STATE OF THE ART

At present, lashing down the load with a lashing strap is supported by a belt tensioner. Because the length of the tie-down strap is at least 3m or 5m, such a long tie-down strap will be messed up if not used to tie down the cargo, making storage difficult and causing problems for later use of the strap tightener; Therefore, manufacturers have introduced a belt tensioner with a belt storage box. The belt storage box is integrated into the belt tensioner. The belt storage box is equipped with a mandrel, a movable lashing belt and a spiral spring on the inside. The potential energy can be released by the spiral spring to drive the mandrel to rotate, and then the movable lashing strap can be wound on the mandrel layer by layer, or the connecting end of the movable lashing belt can be pulled outward to drive the mandrel to rotate, so that the mandrel can also be used to synchronously drive the coil spring to store potential energy when the movable lashing strap is unwound in layers; At the same time, since the potential energy released by the spiral spring is continuous, for safety reasons, a locking element must be added to lock or release the potential energy of the spiral spring, but the current structural design of the locking element is inflexible, and it is mostly directly through Holding the movable lashing strap so that it cannot move, indirectly locks the coil spring to achieve the purpose that the coil spring cannot wind up the movable lashing strap even if the potential energy is released. Obviously, the locking structure is either full locking or full unlocking. In actual use, if it is necessary to pull out the movable lashing strap, then the opening of the locking member must be additionally controlled, which obviously leads to cumbersome and inconvenient use.

As in 1 until 2 1, a belt storage-capable lashing strap tensioner for assisting in lashing the cargo with a lashing strap comprises a fastening rod 1, and a ratchet lashing strap tensioner 2 and a belt storage box 3 attached to two ends of the fastening rod.

The ratchet lashing strap tensioning device 2 comprises a fastening element 21, a pivoting element 22 and a ratchet 23; The fixing member 21 is attached to the fixing rod 1, and in the fixing member 21 there is provided a latching member 24 which is elastically pushed and slides inward; The pivoting element 22 is internally provided with a stop 25 which is elastically pushed and slides inwards; The ratchet 23 consists of a ratchet shaft 231 and ratchet teeth 232 arranged at two ends of the ratchet shaft. A belt through hole 233 is provided on the ratchet shaft 231 . The ratchet shaft 231 is designed as two semi-shafts, and the belt passing hole 233 is formed right between the two semi-shafts.

The end of the fastening element 21 and the pivoting element 22 is articulated to one another via the ratchet shaft 23; When both the latch member 24 and the stop 25 engage the ratchet teeth 232, the pivot member 22 is actuated to continuously pivot relative to the fastener 21, thereby setting the ratchet 23 in unidirectional intermittent rotation about the movable lashing strap to wrap and stretch; When both the latch 24 and the stopper 25 are disengaged from the ratchet teeth 232, the ratchet 23 rotates, allowing the movable lashing strap to be freely pulled outward to facilitate lashing of the cargo.

The strap storage box 3 is internally provided with a mandrel 7, a movable lashing strap and a coil spring 9, and a connecting end of the movable lashing strap protrudes from the strap storage box 3 and passes through the ratchet lashing strap tensioner 2, in detail, through the strap-passing hole 233 on the ratchet shaft 23, through.

The belt storage box 3 consists of a left-hand shell 31 and a right-hand shell 32 which are snapped onto one another. From the left shell 31 and the right shell 32, mounting rods 1 extending parallel to each other extend, and a transverse shaft 11 is provided between the two mounting rods. A lashing strap should be attached to and connected to the transverse shaft.

On the belt storage box 3, there are provided end caps 6 attached to two end faces, that is, the two end caps are attached to the outside of the left shell 31 and the right shell 32, respectively; The hand wheel 4 is placed outside one of the end caps, in detail outside the end cap attached to the outside of the left shell, and the coil spring 9 is in the other end cap, specifically in the end cap attached to the outside of the right shell is, arranged; Thus, one end of the mandrel 7 located in the belt storage box 3 protrudes from the end cap 6, is drivingly connected to the hand wheel 4 and can rotate under drive from the hand wheel, while the other end of the mandrel 7 projects into the end cap 6 with which coil spring 9 and can rotate to drive the coil spring for storing potential energy, or rotated under drive from the potential energy released by the coil spring.

Two ends of the mandrel 7 are each provided with a flat shaft 71 drivingly connected to the handwheel 4 and a mounting groove 72 for installing the coil spring 9, while the outer surface of the mandrel 7 is provided with a belt attachment hole 73 extending axially extends so that after connection to the movable lashing strap, the coil spring 9 releases the potential energy to drive the mandrel 7 to rotate, thereby winding the movable lashing strap in layers on the mandrel for storage; In addition, when the potential energy released by the coil spring 9 cannot completely wind the movable lashing strap onto the mandrel 7, manual winding can be performed by the handwheel 4.

When the connecting end of the movable lashing strap is pulled outward, the mandrel 7 is driven to rotate, whereby the movable lashing strap is unwound in layers. At this time, the mandrel 7 also simultaneously drives the spiral spring 9 to store potential energy; In general, pulling the connection end outward means that the connection end is actively pulled outward directly through the belt passing hole 233 or the connection end is wound and pulled outward by unidirectional intermittent rotation of the ratchet 23 .

Furthermore, since the potential energy released from the coil spring 9 is continuous, a switch 5 must be provided outside the belt storage box 3 for safety reasons. The middle portion of the switch is rotatably attached to a rotary shaft 33 of the outer end face of the webbing storage box 3 . The lock hook 51 and a drive block 52 are formed at two ends of the switch 5, respectively, and by operating the drive block, the switch 5 can be rotated about the rotary shaft 33, whereby the lock hook 51 can be operated accordingly.

Both the locking hook 51 and the oblique hook 41 are composed of a hook back 101 and a hook tip 102, respectively the outside of the hand wheel 4. Now the coil spring 9 releases potential energy to drive the mandrel 7 so that the hook tip 102 of the locking hook 51 and the oblique hook 41 abut each other to limit the rotation of the mandrel 7. However, when the connection end is pulled outward, the hook back 101 of the locking hook 51 and the oblique hook 41 slides relative to each other, so that the rotation of the mandrel 7 is not restricted.

That is, the switch 5 is elastically pushed so that the locking hook 51 comes into abutment with the oblique hook 41 on the outside of the handwheel 4, whereby the rotation of the mandrel 7 driven by the potential energy released by the coil spring 9 can be restricted , but the turning of the mandrel 7 by pulling the connecting end outward is not restricted, thereby ensuring safe use without affecting the normal lashing or tension of the movable lashing strap; However, when the lock hook 51 is detached from the oblique hook 41 on the outside of the handwheel 4 by the switch 5, free rotation of the mandrel 7 is not restricted.

Further, the outer surface of the webbing storage box is provided with a sliding groove 34 extending in a circumferential direction, the driving block 52 of the switch 5 being exposed just inside the sliding groove 34; thus, by operating the drive block 52 to slide back and forth along the slide groove 34, the switch 5 can be rotated about the rotary shaft 33, bringing the locking hook 51 into abutment with the oblique hook 41 on the outside of the handwheel 4 or from the slanted hook on the outside of the handwheel is detached; Since under the influence of the torsion spring 8 under normal conditions the oblique hook 51 always comes into contact with the oblique hook 41 on the outside of the handwheel 4 through the switch 5, in order to detach the locking hook 51 from the oblique hook 41 on the outside of the handwheel 4, the The driving block 52 can be operated by external force to overcome the elastic force of the torsion spring 8, and then sliding along the sliding groove 34 is sufficient for this.

Obviously, the belt storage type tie-down tightener improved according to the above structure advantageously features clever structure design and convenient and flexible use.

So far, only one specific embodiment of the present utility model has been described. It will be understood by those skilled in the art that any design equivalent to this embodiment should be included within the scope of the utility model.
