Description

  The present invention relates to a wire lock, and more particularly to a small wire lock whose length of a latch portion can be adjusted.

In a generally used small padlock, regardless of whether it is a steel cannula or a flexible steel rope, the length of the latch part is a fixed distance. For example, “Easy-to-open steel rope type padlock” disclosed in the Chinese patent No. 93214130 is a free end in which one end of the steel rope is fixed to the first side surface of the lock case and the other end can be inserted into the groove and the first doorway of the lock case. In addition, by controlling the opening and closing with a first lock mechanism provided in the lock case, a closed state is formed between the steel rope and the lock body, thereby providing a locking function. When locking, the free end must be placed in a fixed position on the side where the locking purpose can be achieved, so the area enclosed between the steel rope and the lock body follows the length of the steel rope that can only provide a fixed distance It will be. However, in general, this type of small padlock has a small volume and a limited distance. When it is necessary to lock two or more articles at the same time, or when the articles to be locked are relatively large, it is often the case that the enclosed area cannot provide a sufficient accommodation space. It is necessary to lock each using another lock. For example, not only must another lock be purchased, but also the time spent at the time of unlocking / locking is wasted, increasing the difficulty in use. If the length of the steel rope is increased in order to solve this drawback, the enclosing range may be too large and the locking effect may be reduced.
Taiwan Patent No. 93214130

  The structure of the above conventional padlock needs to lock its free end into the groove of the lock case and the first doorway when locking, and the other end is a fixed end, so it only encloses a predetermined range, The length of the latch portion cannot be adjusted according to the user's demand, and the range of use is limited.

The lock case 11 is provided with one upper case 110a and one lower case 110b that are installed facing each other, and one receiving recess 111 is provided on each side. The accommodation recess 111 is provided with a guide groove 119 leading to the inside. In the center of the lock case 11, there are provided a housing portion 112 and a relatively small diameter through hole 113 extending toward one end (end opposite to the latch portion A side). The housing portion 112 is provided with several through grooves 1121, the first column 114 is projected near the other end (the end of the latch portion A), and one second column 115 is provided on each side near the housing 112. Is protruding. In addition, several fitting holes 116 are provided in the vicinity of the peripheral edge of the lower case 110b so that the fitting holes 117 can be fitted to each other and firmly coupled to each other. Two lock holes 118 are provided through one end of the lock body 1 so that the end of the steel wire 2 can be passed therethrough.

  The numbering lock unit 13 is installed in the accommodating portion 112 of the lock case 11 and includes one numbering set 131 and one pressing piece 132. The numbering set 131 is a plurality of disk groups that are rotatably supported on a single central axis (coaxial) and numbered on the outer periphery, and the side periphery is a lock body so that the disk group can be rotated from the outside. One through groove 1121 is exposed. The numbering set 131 is configured such that the central axis can move in the axial direction only in a state where the numbers of the respective disks in a predetermined position are in a predetermined number sequence. The pressing piece 132 is suspended from one end of the central axis of the numbering set 131, and is configured to be capable of linear movement (linear movement in the axial direction) by being controlled by the numbering set 131 and the spring S1. When the numbering set 131 has an accurate numerical arrangement by controlling the elastic piece 133, the pressing piece 132 can be moved by the elastic force of the spring S1.

  The push button 14 is installed so as to face the housing recess 111 of the lock case 11, and is provided with a first guide member 141 and a second guide member 142 that extend vertically on both sides thereof. An inner end portion of the first guide member 141 forms a slope 1411. The first guide member 141 is provided with a notch portion 1412 through which the steel wire 2 can penetrate. A circular recess 144 in which the compression spring S <b> 2 can be installed is provided at the center of the push button 14, and the push button 14 can be moved in the housing recess 111 by its elastic force.

  The pressing member 15 has a V shape and includes a circular hole 153 so that the pressing member 15 can be fitted into the second pillar 115, and a first side piece 151 and a second side piece 152 are provided on both sides. The first side piece 151 is abutted against the pressing piece 132 of the numbering lock unit.

  The grip member 16 includes a circular hole 161 so as to be fitted to the first column body 114. The grip member 16 is provided with a groove portion 163 so that the second side piece 152 of the pressing member 15 can be pushed in and moved, thereby enabling a turning motion. In addition, a tooth row 164 is provided at the outer end so as to be engaged with the steel wire 2. One torsion spring S <b> 3 is fitted between the two grip members 16, and the legs at both ends of the torsion spring S <b> 3 abut against the inner side surface 162 of the grip member 16. Further, the tooth row 164 can be inserted into the lock hole 118 of the lock case 11 by the elastic force of the torsion spring S3.

  FIG. 4 is an explanatory diagram of the unlocked state of the present invention. First, the numbering set 131 of the numbering lock unit 13 is turned to the correct number. In this case, that is, when the pressing piece 132 is movable and the push buttons 14 on both sides of the lock case 11 are pressed, the first guide member 141 and the second guide member 142 can move inward along the guide groove 119. At the same time, the second side piece 152 of the pressing member 15 is pushed and swung around the second column 115 as the axis. At the same time, the grip member 16 is moved in conjunction with each other, and the tooth row 164 is detached from the position of the lock hole 118. At this time, the steel wire 2 can be provided through the lock hole 118, and after adjusting the latch portion A to the required length, the push button 14 is loosened and the usual elastic force is restored by the compression spring S2. Can be returned to position. At this time, the pressing member 15 is no longer abutted against the first guide member 141 and the second guide member 142, but the grip member 16 is pressed against the elastic force of the torsion spring S3 to expand, and the outer surface The tooth row 164 of the tooth is tightly biting the steel wire 2 and cannot be pulled out. Finally, when the numbers of the numbering set 131 are rearranged randomly, the pressing piece 132 becomes immovable and is abutted against the first side piece 151 of the pressing member 15. At this time, the pressing member 15 is in a predetermined position and cannot change its direction. Further, since the push button 14 cannot be pressed, the locking effect is achieved (see FIG. 5).

  As described above, the steel wire of the present invention can adjust the range of the latch portion according to the user's demand, and the length of the latch portion of the conventional padlock is insufficient, and it is necessary to use several padlocks. The inconvenience to do can be solved reliably. In use, it can be unlocked simply by pressing the push button, and the operation is quite easy.
