Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, specifically to an outdoor fire hydrant hose connector with multi-size locking function. Background Technology

[0002] Firefighting is an abbreviation for eliminating hidden dangers, preventing and extinguishing fires. In essence, it is a systematic work centered around fire prevention and control, covering prevention before a fire occurs, firefighting during a fire, and recovery and summary after a fire. The ultimate goal is to protect people's lives and safety, reduce property losses, and maintain public order and ecological environment stability. During the firefighting process, a lot of firefighting equipment is used, such as fire hydrants, fire pipes and fire pipe joints.

[0003] Currently, most outdoor fire hydrant hose connectors on the market are designed with fixed sizes, meaning that one type of connector can only match one type of fire hose with a specific inner diameter. However, in actual fire rescue scenarios, due to differences in fire type, fire size, and rescue environment, firefighters often need to carry multiple fire hoses of different sizes. When it is necessary to change to a different size hose, the corresponding connector must be replaced. This process not only wastes valuable rescue time but may also delay the best time to extinguish the fire due to incomplete connectors and cumbersome replacement operations. Utility Model Content

[0004] The purpose of this utility model is to provide an outdoor fire hydrant hose connector with multiple sizes and locking functions to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an outdoor fire hydrant hose connector with multi-size locking function, comprising a first hose and a second hose, wherein a connecting pipe is installed inside the first hose and the second hose, a main locking mechanism is installed on the outer surface of the first hose and the outer surface of the second hose, and a secondary locking mechanism is installed on the outer surface of both the first hose and the second hose.

[0006] Preferably, the main locking mechanism includes an upper locking shell, and two fixing blocks are fixedly connected to the outer surface of the upper locking shell.

[0007] Preferably, each of the fixing blocks has a threaded hole on its outer surface, and a threaded rod is threaded into the interior of each threaded hole.

[0008] Preferably, the outer surfaces of the two threaded rods are connected by a common thread to a lower locking shell, and the inner walls of the lower locking shell and the upper locking shell are both fixedly fitted with rubber anti-slip pads.

[0009] Preferably, the secondary locking mechanism includes a flexible locking ring, and the outer surface of the flexible locking ring has a plurality of locking holes.

[0010] Preferably, the outer surface of the flexible locking ring is threaded with a locking rod, and the outer surface of the locking rod is adapted to the interior of the locking hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a connecting pipe as a universal adapter, simultaneously accommodating both a first and second flexible hose. Combined with the adjustable locking range of the main locking mechanism and the flexible locking ring of the secondary locking mechanism to adapt to different pipe diameters, it is compatible with fire hoses of various inner diameters. This eliminates the need for separate connectors for different hose sizes, significantly reducing the amount of equipment firefighters carry and lowering equipment management costs. The included rubber anti-slip pad increases friction with the hose's outer surface, preventing slippage, and the elastic deformation of the rubber fills the gap between the hose and the connecting shell, improving sealing. This solves the problem of fixed-size designs, where one connector can only match one specific inner diameter fire hose. This often forces firefighters to carry multiple hoses of different sizes, requiring them to replace the corresponding connector when changing hoses, wasting valuable rescue time and potentially delaying optimal firefighting opportunities due to incomplete connectors and cumbersome replacement procedures.

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0015] Please see Figure 1-4As shown, an outdoor fire hydrant hose connector with multi-size locking function includes a first hose 1 and a second hose 2. A connecting pipe 3 is installed inside the first hose 1 and the second hose 2. A main locking mechanism 4 is installed on the outer surface of the first hose 1 and the outer surface of the second hose 2. A secondary locking mechanism 5 is installed on the outer surface of both the first hose 1 and the second hose 2. The inner diameter of the connecting pipe 3 is designed to be compatible with various hose inner diameters, and can simultaneously accommodate first hoses and second hoses 2 of different sizes, providing a unified connection carrier for multi-size hoses and solving the problem of single-size adaptation in traditional connectors.

[0016] The main locking mechanism 4 includes an upper locking shell 41. Two fixing blocks 42 are fixedly connected to the outer surface of the upper locking shell 41. Each fixing block 42 has a threaded hole 43 on its outer surface. A threaded rod 44 is threadedly connected inside each threaded hole 43. The outer surfaces of the two threaded rods 44 are threadedly connected to a lower locking shell 45. Rubber anti-slip pads 46 are fixedly installed on the inner wall of the lower locking shell 45 and the inner wall of the upper locking shell 41. After the upper locking shell 41 and the lower locking shell 45 are engaged, they can completely cover the connection between the hose and the connecting pipe 3, forming a circumferential constraint on the hose from the outside, restricting the radial displacement and axial sliding of the hose. When the threaded rod 44 rotates, it drives the upper locking shell 41 and the lower locking shell 45 to move closer together through the threaded engagement, forming a circumferential pressure on the hose.

[0017] The secondary locking mechanism 5 includes a flexible locking ring 51. The outer surface of the flexible locking ring 51 has several locking holes 52. A locking rod 53 is threadedly connected to the outer surface of the flexible locking ring 51. The outer surface of the locking rod 53 is adapted to the inside of the locking holes 52. The flexible locking ring 51 can adaptively shrink according to the outer diameter of the hose, closely fit the outer surface of the hose, and form a local clamping force to supplement the fixing effect of the main locking mechanism 4. After the locking rod 53 is inserted into the locking hole 52, it can lock the shrinkage state of the flexible locking ring 51 to prevent it from loosening due to elastic rebound and ensure that the local clamping force continues to act.

[0018] Working principle: First, the connecting tube 3 is placed between the first hose 1 and the second hose 2. The connecting tube 3, as the core adapter component, is designed with an inner diameter compatible with various hose inner diameters. The first hose 1 and the second hose 2 are respectively fitted onto the two ends of the connecting tube 3, with the inner wall of the connecting tube 3 tightly fitting against the outer wall of the hose. Next, the upper locking shell 41 and the lower locking shell 45 are respectively fastened onto the outer surfaces of the first hose 1 and the second hose 2, covering the connection between the hose and the connecting tube 3. Then, the threaded rod 44 is rotated, allowing it to pass through the threaded hole 43 of the fixing block 42 and engage with the threaded structure of the lower locking shell 45. The threaded rod 44 is then tightened further, causing the upper locking shell 41 and the lower locking shell 45 to gradually move closer together until the rubber anti-slip pad 46 on the inner wall tightly adheres to the outer surface of the hose. At this point, the rubber anti-slip pad 46 both restricts the axial sliding of the hose through friction and fills the gap through elastic deformation, achieving overall locking. To ensure a tight seal and prevent hose detachment and leakage, the secondary locking mechanism 5 provides precise local reinforcement for hoses of different inner diameters, further enhancing adaptability and stability. The flexible locking ring 51 is fitted onto the outside of either the first hose 1 or the second hose 2. The elastic material of the flexible locking ring 51 adapts to the inner diameter of the hose, initially fitting the hose. Then, based on the actual inner diameter of the hose, the locking rod 53 is inserted into the corresponding locking hole 52 on the outer surface of the flexible locking ring 51. By selecting different positions of the locking hole 52, the tightening degree of the flexible locking ring 51 is adjusted to ensure sufficient clamping force for hoses of different inner diameters. Finally, the locking rod 53 is tightened, causing the flexible locking ring 51 to further contract and tightly fit the outer surface of the hose, forming a double lock with the main locking mechanism 4. This prevents the hose from shaking due to water pressure impact and further enhances the sealing performance, making it particularly suitable for large-diameter hoses or high-pressure water supply scenarios.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
