As shown in fig. 3 and 4, the side locking member 4 is slidably disposed on the seat pocket 2 in the left-right direction, a locking member elastic member 12 is disposed between the side locking member 4 and the seat pocket 2, and the locking member elastic member 12 is a spring, so that the side locking member 4 has an outward pop-up tendency to be stably located at the locking position. The lower part of trinity unlocking part 81 has can with the inconsistent complex boss 85 of side latch fitting 4, has the promotion on the boss 85 the domatic 851 of direction of side latch fitting 4.
Unlocking the operating system includes:
and a handle member 10, the handle member 10 being slidably provided at the rear of the seat pocket 2 in an up-down inclined direction.
The draw bar 11, the upper part of draw bar 11 is controlled by the handle piece 10, and can be along the back of seat pocket 2 of the slope direction setting that inclines up and down.
The lower part of the traction rod 11 is connected with the lower part of the three-in-one upper unlocking part 81, the lower part of the three-in-one upper unlocking part 81 is provided with a sliding groove 84 extending along the vertical direction, the lower part of the traction rod 11 is provided with a pin rod 111, and the pin rod 111 is inserted in the sliding groove 84.
In this embodiment, the drawbar 11 has two, trinity unlocking piece 8 also has two connecting axles, is located the left and right sides portion of seat pocket 2 respectively, and its upper portion corresponds respectively to be connected in the corresponding lateral part of the left and right sides of handle spare 3, and its lower part corresponds respectively to connect corresponding trinity unlocking piece 8, and of course, the trinity unlocking piece 8 of every side controls preceding latch hook 3, side latch member 4, the shallow latch hook 7 of corresponding side respectively.
When the unlocking operation is performed, as shown in fig. 3, when the handle member 10 is pulled upward to drive the drawbar 11 to pull upward, the drawbar 11 drives the three-in-one upward unlocking part 81 to rotate counterclockwise right around the three-in-one unlocking shaft 83 to drive the upper part of the three-in-one upward unlocking part 81 to move leftward, and the unlocking adaptor 9 receives a leftward moving force from the upper part of the three-in-one upward unlocking part 81 to push and rotate the cart latch hook 7 to unlock. The side locking member 4 is pushed by the boss 85 to be retracted into the seat pocket 2 in the unlocking position. The front lock hook 3 is dragged backwards by the three-in-one lower unlocking part 82, and the front lock hook column 32 slides to the foremost end in the front lock hook guide groove 86 and then is dragged continuously, so that the front lock hook 3 is driven to rotate clockwise to be arranged at an unlocking position, and unlocking is completed.
When the handle member 10 is released, the side locker 4 is returned to be outwardly sprung to be positioned at the locking position by the locker elastic member 12. Under the action of the elastic element of the front lock hook, the front lock hook 3 resets and rotates anticlockwise to be arranged at a locking position. Thereby resetting the three-in-one unlocking member 8.
During the use, base latch mechanism, shallow latch mechanism all are in latched position on seat pocket 2 usually, and direct alright put seat pocket 2 on base 1, thereby locking in locking hook 3 hook groove before locking hook 3 is got into to locking lever 5 overcomes the elastic force of preceding locking hook elastic component and promotes, thereby side locking piece 4 directly overcomes the elastic force of locking piece elastic component 12 and gets into locking groove 6 and lock. This is also true when the seat bag 2 is mounted on the frame of the stroller, which will not be described in detail. When unlocking is needed, the handle piece 10 is pulled.
