Detailed description of the invention
As shown in Figure 1 and Figure 2, be the first possibility of the present utility model: arm-rest frame before a kind of baby carriage of adjustable angle, comprises handrail body 1 and Connection Block 8, fixing being arranged on baby carriage vehicle frame of Connection Block 8.
Handrail body comprises the handrail tube 2 of protection infant; for the support tube 7 of supporting armrests pipe; support tube 7 is fixedly connected with handrail tube 2; locating dowel pin 5 is slidably fitted with in support tube 7; retracing spring 3 is set between handrail tube 2 and locating dowel pin 5; retracing spring 3 one end acts on handrail tube 2, and one end acts on locating dowel pin 5, is in compressive state all the time.
Support tube 7 end is by rotating shaft and Connection Block 8 normal-running fit, Connection Block 8 is provided with the knock hole matched with locating dowel pin 5, locating dowel pin 5 is provided with shifting part 4, and shifting part 4 is stretched out outside support tube 7 by the bar shaped pilot hole 6 be arranged on support tube 7, so that operation.
Before this baby carriage, arm-rest frame has two states: spacing state and free state.
When before this baby carriage, arm-rest frame is in spacing state, locating dowel pin 5 inserts the knock hole of Connection Block 8, and handrail body 1 is fixing can not rotate.
When before this baby carriage, arm-rest frame is in free state, locating dowel pin 5 departs from the knock hole of Connection Block 8, and retracing spring is in Pre strained state, and now handrail body 1 can freely be rotated.
As shown in Figures 3 to 5, for alternative dispensing means of the present utility model: arm-rest frame before a kind of baby carriage of adjustable angle, comprise handrail body 1 and Connection Block 8, what Connection Block 8 was fixing is arranged on baby carriage vehicle frame, handrail body end is provided with socket joint 13, and socket joint 13 is by rotating shaft and Connection Block 8 normal-running fit.
Engagement piece 12 is set in rotating shaft, and socket joint 13 is provided with the first positioning groove matched with engagement piece 12, corresponding Connection Block 8 is provided with the second positioning groove matched with engagement piece 12, retracing spring 11 is arranged on engagement piece 12 with in Connection Block 8 groove, one end acts on Connection Block 8, and one end acts on engagement piece 12.
Socket joint 13 is provided with button 10, and the first positioning groove is provided with through hole, and button 10 is contacted with engagement piece by this through hole, and can apply application force to it.
During the assembling of this baby carriage, socket joint 13 is fixedly connected with handrail tube 9, the first positioning groove in socket joint 13 is corresponding with the positioning groove position on Connection Block 8 and surround positioning chamber, engagement piece 12 is arranged in this positioning chamber, all the time some is in the second positioning groove engagement piece 12, thus can not circumference rotate, can only slide along rotating shaft, retracing spring 11 is in compressive state all the time.
Before the baby carriage of the program, arm-rest frame has two states: spacing state and free state.
When before this baby carriage, arm-rest frame is in spacing state, when engagement piece 12 connects with the first positioning groove and the second positioning groove respectively, now handrail tube 9 is fixing can not rotate.
When before this baby carriage, arm-rest frame is in free state, engagement piece 12 is return in the second positioning groove, and now handrail body 11 can freely be rotated.
As can be seen from figures 6 to 8, Fig. 6 is schematic diagram when arm-rest frame is in spacing state before baby carriage, now with the first scheme description operation method: when needs transfer free state to from spacing state, upwardly shifting part 4, then locating dowel pin 5 departs from knock hole, now can freely turn to as Fig. 7, Fig. 8 position.When needs transfer spacing state to from free state, decontrol shifting part 4, when handrail tube forwards assigned address to, due to the effect of retracing spring elastic force, automatically locating dowel pin 5 is pushed in knock hole, thus handrail tube is maintained static.
In like manner, when arm-rest frame before baby carriage is first scheme: when needs transfer free state to from spacing state, promote button 10 inwards, button 10 acts on engagement piece 12, make it depart from the first positioning groove, now can freely turn to as Fig. 7, Fig. 8 position.When needs transfer spacing state to from free state, as long as when handrail tube forwards assigned address to, due to the effect of retracing spring elastic force, automatically engagement piece 12 is pushed in the first positioning groove, thus handrail tube is maintained static.
