Description

Technical Field

[0001] The utility model relates to the technical field of concrete surface treatment equipment, in particular to a concrete surface vibration leveler. Background Art

[0002] Concrete is often needed in the construction industry. Currently, most concrete laying is done manually. In order to ensure the flatness and density of the concrete surface, a concrete surface vibrator is used. The existing concrete surface vibrator is generally composed of a vibration motor and a vibration base. During operation, the vibration motor drives the vibration base to vibrate and transfers the vibration energy to the concrete, thereby achieving the purpose of making the concrete dense. The vibration base is in contact with the concrete surface, and its lower surface will wear during use. The vibration motor and the vibration base are generally connected by bolts, which has a simple structure. However, the concrete can easily contaminate the bolts during use, which will cause the vibration base to be difficult to disassemble and replace, affecting the convenience of use.

Rectangular holes 17 are provided at the four corners of the lower surface of the vibration seat 1, and a card seat 4 is provided at the four corners of the upper surface of the bottom plate 3. The card seat 4 is an inverted L-shaped card seat. The card seat 4 is movably connected to the vertically corresponding rectangular hole 17. The internal height is equal to the thickness of the vibration seat 1 plate, and there is no gap between the upper and lower parts. The bottom plate 3 drives the card seat 4 to move forward synchronously, and then the card seat 4 will align with the rectangular hole 17 The bottom plate 3 is moved forward by the rotation of the rotating shaft 5, and the upper end of the rotating shaft 5 is provided with a handle 10, and the rotating shaft 5 is rotated counterclockwise by the handle 10. There is a positioning seat 8, the rotating shaft 5 is located inside the positioning seat 8, and two positioning grooves 16 are provided on the outer arc surface of the rotating shaft 5. A spring piece 9 is provided at the mounting hole on the upper end of the outer arc surface of the positioning seat 8. The two positioning grooves 16 are both arranged in conjunction with the spring piece 9. The rotating shaft 5 drives the positioning groove 16 to gradually separate from the spring piece 9. The wall of the positioning groove 16 will drive the spring piece 9 to undergo elastic deformation. The spring piece 9 positions the rotating shaft 5 through the positioning groove 16. A protective cover 11 is provided on the upper end of the outer arc surface of the rotating shaft 5. The spring piece 9 is located inside the protective cover 11. The protective cover 11 provides protection for the spring piece 9 to prevent concrete from contaminating the spring piece 9.

The inside of the circular hole A spring 13 is installed at the upper end, and the spring 13 is located above the circular shaft 6. The circular shaft 6 can be retracted to prevent the circular shaft 6 from being bent during the disassembly process of the base plate 3.
