Abstract
The utility model relates to a folding lock bar used for children products and a baby stroller. The folding lock bar comprises a first folding rod, a second folding rod and a locking mechanism, wherein one end of the second folding rod is rotationally connected with one end of the first folding rod around a first shaft, and the locking mechanism is arranged between the first folding rod and the second folding rod. When the locking mechanism is to be unlocked and the first folding rod and the second folding rod rotate relatively, a user can press a button to enable a locking part to move out of a lock hole, at this time, a first hook on the button can hook the locking part for unlocking and stopping, so even if the user releases the button, the locking part cannot be reinserted into the lock hole, and use and operation are facilitated. In addition, the first folding rod and the second folding rod can rotate relatively, a guide projection contacts against a step during rotation, and the locking part slides to separate from the first hook, and the button is reset under the action of a reset elastic part.

The specific embodiment
as shown in accompanying drawing 1-accompanying drawing 6, a kind of for articles for children, as the folding locking bar on children trolley, children dinning chair, comprise the second folding rod 2 that an end of the first folding rod 1, an end and the first folding rod 1 is rotationally connected around the first axle 3, be arranged on the lockout mechanism between the first folding rod 1 and the second folding rod 2.The first axle 3 is as shown in Figure 6.
on the end that lockout mechanism comprises the lockhole 21 that is opened on the second folding rod 2, be slidably arranged in the first folding rod 1 and can insert lockhole 21 locking piece 11, be arranged between locking piece 11 and the first folding rod 1 and make locking piece 11 can stably be inserted in the locking piece elastic component 12 in lockhole 21, locking piece 11 only can be along being slidably arranged on the first folding rod 1 perpendicular to the direction of axis line of the first axle 3.
one end of the first folding rod 1 can also be rotated or can be provided with slidably the button 13 sliding for controlling locking piece 11, between button 13 and the first folding rod 1, is provided with return springs 14.In the present embodiment, button 13 is slidably arranged on the first folding rod 1, in 11 two of button 13 and locking pieces, at least one, is provided with guiding surface 17, presses in the process of button 13, and button 13 is inconsistent by guiding surface 17 with locking piece 11.The direction of slip of button 13 is consistent with the direction of axis line of the first axle 3, or the direction of axis line of the direction of slip of button 13 and the first axle 3 and the direction of slip of locking piece 11 all perpendicular also passable.
on button 13, have and hook locking piece 11 and prevent that it from departing from after lockhole 21 and reinsert the first hook portion 15 in lockhole 21, on locking piece 11, there is the second hook portion 16, on locking piece 11, be provided with the guide protrusions 18 of downward protrusion, on the second folding rod 2, offer and dodge space 24 for what accommodate guide protrusions 18 and allow that guide protrusions 18 slides, thereby dodge and in space 24, there is the step 25 that can move with the inconsistent control of guide protrusions 18 locking piece 11, on step 25, there is transition domatic 28, relatively rotate in process guide protrusions 18 and domatic 28 slide on step 25 by transition when locking piece 11 exits lockhole 21 and the first folding rod 1 and the second folding rod 2, the first hook portion 15 is separated with locking piece 11.
also dodge in space 24 tool the first arc surface 26, be positioned at the second arc surface 27 on step 25, transition domatic 28 is between the first arc surface 26 and the second arc surface 27.The first arc surface 26 to the distance of the first described axle 3 is shorter than the distance of the second described arc surface 27 to the first described axle 3.
down touch the button 13, under the effect of guiding surface 17, make locking piece 11 exit lockhole 21, the first hook portions 15 and can catch on the second hook portion 16, thereby reach halted state, now, the first folding rod 1 and the second folding rod 2 can be rotated, guide protrusions 18, under the effect of transition domatic 28, slides on the second arc surface 27 of step, the first hook portion 15 and the second hook portion 16 are separated, and button 13 ejects reset under the effect of return springs 14.And in the time that needs launch the first folding rod and the second folding rod again, when in the first folding rod and the second folding rod rotation process, locking piece 11 directly slips into lockhole 21 in the elastic force of locking piece elastic component 12.
the first axle 3 is eccentric shaft, a relatively side of the line of centers of the first described folding rod 1 length direction and the line of centers of described the second folding rod 2 length directions, and the opposite side of the line of centers of the line of centers of first folding rod 1 length direction of described step 25 described in being positioned at and described the second folding rod 2 length directions.
articles for children are take children trolley as example, comprise be positioned at left side left bridge, be positioned at the right bridge on right side, if left bridge is left push rod, right bridge is right push rod.Or, can also be that left bridge is left rear wheel support, right bridge is off hind wheel support.The other end of the first folding rod 1 and left bridge are rotationally connected, and the other end of the second folding rod 2 and right bridge are rotationally connected.
as mentioned above, we are illustrated according to aim of the present utility model completely, but the utility model is not limited to above-described embodiment and implementation method.The practitioner of correlative technology field can carry out different variations and enforcement in the scope of technological thought license of the present utility model.
