Abstract

The utility model relates to an interlocked hole sealing type safety power-supply socket. Two interlocked type sliding rods are arranged at a plug-hole opening. Under the action of a spring, generally a plug hole is sealed. When a plug is plugged in, the plug can push the sliding rods to enter the plug hole. Because the two sliding rods are mutually interlocked, and are engaged with fixing stop blocks by a self-locking plate, as long as the sliding rods are simultaneously pushed, a lock hole can be opened. Therefore, foreign matters can not be poked into the socket. In addition, a locking mechanism is arranged at the moving part of the self-locking plate. When the socket is not used, the self-locking plate can be locked, and the plug hole is not no longer opened. Compared with the existing sockets, the utility model has characteristic of safety, and has the characteristics that the plug hole is sealed, and the socket can be locked.

Description

Safety electric outlet

The utility model relates to a kind of supply socket, particularly a kind of safety power source plug socket that has the mutual-locked and hole-sealed type device.

Existing supply socket, eyelet is open state, as child's naughtiness, discloses jack at the moment with finger or Metallic rod etc., occurs dangerous easily.Even have the supply socket of pulling switch, also fail to address this problem well.

The purpose of this utility model is that a kind of safety power source plug socket will be provided, and can make non-attaching plug can't insert eyelet, can carry out locking to socket again, thereby remedies the defective of existing socket well.

The utility model is achieved in that the inclined-plane slide bar that two interlocking-types are arranged at the jack mouth, and an end of slide bar stretches in the hole of socket base plate, can do transverse movement, under spring action, the slide bar inclined-plane covers jack at ordinary times, when attaching plug inserts, can promote the slide bar inclined-plane, enter in the hole.Because two Slide bar structures in two holes are interlocked each other about placing, self-locking plate rightly with fixedly stop block interlock, two block self locking plates have only action simultaneously just to understand to separate with stop block, therefore, when having only a hole to disclose into foreign matter, be to promote the slide bar inclined-plane, enter in the socket.Moreover, move the place at self-locking plate, settled a locking projection, socket is the time spent not, the locking projection can be turned to 90 °, withstands self-locking plate, and jack is promptly no longer opened.

The utility model has three tangible characteristics than existing socket: one, safe and reliable, foreign matter can't insert; Two, jack sealing has certain effects such as waterproof and dustproof; But three, socket locking, the time spent can not prevent accident.So renewal product of the existing power supply socket of can yet be regarded as.

Be further described below below in conjunction with accompanying drawing.

Fig. 1 is mechanical control principle figure of the present utility model.

Fig. 2 is the A-A profile of Fig. 1.

The utility model is made up of following part: base plate 1, the two pairs of

torsion springs

2,18,

push pedal

3,19,

stabiliser bar

4,20, self-

locking plate

5,21, slide bar inclined-

plane

6,11,

jack

7,22,

stop block

8,23,

attachment screw

9,16, self-

locking board slot

10,24, push pedal inclined-

plane

12,26, self-

locking plate bulb

13,28, back-moving

spring

14,29,

slide bar

15,30, fixed

head

17,31, stability column 25, tapered end 32, lock core 33.

As shown in the figure, 17,31 all become two and occur from two pairs of

springs

2,18 to fixed head, and its operation principle, operate condition are just the same, just the present position difference.Wherein shown in

stop block

8,23, fixed

head

17,31 and the stability column 25(hatching) all be fixed on the base plate 1 motionless.And push pedal 19, stabiliser bar 20, slide bar 15 fuse, and back-moving spring 14 is enclosed within slide bar 15 outsides, when no plug inserts, slide bar inclined-plane 11 is resetted cover jack 22.Slide bar 15 1 ends insert in fixed head 17 holes, and stabiliser bar 20 inserts in stability column 25 holes, and slide bar 15 and stabiliser bar 20 1 are to play the stabilizing means effect, and the 2nd, can do transverse movement with push pedal 19.Flexibly connect with attachment screw 16 between push pedal 19 and the self-locking plate 21, torsion spring 18 makes and keeps plumbness between it.Self-locking board slot 24 keeps certain interval and interlock highly with stop block 23.In like manner, another set of functions of components too.

When no plug, slide bar inclined-

plane

6,11

covers jack

7,22, just is in non operating state as shown in Figure 1.When plug inserts, promote slide bar inclined-

plane

6,11, the

slide bar

15,30 of ining succession moves slightly to both sides, drives

push pedal

3,19 simultaneously and moves together, and self-

locking plate bulb

13,28 is under the effect on push pedal inclined-

plane

12,26, self-

locking plate

5,21 is lifted, while under the tension of another

push pedal

3,19, makes its self-

locking board slot

10,24 walk around

stop block

8,23 again, makes

slide bar

15,30 be pushed into

fixed head

17,31 both sides fully eventually, slide bar inclined-

plane

6,11 no longer covers

jack

7,22, and plug inserts.In the time of in foreign matter attempt patchhole, situation is just different, is being with push pedal 19 to move right slightly as slide bar 15, and self-locking plate 5 is lifted slightly.But push pedal 19 can't spur self-locking plate 21 and do to move to right more greatly.Because self-locking plate 21 must be lifted, self-locking board slot 24 could be moved to right by push pedal 19 pullings after getting around stop block 23.Yet moving to left of push pedal 3 depended in lifting of self-locking plate 21, and push pedal 3 can not move to left under the effect that does not have external force (promptly not having plug).Push pedal 3 motionless makes self-locking plate 21 also motionless.This has just determined that it is to do the bigger activity that moves to right that the push pedal 19 of attachment screw 16 relations is arranged with it.So just stoped being open of slide bar inclined-plane 11, got rid of foreign matter and inserted possibility.When socket time spent not, can make 90 ° of tapered end 32 deflections by lockhole 33, stop push pedal 3 activities, socket promptly is in blocking.Socket shown in Figure 1 locking.All can in arbitrary outer that tapered end 32 is installed in

push pedal

3 or 19.

Base plate 1, fixed

head

17,31, stability column 25 adopt insulating material such as plastics, bakelite as far as possible.The gap of self-

locking board slot

10,24 and

stop block

8,23, height are good shown in scheming.
