The invention discloses a building aluminum alloy solar heat collector which belongs to a solar energy utilization technology and comprises a plurality of heat collecting core boards, core board connecting plates, water outlet pipes arranged at the upper ends of the heat collecting core boards and the core board connecting plates, and water inlet pipes arranged at the lower ends of the heat collecting core boards and the core board connecting plates; the heat collecting core boards are connected between the water outlet pipes and the water inlet pipes; the core board connecting plates are inserted into side grooves of the heat collecting core boards; and a side upright is inserted into a slot of the heat collecting core board at the outermost side, insulating material layers with aluminumfoils are arranged at the back surfaces of the heat collecting core boards and the connecting plates, transparent insulation cover plates are inserted into clamping grooves of the water outlet pipe and the water inlet pipe, and side frames are connected to the left side and the right side of the heat collecting core boards. The invention has the advantages of simple structure, convenience for manufacture and light weight, ensures that a heat collector is integrated with a building wall body structure into a whole, can be used for producing hot water, and can be used as an insulation building material.

The invention discloses a making method of a range hood lock catch installing support. The making method of the range hood lock catch installing support is characterized in that the lock catch installing support is integrally drawn and formed by adopting a range hood body material, and then support installing holes are drilled in the integrally drawn and formed support; and the lock catch installing support is formed by a convex platform drawn from a range hood body. The making method of the range hood lock catch installing support has the advantages that making and assembling are easy, the surface is clean, and the cost is reduced.

The invention discloses an automatic air conditioner base bolt and base foot welding production system which comprises a conveying belt and a rack matched with the conveying belt. An air conditioner base plate feeding station, a screw feeding station, a screw welding station, a base foot feeding station and a base foot welding station are sequentially arranged on the rack in the air conditioner base plate machining direction, positioning templates are arranged on the stations, and station manipulators are installed on the rack. The automatic air conditioner base bolt and base foot welding production system is characterized in that the air conditioner base plate feeding station comprises a conveying belt and a correction device; the screw feeding station comprises a vibratory selecting machine, a screw distributor and an automatic bolt feeding device; the screw welding station comprises a screw welding machine; the base foot feeding station comprises an automatic base foot feeding device and a moving feeding trolley; the base foot welding station comprises a base foot double-end welding machine. The automatic air conditioner base bolt and base foot welding production system completely achieves automatic air conditioner base bolt and base foot welding, and the whole system enables labors to be saved, overcomes the shortcoming that the quality of an existing air conditioner base plate cannot be ensured and has the advantages of being capable of saving manpower and material resources, high in production process and free of insufficient solder.
