Detailed description of the invention
see Fig. 1 to Fig. 3, this example provides a kind of for the lockout mechanism by relative with rod member 6 for rod member 1 locking.Lockout mechanism comprises the sliding part 2 be slidably arranged on rod member 1, the locking piece 3 be slidably arranged on sliding part 2, be opened on rod member 1 and the auxiliary section of matching with locking piece 3, unlock piece 5.In the present embodiment, described auxiliary section is lockhole 4 or locked groove, and when lockout mechanism is in the lock state, locking piece 3 is plugged in lockhole 4 or locked groove, and when lockout mechanism unlocks, locking piece 3 departs from lockhole 4 or locked groove.
unlock piece 5 is rotationally connected respectively by the first pivot a, the second pivot b and sliding part 2 and locking piece 3, first pivot a is parallel with the second pivot b, and vertical with the direction that locking piece 3 slides on sliding part 2, wherein the first pivot a than the second pivot b closer to rod member 1.Particularly, an end of locking piece 3 to be rotated with unlock piece 5 by the second pivot b and is connected, and the end relative with a described end of locking piece 3 coordinates with lockhole 4 or locked groove and lock.When unlock piece 5 rotates for axis with the first pivot a, what locking piece 3 can be driven to slide coordinates with lockhole 4 or locked groove or departs from.Particularly, when unlock piece 5 is towards the A shown in Fig. 2 to rotation, locking piece 3 under the drive of unlock piece 5 towards sliding away from the direction (in Fig. 2 B to) of lockhole 4 thus depart from lockhole 4 and realize unlocking, otherwise, when unlock piece 5 is towards when rotating in the opposite direction with A, locking piece 3 realizes locking towards sliding near the direction of lockhole 4 thus be inserted in lockhole 4 under the drive of unlock piece 5.
further, lockout mechanism also comprises the reduction torsion spring (not shown) being arranged between sliding part 2 with unlock piece 5 and both ends and being fixedly connected with unlock piece 5 with sliding part 2 respectively.Locking piece 5 can be transformed into lock-out state from released state under the effect of reduction torsion spring.
in this example, sliding part 2 is specially the sliding sleeve be set on rod member 1.Sliding part 2 has accommodation space 20, locking piece 3 is housed in this accommodation space 20.
the unblock principle of this routine lockout mechanism is: apply external force and pull unlock piece 5, and make it with the first pivot a for axis rotates along A direction, then locking piece 3 departs from lockhole 4 along B to moving under the drive of unlock piece 5 in sliding part 20, so just completes unblock;
the locking principle of this routine lockout mechanism is: unclamp unlock piece 5, then unlock piece 5 rotates in the opposite direction towards with A side under the effect of reduction torsion spring, locking piece 3 is inserted in lockhole 4 along moving in the opposite direction with B under the drive of unlock piece 5 in sliding part 2, so just completes locking.
lockout mechanism above-mentioned in this example can be applied on children trolley.As shown in Figure 4, this example also provides a kind of children trolley comprising above-mentioned lockout mechanism, and its vehicle frame comprises the side stand 7, front component 8, the wheel assembly 9 that are positioned at both sides.The seat bar 74 that the rear wheel support 73 that each side stand 7 comprises bottom is provided with the front-wheel support 70 of front component 8, upper end is provided with handle 71 push rod 72, bottom is provided with wheel assembly 9, rear ends are rotationally connected with front-wheel support 70 and rear wheel support 73 respectively.Front-wheel support 70 and push rod 72 form (under be referred to as front-wheel support) by a bar.The side stand 7 of both sides is equipped with described lockout mechanism.The sliding part 2 of lockout mechanism can be slidably arranged on front-wheel support 70 along the length direction of front-wheel support 70, and the upper end of rear wheel support 73 rotates with sliding part 2 and is connected.Go-cart also comprises the solution lock strap 10 that both ends are connected with the unlock piece 5 of the lock cell of both sides respectively.Pull solution lock strap 10 lockout mechanism can be made to unlock and drive sliding part 2 along front-wheel support 70 upward sliding, meanwhile, the bottom of rear wheel support 73 is towards the folding near the motion of the direction of front-wheel support 70.Folding operation is convenient.
above the utility model is described in detail; its object is to allow the personage being familiar with this art can understand content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to Spirit Essence of the present utility model change or modify, and all should be encompassed in protection domain of the present utility model.
