The partial schematic sectional view that Fig. 5 finishes for the utility model combination;

Fig. 5 A is a part section enlarged drawing of the present utility model;

Fig. 6 is the schematic perspective view of the utility model assembling base.

At first please join the Blast burner frame of the utility model shown in Fig. 1 to 4, it comprises:

Fuel cartridge 2 is the liquefaction gas jar of the general requirements of being sold on the market, holds the top horizontal plane of the can 21 of semicircular in shape to be provided with suitable big nahlock body 211 thereon, and these nahlock body 211 peripheries are because of producing gap 212 with can 21 driving fits;

Location lid 3, be a shape, medial surface is concaved with an annular groove 33 by lower end, location lid 3 all sides have been horizontally set with slotted hole 34 by curved arc handle 4 places, and slotted hole 34 is communicated with

annular groove

33,4 appropriate locations of slotted hole 34 and curved arc handle of location lid 3 all sides also are equipped with the aperture 35 that communicates with annular groove 33;

Base 6 is formed with boss body 61 at appropriate location, and these boss body 61 section centers are formed with the round recessed 611 of slightly larger in diameter in fuel cartridge 2, is being provided with the little convex body 62 that a section center has the little groove 621 of the lighter of can planting near boss body 61 appropriate locations;

Iron ring 7, for circular, and slightly flexible, the one end be bent to form slightly be triangular shape pull the section of pushing away 71, another end then is formed with bending segment 72;

See also shown in Figure 2, this Blast burner frame is the curved arc handle 4 of plat part 41 and locatees lid 3 in the intrinsic upper end of spiral shell successively by connector 51 lower ends of nozzle 5, this iron ring 7 is seated in the annular groove 33 of lid 3 inboards, location, and the section of pushing away 71 of pulling of iron ring 7 appears outside the slotted hole 34 of locating lid 3, the bending segment 72 of iron ring 7 then is placed through in the aperture 35 fixing, this moment, iron ring 7 was owing to be slightly less than the diameter of annular groove 33, so can't sink in the annular groove 33, the section of pushing away 71 of pulling of iron ring 7 is pulled and shifted the end onto, iron ring 7 is tightly supportted in the annular groove 33 of location lid 3, as shown in Figure 2, can be nested with location lid 3 nahlock body 211 places of can 21 above fuel cartridge 2 this moment, just can remove forcing in the pressure of pulling the section of pushing away 71, then the section of pushing away 71 of pulling of iron ring 7 returns to original position, and iron ring 7 also returns to the state less than annular groove 33, as shown in Figure 3, location lid 3 can be fastened in the gap 212 of nahlock body 211 belows of can 21 of fuel cartridge 2, can not produce the situations that location lid 3 and fuel cartridge 2 break away from mutually; Connect fuel cartridge 2 backs when on the shelf at Blast burner frame, the bottom of fuel cartridge 2 can be inserted in the round recessed 611, as shown in Figure 4.

When desiring in conjunction with location lid 3 and Blast burner frame, what only need the application of force to pull gently to push away iron ring 7 pulls the section of pushing away 71, the nahlock body 211 of the can 21 of fuel cartridge 2 can be packed in the lid 3 of location, and make iron ring 7 cards be limited to the gap 212 of nahlock body 211 belows, conformability after both combinations is very good, and easier, laborsaving when mounting or dismounting; Iron ring 7 arrest be formed on fuel cartridge 2 and permanent the use after, can be because of flexible disappearance makes location lid 3 and fuel cartridge 2 not driving fits, locate lid 3 and prevent gas leakage so can prevent that fuel cartridge 2 does not break away from for no reason.

Another kind of embodiment such as Fig. 5 of the utility model Blast burner frame, 5A, shown in 6, connector 51 lower ends of this nozzle 5 intrinsic upper end of spiral shell successively are the curved arc handle 4 of plat part 41 and the location lid 3 that is a shape, wherein, this location lid 3 vertically cuts open in equidistant appropriate location and is provided with several rectangular grooves 32, lower end appropriate location between the per two rectangular grooves 32 is concaved with small salient point 31, and the front end of the can 21 of general on the market liquefaction gas jar 2 upper end semicirculars in shape of selling convexes with suitable big nahlock body 211, these nahlock body 211 circumference ora terminalis are provided with lead angle, can be for the 3 convenient assemblings of location lid, these nahlock body 211 peripheries are because of producing gap 212 with can 21 driving fits, put nahlock body 211 with having the made location lid 3 tight support sets of metal material of rigidity slightly at the can 21 of fuel cartridge 2, because location lid 3 can produce elasticity for metal material, and being provided with rectangular groove 32 can be for supporting, so can be behind nahlock body 211 at location lid 3 support sets, the rectangular groove 32 of location lid 3 promptly can restore to the original state, make small salient point 31 embeddings of locating lid 3 be formed on the gap 212 of nahlock body 211 belows of can 21, shown in Fig. 5 A, and can not produce the situations that location lid 3 and fuel cartridge 2 break away from mutually, and, can make fuel cartridge 2 break away from location lids 3 if fuel cartridge 2 is pulled about gently; Be formed with boss body 61 in base 6 appropriate locations, these boss body 61 section centers are formed with the round recessed 611 of slightly larger in diameter in fuel cartridge 2, again in be formed with a suitable high little convex body 62 near boss body 61 appropriate locations, the section center of this little convex body 62 is formed with the little groove 621 of the lighter of can planting, connect fuel cartridge 2 backs when on the shelf at Blast burner frame, the bottom of fuel cartridge 2 can be inserted in the round recessed 611, as shown in Figure 6.

Conformability after this is located lid 3 and fuel cartridge 2 combines is very good, and when fuel cartridge 2 is desired to be loaded on Blast burner frame, only need location lid 3 tight support sets are placed the nahlock body 211 of the can 21 of fuel cartridge 2, and make small salient point 31 be equipped in the gap 212 of nahlock body 211 belows, can make both firm combinations, and it is very easy, laborsaving, this fuel cartridge 2 is in conjunction with behind the Blast burner frame, base 6 can be separated with Blast burner frame during use, only with hand is held curved arc handle 4 and can be used, this moment is if there is long work of the time of holding high to do, can not remake into the situation that hand acid often need put down one's hand and have a rest because of matter yet, and,, also be convenient to hold simultaneously so flexibility ratio is higher when using because of weight is lighter, after hours, the bottom of fuel cartridge 2 can be inserted in the round recessed 611 of base 6, and Blast burner frame is increased together with the area of fuel cartridge 2 kiss the earths, increases Blast burner frame and fuel cartridge 2 and places ground steadiness.
