The invention discloses a rammer release device of a dynamic compactor. The rammer release device of the dynamic compactor comprises a lifting frame and a lifting hook. A lifting block is installed inside the lifting frame. The lifting hook comprises a hook handle section at the upper portion and a hook holding section formed by notching the lower portion of the lifting hook. A connecting frame is hinged to the lower end of the lifting frame. The lower end of the connecting frame is hinged to the middle of the lifting hook. A rammer release device is hinged to the middle of the connecting frame and comprises a rammer release steel wire rope and a transverse frame extending out of the connecting frame. One end of the transverse frame is hinged to the middle of the connecting frame. The other end of the transverse frame is fixedly connected with the head end of the rammer release steel wire rope. The tail end of the rammer release steel wire rope winds around the upper end of the lifting frame. A stop shaft is installed at the position, corresponding to the hook handle section, of the middle of the transverse frame. The transverse frame is hinged to the connecting frame through a hinge pin. Compared with a traditional rammer release device of the dynamic compactor, the rammer release device of the dynamic compactor has the advantages that the structure is simple, the opening degree is large, a rammer can be hooked conveniently, and working efficiency of workers is improved. According to the rammer release device of the dynamic compactor, the lifting frame and the lifting hook are connected through the connecting frame, so that the free height of the rammer release device is decreased effectively, and rammer release reliability is improved.

The invention is concerned with storage battery fortified by glass fiber reinforced resin and production. Each single battery connects with others by conductive connecting piece and they are reinforced by resin composites. The resin composite contains reinforced material being one or some of glass fiber, carbon fiber, aramid fiber or PVA fibers with super-large molecular weight. The resin material for reinforcing is thermoset resin containing epoxy resin, unsaturated polyester resin, phenolic resin or vinyl ester resin. Wind each battery with fiber and cover the top of battery with module, pour with thermoset resin and heat to solidify and connect each single battery with conductive connecting piece. The battery has better capability to bear vibration, speedup and impaction to solve a problem for security and low cost to battery.

The embodiment of the invention provides a resistivity Logging tooL. The resistivity Logging tooL comprises a driLL coLLar and a resistivity Logging exciting device which is instaLLed on the driLL coLLar; the resistivity Logging exciting device comprises an exciting coiL and a cover assembLy which is arranged on the outer cyLindricaL surface of the driLLer coLLar, the cover assembLy and the outercyLindricaL surface of the driLL coLLar form a chamber, the exciting coiL is arranged in the chamber, and an insuLating seaLant is arranged in the chamber. Thus, the probLem is soLved that in the useprocess of an existing resistivity Logging tooL, due to the factors of poor insuLating seaLing performance, downhoLe vibration impact and the Like, the measurement effect is affected.

The embodiment of the invention provides an automobile, a battery module and a manufacturing process thereof, and relates to the technical field of batteries. The battery module comprises a battery cell assembly, a busbar, an end plate assembly, a shell assembly and a filling body, the end plate assembly is connected with the shell assembly to define a cavity, the battery cell assembly is arrangedin the cavity and electrically connected with the busbar, and the filling body is at least filled between the busbar and the battery cell assembly, at least wraps a tab of the battery cell assembly and is used for supporting and positioning the tab. The manufacturing process provided by the embodiment of the invention is simple and good in integrity, and is beneficial to improving the vibration impact resistance in the use process.

The invention relates to a high-density plug connector with a bent tail accessory. The high-density plug connector with the bent tail accessory comprises a plug and a bent tail accessory matched withthe plug, wherein the plug and the tail accessory achieve fixation and adjustment of a cable outgoing angle through a positioning ring and a pin. The connector is simple in structure, compact in size,high in contact density and small in occupied space, and can meet the use of any required cable outgoing angle.

The invention belongs to the field of magnetic confinement fusion (MCF) technologies, and particularly relates to an ultrahigh vacuum sealing flange structure for a non-circular channel of a large Tokamak vacuum chamber. The structure comprises a concave flange, a convex flange and a connecting pipe. Two matched 90-degree sealing steps are machined on the inner sides of the opposite end faces of the concave flange and the convex flange, and a copper wire ring is placed between the two sealing steps, so that a gap is reserved between the concave flange and the convex flange in the axial direction; and the concave flange and the convex flange are connected through a double-end threaded pin or a double-end stud. By means of the structural mode that the oxygen-free copper wire is compressed through the 90-degree sealing steps, the ultrahigh vacuum sealing requirements of non-circular channel window flanges of different shapes can be met, and the machining and maintaining difficulty of thesealing face of a non-circular window is reduced.

The invention discloses an anti-vibration and shock transformer, comprising a shell, a silicon steel sheet group, a coil, a skeleton, a primary lead that is positioned on the upper skeleton and extends out of the shell upwardly, and a secondary lead that is positioned on the lower skeleton and extends out of the shell downwardly, wherein the secondary lead is used as a signal pin of the transformer to form an elastic needle, the effective length of the pin can be increased, and the rigidity of the pin can be reduced; and thus the transformer can be isolated from related signal pads on a PCB, and the phenomenon that the vibration and shock force of the transformer causes damage to the pads and related traces on the PCB can be prevented. In addition, flexible glue is injected in the transformer shell, and thus internal components of the transformer can be isolated from the shell, a fixed connection between the shell and the PCB is added, the vibration amplitude of the internal componentsof the transformer can be effectively reduced, and the damage to the transformer body caused by the vibration and shock force can be prevented.
