Description
Technical field
The present invention relates to a kind of buckle for child safety car seat, be specifically a kind of for automotive child safety belt plug pull out button.
Background technology
Along with the raising day by day of living standard, family buys automobile and increases, and trip of driving is more and more, and children riding ratio increases, and ensures that child seats is safely problem in the urgent need to address.In order to improve the security of children riding, usually on automobile, safety seat is set up, by safety buckle, children are fixed in safety seat, the safety buckle general structure that orthodox car children's seat uses is complicated, and assembly is more, in the fastening locking and release release process of safety buckle, each assembly interlock is loaded down with trivial details, fasten intensity and security performance low, safety buckle easily comes off, and children riding exists potential safety hazard.
Summary of the invention
In order to solve children's armchair safety button complex structure in prior art, assembly is many, link during use loaded down with trivial details, fasten intensity low, easily come off, there is the deficiencies such as potential safety hazard, the invention provides a kind of structure simple, compact, assembly is few, make, easy to assembly, cost is low, during use, interlock is simple, fastening is stable, intensity is high, difficult drop-off, the buckle for child safety car seat that security performance is high.
The technical solution used in the present invention is: a kind of buckle for child safety car seat, and comprise an eye-splice and two inserted sheets, two inserted sheets are symmetrical arranged merging and plug together eye-splice, and its technical characterstic is the inserting-plate hole that described inserted sheet is provided with along plugging together direction; Described eye-splice comprises upper cover, button, sheet spring, stage clip, latch hook, cover plate and lower cover, described cover plate, latch hook, two stage clips, briquetting and sheet spring are in upper cover encapsulation lower cover, described two stage clip symmetries are fixedly installed in lower cover, latch hook lower surface is supported on two stage clips, the upper surface of latch hook is arranged with two locking platforms, and the height of locking platform increases gradually along plugging together direction; Described spring direction to be arranged at below latch hook and to be fixedly connected in lower cover through briquetting plugging together, and the two panels reed of sheet spring is plugging together corresponding two locking platforms on direction respectively; Described cover plate support is in latch hook upper surface, and that leaves corresponding two inserted sheets between cover plate with latch hook plugs together space; Described button is arranged at and covers with cover plate is corresponding stitching state.
Further, the both sides upper surface of described latch hook is arranged with two lugs, described cover plate is arranged with two locating holes, and the lower surface center of cover plate arranges a support column, and cover plate two locating hole correspondence is through two lugs, and cover plate is supported in latch hook upper surface through support column.
Further, described cover plate bottom be provided with eyelet; Described inserted sheet is provided with eyelet.Eyelet facilitates cross-under safety belt, is applicable to each position safety belt snapping and uses.
Again further, described locking platform is less than or equal to inserting-plate hole in the length plugging together direction and is plugging together the length in direction.Locking platform can be stablized and snaps in inserting-plate hole, and guarantee to pull out button and plug together reliable lock, stable, locking, anticreep, improves usage safety performance.
Pull out button when plugging together, advanced along plugging together direction by two inserted sheets, two locking platforms on pressing latch hook make locking platform overcome stage clip decline, when the inserting-plate hole of inserted sheet plugs together above locking platform, latch hook makes locking platform rising correspondence snap in inserting-plate hole the tight fastening realizing inserted sheet and eye-splice under stage clip effect, and now inserted sheet holds out against two reeds of sheet spring; Pull out button when extracting, button press, cover plate presses down latch hook along lug direction through support column, and latch hook overcomes stage clip and declines, and locking platform deviates from inserting-plate hole down mutually, and inserted sheet ejects the automatic disengagement realizing inserted sheet and eye-splice under the effect of sheet spring reed.
Inserted sheet of the present invention and eye-splice adopt the flexible clamping between inserting-plate hole and locking platform to lock and elasticity deviates to realize plug function, and this pulls out, and buckle structure is simple, and STATEMENT OF FEDERALLY SPONSORED is few, make, easy to assembly, sealed reliable, stable, locking, anticreep, and use safety, life-span are long.
Accompanying drawing explanation
Fig. 1 is external structure schematic diagram of the present invention;
