Description
Technical field
The utility model is related to engine fluid-flywheel clutch technical fields, more particularly to a kind of with the meltable of conduction copper frame
Plug.
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 better band of overheating protection effect is provided and is led
The fusible plug of hot copper frame.
What the purpose of this utility model was realized in：
A kind of fusible plug with conduction copper frame, including cock body, the cock body is interior to be equipped with axially extending bore, and the axially extending bore is
Threaded hole, the axially extending bore is interior to be equipped with conduction copper frame, and the conduction copper frame includes mandrel, and takes shape in the lid of mandrel one end
Cap, the block are located at the outside of cock body, and the outer end face of the cock body is equipped with groove, is threaded in groove, the block
Inner headed face be threaded with groove screw-thread fit, be arranged in the block it is several for molten metal by flowing hole and cock body
Axially extending bore is connected to, the gap filling fusible metal between the conduction copper frame and axially extending bore hole wall.
Preferably, the cock body of the fusible plug with conduction copper frame includes head and molding of the cross section in regular hexagon
Screw rod interconnecting piece in head one end.
Preferably, the head end face adjacent with screw rod interconnecting piece forms annular groove, and sealing ring is arranged in annular groove,
The sealing ring protrudes outside annular groove.
Preferably, one end end that the sealing ring protrudes outside annular groove is arc-shaped.
Preferably, along the axially extending heat conduction fin of mandrel there are four being set on the circumferential surface of the mandrel.
Preferably, the flowing hole is sector, and each flowing hole is located between adjacent heat conduction fin.
Preferably, the end of the mandrel is located within axially extending bore.
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.

Fig. 2 is the structural schematic diagram of conduction copper frame；
Fig. 3 is the schematic side view of Fig. 2.
Reference numeral
In attached drawing, 1 is mandrel, and 2 be block, and 3 be flowing hole, and 4 be heat conduction fin, and 5 be groove；21 be head, and 22 be spiral shell
Bar interconnecting piece, 23 be sealing ring.
Specific implementation mode
Referring to Fig. 1-Fig. 3, a kind of fusible plug with conduction copper frame, including cock body, the cock body include that cross section is in positive six
The head of side shape and the screw rod interconnecting piece for taking shape in head one end.The head end face adjacent with screw rod interconnecting piece forms
Annular groove, annular groove is interior to be arranged sealing ring, and the sealing ring protrudes outside annular groove.The sealing ring protrudes one end outside annular groove
It holds arc-shaped.Axially extending bore is equipped in the cock body, the axially extending bore is threaded hole, and conduction copper is equipped in the axially extending bore
Frame.
The conduction copper frame includes mandrel, and takes shape in the block of mandrel one end, and the end of the mandrel is located at axially
Within through-hole.The block is located at the outside of cock body, and the outer end face of the cock body is equipped with groove, is threaded in groove, described
The inner headed face of block be threaded with groove screw-thread fit, sealing ring is set between block and groove slot bottom, is set in the block
Set it is several for molten metal by flowing hole be connected to the axially extending bore of cock body, set on the circumferential surface of the mandrel there are four along core
The axially extending heat conduction fin of axis.The flowing hole is sector, and four flowing holes are located between adjacent heat conduction fin.It is described
Gap filling fusible metal (not shown) between conduction copper frame and axially extending bore hole wall.The block of the conduction copper frame can also
It is set as regular hexagon, convenient for being loaded and unloaded by tool.
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.
