Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting equipment, in particular to a fire hydrant box. Background Art

[0002] Fire hydrant boxes are a crucial component of a building's fire protection system, storing and protecting fire hydrant equipment so that firefighting operations can be carried out quickly and effectively in the event of a fire. Fire hydrant boxes are typically installed in public areas of a building, such as corridors and stairwells, in easily accessible and conspicuous locations, ensuring they can be quickly found and used in an emergency.

[0003] With the development of the construction industry, cost reduction has become a consensus goal. Various building floor plans are evolving towards solutions that conserve ineffective space. Underground garages, as a crucial component, are no exception. Conventional underground garage structures typically have square columns. However, to reduce ineffective space and resource waste between parking spaces, some architectural designs with narrow rectangular columns are gradually emerging. Fire hydrant boxes are mounted on these columns, with the door located on the side closest to the parking space. Parking in these spaces can prevent the door from opening.

[0004] Some fire hydrant boxes in related technologies are difficult to open in a narrow space because the space required to open the box door is large. When the fire-fighting equipment in the fire hydrant box is needed, it is difficult to open it, which poses a safety hazard. Summary of the Invention

[0005] The purpose of the present invention includes providing a fire hydrant box, which can reduce the space required to open the box door so that the fire hydrant box door can be opened smoothly in some narrow spaces, thereby improving the convenience of firefighters in opening the fire hydrant box and reducing safety hazards.

[0032] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the product of the invention is usually placed when in use. It 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. Therefore, it should not be understood as a limitation on the present invention.

[0033] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0034] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0035] The specific structure of a fire hydrant box 1 provided by an embodiment of the present invention and the corresponding technical effects thereof are described in detail below with reference to the patent drawings.

[0036] Please refer to Figure 1A fire hydrant box 1 provided by an embodiment of the present invention includes a box body 100, a connecting assembly 200, and a box door 300. The box body 100 has an opening 101. The connecting assembly 200 includes a first connecting member 210 and a second connecting member 220 connected to each other. The first connecting member 210 is connected to the box body 100, and the second connecting member 220 can move along a preset path relative to the second connecting member 220. The box door 300 includes a connecting portion 301 and a free end 302. The connecting portion 301 is connected to the second connecting member 220. The box door 300 can move along the preset path along with the second connecting member 220 to open or close the opening 101. In the process of the box door 300 moving along the preset path to open the opening 101, the connecting portion 301 gradually moves away from the opening 101.

[0037] It should be noted that the box 100 in this embodiment is used to install fire-fighting equipment. When the opening 101 is closed, it means that the box door 300 closes the box 100, and personnel cannot take out the fire-fighting equipment in the box 101 from the opening 101. When the opening 101 is complete, it means that personnel can take out the fire-fighting equipment in the box 101 from the opening 101 without being interfered with by the box door 300.

[0038] Since the connecting portion 301 gradually moves away from the opening 101 when the door 300 moves along the preset path to open the opening 101 , the space required by the free end 302 when opening can be reduced.

[0039] It can be understood that the space required for opening the door 300 generally refers to the space in the depth direction with the opening 101 facing upward. During the opening process of the door 300 in this embodiment, the connecting portion 301 gradually moves away from the opening 101. Compared with some existing fire hydrant boxes 1 with fixed connecting portions 301 of the door 300, it can reduce the expansion space required for the free end 302 of the door 300 when the door 300 is opened, so that the door 300 of the fire hydrant box 1 can be opened smoothly in some narrow spaces, thereby improving the convenience of firefighters in opening the fire hydrant box 1 and reducing safety hazards.

[0040] It should be noted that the free end 302 of the door 300 is used to connect with the side panel of the box body 100 when closed, so as to lock the door 300 and the box body 100. Since the locking structure of the door 300 and the box body 100 is a conventional setting in the field of mechanical structure, it is not restricted here.

[0041] In detail, the box body 100 in this embodiment includes a back panel 150 and multiple side panels, and the multiple side panels are connected end to end in sequence around the circumference of the back panel 150. In the depth direction of the box body 100, the side panels have a first side and a second side relative to each other. The first side of the side panel is connected to the back panel 150, and the second side is used to cooperate with the box door 300 to close the opening 101 of the box door 300.

[0042] For ease of understanding, the multiple side panels in this embodiment can be divided into a first side panel 110, a second side panel 120, a third side panel 130, and a fourth side panel 140. The first side panel 110 and the third side panel 130 are arranged on both sides of the back panel 150 along the first direction, and the second side panel 120 and the fourth side panel 140 are arranged on both sides of the back panel 150 along the second direction. The first side panel 110, the second side panel 120, the third side panel 130, and the fourth side panel 140 are connected end to end in sequence along the circumference of the back panel 150. It can be understood that the back panel 150, the first side panel 110, the second side panel 120, the third side panel 130, and the fourth side panel 140 together define a space for placing firefighting equipment.

[0043] Please refer to Figures 1-4 Optionally, in some embodiments, the first connecting member 210 rotates relative to the second connecting member 220 around the first axis 201, the first connecting member 210 is connected to the side wall of the box body 100, the connecting portion 301 is rotatably connected to the second connecting member 220, and the door 300 can rotate relative to the second connecting member 220 around the second axis 202 to open or close the opening 101, and the first axis 201 is parallel to the second axis 202.

[0044] The first axis 201 and the second axis 202 are both parallel to the first direction.

[0045] It can be understood that the door 300 can rotate around the first axis 201 relative to the first connecting member 210 along with the second connecting member 220, and the door 300 can also rotate around the second axis 202 relative to the second connecting member 220, so as to open or close the opening 101 of the box body 100 during its rotation. Since the door 300 can rotate around the first axis 201 relative to the first connecting member 210 along with the second connecting member 220, the relative position of the connecting part 301 and the opening 101 of the box body 100 can be changed during the process of opening or closing the opening 101 of the box body 100, that is, when the opening 101 is closed, the connecting part 301 can gradually move away from the opening 101.

[0046] Therefore, in this embodiment, the door 300 can rotate relative to both the first axis 201 and the second axis 202. Even if one of the rotational connection between the first connector 210 and the second connector 220 or the rotational connection between the connecting portion 301 and the second connector 220 fails, the other one can still enable the door 300 to open. For example, when the door 300 closes the opening 101 and the rotational connection between the first connector 210 and the second connector 220 fails, the door 301 can still open the opening 101 because the second connector 220 can be rotationally connected relative to the connecting portion 301 of the door 300. Even when the door 300 closes the opening 101 and the rotational connection between the second connector 220 and the connecting portion 301 fails, the door 301 can still open the opening 101 because the second connector 220 is rotationally connected to the first connector 210.

[0047] Compared with the traditional door 300 that rotates only about one rotation axis, it has higher reliability and fault redundancy capability, and can avoid the problem that the door 300 cannot be opened due to the failure of a single rotation axis.

[0048] Optionally, the first connecting member 210 and the second connecting member 220 may be rotatably connected by a hinge, and the connecting portion 301 of the door 300 may also be rotatably connected to the second connecting member 220 by a hinge.

[0049] Optionally, in the depth direction of the box body 100 , the first axis 201 is located on the first side or between the first side and the second side of the side plate.

[0050] It is understandable that in order to ensure the connection strength between the door 300 and the box body 100, a plurality of connection components 200 may be connected to the door 300, and the plurality of connection components 200 are spaced apart along a first direction perpendicular to the preset path.

[0051] In addition, the door 300 is connected to the box body 100 through multiple connecting components 200. That is, when any connecting component 200 fails, the other connecting components 200 can still independently realize the opening and closing functions of the door 300. Compared with the traditional single-axis structure, it has higher reliability and fault redundancy capability, avoiding the problem of the door 300 being unable to open due to the failure of a single structure.

[0052] It should be noted that the term "plurality" in this application document can be understood as two or more. The term "perpendicular" in this embodiment should not be limited to being perpendicular in the strict sense, as long as the two are approximately perpendicular. The term "parallel" in this embodiment should not be limited to being parallel in the strict sense, as long as the two are approximately parallel.

[0053] Of course, in some other embodiments, the door 300 may also be connected to the box body 100 via only one connecting assembly 200 .

[0054] That is, the hinge of the first connecting member 210 and the second connecting member 220 can be set on the first side of the side plate, or can be located between the first side and the second side of the side plate. Figure 2 The hinge between the first connecting member 210 and the second connecting member 220 is located in the middle of the second side plate 120 .

[0055] Of course, in some other optional embodiments, the hinge between the first connecting member 210 and the second connecting member 220 may also be located at other positions between the first side and the second side of the side panel, which is not limited here.

[0056] In detail, in this embodiment, the first connecting member 210 is fitted with the side panel. When the door 300 closes the opening 101, the first connecting member 210 is fitted with the second connecting member 220. It can be understood that since the first connecting member 210 is fitted with the side panel and the first connecting member 210 is fixedly connected to the side panel, the connection strength between the first connecting member 210 and the side panel can be guaranteed, and the first connecting member 210 can be prevented from being easily deformed.

[0057] In detail, in this embodiment, the first connecting member 210 is disposed on the outer side of the second side panel 120 and is in contact with the second side panel 120. Of course, in other embodiments, the first connecting member 210 can also be disposed on the outer side of the fourth side panel 140 and is in contact with the outer wall of the fourth side panel 140.

[0058] Moreover, since the first connecting member 210 is fitted with the second connecting member 220 when the door 300 closes the opening 101 of the box body 100, the first connecting member 210 can serve as the second connecting member 220 in the limiting portion to prevent the second connecting member 220 from excessively rotating around the second axis 202 relative to the first connecting member 210.

[0059] Among them, please refer to Figure 1-Figure 2 The first connecting member 210 and the second connecting member 220 can be plate-shaped structures to ensure that the first connecting member 210 and the second connecting member 220 have good bending resistance in the first direction, thereby ensuring the service life of the connecting component 200.

[0060] Please refer to Figure 3-Figure 4 Of course, in some other embodiments, the first connecting member 210 may not be a plate-shaped structure, as long as the second connecting member 220 can rotate around the first axis 201 relative to the first connecting member 210 after the first connecting member 210 is connected to the side panel of the box body 100.

[0061] Optionally, at least one of the first side panel 110, the second side panel 120, the third side panel 130 and the fourth side panel 140 is connected with a first connecting member 210. It can be understood that at least one of the first side panel 110, the second side panel 120, the third side panel 130 and the fourth side panel 140 is connected with a connecting component 200.

[0062] Alternatively, refer to Figure 4 In some embodiments, the first connecting member 210 can also be connected to the first side panel 110, that is, the first connecting member 210 is installed on the top plate of the box body 100. In order to ensure the stability of the connection, the first connecting member 210 can also be connected to the outer wall of the third side panel 130 opposite to the first side panel 110. Of course, the first connecting member 210 can also be set on the first side panel 110, and the first connecting member 210 on the first side panel 110 can be located in the middle of the first side panel 110 in the first direction.

[0063] Of course, in some other embodiments, please refer to Figure 1-Figure 3 , the connection assembly 200 can be set only on the second side plate 120 of the box body 100.

[0064] Optionally, in some other embodiments, the connection assembly 200 is not limited to the above structure. Figure 5 The first connecting member 210 includes an arc track, which is connected to the box body 100 and extends along a preset path. The arc track has a first position and a second position spaced apart on the preset path. The second position is closer to the opening 101 relative to the first position. The second connecting member 220 is connected to the arc track and can move on the arc track. When the second connecting member 220 moves from the first position to the second position, the box door 300 opens the opening 101.

[0065] One end of the arc track may be located inside the box 100 and disposed on the back plate 150 .

[0066] In this embodiment, when the door 300 opens or closes the opening 101 of the box body 100 , the connecting portion 301 of the door 300 does not need to rotate relative to the second connecting member 220 , and the connecting portion 301 can be fixedly connected to the second connecting member 220 .

[0067] In detail, the second connecting member 220 is arc-shaped and adapted to the arc-shaped track. The second connecting member 220 has a movable portion. When the box door 300 closes the opening 101, the movable portion is opposite to the first position. That is, when the movable portion moves to the first position on the arc-shaped track, the box door 300 can close the opening 101 of the box body 100.

[0068] Optionally, in some embodiments, when the door 300 closes the opening 101 , in order to reduce interference of the arc track on the door 300 , when the door 300 closes the opening 101 , the end of the second connecting member 220 away from the moving part is located outside the arc track.

[0069] It should be noted that, in the above embodiment, the box body 100 is opened and closed by only one door 300 .

[0070] Alternatively, in some other embodiments, there may be two doors 300, which are spaced apart along the width direction of the box body 100. It should be noted that the width direction of the box body 100 is consistent with the second direction described above. The doors 300 are connected to the box body 100 via the connecting assembly 200, and the two doors 300 can cooperate with each other to close the opening 101. The two doors 300 are opened simultaneously to open the opening 101.

[0071] It can be understood that by providing two doors 300 , the space required by the free end 302 of the door 300 when the door 300 is opened can be further reduced.

[0072] In summary, an embodiment of the present invention provides a fire hydrant box 1, which includes a box body 100, a connecting assembly 200, and a box door 300. The box body 100 has an opening 101, and the connecting assembly 200 includes a first connecting member 210 and a second connecting member 220 connected to each other. The first connecting member 210 is connected to the box body 100, and the second connecting member 220 can move along a preset path relative to the second connecting member 220. The box door 300 includes a connecting portion 301 and a free end 302. The connecting portion 301 is connected to the second connecting member 220. The box door 300 can move along the preset path along with the second connecting member 220 to open or close the opening 101. In the process of the box door 300 moving along the preset path to open the opening 101, the connecting portion 301 gradually moves in a direction away from the opening 101. It can reduce the expansion space required by the free end 302 of the door 300 when the door 300 is opened, so that the door 300 of the fire hydrant box 1 can be opened smoothly in some narrow spaces, thereby improving the convenience of firefighters in opening the fire hydrant box 1 and reducing safety hazards.

[0073] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the scope of protection of the present invention.
