Description

Technical Field

[0001] The utility model relates to the field of ratchet detection, in particular to a safety belt ratchet pin strength detection device. Background Art

[0002] Automobile seatbelt assemblies are used to protect and secure passengers. The pawl of a seatbelt assembly is a crucial locking mechanism for the seatbelt, ensuring that the belt quickly locks in the event of an accident, protecting the passenger from injury. When the vehicle decelerates suddenly or a collision occurs, the seatbelt pawl instantly locks, restricting the passenger's forward movement. Because the pin on the pawl is a critical connection, testing the strength of the pawl pin is crucial to ensure passenger safety. Currently, there is a lack of specialized testing mechanisms for this pawl pin strength. To improve pawl quality control, a device for testing the strength of the seatbelt pawl pin is needed.

[0026] like Figure 1 and Figure 2 As shown:

[0027] A safety belt pawl pin strength detection device comprises a base 1, a support frame 2, a pressure rod 3, a lifting assembly, a conveying device 6, a punching head 9 and a heavy hammer 10.

[0028] The support frame 2 is fixedly connected to one end of the base 1. The lifting assembly is arranged adjacent to the support frame 2. The inner end of the pressure rod 3 is hinged to the top of the support frame 2. The pressure rod 3 is a long strip structure. Hanging holes 11 are uniformly opened along the axial direction at the outer end of the pressure rod 3. The weight 10 is hung on any of the hanging holes 11. The fixed part of the lifting assembly is fixedly connected to the base 1. The lifting part of the lifting device is used to push the pressure rod 3 upward.

[0029] A guide hole 12 is provided at the top of the support frame 2, and the punch head 9 is slidably mounted in the guide hole 12. A waist-shaped groove is provided in the axial direction on the pressure rod 3, and a notch is provided at the top of the punch head 9 in the axial direction. A push pin 14 is mounted in the notch. The push pin 14 is movably connected to the waist-shaped groove and can slide in the waist-shaped groove. When the pressure rod 3 rotates around the hinge portion of the support frame 2, the pressure rod 3 drives the push pin 14 to slide through the waist-shaped groove, so that the push pin 14 drives the punch head 9 to move in the guide hole 12.

[0030] Specifically, the lifting assembly includes a lifting cylinder 4 and a push rod 5. The bottom of the push rod 5 is fixedly connected to the telescopic end of the lifting cylinder 4. The top of the push rod 5 is provided with a placement groove, and a push pin 14 is provided in the placement groove. The heavy hammer 10 pulls the pressure rod 3 to press on the push pin 14.

[0031] A conveying device 6 is fixedly connected to the support frame 2. The conveying device 6 is a block-shaped structure. A conveying trough 7 is provided on the conveying device 6. The conveying trough 7 is used to convey the ratchet 16. A punching groove 8 is provided on the conveying block along the width direction of the conveying trough 7. The punching groove 8 is connected to the conveying trough 7 and is aligned with the guide hole 12. A collecting groove 15 is provided on the base 1 and is located directly below the punching groove 8.

[0032] Principle of the present utility model: The heavy hammer 10 is hung in the set hanging hole 11 according to the design requirements, and the lifting cylinder 4 drives the push rod 5 to move upward, so that the pressure rod 3 drives the heavy hammer 10 to rise to the specified stroke. A micro switch is provided at the inner end of the conveying trough 7, and the pawl 16 is pushed in from the inlet of the conveying trough 7. When the pawl 16 is pushed in from the conveying trough 7 and contacts the micro switch, the pin of the pawl 16 is just located in the punching groove 8. Then, the lifting cylinder 4 drives the push rod 5 to descend rapidly, and the heavy hammer 10 drives the pressure rod 3 to move downward under the action of gravity. The pressure rod 3 drives the push pin 14 to slide through the waist groove, so that the push pin 14 drives the punch head 9 to move downward in the guide hole 12. The punch head 9 completes a rapid impact on the pawl 16 pin from the guide groove, and the broken pawl 16 pin falls into the recovery groove.
