As shown in Figure 12 and Figure 13, stroller wheel locking device of the present invention is used for the wheel 40 for locking or unlocking perambulator.
When user will lock the wheel 40 of perambulator, user can pass through the pedal 30 trampled and be installed in active lock mechanism 10a,
The pedal 30 can drive active lock mechanism 10a spiral cover 12 to rotate, and the spiral cover 12 is driven the reset while rotating
Part 130 is rotated, and back-moving spring 131 is elastically compressed, and return unit 130 accordingly pulls one end of the linkage rope 22 of link gear 20,
The other end of linkage rope 22 then acts on driven locking mechanism 10b return unit 130 and the synchronous axial system of spiral cover 12.Such as Fig. 3, Fig. 6 institute
Show, during rotation, the inclined plane of the pushing and pressing convex portion 120 on the spiral cover 12 can be distinguished the spiral cover 12 of two locking mechanisms 10
Push against the locked component 14 of correspondence；As shown in Figure 10, the Retchet gear type support rod 16 of locked component 14 stretches out wheel seat 11, and stretches into wheel
In 40 lock slots 41, and then wheel 40 is set to be in lock-out state；Now, user can decontrol the pedal 30, make two locking mechanisms
Back-moving spring 131 in 10 drives return unit 130 to reset respectively, makes spiral cover 12 and the counter motion of pedal 30 and resets, puts simultaneously
Pine linkage rope 22.
As shown in Figure 8, Figure 9, to lock the wheel 40 of perambulator and before pushes pedals 30 in user, each wheel seat 11 it
Axial guidance 111 is respectively protruding into the guide groove 161 of the Retchet gear type support rod 16 of correspondence；When user's pushes pedals 30 make spiral cover 12
Pushing and pressing convex portion 120 push against locked component 14 when, the Retchet gear type push rod 15 can promote the Retchet gear type support rod 16 along its axial direction
Motion, makes plural axial guidance 111 exit the guide groove 161 of the Retchet gear type support rod 16, and protrude out the Retchet gear type support rod 16
Go out wheel seat 11, now, the Retchet gear type support rod 16 can make in unidirectional ratchet portion 160 because of the elastic force effect of the pushing and pressing spring 17
Abutting inclined-plane 162 respectively be oriented to ratchet part 150 on guiding surface 151 abut against, produce the Retchet gear type support rod 16
Rotate, as shown in Figure 10, Figure 11, when user decontrols pedal 30, the pushing and pressing spring 17 can Retchet gear type described in resiliency urged
Support rod 16, the pushing and pressing inclined-plane in the plural unidirectional ratchet portion 160 is abutted axial guidance 111 respectively, while make the Retchet gear type
Support rod 16 produces rotation, the plural axial guidance 111 respectively can against unidirectional ratchet portion 160 confined planes 163 and adjacent support
Inclined-plane 162 is connect, makes the Retchet gear type support rod 16 keep protruding out wheel seat 11, and make wheel 40 that lock-out state be presented.
As shown in Figure 12 and Figure 13, when user will unlock the wheel 40 of perambulator, user can trample described step on again
Plate 30, the pedal 30 is set to drive the active lock mechanism 10a spiral cover 12 and return unit 130, and driven locking mechanism 10b
Spiral cover 12 and the synchronous axial system of return unit 130, as shown in Fig. 3, Fig. 6, the pushing and pressing convex portion on the spiral cover 12 of two locking mechanism 10
120 can push against the locked component 14 of correspondence respectively again, as shown in figure 8, making the Retchet gear type support rod 16 of locked component 14 from wheel
Withdrawn in 40 lock slots 41, make wheel 40 that released state be presented, now, user can decontrol the pedal 30, make two locking
Back-moving spring 131 in mechanism 10 drives the return unit 130 to reset respectively, resets spiral cover 12, pedal 30 and linkage rope 22.
As shown in Figure 10, Figure 11, the wheel 40 of perambulator is unlocked and before pushes pedals 30 in user, each wheel seat 11
Axial guidance 111 bear against the confined planes 163 in unidirectional ratchet portion 160 and adjacent abutting inclined-plane 162, when user tramples
Pedal 30 and make spiral cover 12 pushing and pressing convex portion 120 push against locked component 14 when, the Retchet gear type push rod 15 can promote the ratchet
Formula support rod 16, the unidirectional ratchet portion 160 of the Retchet gear type support rod 16 is set to depart from axial guidance 111, now, the Retchet gear type support rod
16 can make the abutting inclined-plane 162 in unidirectional ratchet portion 160 respectively with being oriented to ratchet part 150 because the pushing and pressing of the pushing and pressing spring 17
On guiding surface 151 abut against, the Retchet gear type support rod 16 is produced rotation, as shown in Figure 8, Figure 9, stepped on when user decontrols
During plate 30, the pushing and pressing spring 17 can promote the Retchet gear type support rod 16, make the pushing and pressing inclined-plane in the plural unidirectional ratchet portion 160
Axial guidance 111 is abutted respectively, while the Retchet gear type support rod 16 is produced rotation, and the plural axial guidance 111 can be stretched respectively
In the guide groove 161 for entering the Retchet gear type support rod 16, the Retchet gear type support rod 16 is set to be withdrawn from the lock slots 41 of wheel 40, and make
Released state is presented in wheel 40.
As shown in Fig. 9, Figure 11, when user is in the situation of the unjustified Retchet gear type support rod 16 of lock slots 41 of wheel 40
During the lock out action of lower progress wheel 40, the meeting of locking piece 165 of the Retchet gear type support rod 16 against wheel 40 and withdraws buffering sky
Between in 168, while compress the buffer spring 167, when wheel 40 rotate make lock slots 41 align the Retchet gear type support rod 16 when,
The locking piece 165 can be pushed against by the buffer spring 167 and stretch into lock slots 41 and lock wheel 40.
In addition, as shown in Fig. 8, Figure 10, when the stroller wheel locking device is in the state of wheel 40 is locked, the mark
Show that unit 180 can be pushed against and rotated by the compression spring 181, the locking sign region 182a is shown in the inspection on wheel seat 11
In viewing window 112；When the stroller wheel locking device is in the state of the unblock of wheel 40, the sign unit 180 can be by institute
State Retchet gear type push rod 15 to promote and make the unblock sign region 182b be shown in the inspection windows 112 on wheel seat 11, therefore use
Family can pass through the pattern for inspecting sign region shown in the inspection windows 112, to confirm the state of wheel 40.
In summary, the pushing and pressing convex portion 120 in the spiral cover 12 of two locking mechanisms can by its inclined plane and eccentric setting it
Locked component 14 with clutch function combines, can positively drive locked component 14 produce locking with unblock switching and again
Position, enables the structure type body downsizing of locked component 14, therefore cut compared to being rotated in the prior art using multiple unidirectional ratchets
Alternatively mechanism, the machining accuracy demand of stroller wheel locking device of the present invention is relatively low, can effectively overcome the multiple lists of prior art
To ratchet easily because of the error of the insufficient generation of dimensional accuracy, and its locking and unblock handoff functionality are influenceed, and action has some setbacks, no
The problems such as consistent.
