Wire casing.
Background technology
In the prior art, fire-bar is being loaded after runner plate, it is necessary to which fire-bar is fixed on into runner with the mode of riveting
In plate as depicted in figs. 1 and 2.Due to there is a segment distance between adjacent riveting point, thus can cause between two neighboring riveting point
Fire-bar can not be contacted well with runner plate, reduce heat transfer efficiency so that need more energy consumptions can be only achieved
Design requirement.Further, since existing runner plate is smooth, fire-bar and runner plate can be caused after fire-bar expanded by heating
Between loose contact, reduce heat transfer efficiency, cause energy consumption increase and product defects.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of fire-bar hookup wire of runner plate
Groove, the back-off that limiting section turns into wire casing fix to fire-bar, and fire-bar keeps good with runner plate after installation
Contact, improve heat transference efficiency, reduce energy consumption.
The purpose of this utility model is achieved through the following technical solutions：The fire-bar installation wire casing of runner plate, institute
It is cylindrical structure to state fire-bar, and the wire casing includes loading unit, limiting section and installation portion successively from top to bottom, and the loading unit is drawn
The diameter that its minimal openings width when being in elastic limit is equal to or more than the fire-bar is stretched, the limiting section stretching is in bullet
Property the limit when its minimal openings width be equal to or more than the fire-bar diameter, the installation portion be central angle be more than 180 degree
Arc groove, the diameter of the arc groove is equal to the diameter of the fire-bar.
Preferably, the open top width of the loading unit is the maximum open width of loading unit.
Preferably, the open top width of the loading unit is equal to or more than the diameter of the fire-bar.
Preferably, the A/F of the loading unit tapers into from top to bottom.
Preferably, the cross section of the loading unit is inverted trapezoidal structure.
Preferably, the cross section of the limiting section is rectangular configuration or trapezium structure.
The beneficial effects of the utility model are：
（1）In the utility model after fire-bar is embedded in into installation portion, because installation portion is the circle that central angle is more than 180 degree
Arc groove so that the back-off that limiting section turns into wire casing fixes to fire-bar, avoids adjacent riveting in the prior art
The situation that fire-bar disengages with wire casing between contact, fire-bar keeps good contact with runner plate after installation, improves
Heat transference efficiency, reduce energy consumption；
（2）It is good that after fire-bar expanded by heating also fire-bar can contact the back-off that limiting section is formed with runner plate
It is good, avoid the situation that the heated caused heat transference efficiency of fire-bar declines；
（3）Loading unit is used to place fire-bar when fire-bar is embedded in into installation portion, prevents fire-bar stress from retrodeviating from mesh
Mark direction movement.

Embodiment
The technical solution of the utility model, but the scope of protection of the utility model are described in further detail below in conjunction with the accompanying drawings
It is not limited to as described below.
Embodiment one
As shown in Figure 3 and Figure 4, This embodiment describes a kind of fire-bar of runner plate to install wire casing, and the fire-bar 1 is
Cylindrical structure, the wire casing 3 include loading unit 31, limiting section 32 and installation portion 33 successively from top to bottom；Loading unit 31 is used for
Fire-bar 1 is placed when fire-bar 1 is embedded in into installation portion 33, prevents the stress of fire-bar 1 retrodeviates from being moved from target direction；Limiting section 32
For forming the back-off of wire casing 3, fire-bar 1 be embedded in installation portion 33 after fire-bar 1 is fixed, make fire-bar 1 with
Runner plate 2 is contacted well, so as to reduce energy consumption；Installation portion 33 is then used to provide an installing space for fire-bar 1, in this space
Interior fire-bar 1 contacts well with runner plate 2.When the loading unit 31 stretching is in elastic limit its minimal openings width be equal to or
More than the diameter of the fire-bar 1, ensure that fire-bar 1 can pass through loading unit 31, the limit in the presence of external forces
Its minimal openings width is equal to or more than the diameter of the fire-bar 1 when the stretching of position portion 32 is in elastic limit, ensures fire-bar 1
