Description

Technical Field

[0001] This utility model relates to the field of rope release technology, specifically a rope release device with dual locking function. Background Technology

[0002] For example, a rope release device with patent publication number CN113562142A includes a front support panel and a rear support panel spaced apart. A triangularly distributed upper middle shaft, lower left shaft, and lower right shaft are mounted between the front and rear support panels. A left roller is fitted onto the lower left shaft, located between the front and rear support panels. A right roller is fitted onto the lower right shaft, also located between the front and rear support panels. A rope control plate, capable of rotating around the upper middle shaft, is fitted onto the upper middle shaft. The lower left corner of the rope control plate has a locking portion that engages with the left roller, and the lower right corner has a driving portion that engages with the right roller. A rope support reinforcement and limiting module is provided between the left and right rollers, detachably connected to the front and rear support panels respectively, abutting against the front and rear sides of the front and rear support panels to prevent the rope from collapsing downwards. This design is safer, more reliable, and easier to operate.

[0003] However, during use, the aforementioned equipment, due to the design of its internal front and rear support panels, cannot maintain the stability of the rope under extreme conditions due to the single locking device, thus reducing safety. Therefore, we propose a more convenient and practical rope reeling and releasing device to meet the usage requirements. Utility Model Content

[0004] The purpose of this invention is to provide a rope retractor with a double locking function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-locking rope retractor, including a connecting mechanism for connecting with a rope, a locking mechanism on one side of the connecting mechanism for locking the rope, the locking mechanism including a housing, at least three connecting blocks on one inner wall of the housing, a rotating shaft fixedly connected to one side of the housing, a winding reel rotatably connected to the outer wall of the rotating shaft, a groove on one inner wall of the housing, a locking piece slidably connected in the groove, the locking piece rotatably connected to the rotating shaft, and a locking assembly inside the winding reel.

[0006] Furthermore, the connecting mechanism includes a fixed ring, and a connecting ring is rotatably connected to the inner wall of the fixed ring.

[0007] Furthermore, a damping buckle is installed on one side of the connecting ring.

[0008] Furthermore, the locking assembly includes three islands that divide the inner wall of the reel into an inner channel and an outer channel.

[0009] Furthermore, a sliding post is fixedly connected to one side of the locking piece, and the sliding post slides along the three islands.

[0010] Furthermore, a slot is provided on one side of the outer shell, and an enlarged head is slidably connected inside the slot. A connecting rod is fixedly connected to the outer wall of the enlarged head, and a pull ring is fixedly connected to one end of the connecting rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This dual-locking rope reel works by using a connecting and locking mechanism. During use, as the reel rotates with the line, the three islands rotate as well, guiding the sliding post on the locking plate. The locking plate then slides left and right within the groove. Because there's a groove on each of the three islands that engages the sliding post, when the reel rotates counter-clockwise while the line is being pulled, the sliding post won't fall into the groove, thus preventing locking. When the reel rotates clockwise under the action of the internal spring, two scenarios occur: if the sliding post is in the outer channel, it also won't fall into the groove under the guidance of the three islands, meaning it won't lock. Alternatively, if the sliding post is in the inner channel, it will inevitably fall into the groove within one rotation under the guidance of the three islands, locking the line. At this point, the reeling action is interrupted, thus achieving the function of locking the line at a certain length. To restore the reel-in function, simply pull the line once to move the sliding post to the outer channel. To adjust the length of the locking line, pull it twice to achieve the desired length. This device provides a double locking mechanism, ensuring the rope remains fixed even in extreme conditions, greatly improving safety. It is highly practical and suitable for widespread adoption.

[0013] Meanwhile, the connecting mechanism ensures a secure connection between the rope and the equipment, effectively withstanding tension and impact, and increasing safety during use. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] During high-altitude operations, rope retrieval equipment is required. The rope retrieval equipment provided by this utility model is specifically designed for rope retrieval operations during high-altitude operations. When using this equipment for retrieval operations, it is essential to check whether the connecting mechanism 1 and the locking mechanism 2 are working properly before each use to ensure that the rope is securely connected and to avoid accidents caused by improper connection. Avoid exceeding the design load capacity to prevent equipment damage or danger. Keep the equipment clean to prevent dirt and foreign objects from accumulating on key components, which can affect the normal operation of the equipment. Regularly check for signs of wear, aging, or damage, and replace damaged parts in a timely manner if necessary.

[0020] like Figure 1 - Figure 3 As shown, this utility model provides a technical solution: a double-locking rope retractor, including a connecting mechanism 1 for connecting to a rope, a locking mechanism 2 for locking the rope on one side of the connecting mechanism 1, the locking mechanism 2 including a housing 201, at least three connecting blocks 202 on one inner wall of the housing 201, a rotating shaft 205 fixedly connected to one side of the housing 201, a winding reel 203 rotatably connected to the outer wall of the rotating shaft 205, a groove 204 on one inner wall of the housing 201, and a locking piece 209 slidably connected within the groove 204. 9 is rotatably connected to the rotating shaft 205. A locking assembly is provided inside the winding reel 203. The locking assembly includes three islands 206. The three islands 206 divide the inner wall of the winding reel 203 into an inner channel 208 and an outer channel 207. A sliding post 210 is fixedly connected to one side of the locking piece 209. The sliding post 210 slides along the three islands 206. A slot is opened on one side of the outer shell 201. An enlarged head 211 is slidably connected in the slot. A connecting rod 212 is fixedly connected to the outer wall of the enlarged head 211. A pull ring 213 is fixedly connected to one end of the connecting rod 212.

[0021] It is important to note that during use, when the reel 203 rotates under the influence of the line, the three islands 206 rotate accordingly, guiding the sliding post 210 on the locking plate 209. The locking plate 209 then slides left and right within the groove 204. Because there is a groove on each of the three islands 206 that allows the sliding post 210 on the locking plate 209 to engage, when the reel 203 rotates counterclockwise while the line is being pulled, the sliding post 210 will not fall into the groove, thus preventing locking. When the reel 203 rotates clockwise under the action of the internal spring to wind the line, there are two scenarios: when the sliding post 210 is in the outer channel 207, guided by the three islands 206, it will also not fall into the groove, meaning it will not lock. The other scenario is... When the sliding post 210 is in the inner channel 208, it will inevitably fall into the groove within one rotation under the guidance of the three islands 206, thus locking the line. At this point, the reeling action is interrupted, achieving the function of locking the line at a certain length. To restore the reeling function, simply pull the line, which will move the sliding post 210 to the outer channel 207. To adjust the length of the locked line, pull the line twice to achieve the desired length. Finally, manually control the pull ring 213 to control the expanded head 211 to slide within the outer shell 201 via the connecting rod 212 to adjust the angle. The locking mechanism 2 can easily adjust the state of the locking plate 209, achieving rapid adjustment of the rope tension to meet different work requirements.

[0022] like Figure 2 As shown, the connecting mechanism 1 includes a fixed ring 101, and a connecting ring 102 is rotatably connected to the inner wall of the fixed ring 101. A damping buckle 103 is installed on one side of the connecting ring 102.

[0023] It should be noted that during use, first connect the fixing ring 101, the outer shell 201, and the connector. Then, manually operate the damping buckle 103 to connect the connecting ring 102 and the connector. Finally, connect the connecting mechanism 1 and the connector. The connecting mechanism 1 ensures a firm connection between the rope and the equipment, effectively withstands tension and impact, and increases safety during use.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
