The two ends of trailing wheel connecting tube 91 are provided with the spacing post holes 912 corresponding with stopper slot 812, and middle part is provided with and installation screw
811 corresponding openings 911.
Referring to Fig. 1 to Fig. 4, in assembling is constituted, yi word pattern projection 73 is located in yi word pattern groove 813 and constitutes brake lever
8 and the transmission connecting mechanism between slanted kicking block 7 is rotated, can improved to the diametrically fault freedom of alternate position spike between the two；Guide rod portion
51 insertion guide holes 70 are interior and can be moved along the axial reciprocating of guide hole 70；The pin 6 that brakes is located in barrel chamber 50, one end of spacer pin 43 according to
It is secondary to pass through a long through-hole 53, axis hole 61 and another long through-hole 53, and buffer spring 42 one end against barrel chamber 50 bottom hole wall, separately
One end against brake pin 6 end face, its elastic restoring force force spacer pin 43 against long through-hole 53 away from rotate slanted kicking block end
Face；One end of back-moving spring 41 is supported on the inner shoulder table 55 of sliding sleeve 5, and the other end is against on pedestal 31；91 sets of trailing wheel connecting tube
In brake lever 8, rotate outside slanted kicking block 7 and sliding sleeve 5, and its end and the port part set of the installation through-hole 311 on rear wheel seat 3
Connect；It is formed with the madial wall of installation through-hole 311 and is engaged axial slide with axial slider 54, so that sliding sleeve 5 is relative
Rear wheel seat 3 can be moved back and forth vertically；Foot-operated 92 sleeve 920 is placed on outside trailing wheel connecting tube 91, and its root passes through opening 911
It is fixedly connected afterwards with installation screw 811.
When not braked, in the presence of the elastic restoring force of back-moving spring 41, make tilting table terrace 52 against oblique side
Wall 71, and in the presence of the elastic restoring force of buffer spring 42, spacer pin 43 is against long through-hole 53 away from rotation slanted kicking block 7
End face on, now, brake pin 6 is located at insertion position with respect to sliding sleeve 5, and sliding sleeve 5 is mounted opposite through hole 311 and is located at
Off-position.
In brake process, rotated by trampling foot-operated 92 driving brake bar 8, and drive the rotation for rotating slanted kicking block 7, by
Slip is acted on abutting between oblique side wall 71 and tilting table terrace 52, so as to promote sliding sleeve 5 axially towards remote
The direction movement of slanted kicking block 7 is rotated, and drives brake pin 6 to stretch out installation through-hole 50 and enter in corresponding spoke hole 212, so that
Whereabouts gear is rotated into trailing wheel 21, that is, reaches brake purpose, now, brake pin 6 is located at insertion position with respect to sliding sleeve 5,
Sliding sleeve 5 is mounted opposite through hole 311 positioned at normal danger.
In tilting table terrace 52 and oblique side wall 71, one constitutes the guide surface of the present embodiment, and another one constitutes this implementation
Example directed section, so as to slide against guide surface and along the guide surface by guide portion and promote sliding sleeve 5 to relatively rotate tiltedly
Jacking block 7 is moved along its axis, and the shape of wherein directed section is not limited to the ramp structure in the present embodiment, can also be one
Slide block structure, such as a protrusion arc end face.
When stopping to riding 92 when trampling, in the presence of the elastic restoring force of back-moving spring 41, sliding sleeve 5 is promoted simultaneously
Drive in the brake retraction installation through-hole 311 of pin 6, can be after so as to release the backstop action rotated to trailing wheel 21, i.e. baby carriage
Continue into, now, brake pin 6 with respect to sliding sleeve 5 be located at insertion position, and sliding sleeve 5 be mounted opposite through hole 311 be located at release
Put position.
When stepping on foot-operated 92, if brake pin 6 can be compressed, so that shape not to spoke hole 212 to buffer spring 42
Into an elastic return, and it is resisted against on the wheel hub side of trailing wheel 21, now, brake pin 6 is located at respect to sliding sleeve 5 exits position
Put, and sliding sleeve 5 is mounted opposite through hole 311 positioned at normal danger；Enter as trailing wheel 21 is rolled in next pin-and-hole, complete
To the braking action of trailing wheel.
Reset of the back-moving spring 41 for brake pin 6 after brake is completed provides reset force, that is, forces the relative peace of sliding sleeve 5
Dress through hole 311 moves to off-position by normal danger and drives brake pin 6 to depart from coupling away from spoke hole 212, in addition, its is extensive
Multiple power also forces tilting table terrace 52 against oblique side wall 71.Buffer spring 42 force brake pin 6 its free end end face not by
In the presence of thrust, make spacer pin 43 against the end face of long through-hole 53, that is, force the brake phase sliding sleeve 5 of pin 6 by exiting position
Insertion position is moved to and with an elastic return, it is thereby advantageously ensured that brake process is smoothly carried out.
Long through-hole 53 constitutes the limit sliding chutes in the present embodiment, certainly by the way that sliding sleeve 5 is designed to by two and half
Structure composition, and limit sliding chutes is run through the side wall of guide chamber 50, and spacer pin 43 can be with integrally formed with brake pin 6
Mode is made.
And by being fixed on backstop of the limited post in spacing post holes 912 to stopper slot 812, with to brake lever 8 relatively after
The mobile carry out of wheel connecting tube 91 vertically is spacing, i.e., spacing post holes 912, stopper slot 812 and limited post constitute this implementation together
The axial limiting mechanism of example.Furthermore, it is possible to by opening 911 and foot-operated 92 roots against constituting the axial limiting mechanism.
