[0032] Referring to the drawings Figure 3As shown, further, the outer handle 12 is convexly formed with a rotating part 121 for synchronous rotation with the inner handle 11, and the connecting block 14 is arranged between the inner handle 11 and the outer handle 12 and synchronizes the rotation of the inner handle 11 and the outer handle 12, the connecting block 14 is formed with a fixing hole 141 for fixing the pull rope 3 and penetrating in the vertical direction, and the connecting block 14 is formed with a through hole 142 for the rotating part 121 to pass through and be clamped, wherein the fixing hole 141 and the through hole 142 are communicated, which facilitates fixing the pull rope 3 on the connecting block 14 during assembly and saves the time required for assembly.

[0033] It should be noted that the shape of the rotating part 121 is preferably polygonal, and the shape of the through hole 142 on the connecting block 14 is consistent with that of the rotating part 121, so that the connecting block 14 is clamped and matched with the rotating part 121 through the through hole 142, and the connecting block 14 synchronizes the rotation of the rotating part 121, thereby cooperating with the pull rope 3 to control the unlocking or locking of the lock body assembly 2.

[0034] Referring to the accompanying drawings Figure 4 As shown, in the embodiment, the outer side of the inner handle 11 is formed with a mounting recess 111, wherein the mounting recess 111 is mounted with a decorative cover 113; the mounting recess 111 is provided with a connecting screw hole 112 for connecting the rotating part 121 and penetrating, and by mounting the decorative cover 113 on the mounting recess 111, the overall aesthetic appearance is increased; secondly, the connecting screw hole 112 connects the clamping shell 13 and the inner handle 11 to the movable frame 4 through the pre-installed bolt, thereby increasing the connection stability of the clamping shell 13 and the inner handle 11 and the movable frame 4.

[0035] Referring to the accompanying drawings Figure 9 As shown, further, the clamping shell 13 is formed with a mounting part 131 for clamping and matching with the movable frame 4, wherein the mounting part 131 is formed with a mounting hole 134 for mounting the inner handle 11 and penetrating; the clamping shell 13 is formed with a primary positioning hole 132 for clamping and locking the inner handle 11 by the positioning pin and a primary fixing screw hole 133 for fixing the clamping shell 13 with the movable frame 4, specifically, the mounting part 131 on the clamping shell 13 is opposite; secondly, the positioning pin is clamped and matched in the primary positioning hole 132 formed on the clamping shell 13, thereby enabling the locking assembly 15 to realize the locking and unlocking functions of the inner handle 11; the primary fixing screw hole 133 is formed on the clamping shell 13, and the clamping shell 13 is fixed with the movable frame 4 by cooperating with the pre-installed bolt, thereby avoiding the clamping shell 13 from rotating with the inner handle 11 during daily use and affecting the user experience.

[0036] Furthermore, the locking assembly 15 includes a locking pin 151, a locking handle 152 connected to the locking pin 151, and a secondary torsion spring 153. The locking handle 152 has at least one, preferably two, locking blocks 1521 for locking the rotation of the inner handle 11. One end of the locking pin 151 has a locking boss 1511. Both ends of the secondary torsion spring 153 respectively abut against the inner side of the inner handle 11 and the locking boss 1511. The inner handle 11 has a locking recess 16 that mates with the locking assembly 15. The locking recess 16 has a through hole for the locking pin 151 to move back and forth.

[0041] Further, the lock body shell 21 is formed with a second positioning hole 212 and a third positioning hole 213 penetrating in the horizontal direction, and the contact end of the lock body shell 21 is provided with two rollers 26 for assisting the movement of the movable frame 4, thereby facilitating the movement of the movable frame 4 on the guide rail.

[0042] It should be noted that the second positioning hole 212 and the third positioning hole 213 are both provided with two connecting pins (not shown in the figure) matched with the first torsion spring 24 and the two clamping members 23, respectively; by matching the second positioning hole 212 with the connecting pin, the first torsion spring 24 is sleeved on the connecting pin of the second positioning hole 212, thereby fixing the position of the first torsion spring 24; secondly, by matching the third positioning hole 213 with the connecting pin, the two matched clamping members 23 are fixedly connected with the lock body shell 21, thereby enabling the clamping member 23 to clamp the guide rail.

[0043] For the convenience of explanation, the following further explains the specific working process of the random stopping door and window rope lock.

[0044] Unlocking mode: firstly, the locking block 1521 on the locking handle 152 is rotated and clamped to the unlocking groove 162, secondly, the outer handle 12 or the inner handle 11 is rotated, the pull rope 3 is driven to move the sliding piece 22 along the vertical direction to the relative position of the handle assembly 1, so that the two mutually matched clamping pieces 23 connected with the sliding piece 22 loosen the guide rail, and the movable frame 4 can freely slide on the guide rail, thereby completing the unlocking mode of the random stopping door and window rope lock.

[0045] Locking mode: after the movable frame 4 is moved to the desired position, the inner handle 11 is loosened, the connecting block 14 is rotated to the normal state, the sliding piece 22 is moved along the vertical direction to the relative position of the guide rail through the pull rope 3, and the elastic trend of the first-stage torsion spring 24 is matched to make the two clamping pieces 23 clamp the guide rail, so that the movable frame 4 is fixed at the position.

[0046] In addition, the locking block 1521 on the locking handle 152 is rotated and clamped to the locking groove 161, and the elastic trend of the second-stage torsion spring 153 is matched to make the locking pin 151 clamped to the first-stage positioning hole 132 of the clamping shell 13, so that the inner handle 11 is stopped and contacted with the clamping shell 13 through the locking pin 151, thereby completing the locking mode of the random stopping door and window rope lock.
