Description

Technical Field

[0001] This invention relates to the field of child safety seat technology, and more specifically, to an ISOFIX mechanism. Background Technology

[0002] Child car seats are primarily used when children are traveling in a car and effectively protect their safety. They consist of a base that connects to the car seat and a seat attached to the base for the child to sit on. To make the connection between the child car seat and the car seat simpler and more secure, an increasing number of child car seats are choosing to use ISOFIX (International Standards Organization FIX) fastening systems.

[0003] To facilitate the installation of child car seats in car seats, some ISOFIX systems are designed to be rotatably connected to the base. However, the stability of existing ISOFIX telescopic adjustment structures is poor, and the locking mechanism's engagement and disengagement feel is not obvious. Operators are prone to misjudging whether the telescopic adjustment mechanism is in the locked or unlocked state. For example, existing patent CN103496331B discloses a telescopic car child safety seat ISOFIX device, which inserts into a notch on one side of the inner sleeve through a limiting tooth and extends out from a notch on the other side of the inner sleeve. One end of the limiting tooth abuts against one end of the return spring, and the other end of the return spring abuts against a spring seat. The spring seat is located between the inner sleeve and the outer sleeve and moves with the inner sleeve.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0005] In view of the problems in the related technologies, the present invention proposes an ISOFIX mechanism to overcome the above-mentioned technical problems existing in the prior art.

[0006] Therefore, the specific technical solution adopted by the present invention is as follows:

[0007] An ISOFIX mechanism includes an inner shell located within a housing, one side of which extends outside the housing. The housing has a groove matching the inner shell. The inner shell is a hollow structure. An anchor hook is located on one side of the inner shell. A connecting block one is located on one side of the anchor hook. A plastic connecting block is located on the side of the connecting block one away from the anchor hook and within the inner shell. A tension spring connected to the anchor hook is located on one side of the plastic connecting block and above the connecting block one. A connecting block two is located on the side of the plastic connecting block away from the connecting block one. Stop blocks are symmetrically arranged on both sides of the connecting block two. The top of each stop block extends outside the housing. The top of the housing has several evenly distributed locking holes matching the stop blocks. Two sets of stop blocks are transversely arranged on the upper part of the connecting block two. The block has an unlocking pin 1. The stop block has a limiting hole that matches the unlocking pin 1. The limiting hole is pipe-shaped, and the front side of the pipe-shaped limiting hole is a rectangular channel with a horizontal bottom. The handle of the pipe-shaped limiting hole is an inclined channel that communicates with the lower part of the rectangular channel and extends to the upper right. The bottom end of the stop block has a compression spring that connects to the bottom of the inner shell. The connecting block 2 has a sliding block on the side away from the plastic connecting block. The inner shell has an unlocking pin 2 on the side of the sliding block. The inner shell also has an unlocking pin 3 that penetrates the sliding block. One side of the unlocking pin 3 extends to the outside of the inner shell. One side of the inner shell has a matching guide. The inner shell has a locking groove on the side away from the guide and outside the shell. One end of the anchor hook extends into the locking groove.

[0008] Preferably, the top of the anchor hook is provided with a limiting groove that connects to the tension spring, and the anchor hook is connected to the inner shell through a fixed shaft.

[0009] Preferably, the top of the housing and one side of each of the several card holes are provided with a protrusion, and the inner housing and one side of the unlocking pin three are provided with a rivet.

[0010] Preferably, a limiting post is provided inside the inner shell, between the sliding block and the stop block, and above the connecting block 2.

[0011] Preferably, one side of the inner shell has a through hole 1 that matches the unlocking pin 3, and one side of the outer shell has a through hole 2 that is aligned with the through hole 1.

[0012] The beneficial effects of this invention are as follows: through the matching design of the inner shell and the slide groove, the inner shell is slidably connected in the slide groove of the outer shell; the anchor hook, connecting block one, plastic connecting block and connecting block two are respectively movably connected in the inner shell; in the unlocked state, the anchor hook is in a non-engaged state, the locking member is limited by the connecting rod limiting part and the spring, and the front linkage part abuts against the anchor hook to prevent the locking member from disengaging from the slide groove. By using a single locking member, it can be completely locked in the unlocked state. In the locked state, the slide groove can be pushed to slide backward without manual unlocking and sliding. The FIX can achieve single-piece locking in the unlocked state, thus optimizing the FIX structure. Attached Figure Description
