[0024] Figure 1 The cross-sectional structure diagram of the profile provided by the present utility model is exemplified, as Figure 1As shown, the profile includes a profile body 100. The cross-section of the profile body 100 is rectangular. Of course, the cross-sectional shape of the profile body 100 is not limited to this and can also be set to other shapes, which is specifically determined according to actual needs. The interior of the profile body 100 has a cavity, and at least one connecting portion 110 is provided on the outer side of the side wall of the cavity to form a connecting area on the outer side of the side wall of the cavity. The area where the connecting portion 110 is not provided is the main body area. The connecting portion 110 is used to connect with the profile corner piece, thereby realizing the fixation of the profile. The thickness of the side wall provided with the connecting portion 110 is greater than the thickness of the side wall without the connecting portion 110, and the thickness of the side wall provided with the connecting portion 110 is 1.2 - 2 times the thickness of the side wall without the connecting portion 110.

[0025] For the profile provided by the present utility model, by making the thickness of the side wall provided with the connecting portion 110 greater than the thickness of the side wall without the connecting portion 110, the structural strength at the connection of the profile is enhanced, and the torsional resistance is stronger, avoiding deformation at the connection of the profile after being stressed, and solving the problem that the fire truck will vibrate during driving.

[0026] In an embodiment of the present utility model, the connecting portion 110 is used to connect with the profile corner piece, and connecting portions 110 are provided on both sides of both ends of the profile body 100. Specifically, one connecting portion 110 is provided on each side of both ends of the profile body 100. As Figure 1 shown, one connecting portion 110 is provided on each of the upper and lower sides of the left end of the profile body 100, and one connecting portion 110 is provided on each of the upper and lower sides of the right end of the profile body 100. In this embodiment, the connecting portion 110 is a plane. Of course, the structural form of the connecting portion 110 is not limited to this and is specifically determined according to actual needs.

[0027] Since connecting portions 110 are provided on both sides of each end of the profile body 100, thus both sides of each end of the profile body 100 have thickened side walls. The thickened side walls have higher structural strength, and the thickened side walls constitute the framework of the profile. The side walls with relatively thin thickness are located in the middle of the framework. By adopting such an arrangement method, the structural strength of the entire profile can be improved.

[0028] In an embodiment of the present utility model, since the structural strength of the superstructure frame on the vehicle mainly depends on the rigidity strength of the main profile, and the remaining profiles are for decoration and small profiles, therefore the structural strength of the main profile is the key to stability. The greater the thickness of the side wall provided with the connecting portion 110, the higher the structural strength of the profile and the better the stability. At the same time, the greater the thickness of the side wall provided with the connecting portion 110, the greater the weight of the profile and the higher the production cost. Therefore, when determining the thickness of the side wall provided with the connecting portion 110, multiple factors such as structural strength and production cost need to be comprehensively considered.

[0029] In an embodiment of the present utility model, the material of the profile body 100 is aluminum alloy. By using high-strength aluminum alloy profiles, it has the advantages of strong anti-deformation ability, flat and beautiful appearance, flexible assembly, convenient maintenance, stable and safe operation, high corrosion resistance, and long service life. Of course, the material of the profile body 100 is not limited thereto, and aluminum-magnesium alloy and other alloy materials can also be used.

[0030] In an embodiment of the present utility model, the thickness of any part of the side wall provided with the connecting portion 110 is equal, that is, the thickness of each part of the side wall provided with the connecting portion 110 is equal. Such a setting not only improves the structural strength and torsional resistance of the profile, but also simplifies the processing technology of the profile and reduces the production cost.

[0031] In an embodiment of the present utility model, the thickness of the profile body 100 is 3.5 mm - 4.5 mm. Preferably, the thickness of the profile body 100 is 4 mm. Since the thickness of the existing profiles is relatively thin and the cross-sectional area of the profiles is small, the structural strength of the profiles is low. In this embodiment, by increasing the thickness of the profile body 100, the cross-sectional area of the profile is increased, the overall structural strength of the profile is improved, and the stability is higher after the profile is installed, avoiding the problem of vibration during the driving of the fire truck.

[0032] It should be noted here that the thickness of the profile body 100 refers to the dimension of the profile in the Figure 1 up and down direction, the width of the profile body 100 refers to the dimension of the profile in the Figure 1 left and right direction, and the length of the profile body 100 refers to the dimension of the profile in the Figure 1 front and back direction.

[0033] In an embodiment of the present utility model, a plurality of convex ribs (not shown) are provided on the inner side of the side wall provided with the connecting portion 110. The plurality of convex ribs are arranged at intervals along the width direction of the profile body 100. The distance between adjacent two convex ribs can be the same or different. The convex ribs extend along the length direction of the profile body 100, and the width of each convex rib is the same. By providing convex ribs on the inner side of the side wall provided with the connecting portion 110, the structural strength of the side wall provided with the connecting portion 110 can be further improved without increasing the overall thickness of the side wall.

[0034] In a preferred embodiment of the present utility model, the distance between two adjacent convex ribs close to the connecting portion 110 is smaller, and the distance between two adjacent convex ribs far from the connecting portion 110 is larger. Since the profile is subjected to greater force at the position close to the connecting portion 110 and is prone to deformation, while the profile is subjected to less force at the position far from the connecting portion 110 and is not prone to deformation, by making the distance between two adjacent convex ribs close to the connecting portion 110 smaller than the distance between two adjacent convex ribs far from the connecting portion 110, the structural strength of the profile is further improved, and the stability after the profile is installed is enhanced.

[0035] In an embodiment of the present utility model, a plurality of internal ribs 120 are arranged in the cavity. The internal ribs 120 are in a sheet structure. The plurality of internal ribs 120 are arranged at intervals along the width direction of the profile body 100. The internal ribs 120 are perpendicular to the side walls of the cavity, and both sides of each internal rib 120 are correspondingly connected to the opposite side walls of the cavity. The plurality of internal ribs 120 divide the cavity into a plurality of cavity units 140. In this embodiment, the cross-section of the cavity unit 140 is rectangular. Of course, the cross-sectional shape of the cavity unit 140 is not limited to this. When the internal ribs 120 are in an arc-shaped sheet structure, the cross-sectional shape of the cavity unit 140 can also be circular, oval or other shapes.

[0036] In an embodiment of the present utility model, six internal ribs 120 are arranged in the cavity. Compared with the existing profiles, by increasing the number of internal ribs 120, the structural strength of the profile is effectively improved. Of course, the number of internal ribs 120 is not limited to this, and seven, eight or more can also be set.

[0037] In an embodiment of the present utility model, the thickness of each internal rib 120 is equal, and the internal rib 120 is integrally formed with the side wall of the cavity. The internal rib 120 is used to strengthen the profile to improve the structural strength of the profile.

[0038] In an embodiment of the present utility model, the thickness of the internal rib 120 gradually increases along the direction close to the connecting portion 110. As Figure 1 shown, connecting portions 110 are arranged on both the left and right sides of the profile body 100. A plurality of internal ribs 120 are arranged between the two connecting portions 110. A part of the plurality of internal ribs 120 is located on the left side, and the other part is located on the right side. The thickness of the internal ribs 120 on the left side gradually increases along the direction from right to left, and the thickness of the internal ribs 120 on the right side gradually increases along the direction from left to right. By making the thickness of the internal rib 120 gradually increase along the direction close to the connecting portion 110, the internal rib 120 can cooperate with the side wall of the connecting portion 110 to strengthen the structural strength of the profile body 100.

[0039] In an embodiment of the present utility model, the distance between two adjacent internal ribs 120 gradually decreases in the direction approaching the connecting portion 110. Since the greater the distance between two adjacent internal ribs 120, the lower the structural strength of the profile body 100 at this position; the smaller the distance between two adjacent internal ribs 120, the higher the structural strength of the profile body 100 at this position. As Figure 1 shown, the distance between two adjacent internal ribs 120 on the left side gradually decreases in the direction from right to left, and the distance between two adjacent internal ribs 120 on the right side gradually decreases in the direction from left to right. By reducing the distance between two adjacent internal ribs 120 approaching the connecting portion 110, the structural strength of the profile body 100 can be further improved.

[0040] In an embodiment of the present utility model, at least one end of the profile body 100 is provided with a nut fixing groove 130 for fixing a nut. Specifically, as Figure 1 shown, both ends of the profile body 100 are provided with two nut fixing grooves 130. The nut fixing grooves 130 extend along the length direction of the profile body 100, and the cross-section of the nut fixing groove 130 is trapezoidal. The width and depth of each nut fixing groove 130 are equal, which is convenient for unified processing of the nut fixing groove 130.

[0041] The following combines Figure 1 to describe a specific embodiment of the present utility model. As Figure 1 shown, the profile includes a profile body 100, and the cross-section of the profile body 100 is rectangular. The material of the profile body 100 is aluminum alloy. The interior of the profile body 100 has a cavity, and there are four connecting portions 110 on the outer side of the side wall of the cavity. Specifically, one connecting portion 110 is provided on each of the upper and lower sides of the left end of the profile body 100, and one connecting portion 110 is provided on each of the upper and lower sides of the right end of the profile body 100. In this embodiment, the connecting portion 110 is a plane. The thickness of the side wall provided with the connecting portion 110 is greater than the thickness of the side wall not provided with the connecting portion 110, and the thickness of the profile body 100 is 4 mm.

[0042] Six internal ribs 120 are arranged in the cavity. The internal ribs 120 are in sheet-like structures. The six internal ribs 120 are arranged at intervals along the width direction of the profile body 100. The internal ribs 120 are perpendicular to the side walls of the cavity. Both sides of each internal rib 120 are correspondingly connected to the opposite side walls of the cavity. The thickness of each internal rib 120 is equal. The internal ribs 120 and the side walls of the cavity are integrally formed. The six internal ribs 120 divide the cavity into seven cavity units 140. In this embodiment, the cross-section of the cavity unit 140 is rectangular. The distance between two adjacent internal ribs 120 on the left gradually decreases along the direction from right to left, and the distance between two adjacent internal ribs 120 on the right gradually decreases along the direction from left to right. Two nut fixing grooves 130 are arranged at both ends of the profile body 100. Each nut fixing groove 130 extends along the length direction of the profile body 100. The cross-section of each nut fixing groove 130 is trapezoidal. The width and depth of each nut fixing groove 130 are equal.

[0043] By making the thickness of the side wall provided with the connecting portion 110 greater than the thickness of the side wall not provided with the connecting portion 110, the structural strength of the profile connection is strengthened, and the torsional resistance is relatively strong, avoiding deformation of the profile connection after being stressed, and solving the problem that the fire truck will vibrate during driving.

[0044] The present utility model also provides a fire truck, which includes a fire truck main body and the profile described in any one of the above embodiments, and the profile is arranged on the fire truck main body.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
