Background technology

Existing portable electric welding machine is not cover housing mostly, the iron core of its transformer and binding post all expose outside, the fail safe of using is low, do not reach the basic security standard of country, present for this reason many producers all with housing with Rack Body and transformer upper shield and envelope, consider that in use the magnetic field eddy current effect that produces because of energising owing to primary coil and secondary coil makes electric welding machine heating and produce the problem of vibrations greatly and noise easily, existing for this reason housing all is to adopt relatively more expensive low magnetization stainless steel to be made into bulky integral cap shell structure and to adopt big extraction fan with heat extraction, the raw material and the manufacturing cost of electric welding machine have been increased so on the one hand, on the other hand because its huge volume is given transportation and deposited makes troubles and increased cost of transportation.

Summary of the invention

The purpose of this utility model is the problem at above-mentioned existence, provides a kind of simple and ingenious structure, with low cost, transportation to deposit portable easily electric welding machine.

The technical solution of the utility model is achieved in that

A kind of portable electric welding machine, comprise Rack Body, transformer and some binding posts and connecting circuit, wherein transformer is made up of the primary coil and the secondary coil that are wound on respectively on the iron core, iron core is fixed on the Rack Body, but it is characterized in that also including the housing that upper shield envelopes Rack Body and transformer, wherein this housing is made up of the some veneers that directly post respectively and be fixed on the Rack Body.

Wherein for effectively reaching national safety standard, above-mentioned right plate top have can ccontaining lead-in clamp breach, this breach loam cake is equipped with removable arcuation room female cap plate.Above-mentioned output wiring terminal is fixed on the Rack Body leading flank by a terminal block, and the position of corresponding output wiring terminal is covered removably to be equipped with and is the L shaped side cover plate of falling of evagination on this leading flank.

The utility model posts the structure that constitutes housing on Rack Body owing to adopting by a plurality of veneers dexterously, make the utility model can reach on the basis of national security production standard reliably, effectively reduce raw material of the present utility model and production cost again, particularly can use up maximum ground and reduce its volume that takies, transportation is deposited conveniently, cost is low, make product have stronger market competition advantage, and avoided the desired Mold Making cost of the big housing of the formula of being made into one height again, the problem that difficulty is big, and the utility model is simple in structure, make easily, practical.

Describe basic structure of the present utility model in detail below in conjunction with accompanying drawing:

Fig. 1 is a decomposition texture schematic diagram of the present utility model.

Embodiment

As Fig. 2～shown in Figure 4, the utility model comprises Rack Body 1, transformer 3 and some binding posts 4 and connecting circuit, wherein transformer 3 is made up of the primary coil 31 and the secondary coil 32 that are wound on respectively on the iron core 33, iron core 33 is fixed on the Rack Body 1, but be characterized in also including the housing 2 that upper shield envelopes Rack Body 1 and transformer 3, wherein this housing 2 is made up of the some veneers that directly post respectively and be fixed on the Rack Body 1.Wherein for ease of making, simplify production technology, above-mentioned housing 2 is by posting left and

right side plate

21,25 at Rack Body 1 left and right sides face, post base plate 22 and top board 23 in Rack Body 1 end face and bottom surface, posting at the back plate 24 of Rack Body 1 trailing flank and form, and wherein a side of base plate 22 and top board 23 or its both sides bend inwards to form flap and post on the leading flank of Rack Body 1 or front and back sides and form the front or rear panel parts.For helping heat radiation, make it can keep reliably that a good ventilated environment is arranged in the electric welding machine, have some bar shaped ventilation windows 221 on above-mentioned base plate 22 and the flap thereof, aerofoil fan 5 is equipped with in plate 24 inboards, above-mentioned back, and the position of respective shaft flow fan 5 has some trellis thermal windows on this back plate 24.Be bent to form room shape top board under above-mentioned top board 23 both sides are oblique, have some ventilating openings 231 on this top board with cover.For further making the utility model can reach safety standard reliably, above-mentioned right plate 25 tops have can ccontaining lead-in clamp 4 breach 251, these breach 251 loam cakes are equipped with removable arcuation room female cap plate 252.Above-mentioned left plate 21 is provided with current regulating switch and the power supply indicator (not drawing among the figure) that is communicated with transformer 3.Above-mentioned output wiring terminal 4 is fixed on Rack Body 1 leading flank by a terminal block, and the position of corresponding output wiring terminal 4 is covered removably to be equipped with and is the L shaped side cover plate 41 of falling of evagination on this leading flank.The description of materials of above-mentioned each veneer can be varied simultaneously, can be to adopt the quite cheap expensive relatively corrosion resistant plate of iron plate, plastic plate, aluminium sheet, galvanized sheet or price of price, and owing to be to adopt to form housing by a plurality of veneers, thereby it can adopt trifling relatively corner panel material to make, significantly to reduce material cost.The big problem of heating height, vibrations and noise that the magnetic field eddy current effect that produces because of coil electricity for effective solution transformer 3 causes, as shown in the figure, above-mentioned primary coil 31 is made up of the two parts that are wound on iron core 33 upper and lower frame post one sides respectively, and above-mentioned secondary coil 32 is composed in series by the two parts that are wound on iron core 33 upper and lower frame opposite sides respectively.The structure that is wound on iron core and arranged on left and right sides of lateral column about in the of 33 respectively by primary coil 31 and secondary coil 32 like this with transformer 3, coil is greatly weakened because of the magnetic field eddy current effect that energising produces, thereby effectively reduce heat generation rate and the vibrations and the noise of transformer.Being simplified structure simultaneously, reducing the difficulty that coil twines, when adopting plastic cement, aluminium or the corrosion resistant plate of non-magnetic conduction to make and arranged on left and

right sides plate

21,25, also can be that above-mentioned primary coil 31 and secondary coil 32 are wound on respectively on the iron core 33 upper and lower frame posts.
