A kind of two-way blasket type safety seat anti-splashing thing safety guard mechanismTechnical field
The present invention relates to a kind of child safety seat, be specifically related to a kind of two-way blasket type safety seat anti-splashing thing safety guard mechanism.
Background technology
Existing child safety seat generally uses seat belt restraint device and flexible package that the child on seat is carried out buffer protection.But when there is sharp impacts, can produce in glass and car the splashes such as object, the child on seat can be damaged by splash.
Summary of the invention
It is an object of the invention to provide a kind of two-way blasket type safety seat anti-splashing thing safety guard mechanism.
The technical scheme that the present invention takes is:
A kind of two-way blasket type safety seat anti-splashing thing safety guard mechanism, tarpaulin strut including gate rack-like, tarpaulin push rod, tarpaulin, connecting rod and lower slide-bar, the middle and lower part of described tarpaulin push rod is installed on a left side for hand basket skeleton by bolted splice, the inner side of right plate, the two ends of tarpaulin strut also by bolted splice in tarpaulin push rod with left, between the inner side of right plate, the epimere of tarpaulin push rod is provided with the hook and slot in hand basket front, described hook and slot coordinates with two curb girders of tarpaulin strut, one end of described connecting rod is articulated with lower slide-bar, the other end of connecting rod is articulated with the lower end of tarpaulin push rod, one end of described tarpaulin is connected to tarpaulin strut, the tarpaulin other end is fixed on a left side, right plate；The two ends of described lower slide-bar are connected to the kidney slot on left and right side plate Nei and slide anteroposterior in kidney slot.
Further, being provided with handle between described left side plate, handle top cross-bar is provided with balancing weight, and tarpaulin strut is detachable with handle to be connected.
Further, left and right side plate being separately installed with elastic damping mechanism, described elastic damping mechanism is connected with the end of lower slide-bar
Yet further, described elastic damping mechanism includes throw-out lever, stage clip and fixing seat, described fixing seat is installed on side plate interior sides and rotates on side plate, the head of throw-out lever is articulated with slide-bar or the end of lower slide-bar, the afterbody of throw-out lever is connected to fixing seat, and described stage clip is squeezed between the head of throw-out lever and fixing seat.
After taking above technical scheme, the invention have the benefit that tarpaulin push rod is linked with lower slide-bar by connecting rod, when installing dorsad, after colliding, lower slide-bar moves forward in the drive of people and seat board, pulls connecting rod, and connecting rod drives tarpaulin push rod to rotate, tarpaulin push rod drives tarpaulin strut to rotate, and opens tarpaulin and prevents from splashing；When forward is installed, after colliding, handle adding inertia due to counterweight, handle rotates forward, drives tarpaulin strut rotating opening tarpaulin forward by dismountable connection, prevents the injury of splash.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the schematic diagram that tarpaulin is opened.
Detailed description of the invention
Below in conjunction with accompanying drawing, the detailed description of the invention of the present invention is further described:
As shown in the figure, a kind of two-way blasket type safety seat anti-splashing thing safety guard mechanism, tarpaulin strut 1 including gate rack-like, tarpaulin push rod 2, tarpaulin 3, connecting rod 4 and lower slide-bar 5, the middle and lower part of described tarpaulin push rod is by the hinged left side being installed on hand basket skeleton of bolt 6, the inner side of right plate 7, the two ends of tarpaulin strut 1 are also articulated with tarpaulin push rod 2 with left by bolt 6, between the inner side of right plate 7, the epimere of tarpaulin push rod 2 is provided with the hook and slot 8 in hand basket front, described hook and slot 8 coordinates with two curb girders of tarpaulin strut 1, one end of described connecting rod 4 is articulated with lower slide-bar 5, the other end of connecting rod 4 is articulated with the lower end of tarpaulin push rod 2, one end of described tarpaulin 3 is connected to tarpaulin strut 2, tarpaulin 3 other end is fixed on a left side, right plate 7；Slide anteroposterior in kidney slot that the two ends of described lower slide-bar 5 are connected on left and right side plate 7 front end 9 and in kidney slot 9, the back segment of left and right side plate 7 is provided with same kidney slot, in kidney slot, cross-under has upper slide-bar 15, the seat board 16 of upper and lower slide-bar cross-under cradle, slide-bar 5 under people is driven by seat board when colliding, lower slide-bar 5 drives tarpaulin push rod 2 to rotate by connecting rod 5, and tarpaulin push rod 2 drives tarpaulin strut 1 to open tarpaulin anti-splashing.Being provided with handle 10 between left side plate 7, described handle 10 top cross-bar is provided with balancing weight 11, and tarpaulin strut 1 is connected by thread gluing 16 is detachable with handle 10.Elastic damping mechanism it is separately installed with on left and right side plate, described elastic damping mechanism includes throw-out lever 12, stage clip 13 and fixing seat 14, described fixing seat 14 is installed on each side plate interior sides and rotates on side plate, the head of throw-out lever 12 is articulated with slide-bar or the end of lower slide-bar 5, the afterbody of throw-out lever 12 is connected to fixing seat 14, and described stage clip 13 is squeezed between the head of throw-out lever 12 and fixing seat 14.
