[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0031] Reference Figures 1 to 4 To achieve the above objectives, this utility model proposes an easily adjustable anti-fall commutator, including a commutator body 1. The commutator body 1 is provided with an adjustment cavity 11, and a protective part 12 is provided opposite to the adjustment cavity 11. The protective part 12 surrounds the adjustment cavity 11. A commutation rail 2 is rotatably connected inside the adjustment cavity 11. The commutation rail 2 is slidably connected to the inner wall of the protective part 12. The protective part 12 is provided with a plurality of mounting parts 3 along the direction away from the commutation rail 2. The plurality of mounting parts 3 are arranged at equal angular intervals along the rotation direction of the commutation rail 2.

[0032] The mounting part 3 is provided with a mounting groove 31 facing the reversing rail 2. A movable rail 8 is provided in the mounting groove 31. The mounting part 3 is provided with a mounting structure 5 relative to the movable rail 8. The movable rail 8 is connected to the reversing rail 2.

[0033] The commutator body 1 has an adjustment cavity 11 inside, and a protective part 12 surrounds it. The adjustment cavity 11 allows the commutator rail 2 to be adjusted in position by rotation within the cavity. The protective part 12 surrounds the commutator rail 2. When a user enters the commutator rail 2 via the moving rail 8 using a fall protection device, the protective part 12 can restrict the fall protection device, effectively preventing the fall protection device from sliding out of the fall protection commutator when the commutator rail 2 is aligned with the moving guide rail. This structure can effectively improve the fall protection performance of the commutator and prevent safety accidents.

[0034] The reversing rail 2 is slidably connected to the inner wall of the protective part 12, which can effectively increase the contact area between the reversing rail 2 and the commutator. The reversing rail 2 can support the protective part 12 and improve the structural strength of the entire commutator. At the same time, the protective part 12 and the adjustment cavity 11 together wrap around the reversing rail 2, which can ensure the stability of the movement and fixation of the reversing rail 2 and prevent the reversing rail 2 from deviating. The reversing rail 2, the protective part 12, and the adjustment cavity 11 work together to effectively improve the structural strength of the entire commutator. The reversing guide rail can quickly and stably realize the reversing of the fall protection device.

[0035] The protection section 12 is provided with mounting sections 3 at equal angular intervals along the circumference of the commutator. The mounting sections 3 can be used to install and fix the moving rail 8. The moving rail 8 itself can be formed by an external rail extending into the mounting section 3. The mounting sections 3 are arranged at equal angular intervals, which can make the multiple mounting sections 3 evenly distributed, making the entire commutator structure stable and the entire commutation operation more stable. The mounting section 3 is provided with a mounting groove 31 for the moving guide rail to enter. The mounting groove 31 can better restrict the moving guide rail. At the same time, the mounting section 3 and the mounting groove 31 are used to set the mounting structure 5. The mounting structure 5 can fix the moving guide rail more quickly. The mounting structure 5 itself can be detachably connected to the mounting groove 31. This can make the design of each part easier. When it is necessary to install an external guide rail, the mounting groove 31 is used to limit the movement first, and then the mounting structure 5 is inserted to clamp the mounting groove 31 and the moving guide rail. This can achieve fast and stable installation of the commutator and ensure the structural strength of the commutator.

[0036] See also Figure 1 In one embodiment of this application, the mounting structure 5 is provided with fixing blocks 51 on both sides of the inner wall of the mounting groove 31, and the adjacent fixing blocks 51 are clamped together to form an installation space. The moving track 8 passes through the installation space, and the mounting groove 31 is provided with a locking structure 4. The locking structure 4 passes through the fixing blocks 51 and the moving track 8.

[0037] There are at least two locking structures 4, and the two locking structures 4 are arranged at intervals.

[0038] The mounting structure 5 includes two fixing blocks 51. Together, the two fixing blocks 51 can completely clamp the bottom of the moving track 8 through the mounting space formed by the clamping. The moving track 8 is a T-shaped track. When the two fixing blocks 51 clamp the bottom of the moving track 8, the distance between the two fixing blocks 51 is equal to the width of the mounting groove 31. The fixing blocks 51 can slide into the mounting groove 31 and can be completely limited by the locking structure 4, which can prevent the fixing blocks 51 from shaking and ensure the connection stability of the moving guide rail and the commutator.

[0039] At least two locking structures 4, formed by connecting two points, can ensure the stability of the locking.

[0040] See also Figures 1 to 3 In one embodiment of this application, the fixed block 51 is provided with an extension block 52 along the direction away from the mounting groove 31, the moving track 8 is connected to the extension block 52, and the extension block 52 is arrayed with a plurality of connecting structures 6 along the direction from the reversing track 2 to the extension block 52.

[0041] The connecting structure 6 passes through the adjacent extension block 52.

[0042] The moving track 8 may not be an external track, but a transfer track used to connect to the external track. In order to enable the external track to smoothly connect to the moving track 8, the fixed block 51 extends to have an extension block 52. The moving track 8 is connected inside the extension block 52. The extension block 52 is provided with multiple connecting structures 6. The connecting structures 6 have a similar function to the locking structure 4. The bottom of the external track passes between the two extension blocks 52. The connecting structures 6 are used to lock the extension blocks 52 together with the external track, which can ensure the structural strength.

[0043] See also Figure 3 In one embodiment of this application, the protection part 12 is provided with a relief cavity relative to the moving track 8, and the reversing track 2 is connected to the relief cavity.

[0044] The clearance cavity is provided corresponding to the mounting part 3. The clearance cavity facilitates the docking of the moving track 8 and the reversing track 2. At the same time, when the anti-fall device moves on it, it can enter or leave the reversing track 2 more smoothly, ensuring the smoothness of the reversing process and improving the user experience.

[0045] See also Figures 1 to 4 In one embodiment of this application, the reversing track 2 includes a stabilizing part 21 and a slide rail part 24. The bottom of the stabilizing part 21 is slidably connected to the adjusting cavity 11, and the outer periphery of the stabilizing part 21 is slidably connected to the protective part 12. The slide rail part 24 is connected to the stabilizing part 21, and a fixing part 22 is provided between the slide rail part 24 and the stabilizing part 21.

[0046] A fixing structure 23 is provided between the fixing part 22 and the adjusting cavity 11, and the fixing structure 23 and the adjusting cavity 11 are coaxially arranged.

[0047] The area of ​​the stabilizing part 21 is generally larger than that of the slide rail part 24. By increasing the contact area of ​​the adjustment cavity 11, the structural stability of the entire commutator can be significantly improved. The fixing part 22 is located in the middle of the commutation track 2, allowing the commutation track 2 to rotate freely within the adjustment cavity 11. The commutation track 2 itself can serve as a support structure for the commutator, improving its strength. The slide rail part 24 is connected to the moving track 8 and is used to dock with the fall protection device. The fixing part 22 is located between the slide rail part 24 and the stabilizing part 21. The fixing part 22 can be used to install a fixing structure 23, which can serve as the pivot of the commutation track 2. At the same time, the fixing part 22 ensures that the fixing structure 23 does not affect the slide rail part 24, guaranteeing the smooth movement of the fall protection device. The fixing part 22 also facilitates the self-locking of the fixing structure 23, preventing problems with the pivot of the commutation track 2 and ensuring that the commutator can operate more stably.

[0048] See also Figure 4 In one embodiment of this application, the fixing structure 23 is a bolt structure, which includes a screw and a nut. The screw passes through the reversing rail 2 and is connected to the fixing part 22. The nut of the screw is connected to the bottom of the adjusting cavity 11, and the nut is screwed to the screw and abuts against the stabilizing part 21.

[0049] The screw has a limiting part, which is located above the nut.

[0050] The fixing structure 23 itself is a bolt, and the nut of the screw is located at the bottom of the adjustment cavity 11, which can make the bottom surface of the commutator smoother, making the commutator easier to install and avoiding damage to the fixing structure 23 itself. The screw passes through the fixing part 22, and the nut is fixed on it, which can press the commutation rail 2, and at the same time make the fixing structure 23 itself easy to adjust.

[0051] The screw has a limiting part or a limiting hole above the nut. The nut can pass through the limiting hole when structure 5 is not installed. When the nut is locked, a locking component is set in the limiting hole. This component can lock the nut, ensuring the strength and stability of the rotating shaft of the reversing track 2, and effectively reducing safety hazards.

[0052] See also Figures 1 to 2 In one embodiment of this application, a limiting structure is provided in the adjustment cavity 11, the limiting structure is connected to one side of the mounting groove 31, and the stabilizing part 21 abuts against the limiting structure.

[0053] In this application, four mounting parts 3 are provided at equal angular intervals. Each mounting part 3 corresponds to a track in one direction. The four mounting parts 3 can be named the first track, the second track, the third track, and the fourth track. The first track corresponds to the third track, and the second track corresponds to the fourth track. When the reversing track 2 is connected to the second track, its other end will be connected to the fourth track. In order to ensure that the reversing track 2 can be quickly adjusted when the reversing device changes direction, a limiting structure needs to be set to ensure that the reversing device can switch from the connection of the first and third tracks to the connection of the second and fourth tracks, thereby effectively improving the reversing efficiency.

[0054] The limiting structure can be a limiting protrusion, which is located at the farthest end of two adjacent mounting parts 3, so that one end of the reversing track 2 can only move between the first and second tracks, the second and third tracks, the third and fourth tracks, or the first and fourth tracks, ensuring the rate of commutator adjustment and making the commutator itself easy to adjust.

[0055] See also Figures 1 to 3 In one embodiment of this application, the mounting groove 31 is detachably connected to a partition structure 7, the partition structure 7 surrounds the mounting groove 31, and the reversing track 2 is connected to one side of the partition structure 7.

[0056] All of the multiple mounting parts 3 of the commutator can be used and connected to different tracks, or only partially used. However, if a mounting part 3 is not connected to a track, its corresponding mounting slot 31 will be empty, which can easily lead to safety accidents. It is necessary to block the useless track. A partition structure 7 is set on the mounting part 3. The partition structure 7 is wrapped around the mounting part 3 and locked by a locking structure 4. The first locking is clamped. When the fall protection device enters the commutator track 2 through the third locking, the partition structure 7 will block the clearance cavity of the first locking, so that the fall protection device is restricted to the adjustment cavity 11, which can effectively reduce safety hazards and improve the user experience.
