This utility model discloses an aluminum shell structure for an electrolytic capacitor, including a capacitor core package. A shell is provided at the outer end of the core package, and a support strip is provided inside the shell. Multiple sets of support strips are arranged around the shell. A cover is provided on top of the shell, and the cover cooperates with the shell. A pressure-relief column is provided inside the cover. A protective strip is provided inside the support strip, and a protective pad is provided inside the pressure-relief column. A partition cavity is opened inside the shell, and a vent hole is opened inside the shell. A pressure relief pipe is provided at the outer end of the shell, and a movable piston is provided inside the pressure relief pipe. A pressure-applying spring is provided between the movable piston and the wall of the pressure relief pipe. A pressure relief hole is opened at one end of the pressure relief pipe. This aluminum shell structure provides better shock resistance, suppresses explosions, stabilizes rise, and improves protection capabilities.

The utility model discloses an air pressure valve seat which comprises a valve seat body, a cleaning mechanism is installed in the valve seat body, the cleaning mechanism comprises an elastic supporting assembly, the elastic supporting assembly is installed in the valve seat body, an extrusion ring is installed on the top of the elastic supporting assembly, and a guide piece is installed on the side, close to the sealing face of the valve seat body, of the extrusion ring. Adsorption cotton used for cleaning the sealing face of the valve seat body is installed on the guide piece, and a push block used for pushing the extrusion ring is installed at the bottom of the valve element body. Compared with the prior art, the air pressure valve seat has the advantages that solid particles on the sealing surface of the valve seat can be removed in the closing process of the valve core, and the solid particles are prevented from hindering or interfering the tight contact between the sealing surface of the valve seat and the surface of the valve core as far as possible, so that the sealing effect of the valve is improved, and the normal work of equipment is ensured; meanwhile, abrasion and corrosion of solid particles to the sealing surface of the valve seat are reduced to a certain extent, the frequency of maintaining or replacing the valve seat by a user is reduced, and the maintenance cost is effectively reduced.

This utility model discloses a high-voltage testing device for surge arresters. The device includes a testing instrument, an adsorption conductive module, and an insulating rod. The adsorption conductive module is detachably mounted on the top of the insulating rod, and the end of the monitoring harness furthest from the testing instrument is detachably connected to the adsorption conductive module. In this embodiment, the adsorption conductive module can be moved to the device under test and adsorbed via the insulating rod, enabling remote operation, ensuring operator safety, eliminating the need for an aerial work platform, saving costs and time, and improving efficiency. The detachable nature of the adsorption conductive module and the insulating rod facilitates storage and transport. The detachable nature of the monitoring harness and the adsorption conductive module facilitates harness replacement and maintenance. The overall structure can stably establish an electrical connection between the adsorption conductive module and the device under test, ensuring smooth testing.

The invention discloses a clavicle fracture intramedullary fixing nail and a clavicle fracture intramedullary fixing system.The clavicle fracture intramedullary fixing nail can be implanted into a clavicle through an external bone drill and comprises a head section and a tail section, and the head section comprises a thread structure extending from the edge of the first end of a nail body of the clavicle fracture intramedullary fixing nail to the center; the tail section comprises a thread structure extending from the edge of the second end of the nail body of the intramedullary fixing nail for clavicle fracture to the center, the head section and the tail section have the same rotation direction of the thread structure, and the thread pitch of the head section is larger than that of the tail section. The end portions of the head section and the tail section are clamped through a bone drill, and the head section and the tail section are meshed with cortical bones at the edges of the two ends of the clavicle through a thread structure. The intramedullary fixation system for the clavicle fracture comprises an incision construction unit, a clavicle reduction and fixation unit, a patient clavicle imaging unit and an incision suture unit. The variable-pitch thread structures at the two ends of the intramedullary fixing nail for the clavicle fracture are meshed with cortical bones to achieve the pressurization effect, meanwhile, loosening after meshing is avoided, and the fracture clavicle can be firmly maintained to be reset.

The molten aluminum placing device comprises two L-shaped frames which are arranged in a spaced mode, the lower portions of the vertical sections of the two L-shaped frames are connected through a transverse rod, vertical rods are integrally welded to the upper portions of the free ends of the horizontal sections of the two L-shaped frames, and an upper hinge seat and a lower hinge seat are integrally arranged on the inner sides of the vertical rods. A placing assembly is arranged between the two L-shaped frames, the upper hinge seat is hinged to the outer wall of the placing assembly through a first connecting rod inclining downwards, the lower hinge seat is hinged to the outer wall of the placing assembly through a second connecting rod inclining downwards, and electric-hydraulic push rods are hinged to the horizontal sections of the L-shaped frames. The free end of the electric-hydraulic push rod is hinged to the middle of the second connecting rod, through control of the electric-hydraulic push rod, the placing assembly can be turned over, so that molten aluminum in a molten aluminum barrel or an aluminum ingot smelting furnace is poured out, close-range contact between people and the smelting furnace is avoided, the use safety and reliability of the device are improved, and the device is suitable for industrial production and has good application prospects. And the practicability is very high.
