See also Fig. 1 and Fig. 2, the utility model better embodiment computer chassis header board locked instrument is used for a header board 20 is locked at a pedestal 10, and this computer chassis header board locked instrument comprises a pedestal 10, a pair of torsion spring 30, a pair of pulling piece 40 and a pair of locking part 50.

This pedestal 10 comprises that two

side

11,12 and connects the diapire 14 of this two

side

11,12, what the front end of this sidewall 11 offered a strip wears groove 112, this wear near this sidewall 11 rear end of groove 112 on the ora terminalis flanging 114 that bent inwards, on this flanging 114, offer a screw 116 and a perforation 118 corresponding with torsion spring 30 1 ends.The front end of this sidewall 12 also offer one with wear the groove 112 corresponding grooves 122 of wearing, this wear near this sidewall 12 rear end of groove 122 on the ora terminalis flanging 124 that also bent inwards, on this flanging 124, also offer a screw 126 and a perforation 128 corresponding with another torsion spring 30 1 ends.Be provided with a fixing mouth 141 that is bridge shape in the front end of this diapire 14.

This header board 20 is installed on panel 22, on this header board body 21 by a header board body 21, and is riveted on the sliding panel 25 that carrier 23 and on this header board body 21 is riveted on these header board body 21 1 ends and is combined to form.The following ora terminalis of this header board body 21 also level inwardly convex with one with this pedestal 10 on fixing mouth 141 corresponding inserted sheets (figure show).This carrier 23 is in order to carry a data-carrier store, it comprises a sidewall 231 and a diapire 237, this sidewall 231 can be used for serving as a sidewall of this header board 20, it outwards convexes with the projection 232 that two correspondences are worn groove 112, these sidewall 231 apical margins bend inwards and form a flanging 233 that is parallel to this diapire 237, and these flanging 233 upper punches are provided with a rectangular leg-of-mutton catch 234.This sliding panel 25 also can serve as another sidewall of this header board 20, its middle part also outwards convexes with the projection 252 (referring to Fig. 6) that two correspondences are worn groove 122, the last ora terminalis of this sliding panel 25 also inwardly vertically has been bent to form a flanging 254, and these flanging 254 rear ends also vertically are bent to form straight up a lug 256.

These pulling piece 40 front ends are provided with a pulling part 42, be formed with one on this pulling part 42 in the inner part and have the introduction part 422 on inclined-plane, these pulling part 42 lower ends also are provided with a resettlement section 424, the rear end of this pulling piece 40 also convexes with two

relative projectioies

43,44 downwards, this two

projection

43,44 is equipped with a wedge shaped projection 432,442, the rear end of this two

projection

43,44 also convexes with a cylinder 46 that offers through hole 461, this shifting part 40 of a side at this cylinder 46 also inwardly convexes with a pressure section 47, and this shifting part 40 also convexes with a projection 48 downwards in the back of this cylinder 46; This torsion spring 30 is set on this cylinder 46, and the one end is sandwiched between this two

projection

43,44 and is kept out by the wedge shaped projection 432,442 of this two

projection

43,44 and be unlikely to make this torsion spring 30 to come off.

Please continue to consult Fig. 3 and Fig. 4, when pulling piece 40 is installed, at first torsion spring 30 is set on the cylinder 46 of pulling piece 40, an end that firmly presses down torsion spring 30 makes it inwardly slide and kept out by the wedge shaped projection 432,442 of two

projectioies

43,44 and be unlikely to make torsion spring 30 to come off along wedge shaped projection 432,442, the other end inserts in the perforation 118, then, locking part 50 is passed that through hole 461 on the pulling piece 40 cooperates with screw 116 can be with pulling piece 40 lockings on the sidewall 11 of this pedestal 10, pulling piece 40 under the effect of torsion spring 30 near the sidewall 11 of this pedestal 10.Using the same method can be with 40 lockings of another pulling piece on another sidewall 12 of this pedestal 10, pulling piece 40 under the effect of torsion spring 30 also near the sidewall 12 of this pedestal 10.Like this, this two pulling piece 40 just is fixed on this pedestal 10.

Please continue to consult Fig. 5 and Fig. 6, when this header board 20 is installed, the projection 232 of the carrier 23 on this header board 20 is aimed at the projection 252 on the sliding panel 25 wear groove 112,122 on these pedestal 10 sidewalls 11,12.Then, promote this header board 20 backward, the projection 252 on the projection of this carrier 23 232 and this sliding panel 25 is worn groove 112 and this wears slip groove 122 at this respectively, and simultaneously, the inserted sheet on this header board body 21 is aimed at the fixing mouth 141 of these pedestal 10 diapires 14 front ends.When further promoting this header board 20 backward, the projection 232 of this carrier 23 and the outside respectively introduction part 422 that promotes corresponding pulling piece 40 of the projection 252 on this sliding panel 25, and finally slide into 424 inboards, resettlement section of pulling piece 40, simultaneously, inserted sheet on this header board body 21 also inserts in the fixing mouth 141 of these pedestal 10 diapires 14 front ends, at this moment, pulling piece 40 returns to original position again under the effect of torsion spring 30, at this moment, the resettlement section 424 of this two pulling piece 40 has been kept out the projection 232 of this carrier 23 respectively and the projection 252 on this sliding panel 25 moves forward, and, the fixing mouth 141 of these pedestal 10 diapires 14 front ends is kept out the further motion backward of inserted sheet of 21 times ora terminalis of this header board body, like this, this header board 20 just is fixed on this pedestal 10.

When dismantling this header board 10, both hands are simultaneously firmly to these pedestal 10 sidewalls 11, the pulling part 42 that 12 outsides promote pulling piece 40 makes pulling piece 40 outwards rotate around locking part 50, at this moment, the resettlement section 424 of this two pulling piece 40 also laterally the rotation respectively with this two projection 232,252 mutually break away from and can make way for this two projection 232,252, simultaneously, the catch 234 that the pressure section 47 of this two pulling piece 40 compresses respectively on this carrier 23 moves forward this header board 20 with lug 256 on this sliding panel 25, in the resettlement section 424 of this two pulling piece 40 respectively with this two projection 232,252 break away from fully after, discharge the pulling part 42 of this two pulling piece 40, then, spur forward this header board 10 on this header board body 21 inserted sheet and the fixing mouth 141 of this pedestal 10 break away from fully, at this moment, this two pulling piece 40 sets back under the effect of torsion spring 30 separately.Like this, this header board 20 can take off from this pedestal 90.

Certainly, torsion spring 30 in the utility model better embodiment is also replaceable to be other flexible member, as long as can realize effect that this pulling piece 40 is resetted, in addition, also can only on a sidewall 11 of pedestal 10, be provided with stationary installation in the utility model better embodiment, but and on another sidewall 12 of pedestal 10, make also fixed front plate 10 of corresponding design alteration.
