Detailed implementation manners
[0032] The following is a further detailed description of the present application in conjunction with the attached Figures 1-5 drawings.
[0033] The embodiment of the present application discloses a building engineering survey and setting-out device, as Figure 1 shown in Figure 2As shown in the figure, it includes a support base 1, a wire pay-off box 2 and a laser emitter 3. A circular rotating groove 4 is opened in the upper end surface of the support base 1 in the vertical direction. A rotating block 5 is rotatably arranged in the rotating groove 4. The rotating block 5 is in a cylindrical shape. A resisting block is fixedly welded to the top of the rotating block 5. The resisting block is also in a cylindrical shape. The diameter of the resisting block is larger than that of the rotating block 5 and is integrally formed with the rotating block 5. The resisting block slides on the upper surface of the support base 1. The resisting block is provided with a fixing member for restricting the rotation of the rotating block 5. The fixing member is a bolt. The bolt penetrates through the resisting block and abuts against the surface of the support base 1. The wire pay-off box 2 is detachably connected to the rotating block 5. The laser emitter 3 is fixedly installed on the upper end surface of the wire pay-off box 2. A wire outlet hole 6 for the cotton thread 66 to pass through is opened on the side wall of the wire pay-off box 2. The laser emitting head on the laser emitter 3 is parallel to the wire outlet hole 6, and the laser ray can play a guiding role for the marking line.
[0034] As Figure 1 shown, on one side of the support base 1 away from the wire pay-off box 2, there is an adjusting assembly 7 for adjusting the height of the support base 1. The adjusting assembly 7 includes four first support rods 48 and four second support rods 49. The four first support rods 48 and the four second support rods 49 are arranged in one-to-one correspondence. The first support rod 48 slides vertically in the second support rod 49. The first support rods 48 are evenly distributed and fixedly welded to the lower end surface of the support base 1. A plurality of connection holes 51 are arranged vertically on the side wall of the first support rod 48. A plug rod 50 slides horizontally on the top side wall of the second support rod 49. The plug rod 50 is inserted into the connection hole 51 to fix the first support rod 48 and the second support rod 49. Thus, the height of the wire pay-off box 2 can be adjusted according to the position of the marking line. The bottom of the second support rod 49 is fixedly connected with a universal wheel 52, and the universal wheel 52 facilitates the staff to move the support base 1.
[0035] As Figure 1 and Figure 2As shown, a plurality of suction cups 59 are fixedly installed on opposite sides of the outer side wall of the wire dispensing box 2, and the suction cups 59 can adsorb on the wall surface. A slot 53 is vertically formed on the upper end surface of the rotating block 5, and the bottom of the wire dispensing box 2 is inserted into the slot 53. A guiding groove 54 is vertically formed on the inner wall of the slot 53. A guiding block 55 is fixedly welded on the side wall of the wire dispensing box 2, and the guiding block 55 slides vertically in the guiding groove 54. A storage groove 56 is horizontally formed on the inner wall of the guiding groove 54. An abutting block 65 slides horizontally in the storage groove 56. A second spring 57 is horizontally arranged in the storage groove 56. The two ends of the second spring 57 are respectively fixedly welded to the inner wall of the storage groove 56 and the abutting block 65. Fourth inclined surfaces 58 are arranged on the upper and lower side surfaces of the end of the abutting block 65 away from the second spring 57, and the guiding block 55 abuts against the fourth inclined surfaces 58. When it is necessary to mark lines at a higher position in the house and the height of the support seat 1 is insufficient for support, at this time, the staff takes out the wire dispensing box 2 from the rotating block 5. The staff pulls the wire dispensing box 2 upward. The guiding block 55 on the bottom side wall of the wire dispensing box 2 pushes the abutting block 65 through the fourth inclined surface 58 to compress the second spring 57 and move away from the guiding block 55, so as to take out the wire dispensing box 2. After that, the staff can adsorb the wire dispensing box 2 on the wall surface through the suction cups 59 according to the position where the lines need to be marked, thus liberating the hands of the staff and facilitating the staff to carry out the line marking operation.
[0036] As Figure 3 and Figure 4 shown, a winding roller 8 for winding the cotton thread 66 is arranged in the wire dispensing box 2. A driving assembly 9 for driving the winding roller 8 to rotate is arranged on the wire dispensing box 2.

The fixing block 67 is frustum-shaped. The fixing block 67 is inserted and in interference fit with the inner wall of the fixing groove 45. A limiting groove 46 is formed on the side wall of the worm 43 along its length direction. A limiting block 47 is fixedly welded in the fixing block 67, and the limiting block 47 slides in the limiting groove 46. When the staff drives the handle 44 to rotate, the fixing block 67 rotates together under the action of the limiting block 47. Subsequently, the staff pushes the fixing block 67 into the fixing groove 45 to be stuck and fix the handle 44, reducing the possibility of the handle 44 rotating randomly.
[0037] AsFigure 3 and Figure 4 As shown in Figure 4 , a first lead screw 11 is rotatably arranged in the winding groove. The first lead screw 11 is parallel to the winding roller 8, and both ends of the first lead screw 11 penetrate and rotate on the opposite inner walls of the unwinding box 2. The unwinding box 2 is fixedly provided with a first guide rod 12. A slider 13 is threadedly connected to the first lead screw 11. The slider 13 slides on the first guide rod 12.

The reset spring 62 is arranged horizontally and the two ends are respectively fixedly welded on the reset block 61 and the connecting frame 60.
[0040] As Figure 3 and Figure 4 shown, and in combination with Figure 5As shown, when paying out the line, the winding roller 8 rotates to drive the one-way wheel 32 to rotate. The one-way wheel 32 drives the first push block 33 to move. Through the first inclined surface 36 and the second inclined surface 37, the first push block 33 moves to push the second push block 34 to move. The second push block 34 moves to stretch the return spring 62 with the reset block 61. The third inclined surface 38 on the second push block 34 abuts against and pushes the bottom of the push rod 27. The push rod 27 moves to push the ink cartridge 29 to move upward, so that the ink outlet of the ink cartridge 29 abuts against the cotton thread 66, and the cotton thread 66 is stained with ink, which is beneficial to improving the clarity of the marking line. When the staff winds up the line, the one-way wheel 32 cannot engage with the teeth 35 of the first push block 33. At this time, the ink cartridge 29 falls under its own gravity away from the cotton thread 66. When the winding roller 8 winds up the line, the one-way wheel 32 cannot drive the second push plate to move. At this time, the second push plate moves away from the push rod 27 under the drive of the return spring 62. At this time, the ink cartridge 29 and the push rod 27 move downward under their own gravity, so that the ink outlet of the ink cartridge 29 is away from the cotton thread 66.
[0041] The implementation principle of the embodiment of the present application is as follows:. Before the line paying-out work, the staff can adjust the height of the support seat 1 and the line paying-out box 2 through the adjusting assembly 7 and rotate the rotating block 5 to adjust the direction of the wire outlet hole 6. Subsequently, the staff drives the worm 43 to rotate by shaking the handle 44. The worm 43 rotates to drive the turbine 42 to rotate, so that the winding roller 8 rotates to pay out the line. When paying out the line, the cleaning plates 18 move away from each other under the drive of the second lead screw 20, away from the cotton thread 66. The ink cartridge 29 moves towards the cotton thread 66 under the push of the moving assembly 31, so that the cotton thread 66 slides on the ink outlet of the ink cartridge 29, reducing the possibility of unclear marking lines caused by insufficient ink in the cotton thread 66 due to decontamination of the cotton thread 66. After the line paying-out is determined, the staff fixes the handle 44 through the fixing block 67. When the staff winds up the line, the cleaning plates 18 move towards each other and abut against each other under the drive of the second lead screw 20, so that the cotton thread 66 passes through between the two rubber blocks 19. The rubber pads can reduce the damage to the cotton thread 66. The dust and other contaminants adhered to the cotton thread 66 fall into the collection box 25 under the clamping and scraping of the two rubber pads. The garbage in the collection box 25 can be taken out for treatment. Thus, not only the surface of the cotton thread 66 is kept clean, but also the cotton thread 66 is prevented from bringing dust and other adhesives into the line paying-out box 2 to contaminate the internal structure of the line paying-out box 2. At the same time, when paying out the line again, it is not affected by the gravity of the adhesives on the cotton thread 66, improving the accuracy.
[0042] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
