[0034] Please refer to Figure 1-Figure 5 , this embodiment provides a fall arrester lock 100, which includes a lock body 110, a movable buckle 120 and a limit assembly 130;

[0035] The lock body 110 is configured with a buckle portion 111 and a connecting portion 112. The buckle portion 111 is bent and configured to be hooked to an external safety component, and the connecting portion 112 is configured to be connected to a safety rope. The movable buckle 120 is movably connected to the lock body 110 and is in transmission connection with a limit assembly 130 connected to the lock body 110.

[0036] Among them, the limiting component 130 is used to drive the active buckle 120 to move relative to the lock body 110, and has a first position that allows the active buckle 120 to abut against the buckling part 111, thereby limiting the buckling part 111 from being disconnected from the safety part, and a second position that allows the buckling part 111 to be open.

[0037] Please refer to Figure 1-Figure 5 The working principle of the fall arrester lock 100 is:

[0038] During use, the fall arrester lock buckle 100 aims to ensure the safety of high-altitude operations. It can provide a stable connection for workers or equipment used in high-altitude operations to prevent them from accidentally falling off. During the hoisting process, it is first connected to the installation rope, and the safety rope is connected to the workers or operating equipment. It can be hung on an external safety component to ensure the connection between the workers or equipment and the safety component. The safety component can be an external safety structure during high-altitude operations.

[0039] Specifically, the fall arrester lock 100 includes a lock body 110, a movable buckle 120 and a limiting assembly 130; the lock body 110 is provided with a buckle portion 111 and a connecting portion 112, the buckle portion 111 is bent for hanging on an external safety member, and the connecting portion 112 is used to connect with the safety rope; the movable buckle 120 is movably connected to the lock body 110, and is transmission-connected to the limiting assembly 130 connected to the lock body 110; wherein the limiting assembly 130 is used to drive the movable buckle 120 to move relative to the lock body 110, and has a first position in which the movable buckle 120 abuts against the buckle portion 111, thereby limiting the buckle portion 111 from being disconnected from the safety member, and a second position in which the buckle portion 111 is open;

[0040] Thus, during use, the fall arrester lock 100 can be connected to the safety rope via the connecting portion 112. After the buckle portion 111 is hooked to the external safety component, the limiting assembly 130 can be used to limit the movement and position of the movable buckle 120 relative to the lock body 110, thereby preventing it from malfunctioning and causing it to fall off the safety component by mistake, thereby ensuring safety in use.

[0041] Therefore, the fall arrester lock buckle 100 can improve the stability of the hanging, avoid the accidental falling off, and thus improve the safety of high-altitude operations.

[0042] For further information, please refer to Figure 1-Figure 5 In this embodiment, in order to improve the convenience of use, when configuring the connecting part 112, the connecting part 112 includes a connecting hole opened on the lock body 110, and the connecting hole is spaced from the buckle part 111, thereby avoiding interference between the connection of the safety rope and the buckle part 111.

[0043] When configuring the active buckle 120, the active buckle 120 includes a sleeve 121 rotatably connected to the lock body 110. The sleeve 121 is configured with a supporting portion 122 for supporting the buckle portion 111. When the sleeve 121 is in a first position, the supporting portion 122 is supported against the buckle portion 111. When the sleeve 121 is in a second position, the sleeve 121 is sleeved onto the lock body 110. This arrangement allows the sleeve 121 to be in contact with the supporting portion 122 in the first position and to be sleeved onto the lock body 110 in the second position, thereby opening the buckle portion 111 and facilitating its connection or disconnection with the safety element for easy use.

[0044] When the limiting assembly 130 is configured, its function is to limit the movement and position of the movable buckle 120 relative to the lock body 110, preventing it from malfunctioning and causing it to erroneously fall off the safety member, thereby ensuring safety in use; specifically, the limiting assembly 130 includes a limiting rod 131, a limiting body 132, a driving unit 133, a transmission member 134, and a limiting member 135; the limiting rod 131 is connected to the ferrule 121, the limiting body 132 is connected to the lock body 110, the driving unit 133 is connected to the limiting body 132, the transmission member 134 is movably connected to the limiting body 132, and the limiting member 135 is rotatably connected to the lock body 110;

[0045] The driving unit 133 is used to drive the transmission member 134 to move relative to the limiting body 132, and drive the limiting member 135 to rotate relative to the lock body 110, and then abut against the limiting rod 131 to limit the rotation of the sleeve 121 from the first position to the second position.

[0046] Therefore, under the driving action of the driving unit 133, the transmission member 134 can be driven to move relative to the limiting body 132, and the limiting member 135 can be driven to rotate relative to the lock body 110, and then abut against the limiting rod 131 to limit the rotation of the sleeve 121 from the first position to the second position, thereby realizing the limiting effect on the position of the active buckle 120; and such a setting method can realize the active adjustment of the position of the active buckle 120 through the setting of the driving unit 133, thereby improving its convenience and intelligence in operation.

[0047] When the movable buckle 120 rotates, in order to avoid interference with the lock body 110, which would limit its rotation angle and affect its movement between the first position and the second position, the lock body 110 is provided with a clearance slot 113 for the limiting rod 131 to move.

[0048] For further information, please refer to Figure 1-Figure 5On the basis of the above structure, in order to enable the movable buckle 120 to return to the first position when not subjected to external force, the limiting assembly 130 further includes an elastic member 136. The elastic member 136 is connected to the lock body 110 and the limiting member 135, and is used to act on the clamping sleeve 121 through the limiting member 135, so that the clamping sleeve 121 has a tendency to move from the second position to the first position. In other words, this method adopts the method of applying an elastic force to the limiting member 135 through the elastic member 136, and then when the limiting member 135 is not subjected to external force, the elastic force of the elastic member 136 can make it contact with the limiting rod 131, thereby driving the movable buckle 120 to move from the second position to the first position.

[0049] In order to keep the limiting member 135 in contact or abutment with the limiting rod 131 during use, the limiting member 135 is provided with a limiting groove 137 abutting against the limiting rod 131. The purpose is to keep the limiting member 135 and the limiting rod 131 always in abutment with each other on the basis of the above structure.

[0050] To improve the convenience of operation, the drive unit 133 includes a movable rod 138 and a drive motor 139. The output end of the drive motor 139 is connected to the movable rod 138, and the transmission member 134 is in transmission connection with the movable rod 138. The drive motor 139 is used to drive the movable rod 138 to rotate, thereby driving the transmission member 134 to move. In other words, the drive motor 139 can drive the movable rod 138 to move, thereby driving the transmission member 134 and the limiting member 135 to move, thereby driving the movable buckle 120 connected to the limiting rod 131 to move, so as to adjust its position relative to the lock body 110.

[0051] It should be noted that in order to facilitate its operation, an operation button is provided on the lock body 110, so that the staff can control the working status of the drive motor 139. A remote communication structure can also be set up to enable the drive motor 139 to communicate and be remotely controlled with an external control center.

[0052] For further information, please refer to Figure 1-Figure 5 In order to detect the working state of the fall arrester lock 100, it is necessary to detect the relative position of the movable buckle 120. Based on this, the fall arrester lock 100 also includes a position detector 140, which is used to detect the position of the movable buckle 120 or the limiter 135. The position detector 140 can be a position sensor, which can determine the working state of the fall arrester lock 100 by monitoring the position of the movable buckle 120 or the limiter 135.

[0053] Based on the above-mentioned fall arrester lock buckle 100 , the present invention provides a high-altitude work fall prevention system, which includes the above-mentioned fall arrester lock buckle 100 .

[0054] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
