Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire hose technology, specifically a quick-assembly fire hose. Background Technology
[0002] Fire hoses are commonly used tools by firefighters during rescue operations. They are flattened when rolled up for easy storage. After being taken out of the casing, they can be connected to fire hydrants or the water tanks on fire trucks to draw liquid and spray it from the nozzle to extinguish open flames or cool hot objects.
[0003] Both ends of the fire hose are equipped with metal components for assembly. They need to be spliced to bring the water source to another location. However, in the past, fire hoses were assembled only by threads and grooves. If the water pressure was too high, the lack of reinforcement between the surfaces of the hose body would easily cause it to crack and separate the metal fittings from the hose body.
[0004] Now, a new type of quick-assembly fire hose is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a quick-assembly fire hose to solve the problem of difficult hose splicing mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-assembly fire hose, comprising a hose body and a splicing ring one, wherein the splicing ring one is fixed on the left side of the hose body, and the splicing ring two is fixed on the right side of the hose body; splicing blocks are welded to the upper and lower parts of the outer surface of the splicing ring one, and a pin is fixed to the left side of the splicing block; a limiting rod is hinged between the front and rear parts inside the pin, and an engagement piece is welded to the surface of the limiting rod; a positioning bolt is threaded into the engagement piece; and sleeve blocks are welded to the upper and lower parts of the outer surface of the splicing ring two, and insertion holes are provided between the two sides inside the sleeve blocks.
[0007] Preferably, the sleeve block and the splicing block are on the same horizontal plane, and the pin is embedded in the socket.
[0008] Preferably, the limiting rod can rotate up and down in the left chamber of the pin, and the right side of the limiting rod is attached to the surface of the splicing ring two.
[0009] Preferably, the surface of the belt is fitted with two sets of fixing rings, and the inner wall of the fixing ring is provided with a collar. The top of the fixing ring is fixed with a hinge block. A sleeve is hinged between the front and back sides of the inner side of the hinge block. A reinforcing bolt is engaged with the front end of the hinge block. A thin rod is movably inserted into the inside of the sleeve. A handle is welded to the bottom of the fixing ring.
[0010] Preferably, the fixing ring and the belt are arranged in concentric circles, and the thin rod and the sleeve are arranged in concentric circles.
[0011] Preferably, the sleeve can swing left and right in the hinge block, and the sleeve can slide back and forth along the outer wall of the thin rod.
[0012] Preferably, the inner side of the belt body is provided with an inner cavity, and the front and rear of both sides of the inner cavity are respectively equipped with a stop block, and the side of the stop block is provided with a sealing plate. The stop block and the sealing plate are respectively provided with screw holes, and fastening bolts are threaded into the screw holes.
[0013] Preferably, the sealing plate and the belt body are on the same horizontal plane, and the fastening bolt is embedded between the stop block and the sealing plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are: this quick-assembly fire hose not only realizes the quick splicing of fire hose and the easy bending of the pipe body, but also realizes the closed and restricted hose body;
[0015] (1) By fixing a splicing ring one on the left side of the belt body, two adjacent belt bodies are assembled together by splicing ring one and splicing ring two on the left and right sides. The splicing block is guided to pass through the insertion hole of the sleeve block with a pin, and then the limiting rod is rotated and locked on the surface of splicing ring two by passing through the meshing plate, forming a snap-fit fixed mode, which distributes the pressure on splicing ring one and splicing ring two evenly, and also realizes quick assembly and disassembly, and extends the distance of the belt body;
[0016] (2) By assembling two sets of fixing rings on the surface of the belt, the distance between the sleeves on both sides of the thin rod is adjusted, and the hinge block and the sleeve are locked with reinforcing bolts to prevent the sleeve from continuing to rotate. The flat belt can be pulled into a 90-degree right angle by the sleeve. The fixing ring is also fixed by the collar, which can assist the belt in bending and changing the liquid delivery direction. The presence of the handle also makes it convenient for the user to hold.
[0017] (3) By setting a sealing plate on the side of the block, the belt will be wound into a circle when idle and stored in the fire cabinet. Symmetrical blocks are set in the inner chambers on both sides of the belt. The sealing plate is placed in the belt and then the corresponding screw hole is aimed and locked with the fastening bolt. This will prevent the sealing plate from sliding out of the belt, avoid the belt from being mixed with foreign objects and affecting its use, and prevent the water gun from being sprayed out by excessive pressure and causing damage.
