Description

Technical Field

[0001] The utility model relates to the technical field of measuring devices, in particular to a measuring device used in construction engineering technology. Background Art

[0002] A construction project refers to an engineering entity formed through the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. Among them, "buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that can meet people's needs for production, residence, study, and public activities.

[0003] The Chinese utility model with the authorization announcement number CN221140659U discloses a measuring line winding device for construction engineering measurement. When the device is in use, the measuring line and the storage box are sealed by the box cover and the sealing cover respectively. The winding box and the ink storage box of most existing ink cartridge winding measuring lines are both in an open state. The use scene of the ink cartridge is dusty. After the ink cartridge is used for a long time, a lot of dust will enter the winding box and the storage box, affecting the smoothness of the use of the measuring line. However, there are certain defects in actual use. The ink cartridge of the device does not have a guide mechanism inside. When the measuring line is wound, the measuring line will curl, knot or entangle together. This situation not only increases the difficulty of winding, but also may cause damage to the measuring line, affecting the measurement accuracy and efficiency. Therefore, it is necessary to redesign a measuring device for construction engineering technology to address the above problems. Utility Model Content

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Refer to Figures 1-3 , a measuring device for construction engineering technology, including an ink cartridge 1. The upper end of the ink cartridge 1 is open. A reciprocating lead screw 12 and a rewinding roller 3 are rotatably connected to the inner wall of the ink cartridge 1. A measuring line 10 is wound around the outer wall of the rewinding roller 3. One end of the measuring line 10 passes through the body of the ink cartridge 1 and is connected with a limiting cone 9. The reciprocating lead screw 12 is connected with a guide cylinder 11 through a connecting mechanism. Both ends of the guide cylinder 11 are open. The measuring line 10 is slidably connected inside the guide cylinder 11;

[0022] The design of the guide cylinder 11 ensures that the measuring line 10 remains in a straight state during the rewinding process, avoiding problems such as curling, knotting and entanglement, and improving the service life and measuring accuracy of the measuring line 10.

[0023] The connecting mechanism includes a lead screw sleeve 14 threadedly connected to the threaded section of the reciprocating lead screw 12. The guide cylinder 11 is fixedly connected to the upper end face of the lead screw sleeve 14;

[0024] By driving the guide cylinder 11 to slide with the help of the lead screw sleeve 14, the measuring line 10 can be evenly wound around the outer wall of the rewinding roller 3.

[0025] A limiting rod 13 is fixedly connected to the inner wall of the ink cartridge 1. The lead screw sleeve 14 is slidably connected to the outer wall of the limiting rod 13. A first driving wheel 4 and a second driving wheel 5 are rotatably connected to the outer wall of the ink cartridge 1. The radius of the first driving wheel 4 is larger than the radius of the second driving wheel 5. The first driving wheel 4 is connected to the second driving wheel 5 through a transmission belt 6. The first driving wheel 4 is coaxially and fixedly connected to the rewinding roller 3. The second driving wheel 5 is coaxially and fixedly connected to the reciprocating lead screw 12. A sealing cover plate 2 is rotatably connected to the outer wall of the ink cartridge 1. A handle 8 is fixedly connected to the side wall of the ink cartridge 1. A rotary handle 7 is coaxially and fixedly connected to the outer wall of the first driving wheel 4.

[0026] In the present utility model, the specific functions of the device are as follows: Open the sealing cover plate 2 to ensure that the inside and outside of the ink cartridge 1 are clean and dust-free. Drag the limit cone 9 to conduct measurement. After the measurement is completed, rotate the turning handle 7 to drive the first transmission wheel 4 to rotate. The first transmission wheel 4 transmits power to the second transmission wheel 5 through the transmission belt 6. The rotation of the second transmission wheel 5 drives the reciprocating lead screw 12 to rotate. The winding roller 3 and the reciprocating lead screw 12 move synchronously. The rotation of the reciprocating lead screw 12 causes the lead screw sleeve 14 to slide on the limit rod 13, thereby driving the guide cylinder 11 to reciprocate inside the ink cartridge 1. The reciprocating movement of the guide cylinder 11 ensures that the measurement line 10 is evenly wound on the outer wall of the winding roller 3, avoiding curling, knotting or entanglement of the measurement line 10.

[0027] After use, close the sealing cover plate 2 to prevent dust from entering the inside of the ink cartridge 1 and protect the measurement line 10 and the internal structure.

[0028] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
