[0035] This invention provides a portable cable insulation testing device through improvements. The technical solution of this invention is as follows:
[0036] Example 1:
[0037] like Figure 1 - Figure 10 As shown, the technical solution of the present invention is: a portable cable insulation testing device, including a storage box 1, wherein the inner wall of the storage box 1 is symmetrically provided with an inner slide rail 7 about its transverse center line, and a testing mechanism 6 is slidably connected in the inner slide rail 7.
[0038] The detection mechanism 6 includes a vertical frame 601, a horizontal plate frame 604 on one side of the vertical frame 601, and T-shaped slide members 602 on both sides of the horizontal plate frame 604. The T-shaped slide members 602 are slidably connected to the inner slide rail 7. A side hole 6011 is provided on one side of the vertical frame 601 about its center line, and a vertical hole 607 is provided on the upper surface of the horizontal plate frame 604. The side hole 6011 and the vertical hole 607... Simultaneously, a U-shaped tie rod 605 is slidably connected internally. An L-shaped connecting rod 6021 is provided on one side of the U-shaped tie rod 605, and a connecting rod frame 6019 is vertically connected to the L-shaped connecting rod 6021. A lower detection ring 6012 is provided on the upper surface of the U-shaped tie rod 605 in the horizontal direction. A guide hole 6022 is opened on the upper surface of the vertical frame 601, and the inner cavity of the guide hole 6022 is slidably connected to the lower detection ring 6012. A U-shaped frame 6023 is provided on one side of the vertical frame 601 above the side hole 6011, and an upper detection ring 6013 is provided on one side of the U-shaped frame 6023, with the upper detection ring 6013 corresponding to the lower detection ring 6012. A detector 609 is installed on one side of the vertical bracket 601 away from the side hole 6011, and a second wire 6018 is connected to one side of the detector 609. One end of the second wire 6018 is connected to the lower detection ring 6012. A first wire 608 is connected to the upper end of the detector 609, and one end of the first wire 608 is connected to the upper detection ring 6013. This structure allows the lower detection ring 6012 to move downwards as the U-shaped pull bracket 605 is pulled when the cable 6010 needs to be tested. Simultaneously, the side of the U-shaped pull bracket 605 can simultaneously move the L-shaped connecting rod 6021. The L-shaped connecting rod 6021 then drives the connecting rod frame 6019, allowing the L-shaped connecting rod 6021 to pull the outer fastener 6014 through the bearing 6020. The outer fastener 6014 then separates from the lower fastener frame 6017, and the lower detection ring 6012 moves downwards simultaneously, facilitating the fitting of the cable 6010. Next, the handle 606 is pushed upwards, allowing the slot 6016 at the end of the outer fastener 6014 to easily engage with the plug 6015 on the lower fastener frame 6017. Thus, the outer fastener 6014 and the lower fastener frame 6017 can easily wrap the cable 6010. The outer fastener 6014 and the lower fastener frame 6017 also provide auxiliary fixation for the upper detection ring 6013 and the lower detection ring 6012 to perform stable detection of the cable 6010.
[0039] Furthermore, each end of the connecting rod 6019 is hinged to a bearing 6020, and each of the two bearings 6020 is connected to an outer fastener 6014. One end of each of the two outer fasteners 6014 is hinged to a lower fastener 6017, and an insert 6015 is provided on the outer wall of one end of each of the two lower fasteners 6017. This structure allows the handle 606 to move the U-shaped pull bracket 605, and then the U-shaped pull bracket 605... The lower detection ring 6012 can be driven, and the U-shaped pull bracket 605 can drive the L-shaped connecting rod 6021 to move. Then, the L-shaped connecting rod 6021 can drive the outer fastener 6014 through the connecting rod frame 6019. In this way, the lower fastener frame 6017 can fasten with the outer fastener 6014. Then, when it is necessary to perform insulation damage testing on the cable 6010, the lower detection ring 6012 and the connecting rod frame 6019 are driven synchronously. In this way, the connecting rod frame 6019 can pull the outer fastener 6014, so that the outer fastener 6014 and the lower detection ring 6012 can conveniently perform fitting testing on the cable 6010.
[0040] Furthermore, an insert 6015 is provided on the outer wall of one end of the outer fastener 6014, and the insert 6015 engages with the slot 6016. This structure allows the cable 6010 to be stably connected to the outer fastener 6014 and the lower fastener 6017 when it is necessary to test the cable 6010. Then, when the upper detection ring 6013 and the lower detection ring 6012 test the cable 6010, the outer fastener 6014 and the lower fastener 6017 can be used to fix the cable 6010, thus enabling the upper detection ring 6013 and the lower detection ring 6012 to stably test the cable 6010.
[0041] Furthermore, both ends of the U-shaped bracket 605 are connected to handles 606. The handles 606 can conveniently drive the lower detection ring 6012 and the connecting rod 6019 synchronously. During the driving process, the connecting rod 6019 can control the opening and closing of the outer fastener 6014 and the lower fastener 6017. At the same time, the lower detection ring 6012 can conveniently detect the cable 6010 during its up and down movement.
[0042] Furthermore, a first grip groove 603 is provided on the upper surface of the horizontal plate frame 604 away from the vertical hole 607. This structure allows the testing personnel to hold the device with both hands at the first grip groove 603 and the handle 606 when the testing device needs to be used to test the cable 6010. This allows the personnel to stably test the cable 6010 using the testing device.
[0043] Furthermore, the storage box 1 is provided with limiting kits 4 on both sides, and the limiting kits 4 are U-shaped. The upper end of the storage box 1 is fastened with a cover 3. The lower surface of the cover 3 has symmetrical protruding clips 5 about its transverse center line, and the two protruding clips 5 are engaged with the inner cavities of the two limiting kits 4. The upper end of the cover 3 is provided with a pull buckle 2. Through the above structure, when it is necessary to slide the T-shaped slides 602 on both sides of the detection mechanism 6 into the inner slide rails 7 in the inner cavity of the storage box 1, the protruding clips 5 on both sides of the cover 3 are engaged with the limiting kits 4 on both sides of the storage box 1. In this way, the cable insulation detection device can be conveniently carried through the storage box 1.
[0044] Furthermore, two lower fasteners 6017 and two outer fasteners 6014 are provided, and the lower fasteners 6017 and the outer fasteners 6014 form a ring structure. The cable 6010 is fitted inside the inner cavity of the ring structure. With the above structure, when the cable 6010 is tested by the lower detection ring 6012 and the upper detection ring 6013, the outer fasteners 6014 and the lower fasteners 6017 can clamp and fix the two sides of the upper detection ring 6013 and the lower detection ring 6012. In this way, the two outer fasteners 6014 and the lower fasteners 6017 can easily assist in fixing the cable 6010.
[0045] Example 2:
[0046] like Figure 11 - Figure 12 As shown, a lower limit mechanism 9 is provided on one side of the lower buckle frame 6017. The lower limit mechanism 9 includes a base 901, which is connected to the side wall of the lower buckle frame 6017. The base 901 is connected to a rotating bracket 902 via a rotating shaft. A buckle block 903 is provided on the upper surface of the rotating bracket 902, and lower rollers 904 are connected to both sides of the end of the rotating bracket 902 via rotating shafts. The lower buckle frame 6017 The inner surface of the device has a slot 10, which engages with the buckle block 903. The outer fastener 6014 has a threaded groove on one side, which is threadedly connected to the threaded post 802. With the above structure, when the cable 6010 is being tested, the threaded post 802 at one end of the upper limit mechanism 8 is connected to the threaded hole on one side of the outer fastener 6014. Then, the rotating bracket 902 is rotated, and the rotating bracket 902 can rotate on the base 901 via the rotating shaft. After rotation, the lower roller 904 and the upper roller 801 can easily guide the cable 6010 in orientation. Thus, the testing device can perform testing more smoothly with the assistance of the lower roller 904 and the upper roller 801.
[0047] Working principle: When the detection mechanism 6 needs to be removed from the storage box 1, pull the protruding clips 5 on both sides of the cover 3 out of the inner cavity of the limiting kit 4, and then slide the detection mechanism 6 out of the inner slide rail 7 through the T-shaped sliders 602 on both sides. In this way, the detection mechanism 6 can be easily removed from the storage box 1. Then, grasp the handle 606 with one hand and the first grip groove 603 with the other hand, and then pull down the handle 606. The handle 606 can drive the U-shaped pull bracket 605 to move down. Then, as the U-shaped pull bracket 605 moves down, it can move the lower detection ring 6012 down. At the same time, the side of the U-shaped pull bracket 605 can simultaneously drive the L-shaped connecting rod 6021. Then, the L-shaped connecting rod 6021 drives the connecting rod frame 6019. In this way, the L-shaped connecting rod 6021... The outer fastener 6014 can be pulled by the bearing 6020, allowing it to separate from the lower fastener frame 6017. Simultaneously, the lower detection ring 6012 moves downward, facilitating the fitting of the cable 6010. Then, by pushing the handle 606 upward, the slot 6016 at the end of the outer fastener 6014 can easily engage with the plug 6015 on the lower fastener frame 6017. The outer fastener 6014 and lower fastener frame 6017 effectively wrap the cable 6010. Furthermore, the outer fastener 6014 and lower fastener frame 6017 provide auxiliary fixation for the upper detection ring 6013 and lower detection ring 6012 during cable 6010 testing, ensuring stable testing. This prevents instability caused by wind speed during cable 6010 inspection. This is the working principle of this portable cable insulation testing device.
