Description

Technical Field

[0001] The present invention relates to the technical field of high-voltage cables, and particularly relates to a universal fixing clip for cable testing. Background Art

[0002] A test stand for supporting cables is an auxiliary device for power cable testing, mainly used to support, fix and position cables during the cable testing process to ensure the smooth progress of the test and the accuracy of the test results. The design inspiration of the umbrella-type cable test stand comes from the umbrella-shaped structure in nature, aiming to provide more stable supporting force and more flexible adaptability.

[0003] However, in the prior art, the terrain and space conditions of different cable test sites are diverse. A single fixed test stand is difficult to adapt to complex terrains such as mountains and slopes, as well as indoor sites with relatively low or high ceiling heights. In these cases, the test stand cannot provide a suitable support height for the cable, resulting in the inability to conduct the test normally. Moreover, in some projects that require frequent movement of the test site or different types of cable tests, the bulky and non-retractable test stand will become a great obstacle. It is necessary to equip each test site with a dedicated test stand, which increases the equipment cost and management difficulty, and also reduces the flexibility and efficiency of project implementation. Summary of the Invention

[0004] The purpose of the present invention is to solve the disadvantages existing in the prior art, and provide a universal fixing clip for cable testing. In this way, whether it is a flat ground, a slope or an irregular ground, stable support can be achieved by adjusting the angle and length of the legs, avoiding the restriction of test development due to ground conditions, and it can be quickly folded and unfolded, greatly reducing the volume of the test stand in the non-use state, facilitating transportation and storage. In this way, the cable can maintain a specific shape and orientation, preventing it from bending, twisting or deforming too much due to factors such as its own gravity and external force pulling during the test, and ensuring that the cable is in an ideal state that meets the test requirements.

[0005] To achieve the above purpose, a universal fixing clip for cable testing is provided, including a sleeve. A plurality of limiting holes are provided inside the sleeve. A first rotating shaft is threadedly connected inside the sleeve. One end of the first rotating shaft is rotatably fixedly connected to a first fixing block. Two nuts are threadedly connected to both sides of the first fixing block. A turntable is fixedly connected to the outside of the first fixing block. The other end of the first rotating shaft is fixedly connected to a second fixing block. A sliding rod is slidably connected inside the sleeve.

[0006] Moreover, two first support columns are fixedly connected to the outside of the sleeve. A first clamping block is slidably connected inside the first support column.

[0007] Moreover, one end of the first support column is rotatably connected to a connecting rod, one end of the connecting rod is fixedly connected to a second support column, and one end of the second support column is fixedly connected to a first support block.

[0008] Moreover, the bottom of the sleeve is fixedly connected to a chassis, and a rotating column is rotatably connected to the outside of the sliding rod.

[0009] Moreover, a plurality of second support blocks are fixedly connected to the outside of the rotating column, and a second rotating shaft is rotatably connected to the inside of the second support block.

[0010] Moreover, one end of the second support block is fixedly connected to a placement plate, and a plurality of card slots are formed in the inside of the placement plate.

[0011] Moreover, a plurality of third rotating shafts are rotatably connected to the outside of the placement plate, and a ferrule is fixedly connected to the outside of the third rotating shaft.

[0012] Moreover, one end of the ferrule is fixedly connected to a second clamping block, and the outside of the ferrule is detachably connected to the card slot.

[0013] Beneficial effects:

[0014] 1. Place the sleeve at the designated position. At the same time, press the first clamping block so that the connecting rod at one end of the first support column rotates in the groove provided inside the first support column, thereby unfolding the second support column, and inserting the first support block at one end of the second support column into the ground to achieve a fixing effect. Then, rotate the nut to remove the first fixing block together with the turntable, and rotate the first rotating shaft to pull it out of the limit hole. Adjust the height of the sliding rod according to the needs of the operator. After adjustment, install the nut on the first fixing block and the rotating shaft again. In this way, whether it is a flat ground, a slope, or an irregular ground, the stable support can be achieved by adjusting the angle and length of the legs, avoiding the limitation of the test due to ground conditions, and it can be quickly folded and unfolded, greatly reducing the volume of the test stand in the non-use state, which is convenient for transportation and storage.

[0015] 2. Rotate the second rotating shaft to unfold the second support block so that the placement plate at one end of the second support block is in a horizontal position. After adjustment, install the cable on the placement plate, and rotate the ferrule through the third rotating shaft so that the second clamping block at one end of the ferrule aligns with the card slot to fix the cable. There is a rotating column at the bottom of the placement plate, and the angle of the placement plate can be freely adjusted according to the direction of the cable required by the operator. In this way, the cable can maintain a specific shape and orientation, preventing it from bending, twisting, or deforming too much due to its own gravity, external force pulling, etc. during the test, ensuring that the cable is in an ideal state that meets the test requirements.

[0025] Refer to Figures 1-4, in an embodiment of the present invention, a universal fixing clip for cable testing includes a sleeve 1. A plurality of limiting holes 2 are provided inside the sleeve 1, which can effectively limit the movement range of parts and prevent them from exceeding the predetermined position. A first rotating shaft 7 is threadedly connected inside the sleeve 1. It is an important component for connecting and driving rotating parts, capable of transmitting power and torque, while supporting and positioning related parts. One end of the first rotating shaft 7 is rotatably and fixedly connected to a first fixing block 12. Two nuts 13 are threadedly connected to both sides of the first fixing block 12.

[0026] Specifically: Place the sleeve 1 at the designated position. At the same time, press the first clamping block 8 so that the connecting rod 9 at one end of the first support column 4 rotates in the groove provided inside the first support column 4, thereby unfolding the second support column 10 and inserting the first support block 11 at one end of the second support column 10 into the ground to achieve the fixing effect. Then, rotate the nut 13 to remove the first fixing block 12 together with the turntable 14, and rotate the first rotating shaft 7 to pull it out from the limiting hole 2, and adjust the height of the sliding rod 5 according to the needs of the operator.

[0027] Two first support columns 4 are fixedly connected to the outside of the sleeve 1. A first clamping block 8 is slidably connected inside the first support column 4, which is used to connect and fix mechanical parts to ensure the stability and integrity of the structure.

[0028] One end of the first support column 4 is rotatably connected to a connecting rod 9. One end of the connecting rod 9 is fixedly connected to a second support column 10. One end of the second support column 10 is fixedly connected to a first support block 11.

[0033] A plurality of third rotating shafts 20 are rotatably connected to the outside of the placement plate 18, and a ferrule 21 is fixedly connected to the outside of the third rotating shaft 20.

[0034] One end of the ferrule 21 is fixedly connected with a second clamping block 22, and the outside of the ferrule 21 is detachably connected with the clamping groove 19.

[0035] Specifically: After adjustment, the cable is installed on the placement plate 18, and the ferrule 21 is rotated through the third rotating shaft 20, so that the second clamping block 22 at one end of the ferrule 21 is aligned with the clamping groove 19 to fix the cable. There is a rotating column 6 at the bottom of the placement plate 18, and the angle of the placement plate 18 can be freely adjusted according to the direction of the cable required by the operator.

[0036] Working principle: Place the sleeve 1 at the designated position, and at the same time press the first clamping block 8 so that the connecting rod 9 at one end of the first support column 4 rotates in the groove provided inside the first support column 4, thereby unfolding the second support column 10, and inserting the first support block 11 at one end of the second support column 10 into the ground to achieve a fixing effect. Then rotate the nut 13 to remove the first fixing block 12 and the turntable 14, and rotate the first rotating shaft 7 to pull it out of the limit hole 2. Adjust the height of the sliding rod 5 according to the needs of the operator. After adjustment, install the nut 13 on the first fixing block 12 and the first rotating shaft 7. In this way, whether it is a flat ground, a slope or an irregular ground, the stable support can be achieved by adjusting the angle and length of the legs, avoiding the limitation of the test due to the ground conditions, and it can be quickly folded and unfolded, greatly reducing the volume of the test stand in the non-use state. Rotate the second rotating shaft 17 to unfold the second support block 16 so that the placement plate 18 at one end of the second support block 16 is in a horizontal position. After adjustment, install the cable on the placement plate 18, and rotate the ferrule 21 through the third rotating shaft 20 so that the second clamping block 22 at one end of the ferrule 21 is aligned with the clamping groove 19 to fix the cable. There is a rotating column 6 at the bottom of the placement plate 18, and the angle of the placement plate 18 can be freely adjusted according to the direction of the cable required by the operator. In this way, the cable can maintain a specific shape and orientation, preventing it from bending, twisting or deforming too much due to its own gravity, external pulling and other factors during the test.
