Description

Technical Field

[0001] The utility model relates to the technical field of safety buckles, in particular to a safety buckle device for a seat belt. Background Art

[0002] The safety buckle is a commonly used safety device. It is an important component of the seat belt. It is used to connect the various parts of the seat belt to ensure that the seat belt can be firmly fixed on the user.

[0003] Patent document 201820664455.7 discloses a seat belt buckle and a seat belt device. The seat belt buckle is used to insert into a fixed base to secure the seat belt. The seat belt buckle includes a tongue plate and a tongue cover. The tongue plate includes a snap-fit ​​portion for inserting into the fixed base and a grip portion for gripping. The tongue cover covers the grip portion, and the side of the grip portion has a cutting edge. The tongue cover includes a tongue cover body and a cover plate. The tongue cover body has a groove at the position corresponding to the cutting edge to expose the cutting edge. The cover plate has a shape corresponding to the groove and is detachably mounted in the groove position to cover the cutting edge.

[0004] However, when using a traditional seat belt buckle device, in use environments of varying degrees of complexity, the user may easily accidentally touch the buckle position, releasing the seat belt's limit, thereby failing to protect the user's safety.

[0005] For example, seat belts and safety buckles work together to effectively prevent falls from heights and protect the user's life. The seat belt is inserted into the safety buckle and then fastened to ensure that the seat belt is in use. However, in complex environments, it is easy to accidentally touch the safety buckle and unlock the seat belt, which will fail to protect the user's safety. Utility Model Content

A first return spring 13 is provided on the circumferential outer wall of the second slide rod 12. A mounting groove 6 is provided on the outer wall of one side of the movable buckle 3, and the mounting groove 6 is connected to the first limiting groove 9. A hidden handle 7 is provided on the inner wall of the mounting groove 6, and the hidden handle 7 is connected to the first slide rod 11.

[0026] When the vehicle is in the locked state, the first locking nut 12 is engaged with the first locking nut 13 and the second locking nut 14 is engaged with the first locking nut 13. When the vehicle is in the locked state, the first locking nut 12 is engaged with the first locking nut 13 and the second locking nut 14 is engaged with the first locking nut 13.

[0027] Among them, the first slide bar 11 is pressed against the fixed buckle 1, and the hidden handle 7 is used in conjunction with the first slide bar 11. When the safety buckle is in use, the first slide bar 11 is pressed against the fixed buckle 1. When the safety belt is buckled in the fixed buckle 1 through the movable buckle 3, the first slide bar 11 limits and fixes the safety belt again. By pulling the hidden handle 7 upward and lowering the hidden handle 7, the first slide bar 11 is lifted and lowered to fix and unlock the safety belt.

[0028] Among them, the movable range of the second slide bar 12 is located in the first limiting groove 9 and the second limiting groove 10, the return spring is located between the first slide bar 11 and the first limiting groove 9, the second slide bar 12 is connected to the first slide bar 11 and can move in the first limiting groove 9 and the second limiting groove 10, the first return spring 13 is sleeved on the outer wall of the second slide bar 12, and when the first slide bar 11 moves, the first return spring 13 is squeezed, so that the first return spring 13 is squeezed and reset in the first limiting groove 9, thereby moving the position of the first slide bar 11, and the coordination effect is good.

[0029] Reference Figure 2 In a preferred embodiment, a baffle 8 is provided on one side of the top outer wall of the hidden handle 7 , and both the baffle 8 and the hidden handle 7 are used in conjunction with the mounting groove 6 .

[0030] Specifically, in the original state, there is a gap between the hidden handle 7 and the installation slot 6, and the baffle 8 is used to block the gap to prevent dust from entering the inner wall of the movable buckle 3 at the installation slot 6 position. When the hidden handle 7 is pulled, the baffle 8 moves upward together and moves in the first limit slot 9. When it is lowered, the baffle 8 blocks the installation slot 6 again to prevent dust.

[0031] Reference Figure 1 、 Figure 2 and Figure 3 In a preferred embodiment, the quick-release mechanism includes a moving rod 15 and a moving hole 5 opened on the outer wall of one side of the movable buckle 3. The moving rod 15 is located in the moving hole 5 and contacts the fixed buckle 1. A second return spring 16 is provided on the circumferential outer wall of the moving rod 15. A limiting rod 14 is provided on the outer wall of one side of the movable buckle 3. The limiting rod 14 is inserted into the moving hole 5. The second return spring 16 is located between the fixed buckle 1 and the movable buckle 3. The limiting rod 14 is used in conjunction with the moving rod 15.

[0032] Specifically, after using the movable buckle 3 many times, the second return spring 16 is easily fatigued due to repeated squeezing, and the second return spring 16 needs to be replaced. During the replacement process, the limit of the limit rod 14 is released, and the movable buckle 3 is pulled inward to make the movable rod 15 move in the movable hole 5. After resetting the movable buckle 3, the second return spring 16 falls between the fixed buckle 1 and the movable buckle 3, and then a new second return spring 16 is replaced. Use a tool on one side of the movable buckle 3 to insert the movable rod 15 into the second return spring 16 again to contact the fixed buckle 1, and the limit rod 14 is inserted into the movable hole 5 for limit, so that when the movable buckle 3 moves, the movable rod 15 moves between the movable hole 5 and the limit rod 14.

[0033] Reference Figure 1 and Figure 3In a preferred embodiment, a fixed shaft is provided on the inner wall of the fixed buckle 1, and the connecting frame 2 is connected to the fixed buckle 1 through the fixed shaft. A limiting hole 4 is provided on the outer wall of one side of the connecting frame 2, and a movable shaft is provided on the inner wall of the movable buckle 3. The movable shaft is connected to the inner wall of the limiting hole 4, and the movable buckle 3 is limited in the fixed buckle 1.

[0034] Specifically, the fixed buckle 1, the connecting frame 2 and the movable buckle 3 form a safety buckle as a whole. The connecting frame 2 is connected to the fixed buckle 1 through a fixed shaft. When the movable buckle 3 moves, the movable shaft moves in the limiting hole 4, thereby realizing the inward opening of the movable buckle 3 and pressing against the fixed buckle 1. The linkage effect between the movable buckle 3 and the fixed buckle 1 is good.

[0035] Working principle: When in use, the safety buckle consists of a fixed buckle 1, a connecting frame 2 and a movable buckle 3. The movable buckle 3 is pressed tightly against the fixed buckle 1. When the movable buckle 3 is pulled, the movable shaft moves in the limiting hole 4. While the safety belt is limited in the movable buckle 3, the hidden handle 7 can be pulled upward to drive the first slide bar 11 to compress the reset spring, so that the second slide bar 12 moves upward in the second limiting groove 10, so that the first slide bar 11 moves upward, releasing the limitation of the first slide bar 11 and the fixed buckle 1. After fastening the safety belt in the fixed buckle 1, the hidden handle 7 is lowered, and the second slide bar 12 is released. A sliding rod 11 moves downward to double-limit the safety belt, and the safety belt is fixed and stable. When the second return spring 16 needs to be replaced, the limit of the limit rod 14 is released, and the movable buckle 3 is pulled inward to make the moving rod 15 move in the moving hole 5. After resetting the movable buckle 3, the second return spring 16 falls, and then a new second return spring 16 is replaced. Use a tool on one side of the movable buckle 3 to insert the moving rod 15 into the second return spring 16 and contact it with the fixed buckle 1. The limit rod 14 is inserted into the moving hole 5 for limit, and the second return spring 16 is replaced.
