The utility model discloses a light-emitting diode (LED) display screen aluminum box body capable of quickly replacing internal components, which relates to the field of LED display screen aluminum box bodies, and comprises a fixed frame and a limiting baffle plate, a movable frame is arranged on the rear side of the fixed frame, and connecting components are arranged on the side surfaces of the fixed frame and the movable frame. According to the LED display screen aluminum box body with the internal components capable of being rapidly replaced, by arranging the connecting assemblies and the limiting baffles, in the using process of the LED display screen aluminum box body, workers can conveniently install the LED display screen aluminum box body, connection between the structures is tight, the situation that the LED display screen aluminum box body is accidentally opened in the subsequent using process is avoided, and the service life of the LED display screen aluminum box body is prolonged. The LED display screen aluminum box has the advantages that the LED display screen aluminum box is convenient to mount and demount, internal components can be quickly replaced, the service life of the LED display screen aluminum box is prolonged, the LED display screen can be conveniently limited, the situation that the LED display screen topples over and is damaged in the follow-up using process is avoided, and the LED display screen aluminum box is convenient to use by workers.

The utility model relates to the technical field of video equipment, in particular to multifunctional video equipment which comprises a display screen and a supporting assembly arranged below the display screen, the supporting assembly comprises a supporting frame, sliding rails are symmetrically and fixedly installed on the inner side surface of the supporting frame, an adjusting assembly is arranged between the two sliding rails, and a protection assembly is arranged on one side of the supporting frame. The protection assembly comprises a plurality of L-shaped rotating rods symmetrically and fixedly installed on the surfaces of the two sides of the supporting frame, rotating plates are rotationally connected to the outer sides of the L-shaped rotating rods, and a plurality of hinged protection plates are fixedly connected to one ends of the two rotating plates on the same side. According to the utility model, the height of the display screen is quickly reduced by moving the display screen downwards along the support frame, and then the display screen is shielded from the front of the display screen and protected by overturning the plurality of protection plates, and meanwhile, the gravity center of the display screen is reduced, so that the whole video equipment is more stable, and the video equipment is prevented from being toppled and damaged due to mistaken touch; and the protection effect of the video equipment is improved.

The utility model relates to the technical field of logistics storage, and disclose a movable goods shelf anti -toppling locking mechanism, including goods shelf body, the surface of goods shelf body is connected with a plurality of placing plate slidingly, the surface of goods shelf body is equipped with support device, support device includes two round bars, two round bars all are fixedly connected with the surface of goods shelf body, the circular arc surface fixed connection of round bar has two fixed blocks, the fixed block is slidably inserted with sliding rod, one end of sliding rod is fixedly connected with the supporting plate, the surface of fixed block is fixedly connected with fixed link, the circular arc surface slidingly connected with operating plate of fixed link, the surface of operating plate is fixedly connected with the plug rod. This movable goods shelf anti -toppling locking mechanism avoids the goods shelf to fall in the process of moving because of uneven ground, load eccentricity and the like, not only can prevent the valuable article from damaging because of falling, can prevent the article from smashing to the operator simultaneously, thereby causes the situation of the operator to be wounded to appear.

The utility model discloses a polishing machine arm with high stability, which relates to the field of polishing machine arms and comprises a mechanical arm, a fixing block and a polisher, a fixing seat is arranged below the mechanical arm, and a mounting component is arranged between the mechanical arm and the fixing seat. And the mounting assembly comprises a connecting block, a limiting ring, a positioning block, a limiting piece, a clamping block, a reinforcing cover and a square block. According to the high-stability polishing machine arm, by arranging the mounting assembly and the limiting assembly, in the using process of the polishing machine arm, the overall connection of the polishing machine arm structure is improved, so that the polishing machine arm has high stability, and the situation that the polishing machine arm topples over and is damaged in the subsequent using process is avoided; and meanwhile, certain detachability is achieved, a worker can conveniently replace and maintain a polishing structure of the polishing machine arm, efficient operation of the polishing machine arm is guaranteed, and the worker can conveniently use the polishing machine arm.
