Abstract
The utility model relates to a welding gun, in particular to a hot air welding gun used for welding plastics. The welding gun adopts the technical scheme that the hot air welding gun comprises a gun body, a heating tube, a blower, an air outlet and switch power cable components, and is characterized in that an installation part with a spiral air duct is arranged between the blower and the heating tube. By virtue of the scheme, the utility model overcomes the shortcomings of the prior art, and provides the novel hot air welding gun, which has swirling air blown out of the gunpoint and greatly increases the utilization ratio of the blower.
Description
Technical field
The welding gun of the utility model design welding usefulness is meant to be used for the hot blast welding gun that welding plastic is used especially.
Background technology
Existing hot blast welding gun, it includes rifle body, heating tube, blower fan, air outlet and Switching Power Supply line component, its blower fan carries out work with regard to directly aiming at heating tube, there is following problem in such structure: the wind that 1, comes out is form of straight lines, so in case the muzzle of welding gun has distortion or is stopped up by object, the hot blast intensity of coming out from welding gun just reduces like this, does not reach requirement, has a strong impact on work; 2, the blower fan of welding gun is mounted in a side that is positioned at the rifle head of motor, and this structure is in fan operation, and the air intake of air inlet is blocked by motor, so also influence the operating efficiency of blower fan.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and it is the eddy flow wind direction that a kind of wind that muzzle is blown out is provided, and improves the novel hot blast welding gun of blower fan utilization rate greatly.
In order to realize above purpose, the utility model is by the following technical solutions: a kind of hot blast welding gun, include rifle body, heating tube, blower fan, air outlet and Switching Power Supply line component, it is characterized in that: the installed part that is provided with the band spiral duct between described blower fan and the heating tube.
By adopting such scheme, the wind that the air outlet of hot gas welding rifle is come out have spiral wind to, efficiently solve like this hot blast welding gun muzzle distortion arranged or stopped up by object, the hot blast intensity of coming out from welding gun just reduces like this, does not reach the shortcoming of requirement.
Further setting of the present utility model is: described blower fan includes motor and fan blade, fan blade is positioned at close rifle body tail end one side of motor, be provided with the working of plastics of band spiral duct between fan blade and the motor, the spiral duct of this working of plastics is identical with the direction of the spiral duct of installed part, leave the air channel of air feed circulation between the inner walls of described motor and rifle body, the air channel between the inner walls of the spiral duct of described working of plastics, motor and rifle body and the spiral duct of installed part constitute the passage of wind formation eddy flow wind direction in the rifle body.
By adopting such scheme, can make the better effects if of wind direction eddy flow, fan blade adopts the aforesaid way setting in addition, can improve its operating efficiency, in the utility model, we also can not be provided with the working of plastics of band spiral duct, and only the installed part by the band spiral duct changes wind direction, single such effect relatively can be poor, so do not adopt.
Further setting of the present utility model is: described installed part is whole to become reducing shape, and the hand of spiral is provided with the polylith block on its inwall, and the groove between block and the block constitutes the above spiral duct of installed part; Described working of plastics is provided with grab, and working of plastics is arranged on by grab on the motor of blower fan, and the fan blade of described blower fan is outside equipped with case, and described working of plastics also places in the case.
By adopting such scheme, make this product reasonable integral structure, easy for installation.
Below in conjunction with accompanying drawing the utility model is described in further detail
Description of drawings
Fig. 1 is the utility model example structure schematic diagram;
Fig. 2 is the explosive view of Fig. 1;
Fig. 3 is the structural representation of the working of plastics of the band spiral duct among Fig. 1;
Fig. 4 is the structural representation of the installed part of the band spiral duct among Fig. 1.
The specific embodiment
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of hot blast welding gun includes rifle body 1, heating tube 2, blower fan 3, air outlet and Switching Power Supply line component, is provided with the installed part 4 of band spiral duct between described blower fan 3 and the heating tube 2.Described blower fan 3 includes motor 31 and fan blade 32, fan blade 32 is positioned at close rifle body 1 tail end 11 1 sides of motor 31, fan blade 32 adopts the aforesaid way setting, can improve its operating efficiency, be provided with the working of plastics 5 of band spiral duct 51 between fan blade 32 and the motor 32, the spiral duct 51 of this working of plastics 5 is identical with the direction of the spiral duct 41 of installed part 4, is noted that here working of plastics 5 also can be that the metal manufacturing forms; In the utility model, we also can not be provided with the working of plastics 5 of band spiral duct 51, and only the installed part 4 by band spiral duct 41 changes wind direction, but such effect relatively can be poor, so do not adopt.Leave the air channel 6 of air feed circulation between the inner walls of described motor 31 and rifle body 1, air channel 6 between the inner walls of the spiral duct 54 of described working of plastics 5, motor 31 and rifle body 1 and the spiral duct of installed part 4 41 constitute the passage of wind formation eddy flow wind direction in the rifle body 1.Described installed part 4 is whole to become reducing shapes, and the hand of spiral is provided with polylith block 42 on its inwall, the above spiral duct 41 of groove formation installed part between block 42 and the block 42 4; Described working of plastics 5 is provided with grab 52, and working of plastics 5 is arranged on by grab 52 on the motor 31 of blower fan 3, and the fan blade 32 of described blower fan 3 is outside equipped with case 321, and described working of plastics 5 also places in the case 321.By adopting such scheme, make this product reasonable integral structure, easy for installation.
