Detailed description of the invention
As shown in Figures 1 to 6, a kind of child safety seat described in the utility model, including seat body 1, the safety belt assembly being installed in seat body 1, for safety belt assembly being locked in catch assembly in seat body, be used for the retracting device that furled by safety belt assembly.Described catch assembly include fixing with seat belt end the latch 2 being connected and for and the fastener 3 that coordinates of latch.Described fastener 3 is rotationally connected by rotating shaft and seat body 1, and described fastener 3 can rotate at the fore-and-aft direction of seat body 1.Described fastener 3 has the primary importance away from safety belt assembly and the second position near safety belt assembly, and described fastener 3 can carry out back rotation switching position between primary importance and the second position.Described child safety seat also includes can by the locking system of seat belt locking, described locking system is connected with fastener 3, and described locking system and fastener 3 link, when fastener 3 is in primary importance, described seat belt can freely be pulled out, and described retracting device can freely furl seat belt;When fastener 3 is in the second position, described locking system is by seat belt locking, and described seat belt is only capable of being furled by retracting device.
As shown in Figure 6, described locking system includes being installed in retracting device locking pedestal 4, locking steel ball 5 and the lockable mechanism (not shown) triggered by locking steel ball 5.The surface that upper face is indent of described locking pedestal 4, offers groove 6 in the lowest point of the upper surface of locking pedestal 4, and when locking steel ball 5 holder is put on groove 6, described seat belt can freely be pulled out, and described retracting device can freely furl seat belt;When locking steel ball 5 leaves groove 6 position, described locking steel ball 5 triggers lockable mechanism and is only capable of being furled by retracting device by seat belt described in seat belt locking, and namely seat belt cannot freely be pulled out.Lockable mechanism described in the present embodiment is existing common structure, does not launch to describe in detail herein.
As it is shown in figure 5, described locking system also includes being installed in outside retracting device near the fixing seat 7 of locking pedestal 4, the slide block 8 being slidably disposed on fixing seat 7 and the magnet 9 being fixedly installed on slide block 8.Described magnet 9 can near locking steel ball 5 or away from locking steel ball 5 under the drive of slide block 8, and described fastener 3 is connected with slide block 8 by hauling rope.Described fixing seat 7 is body structure, is internally provided with the guide rail 10 extended in left-right direction at fixing seat 7, and described slide block 8 is arranged on guide rail 10, and described slide block 8 can slide in left-right direction.When fastener 3 is in primary importance, slide block 8 is away from locking pedestal 4, and described magnet 9 is away from locking steel ball 5, and the holder of described locking steel ball 5 is put on groove 6;When fastener 3 is in the second position, slide block 8 is near locking pedestal 4, and locking steel ball 5 is attracted to leave groove 6 position by described magnet 9 near locking steel ball 5.
As shown in Figure 3, described safety belt assembly includes left shoulder belt 11, right shoulder belt 12, tail band 13 and three-way connector 14, described retracting device includes reel 15, described left shoulder belt 11 and right shoulder belt 12 set up separately in left-right direction in seat body 1, described left shoulder belt 11 and right shoulder belt 12 walk around that seat body 1 and three-way connector 14 is fixing to be connected, described tail is wound on reel 15 with one end of 13, and described tail is fixedly connected on three-way connector 14 with the other end of 13.
The work process of child safety seat described in the utility model is as described below: child is seated on child safety seat, and operator holds on the other hand latch 2 and pulls latch 2 and make seat belt pull out from the reel 15 of retracting device, the length of adjustment seat belt.Now, fastener 3 is in primary importance, and described magnet 9 is away from locking steel ball 5, and locking steel ball 5 holder is put on groove 6.Retracting device can freely furl seat belt, and namely seat belt both can be drawn out and also can have been furled.Then, rotate fastener 3, fastener 3 is made to be transformed into the second position from primary importance, such fastener 3 is slided towards near the direction of locking pedestal 4 with movable slider 8 by hauling rope, and then magnet 9 makes locking steel ball 5 leave groove 6 position near locking steel ball 5, locking steel ball 5 triggers lockable mechanism and makes retracting device locking seat belt, and seat belt cannot be drawn out retracting device again.Latch 2 is inserted in fastener 3 and is locked by seat belt by operator, and unnecessary seat belt can be automatic rolled up by retracting device, automatically adjusts the length of seat belt, and so far the process of wearing of whole seat belt completes.
Child safety seat described in the utility model is arranged by rotating of fastener 3 and is made the locking of seat belt can complete by rotating fastener 3 with slide block 8 and the magnet 9 of fastener 3 linkage.Making seat belt coordinate, by latch 2 and fastener 3, the locking simultaneously completing seat belt inserting locking, such operator can simply easily complete the operation that child is sitting on child safety seat wear safety belt.
As it has been described above, we are illustrated fully according to objective of the present utility model, but this utility model is not limited to above-described embodiment and implementation.The practitioner of correlative technology field can carry out different changes and enforcement in the scope that technological thought of the present utility model is permitted.
