Detailed Implementation

[0016] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Please see Figures 1-3 This utility model provides a technical solution:

[0018] A bracket for fixing a lamp to an I-beam includes a quick-release structure 101 and a connecting strip 201 (in this embodiment, the connecting strip 201 is a chain) installed on the quick-release structure 101. The lamp 301 is installed at the free end of the connecting strip 201. The quick-release structure 101 is used for quick assembly and disassembly of the connecting strip 201 and the I-beam 401.

[0019] Preferred, refer to Figure 2 or Figure 3In this embodiment, the quick-release structure 101 includes a top rod 1011, a connecting sleeve 1012 hinged to the middle of the top rod 1011, and a first clamping claw and a second clamping claw respectively hinged to both ends of the connecting sleeve 1012. When fixed, the top end of the top rod 1011 abuts against the I-beam 401, at which time the first clamping claw and the second clamping claw can achieve linkage clamping or linkage release.

[0020] Specifically, from Figure 2 From the perspective of this embodiment, the first gripper includes a screw 1013 with its bottom end hinged to the left end of the connecting sleeve 1012, a first sliding sleeve 1014 slidably sleeved on the screw 1013, a first pressure plate 1015 fixedly installed on the first sliding sleeve 1014, and an adjusting nut 1016 threadedly connected to the screw 1013, with the first sliding sleeve 1014 located between the connecting sleeve 1012 and the adjusting nut 1016; the second gripper includes a connecting rod 1017 with its bottom end hinged to the right end of the connecting sleeve 1012, a second sliding sleeve 1018 slidably sleeved on the connecting rod 1017, a second pressure plate 1019 fixedly installed on the second sliding sleeve 1018, and a limiting ring 10110 fixedly installed at the top end of the connecting rod 1017, with the second sliding sleeve 1018 located between the connecting sleeve 1012 and the limiting ring 10110.

[0021] To facilitate the quick-release structure 101's adaptation to I-beams 401 of different sizes within a certain size range, in this embodiment, threaded holes (not marked in the figure) are provided at both ends of the connecting sleeve 1012. The central axes of the two threaded holes are collinear with the central axis of the connecting sleeve 1012. An adjusting rod 501 is threaded into either threaded hole. The free ends of the two adjusting rods 501 are hinged to the bottom end of the screw 1013 and the bottom end of the connecting rod 1017, respectively. When adapting to I-beams 401 of different sizes, the two adjusting rods 501 can be screwed on separately to adjust the extension length of the adjusting rods 501 extending from both ends of the connecting sleeve 1012, thus achieving the purpose of adapting to I-beams 401 of different sizes within a certain size range.

[0022] During installation, in order to increase the contact area between the top of the top rod 1011 and the I-beam 401 and further increase the stability of the connection, a top plate 601 is also installed on the top of the top rod 1011 in this embodiment.

[0023] Working principle:

[0024] from Figure 2From the perspective of installation, first adjust the extension length of the two adjusting rods 501 according to the horizontal width of the I-beam 401, and then make the top plate 601 abut against the bottom surface of the I-beam 401. Then rotate the first sliding sleeve 1014 and the second sliding sleeve 1018 respectively, so that the first pressure plate 1015 and the second pressure plate 1019 can press on the I-beam 401. Then tighten the adjusting nut 1016, so that the adjusting nut 1016 moves downward in the vertical direction. After the adjusting nut 1016 abuts against the first sliding sleeve 1014, continue to tighten it. During this process, the first sliding sleeve 1014 and the first pressure plate 1015 move downward synchronously. After the first pressure plate 1015 abuts against the I-beam 401, if the second pressure plate 1019 is not yet pressed firmly onto the I-beam 401, continue to tighten the adjusting nut 1016. During this process, the connecting sleeve 1012 rotates clockwise until both the first pressure plate 1015 and the second pressure plate 1019 are pressed firmly onto the I-beam 401, thus completing the quick installation of the lamp 301. For disassembly, simply reverse the direction of the adjusting bolt.

[0025] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
