The special battery assembly frame has the advantages that the front tightening bar is locked through the side hook lock assembly and the upper hook lock assembly, and the front surface and the front top part of the battery which is installed in the assembly frame can be tightened, so that the battery can be prevented from playing in the assembly frame; the upper end part of the rear baffle plate is fixedly provided with a limiting pressing plate assembly, so that the rear top end of the battery can be limited, and the battery can be further clamped; and the anti-loosening mechanism is arranged in the side hook lock assembly, so that the side hook lock assembly can be prevented from being unlocked or loosened in the severe vibration, and the tightening effect of the front tightening bar on the battery can be guaranteed.

The invention discloses a solid wall pipe distribution fixing connector which comprises a bucket-shaped outer barrel and a screw rod, wherein the bucket bottom of the outer barrel is provided with a via hole; the thread end of the screw rod extends into the outer barrel through the via hole; a fixed bulge plug and a movable bulge plug are sequentially arranged in the outer barrel from inside to outside, the fixed bulge plug is sheathed on the screw rod in a sliding way, and the movable bulge plug is connected onto the screw rod by thread; the fixed bulge plug and the movable bulge plug are respectively in a circular truncated cone shape; the small end surface of the fixed bulge plug is opposite to the small end surface of the movable bulge plug; a bulge barrel is arranged in the outer barrel; the inner walls of the two ends of the bulge barrel are respectively provided with an inner conical surface, and the two inner conical surfaces are respectively matched with the outer surface of the fixed bulge plug and the outer surface of the movable bulge plug. The solid wall pipe distribution fixing connector is simple in structure; the bulge barrel can be extruded outwards by the fixed bulge plug and the movable bulge plug by operating the screw rod, so that the functions of extruding and closely supporting a pipeline can be reached, and a whole longer pipe can be dragged and drawn; the solid wall pipe distribution fixing connector is simple and convenient to operate, is capable of effectively accelerating the construction speed, lightening the labor intensity and improving the operation efficiency, and is safe, convenient and fast.

The invention belongs to the technical field of building materials, in particular relates to an assembling method of a modular combined heat preservation curtain wall plate. A baseplate is horizontally placed on a standard level working platform, and adhesive is smeared between two clamping strips on the inner sides of the four aluminum profile edges forming a aluminum alloy frame; four end surfaces of the baseplate are embedded between the two clamping strips of the inner sides of the aluminum profile edges respectively, two ends of the aluminum profile edges are inclined edges with the angle of 45 degrees, the adjacent aluminum profile edges incline for 45 degrees and are connected with each other to form an aluminum alloy frame, and the intersection angle of the aluminum alloy frame is 90 degrees. The method can adopt manual and semi-mechanized assembly, facilitates the realization of automated and large-scale assembly, can flexibly adjust the various steps according to the actual requirement and is applied to different production enterprises, and control is performed by adopting a tool in the construction process, so that the geometric dimension of a product can be controlled better. Fastening lock plates are used for fixing the aluminum alloy frame, and the problem of deformation of the aluminum alloy frame caused by welding and riveting is solved due to the use of the fastening lock plates.
