Abstract
The utility model relates to a brake rod structure of baby cart, which is main to provide an apparatus on the brake rod under the baby cart wheel seat, an elastic extension arranged at one end of the brake rod; by means of the brake rod direct extension or adding a metal flat, the elastic extension is positioned with the wheel shaft or wheel seat through the own elasticity of the elastic extension, so as to avoid the abrasion and invalidation of the elastic extension for long time usage.
Description
Technical field
The utility model is a very bar structure of a kind of perambulator.
Background technology
General perambulator at the position of its wheels all device brake device is arranged, when making it be provided at parked perambulator, avoid perambulator to move thereby cause danger because of the relation of landform; And for making its perambulator avoid during state this handbrake lever to break away from brake, or anti-terminating in when discharging the brake state, this handbrake lever is fallen into automatically and is formed automatic brake state, generally is provided with the detent mechanism of two condition respectively between its handbrake lever and wheel seat.
Please be with reference to shown in the 1st figure and the 1a figure, for commonly using wheel seat 1 and handbrake lever 2 structures, wherein this handbrake lever 2 is socketed on the rear end of wheel seat 1, wherein in this wheel seat 1 and this handbrake lever 2 sockets part, has the protruding grain 11 in a location, and the location in wheel seat 1 of this handbrake lever 2 protruding grain 11 opposite positions are provided with two detents 21, and when forming the brake state or discharging the brake state in handbrake lever 2 rotations by this detent 21, this detent 11 enters the protruding grain 11 in this location respectively and forms positioning states.
The right above-mentioned structure of commonly using, because the protruding grain in this location 11 when entering second groove by first groove, is obsessive entering, after long-time the use, protruding of this location is caused wearing and tearing easily, in order to do the effect inefficacy that makes this location.
Goal of the invention
The utility model main purpose is: very bar structure of a kind of perambulator is provided, to solve the protruding grain in location in the middle of the conventional construction, because of force to move between two detents, causes the wearing and tearing of protruding of this location easily and the disappearance that lost efficacy after using for a long time.
Technical scheme
The technical solution of the utility model is: a kind of perambulator handbrake lever structure, main device be in the perambulator with the wheel seat that runs through for wheel shaft, include one with the treadle of this wheel seat pivot joint;
One is connected in the brake portion of this treadle; And
The one elastic extension portion that is connected with one of this treadle end connects with this wheel shaft by its elastic properties of materials, perhaps connects with this wheel seat by its elastic properties of materials.
Technique effect
The utility model mainly is provided with elastic extension portion in one of this handbrake lever end, with wheel shaft or the mutual butt of wheel seat, uses wearing and tearing to lose efficacy to avoid elastic extension portion because of the permanent time by the elasticity of this elastic extension portion itself.

The specific embodiment
At first see also shown in the 2nd, 3 figure, this creation is a kind of perambulator handbrake lever structure, and its main device is on the wheels 3 of perambulator skeleton, and wherein these wheels 3 can be installed on the end of the pin pipe 4 of this perambulator skeleton, use mobile perambulator skeleton; These wheels 3 wherein; The wheel body 33 and the wheel seat 34 that include a wheel shaft 31, have a brake tooth 32 are formed, and its this wheel seat 34 is the end that is fixed in this pin pipe 4, by the running through and articulate wheel body 33 of this wheel shaft 34, use a year moving perambulator skeleton.
In addition, handbrake lever 5 is to be articulated in one of this wheel seat 34 end, includes a treadle 51, brake portion 52 and an elastic extension portion 53 at least; Wherein this treadle mainly provides the operator to trample, and should brake portion 52 be to connect or by directly extending one of this treadle 51 end both sides, drive brake portion 52 by the rotation of this treadle 51 and form clip or release, use forming the brake state or discharging the brake state with brake tooth 32.
Elastic extension portion 53, main system is connected in one of treadle 51 end, and in the middle of present embodiment, this elastic extension portion 53 can directly be extended or additional metal shell fragment 6 (as the 5th figure shown in) is held in one of treadle 51 by one of this treadle 51 end; And 53 ones of this elastic extensiones include one first location division 531, second location division 532 and an elastic portion 533, in the middle of present embodiment, when brake portion 52 is positioned at release brake state (shown in the 4th figure), this first location division 531 is to connect with wheel shaft 31 to form the location, and when forming the brake state when desiring to make this brake portion 52 to enter brake tooth 32, this elastic extension portion 53 can enter second location division 532 by first location division 531 by elastic portion 533 via the drive of treadle 51, in order to do making it form brake state and location (shown in 4a figure).
Please refer to shown in the 5th figure.The wheel seat 34 of the utility model is directly to extend projection 341, makes itself and this elastic extension portion 53 butts and locatees and form the brake state and discharge the brake state.
