Optionally, the limiting section is a clicking hook installed in the lock body so that it presses against the top side edge when the spring force is greater than external force; the elastic structure is a spring.
In the present invention, a hollow bolt is installed through female restraining string base using bolted method for connecting cloth element and bottom board and installing protruding blocks on the binding surface of connecting cloth for assistance of pressing against the surface of cloth element for enforcing the binding intensity of female lock and cloth element. This is for stable positioning and thereon increases the operating feature and durability of the string locking device.
The present invention proposes a string locking device and its female lock, wherein the main feature is in the female lock restraining string base is installed with hollow bolt, using bolting method to combine with cloth element and bottom board. The binding surface for connecting with cloth element is installed with protruding blocks for assistance of pressing against the surface of cloth element, wherein the female lock and cloth element could provide high binding intensity to provide female lock with stable positioning.
Below connecting instruction with attached diagrams provides detailed description for the embodiment of the present invention. Clearly, the embodiment described is one of the embodiments of the present invention. The embodiments obtained by those skilled in the art under the pretext without paying creativity are protected by the claims of the present invention.
Please refer to
The female lock 50 installed on cloth element 90 consists of a string restraining base 30 and a bottom board 40. The string-restraining base 30 comprises a main body 31 and a hollow bolt 36, wherein the main body 31 is installed with a hollow shell of assembly grove 32 with a binding surface 310 for binding the cloth element 90. The top of binding surface 310 is installed with a front opening hole 33, wherein the front opening hole 33 penetrates the two opposing walls of the assembling grove 32 of the main body 31. The top of binding surface 310 is installed with multiple cone shaped protruding blocks 34 circularly installed on the surrounding of front opening hole 33. The hollow bolt 36 is a copper bolt coupled to the main body 31 and connected to front opening hole 33, vertically extended from the binding surface 310 towards exterior of main body 31. The bottom board 40 in general is presenting a plate structure, wherein the top is installed with a binding hole 41 for receiving the penetrating installation of hollow bolt 36. The bottom board 40 has an individual binding surface 42 for binding cloth element 90. The binding surface 42 is also installed with multiple cone-shaped protruding blocks 43 circularly installed on the surrounding of binding hole 41.
Additionally the main body 31 of the restraining string base 30 and the bottom board 40 in general is made of plastic injection art, whereas the binding method of hollow bolt 36 and main body 31 is compressed together, or bound through combined injection of hollow bolt 36 and main body 31 so that the hollow bolt 36 is embedded directly in main body 31.
The restraining string base 30 and bottom board 40 are connected to the opposing surface 91 and 92 of binding cloth element 90, respectively for the hollow bolt 36 to be installed on the binding hole 41 through the hole 93 of cloth element 90. The hollow bolt 36 penetrating hollow bolt 41 is bound to the binding hole 41 using compressed and rotated method for connecting to bottom board 40. The protruding block 34 of restraining string base 30 and the protruding block 43 of bottom board 40 respectively press against the surface 91 and 92 of cloth element 90, which assist intensifying the binding strength to stabilize the positioning of female lock 50.
The elastic structure 60 is a spring installed at the bottom of assembling grove 32. The male lock 20 has an activating section 21, a lock body 22, and a limiting section 24. The top of lock body 22 is installed with a male lock hole 23, wherein the size of the hole and direction of opening matches with the front opening hole 33 and direction of restraining base 30. The activating section 21 is presenting a curving structure installed on the top of the lock body 22, wherein the limiting section 24 is a clicking hook installed on the lock body 22. The male lock 20 is installed on the assembling grove 32 of restraining string base 30 so that the bottom surface 25 of the lock body 22 presses against elastic structure 60 in order to receive its pressing spring force while the limiting section 24 presses against the edge of front opening hole 33.
When the male lock 20 receives spring force, the male lock opening hole 23 drifts away the front opening hole 33, the limiting section 24 presses against the top side edge of front opening hole 33 so that the male lock 20 is restrained inside the assembling grove 32. When the activating section 21 of male lock 20 is subjected to external force F, the lock body 22 is pressed against the elastic structure 60 and sunk into assembling grove 32 until the limiting section 24 is pressed against the lower side edge of the front opening hole 33, the male lock opening hole 23 is pointed to front opening hole 33 while and form a penetrating path 11 with bolt 36 that for string to pass through. When the external force F is removed, the male lock 20 returns to the original position so that the male lock opening hole 23 drifts away the front opening hole 33, causing the penetrating path 11 to reduce, thereafter achieves the locking function for the string.
Lastly to explain in particular is, in the embodiment of the present invention, the protruding blocks 34 and 43 is using cone-shaped protruding blocks forming circular arrangement as an example. In other embodiment the protruding blocks can be designed into any suitable shape structure and arranged in any forms that similarly achieves the effect of assisting in positioning.
In summary, the present invention of string locking device and its female lock through installing hollow bolt in the female lock restraining base adopts bolting method for connecting with cloth element and bottom board, and through the binding surface of cloth element additional protruding blocks are additionally installed pressing against the surface of cloth element for the aid of positioning Therefore, the binding intensity of female lock with cloth element will effectively increase, rendering the string locking device steadily positioned, thereby helps in increasing its operating feature and durability.
Above is just the preferred embodiment of the present invention. However, the claims of the present invention are not limited here. Those skilled in this art could easily make numerous modifications and variations without departing from the scope and spirit of the invention set forth in the claims.
