Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ink line technology, specifically relating to an ink line for building construction. Background Technology
[0002] In woodworking, drawing straight lines and positioning are crucial steps, requiring craftsmen to have precise measuring and marking tools. The ink line, as a tool that can easily and quickly draw straight lines, perfectly meets this need. An ink line typically consists of four parts: an ink reservoir, a reel, an ink line (including a taper), and an ink stick. Ink lines are commonly used in architectural surveying and house construction. The method of using an ink line is to pull out an ink-soaked line, ensuring it is taut, and then flick the ink to draw a straight line.
[0003] However, the original ink line has some shortcomings. When the ink line is widely used in construction drawing, since the main material of the ink line is cotton thread, the ink contains glue. The residual glue will make the line stick and hard. If the used ink line is not removed, it will not only contaminate the clean line, but if it is used for a long time, the residual glue will make the line stick and hard, resulting in poor line staining effect and a greater possibility of ink dripping. Utility Model Content
[0004] This utility model provides an ink line for building construction to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a chalk line for construction, comprising a line chamber, a connecting plate, a chalk chamber, an erasing component, a clamp, and a chalk line cone. The line chamber and the chalk chamber are fixedly connected by the connecting plate. A line groove is formed inside the connecting plate. A dyeing groove is formed on the side of the chalk chamber. The side of the chalk chamber is fixedly connected to the side of the erasing component. A groove A is formed on the front of the erasing component. An outlet groove and two sliding grooves A are formed on the side of the erasing component. The outlet groove communicates with the groove A. The sliding grooves A are slidably connected to four sliders A. Two sliders A are fixedly connected to one slide plate A. One slide plate A is detachably fixed above the side of the elimination component by two limiting blocks. The side of the slide plate A has a groove B, and the bottom surface of the slide plate A has a slot B. The groove B and the slot B are connected. The groove B and the slider B are slidably connected. The slider B and the slide plate B are fixedly connected. The bottom surface of the slider B has a cutting groove. The cutting groove and the blade are detachably connected. The wire taper is fixedly connected to the clamp. The clamp is clamped and connected to the end of the wire that contacts the outside.
[0006] Preferably, an ink-strapping plate is fixedly connected to the bottom surface of the outlet groove, and an arc groove is formed on the top surface of the ink-strapping plate.
[0007] Preferably, the top and bottom surfaces of the skateboard B are textured.
[0008] Preferably, the wire groove, the dyeing groove, and the outlet groove are located on the same horizontal line.
[0009] Preferably, the materials of the elimination component, the clamp, and the wire tap are all magnetic metals.
[0010] Preferably, the length of the blade is greater than the length of the outlet groove, and the length of the blade is less than the length of the slide plate A.
[0011] Preferably, the length of the groove B is less than the length of the slide plate A.
[0012] Compared with the prior art, the beneficial effects of this utility model are: by moving the two slide plates A toward the middle of the side of the elimination component, the used ink line is clamped in the middle. Since the slide plate B can slide left and right on the slide plate A, the slide plates B on the two slide plates A slide back and forth, thereby eliminating the used ink line. This not only prevents contamination of clean lines, but also prevents problems such as residual adhesive causing the lines to stick and harden, resulting in poor dyeing effect and a greater possibility of ink dripping when used for a long time.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-7 This utility model provides the following technical solution: an ink fountain for construction, comprising a line chamber 1, a connecting plate 2, an ink chamber 3, an ink removal component 4, a clamp 5, and a line cone 6. The line chamber 1 and the ink chamber 3 are fixedly connected by the connecting plate 2. Line 001 is stored in the line chamber 1, and can be replenished if necessary. The connecting plate 2 has a line groove 21 inside. The ink chamber 3 has a dyeing groove 31 on its side. The ink chamber 3 can be disassembled vertically. Two sponges can be tightly pressed together inside the ink chamber 3. Line 001 passes through the two tightly pressed sponges to dye, preventing ink waste. The side of the ink chamber 3 is fixedly connected to the side of the ink removal component 4. The front of the ink removal component 4 has a groove A43, and the side of the ink removal component 4 has an outlet groove 42 and two sliding grooves. Slot A41, outlet slot 42 and slot A43 are connected. Slide A41 and four sliders A45 are slidably connected. Every two sliders A45 are fixedly connected to a slide plate A44. A slide plate A44 is detachably fixed above the side of the elimination component 4 by two limiting blocks 46. Slide plate A44 has a slide groove B441 on its side and a slot B442 on its bottom surface. Slide groove B441 and slot B442 are connected. Slide groove B441 and slider B47 are slidably connected. Slider B47 and slide plate B48 are fixedly connected. Slider B47 has a knife groove 471 on its bottom surface. Knife groove 471 and blade 49 are detachably connected. The wire cone 6 is fixedly connected to the clamp 5. The clamp 5 is clamped and connected to the end of the wire 001 that is in contact with the outside.
[0025] Specifically, to prevent the line 001 from getting too much ink when passing through the ink tank 3, which could cause ink dripping, an ink-strapping plate 421 is fixedly connected to the bottom surface of the outlet groove 42. Since the line 001 is there, an arc groove 4211 is provided on the top surface of the ink-strapping plate 421 to facilitate the line 001 to be pulled on the arc groove 4211 and avoid friction damage to the line 001.
[0026] Specifically, to prevent the user from accidentally slipping the blade 49 out of the groove B441 due to slippage or other reasons, the top and bottom surfaces of the slide plate B48 are textured with grooves 481 to increase friction.
[0027] Specifically, to ensure that line 001 flows smoothly and unobstructed from line tank 1 to ink tank 3 and then to outlet groove 42 of the elimination component 4, the three grooves, line groove 21, dyeing groove 31 and outlet groove 42, are located on the same horizontal line.
[0028] Specifically, since the elimination component 4 of the device has an outlet groove 42 on its side, and the outlet groove 42 is connected to the groove A43, in order to draw a new line, the line 001 is usually clamped from the groove A43 by the clamp 5 and taken out from the outlet groove 42. At this time, the size of the outlet groove 42 is definitely larger than the size of the clamp 5 and the line cone 6. Then the user may face the situation that the line 001, the clamp 5 and the line cone 6 are retracted into the inside of the elimination component 4, which is inconvenient for secondary use. Therefore, the materials of the elimination component 4, the clamp 5 and the line cone 6 are all magnetic metals, so that when not in use, the clamp 5 and the line cone 6 can be magnetically attracted to the outer wall of the elimination component 4.
[0029] Specifically, in actual operation, the two blades 49 need to move up and down to clamp the line 001. Therefore, the length of the blade 49 is greater than the length of the outlet groove 42, and the length of the blade 49 is less than the length of the slide plate A44.
[0030] Specifically, if the length of slide B441 is the same as the length of slide B441, it would mean that the blade 49 would slide out and be removed from both sides. The user would be at risk of being injured by the blade 49. Therefore, the length of slide B441 is less than the length of slide A44.
[0031] The working principle and usage process of this utility model: The user pulls the wire cone 6 to move the wire 001, so that the wire 001 is in a taut state. Then, the user flicks the ink with their finger to draw a straight line. After use, the wire 001 does not need to be pulled back. By releasing the lock of the limiting block 46, the upper sliding plate A44 is moved downward and the lower sliding plate A44 is moved upward, so that the wire 001 is clamped between the two blades 49. Then, the top and bottom surfaces of the two sliding plates B48 are pinched and the two sliding plates B48 are moved in opposite directions to eliminate the used ink line. During this process, if there is any concern that the sliding plate A44 is unstable, it can be fixed by the limiting block 46. After eliminating the used ink line, the clamp 5 is used to clamp the wire 001 from the slot A43 and then taken out from the outlet slot 42. When not in use, the clamp 5 and the wire cone 6 are magnetically attached to the side outer wall of the elimination component 4.
