Abstract

The utility model provides a lock catch for a safety belt, comprising a lock bracket, a cross beam and an adjusting part, wherein the adjusting part and the cross beam are parallelly fixed on the lock bracket, and the clamping surface of the adjusting part and the cross beam are tangent along the axial direction; the adjusting part is fixed on the lock bracket through a fixing shaft, and a spring twists around the fixing shaft, and the two ends of the spring is clamped in the inner grooves of the adjusting part; and the distance between the counter-clockwise point of the clamping surface and the fixing shaft gradually increases. As the distance between the counter-clockwise point of the clamping surface and the fixing shaft gradually increases, the safety and durability are improved.

Description

A kind of safety belt snap close

Technical field

The utility model relates to a kind of safety belt snap close.

Background technology

The safety belt snap close, the degree of tightness that can regulate safety belt makes that use is more comfortable.General safety belt comprises lock frame, crossbeam and adjusting parts with snap close, regulate that parts and crossbeam are fixed on the lock frame and tangent,, regulate parts and be fixed on the lock frame by fixed axis with the fastening safety band, be wound with spring on the fixed axis, the two ends of spring stick into the inside groove of described adjusting parts.When the adjusting parts counterclockwise moved, the distance between chucking face and the crossbeam increased, and to adjust the degree of tightness of safety belt, made that use is comfortable.But, longer because the chucking face equates with distance between the fixed axis along counterclockwise reverse point when service time, tighten surface wear after, the crystallized ability of safety belt is weakened.

Summary of the invention

The purpose of this utility model provides the stronger safety belt snap close of a kind of crystallized ability.

The utility model provides a kind of safety belt snap close, comprise lock frame, crossbeam and adjusting parts, described adjusting parts and crossbeam are fixed on the lock frame abreast, the chucking face and the crossbeam of described adjusting parts are in axial direction tangent, these adjusting parts are fixed on the lock frame by fixed axis, are wound with spring on this fixed axis, and an end of this spring is fixed, the other end sticks into the inside groove of regulating parts, and the chucking face increases gradually along reverse counterclockwise point and the distance between the fixed axis.

Because the utility model has improved the chucking face, make its in the counterclockwise direction point and the distance between the fixed axis increase gradually, therefore longer when service time, behind the chucking surface wear, because the existence of spring, the chucking face will clockwise rotate, so that the distance between new contact position and the turning cylinder increases, thereby the chucking ability is further strengthened, and promptly the crystallized ability to safety belt strengthens, and has improved security and durability.

The specific embodiment

A kind of safety belt snap close, comprise lock frame 1, crossbeam 2 and regulate parts 3, regulating parts 3 and crossbeam 2 is fixed on the lock frame 1 abreast, the chucking face 7 of regulating parts is in axial direction tangent with crossbeam 2, regulate parts 3 and be fixed on the lock frame 1 by fixed axis 5, and be wound with the spring 4 that compresses on the fixed axis 5, an end of this spring 4 is fixed, the other end sticks into the inside groove 6 of described adjusting parts, chucking face 7 in the counterclockwise direction point and the distance between the fixed axis 5 increase gradually.When adjusting parts 3 counter clockwise directions were moved, the distance between chucking face and the crossbeam increased, and to adjust the degree of tightness of safety belt, feasible use is more convenient comfortable.Longer when service time, behind the chucking surface wear, because the existence of spring, the chucking face will clockwise rotate, so that the distance increase between new contact position and the turning cylinder, thereby the chucking ability is further strengthened, promptly the crystallized ability to safety belt strengthens, and has improved security and durability.

Claims

1. safety belt snap close, comprise lock frame (1), crossbeam (2) and adjusting parts (3), described adjusting parts (3) and crossbeam (2) are fixed on the lock frame (1) abreast, the chucking face (7) of described adjusting parts is in axial direction tangent with crossbeam (2), described adjusting parts (3) are fixed on the lock frame (1) by fixed axis (5), be wound with spring (4) on this fixed axis (5), one end of this spring (4) is fixed, the other end sticks into the inside groove (6) of described adjusting parts, it is characterized in that: described chucking face (7) in the counterclockwise direction point and the distance between the fixed axis (5) increase gradually.
