Detailed description of the invention
as shown in Figures 1 to 6, a kind of lockout mechanism described in the utility model, comprising connecting element 1, being installed in locking piece 2 on connecting element 1 and for inserting the sliding part 3 coordinating with locking piece 2 in connecting element 1 and lock rotationally.Described connecting element 1 offers chute 4, and the end that described chute 4 extends to connecting element 1 forms opening.Described connecting element 1 is in strip, and described chute 4 is offered along the bearing of trend of connecting element 1.
described locking piece 2 is installed in chute 4, described locking piece 2 is formed with curved end 5 in one end of the opening near described connecting element 1, described locking piece 2 is rotationally connected by pivot and connecting element 1, described connecting element 1 offers the pivotal mounting hole 9 of installing pivot, the axis of described pivot extends and vertical with the bearing of trend of described chute 4 in the horizontal direction.Described locking piece 2 has guide part 8 in the end of the opening near described connecting element 1.Described curved end 5 is for being formed in the evagination curved end of described guide part 8 towards sliding part 3 end.
described sliding part 3 is wedge shape towards an end of curved end 5, and described wedge shape has slope 6.Described sliding part 3 offers guide groove 7, and described guide groove 7 extends to the end that sliding part 3 has slope 6, and described guide groove 7 runs through slope 6 and forms opening.Described guide groove 7 is the rectangle guide groove that edge extends with slope parallel direction at described slope 6 place.
the groove width D1 of described guide groove 7, distance D2 between the side of described guide part 8 and chute 4 sidewall and D3 are all designed to meet international size of squeezing the requirement of folder standard.
when sliding part 3 inserts in the chute 4 of connecting element 1, sliding part 3 slippage in described chute 4, described guide part 8 is positioned at described guide groove 7.The slope 6 of described sliding part 3 and the lower contacts of described locking piece 2, described sliding part 3 props up described locking piece 2 and promotes described locking piece 2 and rotates outside chute 4, when sliding part 3 pushes against mutually with locking piece 2, connecting element 1, described lockout mechanism locking.
above-mentioned lockout mechanism can be used on children trolley.In the present embodiment, described children trolley, comprises vehicle frame, and described vehicle frame is equiped with above-mentioned lockout mechanism.Lockout mechanism described in the utility model can realize the locking of vehicle frame.
the anti-extrusion folder test process that lockout mechanism described in the utility model carries out as shown in Figure 4, Figure 5 and Figure 6.At the initial condition of anti-extrusion folder test, described connecting element 1 is separated with sliding part 3 with the locking piece 2 on connecting element 1.Place between the locking piece 2 and sliding part 3 of connecting element 1 front end one squeeze press from both sides test bar 100.The similar finger shape of described crowded folder test bar 100.When sliding part 3 is close to connecting element 1, and progressively enter in chute 4, described crowded folder test bar 100 contacts with slope 6, due to slope 6 sliding part 3 formed wedge structure make sliding part 3 to hold up gradually during slippage in connecting element 1 squeeze folder test bar 100.Sliding part 3 inserts the bottom being against locking piece 2 after in chute 4, and can give locking piece 2 one thrusts, locking piece 2 pivotally rotates to chute 4 outside direction under the effect of thrust.The curved end 5 of described guide part 8 squeezes folder test bar 100 and contacts, and locking piece 2 can promote with crowded folder test bar 100 along slope 6 outwards movement while rotating to chute 4 outside direction.Press from both sides so squeeze in the process that folder test bar 100 lock at lockout mechanism can not be formed to squeeze.Meanwhile, the groove width D1 of described guide groove 7, distance D2 between the side of described guide part 8 and chute 4 sidewall and D3 all meet the size of the requirement of crowded folder standard.So lockout mechanism described in the utility model meets the requirement of anti-extrusion folder completely, and during use, safety is higher.
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.Different changes and enforcement is carried out in the scope that the practitioner of correlative technology field can permit at technological thought of the present utility model.
