Description

Racing seat belt buckle set

The invention relates to a racing seat belt buckle group, in particular to a racing seat belt buckle group which can avoid mis-opening to improve the safety of use.

According to the safety belt, the safety belt is the most important and basic equipment for protecting the safety of the driver and the passenger. When the vehicle body produces an impact or an emergency vehicle, the vehicle personnel will move forward due to the inertia principle. When the impact force is large, It is easy to hit the steering wheel and windshield in front, causing serious injury. Therefore, the seat belt can effectively generate tension at this time to restrain the human body from being seated on the seat so as not to push forward too much to reduce the damage.

The function of the seat belt buckle is to connect to each belt of the seat belt. According to the use, the seat belt buckle can be divided into two types: general use and racing competitive use, and the common racing competitive seat belt buckle set structure includes a body, a rotating trigger member, and a locking component, wherein the body periphery is provided with five latching slots, and the top surface is disposed at the center and is detached by the internal locking device of the rotating control body. a shaft column, the shaft column is disposed on the top surface of the body and is provided with a square driving portion, and a screw hole is arranged on the square driving portion, and a limiting protrusion is disposed on the top surface of the body body on the side of the shaft column, the rotating beam member A disc is arranged on one side of the disc, a circular groove is arranged in the center of the top surface of the disc, a square sleeve hole is arranged on the groove surface of the circular groove, and a bottom surface of the disc is arranged in an arc shape around the square sleeve hole. Limit slot.

When assembling, the rotating trigger member is placed on the body, so that the square driving portion of the body shaft column is fitted to the square sleeve hole of the rotating trigger member, and the limiting protrusion of the top surface of the body sleeve is sleeved on the bottom surface of the rotating wrench member. In the limiting slot, the locking element is screwed to the screw hole of the body shaft column to rotate the circular groove of the trigger disc to evade the head of the locking component, so that the rotating trigger is coupled with the shaft column of the body. .

Thereby, the buckle of the seat belt buckle can be inserted into the buckle slot of the main body, and the shaft of the main body can be rotated by the rotation of the rotating trigger to unfasten the seat belt, and when the rotary puller is turned The arc-shaped limiting slot cooperates with the limiting protrusion of the top surface of the body to limit the turning angle of the rotating trigger.

However, according to the above, the conventional seat belt buckle structure has a structure in which the rotating trigger directly links the shaft column of the body, so when the vehicle is driven by the seat belt, if the rotating wrench is subjected to an external force, it is slightly inadvertently At the touch, the rotating shaft pulls the shaft column of the main body to rotate, which causes the seat belt buckle to loosen, loses the role of protecting the driver and the passenger, and has poor practicality and safety in use, and needs to be improved.

The spring end of the seat belt 1 is pushed out of the buckle groove 115 of the seat body 1 and, after being disassembled, by the elastic force of the conical spring 34 and the telescopic spring 122 The interlocking piece 35 and the slider 123 are resiliently returned to the original position, so that the blocking portion 1232 provided on the top surface of the slider 123 is again resisted by the movable columns 32 of the locking device 3, and the center is driven. The rotating shaft 36 and the rotating trigger 5 are reversely rotated back to the original position (as shown in Figures 7-10); The shaft hole column 21 at the center of the top surface of the cover body 2 is sleeved by the torsion spring 4; and the limit block 211 at the periphery of the shaft hole column 21 is provided for the two ends of the torsion spring 4 to be abutted The accommodating space 511 of the dome 51 of the rotating trigger 5 is used to cover the top surface of the cover 2 when the rotating plate 5 is attached to the top surface of the cover 2 The shaft hole column 21 and the limiting block 211 and the torsion spring 4; and the limiting block 514 of the receiving space 511 of the dome body 51 also serves to abut the two ends of the torsion spring 4; The through hole 512 of the top surface of the body 51 and the limiting groove 513; the top end of the central rotating shaft 36 of the fastening device 3 is disposed in a fixed state, and the top surface of the limiting block 211 of the cover body 2 is provided. Limit The torsion springs 4 are placed in a limited state; the torsion springs 4 are continuously connected by a linear body 40 to form a torsion portion 41 of the spiral coil, and the torsion portion 41 is provided with a corresponding to the torsion portion 41. The upper and lower ports are provided with a hollowed out area 411 in the communicating state, and the hollowed out area 411 is sleeved on the shaft hole column 21 of the top surface of the cover body 2; and one of the upper and lower ends of the torsion portion 41 is provided The resisting portion 42 is formed to extend outwardly, and the two resisting portions 42 are respectively disposed at two ends of the limiting block 211 on the top surface of the cover 2 and the limiting block 514 in the dome 51 of the rotating trigger 5 The end is in abutment state; therefore, when the user wants to unfasten the fixed end cleat 71 of the safety belt 7, the user rotates the trigger trigger 52 of the rotating trigger 5 to simultaneously drive the dome One of the torsion springs 4 of the limiting block 514 of the body 51 is actuated, and the other abutting portion 42 of the torsion spring 4 continues to resist the limiting block 211 of the top surface of the cover 2, When the resisting portion 42 is actuated, the torsion spring 4 is formed to have a certain resistance, and a certain force must be applied to achieve the unlocking state. The fixed end flaps 71 of the seat belt 7 are pushed out of the latching slots 115 of the base body 1; furthermore, the limiting block 211 of the cover body 2 is placed in the limiting slot 513 of the dome cover 51. Wherein, the rotation angle of the rotary trigger 52 is restricted; thereby, the two resisting portions 42 of the torsion spring 4 are respectively respectively disposed at the two ends of the limiting block 211 of the top surface of the cover 2 and the rotating plate The two ends of the limiting block 514 in the dome 51 of the member 5 are in abutting state, which improves the overall pulling resistance of the rotating trigger 5, which limits the rotating trigger 5 from being inadvertently touched by an external force. It exhibits an arbitrary rotation phenomenon and achieves better anti-missing effect: a car seat belt buckle group that can avoid mis-opening to improve the safety of use.

In summary, a racing seat belt buckle group has not been seen in various books or publicly used, and it is in line with the requirements of the invention patent application, so please ask the Bureau to give a patent, and to pray. It is to be understood that the above is a specific embodiment of the present invention and the technical principles applied thereto, and the functional effects produced by the concept of the present invention are still beyond the spirit of the specification and drawings. In the meantime, it should be combined with Chen Ming within the scope of the present invention.
