Abstract

A socket with a safe door is additionally provided with a jack safe door between an upper housing and a lower housing of the socket; under the function of the plug and the pin, the safe door can be automatically and rotatablely opened by means of a cone in the front end of the safe door, or the safe door can automatically rotate and close the jack of the socket. The safe door has the advantages of simple structure, flexible and convenient use and is suitable for manufacturing various forms of sockets.

Description

A kind of socket that has emergency exit

Affiliated technical field

The utility model relates to a kind of supply socket, especially a kind of socket that has emergency exit.

Background technology

At present, known supply socket, for preventing Danger Electric shock risk to take place at the jack place of socket, design has multiple anti-electric shock socket, as Chinese patent 98225784 disclosed technical schemes, is to adopt safety switch is set in socket, adopt multi-form safety device in addition, the prior art ubiquity, complex structure, the shortcoming of socket cost up.

Summary of the invention

In order to overcome existing electric shock-prevention safety socket complex structure, the shortcoming that manufacturing cost increases, a kind of socket of the utility model design with emergency exit, this have safety socket, not only have simple in structure, safe and reliable, and have cheap for manufacturing cost, flexible and convenient to use.

The technical scheme in the invention for solving the technical problem is: the socket that has emergency exit, comprise upper shell, lower house and jack, be provided with emergency exit between upper shell and the lower house, be provided with back-moving spring between emergency exit and the lower house, on the upper shell, be provided with the rotating shaft of emergency exit, half arc convex of emergency exit return and emergency exit spacer pin, emergency exit upper surface shape is corresponding with jack on the upper shell, and the lower surface is provided with on the emergency exit, mobile down lead, the lead cylindrical is provided with spacing preiection, the center is provided with spring eye, it is conical that lead front end cylindrical is, and also has the rotating shaft installing hole of rotating shaft on the upper shell on the emergency exit, and lower house is provided with the installing hole of lead on the emergency exit, the circumference of the bottom of installing hole is provided with the conical boss identical with the lead front end, is provided with the position-limited block of emergency exit on installing hole.

The beneficial effects of the utility model are that only when two pins of plug inserted the jack of socket simultaneously, emergency exit just can be opened automatically, when inserting the jack of socket separately, emergency exit is locked, when the pin of plug is extracted jack, the emergency exit self-return is closed jack.Advantages such as this has simple in structure, and cost is low, and is safe and reliable.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified

Fig. 1 is each part installation site schematic diagram of the utility model

Fig. 2 be Figure 1A-A to schematic diagram,

Fig. 2 be Figure 1B-B to schematic diagram,

Fig. 3 is that Fig. 1 C-C is to schematic diagram

Among the figure, 1 upper shell, 2 lower houses, 3 emergency exits, 4 rotating shafts, 5 half arc convex, 6 spacer pins, 7 jacks, 8 leads, 9 spacing preiections, 10 spring eyes, 11 rotating shaft installing holes, 12 back-moving springs, 13 installing holes, 14 conical boss, 15 position-limited blocks.

Specific embodiments

In Fig. 1, during installation, along figure axis direction, upper shell 1 and lower house 2 are buckled together, emergency exit 3 installing hole 11 interior rotating shafts 4 are around the shaft rotated, jack 7 is shut in the upper surface of emergency exit 3 (position in as figure) emergency exit 3 when off-position, when the pin of plug inserts jack, the upper surface of emergency exit 3 by pin to pressing down, because the outer figure of the front end of the lead 8 on the emergency exit 3 is conical, the conical boss 14 identical on the circumference of the bottom of Dui Ying lower house 2 installing holes 13 with it with lead 8 front ends, the front end conial vertex of lead 8 is relative with the summit of conical boss 14, two summit slide relative, cause emergency exit 3 to rotate automatically, make the summit of lead 8 advance the minimum point of conical boss 14, final emergency exit 3 is under the drive of lead 8, promptly rotate and in lower house 2, move axially again, rotation along with emergency exit 3, the upper surface of emergency exit 3 gets out of the way jack 7, at this moment lead 8 is with back-moving spring 12 compressed energy-storages in the spring eye 10, after the pin of plug is extracted, lead 8 on the emergency exit 3 is under the elastic reaction of back-moving spring 12, move up, the upper surface of emergency exit 3 is under the effect of half arc convex 5 on the upper shell 1, to opposite spin, when emergency exit 3 is moved upwards up to the home position, emergency exit 3 just in time turns to the home position, jack is closed, when firmly opening single jack 7, because emergency exit 3 is one-sided stressed, make emergency exit 3 to lopsidedness, at this moment, the spacing preiection 9 on the lead 8 enters between two position-limited blocks 15, emergency exit 3 can't be rotated and can not open emergency exit 3, spacer pin 6 on the upper shell 1 is used to limit emergency exit 3 rotational angles, guarantees that emergency exit 3 remains at the service position.
