Technical Field

[0001] The utility model relates to a leveling device, in particular to a cement concrete road surface paving and leveling device, belonging to the technical field of road construction devices. Background Art

[0002] During the construction of cement concrete pavement, the surface is relatively rough after the cement is poured, so it needs to be leveled. The cement concrete vibrator can expel the air in the concrete, vibrate and level the concrete cement pavement, and enhance the density of the concrete. During the use of the vibrator, the staff needs to hold the handle to control the movement of the vibrator.

[0003] However, the position of the handle of a traditional vibrating ruler is fixed, so the height cannot be adjusted according to users of different heights, resulting in poor flexibility and comfort in use. Utility Model Content

[0009] Preferably, both ends of the pull plate extend to the outside of the first pull frame, and a T-shaped structure is formed between the pull plate and the sliding rod.

[0010] Preferably, a ruler plate is installed at the bottom end of the vibrating ruler body, and the cross-section of the ruler plate is an L-shaped structure.

[0011] Preferably, the locking structure includes a connecting block and a guide column, two connecting blocks are fixedly connected to the first pull frame, the connecting block is fixedly connected to the guide column, the two guide columns are slidably connected to the same clamping plate, and two clamping slots are provided on the vibrating ruler body, and one end of the clamping plate is engaged with one of the clamping slots.

[0012] Preferably, a second spring is sleeved on the exterior of the guide column, one end of the second spring is fixedly connected to the clamping plate, and the other end of the second spring is fixedly connected to the connecting block.

The first spring contracts, and when one end of the insert block is not engaged with the slot, the second pull frame can be pulled, and the two handles will move with the second pull frame, thereby realizing the adjustment of the handle height. When the handle is adjusted to the appropriate height, one end of the insert block will face the other two slots, and the pull plate can be released at this time. Under the action of the first spring, the plug will move toward the slot and engage with the slot. At this time, the second pull frame cannot slide on the first pull frame, thereby completing the adjustment of the handle height. When people of different heights use it, the height of the handle can be quickly adjusted, thereby effectively improving the flexibility and comfort of use. When it is not needed, the first pull frame can be rotated toward the vibrating ruler body, and then the second pull frame can be pushed into the inside of the first pull frame, thereby realizing the storage of the first pull frame and the second pull frame. After the first pull frame and the second pull frame are stored, the space occupied can be reduced, making it more convenient to transport and store. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] As a technical optimization solution of the utility model, Figure 3 As shown, one end of the first spring 405 abuts against the slide bar 402 , and the other end of the first spring 405 abuts against the first puller 2 , so that the inserting block 403 can always be engaged with the slot 404 under the action of the first spring 405 .

[0025] As a technical optimization solution of the utility model, Figure 2 and Figure 3 As shown, the multiple slots 404 located on the same side of the second pull rack 3 are linearly and equidistantly distributed, and the multiple slots 404 located on both sides of the second pull rack 3 are symmetrically distributed. The cross-section of one end of the sliding rod 402 is a T-shaped structure, and the cross-section of one end of the plug block 403 is a trapezoidal structure, so that it can play a guiding role when the plug block 403 is engaged with the slot 404.

[0026] As a technical optimization solution of the utility model, Figure 1 As shown, both ends of the pulling plate 401 extend to the outside of the first pulling frame 2 , and a T-shaped structure is formed between the pulling plate 401 and the sliding rod 402 , so that the pulling plate 401 can be easily pulled.

[0028] As a technical optimization solution of the utility model, Figure 4 and Figure 5 As shown, the locking structure 5 includes a connecting block 501 and a guide column 502. Two connecting blocks 501 are fixedly connected to the first pulling frame 2, and the guide column 502 is fixedly connected to the connecting block 501. The two guide columns 502 are slidably connected to the same clamping plate 503. Two clamping slots 504 are provided on the vibrating ruler body 1. One end of the clamping plate 503 is engaged with one of the clamping slots 504. A second spring 505 is provided on the outside of the guide column 502. One end of the second spring 505 is fixedly connected to the clamping plate 503, and the other end of the second spring 505 is fixedly connected to the connecting block 501. Therefore, the first pulling frame 2 can be fixed after it is rotated to a certain angle.

[0029] As a technical optimization solution of the utility model, Figure 6 As shown, the cross section of one end of the card plate 503 is T-shaped, and the cross section of the other end of the card plate 503 is trapezoidal, so it can play a guiding role when the card plate 503 is engaged with the card slot 504.

[0030] When the utility model is in use, the staff can hold the handle 6 to control the movement of the vibrating ruler body 1. During the movement of the vibrating ruler body 1, the ruler plate 8 will contact the cement and realize the vibration and leveling of the cement. The comfort of holding can be improved by providing the rubber sleeve 7. When people of different heights operate the vibrating ruler body 1, they can pull the two pulling plates 401 at the same time. The pulling plate 401 drives the sliding rod 402 to move, and the sliding rod 402 drives the two inserting blocks 403 to move away from the slot 404. The first spring 405 contracts. When one end of the inserting block 403 is not engaged with the slot 404, the second pulling frame 3 can be pulled, and the two handles 6 will move with the second pulling frame 3, so as to realize the adjustment of the height of the handle 6. When the handle 6 is adjusted to the appropriate height, one end of the inserting block 403 will face the other two slots 404. At this time, the pulling plate 401 can be released, and under the action of the first spring 405, the inserting block 403 will move toward the slot 404 and engage between the slots 404. At this time, the second pulling frame 3 cannot The first pull frame 2 slides on the first pull frame 2, thereby completing the adjustment of the height of the handle 6. When people of different heights use it, the height of the handle 6 can be quickly adjusted, thereby effectively improving the flexibility and comfort of use. When it is not needed, the card plate 503 can be pulled to shrink the second spring 505. By providing two guide columns 502, the card plate 503 can be guided for movement. When one end of the card plate 503 is not engaged with one of the slots 504, the first pull frame 2 can be rotated, and the card plate 503 will rotate with the first pull frame 2. When one end of the card plate 503 is facing the other slot 504, the two second springs 505 will simultaneously extend to drive the card plate 503 to engage with the other slot 504. At this time, the first pull frame 2 cannot rotate, and then the second pull frame 3 is pushed into the interior of the first pull frame 2, thereby realizing the storage of the first pull frame 2 and the second pull frame 3. After the first pull frame 2 and the second pull frame 3 are stored, the space occupied can be reduced, thereby making it more convenient to transport and store.
