[0002] Deformation monitoring refers to the process of continuously observing the displacement, settlement, inclination, deflection, cracks and related influencing factors of buildings and their foundations, construction pits or rock and soil within a certain range, and providing deformation analysis and forecasts. Deformation monitoring requires the use of observation markers. Observation markers need to be drilled during installation. Most observation markers are integrated structures and are directly fixed on the wall, making it difficult to replace them. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and functions achieved by the present invention clearer and easier to understand, the technical solutions in the present invention are further described below in conjunction with the accompanying drawings and embodiments.

[0019] See also Figure 1 and Figure 2 As shown, an observation mark for deformation monitoring includes: a rod body 1, a connecting rod 2 and a fixing rod 3 with one end threadedly connected to the side of the wall; the fixing rod 3 is provided with a connecting groove 31 at one end away from the side of the wall, and a positioning block 4 is elastically provided on the inner wall of the connecting groove 31, one end of the connecting rod 2 is connected to the rod body 1, and the other end of the connecting rod 2 extends into the connecting groove 31, and the connecting rod 2 is provided with a positioning groove into which the positioning block 4 extends, and a circular connecting block 5 is also slidably sleeved on the connecting rod 2, and a circular connecting block 5 is integrally formed with a circular ring portion on one side, and the inner wall of the circular ring portion is provided with an internal thread, and the end of the fixing rod 3 provided with the connecting groove 31 is provided with an external thread matching the internal thread.

[0020] The specific structure of the observation mark includes a rod body 1 and an observation cap connected to the top of the rod body 1. A threaded hole is pre-arranged on the side of the wall, and the fixing rod 3 is provided with an external thread that cooperates with the internal thread in the threaded hole. The fixing rod 3 is rotated to fix the fixing rod 3 on the side of the wall; a connecting groove 31 is provided to connect the connecting rod 2 with the fixing rod 3, and the connecting rod 2 is extended into the connecting groove 31. The positioning block 4 enters the positioning groove under the action of elastic force, and a circular ring connecting block 5 is provided. The circular ring part on the circular ring connecting block 5 is threadedly connected to the fixing rod 3, changing its integrated structure, so that the observation mark can be easily replaced.

[0021] like Figure 2 As shown, in order to improve the reliability and stability of the connection between the connecting rod 2 and the fixing rod 3, two positioning blocks 4 are provided on the upper and lower sides of the connecting rod 2. The positioning blocks 4 on the upper and lower sides of the connecting rod 2 are symmetrically arranged, and the side surface of the positioning block 4 close to the connecting rod 2 is arranged to be an arc shape that matches the surface of the connecting rod 2, so that the positioning block 4 and the connecting rod 2 are more closely fitted to ensure the positioning effect.

[0022] like Figure 2 As shown, the inner wall of the connecting groove 31 is provided with a receiving groove 32, and a connecting plate is provided in the receiving groove 32. The two positioning blocks 4 are symmetrically fixedly arranged at the two ends of the connecting plate. The connecting plate is connected with an extension rod 6, and one end of the extension rod 6 passes through the outside of the fixed rod 3 and is fixedly connected with a stopper 7. A compression spring 8 is sleeved on the extension rod 6, and the compression spring 8 is arranged between the connecting plate and the bottom wall of the receiving groove 32. The elastic force of the compression spring 8 will cause the connecting plate to drive the two positioning blocks 4 to move toward the positioning groove on the connecting rod 2. The stopper 7 is provided to facilitate pulling the extension rod 6 through the stopper 7. When the connecting rod 2 is disassembled, the stopper 7 is pulled outward, so that the connecting plate drives the two positioning blocks 4 to move away from the corresponding positioning groove. The connecting plate is located in the receiving groove 32 and the compression spring 8 is compressed until the positioning block 4 completely escapes from the positioning groove.

[0023] Further, Figure 3 As shown, a reflective film 91 is provided on the outer surface of the rod body 1, and an anti-corrosion coating 92 is provided between the reflective film 91 and the rod body 1. The added reflective film 91 allows the device to be quickly found and observed at night, and the added anti-corrosion coating 92 prevents the surface of the device from being corroded, thereby effectively extending the service life of the device.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
