Abstract
The invention relates to a stretching push rod of a baby stroller, which comprises a lower push rod provided with a lower pipe cavity, and an upper push rod; the upper push rod is provided with a locking pin in a slidable mode; the lower pipe body is fixedly provided with a plastic lining piece with a cavity; the upper push rod is inserted in the cavity in a slidable mode; the plastic lining piece is provided with at least two locking holes; the locking pin is provided with a locking operating position and a unlocking operating position, when the locking pin is atthe locking operating position, the locking pin is inserted in a locking hole, when the locking pin is at the unlocking operating position, the locking pin separates from all the locking holes. When the position of the upper push rod is regulated relative to the lower push rod, the upper push rod slides in the cavity of the plastic lining piece, the friction coefficient between the upper push rod and the plastic lining piece is rather small; therefore, the users saves labor in regulation.
Description
Technical field
The present invention relates to a kind of children trolley, especially the expansion pulling handle rod of children trolley.
Background technology
The expansion pulling handle rod of children trolley in the prior art, comprise lower push-rod with following tube chamber, upper push-rod, be provided with stop pin on the described upper push-rod slidably, described upper push-rod directly is inserted in the described tube chamber down slidably, have a plurality of lock holes on the described lower push-rod, during locking, stop pin on the described upper push-rod directly is inserted in the lock hole on the lower push-rod, when needs are regulated the position of the described relatively lower push-rod of described upper push-rod, described upper push-rod slides in the following tube chamber of described lower push-rod, because described upper push-rod and described lower push-rod all are metallic material usually, between the two friction coefficient is bigger in the process of sliding, user's effort during adjusting.
Summary of the invention
The object of the invention provides a kind of expansion pulling handle rod of children trolley, and when regulating the relative lower push-rod of upper push-rod position, the user is more laborsaving.
For achieving the above object, the technical solution used in the present invention is: a kind of expansion pulling handle rod of children trolley, comprise lower push-rod with following tube chamber, upper push-rod, be provided with stop pin on the described upper push-rod slidably, be provided with plastic inner lining spare regularly in the tube chamber under described with cavity, described upper push-rod is inserted in the described cavity slidably, have at least two lock holes on the described plastic inner lining spare, described stop pin has locking and two control positioies of release, when described stop pin is in the locking control position, described stop pin is inserted in the lock hole, when described stop pin was in unlocking position, described stop pin and described whole lock hole all were separated.
Described plastic inner lining spare has madial wall and lateral wall, and described lock hole is for extending to the perforate that described lateral wall and cross-sectional plane reduce gradually from described madial wall.
Have at least two protuberances on the described plastic inner lining spare, described lock hole is correspondingly opened on described protuberance, has at least two holes on the described lower push-rod, and described protuberance correspondingly is inserted in the described hole.
Have last tube chamber on the described upper push-rod, described going up in the tube chamber is provided with traction piece, has lock pin holes on the described upper push-rod, and described stop pin is inserted in the described lock pin holes slidably, and described traction piece is connected with described stop pin.
Because technique scheme utilization, the present invention compared with prior art has following advantage: during owing to the relative lower push-rod of adjusting upper push-rod position, described upper push-rod slides in the cavity of described plastic inner lining spare, friction coefficient between described upper push-rod and the described plastic inner lining spare is less, and the user is more laborsaving during adjusting.

Wherein: 1, lower push-rod; 2, upper push-rod; 3, hole; 4, stop pin; 5, plastic inner lining spare; 6, lock hole; 7, elastic component; 8, traction piece; 11, following tube chamber; 12, go up tube chamber; 13, protuberance; 14, cavity; 15, madial wall; 16, lateral wall; 17, lock pin holes.
The specific embodiment
Shown in each accompanying drawing, a kind of expansion pulling handle rod of children trolley, comprise lower push-rod 1 with following tube chamber 11, upper push-rod 2, be provided with stop pin 4 slidably on the described upper push-rod 2, be provided with plastic inner lining spare 5 regularly in the tube chamber 11 under described with cavity 14, described upper push-rod 2 is inserted in the described cavity 14 slidably, have at least two lock holes 6 on the described plastic inner lining spare 5, described stop pin 4 has locking and two control positioies of release, when described stop pin 4 is in the locking control position, described stop pin 4 is inserted in the lock hole 6, when described stop pin 4 was in unlocking position, described stop pin 4 all was separated with described whole lock holes 6.
Shown in accompanying drawing 2-accompanying drawing 4, described plastic inner lining spare 5 has madial wall 15 and lateral wall 16, and described lock hole 6 is for extending to the perforate that described lateral wall 16 and cross-sectional plane reduce gradually from described madial wall 15.Described lock hole 6 is convenient to stop pin 4 insertions and inserts back stop pin 4 tightr with cooperating of described lock hole 6, and upper push-rod 2 relative lower push-rods 1 are more stable during locking.
Have at least two protuberances 13 on the described plastic inner lining spare 5, described lock hole 6 is correspondingly opened on described protuberance 13, has at least two holes 3 on the described lower push-rod 1, and described protuberance 13 correspondingly is inserted in the described hole 3.
Has last tube chamber 12 on the described upper push-rod 2, described going up in the tube chamber 12 is provided with traction piece 8, have lock pin holes 17 on the described upper push-rod 2, described stop pin 4 is inserted in the described lock pin holes 17 slidably, and described traction piece 8 is connected with described stop pin 4.Be provided with elastic component 7 between described stop pin 4 and the described upper push-rod 2.
During adjusting, such as being in position shown in the accompanying drawing 2 when described upper push-rod 2, the spring force that only need overcome elastic component 7 spurs described traction piece 8, as shown in Figure 3, makes stop pin 4 hole 6 that goes out of lock, this moment is the position of the described upper push-rod 2 relative lower push-rods 1 of scalable just, when being adjusted to the position that needs, decontrol described traction piece 8, as shown in Figure 4, under the effect of described elastic component 7, make described locking lock 4 insert again in another lock hole 6.
