The cart locking mechanism is located under the locking position, the cart locking hook 7 is located in a state of hooking a locking rod on the cart, the cart locking mechanism is located under the unlocking position, and the cart locking hook 7 is located in a state of being incapable of hooking the locking rod on the cart after rotating. When the base lock mechanism is positioned under the locking position, the cart lock mechanism is also positioned under the locking position; the base lock mechanism is located under the unlocking position, and the cart lock mechanism is also located under the unlocking position. Base latch mechanism, shallow latch mechanism all receive trinity unblock 8 control, and trinity unblock 8 includes along the trinity of extending from top to bottom direction and unlocks portion 81, by the trinity portion of unloading 81 lower parts on the trinity down the part of extending formation forward the unblock portion 82.

And (3) detailed assembly: as shown in fig. 3-6, the three-in-one upper unlocking part 81 is pivotally connected to the seat pocket 2 by a three-in-one unlocking shaft 83 having an axis extending in the left-right direction. The upper portion of the locking part 81 is connected with the cart lock mechanism on trinity, the anterior of the locking part 82 is connected with the front lock hook 3 in a matched manner under trinity, and the lower part of the locking part 81 is connected with the side lock part 4 in a matched manner on trinity.

Shallow latch hook 7 constitutes a relatively fixed whole with unblock adaptor 9 built-up assembly, shallow latch hook 7 rotates along the shallow latch hook axle that left right direction extended around the axial lead and connects on seat pocket 2, shallow latch hook 7 sets up with the upper portion that trinity upward unblock portion 81 can slide and can the pivoted be connected, specifically, pin shaft pole 91 has on unblock adaptor 9, the upper portion that trinity upward unblock portion 81 has along the spout 84 that upper and lower side extended, pin shaft pole 91 inserts and can slide and can the pivoted be connected in spout 84.

As shown in fig. 2 and 3, the front lock hook shaft 31 of the front lock hook 3 extending in the left-right direction around the shaft axis is pivotally connected to the front portion of the seat pocket 2, a front lock hook elastic member for making the front lock hook 3 under the locking position is disposed between the seat pocket 2 and the front lock hook 3, the front portion of the three-in-one lower unlocking portion 82 is provided with a front lock hook guide groove 86, the front lock hook 3 is provided with a front lock hook post 32 deviating from the front lock hook shaft 31, and the front lock hook post 32 is rotatably inserted into the front lock hook guide groove 86.

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.

The present embodiment is only an example of the locking and unlocking process of the front locking hook 3, the cart locking hook 7 and the side locking piece 4 connected to the three-in-one unlocking piece 8. The installation of the front latch hook 3, the stroller latch hook 7, and the side latch 4 is not unique, and the front latch hook 3 may be configured to slide back and forth, and the side latch 4 may be configured to rotate around an axis along a rotation axis in the back and forth direction. The advantages of novel design, convenient and fast unlocking, stable and safe locking can be exerted as long as the displacement can be generated through the control of the three-in-one unlocking piece 8.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
