Description

Technical Field

[0001] The invention discloses a fire hose reel, in particular to a fire hose reel capable of preventing the hose from loosening. Background Art

[0002] Fire hose reels are generally installed in indoor fire hydrant boxes. Fire hoses are usually made of rubber, canvas, plastic and other materials. They are light, soft and easy to carry. They are mainly used to connect fire hoses and fire hoses and other equipment. They can withstand greater pressure and flow. They are important transportation tools in fire fighting and rescue. There are many types of fire hoses, including canvas fire hoses. No matter which type of hose, it needs to be reeled onto the reel after normal use.

[0003] In the prior art, when a fire hose is used, since it is used for fire rescue, the overall length of the fire hose is relatively long during design to ensure effective use; after use, the hose needs to be rewound around the reel rod in the fire hydrant, and the operation is inconvenient and slow when reeling again; in order to speed up efficiency and facilitate taking out, the middle reel rod is set to rotate relative to the fire hydrant to achieve the effect of convenient taking out and reeling, but after reeling, it is easy to loosen due to relative rotation; at the same time, the fire hydrant is not completely closed, so it is easy to be opened, especially some children are curious about the unknown, and are easy to play with it, resulting in the looseness of the folding and confusion during use, which makes it difficult to assemble and use, so it is necessary to fix the hose to avoid looseness; but after fixing, it is necessary to release the fixation first to take it out, if the fixation is cumbersome, then the release is also cumbersome, which will affect the rescue and use efficiency, on the contrary, if it is simply fixed, it is easy to release and it will still be easy to take out, so another solution is proposed, which makes the fixation simple and fast, and the take-out and use is also convenient and fast, and does not affect the rescue use.

The fixed block one is rotatably connected to the fixed bracket, and a worm is rotatably connected in the fixed bracket, and a worm wheel meshing with the worm is provided in the fixed bracket. A pull rope for pulling the worm to rotate is provided on the fixed block one, and a gear meshing with the rotating wheel is clamped on the worm wheel. An annular spring sheet is provided between the worm and the fixed block, and the elastic force of the spring sheet is equal to that of the spring.

[0007] Preferably, the second fixing block is provided with a switch 2 for controlling the motor 1 to be turned off, and the fixing bracket is provided with a protrusion on the side of the kit, and a gap is formed between the protrusion and the kit to accommodate the hose passing through.

[0008] Preferably, a pushing block for pushing the hose to unfold is provided on one side of the fixed block, and one side of the pushing block is inclined. A raised rubber strip is provided in the middle of the hose, and cavities are formed on both sides of the hose and the rubber strip after the kit is wrapped around. A small fan is provided on the upper end of the magnetic block of the kit, and the fan is turned on and off synchronously with the motor 1, and the cavity accommodates gas to enter. The height of the gap between the fixed block 1 and the fixed block 2 is consistent with the thickness of the rubber strip after the hose is fitted.

[0009] Preferably, a limit block is provided on the outer side of the second fixed block, which is embedded in the first fixed block and limits the outward rotation of the first fixed block. The limit block is slidably connected to the first fixed block and the second fixed block. A slot is provided on the fixed bracket to accommodate the rotation and embedding of the first fixed block. Stop blocks are provided on both sides of the slot, which abut against the first fixed block and limit the first fixed block. The stop block is rotatably connected to the fixed bracket, and a torsion spring is provided between the stop block and the fixed bracket.

[0012] Preferably, the front and rear ends of the front and rear inner walls of the limiting groove and the abutting surfaces of the plug-in are arc surfaces, and the side of the plug-in where it is embedded in the limiting groove is also an arc surface, and a spring three is provided between the pressing block and the baffle.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] First, after using this device, the end of the hose connected to the fire-fighting joint is adsorbed to the magnetic block, and after the hose passes through the gap between the protrusion and the set, the switch 1 is also pressed to turn on the motor 1, so that the motor 1 drives the set to rotate, so that the hose is continuously rolled up, thereby achieving the effect of automatically rolling up the hose, and while rolling up, the thickness is continuously increased, which pushes the clamping block upward and compresses the spring 1, and the rolling force of the motor 1 is greater than the elastic force of the spring 1, ensuring that the rolling can overcome the elastic force of the spring 1, and after the rolling is completed, the clamping block is pushed by the elastic force of the spring 1 to limit the hose from being easily pulled out, and the elastic force of the spring 1 is greater than the pulling force of an ordinary child, so that it is not easy to loosen after rolling up;

[0015] Secondly, after the reeling, the joint at the other end of the hose will directly contact the fixing block 1 and the fixing block 2, and when it fits the fixing block 2, the switch 2 will be pressed, and the switch 2 will control the motor 1 to be turned off, so as to stop the reeling and achieve the effect that the motor 1 stops rotating after the reeling is completed. Secondly, after the pressing block moves up, it will drive the connecting rod to move up and rotate along the middle to drive the other end to move down, pushing the baffle to move downward, blocking the effect of the upper end of the hose and the pressing block fitting together, because the upper end of the hose and the pressing block will fit more loosely, and the hose near the center is also tightly fitted due to the reeling and is not easy to pull out, ensuring that the hose and the outer ring of the pressing block are not easily pulled out directly from the side, thereby reducing the loose situation and avoiding the situation of being directly pulled out by curious people;

[0016] When the fire extinguisher needs to be taken out, the joint connected between the hose and the magnetic block is connected to the fire extinguisher joint, and then the limit block on the fixed block second is pushed backward to disengage the fixed block one and rotate the fixed block one upward to embed it into the blocking block inclined surface along the blocking block on both sides of the slot, and the blocking block is pushed and rotated to compress the torsion spring, thereby embedding it into the slot and being restricted by the blocking block. At this time, after the pulling of the pull rope is cancelled, the restriction of the pull rope that the worm is separated from the worm, and the elastic force of the internal spring sheet will push the worm to rotate and drive the meshing worm wheel to rotate, and when the worm wheel rotates, it also drives the engaged gear to rotate together, and when the gear rotates, it will drive the meshing driving wheel to rotate, and the meshing transmission wheel will rotate synchronously, so that the connecting rope is reeled in and the tightening block continues to move upward, so that the tightening block cancels the squeezing and tightening of the hose, thereby the hose is freed from the restraint and can be directly pulled out when needed to be used, which can easily drive the hose to rotate. The reeling and tightening after the arrangement is not easy to loosen, and it is convenient, simple and quick to use, and will not reduce the rescue efficiency. The installation method is still the connection between the joints. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] A fire hose reel that prevents loosening, such as Figure 1-Figure 7As shown, it includes a fire hydrant shell, in which a fixed bracket 1 and a hose 2 are arranged, the fixed bracket 1 is rotatably connected with a kit 3 for winding up the hose 2, the kit 3 is provided with a fire connector connected to the hose 2, the fixed bracket 1 is slidably connected with a plurality of clamping blocks 4 for clamping the hose 2, a high-elasticity spring 5 is provided between the clamping block 4 and the fixed bracket 1, the fixed bracket 1 is provided with a motor 6 for driving the kit 3 to rotate and reel up the hose 2, a magnetic block 7 adsorbed with the hose 2 connector is provided on the outer side of the kit 3, a switch 8 for controlling the start of the motor 6 is provided in the middle of the magnetic block 7, the fixed bracket 1 is provided with a fixed block for the hose 2 to pass through, and the fixed bracket 1 is provided with a spring 5 and a clamping block for releasing the spring 5 and the clamping block. The tightening block 4 is a component for releasing the restriction on the hose 2. After normal use of this equipment, the hose 2 is wound around the reeled kit 3, and the kit 3 is driven to rotate manually or automatically, so that the hose 2 is automatically reeled up and neatly stored, so as to facilitate continued use next time. However, because the fire hydrant is not closed and cannot be opened, some communities, schools or public places will curiously open it, and take out the cartilage hose to check or even play with it, which will cause the hose 2 to become loose and not neatly re-stored. Therefore, in the prior art, the hose 2 will be fixed after being reeled up, but the above situation will still occur with simple fixing. If the fixing is cumbersome and cannot be opened, it will affect or even delay the rescue use when it needs to be reused when encountering fire problems.

[0027] After using this device, the entire fixed bracket 1 is set in the fire hydrant for use, and the water outlet of the fire hydrant passes through the entire fixed bracket 1. When normally reeling, the end of the hose 2 connected to the fire connector is passed along the upper surface of the fixing block 2 14 and the fixing block 1 13 is buckled, so that the hose 2 can only pass between the fixing block 1 13 and the fixing block 2 14, and then the connector of the hose 2 is directly adsorbed to the magnetic block 7, and the hose 2 passes through the gap between the protrusion 21 and the kit 3 to achieve fixation. While fixing, the switch 1 8 will be turned on, and the control motor 1 6 will start to drive the kit 3 to rotate and reel the hose 2. At the same time, the moving hose 2 only moves along the space between the fixing block 13 and the fixing block 2 14. To ensure the regularity of winding, the tightening block 4 will not be continuously pushed upward due to the increase in thickness during winding. After the compression spring 15 is waited for the winding to be completed, the joint at the outer end of the hose 2 will directly fit on the fixed block 13 and the fixed block 2 14, thereby turning on the switch 20 on the fixed block 2 14, so that the motor 1 6 is turned off to achieve the effect of stopping the winding. After stopping the winding, the elastic force of the spring 15 is relatively large and greater than the pulling force of a normal child. Therefore, the tightening block 4 is pushed by the elastic force of the spring 15 to tighten the hose 2, ensuring that the hose 2 is not easily pulled out, thereby avoiding the loose situation. Normally, older children have sufficient cognition and will not accidentally touch and play with it, while younger children do not pull it. Therefore, the loose situation can be reduced by this setting.

[0028] The release assembly includes a rotating rod 9 rotatably connected to the fixed bracket 1 at the upper end of a spring 5, a connecting rope 10 is wound around the rotating rod 9, one end of the connecting rope 10 is connected to the rotating rod 9 and the other end passes through the spring 5 and is connected to the tightening block 4, a transmission wheel 11 is fixedly connected to the rear end of the rotating rod 9, a rotating wheel 12 meshing with the transmission wheel 11 is provided on the fixed bracket 1, the fixed block is divided into a fixed block 13 and a fixed block 2 14, the fixed block 13 is rotatably connected to the fixed bracket 1, a worm 15 is rotatably connected inside the fixed bracket 1, a worm wheel 16 meshing with the worm 15 is provided inside the fixed bracket 1, a pull rope 17 for pulling the worm 15 to rotate is provided on the fixed block 13, and a gear meshing with the rotating wheel 12 is clamped on the worm wheel 16 18, an annular spring sheet 19 is provided between the worm 15 and the fixed block, the elastic force of the spring sheet 19 is equal to that of the spring 15, a switch 20 for controlling the motor 6 to be turned off is provided on the fixed block 14, a protrusion 21 is provided on the side of the fixed bracket 1 located at the kit 3, and a gap for accommodating the hose 2 to pass through is formed between the protrusion 21 and the kit 3, and secondly, the restriction of the spring 15 makes it inconvenient to pull, so as to avoid the situation that the pulling is laborious and the use efficiency is reduced when fire rescue occurs. When it is necessary to pull and take, the fixed block 13 can be pushed upward and fixed first, so as to cancel the pulling of the pull rope 17, and the pull rope 17 cancels the pulling of the worm 15. After the worm 15 is free from the restriction of the pull rope 17, the internal The elastic force of the spring leaf 19 will push the worm 15 to rotate, thereby driving the meshing worm wheel 16 to rotate, and synchronously driving the connected gear 18 to rotate, so that the gear 18 drives the meshing rotating wheel 12 to rotate together, thereby driving the transmission wheel 11 connected to the rotation in the fixed bracket 1 to rotate, so that the transmission wheel 11 drives the connected rotating rod 9 to rotate, because the compression of the spring 15 and the upward movement of the clamping block 4 will make the connecting rope 10 loose, at this time, after the rotating rod 9 rotates, it will have the effect of rewinding the connecting rope 10, and the clamping block 4 will be pulled upward to cancel the restriction on the hose 2, and at this time, the joint on the outside of the hose 2 will be pulled, so that when it is needed, just pull the fixed block 13 upward Opening it can remove the restriction and facilitate pulling it out to take it out. Secondly, through normal installation, you only need to fix one end of the hose 2 connected to the fire connector, press the fixing block 13 downward and pull the pull rope 17 again to drive the worm 15 to reset, and simultaneously drive the meshing worm gear 16 to rotate and drive the engaged gear 18 to drive the rotating wheel 12, and then drive the transmission wheel 11 to rotate so that the rotating rod 9 cancels the winding of the connecting rope 10. At the same time, after the tightening block 4 is released from the restriction, the spring 5 pushes it to reset, ensuring that the hose 2 can still be tightened after being wound again. Compared with the prior art, the hose 2 is restricted to ensure that it is not easy to loosen, and it is convenient and quick to take and will not affect the use of fire fighting.

[0029] A push block 22 for pushing the hose 2 to unfold is provided on the side of the fixed block 13. One side of the push block 22 is inclined. A raised rubber strip 23 is provided in the middle of the hose 2. After the hose 2 and the rubber strip 23 are wrapped around the kit 3, a cavity is formed on both sides. The kit 3 is provided with a small fan 24 at the upper end of the magnetic block 7. The fan 24 is turned on and off synchronously with the motor 16. The cavity accommodates gas to enter. The height of the gap between the fixed block 13 and the fixed block 2 14 is consistent with the thickness of the rubber strip 23 after the hose 2 is attached. When the end of the hose 2 connected to the fire connector is adsorbed on the magnetic block 7, the switch 8 will synchronously turn on the fan The fan 24 is turned on, and the joint of the hose 2 is opposite to the fan 24, so that the gas blown out by the fan 24 enters the hose 2, and the hose 2 is supported by the middle rubber strip 23 and squeezed by the pressing block 4, and there are certain cavities on both sides to accommodate the flow of gas, so that the gas will be discharged outward. Therefore, the hose 2 will be stretched a little by the outside of the fixing block 13 and the fixing block 2 14, and at the same time, the gas will be squeezed out by passing through the fixing block 1 13 and the fixing block 2 14. Therefore, the folded parts that are not carefully arranged after use will be stretched and flattened by the gas, so that the winding can be more neat and flat.

[0030] A limit block 25 is provided on the outer side of the fixed block 14, which is embedded in the fixed block 13 and limits the fixed block 13 from rotating outward. The limit block 25 is slidably connected with the fixed block 13 and the fixed block 14. A slot 26 is provided on the fixed bracket 1 to accommodate the rotation and embedding of the fixed block 13. Stop blocks 27 are provided on both sides of the slot 26 to abut against the fixed block 13 and limit the fixed block 13. The stop block 27 is rotatably connected to the fixed bracket 1, and a torsion spring 28 is provided between the stop block 27 and the fixed bracket 1. The surface of the stop block 27 abutting against the fixed block 13 is an inclined surface. At the same time, after the fixed block 13 is rotated downward and buckled, it is avoided to be pulled upward by the spring sheet 19 to reset. When doing so, the limit block 25 can be first embedded in the fixed block 13 to limit the fixed block The situation that one 13 is pulled upward occurs. Secondly, after the fixed block 13 is rotated upward to open, it can first abut against the inclined surface of the blocking block 27 and push the two blocking blocks 27 to both sides to rotate and compress the torsion spring 28 to ensure that after the fixed block 13 fits the card slot 26, the blocking block 27 will be pushed again by the torsion spring 28 to limit the fixed block 13 from falling downward. Therefore, when using it to pull outward, it is only necessary to move the limit block 25 backward and still press the fixed block 13 upward. When installing, it is only necessary to push the blocking block 27 to both sides, still rotate the fixed block 13 downward to a position where it cannot rotate, and move the limit block 25 into the fixed block 13 again. Better fixing and limiting effects can be achieved without adding too many steps.

[0031] The fixed bracket 1 is slidably connected with a baffle 29 for blocking the hose 2 from being disengaged outwards, a connecting rod 30 is provided between the baffle 29 and the abutting block 4, the two ends of the connecting rod 30 are rotatably connected with the baffle 29 and the abutting block 4 respectively, the middle of the connecting rod 30 is rotatably connected with the fixed bracket 1, a plug-in 31 embedded in the baffle 29 is provided at the rotatable connection between the connecting rod 30 and the baffle 29, a spring 2 32 is provided between the plug-in 31 and the connecting rod 30, a limiting groove 33 for accommodating the plug-in 31 to be embedded is provided on the baffle 29, and a spring ...3 is slidably connected on the baffle 29 to push the plug-in 31 to disengage from the limiting groove The pressing block 34 of the groove 33, the front and rear ends of the front and rear inner walls of the limiting groove 33 and the abutting surfaces of the plug-in 31 are arc surfaces, and the side of the plug-in 31 embedded in the limiting groove 33 is also an arc surface. A spring 35 is provided between the pressing block 34 and the baffle 29. Finally, when the pressing block 4 is driven to move upward, the connected connecting rod 30 will be pushed upward synchronously. Because the connecting rod 30 cannot move upward and will rotate along the middle, and the upper end of the connecting rod 30 connected to the pressing block 4 moves upward and rotates along the middle, and the other end connected to the baffle 29 will rotate and move downward synchronously, thereby driving The baffle 29 moves down and blocks the upper end of the rolled-up hose 2. Because the outer ring of the rolled-up hose 2 fits against the tightening block 4, it is easier to pull it outwards. The middle part is squeezed by the weight of the continuously rolled-up hose 2 and is limited by the tightening force of the roll. The closer to the center, the more difficult it is to pull out. The baffle 29 blocks some children from directly pulling the hose 2 along the side. This arrangement further reduces the looseness and better ensures that the hose 2 will not be pulled loose. Secondly, if you need to pull the whole bundle of hose 2 When the tube 2 is taken out and used in other places, the fixing block is still moved upward and the pressing block 4 is pressed to cancel the squeezing of the hose 2, and then several pressing blocks 34 are pressed and the spring three 35 are compressed, so that the pressing block 34 pushes the plug-in 31 to synchronously compress the spring two 32 to move backward and disengage from the limiting groove 33, and the baffle 29 is separated from the connecting rod 30. At this time, the baffle 29 is moved to cancel the obstruction of the hose 2, so that the whole bundle of rolled-up hose 2 can be directly taken out without pulling it out. This setting better limits the hose 2 from being easy to loosen, and it can still be convenient for use in various situations.

[0032] After the above device is installed normally, the end of the hose 2 that needs to be connected to the fire connector is moved along the fixed block 14, and then the hose 2 is passed through the gap between the protrusion 21 and the kit 3. At the same time, the blocking block 27 is pushed to both sides to press the fixed block 13 downward. At this time, the torsion spring 28 of the blocking block 27 is canceled to push it back to its original position. After the fixed block 13 and the fixed block 2 14 are opposite, the limit block 25 is pushed to embed into the fixed block 1, so that the hose 2 connector is adsorbed on the magnetic block 7, and the switch 18 is turned on to synchronously turn on the fan 24 and the electric fan 13. The machine 6 is turned on and blows air into the hose 2 while winding it up to ensure smooth and automatic winding. The tightening block 4 is continuously pushed upward to compress the spring 5 during the winding process. After the winding is completed, the spring 5 in the tightening block 4 is squeezed to prevent the hose 2 from being easily pulled out and played with, resulting in looseness. Secondly, after the tightening block 4 moves up, it will drive the connecting rod 30 to rotate, and the one end connected to the tightening block 4 moves up and the other end moves down, and pushes the baffle to block the upper end of the hose 2 to prevent the upper end of the hose 2 from being easily pulled out near the tightening block 4. On the contrary, when in use, after the limit block 25 is pushed out of the fixed block 13, the fixed block will buckle upward and directly push the blocking block 27 backward along the inclined surface to embed into the card slot 26, so that the blocking block 27 is automatically pushed to reset and block the fixed block 13. At the same time, the spring 19 pushes the worm 15 to reset and drive the worm wheel 16 to rotate, and synchronously drives the gear 18 to drive the meshing rotating wheel 12 to rotate, and drives the transmission wheel 11 to rotate together, so that the rotating rod 9 rotates to reel in the connecting rope 10 and cancels the restriction on the hose 2, so that the firefighters can pull it more labor-savingly during use.
