Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-5, the present utility model provides a technical solution: a quality detection device for cable insulating material, including a detection device main body 1. There are a positioning box 2 and a movable box 15 that are rotatably and snap-connected on the detection device main body 1. A positioning sleeve 17 and a movable sleeve 7 that are rotatably inserted into each other are respectively provided in the positioning box 2 and the movable box 15. A snap-locating plate 701 is tightly snap-connected in the movable sleeve 7. The lower end of the snap-locating plate 701 is installed with a rotating mechanism 16 through a rotating shaft and a coupling. And the bottom fixed structure of the rotating mechanism 16 is screwed and fixed with the upper movable end of the lifting mechanism 13. This structure enables the lifting mechanism 13 to lift and lower the rotating mechanism 16 under the positioning of the bottom box seat 14. The rotating mechanism 16 drives the movable sleeve 7 to lift and move through the snap-locating plate 701. At the same time, the movable sleeve 7 and the movable box 15 are synchronously lifted and lowered through fixation. And through the rotational drive of the rotating mechanism 16 on the snap-locating plate 701, the movable sleeve 7 and the movable box 15 are synchronously rotated, realizing the movement processing of the clamping mechanism 11 in different detection chambers. Lower partition plates 202 and upper partition plates 1501 corresponding to each other in position are respectively provided in the positioning box 2 and the movable box 15. The lower partition plates 202 and the upper partition plates 1501 are both double-layer plate structures. A seal 1502 is fixedly embedded between the double-layer plate structures of the upper partition plate 1501. And the seal 1502 is in snap-fit with the double-layer plate structure of the lower partition plate 202. When converting the detection chamber, this structure first lifts the movable sleeve 7 and the movable box 15 through the lifting mechanism 13, then rotates the clamping mechanism 11 to the required detection chamber through the rotating mechanism 16, and then makes the upper partition plate 1501 snap into the lower partition plates 202 through the seal 1502, which can realize the sealing treatment of the detection chamber, and plays a role in heat insulation through the double-layer plate structure. And the positioning box 2 and the movable box 15 respectively form a first detection chamber 3, a second detection chamber 4, and a third detection chamber 6 through the lower partition plates 202 and the upper partition plates 1501. A bottom box seat 14 is provided at the bottom of the detection device main body 1. And the bottom box seat 14 is screwed and hermetically fitted with the bottom of the positioning box 2 and the positioning sleeve 17. And a lifting mechanism 13 is screwed and fixed in the middle of the upper end of the bottom box seat 14. A ventilation net plate 5 is snap-connected and installed on the bottom box seat 14. And the ventilation net plate 5 corresponds to the first detection chamber 3, the second detection chamber 4, and the third detection chamber 6 respectively. This structure installs existing heating mechanisms, cooling mechanisms, and humidifying mechanisms in the bottom box seat 14, which can provide different detection environments for the quality detection of cable insulating materials. And by moving the clamping mechanism 11 in different detection chambers, the cable insulating material can quickly reach the detection conditions, so as to perform quality detection processing faster. A clamping mechanism positioning plate 8 is connected to the side of the movable sleeve 7. And fixing members 9 are symmetrically provided below the clamping mechanism positioning plate 8. Driving connecting plates 10 are respectively provided on the opposite sides of the fixing members 9. The positioning box 2, the movable sleeve 7, the movable box 15, and the positioning sleeve 17 are coaxial cylindrical structures.Moreover, through holes corresponding to the positions of the first detection chamber 3, the second detection chamber 4, and the third detection chamber 6 are provided on the outer side of the positioning box 2. A swing door 201 is hinged and fixed at the position of the through hole on the side of the positioning box 2, and the swing door 201 is in sealing cooperation with the positioning box 2. Through holes corresponding to the positions of the first detection chamber 3, the second detection chamber 4, and the third detection chamber 6 are also provided on the side of the movable box 15. In this structure, the movable sleeve 7 and the movable box 15 are fixed by welding, so that the movable sleeve 7 and the movable box 15 can be lifted and rotated synchronously. After the swing door 201 is opened, the clamping mechanism 11 in the detection chamber can be processed, so that the test piece can be fixed and disassembled. Clamping mechanisms 11 corresponding in position are installed at intervals on the opposite sides of the driving connection plate 10. Clamping device telescopic mechanisms 12 are symmetrically connected between the driving connection plate 10 and the fixing member 9. The clamping part of the clamping mechanism 11 is provided with an anti-slip clip 1101, so that the clamping mechanism 11 can rotate through the movable sleeve 7 to switch positions between the first detection chamber 3, the second detection chamber 4, and the third detection chamber 6. The clamping mechanism positioning plate 8 is of a T-shaped structure, and through holes are evenly spaced at both ends of the clamping mechanism positioning plate 8. Movable mounting seats 801 are movably sleeved on both sides of the clamping mechanism positioning plate 8, and the movable mounting seats 801 are fixed by screwing through the through holes on the fixing member 9, and the lower ends of the movable mounting seats 801 are welded to the fixing member 9. In this structure, the movable mounting seats 801 are installed and positioned by the clamping mechanism positioning plate 8, so that the distance between the fixing members 9 can be adjusted, and the fixing members 9 can be fixed at the most suitable positions. The fixing members 9 play a role in installing and positioning the clamping device telescopic mechanisms 12, so that the clamping device telescopic mechanisms 12 can drive and move the driving connection plate 10 under the positioning of the fixing members 9. The clamping mechanism 11 installed through the driving connection plate 10 can clamp the test piece of the cable insulating material through the anti-slip clip 1101. By arranging multiple groups of clamping mechanisms 11, test pieces of different thicknesses can be fixed at the same time, and comparative detection processing can be realized. By stretching the test piece through the clamping device telescopic mechanism 12, the stretchability of the insulating material can be detected. Cooperating with other detection mechanisms, different aspects of detection processing can be carried out. Select a suitable detection mechanism according to the detection requirements and install the detection mechanism at a suitable position on the movable sleeve 7.

[0020] Working principle: When using this quality detection device for insulating materials for cables, first, the bottom box seat 14 enables the first detection chamber 3, the second detection chamber 4, and the third detection chamber 6 to be in high-temperature, low-temperature, and high-humidity environments respectively through the ventilation mesh plate 5. Open the opening and closing door 201 of the detection chamber where the clamping mechanism 11 is located, and sequentially fix the detection pieces of the same size between the clamping mechanisms 11 at the corresponding positions. The anti-slip clamping pieces 1101 play a role in anti-slip clamping. Then close the opening and closing door 201, and transfer the detection piece to the required detection chamber as needed. First, lift the rotating mechanism 16 through the lifting mechanism 13 to make the movable sleeve 7 and the movable box 15 rise, and the seal 1502 is pulled out from the lower partition plate 202. Then, the rotating mechanism 16 drives the movable sleeve 7 to drive the movable box 15 to rotate through the clamping and positioning plate 701. After the adjustment is completed, the lifting mechanism 13 makes the movable sleeve 7 and the movable box 15 descend again, and the seal 1502 is inserted into the lower partition plate 202 to realize the positioning of the upper partition plate 1501 and play a sealing role for this detection chamber. The positioning box 2 and the positioning sleeve 17 are respectively used for the positioning processing of the lifting and rotation of the movable box 15 and the movable sleeve 7. Since the first detection chamber 3, the second detection chamber 4, and the third detection chamber 6 are controlled in environment through the heating mechanism, cooling mechanism, and humidifying mechanism installed in the bottom box seat 14, the detection piece can quickly reach the required detection conditions in the detection chamber. Then, the quality of the detection piece is detected through the detection mechanism. Taking the tensile detection as an example, the clamp telescoping mechanism 12 drives the clamping mechanism 11 to move by driving the connecting plate 10 under the positioning of the fixing member 9, realizing the stretching of the detection piece. The movable mounting seat 801 enables the fixing position of the fixing member 9 on the clamping mechanism positioning plate 8 to be adjustable, making the detection device main body 1 more efficient to use, and thus completing a series of work.
