The invention discloses a metal inner tank structure of a membrane type cryogenic storage tank, comprising a tank bottom and a tank wall, the tank wall is welded by a base plate, the tank bottom is in an approximately circular structure, the tank bottom is spliced ​​by the base plate and The splicing gap is filled by the peripheral special-shaped plate. The base plate is composed of a basic unit or several basic units. The basic unit is composed of a flat plate and longitudinal waves and transverse waves on the plate. The longitudinal waves and transverse waves are both concave on one side. In the protruding arched structure, the longitudinal wave and the transverse wave are vertically interlaced and connected together through a smooth transition of a curved surface, and both the longitudinal wave and the transverse wave are in a smooth transition with the surrounding flat plates through a curved surface. The metal inner tank structure of the membrane cryogenic storage tank can avoid stress concentration during thermal expansion and cold contraction, and only a small number of molds are required for manufacturing, which can improve on-site assembly efficiency during assembly.

The invention discloses a quantitative filling device. The device comprises an identification code acquisition module for acquiring the identification code of a product to be filled, a control module and a filling module, wherein the control module is used for receiving the identification code of the product to be filled from the identification code acquisition module and calling a filling formula of the product to be filled according to the identification code of the product to be filled; according to the filling formula, the filling sequence of a plurality of oil filling points of the product to be filled and the filling quantity corresponding to each oil filling point are provided; and the filling module fills oil into a plurality of oil filling points of the product to be filled in corresponding quantities according to the filling sequence. The invention also discloses a quantitative filling method. By the quantitative filling device and the quantitative filling method, problems such as wrong filling and missed filling of the oil in the process of manufacturing automobiles are solved; the oil filling quality of the automobiles is guaranteed; the quantitative filling device is easy and convenient to operate, and the oil can be filled accurately, so that the on-site assembly efficiency is improved.

The invention discloses a tank bottom structure of a metal inner tank of a membrane type cryogenic storage tank. The bottom of the tank is approximately circular in structure. unit or several basic units, the substrate is welded or deep-drawn (deep-drawn), the basic unit is composed of a flat plate, a longitudinal wave and a transverse wave on the plate, and the longitudinal wave and the transverse wave are both recessed on one side In the protruding arched structure, the longitudinal wave and the transverse wave are vertically interlaced and connected together through a smooth transition of a curved surface, and both the longitudinal wave and the transverse wave are in a smooth transition with the surrounding flat plates through a curved surface. The tank bottom structure of the metal inner tank of the membrane cryogenic storage tank can avoid stress concentration during thermal expansion and contraction, and only a small number of molds are required for manufacturing, which can improve on-site assembly efficiency during assembly.

The invention discloses a beam-column joint of a layered assembled steel structure, which comprises an upper-layer column (1), a lower-layer column (2), and a main beam (1) installed between the upper-layer column (1) and the lower-layer column (2). 3); a middle column (5) is welded at the junction of the main beam (3) with the upper column (1) and the lower column (2), and a main beam (3) is welded on one side of the middle column (5), Its upper and lower ends are respectively welded with an upper flange (51) of a central column and a lower flange (52) of the central column, and the bottom of the upper column (1) is welded with an upper column that is opposite to the upper flange (51) of the central column. A flange (11), the top of the lower column (2) is welded with a lower column flange (21) which is connected with the lower flange (52) of the central column. The invention has simple structure, direct force transmission, clear force of each part, convenient industrialized manufacturing and on-site assembly, greatly reduced on-site assembly workload, improved on-site assembly efficiency, and low comprehensive cost.

An optical connector, comprising: a pipe-through assembly, the pipe-through assembly has at least one protrusion; a housing assembly sleeved on the outside of the pipe-through assembly, and the housing assembly has a structure for the pipe-through assembly to pass through along a first direction The first channel; the shell assembly also has a first limiting structure, the first limiting structure has a limiting surface and a positioning surface, the limiting surface is used to abut against the end surface of the protrusion, and is used to pass through the pipe assembly relative to the shell. After the body assembly is rotated, the pipe threading assembly is limited along the second direction opposite to the first direction; the positioning surface is used to abut against the raised surface, and is used to align the pipe threading assembly and the pipe threading assembly along the circumferential direction of the pipe threading assembly. The housing assembly is limited. The optical connector is provided with a first limiting structure on the housing component, and after the tube passing component is rotated relative to the housing component, the abutting relationship between the first limiting structure on the housing component and the protrusion is used to form the through tube component The limit can reduce the difficulty of assembling the optical connector, thereby improving the efficiency of on-site assembly.
