The connecting rod is provided with a thread combined with the internal thread of the lower connecting component. There is a handle under the thread. The handle rotates through the threaded hole of the thread and drives The head of the umbrella-shaped connection column rotates; the upper connection assembly is located below the upper box body, and the side of the upper connection assembly is provided with a threaded hole, and a screw is provided in the threaded hole to connect with the lower box body; the middle of the bottom surface of the upper connection assembly is provided with A round hole is provided with a U-shaped groove above the round hole. the

Preferably, a plurality of threaded holes are respectively opened on the sides of the upper connection component and the lower connection component. the

Preferably, the lower connection component and the handle component are integrated, wherein the handle is curved, and the handle is welded after combining screw teeth and internal threads of the lower connection component. the

Preferably, a layer of thickened material is provided on the U-shaped groove, and the aperture diameter of the U-shaped groove is the same as the diameter of the umbrella-shaped connecting head column at the top of the handle. the

The utility model has the advantages of stable structure, easy assembly, convenient use, small size, light weight, and heavy load. The upper connection assembly and the lower connection assembly are connected through the handle connection assembly, and the screw thread on the bottom surface of the upper connection assembly only needs to be rotated. Engagement, without the installation of locks and other products, and the connecting components are tightly connected, and the box can be firmly locked. The production cost is greatly reduced, and the method is easy to implement, has strong practicability, and has a broad market prospect. the

Detailed ways

The technical solutions of the present utility model will be further specifically described below through the embodiments and in conjunction with the accompanying drawings. the

Fig. 1 is a schematic structural view of the utility model; Fig. 2 is an enlarged view of A shown in Fig. 1 . It can be seen from Fig. 1 combined with Fig. 2 that the new LED cabinet hoisting and locking device is mainly composed of LED cabinets 1, 2, upper connection assembly 4, handle connection assembly 6, lower connection assembly 3, etc., wherein the upper connection assembly 4, the lower connection assembly The side faces 41, 31 of the connection assembly 3 are respectively provided with a plurality of threaded holes 8, 7. In conjunction with Fig. 3, it can be further known that the lower connection assembly 3 is located above the lower box body 2, and the threaded hole 8 on the side surface 31 of the lower connection assembly 3 is provided with a screw to connect with the lower box body 2, and the bottom surface of the lower connection assembly 3 has a circular hole 32, which The inner surface of the circular hole 32 is provided with threads 14 . The lower connecting component 3 and the handle component 6 are integrated, and the handle 9 is welded after combining the thread 10 and the internal thread 14 of the lower connecting component 3 . the

Fig. 4 is a structural schematic diagram of the handle connection assembly of the present invention. It can be seen from Fig. 4 that the top of the handle connection assembly 6 is provided with an umbrella-shaped connection column head 5, and the middle is a connecting rod 11. The connecting rod 11 is provided with a thread 10 combined with the internal thread 14 of the lower connection assembly 3. There is a handle 9, and the handle 9 rotates on the internal thread 14 through the thread 10, and then drives the umbrella-shaped connection column head 5 to rotate. the

Fig. 5 is a structural schematic diagram of the upper connection assembly of the utility model.
