Description

Technical Field

[0001] This utility model relates to the field of child seats, specifically a child safety seat buckle structure. Background Technology

[0002] Child car seats are car safety devices designed specifically for children of different weights and ages, aiming to improve their safety in vehicles; the correct use of child safety seats can significantly reduce the rate of child injuries and fatalities in traffic accidents; many countries have passed laws mandating the use of child safety seats; child car seats are mainly divided into three types: infant safety seats, conversion seats, and booster seats, each suitable for different age groups and weights.

[0003] Existing child seats are connected to the vehicle body via a connecting structure. After connection, they need to be disassembled by pressing. However, the disassembly and pressing structure is relatively complex and easily damaged. In addition, the space reserved at the pressing position is small, making it difficult to operate manually. This makes it inconvenient to disassemble the child seat. Therefore, there is an urgent need for a device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a child safety seat buckle structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a child safety seat buckle structure, including a seat, a fixing block fixedly disposed on the outer side of the seat, the fixing block being a hollow block, a movable rod slidably disposed inside the fixing block, a groove formed on one side of the fixing block, a slider slidably disposed inside the groove, the movable rod being U-shaped on the side away from the fixing block, a groove formed on one side of the movable rod, a limit block hingedly installed inside the groove, a movable shaft movably embedded inside the movable rod, a stop block fixedly disposed on one side of the movable shaft, and a stop block fixedly disposed on one side of the movable shaft. The device features a rotating mechanism that allows for easy rotation of the movable shaft. During use, the stop block is positioned on one side of the limiting block, restricting the rotation direction of the limiting block so that it can only rotate towards the fixed block. The slider then slides along the groove, causing the movable rod to move to the outside of the fixed block. The movable rod is then inserted into the gap between the seats until the fixed ring welded to the vehicle body presses the limiting block into the interior of the movable rod. Afterward, the limiting block resets under gravity and covers the fixed ring on one side, thus completing the installation. The installation is simple and convenient. During operation, the limiting block prevents the fixed ring from detaching from the movable rod, thereby ensuring that the child seat remains in a fixed position.

[0006] Preferably, the rotating mechanism includes an operating block, a wire rope, a winding roller, a torsion spring, and a cavity. The cavity is located inside the movable rod. The winding roller is fixed to one side of the movable shaft and movably installed inside the cavity. The torsion spring is fixed between the winding roller and the inner wall of the cavity. The wire rope is first fixed to the outside of the winding roller, and then any excess is wound around the outside of the winding roller. The operating block is wound and fixed to one side of the wire rope. In use, the operating block pulls the wire rope, causing the winding roller to rotate and the torsion spring to tighten. The winding roller drives the movable shaft to rotate, causing the stop block to rotate. When the stop block rotates to a position away from the limiting block, the seat can be moved, causing the fixing ring to squeeze the limiting block and rotate, thus facilitating the removal of the fixing ring from the movable rod and completing the disassembly of the seat. The operation is simple and convenient, and no pressing operation is required. The operating block can be pulled in any direction, and it is not affected by limited space.

[0007] Preferably, one side of the slider is fixed to the outside of the movable rod, and the other side of the slider extends to the outside of the groove.

[0008] Preferably, the groove is in communication with the interior of the fixed block.

[0009] Preferably, the stop is located on one side of the limiting block.

[0010] Preferably, one side of the wire rope extends movably to the outside of the slider.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. When this utility model is in use, the stop block is located on one side of the limiting block, which restricts the rotation direction of the limiting block, so that the limiting block can only rotate towards the fixed block. Then, the slider slides along the slide groove, so that the movable rod moves to the outside of the fixed block. Then, the movable rod is inserted into the gap between the seats until the fixed ring welded on the vehicle body squeezes the limiting block and extends into the inside of the movable rod. After that, the limiting block resets under the action of gravity and covers the fixed ring on one side. This completes the installation work. When working, the limiting block prevents the fixed ring from detaching from the movable rod, thereby ensuring that the child seat is in a fixed state.

[0013] 2. In use, this utility model involves pulling the steel wire rope with the operating block, causing the winding roller to rotate and the torsion spring to tighten. The winding roller drives the movable shaft to rotate, causing the stop block to rotate. When the stop block rotates to a position away from the limit block, the seat can be moved, causing the fixing ring to squeeze the limit block to rotate. This facilitates the fixing ring to disengage from the movable rod, completing the disassembly of the seat. The operation is simple and convenient, and no pressing operation is required. The operating block can be pulled in any direction, and it is not affected by small spaces. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a child safety seat buckle structure, including a seat 1. A fixing block 2 is welded and fixed to the outside of the seat 1. The fixing block 2 is a hollow block. A movable rod 4 slides inside the fixing block 2. A groove 3 is opened on one side of the fixing block 2, which communicates with the inside of the fixing block 2. A slider 10 slides inside the groove 3. One side of the slider 10 is welded and fixed to the outside of the movable rod 4, and the other side of the slider 10 extends to the outside of the groove 3. The side of the movable rod 4 away from the fixing block 2 is U-shaped. A groove 5 is opened on one side of the movable rod 4. A limit block 6 is hinged and installed inside the groove 5. A movable shaft 8 is movably embedded inside the movable rod 4. A stop block 7 is welded and fixed to one side of the movable shaft 8. The stop block 7 is located at the limit position. On one side of block 6, there is a rotating mechanism on the side of movable shaft 8 to facilitate the rotation of movable shaft 8. When in use, the stop block 7 is located on the side of limit block 6, restricting the rotation direction of limit block 6, so that limit block 6 can only rotate towards the side of fixed block 2. Then, slide slider 10 along slide groove 3 to move movable rod 4 to the outside of fixed block 2. Then insert movable rod 4 into the gap between the car seat until the fixed ring welded on the car body squeezes limit block 6 and extends into the interior of movable rod 4. After that, limit block 6 resets under the action of gravity and covers the side of fixed ring. This completes the installation work. The installation is simple and convenient. When working, limit block 6 prevents fixed ring from detaching from movable rod 4, thus ensuring that the child seat is in a fixed state.

[0021] The rotating mechanism includes an operating block 14, a wire rope 13, a winding roller 11, a torsion spring 12, and a cavity 9. The cavity 9 is located inside the movable rod 4. The winding roller 11 is welded and fixed to one side of the movable shaft 8 and is movably installed inside the cavity 9. The torsion spring 12 is fixedly installed between the winding roller 11 and the inner wall of the cavity 9. The wire rope 13 is first fixed to the outside of the winding roller 11, and then the excess is wound around the outside of the winding roller 11. One side of the wire rope 13 extends movably to the outside of the slider 10. The operating block 14 is wound and fixed to the wire rope 13. On one side, during use, the operating block 14 pulls the wire rope 13, causing the winding roller 11 to rotate and the torsion spring 12 to tighten. The winding roller 11 drives the movable shaft 8 to rotate, causing the stop block 7 to rotate 180 degrees. When the stop block 7 rotates to a position away from the limit block 6, the seat can be moved, which will cause the fixing ring to squeeze the limit block 6 to rotate, thus facilitating the fixing ring to disengage from the movable rod 4 and completing the disassembly of the seat. The operation is simple and convenient, and there is no need to press. The operating block 14 can be pulled in any direction without being affected by small space.

[0022] Working principle: During use, the stop block 7 is located on one side of the limiting block 6, restricting the rotation direction of the limiting block 6 so that it can only rotate towards the fixed block 2. Then, the slider 10 slides along the slide groove 3, causing the movable rod 4 to move to the outside of the fixed block 2. The movable rod 4 is then inserted into the gap between the seats until the fixed ring welded on the vehicle body presses the limiting block 6 into the interior of the movable rod 4. Afterward, the limiting block 6 returns to its original position under the action of gravity, blocking the fixed ring on one side. This completes the installation. During operation, the limiting block 6 prevents the fixed ring from detaching from the movable rod 4. To ensure the child seat is in a fixed position, the operating block 14 is used to pull the wire rope 13, causing the winding roller 11 to rotate and the torsion spring 12 to tighten. The winding roller 11 drives the movable shaft 8 to rotate, causing the stop block 7 to rotate 180 degrees. When the stop block 7 rotates to a position away from the limit block 6, the seat can be moved, which will cause the fixing ring to squeeze the limit block 6 to rotate, thus facilitating the fixing ring to disengage from the movable rod 4 and completing the disassembly of the seat. The operation is simple and convenient, and there is no need to press. The operating block 14 can be pulled in any direction without being affected by small spaces.
