Description

Technical Field

[0001] This utility model relates to the technical field of ink line devices, specifically a multifunctional chalk line marking and marking device for construction sites. Background Technology

[0002] Chinese patent document CN211137120U discloses an ink fountain for construction line marking, comprising a housing with a line storage cavity and an ink cavity. A first mounting base is connected to the inner wall of the line storage cavity, and a first baffle is threadedly connected to the upper end of the first mounting base via screws. A rotating shaft is disposed inside the line storage cavity, with one end of the shaft movably penetrating through the side wall of the line storage cavity and connected to a turntable. A crank handle is connected to the edge of the side wall of the turntable. The rotating shaft is connected to the side wall of the line storage cavity via bearings. When the ink fountain needs to be used, one person holds the housing, and another person holds a limiting block, gradually increasing the distance between them as the ink line is released. At this time, the rotating shaft rotates accordingly, and the ink line passes under a sponge and picks up ink. This device squeezes the ink in the sponge, resulting in a more ink-laden ink line and a clearer line marking.

[0003] However, in the above-mentioned solutions and existing technologies, the ink line passes through the ink tank of the ink fountain and is dyed by the ink-dyeing sponge block to make the line. Currently, the multi-functional line-laying ink fountain commonly used in construction projects generally uses a single line type, which cannot adjust the line width according to different surface roughness. When using it, the line type needs to be changed frequently or the line needs to be repeatedly laid out, which affects the efficiency of line laying. Improvement and optimization are needed.

[0004] Therefore, this utility model proposes a multi-functional chalk line marking device for construction sites to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a multifunctional chalk line marking device for construction sites to solve the problems mentioned in the background art.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By moving the T-shaped slide plate within the T-shaped groove until one side of the moving plate engages with the inner wall of the ink fountain body, at this point, one side positioning block separates from the positioning slot on the winding roller, while the other side positioning block remains engaged with the positioning slot on the winding roller. This means one side of the winding roller cannot rotate, while the other side unwinds the ink line. When the ink line on the winding roller is pulled out, the spring is compressed, and the spring resets, pushing the winding roller to rotate and automatically rewind the ink line. The operation is simple, and the device can quickly switch and adjust different diameter lines according to different surface roughness for line marking and unwinding operations, reducing the number of repeated line markings and improving line marking and unwinding efficiency.

[0023] Please see Figures 1-6 The present invention provides the following two preferred embodiments:

[0024] Example 1: A multifunctional chalk line release device for construction sites, comprising: a chalk line body 1 and a winding roller 4; the chalk line body 1 has two ink chambers symmetrically arranged at its front end, and fixed shafts 3 are symmetrically fixed on the inner walls of both sides of the chalk line body 1; the winding roller 4 has a circular groove 5 on its side wall, and the end of the fixed shaft 3 is rotatably connected to the center of the circular groove 5; the winding roller 4 is wound with ink thread 6; characterized in that: two winding rollers 4 are symmetrically arranged, the ink thread 6 wound in the two winding rollers 4 has a different diameter, and the ends of the ink thread 6 pass through the two ink chambers 2 respectively; the chalk line body 1 is provided with a release assembly and an auxiliary assembly; the first gear 7 in the release assembly is fixedly arranged on the side wall of the winding roller 4, the spring 8 is arranged in the circular groove 5, the spring 8 is sleeved on the fixed shaft 3, one end of the spring 8 is fixedly connected to the peripheral wall of the fixed shaft 3, and the other end is fixedly connected to the peripheral wall of the circular groove 5; baffles 9 are equidistantly fixed on the side wall of the winding roller 4, and the baffles 9 engage with the spring 8; the winding roller 4 is wound with ink thread 6; The two side walls of the roller 4 are symmetrically and equidistantly provided with positioning slots 10. The drive key shaft 11 is rotatably mounted on the inner wall of one side of the ink fountain body 1, and the other end of the drive key shaft 11 passes through the other side wall of the ink fountain body 1 and is fixedly provided with a handle 12. The center of the second gear 13 is provided with a keyway that is connected to the drive key shaft 11 for transmission. The second gear 13 is meshed with the drive key shaft 11. The second gear 13 is movably mounted on the drive key shaft 11. A T-shaped groove 14 is provided on the bottom wall of the ink fountain body 1. A T-shaped slide plate 15 is movably engaged within the slide groove 14. A fixed plate 16 is fixedly mounted at the end of the T-shaped slide plate 15. A movable plate 17 is symmetrically fixedly mounted on the side wall of the fixed plate 16. A circular hole 18 is provided on the side wall of the movable plate 17 for the drive key shaft 11 to pass through. A positioning block 19 is fixedly mounted on the side wall of the movable plate 17 and engages with the positioning slot 10. A lever 20 is symmetrically fixedly mounted on the side wall of the movable plate 17 and engages with the second gear 13.

[0025] In use, a thin ink thread 6 with a smaller diameter is wound inside the left winding roller 4 of the ink fountain body 1, and a thicker ink thread 6 with a larger diameter is wound inside the right winding roller 4. Moving the fixing plate 16 causes the T-shaped sliding plate 15 to move to the right in the T-shaped groove 14 until the right moving plate 17 engages with the inner wall of the ink fountain body 1. At this point, the positioning block 19 on the right moving plate 17 separates from the positioning groove 10 on the right winding roller 4, while the positioning block 19 on the left moving plate 17 remains engaged with the positioning groove 10 on the left winding roller 4. During this process, the dial plate 20 moves the second gear 13 along the drive key shaft 11. Using the handle 12 to rotate the drive key shaft 11, the angle of the second gear 13 is adjusted so that it engages with the first gear on the side wall of the right winding roller 4. 7. Engagement is used to assist in wire feeding and winding. At this time, the left winding roller 4 cannot rotate, while the right winding roller 4 feeds out the wire. Pulling out the ink thread 6 on the right winding roller 4, it passes through the ink tank 2 and is dyed by the ink sponge block inside. At the same time, during the rotation of the winding roller 4, the spring spring 8 is compressed. After the ink thread 6 on the right winding roller 4 is released, the spring spring 8 returns to its original position and pushes the winding roller 4 to rotate, automatically winding back the ink thread 6. Similarly, the reverse moving fixed plate 16 can be used to unlock the left winding roller 4, allowing ink threads 6 of different diameters inside to be elastically operated. The operation is simple, and the device supports quick switching and adjustment of different diameter wire types for wire feeding and winding operations according to different surface roughness, reducing the number of repeated wire feeding and improving the efficiency of wire feeding and winding.

[0026] Example 2: Based on Example 1, the slot 21 in the auxiliary component is opened on the side wall of the T-shaped slide plate 15, the protruding plate 22 is fixedly set on the bottom wall of the ink fountain body 1, the protruding plate 22 is movably sleeved with the insertion rod 23, one end of the insertion rod 23 is fixedly set with a pull ring, the insertion rod 23 is sleeved with the auxiliary spring 24, the insertion rod 23 is fixedly sleeved with the limit plate 25, the two ends of the auxiliary spring 24 are respectively engaged with the limit plate 25 and the protruding plate 22, the insertion rod 23 is inserted into the slot 21, and the insertion rod 23 is engaged with the side wall of the T-shaped slide plate 15.

[0027] In use, the compressed auxiliary spring 24 pushes the limiting plate 25 to move and push the insertion rod 23. When the insertion rod 23 is inserted into the slot 21, the dial plate 20 moves the second gear 13 between the two first gears 7 inside the ink fountain body 1. At this time, the positioning blocks 19 on the left and right moving plates 17 respectively engage with the positioning slots 10 on the two winding rollers 4 to lock the two winding rollers 4 and prevent the two winding rollers 4 from rotating. When the insertion rod 23 engages with the left or right side wall of the T-shaped slide plate 15, only one side of the winding roller 4 can rotate. The operation is simple and avoids the winding roller 4 from rotating arbitrarily, which would cause the ink line 6 to loosen and be pulled out.
