Description

Technical Field

[0001] This utility model relates to the technical field of hose fixing devices, specifically a buckle-type RV sewage hose fixing strap. Background Technology

[0002] In the area of ​​wastewater discharge from RVs and other recreational vehicles, a pipe elbow is typically used to connect the drain hose to a vertical ground drain riser. To ensure a secure connection during discharge and to prevent the elbow from detaching due to wastewater flow or accidental impact, a specialized securing device is required.

[0003] Several fixing belt assemblies for this purpose currently exist on the market. For example, US Patent 11022246B1 discloses a fixing belt assembly comprising a horizontal belt wound around a riser and a rotating belt pivotally connected to the horizontal belt and clamping the elbow. This assembly tightens the horizontal belt and the rotating belt separately via two independent ratchet mechanisms. However, this prior art has significant drawbacks: 1. The tightening of both the horizontal and rotating belts relies on a ratchet mechanism, whose gears need to mesh with pre-cut toothed holes on the belt body. This hollowed-out structure significantly weakens the mechanical strength of the belt body itself. Especially under long-term use or when subjected to high stress, the hollowed-out parts are prone to tearing or breaking, leading to the failure of the entire fixing device.

[0004] 2. Because its horizontal belt and ratchet mechanism form a closed loop, the entire assembly must be inserted from the top of the riser during installation. This makes it impossible to install the assembly on some risers with fixed flanges or obstacles at the top (such as some green drain outlets), thus limiting its application scenarios. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a snap-on RV sewage hose fixing strap. Through two independent snap-on structures—a first snap-on tightening component and a second snap-on tightening component—this design is openable and closable, and the entire strap body has no hollowed-out structure, achieving both installation flexibility and overall high durability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a buckle-type RV sewage hose fixing strap for fixing the sewage hose to a sewage riser, comprising a horizontal main strap, a first buckle-type tightening assembly, and a second buckle-type tightening assembly; the two ends of the first buckle-type tightening assembly are respectively connected to the two ends of the horizontal main strap, forming a horizontal circumference that surrounds the outer wall of the sewage riser and is infinitely adjustable; the two ends of the second buckle-type tightening assembly are rotatably connected to the circumference, and can rotate upward to vertically surround the outer wall of the sewage hose, and can be infinitely adjusted to lock the sewage hose.

[0007] Furthermore, the first buckle-type tightening assembly includes a first buckle and a first buckle. The first buckle is fixedly installed at one end of the horizontal main strap, the first end of the first buckle is rotatably connected to the other end of the horizontal main strap, and the second end of the first buckle is snapped together with the first buckle.

[0008] Furthermore, the outer surface of the first card is provided with a plurality of first card slots arranged side by side along the length direction. The first latch includes a first base plate and a first rotating block. The first rotating block is rotatably connected to the first base plate for engaging any one of the first card slots to achieve stepless adjustment around the circumference.

[0009] Furthermore, the first latch also includes a first cover plate, which is rotatably connected to the first base plate via a pivot.

[0010] Furthermore, the first base plate extends upward on both sides along its length to form a plurality of first bending limiting blocks, and a first accommodating space for accommodating the first cartridge is formed between the first bending limiting blocks and the first base plate.

[0011] Furthermore, the second buckle-type tightening assembly includes a second buckle and a second buckle, with the second buckle being snapped together with the second buckle.

[0012] Furthermore, the outer surface of the second card is provided with a plurality of second card slots arranged side by side along the length direction. The second buckle includes a second base plate and a second rotating block. The second rotating block is rotatably connected to the second base plate for engaging any one of the second card slots to achieve stepless adjustment around the circumference.

[0013] Furthermore, the two ends of the second buckle-type tightening component are rotatably connected in the circumferential direction by a first turning belt and a second turning belt respectively; one end of the first turning belt is rotatably connected to the circumferential direction and the other end is rotatably connected to the second buckle; one end of the second turning belt is rotatably connected to the circumferential direction and the other end is fixedly connected to the second lock.

[0014] Furthermore, the second latch also includes a second cover plate, which is rotatably connected to the second base plate via a pivot.

[0015] Furthermore, the second base plate extends upward along both sides in the length direction to form a plurality of second bending limiting blocks, and a second accommodating space for accommodating the second card is formed between the second bending limiting blocks and the second base plate.

[0016] This utility model's snap-on RV sewage hose fixing strap, through the adoption of a novel "snap-on buckle" tightening solution, has the following beneficial technical effects: 1. It completely abandons the weak structure of cutting out teeth in the belt body in the existing technology, and adopts a complete, non-cut-out belt and buckle cooperation. This makes the belt body uniformly stressed, with high mechanical strength, avoiding the risk of tearing or breaking due to stress concentration, greatly extending the product life and significantly improving durability.

[0017] 2. Since the horizontal main strap is not a closed loop, but is opened and closed through the first buckle fastening component, the fixing strap can be easily put on the sewage riser from the side without having to be inserted from the top of the riser, achieving truly quick installation. This perfectly solves the problem of dealing with complex installation scenarios such as flanges, obstacles or narrow spaces at the top, and has a wide range of applications.

[0018] 3. The buckle-type adjustment method is similar to a common belt buckle. Users can perform stepless adjustment and quick locking / unlocking without tools. The operation experience is simpler and faster than that of a ratchet mechanism. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Please see the appendix Figure 1-4 As shown, this utility model provides a snap-on type RV sewage hose fixing strap 100 for fixing a sewage hose 200 to a sewage riser 300. It includes a horizontal main strap 11, a first snap-on tightening assembly 12, and a second snap-on tightening assembly 2. The horizontal main strap 11 serves as a basic frame, supporting and wrapping the sewage riser 300. The two ends of the first snap-on tightening assembly 12 are connected to the two ends of the horizontal main strap 11, forming a horizontally encircling circumference 1 around the outer wall of the sewage riser 300, which is infinitely adjustable. The first snap-on tightening assembly 12 and the horizontal main strap 11 form an openable and closable structure, and its infinitely adjustable capability ensures that the fixing strap 100 can tightly adapt to sewage risers 300 of different diameters. Both ends of the second snap-on tightening assembly 2 are rotatably connected to the circumference 1, allowing it to rotate upwards to vertically encircle the outer wall of the sewage hose 200, and is infinitely adjustable to lock the sewage hose 200. The second snap-on tightening assembly 2 is rotatably connected at both ends to the circumference 1, allowing it to flip upwards and change from a horizontal to a vertical orientation to wrap around and compress the sewage hose 200. Its stepless adjustment capability ensures effective compression of sewage hoses 200 of different diameters. Through these two independent snap-on structures—the first snap-on tightening assembly 12 and the second snap-on tightening assembly 2—this design is openable and closable, with no hollowed-out structure throughout the entire belt, achieving installation flexibility and high overall durability.

[0026] The first buckle-type tightening assembly 12 includes a first buckle 121 and a first buckle 122. The first buckle 121 is fixedly installed at one end of the horizontal main strap 11. The first end of the first buckle 122 is rotatably connected to the other end of the horizontal main strap 11, and the second end of the first buckle 122 is snapped into place with the first buckle 121. The first buckle 121 is fixed, and the first buckle 122 is rotatably connected, forming a one-sided movable fastening method. This fastening method has a clear, reliable, and easy-to-implement stepless adjustable locking mechanism around a circumference of 1.

[0027] As attached Figure 3 As shown, the outer surface of the first card slot 122 is provided with a plurality of first card slots 1221 arranged side by side along the length direction, as shown in the attached figure. Figure 4As shown, the first latch 121 includes a first base plate 1211 and a first rotating block 1212. The first rotating block 1212 is rotatably connected to the first base plate 1211 and is used to engage with any one of the first slots 1221 to achieve stepless adjustment around the circumference 1. The first slot 1221 is recessed on the complete surface of the first strap 122, which does not disrupt the continuity of the strap and provides multiple discrete latching points. The first rotating block 1212 acts as a locking mechanism, engaging with the first slot 1221 to achieve locking. Preferably, the multiple first slots 1221 are equidistantly spaced, achieving reliable unidirectional locking and precise stepless adjustment. Users can precisely control the tightness by selecting different positions of the first slots 1221, and the latch is not easy to loosen after locking, with good load-bearing performance.

[0028] The first latch 121 further includes a first cover plate 1213, which is rotatably connected to the first base plate 1211 via a pivot. The first cover plate 1213 is used to press the first rotating block 1212 to prevent it from accidentally disengaging. The first cover plate 1213 can also be used to press the first retaining band 122. When the first cover plate 1213 is closed, it prevents the first retaining band 122 from accidentally disengaging from the first rotating block 1212, thus improving the safety and reliability of the product.

[0029] The first base plate 1211 extends upward along both sides in the length direction to form a plurality of first bending limiting blocks 1214. The first bending limiting blocks 1214 and the first base plate 1211 form a first receiving space for accommodating the first cartridge 122. The first receiving space serves as a track for guiding and restricting the movement of the first cartridge 122, ensuring that the first cartridge 122 can only slide along the length direction within the first latch 121, preventing it from shifting laterally, twisting, or coming off, making the adjustment process smoother and the locking state more stable.

[0030] As attached Figure 1As shown, the second buckle-type tightening assembly 2 includes a second latch 21 and a second buckle 22, with the second buckle 22 snapped together with the second latch 21. The force-bearing foundation of the second buckle-type tightening assembly 2 is established on the already locked circumference 1, ensuring that the drain hose 200 can be pressed down and tightened. The outer surface of the second buckle 22 has multiple second slots recessed side-by-side along its length. The second latch 21 includes a second base plate and a second rotating block, which is rotatably connected to the second base plate for engaging any of the second slots to achieve stepless adjustment of the circumference 1. The second latch 21 also includes a second cover plate, which is rotatably connected to the second base plate via a pivot. The second base plate extends upwards on both sides along its length to form multiple second bending limiting blocks, creating a second accommodating space between the second bending limiting blocks and the second base plate to accommodate the second buckle 22. The structure of the second latch 21 and the second buckle 22 is the same as that of the first latch 121 and the first buckle 122, and their operating principles are the same.

[0031] The two ends of the second buckle-type tightening assembly 2 are rotatably connected in the circumferential direction of the circumference 1 via a first bending band 23 and a second bending band 24, respectively. One end of the first bending band 23 is rotatably connected to the circumferential direction of the circumference 1, and the other end is rotatably connected to the second buckle 22. One end of the second bending band 24 is rotatably connected to the circumferential direction of the circumference 1, and the other end is fixedly connected to the second locking buckle 21. The first bending band 23 and the second bending band 24 serve as connectors between the circumferential direction of the circumference 1 and the second buckle-type tightening assembly 2, achieving a rotatable connection. Because the first bending band 23 and the second bending band 24 are rotatably connected in the circumferential direction of the circumferential direction of the circumference 1, the second buckle 22 can be moved away from the central axis of the sewage riser 300, causing the tightening point to move away from the bend of the sewage hose 200, thereby providing a better lever arm and pressing the sewage hose 200 more stably onto the sewage riser 300, preventing it from coming off.

[0032] The snap-on type RV sewage hose fixing strap 100 of this utility model, by adopting the novel tightening solution of "snap-on buckle", has the following beneficial technical effects: 1. It completely abandons the weak structure of cutting out teeth in the belt body in the existing technology, and adopts a complete, non-cut-out belt and buckle cooperation. This makes the belt body uniformly stressed, with high mechanical strength, avoiding the risk of tearing or breaking due to stress concentration, greatly extending the product life and significantly improving durability.

[0033] 2. Since the horizontal main strap 11 is not a closed loop, but is opened and closed through the first buckle fastening component 12, the fixing strap 100 can be easily put on the sewage riser 300 from the side without having to be inserted from the top of the sewage riser 300, thus achieving truly quick installation. This perfectly solves the problem of dealing with complex installation scenarios such as flanges, obstacles or narrow spaces at the top, and has a wide range of applications.

[0034] 3. The buckle-type adjustment method is similar to a common belt buckle. Users can perform stepless adjustment and quick locking / unlocking without tools. The operation experience is simpler and faster than that of a ratchet mechanism.

[0035] 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 claims and their equivalents.
