Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
Part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As depicted in figs. 1 and 2, the present embodiment provides a kind of connection component for barrow armrest.In general trolley
All there is frame body and handle.The first sleeve 1 that the connection component includes being fixedly attached on handle, fixed it is connected to
Second sleeve 2 in frame body, the first push rod 3 and the second push rod 4 being arranged on inside second sleeve 2.
Second sleeve 2 is arranged inside the first sleeve 1, and the first sleeve 1 can rotate relative to second sleeve 2.First pushes away
Bar 3 is arranged in second sleeve 2, and it has the first spiral camber, and the first push rod 3 is connected by the sleeve 1 of pin 5 and first, with
So as to the first sleeve 1 is followed to rotate.Second push rod 4 is arranged in second sleeve 2, and is had and the first spiral camber phase
Second spiral camber of matching.
By above-mentioned setting, when operator applies pressure to handle, the first sleeve 1 can be caused relative to second sleeve 2
Rotate, the first push rod 3 rotates under the drive of the first sleeve 1, and the first spiral camber of the first push rod 3 extrudes the second push rod 4
Second spiral camber is to enable the second push rod 4 to be moved along a straight line its axial direction in the interior edge of second sleeve 2.
Further, the second push rod 4 have radially outward from enlarged portion 41, the enlarged portion 41 bent to form the first ditch
Groove 42.One end of second sleeve 2 has the serrated end 21 of radial contraction, and the serrated end 21 forms second groove 22, flexible member 6
It is sheathed on the second push rod 4, and its one end is in first groove 42, the other end is in second groove 22.In fact, second
Push rod 2 can be resetted by above-mentioned flexible member 6, i.e. the second push rod 2 can rely on the second spiral camber extruding first to push away
First spiral camber of bar 1, the first push rod 1 is promoted to drive the first sleeve 1 to turn to initial position.Flexible member 6 can use
Spring.
Those skilled in the art are it should be understood that set first groove 42 and second groove 22 to be to aid in elastic member
Part 6 preferably positions, in the absence of first groove 42 and the diameter of second groove 22 and flexible member 6 and second sleeve 2
When footpath matches, flexible member 6 can be abutted directly against in the enlarged portion 41 of the push rod 4 of serrated end 21 and second of second sleeve 2, this
When flexible member 6 dislocation will not be also produced because being squeezed.
As shown in figure 3, further, the stopper slot 23 of insertion, the stopper slot can be symmetrically offered in second sleeve 2
23 along the circumferentially distributed of second sleeve 2, but is entirely extended circumferentially over upon not along it.One end of pin 5 in stopper slot 23
The inwall of the first sleeve 1 is fixedly connected with, the other end is fixedly connected with the first push rod 3.Therefore, the first sleeve 1 is relative to second sleeve 2
Rotational angle limited by pin 5 and stopper slot 23, i.e. the first sleeve 1 only can be in predetermined angle relative to second sleeve
2 rotate.Those skilled in the art it should be understood that the quantity of stopper slot 23 and pin 5 is suitable, they can be a pair or
Person is multipair.
In other embodiment, gib block 24 is provided with the inwall of second sleeve 2, the gib block axially divides along it
Cloth.The guide groove being axially distributed along it is provided with the external diameter of second push rod 4 (due to viewing angle problem, not shown in Fig. 2).
Therefore, gib block 24 and guide groove are able to ensure that the second push rod 4 can be along the axial linear movement of second sleeve 2.
In a kind of embodiment of deformation, the first push rod 3 can be arranged directly on the inside of the first sleeve 1, Er Feishe
Put in second sleeve 2, if can keep the first push rod 3 the first spiral camber and the second push rod 4 spiral camber it is reliable
Ground is bonded to each other.
Fig. 4 shows the application example of the connection component provided by the present invention for barrow armrest.The meeting when people's stroller
Apply certain power F to handle, from being L with a distance from the axle center of the first sleeve 1 at holding1, the radius of the first sleeve 1 is R5.Due to people
Arm and handle between can have certain angle α, therefore handle can be by the component F of horizontal direction1With point of vertical direction
Power F2.There is certain frictional force f between first sleeve 1 and second sleeve 2.Cause the first sleeve when power F is delivered to the first sleeve 1
1 when being rotated down, and the first push rod 3 follows the first sleeve 1 to rotate, while the spiral camber of the first push rod 3 is with the spiral shell of the second push rod 4
Revolve curved surface to be in close contact, axial thrust F is produced to the second push rod 43With the thrust F of radial direction4, while the compression spring of the second push rod 4
1, a diameter of R of acting surface of the second push rod 43.When rotatable handle is to certain angle β, due to the first sleeve 1 and the first push rod 3
Between limited bit architecture, handle can not be rotated further.
By above-mentioned configuration, when power F is delivered to the first sleeve 1, as turning moment (F2×L1)≤(f×R5+F4×R3) when,
Relative displacement does not occur for the first sleeve 1 and second sleeve 2, and handle keeps original position motionless；As turning moment (F2×L1) ＞ (f ×
R5+F4×R3) when, the first sleeve 1 is rotated down.Wherein (f × R5) ＜ (F4×R3)。
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
The present invention is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：It still may be used
To be modified to the technical scheme described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic；
And these modification or replace, do not make appropriate technical solution essence depart from various embodiments of the present invention technical scheme spirit and
Scope.
