[0002] During building construction, it is usually necessary to mark lines in advance to plan the position and direction of construction, so as to avoid the situation that the project is inclined during construction. When marking lines, a special marking tool is usually used to draw white lines on the ground or wall surface.

[0003] The existing marking method usually uses a marking tool to draw straight lines or circular arc lines along a straight plate or a circular plate. However, since the ground or wall surface of the construction site is not necessarily completely smooth, without the use of auxiliary devices, the drawn straight lines are not straight and the drawn circular arc lines are irregular. Therefore, a line marking device is needed to solve this problem. SUMMARY

[0004] To solve the above technical problems, the utility model provides a site line marking device which can assist in the marking process, make the drawn straight lines more straight, and make the drawn circular arc lines more regular.

[0005] The technical solution for achieving the purpose of the utility model is as follows: a site line marking device, comprising a support frame, a line marking assembly is arranged on the support frame, the line marking assembly comprises a rotating shaft and a straight rod, the rotating shaft is rotatably connected to the support frame, the straight rod is fixedly connected to the rotating shaft, a sliding hole is formed in the straight rod, a sliding block is slidably connected in the sliding hole, a line marking pen is arranged on the sliding block, and an auxiliary assembly is arranged on the straight rod and the support frame.

[0006] Preferably, a bottom pad is arranged at the bottom of the support frame, and the bottom pad is made of rubber.

[0007] Preferably, the auxiliary assembly comprises a straight line scale and an angle scale, the straight line scale is arranged on the straight rod, and the angle scale is arranged on the support frame.

[0008] Preferably, the auxiliary assembly further comprises a first magnetic block and a second magnetic block, the first magnetic block is fixedly connected to the support frame, the second magnetic block is fixedly connected to the straight rod, and the first magnetic block and the second magnetic block are attracted to each other when they are close to each other.

[0010] Preferably, the support frame is composed of two connected circular rings, the two circular rings have circular holes, and the rotating shaft is rotatably connected to the inside of the two circular holes.

[0011] Preferably, the first magnetic block and the second magnetic block are in contact with each other, and the straight rod is located at a zero degree scale line on the angle scale.

[0012] Compared with the prior art, the utility model has the following remarkable advantages:

[0013] Firstly, in the utility model, when it is needed to draw a line on the ground or a wall, the first magnetic block and the second magnetic block are attracted to each other, and the straight rod is located at a zero degree scale line on the angle scale, so that when the support frame is placed, the straight rod can be located at a correct initial position by adjusting the support frame to a suitable initial position according to the angle scale on the support frame, and if a straight line is needed to be drawn, the sliding block is only needed to be slid in the sliding hole, so that the line marker moves with the sliding block to draw a straight line on the ground or the wall, and since the sliding block moves along a straight line in the sliding hole, the drawn line is ensured to be a straight line.

[0014] Secondly, in the utility model, the bottom pad is made of rubber, so that when it is pressed against the ground or the wall, a large static friction force can be generated to avoid the support frame from moving greatly during the line drawing process, and the bottom pad has a certain deformation capacity, so that when the ground or the wall is uneven, the bottom pad can be deformed correspondingly when the line marker is pressed against a protrusion on the ground or the wall, so that the line marker can also draw a straight line even if it contacts the protrusion.

[0015] Thirdly, in the utility model, when an arc line is drawn, the initial position of the support frame is only needed to be adjusted, and then the straight rod is rotated, the angle of the arc line can be observed by the corresponding scale on the angle scale, and the radius of the arc can be observed by the straight line scale.

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This utility model provides an improved on-site marking device. The technical solution of this utility model is as follows:

[0024] like Figures 1-3 As shown, a field marking device includes a support frame 1, on which a marking assembly 3 is mounted. The marking assembly 3 includes a rotating shaft 31 and a straight rod 32. The rotating shaft 31 is rotatably connected to the support frame 1, and the straight rod 32 is fixedly connected to the rotating shaft 31. A sliding hole 33 is provided on the straight rod 32, and a slider 34 is slidably connected inside the sliding hole 33. A marking pen 35 is mounted on the slider 34. An auxiliary assembly 4 is jointly mounted on the straight rod 32 and the support frame 1.

[0025] Furthermore, a base pad 2 is provided at the bottom of the support frame 1. The base pad 2 is made of rubber. The rubber material gives the base pad 2 a large static friction force when it is pressed against the ground or wall, so as to prevent the base pad 2 and the support frame 1 on it from moving when marking lines. At the same time, the base pad 2 has a certain deformation capability. When the marking pen 35 is pressed against the protrusion or depression on the ground or wall, the base pad 2 can deform slightly so that the marking pen 35 can move slightly to adapt to the protrusion and depression.

[0026] Furthermore, the auxiliary component 4 includes a linear scale 41 and an angle scale 42. The linear scale 41 is mounted on the straight rod 32, and the angle scale 42 is mounted on the support frame 1. The linear scale 41 is used to observe the length of the line when drawing a straight line, and the linear scale 41 can also be used to observe the radius of the arc when drawing an arc.

[0027] Furthermore, the auxiliary component 4 also includes a first magnetic block 43 and a second magnetic block 44. The first magnetic block 43 is fixedly connected to the support frame 1, and the second magnetic block 44 is fixedly connected to the straight rod 32. When the first magnetic block 43 and the second magnetic block 44 are close to each other, the straight rod 32 can be fixed by the attraction between the first magnetic block 43 and the second magnetic block 44.

[0028] Further, the surface of the marking pen 35 is provided with threads, and a screw hole is formed in the sliding block 34, so that the marking pen 35 is threadedly connected to the sliding block 34, and thus the marking pen 35 can be disassembled and the height of the marking pen 35 can be adjusted, so that the marking pen 35 can be attached to a wall or a floor.

[0029] Further, the support frame 1 is composed of two connected annular rings, and the two annular rings are provided with circular holes, and the rotating shaft 31 is rotatably connected to the inside of the two circular holes.

[0030] Further, when the first magnetic block 43 and the second magnetic block 44 are in contact, the position of the straight rod 32 corresponds to the zero scale line on the angle scale table 42, so that the straight rod 32 can be in the correct initial position by adjusting the initial position of the support frame 1 according to the angle scale table 42 on the support frame 1.

[0031] Specific working method is: when the line needs to be drawn on the floor or the wall, the first magnetic block 43 and the second magnetic block 44 are attracted to each other, and at this time, the straight rod 32 corresponds to the zero scale line on the angle scale table 42, so that the straight rod 32 can be in the correct initial position by adjusting the initial position of the support frame 1 according to the angle scale table 42 on the support frame 1, and at this time, if a straight line needs to be drawn, the sliding block 34 is only needed to slide in the sliding hole 33, so that the marking pen 35 moves with the sliding block 34 to draw a straight line on the floor or the wall, and since the sliding block 34 moves in the sliding hole 33 along a straight line, the drawn line can be ensured to be a straight line, the bottom pad 2 is made of rubber, so that when the bottom pad 2 is pressed against the floor or the wall, a large static friction force can be obtained to avoid that the support frame 1 moves greatly during the drawing process, and the bottom pad 2 has a certain deformation capacity, so that when the floor or the wall is uneven, the bottom pad 2 can deform correspondingly when the marking pen 35 is pressed against the protrusions on the floor or the wall, so that the marking pen 35 can also contact the protrusions, and the finally drawn line can be a straight line in a straight view, and when an arc line needs to be drawn, the initial position of the support frame 1 is only needed to be adjusted, and then the straight rod 32 is rotated, the angle of the arc line can be observed by the corresponding scale on the straight rod 32 on the angle scale table 42, and the radius of the arc can be observed by the straight line scale table 41.
