Detailed description of the invention

Below in conjunction with accompanying drawing, a preferred embodiment of the present utility model is described in detail.Wherein identical parts represent with identical Reference numeral.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometric center.

As shown in Figure 1 or 2, what the utility model provided can comprise the air inlet pipe 2 and the blast pipe 3 that are fixed in tool heads 1 by heat exchange handle, exhaust outlet one end of described air inlet pipe 2 is fixedly connected in tool heads 1, air inlet one end of described blast pipe 3 is fixedly connected in tool heads 1, and the exhaust outlet of described air inlet pipe 2 is communicated with the air inlet of described blast pipe 3.Air inlet pipe 2 provided by the utility model and blast pipe 3 are preferably made up of steel pipe, steel pipe not only has enough support strengths, also be convenient to be welded to connect with the tool heads of bar kind irony, certainly, those skilled in the art can also adopt other known material to prepare described air inlet pipe 2 and blast pipe 3.

Tool heads 1 in the present embodiment preferably includes shovel, hook, pricker or fork.What those skilled in the art should understand that is, shovel, hook, pricker or fork are only a kind of preferred versions using as tool heads as the present embodiment, provided by the utility model can being also suitable for being fixed and being connected with other instrument known in those skilled in the art by heat exchange handle repeats no more herein.

When use, the exhaust outlet of the air inlet of described air inlet pipe 2 and blast pipe 3 is arranged on to the one end away from described tool heads, and will be communicated with near the exhaust outlet of air inlet pipe 2 and the air inlet of blast pipe 3 of described tool heads one end, thereby refrigerating gas is discharged through the exhaust outlet of described air inlet pipe 2, can enter the air inlet of described blast pipe 3, thereby make the cold air can described air inlet pipe and the interior circulation of described blast pipe 3, cold air is in the time of air inlet pipe 2 and the interior circulation of blast pipe 3, take away the heat on handle, realize the object that reduces handle temperature, and make handle temperature lower than softening temperature, and then instrument lower long-time needs that use under the hot environment are met, the normal use of guarantee instrument.

As a kind of preferred version of the present utility model, as shown in Figure 1, the air inlet of the exhaust outlet of described air inlet pipe 2 and described blast pipe 3 directly joins, and forms U-shaped pipe thereby described air inlet pipe 2 and described blast pipe 3 are communicated with.Described air inlet pipe 2 is fixed in described tool heads side by side with described blast pipe 3, and forms U-shaped connection at the exhaust outlet of described air inlet pipe 2 and air inlet one side of described blast pipe 3.

Particularly, as shown in Figure 1, the port at the top of described air inlet pipe 2 is air inlet, for being connected with source of the gas, the port at described blast pipe 3 tops is exhaust outlet, for discharging the air after heat exchange, the U-shaped connection of bottom port of the bottom port of described air inlet pipe 2 and described blast pipe 3, described air inlet pipe 2 and described blast pipe 3 form U-shaped pipe, and the bottom of described U-shaped pipe is fixedly mounted in described tool heads 1, complete the assembling of handle and tool heads.Cold air constantly enters from the air inlet of air inlet pipe 2, flows, and carry out heat exchange with tube wall within U-shaped communicating pipe, takes away the heat at tube wall place, the final emission by exhaust pipe from blast pipe 3.

As another kind of preferred version of the present utility model, as shown in Figure 2, described air inlet pipe 2 is set in the inside of described blast pipe 3, certainly, the caliber of described blast pipe 3 is greater than the caliber of described air inlet pipe 2, thereby between described air inlet pipe 2 and described blast pipe 3, is formed for the interlayer of gas flow.

When use, cold air source of the gas is communicated with the air inlet pipe 2 that is arranged on internal layer, the exhaust outlet of described air inlet pipe 2 bottoms is suspended at the bottom at described blast pipe 3, thereby make can enter the interlayer between described air inlet pipe 2 and blast pipe 3 after the cold air discharge in air inlet pipe 2, cold air is in described air inlet pipe 2 and the interior circulation of described blast pipe 3, carry out heat exchange with described air inlet pipe 2 and described blast pipe 3, thereby take away the heat on handle, realize the object that reduces handle temperature, and make handle temperature lower than softening temperature, and then instrument lower long-time needs that use under the hot environment are met, the normal use of guarantee instrument.

In order to make described air inlet pipe 2 more stably be fixed on described blast pipe 3 inside, between the outer wall of described air inlet pipe 2 and the inwall of described blast pipe 3, be also preferably provided with multiple locating dowels.More preferably, described locating dowel is welded between the outer wall of described air inlet pipe 2 and the inwall of described blast pipe 3, and described locating dowel preferably adopts thin round steel, and the materials such as bonding jumper are made.Described locating dowel the outer wall of described air inlet pipe 2 circumferentially, long to all there being distribution, thereby guarantee air inlet pipe 2 is inserted after described blast pipe 3, can form uniform and stable interlayer, also ensure that described air inlet pipe 2 leaves enough gaps in the bottom of described blast pipe 3, to facilitate gas flow simultaneously.

On the basis of above-described embodiment, the air inlet of described air inlet pipe 2 preferably stretches out described blast pipe 3, the air inlet of the air inlet pipe 2 of stretching out is conveniently communicated with cold air source of the gas, can also avoid simultaneously the hot-air that produces through heat exchange again mixed cold air enter air inlet pipe 2, thereby contribute to improve can heat exchange handle heat exchange efficiency.

Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these amendments or replacement do not make the essence of appropriate technical solution depart from the scope of the each embodiment technical scheme of the utility model.
