Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4This utility model provides an embodiment: a positioning control device for the compaction barrel of a multifunctional electric compactor, including a base 1; it also includes a card seat 4, a double-ended screw 5, a rubber washer 6, a locking cap 7, and a slot 8. A limit groove 2 is formed in the middle of the upper surface of the base 1, and the compaction barrel body 3 is provided on the upper surface of the limit groove 2. Card seats 4 are provided on both the left and right sides of the outer surface of the compaction barrel body 3. A slot 8 is formed on one side of the card seat 4. Double-ended screws 5 are provided on both the left and right sides of the upper surface of the base 1, and the double-ended screws 5 pass through the slot 8. A rubber washer 6 is provided on the upper part of the outer surface of the double-ended screw 5. The bottom surface of the rubber washer 6 is in contact with the upper surface of the card seat 4. A locking cap is threadedly connected to the outer surface of the double-ended screw 5 above the rubber washer 6. 7. By setting a double-headed screw 5, which is lengthened by one centimeter, after the compaction barrel body 3 is placed inside the limiting groove 2, the two locking seats 4 are respectively fitted onto the outside of the corresponding double-headed screw 5 through the slot 8, thus forming an interlocking state. This prevents the compaction barrel body 3 from rotating during compaction. In addition, by setting a rubber washer 6, the locking cap 7 can be prevented from falling off after multiple vibrations. This improves the safety of the test and the reliability of the data. This solves the problem that the positioning control device of the compaction barrel of the existing multi-functional electric compactor cannot avoid the loosening of the connection point caused by vibration during use, which leads to the phenomenon that the fixing nut is easy to fall off after multiple vibrations, causing the compaction barrel to rotate, resulting in personnel safety and unreliable test data.

[0023] Please see Figures 1-4 In this embodiment, the outer surface of the locking cap 7 is provided with two symmetrical support rods 9. The outer surface of the support rods 9 is provided with anti-slip texture. By providing the support rods 9, a force point is provided for rotating the locking cap 7, which makes it easier for the operator to rotate the locking cap 7. In addition, the anti-slip texture on the surface of the locking cap 7 can increase the friction and prevent slippage. The outer surface of the double-ended screw 5 is provided with an auxiliary nut 10 at the bottom of the card seat 4. The upper surface of the auxiliary nut 10 is in contact with the bottom surface of the card seat 4. By providing the auxiliary nut 10, it can cooperate with the locking cap 7 to improve the fixing effect of the double-ended screw 5. The bottom edge of the inner surface of the limiting groove 2 is provided with a circumferentially distributed positioning groove 11. The compaction barrel body 3 is inserted into the positioning groove 11 through the positioning block. By providing the positioning groove 11, it can cooperate with the positioning block at the bottom of the compaction barrel body 3 to limit the compaction barrel and prevent the compaction barrel body 3 from rotating.

[0024] Please see Figures 1-4In this embodiment, a limiting ring 12 is provided on the upper surface of the base 1 outside the limiting groove 2. Two symmetrical fixing pieces 13 are provided on the side surface of the limiting ring 12. The upper surface of the fixing pieces 13 is provided with screw holes 14. By setting the limiting ring 12, the bottom of the outer surface of the compaction barrel body 3 can be limited. The limiting ring 12 is provided with various different specifications to adapt to different specifications of compaction barrel bodies 3. A fixing seat 15 is installed on the upper surface of the base 1 at the position corresponding to the fixing piece 13. The upper surface of the fixing seat 15 is provided with screw holes 14. A slot 16 is provided, and a fixing piece 13 is adapted to the slot 16. By setting a fixing seat 15 and a slot 16, the fixing piece 13 can be engaged, thereby limiting the position of the limiting ring 12. A washer 17 is provided on the upper surface of the fixing piece 13 corresponding to the position of the screw hole 14. A fixing bolt 18 is provided on the upper surface of the washer 17. The fixing piece 13 is fixed to the fixing seat 15 by the fixing bolt 18. By setting the washer 17 and the fixing bolt 18, the position of the limiting ring 12 can be easily fixed to prevent loosening.

[0025] During operation, the support rod 9 provides a force point for the rotating locking cap 7, making it easy for the operator to rotate the locking cap 7. The anti-slip texture on the surface of the locking cap 7 increases friction and prevents slippage. The auxiliary nut 10 works in conjunction with the locking cap 7 to improve the fixing effect of the double-ended screw 5. The positioning groove 11 works in conjunction with the positioning block at the bottom of the compaction barrel body 3 to limit the compaction barrel and prevent it from rotating. The limiting ring 12 limits the bottom of the outer surface of the compaction barrel body 3. The limiting ring 12 is available in various sizes to fit different sizes of compaction barrel bodies 3. The fixing seat 15 and the slot 16 engage the fixing piece 13 to limit the position of the limiting ring 12. The washer 17 and the fixing bolt 18 secure the position of the limiting ring 12 and prevent it from loosening.

[0026] Through the above steps, by setting the double-headed screw 5 and extending its overall length by one centimeter, after the compaction barrel body 3 is placed inside the limiting groove 2, the two locking seats 4 respectively fit onto the outer side of the corresponding double-headed screw 5 through the slot 8, thus forming an interlocking state. This prevents the compaction barrel body 3 from rotating during compaction. Furthermore, by setting the rubber washer 6, the locking cap 7 can be prevented from falling off after multiple vibrations. This improves the safety of the test and the reliability of the data. This solves the problem that the positioning control device of the compaction barrel of the existing multi-functional electric compactor cannot avoid the loosening of the connection point caused by vibration during use, which leads to the phenomenon that the fixing nut is easy to fall off after multiple vibrations, causing the compaction barrel to rotate, resulting in personnel safety and unreliable test data.
