end of the bridge side panel 1 is equipped with a connecting plate 5, and the side of the connecting plate 5 away from the bridge side panel 1 is equipped with a reinforcing rib 4. The bridge side panel 1 is equipped with an L-shaped bracket 3, and the side wall of the L-shaped bracket 3 is fitted with the side wall of the bridge side panel 1. The bridge side panel 3 is fitted with the L-shaped bracket 3. The L-shaped bracket 3 is equipped with a fastener 6, and an adjustment slide 7 is provided at the joint between the L-shaped bracket 3 and the bridge side plate 1. The fastener 6 includes a fastening screw 24 and an anti-slip screw 10. The fastening screw 24 is arranged in the adjustment slide 7. The outside of the fastening screw 24 is screwed with a fastening nut 22. The fastening nut 22 is arranged on the outside of the L-shaped bracket 3. The bottom end of the fastening screw 24 is provided with an anti-slip groove 23. The anti-slip screw 10 is screwed in the anti-slip groove 23. The top of the L-shaped bracket 3 is equidistantly provided with mounting holes 8.

[0021] In this technical solution, two more ladder crossbeams are added to the top of the ladder frame through the original ladder-type bridge frame, so that the bridge frame is stable and not easy to deform. The top of the L-shaped bracket 3 is installed on the roof, and the side end is connected to the bridge frame side plate 1. Through the cooperation of the fastener 4, it can also adjust the distance from the roof. The fastening screw 24 and the fastening nut 22 cooperate to realize the bolt in the prior art, and an anti-slip groove 23 is provided at the bottom end of the fastening screw 24, and the anti-slip screw 10 is screwed in. The three limiting columns 17 installed on the anti-slip cylinder 9 outside the anti-slip screw 10 support the fastening nut 22, thereby circumferentially limiting the fastening nut 22, and the spiral groove 18 on the limiting column 17 engages with the fastening screw 24, thereby limiting the anti-slip cylinder 9 and the anti-slip screw 10.

[0022] In some technical solutions, the inner wall of the anti-slip cylinder 9 is provided with a reverse internal thread 19, and the outer part of the anti-slip screw 10 is provided with a reverse external thread 20 at the joint with the anti-slip cylinder 9, and the reverse internal thread 19 and the reverse external thread 20 match each other.

[0023] In this technical solution, the external thread of the anti-slip screw 10 is divided into two parts. The front part cooperates with the internal thread of the anti-slip screw groove 23, and the rear part cooperates with the reverse internal thread 19 of the anti-slip cylinder 9, thereby installing the anti-slip cylinder 9 on the outside of the anti-slip screw 10.

[0024] In some technical solutions, a rotary disk 21 is installed at the end of the anti-slip screw 10, and a cross groove is opened on the outer wall of the rotary disk 21.

[0025] In this technical solution, the anti-slip screw 10 is easily rotated by the turntable 21, and the cross groove 5 is provided to facilitate operation with a screwdriver.

[0026] In some technical solutions, an annular rotation groove 11 is formed on the outer wall of the fastening nut 22 , and the end of the limiting column 17 is arranged in the annular rotation groove 11 .

[0027] In this technical solution, when the anti-slip screw 10 is screwed into the anti-slip groove 23, the anti-slip cylinder 9 will rotate accordingly, and when the limiting column 17 contacts the fastening nut 22, it can rotate in the annular groove 11 until it contacts the inner wall of the annular groove 11, thereby supporting the fastening nut 22 and performing circumferential limiting.

[0028] In some technical solutions, a fixing ring 12 is fixedly mounted on the outer upper end of the fastening screw 24 , and an annular pressing plate 14 , a spring 16 and an annular rubber sheet 15 are sheathed on the circumferential surface of the fastening screw 24 .

[0029] In this technical solution, when the fastening screw 24 is rotated, the annular rubber sheet 15 slides upward due to the action of the screw hole. As the screw is further twisted, the annular rubber sheet 15 contacts the fixing ring 12. The annular rubber sheet 15 is deformed due to the action of the fixing ring 12, sealing the screw hole. The spring 16 is located on the upper side of the annular pressure sheet 14, so that the annular pressure sheet 14 is squeezed downward due to the action of the spring 16. The extrusion block 13 is squeezed downward due to the action of the annular pressure sheet 14, so that the extrusion block 13 further squeezes the edge of the annular rubber sheet 15, thereby improving the sealing effect. The annular pressure sheet 14 is located on the upper side of the fixing ring 12, the spring 16 is located on the upper side of the annular pressure sheet 14, the annular rubber sheet 15 is located on the lower side of the fixing ring 12, and the extrusion block 13 is fixedly installed at the lower end edge of the annular pressure sheet 14.

[0030] Working principle: When in use, make the top edge of the L-shaped bracket 3 contact with the roof and install it to the roof through the mounting hole 8. Then, move the bridge side plate 1 up and down at the side edge of the L-shaped bracket plate 3 to adjust it to a suitable height position with the roof. After adjustment, turn the fastening nut 22 to make it fit tightly with the side wall of the L-shaped bracket 3, thereby fixing the L-shaped bracket 3 to the bridge side plate 1. Finally, install the anti-slip cylinder 9 on the anti-slip screw 10, and then screw the anti-slip screw 10 into the anti-slip groove 23. While screwing in, the spiral groove 18 on the limit column 17 will engage with the external thread of the fastening screw 24 until the end of the limit column 17 is placed in the annular groove 11 on the fastening nut 22, and the fastening nut 22 is limited.
