Embodiment

Reference picture 1 and Fig. 2, it is the embodiment of the device for ejecting 100 of this creation, Fig. 1 is schematic appearance, and Fig. 2 is local Decomposing schematic representation.Device for ejecting 100 be arranged on rack optical fiber case 200 inside, device for ejecting 100 to eject cassette disk 2, and The Fiber optic cassette 5 on cassette disk 2 is driven to exit, here, be assemblied in four optical fiber cassettes 5 on cassette disk 2, and at one Trilaminate structure is formed in optical fiber case 200, allows 12 optical fiber cassettes 5 to put.Device for ejecting 100 includes frame body 1, card Casket disk 2 and plural ejecting structure 3.

Reference picture 1 and Fig. 2, in the present embodiment, frame body 1 includes two tracks 11 and two blocks 13, and track 11 is by forward sight The general of sight is in ㄈ font outward appearances, and two tracks 11 claim toward each other and the both sides inside optical fiber case 200.Here, each block 13 It is located at each rear of track 11 respectively, also, each block 13 is prominent from each inner side of track 11 respectively, and each block 13 is after each track 11 It is square to be acted on into backstop wall.In addition, the front of each track 11 includes catching groove 111.

Reference picture 1 and Fig. 2, in the present embodiment, by the general U-shaped outward appearance of forward sight sight, cassette disk 2 is arranged at cassette disk 2 Between two tracks 11, in detail, the both sides of cassette disk 2 have each extended over side plate 21, and each side plate 21 slips into each track 11 respectively, separately Outside, the slotted eye 211 formed with corresponding each catching groove 111 on each side plate 21.

Reference picture 1 and Fig. 2, each ejecting structure 3 are an elongated plates, and each one end of ejecting structure 3 is respectively and fixedly connected with cassette disk 2 Both sides, each other end of ejecting structure 3 are extended with the shell fragment 31 of contact blocks 13, here, shell fragment 31 is by a length by overlook sight Stripe board extends to the bottom of > font structures, it is, shell fragment 31 includes affixed section 311 of elongated plate, from affixed section Supporting part 312 that 311 ora terminalis are tiltedly stretched outwardly, the rotation folding part 313 of turning point 313 and one of the turnover of self-supporting portion 312 are towards block The contact site 314 of 13 extensions, also, supporting part 312, turning point 313 and the inner side of contact site 314 form elastic space 32.

Reference picture 3 and Fig. 4, Fig. 3 are local overlooking schematic diagram when ejecting structure compresses, when Fig. 4 is that ejecting structure rebounds Local overlooking schematic diagram.When cassette disk 2 loads in the track 11 of frame body 1, shell fragment 31 extrudes block 13, shell fragment 31 Contact site 314 is relative with supporting part 312 to be compressed, and elastic space 32 diminishes, and in other words, shell fragment 31 supports block 13 and forms compression During distance P1（Compress shape）, cassette disk 2 is located in two tracks 11.When exiting cassette disk 2, shell fragment 31 discharges reaction force, Shell fragment 31 extrudes block 13, and the contact site 314 of shell fragment 31 is relative with supporting part 312 to be flicked, and elastic space 32 is expanded and becomes original again Come the size after flicking, in other words, shell fragment 31 supports block 13 and forms rebound distance P2（Expand shape）When, the front end of cassette disk 2 Eject outside two tracks 11, here, with the front end automatic spring of cassette disk 2, convenient use person holds the front end of cassette disk 2 and pulled it, And the power of this front end automatic spring of cassette disk 2 with apart from appropriate, the problem of avoiding wounding.

In addition, when shell fragment 31 is formed at compression distance P1, the first angle is formed between supporting part 312 and contact site 314 A1, when shell fragment 31 is formed at rebound distance P2, the second included angle A 2, the first angle are formed between supporting part 312 and contact site 314 A1 is less than the second included angle A 2, and the first included angle A 1 is essentially 90 degree, and the second included angle A 2 is essentially 120 degree.In addition, in some realities Apply in aspect, the first included angle A 1 can be 85 degree, 80 degree, 95 degree or 100 degree, and the second included angle A 2 can be 110 degree, 115 degree, 125 degree Or 130 degree.

Local overlooking schematic diagram when reference picture 5, Fig. 6 and Fig. 7, Fig. 5 are spring-piece type clasp buckle, Fig. 6 are spring-piece type button Local overlooking schematic diagram when hook presses, Fig. 7 are local overlooking schematic diagram when spring-piece type clasp ejects.In the present embodiment, bullet Go out device 100 and further include the plural formula clasp of shell fragment 31, each formula clasp of shell fragment 31 is an elongated plates, here, the formula button of each shell fragment 31 Hook is separately mounted to the both sides in the front of cassette disk 2, and each formula clasp one end of shell fragment 31 is respectively and fixedly connected with the side plate 21 of the both sides of cassette disk 2 On, each formula clasp other end of shell fragment 31 has each extended over the grab 41 of each track 11 of buckle and extended outside each track 11（Before Side outside）Press section 42.

Reference picture 5, Fig. 6 and Fig. 7, each grab 41 include leading oblique angle 411 and positioned at the backstop side for leading the side of oblique angle 411 End 412, it is in ∠ type outward appearances by overlooking the general of sight to lead oblique angle 411 with backstop side 412, forward slips into track 11 for cassette disk 2 and blocks Button, and then blocked by backstop side 412 when pulling out cassette disk 2 from front, it is necessary to grab 41 is pushed aside, grab 41 is departed from and rail The buckle in road 11, cassette disk 2 can be exited.

Although the utility model is disclosed above with embodiment, so it is not limited to the utility model, any affiliated Have usually intellectual in technical field, do not departing from spirit and scope of the present utility model, when can make a little change with Retouching, therefore the scope of protection of the utility model ought be defined depending on appended claims institute defender.
