Detailed description of the invention
Whether high pressure three-phase electrical verification lock of the present utility model is arranged on the cabinet outer side of door of switchboard, charged for detection of the three-phase line in switchboard.
Referring to Fig. 3, high pressure three-phase electrical verification lock 30 of the present utility model has cover 31 and base 50, and base 50 is arranged on cabinet door 48 outsides of switchboard.Base 50 can be fixed on cabinet door 48 by screw, rivet etc., also can be bonded on cabinet door 48.
Cover 31 is fastened on base 50, the lower end of cover 31 is provided with cable-through hole 43, and electric wire 44 is through cable-through hole 43, and electric wire 44 is connected with multiple electric connection terminals 45, each electric connection terminal 45 is connected to one of three-phase line and goes up mutually, and gathers voltage signal or the current signal of three-phase line.Cover 31 surrounds a cavity with base 50, in cavity, be provided with electric signal processing circuit, electric signal processing circuit is electrically connected with electric connection terminal 45, and the signal that electric connection terminal 45 is gathered is processed, whether as will be low-voltage AC by High Level AC Voltage, and it be charged to calculate three-phase line.
Referring to Fig. 4 and Fig. 5, cover 31 is roughly cuboid, and its bottom is uncovered, i.e. a side opening of close base 50.The front of cover 31 is provided with lockhole 40, is provided with contact electrode 41 in lockhole 40.In the present embodiment, contact electrode 41 is reed.Use electrical verification to lock at 30 o'clock, the locking bar of Intelligent key can be inserted in lockhole 32, and the contact electrode of Intelligent key is electrically connected with the contact electrode 41 in lockhole 40.Contact electrode 41 is also electrically connected with the electric signal processing circuit in electrical verification lock 30.
Cover 31 is provided with multiple LED light 42, is used to indicate the charged state of three-phase line, as charged in a certain phase circuit, and the indicator lamp 42 of corresponding phase is luminous or luminous with CF flash, sends thus information warning.
Cover 31 has the sidewall 32,35 of pair of opposing, and sidewall 32 is provided with two through holes 33,34, and each through hole 33,34 all runs through sidewall 32.On sidewall 35, be also provided with two through holes 36,37, and two through holes 36,37 all run through sidewall 35.In the present embodiment, multiple through holes 33,34,36,37 form snap close piece, for cover 31 is fastened to base 50.When practical application, snap close piece can also be arranged on the groove on sidewall 32,35 inner surfaces, and this groove to sidewall 32,35 inner recess, does not namely run through sidewall 32,35 from the inner surface of sidewall 32,35.
Base 50 is fixed on cabinet outer side of door, referring to Fig. 6, base 50 is roughly rectangle, and it has base plate 51 and is arranged on the upper cover 63 on base plate 51, base plate 51 is fixed on the outside of cabinet door 48 by screw, rivet or the mode such as bonding, upper cover 63 is also fixed on base plate 51 with base plate 51 interference fit.
Referring to Fig. 7 and Fig. 8, base plate 51 is plate body, and base plate 51 surrounds a cavity with upper cover 63, is provided with 53, two lock buckling strips 53 of two lock buckling strips and is separately positioned on the both sides near base 50 in cavity.On each lock buckling strip 53, be respectively equipped with two locking-bars 54, two locking-bars 54 on each lock buckling strip 53 are positioned at the two ends of lock buckling strip 53.As seen from Figure 6, two locking-bars 54 are positioned at the two ends of base plate 51 length directions.
Locking-bar 54 is fixed on lock buckling strip 53, and self-locking profile 53 upwards extends towards the surface of upper cover 63, one end that locking-bar 54 is fixed on lock buckling strip 53 is fixed end, and one end relative with fixed end is free end 55, and therefore free end 55 is positioned at the upper end of locking-bar 54.Free end 55 is provided with buckling parts 56, and buckling parts 56 is provided with an inclined-plane 57 tilting with the upper surface of base 50.
Upper cover 63 is provided with four through holes 66 that run through upper cover 63 upper and lower surfaces, the position of four through holes 66 is corresponding with four locking-bars 54 respectively, as seen from Figure 6, the free end 55 of each root locking-bar 54 is all through a through hole 66 and extend to the side of through hole 66 near cover 31.In the time that cover 31 is installed to base 50, the buckling parts 56 of locking-bar 53 fastens in the snap close piece of cover 31, namely fastens in through hole 33,34,36,37, thereby cover 31 is fixed on base 50.
One side of each lock buckling strip 53 is equipped with a projection 58, and projection 58 is arranged on the side near upper cover 63 sidewalls.And, on two sidewalls 64 of upper cover 63, being equipped with a groove 67, the outer end of projection 58 is passed groove 67 and is extended to outside sidewall 64, and namely projection 58 passes the sidewall 64 of upper cover 63.Like this, people drive lock buckling strip 54 in the interior slip of base 50 by pressing projection 58, thereby drive locking-bar 54 to slide.
Certainly, the quantity of the projection 58 of each lock buckling strip 53 outer setting can be above one, can be also two or more, and projection 58 shapes also can change according to actual needs.In the present embodiment, the outward flange of projection 58 is positioned at the outer peripheral outside of base plate 51, and namely projection 58 has stretched out beyond base plate 51, and user can press projection 58 easily.When practical application, the outward flange of projection 58 can be to be positioned at the outer peripheral inner side of base plate 51, like this, cover 31 is installed is and need to use instrument auxiliary projection 58 be pressed.
In order to realize the reset of lock buckling strip 53, in base 50, be provided with four springs 60, in each lock buckling strip 53, be provided with spring eye 59.Referring to Fig. 9 and Figure 10, in upper cover 63, be provided with butt piece 68, butt piece 68 is positioned at a side of lock buckling strip 53, and one end of spring 60 is connected on butt piece 68.Therefore, spring 60 is between butt piece 68 and lock buckling strip 53, and the two ends of spring 60 are connected to respectively on butt piece 68 and lock buckling strip 53, thereby provides elastic restoring force for lock buckling strip 53.When actual use, can use other elastic component, as alternative springs such as shell fragments.
When cover 31 is installed to base 50, the projection 58 of first pressing two lock buckling strip 53 outsides makes two lock buckling strips 53 all to base 50 inner slide, thereby drives four locking-bars 54 to base 50 inner slide.Then, cover 31 is placed on base 50, unclamps projection 58, the buckling parts 56 of locking-bar 54 will fasten in through hole 33,34,36,37, thus by fixing cover 31.When cover 31 is dismantled, be also to press projection 58, the buckling parts 56 of locking-bar 54 is threaded off from through hole 33,34,36,37, can easily cover 31 be dismantled.
Visible, high pressure three-phase electrical verification lock construction of the present utility model is simple, and the installation of cover 31, disassembling section are also very simple, and can not damage locking-bar 54, and electrical verification lock can use for a long time.
When practical application, the locking-bar that is positioned at base 50 1 sides can be base plate 51 or the upper cover 63 that is fixed on base 50, is not arranged on lock buckling strip 53.Like this, a part of locking-bar 54 of base 50 is fixed with respect to base 50, and another part locking-bar 54 can slide with respect to base 50, also can avoid the damage of locking-bar 54.
Certainly, above-described embodiment is only a preferred scheme of the present utility model, when practical application, can also there is more variation, for example, the quantity of locking-bar can be set to two, be the both sides that pair of catches bar is separately positioned on base, and each root locking-bar fasten to respectively in the snap close piece in sidewall of cover; Or the butt piece in base is arranged on base plate instead of in upper cover, such change also can realize the purpose of this utility model.
The variations such as the change of the change of locking-bar shape, locking-bar fixed form finally it is emphasized that the utility model is not limited to above-mentioned embodiment, as also should being included in the protection domain of the utility model claim.
