Description

Plug with draw ring

Technical field

The utility model is relevant with plug, particularly relevant for a kind of plug with draw ring.

Background technology

Ginseng Fig. 4 and Fig. 5 are existing a kind of flat plug 70, and it includes: a housing 71 and two ends are hubbed at the U type draw ring 72 on this housing 70.Because the flat thin work force that is difficult for setting up of these housing 71 body portions, so, by the mode that pulls this draw ring 72, will make this plug 70 be easier on socket, pull away.

The draw ring 72 of above-mentioned old plug 70 is its two end to be made as collude shape, embed in this housing 71 to collude the mode of establishing again, when the pulling force of bestowing as the user is bigger than the adhesion of 71 of this draw ring 72 and this housings, this draw ring 72 will produce distortion and separate with this housing 71, if the user does not examine, will have and fall or the possibility that palm throws away and hard thing collides.

Novel content

Main purpose of the present utility model is to provide a kind of plug with draw ring, its draw ring and housing combine that more shape is tight, do not have the situation that draw ring comes off from housing and take place in the middle of using, with the safety of guaranteeing that the user uses.

A kind of plug with draw ring that the utility model provides is characterized in that it includes:

One hollow housing, it has two and connects and establish portion;

At least two electric-conductors are arranged in this housing;

One electric wire, it is arranged in this housing and is connected these electric-conductors;

One draw ring, it generally is the U type, two ends have a pivot hole respectively, this draw ring is cross-placed on this housing, make this two pivots hole to should housing two meet the portion of establishing; And

Two pivot spares pass two pivot holes of this draw ring movably, and respectively with an end and this housing one this meet the portion of establishing and combine, respectively this pivot spare other end has a stopper, this stopper diameter is bigger than the pivot bore dia of this draw ring.

Wherein the portion of establishing that connects of this housing is for being embedded at an embedding seat of its body portion respectively, respectively this embedding seat and have a screw; These pivot spares one end tool respectively is located in order to spiral shell in the screw of each embedding seat of this housing with a screwing section, and its other end forms this stopper.

Wherein this housing has a groove, and this draw ring has a lug and must be against on the groove of this housing.

Thus, this housing rotation relatively of this draw ring, and influenced down by the barrier effect that stopper produced of this two pivot spare, can guarantee the marriage relation of this draw ring and this housing.

Description of drawings

For illustrating in greater detail structure of the present utility model, following conjunction with figs. and embodiment explanation as after, wherein:

Fig. 1 is the three-dimensional exploded view of the utility model one preferred embodiment.

Fig. 2 is the three-dimensional combination figure of the utility model one preferred embodiment.

Fig. 3 is the action schematic diagram of the utility model one preferred embodiment, shows that the lug of draw ring embeds in the groove of shell.

Fig. 4 is existing a kind of plug three-dimensional exploded view.

Fig. 5 is existing a kind of plug three-dimensional combination figure.

Embodiment

At first consult Fig. 1, be the plug 10 of the utility model one preferred embodiment, it includes: a housing 20, three electric-conductors 30, an electric wire 40, a draw ring 50 and two pivot spares 60.

Cooperate Fig. 2 and Fig. 3, the hollow housing that this housing 20 mainly is made up of a top shell 21, a drain pan 22 and two embedding seats 23,24, and after these top drain pan 21,22 combinations, in have a room 25, have two at its side face relative position and hold hole 211,212, at its end face 221 lateral margins and have a groove 222, its 223 precalculated positions, bottom surface then are provided with plurality of through holes 224.In addition, this two embeddings seat the 23, the 24th embeds this and two holds in hole 211,212, and then forms one respectively in these housing 20 2 sides and meet the portion of establishing, moreover, respectively this embedding seat 23,24 have a screw 231,241 reveal existing in outside.

These electric-conductors 30 are to make with conducting metal, and the mode that its grade is established with ring is penetrated in the room 25 of this drain pan 22 by the perforation 224 of this drain pan 22.

40 in this electric wire is to be penetrated in this room 25 by these housing 20 1 side edge, and itself and be connected with these electric-conductors 30.

This draw ring 50 is essentially a U type metal wire body or an Elastic plastic-rubber bar, be provided with two pivot holes 51 at its two ends, and 51 in this two pivots hole is on same axial line, in addition, these draw ring 50 body portion stage casings have a taper lug 52, and these lug 52 tips and its body portion two ends are in the same way; Be with, this draw ring 50 can be striden and will be located on this housing 20, make its two pivots hole 51 relative with two screws 231,241 of this housing 20, this lug 52 then is right against the groove 222 of this housing 20.

These pivot spares 60 are respectively a bolt, its body portion one end has a thread segment 61, must be locked in the screw 231,241 of this embedding seat 23,24, its other end then is provided with the block stopper 62 of a ring, these stopper 62 diameters are bigger than pivot hole 51 diameters of this draw ring 50, pivotally the thread segment 61 of this two pivot spare 60 is worn the two pivot holes 51 that pivot is crossed this draw ring 30, locked again in two screws 231,241 of this housing 20.

Be with, the stopper 62 of this two pivot spare 60 can prevent that these draw ring 50 2 ends break away from its body portion.In other words, promptly be not have the wheel user how to exert all one's strength and pull this draw ring 50, these draw ring 50 two ends positively are hubbed at this housing 20 2 sides at last, and thus, the draw ring that can improve old plug is easy to generate the problem that comes off when excessive pullling strength.In addition, when this draw ring 50 does not use, can be placed on the groove 222 of this housing 20 by its lug 52 pivots, make that these draw ring 50 unlikely rotations are excessive, and interfere with the position of these electric-conductors 30 of grafting usefulness.
