[0002] At present, embedded parts are components pre-installed or pre-buried in the engineering structure, used for the lap when building the upper structure, so as to facilitate the installation and fixation of the foundation of external engineering equipment. In order to accurately position the installation of external engineering equipment, it is necessary to accurately mark the position of the embedded parts when installing the embedded parts.

[0003] In the related art, first, the technician is familiar with the drawings and conducts a measurement technical disclosure. Then, the technician uses measurement tools to measure at the construction site, and then uses marking tools to paint and mark at the designated position.

[0004] In view of the above related art, the technician needs to spend time switching tools for marking after measurement, resulting in low marking efficiency. Moreover, during the process of tool switching, it is easy to shift and cause measurement errors, resulting in low marking accuracy. Therefore, there are problems of low positioning and marking efficiency and low accuracy.

[0005] In view of this, it is indeed necessary to provide a technical solution for a precise positioning and marking device for embedded parts to solve the above problems. Summary of the Utility Model

A limiting member is arranged on the side surface of the marking plate, and the limiting member is used to lock the sliding of the measuring rod relative to the marking plate.

[0009] As an optimization of a precise positioning and marking device for embedded parts, limiting cards are arranged at both end faces of the positioning holes. One end of the limiting card is rotatably arranged on the marking plate, and the other end of the limiting card abuts against the spraying mold.

[0010] As an optimization of a precise positioning and marking device for embedded parts, on the same end face of the positioning hole, at least 2 limiting cards are arranged, and the limiting cards are arranged at intervals along the circumference of the positioning hole.

[0022] The following Figures 1-3 is a further detailed description of the present application.

[0023] The present application provides a precise positioning marking device for embedded parts, adopting the following technical solutions:

[0024] Embodiment 1

[0025] Referring to Figure 1 , the precise positioning marking device for embedded parts includes a marking plate 1 and a measuring rod 2. The marking plate 1 is rectangular, and a positioning hole 3 is opened at the center point of the marking plate 1. The positioning hole 3 is a circular through hole that penetrates both sides of the marking plate 1. A spraying mold 4 is embedded in the positioning hole 3. The shape of the spraying mold 4 is the same as that of the positioning hole 3. The spraying mold 4 is hollowed out with marking patterns. Different spraying molds 4 correspond to different marking patterns. The marking patterns can be various graphics such as crosses and arrows. By spraying paint on the spraying mold 4, a standardized marking pattern can be generated at the construction site, replacing the manual painting operation of technicians, which helps construction workers to identify and construct. There are 2 measuring rods 2. The two measuring rods 2 are respectively located on both sides of the marking plate 1. One end of the measuring rod 2 slidably penetrates through one side of the marking plate 1. A push rod 7 is perpendicularly welded to the side surface of the other end of the measuring rod 2. The push rod 7 facilitates the technician to drive the measuring rod 2 to move relative to the marking plate 1. The two ends of the push rod 7 are respectively welded to the ends of the measuring rods 2 on both sides of the marking plate 1. Scale marks 21 are drawn on the measuring rod 2. The scale marks 21 are used to display the position of the push rod 7 to the center of the positioning hole 3. A limiting member 5 is installed on the side surface of the marking plate 1. The limiting member 5 is used to lock the sliding of the measuring rod 2 relative to the marking plate 1, so as to fix the distance between the push rod 7 and the positioning hole 3, which is convenient for spraying the spraying mold 4 and improves the accuracy of positioning marking.

[0026] Further, referring to Figure 2 , the limiting member 5 includes a limiting block 51. A sliding hole of the same size as the limiting block 51 is formed on the side surface of the marking plate 1, and the limiting block 51 is slidably embedded in the sliding hole. When the limiting block 51 is pressed into the sliding hole, the limiting block 51 abuts against the side surface of the measuring rod 2, restricting the movement of the measuring rod 2, thereby locking the sliding of the measuring rod 2 relative to the marking plate 1, facilitating spraying, and being beneficial to improving the accuracy of the positioning mark. When the limiting block 51 is pulled out of the sliding hole, the side surface of the limiting block 51 away from the measuring rod 2, and the measuring rod 2 slides freely to change the distance, thus facilitating the next measurement, being beneficial to repeated use, and improving the positioning mark efficiency.

[0027] In a preferred embodiment of the present application, referring to Figure 1 , limiting cards 6 are installed at both end faces of the positioning hole 3. One end of the limiting card 6 is rotatably installed on one side of the marking plate 1, and the other end of the limiting card 6 is a free end. When the spraying die 4 is embedded in the positioning hole 3, the free end of the limiting card 6 is rotated to the end face of one end of the positioning hole 3, and the limiting card 6 abuts against the spraying die 4. Through the limiting cards 6 at both end faces of the positioning hole 3, the spraying die 4 can be restricted from sliding out of the positioning hole 3; when the spraying die 4 needs to be taken out, the free end of the limiting card 6 is rotated from the end face of the positioning hole 3 to the marking plate 1, and the spraying die 4 is taken out of the positioning hole 3, thereby detachably limiting and installing the spraying die 4 in the positioning hole 3, facilitating the technician to replace different marking styles, and further meeting different positioning mark requirements. In this embodiment, the limiting card 6 is triangular, and the limiting cards 6 on both end faces are located in the same orientation of the positioning hole 3. In other embodiments, the limiting card 6 can be in the shape of a rectangle, a rhombus, etc., or the limiting cards 6 on both end faces are located in different orientations of the positioning hole 3 and other ways to limit the spraying die 4 in the positioning hole 3, which all belong to the flexible settings of this embodiment.

[0028] Even further, referring to Figure 1 , on the same end face of the positioning hole 3, at least 2 limiting cards 6 are installed, and the multiple limiting cards 6 are installed at intervals along the circumference of the positioning hole 3. In this embodiment, on the same surface, 4 limiting cards 6 are installed, and the 4 limiting cards 6 are distributed at the four equal division points of the circumference of the positioning hole 3, restricting the spraying die 4 from sliding out of the positioning hole 3, thereby improving the reliability of the installation of the spraying die 4.

[0029] Embodiment 2

[0030] Different from Embodiment 1, referring to Figure 3, the limiting member 5 includes an abutting bolt 52. The abutting bolt 52 is inserted through the side surface of the marking plate 1, and the abutting bolt 52 is threadedly connected to the side surface of the marking plate 1. When the abutting bolt 52 is screwed into the marking plate 1, the abutting bolt 52 abuts against the side surface of the measuring rod 2, restricting the movement of the measuring rod 2, thereby locking the sliding of the measuring rod 2 relative to the marking plate 1 and being able to self-lock in the measuring position, fixing the spraying position, which is beneficial to improving the accuracy of the positioning mark.

[0031] Experimental principle of the embodiment of the present application: When it is necessary to position and mark the embedded part, align the measuring rod 2 with the measuring position, slide the marking plate 1 along the measuring rod 2 until the positioning hole 3 moves to the positioning position, press the limiting member 5 to lock the distance between the measuring rod 2 and the marking plate 1, and then limit and install the spraying mold 4 with the corresponding marking style in the positioning hole 3 through the limiting card 6, which is convenient for spraying and marking. When performing multiple equidistant positioning marks, after the first positioning, directly translate the device to the next marking position for positioning, which can perform continuous marking, reduce the repeated measurement time, and thus improve the positioning mark efficiency and accuracy. When variable-distance marking is required, unlock the limiting member 5 to enable the measuring rod 2 to freely slide on the marking plate 1, thereby quickly performing the next measurement and improving the positioning mark efficiency. In addition, through the device, the functions of the measuring tool and the marking tool can be realized simultaneously, which not only reduces the measurement error of displacement, improves the positioning accuracy, but also reduces the cost, is convenient for carrying and handling, repeated use and continuous marking, and is beneficial to improving the positioning mark efficiency.

[0032] According to the disclosure and teaching of the above specification, those skilled in the art of the present invention can also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the above specific embodiments, and any obvious improvements, substitutions or variations made by those skilled in the art on the basis of the present invention all belong to the protection scope of the present invention. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present invention.
