[0024] 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.
[0025] Please see Figure 1 - Figure 5 The present invention provides a technical solution: a fall protection kit, including a safety rope body 1, wherein the safety rope body 1 includes a safety section 102 and a telescopic section 101;
[0026] A tensioner 2 is provided between the safety section 102 and the telescopic section 101. Several movable rings 216 are slidably mounted on the outside of the telescopic section 101. The tensioner 2 includes a pair of mounting plates 201. A connecting plate 202 is fixedly connected to the side of the mounting plate 201. A lifting ring 203 is fixedly connected to the side of the connecting plate 202. A fixing post 204 is fixedly connected to the inside of the mounting plate 201. A rotating shaft 205 is rotatably connected to the inside of the connecting plate 202. A connecting shaft 206 is rotatably mounted on the outside of the connecting plate 202. One end of the shaft 206 is fixedly connected to the rotating shaft 205, and the other end of the connecting shaft 206 is fixedly connected to the ratchet 207. The outer side of the connecting plate 202 is provided with a hook 210 and a one-way stop 212. One end of the hook 210 engages with the ratchet 207, and the other side of the hook 210 is fixedly connected to the rotating shaft 211. The rotating shaft 211 is rotatably connected to the connecting plate 202. A torsion spring 213 is sleeved on the outside of the rotating shaft 211. One end of the torsion spring 213 is fixed to the connecting plate 202, and the other end is fixedly connected to the rotating shaft 211.
[0027] The hook 210 has a threaded connection to a pin 214 at its center, and the connecting plate 202 has two positioning holes 215 on its exterior, with the pin 214 inserted into the positioning holes 215. One end of the safety section 102 is fixedly connected to the fixed post 204, and one end of the telescopic section 101 passes through and is fixedly connected to the rotating shaft 205. An external disc 208 is fixedly connected to the exterior of a ratchet 207, and a crank 209 is rotatably connected to the outer edge of the external disc 208. The end of the safety section 102 away from the tensioner 2 is connected to a second buffer pack 105 and fixedly connected to a second safety buckle 106, while the end of the telescopic section 101 away from the tensioner 2 is connected to a first buffer pack 103 and fixedly connected to a first safety buckle 104. The telescopic section 101 has at least one movable ring 216, which can effectively guide… The movable ring 216 guides the movement direction of the safety rope 1, preventing it from tangling or knotting during use. Simultaneously, it reduces direct friction between the safety rope 1 and other objects, minimizing wear and extending its service life. Furthermore, the movable ring 216 facilitates quick adjustments to the position and direction of the safety rope 1 by the operator, improving operational convenience. The two buffer packs can be connected in two different ways: one is that the second buffer pack 105 directly forms part of the safety section 102, is fixed to the safety section 102, and is located near the second safety buckle 106; the other is that the first safety buckle 104 is directly and fixedly connected to the first buffer pack 103. When performing high-altitude operations on a large rooftop platform, operators often need to move left and right within the platform's width. In the traditional way, if the operator's safety rope is fixed at a single point, the range of motion will be severely restricted. This device can fix the safety rope between two posts or other fixed objects through the fixed rope 3 to form a horizontal safety rope. After the operator connects his own safety rope to this horizontal safety rope through the movable ring 216, the range of motion can cover the entire width between the two fixed points, thereby significantly improving the work efficiency.
[0028] Both the first safety buckle 104 and the second safety buckle 106 are equipped with fixing ropes 3 on their exterior. A metal ring 301, compatible with the first safety buckle 104, is fixedly connected to the middle of the outer side of each fixing rope 3. The fixing rope 3 is tied to the exterior of the building. The metal ring 301 is made of steel. The metal rings 301 at both ends of the fixing rope 3, together with the safety buckles at the ends of the safety rope body 1 (i.e., the first safety buckle 104 and the second safety buckle 106), form a reliable connection structure. This ensures both connection strength and ease of quick installation and disassembly. Furthermore, the flexibility in knotting and binding the fixing rope 3 provides greater adaptability, allowing the actual length of the fixing rope 3 used to be controlled according to the specific conditions of different building structures, thus enhancing the system's versatility.
[0029] The safety section 102 is externally equipped with a tool bag 4, which includes two interconnected semi-enclosed bags 401. A connecting rope 402 is fixedly connected to the outside of one semi-enclosed bag 401, and the other end of the connecting rope 402 is fixedly connected to the safety section 102. A handle 403 is fixedly connected to the outside of the semi-enclosed bag 401. The edges of the two semi-enclosed bags 401 are connected or separated by a zipper. A wrapping strap 404 is fixedly connected to the outside of one handle 403. Attachments 405 are fixedly installed on the inside of the wrapping strap 404 and the outside of the other handle 403. This design gives the tool bag 4 a dual function: in the non-use state, the tool bag 4 can completely store all components of the safety rope system, making it easy to carry and transport; in the use state, the tool bag 4 can be transformed into a hanging tool storage device through the flip design after the zipper is fully opened. In particular, the combination design of handle 403, wrapping tape 404 and mating tape 405 not only facilitates the carrying of tool bag 4, but more importantly, it can reliably bind the two handles 403 together when working at height, preventing the tool bag 4 from accidentally falling off during high-altitude operations, thus improving work safety. The mating tape 405 is fixed to the wrapping tape 404, and the mating tape 405 is fixed to the outside of handle 403.
[0030] The two positioning holes 215 are distributed in a circle, with the center of the circle being the pivot 211; the screw pin 214 is inserted into different positioning holes 215, corresponding to the free rotation and locked states of the ratchet 207 respectively.
[0031] Working principle: Before using this fall protection kit, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 5 As shown, by having two fixed ropes 3 horizontally tied to the outside of the building, the first safety buckle 104 and the second safety buckle 106 are respectively fastened to different metal rings 301;
[0032] By rotating the hook 210 and inserting the screw 214 into the positioning hole 215 away from the ratchet 207, during the process of pulling the telescopic section 101, the rotating shaft 205 will drive the ratchet 207 to rotate freely. After the two safety buckles are installed, by rotating the screw 214, the insertion of the screw into the positioning hole 215 is released, so that the hook 210 is reset under the action of the torsion spring 213 and engages with the ratchet 207. At this time, the length of the telescopic section 101 is locked and cannot be extended.
[0033] Then, by shaking the handle 209, the outer disc 208 is rotated, which in turn drives the connecting shaft 206 to rotate through the ratchet 207, thereby causing the rotating shaft 205 to rotate and wrap around the telescopic section 101 to tighten it, ultimately keeping the safety rope 1 taut.
[0034] Finally, the worker's safety buckle is engaged with the movable ring 216, allowing the worker to move freely in the horizontal direction along with the movable ring 216.
[0035] When not in use, the tensioner 2 and the fixing rope 3 are placed inside the two semi-enclosed bags 401. Then, the two semi-enclosed bags 401 are connected together by a zipper. Finally, the two tabs 405 are glued together with the wrapping tape 404, making all parts easy to carry.
[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
