Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment, and in particular to a hose coupling anti-detachment mechanism. Background Technology

[0002] In the handling of building fires, especially high-rise building fires, the reliability of the connection of fire hoses, as water delivery components, is directly related to the efficiency and safety of firefighting operations. Fire hoses usually need to be connected in multiple sections through interfaces to adapt to the distance requirements of different fire scenes and ensure that firefighting water can be accurately and continuously delivered to the fire area. Therefore, the connection stability and structural protection of hose interfaces have become one of the key factors to ensure the smooth progress of fire fighting.

[0003] Conventional fire hose connections rely solely on their own plug-in or threaded structure for connection and fixation. In actual fire response scenarios, especially in situations where fire hoses need to be suspended vertically, such as high-rise building fires, the hose connections are susceptible to external force fluctuations, water flow impacts, or collisions, which can lead to loosening or even detachment of the connection, resulting in water supply interruption and seriously affecting the progress of firefighting operations. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a hose connector anti-detachment mechanism, which aims to improve the problem that conventional fire hose connectors in the prior art are fixed by plugging or threading, which are prone to loosening and falling off in fire fighting, especially in the case of vertical suspension in high-rise buildings, leading to water supply interruption.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hose interface anti-detachment mechanism, comprising a hose body, wherein the hose body is composed of two sets, the two sets of hose bodies are fixedly connected through an installation interface, the outer wall of the hose body is provided with an anti-detachment component, and the installation interface is provided with a protective component. The anti-detachment component includes two sets of mounting rings fixedly connected to the outer wall of the hose body. The two sets of mounting rings are evenly distributed along the axial direction of the two sets of hose bodies. The inner wall of the mounting ring is provided with a mounting hole.

The upper and lower ends of the chain and the connecting belt are fixedly connected with locking hooks.

[0006] As a further description of the above technical solution: The protective component includes a buffer pad, a connecting plate fixedly connected to the right surface of the buffer pad, mounting plates symmetrically fixedly connected to the upper and lower ends of the right surface of the connecting plate, a slot opened at the rear end of the right surface of the mounting plate, and an insert block fixedly connected to the front end of the right surface of the mounting plate. A fixing bolt is threaded through and threaded onto the upper surface of the insert block.

[0007] As a further description of the above technical solution: The locking hook at the lower part of the connecting belt is fixedly installed at the mounting hole of the mounting ring at the lower position, and the locking hook at the upper part of the chain is fixedly installed at the mounting hole of the upper mounting ring.

[0008] As a further description of the above technical solution: The locking hook at the top of the connecting belt is fixedly installed in the middle section of the chain.

[0009] As a further description of the above technical solution: The mounting holes, locking hooks, chains, and connecting straps are provided in multiple sets, and the multiple sets of mounting holes, locking hooks, chains, and connecting straps are arranged in a circular array with the center of the mounting ring as the origin.

[0010] As a further description of the above technical solution: The protective components are provided in two sets, and the two sets of protective components are arranged in a ring array with the center point of the installation interface as the origin.

[0016] 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.

[0017] Reference Figures 1-3 The present invention provides an embodiment of a hose connector anti-detachment mechanism, comprising a hose body 1, which is used to transport water for handling building fires. The hose body 1 consists of two sets, which are fixedly connected by an installation interface 2. The installation interface 2 can enable quick connection of the hose body 1 to flexibly adjust the length of the hose to suit different fire scenes. The outer wall of the hose body 1 is provided with an anti-detachment component 3, and the installation interface 2 is provided with a protective component 4.

[0018] Reference Figures 1-3The anti-detachment component 3 includes two sets of mounting rings 31 fixedly connected to the outer wall of the hose body 1. The two sets of mounting rings 31 are evenly distributed along the axial direction of the two hose bodies 1. The mounting rings 31 are the mounting base of the anti-detachment component 3. The mounting rings 31 are made of metal, with an inner ring diameter of about 70 mm and a thickness of 10 mm. The inner wall of the mounting rings 31 has a through mounting hole 32 for connecting the locking hook 33. A chain 34 is provided below the upper mounting ring 31. The chain 34 has excellent tensile and bending resistance to maintain the connection stability of the hose body 1. A connecting strap 35 is provided above the lower mounting ring 31. The connecting strap 35 has good flexibility and toughness. Locking hooks 33 are fixedly connected to both the upper and lower ends of the chain 34 and the connecting strap 35. The locking hooks 33 are detachable connecting parts, which can realize the connection between the chain 34 and the connecting strap 35. The quick assembly and disassembly between the connecting strap 35 and the mounting ring 31 ensures the reliability of the connection structure and prevents the connecting parts from falling off. The locking hook 33 on the upper part of the chain 34 is fixedly installed at the mounting hole 32 of the upper mounting ring 31, and the locking hook 33 on the lower part of the connecting strap 35 is fixedly installed at the mounting hole 32 of the lower mounting ring 31. The locking hook 33 on the upper part of the connecting strap 35 is fixedly installed in the middle section of the chain 34. By changing the position of the locking hook 33 on the upper part of the connecting strap 35 connected to the middle section of the chain 34, the total length of the connecting strap 35 and the chain 34 can be adjusted. Multiple sets of mounting holes 32, locking hooks 33, chains 34, and connecting straps 35 are provided. Multiple sets of mounting holes 32, locking hooks 33, chains 34, and connecting straps 35 are arranged in a circular array with the center of the mounting ring 31 as the origin. The circular array layout can ensure that the components are evenly stressed.

[0019] Reference Figures 1-2 In actual use, the upper locking hook 33 on the chain 34 can also be installed on the building or other support equipment to achieve support. During installation, it is only necessary to install the lower locking hook 33 on the connecting belt 35 at the mounting hole 32 on the lower mounting ring 31.

[0020] Reference Figure 1 , Figure 3 , Figure 4The protective component 4 includes a buffer pad 41 made of rubber, which provides cushioning protection when subjected to rigid impact. In high-rise building fires, the hose body 1 is often vertically perpendicular to the ground. When subjected to external forces, the hose body 1 and the mounting interface 2 will shake, making them prone to collisions with external objects. A connecting plate 42 is fixedly connected to the right surface of the buffer pad 41. The connecting plate 42 acts as a connection between the buffer pad 41 and the mounting plate 43, providing rigid support for the buffer pad 41. Mounting plates 43 are symmetrically fixedly connected to the upper and lower ends of the right surface of the connecting plate 42. The adjacent surfaces of the two sets of mounting plates 43 abut against the upper and lower surfaces of the mounting interface 2. A slot 44 is provided at the rear end of the right surface of the mounting plate 43. A plug 45 is fixedly connected to the front end of the right surface. The plug 45 is inserted into the inner wall of the slot 44. The edge of the plug 45 near the slot 44 is chamfered. The chamfer can guide the plug 45 to be quickly and accurately inserted into the slot 44. The mounting plate 43 and the plug 45 are both provided with threaded holes on the side away from the center of the mounting interface 2. The upper surface of the plug 45 is threaded with a fixing bolt 46. The fixing bolt 46 is threaded on the side of the mounting plate 43 away from the center of the mounting interface 2. The mounting plate 43 and the plug 45 can be fixedly installed through the threaded holes on the surface and the fixing bolt 46. Two sets of protective components 4 are provided. The two sets of protective components 4 are arranged in a ring array with the center point of the mounting interface 2 as the origin.

[0021] Working principle: In use, the two sets of hose bodies 1 are first connected through the installation interface 2. The two sets of installation rings 31, which are fixedly connected to the outer wall of the hose body 1, serve as the basic load-bearing structure. The installation holes 32 on their inner walls provide connection points for the locking hooks 33. The locking hooks 33 on the upper part of the chain 34 are connected to the installation holes 32 of the upper installation rings 31, and the locking hooks 33 on the lower part of the connecting belt 35 are connected to the installation holes 32 of the lower installation rings 31. Then, the chain 34 is connected to the connecting belt 35 by fixing the locking hooks 33 on the upper part of the connecting belt 35 to the middle section of the chain 34. By adjusting the connection position of the locking hooks 33 on the upper part of the connecting belt 35 in the middle section of the chain 34, the total length of the connecting belt 35 and the chain 34 can be changed to adapt to the pulling length requirements in different scenarios.

[0022] In actual use, the installation position of the upper lock hook 33 on the chain 34 can be adjusted according to actual needs. If there is a supporting building or equipment, the connection can be completed by installing the upper lock hook 33 on the supporting building or equipment.

[0023] When the mounting interface 2 is impacted, the buffer pad 41 can absorb the impact force through its own elastic deformation, reduce the wear of the mounting interface 2, and prevent the mounting interface 2 from deforming due to the impact.

[0024] When installing the protective component 4, the two sets of protective components 4 are first spliced ​​by the insertion of the plug 45 and the slot 44. The chamfer on the edge of the plug 45 facilitates splicing and assembly. After the assembly is completed, the fixing bolt 46 is used to lock and fix the mounting plate 43 through the threaded hole on the surface of the plug 45, thereby realizing the installation of the protective component 4 and protecting the installation interface 2.

[0025] 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.
