Description

Technical Field

[0001] This application relates to the field of equipment technology related to engineering cost, and more specifically, to a drawing measuring ruler for engineering cost estimation. Background Technology

[0002] A construction cost drawing measuring ruler is a tool used for measuring drawings in construction cost estimation, primarily to improve the efficiency of measurement on drawings. Specifically, this measuring ruler typically has an adjustable design, allowing its base length to be extended as needed to adapt to different measurement requirements.

[0003] In related technologies, an extension component is usually installed at the end of the measuring ruler so that the length of the measuring ruler can be increased by sliding the extension component, thereby achieving the function of rapid extension.

[0004] In practical use, drawing measurements require high accuracy. Furthermore, the extension component of the measuring ruler is typically slidably mounted inside the ruler. This means that during extended measurements, the extension component will come into contact with the drawing through the inner wall of the measuring ruler. In other words, there will be a certain gap between the extension component and the drawing, which prevents the scale lines of the measuring ruler from perfectly aligning with the drawing, resulting in measurement errors. Utility Model Content

[0005] In view of this, embodiments of this application provide a drawing measuring ruler for engineering cost estimation.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] A measuring ruler for engineering cost drawings, comprising:

[0008] The main ruler has scale lines on its surface. A first end face of the main ruler is recessed inward to form a storage groove. An opening communicating with the storage groove is provided on the first end face of the main ruler. The thickness of the first wall surface of the opening and the storage groove is greater than the thickness of its second wall surface. A groove is provided on the inner surface of the first wall surface along the thickness direction. The first wall surface is the wall surface of the main ruler that contacts the drawing, and the second wall surface is the side surface opposite to the first wall surface.

[0009] A secondary ruler, the surface of which is provided with the scale lines, is slidably disposed within the storage tank through the opening; a storage groove is provided on the end face of the secondary ruler, and a locking rod is rotatably disposed within the storage groove, the length of the locking rod being adapted to the length of the storage groove; wherein...

[0010] The auxiliary ruler is used to connect to the slot of the main ruler via the locking rod, so that the auxiliary ruler abuts against the drawing.

[0011] In some possible implementations, a semi-circular handle is fixedly provided at the second end of the main scale.

[0012] In some possible implementations, one end of the locking rod is provided with a T-shaped portion, and the inner surface of the first wall is provided with a corresponding T-shaped groove.

[0013] In some possible implementations, the locking lever and the slot are interference fits.

[0014] In some possible implementations, the length of the secondary ruler is greater than the depth of the storage tank.

[0015] In some possible implementations, the other end of the secondary ruler is provided with a notch.

[0016] The engineering cost drawing measuring ruler provided in this application embodiment has at least the following beneficial effects:

[0017] In the engineering cost drawing measuring ruler provided in this embodiment, the vernier scale is pulled outwards, and then the locking rod placed in the storage tank is rotated outwards so that the locking rod and the end face of the vernier scale are perpendicular. Then, the locking rod of the vernier scale is fastened into the groove on the inner wall of the main scale so that the lower surface of the vernier scale coincides with the lower surface of the main scale. Using this structural design, when the vernier scale and the main scale are installed together, the vernier scale can be directly fitted to the drawing, preventing a decrease in measurement accuracy caused by gaps between them.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-6 As shown in the embodiment of this application, the engineering cost drawing measuring ruler includes a main ruler 100 and a secondary ruler 400. Both the main ruler 100 and the secondary ruler 400 have scale lines 500 on their surfaces. The secondary ruler 400 serves as an extension component of the main ruler 100, extending its measuring range. A storage groove 120 is formed at the first end face of the main ruler 100 along its length, and an opening 110 communicating with the storage groove 120 is provided at the first end face of the main ruler 100. In actual use, the secondary ruler 400 can be slidably inserted into the storage groove 120 through the opening 110 to achieve a folding function, and can also be extended relative to the main ruler 100 according to actual needs.

[0029] The thickness of the first wall surface 200 at the opening 110 of the main scale 100 and the storage tank 120 is greater than the thickness of the second wall surface 300, such as Figure 2 As shown. The inner surface of the first wall surface 200 is recessed along its thickness direction to form a groove 210, which is located at the center point of the line connecting the width directions of the first wall surface 200. Furthermore, the opening 110 of the main ruler 100 and the first wall surface 200 of the storage tank 120 are surfaces that directly contact the drawing placed on the tabletop surface, and the second wall surface 300 is the opposite surface of the first wall surface 200.

[0030] In this embodiment, the auxiliary ruler 400 is slidably disposed within the storage tank 120 through the opening 110 on the first end face of the main ruler 100. A storage tank 410 is provided on the wall surface of the auxiliary ruler 400 in the width direction. A locking rod 600 is rotatably disposed within the storage tank 410, the length of which is adapted to the height of the storage tank 410. The locking rod 600 can rotate to a horizontal and a vertical position within the storage tank 410. When the locking rod 600 rotates to the vertical position, it is precisely located within the storage tank 410. When the locking rod 600 rotates to the horizontal position, the auxiliary ruler 400 can be engaged with the slot 210 of the main ruler 100 via the locking rod 600, allowing the outer surface of the first wall surface 200 of the auxiliary ruler 400 to directly contact the drawing. Preferably, the locking rod 600 and the slot 210 are interference fits.

[0031] In the engineering cost drawing measuring ruler provided in this embodiment, the auxiliary ruler 400 is pulled outwards, and then the locking rod 600 placed in the storage groove 410 is rotated outwards so that the end face of the locking rod 600 and the auxiliary ruler 400 are perpendicular. Then, the locking rod 600 of the auxiliary ruler 400 is fastened into the slot 210 on the inner wall of the main ruler 100 so that the lower surface of the auxiliary ruler 400 coincides with the lower surface of the main ruler 100. With the above structural design, when the auxiliary ruler 400 and the main ruler 100 are installed together, the auxiliary ruler 400 can be directly fitted with the drawing, preventing the decrease in measurement accuracy caused by gaps between the two.

[0032] In some embodiments, a semi-circular handle 700 is fixedly provided at the second end of the main ruler 100, which allows the cost estimator to easily hold and subsequently pick up the main ruler 100.

[0033] In some embodiments, such as Figure 5 As shown, the locking rod 600 has a T-shaped portion 800 at its end, and correspondingly, the main scale 100 has a T-shaped groove at its first wall surface 200 slot 210. The structure of the T-shaped portion 800 and the T-shaped groove increases the contact area between the main scale 100 and the secondary scale 400, thereby improving the connection stability between the two.

[0034] In some embodiments, such as Figure 6 As shown, the length of the auxiliary ruler 400 is greater than the depth of the inner storage tank 120 of the main ruler 100. Furthermore, the surface of the auxiliary ruler 400 located outside the inner storage tank 120 of the main ruler 100 is provided with a snap-fit ​​groove 900, which facilitates the cost estimator to pull out the auxiliary ruler 400 and its subsequent use.
