Technical Field
[0001] This utility model belongs to the field of power supply testing technology, and specifically relates to an aircraft power supply testing device. Background Technology
[0002] Traditional aircraft power testing equipment typically requires movement to a designated location and securing it during use to ensure stability and safety. This traditional method relies on multiple casters mounted on the bottom of the equipment, each with an independent brake. During operation, the operator must brake each caster individually by foot to lock it in place. After testing, the brakes must be released one by one to move the equipment.
[0003] This fixing method is cumbersome and inefficient. Since each caster needs to be braked and released individually, it greatly reduces work efficiency, especially when the equipment needs to be moved and fixed frequently. Utility Model Content
[0004] The purpose of this invention is to provide an aircraft power supply testing device to solve the problems mentioned in the background art.
[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:
[0006] An aircraft power supply testing device includes a housing with a testing equipment assembly installed inside. A control panel electrically connected to the testing equipment assembly is fixed to the front of the housing. Four casters are evenly installed on the bottom of the housing. A handrail is installed on the left side of the housing. Four short hydraulic cylinders are evenly and vertically installed on the bottom of the housing, with the output ends of the short hydraulic cylinders pointing vertically downwards. A cavity is provided on the front of the housing, and a foot pedal mechanism is vertically installed inside the cavity. The foot pedal mechanism includes two sliding rods distributed front to back and fixed to the housing. A slider is slidably installed on the upper side of the sliding rods, and a foot pedal is fixed on the lower side of the slider. A long hydraulic cylinder, connected to the pipelines of the four short hydraulic cylinders, is vertically installed inside the cavity. The diameter of the long hydraulic cylinder is smaller than that of the short hydraulic cylinders, and the input end of the long hydraulic cylinder is drivenly connected to the slider. A reset component for controlling the foot pedal reset and a fixing component for fixing the position of the slider are also installed inside the cavity.
[0007] The reset assembly includes two secondary slide rods distributed front to back and located to the right of the slide rod. A secondary slider slides up and down on the upper side of the secondary slide rods, and a secondary pedal is fixed on the lower side of the secondary slider. A support frame fixed to the housing is installed between the slide rod and the secondary slide rods. Pulleys are rotatably connected to both the upper and lower sides of the support frame. A steel cable is connected between the two pulleys for transmission. The slider and the secondary slider are evenly fixedly connected to the steel cable.
[0008] The fixing assembly includes a right-angled trapezoidal block fixed to the slider. The right-angled trapezoidal block is located behind the slider with its inclined surface facing the lower rear. A support rod fixed to the housing is installed on the rear side of the right-angled trapezoidal block. Two vertically distributed and slidably connected sliding columns are installed on the upper side of the support rod. A locking block is fixed on the front side of the sliding column. Multiple locking slots matching the right-angled trapezoidal block are evenly opened on the upper side of the locking block. A tension spring is connected between the locking block and the support rod. A small pedal is hinged to the upper side of the secondary pedal. A pull block is fixed to the upper side of the small pedal. A conduit is connected to the rear side of the secondary pedal and the rear side of the support rod. A pull wire is slidably installed inside the conduit. One end of the pull wire is fixedly connected to the pull block, and the other end is drivenly connected to the locking block.
[0009] A rubber block is installed at the bottom of the output end of the short hydraulic cylinder.
[0010] A light shield is fixed to the upper side of the control panel.
[0011] The combination of a sliding rod, foot pedal, slider, and short cylinders connected via long cylinders and pipelines allows the operator to control the equipment's fixation with a simple foot pedal action. This fixing method is simple to operate and highly efficient; a single pedal press is sufficient to brake and release the equipment. This significantly improves work efficiency, especially when the equipment needs frequent movement and fixation. The design of the four short cylinders having a larger diameter than the long cylinders ensures more stable equipment fixation and makes foot pedal operation easier and less strenuous, further enhancing the equipment's ease of use. The combination of pulleys and steel cables allows the foot pedal to be depressed, lifting the input end of the long cylinder. Under atmospheric pressure, the output end of the short cylinder returns to its original position. This design makes the foot pedal mechanism... After release, the device can be reset by foot control, avoiding the need for manual reset by the operator, thus improving equipment safety and ease of use. The design of right-angled trapezoidal blocks, locking blocks, and slots allows the slider to be fixed in different positions, increasing the adaptability and flexibility of the equipment and preventing accidental extension and retraction of the short cylinder caused by slider movement, thereby improving the stability of the equipment. At the same time, it also makes the structure of the fixing components simple and reliable, reducing its maintenance costs. The bottom of the output end of the short cylinder is equipped with a rubber block, which can effectively protect the output end of the short cylinder and increase its friction with the ground, thereby further increasing the stability of the equipment when fixed. The sunshade on the upper side of the control panel is used to prevent direct sunlight, making it easier for operators to observe the equipment's test data, further improving the ease of use of the equipment.

[0020] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0021] like Figure 1-6 As shown, an aircraft power supply testing device includes a housing 1, a testing equipment assembly 2 installed inside the housing 1, a control panel 3 electrically connected to the testing equipment assembly 2 fixed to the front of the housing 1, four casters 4 evenly installed at the bottom of the housing 1, a handrail 5 installed on the left side of the housing 1, four short hydraulic cylinders 6 evenly and vertically installed at the bottom of the housing, with the output ends of the short hydraulic cylinders 6 pointing vertically downwards, a cavity 7 provided at the front of the housing 1, a foot pedal mechanism vertically installed inside the cavity 7, the foot pedal mechanism including two sliding rods 8 distributed front to back and fixed to the housing 1, a slider 9 slidably installed on the upper side of the sliding rods 8, a foot pedal 10 fixed on the lower side of the slider 9, a long hydraulic cylinder 11 vertically installed inside the cavity 7, which is connected to the pipelines of the four short hydraulic cylinders 6 respectively, the diameter of the long hydraulic cylinder 11 is smaller than the diameter of the short hydraulic cylinders 6, the input end of the long hydraulic cylinder 11 is connected to the slider 9 for transmission, a reset component for controlling the reset of the foot pedal 10 and a fixing component for fixing the position of the slider 9 are also installed inside the cavity 7.
[0022] The casters 4 and handles 5 at the bottom of the housing 1 allow the equipment to be easily moved between different locations. The control panel 3 is used to adjust and display the data of the testing equipment assembly 2. When the equipment needs to be fixed, the operator steps down on the foot pedal 10, and then the fixing component fixes the position of the slider 9. At this time, the slider 9 will drive the input end of the long oil cylinder 11 to move downward, squeezing the oil inside the long oil cylinder 11 into the four short oil cylinders 6. The output end of the short oil cylinders 6 extends vertically downward to lift the entire housing 1, thus fixing it. After the equipment is used, the reset component resets the short oil cylinders 6.
[0023] The combination of the slide bar 8, foot pedal 10, slider 9, and short cylinder 6 connected by the long cylinder 11 and pipelines allows the operator to control the fixing of the equipment by simply pressing the foot pedal 10. This fixing method is simple to operate and highly efficient. Only one press of the foot pedal 10 is needed to brake and release the equipment. Especially when the equipment needs to be moved and fixed frequently, it will greatly improve work efficiency. The design of the diameter of the four short cylinders 6 being larger than the diameter of the long cylinder 11 makes the equipment fixing more stable and also makes the operation of the foot pedal 10 lighter and less strenuous, further improving the ease of operation of the equipment.
[0024] The reset assembly includes two secondary slide rods 12 distributed front to back and located on the right side of the slide rod 8. A secondary slider 13 slides up and down on the upper side of the secondary slide rod 12. A secondary pedal 14 is fixed on the lower side of the secondary slider 13. A support frame 15 fixed to the housing 1 is installed between the slide rod 8 and the secondary slide rod 12. Pulleys 16 are rotatably connected to both the upper and lower sides of the support frame 15. A steel rope 17 is connected between the two pulleys 16 for transmission. The slider 9 and the secondary slider 13 are evenly connected by the steel rope 17.
[0025] The combination of pulley 16 and steel rope 17 allows the foot pedal 10 to lift the input end of the long cylinder 11 by simply pressing down on the lower pedal 14. Under atmospheric pressure, the output end of the short cylinder 6 is then reset upwards. This design allows the foot pedal mechanism to be reset by foot control after release, avoiding the need for manual reset by the operator and improving the safety and ease of use of the equipment.
[0026] The fixing assembly includes a right-angled trapezoidal block 18 fixed to the slider 9. The right-angled trapezoidal block 18 is located behind the slider 9 with its inclined surface facing the rear and lower side. A support rod 19 fixed to the housing 1 is installed on the rear side of the right-angled trapezoidal block 18. Two vertically distributed and slidably connected sliding columns 20 are installed on the upper side of the support rod 19. A locking block 21 is fixed on the front side of the sliding column 20. Multiple locking slots 22 that match the right-angled trapezoidal block 18 are evenly opened on the upper side of the locking block 21. A tension spring 23 is connected between the locking block 21 and the support rod 19. A small pedal 24 is hinged to the upper side of the secondary pedal 14. A pull block 29 is fixed to the upper side of the small pedal 24. A conduit 25 is connected to the rear side of the secondary pedal 14 and the rear side of the support rod 19. A pull wire 26 is slidably installed inside the conduit 25. One end of the pull wire 26 is fixedly connected to the pull block 29, and the other end is connected to the locking block 21 for transmission.
[0027] The cooperation of the sliding column 20, the locking block 21, and the tension spring 23 allows the right-angled trapezoidal block 18 and the slot 22 to lock the slider 9 in one direction when the foot pedal 10 moves downward. When the user needs to step on the secondary pedal 14, the operator will step on the small pedal 24. At this time, the pull block 29 can pull the pull cable 26 to pull the locking block 21 to release the right-angled trapezoidal plate. The design of the right-angled trapezoidal block 18, the locking block 21, and the slot 22 allows the slider 9 to be fixed in different positions. This increases the adaptability and flexibility of the equipment, avoids the accidental extension and retraction of the short cylinder 6 caused by the movement of the slider 9, improves the stability of the equipment, and also makes the structure of the fixing component simple and reliable, reducing its maintenance cost.
[0028] A rubber block 27 is installed at the bottom of the output end of the short oil cylinder 6; a light shield 28 is fixed on the upper side of the control panel 3.
[0029] The bottom of the output end of the short hydraulic cylinder 6 is equipped with a rubber block 27, which can effectively protect the output end of the short hydraulic cylinder 6 and increase its friction with the ground, thereby further increasing the stability of the equipment when it is fixed. The sunshade 28 on the upper side of the control panel 3 is used to prevent direct sunlight, so that the staff can more easily observe the equipment test data and further improve the ease of use of the equipment.
