Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle safety, and particularly relates to a seat belt buckle device for preventing accidental unlocking. Background Art

[0002] A seat belt buckle is a device for fixing a seat belt, usually made of metal or plastic. The seat belt buckle locks the seat belt by inserting both ends of the seat belt into the buckle and then pressing the buckle button, ensuring the safety of passengers during vehicle driving. The seat belt buckle is a very important part of the vehicle safety system and can effectively reduce the risk of casualties in traffic accidents.

[0003] Chinese Patent with the publication number of "CN213649520U" discloses an automobile seat belt buckle assembly with high safety performance, which includes a locking tongue. One end of the locking tongue is provided with a connection port, and a connection belt penetrates through the inside of the connection port. One end of the connection belt is movably connected to the connection port, and the connection belt is fixedly connected to the locking tongue. The other end of the connection belt is provided with a first connecting plate, and the connection belt penetrates through the first connecting plate. A rotatable plate is provided on the side wall of the first connecting plate. An activity shaft is provided between the rotatable plate and the first connecting plate, and the rotatable plate and the first connecting plate are movably connected through the activity shaft. When the seat belt is normally used, the first connecting plate and the second connecting plate are fixed by bolts. If the buckle device fails or is damaged, resulting in the locking tongue being unable to be pulled out, affecting the driver. To avoid such a situation, the rotatable plate can be rotated. The rotatable plate is threadedly connected to the second connecting plate. When rotating, the rotatable plate and the second connecting plate will separate, and the seat belt can be unlocked.

[0004] During the use of the above device, although it can play a good role in limiting the installation belt, it still has certain defects and deficiencies in the use process. When a young child rides in a car and uses the vehicle seat belt, because children are relatively naughty and like to press novel devices everywhere, it is very easy to accidentally press the unlocking button to unlock the car seat belt lock. Once the buckle is accidentally unlocked, it is extremely easy to pose a safety hazard to children. Therefore, it needs to be improved. Content of the Utility Model

[0005] Aiming at the problems mentioned in the background art, the purpose of the utility model is to provide a seat belt buckle device for preventing accidental unlocking to solve the problems raised in the background art.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:

[0008] The limiting mechanism includes a square groove and a limiting groove. The square groove is opened on one side of the housing. Both ends inside the square groove are fixedly installed with telescopic springs. The outer ends of the telescopic springs are fixedly installed with a concave frame. One side of the concave frame close to the housing is fixedly installed with a clamping block. The limiting groove is opened on one side of the plug close to the clamping block, and the clamping block is inserted into the inside of the limiting groove. The middle part of the outside of the concave frame is fixedly installed with a pull rod, and the outer end of the pull rod is fixedly installed with a pull ring. By setting the limiting mechanism, during the use of this device, the telescopic spring can be used to push the clamping block into the inside of the limiting groove. Through the mutual limitation of the clamping block and the limiting groove, the plug can be assisted to be fixed inside the housing, and then the plug and the housing can be quickly locked and fixed, which is convenient for the use of this device. And with the setting of the pull ring and the pull rod, the pull ring can be pulled to drive the pull rod to pull the clamping block away from the limiting groove, which is convenient for quickly disassembling and assembling this device.

[0009] As a preferred technical solution, a reserved groove is opened on one side of the front cover close to the square groove, and the position of the reserved groove corresponds to the position of the pull ring. By setting the reserved groove, during use, the position of the pull ring can be reserved through the reserved groove, which is convenient for pulling the pull ring to disassemble the plug.

[0010] As a preferred technical solution, a filling plate is fixedly installed in the middle of one side of the shielding plate close to the front cover, and the filling plate is inserted into the inside of the reserved groove. By setting the filling plate, the reserved groove can be blocked by the filling plate, which can close the pull ring and improve the closing effect.

[0011] As a preferred technical solution, the shielding mechanism includes a groove, which is opened at one end of the housing close to the plug. A rotating shaft is rotatably connected inside the groove, and a shielding plate is fixedly installed on the outside of the rotating shaft. One side of the shielding plate close to the square groove is fixedly installed with a magnetic stone, and the magnetic stone is magnetically connected to the housing. By setting the shielding mechanism, during the use of this device, the outside of the square groove can be assisted to be blocked by the shielding mechanism, which is convenient for blocking the outside of the pull ring of the limiting mechanism and can avoid the situation that children accidentally touch and unlock. The setting of the magnetic stone can stably adsorb the shielding plate and improve its shielding effect and stability.

[0012] As a preferred technical solution, one side of the clamping block is provided with an inclined surface. The inclined surface of the clamping block is arranged at one end close to the plug. The cross-sectional shape of the end of the plug is arranged in an isosceles triangle. The arrangement of the inclined surface can assist in guiding during installation and quickly install and combine this buckle device.

[0013] As a preferred technical solution, a support plate is fixedly installed on the side of the outer shell away from the plug.

By setting the installation plate at the outer end of the support plate, the outer shell can be assisted in installation through the installation plate and bolts during use, facilitating the quick installation of the outer shell.

[0014] As a preferred technical solution, a connecting frame is fixedly installed on the outer side of the plug. A fixing ring is fixedly installed at the outer end of the connecting frame. By setting the connecting frame, during use, the safety belt can be assisted in connection through the fixing ring at the outer end of the connecting frame, which can achieve a better protection effect.

[0015] In summary, the present utility model mainly has the following beneficial effects:

[0016] First, during the wearing process, the plug can be inserted into the slot. When the clamping block contacts the limiting groove, the telescopic spring resets and drives the clamping block to insert into the limiting groove. Through the mutual limitation of the limiting groove and the clamping block, the plug and the outer shell can be assisted in being combined and limited. Since the telescopic spring is used to resist the clamping block for elastic limitation, during the process of unfastening the safety belt, it is necessary to pull the pull ring to drive the pull rod to pull the concave frame for disassembly. Compared with the prior art where the installation belt adopts a push-button unlocking design, it can avoid the problem of accidental unlocking caused by children accidentally pressing, effectively improving the installation stability of this device and preventing children from accidentally unlocking.

[0017] Second, by setting the shielding mechanism, during the use of this device, after the plug is inserted into the interior of the outer shell, the baffle can be shielded and fixed outside the square groove through the adsorption of the magnetic stone plate. After the baffle shields the outside of the square groove, it can assist in shielding the pull ring. At this time, the filling plate fills the interior of the reserved groove, which can shield the pull ring and the pull rod after the safety belt is buckled and worn, preventing children's fingers from reaching into the reserved groove to pull the pull ring, further improving the stability of the buckle device, enhancing the anti-accidental unlocking ability of this device as a whole, and improving safety.
