DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0029] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model 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, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0030] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0031] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] As mentioned in the background art, although loading the rubber boat on the roof of the vehicle saves the space in the vehicle compartment, the loading or unloading operation is cumbersome, which prolongs the rescue time and affects the rescue efficiency. In addition, there is a safety hazard of slipping and hitting people in the above process.

[0033] In order to improve the above problems, the utility model proposes a flipping mechanism, which can carry and accommodate equipment, and a single person can complete the loading and disassembly of the equipment, so as to shorten the rescue time and improve the rescue efficiency during fire rescue.

[0034] Figure 1 This is a schematic diagram of the flip mechanism 10 provided in the embodiment of the utility model in a closed state. Figure 2 This is a schematic diagram of the flip mechanism 10 provided in the embodiment of the utility model in an open state. Figure 3The embodiment of the utility model provides Figure 1 Please refer to the enlarged schematic diagram of the structure at A in the middle. Figures 1 to 3 The utility model provides a flipping mechanism 10 , which includes a fixing frame 110 , a flipping frame 130 , a bearing assembly 300 and a transmission member 510 .

[0035] Among them, the fixed frame 110 is used to connect with the top of the vehicle body, and the fixed frame 110 is rotatably connected to the flip frame 130; the supporting assembly 300 is slidably connected to the flip frame 130, and the supporting assembly 300 is used to store equipment; the transmission member 510 is connected to the supporting assembly 300, and the transmission member 510 is used to drive the supporting assembly 300 to slide.

[0036] Based on the above arrangement, when firefighters need to load or unload firefighting equipment, they pull one end of the transmission member 510 that naturally hangs down along the vehicle body, and drive the bearing assembly 300 that can accommodate firefighting equipment to slide through the transmission member 510. After pulling to the ideal distance, the flip frame 130 is rotated relative to the fixed frame 110 by manual or automatic control and kept tilted, so as to drive the bearing assembly 300 to tilt, thereby facilitating the workers to install or unload firefighting equipment.

[0037] It should be noted that the sliding direction of the bearing assembly 300 relative to the flip frame 130 is Figure 1 The direction indicated by the arrow in the middle is actually the direction of travel of the vehicle. In addition, it should be noted that the firefighting equipment involved in the above process can be not only set as a rubber boat, but also as a variety of heavier firefighting equipment such as a water pipe or a ladder.

[0038] Figure 4 The embodiment of the utility model provides Figure 2 Please refer to the enlarged schematic diagram of the structure at B in the middle again. Figure 4 In order to facilitate switching the opening and closing states between the opposite surfaces of the fixed frame 110 and the flip frame 130, a power unit 900 is provided between the fixed frame 110 and the flip frame 130. The flip mechanism 10 further includes the power unit 900. One end of the power unit 900 is connected to the fixed frame 110, and the other end is connected to the flip frame 130. Specifically, the power unit 900 may be provided with a gas spring or a hydraulic cylinder.

[0039] Based on this, firefighters can load or unload more conveniently and labor-savingly, thereby shortening the rescue time and improving the rescue efficiency. In addition, it can be understood that in other implementations, other telescopic rod structures can also be selected to realize the opening and closing between the fixed frame 110 and the flip frame 130, such as a pneumatic cylinder, a hydraulic cylinder or a pneumatic cylinder.

[0040] Please refer again Figure 1 and Figure 2In order to improve the smoothness of the bearing assembly 300 during the sliding process, the flip mechanism 10 also includes a guide frame 700, which is used to connect to the top of the vehicle body, and the guide frame 700 and the fixed frame 110 are arranged along the sliding direction of the bearing assembly 300, and the guide frame 700 and the bearing assembly 300 are slidably matched.

[0041] Figure 5 Another schematic diagram of the flip mechanism 10 provided in the embodiment of the utility model when it is in a closed state is shown in FIG. Figure 5 and Figure 2 In some embodiments, the number of guide frames 700 is at least two, and at least two guide frames 700 are arranged at intervals along the sliding direction of the bearing assembly 300; the flip mechanism 10 further includes a clamping member 530, which is arranged at one end of the bearing assembly 300 away from the transmission member 510, and the guide frame 700 farthest from the fixing frame 110 is provided with a limiting rod 710 cooperating with the clamping member 530.

[0042] Based on this, when the firefighter resets the bearing assembly 300 after unloading or loading, the bearing assembly 300 slides along the guide frame 700 until the clamping member 530 thereon cooperates with the limiting rod 710 to fix the bearing assembly 300. The above arrangement can prevent the bearing assembly 300 from slipping during the driving of the vehicle, thereby causing damage to the firefighting equipment or injuries to personnel.

[0043] Figure 6 Another schematic diagram of the flip mechanism 10 provided in the embodiment of the utility model when it is in the open state, please refer to Figure 5 In some embodiments, the bearing assembly 300 includes a bearing frame 310 and a blocking structure 320 . The bearing frame 310 is slidably connected to the flip frame 130 . The blocking structure 320 is connected to a side of the bearing frame 310 close to the flip frame 130 .

[0044] It is understandable that the load-bearing frame 310 is slidably connected to the flip frame 130 and the guide frame 700 mentioned above. When the firefighter pulls the transmission member 510, the load-bearing frame 310 slides accordingly until the blocking structure 320 disposed on the load-bearing frame 310 and the flip frame 130 are abutted against each other, that is, the firefighter pulls the load-bearing frame 310 to the ideal distance, and the load-bearing frame 310 stops sliding.

[0045] Based on this, the firefighters can adjust where the blocking structure 320 is connected to the load-bearing frame 310 according to their own habits, so as to adjust the sliding distance of the load-bearing frame 310. It should be emphasized that it is sufficient to ensure that the blocking structure 320 and the turnover frame 130 will not collide.

[0046] Please refer again Figure 4 In order to prevent the blocking structure 320 from affecting the structural performance of the flip frame 130 after the impact, the blocking structure 320 includes a fixed part 321, a movable part 323 and an elastic part 325. The fixed part 321 is connected to the supporting frame 310, the movable part 323 is slidably connected to the fixed part 321, and the elastic part 325 is sleeved on the movable part 323, and one end of the elastic part 325 abuts against the fixed part 321, and the other end abuts against the movable part 323.

[0047] When the blocking structure 320 collides with the flip frame 130, the movable member 323 first contacts the flip frame 130 and moves along the direction of the impact force, converting part of the impact force into kinetic energy. In addition, during this process, the elastic member 325 sleeved on the movable member 323 is deformed to dissipate another part of the impact force.

[0048] Based on the above, the blocking structure 320 buffers and dissipates the impact force generated during the collision, effectively avoiding the situation where the flip frame 130 is damaged and its rotation relative to the fixed frame 110 is affected when the collision is too strong, or the flip frame 130 cannot successfully block the limit blocking structure 320, causing the load-bearing frame 310 to slip and cause an accident during unloading or loading.

[0049] Please refer again Figure 3 In order to prevent the load-bearing assembly 300 from loosening during the operation of the vehicle, the flip frame 130 is provided with a limit column 131. The load-bearing assembly 300 also includes a locking member 330. The transmission member 510 is rotatably connected to the load-bearing frame 310. One end of the locking member 330 is connected to the transmission member 510, and the other end is locked or unlocked with the limit column 131.

[0050] It is understandable that, since the transmission member 510 is rotatably connected to the bearing frame 310, the locking member 330 is connected to the transmission member 510. Therefore, when the firefighter rotates the transmission member 510, the locking member 330 rotates together with the transmission member 510, and drives the other end to be locked or unlocked with the limit column 131, thereby achieving the locking or unlocking of the bearing assembly 300. In detail, as Figure 3 As shown, when the transmission member 510 rotates counterclockwise, the locking member 330 and the limiting column 131 are unlocked; when the transmission member 510 rotates clockwise, the locking member 330 and the limiting column 131 are locked.

[0051] Please refer again Figure 5 and Figure 6 In order to facilitate the accommodation of fire-fighting equipment, the bearing assembly 300 also includes a first protective frame 340 and a second protective frame 350. The first protective frame 340 and the second protective frame 350 are both connected to the bearing frame 310, and the first protective frame 340 and the second protective frame 350 together surround and form an accommodating space.

[0052] It should be noted that the first protective frame 340 and / or the second protective frame 350 are made of stainless steel pipes to avoid abrasion during the loading or unloading of the fire-fighting equipment. In particular, when the fire-fighting equipment is a rubber boat, air leakage caused by friction in the rubber boat can be avoided. Based on this, the safety and reliability of the vehicle driving process are guaranteed.

[0053] In order to solve the problem of single accommodating space compatibility, the first protective frame 340 is slidably connected to the bearing assembly 300 through the first fixed pipe clamp 610, and the second protective frame 350 is slidably connected to the first protective frame 340 through the second fixed pipe clamp 630.

[0054] Based on this, when it is necessary to be compatible with fire-fighting equipment of different specifications, the size of the accommodating space can be adaptively adjusted by relative sliding of the first protective frame 340 and the second protective frame 350. In addition, it should be noted that the first fixed pipe clamp 610 is a single U straight fixed pipe clamp, and the second fixed clamp is a double U cross fixed pipe clamp.

[0055] Such as 5 and Figure 6 As shown, the second protection frame 350 includes two guardrails arranged at intervals along a direction perpendicular to the sliding direction of the load-bearing frame 310 to achieve the position limitation of the two sides of the fire-fighting device. Similarly, the end of the first protection frame 340 away from the transmission member 510 is also provided with a guardrail to achieve the position limitation in the travel direction of the fire-fighting device. Optionally, a detachable guardrail can be provided at the end of the first protection frame 340 close to the transmission member 510 to facilitate the position limitation of the fire-fighting device while ensuring that loading or unloading is simple and labor-saving.

[0056] Taking this embodiment as an example, the operation process and operation principle of the flip mechanism 10 provided by the utility model are as follows:

[0057] When unloading the firefighting equipment, the firefighter rotates the transmission member 510 counterclockwise to unlock the locking member 330 and the limiting column 131. After that, the firefighter pulls the transmission member 510 and pulls the supporting frame 310 to slide relative to the flip frame 130 and the guide frame 700 until the blocking structure 320 collides with the flip frame 130 to limit the position.

[0058] Afterwards, the power unit 900 is manually turned on and expanded to the maximum position, so that the flip frame 130 rotates relative to the fixed frame 110 and remains tilted, thereby driving the supporting frame 310 and the first protective frame 340 and the second protective frame 350 thereon to tilt. At this time, the firefighters can take out the fire-fighting equipment from the accommodating space and complete the disassembly of the fire-fighting equipment.

[0059] After the above process is completed, the power unit 900 is reset, and the flip frame 130 is reset at the same time. The firefighter pushes the support frame to reset through the transmission member 510 until the clamping member 530 is connected to the limit rod 710 provided on the guide frame 700. Finally, the firefighter rotates the transmission member 510 clockwise, so that the locking member 330 is locked with the limit column 131, and the bearing assembly 300 is locked with the flip frame 130.

[0060] In addition, since the loading process of fire-fighting equipment is similar to the above process, it will not be repeated here.

[0061] In summary, the utility model provides a flipping mechanism 10, which includes a fixed frame 110, a flipping frame 130, a bearing assembly 300 and a transmission member 510. Based on the above arrangement, when firefighters need to load or unload firefighting equipment, they pull one end of the transmission member 510 that naturally hangs down along the vehicle body, and at the same time drive the bearing assembly 300 that can accommodate firefighting equipment to slide through the transmission member 510. After being pulled to the ideal distance, the flipping frame 130 is rotated and kept tilted relative to the fixed frame 110 by manual or automatic control, so as to drive the bearing assembly 300 to tilt, thereby facilitating the staff to install or unload firefighting equipment. Therefore, the flipping mechanism 10 improves the rescue efficiency and shortens the rescue time.

[0062] In addition, the utility model also provides a fire truck, which includes the above-mentioned flipping mechanism 10, and thus has the advantages of being able to carry and accommodate equipment, and a single person can complete the loading and disassembly of the equipment, so as to shorten the rescue time and improve the rescue efficiency during fire rescue.

[0063] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
