This utility model discloses a transport box for laboratory mice with an anti-collision and buffer structure, including an outer anti-collision box and an inner placement box. The placement box holds the laboratory mice, and the outer wall of the placement box is provided with multiple buffer blocks, which are placed between the outer anti-collision box and the placement box. Both the outer anti-collision box and the top of the placement box are provided with door opening and closing components. The top and bottom of the placement box are provided with upper and lower buffer components, and the opposite side wall is provided with side buffer components. The upper and lower buffer components and the side buffer components are all set in conjunction with the buffer blocks. This utility model provides basic anti-collision protection through the outer anti-collision box, and with the buffer blocks on the outer wall of the placement box, it can initially mitigate the impact of external collisions. The upper and lower buffer components and the side buffer components work together to effectively absorb the vertical and lateral vibrations and bumps during transportation, reducing the stress response or physical injury to the laboratory mice caused by collisions and bumps.

The utility model discloses a packaging barrel with a buffering protection function. The packaging barrel comprises an outer-layer protection frame, a plastic inner container, a top buffering assembly, a lateral buffering layer and a bottom damping mechanism. The outer-layer protective frame is of a metal grid structure, and the plastic inner container is arranged in the outer-layer protective frame. The top buffering assembly is composed of a plurality of elastic arch-shaped supporting plates, the arch-shaped supporting plates are formed by welding rectangular pipes, and the tops of the arch-shaped supporting plates are provided with arc-shaped aluminum plates for connection. The lateral buffer layer is composed of two layers of foam material plates, and a corrugated structure is arranged between the two layers of foam material plates and embedded in the inner side of the metal grid structure. The bottom shock absorption mechanism comprises composite structure shock absorption supports arranged at the four corners and deformable rib plates arranged in a radial shape and is used for enhancing the shock resistance and energy absorption capacity. The container barrel is reasonable in structure, the impact resistance of the container barrel in the transportation and carrying process is effectively improved, the inner container is prevented from being damaged or leaking, and transportation safety is guaranteed.

This invention relates to the field of switchgear and discloses an outdoor fully enclosed insulated ring network switchgear, comprising a base, an opening and closing mechanism at the top of the base, an inlet mechanism inside the opening and closing mechanism, a shielding canopy fixedly connected to the top of the opening and closing mechanism, and a cleaning mechanism outside the opening and closing mechanism. The opening and closing mechanism includes multiple fixed brackets, the bottom ends of which are fixedly connected to the top of the base. Two of the fixed brackets are internally slidably connected to sliding rods, and each sliding rod is externally fixedly connected to a fixed rod. This invention allows for convenient opening and closing of the switchgear, enabling operators to inspect and maintain the equipment from three directions without disassembling the cabinet as in traditional methods, significantly reducing maintenance difficulty and workload. When the switchgear is closed, the protective shell compresses the sealing gasket to form a tight seal, effectively preventing dust and moisture from entering.

The utility model relates to the technical field of shock absorption, and discloses a buffer type spring washer which comprises a shell, four sliding columns are fixedly connected to the interior of the shell, four limiting columns are fixedly connected to the interior of the shell, springs are arranged on the outer walls of the four limiting columns in a sleeved mode, two heat insulation layers are arranged in the shell, and the two heat insulation layers are arranged in the shell. The sides, close to each other, of the two heat insulation layers are fixedly connected with rubber layers, and the outer wall of the shell is fixedly connected with a telescopic assembly. When external force acts on the shell, the shell can generate inward extrusion deformation due to the material characteristics of the shell, in the process, the outer walls of the sliding columns relatively slide along the inner walls of the limiting columns, pressure is applied to the internal springs at the same time, the springs are forced to deform, elastic potential energy is stored, and the elastic potential energy is stored along with disappearance of the external force. The elastic potential energy accumulated by the spring is released instantly, and the shell is pushed to recover to the initial state quickly by the strong elastic force.

The utility model discloses a spring piece mobile phone antenna, which comprises a mobile phone antenna body, three spring pieces are arranged on the back of the mobile phone antenna body, the three spring pieces are respectively arranged at the front end, the middle end and the rear end of the mobile phone antenna body, and two conductive contact pieces are fixedly arranged above the middle part of the mobile phone antenna body. According to the mobile phone antenna, when the metal elastic piece deforms, the arched protruding part of the metal elastic piece can sink inwards after resisting a part of external force, and the sunken metal elastic piece abuts against the spiral spring. The compressed spiral spring has a certain elastic resilience force, so that the external force is partially counteracted through the compression resilience force of the spiral spring, the mobile phone antenna can be better buffered and protected, the impact effect of external force is reduced, the external force is prevented from directly acting on the mobile phone antenna, and the service life of the mobile phone antenna is prolonged.
