Abstract
The utility model discloses a locking pull -off plug belongs to electric wire plug technical field, and this locking plug that takes off comprises insulating housing, metal male tab, driving lever, rubber bullet strip, fixed block etc.. Two parts about insulating housing divide into, be provided with four little stands of notch cuttype down on the insulating housing, two that are close to the front end are used for two fixed driving levers of being made by insulating material, two of the rear end are used for two fixed metal male tab, two driving levers and two metal male tab homoenergetics rotate certain angle round the little stand of respective notch cuttype, its pivoted angle is by descending the groove restriction of opening on the insulating housing, before locking plug that takes off insert the plug, the state of leanin is stirred two metal male tab to the accessible driving lever, the metal male tab of plug and the friction between the socket sheetmetal have been avoided in inserting processes, thereby metal male tab's wearing and tearing have been reduced, its life has been prolonged to a certain extent, two about intermediate positions of metal male tab respectively are fixed with the fixed block that an insulating material made, it has a screw hole to open on every fixed block, available screw is fixed the both ends of rubber bullet strip on two fixed blocks, the elasticity of rubber bullet strip makes metal shrapnel lean out through the fixed block. In addition, the tip of two metal male tab side respectively is provided with an arch, forms hook -likely with metal male tab, and under operating condition, the hook that metal male tab can be has firmly prevented effectively that the pine of plug from taking off on the socket sheetmetal.
Description
Technical field
The utility model relates to wire and plug technical field, specifically a kind of Plug preventing looseness.
Background technology
In daily life, plug is seen everywhere, most of electrical appliances that we use, and the large little mobile phone, walkman etc. often used to us of some process equipments that arrive all be unable to do without plug.Common plug is made up of the insulation shell of two metal inserts and outside thereof, this plug construction is simple, but, after long-time use, because wearing and tearing can cause plug to be easy to loosen or come off, this will the unexpected power-off when we use electrical appliance, thus affect our normal work, even there are some electric equipments in the course of the work, if power-off suddenly can lose some important informations, be with to us and serve irreparable damage, even if just loosen and there is no power-off, make the part metals inserted sheet of plug outside exposed, also be a kind of potential danger.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide the simple Plug preventing looseness of a kind of structure, thus makes us more relieved when using various power consumption equipment.
The technical scheme that the utility model adopts is: a kind of Plug preventing looseness, and it is made up of insulation shell, metal insert, driving lever, rubber spring, fixed block etc.Insulation shell is divided into upper and lower two parts, lower insulation shell (2) is provided with four notch cuttype posts, two of close front end for fixing two driving levers be made up of insulating material (5), two of rear end for fixing two metal inserts (1), two driving levers (5) and two metal inserts (1) all can rotate certain angle around respective notch cuttype post, its angle of rotating is limited by the groove that lower insulation shell (2) is opened, the fixed block (6) that an insulating material is made respectively is fixed with in the about centre position of two metal inserts (1), each fixed block (6) has a screwed hole, the two ends of rubber spring (7) are fixed on two fixed blocks (6) by available screw (3), the elastic force of rubber spring (7) makes metal insert (1) outward-dipping by fixed block (6).
Described Plug preventing looseness, two metal inserts (1) can be rotated around respective notch cuttype post under the effect of two driving levers (5), before plug insertion socket, by driving lever (5), two metal inserts (1) are toggled it to intilted state, avoid the friction between the metal insert (1) of plug and socket sheet metal (8) during insertion, thus decrease the wearing and tearing of metal insert (1), extend its useful life.
Described Plug preventing looseness, the end of two metal insert (1) sides is respectively provided with a projection, is formed hook-shaped, in working order with metal insert (1), metal insert (1) can be hooked on socket sheet metal (8) firmly, effectively prevent getting loose of plug.
Compared with prior art, the beneficial effects of the utility model are: effectively prevent getting loose of plug in use procedure, eliminate potential safety hazard, more relieved when let us uses.Reasonable in design, be skillfully constructed novelty, is easy to apply.
Accompanying drawing explanation
Fig. 1 be the present invention when not working upper insulation shell (4) open after structural representation.
Fig. 2 is the schematic diagram after the present invention removes upper insulation shell (4) when working.
Fig. 3 is lower insulation shell (2) structural representation.
In figure: 1 is metal insert, 2 is lower insulation shell, and 3 is screw, and 4 is upper insulation shell, and 5 is driving lever, and 6 is fixed block, and 7 is rubber spring, and 8 is socket sheet metal.
Embodiment
Below in conjunction with accompanying drawing, this programme embodiment is described in detail.
As shown in Figures 1 and 2, Plug preventing looseness of the present invention is made up of insulation shell, metal insert, driving lever, rubber spring, fixed block etc.Insulation shell is divided into upper and lower two parts, lower insulation shell (2) is provided with four notch cuttype posts, two of close front end for fixing two driving levers be made up of insulating material (5), two of rear end for fixing two metal inserts (1), two driving levers (5) and two metal inserts (1) all can rotate certain angle around respective notch cuttype post, its angle of rotating is limited by the groove that lower insulation shell (2) is opened, before plug insertion socket, by driving lever (5), two metal inserts (1) are toggled it to intilted state, avoid the friction between the metal insert (1) of plug and socket sheet metal (8) during insertion, thus decrease the wearing and tearing of metal insert (1), the fixed block (6) that an insulating material is made respectively is fixed with in the about centre position of two metal inserts (1), each fixed block (6) has a screwed hole, the two ends of rubber spring (7) are fixed on two fixed blocks (6) by available screw (3), the elastic force of rubber spring (7) makes metal insert (1) outward-dipping by fixed block (6).
The end of two metal insert (1) sides is respectively provided with a projection as shown in Figure 3, is formed hook-shaped with metal insert (1), and in working order, metal insert (1) can be hooked on socket sheet metal (8) firmly, effectively prevent getting loose of plug.
