Background Technology

[0002] In current construction, tasks such as ground area demarcation, safety passage marking, and traffic flow guidance all rely on manual application of positioning tape. Traditional methods suffer from the following technical drawbacks: 1) Operators must maintain a bent-over posture throughout the tape positioning and pressing process, leading to a significant rate of physical fatigue accumulation; 2) Manual application depends on the operator's experience and stability, making it difficult to ensure consistent lines. Therefore, this paper researches and improves upon existing structures and shortcomings to provide a construction marking device with greater practical value. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0023] As attached Figure 1 To be continued Figure 5 As shown:

[0024] This utility model provides a construction marking device, including a base beam 1, a vertical beam 2 obliquely connected to the top of the base beam 1, a handle 3 fixedly installed at the top of the vertical beam 2, and fixed plates 4 connected to both sides of the vertical beam 2. Each fixed plate 4 has a through hole in its center. A bidirectional hollow screw 5 is rotatably connected to one side of the fixed plate 4 outside the through hole. A hollow limiting post 6 is fixedly installed on one side of the fixed plate 4 outside the bidirectional hollow screw 5. A connecting post 7 is slidably connected to the other side of the fixed plate 4 inside the through hole. One side of the connecting post 7 extends into the interior of the bidirectional hollow screw 5 and is slidably connected to the bidirectional hollow screw 5. The other side of the connecting post 7 is fixedly connected to the vertical beam 2. Three sets of arc-shaped abutment plates 8 are connected to the outer side of the bidirectional hollow screw 5 through an adjustment mechanism.

[0025] The adjustment mechanism includes a movable ring 9 threadedly connected to the outside of the two sets of bidirectional hollow screws 5. The outer side of the hollow limiting post 6 is provided with three sets of waist-shaped grooves corresponding to the arc-shaped abutment plate 8. The outer side of each movable ring 9 is provided with three sets of connecting blocks 10. One end of each connecting block 10 extends to the outside of the corresponding waist-shaped groove and is hinged to a connecting rod 11. One end of each of the two sets of connecting rods 11 on the same side is hinged to a connecting block 12. One end of each connecting block 12 is fixedly connected to one side of the arc-shaped abutment plate 8. One end of each bidirectional hollow screw 5 is fixedly installed with a handwheel 13, which enables the three sets of arc-shaped abutment plates 8 to extend and retract radially synchronously, ensuring the stability of the tape clamping. The waist-shaped grooves can also limit the movement range of the connecting blocks 10. At the same time, the design of the handwheel 13 replaces the traditional wrench tool for adjustment, allowing one person to complete the adjustment operation with one hand.

[0026] The adjustment mechanism further includes a fixing column 14 installed on one side of the three sets of arc-shaped abutment plates 8. One side of the fixing plate 4 is provided with a waist-shaped groove that matches the fixing column 14. The fixing column 14 is slidably connected inside the waist-shaped groove. One end of the fixing column 14 is provided with a limiting plate 15. One end of the limiting plate 15 is in contact with the fixing plate 4, so that the arc-shaped abutment plate 8 moves along a preset path and avoids it from deviating. At the same time, the setting of the limiting plate 15 can prevent the fixing column 14 from falling out of the waist-shaped groove and improve the stability of the arc-shaped abutment plate 8 in the working state.

[0027] In this arrangement, each of the two sets of fixed disks 4 is equipped with a fixed ring 16 on one side of the opposite side. The fixed ring 16 has a limit block 17 fixedly installed on both sides of its interior. The outer side of the connecting column 7 is provided with a limit groove corresponding to the limit block 17. The limit block 17 is slidably connected inside the limit groove to prevent the fixed disk 4 from rotating relative to the connecting column 7 when it moves, and to ensure that it always moves along the axial direction.

[0028] The connecting post 7 has a scale line 18 on one side. The fixing ring 16 is threaded with a Phillips head bolt 19 on the outer side of the fixing ring 16 and on the opposite side of the scale line 18. One end of the Phillips head bolt 19 passes through the fixing ring 16 and is rotatably connected to a rubber brake block. One end of the rubber brake block is fastened to the connecting post 7. The scale line 18 can provide a visual axial displacement parameter, so as to facilitate adjustment to a suitable position. The Phillips head bolt 19 can be manually tightened to fix the fixed ring 16 and the connecting post 7 after the length has been adjusted, so as to prevent movement during the marking process.

[0029] The vertical beam 2 is rotatably connected to both sides of the guide roller 20, and the bottom beam 1 is rotatably connected to both sides of the bottom beam 1. The guide roller 20 can straighten the tape and improve work efficiency. The pressure roller 21 can provide smooth movement guidance, so that it can automatically press the tape during movement, replacing manual bending and pasting, and improving the stability of the device.

[0030] A fixing plate 22 is installed on one side of the bottom beam 1, and a push plate 23 is installed at an angle on one side of the fixing plate 22 to facilitate the removal of stones and other impurities that appear in front of the device, thereby improving the marking effect.

[0031] The working principle of this embodiment:

[0032] In use, first turn the Phillips head handle bolt 19 to loosen the fixing ring 16 on one side of the fixing plate 4 from the connecting post 7. Then, according to the required width of the marking, move the fixing plate 4 to the appropriate position along the direction of the scale line 18 on one side of the connecting post 7. Next, reverse the Phillips head handle bolt 19 to tighten the connecting post 7 and the fixing ring 16. Then, place the inner ring of the tape on the outside of the three sets of arc-shaped abutments 8 and turn the handwheel 13 to drive the bidirectional hollow screw 5 to rotate. Because the bidirectional hollow screw 5 has two sections of rotation direction... The reverse thread drives the moving rings 9 on both sides of the bidirectional hollow screw 5 to move relative to each other along the waist-shaped groove 2 on the outside of the hollow limit post 6. With the cooperation of multiple sets of connecting rods 11, connecting block 10 and connecting block 22, the three sets of arc-shaped abutment plates 8 on the same side fix the tape. Then, the non-adhesive side of the tape is wrapped around the guide roller 20 and the adhesive side is placed on the ground. Then, the construction worker holds the handle 3 and pushes the device forward. At the same time, the pressure rollers 21 on both sides of the bottom beam 1 roll the tape on the ground to ensure that it is compacted.

[0033] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
