[0002] The seat belt is the only guarantee for the driver's driving safety and is an active safety device. The seat belt buckle, that is, the seat belt plug, is a device that can be installed in the automobile seat belt socket to tie the seat belt to the occupant.
[0003] When the existing seat belt buckle is in use, it needs to be sleeved on the seat belt. When the metal lock plate of the seat belt buckle is deformed under force, the buckle needs to be replaced. However, since the existing buckle is sleeved on the seat belt, when disassembling and assembling the buckle, it is necessary to first disassemble the entire seat belt. It is necessary to completely remove the seat belt before the buckle can be replaced, and the buckle cannot be quickly replaced, which is inconvenient to use. Therefore, we propose an automobile seat belt buckle to solve the problems raised above. Content of the Utility Model

[0013] Preferably, the inner wall of the transmission groove close to the spring is an inclined surface, and the inclined surface of the transmission groove abuts against the end of the pressure rod through the spring.
[0014] 3. Beneficial effects:
[0015] Adopting the technical solution provided by the present utility model, compared with the prior art, the car seat belt buckle of the present utility model is as follows:
[0016] (1) When the lock plate is bent and the buckle needs to be replaced, the clamping block is driven by the pressure rod to move out of the clamping groove, so that the second buckle frame drives the insertion rod to move out of the slot, and then the first buckle frame and the second buckle frame can be separated, and the buckle can be removed from the seat belt. Then a new buckle is taken out, and the first buckle frame and the second buckle frame are sleeved on the outside of the seat belt through the belt passing groove. When the second buckle frame drives the insertion rod to insert into the slot, when the insertion rod abuts against the clamping block, the clamping block is overcome by the spring force and retracts into the clamping block groove. After the insertion rod is completely inserted into the slot, the spring pushes the clamping block to insert into the clamping groove, fixing the insertion rod in the slot, and then the first buckle frame and the second buckle frame can be fixedly connected to form a complete buckle. Through the split seat belt buckle, after the lock plate of the buckle is damaged, it is not necessary to disassemble the whole seat belt, and the buckle can be quickly and conveniently replaced, effectively improving the practicability of the buckle.
[0017] (2) The buckle is sleeved on the outside of the seat belt through the belt passing groove. After the seat belt is worn, when it is necessary to pull the seat belt to adjust the tightness, the seat belt moves relative to the second buckle frame. The seat belt drives the ball to roll in the ball groove through friction. The rolling friction between the seat belt and the ball replaces the sliding friction between the seat belt and the second buckle frame, effectively reducing the resistance when pulling the seat belt, so as to adjust the tightness after the seat belt is worn.

[0026] Please refer to Figures 1 to 3 , an automobile seat belt buckle, including a first latch frame 1, one end of the first latch frame 1 is connected with a second latch frame 2, and the first latch frame 1 and the second latch frame 2 are spliced to form a belt threading groove 3, wherein,
[0027] One end of the first buckle frame 1 far away from the second buckle frame 2 is fixedly connected with a lock plate 4. On one side of the first buckle frame 1 close to the second buckle frame 2, slots 5 are symmetrically opened. On one side of the second buckle frame 2 corresponding to the slots 5, inserting rods 6 are fixedly connected. On the inner wall of the first buckle frame 1 corresponding to the slots 5, a latch groove 7 is opened.
[0028] On one side of the inserting rod 6 corresponding to the latch groove 7, a clamping groove 8 is opened. A spring 9 is installed in the latch groove 7. A latch 10 is installed on the side of the spring 9 close to the opening side of the latch groove 7. On the outside of the first buckle frame 1 corresponding to the latch groove 7, a pressure rod groove 12 is communicated. On one side of the latch 10 corresponding to the pressure rod groove 12, a transmission groove 11 is opened. A pressure rod 13 penetrates through the pressure rod groove 12.
[0029] When the lock plate 4 is bent and the buckle needs to be replaced, the latch 10 is driven by the pressure rod 13 to move out of the clamping groove 8, so that the second buckle frame 2 drives the inserting rod 6 to move out of the slot 5, and then the first buckle frame 1 and the second buckle frame 2 can be separated, and the buckle can be taken off the safety belt. Then a new buckle is taken out. The first buckle frame 1 and the second buckle frame 2 are sleeved on the outside of the safety belt through the belt passing groove 3. The second buckle frame 2 drives the inserting rod 6 to insert into the slot 5. When the inserting rod 6 abuts against the latch 10, the latch 10 is overcome by the elastic force of the spring 9 and retracts into the latch groove 7. After the inserting rod 6 is completely inserted into the slot 5, the spring 9 pushes the latch 10 to insert into the clamping groove 8 to fix the inserting rod 6 in the slot 5, and then the first buckle frame 1 and the second buckle frame 2 are fixedly connected to form a complete buckle. Through the split-type safety belt buckle, after the lock plate 4 of the buckle is damaged, the whole safety belt does not need to be disassembled, and the buckle can be quickly and conveniently replaced, effectively improving the practicability of the buckle.
[0030] Please refer to Figures 1 to 3 , on one side of the second buckle frame 2 close to the first buckle frame 1, ball grooves 201 are equidistantly opened. Balls 202 are arranged in the ball grooves 201. The balls 202 are spherical, and the outer diameter of the balls 202 coincides with the inner diameter of the ball grooves 201, and the outer diameter of the balls 202 is smaller than the inner diameter of the opening of the ball grooves 201. The buckle is sleeved on the outside of the safety belt through the belt passing groove 3. After the safety belt is worn, when the tightness of the safety belt needs to be adjusted by pulling the safety belt, the safety belt moves relative to the second buckle frame 2. The safety belt drives the balls 202 to roll in the ball grooves 201 through friction. The rolling friction between the safety belt and the balls 202 replaces the sliding friction between the safety belt and the second buckle frame 2, effectively reducing the resistance when pulling the safety belt, so as to adjust the tightness after the safety belt is worn.
[0031] Please refer to Figures 1 to 3, the clamping block 10 is rectangular columnar, and one end of the clamping block 10 close to the opening of the slot 5 is a curved surface. The inner wall of the transmission groove 11 close to the spring 9 is an inclined surface, and the inclined surface of the transmission groove 11 abuts against the end of the pressing rod 13 through the spring 9. After the inserting rod 6 is inserted into the slot 5, it abuts against the curved surface of the clamping block 10, so that the clamping block 10 can be retracted into the clamping block groove 7. When the pressing rod 13 is pressed, the end of the pressing rod 13 abuts against the inclined surface of the transmission groove 11, so that the pressing rod 13 can drive the clamping block 10 to overcome the elastic force of the spring 9 and retract into the clamping block groove 7. Through the special-shaped clamping block 10, the inserting rod 6 and the pressing rod 13 can drive the clamping block 10 to retract into the clamping block groove 7, thereby facilitating the disassembly and assembly of the buckle.
[0032] Working principle: When using this vehicle seat belt buckle, as Figures 1 to 3 shown, first, when the locking plate 4 is bent and the buckle needs to be replaced, the clamping block 10 is driven by the pressing rod 13 to move out of the clamping groove 8, so that the second buckle frame 2 drives the inserting rod 6 to move out of the slot 5, and then the first buckle frame 1 and the second buckle frame 2 can be separated, and the buckle can be removed from the seat belt. Then a new buckle is taken out, and the first buckle frame 1 and the second buckle frame 2 are sleeved on the outside of the seat belt through the belt passing groove 3. When the second buckle frame 2 drives the inserting rod 6 to insert into the slot 5, when the inserting rod 6 abuts against the clamping block 10, the clamping block 10 overcomes the elastic force of the spring 9 and retracts into the clamping block groove 7. After the inserting rod 6 is completely inserted into the slot 5, the spring 9 pushes the clamping block 10 to insert into the clamping groove 8, fixing the inserting rod 6 in the slot 5, and then the first buckle frame 1 and the second buckle frame 2 can be fixedly connected to form a complete buckle. Through the split seat belt buckle, after the locking plate 4 of the buckle is damaged, the whole seat belt does not need to be disassembled, and the buckle can be quickly and conveniently replaced, effectively improving the practicability of the buckle. And the buckle is sleeved on the outside of the seat belt through the belt passing groove 3. After the seat belt is worn, when the seat belt needs to be pulled to adjust the tightness, the seat belt moves relative to the second buckle frame 2, and the seat belt drives the rolling ball 202 to roll in the rolling ball groove 201 through friction. The rolling friction between the seat belt and the rolling ball 202 replaces the sliding friction between the seat belt and the second buckle frame 2, effectively reducing the resistance when pulling the seat belt, so as to adjust the tightness after the seat belt is worn.
