Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, and more specifically, to a double-door structure and a fire truck. Background Technology

[0002] As an important component of the vehicle, the double rear doors of the fire truck not only need to meet the requirements of rapid entry and exit and loading of equipment, but also need to have good waterproof performance to protect the equipment inside the vehicle from rainwater corrosion.

[0003] In existing technologies, the design of double doors at the rear of fire trucks typically uses simple sealing strips or rubber gaskets for waterproofing. However, this design often has certain limitations in practical use. To avoid interference, the middle section of the double doors usually requires a relatively large gap, making it difficult for the sealing strip to fit completely, which can easily lead to water leakage. Especially in inclement weather conditions, rainwater can easily seep into the vehicle through the gaps, affecting the normal operation of the equipment inside. Utility Model Content

[0004] The purpose of this utility model is to provide a double-door structure and fire truck that can prevent water leakage from the gap between the double doors at the rear of the fire truck and improve the sealing performance between the double doors.

[0031] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0032] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0033] Please refer to Figure 1 The double-door structure 100 provided by this utility model is applied to fire trucks. Specifically, the double-door structure 100 is located at the rear of the fire truck, that is, at the rear of the fire truck compartment, and is used to open or close the fire truck compartment.

[0034] The double-door structure 100 includes a door frame 30, a first door panel 10, and a second door panel 20. The first door panel 10 and the second door panel 20 are positioned between the door frame 30. The first door panel 10 and the second door panel 20 are hinged to the door frame 30 to form a double-door structure. It can be understood that the left side of the first door panel 10 is hinged to the door frame 30, and the right side of the second door panel 20 is hinged to the door frame 30. When the double-door structure 100 is open, the first door panel 10 rotates to the left, and the second door panel 20 rotates to the right; when the double-door structure 100 is closed, the first door panel 10 rotates to the right again, and the second door panel 20 rotates to the left again, until both the first door panel 10 and the second door panel 20 are located within the plane of the door frame 30.

[0035] Understandably, in this embodiment, the door frame 30 is fixed to the rear of the fire truck. The fire truck compartment is opened by pulling the first door panel 10 and the second door panel 20 outwards; and the fire truck compartment is closed by pushing the first door panel 10 and the second door panel 20 inwards.

[0036] Please refer to Figure 2 Furthermore, the first door panel 10 and the second door panel 20 are respectively provided with a first snap-on assembly 11 and a second snap-on assembly 21 facing opposite directions on the sides of the first door panel 10 and the second door panel 20. When the first door panel 10 and the second door panel 20 are closed, the first snap-on assembly 11 and the second snap-on assembly 21 engage with each other to seal the first door panel 10 and the second door panel 20.

[0037] Specifically, when the first door panel 10 and the second door panel 20 are closed, a gap is provided between the first door panel 10 and the second door panel 20, and the first snap plate assembly 11 and the second snap plate assembly 21 are disposed between the gap to seal the gap.

[0038] It is understood that, in this embodiment, to avoid interference, when the first door panel 10 and the second door panel 20 are located within the plane of the door frame 30, there is a gap between the first door panel 10 and the second door panel 20. By setting the gap, the first door panel 10 and the second door panel 20 will not come into contact when closed.

[0039] By creating a gap between the first door panel 10 and the second door panel 20, the requirements for the precision of the design dimensions and the installation position of the first door panel 10 and the second door panel 20 are relatively relaxed. That is, the design dimensions of the first door panel 10 and the second door panel 20 can be slightly larger or smaller. When the installation position of the first door panel 10 and the second door panel 20 is offset or the door frame 30 and the door panel are deformed, the first snap-on assembly 11 and the second snap-on assembly 21 can still form an interlocking structure in the gap, without affecting the sealing performance of the double door structure 100.

[0040] When the first door panel 10 and the second door panel 20 are closed, the first snap-on assembly 11 and the second snap-on assembly 21 form an interlocking structure to seal the aforementioned gap.

[0041] Specifically, the first snap-on assembly 11 includes a first connecting plate 111 and a first snap-on plate 112. The second snap-on assembly 21 includes a second connecting plate 211 and a second snap-on plate 212. The first connecting plate 111 connects the first door panel 10 and the first snap-on plate 112 such that the first snap-on plate 112 and the first door panel 10 are spaced apart. The second connecting plate 211 connects the second door panel 20 and the second snap-on plate 212 such that the second snap-on plate 212 and the second door panel 20 are spaced apart. The first snap-on plate 112 and the second snap-on plate 212 face opposite directions. It is understood that when the first door panel 10 and the second door panel 20 are closed, the first snap-on plate 112 is located between the second snap-on plate 212 and the second door panel 20, and the second snap-on plate 212 is located between the first snap-on plate 112 and the first door panel 10, thereby sealing the gap between the first door panel 10 and the second door panel 20, preventing water from outside the fire truck from entering the interior from between the first door panel 10 and the second door panel 20.

[0042] By setting the first connecting plate 111, a groove is formed between the first snap plate 112 and the first door panel 10. By setting the second connecting plate 211, a groove is formed between the second snap plate 212 and the second door panel. When the first door panel 10 and the second door panel 20 are closed, the first snap plate 112 engages with the groove between the second door panel 20 and the second snap plate 212, and the second snap plate 212 engages with the groove between the first door panel 10 and the first snap plate 112. The first connecting plate 111 and the second connecting plate 211 isolate the interior and exterior of the double door structure 100, and rainwater flows downward along the aforementioned grooves, preventing it from entering the interior of the vehicle, thus improving the sealing performance of the double door structure 100.

[0043] Further, in this embodiment, the first connecting plate 111 is connected to the inner side of the first door panel 10, and the first buckle plate 112 is disposed facing the outer side of the first door panel 10. The second connecting plate 211 is connected to the outer side of the second door panel 20, and the second buckle plate 212 is disposed facing the inner side of the second door panel 20. When the double door structure 100 is closed, the first door panel 10 is closed first, and then the second door panel 20 is closed. First, the first connecting plate 111 and the first buckle plate 112 are pushed into the door frame 30. At this time, the first connecting plate 111 is located inside the first door panel 10, and the first buckle plate 112 is disposed facing the outer side, forming a groove between the first buckle plate 112 and the first door panel 10; then the second door panel 20 is closed, and the second connecting plate 211 and the second buckle plate 212 are pushed into the door frame 30, that is, the second buckle plate 212 is pushed into the groove between the first buckle plate 112 and the first door panel 10. Correspondingly, as the second snap plate 212 enters the groove of the first snap plate 112 and the first door panel 10, the first snap plate 112 also enters the groove of the second snap plate 212 and the second door panel 20.

[0044] It is understood that the orientation of the first buckle plate 112 refers to the direction from the connection point between the first buckle plate 112 and the first connecting plate 111 to the end away from the first connecting plate 111. The orientation of the second buckle plate 212 refers to the direction from the connection plate between the second buckle plate 212 and the second connecting plate 211 to the end away from the second connecting plate 211.

[0045] Optionally, in other embodiments, the following configuration may be used: a first connecting plate 111 is connected to the outer side of the first door panel 10, and a first buckle plate 112 is disposed facing the inner side of the first door panel 10. A second connecting plate 211 is connected to the inner side of the second door panel 20, and a second buckle plate 212 is disposed facing the outer side of the second door panel 20. When the double door structure 100 is closed, the second door panel 20 is closed first, and then the first door panel 10 is closed. The second connecting plate 211 and the second buckle plate 212 are first pushed into the door frame 30. At this time, the second connecting plate 211 is located inside the second door panel 20, and the second buckle plate 212 is disposed facing the outer side, forming a groove between the second buckle plate 212 and the second door panel 20. Then, the first door panel 10 is closed, and the first connecting plate 111 and the first buckle plate 112 are pushed into the door frame 30, that is, the first buckle plate 112 is pushed into the groove of the second buckle plate 212 and the second door panel 20. Correspondingly, as the first snap plate 112 enters the grooves of the second snap plate 212 and the second door panel 20, the second snap plate 212 also enters the grooves of the first snap plate 112 and the first door panel 10. That is, the orientation of the first snap plate 112 and the second snap plate 212 is opposite to that in this embodiment. As long as the first snap plate assembly 11 and the second snap plate assembly 21 can achieve interlocking and sealing, the present invention does not limit the orientation of the first snap plate 112 and the second snap plate 212.

[0046] In this embodiment, the first connecting plate 111 and the first buckle plate 112 are vertically connected. The second connecting plate 211 and the second buckle plate 212 are vertically connected. That is, in this embodiment, the first buckle plate assembly 11 and the second buckle plate assembly 21 are both L-shaped bent plate structures.

[0047] Furthermore, the length of the first snap plate 112 is less than the thickness of the first door panel 10 and / or the second door panel 20. The length of the second snap plate 212 is less than the thickness of the first door panel 10 and / or the second door panel 20. That is, when the first door panel 10 and the second door panel 20 are closed, the first door panel 10 and the second door panel 20 are located in the same plane, and the first snap plate 112 will not contact the second connecting plate 211, nor will the second snap plate 212 contact the first connecting plate 111.

[0048] Please continue to refer to Figure 1 In this embodiment, both the first door panel 10 and the second door panel 20 are provided with door lock assemblies 12 for locking the first door panel 10 and the second door panel 20 respectively.

[0049] Please refer to Figure 3Furthermore, both the first door panel 10 and the second door panel 20 include a frame 13 and a sealing plate 14. The sealing plate 14 covers the frame 13. Specifically, the sealing plate 14 is fixed to the outside of the frame 13 by adhesive bonding.

[0050] The frame 13 comprises multiple profiles joined end-to-end in sequence. Sealing strips are embedded in the profiles to further improve the sealing performance of the double-door structure 100.

[0051] The double-door structure 100 provided by this utility model includes a door frame 30, a first door panel 10, and a second door panel 20. The first door panel 10 and the second door panel 20 are disposed between the door frame 30 and are hinged to the door frame 30 respectively, so that the first door panel 10 and the second door panel 20 form a double-door structure. On the side of the first door panel 10 and the second door panel 20 that are close to each other, a first snap-on assembly 11 and a second snap-on assembly 21 facing opposite directions are respectively provided. When the first door panel 10 and the second door panel 20 are closed, the first snap-on assembly 11 and the second snap-on assembly 21 are engaged with each other to seal the first door panel 10 and the second door panel 20. By setting the first snap plate assembly 11 and the second snap plate assembly 21, the gap between the first door panel 10 and the second door panel 20 can be sealed when the first door panel 10 and the second door panel 20 are closed. Compared with setting a sealing strip, this utility model can achieve sealing of the gap between the first door panel 10 and the second door panel 20 without the edges of the first door panel 10 and the second door panel 20 contacting each other, thereby improving the sealing performance of the double door structure 100.

[0052] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
