Description

Technical Field

[0001] This utility model relates to the field of rope fixing equipment technology, specifically to a rope fixing device. Background Technology

[0002] A rope fixer is a device used to secure ropes, ensuring their stability and safety during use. It has wide applications in various fields, including but not limited to: 1. Outdoor sports: such as mountaineering, rock climbing, and camping, used to secure tents, set up temporary facilities, and make lifelines; 2. Industrial production: such as hoisting heavy objects, securing equipment, and towing vehicles, ensuring safe and smooth operations; 3. Domestic life: such as securing luggage, fixing clothes racks, and pulling curtains, providing convenience and safety.

[0003] Most existing rope fixing devices have relatively complex structures. For example, Chinese invention patent CN119163727A, entitled "Rope Fixing Device," and Chinese invention patent CN106061313A, entitled "Rope Fastener," are not only complex, but also involve passing the rope through a through hole to fix it. This limits the diameter of the rope and even the length of the rope. If the fixing part is too short, it may affect the stability. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a rope fixing device. By setting a rotatable clamping member in the fixing frame, the clamping member presses the rope against the inner wall of the fixing frame, thereby fixing the rope tightly. The structure is simple, the operation is convenient, and there are few restrictions on the size of the rope.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rope fixing device, comprising a fixing frame, a rotating rod inserted into the fixing frame, and a clamping member fixedly connected to the rotating rod and located inside the fixing frame;

[0006] The fixing frame includes at least a first side plate opposite to the end of the clamping member, and a second side plate connected to the first side plate and perpendicular to each other.

[0007] Furthermore, the rotating rod is vertically inserted into the second side plate and rotatably connected to it; a spring is sleeved on the outside of the rotating rod, which causes the left end of the clamping member to tend to move closer to the first side plate during operation. One end of the spring is fixedly connected to the second side plate, and the other end of the spring is fixedly connected to the rotating rod or the clamping member.

[0008] Furthermore, when the clamping member moves from the first side of the reference plane that passes through the rotating rod and is perpendicular to the first side plate to the second side, or has a tendency to move from one side of the reference plane to the other side, the initial position of the clamping member is located on the first side of the reference plane.

[0009] Furthermore, when the second side plate is connected to the rear end of the first side plate, the fixing frame also includes a third side plate connected to the right end of the second side plate and opposite to the first side plate, and a fourth side plate connected to the front end of the third side plate and opposite to the second side plate; an opening is provided between the left end of the fourth side plate and the first side plate.

[0010] Furthermore, a gap is left between the rear end of the clamping member and the second side plate.

[0011] Furthermore, the clamping member includes at least a front end face and a rear end face; the right end of the front end face is connected to the rotating rod, and the left end is connected to the left end of the rear end face.

[0012] The beneficial effects of this utility model are as follows: by setting a rotatable clamping member inside the fixed frame, when the rope is placed between the clamping member and the inner wall of the fixed frame, the clamping member can reset and squeeze the rope under the action of the spring. The clamping member presses the rope against the inner wall of the fixed frame. Pulling the rope will increase the force of the pressure, thereby fixing the rope tightly. The structure is simple and easy to operate. Moreover, it has less restriction on the size of the rope. Ropes of different diameters can be put in. It is only necessary to pay attention to the size of the gap between the left end of the clamping member and the first side plate, or no gap can be left. Attached Figure Description

[0019] Example:

[0020] like Figures 1-3 As shown, a rope fixing device includes a rope 6, a fixing frame 1, a rotating rod 2 inserted into the fixing frame 1, and a clamping member 4 fixedly connected to the rotating rod 2 and located inside the fixing frame 1.

[0021] The fixed frame 1 includes at least a first side plate opposite to the end of the clamping member 4 for pressing the rope 6, and a second side plate connected to the first side plate and perpendicular to each other; during operation, the rope 6 is squeezed between the clamping member 4 and the first side plate.

[0022] like Figure 3 If the view shown is defined as a frontal view, then the first side panel is the panel on the left.

[0023] A portion of the rotating rod 2 is vertically inserted into the second side plate and rotatably connected to it. A spring 3 is sleeved on the outside of the rotating rod 2, which causes the left end of the clamping member 4 to tend to move closer to the first side plate during operation. One end of the spring 3 is fixedly connected to the second side plate, and the other end of the spring 3 is fixedly connected to the rotating rod 2 or the clamping member 4. The spring 3 resets the clamping member 4, causing it to move closer to the first side plate. During operation, if the second side plate is perpendicular to the bottom surface, the spring 3 needs to provide an initial force for the clamping member 4 to squeeze the rope. As the rope is stretched, it is squeezed closer, and the clamping member 4 experiences greater friction. Even without the spring 3, it will not fall off. When the second side plate is parallel to the ground, the spring can be omitted because there is no need for the initial tension of the rope to increase the friction of the clamping member 4 to counteract the weight of the clamping member 4 and squeeze the rope 6. In this state, the clamping member 4 can be pushed towards the first side plate by hand. Then, when the rope is stretched, the clamping member 4 will only experience a force in the same direction as the rope's movement, thus becoming increasingly tight.

[0024] When the clamping member 4 moves from the first side of the reference plane that passes through the rotating rod 2 and is perpendicular to the first side plate to the second side, or has a tendency to move from one side of the reference plane to the other, the initial position of the clamping member 4 is located on the first side of the reference plane, or in other words, the end of the clamping member 4 that abuts against the rope 6 is located on the first side; Figure 1As shown, the reference surface has two sides, namely the upper side and the lower side. When the clamping member 4 tends to move upward under the force of the rope 6, or when the rope 6 will be subjected to an upward tension, the initial position of the clamping member 4 is placed on the lower side of the reference surface, and the lower side is the first side. When the clamping member 4 tends to move downward under the force of the rope 6, or when the rope 6 will be subjected to a downward tension, the initial position of the clamping member 4 is placed on the upper side of the reference surface, and the upper side is the first side. When the rope 6 is inserted into the clamping member 4, the spring 3 causes the left end of the clamping member 4 to always tend to move closer to the reference surface.

[0025] When the second side plate is connected to the rear end of the first side plate, the fixing frame 1 also includes a third side plate connected to the right end of the second side plate and opposite to the first side plate, and a fourth side plate connected to the front end of the third side plate and opposite to the second side plate; an opening is provided between the left end of the fourth side plate and the surface where the first side plate is located; when the second side plate is located at the front end of the first side plate, there is no opening, and the third and fourth side plates can also be omitted, and the first side plate can be directly fixed to the mounting surface. At this time, the rear end face of the clamping member 4 and the rear end face of the first side plate have a gap smaller than the diameter of the rope 6.

[0026] A gap is left between the rear end of the clamping member 4 and the second side plate. The gap is smaller than the rope diameter. In particular, when the second side plate is parallel to the ground, it is more appropriate to make the gap smaller than the rope diameter to prevent the rope 6 from falling into the gap and not being pressed against the first side plate by the clamping member 4.

[0027] The clamping member 4 includes at least a front end face and a rear end face; the right end of the front end face is connected to the rotating rod 2, and the left end is connected to the left end of the rear end face. When the clamping member 4 includes three faces, the third face is the left end face of the clamping member 4. The two ends of the left end face are connected to the front end face and the rear end face respectively, and the left end face is arc-shaped and smoothly connected to the front end face and the rear end face respectively. The right end of the rear end face is connected to the rotating rod 2. The clamping member 4 can be hollow to reduce the weight and facilitate being reset by the spring 3; the rear end face is an upwardly convex arc shape.

[0028] During operation, rotating the rotating rod 2 increases the distance between the clamping member 4 and the first side plate, making the distance sufficient to insert the pull rope 6. The pull rope 6 can then be inserted from the... Figure 1 The rope 6 can be inserted from above or through opening 5. After the rope 6 is inserted, the rotating rod 2 is released. Under the action of the spring 3, the clamping member 4 presses the rope 6 tightly against the inner wall of the first side plate. The clamping member 4 is located below the horizontal line where the rotating rod 2 is located. Due to its size setting, when the rope 6 is subjected to an upward pulling force, the clamping member 4 will rotate upward. When the clamping member 4 rotates upward, it will press the rope 6 more tightly against the first side plate. At this time, the rope 6 is fixed.

[0029] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
