Description

Technical Field

[0001] The present application relates to the technical field of road construction equipment, and more specifically, to a road marking machine with a positioning structure. Background Art

[0002] The road marking machine is used to survey and map road traffic safety signs such as zebra crossings, sidewalks, lanes and other road signs on highways and roads.

[0003] The document with the prior art publication number CN217026637U provides a marking machine with a positioning structure for road construction. The marking machine moves the slide plate upward to move the positioning pin out of the groove of the turning handle, and then reverses the turning handle by 90 degrees, so that the turning rod drives the stopper to align with the through hole provided on the limit plate, and the limit block can be moved out of the limit groove through the action of the spring, and then the paint box can be taken out of the placement groove and the paint box can be replenished, which is convenient for the staff to operate; the positioning pin is extended into the groove of the turning handle, so as to prevent accidental touch, thereby preventing someone from accidentally turning the turning handle, causing the limit block to move out of the limit groove and releasing the fixation of the paint box.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, the nozzle of the marking machine is installed on the fixed sleeve and the displacement cannot be adjusted, resulting in poor flexibility.

[0005] In view of the above-mentioned related technologies, the inventor believes that the flexibility and accuracy of the movement and positioning of the nozzle can be improved by providing an adjustable nozzle and cooperating with a positioning component. In view of this, we propose a marking machine with a positioning structure. Utility Model Content
