Description

Technical Field

[0001] The utility model belongs to the technical field of oil furnace heat insulation, and in particular relates to an oil furnace heat insulation wrapping sleeve with a buckle structure. Background Art

[0002] The oil furnace directly inserts the electric heater into the organic carrier (heat transfer oil) for direct heating, and uses a high-temperature oil pump to circulate the liquid phase through the pipeline to transport the heated heat transfer oil to the heat-using equipment, and then returns to the electric oil furnace for heating from the oil outlet of the heat-using equipment, forming a complete circulation heating system. When transporting the heat transfer oil to the heat-using equipment through a pipeline, it is necessary to wrap the back of the pipeline with an insulating sleeve to make the pipeline have good thermal insulation performance, prevent people from accidentally touching and scalding, and reduce safety hazards in the workplace.

[0003] Existing, the heat insulation wrapping sleeve wrapped around the oil furnace pipeline is generally an aluminum foil reflective film as the outer layer, and the aluminum foil reflective film is filled with heat insulation cotton, so that the heat insulation wrapping sleeve has a certain softness, and the heat insulation wrapping sleeve is wrapped on the surface of the pipeline. After wrapping, the heat insulation wrapping sleeve is tightly wound around the pipeline surface by using materials such as metal wire or iron wire, so that the heat insulation wrapping sleeve fixes the pipeline surface for heat insulation and heat preservation. However, the metal wire or iron wire needs to be manually wound and tightened on the pipeline surface by tools, which increases the complexity of the installation process. When the heat insulation wrapping sleeve needs to be disassembled or adjusted later, it is also quite troublesome to untie the metal wire or iron wire, which makes it inconvenient to disassemble and assemble the heat insulation wrapping sleeve.

[0007] A transmission box, which is arranged at one end of the wrapping sleeve and is used to roll and bend the wrapping sleeve. A rotating rod is rotatably connected in the transmission box, and the rotating rod rotates to drive the transmission wheel to rotate, so that the transmission wheel engages with the toothed belt to drive the wrapping sleeve to roll and bend;

[0008] The buckling assembly is arranged at the bottom of the transmission box and is used to fix one end of the wrapping sleeve after winding and bending. The clamping plate of the buckling assembly is clamped with the toothed belt on the surface of the wrapping sleeve so that the clamping plate clamps and fixes one end of the wrapping sleeve after winding and bending.

[0009] Preferably, the snap-fit ​​assembly includes a snap-fit ​​shell and a snap-fit ​​rod, the snap-fit ​​shell is fixedly connected to the bottom of the transmission box, the snap-fit ​​rod movably penetrates the snap-fit ​​shell, and a movable plate is fixedly penetrated on the snap-fit ​​rod located in the snap-fit ​​shell, and both sides of the movable plate are slidably connected to the snap-fit ​​shell.

[0010] Preferably, a spring is sleeved on the clamping rod, one end of the spring is fixedly connected to the clamping housing, and the other end of the spring is fixedly connected to the movable plate.

[0011] Preferably, the clamping plate is fixedly connected to one end of the clamping rod located outside the clamping shell, and a plurality of teeth are provided on the surface of the clamping plate, and the teeth are engaged with the toothed belt.

[0012] Preferably, a threaded hole is provided on the surface of the clamping rod and a bolt is threadedly connected in the threaded hole. The bolt is a hand-tightened bolt so that the bolt can be manually screwed without tools.

[0013] Preferably, the transmission wheel is fixedly sleeved on the middle part of the rotating rod and a plurality of cone columns meshing with the toothed belt are provided on the surface of the transmission wheel.

[0014] Preferably, a groove is provided on the surface of the transmission box and slide grooves are provided at both ends of the groove, and slide bars are provided on both sides of the bandaging sleeve.

[0016] (1) The side of the wrapping sleeve without the toothed belt is brought into contact with the pipe and the pipe is wrapped. After wrapping the pipe, one end of the wrapping sleeve is inserted into the groove on the surface of the transmission box. After being inserted into the groove, the slide bars on both sides of the wrapping sleeve can move in the slide groove. At this time, the rotating rod is rotated, and the rotation of the rotating rod drives the transmission wheel to rotate. The tapered column on the surface of the transmission wheel engages with the toothed belt to drive the wrapping sleeve to be rolled and bent into the transmission box. Under the action of the slide bar sliding guide in the slide groove, the wrapping sleeve is gradually reduced in size and the pipe is tightly wrapped, so that it is more convenient to wrap the pipe, avoiding the problem of manually fixing the wrapping sleeve on the pipe surface by repeatedly winding and tightening the wire through tools.
