The soft package battery cell comprises a packaging bag, an electrode assembly, an electrode terminal and a first insulating piece, the electrode assembly is provided with a tab portion at the end thereof along a third direction, the electrode terminal is welded with the tab portion and forms a first connecting portion, the area of the first connecting portion is 20mm 2 to 60mm 2 , the first insulating piece surrounds the electrode terminal and is arranged between the electrode terminal and the packaging bag, the first insulating piece is sealingly connected with the packaging bag and forms a second connecting portion, and the minimum distance between the first connecting portion and the second connecting portion along the third direction is 2mm-7mm.

This utility model provides a node connection structure between prefabricated building exterior wall components and floor slabs, including exterior wall components, with several sleeve groups at the bottom of the exterior wall components, each sleeve group including several sleeves, and several grouting holes communicating with the sleeves on the side of the exterior wall components; floor slabs, with several embedded reinforcement groups inside the floor slabs, each embedded reinforcement group including several embedded reinforcements, one end of which extends out from inside the floor slab and is inserted into the sleeves; wherein, between two sleeve groups, the exterior wall components also have several spaced-apart reserved tooth groove groups, and between adjacent two embedded reinforcement groups, the floor slab also has several spaced-apart positioning tooth groups, with a first wedge surface abutting against a second wedge surface, and a protrusion being engaged in a limiting groove. By engaging the positioning teeth on the floor slab with the positioning tooth grooves on the exterior wall components, the horizontal positioning between the floor slab and the exterior wall components is achieved, which can reduce the horizontal movement of the exterior wall components relative to the floor slab and improve installation accuracy.

The application discloses a kind of based on low temperature embrittlement cooperates prefabricated mark guide plate stamping equipment, including base and the shelf plate of being movably arranged on base, the holding module for being clamped and positioning outside the processing area of tensioning the plate to be processed of outside the plate to be processed is arranged between the base and shelf plate, and the groove prefabricated module for processing V-shaped guide groove to outside the plate to be processed preset fracture zone, the low-temperature cooling module for the plate after being processed by groove prefabricated module is arranged on the side of base, to reduce the temperature of plate and maintain low-temperature atmosphere by being used for rapid cooling, and the control cabinet for being respectively communicated connection control with holding module, groove prefabricated module and low-temperature cooling module.The application solves the problem that traditional stamping process handles high-strength alloy plate and the outer ring component of difficult deformation material, because prefabricated mark processing, low-temperature treatment and stamping forming link discrete layout lead to parameter matching, low-temperature embrittlement uncontrollable, difficult to realize the problem of accurate control of fracture surface quality.

The application relates to a vehicle stove and a vehicle, which comprise a box body, an open side of the box body being provided with an opening; a connecting rod mechanism is installed in the box body, one end of the connecting rod mechanism is connected to an inner wall of the box body, and the other end of the connecting rod mechanism is connected with a receiving plate, the receiving plate is installed with a stove cooker; a tableware storage cavity is formed between the receiving plate and an inner bottom wall of the box body; the receiving plate can be moved out of the box body through the connecting rod mechanism from the opening. When a driver has a demand for cooking and cooking, the receiving plate can be pulled out of the vehicle body, the stove cooker is moved out of the opening through the connecting rod mechanism, and cooking is performed; when the stove cooker is in a storage state, the receiving plate and the inner bottom wall of the box body have a tableware storage cavity, have a certain storage space, and can store tableware and other articles; if the tableware in storage is in contact with the receiving plate, the tableware and the stove cooker can be reduced in movement in the box body during vehicle driving, and noise can be reduced.

The application relates to a coating device for tufting carpets, which comprises a rack, a motor arranged on the rack, a base cloth roller detachably connected with an output shaft of the motor through a shaft coupling, an auxiliary assembly arranged on the rack, the auxiliary assembly comprising a rotating shaft rotatably connected with the rack, opposite sides of the rotating shaft being provided with roller placing frames, both ends of the base cloth roller being arranged in the roller placing frames, openings being arranged on the roller placing frames, and a driving piece arranged on the rack and used for driving the roller placing frames to rotate around the axis of the rotating shaft. The application has the effect of improving the efficiency of workers in replacing the base cloth roller.
