The utility model discloses a kind of pretreatment toolings of fireproof glass fiber cloth construction, including rack, the reel is set on the one end of the rack, to be constructed fireproof glass fiber cloth is wound on the reel surface, two flattening components are set on the rack;Among them, with reel rotation, after pulling fireproof glass fiber cloth, glass fiber cloth is rolled by flattening component, realize the elimination of the wrinkle on the surface of fireproof glass fiber cloth.Driving third pulley rotation, let second transmission belt drive fourth pulley rotation, let two second compression roller further again roll pressure fireproof glass fiber cloth, fireproof glass fiber cloth after flattening can be closely combined with base layer, make surface more level, beautiful, avoid the situation that appearance is influenced, such as wrinkle, blister, and make fireproof glass fiber cloth better with base layer or other material contact, improve adhesion, ensure that it is firmly fixed in required position.

This invention relates to the field of battery trays, and more particularly to a battery tray lifting lug connection structure and its connection method. Specifically, it discloses a battery tray lifting lug connection structure, comprising: a tray frame and a lifting lug sleeve. A through mounting groove is formed on one end face of the tray frame, and the lifting lug sleeve is interference-fitted into the mounting groove. An adhesive layer is filled between the contact surfaces of the lifting lug sleeve and the tray frame. Unlike welding in the prior art, this application uses an interference fit for fixing, followed by adhesive bonding for reinforcement. This eliminates the need for welding during processing, avoiding defects associated with welding and facilitating application in industrial production lines. The assembly process design does not require consideration of the impact of material parameters on welding, improving production efficiency and resulting in a smoother and more aesthetically pleasing product surface.

The utility model relates to a box body structure of an isolating switch operating mechanism, which is characterized by comprising a box body, a fixed sealing plate, a first side opening door, a second side opening door and an inner locking mechanism, according to the utility model, the side door of one side face of the isolating switch operating box, which is opposite to the operating mechanism, is opened internally, so that the condition that the side door is opened from the outside and misoperation is caused is avoided; in addition, under the condition that the first side door is opened, the second side door is opened by loosening the limiting bolt and releasing the torsion of the torsion spring to realize the popping of the spring bolt piece, and under the condition that the first side door is not opened, the second side door cannot be opened from the outside, so that the safety of the second side door is improved. And the lock head on the second side-opening door is matched with the lock tongue piece in an inclined plane matching manner, so that the sealing strip in the closed state of the second side-opening door can be ensured to be in an extruded state, and the sealing, waterproof and dustproof effects of the isolating switch operating box are ensured.
