[0017] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0018] Example

[0019] The present embodiment describes a construction settlement observation device, such as Figures 1 to 3 As shown, it includes a mounting plate 1, which is a rectangular structure with mounting holes communicating with each other on the left and right at its four corners. During installation, four screws are passed through the mounting holes to fix it on the building. A fixing sleeve 8 is vertically arranged on the right side of the mounting plate 1. The fixing sleeve 8 is connected to the mounting plate 1 through a connecting plate 2. During production, the three can be connected by welding.

[0020] like Figure 1 and Figure 3As shown, a freely rotatable rotating sleeve 7 is arranged in the fixed sleeve 8, and limit rings are respectively arranged on the upper and lower ends of the rotating sleeve 7, and the two limit rings are respectively located at the upper and lower ends of the fixed sleeve 8, and the limit rings and the rotating sleeve 7 are integrally formed. When in use, the fixed sleeve 8 is independently sleeved in the middle of the rotating sleeve 7 and is located between the two limit rings, so that the rotating sleeve 7 can only rotate in the fixed sleeve 8, but cannot move up and down; the upper end of the rotating sleeve 7 passes through the fixed sleeve 8 and is fixed with a rotating member driving it to rotate; the rotating member includes a rotating disk 9, which is located directly above the rotating sleeve 7, and the limit ring located above is connected to the rotating disk 9 by at least two connecting rods; the adjusting tube 11 independently passes through the middle of the rotating disk 9; when in use, the rotating sleeve 7 is driven to rotate by rotating the rotating disk 9; in addition, a handle can be directly fixed on the upper end of the rotating sleeve 7 to facilitate the rotation of the rotating sleeve 7;

[0021] An adjusting tube 11 is installed inside the rotating sleeve 7, an outer wall of the adjusting tube 11 is provided with an external thread, an inner wall of the rotating sleeve 7 is provided with an internal thread that is threadedly matched with the external thread, a limiting plate 3 is fixed to the bottom of the connecting plate 2, a limiting groove is vertically provided on the outer wall of the adjusting tube 11, and the limiting end of the limiting plate 3 is located in the limiting groove; when in use, the rotating sleeve 7 is rotated by the turntable 9, the inner wall of the rotating sleeve 7 is threadedly matched with the outer wall of the adjusting tube 11, and when the rotating sleeve 7 rotates and the adjusting tube 11 is restricted from rotating by the limiting plate 3, the adjusting tube 11 moves up and down;

[0022] like Figure 1As shown, a sedimentation rod 4 is independently installed in the regulating tube 11, the upper end of the regulating tube 11 is closed, and scale lines distributed from bottom to top are arranged on the outer wall of the sedimentation rod 4; when marking, the lowest scale line is taken as the "0" scale, and the shorter the length of the upper end of the sedimentation rod 4 in the regulating tube 11, the farther the "0" scale is from the lower end of the regulating tube 11, and conversely, when the sedimentation rod 4 shrinks into the regulating tube 11, the closer the "0" scale is to the lower end of the regulating tube 11; a limiting block 12 is fixed to the upper end of the sedimentation rod 4, and the lower end of the regulating tube 11 is connected to an end cap 6 that closes the limiting block 12 in the regulating tube 11, and the end cap 6 is connected to the lower end of the regulating tube 11 by threads, and a through hole for the sedimentation rod 4 to pass independently is opened at the center of the end cap 6, and the end cap 6 The limit block at the upper end of 4 is enclosed in the adjusting tube 11, mainly to prevent the settlement rod 4 from falling off from the adjusting tube 11; the lower end of the settlement rod 4 is independently fixed with a bottom plate 5 through the through hole; the bottom plate 5 increases the contact area between the lower end of the settlement rod 4 and the ground, preventing the settlement rod 4 from sinking into the ground due to long-term contact with the ground, affecting the observation of settlement; a spring 10 is provided between the settlement rod 4 and the inner top of the adjusting tube 11 to push the settlement rod 4 against the ground, one end of the spring 10 is against the inner fixed part of the adjusting tube 11, and the other end is against the limit block 12, and the elastic force of the spring 10 makes the bottom plate 5 fit closely with the ground, and when the ground settles, the settlement rod 4 will also move downward; in addition, a spring sheet can be used to replace the work of the spring 10 to apply a downward thrust to the settlement rod 4.

[0023] like Figure 2 As shown, an indicator plate pointing to the scale line is fixed at the bottom of the end cover 6; an arrow is engraved on the indicator plate, and the arrow points to the scale line, so that the observer can read the value on the scale line easily.

[0024] In addition, in order to load the rotating sleeve 7 into the fixed sleeve 8, the fixed sleeve 8 can be divided into two equal halves during production, wherein the fixed sleeve 8 on the left half is fixed to the connecting plate 2, and the fixed sleeve 8 on the right half can be removed. After the rotating sleeve 7 is placed into the fixed sleeve 8, the other half of the fixed sleeve 8 is closed and locked together by screws or clamps. When connecting, a positioning component can be set at the joint of the two to facilitate positioning when the two are spliced.

[0025] In actual use, when the spring 10 is in a natural state and the base plate 5 just fits against the ground, the mounting plate 1 is fixed to the wall of the building. At this time, the value of the scale line pointed to by the arrow on the indicator sign is greater than the "0" scale. Then the turntable 9 needs to be rotated to drive the adjusting tube 11 to move downward through the rotating sleeve 7. At the same time, the spring 10 is compressed. Since the lower end of the settlement rod 4 has been against the ground and the spring 10 at the upper end is constantly compressed, the position of the settlement rod 4 remains unchanged, but more of the upper part is retracted into the adjusting tube 11. The smaller the distance between the "0" scale and the indicator sign, until the arrow on the indicator sign just points to the "0" scale of the scale line, stop the rotation of the turntable 9, complete the alignment of the "0" scale with the arrow on the indicator sign (observation point), which is more conducive to later observation and value reading.
