Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer shall be followed. Where the manufacturers of reagents or instruments are not specified, they are all conventional products that can be purchased commercially.

[0024] like Figure 1-5 As shown, a construction line laying device includes a housing 1. Inside the housing 1, from one end to the other, there are a winding chamber 101, an ink chamber 102, and a line outlet chamber 103 arranged sequentially. A winding roller 2 is rotatably arranged inside the winding chamber for winding ink thread 4. An ink storage sponge 8 is provided inside the ink chamber. A line outlet 104 is provided at the end of the line outlet chamber away from the ink chamber. Specifically, two ink storage sponges can be provided. The ink thread passes between the two ink storage sponges. Ink is added to the ink storage sponge. The ink thread is adhered to the ink when it passes between the two ink storage sponges.

[0025] The bottom outer wall of the shell is provided with a sliding groove, and guide plates 9 are provided on both sides of the sliding groove. The guide plates protrude from the shell and are located below the outlet. The guide plates are provided with guide grooves 901. A pop-line lifting rod 3 is slidably provided between the two guide plates. One end of the pop-line lifting rod is a sliding end and the other end is a lifting end. Guide posts 301 are provided on both sides of the sliding end. The guide posts cooperate with the sliding groove. The lifting end is provided with a lifting part. The bottom of the pop-line lifting rod is provided with a pop-line gap to facilitate the pop-line hitting the ground. The center line of the pop-line gap in the length direction is located in the same vertical plane as the axis of the outlet.

[0026] When in use, pull out the pop-line lifting rod so that the guide post at the sliding end slides into the guide groove of the protruding part of the housing on the guide plate. At this time, the lifting part of the pop-line lifting rod can be lifted, and the guide post rotates in the guide groove.

[0027] The outlet is located near the bottom of the housing, which keeps the ink line low above the ground, making it easier to maintain the accuracy of the chalk line.

[0028] In this embodiment, the lifting part includes a lifting seat 11 fixedly connected to the lifting end. Two first gears 1101 and two second gears 1102 are rotatably mounted on the lifting seat. The two first gears are respectively located above the two second gears. The two first gears mesh with each other and the two first gears mesh with the corresponding second gears.

[0029] Two first gears are fixedly mounted with a line lifting handle 1103, and two second gears are fixedly mounted with a line lifting jaw 1104. The two line lifting jaws cooperate with each other, and the two line lifting jaws are provided with inclined line lifting plates. The bottom ends of the two line lifting plates are arranged opposite each other.

[0030] In the initial state, the housing is placed on the ground, the ink line is pulled out and the pulled-out end of the ink line is fixed. The bottom end of the lifting jaws is lower than the ink line. The two lifting handles are pulled in opposite directions, and the two lifting jaws move closer to each other until they make contact, thus catching the ink line. When the lifting part is lifted, the ink line is also lifted at the same time. The ink line exerts a downward pulling force on the lifting jaws. Slightly loosening the lifting handles allows the two lifting jaws to disengage, and the ink line moves downward to draw a line on the ground. Moreover, during the lifting and snapping of the line, the ink line always remains within the snapping gap. The snapping lifting rod rotates around the guide post in a vertical plane without any deviation in the left or right direction. The lifting and snapping of the line are highly accurate and suitable for high-precision line laying applications.

[0031] In this embodiment, a rotating handle 7 is provided at one end of the winding roller. The rotating handle is located outside the housing. A winding groove is provided on the circumference of the winding roller. A winding roller pressure plate 6 is installed on the housing. One end of the winding roller pressure plate is hinged to the housing, and the other end is snapped into the housing. When it is necessary to change the wire, the winding roller pressure plate 6 can be opened for operation.

[0032] In this embodiment, a cover plate 5 is detachably provided on the top of the ink tank. A pressure plate 12 is hinged inside the ink tank via a pressure plate hinge shaft. One end of the pressure plate is a pressing end, and the other end is a pressing end. The pressing end is located above the ink storage sponge and abuts against the ink storage sponge. A pressure plate hinge shaft 1201 is installed at the bottom of the pressing end. A compression spring is connected between the top of the pressing end and the inner wall of the housing. Under the elastic force of the compression spring, the pressing end presses down on the ink storage sponge so that it makes full contact with the ink line.

[0033] In this embodiment, a guide shaft 13 is rotatably arranged inside the housing behind the winding roller in the winding chamber. Two vertical guide rollers 14 are rotatably arranged inside the housing behind the guide shaft. A gap is left between the two vertical guide rollers for the ink line to pass through. An ink-absorbing sponge mounting ring 15 is installed at the front of the ink tank. An ink-absorbing sponge 16 is provided inside the ink-absorbing sponge mounting ring. When the wire is unwound and it is time to rewind, the ink-absorbing sponge 16 can absorb some of the ink on the passed ink line, so that the ink line wound onto the winding roller is relatively clean.

[0034] In this embodiment, two first horizontal guide rollers 17 are provided in the front part of the outlet compartment inside the housing, and two second horizontal guide rollers 18 are provided in the rear part of the outlet compartment near the outlet. A gap is left between the two horizontal guide rollers and between the two second horizontal guide rollers for the ink line to pass through.

[0035] In this embodiment, the vertical guide roller, the first horizontal guide roller, and the second horizontal guide roller are used to limit the path of the ink line. Specifically, the positions of the vertical guide roller, the first horizontal guide roller, and the second horizontal guide roller can be reasonably set so that the ink line moves in the same vertical plane and minimizes left and right deviation.

[0036] This embodiment also includes an ink line fixing block 8, which has a thread guide groove 801 inside. Two guide plates 802 are provided on both sides of one end of the thread guide groove to accurately define the position of the ink line end. Specifically, an ink line clamping plate is fixed above the thread guide groove of the ink line fixing block by bolts. Figure 1 and Figure 5 The ink line clamping plate is not shown in the image. Figure 2 The ink line pressing plate is displayed in the middle.

[0037] In this embodiment, when the line is lifted, the line lifting rod precisely limits the ink line to prevent deviation. The high line lifting accuracy results in high line snapping accuracy, making it suitable for high-precision line laying applications.

[0038] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
