Description
Technical field
The utility model is related to engine fluid-flywheel clutch technical fields, more particularly to a kind of heat conduction for fusible plug
Copper frame and its handling instrument.
Background technology
Fusible plug is that i.e. fusing, opening channel make fluid at a higher temperature using the low melting point fusible metal in device
Pressure of releasing is ejected from the hole for the fusible metal filled originally.
It is a kind of fusible metal (fusible metal alloy) of filling, the fusible metal heat conduction of low melting point in existing fusible plug
Relatively slow, fluid-flywheel clutch shell is usually irony or aluminium alloy, and heat-transfer rate is also unhappy, cause melting time of fusible metal compared with
It is long, superheat protecting function cannot be effectively acted as in due course.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, a kind of overheating protection effect is provided and is preferably used for
The conduction copper frame and its handling instrument of fusible plug.
What the purpose of this utility model was realized in：
A kind of conduction copper frame for fusible plug, the conduction copper frame includes mandrel, and the middle part of the mandrel is equipped with radius
The screw thread for the axially extending bore screw-thread fit with fusible plug is arranged in the periphery of larger connection bulge loop, the connection bulge loop,
Be arranged on the connection bulge loop it is several for molten metal by flowing hole, the circumferential surface of the mandrel is equipped with several along mandrel axis
To the heat conduction fin of extension, the flowing hole is located in sector, each flowing hole between adjacent heat conduction fin.
Preferably, four heat conduction fins are arranged on the mandrel circumferential surface at the connection bulge loop both ends.
A kind of handling instrument of conduction copper frame for fusible plug, including bar portion, one end of the bar portion are provided with several
Limit foot loads and unloads conduction copper frame for being inserted into the gap between adjacent heat conduction fin.
By adopting the above-described technical solution, the utility model has the advantages that：
The heat transfer rate of conduction copper frame is fast, and fusible metal column is allow to rapidly enter molten condition, plays overheat in due course and protects
The effect of shield, and copper frame can recycle, and reduce the usage amount of molten metal, reduce use cost.

Reference numeral
In attached drawing, 1 is mandrel, and 2 be connection bulge loop, and 3 be flowing hole, and 4 be heat conduction fin, and 5 be bar portion, and 6 be limit foot；21
It is screw rod interconnecting piece for head, 22,23 be sealing ring.
Specific implementation mode
Referring to Fig. 2-Fig. 4, a kind of conduction copper frame for fusible plug, a kind of conduction copper frame for fusible plug is described to lead
Hot copper frame includes mandrel, and the middle part of the mandrel is equipped with the larger connection bulge loop of radius, the periphery setting of the connection bulge loop
For the screw thread of the axially extending bore screw-thread fit with fusible plug, it is described connection bulge loop on be arranged it is several for molten metal by mistake
The circumferential surface of discharge orifice, the mandrel is equipped with several heat conduction fins axially extending along mandrel, and the flowing hole is in sector, each overcurrent
Hole is located between adjacent heat conduction fin.In the present embodiment, four are arranged on the mandrel circumferential surface at the connection bulge loop both ends
A heat conduction fin.
A kind of handling instrument of conduction copper frame for fusible plug, including bar portion, there are four one end settings of the bar portion
Limit foot rotates bar portion, loads and unloads conduction copper frame for being inserted into the gap between adjacent heat conduction fin.
Referring to Fig. 1, fusible plug includes cock body, and the cock body includes cross section in the head of regular hexagon and takes shape in head
The screw rod interconnecting piece of portion one end.The head end face adjacent with screw rod interconnecting piece forms annular groove, and setting is close in annular groove
Seal, the sealing ring protrude outside annular groove.One end end that the sealing ring protrudes outside annular groove is arc-shaped.It is set in the cock body
It is threaded hole to have axially extending bore, the axially extending bore, and conduction copper frame, the conduction copper frame and axial direction is arranged in the axially extending bore
Gap filling fusible metal (not shown) between through-hole hole wall.
Finally illustrate, preferred embodiment above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, to the greatest extent
Pipe has been described in detail the utility model by above preferred embodiment, but those skilled in the art should manage
Solution, can in the form and details make it various changes, without departing from the utility model claims book institute
The range of restriction.
