[0001] This utility model relates to the field of aviation technology, and in particular to a dedicated grounding device for aviation ground mobile equipment. Background Technology
[0002] In the aviation industry, ground mobile equipment such as towing vehicles, power supply vehicles, and air conditioning vehicles play a vital role in the daily operation of airports. While providing necessary services to aircraft, these devices also involve a large number of electrical connections and operations. Due to the complex aviation ground environment and the presence of various potential electrical hazards such as lightning and static electricity, ensuring the electrical safety of these devices is of paramount importance.
[0003] A Chinese patent discloses a dedicated grounding device for aviation ground mobile equipment (authorization announcement number CN207818957U). This patented technology can provide separate grounding protection for aviation ground mobile equipment, with good standardization and reliability, and can meet the grounding resistance requirements.
[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: Most existing grounding devices adopt simple plug-in fixed grounding wires. However, in actual use, these fixing methods are prone to loosening or falling off due to improper operation, environmental factors such as vibration and wind, or wear caused by long-term use. The falling off of the grounding wire will not only affect the normal operation of the equipment, but may also cause electrical safety hazards, posing a threat to personnel and equipment. Utility Model Content
[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that ground mobile equipment needs to be moved and docked frequently, and the connection and disconnection of the grounding wire is frequent, which can easily cause it to fall off. To this end, we propose a special grounding device for aviation ground mobile equipment.
[0006] To achieve the above objectives, this application adopts the following technical solution: a grounding device for aviation ground mobile equipment, comprising a grounding device body, a wiring block installed on one side of the grounding device body, a rotating post rotatably connected inside the wiring block, a grounding wire disposed inside the rotating post, adjustment grooves opened at both ends of the rotating post, adjustment blocks slidably connected inside the adjustment grooves, a plug fixedly connected to the side of the adjustment block near the inside of the adjustment groove, arc blocks fixedly connected to both ends inside the wiring block, and insertion holes opened at both ends of the grounding wire.
[0007] Preferably, the wiring block has two annular grooves inside, and the rotating post has two annular blocks fixedly connected to its surface.
[0008] Preferably, a silicone pad is installed inside the terminal block on the side near the grounding wire.
[0009] Preferably, the size of the plug is adapted to the size of the socket, and the surface of the plug is inserted into the interior of the socket.
[0010] Preferably, screws are provided on both sides of the wiring block, and screw holes are provided on both sides of the rotating column.
[0011] Preferably, a storage spring is fixedly connected to the side of the adjusting block near the insert block, and the side of the storage spring away from the adjusting block is fixedly connected to the inside of the adjusting groove.
[0012] Preferably, the adjusting groove has sliding grooves on both sides, and the adjusting block has sliders fixedly connected to both sides, with the surface of the sliding groove and the interior of the slider being slidably connected.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] In this invention, the worker inserts the grounding wire into the inside of the rotating column, aligns the plug with the socket, and rotates the rotating column to move it. The rotating column drives the adjusting block and the plug to rotate, so that the adjusting block contacts the thicker end of the arc block. The arc block gradually squeezes the adjusting block, causing the plug to be inserted into the socket to limit the grounding wire. The above setting prevents the grounding wire from falling off during operation. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0023] Reference Figure 1 - Figure 6 As shown, this utility model provides a technical solution: a special grounding device for aviation ground mobile equipment, including a grounding device body 1. A wiring block 2 is installed on one side of the grounding device body 1. A rotating post 3 is rotatably connected inside the wiring block 2. A grounding wire 4 is provided inside the rotating post 3. Adjustment grooves 5 are opened at both ends of the rotating post 3. Adjustment blocks 6 are slidably connected inside the adjustment grooves 5. A plug block 7 is fixedly connected to the side of the adjustment block 6 near the inside of the adjustment groove 5. Arc blocks 8 are fixedly connected to both ends inside the wiring block 2. Socket holes 9 are opened at both ends of the grounding wire 4. The operator inserts the grounding wire 4 into the inside of the rotating post 3, aligns the plug block 7 with the socket hole 9, and rotates the rotating post 3 to move it. The rotating post 3 drives the adjustment block 6 and the plug block 7 to rotate, so that the adjustment block 6 contacts the thicker end of the arc block 8. The arc block 8 gradually squeezes the adjustment block 6, so that the plug block 7 is inserted into the socket hole 9 to limit the grounding wire 4. The above setting prevents the grounding wire 4 from falling off during operation.
[0024] Reference Figure 3 As shown in this embodiment: the wiring block 2 has two annular grooves 10 inside, and both are located inside the wiring block 2. The rotating column 3 has two annular blocks 11 fixedly connected to its surface. When the operator rotates the rotating column 3, the rotating column 3 drives the annular blocks 11 to rotate and slide inside the annular grooves 10. Through the above settings, the entire device is more stable during use, reducing shaking and noise. At the same time, the rotation and sliding design of the annular blocks 11 inside the annular grooves 10 can also effectively reduce frictional loss and extend the service life of the device.
[0025] Reference Figure 3 As shown in this embodiment: a silicone pad 12 is installed inside the terminal block 2 on the side near the grounding wire 4. By installing the silicone pad 12 inside the terminal block 2 on the side near the grounding wire 4, the grounding wire 4 is well protected, avoiding direct contact between the grounding wire 4 and the terminal block 2, reducing friction and wear, and effectively extending the service life of the grounding wire 4. At the same time, the silicone pad 12 also has good insulation properties, further improving the safety of the entire grounding device.
[0026] Reference Figure 4 and Figure 5As shown in this embodiment: the size of the plug 7 is adapted to the size of the socket 9, and the surface of the plug 7 is inserted into the interior of the socket 9. By adapting the size of the plug 7 to the size of the socket 9, the plug 7 can be stably inserted into the interior of the socket 9, thereby increasing the structural stability of the entire device. At the same time, the insertion design between the plug 7 and the socket 9 can effectively reduce loosening or falling off caused by vibration or external force, thereby ensuring the safety and reliability of the grounding device.
[0027] Reference Figure 3 and Figure 4 As shown in this embodiment: both sides of the wiring block 2 are provided with screws 13, and both sides of the rotating post 3 are provided with screw holes 14. Through the arrangement between the screws 13 and the screw holes 14, after the operator inserts the screws 13 into the screw holes 14, the position of the rotating post 3 is fixed, avoiding the rotating post 3 from shaking inside the wiring block 2 and causing the limit between the plug block 7 and the plug hole 9 to be unstable.
[0028] Reference Figure 4 As shown in this embodiment: a storage spring 15 is fixedly connected to the side of the adjusting block 6 near the insert block 7, and the side of the storage spring 15 away from the adjusting block 6 is fixedly connected to the inside of the adjusting groove 5. When the arc block 8 gradually presses the adjusting block 6, the adjusting block 6 compresses the storage spring 15 to store force, and drives the insert block 7 to be inserted into the socket 9 for fixation. When the worker cancels the contact between the arc block 8 and the adjusting block 6, the insert block 7 will automatically pop out of the socket 9 under the action of the rebound force of the storage spring 15, which is convenient for the worker to quickly disassemble and reassemble.
[0029] Reference Figure 4 As shown in this embodiment: Sliding grooves 17 are provided on both sides of the inner side of the adjusting groove 5, and sliders 16 are fixedly connected to both sides of the adjusting block 6. The surface of the sliding groove 17 is slidably connected to the interior of the slider 16. When the operator moves the adjusting block 6, the adjusting block 6 drives the sliding groove 17 to slide inside the slider 16. Through the above setting, the stability of the adjusting block 6 during movement can be effectively improved, preventing the adjusting block 6 from shaking or shifting during movement, thereby improving the safety and reliability of the entire grounding device. At the same time, this sliding connection method can also reduce the frictional resistance of the adjusting block 6 during movement, making the movement of the adjusting block 6 smoother and further improving the operating efficiency.
[0030] Working principle: The operator inserts the grounding wire 4 into the rotating column 3, aligns the insert block 7 with the socket 9, and rotates the rotating column 3. The rotating column 3 drives the adjusting block 6 and the insert block 7 to rotate, so that the adjusting block 6 contacts the thicker end of the arc block 8. The arc block 8 gradually squeezes the adjusting block 6, causing the insert block 7 to be inserted into the socket 9, thus limiting the grounding wire 4. This setting prevents the grounding wire 4 from falling off during operation. When the operator rotates the rotating column 3, the rotating column 3 drives the ring block 11 to rotate and slide inside the ring groove 10. This setting makes the entire device more stable during use, reducing shaking and noise. At the same time, the ring block 11 rotates and slides within the ring groove 10. The rotating sliding design inside the slot 10 effectively reduces frictional loss and extends the service life of the device. The silicone pad 12 installed inside the connector block 2 near the grounding wire 4 provides excellent protection for the grounding wire 4, preventing direct contact between the grounding wire 4 and the connector block 2, reducing friction and wear, and effectively extending the service life of the grounding wire 4. Simultaneously, the silicone pad 12 also has good insulation properties, further improving the safety of the entire grounding device. The matching size of the plug 7 with the socket 9 allows the plug 7 to be stably inserted into the socket 9, thereby increasing the structural stability of the entire device. Meanwhile, the insertion design between the plug 7 and the socket 9 effectively reduces loosening or detachment caused by vibration or external force, thus ensuring the safety and reliability of the grounding device. Through the arrangement between the screw 13 and the screw hole 14, after the operator inserts the screw 13 into the screw hole 14, the position of the rotating post 3 is fixed, preventing the rotating post 3 from shaking inside the terminal block 2 and causing instability in the limit position between the plug 7 and the socket 9. When the arc block 8 gradually presses against the adjusting block 6, the adjusting block 6 compresses the energy storage spring 15 to store energy, and drives the plug 7 to be inserted into the socket 9 for fixation. When the operator closes the contact between the arc block 8 and the adjusting block 6... When canceled, the plug 7 will automatically pop out of the socket 9 under the action of the rebound force of the storage spring 15, which is convenient for the staff to quickly disassemble and reassemble. When the staff operates the adjusting block 6 to move, the adjusting block 6 drives the slide groove 17 to slide inside the slider 16. Through the above settings, the stability of the adjusting block 6 during the movement can be effectively improved, preventing the adjusting block 6 from shaking or deviating during the movement, thereby improving the safety and reliability of the entire grounding device. At the same time, this sliding connection method can also reduce the frictional resistance of the adjusting block 6 during the movement, making the movement of the adjusting block 6 smoother and further improving the operating efficiency.
