The present invention relates to a strap locking device for fixing in place and bundling of cargo or goods for storage and transportation.
The current existing strapping devices for transit poses several problematic issues and limitations. The force used may result in the deformation of loose items. Furthermore, as the current strapping devices do not maintain proper tension, it requires constant re-tightening during use. For example, the most common strap locking means used is where the strap is wound around a rotating shaft, one end of the rotation shaft fixed to the bracket, the rotation shaft of the traction device, the rotation axis of the string connected with the ratchet, and the spring clutch, wherein between the ratchet and the rotary shaft is fixedly connected to a rotating shaft rotatable clutch, the clutch spring against the ratchet wheel, the torsion spring is provided between the holder has a pawl and bracket with the clutch detent bumps and grooves. Due to structural reasons, such a strap locking means during transit will become loose and requires repeated tightening due to frictional forces on the device. This makes the use of the device inconvenient or impractical. Furthermore, while the strap is wound between the ratchet shafts, the ratchet pawl control member and the strap and other operations within the same housing is prone to failure due to winding.
The objective of the present invention resolves the above-described technical problems in present strapping devices and to provide a convenient handling, customizable means to secure cargo and goods for storage and transportation.
The technical solution of the present invention is: A strap locking means, which includes a bracket and a strap, one end of the other end of the catch strap, the strap is wound around a rotating shaft, the rotating shaft is fixed on the holder, one end of the rotary shaft protruding on the side bracket, the bracket is extended beyond the rotation axis of the torsion spring at the end cap, the end cap is connected in a torsion spring and the tightening of the torsion spring between the rotary shaft, wherein said rotation the other end of the shaft projecting on the other side of the bracket, the rotation shaft extending beyond the bracket into the outer bracket, connected in series with a ratchet wheel rotating shaft, the clutch cam and a spring, wherein there is a fixed connection between the ratchet and the rotary shaft, the clutch cam can rotate around the rotary shaft between the ratchet and the spring. The clutch is pressed against the action of the spring, an operation handle provided on the outer holder pinch, the pinch can rotate the clutch cam, and the outer torsion locking bracket acts against the force of the torsion spring locking pinch when rotated to the locking positions with a one-way ratchet clutch cam rotation operation handle, the lock overcomes the torsion force, to achieve the pinch-way ratchet locking and release of ratchet.
The invention strap locking means, is used by rotating the operation handle, the clutch cam is rotated to a position to pinch off the ratchet, the strap can be freely pulled out under the action of external force and when let go, it automatically tightens and then the clutch cam is rotated to the position of the pinch-way locking ratchet. This locking ratchet locking is unidirectional, only tighten the strap and will not loosen. At the same time, the ratchet wheel, the torsion spring, the locking trigger, and a control section is utilized to achieve a ratchet strap separation. Accordingly, the present invention is an adaptable, stable and reliable locking strap means.
