Embodiment
A kind of ISOFIX chucks and its length adjustment mechanism of the invention are carried out below in conjunction with Figure of description further
Detailed description so that auditor can be more clearly understood from the present invention program.
As shown in Figure 1, Figure 2 and Figure 3, a kind of ISOFIX chucks, including the housing being spliced into by two pieces of side plate pairings, are set
Latch hook main body 25, positive stop strip 26, inserted sheet 23, locking extension spring 24, spacing extension spring 27 and release button 21 in housing；Wherein,
Latch hook main body 25 is rotationally connected with housing forward end, and the latch hook main body includes fore shaft 251, convex teeth portion 252 and recess 253, housing
The rear portion for being internally located at the latch hook main body 25 is respectively equipped with positive stop strip 26 and inserted sheet 23, and positive stop strip 26 is provided with and the double wedge
The intermeshing tooth-strip part 264 in portion；
Described one end of locking extension spring 24 is fixedly connected in inner walls, and the other end is connected with the inserted sheet 23, described to insert
Piece is contradicted with the latch hook main body 25 under the pretightning force of locking extension spring 24 and is connected, and the other end of inserted sheet 23 is fixedly connected described release
Put button 21；
Described one end of spacing extension spring 27 is fixedly connected in inner walls, and the other end is connected with the positive stop strip 26.
The positive stop strip 26 is arranged at below enclosure interior, and the inserted sheet 23 is arranged above enclosure interior, the housing
Inside is further respectively had for guiding the positive stop strip 26 and inserted sheet 23 in the housing inner diameter to the first mobile limited post
261st, the second limited post 231.
The inside locking process of ISOFIX chucks of the present invention is：
It is pressurized when the fore shaft of latch hook main body 25 is in the loading corresponding ISOFIX anchor points of automobile, latch hook main body 25 rotates,
The convex teeth portion of latch hook main body 25 drives the positive stop strip 26 to be moved to the left by being engaged with the upper rack portion 264 of positive stop strip 26, simultaneously
Inserted sheet 23 is by the pulling force of locking extension spring 24, and in the recess 253 for resetting insertion latch hook main body 25, release button 21 follows reset, real
Existing green display, so that, latch functions are realized, now ISOFIX chuck lockings.
ISOFIX chucks ISOFIX of the present invention discharges process：
Release button 21 is pulled back, inserted sheet 23 is driven, inserted sheet 23 is exited from the recess 253 in latch hook main body 25, by
Positive stop strip 26 is set to produce thrust in the reset strength of spacing extension spring 27, the rotate counterclockwise of latch hook main body 25 is opened.
As shown in Fig. 4 ~ Fig. 9, the present invention further discloses a kind of ISOFIX chucks length adjustment mechanism, is arranged on
Outside ISOFIX chucks, including：
FIX connecting tubes 16, for being connected with seat body；
Two balladeur trains at the two ends of FIX connecting tubes 16 are symmetrically fixed on, slides and is provided with respectively in each balladeur train
Tooth form chute is had on one ISOFIX chuck 18, the side wall of two balladeur trains, the two ends of a chuck connecting tube 28 are worn
Cross after the tooth form chute and be connected respectively with two ISOFIX chucks 18；
Each ISOFIX collet interiors are equipped with a locking member being engaged with the tooth form chute, the locking member
For a connecting rod, one end of the connecting rod is rotatably connected on ISOFIX chuck inwalls, and the other end has one to stretch out the ISOFIX
The bending part 221 of collet envelope；The top of bending part 221 is connected with one end of a stage clip 29, the other end of stage clip 29 and ISOFIX
Chuck inwall is connected, and the positive stop strip 26, provided with two contact surfaces with difference in height, is the first contact surface 262 and the respectively
Two contact surfaces 263, when the bending part 221 is in contact with first contact surface 262, the bending part 262 is plugged in institute
State in the tooth form chute on carriage side wall, when bending part 221 is in contact with second contact surface 263, the bending part 221
Leave the tooth form chute on the carriage side wall.
Further, the bottom and upper segment of the bending part 221 is arranged with two projections, is upper raised 222 He respectively
Lower convexity 223, is socketed the stage clip 29 on described raised 222, the lower convexity 223 is fastened on the outside of the tooth form chute
On wall.
Further, the tooth form chute includes the multiple pointed tooth portions of a row, each pointed tooth portion by positioned at pointed tooth
First hypotenuse of portion side and the second hypotenuse of opposite side are constituted.
Length adjustment principle is after ISOFIX chucks locking of the present invention：
As shown in fig. 7, after ISOFIX lockings, positive stop strip 26 is moved, and under the pretightning force effect of stage clip 29, locking member 22
Because stage clip 29 is acted on, downwards, bending part 221 coordinates locked in tooth plate tooth-shape structure with the tooth form chute on balladeur train, as general
Tooth plate is moved toward X-direction, because the elastic compression of stage clip 29 is acted on, locking member bending part 221 below with the in tooth form chute
The relative motion of one hypotenuse 171, i.e. ISOFIX chucks contraction in length；
Moved when by tooth plate toward y directions, now, the back side of the second hypotenuse of tooth plate 172 and locking member 22 is withstood, in stage clip 29
Pretightning force effect under, locking member 22 is all the time by the downward power of Z-direction, and locking member 22 is all the time with respect to the Impact direction of tooth plate 17
Downwards, so tooth plate 17 is withstood by locking member 22 to move, i.e., after body IOSFIX chuck lockings, ISOFIX chucks can not
Elongation.
As further preferred scheme of the invention, formation angle a, described second between first hypotenuse and horizontal plane
Angle b is formed between hypotenuse and horizontal plane, does not occur phase in order to ensure the second hypotenuse of tooth plate 172 is withstood with the back side of locking member 22
To motion, wherein, the angular range of the angle a is：0 ~ 45 degree, the angular range of the angle b is：45 ~ 90 degree.
After ISOFIX chucks of the present invention discharge, i.e., release button 21 is pulled back, drive inserted sheet 23, make inserted sheet 23 from lock
Recess 253 in hook main body 25 is exited, because the reset strength of spacing extension spring 27 makes positive stop strip 26 produce thrust, latch hook main body 25
Rotate counterclockwise is opened.Meanwhile, the second contact surface on positive stop strip 26 is in contact with the bending part on locking member 22, locking member 22
Be elevated so that the bending part of the locking member 22 leaves the tooth form chute on the tooth plate 17, ISOFIX chucks and balladeur train it
Between can relatively move, and now ISOFIX chucks arbitrarily can be forward moved rearwards by with two-way.
Further, as the prioritization scheme of the present invention, one end of the balladeur train is provided with baffle plate, the chuck connecting tube
Provided with fixed support, one end of a regulation extension spring is connected with the baffle plate, and the other end is connected with the fixed support.Drawn in regulation
Under the pulling force of spring, chuck connecting tube is pulled and is fixed on the baffle plate, now, and chuck is in most long position.
