The scheme is further as follows: the fireproof cloth is one of fireproof canvas or asbestos cloth.
The scheme is further as follows: the rib is 6, and 6 ribs encircle the top dish evenly distributed.
The scheme is further as follows: the rib is provided with an inward bending rib, the bending rib is bent at one third of the length of the rib from outside to inside, and the other end of the supporting rod is hinged with the bending part of the rib.
The scheme is further as follows: the inward bend angle is 20 to 30 degrees.
The utility model has the beneficial effects that: by utilizing the principle that the umbrella can be unfolded and folded, the retractable umbrella-shaped fire receiving hopper with the size of the opening capable of being controlled randomly is realized, and the use is convenient. The telescopic fire-catching device is retractable, easy to carry and high in flexibility, and is suitable for completing fire catching in common and complex fire-catching operation places.
The utility model is described in detail below with reference to the figures and examples.
