Description

Technical Field

[0001] The utility model relates to the technical field of observation rods, in particular to an observation rod for building detection. Background Art

[0002] The observation pole for building inspection is a tool that plays an important role in the field of building inspection. The observation pole is installed in a specific position and is generally closely integrated with the building through pre-embedding and other methods. Its working principle is mainly to regularly observe the specific marks or measuring points on the observation pole to determine the vertical displacement changes of the building. The observer uses professional measuring instruments, such as levels, total stations, etc., to accurately measure the height or position changes of the observation pole.

[0003] Existing technologies include a utility model with publication number CN208751539U. The utility model discloses an observation rod for building inspection, including a rod body, the end of the rod body has an anti-slip portion to prevent it from rotating on the building, and the other end of the rod body is provided with a reference rod perpendicular to the rod body. The advantages are: the utility model has better tightness, which can make observation more accurate, and solves the problem that the existing observation rod is prone to rotation after a period of time due to poor tightness, which will affect the observation results.

[0004] In daily work, it is found that the existing observation rods used for building inspections have a single and fixed structure. The observation rods are embedded or installed in the building walls. However, after embedding or installation, the heads of the observation rods will extend outside the wall. In this way, the heads of the observation rods are easily bumped, causing damage to the observation rods. Once the observation rods are damaged, subsequent building inspections will be affected, reducing the accuracy and reliability of the inspections. This leads to the problem that the existing observation rods extending outside the wall are easily bumped and affected in terms of inspection accuracy. Utility Model Content

The shielding component 34 includes a cover body 341, the cover body 341 is located at one end of the embedded sleeve 31, and one end of the cover body 341 is fixedly connected to a handle 342. The surface of the cover body 341 is fixedly connected with a threaded end 345, and a threaded groove 346 is provided on the surface of the embedded sleeve 31.

A limiting component 36 is provided between the rotating shaft 38 and the rod body 1, and a ejection component 35 is provided on the inner wall of the embedded sleeve 31.

[0026] In this embodiment: the embedded sleeve 31 can be embedded in the building. When settlement detection is required, the cover body 341 can be rotated to remove the threaded end 345 from the threaded groove 346, and then the rod body 1 can be slid in the embedded sleeve 31. The rod body 1 can drive the cap body 2 to be pulled out of the embedded sleeve 31, and then the cap body 2 is rotated to make the cap body 2 perpendicular to the rod body 1, and the detection can be carried out. When it is not needed, the cap body 2 can be rotated to make the cap body 2 level with the rod body 1, and the cap body 2 and the rod body 1 are pushed into the embedded sleeve 31 to hide them, and then the embedded sleeve 31 is sealed by the cover body 341.

[0027] Specifically, the shielding assembly 34 further includes a ring 343 , which is rotatably connected to the surface of the cover body 341 , and an elastic rope 344 is fixedly connected to the surface of the ring 343 , and the other end of the elastic rope 344 is fixedly connected to the surface of the embedded sleeve 31 .

[0028] In this embodiment, the elastic rope 344 cooperates with the ring 343 to store the cover 341, thereby reducing the inconvenience of placing the cover 341 after it is removed.

[0029] Specifically, the ejection assembly 35 includes a top plate 351, which is slidably connected to the inner wall of the embedded sleeve 31. A spring 352 is fixedly connected to the side of the top plate 351 corresponding to the inner wall of the embedded sleeve 31. The spring 352 cooperates with the top plate 351 to push the rod body 1 and the cap body 2 out a certain distance, thereby facilitating manual extraction.

[0030] Specifically, the limiting assembly 36 includes a limiting member 361, which is slidably connected to the inner wall of the rod body 1. A rack 362 is fixedly connected to the surface of one side of the limiting member 361, and a gear 363 is fixedly connected to the surface of the rotating shaft 38. The gear 363 is meshed with the rack 362.

[0034] In this embodiment, the second spring 39 can automatically drive the cap body 2 to rotate and reset, thereby improving the overall usability.

[0035] Specifically, a marking line 32 is fixedly connected to the surface of the embedded sleeve 31, and the marking line 32 facilitates positioning during embedding, thereby improving the embedding accuracy.

[0036] Working principle: The embedded sleeve 31 can be embedded in the building. When settlement detection is required, the cover body 341 can be rotated to remove the threaded end 345 from the threaded groove 346. After the cover body 341 is removed, the pull rope cooperates with the ring 343 to store the cover body 341. Then the spring 1 352 releases the elastic force to push the top plate 351 to move. The top plate 351 can push the rod body 1 out of the embedded sleeve 31 for a certain distance, and then pull the cap body 2. When the rod body 1 is against the positioning ring 37, the spring 2 39 releases the elastic force, driving the rotating shaft 38 and the cap body 2 to rotate. At the same time, the rotating shaft 38 drives the gear 363 to rotate, and the gear 363 cooperates with the rack 362. The limiting member 361 is driven to be inserted into the positioning hole 365 on the surface of the embedded sleeve 31, so that it can be tested. When it is not needed, the cap body 2 can be rotated to make the cap body 2 and the rod body 1 level. At this time, the spring 2 39 is stressed, and the gear 363 drives the rack 362 and the limiting member 361 to reset. The limiting member 361 is pulled out from the positioning hole 365, and then the cap body 2 and the rod body 1 are pushed into the embedded sleeve 31. The rod body 1 squeezes the top plate 351, and the spring 1 352 is stressed to achieve hiding. Then the threaded end 345 on the cover body 341 is connected to the threaded groove 346 in the embedded sleeve 31 to achieve blocking of the embedded sleeve 31 and complete use.
