The specific embodiment

To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.

As Fig. 1 ~ shown in Figure 7,1. infant car seat, 11. handles, 12. anchor shafts, 2. base, 21. inner rips, 22. disjunctor projections, 3. installing mechanism, 31. lock hooks, 311. locked grooves, 32. globoidal structures, 33. springs, 34. tie rods, 35. extension springs, 36. drag hooks, 361. hook grooves, 362. opening grooves, 37. pull part, 371. boss.

The installing mechanism of infant car seat as Fig. 1 ~ shown in Figure 5, mainly is installed between infant car seat 1 and the base 2, is used to realize that the removable jew of the relative base of infant car seat connects.Handle 11 is equipped with at described infant car seat 1 top, conveniently lifts and carries, and the bottom is provided with a horizontally disposed anchor shaft 12 of broad ways; Front side, infant car seat 1 bottom is provided with drag hook 36, this drag hook middle part is hinged with infant car seat 1, connecting bore is extended in drag hook 36 upper ends, and extension spring 35 1 ends in this connecting bore, have been linked, the extension spring other end directly links in the connecting bore set on infant car seat 1, so make drag hook 36 relative infant car seats 1 form a pretension through this extension spring 35; Drag hook 36 lower ends are provided with crooked hook groove 361, and this hook groove links on the disjunctor projection 22 of base 2, and hook groove 361 next doors are provided with opening groove 362, and simultaneously, the bottom design of drag hook 36 is smooth globoidal structure 32.

Described base 2 is on the seat of the firm tighten of safety strap (not shown) at automobile, and these base 2 end faces are provided with the inner cavity of laying for infant car seat 1.Described installing mechanism 3 is installed in the above-mentioned inner cavity, this installing mechanism such as Fig. 6, shown in Figure 7, and it comprises two lock hooks 31 that are positioned at base 2 and is exposed at of base front side outward and pulls part 37.The structure of two lock hooks is identical, and its material is a steel, and intensity is good, and is harder, and just in time is positioned at over against the base 2 at anchor shaft 12 two ends.With one of them is that example is described in detail, these lock hook 31 middle parts are hinged in the base 2 with pin, the lock hook upper end is provided with and bends to hook-shaped locked groove 311, this locked groove and anchor shaft 12 can make snap lock or disengaging is opened, lock hook 31 top design are smooth globoidal structure 32, are beneficial to anchor shaft 12 and enter locked groove 311 fast and make snap lock; Lock hook 31 lower ends are provided with connecting bore.

Described part 37 middle parts that pull are hinged in the base 2, pull the part upper end and are provided with upwardly extending boss 371, and this boss is in direct contact with in the opening groove 362 of drag hook 36 lower ends; Pull part 37 lower ends and also be provided with connecting bore, and between the connecting bore of lock hook 31 lower ends and the connecting bore that pulls part 37 lower ends, be provided with the tie rod 34 that is connected, the end that this tie rod connects lock hook 31 directly is divided into two, and is connected with two lock hook 31 lower ends respectively.Two tie rod that is divided into two 34 outer springs 33 that all are set with, this both ends of the spring difference pushing tow is on the inner rip 21 of lock hook 31 and base 2.

The utility model mainly carries out snap lock by 3 or disengaging is opened, it is respectively the locking of two lock hooks 31 and anchor shaft 12, on drag hook 36 and the base 2 disjunctor projection 22 link locking, so infant car seat 1 relative base 2 installations lock more solid and reliable.Its snap lock state as shown in Figure 2, be two lock hooks 31 that the anchor shaft 12 of infant car seat 1 bottom is aimed on the base 2, the disjunctor projection 22 that drag hook 36 is aimed on the base, after globoidal structure 32 that anchor shaft 12 touches globoidal structure 32, drag hook 36 bottoms at lock hook 31 tops touches disjunctor projection 22, continue to install infant car seat 1 downwards, then anchor shaft 12 moves along the globoidal structure 32 at lock hook top, and pushing tow lock hook 31 overcomes spring 33 elastic force and rotates, in anchor shaft 12 enters locked groove 311 till; And drag hook 36 also overcame extension spring 35 elastic force and linked on disjunctor projection 22 this moment, and after infant car seat 1 and base 2 were in place, spring 33 resetted with extension spring 35 and can make infant car seat 1 relative base 2 enter the coupled condition of snap lock.

Infant car seat 1 breaks away from the state opened as shown in Figure 3 from base 2, one hand is upwards pulled and is pulled part 37 rotations, pull part upper end this moment and be in direct contact with in drag hook 36 lower ends boss 371 in the opening groove 362 and just can promote drag hook 36 and overcome extension spring 35 elastic force and rotate, and make disjunctor projection 22 disengagings of hook groove 361 from the base 2 on the drag hook.Meanwhile, in finishing above-mentioned course of action, tie rod 24 is also followed the rotation that pulls part 37 and is spurred two lock hooks 31 synchronously forward, and make two lock hooks all overcome the rotation of spring 33 elastic force, after rotating, these two lock hooks can make of anchor shaft 12 disengagings of the locked groove 311 of lock hook from infant car seat 1.Above-mentioned two operating process that action is synchronous interaction, when the hook groove 361 of drag hook 36 breaks away from the disjunctor projection 22 of base 2, the locked groove 311 of two lock hooks 31 also breaks away from anchor shaft 12 synchronously, so infant car seat 1 can be unloaded from base 2 fast, operating process is quick, laborsaving.
