Abstract
The utility model belongs to fire-resistant material, and mainly relates to the connection of the bottom of an integral type stopper-rod with a screw. The utility model is characterized in that a nut is fixed in a hole at the bottom of a bar body of the stopper-rod; a threaded hole of the nut is concentric with a core hole of the bar body; the threaded hole of the nut is larger than the core hole of the stopper-rod at the upper part of the nut. The utility model has simple installation and convenient operation. The screw is screwed in the nut; the nut and the screw have high matching precision and good connection intensity. The phenomena that the stopper-rod falls off, etc. can be ensured not to occur when the stopper-rod is used in the screw.
Description
The utility model belongs to refractory material, relates generally to the syndeton of integral column of sagger bottom and screw rod.
The integral column of sagger of prior art has two kinds of forms with the connected mode of screw rod :-kind be that screw rod is connected with the stopper internal thread by the refractory material wire connection head close with the stopper material; Another kind is that screw rod is connected by bearing pin with stopper.Preceding a kind of connected mode exists: 1, nipple is a carbon containing refractory, and it is easily oxidized to bear high temperature for a long time, and intensity descends significantly, causes stopper to come off; 2, the threaded engagement between the refractory material is lower than metal parts threaded engagement precision, and the gap is big, and inhomogeneous, and stopper is difficult for levelling; 3, use inconveniently, during use nipple is enclosed within on the connecting rod, be screwed into stopper afterbody internal thread, fix with clamp nut then, be fixed on the operating mechanism by two nuts up and down.Because connecting rod is nonexpondable metal parts, each installation all needs to load and unload clamp nut, and connecting rod bears high temperature for a long time, and easily oxidation and rusting causes the loading and unloading difficulty.The back is a kind of easily ruptures near the stopper pin-and-hole when installing, adjusting and using, and influences the use of stopper.
The purpose of this utility model provides a kind of being convenient to and connects, and is easy to use, is connected firmly, and do not influence the integral column of sagger of stopper intensity.
Integral column of sagger of the present utility model comprises barred body, it is characterized in that the interior hold-down nut of shoulder hole of barred body bottom, and the screwed hole of nut is concentric with barred body core hole, and the screwed hole of nut is greater than stopper core hole, nut top.
Stopper core of the present utility model hole is concentric shoulder hole, on the nut outer surface of fixing in its base apertures groove or boss is set.
The utility model is installed simple, and is easy to use, and screw rod is screwed into nut gets final product, and nut and screw rod quality of fit height, bonding strength is good, can guarantee phenomenons such as stopper comes off can not occur when screw rod uses in stopper.
The utility model is described in further detail below in conjunction with accompanying drawing:
Accompanying drawing is the structural representation of the utility model embodiment.
Among the figure, when making stopper, in core hole, the bottom of barred body 15, insert the metal nuts 2 concentric with barred body core hole.The surface of metal nuts 2 is provided with groove or boss, increases the degree of being connected firmly of metal nuts and stopper.When stopper need be connected and fixed, screwed screw rod 4 is cooperated with nut 2, again with clamp nut 3 fixing getting final product.
Claims (2)
1, a kind of integral column of sagger comprises barred body, it is characterized in that hold-down nut in the hole of barred body bottom, and the screwed hole of nut is concentric with barred body core hole, and the screwed hole of nut is greater than stopper core hole, nut top.
2, according to the described integral column of sagger of claim 1, it is characterized in that stopper core hole is concentric shoulder hole, on the nut outer surface of fixing in its base apertures groove or boss are set.
