SUMMARY

[0005] The utility model aims at providing a tire section line drawing marking ruler to solve the problems in the background art.

[0006] To achieve the above object, the utility model provides the following technical scheme:

[0007] A tire section line drawing marking ruler comprises an arc-shaped bottom plate and two arc-shaped rulers connected to both ends of the bottom plate by buckles to form an integral arc, the inner concave side of the arc-shaped ruler is uniformly provided with a plurality of first telescopic teeth, the inner concave side of the bottom plate is uniformly provided with a plurality of second telescopic teeth, and the outer convex side of the bottom plate is provided with a handle in the middle.

[0008] Further, a cavity is formed in the arc-shaped ruler, a plurality of round through holes are uniformly formed in the inner concave side of the arc-shaped ruler, the first telescopic teeth are installed in the round through holes, and the arc-shaped ruler is a PVC flexible ruler.

[0009] Further, the first telescopic teeth are provided with a first spring at one end of the cavity, and the first spring is installed on the inner side of the cavity away from the first telescopic teeth.

[0010] Further, a plurality of cylindrical grooves are uniformly formed in the inner concave side of the bottom plate, and the bottom inner wall of the cylindrical groove is fixedly connected with the bottom of the second telescopic teeth through a second spring.

[0011] Further, the first telescopic teeth and the second telescopic teeth are made of rubber.

[0012] Compared with the prior art, the utility model has the beneficial effects that:

[0013] The utility model discloses a first telescopic tooth and second telescopic tooth surface brush white paint, aligning arc scale with tire pattern, press down, can draw mark line, can accurate draw line position, and the drawing device is basically in accord with the tire appearance, and the telescopic tooth can be well attached tire surface with telescopic tooth collocation, and accurate drawing makes the accurate positioning cutting position.
