Description

Improve ISOFIX interface connector

Affiliated technical field

The utility model belongs to child's safety seat for vehicle field, particularly a kind of ISOFIX interface connector that improves.

Background technology

ISOFIX interface is a kind of international child safety seat standard interface, and the child safety seat of being furnished with ISOFIX interface connector can be connected the child safety seat that is locked with the automotive seat with the corresponding interface.Formerly the utility model patent of the patent No. 201220211314.2 " a kind of child safety seat IOSFIX connecting device " discloses a kind of ISOFIX joint connecting structure, it comprises shell and establishes latch hook, slide block, connecting element and trigger bar in the inner and the parts such as spring, torsion spring, and its housing is by two involutory being spliced of side plate.When use, latch hook overcomes torsion spring pulling force and rotates, on latch hook recess rotate with latch hook and the projection of slip front coordinates and realizes locking, while unlocking, pull trigger bar band movable slider to retreat and make aforementioned projection depart from recess, the torsion spring promotion latch hook that resets goes back to original position.Although this connecting device can be realized can provide stable with comparatively simple structure, firmly ISOFIX interface connects, the installing component quantity of this connecting device is too much, and assembling is complicated, has further affected assembling speed and production efficiency.

Utility model content

The technical assignment of the technical problems to be solved in the utility model and proposition is to overcome number of components that patent formerly exists to assemble complexity more and cause assembling speed to affect slowly the technological deficiency of production efficiency, and a kind of improvement ISOFIX interface connector that can obviously reduce number of components, simplified structure and accelerate assembling speed is provided.

Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: improve ISOFIX interface connector, comprise the latch hook with fore shaft and recess in two involutory shells that are spliced into of side plate and shell, with protruding slide block, connecting element and trigger bar, on latch hook, cover has torsion spring and is rotationally connected with shell front end, connecting element is fixed in outer casing back, slide block is laterally slidably connected between latch hook and connecting element, trigger bar stretches out from outer casing back through connecting element, on connecting element, perforate wears trigger bar, on trigger bar, cover has spring, both ends of the spring withstands respectively connecting element and slide block, it is characterized in that the portable bar that described slide block and trigger bar are structure as a whole, slide block forms the sliding part of portable bar front end, trigger bar forms the release portion of portable bar rear end.By slide block and trigger bar being made of one to the portable bar of structure, slide block and trigger bar form corresponding sliding part and release portion, in reducing installation component, do not guarantee that adaptor union normally uses, and further simplify number of assembling steps, enhance productivity.Sliding part elasticity conflict latch hook rear end under action of the spring of portable bar front end when the utility model work, in the time that the utility model docks with ISOFIX interface, projection snaps in the recess on latch hook and realizes and locking; In the time that the release portion of portable bar rear end pulls back, slider end retreats thereupon, and projection departs from recess, and torsion spring band moveable lock hook rotates and resets.In addition, two blocks of side plates also need to rivet by pin while being spliced into shell fixing involutory, and latch hook is rotated and is installed on shell by locating dowel pin, is all prior art.

As further improving and supplementing technique scheme, the utility model adopts following technical measures: described connecting element is a perpendicular locating plate of putting connecting and fixing with shell, and the both sides of locating plate head on the side plate of homonymy and are clamped and fastened between biside plate.Locating plate utilizes self structure to be connected in the involutory shell being spliced into of biside plate and fixes with shell, does riveted joint location without additional parts, has reduced number of components, has simplified package assembly.

Described locating plate both sides, respectively along vertically extending upper and lower two cambered outwards positioning convex of horizontal stroke, have the jack with positioning convex coupling on two blocks of side plates.Two positioning convex up and down that distribute because locating plate both sides are vertical and the corresponding jack coupling on two blocks of side plates, just can clamp middle locating plate while being spliced into shell and realize the installation of locating plate and shell and fix when two blocks of side plates are involutory.

Contour guide protrusions is extended in described sliding part both sides, has corresponding horizontal chute on the side plate of guide protrusions homonymy.Sliding part utilizes the horizontal chute coupling on the extended guide protrusions in both sides and two side plates, guide the motion of spacing sliding part, as spacing in axle slides without increasing additional parts, horizontal chute coupling when work on the side plate of guide protrusions and homonymy, sliding part is played to position-limiting action, and guided slidable portion stably translational slides.

The guide protrusions of described sliding part both sides is respectively two and distributes along direction of slip, has the horizontal chute of quantity equity on the side plate of homonymy.Respectively establish the horizontal chute coupling of correspondence on two guide protrusions and homonymy side plate in the both sides of sliding part along direction of slip, the spacing sliding part motion of translation of guiding that can be more stable.

The utility model is made of one slide block and trigger bar the portable bar of structure, utilize the extended relevant work end that convexes to form in multiple parts self surface realize fixing or slide spacing simultaneously, obviously reduce number of components, simplified package assembly, further enhanced productivity.
