Abstract

The utility model provides a telescopic power socket, which comprises pluralities of plug sub bodies. The plug sub bodies are combined in a lined form, each two adjacent plug sub bodies are movably connected, one plug sub body of each two adjacent plug sub bodies is provided with a first connecting port while the other plug sub body is provided with a second connecting portion, the second connecting portion and the first connecting portion are movably connected, a telescopic body is connected between each two adjacent plug sub bodies, and the ends of the telescopic bodies are fixed and arranged inside the plug sub bodies. The telescopic power socket has two using states, namely an expanding state and a shrinking state; when in the expanding state, each two adjacent plug sub bodies are not connected, the telescopic body can be stretched through external force, and then a distance between the adjacent plug sub bodies is enlarged so as to be favorable for plugs with various shapes to be plugged optionally; when in the shrinking state, the telescopic body is completely arranged into the plug sub bodies, and the longitudinal size of the telescopic power socket is reduced so as to be favorable for saving space. The telescopic power socket is simple in structure and convenient for production and assembly.

Description

Flexible insert row

[technical field]

The utility model is a kind of flexible insert row, particularly a kind of flexible insert row simple in structure.

[background technology]

The China's Mainland patent application discloses a kind of automatically flexible socket for No. 200620101924.1, mainly comprise by right shell and left shell and be fixed together the housing that forms, have entrance hole and wire hole on the housing, in housing, be provided with core, be wound with electric wire on the cannelure on the core, be provided with affixed with it scroll spring in the inner chamber of core, be and drive the wire connecting jack shaft with it, have the ratchet that matches with the self-locking ratchet on the electric wire jack shaft, be socketed with copper ring, insulator and electric wire intermediate shaft cap on the electric wire jack shaft successively and be fixedly supported on the supporting base; Electric wire pierces into from entrance hole, is connected with electric wire on the core cannelure by the through hole in insulator, copper ring, the electric wire jack shaft successively.

Although the 200620101924.1st of China's Mainland patent application takes up space few, and be easy to use, can bounce back automatically, can be fixed on neatly on wall or the ceiling, be not subjected to the restriction of working space.But the complex structure of described patent is unfavorable for producing and assembling.

[summary of the invention]

Main purpose of the present utility model is to provide a kind of flexible insert row simple in structure.

To achieve the above object, the utility model provides a kind of flexible insert row, it comprises some grafting splits, described grafting split is the strip columnwise combination, movable connection between adjacent two grafting splits, one grafting split is provided with first connecting portion, and another grafting split is provided with second connecting portion, the movable connection between second connecting portion and first connecting portion; Connect extrusome between the adjacent grafting split, and the end of described extrusome is fixed and is contained in the grafting split.

Compared with prior art, the flexible insert row of the utility model has two kinds of user modes, i.e. extended configuration and contraction state; Under extended configuration, remove annexation between two adjacent grafting splits, can make extrusome be in the state that is stretched by the external force drawing, at this moment, the distance between the adjacent grafting body increases, and the plug that helps the different shape attitude is pegged graft arbitrarily; And under contraction state, be connected and fixed between two adjacent grafting splits, and extrusome is contained in the grafting split fully, and the longitudinal size of flexible insert row dwindles, and helps saving the space.Of the present utility model simple in structure, be convenient to produce and assembling.

[embodiment]

See also Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, the flexible insert row of the utility model comprises some grafting splits 10, described grafting split 10 is the strip columnwise combination, movable connection between adjacent two grafting splits 10, one grafting split 10 is provided with first connecting portion 11, in present embodiment, first connecting portion 11 is a draw-in groove; Another grafting split 10 is provided with second connecting portion 12, and in present embodiment, second connecting portion 12 is a fixture block; The movable connection between second connecting portion 12 and first connecting portion 11, that is, fixture block sees through draw-in groove and enters in the grafting split 10, and rotation is fixing.Grafting split 10 is provided with serrated slot 13.Connect extrusome 20 between the adjacent grafting split 10, and the end of described extrusome 20 fixes and be contained in the serrated slot 13 in the grafting split 10, in present embodiment, extrusome 20 is a helical spring.Described grafting split 10 also is provided with electric wire (figure does not show), and to be connected in parallel to the split 10 of respectively pegging graft, the two ends of described electric wire are fixed to respectively in the adjacent grafting split 10, and the curling in the shape of a spiral shape in the middle part of described electric wire.

The flexible insert row of the utility model has two kinds of user modes, i.e. extended configuration and contraction state; Under extended configuration, remove annexation between two adjacent grafting splits 10, can make extrusome 20 be in the state that is stretched by the external force drawing, at this moment, the distance between the adjacent grafting body 10 increases, and the plug that helps the different shape attitude is pegged graft arbitrarily; And under contraction state, be connected and fixed between two adjacent grafting splits 10, and extrusome 20 is contained in the grafting split 10 fully, and the longitudinal size of flexible insert row dwindles, and helps saving the space.
