Description

Measurement target plate of anti-blocking screw thread Technical Field The utility model relates to the technical field of measurement targets, in particular to an anti-blocking threaded measurement target. Background The measuring target is also called a central target, and the central target is two pieces of profile steel with a certain length which are buried on the central line of the basic surface at two ends of the equipment when the foundation is irrigated, and a central line point is marked on the profile steel and is used as a target point for aligning the position of the equipment when the equipment is installed and paid off. The prior measuring target is easy to block the target screw thread after being embedded so as to influence the cover opening of the target, and in order not to influence the cover opening in the embedding process, the target screw thread is higher than the ground in the embedding process, but the higher part is easy to bump so as to influence the precision of the target, or the target screw thread is embedded flush with the ground, and in order to prevent the target screw thread from being influenced by grouting materials or epoxy resin in a construction site, the screw thread is chiseled after secondary casting or casting is finished, but the quality and the engineering progress of the target are influenced. Therefore, there is a need for a measurement target that is resistant to clogging-up threads. Disclosure of utility model Aiming at the problems in the prior art, the utility model aims to provide the measuring target with anti-blocking screw threads, and solve the problem that grouting materials are easy to block the screw threads of the target after the existing measuring target is buried so as to influence the cover opening of the target. The utility model adopts the following technical scheme: A measurement target for anti-blocking threads, comprising: A center target; The anti-blocking protection groove box is arranged at the upper end of the central target, and the screw thread part of the central target is arranged in the anti-blocking protection groove box; The embedded reinforcing part is arranged at the lower end of the center target. Further, the center target comprises a target main body and a screw thread part fixedly arranged at the upper end of the target main body, and an end cover is arranged on the screw thread part. Further, the external diameter of the screw thread part is larger than the diameter of the target main body, the screw thread part is provided with external threads, and the screw thread part is in threaded connection with the end cover. Further, the top of the end cover is flush with the top of the anti-blocking protection groove box. Further, the lower extreme of target main part is equipped with the external screw thread, installs the die-pin on the target main part, and the die-pin is located the lower extreme of anti-blocking protection groove box, die-pin and target main part threaded connection. Further, the upper end of the embedded reinforcing part is provided with a connecting ring, and the connecting ring is in threaded connection with the target main body. Further, the embedded reinforcing part further comprises a first slat and 2 second slats, the 2 second slats are arranged on two sides of the first slat, the first slat is perpendicular to the second slat, and the first slat and the second slat are both fixed at the bottom of the connecting ring. Advantageous effects 1. Through setting up the upper end at the center target with preventing stifled protection groove box, and the screw thread portion setting of center target is in preventing stifled protection groove box for this measurement target is when burying underground, prevents stifled protection groove box can prevent that the grout material from plugging up the target screw thread, thereby can not influence the target and uncap. 2. The buried height behind the center target lid upper end cover is parallel and level with ground, and prevent stifled protection groove box's the top and the top parallel and level of center target for this measurement target is buried underground the back, and the upper end can not be higher than ground, thereby can not appear traditional measurement target that buries the mode and lead to take place to bump easily to influence the phenomenon of target precision above ground part, thereby prevent stifled protection groove box can prevent that the grout material from plugging up the target screw thread simultaneously, also need not pour or pour the back chisel screw thread of accomplishing. 3. The embedded reinforcing part is arranged at the lower end of the central target, so that the embedded firmness can be improved by fully contacting the embedded reinforcing part with grouting materials when the embedded reinforcing part is embedded.
