The specific embodiment
Below in conjunction with above-mentioned accompanying drawing and adopt specific embodiment to be described in detail again the utility model.
As Fig. 1 ~ Fig. 8 shows, 1. base plate, 2. unlock piece, 3. down pressing seat, 4. upper pressure seat, 41. top indents, 5. interior fastener, 6. handle, 7. separate locking plate, 8. release rotation seat, 9. piston shelf, 91. is separated lock dogs, 10. piston spring, 11. release pistons, 12. slide block dead bolts, 13. stay bearing plates, 14. retracing springs, 15. latch bolt springs, 16. sports bars, 161. joint pins, 162. pushing tow inclined-planes, 17. recoil press springs, 18. safety belt for vehicle.
Base of children safety seat is in conjunction with hand basket release mechanism, and as shown in Fig. 1 ~ Fig. 3, Fig. 6 ~ Fig. 8, it is a kind of safe auxiliary mechanism that can facilitate base to be correctly installed on automotive seat, to realize removable jew installation hand basket again on base.The present embodiment is usingd the view left side of Fig. 2 and Fig. 3 as product rear portion, and view right side is described in detail as product front portion.
Described base both sides are respectively equipped with base plate 1, are provided with hard-wired stay bearing plate 13 between two base plates, and the front and rear of this stay bearing plate is equipped with the straight panel seat of upwardly extending disjunctor; Described two base plates 1 and stay bearing plate 13 all adopt hollowed-out board.
The rear straight panel seat of described stay bearing plate 13 is provided with handle 6 and upper pressure seat 4, and handle is positioned at the top of upper pressure seat, and these handle 6 leading sections and upper pressure seat 4 leading sections are all hinged on the straight panel seat of disjunctor of stay bearing plate 13.Simultaneously, between handle and 6 upper pressure seats 4, be also provided with fastener 5 in strip, the two ends of this interior fastener are hinged on respectively handle 6 middle parts and upper pressure seat 4 leading sections, therefore when handle rear portion is upwards pulled after rotation, can drive upper pressure seat 4 rear portions also upwards to rotate by interior fastener 5.
Described upper pressure seat 4 belows are provided with the down pressing seat 3 being fixed on stay bearing plate 13, can be used for installing and fixing safety belt for vehicle 18 between upper and lower wedge; Described upper pressure seat 4 bottom surfaces are provided with top indent 41; Described down pressing seat 3 is provided with mounting hole, in mounting hole, be provided with unlock piece 2 and be sleeved on the recoil press spring 17 on unlock piece 2, this unlock piece and bolt profile are similar, the two ends difference pushing tow of this recoil press spring 17 is on the interior shoulder of mounting hole and the outer shoulder of unlock piece 2 lower ends, therefore can make unlock piece 2 lower ends possess all the time a precompressed compression moving downward under the elastic force effect of recoil press spring 17; Unlock piece 2 upper ends are done to coincide equipped through the top indent 41 of mounting hole and upper pressure seat 4 bottom surfaces.When installing between upper and lower wedge after safety belt for vehicle 18, pull handle 6 downwards and just safety belt for vehicle firmly can be connected; , between unlock piece 2 upper ends and top indent 41, will be stopped by safety belt for vehicle 18 meanwhile, and move downward by safety belt for vehicle pushing tow unlock piece 2.
On described stay bearing plate 13, be also provided with before and after stay bearing plate and make axially movable sports bars 16 and slide block dead bolt 12, this sports bars is positioned at the below of down pressing seat 3, and slide block dead bolt 12 is positioned at the place ahead of sports bars 16; Described sports bars 16 rear ends are provided with pushing tow inclined-plane 162, this pushing tow inclined-plane contacts with unlock piece 2 lower ends, and recoil press spring 17 can make to remain best contacting between the pushing tow inclined-plane 162 of unlock piece 2 lower ends and sports bars 16, sports bars 16 front ends are provided with the joint pin 161 of a cylindrical shape; Described slide block dead bolt 12 rear ends are provided with a slotted hole, and joint pin 161 just in time active mounting in this slotted hole, therefore moving axially of sports bars 16 can be with movable slider dead bolt 12 to make synchronizing moving.
Described slide block dead bolt 12 1 sides are provided with latch bolt spring 15, this latch bolt spring is sleeved on a spring bar fixing with base plate 1, latch bolt spring 15 front end pushing tows are on slide block dead bolt 12, therefore this latch bolt spring as the retracing spring of slide block dead bolt 12, can make slide block dead bolt 12 possess all the time a propulsive effort moving forward under its elastic force effect.
Described slide block dead bolt 12 front end tops are provided with piston shelf 9, in piston shelf both sides, be respectively equipped with on one, the mounting hole of lower perforation, in each mounting hole, be equipped with piston spring 10 and release piston 11, this release piston is moved downward by piston spring pushing tow, at piston shelf 9 tops, arrange and separate lock dog 91 simultaneously, top rear is provided with rotates the release rotation seat 8 of installing, between this release rotation seat and stay bearing plate 13, be provided with retracing spring 14, the rotation of release rotation seat 8 is mainly to be controlled by the dipping and heaving of piston shelf 9, in the both sides of release rotation seat 8, be respectively equipped with a hard-wired solution locking plate 7, the top of this solution locking plate arranges interface for locking or the release of hand basket.
The utility model is mainly divided into lock-out state and released state.
Lock-out state is as Fig. 2, shown in Fig. 6, mainly refer to that safety belt for vehicle 18 is arranged on, between down pressing seat, now only need pull handle 6 downwards, through interior fastener 5, drive the relative down pressing seat 3 of upper pressure seat 4 to close up and push down safety belt for vehicle 18, this safety belt for vehicle will promote on pushing tow inclined-plane 162 that unlock piece 2 lower ends act on sports bars 16, and then actuation movement bar 16, slide block dead bolt 12 is motion backward simultaneously, the motion backward of this slide block dead bolt will cause release piston 11 to move downward, and piston shelf 9 also can form a space moving downward, while now carrying out again hand basket installation, the solution lock dog 91 at piston shelf 9 tops will move down and get out of the way installation site, thereby can not install to produce with hand basket, do not interfere, after hand basket is in place, release rotation seat 8 drives solution locking plate 7 to rotate and lock hand basket.This lock-out state only has to be put on when safety belt for vehicle 18, after upper and lower wedge compresses safety belt for vehicle 18 completely base is correctly installed on automotive seat, could realize the installation of hand basket, therefore safety in utilization is higher.
Released state is as Fig. 3 ~ Fig. 5, shown in Fig. 7, the desirable lower safety belt for vehicle 18 of the cocked handle 6 that makes progress, unlock piece 2 upper ends enter in top indent 41, the pushing tow inclined-plane 162 of sports bars 16 rear ends is no longer stressed, under the effect of latch bolt spring 15, be with movable slider dead bolt 12 reset that travels forward, and reenter piston shelf 9 belows, now the space that moves downward of release piston 11 and piston shelf 9 is blocked, when hand basket is wanted to install, the solution lock dog 91 at piston shelf 9 tops will produce and interfere with hand basket, thereby while making base correctly not be installed on automotive seat by safety belt for vehicle 18, hand basket just cannot be installed on base.
The above is only better embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
