Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a plumb bob measuring device for building construction. Background Art

[0002] A plumb bob, also known as a plumb bob, is a simple but unique device made of a wire and a lead weight. Once the plumb bob is suspended, it points vertically downward, precisely to the center of the earth. By comparing it to the plumb line, nearby objects can easily determine whether they are vertical, so it plays an indispensable role in architectural measurement: ensuring that the verticality of a building is up to standard.

[0003] However, in actual operation, when workers move from one fixed point to another for measurement, they sometimes randomly wind and reel the connecting wire, causing the connecting wire to become tangled, which brings inconvenience to the next use. In order to solve this problem, we have specially designed a plumb bob measuring device for construction. This device cleverly combines the inclined hole wheel, hollow limit block and bevel round head, so that workers can obtain a stable intermittent tightening force when reeling the connecting wire in the inner cavity of the rope wheel. This design makes the connecting wire more neat when reeling, improves work efficiency, and also provides convenience for the next use. Utility Model Content

A connecting rod 5 is slidably connected to the inner cavity of the hollow limit block 4. A beveled round head 6 is welded to the bottom end of the connecting rod 5.

The surface of the connecting rod 5 is slidably connected to the inner cavity of the spring 7. A fixed tube 8 is welded to the top end of the hollow limit block 4. The inner cavity of the fixed tube 8 is rotatably connected to a support rod 9. A limit rod 10 is welded to the front side of the support plate 1. The limit rod 1 0 is located obliquely above the hollow limit block 4, the front side of the inclined hole wheel disc 3 is fixedly connected to the rope wheel 11 by bolts, and the front side of the support plate 1 is rotatably connected to the auxiliary guide wheel 12. Through the setting of the auxiliary guide wheel 12, when the plumb bob 13 and the connecting line are recovered and lowered, the connecting line can obtain a smooth supporting force, thereby making the recovery and lowering process of the plumb bob 13 and the connecting line smoother. The auxiliary guide wheel 12 is located on the left side of the rope wheel 11, and the inner cavity of the rope wheel 11 is wrapped with a connecting line. The left end of the connecting line is fixedly connected to the plumb bob 13, and the surface of the connecting line is slidably connected to the inner wall of the auxiliary guide wheel 12. The front side of the support plate 1 is rotatably connected to the auxiliary support plate 14, and the auxiliary support plate 14 is located directly below the plumb bob 13.

[0024] Embodiment 2:

[0025] Figure 1-4The utility model shows a plumb bob measuring device for construction according to an embodiment of the utility model, which comprises: a support plate 1: a straight rod 2 is rotatably connected to the front side of the support plate 1, a slanted hole wheel disc 3 is fixedly connected to the surface of the straight rod 2, a hollow stop block 4 is welded to the front side of the support plate 1, the hollow stop block 4 is located above the slanted hole wheel disc 3, a connecting rod 5 is slidably connected to the inner cavity of the hollow stop block 4, a beveled round head 6 is welded to the bottom end of the connecting rod 5, a spring 7 is welded between the bottom of the hollow stop block 4 and the top of the beveled round head 6, and the surface of the connecting rod 5 is connected to the spring 7. The inner cavity of the spring 7 is slidably connected, the front end of the straight rod 2 passes through the front side of the rope pulley 11 and is fixedly connected with the rocker 15 by bolts, the front side of the rocker 15 is rotatably connected with the sleeve 16, the rear side of the support plate 1 is fixedly connected with the limit plate 17 by bolts, the top of the limit plate 17 is fixedly connected with the handle 18 by bolts, and the bottom of the limit plate 17 is fixedly connected with the limit nail 19. Through the setting of the limit nail 19, when the limit plate 17 and the support plate 1 are fixed on the wall or the surface of the support frame, the process of lowering the plumb bob 13 can be more stable.

[0026] Working principle: when the utility model is used, the user can fix the limit plate 17 to the wall or the surface of the support frame through the limit nail 19 at the bottom of the limit plate 17, and then rotate the auxiliary support plate 14 downward to end the support of the plumb bob 13, and then rotate the support rod 9 to the left, so that the position of the support rod 9 and the limit rod 10 is misaligned, and then pull the support rod 9 to drive the connecting rod 5 and the inclined round head 6 to slide upward. When the position of the support rod 9 is higher than the limit rod 10, the support rod 9 is rotated to the right, so that the support rod 9 is attached to the top of the limit rod 10, and then the position of the connecting rod 5 and the inclined round head 6 is limited, so that the inclined round head 6 is separated from the inclined hole on the surface of the inclined hole wheel disc 3, ending the gathering force on the inclined hole wheel disc 3 and the rope pulley 11, and then rotate the rocker 15 counterclockwise, and then lower the plumb bob 13 to be tested. When the measurement is finished and the connecting line and the plumb bob 13 need to be recovered, the support rod 9 is rotated leftward to disengage the support rod 9 from the top of the limiting rod 10, thereby ending the limiting of the connecting rod 5 and the beveled round head 6, and then the beveled round head 6 falls into the oblique hole on the surface of the oblique hole wheel disk 3 again, and then the rocker 15 is rotated clockwise to drive the rope pulley 11 to reel in the connecting line and the plumb bob 13. At this time, the oblique hole wheel disk 3 in the rotating state, under the action of the oblique hole and the beveled round head 6 on its surface, further pushes the connecting rod 5. At the same time, under the action of the rebound force of the spring 7, downward pressure is applied to the beveled round head 6 and the connecting rod 5, thereby making the beveled round head 6 reciprocate in the oblique hole on the surface of the oblique hole wheel disk 3, so that the rope pulley 11 can obtain an intermittent contraction force, and then the connecting line can be more neat when reeling, which is convenient for the next use.

[0027] To sum up: the plumb bob measuring device for construction drives the rope pulley 11 to reel in the connecting line and the plumb bob 13 by rotating the rocker 15 clockwise. At this time, the connecting rod 5 is pushed under the action of the inclined hole on the surface of the inclined hole disc 3 and the inclined round head 6. At the same time, under the action of the rebound force of the spring 7, the inclined round head 6 is reciprocated and lifted in the inclined hole on the surface of the inclined hole disc 3, so that the rope pulley 11 can obtain an intermittent tightening force, so that the connecting line can be more neat when reeled, which is convenient for the next use.
