The application belongs to the technical field of strength test of single lug joint of vertical tail wall plate root of an airplane, and particularly relates to a radial compression test loading structure of a single lug joint shaft hole of a vertical tail wall plate root of an airplane, when strength test is performed by using the radial compression test loading structure, a test machine can apply a pressure load on a wall surface of a loading pressure platform, the pressure load can be transmitted to a shaft hole of a single lug joint of a single lug joint test piece through a support bushing and a loading shaft, a radial compression load is applied in the shaft hole of the single lug joint, in the process, two support bushings can support the single lug joint of the single lug joint test piece from two sides, two support plates can support a transition section of the single lug joint test piece from two sides, lateral deviation of the single lug joint test piece is prevented, and the two support bushings and the support plates can follow the loading pressure platform to follow the support, the stress environment of the single lug joint can be well ensured, and the accuracy of a test result can be ensured.

The utility model discloses a cage loading and unloading device and an unmanned vehicle. The cage loading and unloading device comprises a translation mechanism and a lifting mechanism, the translation mechanism comprises a translation guide rail and a translation sliding table arranged on the translation guide rail, and the translation sliding table can slide back and forth along the translation guide rail; the lifting mechanism is arranged on the translation sliding table and comprises a lifting guide rail, a lifting sliding table, fork teeth and lateral baffles, the lifting guide rail is fixedly installed on the translation sliding table in the vertical direction, the lifting sliding table is installed on the lifting guide rail in a sliding mode, the fork teeth are fixedly connected with the lifting sliding table, and the lateral baffles are fixedly connected to the two sides of the lifting sliding table. According to the cage loading and unloading device and the unmanned vehicle, through lifting operation of the lifting table, vertical movement of the cage can be achieved, the cage can be matched with the translation mechanism to complete horizontal movement, the cage does not need to be overturned, and therefore potential safety hazards and package damage in the overturning process are avoided.

This utility model discloses a production device for anti-deformation frame of a freezer door, relating to the field of anti-deformation frame manufacturing technology for freezer doors. It includes a frame and a support mechanism. The support mechanism comprises two sets of support plates, which are movably mounted on the top of the frame. Movable blocks are movably mounted on the support plates. A limiting platform is provided at one end of the movable block near the outer side of the frame. A fixing block is fixedly mounted at the rear end of the support plate. A transverse driving mechanism is provided below the support mechanism, and a mounting platform is provided on the transverse driving mechanism. Drilling mechanisms are provided at both ends of the mounting platform. This utility model design, through the limiting platform on the side of the movable block, allows the frame to be clamped and fixed by the movable block and the fixing block. The limiting platform abuts against the inner wall of the frame, thereby limiting the left and right sides of the frame and preventing lateral displacement during processing, which helps improve the processing accuracy of the frame.

This utility model discloses an injection mold with a guiding demolding structure, including a fixed mold and a moving mold. Two guide rods are fixedly installed on both outer walls of the fixed mold via support plates. Connecting plates are fixedly installed on both outer walls of the moving mold. Guide sleeves that mate with the two guide rods on the same side are fixedly installed on the upper surfaces of the two connecting plates through installation openings. Sliding rods are fixedly installed on both outer walls of the fixed mold via buffer frames. Moving plates are slidably installed on the outer walls of the two sliding rods. This utility model, by setting up components such as guide rods, guide sleeves, buffer springs, and buffer plates, and the precise cooperation between the guide rods and guide sleeves, controls the movement error of the moving mold to a very small range, effectively avoiding lateral displacement when the moving mold separates from the fixed mold. This significantly reduces problems such as flash and dimensional deviations in the product. At the same time, the buffer springs and buffer plates absorb impact forces during mold opening and closing, avoiding damage to the mold caused by rigid collisions and extending the mold's service life.
