Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a fire-extinguishing rack under a vehicle which can be quickly disassembled and assembled. Background Art

[0002] Cars are basically the most commonly used means of transportation at present. New energy vehicles are also widely popular. There is a risk of spontaneous combustion in cars. Both fuel vehicles and new energy vehicles have the risk of spontaneous combustion, which has caused certain safety hazards to many car users. As an important means of transportation in life, the safety performance and security system of cars are widely valued.

[0003] Spontaneous combustion of fuel vehicles is generally caused by aging or damage of internal circuits, which leads to short circuit and spontaneous combustion, and then ignites the interior decorations and fuel of the vehicle. There are also spontaneous combustion phenomena caused by engine failure. This type of fuel and car interior fire usually occurs above the vehicle chassis, and the fire point is outside the vehicle. It can be extinguished by directly spraying water from the outside or spraying directly with a fire extinguisher.

[0004] New energy vehicles are different. Once a new energy vehicle catches fire, the open flame on the surface is easy to deal with. However, the most important fire point for new energy vehicles is the battery under the chassis. This location is hidden and difficult to reach, which makes it difficult to extinguish the fire. Moreover, the battery is prone to explosion or reignition, causing a major safety hazard at the scene. Generally, even after the fire of a new energy vehicle is extinguished, as long as it does not affect traffic and the safety of surrounding personnel, it needs to be left alone for a long time, sometimes even for several hours, until it is ensured that the vehicle is completely burned out or the battery is completely burned out before subsequent processing of the vehicle will be carried out. This is a helpless move.

[0005] Currently, there are devices that can effectively cool down and extinguish fires at the bottom of vehicles, but they are all fixed devices and are large in size, generally similar to the battery paving area at the bottom of the vehicle. Even fire trucks cannot be loaded with them. They can only be tied to fire trucks when it is known that a vehicle is on fire, which brings inconvenience to firefighting operations and police dispatch.

[0006] Based on this, the utility model designs a vehicle bottom fire extinguishing rack that can be quickly disassembled and assembled to solve the above problems. Utility Model Content

In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0051] In a specific embodiment of the technical solution of the present utility model:

[0052] It includes a connecting frame 1, a docking frame 11, a water spray pipe 2, a docking female connector 3, a limiting claw seat 4 and a plug male connector 5;

[0053] The connecting frame 1 and the docking frame 11 are both closed straight pipes; the water spray pipe 2 is a straight pipe with both ends open;

[0054] Both the connecting frame 1 and the docking frame 11 have mounting holes 13 on their inner sides. A water pipe connector 12 is provided on the outer side of the connecting frame 1, through which the connecting frame 1 connects to an external water pipe. This connector is a fire hose connector and includes a filter screen. This connector can be easily connected to a fire hydrant or a fire truck's fire hose.

[0056] Multiple water spray pipes 2 are installed between the connecting frame 1 and the docking frame 11. The connecting frame 1, docking frame 11, and multiple water spray pipes 2 are spliced ​​together in the same plane to form an integral frame structure. The connecting frame 1, docking frame 11, and multiple water spray pipes 2 are internally sealed and connected to form an integrated pipeline. Each water spray pipe 2 is arranged parallel to each other, and the connecting frame 1 and docking frame 11 are perpendicular to the water spray pipes 2.

[0057] The water spray pipes 2 are evenly spaced, and the plurality of nozzles 21 are also evenly spaced. The nozzles 21 are fire sprinklers.

[0058] The female butt joint 3 is a round pipe joint with threads at both ends. The fixed end of the female butt joint 3 can be detachably locked on the mounting hole 13, and the splicing end of the female butt joint 3 is locked with the fixed ring 31;

[0059] The fixed ring 31 is a circular buckle cover structure, which is screwed onto the female connector 3. A circular hole is formed on the fixed ring 31, and the circular hole penetrates both the inner and outer sides of the fixed ring 31.

[0060] The limiting claw seat 4 is a sheet-shaped circular ring, and three limiting blocks 43 are protruding outward on one side of the limiting claw seat 4. The limiting blocks 43 are arc-shaped sheet structures. The three limiting blocks 43 are perpendicular to the plane where the limiting claw seat 4 is located, and the three limiting blocks 43 are evenly spaced and arranged in a ring around the edge of the inner circle hole of the limiting claw seat 4;

[0061] The limiting claw seat 4 is also provided with a spring claw 41, which is an annular sheet structure. A spring claw 41 is provided in the gap between each limiting block 43, and a spring sheet 42 is locked on the outer wall of each spring claw 41;

[0062] The limiting claw seat 4 is stably mounted between the mating female connector 3 and the fixed ring 31. Each spring claw 41 is retractably pressed against the annular inner wall of the fixed ring 31 via a spring plate 42, extending from the interior of the inner hole of the limiting claw seat 4. The three spring claws 41 are arranged in a circular ring shape within the same plane, and the three spring claws 41 are disconnected from each other, not contacting each other. The diameter of the ring formed by the three spring claws 41 is smaller than the inner hole diameter of the limiting claw seat 4. The limiting claw seat 4, the three spring claws 41, and the three spring plates 42 form an integrated structure that is installed together within the mating female connector 3 to form an integrated mounting structure for quick, plug-in mounting of the male connector 5.

[0063] The fixed end of the plug-in male connector 5 is provided with a thread on the outside. The plug-in end of the plug-in male connector 5 is a retaining ring 52. The retaining ring 52 is an outwardly protruding annular step. The diameter of the retaining ring 52 is larger than the outer diameter of the plug-in male connector 5.

[0064] The three spring claws 41 can be detachably clamped on the outer wall of the male connector 5, and the spring claws 41 are clamped on the outer end surface of the locking ring 52;

[0065] A sealing ring 32 is also provided inside the docking female connector 3, and the sealing ring 32 is tightly fitted on the outside of the splicing end of the positioning ring 52; an annular step surface is also provided on the splicing end of the docking female connector 3.

[0066] The locking ring 52 is clamped and pressed against the step surface of the splicing end of the docking female connector 3 via the spring claw 41 , and the inner hole of the docking female connector 3 is sealed and communicated with the inner hole of the locking ring 52 .

[0067] The plug-in male connector 5 is a round pipe connector. A plug-in male connector 5 is locked at each end of the water spray pipe 2. The plug-in male connector 5 can be detachably plugged into the circular hole of the fixed ring 31.

[0068] The connecting frame 1 is sealed and plugged with the water spray pipe 2 through the connecting female connector 3 and the plugging male connector 5, and the connecting frame 11 is also sealed and plugged with the water spray pipe 2 in a detachable manner through the connecting female connector 3 and the plugging male connector 5.

[0069] A pressure ring 51 is also sleeved on the outside of the male connector 5. The pressure ring 51 is a circular ring, and the inner diameter of the pressure ring 51 is larger than the outer diameter of the male connector 5.

[0070] The outer diameter of the male connector 5 is smaller than the diameter of the circular hole of the fixed ring 31; the diameter of the pressure ring 51 is smaller than the diameter of the fixed ring 31, and there is a clearance fit between the male connector 5, the pressure ring 51, and the fixed ring 31. During installation, only the female connector 1 and the male connector 5 need to be plugged together to seal the connection, achieving quick installation. The pressure ring 51 is slidably mounted on the outer wall of the male connector 5. During removal, only the pressure ring 51 needs to be pushed into the fixed ring, squeezing and opening the spring claws 41, so that the spring claws 41 quickly release the retaining ring 52, achieving the purpose of quick removal.

[0071] A plurality of positioning pieces 22 are fastened to the top of the docking frame 11 by bolts, and each positioning piece 22 is located directly above a mounting hole 13;

[0072] The positioning piece 22 is a sheet-like structure, and a positioning groove 23 is provided at one end of the positioning piece 22. The positioning groove 23 is a U-shaped groove with an outer opening.

[0073] The positioning piece 22 is also provided with an avoidance hole 24, which is clamped on the raised arc on the top of the fixed ring 31;

[0074] Each positioning piece 22 is stably mounted on the outermost nozzle 21 of a water spray pipe 2 through a positioning groove 23; because the positioning groove 23 is a U-shaped groove and opens toward one side of the water spray pipe 2, Figure 3As shown, the nozzle 21 can be drawn downward or along the opening direction of the positioning groove 23, but the nozzle 21 cannot be rotated after being stuck in the positioning groove 23, ensuring that the nozzle 21 always remains facing upward.

[0075] When the present invention is in use, the entire structure needs to be spliced, that is, the connecting frame 1, the docking frame 11 and the multiple water spray pipes 2 need to be spliced ​​into a complete frame, and the internal pipes are interconnected, so that the water from the water pipe joint 12 is transported through the connecting frame 1, the docking frame 11 and the multiple water spray pipes 2, and finally sprayed upward by the nozzle 21.

[0076] This device has two states, the split storage state is as follows Figure 2 As shown, the female connector 3 is locked to the connecting frame 1 and the docking frame 11, maintaining a stable connection and requiring replacement only when damaged. The water pipe 2 is in a separate, separate state. At this time, the splicing male connector 5 is screwed onto the water pipe 2. The splicing end of the splicing male connector 5 is provided with a larger diameter locking ring 52 for engaging and docking with the spring claw 41. A pressure ring 51 is also slidably mounted on the outside of the splicing male connector 5 to squeeze the spring claw 41 to force it to release the locking ring 52.

[0077] The mounting holes 13 of the connecting frame 1 and the docking frame 11 are both threadedly mounted with docking female heads 3, and each docking female head 3 is also threadedly locked with a fixed ring 31. The inner hole of the docking female head 3 has a splicing end face, which is a step surface. Figure 10 As shown, a sealing ring 32 is installed on this end face, and the final plug-in male connector 5 is also pressed against this end face to achieve a sealing effect.

[0078] The inner end surface of the docking female connector 3 is designed to ensure that the position of the sealing ring 32 remains fixed, and it can rotate axially as long as it does not slide along with the insertion of the plug-in male connector 5.

[0079] In addition, a limiting claw seat 4 is installed at the gap between the fixed ring 31 and the docking female head 3. The spring claw 41 and the spring sheet 42 are locked into an integral force-bearing structure by bolts, and the overall structure of the spring claw 41 and the spring sheet 42 is installed at the gap between the limiting block 43 of the limiting claw seat 4. The spring sheet 42 is elastically pressed against the inner wall of the external fixed ring 31, and the inner arc surface of the spring claw 41 extends toward the axial direction of the limiting block 43 to clamp the positioning ring platform 52.

[0080] The splicing status of this device is as follows Figure 1 As shown, when the water spray pipe 2 needs to be disassembled, the pressure ring 51 is squeezed toward the locking ring platform 52, and the pressure ring 51 is squeezed into the gap between the locking ring platform 52 and the circular hole of the fixed ring 31, and the pressure ring 51 squeezes the spring claw 41 to bounce it open, and the spliced ​​end of the released spring claw 41 is a slope to relax it.

[0081] The splicing end of the spring claw 41 is a bevel, such as Figure 10 As shown, the splicing end face of the spring claw 41, that is, the right side has a larger diameter, and the inner side of the spring claw 41, that is, the splicing end face with the docking female head 3, that is, the side where the spring claw 41 and the docking female head 3 are in contact with each other is a flat surface, and the diameter here is smaller than the diameter of the splicing end of the spring claw 41, making it easier for the locking ring 52 to slide in along the outer inclined surface of the spring claw 41, and when the locking ring 52 is disengaged outward, the straight surface on the inner side of the spring claw 41 will be clamped with the locking ring 52, limiting the locking ring 52 from escaping outward, thereby achieving the purpose of effective clamping.

[0082] When there is no external force, the spring claw 41 is pressed toward the axis under the action of the spring sheet 42, and the spring claw 41 is blocked at the inner circular hole of the fixed ring 31;

[0083] When subjected to outward extrusion force, the spring claw 41 will press the spring sheet 42 to fit the inner wall of the fixed ring 31, so that the spring claw 41 retracts outward and no longer blocks the inner hole of the fixed ring 31, so that the fixed ring 31 remains unobstructed.

[0084] The pressing ring 51 and the locking ring platform 52 both press the spring claws 41 from outside to inside, causing the spring claws 41 to retract outward, thereby keeping the fixed ring 31 unobstructed.

[0085] The male connector 5 is disassembled by compressing the spring claw 41 with the pressure ring 51. The spring claw 41 retracts to the outer ring of the fixed ring 31. The spring claw 41 no longer blocks the locking ring 52. The joint end surface of the locking ring 52 and the pressure ring 51 forms abutment inside the circular hole of the fixed ring 31. The locking ring 52 and the pressure ring 51 are pulled out of the fixed ring 31 together, thereby achieving the purpose of separating the female connector 3 from the male connector 5. This structure ensures a firm connection during insertion and easy operation during removal.

[0086] The splicing end of the device refers to the butt joint end of the docking female connector 3 and the plug-in male connector 5, the inner side of the single circular tube structure refers to the axis, and the outer side refers to the outer wall; the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply 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 to the present invention.

[0087] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included within the scope of protection of the claims of the present invention.
