Description

The adjustable transformer device structure

The utility model relates to a kind of adjustable transformer device structure.

Locate in various operation occasions such as electric welding, welding, laboratory, electrical maintenance etc., often must use various voltage with in the input machine as power supply or signal source.Yet it all adopts fixed value for providing of output voltage the general transformer that provides, and perhaps only is some kinds of limited output voltage values.Demand regular meeting for voltage in actual the use changes, and therefore general transformer can't be widely used.

The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of structure that the input high pressure can be tuned as various different low pressure outputs that has is provided.

For achieving the above object, the utility model provides a kind of adjustable transformer device structure, mainly be at the board base with suitable folder apart from having extended forward and backward seat sheet, stator and back stator before this front stall sheet and back seat sheet opposite face are fixed with respectively.String is adorned a winding assembly that includes some coil windings between this forward and backward stator, is provided with the adjuster structure on the board base of one side, is characterized in:

This adjuster structure-steel framing is provided with upper and lower two parallel conductive screw rods, its front end wear frame in preceding stator and end wear be butted on the back stator, the proximal end of two driving screws respectively is connected in series a gear and links with chain, the front end of driving screw is received a rocking bar on this again, and wears a ring cowling packing ring and a buffer spring at the end of each screw rod.The common serial connection one of this upper and lower driving screw is adjusted seat, is connected in series with the upper and lower driving screw of inner bolt hole and this.

A Qian body has respectively been received in the coil windings position that this adjustment seat is gone up corresponding aforementioned winding assembly, then can be spirally connected one L shaped at its opening part, side in this Qian body then is fixed with catch, loads some contact blocks in the space that is surrounded, and is folded with spring between these contact blocks and the catch; This each contact block all correspondence is contacted with aforementioned coil windings place, simultaneously each contact block all has lead to be connected to L shaped to locate, each L shaped rectifier place that all is connected to the board base with lead, also be connected to rectifier with lead from each coil windings, self-rectifying device place then has an output lead to be connected to output on the board panel.

The utility model has the advantages that: (1) is simple in structure, and is easy to install and use; (2) because the structure of adjuster, but modulation input high pressure is various low pressure output, therefore can be widely used in various operation occasions.

Now for enabling, sincerely cooperate graphic giving again further to specify in the back to structural design of the present utility model and technology:

Fig. 1 is an internal structure schematic diagram of the present utility model.

Fig. 2 is an adjuster member decomposing schematic representation of the present utility model.

Fig. 3 is stereoscopic figure of the present utility model.

Fig. 4 is a structural plan of the present utility model end view.

Fig. 5 is a structural plan of the present utility model vertical view.

See also Fig. 1, the utility model mainly is before board base 11 has extended with suitable folder distance on structural design, back seat sheet 13,14 (with reference to Fig. 4), stator 15 and back stator 16 before this front stall sheet 13 and back seat sheet 14 opposite faces are fixed with respectively, before this, back stator 15, string is adorned a winding assembly 2 that includes some coil windings 21 between 16, on the board base 11 of one side, be provided with adjuster 3 structures, see also Fig. 2, it has set up, following two

parallel driving screws

31,32, its front end wear frame in preceding stator 15 and end wear be butted on the back stator 16, two driving

screws

31,32 front end place respectively is connected in series a gear 311,321 and with chain 33 link with turn synchronously, the front end of driving screw 31 is received a rocking bar 34 on this again, and at each

screw rod

31,32 end wears a ring cowling packing ring 312,322 and one buffer spring 313,323; Adjust seat 35 in these upper and

lower driving screw

31,32 common serial connections one, it is to make with the ceramic material of insulation, because of it is connected in series with aforementioned upper and

lower driving screw

31,32 with inner bolt hole, so this adjustment seat 35 will advance or retreats with the turn direction when this upper and lower driving screw of

turn

31,32.

Hold above, a Qian body 36 has respectively been received in coil windings 21 positions of corresponding aforementioned winding assembly 2 on this adjustment seat 35, then can be spirally connected one L shaped 37 at its opening part, side in this Qian body 36 then is fixed with catch 38, in the space that is surrounded, can load some contact blocks 39, and be folded with spring 391 between these contact blocks 39 and the catch 38, so make this contact block 39 have suitable elasticity; This each contact block 39 all correspondence is contacted with aforementioned coil windings 21 places, and each contact block 39 all has lead to be connected to L shaped 37 place simultaneously; In addition, each L shaped 37 all is connected to rectifier 4 places on the board base 11 with lead, then is provided with radiator fan 5 at rectifier 4 rears; Each coil windings 21 also is connected to rectifier 4 places with lead again, and self-rectifying device 4 places then have an output lead 6 to be connected to output 101 on the board panel 10.

Fig. 3 is stereoscopic figure of the present utility model, is to have added board loam cake 12.

Fig. 4 and Fig. 5 then are structural plan of the present utility model side-looking and vertical view, and it has clearly described the annexation between each parts.

Therefore, input high voltage such as 220V or 380V all can when using, adjust seat 35 advance and retreat to control the contact position of its contact block 39 and coil windings 21 via the aforementioned rocking bar 34 of turn to move, owing to will influence the size of output voltage from the contained coil windings 21 that reaches of ground termination contact block 39 contacts according to electrical principles, be contained and coil windings 21 numbers of turn the more, then the voltage of being exported is higher, the voltage that the number of turn is exported more at least is lower, therefore, by this kind mode, can use in order to stepless adjustment output voltage, it serves to show progressive effect of the present utility model.
