Description

Technical Field

[0001] This invention relates to the field of electrical variable measurement, specifically to a comprehensive testing device for the performance of electrical equipment. Background Technology

[0002] As a core testing device specifically designed for electrical safety performance testing within the category of electrical instruments and meters, such as power load control systems and power quality monitoring devices, the comprehensive safety testing instrument's core functional system comprehensively covers the measurement and systematic analysis of multiple key electrical variables, including withstand voltage strength testing, insulation resistance performance testing, grounding continuity reliability assessment, accurate leakage current measurement, and power parameter testing. In the field of modern electrical safety testing, the comprehensive safety testing instrument, with its highly integrated testing modules, multi-functional testing capabilities, precise and stable measurement accuracy, and intelligent data analysis functions, has become an indispensable professional testing tool in the factory quality inspection, product type testing, installation and completion acceptance, and daily safety maintenance testing of various electrical equipment. It is widely used in electrical safety quality control in multiple industries such as power, electronics, lighting, home appliances, and electromechanical systems. Especially for electrical products like metal-cased lighting fixtures that pose a direct risk of electric shock during use, industry technical specifications require comprehensive and systematic electrical safety performance testing using a safety compliance testing instrument. These stringent tests scientifically determine whether the product's various electrical safety performance indicators meet standards, ensuring that lighting products maintain a safe, stable, and energy-efficient operating state during subsequent installation and use. This prevents major safety hazards such as electric shock and fire caused by insulation failure, poor grounding, or excessive leakage, thus building a solid technical defense for the electrical safety of end users.

[0003] However, in actual testing operations, when the safety testing instrument performs various electrical variable measurements on lighting products, the operator must manually perform repeated plugging and unplugging operations between the lighting power plug and the tester's output socket. Due to the design of the plug and socket's mating structure and the requirements for contact reliability, there is significant resistance when the plug is inserted into the socket. This requires the operator to continuously grip the plug and apply a stable axial pushing or pulling force during each plugging and unplugging operation to complete the action smoothly. Under the conditions of large-volume, long-term continuous measurement operations, this high-intensity manual operation mode, with operators repeatedly performing forceful gripping and applying force, easily leads to continuous tension and fatigue in the hand muscles. This can cause physiological reactions such as hand soreness, weakness, and fatigue, and over time, may even lead to hand muscle strain and joint discomfort, affecting the occupational health and work comfort of the testing personnel. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a comprehensive testing device for the performance of electrical equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a comprehensive electrical equipment performance testing device, comprising a safety regulation comprehensive tester and a grounding clamp connected to the safety regulation comprehensive tester. A support base is provided below the safety regulation comprehensive tester. A rotating propulsion component is provided at the upper front of the support base. A turntable is connected to the rotating propulsion component. Fixing frames are fixedly installed at the lower front and rear edges of the turntable. Two concave blocks are symmetrically and obliquely fixedly installed at the upper end of the fixing frames. A pressure arm is slidably installed on the side of the fixing frames. Two upper concave blocks are symmetrically and obliquely fixedly installed at the lower end of the pressure arm. A support spring is fixedly installed between the pressure arm and the lower part of the fixing frame. Rollers are installed on the side of the pressure arm. A support frame is fixedly installed at the upper rear of the support base. The safety regulation comprehensive tester is fixed to the upper end of the support frame. A bending pressure frame is provided behind the rollers and fixed to the support frame. A control clamp component for controlling the opening and closing of the grounding clamp is provided at the upper middle of the support base.

[0006] Preferably, the control clamp includes a stand fixedly installed at the upper middle part of the support base, a frame elastically installed at the end of the stand, a control clamping inclined frame fixedly installed at the front end of the frame, a curved frame provided at the front of the stand, the lower end of the curved frame being fixed to the support base, the connecting shaft of the grounding clamp being fixed to the curved frame, and control clamping wheels installed at both pressing ends of the grounding clamp, with the two control clamping wheels respectively abutting against the upper and lower inclined surfaces inside the control clamping inclined frame.

[0007] Preferably, a second rib is fixedly installed at the rear end of the frame, the upright is slidably installed on the outer surface of the second rib, a return spring is fixedly installed between the opposite surfaces of the upright and the frame, the second rib passes through the inside of the return spring, and two positioning seats are symmetrically fixedly installed at the front and rear edges of the upper end of the turntable.

[0008] Preferably, the rotating propulsion component includes a propulsion seat fixedly installed at the upper front of the support base, a propulsion platform slidably installed at the upper end of the horizontal section of the propulsion seat, a propulsion frame fixedly installed at the upper end of the propulsion platform, a shaft seat elastically installed at the front end of the propulsion frame, a drive shaft rotatably installed through the middle of the shaft seat, two fixed frames are arranged rotationally symmetrically about the drive shaft, and the upper end of the drive shaft is fixed to the lower middle of the turntable.

[0009] Preferably, a protruding frame is fixedly installed at the rear end of the shaft seat, a first servo motor is fixedly installed at the end of the protruding frame, the output end of the first servo motor is fixed to the lower end of the drive shaft, and a positioning frame is provided behind the protruding frame, the lower end of the positioning frame is fixed to the support base.

[0010] Preferably, two first-order ribs are symmetrically fixedly installed at the front end of the bearing seat, the push frame is slidably installed on the outer surface of the first-order ribs, and a push spring is fixedly installed between the opposite surfaces of the push frame and the bearing seat, with the first-order ribs passing through the inside of the push spring.

[0011] Preferably, a threaded rod is screwed through the middle of the propulsion platform, and the threaded rod is rotatably connected to the propulsion seat.

[0012] Preferably, a second servo motor is fixedly installed at the rear end of the vertical section of the propulsion seat. The output end of the second servo motor and one end of the threaded rod both extend from the front end of the vertical section of the propulsion seat. The output end of the second servo motor is rotatably engaged with the propulsion seat. A belt is connected between the output end of the second servo motor and one end of the threaded rod via a pulley.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Place the lamp plug into the concave block, then rotate the pusher to move the turntable backward. During this process, the roller will contact the bending frame and roll along the curved section of the bending frame. Under the pressure of the curved section of the bending frame, the pressure arm will move downward, which will in turn move the upper concave block downward to press on the upper part of the plug, thus limiting the plug. At this time, the turntable continues to move backward, and the roller rolls along the lower horizontal surface of the bending frame, keeping the upper concave block pressing on the plug. This keeps the plug in a limited state and moves it backward to insert it into the socket on the safety comprehensive tester. Conversely, rotating the pusher to move the turntable forward will pull the plug out of the socket. The process does not require the measuring personnel to manually insert or remove the plug, effectively reducing hand strain and discomfort.

[0014] 2. Place the lamp holder on the positioning seat of the turntable. At this time, the push platform will drive the push frame to move backward, and the push spring will push the turntable to move backward. During the backward movement, when the lamp holder is located in the clamping end of the grounding clamp, the positioning frame just abuts against the extension frame, keeping the turntable stationary, that is, keeping the lamp holder in the clamping end of the grounding clamp. Then the push frame continues to move backward to push the frame, thereby driving the control clamp inclined frame to move backward, so as to reduce the pushing on the control clamp wheel, so that the clamping end of the grounding clamp can be gathered under its own elastic force to clamp onto the lamp holder. This process does not require manual operation by the measuring personnel, which effectively facilitates the use.

[0015] 3. As a type of electrical instrument and meter for power load control systems, this invention allows for the measurement of electrical variables of lamps placed at the rear of a turntable. Another lamp can be placed at the front of the turntable. After the measurement is completed and the turntable is moved forward and reset, a servo motor will rotate the turntable 180 degrees, swapping the positions of the front and rear lamps. The turntable can then directly move the other lamp backward for measurement. This process can be repeated to save time spent placing lamps, thereby reducing the overall measurement time for the entire batch of lamps, decreasing the idle and continuous operating time of the safety testing instrument, reducing the equipment's own power consumption, and achieving high efficiency and energy saving in measurement operations.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] This invention provides a technical solution: such as Figures 1-8 The diagram shows a comprehensive electrical equipment performance testing device, including a safety comprehensive tester 2 and a grounding clamp 29 connected to the safety comprehensive tester 2. The safety comprehensive tester 2 is a BC96 series. Since using the safety comprehensive tester 2 for electrical variable measurement is existing technology and widely used, its specific structure is not described in detail here. A support base 1 is provided below the safety comprehensive tester 2. A rotating propulsion component is provided at the upper front of the support base 1. A turntable 10 is connected to the rotating propulsion component, and the turntable 10 serves as a load-bearing component. Fixing frames 15 are fixedly installed at the front and rear edges of the lower end of the turntable 10. Two concave blocks 14 are symmetrically and obliquely fixedly installed at the upper end of the fixing frame 15, serving to fix the concave blocks 14. A pressure arm 12 is slidably installed on the side of the fixing frame 15. Two upper concave blocks 13 are symmetrically and obliquely fixedly installed at the lower end of the pressure arm 12. The size of the concave blocks 14 and 13 is adapted to the size of the plug 11 of the lamp 9. This ensures that the concave block 14 and the upper concave block 13 smoothly fit with the plug 11. It also allows the plug 11 to enter the concave block 14 without force. Furthermore, the thickness of the vertical edges of the concave block 14 and the upper concave block 13 should be as thin as possible to ensure that the plug 11 fully engages with the socket 35 on the safety testing instrument 2. The pressure arm 12 serves to fix the upper concave block 13. A fixed connection is installed between the pressure arm 12 and the lower part of the fixing frame 15. A support spring 16 is provided to allow the pressure arm 12 to move upward and reset. A roller 17 is installed on the side of the pressure arm 12. A support frame 3 is fixedly installed at the upper rear of the support base 1. The safety comprehensive tester 2 is fixed at the upper end of the support frame 3. A bending pressure frame 28 is provided behind the roller 17. The cooperation between the bending pressure frame 28 and the roller 17 can control the downward movement of the pressure arm 12. The bending pressure frame 28 is fixed to the support frame 3. A control clamp for controlling the opening and closing of the grounding clamp 29 is provided at the upper middle of the support base 1.

[0020] The clamping device includes a stand 4 fixedly installed at the upper middle part of the support base 1. A frame 32 is elastically installed at the end of the stand 4. A clamping inclined frame 31 is fixedly installed at the front end of the frame 32. The frame 32 serves to connect the clamping inclined frame 31. A bent frame 5 is provided in front of the stand 4. The lower end of the bent frame 5 is fixed to the support base 1. The bent frame 5 serves to bear the load. The connecting shaft of the grounding clamp 29 is fixed to the bent frame 5. Both pressing ends of the grounding clamp 29 are equipped with clamping wheels 30. The two clamping wheels 30 are respectively attached to the upper and lower inclined surfaces inside the clamping inclined frame 31. The clamping inclined frame 31 can push the clamping wheels 30, thereby applying pressure to the pressing end of the grounding clamp 29, so that the clamping end of the grounding clamp 29 can open.

[0021] A second rib 34 is fixedly installed at the rear end of the frame 32. The upright 4 is slidably installed on the outer surface of the second rib 34. The second rib 34 serves to guide the frame 32. A return spring 33 is fixedly installed between the opposing surfaces of the upright 4 and the frame 32. The second rib 34 passes through the inside of the return spring 33. The return spring 33 serves to reset the control clamping frame 31 after it has been moved. Two positioning seats 25 are symmetrically fixedly installed at the front and rear edges of the upper end of the turntable 10. The positioning seats 25 can limit the position of the lamp holder of the lamp 9 so that the grounding clamp 29 can clamp it. The lamp holder of the lamp 9 is placed in the positioning seat 25 on the turntable 10. At this time, the lamp is pushed forward. Platform 36 will drive the pusher frame 18 to move backward, and push the turntable 10 to move backward through the pusher spring 21. During the backward movement, when the lamp holder of the lamp 9 is located in the clamping end of the grounding clamp 29, the positioning frame 6 just abuts against the extension frame 23, keeping the turntable 10 stationary, that is, keeping the lamp holder of the lamp 9 in the clamping end of the grounding clamp 29. Then the pusher frame 18 continues to move backward to push the frame 32, thereby driving the control clamp inclined frame 31 to move backward, so as to reduce the pushing on the control clamp wheel 30, so that the clamping end of the grounding clamp 29 can be gathered under its own elastic force to clamp onto the lamp holder of the lamp 9. The process does not require manual operation by the measuring personnel, which effectively facilitates the use.

[0022] The rotating propulsion component includes a propulsion seat 8 fixedly installed at the upper front of the support base 1. A propulsion platform 36 is slidably installed at the upper horizontal section of the propulsion seat 8, which serves to allow the propulsion platform 36 to slide. A propulsion frame 18 is fixedly installed at the upper end of the propulsion platform 36. A bearing seat 20 is elastically installed at the front end of the propulsion frame 18. A drive shaft 19 is rotatably installed through the middle of the bearing seat 20, which serves to support the drive shaft 19. Two fixed frames 15 are arranged in a rotationally symmetrical manner with the drive shaft 19 as the center, which can ensure that after the drive shaft 19 drives the turntable 10 to rotate 180 degrees, the positions of the two fixed frames 15 can be interchanged. The upper end of the drive shaft 19 is fixed to the lower middle of the turntable 10.

[0023] An extension bracket 23 is fixedly installed at the rear end of the bearing seat 20. A servo motor 24 is fixedly installed at the end of the extension bracket 23. The extension bracket 23 serves to fix the servo motor 24. The output end of the servo motor 24 is fixed to the lower end of the drive shaft 19. The servo motor 24 drives the drive shaft 19 to rotate. A positioning bracket 6 is provided behind the extension bracket 23. The lower end of the positioning bracket 6 is fixed to the support base 1. The positioning bracket 6 serves to position the turntable 10 at the rearward position.

[0024] Two first-order ribs 22 are symmetrically fixedly installed at the front end of the bearing seat 20. The push frame 18 is slidably installed on the outer surface of the first-order ribs 22. The first-order ribs 22 serve to guide the bearing seat 20. A push spring 21 is fixedly installed between the opposing surfaces of the push frame 18 and the bearing seat 20. The first-order ribs 22 pass through the inside of the push spring 21. The push spring 21 serves to push the bearing seat 20 to move.

[0025] A threaded rod 7 is screwed through the middle of the propulsion platform 36. The threaded rod 7 is rotatably connected to the propulsion seat 8, and the threaded rod 7 plays the role of driving the propulsion platform 36 to move.

[0026] A second servo motor 27 is fixedly installed at the rear end of the vertical section of the pusher seat 8. The output end of the second servo motor 27 and one end of the threaded rod 7 both pass through the front end of the vertical section of the pusher seat 8. The second servo motor 27 drives the threaded rod 7 to rotate. The output end of the second servo motor 27 rotates in conjunction with the pusher seat 8. A belt 26 is connected between the output end of the second servo motor 27 and one end of the threaded rod 7 through a pulley. The belt 26 connects the output end of the second servo motor 27 to the threaded rod 7.

[0027] This invention, as a type of electrical instrument for power load control systems, allows for the following measurement: the lamp holder of the metal-cased lamp 9 is placed in the positioning seat 25 on the turntable 10, and the plug 11 of the lamp 9 is placed in the concave block 14. Then, the second servo motor 27 drives the threaded rod 7 to rotate, causing the push platform 36 to move backward, which in turn moves the push frame 18 backward. During this backward movement, the push frame 18, via the push spring 21, pushes the turntable 10 backward. In this process, the roller 17 contacts the bending frame 28 and moves along the bending frame 28... The curved section of the bending frame 28 rolls, causing the pressure arm 12 to move downward under the pressure of the curved section of the bending frame 28. This, in turn, causes the upper concave block 13 to move downward and press against the upper part of the plug 11, thus limiting the plug 11. At this time, the turntable 10 continues to move backward, while the roller 17 rolls along the lower horizontal plane of the bending frame 28, keeping the upper concave block 13 pressed against the plug 11. This keeps the plug 11 in a limited state as it moves backward and inserts into the socket 35 on the safety comprehensive tester 2. After insertion, the lamp holder of the lamp 9 is exactly located within the clamping end of the grounding clamp 29. When the positioning frame 6 abuts against the extension frame 23, the turntable 10 remains stationary, ensuring that the lamp holder of the lamp 9 is positioned within the clamping end of the grounding clamp 29. Then, the pusher frame 18 continues to move backward, pushing the frame 32 and causing the control clamp inclined frame 31 to move backward, reducing the pushing force on the control clamp wheel 30. This allows the clamping end of the grounding clamp 29 to close under its own elasticity, clamping it onto the lamp holder of the lamp 9. The electrical variables of the lamp 9 can then be measured using the safety comprehensive tester 2. During the measurement process, another... A lamp 9 is placed at the front of the turntable 10. After the measurement is completed and the turntable 10 moves forward and resets, the first servo motor 24 will drive the turntable 10 to rotate 180 degrees, so that the front and rear lamps 9 are interchanged. Then the turntable 10 can directly drive another lamp 9 to move backward for measurement. This process is repeated to save the time spent placing the lamp 9, thereby reducing the overall measurement time of the entire batch of lamps 9, reducing the no-load and continuous operation time of the safety comprehensive tester 2, reducing the power consumption of the equipment itself, and achieving high efficiency and energy saving in measurement operations.
