Description

Technical Field

[0001] This invention belongs to the field of resistance testing technology, and specifically relates to an insulation resistance meter resistance testing device with adjustment function. Background Technology

[0002] Insulation resistance meters are core testing instruments commonly used in power, telecommunications, electromechanical installation and maintenance, and other fields. They are mainly used to check the insulation resistance of electrical equipment, household appliances, or electrical lines to ground and between phases to ensure the normal operation of equipment and lines and prevent safety accidents such as electric shock and equipment damage. During the resistance testing process, the standardization of the testing operation directly determines the accuracy of the test results and the safety of the testing process. The stable fixing of the insulation resistance meter is a crucial prerequisite; incomplete fixing or equipment instability will directly affect the smooth progress of the testing work.

[0003] A search revealed that patent application number CN202221983073.3 discloses an auxiliary support frame for measuring insulation resistance meters. The frame includes an operation panel, and further comprises: a resistance meter body mounted on top of the operation panel; a top cover rotatably connected to the top of the operation panel; a balance adjustment assembly mounted on the bottom of the operation panel for adjusting the operation panel and the resistance meter body to a balanced state; a limiting and fixing assembly mounted on the side wall of the operation panel for limiting and fixing the balance adjustment assembly in its retracted state; and a clamping and fixing assembly mounted on top of the operation panel for quickly clamping and fixing the resistance meter body. This auxiliary support frame for measuring insulation resistance meters can effectively and quickly fix the resistance meter body, improving the stability of the resistance meter body during use. It can also adjust the resistance meter body to a horizontal state, improving the accuracy of the measurement data during use and enhancing the practicality of the device.

[0004] The insulation resistance meter measuring auxiliary support frame in the aforementioned patent document places the insulation resistance meter on a support plate. The weight of the insulation resistance meter acts on the support plate, causing the support plate to press down on the clamping plate via a locking block. A second elastic element is provided at the bottom of the locking block to support it. However, this structure has a problem: when the insulation resistance meter is relatively light, the locking block cannot generate sufficient downward pressure, thus preventing the clamping block from securing the insulation resistance meter.

[0018] The beneficial effects of this invention are: 1) This device, through the coordinated operation of the first threaded rod, the moving block, the buffer, the lower pressure rod, and the side pressure rod, can fix insulation resistance meters of different sizes onto the placement plate. The insulation resistance meter is placed on the placement plate, causing the limiting post on the side pressure rod to engage with the buffer. Rotating the handle drives the first threaded rod to rotate. This rotation causes one end of the side pressure rod to move along the slotted hole on the lower pressure rod, following the fixing post on the moving block. During this movement, the side pressure rod tilts, causing its bottom wall to contact the side wall of the insulation resistance meter placed on the placement plate. Combined with the action of the lower pressure rod, this fixes the insulation resistance meter, ensuring its safety and stability during operation and improving the accuracy of resistance detection.

[0019] 2) With the coordinated operation of the third slider, the first spring, the guide rod, and the buckle, this device can buffer the movement of the moving block and one end of the side pressure rod when the first threaded rod is rotated to fix the insulation resistance meter, preventing the side pressure rod from making direct hard contact with the insulation resistance meter and causing damage to the outer surface of the insulation resistance meter, thus greatly ensuring the safety of the insulation resistance meter.

[0020] 3) The fixed sleeve, guide column, second spring and fixed block of this device can extend the vertical rod, thereby adjusting the distance between the pressure rod and the placement plate. This allows for the placement of insulation resistance meters of different sizes between the pressure rod and the placement plate, ensuring that the device can fix insulation resistance meters of different sizes, greatly improving the flexibility of the device.

[0021] 4) The push-pull rod, sliding rod, connecting rod, and rotating arm of this device form a linkage structure. Under the tension of the third spring, the sliding rod drives the connecting rod to move synchronously. The movement of the connecting rod will drive the positioning rod to move. The movement of the positioning rod will drive one end of the push-pull rod to move. The other end of the push-pull rod will push the rotating arm to rotate around the connection between the rotating arm and the fixed plate. The rotation of the rotating arm can synchronously pull the positioning rod on the other side of the fixed plate to move, so that the positioning rods on both sides always keep moving synchronously towards the center. Under the action of the linkage structure, the positioning rods on both sides will generate a uniform lateral thrust on both sides of the insulation resistance meter, gradually pushing the insulation resistance meter to the center position of the fixed plate and keeping it in a centered state. This effectively avoids problems such as inaccurate probe docking and unstable detection circuit caused by the misalignment of the insulation resistance meter, ensuring that the detection part of the insulation resistance meter can accurately correspond to the detection equipment, thus improving the detection efficiency.

[0022] 5) The cylinder of this device drives the sliding frame and the moving parts to move until the moving parts move to the appropriate position. Then the motor is turned on to drive the first pulley to rotate. Under the action of the first pulley and the second pulley, the normal rotation of the synchronous belt can be ensured. The rotation of the synchronous belt will drive the detection probe on the mounting base to move until the detection probe is inserted into the detection hole on the insulation resistance meter to be tested, thereby realizing the purpose of detecting the resistance of the insulation resistance meter.

[0039] The technical solutions in 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.

[0040] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0041] like Figure 1As shown, an insulation resistance meter resistance testing device with adjustment function includes a workbench 1, a placement rack 3, and a fixing mechanism 4. A fixing seat 2 is provided on one side of the workbench 1, and a lifting component 8 is provided on the fixing seat 2. The lifting component 8 is used to adjust the position of the placement rack 3 to ensure that the insulation resistance meter on the placement rack 3 can easily cooperate with the testing mechanism 7, thereby improving the resistance testing efficiency and quality of the insulation resistance meter by the testing mechanism 7.

[0042] The placement frame 3 is located on top of the lifting component 8. The placement frame 3 is used to support the insulation resistance meter and ensure the safety and stability of the insulation resistance meter during operation.

[0043] The fixing mechanism 4 is installed on the placement frame 3, and the fixing mechanism 4 is used to fix the insulation resistance meter on the placement frame 3.

[0044] The fixing mechanism 4 can fix the insulation resistance meter, ensuring that the insulation resistance meter is always in a stable and safe state during the resistance test, thus ensuring the accuracy of the insulation resistance meter test.

[0045] In this embodiment, as Figure 2 As shown, the placement rack 3 includes a placement plate 301 and a vertical plate 302. The placement plate 301 and the vertical plate 302 are arranged vertically. The placement plate 301 is used to place the insulation resistance meter to ensure that the insulation resistance meter is always in a stable state during the testing process.

[0046] The vertical plate 302 is fixedly installed on the bottom side of the placement plate 301. The vertical rod 402 facilitates the installation of the buffer 4010 and ensures the normal operation of the fixing mechanism 4.

[0047] Both the placement plate 301 and the vertical plate 302 have clearance holes 303. The clearance holes 303 cooperate with the fixing mechanism 4 to ensure that the side pressure rod 408 tilts normally, so that the side pressure rod 408, together with the lower pressure rod 401 and the vertical rod 402, can fix the insulation resistance meter.

[0048] In this embodiment, as Figure 3 As shown, the fixing mechanism 4 includes a pressing rod 401, a buffer 4010, an adjusting member 403, a first threaded rod 405, a moving block 4013, a mounting plate 4015, a mounting block 4016, and a side pressing rod 408. The mounting plate 4015 is fixedly installed on one side of the placement plate 301. The mounting block 4016 is located at the bottom of one end of the mounting plate 4015 and is located at the end away from the placement plate 301. The mounting plate 4015 can expand the placement plate 301 and ensure that insulation resistance meters of different sizes can be placed on the placement plate 301.

[0049] The pressure rods 401 are symmetrically arranged on both sides of the center line of the mounting plate 4015. A vertical rod 402 is provided at one end of the pressure rod 401. Adjusting components 403 are symmetrically arranged on both sides of the mounting block 4016. The vertical rod 402 is slidably mounted on the adjusting component 403. The vertical rod 402, together with the adjusting component 403, can adjust the distance between the pressure rod 401 and the placement plate 301, thereby ensuring that insulation resistance meters of different sizes can be placed on the placement plate 301.

[0050] A first fixing rod 4012 and a second fixing rod 4014 are provided on the pressure rod 401. The first fixing rod 4012 and the second fixing rod 4014 are arranged in parallel. The two ends of the first threaded rod 405 are respectively rotatably installed on the first fixing rod 4012 and the second fixing rod 4014. The arrangement of the first fixing rod 4012 and the second fixing rod 4014 facilitates the installation of the first threaded rod 405 and ensures that the first threaded rod 405 is always in a stable and safe state during operation.

[0051] A handle 4011 is provided at the end of the first threaded rod 405. The handle 4011 makes it easier for the operator to grip and exert force when rotating the first threaded rod 405, which greatly improves the rotation efficiency of the first threaded rod 405.

[0052] To ensure the service life of the handle 4011, a wear-resistant layer can also be applied to the handle 4011.

[0053] The movable block 4013 is threaded onto the first threaded rod 405. A slotted hole 406 is opened on the lower pressure rod 401. Fixed posts 407 are fixedly installed at both ends of the movable block 4013. The fixed posts 407 are slidably disposed in the slotted hole 406. The arrangement of the movable block 4013 and the fixed posts 407 can drive one end of the side pressure rod 408 to move under the action of the first threaded rod 405. At the same time, the arrangement of the fixed posts 407 and the slotted hole 406 can ensure the normal operation of the movable block 4013 and prevent the movable block 4013 from rotating with the first threaded rod 405, thus ensuring the normal operation of the movable block 4013.

[0054] One end of the side pressure rod 408 is rotatably mounted on the fixed column 407. The side pressure rod 408 cooperates with the clearance hole 303. The clearance hole 303 can prevent interference between the placement plate 301 and the vertical plate 302 and the side pressure rod 408 when one end of the side pressure rod 408 moves with the moving block 4013, thus ensuring the normal operation of the side pressure rod 408.

[0055] A limiting post 409 is provided on the other end of the side pressure rod 408, and the buffer 4010 is provided on the vertical plate 302. The limiting post 409 cooperates with the buffer 4010.

[0056] With the coordinated operation of the first threaded rod 405, the moving block 4013, the buffer 4010, the lower pressure rod 401, and the side pressure rod 408, insulation resistance meters of different sizes can be fixed on the placement plate 301. The insulation resistance meter is placed on the placement plate 301, causing the limiting post 409 on the side pressure rod 408 to engage with the buffer 4010. Rotating the handle 4011 drives the first threaded rod 405 to rotate. This rotation causes one end of the side pressure rod 408 to move along the slot 406 on the lower pressure rod 401, following the fixing post 407 on the moving block 4013. During this movement, the side pressure rod 408 tilts, causing its bottom wall to contact the side wall of the insulation resistance meter placed on the placement plate 301. Combined with the action of the lower pressure rod 401, this fixes the insulation resistance meter, ensuring its safety and stability during operation and improving the accuracy of resistance detection.

[0057] In this embodiment, as Figure 5 As shown, the buffer component 4010 includes a third fixing rod 4023, a guide rod 4024, a third slider 4022, a first spring 4025, and a buckle 4026. Two third fixing rods 4023 are arranged parallel to each other, one above the other, and the two third fixing rods 4023 are installed on the vertical plate 302. The arrangement of the third fixing rods 4023 facilitates the installation of the guide rod 4024 and ensures the stability of the guide rod 4024 during operation.

[0058] The guide rods 4024 are symmetrically arranged on both sides of the center line of the third fixed rod 4023, and the two ends of the guide rods 4024 are respectively fixed on the third fixed rods 4023 arranged one above the other. The third slider 4022 is slidably mounted on the guide rods 4024. The guide rods 4024 are used to install the third slider 4022 and can guide the third slider 4022, thus ensuring the normal operation of the third slider 4022.

[0059] The buckle 4026 is fixedly installed on the third slider 4022. The limiting post 409 cooperates with the buckle 4026 to limit the limiting post 409, preventing the limiting post 409 from moving horizontally when one end of the side pressure rod 408 moves, and ensuring that the side pressure rod 408 can tilt normally to limit the side wall of the insulation resistance meter.

[0060] The first spring 4025 is sleeved on the guide rod 4024, and the first spring 4025 is located between the upper third fixing rod 4023 and the third slider 4022. The first spring 4025 is used to provide power for the third slider 4022 to reset, ensuring that the third slider 4022 always has downward stress, and ensuring that the side pressure rod 408 can always contact the side wall of the insulation resistance meter, thereby ensuring the fixing quality and fixing efficiency of the insulation resistance meter.

[0061] With the coordinated operation of the third slider 4022, the first spring 4025, the guide rod 4024, and the buckle 4026, the movement of the first threaded rod 405, which drives the moving block 4013 and one end of the side pressure rod 408, can buffer the insulation resistance meter when it is fixed, preventing the side pressure rod 408 from making direct hard contact with the insulation resistance meter and causing damage to the outer surface of the insulation resistance meter, thus greatly ensuring the safety of the insulation resistance meter.

[0062] In this embodiment, as Figure 4 As shown, the adjusting component 403 includes a fixing sleeve 4017, a guide post 4019, a second spring 4020, and a fixing block 4021. One end of the fixing sleeve 4017 is fixedly installed on the mounting block 4016. The fixing sleeve 4017 is used to limit the left and right swaying of the vertical rod 402, and at the same time, it can provide guidance for the vertical movement of the vertical rod 402.

[0063] A strip-shaped through hole 4018 is opened on one side of the fixed sleeve 4017. Two fixing blocks 4021 are arranged parallel to each other, one above the other. The two fixing blocks 4021 are respectively located at the upper and lower edges of the strip-shaped through hole 4018. The guide post 4019 is fixedly installed on the fixing block 4021. The fixing block 4021 is used to install the guide post 4019 and ensure that the guide post 4019 is stable during operation.

[0064] A guide block 404 is provided on the vertical rod 402. The guide block 404 is slidably mounted on the guide post 4019 through the strip-shaped through hole 4018. The provision of the guide block 404 ensures that the vertical rod 402 can cooperate with the second spring 4020, ensuring that the second spring 4020 can always provide downward stress to the vertical rod 402 and the lower pressure rod 401, thus ensuring the normal operation of the device.

[0065] The second spring 4020 is sleeved on the guide post 4019, and the second spring 4020 is located between the guide block 404 and the upper fixed block 4021. The second spring 4020 can provide the guide block 404 with a downward stress. The guide block 404 with a downward stress will provide the vertical rod 402 with a downward stress. Since the vertical rod 402 is fixedly installed on the lower pressure rod 401, the lower pressure rod 401 also has a downward stress under the action of the vertical rod 402, thereby ensuring that the lower pressure rod 401 is always in close contact with the insulation resistance meter, ensuring the safety of the insulation resistance meter during the testing process.

[0066] The fixed sleeve 4017, guide post 4019, second spring 4020, and fixing block 4021 extend the vertical rod 402, thereby adjusting the distance between the pressure rod 401 and the placement plate 301. This allows insulation resistance meters of different sizes to be placed between the pressure rod 401 and the placement plate 301, ensuring that the device can fix insulation resistance meters of different sizes, greatly improving the flexibility of the device.

[0067] In this embodiment, as Figure 8 As shown, a positioning component 5 is also provided on the top of the pressing rod 401. The positioning component 5 includes a fixed plate 501, a rotating arm 5011, a push-pull rod 5012, a positioning rod 508, a sliding rod 505, a third spring 503, and a connecting rod 507. The fixed plate 501 is fixedly installed on the pressing rod 401. Limiting grooves 5013 are opened on both sides of the center line of the fixed plate 501. The rotating arm 5011 is rotatably installed in the middle of the fixed plate 501 via a shaft. The positioning rod 508 is L-shaped and symmetrically arranged at both ends of the fixed plate 501. The positioning rod 508 cooperates with the limiting groove 5013. The positioning rod 508 is used to push the side wall of the insulation resistance meter so that the insulation resistance meter is always in the middle of the placement plate 301, ensuring the efficiency of the subsequent testing of the insulation resistance meter.

[0068] The two ends of the push-pull rod 5012 are rotatably connected to the end of the rotating arm 5011 and the end of the positioning rod 508, respectively. The push-pull rod 5012 is used to connect the positioning rod 508 and the rotating arm 5011 to ensure that the positioning rod 508 and the rotating arm 5011 can work normally.

[0069] A side plate 5010 is also provided on one side of the fixed plate 501. A first protrusion 504 is provided on the side plate 5010. The side plate 5010 is used to support the first protrusion 504. The side plate 5010 can prevent the first protrusion 504 from interfering with the rotating arm 5011 during operation, thus ensuring the normal operation of the sliding rod 505.

[0070] The connecting rod 507 is fixedly installed on one of the positioning rods 508. A second protrusion 506 is provided on the top of the connecting rod 507. The sliding rod 505 is fixedly installed on the second protrusion 506 and is slidably connected to the first protrusion 504. The arrangement of the first protrusion 504 and the second protrusion 506 facilitates the installation of the sliding rod 505 and ensures the normal operation of the sliding rod 505.

[0071] A plug 502 is provided at the end of the sliding rod 505, and the plug 502 ensures the proper installation of the third spring 503.

[0072] The third spring 503 is sleeved on the sliding rod 505, and the third spring 503 is located between the plug 502 and the first protrusion 504. The third spring 503 is used to provide stress to the sliding rod 505 to ensure that the sliding rod 505 always has stress that moves towards the center of the fixed plate 501.

[0073] The push-pull rod 5012, sliding rod 505, connecting rod 507, and rotating arm 5011 form a linkage structure. Under the tension of the third spring 503, the sliding rod 505 drives the connecting rod 507 to move synchronously. The movement of the connecting rod 507 will drive the positioning rod 508 to move. The movement of the positioning rod 508 will drive one end of the push-pull rod 5012 to move. The other end of the push-pull rod 5012 will push the rotating arm 5011 to rotate around the connection between the rotating arm 5011 and the fixed plate 501. The rotation of the rotating arm 5011 can synchronously pull the fixed plate 501. The positioning rod 508 on the other side moves, so that the two positioning rods 508 always move synchronously towards the center. Under the action of the linkage structure, the two positioning rods 508 will generate a uniform lateral thrust on both sides of the insulation resistance meter, gradually pushing the insulation resistance meter to the center position of the fixed plate 501 and keeping it in a centered state. This effectively avoids problems such as inaccurate docking of the detection probe 7022 and unstable detection circuit caused by the placement of the insulation resistance meter, ensuring that the detection part of the insulation resistance meter can accurately correspond to the detection device 702, and improving the detection efficiency.

[0074] In this embodiment, as Figure 8 , Figure 9 As shown, a limiting block 5014 and a guide plate 509 are also provided on the positioning rod 508. The guide plate 509 is located on the top of the fixed plate 501 and is fixedly connected to the positioning rod 508. The guide plate 509 can prevent the positioning rod 508 from sliding down along the limiting groove 5013, ensuring the stability and safety of the positioning rod 508 during operation.

[0075] The limiting block 5014 is disposed at the bottom of the positioning rod 508, and the limiting block 5014 slides in cooperation with the limiting groove 5013. The setting of the limiting block 5014 can limit the positioning rod 508, prevent the positioning rod 508 from shaking during operation, and ensure the stability and safety of the positioning rod 508 during operation.

[0076] In this embodiment, as Figure 6 , Figure 7 As shown, the lifting component 8 includes a second threaded rod 802, a handle 801, a sliding block 803, a push rod 804, and a bracket 805. A mounting groove 201 is formed in the middle of the fixed base 2. The two ends of the second threaded rod 802 are rotatably mounted on the sidewalls of the mounting groove 201. A rotating shaft 806 is provided at one end of the second threaded rod 802, extending through the sidewall of the mounting groove 201 to the outside of the fixed base 2. The handle 801 is located on the outside of the fixed base 2 and is fixedly mounted on the rotating shaft 806. The threads of the second threaded rod 802 have opposite directions. The sliding blocks 803 are symmetrically arranged at both ends of the centerline of the second threaded rod 802 and are threadedly connected to the second threaded rod 802. The bracket 805 is fixedly mounted on the bottom of the placement plate 301. The two ends of the push rod 804 are rotatably connected to the sliding block 803 and the bracket 805, respectively.

[0077] By rotating the handle 801, the sliding block 803 can be moved inward or outward simultaneously. During the movement of the sliding block 803, one end of the push rod 804 will also move. When one end of the push rod 804 moves outward, it will cause the bracket 805 and the placement plate 301 to move downward. When one end of the push rod 804 moves inward, it will push the bracket 805 and the placement plate 301 to move upward, thus facilitating the testing mechanism 7 to test the insulation resistance meter.

[0078] In this embodiment, as Figure 10 , Figure 11 The diagram also includes a detection mechanism 7 and a support plate 6. The detection mechanism 7 includes a detection device 702, a fixed frame 701, a cylinder 706, a sliding frame 704, and a moving part 707. The support plate 6 is fixedly installed on the workbench 1. Two fixed frames 701 are provided, symmetrically arranged on both sides of the center line of the support plate 6. The detection device 702 is installed on the fixed frame 701. The cylinder 706 is fixedly installed on the fixed frame 701. A first slide rail 705 is provided on the fixed frame 701. A first slider 708 is provided at the bottom of the sliding frame 704. The first slider 708 slides in cooperation with the first slide rail 705. A fourth fixing rod 703 is provided on one side of the sliding frame 704. The piston rod of the cylinder 706 is fixedly connected to the end of the fourth fixing rod 703. The moving part 707 is fixedly installed on the sliding frame 704.

[0079] In this embodiment, as Figure 12 , Figure 13 As shown, the moving component 707 includes a motor frame 709, a motor 7010, a first pulley 7011, a second pulley 7012, a synchronous belt 7018, a connecting block 7013, a sliding plate 7015, a second slide rail 7017, a second slider 7016, a mounting base 7014, a support rod 7019, and a detection probe 7022. The motor frame 709 is fixedly mounted on the top of the sliding frame 704. The motor 7010 is mounted on the motor frame 709. The first pulley 7011 is fixedly mounted on the output shaft of the motor 7010. The second pulley 7012 is rotatably mounted on the sliding frame 704 via a shaft. The second pulley 7012 is connected to the first pulley 7011 via the synchronous belt 7018. The second slide rail 7017 is fixedly mounted on the sliding plate 704. The second slide rail 7017 is located on one side of the motor 7010, and the second slider 7016 is fixedly installed on the bottom of the sliding plate 7015. The second slider 7016 and the second slide rail 7017 are slidably engaged. The sliding plate 7015 is connected to the synchronous belt 7018 through the connecting block 7013. The mounting base 7014 is fixedly installed on the sliding plate 7015. A support rod 7019 is provided on the bottom side of the mounting base 7014. A vertical rod 7020 is provided on the top of the support rod 7019. A protective sleeve 7021 is provided on the vertical rod 7020. The detection probe 7022 is fixedly installed on the mounting base 7014 and is slidably engaged with the protective sleeve 7021. The detection probe 7022 is electrically connected to the detection device 702.

[0080] The working process of testing agency 7 is as follows: When cylinder 706 is activated, the piston rod of cylinder 706 retracts. Since the piston rod of cylinder 706 is fixedly connected to the end of the fourth fixed rod 703 on one side of the sliding frame 704, the extension and retraction of the piston rod will drive the sliding frame 704 to move synchronously. The first slider 708 at the bottom of the sliding frame 704 slides in cooperation with the first slide rail 705 on the fixed frame 701. Under the guidance of the first slide rail 705, the sliding frame 704 moves smoothly along the first slide rail 705, thereby driving the moving part 707 fixedly installed on the sliding frame 704 to move synchronously as a whole until the sliding frame 704 moves to a preset appropriate position, that is, the detection probe 7022 on the moving part 707 is precisely aligned with the detection hole on the insulation resistance meter. At this time, cylinder 706 is closed, and the sliding frame 704 remains fixed in position under the cooperation of the first slider 708 and the first slide rail 705, completing the initial alignment of the detection probe 7022 and the detection hole. After the sliding frame 704 is positioned, the motor 7010 on the moving part 707 is started. The motor 7010 starts working and drives the first pulley 7011 fixedly mounted on its output shaft to rotate synchronously. Since the first pulley 7011 is connected to the second pulley 7012 rotatably mounted on the sliding frame 704 through the synchronous belt 7018, and the synchronous belt 7018 is tensioned, when the first pulley 7011 rotates, it will drive the second pulley 7012 to rotate synchronously through the synchronous belt 7018, thereby ensuring that the synchronous belt 7018 follows the preset trajectory. The synchronous belt 7018 rotates smoothly and at a constant speed, which drives the sliding plate 7015, which is fixedly connected to it through the connecting block 7013, to move synchronously. The second slider 7016 at the bottom of the sliding plate 7015 slides in cooperation with the second slide rail 7017 on the sliding frame 704. Under the guidance of the second slide rail 7017, the sliding plate 7015 moves smoothly along the second slide rail 7017 towards the side closer to the insulation resistance meter, thereby driving the mounting base 7014 and the detection probe 7022, which are fixedly installed on the sliding plate 7015, to move synchronously.

[0081] During the movement of the detection probe 7022, its end slides into the protective sleeve 7021 mounted on the pole 7020. The protective sleeve 7021 guides and protects the detection probe 7022, preventing it from shifting or bending during movement and ensuring that the probe can be accurately aligned with the detection hole of the insulation resistance meter. The motor 7010 continues to operate until the detection probe 7022 is smoothly inserted into the detection hole of the insulation resistance meter and the insertion depth reaches the preset requirement. At this time, the motor 7010 is turned off, and the detection probe 7022 remains inserted and in close contact with the detection hole.

[0082] At this point, the testing agency 7 has completed all preparations, and the testing equipment 702 can perform resistance testing on the insulation resistance meter through the testing probe 7022.

[0083] In this embodiment, as Figure 15As shown, a buffer mechanism 7026 is also provided on the mounting base 7014. The buffer mechanism 7026 includes a sliding sleeve 7030, a fourth spring 7031, a guide rod 7029, a crossbar 7027, a moving plate 7032, a third slide rail 7035, a fourth slider 7033, and a limiting rod 7028. The third slide rail 7035 is fixedly installed on the mounting base 7014, and the fourth slider 7033 is fixedly installed on the bottom of the moving plate 7032. The fourth slider 7033 slides in cooperation with the third slide rail 7035. A vertical plate 7034 is provided on one side of the moving plate 7032, and the detection probe 7022 is installed on the vertical plate 7034. The guide rod 7029 is fixedly installed on the moving plate 7032. On the other side, the sliding sleeve 7030 is slidably mounted on the guide rod 7029. The fourth spring 7031 is sleeved on the guide rod 7029 and is located between the sliding sleeve 7030 and the mounting base 7014. Two crossbars 7027 are provided, and the two crossbars 7027 are symmetrically arranged on both sides of the center line of the guide rod 7029. The crossbars 7027 are fixedly mounted on the mounting base 7014. The limiting rod 7028 is fixedly mounted on the crossbar 7027. There is a gap between the limiting rods 7028 on the two crossbars 7027. The gap between the limiting rods 7028 on the two crossbars 7027 cooperates with the guide rod 7029. The sliding sleeve 7030 cooperates with the limiting rod 7028.

[0084] When the detection probe 7022 is accurately inserted into the detection hole on the insulation resistance meter to be tested, the detection probe 7022 contacts the side wall of the insulation resistance meter. While the motor 7010 is always moving according to the predetermined program, during the process where the detection probe 7022 cannot be inserted, since the detection probe 7022 is fixedly connected to the moving plate 7032, and the moving plate 7032 cannot continue to move forward under the action of the detection probe 7022, the sliding plate 7015 continues to move with the synchronous belt 7018. The limit rod 7028 on the sliding plate 7015 will push the sliding sleeve 7030 to continue to move forward. The sliding sleeve 7030 moves along the guide rod 7029, which will compress the fourth spring 7031, thereby achieving the purpose of buffering the detection probe 7022 and preventing the detection probe 7022 from making hard contact with the insulation resistance meter and causing damage to the detection probe 7022.

[0085] In this embodiment, as Figure 14 As shown, the detection mechanism 7 also includes a correction rod 7025 and a correction plate 7023. The correction plate 7023 is fixedly installed on the side of the sliding frame 704. A correction groove 7024 is opened on the top of the correction plate 7023. The correction rod 7025 is fixedly installed on the sliding plate 7015. The correction rod 7025 cooperates with the correction groove 7024.

[0086] The correction groove 7024 and correction rod 7025 on the correction plate 7023 can correct the sliding plate 7015, prevent the sliding plate 7015 from tilting, which would prevent the detection probe 7022 from being accurately inserted into the detection hole on the insulation resistance meter, thus ensuring the detection efficiency of the insulation resistance meter.

[0087] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the scope defined by the structure of the present invention, they should all fall within the protection scope of the present invention.
