DETAILED DESCRIPTION

[0021] The technical scheme of the patent will be further explained in detail below in combination with the specific embodiments.

[0022] Please refer to Figures 1-5A leveling rod for engineering surveying includes a leveling rod body 1. Insertion sleeves 2 are fixedly connected to both sides of the leveling rod body 1 near the bottom. Insertion connectors 3 are movably inserted into the insertion sleeves 2. Locking components 4 are provided on the insertion connectors 3. When only the leveling rod body 1 needs to be used and does not need to be fixed to the ground, the locking components 4 can be used to release the restriction on the insertion connectors 3, and then the insertion connectors 3 can be removed from the insertion sleeves 2, thereby removing the mounting plate 6. This makes the leveling rod body 1 simple in structure and easy to use. The plug sleeve 2 has limiting holes 5 on both sides for use with locking components 4. Mounting plates 6 are fixedly connected to the two plugs 3 on the side away from each other. Storage grooves 7 are provided on both sides of the mounting plates 6. A flip block 8 is rotatably connected in the storage groove 7 via a rotating shaft. A conical foot nail 9 is connected to the bottom of the flip block 8. A fixing bolt 10 is passed through the flip block 8. A first through hole 11 and a second through hole 12 are provided on the mounting plate 6 at an interval between the top and bottom. When the fixing bolt 10 is inserted into the first through hole 11, the conical foot nail 9 will be inside the storage groove 7. When the fixing bolt 10 is inserted into the second through hole 12, the conical foot nail 9 will be outside the storage groove 7. When the tower gauge is not in use, remove the fixing bolt 10 from the first through hole 11, and then rotate the flip block 8 upward. At this time, the conical foot nail 9 will be retracted into the storage groove 7. Then, insert the fixing bolt 10 through the flip block 8 and the first through hole 11 to fix the flip block 8. The retraction of the conical foot nail 9 into the storage groove 7 can effectively prevent personnel from accidentally touching the conical foot nail 9 and getting injured.

[0023] Furthermore, the main body 1 of the measuring rod is a conventional telescopic aluminum alloy measuring rod.

[0024] Furthermore, the locking assembly 4 includes two sliding grooves 401 formed inside the connector 3 and corresponding to the two limiting holes 5 respectively. A through groove 402 connected to the sliding grooves 401 is formed on the top of the connector 3. A limiting rod 403 adapted to the limiting hole 5 is slidably arranged in the sliding groove 401. A lever 404 is fixedly connected to the end of each limiting rod 403 that is close to each other. A spring 405 is provided on the innermost side of the sliding groove 401. When it is necessary to remove the connector 3 from the connector sleeve 2, it is done by...

[0025] Furthermore, the bottom of the mounting plate 6 is provided with a weight-reducing groove 13 located between two storage grooves 7 in the vertical direction, which can reduce the weight of the mounting plate 6 and make it easier for staff to transport and carry the measuring rod.

[0026] Furthermore, the bottom of the flip block 8 is provided with a threaded groove 14, and a screw 15 adapted to the threaded groove 14 is integrally formed on the top of the conical foot nail 9. The conical foot nail 9 is detachably connected to the flip block 8 through the cooperation of the threaded groove 14 and the screw 15. The detachable design of the conical foot nail 9 makes it easy to replace it when it is severely worn.

[0027] When using, when only the tower ruler body 1 needs to be used, without being fixed on the ground, two limit rods 403 can be driven to move to the opposite direction by relatively pressing two pressing pieces 404 (at this time, two springs 405 are compressed), so that the ends of the two limit rods 403 far away from each other are simultaneously separated from the limiting holes 5, so as to release the limiting of the plug-in connector 3, then the plug-in connector 3 can be taken out from the plug-in sleeve 2, so as to dismount the mounting plate 6, so that the tower ruler body 1 is simple in structure and convenient to use, when the tower ruler is not used, the fixing bolt 10 is dismounted from the first through hole 11, then the turnover block 8 is turned upward, at this time, the conical foot nail 9 is retracted into the storage groove 7, then the fixing bolt 10 is arranged in the turnover block 8 and the first through hole 11, the turnover block 8 is fixed, the conical foot nail 9 retracted into the storage groove 7 can effectively prevent people from being injured by accidentally touching the conical foot nail 9.

[0028] The above-mentioned embodiments are the preferred embodiments of the present application, which are only used to facilitate the description of the present application and do not limit the present application in any form, any person with ordinary knowledge in the art can make equivalent embodiments by making partial changes or modifications within the range of the technical features of the present application without departing from the technical features of the present application, and the equivalent embodiments still belong to the range of the technical features of the present application.
