[0003] However, the existing ISOFIX assembly that allows for quick docking has the following drawbacks: for example, traditional ISOFIX requires precise alignment with the vehicle anchor point and ensures that the child safety seat is already in place, making the operation cumbersome, especially for new parents, and difficult to remove when the child safety seat is not in use. Summary of the Invention
[0004] The purpose of this application is to enable the rapid connection between child car seats and car seats.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: A fixed bracket is included, with a telescopic rod inside the fixed bracket. An adjustment cavity is formed inside the telescopic rod. Multiple sliding grooves are formed on the left inner wall of the adjustment cavity. A bayonet groove is formed at one end of the telescopic rod. Two stop block grooves are formed on the inner wall of the bayonet groove. Multiple first springs are fixedly connected to the inner walls of both stop block grooves. A stop block is fixedly connected to one end of each of the two first springs. Linkage columns are fixedly connected to both sides of the stop block. Two U-shaped plates are provided inside the adjustment cavity. Linkage grooves are formed at the left ends of the two U-shaped plates. The two U-shaped plates are connected by a connecting rod. A pressing block is provided inside the adjustment cavity. Two limit blocks are formed on the outer wall of the pressing block. Two limit grooves are formed on the left inner wall of the adjustment cavity.
[0006] As a preferred embodiment, the stop block groove is connected to the adjustment cavity through a sliding groove, the left outer wall of the two stop blocks is inclined, the linkage column is located inside the linkage groove, the two ends of the U-shaped plate are respectively located inside the two sliding grooves on the same side, the right side of the pressing block is inclined and fits against the connecting rod.
[0007] As another preferred embodiment, a second spring is fixedly connected to the bottom of the limiting block, and the bottom of the second spring is fixedly connected to the bottom of the inner wall of the limiting groove.
[0008] Further preferably, a third spring is fixedly connected to the right side of each of the two U-shaped plates, and there are multiple third springs, one end of each of the multiple third springs being fixedly connected to the inner wall of the adjustment cavity.
[0009] In a further preferred embodiment, the outer wall of the fixed bracket is provided with a positioning groove, the outer wall of the telescopic rod is fixedly connected with a positioning block, the positioning block is located inside the positioning groove, the upper and lower ends of the positioning block are both provided with telescopic grooves, the outer wall of the positioning block is provided with a pull plate groove, the pull plate groove is connected to the telescopic groove, the bottom of the inner wall of the telescopic groove is fixedly connected with a fourth spring, the top of the fourth spring is fixedly connected with a telescopic block, the other end of the telescopic block is fixedly connected with a locking block, and there are two locking blocks, the outer wall of the telescopic block is fixedly connected with a pull plate, and the pull plate is located inside the pull plate groove.
[0010] Further preferably, the inner wall of the positioning groove is provided with toothed grooves on both the upper and lower surfaces, the locking block is located inside the toothed groove, the pull plate groove and the pull plate are both T-shaped, and the right side of the fixing bracket is provided with a bolt groove.
[0011] Compared with the prior art, the beneficial effects of this application are as follows:
[0012] (1) When using, first pull the telescopic rod out from inside the fixed bracket, then insert the telescopic rod into the anchor point of the vehicle seat, aligning the buckle in the anchor point with the slot. Then insert the end of the telescopic rod with the slot into the anchor point. During insertion, the buckle in the anchor point presses against the two stops, causing the two stops to move into the slot. At this time, the first spring connected to the stops is in a compressed state. After the buckle passes the two stops, the first spring rebounds, causing the two stops to return to their original positions and abut against each other, limiting the buckle inside the slot. The telescopic rod needs to be... When the buckle in the anchor point separates, pressing down on the pressing block causes the inclined surface of the pressing block to squeeze the connecting rod. The second spring is compressed, causing the connecting rod and the two U-shaped plates connected to it to move to the right. At the same time, the third spring is compressed. When the U-shaped plates move to the right, the linkage column connected to the outer wall of the stop block moves along the linkage groove opened inside the U-shaped plate. At the same time, under the limiting action of the stop block groove, the two stop blocks retract into the inside of the stop block groove, thereby separating the telescopic rod from the buckle in the anchor point. This device can quickly connect to the car seat anchor point, is easy to disassemble and assemble, and is simple to operate.
[0013] (2) During the process of the telescopic rod extending outward from the fixed bracket, the positioning block moves along the positioning groove. At the same time, the two locking blocks connected to the telescopic block move sequentially in the toothed grooves opened on the inner wall of the positioning groove. During this process, the telescopic block and the locking blocks connected to it move intermittently into the telescopic groove. When the telescopic rod extends outward to a suitable length, the fourth spring connected to the locking block rebounds, causing the telescopic block and the locking block to return to their positions. At this time, the locking block is locked in the corresponding toothed groove, ensuring that the position of the telescopic rod is fixed. When it is necessary to move the telescopic rod, the two pull plates are pulled relative to each other, so that the telescopic block and the locking blocks connected to it can move inside, thereby allowing the positioning block to move along the positioning groove.

[0028] like Figure 1-9The ISOFIX assembly shown includes a fixed bracket 1, a telescopic rod 2 inside the fixed bracket 1, an adjustment cavity 3 inside the telescopic rod 2, a sliding groove 4 on the left inner wall of the adjustment cavity 3, and multiple sliding grooves 4. One end of the telescopic rod 2 has a bayonet groove 5, and the inner wall of the bayonet groove 5 has two stop grooves 6. Each of the two stop grooves 6 has a first spring 7 fixedly connected to its inner wall, and multiple first springs 7. One end of each of the two first springs 7 is fixedly connected to a stop 8, and two linkage columns 9 are fixedly connected to both sides of the stop 8. The adjustment cavity 3 has two U-shaped plates 10 inside, and the left ends of the two U-shaped plates 10 have linkage grooves 11. The two U-shaped plates 10 are connected by a connecting rod 12. The unit is equipped with a pressing block 13, and the outer wall of the pressing block 13 is provided with a limiting block 14, and there are two limiting blocks 14. The left inner wall of the adjustment cavity 3 is provided with a limiting groove 16, and there are two limiting grooves 16. The stop block groove 6 is connected to the adjustment cavity 3 through the sliding groove 4. The left outer wall of the two stop blocks 8 is inclined. The linkage column 9 is located inside the linkage groove 11. The two ends of the U-shaped plate 10 are respectively located inside the two sliding grooves 4 on the same side. The right side of the pressing block 13 is inclined and fits against the connecting rod 12. The bottom of the limiting block 14 is fixedly connected with a second spring 15. The bottom of the second spring 15 is fixedly connected to the bottom of the inner wall of the limiting groove 16. The right side of the two U-shaped plates 10 is fixedly connected with a third spring 17, and there are multiple third springs 17. One end of each of the multiple third springs 17 is fixedly connected to the inner wall of the adjustment cavity 3.
[0029] In use, first pull the telescopic rod 2 out from inside the fixed bracket 1, then insert the telescopic rod 2 into the anchor point of the vehicle seat, aligning the buckle in the anchor point with the slot 5. Next, insert the end of the telescopic rod 2 with the slot 5 into the anchor point. During insertion, the buckle in the anchor point presses against the two stops 8, causing the two stops 8 to move into the stop groove 6. At this time, the first spring 7 connected to the stops 8 is compressed. After the buckle passes the two stops 8, the first spring 7 rebounds, causing the two stops 8 to return to their original positions and abut against each other, thus limiting the buckle inside the slot 5. To separate the telescopic rod 2 from the buckle in the anchor point, press down on the pressing block 13. This causes the inclined surface of the pressing block 13 to press against the connecting rod 12. The second spring 15 is compressed, causing the connecting rod 12 and the two connected U-shaped plates 10 to move to the right. At the same time, the third spring 17 is compressed. When the U-shaped plate 10 moves to the right, the linkage column 9 connected to the outer wall of the stop block 8 moves along the linkage groove 11 opened inside the U-shaped plate 10. Simultaneously, under the limiting action of the stop block groove 6, the two stop blocks 8 retract into the interior of the stop block groove 6, thereby separating the telescopic rod 2 from the buckle in the anchor point.
[0030] The outer wall of the fixed bracket 1 has a positioning groove 18. The outer wall of the telescopic rod 2 is fixedly connected to a positioning block 19, which is located inside the positioning groove 18. The upper and lower ends of the positioning block 19 are both provided with telescopic grooves 20. The outer wall of the positioning block 19 has a pull plate groove 21, which is connected to the telescopic groove 20. The bottom of the inner wall of the telescopic groove 20 is fixedly connected to a fourth spring 22. The top of the fourth spring 22 is fixedly connected to a telescopic block 23. The other end of the telescopic block 23 is fixedly connected to a locking block 24, and there are two locking blocks 24. The outer wall of the telescopic block 23 is fixedly connected to a pull plate 25, which is located inside the pull plate groove 21. During the process of the telescopic rod 2 extending outward from the fixed bracket 1... In the process, the positioning block 19 moves along the positioning groove 18, while the two locking blocks 24 connected to the telescopic block 23 move sequentially in the toothed grooves opened on the inner wall of the positioning groove 18. During this process, the telescopic block 23 and the locking blocks 24 connected to it move intermittently into the telescopic groove 20. When the telescopic rod 2 extends outward to a suitable length, the fourth spring 22 connected to the locking block 24 rebounds, causing the telescopic block 23 and the locking blocks 24 to return to their positions. At this time, the locking blocks 24 are locked in the corresponding toothed grooves, ensuring that the position of the telescopic rod 2 is fixed. When it is necessary to move the telescopic rod 2, the two pull plates 25 are pulled relative to each other, so that the telescopic block 23 and the 24 connected to it are retracted into the interior of the 20, thereby allowing the positioning block 19 to move along the positioning groove 18.
[0031] The inner wall of the positioning groove 18 is provided with toothed grooves on both the upper and lower surfaces. The locking block 24 is located inside the toothed groove. The pull plate groove 21 and the pull plate 25 are both T-shaped. The bolt groove 26 is provided on the right side of the fixing bracket 1.
[0032] Working principle: Before use, first pull the telescopic rod 2 out from the inside of the fixed bracket 1. During this process, the positioning block 19 moves along the positioning groove 18, and at the same time, the two locking blocks 24 connected to the telescopic block 23 move sequentially in the toothed grooves opened on the inner wall of the positioning groove 18. During this process, the telescopic block 23 and the locking blocks 24 connected to it move intermittently into the telescopic groove 20. When the telescopic rod 2 extends outward to a suitable length, the fourth spring 22 connected to the locking block 24 rebounds, causing the telescopic block 23 and the locking blocks 24 to return to their positions. At this time, the locking blocks 24 are locked in the corresponding toothed grooves, ensuring that the position of the telescopic rod 2 is fixed. Then, pull the telescopic rod 2 out from the inside of the fixed bracket 1, and then insert the telescopic rod 2 into the anchor point of the vehicle seat, so that the buckle in the anchor point is aligned with the locking groove 5. Then, insert the end of the telescopic rod 2 with the locking groove 5 into the anchor point. During the insertion process, the locking blocks in the anchor point... The two stop blocks 8 are pressed together, causing them to move into the stop block groove 6. At this time, the first spring 7 connected to the stop block 8 is in a compressed state. After the buckle passes through the two stop blocks 8, the first spring 7 rebounds, causing the two stop blocks 8 to return to their original positions and abut against each other, limiting the buckle inside the snap-fit groove 5. To separate the telescopic rod 2 from the buckle in the anchor point, press down on the pressing block 13, causing the inclined surface of the pressing block 13 to press the connecting rod 12. The second spring 15 is in a compressed state, causing the connecting rod 12 and the two U-shaped plates 10 connected to it to move to the right. At the same time, the third spring 17 is in a compressed state. When the U-shaped plate 10 moves to the right, the linkage column 9 connected to the outer wall of the stop block 8 moves along the linkage groove 11 opened inside the U-shaped plate 10. At the same time, under the limiting action of the stop block groove 6, the two stop blocks 8 retract into the interior of the stop block groove 6, thereby separating the telescopic rod 2 from the buckle in the anchor point.
