Description

Technical Field

[0001] This application relates to the field of fire-fighting equipment technology, and in particular to a portable fire extinguishing bomb. Background Technology

[0002] A fire is a combustion that gets out of control in time or space. It is usually caused by electrical faults, improper use of open flames, smoking, improper storage of flammable materials, or natural disasters (such as lightning strikes). Fires can easily cause serious casualties and property damage, and may even have long-term environmental and social impacts. For places with high population density or large amounts of stored objects, fire prevention efforts should be strengthened to prevent fires from occurring in the first place. Currently, there are various fire extinguishing tools available on the market, such as fire extinguishers (e.g., dry powder fire extinguishers, carbon dioxide fire extinguishers, and foam fire extinguishers), fire hydrants, fire sand, fire blankets, and fire extinguishing bombs. Among these, fire extinguishing bombs have excellent characteristics such as ease of operation and rapid fire suppression, and are more suitable for initial fire suppression or for fires in hard-to-reach areas, making them widely used in various types of fires.

[0003] In related technologies, when using fire extinguishing bombs for fire suppression, the bombs are thrown into the flames, and the extinguishing material inside is released through an ignition or triggering mechanism. The released extinguishing material undergoes a negative catalytic reaction in the flames, thereby suppressing combustion and extinguishing the fire. However, fire extinguishing bombs are usually placed in designated locations for storing fire-fighting equipment. When the fire occurs far from these locations, such as in confined spaces, hidden corners, or areas with low foot traffic (e.g., server rooms, electrical equipment rooms, uninterruptible power supply rooms / power plants), retrieving the fire extinguishing bombs is inconvenient and time-consuming, which seriously affects fire rescue efforts. Utility Model Content

[0004] This application provides a portable fire extinguishing bomb, which aims to solve the problem in related technologies where it is inconvenient to retrieve fire extinguishing bombs when the fire site is far from the location where the fire extinguishing bombs are stored.

[0005] To address the aforementioned drawbacks of related technologies, this application provides a portable fire extinguishing grenade. This portable fire extinguishing grenade includes a fixing block, a limiting member, and a fire extinguishing grenade body. The fire extinguishing grenade body contains fire extinguishing material. The limiting member includes a main limiting structure and a secondary limiting structure. The fixing block is used to mount on a wall and has a limiting hole. The secondary limiting structure is disposed within the limiting hole, and the main limiting structure is disposed on the outer wall of the fire extinguishing grenade body. Specifically, the main limiting structure is used to: insert into the limiting hole and receive a pressing force that causes it to move into the limiting hole, thereby engaging with the secondary limiting structure and confining itself within the limiting hole, thus fixing the fire extinguishing grenade body relative to the fixing block; or, when engaged with the secondary limiting structure, first receive a pressing force, then receive a pulling force that causes it to move out of the limiting hole, thereby releasing itself from the limiting hole and separating the fire extinguishing grenade body from the fixing block.

[0006] In some implementation schemes, the portable fire extinguishing bomb also includes a fixing component set on the outer wall of the fire extinguishing bomb body, two limiting components, the main limiting structures of the two limiting components are respectively set at opposite ends of the fixing component, two limiting holes are respectively opened at opposite ends of the fixing block, and the secondary limiting structures of the two limiting components are respectively set in the two limiting holes.

[0007] In some implementation schemes, the main limiting structure includes a limiting rod, a fixed ring, a sliding ring, and a limiting head. One end of the limiting rod is set on the fixing member, and the limiting head is set on the other end of the limiting rod. The fixed ring is sleeved on the limiting rod, and the sliding ring is sleeved on the limiting rod and located between the fixed ring and the limiting head. The sliding ring slides with the limiting rod. The side of the sliding ring away from the limiting head has a first inclined surface that slopes towards the limiting rod. When the sliding ring slides along the limiting rod to abut against the limiting head, the first inclined surface connects to the side wall of the limiting head. A first sliding hole is formed in the wall of the limiting hole, which is recessed into the fixing block. The limiting structure includes a limiting block, a first sliding rod, and a first spring. One end of the first sliding rod is inserted into the first sliding hole and slides with it. The limiting block is set on the other end of the first sliding rod. The first spring is sleeved on the first sliding rod. One end of the first spring is set in the first sliding hole, and the other end abuts against the limiting block. The end of the limiting block away from the first sliding rod has a second inclined surface that slopes towards itself.

[0008] Specifically, the second inclined surface is used for: during the engagement of the main limiting structure and the secondary limiting structure, abutting against the limiting head, and under the action of pressing force, causing the limiting block to pass over the limiting head, with the limiting block abutting against the limiting rod and located between the limiting head and the sliding ring; or, during the disengagement of the main limiting structure and the secondary limiting structure, abutting against the side of the sliding ring near the limiting head, and under the action of pressing force, first causing the sliding ring to slide to abut against the fixed ring, and then causing the limiting block to pass over the sliding ring, with the limiting block abutting against the limiting rod and located between the sliding ring and the fixed ring. The first inclined surface is used for: during the disengagement of the main limiting structure and the secondary limiting structure, after the limiting block abuts against the limiting rod and is located between the sliding ring and the fixed ring, abutting against the lower side of the limiting block, and under the action of pulling force, first causing the sliding ring to slide to abut against the limiting head, and then causing the limiting block to pass over the sliding ring and the limiting head in sequence.

[0009] In some implementation schemes, the limiting structure also includes a limiting ring, which is sleeved on the first sliding rod and located in the first sliding hole near the opening, for abutting the end of the first spring near the limiting head; the outer wall of the limiting ring is provided with two opposing first sliding blocks, and the hole wall of the first sliding hole is provided with two opposing first sliding grooves extending along its own axis, and the two first sliding blocks are respectively located in the two first sliding grooves and slide in cooperation with the two first sliding grooves respectively.

[0010] In some implementations, the sliding ring includes a middle ring and two side rings, which are respectively disposed on opposite sides of the middle ring. Both side rings have a first inclined surface that is inclined toward the limiting rod. The limiting head has an annular groove on the side near the sliding ring, which is used to accommodate the side ring near the limiting head, or to accommodate the middle ring and the side ring near the limiting head, when the sliding ring abuts against the limiting head.

[0011] In some implementations, the outer surface of the limit head is an arc surface.

[0012] In some implementations, the fixing component includes a connecting rod, two fixing parts, and two extension parts. The two fixing parts are disposed opposite to each other on the outer wall of the fire extinguishing projectile. One end of each of the two extension parts is disposed on one of the two fixing parts. The connecting rod connects the other ends of the two extension parts. The main limiting structures of the two limiting components are disposed on the two extension parts. Further, the fixing block includes a base and two partitions. The base is used to be mounted on a wall. Two limiting holes are respectively opened at opposite ends of the base. One end of each of the two partitions is disposed opposite to each other and spaced apart on the base, and both are located between the two limiting holes. The other ends of both partitions are suspended. The connecting rod is used to accommodate in the gap between the two partitions when the main limiting structure is inserted into the corresponding limiting hole and engages with the corresponding secondary limiting structure.

[0013] In some implementations, the portable fire extinguishing bomb also includes an elastic element set on the base and located between two partitions, used to: be compressed by the connecting rod when the main limiting structure is inserted into the corresponding limiting hole and engaged with the corresponding secondary limiting structure; or, use its own elasticity as a pulling force during the process of releasing the engagement between the main limiting structure and the secondary limiting structure.

[0014] In some implementations, the elastic component includes a support plate, a second sliding rod, a second spring, and two second sliders. The support plate is located in the gap between the two partitions. The two second sliders are respectively located on opposite sides of the support plate. The inner sides of the two partitions are provided with second sliding grooves. The two second sliders are located in the two second sliding grooves and are slidably engaged with the two second sliding grooves. The base is provided with a second sliding hole located between the two partitions. One end of the second sliding rod is located on the side of the support plate near the base, and the other end of the second sliding rod is inserted into the second sliding hole and is slidably engaged with the second sliding hole. The second spring is sleeved on the second sliding rod, with one end of the second spring located in the second sliding hole and the other end abutting against the support plate.

[0015] In some implementations, the portable fire extinguishing bomb also includes a handle located on the outer wall of the fire extinguishing bomb body, with the handle situated at the top of the fire extinguishing bomb body.

[0016] The portable fire extinguishing bomb provided in this application consists of a fixing block, a limiting member, and a fire extinguishing bomb body. The fixing block is used to install on a wall and has a limiting hole. The limiting member includes a main limiting structure and a secondary limiting structure. The main limiting structure is installed on the outer wall of the fire extinguishing bomb body, and the secondary limiting structure is installed in the limiting hole. The main limiting structure is inserted into the limiting hole, and a pressing force is applied to the main limiting structure to move it into the limiting hole, thereby engaging the main limiting structure with the secondary limiting structure in the limiting hole. At this time, the main limiting structure is restricted within the limiting hole, and the fire extinguishing bomb body is relatively fixed to the fixing block. When the main limiting structure and the secondary limiting structure are engaged, a pressing force is first applied to the main limiting structure, and then a pulling force is applied to the main limiting structure to move it out of the limiting hole, thereby releasing the engagement between the main limiting structure and the secondary limiting structure. At this time, the main limiting structure disengages from the limiting hole, and the fire extinguishing bomb body separates from the fixing block. Therefore, this application demonstrates that the fire extinguishing bomb can be easily fixed to the wall by applying pressure to the main limiting structure, and can be easily removed from the wall by applying pressure and pulling force to the main limiting structure sequentially. Furthermore, the fire extinguishing bomb can be placed on walls in any location, such as in confined spaces, hidden corners, or areas with low foot traffic. This greatly improves the ease of use of the fire extinguishing bomb, and makes it easier to retrieve the fire extinguishing bomb in the event of a fire in these locations. The entire process of retrieving the fire extinguishing bomb is also shorter, which is highly beneficial for fire rescue. Attached Figure Description

Detailed Implementation

[0025] In related technologies, fire extinguishing bombs are usually placed in designated locations for storing fire-fighting equipment. When a fire occurs far from these locations, such as in confined spaces, hidden corners, or areas with low foot traffic (e.g., server rooms, electrical equipment rooms, uninterruptible power supply rooms / power plants), retrieving the fire extinguishing bombs is inconvenient and time-consuming, severely hindering fire rescue efforts. Therefore, this application proposes a portable fire extinguishing bomb in the following embodiments. This portable fire extinguishing bomb can be placed on a wall in any location, such as a wall near a confined space, hidden corner, or area with low foot traffic. Its small size allows for easy and quick detachment from walls, effectively solving the aforementioned drawbacks of related technologies.

[0026] To make the objectives, technical solutions, and advantages of this application more apparent and understandable, this application will be clearly and completely described below in conjunction with its embodiments and corresponding drawings. Throughout, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. It should be understood that the embodiments of this application described below are only for explaining this application and are not intended to limit this application. That is, all other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. Furthermore, the technical features involved in the various embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0027] Please see Figure 1 , Figure 2 as well as Figure 3 , Figure 1 This is a structural diagram of a portable fire extinguishing bomb from one perspective. Figure 2 This is a structural diagram of a portable fire extinguishing bomb from another perspective. Figure 3This is a structural schematic diagram of a portable fire extinguishing bomb when the fixed block is partially concealed. This embodiment provides a portable fire extinguishing bomb, which includes a fixed block 200, a limiting member 400, and a fire extinguishing bomb body 100. The fire extinguishing bomb body 100 contains fire extinguishing material. The limiting member 400 includes a main limiting structure 410 and a secondary limiting structure 420. The fixed block 200 is used to be installed on a wall and has a limiting hole (not shown). The main limiting structure 410 is located on the outer wall of the fire extinguishing bomb body 100, and the secondary limiting structure 420 is located within the limiting hole. Preferably, the triggering mechanism of the fire extinguishing projectile 100 is either activated by a wire and an open flame, or activated by a pull wire and manually. The fire extinguishing material inside the fire extinguishing projectile 100 is an aerosol powder (composed of very fine solid particles suspended in a gas). The aerosol powder can undergo a negative catalytic reaction at a temperature greater than or equal to 270 degrees Celsius. When a negative catalytic reaction occurs, the aerosol powder becomes 70% gas and 30% fixed powder. Combustion can be suppressed by these 70% gas and 30% fixed powder, thus achieving fire extinguishing.

[0028] Specifically, the main limiting structure 410 is used to: insert into the limiting hole and receive the pressing force that moves itself into the limiting hole, so as to engage with the secondary limiting structure 420, thereby restricting itself within the limiting hole and fixing the fire extinguishing projectile 100 and the fixing block 200 relative to each other; or, when it is engaged with the secondary limiting structure 420, it first receives the pressing force, and then receives the pulling force that moves itself out of the limiting hole, so as to release itself from the engagement with the secondary limiting structure 420, thereby disengaging itself from the limiting hole and separating the fire extinguishing projectile 100 from the fixing block 200. In other words, the main limiting structure 410 is inserted into the limiting hole, and a pressing force is applied to the main limiting structure 410 to move it into the limiting hole, so as to engage the main limiting structure 410 with the secondary limiting structure 420 in the limiting hole. At this time, the main limiting structure 410 is restricted in the limiting hole, and the fire extinguishing projectile 100 and the fixing block 200 are relatively fixed. When the main limiting structure 410 and the secondary limiting structure 420 are engaged, a pressing force is first applied to the main limiting structure 410, and then a pulling force is applied to the main limiting structure 410 to move it out of the limiting hole, so as to release the engagement between the main limiting structure 410 and the secondary limiting structure 420. At this time, the main limiting structure 410 can be disengaged from the limiting hole, and the fire extinguishing projectile 100 can be separated from the fixing block 200.

[0029] In this embodiment, the number of limiting members 400 may include one, two, or more. When there are several limiting members 400, they should be disposed at different positions on the outer wall of the fire extinguishing projectile 100. Regardless of the number of limiting members 400, the number of limiting holes on the fixing block 200 is consistent with the number of limiting members 400, and each limiting hole corresponds one-to-one with a specific limiting member 400. Furthermore, it should be noted that the number of limiting members 400 and limiting holes, the distribution of limiting members 400 on the fire extinguishing projectile 100, and the distribution of limiting holes on the fixing block 200 can all be set according to actual needs, and this application does not impose a unique limitation on this. Preferably, there are two limiting members 400 and two limiting holes, with the two limiting members 400 disposed opposite each other on the outer wall of the fire extinguishing projectile 100, and the two limiting holes respectively disposed at opposite ends of the fixing block 200.

[0030] As can be seen from the above, in this embodiment, the fire extinguishing projectile 100 can be easily fixed to the fixing block 200 (equivalent to a wall) by applying pressure to the main limiting structure 410, and the fire extinguishing projectile 100 can be easily removed from the fixing block 200 (equivalent to a wall) by applying pressure and pulling force to the main limiting structure 410 in sequence. Furthermore, the fire extinguishing projectile 100 can be placed on the wall in any location, such as on the wall near a small, hidden corner or a place with low traffic. This can greatly improve the convenience of using the fire extinguishing projectile 100. Especially when a fire occurs in these locations, it will be more convenient to retrieve the fire extinguishing projectile 100, and the entire process of retrieving the fire extinguishing projectile 100 will take less time, which is very beneficial for fire rescue.

[0031] In some embodiments, still refer to Figures 1 to 3 In addition to the structure described above, the portable fire extinguishing grenade also includes a fixing member 300 disposed on the outer wall of the fire extinguishing grenade body 100. When both the limiting member 400 and the limiting hole include two, the two main limiting structures 410 are respectively disposed at opposite ends of the fixing member 300, and the two secondary limiting structures 420 are respectively disposed in the two limiting holes. As one embodiment, the fixing member 300 includes a connecting rod 330, two fixing parts 310, and two extension parts 320. The two fixing parts 310 are disposed opposite each other on the outer wall of the fire extinguishing grenade body 100, one end of each of the two extension parts 320 is disposed on the two fixing parts 310, the connecting rod 330 connects the other ends of the two extension parts 320, and the two main limiting structures 410 are respectively disposed on the two extension parts 320. Of course, in other embodiments, the fixing parts 310 or the extension parts 320 may be omitted. The specific configuration can be made according to actual needs, and this application does not limit it in this way.

[0032] Furthermore, the fixing block 200 includes a base 210 and two partitions 220. The base 210 is used to be installed on the wall. Two limiting holes are respectively opened at opposite ends of the base 210. One end of the two partitions 220 is arranged opposite to each other and spaced apart on the base 210, and both are located between the two limiting holes. The other ends of the two partitions 220 are suspended. The connecting rod 330 is used to be accommodated in the gap 221 between the two partitions 220 when the main limiting structure 410 is inserted into the corresponding limiting hole and engaged with the corresponding secondary limiting structure 420. Understandably, during the process of inserting the main limiting structure 410 into the corresponding limiting hole, the connecting rod 330 will enter the gap 221 between the two partitions 220. As the main limiting structure 410 continues to penetrate into the limiting hole, when the main limiting structure 410 engages with the corresponding secondary limiting structure 420, the connecting rod 330 will be completely inserted into the gap 221 to restrict the connecting rod 330 between the two partitions 220.

[0033] In some embodiments, please combine Figure 4 , Figure 4 This is a schematic diagram of the limiting component. The main limiting structure 410 includes a limiting rod 411, a fixing ring 413, a sliding ring 414, and a limiting head 412. One end of the limiting rod 411 is mounted on the fixing component 300, and the limiting head 412 is mounted on the other end of the limiting rod 411. The fixing ring 413 is sleeved on the limiting rod 411, and the sliding ring 414 is sleeved on the limiting rod 411 and located between the fixing ring 413 and the limiting head 412. The sliding ring 414 slides in cooperation with the limiting rod 411. The side of the sliding ring 414 away from the limiting head 412 has a first inclined surface 4141 that is inclined towards the limiting rod 411. When the sliding ring 414 slides along the limiting rod 411 to abut against the limiting head 412, the first inclined surface 4141 connects with the side wall of the limiting head 412. Furthermore, a first sliding hole (not shown) recessed into the fixing block 200 is formed on the wall of the limiting hole. The limiting structure 420 includes a limiting block 422, a first sliding rod 421 and a first spring 423. One end of the first sliding rod 421 is inserted into the first sliding hole and slides in cooperation with the first sliding hole. The limiting block 422 is disposed on the other end of the first sliding rod 421. The first spring 423 is sleeved on the first sliding rod 421. One end of the first spring 423 is disposed in the first sliding hole and the other end abuts against the limiting block 422. The end of the limiting block 422 away from the first sliding rod 421 has a second inclined surface 4221 that is inclined towards itself.

[0034] Specifically, the second inclined surface 4221 is used to: abut against the limiting head 412 during the engagement of the main limiting structure 410 and the secondary limiting structure 420, and under the action of pressing pressure, cause the limiting block 422 to pass over the limiting head 412, with the limiting block 422 abutting against the limiting rod 411 and located between the limiting head 412 and the sliding ring 414; or, during the disengagement of the engagement of the main limiting structure 410 and the secondary limiting structure 420, abut against the side of the sliding ring 414 near the limiting head 412, and under the action of pressing pressure, first cause the sliding ring 414 to slide to abut against the fixed ring 413, and then cause the limiting block 422 to pass over the sliding ring 414, with the limiting block 422 abutting against the limiting rod 411 and located between the sliding ring 414 and the fixed ring 413. The first inclined surface 4141 is used to: during the process of releasing the engagement between the main limiting structure 410 and the secondary limiting structure 420, when the limiting block 422 abuts against the limiting rod 411 and is located between the sliding ring 414 and the fixed ring 413, it abuts against the lower side of the limiting block 422, and under the action of the pulling force, the sliding ring 414 first slides to abut against the limiting head 412, and then the limiting block 422 passes over the sliding ring 414 and the limiting head 412 in sequence.

[0035] Understandably, the process of engaging the main limiting structure 410 with the corresponding secondary limiting structure 420 is as follows: the limiting rod 411 is inserted into the corresponding limiting hole, and a pressing force is applied to the limiting rod 411, causing the limiting rod 411 and the limiting head 412 to move into the limiting hole; when the movement reaches the point where the limiting head 412 abuts against the second inclined surface 4221 of the limiting block 422, the pressing force is continued to be applied to the limiting rod 411, and the limiting head 412 continues to move into the limiting hole, while also sliding along the second inclined surface 4221 of the limiting block 422. The limiting block 422 will push the first sliding rod 421 to slide into the first sliding hole and compress the first spring 423; As the limiting head 412 continues to move into the limiting hole, the limiting block 422 will eventually pass over the limiting head 412. The limiting block 422 will also abut against the limiting rod 411 under the elastic force of the first spring 423 and be located between the limiting head 412 and the sliding ring 414. If a pulling force is applied to the limiting rod 411 at this time, the upper side of the limiting head 412 will abut against the lower side of the limiting block 422. That is, the limiting block 422 blocks the limiting head 412 from moving away from the limiting hole, thereby realizing the engagement between the main limiting structure 410 and the secondary limiting structure 420. In other words, the main limiting structure 410 will be restricted within the limiting hole.

[0036] The process of releasing the engagement between the main limiting structure 410 and the secondary limiting structure 420 includes a first process and a second process performed sequentially. The first process is as follows: a pressing force is applied to the limiting rod 411, causing the limiting rod 411 and the limiting head 412 to move into the limiting hole; when the movement reaches the point where the second inclined surface 4221 of the limiting block 422 abuts against the side of the sliding ring 414 near the limiting head 412, the pressing force is continued to be applied to the limiting rod 411, causing the limiting rod 411 to continue moving into the limiting hole, while the limiting block 422 pushes the sliding ring 414 to slide towards the fixed ring 413; when the sliding ring 414 slides to the point where it is in contact with the fixed ring 413, the pressing force is continued to be applied to the limiting rod 411, causing the limiting rod 411 to continue moving into the limiting hole, while the limiting block 422 pushes the sliding ring 414 to slide towards the fixed ring 413; when the sliding ring 414 slides to the point where it is in contact with the fixed ring 413, the pressing force is continued to be applied to the limiting rod 411. When the three phases are in contact, the pressing force continues to be applied to the limiting rod 411, and the limiting rod 411 continues to move into the limiting hole. At the same time, the sliding ring 414 is blocked by the fixed ring 413 and will slide along the second inclined surface 4221 of the limiting block 422. The limiting block 422 will push the first sliding rod 421 to slide into the first sliding hole and compress the first spring 423. As the limiting rod 411 continues to move into the limiting hole, the limiting block 422 will eventually pass over the sliding ring 414. The limiting block 422 will also abut against the limiting rod 411 under the elastic force of the first spring 423 and be located between the sliding ring 414 and the fixed ring 413. The second process is as follows: A pulling force is applied to the limiting rod 411, causing the limiting rod 411 and the limiting head 412 to move outward from the limiting hole. The first inclined surface 4141 of the sliding ring 414, away from the limiting head 412, abuts against the lower side of the limiting block 422. As the limiting rod 411 moves outward from the limiting hole, the sliding ring 414, blocked by the limiting block 422, slides towards the limiting head 412. When the sliding ring 414 slides to abut against the limiting head 412, the first inclined surface 4141 of the sliding ring 414, away from the limiting head 412, connects with the side wall of the limiting head 412. Afterward, the pulling force continues... When the positioning rod 411 applies a pulling force, the lower side of the limiting block 422 will slide along the first inclined surface 4141 of the sliding ring 414 away from the limiting head 412 to the side wall of the limiting head 412. As the limiting rod 411 continues to move out of the limiting hole, the limiting block 422 will eventually slide out of the side wall of the limiting head 412, that is, the limiting block 422 completely passes over the sliding ring 414 and the limiting head 412. At this time, the engagement between the main limiting structure 410 and the secondary limiting structure 420 is released, that is, the main limiting structure 410 can be disengaged from the limiting hole, and the fire extinguishing projectile 100 can also be separated from the fixing block 200.

[0037] In one embodiment, the limiting structure 420, in addition to the structure described above, also includes a limiting ring 424. The limiting ring 424 is sleeved on the first sliding rod 421 and located in the first sliding hole near the opening, for abutting the end of the first spring 423 near the limiting head 412. Two opposing first sliders 425 are provided on the outer wall of the limiting ring 424. Two opposing first sliding grooves (not shown) extending along their own axis are formed on the wall of the first sliding hole. The two first sliders 425 are respectively located in the two first sliding grooves and slide in cooperation with them. It can be understood that in this embodiment, two opposing first sliders 425 are provided on the outer wall of the limiting ring 424, and two opposing first sliding grooves are formed on the wall of the limiting hole. The first sliding rod 421 slides stably within the first sliding hole through the sliding cooperation of the two first sliders 425 with the two first sliding grooves.

[0038] In one embodiment, the sliding ring 414 includes a middle ring 4142 and two side rings 4143. The two side rings 4143 are respectively disposed on opposite sides of the middle ring 4142. Each side ring 4143 has a first inclined surface 4141 that is inclined toward the limiting rod 411. The limiting head 412 has an annular groove 4121 on the side near the sliding ring 414, which is used to accommodate the side ring 4143 near the limiting head 412, or to accommodate the middle ring 4142 and the side ring 4143 near the limiting head 412 when the sliding ring 414 abuts against the limiting head 412. The side ring 4143 allows the first inclined surface 4141 of the side ring 4143, which is away from the limit head 412, to connect with the side wall of the limit head 412 when the sliding ring 414 abuts against the limit head 412. In this way, during the process of releasing the engagement between the main limit structure 410 and the secondary limit structure 420, the limit block 422 can slide along the first inclined surface 4141 of the side ring 4143, which is away from the limit head 412, to the side wall of the limit head 412, so that the limit block 422 can pass over the sliding ring 414 and the limit head 412 in sequence. Of course, in other embodiments, the side ring 4143 near the limiting head 412 can be omitted. In this case, the annular groove 4121 is only used to accommodate the middle ring 4142. The middle ring 4142 and the side ring 4143 near the limiting head 412 can even be omitted. In this case, the annular groove 4121 does not need to be opened on the side of the limiting head 412 near the sliding ring 414.

[0039] As one embodiment, the outer surface of the limiting head 412 is an arc surface, such as a hemispherical structure. That is, the limiting head 412 includes a connected hemispherical surface and a plane. The plane of the limiting head 412 can be set on the end of the limiting rod 411 that is not connected to the fixing member 300. Then, during the process of engaging the main limiting structure 410 and the secondary limiting structure 420, the hemispherical surface of the limiting head 412 will abut against the second inclined surface 4221 of the limiting block 422. The relative sliding between the two will be smoother, and the limiting block 422 will be easier to pass over the limiting head 412, thereby realizing the engagement between the main limiting structure 410 and the secondary limiting structure 420.

[0040] In some embodiments, still refer to Figures 1 to 4 In addition to the structure described above, the portable fire extinguishing bomb also includes an elastic member 500 disposed on the base 210 and located between the two partitions 220. The elastic member 500 is used to: be compressed by the connecting rod 330 when the main limiting structure 410 is inserted into the corresponding limiting hole and engaged with the corresponding secondary limiting structure 420; or, during the process of releasing the engagement between the main limiting structure 410 and the secondary limiting structure 420, use its own elasticity as a pulling force. Understandably, during the engagement of the main limiting structure 410 with the corresponding secondary limiting structure 420, the elastic element 500 is compressed by the connecting rod 330 between the two partitions 220. During the disengagement of the engagement between the main limiting structure 410 and the secondary limiting structure 420, when the limiting head 412 abuts against the limiting rod 411 and is located between the sliding ring 414 and the fixed ring 413, the user can release the force. Subsequently, the elastic force of the elastic element 500 (equivalent to the pulling force) will push the connecting rod 330 upward, and at the same time drive the limiting rod 411 upward, so that the limiting block 422 passes over the sliding ring 414 and the limiting head 412 in sequence, thereby disengaging the main limiting structure 410 from the limiting hole, and thus separating the fire extinguishing projectile 100 from the fixed block 200.

[0041] As one example, please refer to Figure 5 , Figure 5The diagram shows the structure of the elastic component 500, which includes a support plate 510, a second sliding rod 530, a second spring 540, and two second sliders 520. The support plate 510 is disposed in the gap 221 between the two partitions 220. The two second sliders 520 are respectively disposed on opposite sides of the support plate 510. The inner sides of the two partitions 220 are provided with second sliding grooves (not shown). The two second sliders 520 are respectively located in the two second sliding grooves and are slidably engaged with the two second sliding grooves. The base 210 is provided with a second sliding hole (not shown) located between the two partitions 220. One end of the second sliding rod 530 is disposed on the side of the support plate 510 near the base 210, and the other end of the second sliding rod 530 is inserted into the second sliding hole and is slidably engaged with the second sliding hole. The second spring 540 is sleeved on the second sliding rod 530, with one end of the second spring 540 disposed in the second sliding hole and the other end abutting against the support plate 510. Of course, the combination of the second slide bar 530, the second spring 540 and the second sliding hole is not limited to one set. In other embodiments, the elastic element 500 may also include two or more such combinations. The specific combination can be set according to actual needs. This application does not limit it to a single combination.

[0042] Understandably, the elastic force of the elastic element 500 is provided by the second spring 540. During the engagement of the main limiting structure 410 and the secondary limiting structure 420, the connecting rod 330, which enters between the two partitions 220, presses down on the support plate 510. The support plate 510 moves downward through the sliding cooperation of the second slider 520 and the second sliding groove, thereby compressing the second spring 540. During the disengagement of the engagement between the main limiting structure 410 and the secondary limiting structure 420, when the limiting head 412 abuts against the limiting rod 411 and is located between the sliding ring 414 and the fixed ring 413, the user can release the force. Subsequently, the elastic force of the second spring 540 can push the support plate 510 upward, thereby driving the limiting rod 411 upward, and finally causing the limiting block 422 to pass over the sliding ring 414 and the limiting head 412 in sequence, thereby removing the main limiting structure 410 from the limiting hole, and thus separating the fire extinguishing projectile 100 from the fixed block 200.

[0043] In some embodiments, still refer to Figures 1 to 5In addition to the structure described above, the portable fire extinguishing grenade also includes a handle 600, which is disposed on the outer wall of the fire extinguishing grenade body 100 and located at the top of the fire extinguishing grenade body 100. In one embodiment, the handle 600 includes a connecting rod 620 and two support rods 610. One end of each support rod 610 is disposed opposite to and spaced apart on the outer wall of the fire extinguishing grenade body 100, and the connecting rod 620 connects the other ends of the two support rods 610. In practical applications, the user can hold the connecting rod 620 and apply pressure to the main limiting structure 410 by pressing the connecting rod 620, and apply pulling force to the main limiting structure 410 by pulling the connecting rod 620.

[0044] The above embodiments are merely preferred implementations of this application and are not the only limitation on the content related to portable fire extinguishing bombs. Those skilled in the art can flexibly customize the above embodiments according to actual application scenarios. It is understood that through the implementation of the above embodiments of this application, a portable fire extinguishing bomb is constructed using a fixing block 200, a limiting member 400, and a fire extinguishing bomb body 100. The fixing block 200 is used to be installed on a wall and has a limiting hole. The limiting member 400 includes a main limiting structure 410 and a secondary limiting structure 420. The main limiting structure 410 is disposed on the outer wall of the fire extinguishing bomb body 100, and the secondary limiting structure 420 is disposed within the limiting hole. The main limiting structure 410 is inserted into the limiting hole, and a pressing force is applied to the main limiting structure 410 to move it into the limiting hole, thereby securing the main limiting structure 410. The main limiting structure 410 engages with the secondary limiting structure 420 within the limiting hole. At this time, the main limiting structure 410 is confined within the limiting hole, and the fire extinguishing projectile 100 and the fixing block 200 are relatively fixed. When the main limiting structure 410 and the secondary limiting structure 420 are engaged, a pressing force is first applied to the main limiting structure 410, and then a pulling force is applied to the main limiting structure 410 to move it out of the limiting hole, so as to release the engagement between the main limiting structure 410 and the secondary limiting structure 420. At this time, the main limiting structure 410 disengages from the limiting hole, and the fire extinguishing projectile 100 separates from the fixing block 200. Therefore, this application can easily fix the fire extinguishing shell 100 to the wall by applying pressure to the main limiting structure 410, and can easily remove the fire extinguishing shell 100 from the wall by applying pressure and pulling force to the main limiting structure 410 successively. The fire extinguishing shell 100 can be placed on the wall in any location, such as on the wall near a small, hidden corner or a place with low traffic. This can improve the convenience of using the fire extinguishing shell, and when a fire occurs in these locations, it is easier to retrieve the fire extinguishing shell, and the whole process of retrieving the fire extinguishing shell takes less time, which is very beneficial to fire rescue.
