Abstract

A line marker includes a main body and a rod. The main body has a wheel axle set at a bottom of its front side and rear side respectively and the wheel axle has two wheels fitted at its two ends. The main body also includes a paint-spraying base having a positioning hole and a pressing block located below and paralleled the positioning hole with a proper distance for pressing a spraying head to start spraying. The rod is connected with the main body by its lower portion, having a lever fixed at its upper end, connected with a pulling line by its one end. The pulling line has its other end connected with the pressing block to activate it to move. So, controlling the lever to pull the pulling line, the pressing block can be moved to activate the paint spray can to carry out spraying.

Claims

1. A line marker comprising:

a main body provided with a wheel axle installed at a bottom of its front side and rear side respectively, said wheel axle having two wheels pivotally fitted at its two ends, said main body also provided with a paint spraying base located in its front portion that is provided with a positioning hole for accommodating a paint spray can positioned upside down and a pressing block located below and paralleled to said positioning hole with a proper distance correspondingly spaced apart from a spraying nozzle of said paint spray can for pressing said spraying nozzle to carry out spraying, an elastic element installed between one end of said pressing block and said paint spraying base;

a rod connected with said main body by its lower portion and provided with a lever pivotally fixed at its upper end that is connected with a pulling line by its one end, said pulling line connected with one end of said pressing block so as to remove the pressing block to press said spraying nozzle of said paint spray can to start spraying, said lever controlled to keep said pulling line pulled up or released; and

said main body is provided with a Y-shaped frame pivotally fixed at its two sides and connected with said rod by locking with an adjustment bolt, said rod able to be folded to rest in said Y-shaped frame after loosening said adjustment bolt.

2. A line marker as claimed in claim 1, wherein said main body is provided with a carrying base set at its rear portion for storing said paint spray cans and other stuff.

3. A line marker as claimed in claim 1, wherein said paint spraying base is provided with two elastic restricting pieces installed at a top of two sides of said pressing block for clamping said paint spray can stably.

4. A line marker as claimed in claim 1, wherein said main body is provided with an adjusting slot bored longitudinally at two sides of said main body respectively, and said adjusting slots are used to alter the level of said paint spraying base by means of an adjustment bolt movably inserted in said adjusting slots so as to adjust the distance between said paint spray can and the ground.

5. A line marker as claimed in claim 1, wherein said pressing block is formed with an U-shaped groove at one end spaced properly apart from and paralleling said spraying nozzle, and connected pivotally at a bottom of said paint spraying base by the other end.

6. A line marker as claimed in claim 1, wherein said elastic element is an elastic U-shaped steel strip able to automatically push back said pressing block from said spraying nozzle of said paint spray can after releasing said lever.

7. A line marker as claimed in claim 1, wherein said Y-shaped frame is provided with a recess formed at two ends respectively for an adjustment bolt to lock at two sides of said main body, said Y-shaped frame able to be folded downward to rest on said main body after loosening said adjustment bolt.

8. A line marker as claimed in claim 1, wherein said pulling line is wrapped by a plastic tube that is connected fixedly with said lever by its upper end and connected with said pressing block by its lower end.
