Specific embodiments

[0023] The following further describes the present utility model in detail with reference to the accompanying drawings and specific embodiments.

[0024] As Figures 1-7 shown, the scribing device for stadium construction of the present utility model includes: the first rubber strip 1, the second rubber strip 2, the scribing coating 4, and the roller brush device; the first rubber strip 1 and the second rubber strip 2 are parallel and spaced apart and adhered to the stadium ground, and a scribing area 3 is formed between the first rubber strip 1 and the second rubber strip 2; the scribing coating 4 is arranged in the scribing area 3; the roller brush device includes a roller brush 6 and an operating rod 5 detachably connected to the roller brush 6. The roller brush 6 includes bristles 61, a fixed cylinder 62, a mounting shaft 65, and a connecting shaft 67; the bristles 61 are arranged on the outer wall of the fixed cylinder 62; the fixed cylinder 62 is sleeved on the mounting shaft 65 and is connected by a detachable fastener; the mounting shaft 65 is sleeved on the connecting shaft 67, and a bearing is arranged between the mounting shaft 65 and the connecting shaft 67; one end of the connecting shaft 67 is connected to the operating rod 5, and the connecting shaft 67 and the operating rod 5 are connected as an L-shaped integral structure. The fixed cylinder 62, the mounting shaft 65, and the connecting shaft 67 are coaxially matched. The ends of the fixed cylinder 62 and the mounting shaft 65 close to the operating rod 5 are spaced from the operating rod 5. The axial length of the fixed cylinder 62 is greater than or equal to the width of the scribing area 3.

[0025] The usage steps of the scribing device for stadium construction in this embodiment are as follows:

[0026] Step A: Use a triangular stabilizer to cover the two groups of adhesive tapes: the first rubber strip 1 and the second rubber strip 2 on both sides of the ground where scribing is required;

[0027] Step B: Apply the scribing coating 4 to the scribing area 3 between the first rubber strip 1 and the second rubber strip 2;

[0028] Step C: Use the joystick 5 to operate the roller brush 6 to move along the marked area 3, and evenly apply the marking paint 4 between the first rubber strip 1 and the second rubber strip 2 inside the marked area 3;

[0029] Step D: After the marking paint 4 inside the marked area 3 dries, tear off the first rubber strip 1 and the second rubber strip 2 to form the boundary line of the stadium.

[0030] Under the action of the bearing, the mounting shaft 65 and the fixed cylinder 62 can rotate relative to the joystick 5 connected to the connecting shaft 67, so as to roll the marking paint 4 in the marked area 3 on the ground to achieve marking; the fixed cylinder 62 and the mounting shaft 65 are connected by a detachable fastener. When the bristles 61 on the fixed cylinder 62 reach the service life, the fixed cylinder 62 can be detached and replaced, and components such as the mounting shaft 65, the connecting shaft 67, and the joystick 5 can continue to be used, reducing the use cost and maintenance cost.

[0031] In order to achieve the quick installation and positioning of the fixed cylinder 62 and the mounting shaft 65, the roller brush 6 further includes a positioning component. The positioning component is arranged on the mating surface of the fixed cylinder 62 and the mounting shaft 65 and is used to limit the relative rotation of the mounting shaft 65 and the fixed cylinder 62. The positioning component includes a mating positioning strip 63 and a positioning groove 66; a protruding positioning strip 63 is arranged on the inner wall of the fixed cylinder 62; a concave positioning groove 66 is arranged on the outer wall of the mounting shaft 65. In this embodiment, there are four positioning strips 63 and four positioning grooves 66 respectively. The four positioning strips 63 are evenly arranged along the circumferential direction of the fixed cylinder 62, and the positioning grooves 66 are evenly arranged along the circumferential direction of the mounting shaft 65. The widths of the positioning strip 63 and the positioning groove 66 are the same, and the cross-sections both adopt a dovetail structure. Thus, when the fixed cylinder 62 and the mounting shaft 65 are sleeved, the four positioning strips 63 are inserted into the four positioning grooves 66 one by one, restricting the relative rotation of the fixed cylinder 62 and the mounting shaft 65. Applying a tensile force along the axial direction can split the fixed cylinder 62 and the mounting shaft 65. In order to avoid unnecessary splitting of the fixed cylinder 62 and the mounting shaft 65, the two are connected by a detachable fastener. Thus, when splitting is required, the fastening effect of the detachable fastener can be released. On the contrary, after the fixed cylinder 62 and the mounting shaft 65 are fastened by the detachable fastener, the two cannot move relative to each other along the axial direction and cannot be split.

[0032] The rotary brush 6 further includes a protruding annular limiting seat 64; the annular limiting seat 64 is arranged at one end of the mounting shaft 65 close to the operating rod 5; one end of the fixed cylinder 62 close to the operating rod 5 is provided with an inward concave annular step portion that abuts and cooperates with the annular limiting seat 64. The positioning strip 63 extends from one end of the fixed cylinder 62 far from the operating rod 5 to the annular step portion; the positioning groove 66 extends from one end of the mounting shaft 65 far from the operating rod 5 to the annular limiting seat 64. Under the combined action of the annular step portion and the annular limiting seat 64, the mating depth of the fixed cylinder 62 and the mounting shaft 65 is restricted, especially an axial positioning function is achieved, while the positioning groove 66 and the positioning hole achieve a circumferential positioning function, restricting the relative rotation of the fixed cylinder 62 and the mounting shaft 65, thus facilitating the fastening and disassembly of the detachable fastener.

[0033] In this embodiment, the detachable fastener includes a through hole 68, a screw connection hole 69 and a bolt; the mounting shaft 65 is provided with a through hole 68 that penetrates to the inner wall of the fixed cylinder 62, and the inner wall of the fixed cylinder 62 is provided with a screw connection hole 69 that is docked with the through hole 68; the bolt passes through the through hole 68 and is threadedly connected to the screw connection hole 69. When the relative rotation and the mating depth of the fixed cylinder 62 and the mounting shaft 65 are both fixed, the relative positions of the through hole 68 and the screw connection hole 69 are also restricted, aligning the through hole 68 with the screw connection hole 69, which is conducive to the bolt passing through the through hole 68 and connecting with the screw connection hole 69. In this embodiment, four detachable fasteners can be provided, and they are evenly spaced along the circumference of the fixed cylinder 62 or the mounting shaft 65. The inlet end of the through hole 68 is one end of the mounting shaft 65 far from the operating rod 5, and the outlet end is the outer wall of the mounting shaft 65, so that the central axis of the bolt is not parallel to the central axis of the mounting shaft 65 or the fixed cylinder 62, presenting a certain angle.

[0034] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
