Description
Technical Field
The utility model relates to a hot air circulation rotary furnace door handle field indicates a hot air circulation rotary furnace's door handle connection structure especially.
Background
The hot-blast rotatory stove furnace gate is through the furnace door handle and the hasp screens closes the furnace gate, and the furnace door handle often rotates when the switch, and furnace door handle position ambient temperature and humidity of locating are higher moreover, and the design requires that the furnace door handle structure can stand high temperature and high humidity and tests, and the hard condition of rotatory handle produces when avoiding causing the furnace gate switch because of furnace door handle structure. In order to solve the problem, the existing scheme is to add grease lubrication to the friction position in the handle structure of the stove door. The defects of the existing scheme are that the furnace door is at high temperature, grease is consumed after long-time use, metal in the rear handle structure is oxidized after long-time placement under high humidity, and the situation of frequent occurrence of furnace door blockage or very labor-consuming opening and closing of the furnace door is realized after reuse.
Disclosure of Invention
In order to solve the problem, the utility model provides a door handle connecting structure of a hot air circulation rotary furnace, which is labor-saving in rotation and can withstand high temperature and high humidity tests.
In order to achieve the above object, the utility model adopts the following technical scheme: a door handle connecting structure of a hot air circulation rotary furnace comprises a furnace body, a furnace door movably connected with the furnace body and a door handle arranged on the furnace door, wherein the door handle comprises a handle, a rotating shaft, a rotating rod, a lock catch movably connected with the rotating rod, a bearing device and a decorative cover; the rotating shaft comprises an extending part and a protruding part, the extending part is positioned in the furnace door, and the protruding part is positioned outside the furnace door; the decorative cover is sleeved at the position where the extending part of the rotating shaft is tightly attached to the furnace door, and one end of the bearing seat close to the first bearing is sleeved; the rotating rod is sleeved at the top end of the extending part of the rotating shaft and rotates along with the rotating shaft to drive the lock catch to open or close the door.
Further, the first bearing and the second bearing are high temperature bearings.
Furthermore, the extension part is provided with a second through hole, the handle penetrates through the second through hole, is vertically intersected with the extension part of the rotating shaft, and is fixed through a pin.
As another technical scheme, the handle is arranged at the tail end of the extension part and is integrally designed with the rotating shaft, and the handle and the rotating shaft form a ninety degree angle.
The beneficial effects of the utility model reside in that: the high-temperature bearing is added to assist the rotation of the rotating shaft, when the door is opened, the door can be opened only by slightly rotating the door handle, the door is more labor-saving, the high-temperature bearing plays a lubricating role, and can also withstand high temperature and high humidity tests, so that the service life of the door handle is prolonged; the furnace gate transports comparatively steadily when the switch, and the collision of furnace gate and furnace body is little, avoids producing the striking noise, and is safe durable.
