Description

Safety socket

The utility model relates to a kind of supply socket, especially a kind of improvement structure of socket.

The supply socket of selling on the market now, no matter be two or three, and two and three multipurpose sockets that combine, its power supply reed all is Ming Lushi with the insert eye that covers on the socket, and is very dangerous.In order to improve the fail safe of socket, a large amount of technical staff have designed the safety socket of numerous types.The Patent Gazette for Utility Models that Patent Office of the People's Republic of China (PRC) publishes has been announced the patent application case (notification number: CN2059024U) that name is called " rotation pessimistic securit socket " July 4 nineteen ninety, its technical solution mainly is that rotation cover seals the power supply reed under the effect of extension spring, during use rotation cover is rotated to an angle, the power supply reed is revealed, and plug just can insert wherein; When dialling plug, rotation cover resets, and the power supply reed is covered firmly, so reaches purpose safe in utilization.Resetting of this technical solution cover plate realizes by extension spring, the potential difference that misplaces simultaneously is bigger, promptly differ an angle of 90 degrees, extension spring its deformation at work is bigger, extension spring itself exceeds its elastic limit most probably, spring body after it elongates will bear against inevitably on submerged plate, will cause the extension spring cisco unity malfunction when serious, so that influences normally resetting of cover plate; Because cover plate is rotating part, so this kind socket is not suitable for using having on the combined multipurpose socket of independent cap, even be used for two sockets, as when being fixed on the wall, its cover plate also will protrude wall plane, and is promptly not attractive in appearance, also is in the way.

The purpose of this utility model provides a kind of upper cover body and fixes, and is suitable for making two or three s' safety socket, also is suitable for making having the multipurpose socket that single upper cover body is used simultaneously for a plurality of plugs.

Technical solution of the present utility model is achieved in that a kind of safety socket, it comprises the Socket casing of being made up of loam cake (1) and pedestal (2), enclosure interior pedestal (2) is provided with brace (3) and the reed (4) that joins with power line, jack on the fixed head (5) is positioned at reed (4) top and consistency from top to bottom with it, portable plate (6) can rotate around the mandrel screw (7) that is connected on the pedestal (2), when portable plate (6) rotates its go up that set jack can be in respectively that jack on the same fixed head (5) misplaces or positions aligning on, its special feature is that portable plate (6) is located between loam cake (1) and the fixed head (5), the end face of loam cake (1) is provided with window, the track when window can be bright expose jack on the portable plate (6) and jack and rotates; Mandrel screw (7) middle part that head links to each other with pedestal is with torsion spring (8), and an end of torsion spring (8) is fixing with respect to pedestal (2), and the other end is connected on the portable plate (6); Fixed head (5) is positioned on the bearing (10) that links to each other with pedestal (2).

In the utility model technical solution, described torsion spring (8) outside is provided with an insulating case (9) that is fixed on the pedestal (2), torsion spring (8) and reed (4) are kept apart, this insulating case (9) upper end extends also coupled in the set hole, fixed head (5) center in, and this can be avoided reed (4) to contact with torsion spring (8) causing the charged danger of mandrel screw (7).

In the utility model technical solution, an end of above-mentioned torsion spring (8) inserts in the notch set on the sidewall of insulating case (9), and the other end is fixed in the groove set on the face of being close to fixed head (5) on the portable plate (6).

In the utility model technical solution, described bearing (10), its center has through hole, and top end face is provided with the concave station face, and the bottom surface is provided with the support leg (11) that several same pedestals (2) link to each other.

In the utility model technical solution, portable plate (6) is that the dependence torsion spring realizes automatically reset, makes two or three safety sockets, and its compact conformation is reliable; In addition, loam cake is connected as a single entity with pedestal, and portable plate places in the loam cake, and this textural association is convenient, provides possibility for making Safety multipurpose socket.

Below in conjunction with drawings and Examples the utility model is done further to describe in detail.

Embodiment

Pedestal (2) is pressed the known method injection mo(u)lding, and pedestal (2) is provided with brace (3) and the reed (4) that links to each other with power line.Establish a garden shape window on the top end face of loam cake (1), its window slightly larger in diameter is in the spacing of reed (4), to guarantee that plug can normally insert.In the Socket casing by loam cake (1) and pedestal (2) formation, pedestal (2) is gone up and is connected a bearing (10), referring to accompanying drawing 1.Referring to accompanying drawing 4 and accompanying drawing 5, bearing (10) is a book Cylinder, and its center is provided with through hole, and top end face is provided with the concave station face, is provided with the same pedestals of two support legs (11) (2) below the bearing (10) and links to each other.Referring to accompanying drawing 1, the inner top surface of the top end face snap loam cake (1) of bearing (10), the similar portable plate (6) of size are superimposed upon in the cavity that places loam cake (1) and bearing (10) formation on the fixed head (5).Fixed head (5) is gone up and to be had two jacks corresponding to reed (4), and fixed head (5) center is provided with a square hole, and this square hole is set on the head that is positioned at the four prismatic insulating cases (9) that pedestal (2) central vertical sets up in basal plane just.Fixed head (5) is exactly to match with the square shaft of insulating case (9) by self square hole to realize fixing with respect to pedestal (2).

Mandrel screw (7) pass from top to bottom portable plate (6), fixed head (5), and the same pedestal of insulating case (9) (2) link to each other.Go up a sheathed torsion spring (8) at insulating case (9) inner spindle screw (7), insulating case (9) plays a part torsion spring (8) and reed (4) are isolated, in order to avoid the charged danger of mandrel screw (7).Be close in the set notch of pedestal (2) on the sidewall of the one end insertion insulating case (9) of torsion spring (8), the other end inserts on the portable plate (6) to be close in the groove set on the end face of fixed head (5).Portable plate (6) can rotate around mandrel screw (7), and can be returned on it bit position that interlaces of jack eye on jack eye and fixed head (5) under the effect of torsion spring (8).

The technical scheme of three sockets of safety does not have big difference with above-mentioned scheme.

For Safety multipurpose socket, its loam cake and pedestal are still common, only need two every pair or three reeds, and relative set one cover fixed head and portable plate, technical scheme does not also have difficulty.

In the utility model technical solution, except that relevant trip bolt, reed, spring, other member is made by insulating material.
