Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
With reference to Fig. 2 to Fig. 6 is the utility model one embodiment, specifically comprises computer housing casing side plate 10, a plurality of card article 20 of exhibition plug-in unit and locking part 30 that is used for these card articles of snap close of protecting afterwards, and this locking part 30 slidably is set on the back side panel 10.
Wherein, this locking part 30 includes the basic portion 31 of a rectangular sheet, this basic portion 31 is used to compress all card articles that need snap close 20, better compresses effect for reaching, and is better than most in this basic portion 31 to be convexly equipped with a projection 311 that directly contacts with each card article 20 corresponding to each card article place.
Be outward extended with a T shape slide block 32 perpendicular to its basic portion 31 on this locking part 30, be provided with a T shape slideway 11 in back side panel 10 accordingly, this T shape slide block 32 is flush-mounted in this T shape slideway 11, be clearance fit slidably between T shape slide block 32 and the T shape slideway 11, thereby make this locking part 30 on back side panel 10, to slide.Be positioned at the both sides of this T shape slide block 32, respectively be outward extended with an elastic arm 33 perpendicular to matrix part 31 equally, one side of the tail end of elastic arm 33 convexes with a fixture block 34, and further the opposite side in the tail end of elastic arm 33 is extended with a motion arm 35 perpendicular to this elastic arm 33.
On the back side panel 10 apart from card article 20 from the near to the remote, spacing is provided with two parallel first draw-in groove 12 and second draw-in grooves 13 successively, when the fixture block 34 on the elastic arm 33 on the aforementioned locking part 30 snaps in this first draw-in groove 12 and second draw-in groove 13 respectively, form two kinds of duties of the snap close/release of locking part 30 respectively.
With reference to Fig. 5, when locking part 30 is in the snap close state, the basic portion 31 of this locking part 30 slides to the position near card article 20, and compress all card articles 20, this moment, described fixture block 34 inlay cards were gone near in first draw-in groove 12 of card article position, reached to prevent that locking part 30 from moving and loosening snap close to card article 20 towards the direction away from card article 20.
With reference to Fig. 6, when taking off card article 20 when wanting release, stir the motion arm 35 on the locking part 30, utilize the elastic deformation of the elastic arm 32 of locking part 30, impel this fixture block 34 to deviate from first draw-in groove 12, follow outside slide lock firmware 30, when this fixture block 34 slides to apart from more a little further second draw-in groove, 13 places of card article 20, elastic arm 33 utilizes the elasticity of himself and automatic fastening is gone in second draw-in groove 13, and this moment, this locking part 30 was in its released state, and promptly card article 20 is the state of detachable.
After the assembling or dismounting of the card article of finishing expansion plugin, stir the motion arm 35 on the locking part 30 once more, utilize the elastic deformation of the elastic arm 33 of locking part 30, impel this fixture block 34 to deviate from second draw-in groove 13, follow inside slide lock firmware 30, when this fixture block 34 slides to apart from more nearer first draw-in groove, 12 places of card article 20, elastic arm 33 utilizes the elasticity of himself and automatic fastening is gone in first draw-in groove 12, this moment, this locking part 30 was in its snap close state (with reference to Fig. 5), and promptly the card article 20 of respective extension plug-in unit is locked.
Emphasis of the present utility model is, replaced the snap close mode of the screw of tradition to card article by locking part, realized exempting from tool operation on the one hand, for the dismounting of expansion plugin is provided convenience; This locking part can a plurality of card articles of disposable snap close on the other hand, improve the dismounting efficient of card article greatly, and then save dismounting man-hour, save cost, improve the market competitiveness.
The above only is the preferred embodiment of buckle structure of the card article of a kind of expansion plugin of the utility model, is not that technical scope of the present utility model is imposed any restrictions.So every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
