[0032] Embodiment 1

[0033] Please refer to Figures 1 - 4 , this embodiment provides a plumb bob that can store the suspension wire and improve the convenience of use.

[0034] In this embodiment, the plumb bob includes a plumb body 10, a suspension line 20, a storage cylinder 30 and a storage rod 40. Among them, the storage cylinder 30 is screwed into the assembly hole 11 on the plumb body 10. The storage cylinder 30 defines a polygonal inner cavity 31. End caps 33 are fixedly connected to both ends of the inner cavity 31. A circular adjustment groove 32 is provided in the inner cavity 31. The storage rod 40 is inserted into the storage cylinder 30. A limiting plate 41 adapted to the outer shape of the inner cavity 31 is fixedly connected to the storage rod 40. A compression spring 42 is provided between the limiting plate 41 and the end cap 33. The limiting plate 41 is pushed away from the adjustment groove 32 by the compression spring 42. The limiting plate 41 is configured to be able to rotate in the adjustment groove 32. One end of the suspension line 20 is fixedly connected to the side wall of the inner cavity 31, and the other end passes through the storage rod 40 and is fixedly connected to the assembly hole 11.

[0035] In this embodiment, by pushing the storage rod 40, the limiting plate 41 is moved into the adjustment groove 32. At this time, rotating the storage rod 40 can wind the suspension line 20 around the storage rod 40, thereby realizing the storage of the suspension line 20 and improving the convenience of use.

[0036] In this embodiment, the assembly hole 11 is provided on the end face of the plumb body 10 and is coaxially arranged with the plumb body 10. A hook for connecting the suspension line 20 is fixedly connected to the bottom of the assembly hole 11. The suspension line 20 is coaxially arranged with the plumb body 10.

[0037] In addition, the storage cylinder 30 is configured as a cylindrical shape. The storage cylinder 30 can be screwed into the interior of the assembly hole 11. The inner cavity 31 of the storage cylinder 30 is configured as a square in cross section, and the center of the square is located on the axis of the storage cylinder 30. The end cap 33 is configured as a square block adapted to the outer shape of the inner cavity 31. The end cap 33 is adhesively connected to both ends of the inner cavity 31 to close the inner cavity 31. A through hole for the storage rod 40 to pass through is provided on the end cap 33. The adjustment groove 32 is provided in the inner cavity 31 between the two end caps 33. The adjustment groove 32 is a circular groove with a closed-loop structure. The adjustment groove 32 is coaxially arranged with the storage cylinder 30, and the adjustment groove 32 is arranged near the end cap 33 and is arranged in one-to-one correspondence with the end cap 33, that is, two adjustment grooves 32 are provided in the inner cavity 31.

[0038] In addition, the storage rod 40 is configured as a longitudinally elongated circular rod. The storage rod 40 is inserted into the interior of the storage cylinder 30 through the through-hole on the end cap 33, and the storage rod 40 is coaxially arranged with the storage cylinder 30. Two limiting plates 41 are fixedly connected to the storage rod 40. The limiting plates 41 are configured as squares adapted to the outer shape of the inner cavity 31. The diagonal of the aforementioned square is equal to the diameter of the adjustment groove 32. The limiting plates 41 are slidably clamped in the inner cavity 31. By using the sliding clamping cooperation between the limiting plates 41 and the inner cavity 31, the rotation of the storage rod 40 can be prevented, so that the storage rod 40 is only allowed to slide along the axial direction of the storage cylinder 30. The limiting plates 41 and the adjustment grooves 32 are arranged in one-to-one correspondence. A compression spring 42 is provided between the lower limiting plate 41 and the lower end cap 33. The compression spring 42 is integrally sleeved outside the storage rod 40. Under the elastic thrust of the compression spring 42, the limiting plate 41 is located above the corresponding adjustment groove 32, and the upper limiting plate 41 abuts against the upper end cap 33.

[0039] It should be noted that when the storage rod 40 is pushed into the interior of the storage cylinder 30 by a set distance, the compression spring 42 is further compressed, and the limiting plate 41 moves into the adjustment groove 32. At this time, the limiting plate 41 can rotate inside the adjustment groove 32, so that the storage rod 40 can rotate inside the storage cylinder 30, thereby realizing the storage of the suspension line 20.

[0040] In this embodiment, a wire hole for passing the suspension line 20 is provided at the axis of the storage rod 40. The wire hole communicates with the guiding hole on the side wall of the storage rod 40. The guiding hole is arranged radially along the storage rod 40. A hook for connecting the suspension line 20 is also fixedly connected to the side wall of the inner cavity 31. The hook corresponds to the guiding hole. One end of the suspension line 20 is fixed to the hook on the side wall of the inner cavity 31, and the other end passes through the guiding hole and the wire hole and then extends out from the lower end face of the storage rod 40 and is fixed to the hook in the assembly hole 11.

[0041] It should be noted that after the suspension line 20 is led out from the guiding hole, it extends radially along the storage rod 40 and is connected to the hook on the side wall of the inner cavity 31.

[0042] When storing the suspension line 20, first push the storage rod 40 into the interior of the storage cylinder 30 until the limiting plate 41 moves to the adjustment groove 32, and then rotate the storage rod 40 relative to the storage cylinder 30. The suspension line 20 will be pulled into the interior of the storage cylinder 30 and wound around the storage rod 40. After the suspension line 20 is stored, then screw the storage cylinder 30 into the assembly hole 11 on the plumb bob 10, which is more convenient to carry.

[0043] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present application. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present application.
