Description

Technical Field

[0001] The utility model belongs to the field of lock devices, in particular to a cable lock with a lock core. Background Art

[0002] One of the main functions of the cable lock is to provide high-strength support. It is made of solid metal and can withstand significant tension in various environments, which makes it an indispensable equipment in the fields of industry, construction and outdoor activities. In activities such as high-altitude operations and mountaineering, safety cable locks can be used to prevent falling accidents. By properly tying the cable, people can always stay safe when working or moving at heights. Safety cable locks can also be used in emergency rescue situations. When someone is trapped in a high-rise building, cliff or other high place, rescuers can use safety cable locks to perform rescue operations and safely lower the trapped person.

[0003] However, the existing grip-type safety cable lock is unlocked by hand grip and locked by releasing the hand. During use in activities such as aerial work and mountain climbing, due to operational errors, the unlocking handle may be accidentally touched by walls of high-rise buildings, rocks on cliffs or other protrusions, which may easily cause the cable to loosen and fall, endangering the life safety of the user.

[0004] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0026] The utility model will now be further described in detail with reference to the accompanying drawings.

[0027] See also Figure 1-5 As shown, in this embodiment, a cable lock with a lock core is provided, comprising a shell 1, the shell 1 is provided with a cable storage and bundling opening 4, and the side of the shell 1 is provided with a channel outlet 5, a key entrance 6, a cable entrance 7, and a channel entrance 8; the cable storage and bundling opening 4 is used to store excess cables outside the bundling lock;

[0028] A lock cylinder 16 is installed in the shell 1 near the key entrance 6, and a rotating shaft 12 is installed at one end of the lock cylinder 16. A locking guide rail 10 is provided in the shell 1 near the channel outlet 5, and a cable locking member 11 is installed in the locking guide rail 10. A cable channel 9 is provided in the shell 1 near the channel entrance 8, and a travel clamp lock block 17 is installed in the middle of the cable channel 9. A slide groove 13 is provided on the side of the inner wall of the shell 1 near the channel entrance 8, and a travel component 14 is installed in the slide groove 13; the travel clamp lock block 17 is a push-type buckle switch.

[0029] The application of one aspect of this embodiment is as follows: the key is inserted into the lock cylinder 16 and rotated, the lock cylinder 16 rotates and drives the rotating shaft 12 to rotate to a parallel position, the finger presses the stroke component 14 and moves it along the direction of the stroke clamp lock block 17 to the stroke clamp lock block 17, and is stuck and immovable under the action of the stroke clamp lock block 17, and at the same time the stroke component 14 squeezes the cable locking piece 11 to separate it, the cable enters the cable channel 9 from the channel entrance 8, passes through the cable locking piece 11 and the channel exit 5 in turn, and is pulled down to the desired position, and then the stroke component 14 is pressed to release the travel clamp lock block 17 from limiting the stroke component 14, so that the stroke component 14 is reset to its initial position, and at the same time, the limit of the travel component 14 on the cable locking member 11 is released, so that the cable locking member 11 clamps the cable upward along the locking guide rail 10, and then the key is rotated and pulled out, so as to achieve the locking purpose. In this state, the cable can only be tightened but not loosened. The locking and unlocking of the cable is controlled by the travel component 14 in conjunction with the lock core 16, which is convenient and practical, and easy to operate. The travel component 14 is unlocked in conjunction with the lock core 16, which improves the stability of the locked cable and is conducive to avoiding accidental touching of the unlocking handle due to operational errors during use, which may cause a falling accident caused by the loose cable.

[0030] See also Figure 1-4 As shown, the stroke assembly 14 of this embodiment includes a slider 1401 that slides in the slide groove 13, a stroke block 1402 is installed on the side of the slider 1401, a buckle head 1403 is installed on one side of the stroke block 1402, a return spring 1404 is installed between the stroke block 1402 and the cable channel 9, and the return spring 1404 is located on both sides of the buckle head 1403; two limit blocks are arranged on the stroke block 1402, and a limit gap that matches the rotating shaft 12 is formed between the two limit blocks, and the two limit blocks are provided with inclined surfaces that match the cable locking piece 11, and the buckle head 1403 is adapted to the stroke clamp locking block 17.

[0031] Through the travel component 14, the key is inserted into the lock core 16 and rotated. The rotation of the lock core 16 drives the rotating shaft 12 to rotate to a parallel position, releasing the limit of the rotating shaft 12 on the limit block. When the finger presses the travel block 1402, under the action of the slider 1401 and the slide groove 13, the travel block 1402 moves along the direction of the travel clamp lock block 17, so that the buckle head 1403 moves into the travel clamp lock block 17, so that the buckle head 1403 is locked by the travel clamp lock block 17. At this time, the rotating shaft 12 is located in the limit gap formed between the two limit blocks. At the same time, the inclined surface of the limit block squeezes the cable locking piece 11 to separate them. In this state, the cable can be Move, when the travel block 1402 is pressed again, the lock of the travel clamp lock block 17 on the buckle head 1403 is released, and under the action of the reset spring 1404, the travel block 1402 is reset, and at the same time, the squeezing of the cable locking piece 11 by the inclined surface of the limit block is released, so that the cable locking piece 11 is reset and clamps the cable, and then the key is rotated to rotate the lock cylinder 16 to drive the rotating shaft 12 to reset, so that the rotating shaft 12 limits the limit block. In this state, the travel block 1402 is pressed, and the moving distance of the travel block 1402 is limited. The inclined surface of the limit block cannot squeeze the cable locking piece 11, thereby solving the problem of cable loosening due to accidental touching of the travel block 1402.

[0032] See also Figure 1-3 As shown, the cable locking member 11 of this embodiment includes a locking block 1101 that is slidably fitted in the locking guide rail 10, and a force spring 1102 is provided between the locking block 1101 and the locking guide rail 10; there are two locking blocks 1101 in total.

[0033] Through the cable locking piece 11, when the inclined surface of the upper limit block of the travel block 1402 squeezes the locking block 1101, the two locking blocks 1101 slide downward along the locking guide rail 10, so that the two locking blocks 1101 are separated and the lock of the cable is released; when the inclined surface of the upper limit block of the travel block 1402 does not squeeze the locking block 1101, the force spring 1102 drives the locking block 1101 to clamp the cable upward along the locking guide rail 10, thereby locking the cable.

[0034] See also Figure 1-5 As shown, the rotating shaft 12 and the lock core 16 of this embodiment are mutually provided with a semicircular protrusion 18 to realize the synchronous rotation function; through the provision of the semicircular protrusion 18, when the lock core 16 is rotated by the key, the semicircular protrusion 18 on the lock core 16 rotates to drive the semicircular protrusion 18 on the rotating shaft 12 to rotate, thereby controlling the position of the rotating shaft 12.

[0035] See also Figure 1-2 As shown, in this embodiment, a mounting frame 15 is disposed in the housing 1 between the cable inlet 7 and the rotating shaft 12; the mounting frame 15 is used to install a fixing seat for the cable.

[0036] See also Figure 1-2As shown, the housing 1 of this embodiment includes a lower shell 2 and an upper shell 3 that matches the lower shell 2; the lower shell 2 and the upper shell 3 are fixedly connected, so that the lock cylinder 16, the rotating shaft 12, the locking guide rail 10, the cable locking member 11, the cable channel 9, the travel clamp lock block 17, and the travel assembly 14 can be limitedly assembled between the lower shell 2 and the upper shell 3.
