The specific embodiment
As Fig. 1-shown in Figure 6, a kind of pushing hands bar of perambulator is regulated lockout mechanism, comprise that internal chamber wall is provided with the first pushing hands rod member 1 of first teeth groove 9, internal chamber wall is provided with the second pushing hands rod member 2 of second teeth groove 8, the described first pushing hands rod member 1, the second pushing hands rod member 2 connects rotationally by rotating pin 7, tooth core 3 is arranged in the inner chamber of the described first pushing hands rod member 1 or in the inner chamber of the second pushing hands rod member 2 axially slidably along the axial line of rotating pin 7, described tooth core 3 has two control positioies, first control position is unlocking position (as shown in Figure 6), under this position, be meshed (this accompanying drawing is that the tooth on the tooth core 3 is meshed with second teeth groove 8) in the tooth on the described tooth core 3 and first teeth groove 9 or second teeth groove 8; Second control position is a locking control position (shown in accompanying drawing 2 and accompanying drawing 4), and under this position, the tooth on the described tooth core 3 is meshed with first teeth groove 9 and second teeth groove 8 respectively; Also be provided with first spring 5 between the described tooth core 3 and the second pushing hands rod member 2; Button 4 is arranged on the first pushing hands rod member 1 slidably, the sidepiece of described tooth core 3 also pushes up the inner end of described button 4, the inner end of described button 4 is provided with hook 10, there is second spring 6 on the top, inside of described button 4, at least be provided with a lock slots 11 on the described second pushing hands rod member 2, described lock slots 11 extends along the direction perpendicular to the axial line of rotating pin 7, its bottom land is the first pushing hands rod member 1, be under first control position at described tooth core 3, described hook 10 is positioned at described lock slots 11 and is hooked in the cell wall of lock slots 11.
Shown in accompanying drawing 3-accompanying drawing 4, the pushing hands bar of perambulator is regulated lockout mechanism and is in the lock state, and the tooth on the described tooth core 3 is meshed with first teeth groove 9 and second teeth groove 8 respectively, and described hook 10 is positioned at the outside of described lock slots 11.
Shown in accompanying drawing 5-accompanying drawing 6, press described button 4, because the inner end of described button 4 heads on the sidepiece of described tooth core 3, described tooth core 3 overcomes the elastic force of first spring 5, slide to second teeth groove 8, break away from first teeth groove 9, realize release, because described hook 10 enters in the described lock slots 11 and hooks the cell wall of lock slots 11, thereby can make tooth core 3 keep first control position.
