The stopping device of the turning shaft structure that the utility model provides, this pivot at least one torsion spring of socket between movable part and fixed block wherein, its two ends prop up movable part and fixed block respectively.Moreover this torsion spring set is connected to a sleeve pipe, is passed through by this pivot again.

For further disclosing concrete technology contents of the present utility model, at first see also accompanying drawing.

As shown in Figure 1, basically, turning shaft structure of the present utility model is by a fixed block 1, one movable part 2, one pivots 3, and a clip assembly 4 combines.

Wherein, this fixed block 1 and movable part 2 are known assembly, behind its both joints, connect with pivot 3, this movable part 2 are rotated, to adjust folding angle between the two with respect to fixed block 1.

This fixed block 1 is vertical extent one fin 12 separately in a base plate 11 both sides, and it is provided with one relatively and connects hole 13, for after chat pivot 3 and pass through.Wherein, a plurality of open-works 14 are offered on these base plate 11 surfaces, utilizing known coupling unit, and after for example screw passes through, and the locking pedestal.

Movable part 2 is to hang down separately at a horizontal frame plate 21 two ends to establishing a lug 22, and each lug 22 is in abutting connection with a fin 12, and correspondence connects 13 positions, hole and be oppositely arranged axis hole 23, passes through connection for this pivot 3.A plurality of plate holes 24 are offered on these frame plate 21 surfaces, and it can utilize known coupling unit, after for example screw passes through, and is locked in a supporting component, for example connects the lower end of plate, and its upper end then connects a liquid crystal display.

In fact, this fixed block 1 and movable part 2 also can be by the variations of appearance, and directly become a pedestal and a supporting component, and only this all is the migrating or extend of known technology, and does not intend giving unnecessary details at this.

Pivot 3 is a body of rod, and the axis hole 23 that connects hole 13 and movable part 2 that it passes through this fixed block 1 makes this movable part 2 be rotated with respect to fixed block 1, and has the function of rotating shaft.As shown in the figure, the body of rod of this pivot 3 is provided with a pair of flat bevel 31 relatively, the appearance that respectively connects hole 13 then is consistent with these pivot 3 sections, and the formed adapter section 32 of its free end, for example thread section in the fin 12 of fixed block 1 connect 13 outsides, hole and an end sealing 33, for example the anticreep nut in conjunction with and form fixing.

Clip assembly 4 is a lug 22 outsides that are fixedly arranged on movable part 2 by a rotary seat 41, its hollow seat chamber 411 inner side edge central authorities open a through hole 412, pass through for pivot 3, the a plurality of chuck teeth 413 that have the annular of being arranged in addition in its outer side surface periphery, and prominent at least two trips 414 of establishing of inner side surface periphery, so that be intercalated in this lug 22 corresponding tongue-and-grooves 25 that are provided with, make this rotary seat 41 be fixedly arranged on a lug 22 outsides, and interlock with it.Hollow seat chamber 421 outer side central authorities with a sliding seat 42 open a perforation 422 in addition, pass through for pivot 3, the corresponding chuck tooth of its inner side surface periphery 413 positions are oppositely arranged a plurality of snapping dish teeth 423, and two chambers 411, insert an elastic component 43 that supplies pivot 3 to pass through for 412, spring for example, when making these sliding seat 42 outer side be subjected to the side direction external force of an applicator member 44, promptly move towards rotary seat 41, and compress this elastic component 43, the snapping dish tooth 423 of its inboard periphery and the chuck tooth 413 of rotary seat 41 are meshed each other, and form the locking state of stop according to this.

As shown in Figure 1, the formation of this side direction external force, be by an applicator member 44, the outboard end of this pivot 3 of race 442 sockets of 441 on handle top two cams for example, and in radially articulating this pivot 3 with a pivot pin 443, its both sides make this handle 44 and pivot 3 unlikely radial separation again with cramp 444 snappings.By pull these handle 44 bottoms sheet 445, make this cam 441 be converted to long limit by minor face, can make this sliding seat 42 move towards rotary seat 41, and in conjunction with after stereogram, as shown in Figure 2.Wherein, the formation of this applicator member 44, the cam structure with Figure 1 and Figure 2 does not exceed, during its practice, also be able to rotary member, for example a spiral cover, perhaps be the two-part buckle pieces, for example push type is jumped bond structure for it, also can reach the effect of identical formation side direction external force.

For making this movable part 2 be supported supported object, the weight of supporting component and liquid crystal display for example, this pivot 3 gets at least one torsion spring 5 of socket between movable part 2 and fixed block 1, its two ends prop up movable part 2 and fixed block 1 respectively, and interfere for avoiding those torsion springs 5 to form with pivot 3, so those torsion springs 5 are socketed on a sleeve pipe 51, are passed through by this pivot 3 again.

As shown in Figure 3, it is the sectional drawing that is intercepted along Fig. 2 center line A-A, the cam 441 long limits of this handle 44 produce a lateral pressure to sliding seat 42, make it when rotary seat 41 moves, compression elastic component 43 between the two, and its snapping dish tooth 423 and chuck tooth 413 meshed each other, because this pivot 3 is to be the state of maintaining static in fixed block 1, this movable part 2 meshes with sliding seat 42 each other because of the rotary seat 41 that side direction connected, and present the locking state of clip, this movable part 2 can't be rotated on pivot 3.

See also Fig. 4 and Fig. 5, as desire to carry out release, and only must pull this handle 44, make its cam 441 be converted to minor face by long limit, and make this slip base 42 because of losing pushing of external force, and by the stretching, extension of this elastic component 43, and slide laterally, thereby make this snapping dish tooth 423 and chuck tooth 413 break away from, thereby lose engagement, at this moment, this movable part 2 can rotate on pivot 3 together with rotary seat 41, and removes the arrested state of clip.

That the utility model disclosed is a kind of of preferred embodiment, and claim category of the present utility model is not all taken off in Ju Bu change or modification and come from technological thought of the present utility model and be what those skilled in the art were easy to know by inference such as.
