Description

Technical Field

[0001] This utility model relates to the field of aircraft weighing scale technology, specifically a portable aircraft weighing scale. Background Technology

[0002] Aircraft weighing scales are devices used to measure the weight of aircraft. They are commonly used by airlines and airports to accurately measure the weight of aircraft, as the total weight of an aircraft is crucial for flight safety and performance. Aircraft weighing scales work by weighing the aircraft on the ground to determine the mass of its various parts. Depending on the weight of the aircraft, weighing scales may use different technologies, such as electronic sensors and hydraulic systems, to ensure accurate measurements.

[0003] Currently, existing aircraft weighing scales typically use auxiliary tilting guide blocks to guide the aircraft smoothly onto the weighing platform for weighing. However, while the device can perform weighing operations, it lacks portability. Consequently, when the aircraft weighing scale needs to be moved, the long tilting guide blocks can easily affect its portability, resulting in limited practicality. To address this issue, we provide a portable aircraft weighing scale that solves the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a portable aircraft weighing scale.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable aircraft weighing scale, comprising a weighing scale body, a folding mechanism provided on the outer side of the weighing scale body, the folding mechanism comprising a fixed frame, the outer surface of the fixed frame being fixedly connected to the outer surface of the weighing scale body, a first inclined guide block being movably hinged to the outer surface of the weighing scale body, a second inclined guide block being slidably connected to the inner wall of the first inclined guide block, a rotating shaft being rotatably connected to the inner wall of the fixed frame, a first bevel gear being fixedly connected to the outer surface of the rotating shaft, two second bevel gears being meshed with the outer surface of the first bevel gear, a screw being fixedly connected to the inner wall of each second bevel gear, the ends of the two screws being rotatably connected to the inner wall of the fixed frame, a pressing frame being threadedly connected to the outer surface of each screw, and the outer surface of each pressing frame being slidably connected to the inner wall of the fixed frame.

[0006] Furthermore, two positioning blocks are fixedly connected to both sides of the weighing scale body, and each positioning block has a positioning hole on its upper surface.

[0007] Furthermore, the inner wall of the first inclined guide block is threaded with two bolts, and the ends of the two bolts that are close to each other are threadedly connected to the inner wall of the second inclined guide block.

[0008] Furthermore, reinforcing blocks are fixedly connected to both sides of the fixed frame, and the front of each reinforcing block is fixedly connected to the back of the weighing scale body.

[0009] Furthermore, two displays are fixedly installed on the upper surface of the weighing scale body, and each display is electrically connected to the weighing scale body via a wire.

[0010] Furthermore, a rotating block is fixedly connected to the top of the rotating shaft, and anti-slip grooves are arranged at equal intervals on the outer surface of the rotating block.

[0011] Furthermore, each of the screws has a limiting plate rotatably connected to its outer surface, and the outer surface of each limiting plate is fixedly connected to the inner wall of the fixed frame.

[0012] Compared with existing technologies, this portable aircraft weighing scale has the following advantages:

[0013] This invention, by incorporating a folding mechanism, allows the aircraft weighing scale to be folded for transport, effectively solving the problem of existing aircraft weighing scales being inconvenient to carry due to their long inclined guide blocks. During folding, the sliding connection between the first and second inclined guide blocks allows the second inclined guide block to be inserted into the first inclined guide block. Simultaneously, because the first inclined guide block is hinged to the weighing scale, it can be folded and flipped to the top of the weighing scale. The rotating shaft drives the first bevel gear to rotate, which in turn drives the screw to rotate. The screw's threaded connection with the extrusion frame causes the extrusion frame to move. These structures work together to fix the first inclined guide block, thus facilitating the folding process. This design greatly improves the portability of the weighing scale. Compared to existing aircraft weighing scales that are inconvenient to carry, this device avoids inconvenience during transport due to its own structure, enhancing its practicality.

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0020] This embodiment provides a portable aircraft weighing scale. The device can be quickly folded and stored during the transfer of the aircraft weighing scale, improving the portability of the device during transfer.

[0021] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A portable aircraft weighing scale includes a weighing scale body 1. A folding mechanism 2 is provided on the outside of the weighing scale body 1. The folding mechanism 2 includes a fixing frame 201. Two positioning blocks 209 are fixedly connected to both sides of the weighing scale body 1. Each positioning block 209 has a positioning hole 210 on its upper surface. The positioning blocks 209 and positioning holes 210 are designed to facilitate positioning and cooperation with other equipment or structures when the weighing scale is in use. The positioning blocks 209 can accurately determine the connection position, while the positioning holes 210 can achieve precise positioning and fixation through screws or other positioning pins and other connecting parts, thereby improving the stability and accuracy of the entire weighing process.

[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The outer surface of the fixed frame 201 is fixedly connected to the outer surface of the weighing scale body 1. The outer surface of the weighing scale body 1 is movably hinged with a first inclined guide block 202. The inner wall of the first inclined guide block 202 is threaded with two bolts 212. The ends of the two bolts 212 that are close to each other are threadedly connected to the inner wall of the second inclined guide block 203. This bolt 212 connection method can effectively enhance the connection stability between the first inclined guide block 202 and the second inclined guide block 203. During the operation of the folding mechanism 2, especially when the aircraft weighing scale needs to be folded for easy carrying, the connection between the first inclined guide block 202 and the second inclined guide block 203 needs to withstand a certain force. The bolt 212 connection can prevent them from loosening or misaligning, ensuring the normal operation of the folding mechanism 2.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The inner wall of the first inclined guide block 202 is slidably connected to the second inclined guide block 203, and the inner wall of the fixed frame 201 is rotatably connected to the rotating shaft 204. Both sides of the fixed frame 201 are fixedly connected to the reinforcing blocks 211. The front of each reinforcing block 211 is fixedly connected to the back of the weighing scale body 1. The presence of the reinforcing blocks 211 significantly improves the structural strength of the connection between the fixed frame 201 and the weighing scale body 1. During the aircraft weighing process, the weighing scale needs to bear the weight of the aircraft, which may generate large stress. The reinforcing blocks 211 can effectively disperse these stresses and prevent damage to the connection between the fixed frame 201 and the weighing scale body 1, ensuring the normal use of the weighing scale.

[0024] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A first bevel gear 206 is fixedly connected to the outer surface of the rotating shaft 204. Two second bevel gears 207 are meshed with the outer surface of the first bevel gear 206. Two displays 213 are fixedly installed on the upper surface of the weighing scale body 1. Each display 213 is electrically connected to the weighing scale body 1 through a wire. The display 213 can provide more information or display different data, so that the operator can have a more comprehensive understanding of the aircraft's weighing information and improve the convenience and accuracy of operation.

[0025] Reference Figure 2 , Figure 3 and Figure 4Each second bevel gear 207 has a screw 208 fixedly connected to its inner wall. The ends of the two screws 208 that are far apart from each other are rotatably connected to the inner wall of the fixed frame 201. A rotating block 215 is fixedly connected to the top of the rotating shaft 204. The outer surface of the rotating block 215 is provided with anti-slip grooves 216 arranged at equal intervals. The rotating block 215 is designed to facilitate the operation of the rotating shaft 204 by the operator. The presence of the anti-slip grooves 216 further improves the convenience of operation. When the operator rotates the rotating block 215, his / her fingers can better grip the rotating block 215 to prevent slippage during operation, thereby enabling more precise control of the rotation of the rotating shaft 204.

[0026] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 Each screw 208 has a threaded connection to an extrusion frame 205 on its outer surface. The outer surface of each extrusion frame 205 is slidably connected to the inner wall of the fixed frame 201. Each screw 208 has a rotatably connected limit plate 214 on its outer surface. The outer surface of each limit plate 214 is fixedly connected to the inner wall of the fixed frame 201. The function of the limit plate 214 is to ensure the stability of the screw 208 during rotation. During the operation of the folding mechanism 2, the rotation of the screw 208 is crucial for the movement of the extrusion frame 205. The limit plate 214 can restrict the axial displacement of the screw 208, prevent the screw 208 from shaking or deviating from its normal rotation axis, and ensure that the screw 208 can stably drive the extrusion frame 205 to move, thereby ensuring the normal operation of the folding mechanism 2.

[0027] Working principle: In use, the operator first connects the weighing scale body 1 and the display screen 213 to the power supply to ensure a stable power supply. Then, multiple weighing scales are prepared and placed at the various tire locations on the bottom of the aircraft. The aircraft is then guided onto the weighing scale body 1 by the first inclined guide block 202 and the second inclined guide block 203 for weighing. The display screen 213 shows the weighing data. When the device needs to be folded for transport, the operator removes the bolt 212 and pushes the second inclined guide block 203 into the first inclined guide block 202. The removed bolt 212 is then used to secure the two guide blocks through the rear hole. Subsequently, due to the first inclined guide block 202 and the weighing scale... The main body 1 is hinged and can be folded and flipped to the top of the weighing scale body 1. Then, the rotating shaft 204 is rotated. The rotating block 215 at the top of the rotating shaft 204 facilitates operation. The anti-slip groove 216 increases friction. The first bevel gear 206 on the rotating shaft 204 meshes with two second bevel gears 207. Each second bevel gear 207 drives the screw 208 to rotate. The two ends of the screw 208 are rotatably connected to the fixed frame 201 and are limited in the middle by the limiting plate 214. When the screw 208 rotates, the threaded compression frame 205 slides in the fixed frame 201 until the plugs of the two compression frames 205 can be inserted into the first inclined guide block 202 for limiting, thereby completing the folding work and making it convenient for staff to carry and transport the device.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
