[0023] Reference Figures 1 to 3 A universal counterweight block for testing a roof luggage rack comprises a counterweight base plate 1, a counterweight layer plate 2 and a lifting ring. The counterweight base plate 1 is used to connect with the luggage rack and support the bottom. The counterweight layer plate 2 is superimposed on the counterweight base plate 1. The counterweight layer plate 2 is provided with a plurality of different weights. A lifting ring (not shown) is provided on the counterweight base plate 1 for lifting and moving the counterweight base plate 1 and the counterweight layer plate 2. The counterweight layer plate 2 and the counterweight base plate 1 are both provided with installation guides (not shown) so that the counterweight layer plate 2 can be positioned and installed more accurately when being superimposed and installed.

[0024] The counterweight base plate 1 is provided with a plurality of fixing holes 11 and mounting holes 12. The fixing holes 11 are symmetrically arranged on both sides of the counterweight base plate 1. The fixing holes 11 are used to connect with the luggage rack, and the mounting holes 12 are used to install lifting rings. The lifting rings are arranged on the mounting holes 12 at the four corners of the counterweight base plate 1.

[0025] The counterweight base plate 1 and the counterweight layer plate 2 are both provided with a plurality of counterweight connection holes 3. The counterweight connection holes 3 on the counterweight base plate 1 are arranged in the middle part of the counterweight base plate 1. The counterweight connection holes 3 on the counterweight base plate 1 are adapted to the counterweight connection holes 3 of the counterweight layer plate 2 installed thereon. When there are multiple counterweight layers 2, the counterweight connection holes 3 on the counterweight layer plates 2 between the upper and lower layers are adapted to each other, that is, they can be connected to each other, preferably by bolts.

[0026] The following will refer to Figures 1 to 3 , the working principle of the utility model is explained.

[0027] The counterweight base plate 1 is connected to the luggage rack by bolts through the fixing holes 11. The counterweight layer plates 2 are selected according to the weight requirements of the standard and are stacked on the counterweight base plate 1 in sequence. The counterweight base plate 1 and the counterweight layer plates 2 are connected and fixed to each other by bolts passing through the counterweight connecting holes 3. The lifting ring is tightened to the mounting hole 12 of the counterweight base plate 1 to facilitate lifting using an overhead crane. The counterweight base plate 1 and the counterweight layer plates 2 can be combined into a variety of different weights to meet different luggage rack test requirements. Since the counterweight base plate 1 and the counterweight layer plates 2 are made of hard materials such as steel plates, the products have high strength and can be reused, which greatly reduces the test cost and ensures the test efficiency.

[0028] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
