The utility model provides a blood pump which comprises a rotor assembly, a stator assembly and a shell, the rotor assembly and the stator assembly are arranged in the shell in a spaced mode in the rotation axis direction of the rotor assembly, the rotor assembly comprises an impeller, a power magnetic ring and a center shaft, and the blood pump further comprises a first magnetic bearing assembly. The first magnetic bearing assembly comprises a first inner magnetic bearing and a first outer magnetic bearing which are matched with each other, the first outer magnetic bearing is arranged on the inner wall of the shell, and the impeller, the first inner magnetic bearing and the power magnetic ring are all fixedly arranged on the center shaft; the rotor assembly can rotate around the axis of the rotor assembly so as to drive fluid to flow into and out of the shell, and in the power-on state, the rotor assembly can be spaced from the stator assembly by a first preset distance in the rotating process. All the components of the rotor assembly are fixed on the central shaft, so that the stability of relative positions of all the components is guaranteed, the overall structural strength of the rotor assembly is improved, the stability of operation of the blood pump is guaranteed, and the service life of the blood pump is prolonged.

This utility model relates to the field of pipe support devices, and more particularly to a high-strength, earthquake-resistant metal pipe support device, comprising a pipe body; earthquake-resistant components are fitted on the exterior of both ends of the pipe body, and a support component is fitted in the middle of the pipe body. This utility model utilizes an arc-shaped limiting frame in the earthquake-resistant component to adjust its height according to the diameter of the pipe body, thereby limiting and fixing the pipe body. Then, the support component is lifted and placed in the middle of the pipe body, and its rotation adjustment provides oblique support to the pipe body. Through the combined use of the rubber vibration-damping pad inside the arc-shaped limiting frame and the support column in the support component, vibration transmission can be reduced. In this way, pipe displacement, swaying, and deformation can be effectively reduced, lowering the probability of pipe rupture and leakage, protecting the substances transported inside the pipe from leakage, and preventing secondary disasters such as fires, explosions, and poisoning caused by leaks.

This utility model relates to the field of footwear and apparel technology, specifically to a cotton fiber environmentally friendly shoe upper, including a shoe upper body woven from environmentally friendly fibers and an opening integrally formed on the shoe upper body at the corresponding position of the heel of the human foot. A high-density woven layer made of environmentally friendly fibers is sewn and fixed on the shoe upper body, extending from the corresponding position of the shoe upper body at the heel of the human foot to the corresponding position of the shoe upper body at the forefoot of the human foot. The high-density woven layer is provided with a plurality of stabilizing blocks.

The application discloses a box, a battery device and a vehicle. The box comprises a bottom plate and a frame. The frame is arranged around the periphery of the bottom plate and defines a containing space. A first beam is arranged in the containing space. The first beam extends in a first direction and is connected to the frame in a second direction to divide the containing space into an electrical area and an energy area. The bottom plate comprises an energy area bottom plate and an electrical area bottom plate. The frame comprises a first frame arranged opposite in the first direction and a second frame arranged opposite in the second direction. The second frame, the electrical area bottom plate and the first beam that participate in defining the electrical area are configured as an integral piece. Thus, the force bearing interface can be expanded, the structural rigidity of the box, especially the bending and torsional rigidity, can be significantly improved, the structural rigidity and the anti-vibration fatigue performance of the box can be improved, the rigidity and the modal main frequency of the battery device can be improved, the deformation amplitude of the box structure in the vibration process can be reduced, the stress level can be reduced, and the fatigue strength can be improved.
