When inspecting the building structure, various measuring rulers are generally used to measure various specifications, lengths, widths, and other data of the building. This facilitates the creation of corresponding drawings based on the building's structure and assists in safe construction. The measuring rulers are divided into tape measures, rulers, and spirit levels, depending on the usage scenario and needs. Among them, the hand-cranked ground tape measure is the most commonly used when inspecting large-scale and long-distance building projects.

[0003] When using a hand-cranked ground-inserting measuring tape, the end of the tape is fixed at the target position, and then the handle is cranked to adjust the length of the output tape until the tape length matches the distance to be measured.

DETAILED DESCRIPTION

[0023] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model will be described in detail below with reference to the drawings of the specification.

[0024] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be practiced in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited by the specific embodiments disclosed below.

[0025] Secondly, "one embodiment" or "embodiment" referred to herein means that a specific feature, structure or characteristic can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in this specification does not mean the same embodiment, nor is it an embodiment that is independent of or mutually exclusive of other embodiments. The present application provides the following embodiments.

[0026] As shown by Figure 1 and Figure 2 , it is a structure schematic view of the measuring ruler in the embodiment, which comprises an outer frame 1, a winding ruler main body 2, a rocking handle 3 and a ground insertion cone 4, the outer frame 1 is internally provided with the winding ruler main body 2 for detecting distance, the outer frame 1 is provided on the side with the rocking handle 3 for adjusting the length of the output winding ruler main body 2, and the outer frame 1 is provided at the bottom end with the ground insertion cone 4, and the ground insertion cone 4 is internally provided with the output mechanism 5 for adjusting the output position of the winding ruler main body 2.

[0027] In use, the end of the retractable measuring tape body 2 is attached to the target area and fixed. Then, the handle 3 is cranked, so that the retractable measuring tape body 2, which is wound inside the outer frame 1, is gradually released according to the number of cranking turns of the handle 3. The overall output length of the retractable measuring tape body 2 is adjusted. Then, the distance between the current position and the end of the retractable measuring tape body 2 is determined according to the scale display on the surface of the retractable measuring tape body 2, thus completing the detection of the overall structure of the project.

[0028] From the appendix Figure 3 As shown, this is a schematic diagram of the output mechanism 5 in this embodiment. The output mechanism 5 includes a conveying roller 51, a mounting frame 52, and an output roller 53. The conveying roller 51 is rotatably installed inside the outer frame 1. The retractable measuring tape body 2 rolls along the outside of the conveying roller 51. An output groove is opened in the grounding cone 4 to cooperate with the output of the retractable measuring tape body 2. The mounting frame 52 is symmetrically installed on one side of the grounding cone 4. The output roller 53 is rotatably installed between the mounting frames 52. The retractable measuring tape body 2 passes through the output groove and fits against the outside of the output roller 53.

[0029] During use, the main body 2 of the retractable measuring tape extends along the output groove. At this time, the length and angle of the output of the main body 2 of the retractable measuring tape are limited by the cooperation of the conveying roller 51 and the output roller 53, so as to prevent the main body 2 of the retractable measuring tape from rubbing against the inner wall of the ground cone 4, which would affect the normal service life of the main body 2 of the retractable measuring tape. In addition, by cooperating with the mounting bracket 52 and the output roller 53, the output port of the main body 2 of the retractable measuring tape is brought as close as possible to the bottom end of the ground cone 4, reducing the distance between the main body 2 of the retractable measuring tape and the ground, which facilitates the accurate detection of the current engineering distance and improves the overall working quality of the equipment.

[0030] From the appendix Figure 4 As shown, this is a structural schematic diagram of the positioning mechanism 6 in this embodiment. The measuring ruler also includes the positioning mechanism 6. The positioning mechanism 6 includes a fixed end 61, a support frame 62, a rotating rod 63, a limiting block 64, and a snap-fit ​​component 65. The fixed end 61 is installed at the end of the retractable measuring ruler body 2. The support frame 62 is symmetrically installed on the side of the fixed end 61. The rotating rod 63 is rotatably installed between the support frames 62. The limiting block 64 is installed on the outer wall of the rotating rod 63. The snap-fit ​​component 65 is installed on one of the support frames 62.

[0031] In use, by attaching the limiting block 64 to the target area, the angle between the rotating rod 63 and the limiting block 64 is used to fix and position the end of the retractable measuring tape body 2, which facilitates the subsequent stretching of the retractable measuring tape body 2 and ensures the detection accuracy of the retractable measuring tape body 2. However, when the end of the retractable measuring tape body 2 is attached to the corner of the wall, the conventional limiting block 64 will prevent the end of the retractable measuring tape body 2 from attaching to the ground. At this time, by using the snap-fit ​​part 65, the angle of the limiting block 64 is adjusted to help the end of the retractable measuring tape body 2 to attach stably to the ground at the corner of the wall, thereby improving the overall working quality of the equipment.

[0032] From the appendix Figure 5 As shown, this is a schematic diagram of the snap-fit ​​component 65 in this embodiment. The snap-fit ​​component 65 includes a housing 651, a snap-fit ​​rod 652, a spring assembly 653, and a pull rod 654. The housing 651 is mounted on one of the support frames 62. The snap-fit ​​rod 652 is slidably mounted inside the housing 651. The output end of the snap-fit ​​rod 652 passes through the support frame 62 and the side wall of the housing 651. The pull rod 654 is mounted on the end of the snap-fit ​​rod 652 and is slidably connected to the housing 651. The spring assembly 653 is sleeved on the outside of the pull rod 654. The side wall of the rotating rod 63 is symmetrically provided with snap-fit ​​grooves on the side near the snap-fit ​​rod 652. The spring assembly 653 is slidably inserted into the snap-fit ​​grooves. The overall thickness of the fixed end 61 is greater than the width of the output groove.

[0033] In use, the pull rod 654 is pulled first. Under the pull of the pull rod 654, the locking rod 652 retracts into the outer shell 651. At this time, the engagement between the locking rod 652 and the locking groove is released. Then, the limit block 64 is moved, so that the rotating rod 63 rotates between the support frame 62, adjusting the overall angle of the limit block 64 until the limit block 64 flips to the other side. By releasing the pull rod 654, under the action of the spring group 653, the locking rod 652 will pop out to the side and enter another set of locking grooves, thereby locking the angle and position of the limit block 64.

[0034] From the appendix Figure 6 As shown, the ground-inserting cone 4 is equipped with locking blocks on both sides, and a protective shell 7 is provided at the bottom of the ground-inserting cone 4. The protective shell 7 is sleeved on the outside of the ground-inserting cone 4 through the locking blocks. When the measuring ruler is not in use, the protective shell 7 is sleeved on the outside of the ground-inserting cone 4 to cover and store the sharp part of the ground-inserting cone 4 and the top of the retractable measuring ruler body 2, preventing the measuring ruler from colliding with the staff during the movement and improving the overall safety of the equipment.

[0035] The above description provides a more detailed explanation of the present invention in conjunction with specific embodiments. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention.
