Specific embodiment
It will again elaborate to the utility model embodiment by above-mentioned attached drawing below.
As shown in Fig. 1 ~ Fig. 6,1. rear wheel seats, 11. mounting holes, 2. brake pedals, 21. mounting discs, 22. foot pedals, 3. are stopped
Vehicle revolving part, 31. inclined-planes, 4. brake pins, 41. heads, 42. bar portions, 43. tapered ends, 44. guiding ribs, 5. brake springs, 6. brakes
Bracing wire.
A kind of stroller rear wheels brake gear as shown in Figure 1 and Figure 2, is related to a kind of brake knot for stroller rear wheels
Structure is mainly made of rear wheel seat 1, brake revolving part 3, brake pedal 2, the brake structures such as pin 4 and brake spring 5.
The rear wheel seat 1 is a horizontal cylindrical mounting base, and 1 inner end of rear wheel seat, i.e. left end is equipped with shown in Fig. 1
Circular groove, so that discoid brake revolving part 3 is installed, the brake revolving part is concentric to be rotatably installed in rear wheel seat 1
Circular groove in.
The brake pedal 2 is that the foot pedal 22 being arranged in mounting disc by circular mounting disc 21 and disjunctor is formed；
The mounting disc 21 is fixed by screws on the outer end face of brake revolving part 3, i.e. shown in Fig. 1 on left side, mounting disc 21
It is relatively movable identical fixing structure between 1 inner end of rear wheel seat, therefore mounting disc 21 just completely encloses brake revolving part 3
In rear wheel seat 1；The trampling when foot pedal 22 is vacantly exposed on rear wheel seat 1 for brake operation, typically downwards
Foot pedal 22 is trampled, with regard to the synchronous rotation of mounting disc 21 and the revolving part 3 that brakes can be driven, is also achieved that rear-wheel brake equipment
Brake operation.
Be equipped in the rear wheel seat 1 axially through mounting hole 11, brake pin 4 and brake spring 5 be installed in the peace
It fills in hole 11.
Wherein, brake pin 4 is made of the head 41 of inner end and the bar portion 42 of outer end, for shown in Fig. 3, Fig. 4, view
Left side is inner end, is outer end on the right side of view, which is more than 42 outer diameter of bar portion, on head 41 and the joint of bar portion 42
Form outer shoulder.
4 inner end of brake pin, namely 41 left end of head are set as tapered end 43, and 41 outer surface of head is equipped with axial prolongs
The guiding rib 44 stretched sees the axial movement for being oriented to brake pin 4 in mounting hole 11；The brake spring 5 is sleeved on bar
In portion 42, and the inner end pushing installation of brake spring 5, on the outer shoulder of brake pin 4, the outer end pushing installation of brake spring 5 is being pacified
Fill hole 11 interior shoulder on, therefore under normality by the elastic pushing tow of brake spring 5 cause brake pin 4 have always move inward, i.e. Fig. 3
The shown trend being moved to the left, at this time tapered end 43 will contact on brake revolving part 3, and 4 outer end of pin of braking, i.e. shown in Fig. 3
42 right end of bar portion is inside contracted in rear wheel seat 1, so as to which rear-wheel brake equipment be made to be in un-brake state.
Meanwhile the revolving part 3 that brakes is equipped with the inclined-plane 31 contacted with tapered end 43, when brake revolving part 3 is by 2 band of brake pedal
Turn is moved, which will form apart from drop, and then driving brake pin 4 is moved out along 31 sliding contact of inclined-plane
It moves, move right shown in Fig. 4,4 outer end of pin, the i.e. right end of bar portion 42 shown in Fig. 4 that brakes at this time stretches out the mounting hole 11 of rear wheel seat 1
It is interior and be meshed with the brake tooth on trailing wheel, so as to which rear-wheel brake equipment be made to be in braking state.
The utility model can be independently mounted on the arbitrary trailing wheel of perambulator and form a foot list brake structure, also can as Fig. 5,
Completely identical in structure two groups are designed with shown in Fig. 6, and two groups of rear-wheel brake equipments are separately mounted to the left rear wheel of perambulator
On seat and off hind wheel seat, and on the brake revolving part 3 of rear-wheel brake equipment that 2 need of brake pedal are fixed on arbitrary rear wheel seat 1
, the brake revolving part 3 of another rear-wheel brake equipment need not set brake pedal 2, need to will only be braked by mounting disc 21
Revolving part 3 is enclosed in rear wheel seat 1, also needs to be equipped with interconnection between the brake revolving part 3 of two groups of rear-wheel brake equipments
Brake bracing wire 6；Therefore, brake pedal 2 is trampled downwards, and the synchronization of two groups of brake revolving parts 3 can be just realized by bracing wire 6 of braking
Rotation is also achieved that the foot dual brake operation of a pair of of stroller rear wheels.
The above is only specific embodiment of the utility model, it should be appreciated by those skilled in the art that any and reality
The equivalent structure design of example is applied, should be included within the scope of protection of this utility model.
