Detailed ways

The present utility model will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

Example 1

As shown in Figure 1-2, this embodiment provides a fixing device for lighting fixtures under I-beams, including: fixture fixing part 4, left fixing part 1 and right fixing part 2, left fixing part 1 and right fixing part 2 The bottom is connected to the lamp fixing part 4 through the vertical screw rod 3. The position of the lamp fixing part 4 on the vertical screw rod 3 is adjustable, so that the height of the lamp 6 installed on the lamp fixing part 4 is adjustable.

Specifically, the left fixing member 1 includes: a left bayonet portion 11, a left vertical portion 12 and a left horizontal portion 13. The left bayonet portion is in the shape of "匚" and is used to engage the left end of the lower wing plate of the I-beam 5. The left vertical part 12 is connected to the bottom end of the left bayonet part 11 , extends downward from the bottom of the left bayonet part 11 , and is connected to the left horizontal part 13 . The right fixing piece 2 includes: a right bayonet portion 21, a right vertical portion 22 and a right horizontal portion 23. The right bayonet portion 21 is symmetrically arranged with the left bayonet portion 11 and is used to engage the right end of the lower wing plate of the I-beam 5; The right vertical part and the left vertical part are connected by bolts. After the left bayonet part 11 and the right bayonet part 21 clamp the lower wing plate of the I-beam 5, bolts of appropriate length are selected according to the actual situation for connection, so as to suitably With different sizes of I-beam 5.

The right horizontal part 23 overlaps the left horizontal part 13 in a completely overlapping state (when the left vertical part 12 and the right vertical part 22 are completely fitted, that is, when adapting to the smallest size I-beam) or in a partially overlapping state (when the left vertical part 12 and the right vertical part 22 are completely fitted) There is a gap between the straight part 12 and the right vertical part 22 (that is, when adapting to a slightly larger size I-beam), either one of the right horizontal part 23 and the left horizontal part 13 is provided with a waist-shaped hole 24. This In the embodiment, a waist-shaped hole 24 is provided in the right horizontal part 23, and a round hole is provided in the left horizontal part 13. The round hole and the waist-shaped hole 24 should ensure overlap, and the vertical screw 3 passes through the round hole and the waist-shaped hole 24. The back extends downward, and the connection is fixed by two upper and lower nuts, which further ensures the tightness of the left fixing part 1 and the right fixing part 2 and ensures the stability of the structure.

As shown in Figure 3, the lamp fixture 4 is in a "┐" shape as a whole, and its top horizontal section and the bottom of the vertical screw 3 are fixed by two nuts. Adjust the position of the two nuts on the vertical screw 3. The height of the lamp fixing part 4 is adjusted, thereby adjusting the height of the lamp 6. The vertical section of the lamp fixture 4 is provided with a fixing hole 41 at the bottom and a threading hole 42 in the middle. The fixing bolt 43 passes through the fixing hole 41 and is connected to the hinge 61 of the lamp 6, thereby fixing the lamp 6 to the lamp fixture 4. superior. The wires 62 on the lamp 6 pass through the threading holes 42 and then extend upward. The wires 62 are guided and fixed through the threading holes 42 .

Specifically, the installation process of this fixture is as follows:

First, the left fixing part 1 and the right fixing part 2 are respectively clamped on both ends of the lower wing plate of the I-beam 5, and then the left vertical part 12 and the right vertical part 22 are connected through bolts. Fixing piece 2 performs preliminary fixation.

Then pass the top of the vertical screw 3 through the waist-shaped hole 24 and the round hole in the overlapping portion of the right horizontal part 23 and the left horizontal part 13, and fix the vertical screw 3 with a nut.

Then install the lamp fixture 4 on the lower section of the vertical screw 3, adjust the angle and tighten the nut.

Finally, the fixing bolts 43 are passed through the fixing holes 41 in the lower part of the lamp fixing part 4 and then connected to the hinge 61 of the lamp 6. At this time, the fixed installation of the lamp 6 has been completed. Then pass the wire 62 through the wire hole 42, fix it, and extend it upward to connect with the power wire on the top.

Example 2

On the basis of Embodiment 1, since the wire 62 actually has multiple leads inside, and in order to facilitate connection with the power line, part of the leads needs to be exposed. Therefore, it is inconvenient to pass through the threading hole 42. Therefore, in this embodiment, Example. As shown in Figure 4-6, the fixing hole 41 is shaped like an arrow. The bottom of the fixing hole 41 is a notch. The wire 62 can be inserted into the fixing hole 41 from the bottom notch. After being inserted, a fixing bolt is used. 43 and fixing holes 41 to improve the convenience of installation.
