Belt fastening device for belt binding {belt binding device for binding freight}

The present invention relates to a belt tightening device used to strap a cargo loaded on a vehicle with a belt. Particularly, the belt tightening belt for fastening a cargo strap provided with a double safety device by firmly fixing the tightening lever after finally tightening the cargo. Relates to a device.

In the conventional belt fastening device for cargo straps, a pair of latch wheels are rotated with a tightening lever to rotate a belt connecting rotary shaft on the latch wheel in one direction. At this time, the tightening lever is provided with a slider coupled to the teeth of the latch wheel. And a stopper is installed on the body side connected to the tightening lever to prevent the reverse rotation of the latch wheel, the stopper is to be separated from the teeth of the latch wheel when the tightening lever is rotated to the release position.

Therefore, in the conventional belt fastening device for cargo straps, when the tightening lever is rotated repeatedly, the rotating shaft for connecting the belt rotates in one direction, and the reverse rotation of the rotating shaft is prevented by the stopper. Therefore, the belt connected to the rotating shaft is wound on the rotating shaft, the tightening of the cargo occurs.

However, once the cargo is finally tightened in this way, the prevention of loosening of the rotating shaft is solely dependent on the first locking by the stopper.

Therefore, due to the nature of the cargo mounted on the vehicle, for example, if the shaking occurs with the vehicle, the tightening lever is not fixed and the tightening lever rotates around the axis of rotation. The belt is released and the cargo straps are released, which causes problems with transport safety.

The present invention has been made in view of the above circumstances, and the object of the present invention is to provide a belt fastening device for a cargo strap to secure a fastening lever after the final tightening of the cargo to provide a double safety device.

In FIGS. 1,2A and 2B, reference numeral 10 denotes a rotation axis.

The rotating shaft 10 has a perforated belt inserting hole 10a for inserting the end of the strap belt, and the belt inserting hole 10a is formed by dividing the rotating shaft 10 into two.

Latch wheels 12 and 12 are coupled to both ends of the rotary shaft 10, and latch wheels 12 and 12 are circularly coupled to the rotary shafts 12 and 12. Therefore, the rotating shaft 10 and the latch wheels 12 and 12 are rotatable integrally.

A tightening lever 20 for rotating the latch wheels 12 and 12 in one direction is connected to the rotation shaft 10.

The tightening lever 20 is left and right symmetrical is connected by the connecting bar 21 and the handle 22 on one side in the middle. Therefore, it is possible to repeat the rotation around the rotating shaft 10 by holding the handle 20.

The tightening lever 20 has a bearing part 22 having a shaft insertion hole 21a for inserting and supporting the rotary shaft 10 at one end thereof, and a cam part 23 protruding from the outer circumferential surface of the bearing part 22. Is provided, and the said handle 24 is rolled out at the other end. The tightening lever 20 is prevented from being separated from the rotating shaft 10 by the fixing pins 24 inserted into both ends of the rotating shaft 10.

At this time, the bearing portion 22 is disposed outside the latch wheels (12, 12).

The tightening lever 20 is provided with a slider 30 which is engaged with the tooth grooves of the latch wheels 12, 12.

The slider 30 is slidably coupled to the guide hole 20a formed on the opposite wall surface of the tightening lever 20, and the slider 30 is pushed toward the latch wheels 12 and 12 by the spring 32. The one end of the torsion spring 32 is supported by the tightening lever 20 and the other end is supported by the slider 30. At this time, the sliding direction of the slider 30 is the radial direction of the rotary shaft 10, and pull the slider 30 by holding the handle 22 of the tightening lever 20 and pulls the slider 30 to end the latch wheel 12, It is to be separated from the tooth groove of 12).

Therefore, when the tightening lever 20 is repeatedly rotated at a predetermined angle, the latch wheels 12 and 12 are rotated in one direction while the ends of the slider 30 are locked to the tooth grooves of the latch wheels 12 and 12.

In this state, when the tightening lever 20 is rotated to the original position, the end of the slider 30 passes over the toothed surfaces of the latch wheels 12 and 12 so that the latch wheels 12 and 12 rotate together with the rotation shaft 10. It is not supposed to be done.

In addition, a stopper support bracket 40 is connected to the rotary shaft 10 to the inside of the latch wheels 12 and 12.

One end of the stopper support bracket 40 is formed with a shaft support portion 42 having a shaft support hole 42a for insertion rotation support of the rotation shaft 10, as shown in Figure 4a, 4b.

On the outer circumferential surface of the shaft support part 42, the first first stop jaw 43a and the second final stop jaw 43b for limiting the tightening rotation of the tightening lever 20, and the release after the tightening of the rotary shaft 10 are performed. The unlock groove 44 for holding the position and the safety locking groove 45 for holding the fixed position after tightening the rotary shaft 10 is provided.

That is, when the tightening lever 20 is to rotate the rotation shaft 10 in one direction, the tightening lever 20 is operable within the rotation section of the first first stop jaw 43a and the second final stop jaw 43b.

In this case, preferably, the safety locking groove 45 is formed at a position to be engaged with the slider 30 when the tightening lever 20 reaches a pivoted position until the tightening lever 20 overlaps the stopper support bracket 40 as shown in FIG. 3A. This is good. That is, the safety locking groove 45 is preferably formed near the first initial stop jaw (43a).

This is to enable the compaction of the belt tightening device after the binding of the cargo and further to prevent interference with the tightening operation of the tightening lever 20.

And the depth of the safety locking groove 45 for locking the slider 30 is preferably extended to the tooth groove of the latch wheel (12, 12).

This is to prevent the reverse rotation (direction in which the rotation shaft 10 rotates when the tightening belt is released) by the latch wheel 12 and 12 primarily by the stopper 50 to be described later and the slider 30 secondly. to be.

The other end of the stopper support bracket 40 is connected to the connecting bar 46, the connecting bar 46 is connected to one end of the fastening belt 47, the other end of the fastening belt 47 is connected to the hook ( 48 or the connecting ring 49 is connected.

The stopper 50 is provided on the center opposite wall surface of the stopper support bracket 40 to prevent reverse rotation of the tightened rotating shaft 10.

The stopper 50 is slidably coupled to the guide hole 41 formed on the sidewall of the stopper support bracket 40 and at the same time, one end of the stopper 50 is pushed into the tooth groove of the latch wheel 12 and 12 by a spring 52. have. One end of the spring 52 is fitted to the spring hanger shaft 52a of the stopper 50 and the other end is supported by the spring receiving portion 42 of the stopper support bracket 40.

Therefore, the stopper 50 passes over the curved surfaces of the latch wheels 12 and 12 when the tightening lever 20 is rotated in the tightening direction, and the latch wheels 12 and 12 when the tightening force is applied to the rotation shaft 10. Is caught on the engaging surface of the tooth groove.

The operation of this embodiment configured as described above will be described.

3b shows the initial operating position of the tightening lever 20. At this time, the slider 30 is engaged with the tooth grooves of the latch wheels 12 and 12 in a state where it is located on the first stop jaw 43a.

In this state, when the tightening lever 20 is rotated in the direction of the arrow, the latch shaft 12 and 12 are bitten and the rotating shaft 10 is rotated in the belt tightening direction.

At this time, since the stopper 50 rides over the curved portions of the latch wheels 12 and 12, the stopper 50 does not interfere with the winding rotation of the latch wheels 12 and 12. However, the stopper 50 prevents the latch wheels 12 and 12 from rotating backwards.

The position at which the tightening lever 20 can be rotated to the maximum is the moment when the slider 30 touches the second final stop jaw 43b as shown in Fig. 3C. In this embodiment, the tightening lever 20 can be rotated up to 150 degrees. 3c shows the final operating position of the tightening lever 20.

Therefore, when the tightening belt is connected to the belt insertion hole 10a of the rotating shaft 10, the tightening belt is pulled.

The reason why the tightening lever 20 can be rotated to the original position is that the slider 30 can ride over the toothed curved portions of the latch wheels 12 and 12.

When the tightening lever 20 is repeatedly rotated as described above and the tightening belt is finally tightened, the tightening lever 20 is not fixed between the first first stopping jaw 43a and the second final stopping jaw 43b. Thus, for example, the tightening lever 20 is rotated when the vehicle is moving.

Therefore, the present invention, after fully tightening the tightening belt with the tightening lever 20, if the slider 30 is inserted into the safety locking groove 45 of the stopper support bracket 40 as shown in FIG. 3a, the tightening lever 20 is no longer tightened. Will not be able to move.

That is, when the slider 30 is fitted into the safety locking groove 45 of the stopper support bracket 40, the tightening lever 20 is stacked with the stopper support bracket 40 and one body as shown in FIG. 3A, and simultaneously the slider 30 is provided. Is hooked to the tooth groove of the latch wheel (12, 12).

Therefore, the slider 30 and the stopper 50 are simultaneously caught by the teeth of the latch wheels 12 and 12 at the same time even if the vehicle is shaken while moving after the vehicle is bound to the cargo using the device. As a result, the rotation shaft 10 is not loosened, and the tightening lever 20 does not swing around the rotation shaft 10.

In addition, the locking lever 20 is securely in the position of the lock, so that the locking is not inadvertently released unless the user intentionally releases the locking of the slider 30.

On the other hand, if you want to loosen the straps of the cargo, grab the handle 22 of the tightening lever 20, pull the slider 30 to be located in the unlock groove 44 of the stopper support bracket 40, as shown in Figure 2a The cam lever 23 of the tightening lever 20 pushes up the stopper 50 so that the teeth of the stopper 50 and the latch wheels 12 and 12 are released.

Therefore, the rotation shaft 10 integrally with the latch wheels 12 and 12 is free to rotate in any direction, thereby releasing the tightening force of the tightening belt.

As described above, the belt binding device of the present invention has the same binding action as in the related art, but in particular, after tightening the tightening belt, the fastening lever 20 can be locked to the added safety locking groove 45 so as to stop the stopper 50. Next, a double safety device is provided.

That is, sudden release of the strap due to the unexpected release of the stopper 50 can be prevented.

In addition, since the tightening lever 20 is folded into the stopper support bracket 40 and one body after the strap, the binding device is compact, and the user can easily visually determine the locked state.

As described above, according to the belt fastening device for a cargo strap according to the present invention, since the latch wheel is double-locked structure, the safety is excellent, the compact posture can be taken after the strap, and the user can easily check the locking visually. That has the advantage.
