Abstract
The utility model relates to a self fastening telecopical fastener which can be optionally and telescopically adjusted. Extrusion positioning innovates by the method of a telescopic harness and a locking harness of the exiting solution knapsack, and the automatic locking can be conducted without the solution of the knapsack. An arc-shaped lock gear is arranged on a fastener plate of the self fastening telecopical fastener. When a shoulder harness is pulled, the lock gear is moved with the shoulder harness. The angulation changes, the gap distance changes to big, and the shoulder harness is naturally telescopic. When the shoulder harness stops pulling, the lock gear is reset and tightened by a base spring, and the shoulder strap is locked. When the shoulder harness is loosened, and the fastener plate is movably pressed, the fastener plate rotates around an oscillating shaft. The lock gear and a fastener casing and the shoulder harness naturally separate, and the shoulder harness can be freely adjusted. When the fastener plate is loosened, the base spring is contacted with the pressing plate, and the lock gear resets to the original position.
Description
The utility model relates to a kind of flexible bracelet, especially a kind of arbitrarily telescopic adjustment, the bracelet that automatic locking is pluged with molten metal.
At present known flexible bracelet is made up of not button, third gear button, fourth gear button, as flexible and padlock braces, and the knapsack of need loosening during use, the telescopic adjustment braces, its characteristics are locked and are pluged with molten metal braces.But this kind bracelet is to locate by twining the generation resistance with braces friction or curve, and in use easily loosening, arbitrarily telescopic adjustment and automatic locking are pluged with molten metal, and use the utmost point not nimble.
The utility model provides a kind of random telescopic adjustment, the buckle device that automatic locking is pluged with molten metal.
The utility model is achieved in that spring and tape spool are formed at the bottom of bracelet is by button shell, buckle, balance staff, buckle, forms extruding and locatees, and automatic locking is pluged with molten metal.The button shell is the main body that each parts is installed, and also plays the effect of pressing plate; Buckle is used for the padlock belt body and the belt body of loosening; Spring is used for buckle and resets and locate at the bottom of the buckle; Tape spool is used for fixing an end braces.Have arc lock tooth on the buckle, pressure is big because stress point is little for the arc tooth, and along with the effect of external force, pressure spot changes, be difficult for stabbing or the belt body that rubs (belt body is thrust in the stressed conference of pointed tooth, the damage braces; Flat tooth is stressed little, and belt body easily slides).Swinging axle (main shaft) is installed on the buckle, and balance staff forms a fixing distance with the cap of detaining on the shell, and before using, lock tooth on the buckle and cap coincide, when tightening up braces, as long as the pulling braces, the lock tooth is along with braces moves, angle changes, and spaces to become big, and braces is flexible naturally; After stopping drawstring, end spring resets the lock tooth and tightens up, and braces is promptly pluged with molten metal by lock.When loosening braces, as long as press buckle, buckle rotates around swinging axle, lock tooth and the development and change of cap angle, and the increase that thereupon changes of spacing, lock tooth, cap and braces natural separation this moment, and braces is scalable; Unclamp buckle, end spring withstands pressing plate, and the lock tooth is a homing.
Because adopt such scheme, knapsack need not to loosen, braces gets final product random telescopic adjustment and automatic locking is pluged with molten metal, and uses very nimble.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the side sectional view of first embodiment of the present utility model.
Fig. 2 is the side sectional view of second embodiment of the present utility model.
Fig. 3 is a basic vertical view of the present utility model.
Among the figure 1, braces.2, lock tooth.3, end spring.4, button shell.5, braces.6, tape spool.7, balance staff (main shaft).8, buckle.
In Fig. 2, braces (5) one ends are fixed on the tape spool (6).Pinch buckle (8) and will lock tooth (2) and open, send into braces (1) and insert and buckle in the shell (4), under the active force of end spring (3), buckle (8) drives lock tooth (2) and detains shell (4) mutual extrusion, is about to braces (1) certainly lock and plug with molten metal, and braces (1) can't be come off.When moving back band, lock tooth (2) is along with braces (1) moves, and angle also changes with spacing, and pressure increases, and lock tooth (2) is tightly locked and pluged with molten metal braces (1).When loosening braces (1), as long as depress buckle (8), lock tooth (2) is opened automatically, can braces (1) is flexible.When tightening up braces (1), only need buttress button shell (4) pulling braces (1) and can be tightened to desired location arbitrarily.
Claims (1)
- A kind of self-locking type bracelet that stretches, by the button shell and place the buckle, lock tooth, balance staff, the end spring that draw in the shell to form, it is characterized in that buckle by balance staff with detain shell and be connected, the buckle top is shaped on camber lock tooth, end spring places the buckle bottom, acts on buckle, and interlock lock tooth make-up shell produces pressure.
