The utility model provides a multinational converter, comprising a socket, one side surface of which is provided with an accommodating groove; the plug is assembled in the containing groove in a sliding mode in the first direction, the socket is further provided with a limiting structure, the limiting structure is used for preventing the plug from being separated from the containing groove in the second direction, and the second direction is perpendicular to the first direction; and the locking assembly comprises a first connecting assembly and a second connecting assembly which are arranged on the plug and the socket respectively, and the first connecting assembly and the second connecting assembly are detachably connected. The plug is locked in the accommodating groove of the socket through the first connecting assembly and the second connecting assembly, so that the plug and the socket are mutually fixed; moreover, the plug is prevented from being separated from the accommodating groove along the second direction through the limiting structure, the connection stability and firmness between the plug and the socket are improved, and the phenomenon that the plug is easy to loosen in the accommodating groove is avoided.

The application discloses a sample container which comprises a main body, a middle cover and an upper cover. The main body is provided with a cavity for storing samples and a cavity opening communicating with the cavity. The middle cover is arranged on the main body and partially covers the cavity opening. The middle cover is provided with a sample inlet channel communicating with the cavity and the outside. The outer peripheral wall of the middle cover is provided with a first limiting portion and a first guide portion. The first limiting portion is located between the first guide portion and the communication position of the sample inlet channel and the outside. The side of the first guide portion facing the first limiting portion is formed with a first guide surface. At least part of the surface of the guide surface is provided in a slope or arc shape. The upper cover is detachably arranged on the middle cover and covers the sample inlet channel. The inner peripheral wall of the upper cover is provided with a second limiting portion and a second guide portion. The second limiting portion is connected with the first limiting portion. The second guide portion is in abutting limiting connection with the first guide portion. The sample container provided by the application has higher efficiency in sample adding operation.

The utility model discloses an electrode assembly and a battery cell, and relates to the technical field of batteries. The electrode assembly comprises a diaphragm, at least two positive pole pieces and at least two negative pole pieces; a negative pole piece is arranged between any positive pole piece and the adjacent positive pole piece; a diaphragm is arranged between any negative pole piece and the adjacent positive pole piece; the first surfaces of the positive pole piece and / or the negative pole piece are / is sunken along the stacking direction of the electrode assembly, and bulges are formed on the opposite second surfaces of the positive pole piece and / or the negative pole piece. The protrusions are arranged on the surfaces of the pole pieces, the pole pieces and the diaphragm are stacked to form the electrode assembly, and after the electrode assembly is subjected to hot pressing, the protrusions on one pole piece can extrude the diaphragm and form the grooves in the other adjacent pole piece, so that mutual fixation between the pole pieces is achieved, the phase difference between the pole pieces is prevented from changing, and the reliability of the battery is improved. And the structural stability and performance of the battery are improved.

The utility model discloses a sealing bottle cap and a packaging bottle, the sealing bottle cap comprises a cap body, the bottom side of the cap body is provided with a lower opening, and the inner side of the cap body is provided with an inner connecting structure; the sealing plug comprises a connecting section, a deformation section, an outer supporting section and a plugging section which are coaxially connected in sequence from inside to outside, the connecting section is connected to the inner top side of the cover body, and the plugging section is located at the top of the outer supporting section; the deformation section can drive the plugging section to leave the inner top side of the cover body in a natural state and enable the outer diameter of the outer supporting section to be reduced, and when the plugging section moves upwards, the deformation section can be driven to elastically deform and enable the outer diameter of the outer supporting section to be increased. The outer diameter of the outer supporting section can be increased to ensure the sealing performance with the bottle opening, and the outer diameter of the outer supporting section can be reduced to reduce the friction force when the outer supporting section is separated from the bottle opening, so that the operation is more labor-saving, and the sealing performance and the operation convenience when the sealing bottle cap is used are better considered.
