SUMMERY OF THE UTILITY MODEL
In view of the above shortcoming of prior art, the utility model aims to provide a reinforced type flame retardant rod for solve among the prior art flame retardant rod easy fracture cause generator life weak point, problem with high costs.
In order to achieve the above and other related objects, the present invention provides a reinforced flame retardant rod, which comprises a ceramic fiber blank and a stainless steel frame, wherein the stainless steel frame is embedded in the ceramic fiber blank; the ceramic fiber blank is a hollow rod body and comprises a closed end and an open end; the stainless steel frame is formed by connecting a plurality of U-shaped stainless steel wires and a plurality of stainless steel rings; the U-shaped stainless steel wires extend longitudinally along the ceramic fiber blank and are uniformly crossed and fixed in the circumferential direction; the stainless steel rings are respectively fixed at the U-shaped end, the opening end and the middle part of the U-shaped stainless steel wire.
Preferably, the stainless steel frame is connected by welding.
Preferably, the stainless steel ring connected with the opening end of the U-shaped stainless steel wire is thicker than the stainless steel rings connected with other positions.
Preferably, the stainless steel frame is made of SUS309S stainless steel.
Preferably, the material used for the ceramic fiber blank is high-alumina ceramic fiber.
As described above, compared with the prior art, the utility model provides a reinforced type flame retardant bar, the stainless steel frame that welds in advance is embedded in flame retardant bar promptly, and the stainless steel frame plays the effect of fixing and supporting the ceramic fiber body in flame retardant bar, when flame retardant bar part has the damage, prevents that it from wholly droing from the generator. The reinforced flame-retardant rod is not easy to damage, long in service life, remarkable in heat-insulating and fireproof effects, greatly reduces the rejection rate of the generator and saves the cost.

Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
The drawings in the specification show the structure, ratio, size, etc. only for the purpose of matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and not for the purpose of limiting the present invention, so the present invention does not have the essential meaning in the art, and any structure modification, ratio relationship change or size adjustment should still fall within the scope of the present invention without affecting the function and the achievable purpose of the present invention. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.
As shown in fig. 1-2, the utility model provides a reinforced flame retardant rod, which comprises a ceramic fiber blank 1 and a stainless steel frame 2 embedded in the ceramic fiber blank 1, specifically an alumina type ceramic fiber blank and an SUS309S stainless steel frame. The ceramic fiber blank 1 is a hollow rod body, and comprises a closed end 11 and an open end 12. Stainless steel frame 2 inlays in the barred body of ceramic fiber body 1, including many U type stainless steel wires 22 and a plurality of stainless steel ring 21, U type stainless steel wire 22 is along ceramic fiber body 1 vertical extension and along the even cross arrangement of circumference, and this embodiment specifically is two U type stainless steel wires 22 that are the cross, accessible welding reciprocal anchorage, also accessible and stainless steel ring 21's welding reciprocal anchorage. The U-shaped end of the U-shaped stainless steel wire 22 is positioned in the closed end 11 of the ceramic fiber blank 1, the open end is positioned in the open end 12 of the ceramic fiber blank 1, and the stainless steel ring 21 comprises an open end stainless steel ring 211, a U-shaped end stainless steel ring 213 and a plurality of middle stainless steel rings 212 which are fixedly connected with the two ends and the middle parts of the U-shaped stainless steel wire 22 respectively, preferably in a welding mode. Preferably, the stainless steel ring 21 connected with the open end of the U-shaped stainless steel wire 22 is thicker than the stainless steel rings 21 at other positions, for example, the U-shaped stainless steel wire 22 and the stainless steel rings 21 at other positions are both in the specification of phi 4, and the stainless steel ring 21 connected with the open end is in the specification of phi 6, because the step at the open end of the flame retardant rod needs to be stressed, and the stainless steel ring at the open end is thicker than the steel wires used for the stainless steel ring at the open end in order to ensure that the whole body cannot fall down after the step is broken.
