This utility model relates to the field of film roll processing technology, specifically a film roll support assembly. The utility model includes a support shaft that can be axially inserted through the inner cavity of the film roll and two support plates arranged parallel to each other and vertically. The two support plates are spaced apart, and their top sides respectively support one end of the support shaft, allowing the film roll to be suspended in the air. The same side of both support plates is inclined and together forms a guide ramp that allows the support shaft to move to the top side of the support plates. Both ends of the support shaft are coaxially fitted with rotating parts for gripping. This utility model effectively supports the inner cavity of the film roll's paper tube and allows for easy separation of the film roll from the ground, preventing deformation of the part of the film roll in contact with the ground during long-term storage.

The application belongs to the technical field of sensor layout optimization, and discloses a power transmission tower sensor optimal arrangement method based on a marine predator algorithm, which comprises the following steps: determining the modal order number that needs to be considered in the power transmission tower sensor optimal arrangement by using a Fisher information matrix 2 norm change rate; determining the number of sensors that need to be arranged on the power transmission tower by using a maximum value of non-diagonal elements of a modal confidence criterion matrix; and taking the modal confidence criterion matrix as a fitness function of the marine predator algorithm, and determining the arrangement position of the sensor on the power transmission tower by using a marine predator intelligent optimization algorithm. The application determines the optimal arrangement position of the sensor on the power transmission tower by using the marine predator intelligent optimization algorithm starting from the modal analysis of the power transmission tower, which has important practical value for determining the monitoring state of the power transmission tower by monitoring data of the sensor.

This utility model discloses a novel EOL (Electronic Voltage Attached) storage rack auxiliary testing fixture, relating to the field of high-voltage test box technology. It includes an aluminum profile body, a high-voltage connector mounting position, a low-voltage test interface box, an outer railing, and a cabinet door. The cabinet door is located on the front side of the aluminum profile body. Above the cabinet door, a railing for suspending wire harnesses is mounted on the aluminum profile body via support rods. The low-voltage test interface box is also located above the aluminum profile body, and a high-voltage connector mounting position is located on one side of the low-voltage test interface box. This utility model features a reasonable structural design, convenient storage, and easy operation, reducing the burden on operators and demonstrating strong practicality.

This invention relates to the field of office desk technology, specifically to a folding office desk that is easy to store; it includes two flat panels connected by a support mechanism. Each of the two flat panels has a symmetrical support leg on its lower front and rear sides away from the support mechanism, and the support legs are hinged to the flat panels. A storage mechanism is located below both flat panels, and the support mechanism cooperates with the storage mechanism. A fixing mechanism is located on the side of the two flat panels away from each other to secure the two flat panels after folding. This invention solves the main problems of existing folding office desks, such as instability after folding and the lack of storage space for placing items.

The utility model provides a combined type composite storage rack which comprises a group of hinged storage plates, each storage plate is provided with a storage assembly used for storing sampling containers with different diameters, and the storage plates are jointly provided with a connecting assembly. The connecting assembly comprises a pulling and holding structure and a connecting structure, wherein the pulling and holding structure is arranged on one set of storage plates and used for connecting the storage plates after the storage plates are unfolded, and the connecting structure is arranged on two of the storage plates and used for stabilizing the storage plates after the storage plates are folded. According to the invention, through the cooperation of the arranged object placing plate and the placing assembly, sampling containers with different diameters can be stabilized on the object placing plate, the convenience in use is further improved, through the arranged connecting assembly, the object placing plate can be folded and unfolded, and when the number of the sampling containers is large, the placing position can be increased by unfolding the object placing plate; when the number of the containers is small, the storage plate is folded to save space, and the placement positions of the sampling containers can be flexibly adjusted.
