DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Refer to the instruction manual Figure 1-5 A construction laying-out tool according to an embodiment of the utility model comprises a measuring tape steel bar 1, a transverse groove 3 is provided in the middle of the measuring tape steel bar 1, the number of the transverse grooves 3 is set to be multiple, and the multiple transverse grooves 3 are arranged in sequence and are equidistantly distributed, a positioning portion 4 is fixedly installed at one end of the transverse groove 3, a toggle plate 5 is fixedly installed at one end of the positioning portion 4 in a sunken shape, the toggle plate 5 is arranged in the inner cavity of the transverse groove 3, and a toggle portion 6 is fixedly installed at one end of the toggle plate 5 in a convex shape;

[0027] A liquid storage cotton for absorbing ink is fixedly installed at the bottom of the toggle plate 5, wherein the liquid storage cotton structure includes a cotton strip or a cotton thread or an overall coating, and the surface of the tape measure steel bar 1 is provided with scale lines for measuring length;

[0028] It should be further explained that by combining the structure of the tape measure with the line-laying and line-elasticating structures, the effect of facilitating line-laying at multiple angles is achieved. First, the material of the tape measure steel bar 1 is the same as that of the tape measure, which has good resilience. The tape measure steel bar 1 is bent so that the tape measure steel bar 1 is embedded in the yin-yang corners, and then the positioning cross bar 7 is pulled out of the inner cavity of the slot 9. The toggle part 6 is toggled to make the toggle plate 5 bounce up and down with the positioning part 4 as the circle. The liquid storage cotton at the bottom of the toggle plate 5 can achieve the effect of rapid fixed-point marking near the yin-yang corners, and at the same time, it can also achieve the effect of tape measurement, thereby improving the actual measurement and marking efficiency.

[0029] In addition, the materials of the toggle plate 5 and the measuring tape 1 can be set to be consistent. In this way, when bending the measuring tape 1, if the position of the positive and negative angles is exactly in the middle of the toggle plate 5, the measuring tape 1 can be bent together with the toggle plate 5. In addition, directly pressing the toggle plate 5 can also achieve the purpose of marking the line.

[0030] A positioning cross bar 7 is fixedly installed at one end of the toggle portion 6, and the cross section of the tape measure steel bar 1 is arranged in a semicircular shape. Figure 5 As shown, slots 9 are respectively provided on both sides of the measuring tape steel bar 1, and spherical clamping blocks 8 are fixedly installed at both ends of the positioning cross bar 7. The two ends of the positioning cross bar 7 are respectively inserted into the two slots 9, and the spherical clamping blocks 8 are used to allow the positioning cross bar 7 to form a clamping effect. The function of this solution is to position the toggle plate 5 and improve the convenience of using and fixing the toggle plate 5.

[0031] As a further solution of the present invention, a winding mechanism is installed on one side of the measuring tape steel bar 1, and the winding mechanism includes an outer frame 10 and an outlet portion 12, the outlet portion 12 is located on one side of the bottom of the outer frame 10, and a frame cover plate 11 is installed on one side of the outer frame 10 by bolts; an annular frame 13 is fixedly installed in the middle of the inner cavity of the outer frame 10, an outlet portion 2 14 is opened at the top and bottom of the annular frame 13, a positioning bolt 15 is fixedly installed in the middle of the annular frame 13, a spring component 16 is installed in the inner cavity of the annular frame 13, one end close to the center position of the spring component 16 is fixedly installed in the middle of the positioning bolt 15, and the other end of the spring component 16 passes through the outlet portion 2 14 and the outlet portion 12 and is fixedly connected to one end of the measuring tape steel bar 1;

[0032] It should be noted that the winding principle of the measuring tape is simulated by the spring element 16 , so that it is used in the measurement and laying out of the inner and outer corners, thereby improving the convenience of winding and using the measuring tape steel bar 1 .

[0033] like Figure 3 As shown, a spring telescopic rod 17 is installed at the top of the inner cavity of the outlet portion 12, wherein the spring telescopic rod 17 includes a fixed cylinder, a sliding cylinder and a spring, the sliding cylinder is slidably connected to the inner cavity of the fixed cylinder, and the spring is placed between the fixed cylinder and the sliding cylinder, as shown in FIG. Figure 3As shown, the fixed cylinder is fixedly installed on the top of the inner cavity of the outlet part 12, the sliding cylinder is fixedly installed on the top of the pressure column 18, and the bottom of the sliding cylinder of the spring telescopic rod 17 is fixedly installed with a pressure column 18. The pressure column 18 is pressed on the top of the belt part 20. At least two rotating shafts 19 are rotatably connected on both sides of the inner cavity of the outlet part 12 through bearings, and the outer parts of the multiple rotating shafts 19 are sleeved with the belt part 20. The outer wall of the belt part 20 is provided with a liquid storage cotton 2 for absorbing ink.

[0034] A storage chamber 21 is fixedly installed at the bottom of the inner cavity of the outlet portion 12, and an ink storage cotton 22 is installed in the inner cavity of the storage chamber 21. A notch is opened on one side of the storage chamber 21 close to the belt portion 20, and the belt portion 20 is in contact with the ink storage cotton 22; the tape measure steel bar 1 passes between the pressure column 18 and the belt portion 20, and the pressure columns 23 are fixedly installed at both ends of the pressure column 18, and the pressure column 23 is pressed in the middle of the belt portion 20;

[0035] It should be noted that when the spring telescopic rod 17 pushes the measuring tape bar 1 and the belt portion 20 to move downward, the measuring tape bar 1 is pulled out. At this time, the friction between the measuring tape bar 1 and the belt portion 20 increases, and the belt portion 20 moves in a crawler-like manner on the outer walls of the two rotating shafts 19. Since the outer wall of the belt portion 20 is provided with a liquid storage cotton 2, the ink of the ink storage cotton 22 soaks the belt portion 20, and the ink on the surface of the belt portion 20 soaks the toggle plate 5 at the bottom of the measuring tape bar 1, thereby improving the convenience of the toggle plate 5 for marking the line. In addition, the ink filling work of the ink storage cotton 22 can be directly injected from the position of the outlet portion 12.

[0036] A hook 2 is fixedly installed on the top of the tape measure steel bar 1, and a plurality of connecting brackets 24 are fixedly installed in the inner cavity of the outer frame 10;

[0037] The purpose of setting the hook 2 is to prevent the measuring tape 1 from being rolled into the inner cavity of the outer frame 10 by the force of the spring 16, so as to play a supporting role. The setting of the connecting bracket 24 is to allow a bolt docking point when the frame cover 11 is installed, and to limit the measuring tape 1 in the rolled state, thereby improving the smoothness of the operation of the measuring tape 1.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
