Description

Technical Field

[0001] This utility model relates to the field of detonating cord take-up roller technology, specifically a detonating cord take-up roller with an anti-loosening structure. Background Technology

[0002] In blasting operations, detonating cord is typically used to transfer explosive energy to detonate other explosives or explosive devices. For ease of carrying, storage, and use, detonating cord is usually wound onto a take-up roller. The main function of the detonating cord take-up roller is to wind up and store the detonating cord. The detonating cord take-up roller may also have the function of protecting the detonating cord from damage, such as preventing it from getting wet, contaminated, or subjected to physical damage, thereby ensuring that the detonating cord can be detonated normally when needed.

[0003] However, most detonating cord take-up rollers are not restricted when they are ready for use, which makes it easy for the detonating cord to become loose. As a result, the loose detonating cord is prone to knotting when it is ready for use, which makes it time-consuming to unlock the detonating cord later. This makes it inconvenient to transport the detonating cord. Utility Model Content

[0004] The purpose of this invention is to provide a detonating cord take-up roller with an anti-loosening structure to solve the problem of detonating cord take-up rollers easily becoming loose during use, as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detonating cord take-up roller with an anti-loosening structure, comprising a take-up frame, a take-up roller body, and a detonating cord body. The take-up roller body is located at one end of the take-up frame, and the detonating cord body is connected to the surface of the take-up roller body. A protective frame is located on one side of the take-up frame, and a first gear connected to the take-up roller body is located inside the protective frame. A limiting gear ring is meshed at one end of the first gear, and the limiting gear ring is T-shaped. A limiting spring connects the limiting gear ring to the protective frame.

[0006] Preferably, a limiting block is provided at the end of the limiting gear ring away from the first gear, and a rotating plate is connected to one side of the limiting block.

[0007] Preferably, a torsion spring is connected between the rotating plate and the protective frame, and a limiting rod is connected between one end of the rotating plate and the protective frame.

[0008] Preferably, a fixed frame is provided at one end of the take-up frame near the take-up roller body, a rotating handwheel is provided at one end of the fixed frame, and a rotating rod is connected to one end of the rotating handwheel.

[0009] Preferably, a second gear is provided at the end of the rotating rod away from the rotating handwheel, and both ends of the second gear are meshed with racks.

[0010] Preferably, one end of each rack is connected to a connecting rod, and the end of the connecting rod away from the rack is connected to a connecting plate.

[0011] Preferably, a protective plate is connected to one side of the connecting plate, and a cutting blade is connected to one side of the other connecting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This detonating cord take-up roller with an anti-loosening structure, by loosening the rotating plate, allows the limiting block to push the limiting gear ring, which in turn limits the first gear, thereby limiting the take-up roller body. This prevents the detonating cord body from becoming loose after the take-up roller body rotates. By rotating the rotating handwheel, the connected rotating rod can move the rack through the second gear, so that the rack can move the connected connecting plate when it moves, and at the same time drive the protective plate and the cutting blade to move, thereby enabling rapid cutting of the detonating cord and facilitating its use.

[0013] 1. This detonating cord take-up roller with an anti-loosening structure is designed to prevent loosening during use. Loosening the rotating plate allows the torsion spring connected to it to release its restraint, causing it to reset. This allows the rotating plate to push the limiting gear ring via the limiting block. The limiting gear ring, in turn, stretches the connecting limiting spring and restricts the first gear, preventing it from slipping. This prevents the take-up roller body from loosening, thus limiting the detonating cord wound on its surface and preventing loosening before use. This results in a better anti-loosening effect for the detonating cord take-up roller during use.

[0014] 2. This detonating cord take-up roller with an anti-loosening structure addresses the common inconvenience of cutting detonating cord during use. This is achieved by passing the detonating cord through the fixed frame and rotating the handwheel. The handwheel then moves the rack via the second gear, which in turn moves the connecting plate via the connecting rod. Since the racks are on either side of the second gear, they move the two connecting plates respectively. This movement of the connecting plates then moves the protective plate and the cutting blade, allowing for the cutting of the detonating cord. This improved cutting efficiency and prevents the inconvenience caused by difficulty in cutting the cord. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1-3This utility model provides a technical solution: a detonating cord take-up roller with an anti-loosening structure, including a take-up frame 1, a take-up roller body 2, and a detonating cord body 3. The take-up roller body 2 is provided at one end of the take-up frame 1, and the detonating cord body 3 is connected to the surface of the take-up roller body 2. A protective frame 4 is provided on one side of the take-up frame 1. A first gear 5 connected to the take-up roller body 2 is provided inside the protective frame 4. A limiting gear ring 6 is meshed at one end of the first gear 5. The limiting gear ring 6 is T-shaped. A limiting spring 7 is connected between the limiting gear ring 6 and the protective frame 4. A limiting block 8 is provided at the end of the limiting gear ring 6 away from the first gear 5. A rotating plate 9 is connected to one side of the limiting block 8. A torsion spring 10 is connected between the rotating plate 9 and the protective frame 4. A limiting rod 11 is connected between one end of the rotating plate 9 and the protective frame 4.

[0024] In practice,

[0025] See Figures 1-3 It is known that the detonating cord take-up roller is prone to loosening during use. This can be addressed by loosening the rotating plate 9, which allows the torsion spring 10 connected to the rotating plate 9 to lose its restraint. Consequently, the torsion spring 10 can reset, causing the rotating plate 9 to rotate and rotate the connected limiting block 8. As the limiting block 8 rotates, it pushes the limiting gear ring 6 at one end, which in turn stretches the connected limiting spring 7. Simultaneously, the limiting gear ring 6 restricts the first gear 5 during its movement, preventing it from slipping. This prevents the take-up roller body 2 from loosening, thus limiting the detonating cord body 3 wrapped on its surface and preventing it from loosening when ready for use. This gives the detonating cord take-up roller a better anti-loosening effect during use.

[0026] A fixed frame 12 is provided at one end of the take-up frame 1 near the take-up roller body 2. A rotating handwheel 13 is provided at one end of the fixed frame 12. A rotating rod 14 is connected to one end of the rotating handwheel 13. A second gear 15 is provided at the end of the rotating rod 14 away from the rotating handwheel 13. Both ends of the second gear 15 are meshed with racks 16. A connecting rod 17 is connected to one end of each rack 16. A connecting plate 18 is connected to the end of the connecting rod 17 away from the rack 16. A protective plate 19 is connected to one side of the connecting plate 18, and a cutting blade 20 is connected to the other side of the connecting plate 18.

[0027] In practice,

[0028] See Figure 1 , Figure 4 , Figure 5 and Figure 6It is known that detonating cord take-up rollers are generally not easy to cut detonating cord during use, which makes the detonating cord inconvenient to use. This can be addressed by passing the detonating cord body 3 through the fixed frame 12 and then rotating the handwheel 13. When the handwheel 13 rotates, it rotates the connected second gear 15. When the second gear 15 rotates, it moves the racks 16 meshing on both sides. When the racks 16 rotate, they move the connected connecting rod 17. At the same time, when the connecting rod 17 moves, it moves the connecting plate 18 connected at the bottom. Since the racks 16 are on both sides of the second gear 15, when the two racks 16 move, they can move the two connected connecting plates 18 respectively. When the connecting plates 18 move, they can drive the protective plate 19 and the cutting blade 20 to move. After moving, they can cut the detonating cord body 3, so that the detonating cord take-up roller can cut the detonating cord better during use, avoiding the inconvenience caused by the difficulty in cutting.

[0029] In summary, in blasting operations, detonating cord is typically used to transfer explosive energy to detonate other explosives or explosive devices. For ease of carrying, storage, and use, the detonating cord is usually wound around a take-up roller. By loosening the rotating plate 9, the limiting block 8 can push the limiting gear ring 6, which in turn limits the first gear 5, thereby limiting the take-up roller body 2. This prevents the detonating cord body 3 from loosening after the take-up roller body 2 rotates. The contents not described in detail in this specification are prior art known to those skilled in the art.

[0030] 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.
