It is a kind of simple in structure, reliable that the purpose of this utility model is to provide, the draw-ring type unlocking structure on the SFP module of processing ease.
For achieving the above object, the utility model adopts following technical scheme:
Draw-ring type unlocking structure on the SFP module comprises that base, a draw ring, a lever of a SFP module colludes, a pressing plate and a deck; The base of SFP module has an assembling end; Draw ring has Handheld Division and drive division, and drive division is assembled on the assembling end of base; The end that lever colludes forms a gib head, and the other end is a drive end, and drive end contacts with the drive division of draw ring, and the stage casing that lever colludes is articulated in the assembling end of base; Pressing plate is assembled on the assembling end of base, draw ring and lever is colluded position connection; Deck clamping base is provided with the button hole of the gib head snapping that can collude with lever on deck.
Gib head end that colludes at lever and drive end place are provided with a top spring respectively, and two top spring action levers collude and guarantee the gib head snapping deck that lever colludes.
The assembling end of base is provided with a groove, and the sidewall in the groove relevant position is provided with bearing pin groove extending transversely, and the both sides, stage casing that lever colludes are provided with the bearing pin of evagination, and bearing pin is assembled in the bearing pin groove on the base assembling end, and lever colludes the then local groove that embeds.
Described draw ring is the ring body of a sealing.
The utility model adopts package assembly, and the one-step optimization structure of going forward side by side makes assembling, dismantles more conveniently, and simple in structure, and the processing and fabricating cost is low; Also suitably be provided with a top spring in structure, collude the effect that automatically resets to reach lever, it is quite convenient to operate, and reliable operation.

Embodiment:
Understand for the juror can be had purpose, feature and the function of the utility model further, lift preferred embodiment now and cooperate graphic being described in detail as follows:
Please consult Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4 earlier, it is the structural representation of the preferred embodiment of the utility model, draw-ring type unlocking structure on the relevant a kind of SFP module of the utility model comprises that base 2, a draw ring 1, a lever of a SFP module colludes 5, one pressing plate 7 and a deck 4; The base 2 of SFP module has an assembling end 21, and the assembling end 21 of base is provided with a groove 211, and the sidewall in the groove relevant position is provided with bearing pin groove 212 extending transversely.Draw ring 1 is the ring body of a sealing, has Handheld Division 11 and drive division 12, and drive division 12 activities are assembled on the assembling end 21 of base, makes the draw ring 1 can be relative to rotating of pulling out and regain.Lever colludes an end of 5 and forms a gib head 51, the other end is a drive end 52, drive end 52 contacts with the drive division 12 of draw ring, during assembling, drive end 52 rides on the drive division 12 of draw ring relatively, drive division 12 correspondence positions of draw ring are bent to form a shoulder 121 relatively, but the ejection lever colludes 5 drive end 52 and moves upward when shoulder 121 rotates.The both sides, stage casing that lever colludes are provided with the bearing pin 53 of evagination, and bearing pin 53 is assembled in the bearing pin groove 212 on the base assembling end, form the assembling end that stage casing that lever colludes is articulated in base, and lever colludes 5 local grooves 211 that embed, and adopts and is pressed into assembling, and is convenient, fast.Pressing plate 7 is assembled on the assembling end 21 of base, fixes by screw 8 interlockings, is covered on the assembling end 21, thereby realizes that 7 pairs of draw rings 1 of pressing plate and lever collude 5 and position connection.Deck 4 clamping bases 2 are provided with the button hole 41 of gib head 51 snappings that can collude with lever on deck 4.
Shown in Figure 1, gib head end that colludes at lever and drive end place also are respectively equipped with 3,6, two top springs of top spring, 3,6 effect levers and collude 5 and guarantee the gib head 51 snapping decks (being that gib head 51 is tilted upward shown in the figure) that lever colludes.Certainly, this structure also can adopt effect levers such as torsion spring, shell fragment to collude 5, thereby obtains gib head 51 automatically reset effects, guarantees that also its snapping is more reliable, stable.
With reference to Fig. 2, shown in Figure 3, under normal condition, lever colludes 5 under the effect of spring 3 and 6, and lever colludes the surface that 5 front end gib head 51 can exceed deck 4, reaches to buckle into button hole 41, realizes that the module and card seat connects.Its course of work is as follows: when the SFP module is inserted deck 4, lever colludes 5 front end gib head 51 pressurizeds and extrusion spring 3 downwards, when lever colludes 5 front end gib head 51 and arrives the position, hole of decks 4, the gib head 51 that lever colludes can stretch out the surface of deck 4 under the effect of spring 3 and 6, thereby catches on deck 4.With reference to shown in Figure 4, if desired when 4 li of decks are extracted the SFP module, catch 11 backs, Handheld Division outwards to spur draw ring 1 earlier, the drive division 12 of draw ring 1 relatively rotates, shoulder 121 on the drive division 12 can drive levers and collude 5 drive end 52 and move upward, and colludes 5 stage casing bearing pin 53 by lever and is fulcrum, drives lever and colludes 5 front end gib head 51 and move downward, when lever colludes 5 51 ends of gib head in the plane of deck 4 and when withdrawing from button hole 41, just can extract the SFP module.
