Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of notebook adapter is provided, by set up four grooves in the bottom surface of housing, in each groove, pass through fixed bar fixed block, make by four pulleys, the bottom surface of housing to be erected not and the plane contact of placing the pulley rolling while dragging electric wire on housing, the wearing and tearing that can effectively avoid the direct kiss the earth of adapter face to form, and make adapter be not easy to make dirty, increase serviceable life.
The utility model specifically solves the problems of the technologies described above by the following technical solutions:
A kind of notebook adapter, comprise housing and the circuit board that is positioned at housing, described circuit board connects the input-output line of housing both sides, on described housing bottom surface, be provided with four grooves, in each groove, be provided with pulley and fixed bar, described fixed bar is fixed on groove through behind the axle center of pulley; The distance of shaft centers of described pulley distance is overhead greater than the distance of housing bottom surface apart from ground.
As a kind of optimal technical scheme of the present utility model: also comprise the mudflap for barrier, described mudflap is fixed on each fixed bar.
As a kind of optimal technical scheme of the present utility model: be fixed with the clamp for tying up input-output line on the surface of described housing.
As a kind of optimal technical scheme of the present utility model: be provided with Saw blade on the inwall of described clamp.
As a kind of optimal technical scheme of the present utility model: described fixed bar is U-shaped bar; Described fixed bar is welded on groove.
The utility model adopts technique scheme, can produce following technique effect:
The utility model provides a kind of notebook adapter, by set up four grooves on the surface of housing, in each groove, by fixed bar, fix pulley, by four pulleys, the bottom surface of housing is erected not and the plane contact of placing, pulley rolling while dragging electric wire on housing, the wearing and tearing that can effectively avoid the direct kiss the earth of adapter face to form, and make adapter be not easy to make dirty.Fixed bar is U-shaped bar, and fixed bar is welded on groove, adopts this structure, utilizes the stability of U-shaped bar, make the axle center of pulley be not easy to depart from, and welding manner is more stable and firm.In addition, be fixed for the mudflap of barrier in fixed bar inner side, what make that each pulley produces in rolling is dirty by mudflap barrier, prevents that the dirt in groove from piling up the rolling that hinders pulley.When packing up adapter, can tie up input-output line by clamp, make the smaller volume of depositing of adapter, facilitate the placement of whole adapter.The inwall of clamp is provided with Saw blade, can further improve the fixation to input-output line, by Saw blade, increases holding force, and the friction force of input-output line and clamp inwall is increased, and is more conducive to clamping.Therefore, the utility model makes improvements adapter structure, makes it in use avoid wearing and tearing, conveniently pulls, and is conducive to containment vessel surface, thereby increases serviceable life, makes it can better offer people and uses.
Accompanying drawing explanation
Fig. 1 is the structural representation of notebook adapter of the present utility model.
Wherein label is explained: 1-housing, 2-input-output line, 3-fixed bar, 4-pulley, 5-mudflap, 6-clamp, 7-Saw blade.
Embodiment
Below in conjunction with Figure of description, embodiment of the present utility model is described.
As shown in Figure 1, the utility model has designed a kind of notebook adapter, comprise housing 1 and the circuit board that is positioned at housing 1, described circuit board connects the input-output line 2 of housing 1 both sides, on described housing 1 bottom surface, be provided with four grooves, in each groove, be provided with pulley 4 and fixed bar 3, described fixed bar 3 is fixed on groove through behind the axle center of pulley 4; The distance of shaft centers of described pulley 4 distance is overhead greater than the distance of housing 1 bottom surface apart from ground.By four pulleys 4, the bottom surface of housing 1 is erected,, with the plane contact of placing, the pulley 4 while dragging electric wire on housing 1 does not roll, the wearing and tearing that can effectively avoid the direct kiss the earth of adapter face to form, and make adapter be not easy to make dirty.
For fixed bar 3, it can be the known configurations for fixed block 4 in prior art, if fixed bar 3 can be U-shaped bar, each fixed bar 3 is welded on each groove, adopt this structure, utilize the stability of U-shaped bar, make the axle center of pulley be not easy to depart from, and welding manner is more stable and firm.
In addition, when the pulley 4 in 4 grooves rolls, easily the dust earth on ground is brought in groove, in order to prevent the dirt in groove, bring into and pile up, in each fixed bar 3 inner sides, be fixed for the mudflap 5 of barrier, what make that each pulley 4 produces in rolling is dirty by mudflap barrier, effectively avoids earth in groove to hinder the rolling of pulley 4.
When packing up adapter, can be undertaken by being fixed on the lip-deep clamp 6 of housing 1, the width of clamp 6 can be definite with actual needs, and clamp 6 is tied up input-output line 2, makes the smaller volume of depositing of adapter, facilitates the placement of whole adapter.
In order further to improve the fixation to input-output line 2, by being provided with Saw blade 7 on the inwall at clamp 6, Saw blade 7 increases the holding force of clamp 6, and input-output line 2 and the friction force of clamp 6 inwalls are increased, and is more conducive to clamping.
An embodiment of the present utility model as shown in Figure 1, press foregoing description and form adapter, 4 grooves are set on the bottom surface of housing 1, fixing fixed bar 3 and pulley 4 in each groove, on fixed bar 3, be fixed with mudflap 5, on the upper surface of housing 1, be provided with a clamp 6, the width of clamp 6 is less than the width of housing 1, on clamp 6 inwalls, is furnished with Saw blade 7.While dragging input-output line 2 when using adapter, because the distance of shaft centers of pulley 4 distance is overhead greater than the distance of housing 1 bottom surface apart from ground, by 4 pulleys 4, the bottom surface of housing 1 is propped up, housing 1 bottom surface can not contacted with ground, thereby effectively prevent the wearing and tearing on housing 1 surface, and mudflap 5 plays the effect of anti-gray barrier.When packing up, input-output line 2 to be rolled and is clipped in clamp 6, input-output line 2 contacts with Saw blade 7, increases friction force, makes to clamp better effects if.
Therefore, the utility model makes improvements adapter structure, makes it in use avoid wearing and tearing, conveniently pulls, and is conducive to containment vessel surface, thereby increases serviceable life, makes it can better offer people and uses.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from the utility model aim, make a variety of changes.
