[0023] 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.

[0024] like Figures 1 to 4 As shown, one embodiment of this utility model is a quick-fastening device for water hoses at construction sites, comprising a solid round bar 1, a galvanized screw 2, an extended hexagonal nut 3, a wing screw 4, a semi-circular bar 5, a long plastic-coated steel wire rope 6, and a wire rope clip 7.

[0025] Solid round bar 1 serves as the top operating component, providing a gripping and force application point.

[0026] Galvanized screw 2, which is welded to solid round bar 1 to form a T-shaped screw.

[0027] The extended hexagonal nut 3 is rotatably connected to the bottom end of the galvanized screw 2. That is, the bottom part of the galvanized screw 2 is rotatably connected to the top part of the extended hexagonal nut 3. The extended design of the extended hexagonal nut 3 increases the contact area between the nut and the galvanized screw, making the connection more secure and able to withstand greater force. At the same time, when tightening the water hose, the extended hexagonal nut 3 can better distribute the force, reduce local stress concentration, improve the structural strength and stability of the entire device, and ensure that the semi-circular bar 5 can accurately act on the water hose to achieve effective tightening.

[0028] The wing screw 4 is threaded onto the surface of the galvanized screw 2 and engages with it. On construction sites, time is often very tight. This connection design of the galvanized screw 2, extended hexagonal nut 3, and wing screw 4 significantly shortens installation and adjustment time, improving work efficiency. By rotating the galvanized screw 2, the position of the wing screw 4 on the galvanized screw 2 can be flexibly adjusted to accommodate the fastening needs of water hoses of different diameters, enhancing the adaptability of the device.

[0029] The semi-circular bar 5 is symmetrically welded to both sides of the bottom of the extended hexagonal nut 3, and is used to contact the water hose to help tighten the water hose.

[0030] The long plastic-coated steel wire rope 6 and the wire rope clamp 7 are provided. Both ends of the long plastic-coated steel wire rope 6 are brazed to form hanging loops and are fixed by the wire rope clamp 7. The hanging loops at both ends of the long plastic-coated steel wire rope 6 are respectively fitted onto the top ends of the wing screw 4.

[0031] like Figures 1-4As shown, the solid round bar 1 has anti-slip knurling on its surface to increase friction during operation. As the top operating component, the solid round bar 1 provides the operator with a gripping and force application point. The anti-slip knurling significantly increases the friction between the operator's hand and the bar. On the construction site, operators' hands may be wet, oily, or muddy; the anti-slip knurling effectively prevents slippage, allowing the operator to rotate the T-screw more stably and effectively to tighten the hose, improving accuracy and efficiency while ensuring operator safety. The galvanized screw 2 has a trapezoidal thread to enhance its strength and wear resistance. The outer side of the semi-circular rod 5 is wrapped with an elastic rubber sleeve. The surface of the rubber sleeve has concave and convex textures to increase the friction with the hose. The semi-circular rod 5 directly contacts the hose, assisting in the fastening of the hose. The elastic rubber sleeve of the semi-circular rod 5 can fit tightly against the surface of the hose during the fastening process, playing a role in buffering and protecting the hose, preventing the hose from breaking due to excessive compression. At the same time, the concave and convex textures increase the friction with the hose, allowing the semi-circular rod to clamp the hose more firmly, preventing the hose from sliding or falling off under fluid pressure or external force, thus improving the stability and sealing of the hose connection. The outer plastic layer of the long-strapped plastic-coated steel wire rope 6 is flexible and corrosion-resistant, while the internal steel wire provides sufficient strength. On construction sites, water hoses may be affected by various complex environmental factors, such as moisture and corrosive substances. The corrosion resistance of the outer plastic layer ensures that the wire rope can be used for a long time in these harsh environments without damage. The flexibility allows the wire rope to adapt to water hoses and joints of different shapes and sizes, better restraining the water hose. The internal steel wire ensures that the wire rope has sufficient strength to withstand the tension generated by the water hose during use, ensuring the reliability of the water hose connection. The wire rope clamp 7 includes a U-shaped rod 71, a clamp block 72 movably sleeved on the surface of the U-shaped rod 71, and a clamp groove 73 formed on the inner side of the clamp block 72. Fastening screws 74 are threaded to both ends of the U-shaped rod 71. The U-shaped rod 71 is made of high-strength alloy steel, ensuring the overall strength of the clamp and enabling it to withstand greater tensile force. The clamp block 72 fits tightly with the U-shaped rod 71. The shape of the clamp groove 73 is adapted to the long plastic-coated steel wire rope 6. By tightening the fastening screws 74, the long plastic-coated steel wire rope 6 can be firmly fixed in the clamp groove 73, preventing the wire rope from slipping. This structural design allows the wire rope clamp 7 to reliably connect and fix the long plastic-coated steel wire rope 6, ensuring the stability and safety of the entire fastening device and providing strong protection for the fastening of the hose.

[0032] The working principle of the quick-fastening device for water hoses at the construction site described in this embodiment is as follows: Two semi-circular rods 5 are placed against the connection between the hose and the connector. The end of the long plastic-coated steel wire rope 6 is fixed with a wire rope clamp 7 to form a hanging loop. Specifically, the long plastic-coated steel wire rope 6 is placed into the groove 73 inside the clamp block 72. Then, the clamp block 72 is put onto the U-shaped rod 71. The U-shaped rod 71 is made of high-strength alloy steel to ensure strength. Finally, the fastening screws 74 at both ends of the U-shaped rod 71 are tightened so that the clamp block 72 and the U-shaped rod 71 fit tightly together, and the end of the bent long plastic-coated steel wire rope 6 is firmly fixed in the groove 73 to form a hanging loop. After wrapping the long plastic-coated steel wire rope 6 around the connection point between the hose and the joint at least once, place the hanging loops at both ends of the long plastic-coated steel wire rope 6 onto the tops of the wing screws 4. Depending on the actual diameter of the hose and the tightening requirements, the operator can directly rotate the solid round bar 1 by hand. The solid round bar 1 drives the galvanized screw 2 to rotate. Since the wing screw 4 is threaded onto the surface of the galvanized screw 2, the position of the wing screw 4 on the galvanized screw 2 can be adjusted by rotation, thereby tightening the long plastic-coated steel wire rope 6 and the hose.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
