[0029] like Figure 1 As shown, the road paving and leveling bracket 1 includes a base 11, a support rod 12, a limit sleeve 13, a locking assembly 14 and a support assembly 15. The base 11 is used to be erected on a construction site. The support rod 12 is erected on the base 11 in a vertical direction. The limit sleeve 13 is sleeved on the support rod 12 and is used to rise and fall and slide along the support rod 12, so as to adjust the installation height of the limit sleeve 13. The locking assembly 14 and the support assembly 15 are respectively arranged on the limit sleeve 13.

[0030] Furthermore, the locking assembly 14 is used to lock and fix the limiting sleeve 13 relative to the support rod 12, and then the limiting sleeve 13 can be locked and fixed after the installation height adjustment of the limiting sleeve 13 is completed to prevent the limiting sleeve 13 from loosening. The supporting assembly 15 includes a supporting ring 151 arranged around the limiting sleeve 13 and a connecting rod 152 arranged between the supporting ring 151 and the limiting sleeve 13. The connecting rod 152 connects the supporting ring 151 and the limiting sleeve 13 into a whole, so as to form a disc-shaped supporting structure on the outer periphery of the limiting sleeve 13. The supporting ring 151 is used to support the leveling member 2.

[0031] Please combine Figure 2 In the road paving leveling bracket 1, the support assembly 15 is combined on the outer periphery of the limiting sleeve 13 through the support ring 151 and the connecting rod 152 to form a disc-shaped support structure, which can support the leveling member 2 in any direction, has strong applicability, and does not require precise adjustment of the support angle during use.

[0032] like Figure 1As shown, preferably, there are multiple connecting rods 152, and the multiple connecting rods 152 are equidistantly arranged along the circumference of the support ring 151, so that the support ring 151 and the limit sleeve 13 are connected into a whole through the multiple connecting rods 152, thereby strengthening the support of the support ring 151 and improving stability, and the connecting rods 152 can also assist in supporting the leveling member 2.

[0033] Please combine Figure 3 The limiting sleeve 13 is provided with a threaded hole (not numbered, the same below) along the direction toward the support rod 12, and the locking assembly 14 includes a screw rod 141 and a driving handle 142. The screw rod 141 is penetrated into the threaded hole and is threadedly connected with the threaded hole. The driving handle 142 is arranged on one end of the screw rod 141 away from the support rod 12. The driving handle 142 is used to drive the screw rod 141 to rotate, thereby driving the screw rod 141 to move in the direction toward the support rod 12 and press against the support rod 12 through the threaded matching structure, or driving the screw rod 141 to move in the direction away from the support rod 12 and disengage from the support rod 12, thereby realizing the locking, fixing or unlocking action of the limiting sleeve 13 relative to the support rod 12.

[0035] Preferably, the driving handle 142 is configured as a long strip structure, and the surface of the driving handle 142 is provided with a first elevation scale line 1421 along its length direction. The first elevation scale line 1421 can assist in positioning the height of the driving handle 142, thereby positioning the height of the limit sleeve 13, and then positioning the support height of the support assembly 15, so as to facilitate and quickly adjust the leveling height of the leveling member 2.

[0036] Preferably, the driving handle 142 is provided with an axial hole, and the screw rod 141 includes a transmission shaft passing through the axial hole, and the axial hole includes a first axial hole 1422, a second axial hole 1423 and a third axial hole 1424 which are arranged in a direction away from the support rod 12 and whose diameters decrease successively, and a driving tooth is arranged circumferentially on the inner wall of the second axial hole 1423, and the transmission shaft includes a first transmission shaft 1411 and a second transmission shaft 1412 which are arranged in a direction away from the support rod 12, and a transmission tooth matched with the driving tooth is arranged circumferentially on the outer wall of the first transmission shaft 1411, and the second transmission shaft 1412 is matched with the third axial hole 1424 and can be slidably passed through the third axial hole 1424, and the driving handle 142 is used to move along the axial direction of the second transmission shaft 1412 and to engage or disengage the driving tooth relative to the transmission tooth.

[0037] Specifically, the lateral movement direction of the driving handle 142 is limited by the limiting cooperation between the second transmission shaft 1412 and the third axial hole 1424. When the driving handle 142 moves in the direction toward the support rod 12 to the state where the first transmission shaft 1411 penetrates the second axial hole 1423, the driving tooth is engaged with the transmission tooth. At this time, the driving handle 142 can drive the screw rod 141 to rotate and adjust the axial position of the screw rod 141; and when the driving handle 142 moves in the direction away from the support rod 12 to the state where the first transmission shaft 1411 disengages from the second axial hole 1423 and enters the first axial hole 1422, the driving tooth is disengaged from the transmission tooth. At this time, the driving handle 142 can rotate and adjust the angle relative to the screw rod 141 so as to adjust the first elevation scale line 1421 to a vertical state, which is convenient for precise elevation positioning.

[0038] Preferably, the screw rod 141 further comprises a threaded segment 1413 and a plug 1414 respectively arranged at two axial ends of the transmission shaft, the threaded segment 1413 is threadedly connected with the threaded hole, the diameter of the threaded segment 1413 is larger than the diameter of the first transmission shaft 1411 so as to form a limiting step on the end surface of the threaded segment 1413 facing the first transmission shaft 1411, the limiting step is used to abut against a side of the driving handle 142 facing the support rod 12 to limit the maximum stroke of the driving handle 142 moving in the direction toward the support rod 12, and the plug 1414 is used to abut against a side of the driving handle 142 away from the support rod 12 to limit the maximum stroke of the driving handle 142 moving in the direction away from the support rod 12. The threaded segment 1413 and the plug 1414 are used to limit the two ends of the driving handle 142 in the lateral movement direction respectively to prevent the driving handle 142 from loosening.

[0039] Preferably, the support rod 12 is provided with a second elevation scale line along its height direction (not shown in the figure, the same below), and the second elevation scale line indicates the installation height of the limit sleeve 13 on the support rod 12, which can also quickly determine the support height of the support assembly 15, thereby facilitating the adjustment of the state of the leveling member 2.

[0040] Preferably, the locking assembly 14 is disposed below the supporting assembly 15 so that there is no shielding structure above the supporting assembly 15, thereby preventing the locking assembly 14 from interfering with the arrangement of the leveling member 2, and further improving applicability.

[0041] Preferably, the base 11 is configured as a flat plate structure in the shape of a right-angled sector, and the installation position of the base 11 can be quickly located through two right-angled sides, and the edge structure outside the two right-angled sides is configured as an arc edge, which can reduce edges and corners and improve safety. Moreover, compared with the use of a polygonal structure, it is only necessary to ensure the straightness of the two right-angled sides, which is more convenient for processing and forming.

Secondly, since the support assembly 15 is configured as a disc-shaped support structure, it can support the leveling member 2 in any direction, and there is no need to accurately adjust the support angle during use, which is more convenient to use and effectively improves the paving efficiency and quality.

[0043] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
