Technical Field

[0001] The utility model relates to the technical field of building construction line springing, in particular to a line springing device used in building construction. Background Art

[0002] Marking is a construction method. The specific operation method is: use an ink-soaked line, two people each hold one end and then mark it on the ground or wall. It is used to determine the horizontal or vertical line, or as a reference line for wall construction.

[0003] The existing line-drawing devices used in construction are all used to draw lines. Since most of the lines are made of cotton lines, during the line-drawing process, the position of the cotton lines cannot be limited by the line outlet, and friction will occur between the cotton lines and the line outlet. When the friction times are too many, the cotton lines will be worn out and broken, resulting in the need for workers to frequently replace the cotton lines, thereby affecting the work efficiency of the workers.

The setting of the threaded rod plays an effect of driving the movable plate to move on the surface of the slide rod.

[0008] Preferably, a second limiting roller is rotatably connected between the slider and the movable plate, and the outer wall surfaces of the second limiting roller and the first limiting roller are both provided with wire grooves. The setting of the movable plate plays an effect of driving the second limiting roller to move.

[0009] Preferably, a winding device is provided on one outer wall surface of the storage box, the winding device comprising a transverse groove, the transverse groove being formed on one outer wall surface of the storage box, a movable plate being slidably connected to the interior of the transverse groove, a support plate being fixedly mounted on one outer wall surface of the storage box, an electric telescopic rod being fixedly mounted on the surface of the support plate, the output end of the electric telescopic rod being fixedly connected to the movable plate.

[0012] 1. In the utility model, an auxiliary device is provided. When the device needs to be used, the motor is started first. The motor starts to drive the threaded rod to rotate. The rotation of the threaded rod drives the movable plate to move on the surface of the slide rod. The movable plate moves on the surface of the slide rod to drive the second limiting roller to move. The movement of the second limiting roller drives the slider to move on the surface of the vertical rod. At the same time, the second limiting roller moves to make itself close to the first limiting roller. When the second limiting roller moves to a suitable position, the motor is turned off. Then the staff pours ink onto the sponge block through the ink inlet tube. Then the staff pulls the pull ring. The movement of the pull ring will pull the cotton thread out of the through hole. At this time, the ink will be absorbed by the cotton thread In addition, since the cotton thread will be limited between the first limiting roller and the second limiting roller during movement, the first limiting roller and the second limiting roller will rotate when the cotton thread is pulled out, thereby reducing the friction of the cotton thread during movement. At the same time, the wire groove can play a limiting role. Then the staff will fix the pull ring at the line drawing position, and pull the cotton thread upward and release it according to the line drawing requirements, thereby completing the corresponding line stretching operation. Through the cooperation of the above structure, the friction of the cotton thread during movement is reduced, thereby reducing the friction loss and breakage of the cotton thread, avoiding the need for staff to frequently replace the cotton thread during work, and thus improving the work efficiency of the staff.

[0013] 2. In the utility model, a winding device is provided. When the line is stretched, the electric telescopic rod is started first. The electric telescopic rod starts to drive the movable plate to move inside the transverse groove. The movable plate moves inside the transverse groove to drive the rack to move. The rack moves and engages with the gear, thereby causing the gear to rotate. The rotation of the gear drives the rotation of the rotating shaft. The rotation of the rotating shaft drives the rotation of the winding roller. The rotation of the winding roller rewinds the cotton thread. Through the cooperation of the above structure, the purpose of automatically winding the cotton thread is achieved, and the convenience of the device during use is further improved.
