Description

Technical Field

[0001] This utility model relates to a measuring ruler, specifically an engineering measuring ruler. Background Technology

[0002] In the engineering field, measuring rulers, especially those used for height measurement in design, play a crucial role. These tools can accurately measure the height of objects, providing precise data support for construction.

[0003] The leveling rod is mainly used for elevation measurement in engineering surveying, such as ground elevation and building height. Its high precision and portability make it an important tool in engineering surveying. The leveling rod consists of multiple sections. Since the leveling rod is existing technology, it will not be discussed in detail here.

[0004] However, in some cases, when the leveling rod is used to measure the height of an object, there are obstructions around the object. Because of these obstructions, the leveling rod cannot directly contact the object. In this case, the leveling rod can only be tilted to measure the height of the object, which will result in the measurement result being too high or too low, resulting in inaccurate measurement. Summary of the Invention

[0005] Therefore, this utility model provides an engineering measuring ruler that solves the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides an engineering measuring ruler, including a measuring ruler body and an extension component;

[0007] The extension assembly has two sets, which are respectively arranged on both sides of the top of the tower gauge body. Each set of extension assemblies includes two connecting plates, a fixed shaft, and a rotating plate. The two connecting plates are respectively arranged on the top side of the tower gauge body. The fixed shaft is arranged between the two connecting plates. The inner end of the rotating plate is sleeved on the fixed shaft through an elliptical hole.

[0008] The aforementioned beneficial effect is that when there are obstructions around the object, the operator rotates the rotating plate. The inner end of the rotating plate rotates from vertical to horizontal on the fixed shaft through the elliptical hole. After the rotating plate reaches the horizontal position, it is pressed down so that the upper end of the elliptical hole contacts the fixed shaft, thus fixing the rotating plate in a horizontal position. Then, the leveling rod body can be placed in a suitable position so that the rotating plate contacts the highest point of the object. At this time, the leveling rod body remains vertical, and the measurement value on the leveling rod can be read, which is the height of the object. After the measurement is completed, the rotating plate is moved up, and the lower end of the elliptical hole contacts the fixed shaft, allowing the rotating plate to be rotated from horizontal to vertical. The rotating plate is then folded up. In this way, even when there are obstructions around the object, the measurement results can still remain accurate and without error.

[0009] A preferred embodiment is that the lower inner end of the rotating plate is provided with an arc shape.

[0010] A preferred embodiment further includes an extension plate, one end of which is provided with a protrusion, the outer end of which is provided with an insertion groove, and insertion holes are provided on both sides of the insertion groove. A connecting hole is provided on the protrusion, and the connecting hole mates with the insertion hole.

[0011] A preferred embodiment is that a support plate is provided at the lower end of the tower gauge body, and insert rods are respectively provided at the four corners of the lower end of the support plate.

[0012] A preferred embodiment is that the tower gauge body and the support plate are detachably connected. The lower end of the tower gauge body is provided with threaded holes on both sides. The support plate is provided with two vertical plates, each with a circular hole that engages with the threaded hole. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] like Figures 1 to 5 As shown, this utility model provides an engineering measuring ruler, including a measuring ruler body 10 and an extension component 20;

[0022] The extension component 20 has two sets, and the two sets of extension components 20 are respectively arranged on both sides of the top end of the tower gauge body 10. Each set of extension components 20 includes two connecting plates 21, a fixed shaft 22, and a rotating plate 23. The two connecting plates 21 are respectively arranged on the top side of the tower gauge body 10. The fixed shaft 22 is arranged between the two connecting plates 21. The inner end of the rotating plate 23 is sleeved on the fixed shaft 22 through an elliptical hole 24.

[0023] During the measurement process, when there are obstructions around the object, the operator rotates the rotating plate 23. The inner end of the rotating plate 23 rotates from vertical to horizontal on the fixed shaft 22 through the elliptical hole 24. After the rotating plate 23 is horizontal, it is pressed down so that the upper end of the elliptical hole 24 contacts the fixed shaft 22, thus fixing the rotating plate 23 in a horizontal position. Then, the leveling rod body 10 can be placed in a suitable position so that the rotating plate 23 contacts the highest point of the object. At this time, the leveling rod body 10 remains vertical, and the measurement value on the leveling rod can be read, which is the height of the object. After the measurement is completed, the rotating plate 23 is moved up, and the lower end of the elliptical hole 24 contacts the fixed shaft 22, allowing the rotating plate 23 to be rotated from horizontal to vertical. The rotating plate 23 is then folded up. In this way, even when there are obstructions around the object, the measurement result can still remain accurate without error.

[0024] Preferably, an arc shape 25 is provided on the lower inner end of the rotating plate 23.

[0025] When the rotating plate 23 rotates from horizontal to vertical, that is, when it is folded up, the person moves the rotating plate 23 upward. At this time, the lower end of the elliptical hole 24 contacts the fixed shaft 22. Then, through the action of the arc 25, the rotating plate 23 can rotate from horizontal to vertical.

[0026] Preferably, the plate also includes an extension plate 31, one end of which is provided with a protrusion 32, the outer end of the rotating plate 23 is provided with an insertion groove 33, and the two sides of the insertion groove 33 are respectively provided with insertion holes 34. The protrusion 32 is provided with a connecting hole 35, and the connecting hole 35 cooperates with the insertion hole 34.

[0027] When the obstruction is large and the rotating plate 23 cannot contact the highest position of the object, the protrusion 32 of the extension plate 31 can be inserted into the insertion slot 33 in advance. Then, bolts are inserted into the insertion hole 34 and the connecting hole 35, and nuts are screwed on the bolts. This increases the length of the rotating plate 23 and solves the problem of not being able to measure when the obstruction is large.

[0028] Preferably, a support plate 41 is provided at the lower end of the tower gauge body 10, and a rod 42 is provided at each of the four corners of the lower end of the support plate 41.

[0029] During measurement, personnel can insert the rod 42 below the ground, which will make the measuring rod body 10 more stable during measurement.

[0030] Preferably, the tower gauge body 10 is detachably connected to the support plate 41. Threaded holes 51 are provided on both sides of the lower end of the tower gauge body 10. Two vertical plates 52 are provided on the support plate 41. Circular holes 53 are provided on each of the two vertical plates 52, and the circular holes 53 cooperate with the threaded holes 51.

[0031] When it is necessary to separate the support plate 41 from the tower gauge body 10, the operator rotates the two threaded rods, causing them to move out of the two threaded holes 51 respectively. Then the tower gauge body 10 can be removed from the two vertical plates 52 to complete the separation. When connecting, the lower end of the tower gauge body 10 is placed between the two vertical plates 52, and then the threaded rod is screwed into the threaded hole 51 through the circular hole 53 to complete the connection. It can be used as needed.

[0032] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
