Description

Strap Adjustment

The invention relates to a rope control device, in particular to a rope elastic adjustment device which can tighten and loosen the rope.

In recent years, the tightness between the blocks of clothing, shoes, bags, fabrics and other related products is adjusted by punching holes and pulling the ropes through the holes and then tying them. However, this method is inconvenient to adjust the tightness and has the problem of being easily loosened.

Therefore, the object of the present invention is to provide a device which can at least overcome the disadvantages of the prior art.

Therefore, the novel strap tension adjustment device can be installed on a surface to tighten a strap, and comprises a mounting seat unit, a winding seat unit, an outer ring seat unit, an inner ring seat unit, and a cover unit.

Referring to FIG. 1 , FIG. 3 , and FIG. 4 , after the mounting seat unit 2 , the winding seat unit 3 , the outer ring seat unit 4 , the inner ring seat unit 5 , and a cover unit 6 are assembled and combined in sequence, they can be switched between a locked state and a loosened state.

When in the locked state, the axial annular wall 62 of the cover unit 6 is engaged with the inner ring seat unit 5, and each latching strip 623 of the axial annular wall 62 is inserted into the corresponding limiting groove 515 of the inner ring body 51, and each of the check blocks 624 is engaged with the corresponding check rib 514.

The inner ring seat unit 5 is against the side of the limit ring 43 of the outer ring seat unit 4 near the cover unit 6, and the limit blocks 513 are simultaneously clamped against the side of the limit ring 43 near the mounting seat unit 2, the inner ring check block 523 of each elastic arm 52 is hooked on the outer ring check tooth 48, and the extension column 32 of the winding seat unit 3 protrudes into the axial ring wall 62 of the cover unit 6, and each winding tooth 322 of the extension column 32 is respectively connected with the corresponding each of the axial ring wall 62. The axis clamping tooth 625 is engaged, and the limiting plate portion 312 of the winding body 31 adjacent to the outer ring seat unit 4 is abutted against the limiting ring 43 adjacent to one side of the mounting seat unit 2, and a matching rope is inserted into the threading holes 313 on the winding body 31 of the winding seat unit 3. In addition, the clamping plate 44, the first limiting block 45, the second limiting block 46 and the clamping columns 47 of the outer ring seat unit 4 are respectively clamped in the corresponding first limiting groove 211, the second limiting groove 212, the clamping plate groove 221, and the clamping column groove 222.

In this state, the user can rotate the cover unit 6 to drive the winding seat unit 3 to rotate, and the rope is continuously wound around the shaft surface of the winding seat unit 3 to achieve a locking state.

When switching to the loosened state, the user pulls the cover unit 6 away from the mounting base unit 2. After pulling, the inner ring base unit 5 is simultaneously pulled away from the outer ring base unit 4, so that the winding protrusion 322 of the extension column 32 of the winding base unit 3 and the axial clamping teeth 625 on the inner shaft wall 622 are in a non-engaged state. At the same time, the cover clamping block 633 of the cover unit 6 is now clamped against the check ring 42 of the cover unit 6. Under the premise that the cover unit 6 will not fall off, the rope can be pulled freely to achieve the loosening effect.

The present invention particularly extends the column 32 and the winding body 31, and the axial ring wall 62 and the cover plate 61 to be designed as an integrated state, thereby reducing the number of parts to make the structure assembly more convenient. In summary, the present invention can indeed achieve the purpose of the present invention.

However, the above is only an example of the implementation of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the present patent.
