The working process of the present embodiment is described in detail below:

Referring to FIGS. 6 to 9 , when the connecting frame 4 is converted from the storage state to the use state, the connecting frame 4 is turned backward, so that the cross bar 43 is hooked and fixed in cooperation with the locking end 511 , and the second connecting bar 42 It slides out from the rod cavity of the first connecting rod 41 backwards.

When the inclination angle of the base body 1 needs to be adjusted through the support base 2 , referring to FIGS. 8 to 11 , the second locking mechanism 3 is pressed down so that the second locking member 31 slides downward. Through the guiding inclined surface 311 , the downward sliding second locking member 31 further drives the locking pin 34 to slide toward the inner side of the second locking member 31 , the locking pin 34 is separated from the locking groove 21 , and the second locking mechanism 3 is unlocked. At this time, the support base 2 can rotate downward around the first axis a. After the support base 2 rotates downward until the base 100 is at a certain target inclination angle, the second locking mechanism 3 stops pressing down, and the second elastic member 32 drives the The locking pin 34 slides to the outside of the second locking member 31 , and the locking pin 34 is inserted into the locking groove 21 . At this time, the base body 1 is adjusted to a certain target inclination angle through the support base 2 .

When it is necessary to adjust the inclination angle of the base body 1 through the connecting frame 4, referring to FIG. 12 and FIG. 13, the pulling member 53 is pulled backward, so that the first locking member 51 rotates backward around the third axis c to lock the end portion 511 is separated from the cross bar 43 . At this time, the connecting frame 4 can rotate downward around the second axis b. When the connecting frame 4 rotates downward to another target inclination angle, it stops pulling the pulling member 53 backward, and the first locking member 51 is in the first elastic Under the action of the driving force provided by the component 52, it rotates forward around the third axis c, and the cross bar 43 is hooked and fixed in the hook groove of the locking end 511. At this time, the base body 1 is adjusted to the above-mentioned Another target tilt angle.

To sum up, the user can easily adjust the inclination angle of the safety seat. When adjusting the angle, the support base 2 and the connecting frame 4 rotate relative to the base body 1 synchronously, reducing the operation steps that the user needs to perform. , reducing the operating burden of the user; in addition, in the production and application process of the child car safety seat, only one rotating shaft needs to be optimized for structural strengthening, which is beneficial to achieve the strength index of the product and also helps to reduce the base 100 structural weight.
