Embodiment
See also Fig. 1, bolt lock mechanism 20 is applied to optical module 10, and can be with optical module 10 optionally in conjunction with being fixed on (not shown) on the electronic installation, please refer to Fig. 2 simultaneously, optical module 10 can be made of loam cake 11, circuit board 12 and lower cover 13, and bolt lock mechanism 20 includes pull bar 21, sliding part 22 and draw-in groove 23.Pull bar 21 is installed in optical module 10 front ends, and the body of rod that has rotation section 212 and extend downwards by 212 two ends, rotation section, and have the rotating shaft 213 of connection on the body of rod, and comprise at least more than one teat 211 in the rotating shaft 213, will cooperate funtion part to describe in detail in the back.
Sliding part 22 is made up of 221,222 of two sliding parts, and an end connects as one by connecting portion 223, and the other end respectively has a laterally projecting holding section 2211,2221.23 designs of draw-in groove are for the teat 211 of installing pull bar 21.
Wherein, pull bar 21 is installed in draw-in groove 23 and is incorporated into optical module 10 1 ends in rotating mode by teat 211, and sliding part 22 is held on the optical module 10, and can slide with respect to optical module 10, and is set on the pull bar 21.
Under normal conditions, see also Fig. 3 A and 3B, sliding part 221 because of sliding part 22,222 are held on optical module 10, and an end face of the teat 211 of pull bar 21 is against the reference field 231 of draw-in groove 23, the other end is then on an abutment wall of draw-in groove 23, shown in scheming is example, the transverse section of teat 211 can probably be one fan-shaped, and its two string is defined as the first contact end face 2111 and the second contact end face 2112 respectively, and the bottom surface of draw-in groove 23 is a reference field 231, when the first contact end face 2111 is resisted against reference field 231, the second contact end face 2112 can be resisted against on the abutment wall of draw-in groove 23, and when second surface of contact 2112 is resisted against reference field 231, promptly changes the first contact end face 2111 and be resisted against on another abutment wall of draw-in groove 23.At this moment, when teat 211 is resisted against reference field 231 with the first contact end face 2111, can make pull bar 21 and sliding part 22 be maintained at the position of normality, the holding section 2211,2221 of sliding part 22 then can be given prominence to and is sticked in (not shown) on the electronic installation, and this moment, because the first contact end face 2111 of teat 211 is resisted against reference field 231, can make module be maintained at this one in conjunction with fixing state and do not break away from electronic installation.
In case rotating tension bar 21, making pull bar 21 is axle with rotating shaft 213, and rotates with respect to optical module 10, can teat 211 be rotated interlock, and make the first contact end face 2111 break away from reference field 231 against state, see also Fig. 5 A and 5B.Therefore, under situation about being rotated further, teat 211 can be rotated further and make an abutment wall of the second contact end face conflict draw-in groove 23 and move to reference field 231 along this abutment wall, and become the second contact end face 2112 is resisted against reference field 231, this moment because the relative position of rotating shaft 213 away from, the horizontal relative position of pull bar 21 is moved, the sliding part 22 that related drive is sheathed on pull bar 21 outwards slides, and makes the holding section 2211,2221 of sliding part 22 break away from the stationary state that combines with electronic installation to front slide.
From the above mentioned, this invention cost simple in structure, that component count is few, relative is also cheap, and is easy to assembling.In addition, sliding part 22 does not limit two sliding parts 221 as shown in FIG., 222 design, also can be changed to sheet or single etc., holding section 2211,2221 is outwards outstanding about also not being defined as, equally also can be designed to up and down or the design of single holding section according to difformity, and the design of teat 211 on the rod shaft, as long as because the surface of contact of 23 of teat and draw-in grooves moves and makes the relative displacement of pull bar generation horizontal direction at draw-in groove 23, for example can be and have two teats 211 (as Fig. 6 A, 6B), or the transverse section summary forms teat 211 (as Fig. 6 C for circle rotating shaft 213 is incorporated into eccentric part, 6D), or the transverse section summary is square and rotating shaft 213 is incorporated into eccentric part and forms teat 211 (as Fig. 6 E, 6F), also or the reference field of draw-in groove has and a plurality ofly outstanding teat can be engaged (as Fig. 6 G with it, 6H).
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of claim of the present invention.
