The utility model discloses a kind of self-adapting caliber adjustment oil carbon detector, including oil tank interface pedestal, sliding arc piece set, movable arc piece, positioning member, sensor and electronic information transmission module;More than three groups of sliding arc piece set are evenly distributed in oil tank interface pedestal along the circumference of oil tank interface pedestal, and sliding arc piece set slides along the radial direction of oil tank interface pedestal;Movable arc piece is inserted in the gap between adjacent sliding arc piece set, movable arc piece can slide along the gap between sliding arc piece set, cooperate with sliding arc piece set to realize caliber adjustment, and realize locking positioning by the positioning member located in the inboard of sliding arc piece set;Sensor is located in oil tank, and is electrically connected with the electronic information transmission module outside oil tank interface pedestal by wire.This utility model can adjust caliber, solve the problem that existing fixed caliber oil carbon table is poor in adaptability and high in procurement cost.

This application provides a vehicle body connection assembly and a vehicle. The vehicle body connection assembly includes: a floor (1) with a through groove (11); a sill beam (2) located on one side of the floor (1) along a first direction (x), the sill beam (2) being used to connect the vehicle body; a mounting side beam (3) connected to the side of the sill beam (2) near the floor (1); and a battery (100) located at least partially below the floor (1) and mounted along the first direction (x) on the side of the mounting side beam (3) away from the sill beam (2). The battery (100) includes a housing assembly (101), the housing assembly (101) including an upper housing (101A), the upper housing (101A) closing the through groove (11).

The utility model discloses a liquid packaging machine sealing device which comprises a device supporting seat, first linear modules are arranged on the two sides of the device supporting seat, and a fixing position is arranged on the device supporting seat; the mounting seat is placed in the fixing position, and a liquid packaging bag needing to be sealed is placed in the mounting seat; and the sealing assembly is arranged at the movable end of the first linear module, and heat sealing treatment is conducted on the liquid packaging bag through the sealing assembly. According to the sealing device, the supporting seat provides a stable foundation for the whole sealing device, it is guaranteed that all assemblies are kept stable in the working process, and sealing errors caused by vibration or unevenness are reduced; the first linear modules on the two sides enable the sealing assembly to stably move in the horizontal direction, and it is ensured that the uniform sealing effect is kept in the sealing process.

The utility model relates to the technical field of structural design of power equipment, and particularly provides a bus connecting device and a combined cabinet structure, the bus connecting device comprises a bus used for being connected with outgoing line terminals of two adjacent gas-insulated switchgears, and bus cylinders used for being respectively sleeved outside the outgoing line terminals of the two adjacent gas-insulated switchgears, and the bus cylinders are respectively sleeved outside the outgoing line terminals of the two adjacent gas-insulated switchgears. A current transformer is arranged outside the bus, the current transformer is located between the bus cylinders on the two sides, the two ends of the current transformer and the bus cylinders on the two sides are assembled in an inserted and sealed mode, a measuring coil is poured in the current transformer, the current transformer and the bus are integrally formed through pouring, and the space interval between the current transformer and the bus is eliminated. The current transformer is attached to the bus, and the current transformer does not move in the vertical direction under the condition that vibration is generated during opening and closing of the gas-insulated switchgear, so that the sealing and insulating effects of the current transformer and the plugging and sealing assembly positions of the bus cylinders on the two sides are good, and the leakage of insulating gas is avoided.
