Description

  The present invention relates to a cord lock, and in particular, when a pressing body is provided on a main body and is movably displaced in a fan shape, the through-hole of the pressing body and the through-hole of the main body are aligned or displaced so that the cord can be easily passed. At the same time, a pinching state in which the bite or release is realized.

  At present, in the form of locks for joining cords, straps or other articles, many of them are techniques such as elastic clamping, pressing fixation, displacement fixing and positioning through, and the purpose is adjusted through the cord Or used as a terminal anchor. In addition, it can be applied to bags or clothing, and most of the locks of the form described below are used when the cord is passed.

  Please refer to FIG. This is an exploded perspective view of a conventional cord lock. As is clear from the figure, the push button A is designed in a stepped shape, and a through hole A1 is provided in the central columnar body portion. A projection A11 that is an arcuate surface extends horizontally. When the fixed protrusion A2 protruding from the bottom end of the push button A is press-fitted into the upper edge of the spring C, and the diameter of the hole at the lower end of the spring C corresponds to the positioning protrusion B3 of the lock body B, The protrusion A11 of the push button A is pushed in along the two guide slopes B2 protruding from the upper end of the lock body B. Then, the through hole A1 and the two corresponding wall through holes B1 in the lock body B are made to coincide with each other, and after passing through both ends of a general cord, the spring C is pressed by the return elastic force after being compressed. The button A fixes the cord at the positions of the through hole A1 and the through hole B1.

  Therefore, as can be understood from the above, the conventional cord lock can be clamped and fixed so that the cord does not fall off, but the following inconvenience arises.

  (1) In the conventional code lock, a force is applied and pressed or released by a method in which a vertical force is generated between the push button and the lock body. In this case, since it is necessary to resist the process in which the push button enters the lock body and the reaction force of the spring, an increase in force when the user operates is caused.

  (2) In the conventional cord lock, a force is applied and pressed or released by a method in which a vertical force is generated between the push button and the lock body. When pressed, the coiled spring is compressed and overlapped, resulting in a certain height, so that the code lock becomes larger overall.

  (3) In the conventional cord lock, a force is applied and pressed or released by a method in which a vertical force is generated between the push button and the lock body. When pressing, the coiled springs are compressed and overlapped, resulting in a certain height and sometimes twisting, increasing the difficulty in aligning the push button and the through hole of the lock body.

The important points that the cord lock of the present invention can improve the prior art are as follows.

  (1) The urging means 3 according to the present invention relatively displaces the pressing body 2 and the main body 1 by pushing the two elastic arms 33 in a fan shape, and the structure design of the two elastic arms 33 is reliable. When it is pressed with an excessive positive force, the pressing force is dispersed by the two elastic arms 33, and the biasing means 3 is excessively pressed. The situation of deformation can be avoided.

  (2) Since the elastic arm 33 of the urging means 3 is displaced in a fan shape with a small angle, the pressing force operated by the user is reduced, the effect of the pressing process is improved and stability is provided, and the size is thereby reduced. This makes it easier for the user to operate.
