[0023] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0024] Example 1:

[0025] This embodiment provides a child carrier with a headrest adjustment mechanism, such as Figures 1-4 As shown, it includes a basket body 1, a headrest 2 and a headrest adjustment mechanism. The headrest 2 and the headrest adjustment mechanism are installed on the basket body 1. The basket body 1 is provided with a shift rail 3, and the shift rail 3 is provided with at least one shift groove 4; the headrest adjustment mechanism includes a locking pin 5 and an adjustment plate 6, the locking pin 5 cooperates with the shift groove 4, the adjustment plate 6 is connected to the headrest 2, and the locking pin 5 is passed through the adjustment plate 6; the adjustment plate 6 and the locking pin 5 are respectively located on both sides of the shift rail 3; the shift rail 3 is provided with a first notch 7, and the first notch 7 is used for the locking pin 5 to pass through.

[0026] The shifting groove 4 and the locking pin 5 cooperate to realize the position adjustment of the headrest 2; the adjusting plate 6 is used to drive the headrest 2 to move synchronously; the design of the first notch 7 allows the locking pin 5 to be assembled with the adjusting plate 6 first, and then the adjusting plate 6 is assembled with the basket body 1. The locking pin 5 only needs to pass through the first notch 7 to be placed on the other side of the shift rail 3. Compared with assembling the adjusting plate 6 with the basket body 1 and then installing the locking pin 5, which will be restricted by the shifting groove 4, the locking pin 5 is assembled outside, the installation space is large, the assembly is more convenient, the assembly efficiency is improved, and the assembly difficulty is reduced.

[0027] In order to prevent the locking pin 5 from falling out, a blocking block 8 is provided on the basket body 1. The blocking block 8 is used to block the locking pin 5 from passing through the first notch 7. During assembly, after the locking pin 5 passes through the first notch 7 and enters the side of the shifting groove 4, the blocking block 8 is installed. The blocking block 8 prevents the locking pin 5 from moving back to the position of the first notch 7, making it impossible for the locking pin 5 to fall out of the first notch 7, thereby ensuring that the locking pin 5 is securely installed.

[0028] To ensure more secure installation of the blocking block 8, the basket body 1 is provided with a protruding reinforcing wall 9, which is provided with a groove 10. Part of the blocking block 8 is located within the groove 10. The basket body 1 is provided with positioning plates 11, which are located on both sides of the blocking block 8. The blocking block 8 is connected and fixed to the basket body 1 by bolts. When the outer wall of the mounting groove 18 is in contact with the blocking block 8, the locking pin 5 is higher than the first notch 7. The design of the groove 10 facilitates the positioning of the blocking block 8 during assembly, reduces the height of the blocking block 8, and improves the blocking effect of the locking pin 5. The design of the positioning plates 11 facilitates the positioning of the blocking block 8 during assembly and cooperates with the groove 10 to ensure that all four sides of the blocking block 8 are blocked.

[0029] In order to ensure reliable sliding of the adjustment plate 6, a slide rail 12 is provided on the basket body 1, and a protruding slide 13 is provided on the adjustment plate 6. The slide 13 is slidably inserted into the slide rail 12. The slide rail 12 cooperates with the slide 13 so that the sliding of the adjustment plate 6 is guided by the slide rail 12.

[0030] In order to ensure reliable sliding of the adjustment plate 6, two slide rails 12 are provided, which have a good guiding effect; the sliding member 13 includes four connecting ends 14, which are connected to the adjustment plate 6. Two connecting ends 14 are provided on each slide rail 12, which makes sliding more reliable; the two connecting ends 14 on the same slide rail 12 are connected by a connecting plate 15, which has better structural stability and greatly improves the comfort of use.

[0031] In order to adjust reliably, Figure 6 As shown, the headrest adjustment mechanism includes a limit block 16, which is provided with a first guide slot 17. The lock pin 5 is inserted into the first guide slot 17. The first guide slot 17 is used to control the vertical movement path of the lock pin 5. Specifically, one end of the first guide slot 17 is a locking end 23. The locking end 23 and the shift slot 4 are in the same vertical plane. The locking end 23 is adapted to the shift slot 4. When the lock pin 5 is simultaneously in the locking end 23 and the shift slot 4, the headrest 2 is locked and cannot move on the basket body 1. The other end of the first guide slot 17 is an unlocking end 24. When the lock pin 5 is in the unlocking end 24, it just disengages the shift slot 4. At this time, the headrest adjustment mechanism is in the unlocked state, and the lock pin 5 can slide on the shift rail 3 to readjust the headrest 2. The first guide slot 17 is a Z-shaped slot.

[0032] To ensure reliable movement of the locking pin 5, the adjustment plate 6 is provided with a mounting groove 18 recessed toward the locking pin 5. A second guide groove 19 is provided within the mounting groove 18, through which the locking pin 5 passes. The second guide groove 19 is used to control the horizontal movement path of the locking pin 5. Specifically, the second guide groove 19 allows the locking pin 5 to slide fixedly on the shift rail 3. The second guide groove 19 is an L-shaped groove that cooperates with the Z-shaped groove to control the horizontal movement path of the locking pin 5. This simple limiting structure significantly reduces production costs.

[0033] In order to ensure the reliable installation of the limit block 16, Figure 5 As shown, the stopper 16 is located in the mounting groove 18; a second notch 20 is provided on the side of the mounting groove 18 facing the headrest 2, and the remaining wall of the mounting groove 18 fits in contact with the stopper 16. The stopper 16 is located in the mounting groove 18, ensuring reliable installation of the stopper 16; the design of the second notch 20 facilitates the insertion and installation of the stopper 16 through the notch, making assembly easy.

[0034] In order to ensure that the limit block 16 is installed reliably, a baffle 21 is provided on the mounting groove 18, and the side of the limit block 16 away from the bottom of the mounting groove 18 is in contact with the baffle 21. The design of the baffle 21 can prevent the limit block 16 from falling out of the notch of the mounting groove 18.

[0035] To facilitate unlocking, the headrest adjustment mechanism includes an unlocking member 22, which is used to disengage the locking pin 5 from the shifting slot 4. The unlocking member 22 is an elastic member. Specifically, the unlocking member 22 is used to slide the locking pin 5 from the locking end 23 to the unlocking end 24. By connecting the elastic member to the locking end 23, when the elastic member is subjected to force, the locking pin 5 slides from the locking end 23 to the unlocking end 24, thereby unlocking the headrest adjustment mechanism. This elastic member has a simple structure and is low in cost.

[0036] Of course, an elastic member can also be provided between the limit block 16 and the groove wall of the mounting groove 18. The elastic member is used to keep the locking pin member 5 at the locking end 23 to achieve locking. When unlocking, it is only necessary to manually push the limit block 16 upwards, and the locking pin member 5 slides from the locking end 23 to the unlocking end 24, thereby disengaging from the gear groove 4 to achieve unlocking.
