Technical Field

[0001] The utility model belongs to the technical field of seat belt buckles, and particularly relates to a multifunctional seat belt buckle. Background Art

[0002] The seat belt buckle plays a role in connecting the seat belt. The seat belt is the only guarantee for the driver's driving safety and is an active safety device. It can save lives at critical moments. Even when the vehicle is traveling at a relatively low speed, if a collision or emergency braking occurs, although the inertial force generated is relatively small, it is still sufficient to make the driver and passengers unable to control their bodies and collide with hard parts such as the steering wheel and windshield, causing harm to the body. To protect the driver's safety, seat belts are installed on vehicles.

[0003] There is a seat belt buckle on the seat belt assembly. In the event of an accident, the door may get stuck and cannot be opened. At this time, a window breaker is needed. The existing window breaker is a separate and independent object. When it is needed, it needs to be searched everywhere, which is not conducive to escaping in the first time.

[0004] Based on this, a detachable multifunctional seat belt buckle is designed. Content of the Utility Model

Thus, when pressing down the seat belt buckle, the connecting rod moves upward in the gourd-shaped hole, and the connecting rod can be removed after moving to the large hole of the gourd-shaped hole. The tungsten alloy breaking head fixed at the upper end of the seat belt buckle facilitates the user to break the window glass through the tungsten alloy breaking head at the upper end of the seat belt buckle when holding outside the gourd-shaped hole, which increases the window-breaking function of the seat belt buckle. The plastic sleeve installed outside the tungsten alloy breaking head facilitates the plastic sleeve to protect the tungsten alloy breaking head and prevent the head of the tungsten alloy breaking head from hurting the passengers.

[0013] 2. Through the connecting rod composed of a rod member, a card slot, a nut and a screw rod, the card slot provided at one end of the rod member is used to be stuck in the small hole at the lower part of the gourd-shaped hole, and at the same time, the telescopic member is used to limit the rod member downward, which facilitates the fixation of the connecting plate and the connecting rod. The screw rod fixed at the other end of the rod member is externally screwed with a nut, which facilitates the fixation of the connecting rod and the vehicle seat.

[0014] 3. Through the telescopic member composed of a first sleeve, a second sleeve and a spring, the lower end of the first sleeve fixed at the upper part of the connecting plate is sleeved with the second sleeve, and at the same time, the spring is used to be installed between the first sleeve and the second sleeve, which facilitates the second sleeve to move outside the first sleeve after being extruded, and at the same time, the spring is compressed under the action of the second sleeve, which facilitates the second sleeve to reset when the second sleeve is not subject to external force.
