DETAILED DESCRIPTION
[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0018] like Figure 1 - Figure 3As shown, a fixed ladder frame for the roof of a fire truck includes two mounting brackets 1. The ends of the two mounting brackets 1 that are close to each other are slidably mounted with rollers 14. The rollers 14 are designed to be made of nylon material to prevent the ladder from colliding with and wearing the ladder during the process of taking and placing. A wheel axle 15 is commonly provided between the two rollers 14. By adjusting the horizontal heights of the two rollers 14, the device can be used for ladders of different thicknesses when in use. The lower ends of the two mounting brackets 1 are fixed with ladder frame fixing supports 13 that are convenient for placing the fixed ladder frames. When in use, the device can use the threaded holes provided in the ladder frame fixing supports 13 to fix the ladder frame fixing supports 13 on the roof of the fire truck to prevent the fixed ladder frame from sliding or falling when the vehicle is driving, thereby causing safety hazards and reducing the stability of the device when in use. A fixed baffle hinge 2 is fixed to the upper end of the left mounting bracket 1.
[0019] Specifically, a concave-shaped lower bracket 9 is rotatably installed on the upper end of the fixed baffle hinge 2. Through the rotatable connection between the fixed baffle hinge 2 and the lower bracket 9, the device can allow the ladder to be placed between the lower bracket 9 and the wheel axle 15 when in use, to prevent the ladder from moving in the vertical direction. At the same time, the design of two mounting brackets 1 can also limit the ladder in the horizontal direction. The front end of the mounting bracket 1 on the right side is fixed with a buckle 10 for fixing the lower bracket 9, so that the lower bracket 9 can be fixedly connected relative to the mounting bracket 1 when the fixed ladder frame is fixing the ladder to prevent the ladder from detaching. At the same time, due to the design of the buckle 10, it is also convenient to take and put the ladder. Vertically arranged card plates 7 are fixed at the front and rear ends of the lower bracket 9. The card plates 7 are used to fix the crossbeam of the ladder to prevent the ladder from moving forward or backward, so that the fixed ladder frame can better fix the ladder when in use.
[0020] Furthermore, an upper bracket 6 is rotatably installed on the upper end of the protrusion on the left side of the lower bracket 9 through a movable hinge 3. The upper bracket 6 is rotatably connected to the lower bracket 9, so that the ladder can be placed between the upper bracket 6 and the lower bracket 9 when the device is in use, preventing the ladder from moving in the vertical direction. At the same time, since the lower bracket 9 adopts a concave design, the two protrusions of the lower bracket 9 can limit the ladder in the horizontal direction. At the same time, the clamping plate 7 can also fix the crossbeam of the ladder to prevent the ladder from moving forward or backward, so that the fixed ladder frame can better fix the ladder when in use.
[0021] In addition, a buckle 10 for fixing the upper bracket 6 is also fixed to the front end of the protrusion on the right side of the lower bracket 9, so that the upper bracket 6 can be fixedly connected relative to the lower bracket 9 when the ladder is fixed to prevent the ladder from detaching. At the same time, due to the design of the buckle 10, it is also convenient to take and put the ladder. Round rubber blocks 5 are fixed on the left and right sides of the lower end of the upper bracket 6, and an L-shaped plate 4 is also fixed at the corner of the lower bracket 9. Round rubber blocks 5 are also fixed on the inner side of the L-shaped plate 4. Multiple round rubber blocks 5 can prevent collision and wear during the ladder taking and putting. An end cover plate 8 is fixed on the end of the upper bracket 6 away from the movable hinge 3, and a single-bar ladder fixing seat 11 and a fire hook fixing seat 12 are fixed to the right end of the right-side mounting bracket 1 from top to bottom. The single-bar ladder fixing seat 11 is used for placing the single-bar ladder, and the fire hook fixing seat 12 is used for placing the fire hook.
[0022] The specific implementation of this embodiment is as follows: when the fixed ladder frame is in use, the two fixed ladder frame bodies are first fixed on the roof of the fire truck, and the two fixed ladder frames are arranged on the left and right, so that the fire truck will not be too wide when traveling, thereby being safer;
[0023] like Figure 4 As shown, when placing a larger ladder, open the buckle 10 located below, and then rotate the lower bracket 9 so that the fire ladder is stuck between the two mounting brackets 1, and then rotate the lower bracket 9 to a horizontal state, and then use the buckle 10 to fix the lower bracket 9. When a smaller ladder needs to be placed, open the buckle 10 located below, and then rotate the upper bracket 6, and then let the fire ladder be stuck in the two raised parts of the lower bracket 9, and then use the buckle 10 to fix the upper bracket 6. At the same time, the fixed ladder frame adopts the design of a single-bar ladder fixing seat 11 and a fire hook fixing seat 12, which can also facilitate the placement of the single-bar ladder and the fire hook.
[0024] It should be noted that the specific installation method, circuit connection method and control method of the movable hinge 3, the round rubber block 5 and the buckle 10 in the present invention are all conventional designs and will not be elaborated in detail in the present invention.
[0025] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
