Therefore, during the transportation process, the goods must be bound and fastened, and there are many types of ropes, and most of the ropes are thick, and it is difficult to tie them manually. Therefore, they are often used on expressways. I saw all kinds of falling objects on the market. In view of this, there is a rope buckle structure on the market that can tighten and fix the rope. Using the use of the rope buckle, it can be wound in a way, and with the use of ratchets, The rope is gradually tightened. Its structure is mainly to install a rope shaft and a ratchet set between the two matable fixed seats and the movable seat. It is used to fix the ratchet group. The movable seat is also equipped with an elastic engaging plate for one-way pulling of the ratchet group or idling. The rope shaft can be retracted by pulling the movable seat so that the goods can be fixed by the rope. Usually, when the goods are tightened, the movable seat can continue to be pulled, because each person's strength is different, so the degree of tension is naturally different, and for people with strong strength, after the goods have been tightened, their total I think it can be pulled tighter, so I will always pull the movable seat and continuously tighten the rope. This method will not only easily cause the rope buckle to be overused and easily damaged, but also more likely to cause damage to the product, so This kind of structure that can continue to pull as long as there is strength is not as easy to use as expected, and there is still a lot of room for improvement.

The interlocking relationship of its structure can be observed from Figure 4 in conjunction with Figure 5. The safety locking plate 50 can move in the long slot 11 of the fixing seat 10, but is pushed by the spring 51 and normally engages the ratchet set 40. , so that the rope shaft 30 is limited to one-way rotation on the fixed seat 10, the control member 60 can move back and forth and up and down in the adjustment groove 22 of the movable seat 20, but is pushed forward and upward normally by the push of the spring 61 The control member 60 and the engaging plate 70 enable the engaging plate 70 to engage and engage the ratchet set 40, and the pushing plate 80 can move in the pressure regulating groove 21 of the movable seat 20, but is pushed against by the pressure spring 90. And before the normal state, the engaging plate 70 is pushed forward to deflect, thereby making the engaging plate 70 engage the ratchet group 40 with an angle and a force. When the movable seat 20 rotates along the ratchet group 40, the engaging plate 70 will yaw along the angle and move on the ratchet, but will not interfere with the ratchet group 40. When the movable seat 20 rotates against the ratchet group 40, the engaging plate 70 will push the ratchet group 40 to produce a lift. Rotate, thereby utilize the rope shaft 30 to retract the rope, and when the rope that the rope shaft 30 is retracted is tightened, the ratchet set 40 can be fixed by another position by the safety snap plate 50, so as to avoid the rope shaft 30 from coming into contact with the ratchet. The tooth set 40 is loosened, thereby repeatedly and continuously pulling the movable seat 20, so that the rope is tightened and gradually tightened, so as to obtain the purpose of binding the goods.

Please cooperate with Fig. 6 below, and after the rope is tightened to generate a preset pressure, if you continue to pull the movable seat 20, when you want to use the engaging plate 70 to engage the ratchet set 40, the original push The pushing plate 80 of the engaging plate 70 can no longer push the engaging plate 70 forward, but will cause the engaging plate 70 to shift, so that the purpose of pulling the movable seat 20 can not continue to tighten the rope. The tensioned preset size of the aforesaid rope depends on the adjustment hole 23 screwed on the pressure regulating button 91, so that the pressure spring 90 pushes against the push plate 80. The greater the pressure, the greater the thrust produced on the engaging plate 70, so the rope can be pulled tighter; on the contrary, the smaller the pressure produced by the compression spring 90 on the pushing plate 80, the greater the force on the engaging plate 70. The thrust of the rope is also relatively small, so the rope after pulling is relatively loose.

The tension of the rope is adjusted as shown in Fig. 7, which is to utilize the pressure regulating knob 91 set in the adjustment hole 23 by turning the screw, and use the pressure regulating knob 91 to change the pressure produced by the pressure spring 90 on the pushing plate 80 , when the pressure regulating button 91 is screwed deeper, the pressure spring 90 is more compressed, the greater the thrust applied to the engaging plate 70, the tighter the rope that is rolled up, and vice versa.
