Description

Technical Field

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

[0002] Chinese patent document CN217820516U discloses an auxiliary support frame for measuring insulation resistance meters, belonging to the field of power safety testing technology. This application provides an auxiliary support frame for measuring insulation resistance meters, including an operating panel, and further comprising: a resistance meter body mounted on top of the operating panel; a top cover rotatably connected to the top of the operating panel; a balance adjustment assembly mounted on the bottom of the operating panel for adjusting the operating panel and the resistance meter body to a balanced state; a limiting and fixing assembly mounted on the side wall of the operating panel for limiting and fixing the balance adjustment assembly in a retracted state; and a clamping and fixing assembly mounted on top of the operating 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, and can 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.

[0003] The insulation resistance meter measuring auxiliary support frame in the aforementioned patent document, by placing the insulation resistance meter on a support plate, allows the weight of the meter to act on the support plate. This causes the support plate to press down on a clamping plate via a locking block, thus clamping the insulation resistance meter. A second elastic element is provided at the bottom of the locking block for support. However, during the clamping process, when the insulation resistance meter is relatively light, the locking block cannot generate sufficient downward pressure, resulting in the clamping block failing to secure the meter. Therefore, a resistance testing device for an insulation resistance meter with an adjustable function is proposed. Summary of the Invention

[0004] To address the aforementioned problems, a resistance testing device for an insulation resistance meter with an adjustable function is provided. A worm gear drives a threaded first lead screw to move longitudinally, simultaneously moving a mounting frame. The mounting frame then drives a gear meshing with it via a rack, causing the gear to rotate a bidirectional threaded rod. This rotation of the bidirectional threaded rod causes the clamping plates to move closer or further apart. This solves the problem of easy removal of the resistance meter after testing and resolves the inconvenience of removing the resistance meter after testing.

[0005] To address the problems of existing technologies, the present invention provides a resistance testing device for an insulation resistance meter with an adjustment function, comprising a worktable, a support platform fixed to the upper surface of the worktable, a lifting frame that can move longitudinally inside the support platform, a lifting mechanism on one side of the support platform, a testing device on the top of the lifting mechanism, an adjustment mechanism on one side of the testing device, and a testing head on the adjustment mechanism. A rotatable bidirectional threaded rod is horizontally installed inside the support platform, and a gear is fixed at the center of the bidirectional threaded rod. The lifting frame includes a placement frame installed longitudinally inside the support platform, a rack that can mesh with a gear on the inner side of the placement frame, and a first lead screw fixed longitudinally at the bottom of the placement frame. The support platform is also horizontally installed with a rotatable worm gear. A rotatable worm wheel is provided on the side of the worm gear. The worm wheel is rotatably installed inside the support platform and meshes with the worm gear. A first lead screw is installed at the center of the worm wheel, and the worm wheel and the first lead screw are threaded together. The bidirectional threaded rod is equipped with two sets of clamping plates that can move closer to or further away from each other.

[0006] As a technical solution of the present invention, the adjustment mechanism includes a fixed seat that is horizontally fixed on one side of the detection equipment, two sets of horizontally arranged second lead screws are symmetrically installed inside the fixed seat, and servo motors for driving the second lead screws to rotate are fixed on both sides of the fixed seat. Each of the second lead screws is equipped with a horizontally movable frame. A horizontally movable mounting sleeve is installed at the bottom of one side of the movable frame. A detection head that can be inserted into the ohmmeter socket is horizontally installed on the mounting sleeve.

[0007] As one technical solution of the present invention, a rotatable screw is installed inside the movable frame; The mounting sleeve includes a limiting block mounted on the screw, and the limiting block is threadedly engaged with the screw.

[0008] As one technical solution of the present invention, the detection head includes a mounting post installed inside the mounting sleeve; A tightening sleeve is installed on the outside of one end of the mounting sleeve. The tightening sleeve is tightened and fixed to the end of the mounting sleeve by threads. The tightening sleeve and the mounting sleeve are threaded together.

[0009] As a technical solution of the present invention, an anti-detachment sleeve is installed at one end of the mounting column, and a probe capable of moving along its central axis is installed inside the anti-detachment sleeve. The mounting post contains a return spring for pushing the probe outward.

[0010] As one technical solution of the present invention, an elastic wire is fixed at the other end of the mounting column, and the end of the elastic wire away from the mounting column is electrically connected to the detection equipment.

[0011] As one technical solution of the present invention, the lifting mechanism includes a floating plate disposed on one side of the support platform; A first hydraulic telescopic component for driving the float to move longitudinally is fixed on one side of the support platform, and the output end of the first hydraulic telescopic component is fixedly connected to the float.

[0012] As a technical solution of the present invention, a third slide rail for limiting the position of the floating plate is longitudinally fixed on one side of the support platform. A third groove is longitudinally provided on one side of the float plate, which can slide and cooperate with the third slide rail.

[0013] As one technical solution of the present invention, a sliding seat is installed on the top of the float plate; A fourth hydraulic telescopic component is horizontally fixed to the lower end face of the top of the float plate, and the output end of the fourth hydraulic telescopic component is fixedly connected to the bottom of the slide.

[0014] As a technical solution of the present invention, the upper end surface of the float plate is provided with a fourth sliding groove for limiting the sliding block; A slider that can slide along the fourth groove is fixed to the lower end face of the slide block; A limiting plate is fixed on one side of the slide to prevent the slider from falling off.

[0015] The advantages of this invention compared to the prior art are: 1. This application uses a worm gear to drive a first lead screw, which is threaded with it, to move longitudinally. Simultaneously, the first lead screw moves the placement frame. The placement frame then drives a gear meshing with it via a rack, causing the gear to rotate a double-threaded rod. This rotation of the double-threaded rod causes the clamping plates to move closer or further apart. This solves the problem of easy removal of the resistance meter after testing and resolves the issue of inconvenience in removing the resistance meter after testing.

[0016] 2. This application uses a servo motor to drive the second lead screw to rotate, which in turn causes the moving frame to move along the central axis of the second lead screw. This, in turn, causes the moving frame to move the detection head synchronously via the mounting sleeve. This allows the detection head to be adjusted according to the position of the resistance meter socket.

[0017] 3. This application utilizes a screw to drive a threaded limiting block to slide along the screw, causing the limiting block to drive the mounting sleeve to move horizontally, thereby adjusting the mounting sleeve and allowing the mounting sleeve to drive the detection head to extend horizontally, thus solving the problem of the detection head being unable to extend.

Detailed Implementation

[0030] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0031] See Figures 1-11 As shown, an insulation resistance meter resistance testing device with adjustment function includes a workbench 1, a support platform 2 fixed to the upper surface of the workbench 1, a lifting frame 3 that can move longitudinally inside the support platform 2, a lifting mechanism 5 that is set on one side of the support platform 2, a testing device 6 that is set on the top of the lifting mechanism 5, an adjustment mechanism 7 that is set on one side of the testing device 6, and a testing head 8 that is set on the adjustment mechanism 7. A rotatable bidirectional threaded rod 25 is horizontally installed inside the support platform 2, and a gear 251 is fixed at the center of the bidirectional threaded rod 25. The lifting frame 3 includes a placement frame 31 that is longitudinally installed inside the support platform 2. The inner side of the placement frame 31 is provided with a rack 33 that can mesh with the gear 251. The bottom of the placement frame 31 is longitudinally fixed with a first lead screw 34. Inside the support platform 2, a rotatable worm 24 is horizontally installed. A rotatable worm wheel 23 is provided on the side of the worm 24. The worm wheel 23 is rotatably installed inside the support platform 2 and meshes with the worm 24. A first lead screw 34 is installed at the center of the worm wheel 23 and the worm wheel 23 is threadedly engaged with the first lead screw 34. Two sets of clamping plates 4 are installed on the bidirectional threaded rod 25, which can move closer to or further away from each other.

[0032] When the worm gear 24 is rotated, it drives the worm wheel 23, which meshes with it, to rotate. At this time, the worm wheel 23 drives the first lead screw 34, which is threaded with it, to move longitudinally. Simultaneously, the first lead screw 34 moves the placement frame 31. The placement frame 31 then drives the gear 251, which meshes with it, via the rack 33. This gear 251 then drives the double-threaded rod 25 to rotate. Simultaneously, the rotation of the double-threaded rod 25 causes the clamping plates 4 to move closer or further apart. This solves the problem of easy removal of the resistance meter after testing.

[0033] See Figure 5 , Figure 6 and Figure 7 As shown, the adjustment mechanism 7 includes a fixed base 71 that is horizontally fixed to one side of the detection device 6. Two sets of horizontally arranged second lead screws 711 are symmetrically installed inside the fixed base 71. Servo motors 712 for driving the second lead screws 711 to rotate are fixed on both sides of the fixed base 71. Each of the second lead screws 711 is equipped with a horizontally movable frame 72. A horizontally movable mounting sleeve 73 is installed on the bottom of one side of the movable frame 72. A detection head 8 that can be inserted into the ohmmeter socket is horizontally installed on the mounting sleeve 73.

[0034] The servo motor 712 drives the second lead screw 711 to rotate, which in turn drives the moving frame 72 to move along the central axis of the lead screw 711. This, in turn, causes the moving frame 72 to move the detection head 8 synchronously via the mounting sleeve 73. This allows the detection head 8 to be adjusted according to the position of the resistance meter socket.

[0035] See Figure 5 , Figure 6 and Figure 7 As shown, a rotatable screw 721 is installed inside the movable frame 72; The mounting sleeve 73 includes a limiting block 731 mounted on the screw 721, and the limiting block 731 is threadedly engaged with the screw 721.

[0036] When the screw 721 is rotated, the screw 721 will drive the limiting block 731, which is threadedly engaged with it, to slide along the inside of the screw 721. This causes the limiting block 731 to drive the mounting sleeve 73 to move horizontally, thereby adjusting the mounting sleeve 73. This allows the mounting sleeve 73 to drive the detection head 8 to extend horizontally, solving the problem that the detection head 8 cannot extend.

[0037] See Figure 5 , Figure 6 and Figure 7 As shown, the detection head 8 includes a mounting post 81 installed inside the mounting sleeve 73; A tightening sleeve 732 is installed on the outside of one end of the mounting sleeve 73. The tightening sleeve 732 is tightened and fixed to the end of the mounting sleeve 73 by threads. The tightening sleeve 732 is threadedly engaged with the mounting sleeve 73.

[0038] To ensure the stable installation of the mounting post 81 within the mounting sleeve 73, a tightening sleeve 732 is installed on the outside of one end of the mounting sleeve 73. When the tightening sleeve 732 is rotated, it moves horizontally along the central axis of the mounting sleeve 73, causing it to tighten or release the end of the mounting sleeve 73, thereby clamping or releasing the mounting post 81.

[0039] See Figure 7 As shown, an anti-detachment sleeve 82 is installed at one end of the mounting post 81, and a probe 83 that can move along its central axis is installed inside the anti-detachment sleeve 82. The mounting post 81 has a reset spring 85 installed inside to push the probe 83 outward.

[0040] When probe 83 is inserted into the ohmmeter jack, the reverse force acting on probe 83 compresses the return spring 85, thus preventing damage to probe 83. Simultaneously, the return spring 85 gradually accumulates potential energy. When the compressive force on probe 83 disappears, the accumulated potential energy is released, causing the return spring 85 to push probe 83 back to its initial state.

[0041] See Figure 2 and Figure 3 As shown, an elastic wire 84 is fixed to the other end of the mounting post 81, and the end of the elastic wire 84 away from the mounting post 81 is electrically connected to the detection device 6.

[0042] When probe 83 is inserted into the ohmmeter jack, probe 83 is energized with the ohmmeter. Then, probe 83 is energized with the detection device 6 through mounting post 81 and elastic wire 84, thereby enabling the detection device 6 to detect the voltage of the ohmmeter.

[0043] See Figure 2 , Figure 3 , Figure 8 and Figure 11 As shown, the lifting mechanism 5 includes a floating plate 51 disposed on one side of the support platform 2; A first hydraulic telescopic component 55 for driving the float 51 to move longitudinally is fixed on one side of the support platform 2. The output end of the first hydraulic telescopic component 55 is fixedly connected to the float 51.

[0044] When the output end of the first hydraulic telescopic component 55 retracts, the first hydraulic telescopic component 55 drives the float 51 to move longitudinally through the output end, so that the float 51 drives the detection equipment 6 to adjust its height.

[0045] See Figure 2 , Figure 3 , Figure 8 and Figure 11 As shown, a third slide rail 56 for limiting the position of the float 51 is longitudinally fixed on one side of the support platform 2. A third slide groove 511 is longitudinally provided on one side of the float plate 51, which can slide and cooperate with the third slide rail 56.

[0046] When the float 51 moves longitudinally, it slides along the third slide rail 56 via the third slide groove 511. The third slide groove 511 and the third slide rail 56 cooperate to limit the float 51, effectively preventing the float 51 from shifting during movement. This ensures the stability of the float 51.

[0047] See Figure 3 and Figure 11 As shown, a sliding block 53 is installed on the top of the float 51; A fourth hydraulic telescopic component 57 is horizontally fixed to the lower end face of the top of the float 51, and the output end of the fourth hydraulic telescopic component 57 is fixedly connected to the bottom of the slide block 53.

[0048] When the fourth hydraulic telescopic component 57 is activated, it will drive the slide 53 to move horizontally through the output end, thereby causing the slide 53 to drive the detection device 6 to adjust horizontally.

[0049] See Figure 3 and Figure 11 As shown, the upper end surface of the float 51 is provided with a fourth groove 513 for limiting the sliding block 53. A slider 54, which can slide along the fourth slide groove 513, is fixed to the lower end face of the slide block 53. A limiting plate 52 is fixed on one side of the slide block 53 to prevent the slider 54 from falling off.

[0050] To ensure the stability of the slide block 53, a slider 54 is fixed to the lower end face of the slide block 53. When the slide block 53 moves horizontally, it drives the slider 54 to slide along the fourth slide groove 513. This allows the slider 54 and the fourth slide groove 513 to cooperate in limiting the movement of the slide block 53, effectively preventing it from shifting. Simultaneously, to prevent the slider 54 from falling out of the fourth slide groove 513, a limiting plate 52 is fixed to one side of the slide block 53. This limiting plate 52 then limits the movement of the slider 54, effectively preventing it from falling out of the fourth slide groove 513.

[0051] See Figure 8 , Figure 9 and Figure 10 As shown, the support platform 2 has first sliding grooves 22 longitudinally opened on both sides for limiting the placement rack 31; The two sides of the placement rack 31 are symmetrically fixed with second slide rails 32 that can slide and engage with the first slide groove 22.

[0052] To ensure the stability of the placement rack 31, second slide rails 32 are symmetrically fixed on both sides of the placement rack 31. When the placement rack 31 moves longitudinally, the placement rack 31 will drive the second slide rails 32 to slide along the first slide groove 22, so that the second slide rails 32 and the first slide groove 22 cooperate to limit the placement rack 31, effectively ensuring the stability of the placement rack 31.

[0053] See Figure 8 , Figure 9 and Figure 10 As shown, the first slide rails 21 are horizontally fixed on both sides inside the support platform 2; The clamping plate 4 has symmetrical second sliding grooves 41 on both sides, and the second sliding grooves 41 slide in cooperation with the first slide rail 21.

[0054] To ensure the stability of the clamping plate 4, second sliding grooves 41 are symmetrically opened on both sides of the clamping plate 4. When the clamping plate 4 moves, the clamping plate 4 slides along the first slide rail 21 through the second sliding grooves 41, so that the second sliding grooves 41 cooperate with the first slide rail 21 to limit the clamping plate 4, effectively ensuring the stability of the clamping plate 4.

[0055] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
