The utility model discloses a cable explosion -proof box belongs to cable equipment technical field, including mounting spare and glue injection spare, two mounting spares can be relatively buckled and detachable connection to form explosion -proof box body, and the inside of explosion -proof box body forms sealed cavity, and the both ends of sealed cavity are provided with fixed line passageway, and fixed line passageway one end communicates sealed cavity, and the other end communicates outside, and fixed line passageway and sealed cavity coaxial setting, glue injection spare fixed connection in any mounting spare, and the glue injection passageway of being through being provided on glue injection spare, and glue injection passageway communicates sealed cavity with outside, is used to inject solidified explosion -proof glue in sealed cavity. The cable explosion -proof box through the design of mounting spare and glue injection spare, has realized the assembly of cable explosion -proof box convenientization and has dismantled, has effectively promoted the sealing and explosion -proof performance to cable and junction box interface, has guaranteed the stable safe operation of cable and related equipment.

This utility model discloses a twist hook adaptable to ropes of varying thicknesses, comprising a fixing base and a winding unit. The winding unit includes a top cover, a drive component snapped into the inside of the top cover, a stator connected to the drive component via a rope drum, and a clutch component snapped between the stator and the top cover. The clutch component is used to cooperate with the top cover to prevent one-way reverse rotation. The drive component is used to cooperate with the top cover to drive the rope drum to rotate and wind the rope. The clutch component is fixedly connected to the stator. The rope drum is provided with at least two sets of rope threading structures, which are used to thread at least two different rope diameters respectively. The winding unit is connected to the fixing base via the stator. This utility model ensures the stability of the connection between the components, effectively preventing the components from loosening and falling off during the transfer process, thereby greatly saving assembly time, ensuring smooth assembly, making rope threading smoother, saving rope threading time, and ensuring the normal daily use of the twist hook.

This disclosure relates to a non-metallic elastic sealing ring, a soft-seal oil pump, and a sealing method. The non-metallic elastic sealing ring includes a non-closed ring body; the upper surface of the non-closed ring body is provided with a wedge-shaped groove structure; the non-metallic elastic sealing ring is disposed on the plunger of the soft-seal oil pump. During the upstroke, the pressure of the liquid on the upper part of the non-metallic elastic sealing ring acts on the wedge-shaped groove, decomposes into a circumferential force, causing the sealing ring to expand and deform, completely fitting with the pump barrel, strengthening the seal between the plunger and the pump barrel, maintaining pump efficiency, and simultaneously playing a role in scraping sand and scale, preventing pump jamming; during the downstroke, after the pressure on the upper and lower surfaces of the plunger is balanced, the sealing ring contracts back to its initial state, the gap between the plunger and the pump barrel increases, reducing the downward resistance caused by the high viscosity of the liquid during the downstroke, slowing down the bending of the sucker rod, extending the service life of the rod tube, extending the pump inspection cycle, and reducing production costs.
