The specific embodiment
Set forth preferred embodiment of the present invention below in conjunction with accompanying drawing 1-8 in detail
; Thereby protection scope of the present invention is made more explicit defining so that advantage of the utility model and characteristic can be easier to those skilled in the art will recognize that.
Among the embodiment of
the utility model; Shown in accompanying drawing 1-3; The connecting device of safety chair seats of car for children; Its with one be used for being connected with automobile the snap close 11 formation lockout mechanism that matches, this connecting device comprises housing 1, latch hook 2 with inner chamber, suspends part 3, connecting element 4, separates lock slide 5, stage clip 6 and torsion spring 7.
are shown in accompanying drawing 5; Latch hook 2 comprises axial region 21 with axis and the hook portion 22 that is used for blocking with snap close 11, the radial outward from the outer peripheral face of axial region 21 along axial region 21 convexes to form first protruding 211, second the protruding the 212 and the 3rd protruding 213; Preferably; First protruding 211, second protruding the 212 and the 3rd convexity 213 of latch hook 2 is towards the same side, and latch hook 2 can be around the axis rotation of axial region 21, and the hook portion 22 of latch hook 2 can connect and fix with snap close 11 or break away from mutually.The axial region 21 of latch hook 2 runs through second through hole 41 that inserts said first through hole 51 of separating lock slide 5, connecting element 4 rotationally, suspends in the third through-hole 31 of part 3.
connecting element 4 is fixedly installed in the cavity of upper casing and lower casing formation through connecting to pin.Shown in accompanying drawing 6, offer gain 42 in the connecting element 4, this gain 42 and second protruding 212 is complementary, and gain 42 allows latch hook 2 in its space, to rotate freely, but has limited the slip of latch hook 2 along fore-and-aft direction.
are suspended part 3 and are conciliate the both sides, front and back that lock slide 5 lays respectively at connecting element 4.
are shown in accompanying drawing 7; The trailing flank that suspends part 3 props up with the salient of snap close 11 mutually; Suspend part 3 and have the groove 32 that is used to hold the 3rd convexity 213; When lockout mechanism was in the lock state, the back cell wall that suspends the groove 32 of part 3 offseted at the rear side and the 3rd protruding 213 of the 3rd convexity 213 of latch hook 2, and third through-hole 31 connects and is opened on the back cell wall of groove 32.When the 3rd convexity 213 of front end face that suspends part 3 and latch hook 2 was separated, the 3rd protruding 213 of latch hook 2 inserted in the third through-holes 31, suspended part 3 this moment and can slide along fore-and-aft direction, further rotated but while third through-hole 31 has limited latch hook 2.Be provided with stage clip 6 between time-out part 3 and the housing 1, when this connecting device was in coupled condition, stage clip 6 was in compressive state, suspended part 3 and had the trend that slides backward.
The rear end that lock slide 5 is separated in
is positioned at the cavity of housing 1, separates cavity that the front end of lock slide 5 stretches out housing 1 to be connected with the automobile permanent seat.Shown in accompanying drawing 8, separate lock slide 5 and have the plug helix 52 that is complementary with first protruding 211, separate lock slide 5 and can slide along fore-and-aft direction, an end of torsion spring 7 is arranged on the axial region 21 of said latch hook 2, the other end of torsion spring 7 with separate lock slide 5 and link to each other.When connecting device was in off-state, torsion spring 7 was in twisting states, and latch hook 2 has the trend of contrarotation.Separate between lock slide 5 and the connecting element 4 and be provided with retracing spring 8, when connecting device was in released state, this reseting pressuring spring 6 was in compressive state, separated lock slide 5 and had the trend that slides backward.
when said lockout mechanism was in the lock state, the hook portion 22 of latch hook 2 caught on snap close 11, and latch hook 2 cooperate with housing 1 constitute one be used to locate snap close 11 the space, the 3rd protruding 213 of latch hook 2 inserts in the groove 32 that suspends parts 3; When said lockout mechanism was in released state, the hook portion 22 of latch hook 2 was left snap close 11, and the 3rd protruding 213 of latch hook 2 breaks away from the groove 32 that suspends part 3 and inserts in the third through-hole 31 that suspends part 3.
The principle of work of the utility model is following:
1, be in the lock state last time when connecting device is locked in automotive seat, stage clip 6 is in compressive state, and this moment, pulling was separated lock slide 5 to front slide; Plug helix 52 on it can act on first convexity 211 of latch hook 2, forces latch hook 2 rotations, and the torsion spring 7 of its afterbody is compressed along with the rotation of latch hook 2; When latch hook 2 rotates to certain angle, suspend part 3 and under the effect of stage clip 6, slide backward, the 3rd protruding 213 of latch hook 2 inserts in the waist hole of suspending part 3; Waist hole restriction latch hook 2 further rotates, and the hook portion 22 and the said snap close 11 of latch hook 2 are separated, at this moment; Under the restriction of limiting stopper 10, suspend part 3 and can not continue to slide backward.
, when connecting device is in released state; Stage clip 6 is in relaxation state; When separating lock slide 5 to front slide; Plug helix 52 drives said latch hook 2 and rotates to the 3rd protruding 213 of latch hook 2 around the axis of its axial region 21 and be separated with the end face of said time-out spare 3, and stage clip 6 orders about and suspends that part 3 slides backward so that the bayonet socket of the hook portion 22 of said latch hook 2 and said snap close 11 is separated; When the salient of said snap close 11 order about said time-out spare 3 to front slide so that the 3rd protruding 213 the contacting of said latch hook 2 with the end face of said time-out spare 3, torsion spring 7 orders about latch hook 2 rotates to latch hook 2 around the axis of its axial region 21 hook portion 22 and snap close 11 clamping mutually.
the utility model adopts above structure, compares the light easy hommization that has more of operation with other same device, and compact conformation is safe and reliable.
The front and back position mentioned in
above accompanying drawing relation is like accompanying drawing 2, shown in 3, after separating position that lock slide 5 is in and being, before the position that time-out part 3 is in is.
are above to combine diagram to be illustrated to specific embodiment of the present invention; But protection content of the present invention is not only limited to above embodiment; In affiliated technical field of the present invention; The common knowledge of GPRS just can be carried out diversified change in its technological main idea scope.
