[0030] Embodiment 1

[0031] This embodiment provides a quick-installation central fastener for a fire hose, as Figures 1 - 4As shown in the figure, it includes a first fastener 1 and a second fastener 2. One end of the open side of the first fastener 1 is rotatably connected to the same-side end of the second fastener 2, and the other end of the open side of the first fastener 1 is rotatably connected to a locking mechanism 3. The locking mechanism 3 can lock and fix the first fastener 1 and the second fastener 2 in the buckled state. After buckling, a fixing hole 4 for the outlet of the fire hose pipeline is formed between the first fastener 1 and the second fastener 2.

[0032] In this embodiment, the first fastener 1 is made of a U-shaped plate, including a first plate portion, a second plate portion provided on one side of the first plate portion, and a third plate portion provided on the other side of the first plate portion. The first plate portion serves as the closed side of the first fastener, and the other end of the first fastener serves as the open side.

[0033] A pin shaft 5 is provided between one ends of the second plate portion and the third plate portion on the open side, and is rotatably connected to the same-side end of the second fastener 2 through the pin shaft 5.

[0034] In this embodiment, the second fastener 2 is also made of a U-shaped plate, including a first buckling portion, a second buckling portion and a third buckling portion respectively provided on both sides of the first buckling portion. The second buckling portion and the third buckling portion are respectively located outside the second plate portion and the third plate portion. The pin shaft 5 is fixed between the second plate portion and the third plate portion. The pin shaft 5 passes through the second plate portion and the third plate portion, and the second buckling portion and the third buckling portion are rotatably connected to the pin shaft 5, thereby realizing the rotational connection between the second fastener 2 and the first fastener 1.

[0035] The second plate portion and the third plate portion are provided with grooves at the ends on the open side, and the second buckling portion and the third buckling portion are also provided with corresponding grooves at the ends facing the first fastener. After the first fastener 1 and the second fastener 2 are buckled, the fixing hole 4 for the pipeline outlet is formed through the grooves for fixing the pipeline outlet of the fire hose.

[0036] The right end of the open side of the first fastener is rotatably connected to one end of the second fastener 2, and the other end of the open side of the first fastener 1 is rotatably connected to a locking mechanism 3. The locking mechanism 3 includes a rotating plate, and the rotating plate is also made of a U-shaped plate, including a first rotating portion, a second rotating portion and a third rotating portion respectively provided on both sides of the first rotating portion. A pin shaft is fixed between the second plate portion and the third plate portion at this end of the first fastener. The pin shaft passes through the second plate portion and the third plate portion, and the second rotating portion and the third rotating portion are respectively rotatably connected to both ends of the pin shaft to realize the rotational connection between the rotating plate and the first fastener. A locking member is threadedly connected to the first rotating portion. Preferably, the locking member is a locking bolt.

[0037] In the buckled state of the first fastener 1 and the second fastener 2, the rotating plate can rotate until the first rotating portion is located outside the second fastener 2. By rotating the locking bolt, the second fastener 2 can be tightened by the locking bolt, so that the first fastener 1 and the second fastener 2 are locked and fixed. Preferably, the locking bolt is a butterfly bolt.

[0038] On both edges of the third plate portion perpendicular to the first plate portion, there are first fixing plates 6 provided. The first fixing plates 6 are provided with first fixing holes, and the entire central fastener can be fixed to the wall or ceiling through the first fixing holes and fixing bolts.

[0039] The above structure can adopt the technical solution disclosed in patent application CN118110843A. The further technical details are not described in detail herein. On the basis of the technical solution disclosed in patent application CN118110843A, this embodiment is improved by adding a second fixing plate and a limiting plate, opening fixing pipe holes on the second plate portion and the third plate portion, and threadedly connecting a locking member to the first plate portion.

[0040] Specifically, a second fixing plate 7 is provided on the outer side surface of the first plate portion. Preferably, second fixing plates 7 are provided at both ends of the outer side surface of the first plate portion. The second fixing plate 7 adopts an L-shaped plate, including a first fixing portion and a second fixing portion that are perpendicular to each other. One end of the first fixing portion is welded and fixed to the end of the first plate portion, and the other end is perpendicularly connected to the second fixing portion. The second fixing portion is arranged parallel to the first plate portion, and a second fixing hole is provided on the second fixing portion. The axis of the second fixing hole is perpendicular to the axis of the first fixing hole and the first plate portion.

[0041] The entire central fastener can be fixed to the wall or ceiling through the second fixing hole and the fixing bolt.

[0042] Corresponding fixing pipe holes 8 are opened on the second plate portion and the third plate portion. In this embodiment, the fixing pipe holes 8 adopt square holes. Correspondingly, the fixing pipes adopt square pipes. The square pipes can pass through the first fastener 1 through the fixing pipe holes. The ends of the square pipes are fixed to the ceiling or the wall through bolts, thereby realizing the hoisting setting of the entire central fastener.

[0043] A threaded locking hole 9 is provided on the first plate portion, and a locking member is threadedly connected through the threaded locking hole. The locking member adopts a locking bolt, preferably a wing nut bolt. The rod portion of the locking bolt can press against the square pipe, so that the central fastener is locked and fixed to the square pipe.

[0044] Limiting plates 10 are provided on both edges of the second plate portion or the third plate portion perpendicular to the first plate portion. Preferably, limiting plates 10 are provided on both edges of the second plate portion perpendicular to the first plate portion. The limiting plates 10 are perpendicular to the second plate portion, and there is a set distance between the limiting plates 10 and the first plate portion to form a space for the fixing pipe to pass through. The fixing pipe can pass through the space between the limiting plates 10 and the first plate portion, and then is locked and fixed by the locking bolt on the first plate portion.

[0045] When the central fastener of this embodiment is applied in the first application scenario:

[0046] This application scenario has no keel. For example, Figure 5 As shown, the base 12 at the end of the square pipe 11 is fixed to the ceiling 13 by bolts according to the installation position. The square pipe 1 passes through the first fastener 1 through the fixing pipe hole 8, and the first fastener 1 is locked and fixed to the square pipe 11 using a locking bolt, so that the central fastener is hoisted on the square pipe 11. Then, the pipe outlet 14 of the fire hose is inserted into the fixing hole 4 of the pipe outlet formed by the first fastener 1 and the second fastener 2 of the central fastener. Then, the first fastener 1 and the second fastener 2 in the buckled state are locked and fixed using the locking mechanism 3, and the installation of the fire hose is completed.

[0047] For example, Figure 6 As shown, when the ceiling height is relatively high and it is inconvenient to fix the square pipe to the ceiling, the base 12 at the end of the square pipe 11 is fixed to the wall 15 by bolts according to the installation position. The square pipe passes through the first fastener through the space between the limiting plate and the first plate body, and the first fastener is locked and fixed to the square pipe using a locking bolt, so that the central fastener is hoisted on the square pipe. Then, the pipe outlet of the fire hose is inserted into the fixing hole of the pipe outlet formed by the first fastener and the second fastener of the central fastener. Then, the first fastener and the second fastener in the buckled state are locked and fixed using the locking mechanism, and the installation of the fire hose is completed.

[0048] When the central fastener of this embodiment is applied in the second narrow space scenario without keel and where the square pipe cannot be used:

[0049] For example, Figure 7 As shown, after first finding a suitable installation position for the pipe outlet 14 of the fire hose, the central fastener is fixed to the ceiling through the first fixing hole and bolts. Then, the pipe outlet of the fire hose is inserted into the fixing hole 4 of the pipe outlet formed by the first fastener 1 and the second fastener 2 of the central fastener. Then, the first fastener 1 and the second fastener 2 in the buckled state are locked and fixed using the locking mechanism 3, and the installation of the fire hose is completed. In this application scenario, the pipe outlet is perpendicular to the ceiling.

[0050] When applied in another narrow space scenario, for example, Figure 8 As shown, after first finding a suitable installation position for the pipe outlet 14 of the fire hose, the central fastener is fixed to the wall through the second fixing hole and bolts. Then, the pipe outlet 14 of the fire hose is inserted into the fixing hole 4 of the pipe outlet formed by the first fastener 1 and the second fastener 2 of the central fastener. Then, the first fastener 1 and the second fastener 2 in the buckled state are locked and fixed using the locking mechanism 3, and the installation of the fire hose is completed. In this application scenario, the pipe outlet is parallel to the wall.

[0051] For the central fastener of this embodiment, the first fastener 1 can be installed perpendicular to the ceiling or wall, meeting the application scenario requirements that the fire hose outlet in a narrow space is parallel to the ceiling or wall. The fixed pipe can be arranged parallel to the first fastener or perpendicular to the first fastener through the fixed pipe hole, further broadening the application scenarios of the central fastener and improving its applicability.

[0052] Although the specific implementation manners of the present invention have been described above in conjunction with the accompanying drawings, they do not limit the protection scope of the present invention. Those skilled in the art should understand that based on the technical solutions of the present invention, various modifications or deformations that can be made without creative efforts by those skilled in the art are still within the protection scope of the present invention.
