Embodiment

For the ease of those skilled in the art's understanding, the present invention is done further description below in conjunction with accompanying drawing.

Like accompanying drawing 1, shown in 2, a kind of deck drawer structure of digital product comprises housing 1 and is loaded on the deck 2 on this housing 1; Be equiped with drawer 3 on the housing 1, have the through hole that supplies drawer to inject on the housing 1, installing stopping means 4 on the said housing 1; This stopping means 4 comprises location compressing tablet 41, position limiting slide block 42 and limit spring 43; Position limiting slide block 42 and location compressing tablet 41 activity attachings, limit spring 43 is sleeved on the position limiting slide block 42, offers the hole that supplies the drawer turnover on the position limiting slide block 42.Location compressing tablet 41 fixedly is loaded on the housing 1, will locate compressing tablet 41 through screw or screw etc. and be installed on the housing 1, and there are the gap in

location compressing tablet

41 and 2 of decks; Position limiting slide block 42 is a Jiong shape; Limit spring 43 is sleeved on the two side arms of position limiting slide block 42, and the side arm activity of position limiting slide block 42 interted location compressing tablet 41, and limit spring 43 is pressed position limiting slide block 42; Position limiting slide block 42 is played the effect of precompressed, the transverse arm of position limiting slide block 42 is closely contacted with the inwall of housing 1.Offer the through hole that supplies drawer to go out on the housing 1, make the slit between through hole and drawer as far as possible little when specifically making, guarantee the overall appearance of product, simultaneously drawer is played certain position-limiting action.The location compressing tablet can be made carnival hat shape and install across crossing deck, or the two-section of just making disconnection is installed on the housing respectively.

In addition; The deck that the utility model is chosen is on the market-deck of push form, promptly possess pin drawer, push ejects the version of drawer again, but it has been done improvement to a certain degree; Promptly on deck, be symmetrically arranged with positive stop spring plate in the left and right sides of the port of confession drawer turnover; It is spacing that drawer is received when bullet advances to eject deck, guarantees that bullet advances to eject effect, and it is relatively large that volume is done.

Like accompanying drawing 3, shown in 4; Cross-sectional view for deck; Comprise loam cake 21, spring 22, slide block 23, tuck 24, main body 25 and shell fragment 5, on the main body 25 that spring 22 1 ends are sleeved on the slide block 23, the other end is sleeved on deck 2, slide block 23 activities are loaded in the corresponding recesses of offering on the main body 25; Offer gathering sill on the slide block 23; Tuck 24 tail activities are loaded in the blind hole offered on the main body 25, front end is movably placed in the gathering sill on the slide block 23, because the gathering sill bottom is that tandem array and ladder are uneven, promptly climbs one section slope and fall into next step then, climb one section slope and then fall into next step again; Therefore, tuck 24 is done unidirectional orbiting motion in gathering sill.Positive stop spring plate 5 is contained in the openend of deck 2.Because the inside basic structure of deck 2 is prior art, innovative point of the present invention is provided with positive stop spring plate 5 at the openend of deck 2, and therefore, the concrete structure of deck does not remake very detailed giving unnecessary details at this.Fix through pcb board or FPC plate between deck and the housing.When drawer was not endured into deck, the front end of tuck was positioned at the former end points of gathering sill, shown in accompanying drawing 4.In addition, between drawer 3 and the deck 2, except with positive stop spring plate 5 and deck in the signal contact feet contact, all there is the gap in other each faces.

On drawer 3, place electronic cards 9, because drawer 3 is provided with the oblique angle, prevent that effectively electronics from putting back, the left and right sides of drawer is symmetrical set, but front and back are asymmetric, if because of carelessness drawer is instead inserted during use then can not be inserted and put in place, has played the effect that counnter attack is inserted.Drawer 3 both sides offer the draw-in groove 6 that matches with positive stop spring plate 5.

Shown in accompanying drawing 5, electronic cards 9 correctly is placed on the drawer 3, the through hole of offering drawer 3 on the housing 1 inserts and by on earth.Slide blocks 23 in the deck 2 receive the crowded of drawer 3 and are pushed to the bottom surface of the main body 25 of deck 2; The main body 25 interior springs 22 that are contained in deck 2 are compressed; Positive stop spring plate 5 receives the extruding generation deformation of drawer 3, and the front end that places the tuck 24 in slide block 23 gathering sills former end points in the gathering sill from the slide block 23 slides into the bottom righthand side of gathering sill.Because the leading section of drawer 3 is wideer than the through hole of offering on the spacing slide block 42, therefore, drawer 3 when advancing deck 2 because guarantee not can be by excessively by arriving in the deck 2 stopping of position limiting slide block 42.And the through hole on the housing 1 is slightly wideer than drawer; The front end portion of drawer is positioned at housing 1 through hole during by the extreme position that advances in the deck 2 with drawer 3; Position limiting slide block 42 receives the extruding of drawer 3 and moves simultaneously, and the limit spring 43 that is sleeved on position limiting slide block 42 two side arms is compressed.

Drawer 3 is loosed one's grip after on earth, and the drawer self-return also pins.Shown in accompanying drawing 6, the recovery elastic force of limit spring 43 forces position limiting slide block 42 outwards to slide.Be sleeved on spring 22 on the slide block 23 in the main body 25 of deck 2 owing to be in compressive state, restore concerning this moment, and spring 22 elastic force force slide block 23 to slide, and then promote drawer 3 and outwards move.Slide block 23 is in the process that outwards moves, and the bottom righthand side of the gathering sill of the top that drives tuck 24 from the slide block 23 slides to medium position left, thus the temporary transient medium position of hanging tightly at gathering sill, thus stop slide block 23 to continue outwards to move to withdraw from.But drawer 3 continuation under the promotion of position limiting slide block 42 is outwards withdrawed from, and when position limiting slide block 42 pushes up the inwall of housing 1, stops outwards to withdraw from, and the positive stop spring plate 5 in the deck 2 restores in the draw-in groove 6 that falls into the setting of drawer 3 dual-sides, stops drawer 6 to continue outwards to withdraw from.5 pairs of drawers of positive stop spring plate this moment 3 keep the power toward the interior top of card; Position limiting slide block 42 then keeps the power on a top outside deck 2 to drawer 3; Under the effect of these two kinds of power, drawer 3 is lockable on accurate position, thereby makes the front end face of drawer 3 keep concordant with the front end face of housing 1.This moment, drawer 3 was in the state of pinning.Electronic cards 9 is positioned at the optimum position of electronic circuit contact, and digital product is in the electronic working state.

When taking out electronic cards, in the time of promptly need drawer being taken out, only need drawer pushed to loose one's grip in the deck more again to get final product.Shown in accompanying drawing 7, drawer 3 is advanced in the deck 2 once more, because the gathering sill on the slide block 23 is unidirectional track, so tuck 24 superincumbent motions also are one-way movement, the top of tuck 24 continues to slide into left lower end left by original position that is positioned at the middle part.Spring 22 on the slide block 23 is compressed again.Loose one's grip then, shown in accompanying drawing 8, slide block 23 receives the reseting elasticity of spring 22 and is released outward, and up slide the left lower end of the gathering sill of the top of tuck 24 from the slide block 23, and falls into next ladder and tangle, and former endpoint location is got back in final operation.Because tuck 24 tops do not tangle slide block 23 sliding the process that falls into next ladder, so slide block 23 keeps outwards withdrawing from, simultaneously position limiting slide block 42 also produce pressure with drawer 3 toward extrapolation, slide block and position limiting slide block eject drawer together.Though the power of positive stop spring plate to pushing up in the still oriented deck of drawer, the thrust outward that this power is added up drawer is applied less than slide block and position limiting slide block, so drawer is ejected.So far, drawer is accomplished one and is packed, ejects push into---and the action of push, tuck 24 is also finally got back to former endpoint location again from the initial position of former end points is mobile, accomplishes a circulation.

The foregoing description is the utility model preferred implementation, need to prove, under the prerequisite of the inventive concept that does not break away from the utility model, any conspicuous replacement is all within protection scope of the present invention.
