Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a power switch which is free from being rapidly installed by screws.

The technical purpose of the invention is realized by the following technical scheme: a power switch comprises a switch box body, a cover plate and a protective cover, wherein the cover plate is arranged on the switch box body, the protective cover is positioned outside the cover plate, a bulge is fixed on one end surface of the protective cover close to the cover plate, a through hole for the bulge to pass through is formed in the cover plate, a slot corresponding to the through hole is formed in the switch box body, a circumferential groove is formed in one end surface of the switch box body close to the cover plate along the circumferential direction of the slot and is communicated with the slot, a limiting sheet is fixed on one side of the circumferential groove close to the notch of the slot, a side surface of the limiting sheet far away from the notch of the slot and the side wall of the circumferential groove form a limiting area, an elastic clamp spring is arranged in the circumferential groove, the elastic clamp spring is waist-shaped and is provided with a notch, the arc-shaped edge of the elastic clamp spring is positioned in the limiting area, and two straight edges of the elastic clamp spring are positioned above the slot, the tip that the arch deviates from the safety cover forms arc guide part, an annular groove is seted up to the protruding lateral wall that is close to arc guide part, and arc guide part struts behind two straight flanges of elasticity jump ring continue to insert behind two straight flanges of elasticity jump ring and block in the annular groove.

The safety cover of this scheme makes two straight flanges of arch through arc guiding part strut the elasticity jump ring through pressing the safety cover, later continues to press and makes the arch get into the slot, because the elasticity jump ring has elasticity this moment, two straight flanges reset in the card goes into bellied ring channel to the restriction is protruding breaks away from in following the slot. In addition, the elastic clamp spring is limited in position through the limiting piece and the cover plate, and the elastic clamp spring is convenient to install or replace.

Furthermore, two limiting pieces are symmetrically arranged and respectively correspond to the two arc-shaped edges of the elastic clamp spring.

So, two arc edges are disperseed in the atress of elasticity jump ring, prolong the life of elasticity jump ring.

Furthermore, the notch corresponds to one of the limiting pieces and is positioned on the outer side of the limiting piece.

The breach sets up in spacing piece outside for because the restriction of spacing piece and circumference groove for the part of breach department is difficult for taking place excessive deformation and leads to the breach to be difficult to resume.

Furthermore, an accommodating groove for accommodating the cover plate is formed in the switch box body, a positioning piece is fixed on the side wall of the accommodating groove, the positioning piece is horizontally arranged and forms an interval with the bottom of the accommodating groove, the lower surface of the positioning piece is an inclined surface, and the inclined surface is inclined upwards from one end close to the bottom of the accommodating groove and is arranged outwards back to the side wall of the accommodating groove; the side wall of the cover plate is provided with a groove, a card is fixed in the groove, the upper end face of the card inclines downwards and extends outwards from the joint of the card and the cover plate, one end of the card, which deviates from the cover plate, is arranged at an interval with the side wall of the accommodating groove in the horizontal direction, and the upper surface of the card is abutted to the lower surface part of the positioning piece when the cover plate is positioned in the accommodating groove.

Through pressing the apron, force the spacer after the card cross the spacer entering holding tank, thereby later the spacer resets to being located the card top and spacing the apron, realizes the quick installation of apron. Because the whole of spacer and switch box body is made by plastics, consequently can take place deformation to a certain extent.

Furthermore, the switch box body is provided with an insertion hole communicated with the accommodating groove.

The cover plate can be conveniently pried out by inserting a opener and the like.

Furthermore, a vertical cover plate and a through groove which is communicated with the through groove are formed in the switch box body, the through groove is communicated with the accommodating groove, and the position of the through groove is opposite to that of the positioning sheet.

Because seting up of holding tank, can form the round on the switch box body and bordure, and the spacer is fixed on the lateral wall of borduring, leads to the groove setting and makes the restraint that the part of borduring that installs the spacer received still less to make the part of borduring of installing the spacer more easily with the spacer deformation expand outward together.

Furthermore, a buffer ring is fixed on the end face, facing the cover plate, of the protective cover.

The protective cover has certain buffering when pushing down.

Furthermore, the inside wall of safety cover and the lateral wall interval setting of switch box body.

The protective cover is convenient to take down from the switch box body.

Further, the switch box body includes the rocker switch, the outer terminal surface of rocker switch is fixed with the butt piece that extends to outside, and the butt piece symmetry sets up two, and two butt pieces are located the low side and the high-end of rocker switch respectively, the trompil that supplies the rocker switch to stretch out is seted up to the safety cover, the pore wall of trompil sets up with the outer wall interval of rocker switch, when being in of rocker switch opens or closes two kinds of states, one of them butt piece butt safety cover outer wall, when the outer terminal surface of rocker switch is in the horizontality, the butt piece sets up with the pore wall interval of trompil.

So, in the installation, the rocker switch is in the horizontality, and owing to the pore wall interval setting of butt piece and trompil this moment, the safety cover can be installed smoothly, and later the rocker switch is in normal open or closed state, always has the butt piece butt safety cover outer wall of one side, and the restriction safety cover drops.

Further, the cross section of the annular groove is semicircular.

Therefore, the semicircular arc-shaped edge has a certain guiding function, so that the straight edge can be conveniently separated from the annular groove, and the protective cover can be conveniently detached.

In conclusion, the invention has the following beneficial effects: the power switch is convenient to rapidly assemble and disassemble, and has a stable structure after being installed, so that the power switch is not easy to separate.
