Description

Technical Field

[0001] This utility model relates to the field of fire extinguisher testing technology, specifically to a fire extinguishing box. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] Portable carbon dioxide fire extinguishers contain carbon dioxide gas in a two-phase gas-liquid state. Due to the special nature of this two-phase existence, the pressure inside the canister remains constant when carbon dioxide gas leaks (the pressure remains constant when the liquid changes into a gas). Therefore, the pressure gauge on a carbon dioxide fire extinguisher is essentially useless and cannot truly determine whether the fire extinguisher is up to standard.

[0004] Currently, carbon dioxide fire extinguishers are tested by weighing; if the weight is below a certain value, the extinguisher is deemed unqualified. However, this method is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0005] To address the shortcomings mentioned in the background section, this utility model provides a fire extinguishing box.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a fire extinguishing box, including a box body for holding fire extinguishers, a support plate is provided on the bottom inner side of the box body, and the fire extinguishers located inside the box body are placed on the support plate;

[0007] An elastic element is provided between the support plate and the box body. The elastic element is used to push the support plate to move upward so that the support plate is always kept in a suspended state.

[0008] A vertical through slot is provided at the position of the corresponding support plate of the box body. A mark is provided on one side of the corresponding through slot on the outside of the box body. An indicator block is provided at the position of the corresponding through slot on the support plate. One end of the indicator block extends out of the through slot and is used to cooperate with the mark to display the current position of the support plate relative to the box body.

[0009] Furthermore, the marking is a colored warning strip set on the outside of the box. When the weight of the fire extinguisher is qualified, the height of the indicator block is lower than the bottom of the warning strip; when the weight of the fire extinguisher is unqualified, the indicator block moves upward with the support plate, so that the height of the indicator block is higher than the bottom of the warning strip.

[0010] Furthermore, the marking also includes a regular color band located below the warning color band; when the fire extinguisher's weight is within acceptable limits, the indicator block is located in the area to one side of the regular color band.

[0011] Furthermore, the warning color band is divided into two areas, with the upper area being the unqualified color band and the lower area being the transition color band, used to indicate the degree of leakage of the fire extinguisher inside the box, respectively.

[0012] Furthermore, the support plate inside the box is a single plate, and multiple fire extinguishers are supported on the support plate.

[0013] Furthermore, the housing contains multiple support plates, each supporting a fire extinguisher, and multiple elastic elements are provided, located between each support plate and the housing.

[0014] The beneficial effects of this utility model are reflected in:

[0015] With this invention, inspectors only need to observe the position of the indicator block relative to the mark to know whether the carbon dioxide fire extinguisher in the box is leaking. There is no need to spend time and effort to take the carbon dioxide fire extinguisher out of the box and weigh it. It is efficient, fast and labor-saving. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, and not all of them. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the scope of protection of the utility model.

[0024] See Figures 1 to 4 .

[0025] Example 1:

[0026] This utility model discloses a fire extinguishing box, including a box body 1 for holding fire extinguishers, and a support plate 2 is provided on the bottom inner side of the box body 1, and the fire extinguishers located inside the box body 1 are placed on the support plate 2.

[0027] An elastic element 3 is provided between the support plate 2 and the box 1. The elastic element 3 is used to push the support plate 2 upward so that the support plate 2 is always suspended.

[0028] The box 1 has a vertical through groove 11 at the position of the corresponding support plate 2. A mark is provided on one side of the corresponding through groove 11 on the outside of the box 1. An indicator block 21 is provided at the position of the corresponding through groove 11 on the support plate 2. One end of the indicator block 21 extends out of the through groove 11 and is used to cooperate with the mark to display the current position of the support plate 2 relative to the box 1.

[0029] In practice, the carbon dioxide fire extinguisher is placed on the support plate 2. Under the action of gravity, the support plate 2 will overcome the elastic force of the elastic element 3 and drive the indicator block 21 to move downwards in the box 1 until it stops moving after reaching a certain height. At this time, the weight of the fire extinguisher and the elastic force of the elastic element 3 are balanced. When the fire extinguisher leaks gas, the weight of the fire extinguisher body becomes lighter, and the elastic force of the elastic element 3 pushes the support plate 2 to move upwards. Since the indicator block 21 moves upwards with the support plate 2, it can be determined whether the carbon dioxide fire extinguisher in the box 1 is leaking gas by observing the position of the corresponding mark on the indicator block 21.

[0030] With this invention, inspectors only need to observe the position of the indicator block 21 relative to the mark to know whether the carbon dioxide fire extinguisher in the box 1 is leaking. There is no need to spend time and effort to take the carbon dioxide fire extinguisher out of the box 1 and weigh it. It is efficient, fast and requires less labor.

[0031] Preferably, the elastic element 3 is a spring. This spring can be available in various sizes to accommodate different sizes of carbon dioxide fire extinguishers.

[0032] In one embodiment, the marking is a colored warning strip 12 located on the outside of the housing 1. When the fire extinguisher's weight is within acceptable limits, the height of the indicator block 21 is below the bottom of the warning strip 12; when the fire extinguisher's weight is insufficient, the indicator block 21 moves upward along with the support plate 2, making its height higher than the bottom of the warning strip 12. With this design, inspectors only need to observe the position of the indicator block 21 relative to the warning strip 12 to determine whether the fire extinguisher inside the housing 1 is within acceptable limits or is leaking, enabling a simple and quick judgment.

[0033] In one embodiment, the marking also includes a conventional color band 13 located below the warning color band 12; when the fire extinguisher is of acceptable weight, the indicator block 21 is located in the area on one side of the conventional color band 13.

[0034] In practice, the setting of the conventional color strip 13 can, on the one hand, reveal to the inspectors that the fire extinguisher in the box 1 is qualified, and on the other hand, the different colored strips can facilitate the later visual inspection of the fire extinguisher's leakage status in the box 1.

[0035] Preferably, the conventional color strip 13 is green and has a certain width.

[0036] In one embodiment, the warning color band 12 is divided into two areas, with the upper area being the unqualified color band 121 and the lower area being the transition color band 122, which are used to indicate the degree of leakage of the fire extinguisher in the box 1, respectively.

[0037] In practice, when the indicator block 21 is located on one side of the transition color band 122, it indicates that the fire extinguisher in the box 1 has started to leak, reminding the inspection personnel to pay attention to the fire extinguisher in the box 1. When the indicator block 21 is located on one side of the unqualified color band 121, it indicates that the fire extinguisher in the box 1 is in an unqualified state, and the staff needs to replace the unqualified fire extinguisher in the box 1.

[0038] Preferably, the color of the non-conforming color band 121 is red, and the color of the transition color band 122 is orange.

[0039] Of course, the colors of the regular color band 13, the non-conforming color band 121, and the transition color band 122 in this application can also be other colors, as long as they can be distinguished from each other.

[0040] In one embodiment, the support plate 2 located inside the housing 1 is a single piece of plate, which supports multiple fire extinguishers. The advantages of this design are low production and assembly costs, simple structure, and the ability to individually weigh each fire extinguisher inside the housing 1 when the indicator block 21 is in the warning color band 12 area, thereby eliminating substandard fire extinguishers. This design still offers significant advantages compared to conventional methods.

[0041] Example 2:

[0042] The only difference between this embodiment and Embodiment 1 is the number of bearing plates 2 inside the housing 1:

[0043] like Figure 4As shown, in this embodiment, there are multiple support plates 2 inside the housing 1, each supporting a fire extinguisher. Multiple elastic elements 3 are correspondingly provided, located between each support plate 2 and the housing 1. The advantage of this design is that it allows for a direct visual identification of which fire extinguisher inside the housing 1 has leaked or is defective, eliminating the need for weighing and rejection, thus improving efficiency.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0045] It should be noted that if the utility model embodiment involves directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0046] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, if the utility model embodiments involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the utility model.
