Abstract
Description
Technical Field
[0001] This invention relates to the field of fire-fighting equipment technology, and in particular to a fire hose box equipped with an active release mechanism. Background Technology
[0002] Fire hose boxes are an important component of building fire protection systems. Their main purpose is to store, protect, and provide fire hoses, fire hydrants, and their accessories, ensuring rapid and effective initial fire suppression in the event of a fire. During routine use, fire hose reels are used to wind and store fire hoses within the box. In emergencies, operating fire hoses in confined spaces is not only cumbersome but also requires manually reconnecting the hose to the high-pressure valve inside the box after removal.
[0003] However, in actual use, because the internal space of the fire hose box is limited, most of the storage space is reserved for the fire hose reel, leaving very little space for people to operate and store. Moreover, it cannot actively release the fire hose, making its functionality very limited. Summary of the Invention
[0004] The technical problem that this invention aims to solve is that current fire hoses have limited storage space, are cumbersome to operate, and have limited functionality.
[0005] The technical solution adopted by the present invention to solve its technical problem is: a fire hose box with an active release mechanism, including a main box and a high-pressure fire water pipe connector installed inside the main box. The main box has openings on the front, sides and bottom. The openings on the front, sides and bottom of the main box are all hinged with flip doors. The flip doors on the sides and bottom of the main box are provided with inner limiting buckles for binding fire-fighting equipment. The main box is equipped with a pull-out front winding reel for winding fire hoses.
[0006] Each of the flip-top doors is equipped with a manual switch for opening and closing.
[0007] An emergency lighting lamp is installed on the upper surface of the main housing, and a built-in lighting lamp is installed on the inner top surface of the main housing.
[0008] The pull-out front winding disc includes a horizontal guide tube fixedly installed on the inner wall of the main box, a horizontal pull-out tube movably fitted on the outside of the horizontal guide tube, and an elastic limiting frame movably inserted into the opening position on the outside of the horizontal pull-out tube.
[0009] The inner arc-shaped surface of the horizontal guide tube is provided with an annular groove that cooperates with the elastic limiting frame.
[0010] The elastic limiting frame includes a fixed crossbar fixed inside the outer opening of the horizontal pull tube, limiting buckles elastically hinged to both ends of the inner side of the fixed crossbar, and a pressing control block elastically installed on the inner side of the fixed crossbar. The pressing control block drives the limiting buckles to flip and adjust by squeezing them.
[0011] The outer arc-shaped surface of the horizontal guide tube is provided with an interconnected internal storage groove and a strip-shaped guide groove, and an elastic torsion spring is movably fitted on the internal storage groove.
[0012] The internal storage slot is fitted with an elastic locking device around the elastic torsion spring.
[0013] The elastic locking device includes a locking seat fitted on the outside of the elastic torsion spring and a built-in locking block installed inside the locking seat. The inner wall of the internal receiving groove is provided with a lateral locking groove that cooperates with the built-in locking block.
[0014] The elastic torsion spring is equipped with a rotary damper inside.
[0015] The beneficial effects of this invention are: (1) A fire hose box with an active release mechanism of the present invention has a flip-up box door hinged at the openings on the front, sides and bottom of the main box, and an inner limit buckle for binding fire-fighting equipment is provided inside the flip-up box door, which can greatly increase the storage space inside the entire box and facilitate operation. (2) A pull-out front-mounted winding disc for winding fire hoses is installed inside the main box. The winding part can be moved to the outside by pulling it out, thereby increasing the operating space and making the operation more convenient. (3) The pull-out front winding disc is composed of a horizontal guide tube, a horizontal pull-out tube and an elastic limit frame. After being pulled out, the horizontal pull-out tube is controlled by an elastic torsion spring to rotate actively after being fully pulled out, thereby actively releasing the fire hose wrapped around its outer side. People can connect the joint while it is automatically released, so that the release and connection can be carried out simultaneously, improving efficiency. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.
[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0025] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The fire hose box shown includes a main box 1 and a high-pressure fire water pipe connector 2 installed inside the main box 1. The main box 1 has openings on the front, sides and bottom. The openings on the front, sides and bottom of the main box 1 are all hinged with flip doors 3. The flip doors 3 on the sides and bottom of the main box 1 are all provided with inner limit buckles 4 for binding fire-fighting equipment. The main box 1 is equipped with a pull-out front winding reel 5 for winding fire hoses.
[0026] To facilitate manual opening and closing, manual switches 6 are installed on the outer side of the flip-top door 3 for operation.
[0027] To provide illumination and warning for both the exterior and interior, a top-mounted emergency light 7 is installed on the upper surface of the main enclosure 1, and a built-in light 8 is installed on the inner top surface of the main enclosure 1.
[0028] To accommodate the pull-out design and elastic limit, the pull-out front winding tray 5 includes a horizontal guide tube 51 fixedly installed on the inner wall of the main housing 1, a horizontal pull-out tube 52 movably fitted on the outside of the horizontal guide tube 51, and an elastic limit frame 53 movably inserted into the opening position on the outside of the horizontal pull-out tube 52.
[0029] To facilitate the limiting action, an annular groove 511 that mates with the elastic limiting frame 53 is provided on the inner arc-shaped surface of the horizontal guide tube 51.
[0030] To facilitate manual control of the separation limit, the elastic limit frame 53 includes a fixed crossbar 531 fixed inside the outer opening of the horizontal pull tube 52, a limit buckle 532 elastically hinged to both ends of the inner side of the fixed crossbar 531, and a pressing control block 533 elastically installed inside the fixed crossbar 531. The pressing control block 533 drives the limit buckle 532 to flip and adjust by squeezing it.
[0031] People hold the fixed crossbar 531 with their fingers and then use their fingers to operate the pressing control block 533. By pressing the control block, the fixed crossbar 531 is squeezed and contracted, thereby squeezing the limiting buckles 532 at both ends, causing the limiting buckles 532 to flip and separate from the annular groove 511. At this time, the horizontal pull-out frame can be separated from the horizontal guide tube 51 and then pulled outward.
[0032] To facilitate lateral storage and flexible control, the outer arc-shaped surface of the horizontal guide tube 51 is provided with a connected internal storage groove 512 and a strip guide groove 513, and an elastic torsion spring 9 is movably fitted on the internal storage groove 512.
[0033] To facilitate automatic release, an elastic locking device 10 is fitted inside the internal storage slot 512, located around the elastic torsion spring 9.
[0034] To accommodate the elastic locking limit, the elastic locking device 10 includes a locking seat 101 fitted on the outside of the elastic torsion spring 9 and an internal locking block 102 installed inside the locking seat 101. The inner wall of the internal storage groove 512 is provided with a lateral locking groove 11 that cooperates with the internal locking block 102.
[0035] When the limiting block inside the horizontal guide tube 51 slides along the strip guide groove 513 into the internal storage groove 512, the limiting block will be inserted into the control groove on the locking seat 101, and at the same time squeeze the built-in locking block 102 located inside the control groove. By squeezing the built-in locking block 102, the outward protruding locking tongue of the built-in locking block 102 will be separated from the side locking groove 11. At this time, the elastic torsion spring 9 will drive the locking seat 101 to rotate along the internal storage groove 512, thereby automatically releasing the fire hose wrapped around the outside of the horizontal guide tube 51.
[0036] To reduce its release speed and improve safety, the elastic torsion spring 9 is equipped with a rotary damper.
[0037] The speed at which the elastic torsion spring 9 releases its kinetic energy can be effectively reduced by using a rotary damper, thereby avoiding danger caused by excessive elastic kinetic energy.
[0038] Work process The operator first opens the flip-top door 3 on the front of the main housing 1 using the manual switch 6, grasps the fixed crossbar 531 of the pull-out front winding disc 5, presses the press control block 533 to flip the limit buckle 532, separating it from the annular groove 511 of the horizontal guide tube 51, and pulls out the horizontal pull tube 52; fixes one end of the fire hose to the reserved interface of the horizontal pull tube 52, manually rotates the horizontal pull tube 52, and evenly winds the fire hose around the outside of the horizontal pull tube 52. During the winding process, the elastic torsion spring 9 is twisted and stored energy, and the built-in locking block 102 of the elastic locking device 10 automatically engages with the lateral locking groove 11 to complete the locking; after winding is completed, push the horizontal pull tube 52 to reset, and the limit buckle 532 of the elastic limit frame 53 resets under the elastic action and engages with the annular groove 511 to fix the horizontal pull tube 52.
[0039] Open the flip-top doors 3 on both sides and the bottom of the main body 1. Place the fire wrench, interface sealing gasket, spare connector and other auxiliary fire-fighting equipment into the inner limit buckles 4 inside the corresponding flip-top door 3. Secure the equipment with the elastic clamping force of the inner limit buckles 4 to prevent them from shaking and falling off. After confirming that all equipment is in place, close all flip-top doors 3 with the manual switch 6 to ensure that the doors are tightly fitted to the main body 1, so as to protect the internal fire hoses and equipment from dust, moisture and damage.
[0040] When the equipment is in the closed state, the top emergency light 7 and the built-in light 8 are in standby state, and are powered by the built-in power supply or the external power supply; the elastic locking device 10 is kept in the locked state, and the elastic torsion spring 9 stores enough energy to release the kinetic energy; all components of the pull-out front winding disc 5 are in the reset and fixed state, and the fire hose and the high-pressure fire water pipe joint 2 inside the main box 1 are in the pre-connected or convenient connection state, ready to be used at any time.
[0041] In the event of a fire, the operator quickly arrives at the equipment location and uses the manual switch 6 to sequentially or simultaneously open the flip doors 3 on the front, sides and bottom of the main housing 1. As the flip doors 3 open, the linkage switch is triggered, and the top emergency light 7 and the built-in light 8 immediately start, illuminating the external working area and the internal working area of the main housing 1 respectively, eliminating light obstruction.
[0042] The operator holds the fixed crossbar 531 and presses the control block 533 with their fingers. The control block 533 retracts into the fixed crossbar 531, and the two ends squeeze the limiting buckles 532 to make them rotate around the hinge point and disengage from the limit of the annular groove 511. At this time, the horizontal pull tube 52 is released from the fixed relationship with the horizontal guide tube 51. The operator smoothly pulls out the horizontal pull tube 52 along the axis of the horizontal guide tube 51. During the pulling process, the limiting block on the inner side of the horizontal pull tube 52 slides along the strip guide groove 513 to ensure the stability of the pulling direction.
[0043] When the horizontal pull-out tube 52 is pulled out to its limit position, its inner limiting block fully enters the internal storage groove 512, inserts into the control groove of the locking seat 101 and squeezes the built-in locking block 102. The locking tongue of the built-in locking block 102 exits from the lateral locking groove 11, and the elastic locking device 10 is unlocked. The elastic torsion spring 9 releases the stored elastic potential energy, drives the locking seat 101 to drive the horizontal pull-out tube 52 to rotate slowly along the axis of the horizontal guide tube 51 (the rotary damper 12 slows down the rotation speed). The fire hose wrapped around the outside of the horizontal pull-out tube 52 gradually loosens and hangs down naturally with the rotation, realizing active release.
[0044] While the fire hose is being actively released, the operator can simultaneously perform the connection operation—fully aligning the free end of the fire hose with the high-pressure fire water pipe connector 2 inside the main housing 1 and tightening it to seal, or directly using a pre-connected fire hose interface; after connection, open the high-pressure valve of the fire protection system, and the high-pressure water flow enters the fire hose through the high-pressure fire water pipe connector 2, and the operator holds the fire hose nozzle and aims it at the fire source to extinguish the fire; during the operation, the auxiliary tools inside the side and bottom flip-open housing doors 3 can be used at any time without having to search for them separately.
[0045] After the firefighting operation is completed, close the high-pressure valve and drain the residual water inside the fire hose; press the press control block 533 to flip the limit buckle 532, pull out the horizontal pull tube 52, manually rotate the horizontal pull tube 52 in the opposite direction, and rewrap the fire hose evenly around the outside of the horizontal pull tube 52. During the wrapping, the elastic torsion spring 9 twists and stores energy again until the fire hose is completely wrapped.
[0046] Push the horizontal pull tube 52 to reset along the axis of the horizontal guide tube 51. When the limit buckle 532 of the elastic limit frame 53 is aligned with the annular groove 511, press the control block 533 to reset under elastic action. The limit buckle 532 is engaged in the annular groove 511, thus fixing the horizontal pull tube 52 and the horizontal guide tube 51. At this time, the built-in locking block 102 of the elastic locking device 10 automatically engages in the lateral locking groove 11, locking the elastic torsion spring 9.
[0047] After cleaning and organizing the auxiliary fire-fighting equipment, put it back into the corresponding flip-top door 3 and secure it with the inner limit buckle 4. After confirming that there are no residual debris inside the main body 1 and that the fire hose and connectors are properly connected, close all the flip-top doors 3 in sequence using the manual switch 6 to ensure that the doors are locked in place. Finally, check whether the top emergency light 7 and the built-in light 8 are turned off. If they are in emergency start mode, manually reset them to restore the equipment to standby mode.
[0048] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
