Description
Technical field
The utility model is related to perambulator field, spy is related to a kind of baby cart back rest angle regulator.
Background technology
The backrest of perambulator needs to adjust angle, and making baby that can sit in the car can lie.The reclining apparatus of the prior art is a variety of,
The easy one end having falls off, dangerous；Also drawstring adjusts angle, but existing reclining apparatus structure is complex.
Such as Chinese invention patent《Perambulator and its backrest angle adjusting apparatus》(application number：201510085050.9) open
The arc-shaped distribution of card slot that is arranged in fixed seat simultaneously forms multi-segment formula structure, when the locking piece docking in drive seat is fastened on
When in the card slot of different sections, the angle of inclination i.e. difference relative to frame body is leaned against, to realize perambulator of the present invention
The multisection type of backrest angle is adjusted.But that there is also structures is complex for the device, and operating personnel need to bend over to operate.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of baby cart back rest angle regulator.This practicality
It is novel to move back rest by the way that release handle to be mounted on, and by the adjusting of the draw ring of release handle realization backrest angle, to make
For operating personnel without bending over, adjustment process is convenient and simple in adjustment process, and will not fall off when operation, and safety is good, and outer
Shape beauty class is high.
The technical solution of the utility model is：A kind of baby cart back rest angle regulator, including fixed frame, mobile backrest
Frame, release handle adjust line, tumbler, and mobile back rest is mounted on by two tumblers on fixed frame, release handle installation
On mobile back rest, two tumblers adjust line by two and are connect with release handle, and it includes groups of metal filaments to adjust line, special
Sign is：Tumbler includes fixing shell, rotational shell, fast pulley, rotating wheel, the concave-convex flank of tooth, guide post, spring, is fixed
Wheel is mounted in fixing shell, and multiple guide posts are arranged on rear side of rotating wheel, and guide post is fixed on rotational shell, is set in guide post
Spring is set, rotating wheel is connected to one end of groups of metal filaments, the draw ring connection of the groups of metal filaments other end and release handle；Fast pulley and rotation
The concave-convex flank of tooth of setting on front side of runner, concave tooth and the distribution of double wedge uniform crossover.
According to baby cart back rest angle regulator as described above, it is characterised in that：Adjust line further include surrounding layer, it is interior
Lining, liner layer are set in surrounding layer, and surrounding layer is arranged in length direction natural torsion state, groups of metal filaments in liner layer
It is interior.
The utility model has the beneficial effects that：First, will not fall off when operation, safety is good, and good appearance class
It is high.Second is that easy to operate, release handle setting is by back, and operating personnel are without bending over.Third, simple in structure, adjusting angle is big,
Mobile back rest load-bearing capacity is larger.

Reference sign：Fixed frame 1, release handle 3, adjusts line 4, surrounding layer 41, liner layer 42, gold at mobile back rest 2
Belong to silk group 43, tumbler 5, fixing shell 51, rotational shell 52, fast pulley 53, rotating wheel 54, the concave-convex flank of tooth 55, guide post
56, spring 57.
Specific implementation mode
The technical solution of the utility model is described further below in conjunction with attached drawing.
As shown in Figures 1 to 6, the baby cart back rest angle regulator of the utility model includes fixed frame 1, mobile backrest
Frame 2, release handle 3 adjust line 4, tumbler 5, and mobile back rest 2 is mounted on fixed frame 1 by two tumblers 5, adjusts
Handle 3 is mounted on mobile back rest 2, and two tumblers 5 adjust line 4 by two and connect with release handle 3, pull release handle 3
On draw ring, the rotating wheel 54 of tumbler 5 can be made to move backward, fast pulley 53 and the concave-convex flank of tooth 55 of rotating wheel 54 is made to divide
From rotational shell 52 then can be rotated, to realize the adjustment of mobile back rest 2.
As shown in Figures 2 to 4, the tumbler 5 of the utility model includes fixing shell 51, rotational shell 52, fast pulley
53, rotating wheel 54, the concave-convex flank of tooth 55, guide post 56, spring 57, fast pulley 53 is mounted in fixing shell 51, after rotating wheel 54
Multiple guide posts 56 are arranged in side, and guide post 56 is fixed on rotational shell 52, and spring 57 is arranged in guide post 56, and rotating wheel 54 connects
It is connected on one end of groups of metal filaments 43,43 other end of groups of metal filaments is connect with the draw ring of release handle 3.It is pulled in this way by draw ring
Rotating wheel 54 is set integrally to move backward, after decontroling draw ring, under the promotion of spring 57, rotating wheel 54 moves forward.This practicality is new
The 54 concave-convex flank of tooth 55 of front side setting of fast pulley 53 and rotating wheel of type, as shown in figure 3, concave tooth and the distribution of double wedge uniform crossover, recessed
The width of tooth is equal or slightly larger than the width of double wedge and passes through moving in rotation back rest after such fast pulley 53, rotating wheel 54 detach
2, the rotating wheel 54 in synchronous drive rotational shell 52 rotates, after the completion of angle adjustment, under the thrust of spring 57, and two teeth
Face is again ratcheting.And since the ratcheting area of the utility model is larger, therefore mobile back rest 2 can be made to bear heavier pressure, and
It is big to adjust angle.
As shown in Figure 5 and Figure 6, the adjusting line 4 of the utility model includes surrounding layer 41, liner layer 42, groups of metal filaments 43, interior
Lining 42 is set in surrounding layer 41, and surrounding layer 41 is arranged in length direction natural torsion state, groups of metal filaments 43 in liner layer
In 42, and golden groups of metal filaments 43 includes more one metal wires, and the length direction of wire is axial consistent and more with liner layer 42
Upper bending twist (is similar to the molding steel wire rope of twisting) to one metal wire along its length, as shown in fig. 6, groups of metal filaments
43 can be 10 to 30 one metal wires, such as 18.43 one end of groups of metal filaments is fixedly connected on 54 center location of rotating wheel, metal
Silk 43 other ends of group are connected on the draw ring of release handle 3.
The baby cart back rest angle regulator course of work of the utility model is：Pull the draw ring of release handle 3, fast pulley
53, rotating wheel 54 detaches, and rotates mobile back rest 2 and arrives required angle, then unclamps release handle 3, make fast pulley 53, rotating wheel 54
It is mutually ratcheting, that is, complete the adjusting of backrest angle.
