Description

Technical Field

[0001] This utility model relates to a measuring instrument, and more particularly to a measuring tape. Background Technology

[0002] Measuring tapes are a commonly used tool in construction cost estimation. To more accurately control construction costs, engineers need to conduct precise measurements on the construction site. Currently, engineers typically use one hand to hold the measuring tape and the other hand to mark lines, which is inconvenient. While some measuring tapes on the market come with built-in markers, allowing for one-handed measurement and marking, these are difficult to use on dusty or rough surfaces. In such cases, a separate marking tool is needed. Therefore, current measuring tapes remain inconvenient and cannot meet the needs of measurement and marking in various construction environments. Utility Model Content

[0003] The purpose of this utility model is to provide a measuring tape to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] A measuring tape includes: a measuring tape housing with a measuring tape body wound inside; a measuring aperture is provided on the bottom front side of the measuring tape housing; one end of the measuring tape body extends out of the measuring tape housing from the measuring aperture; an adjusting arc surface is provided on the top front side of the measuring tape housing, the adjusting arc surface being an upwardly arched arc; and a marking module including an arc-shaped adjusting plate, a fixing block, a marking pen, and a marking blade. The bottom surface of the arc-shaped adjusting plate has the same shape as the adjusting arc surface. The arc-shaped adjusting plate is slidably connected to the adjusting arc surface in a left-right direction. The fixing block is connected to the measuring tape housing. The marking pen is connected to one end of the arc-shaped adjusting plate, and the marking blade is connected to the other end of the arc-shaped adjusting plate. The arc-shaped adjusting plate can slide left or right so that the tip of the marking pen moves to one side of the measuring aperture or the tip of the marking blade moves to the other side of the measuring aperture. The fixing block can restrict the sliding of the arc-shaped adjusting plate.

[0006] This technical solution has at least the following beneficial effects: In engineering cost estimation, when dimensional measurement is required, pulling outwards from the end protruding from the measuring tape opening allows the measuring tape body to be pulled out of the measuring tape housing. When marking is needed to achieve the required measurement, a marking pen or marking knife can be used. Specifically, one of the marking pen and marking knife is connected to one end of the arc-shaped adjustment plate, and the other is connected to the other end of the arc-shaped adjustment plate. For example, the marking pen is connected to the left end of the arc-shaped adjustment plate, and the marking knife is connected to the right end. In use, sliding the arc-shaped adjustment plate to the left on the adjustment arc surface of the measuring tape housing causes the marking pen connected to the left end of the arc-shaped adjustment plate to move downwards, while the marking knife on the right end of the arc-shaped adjustment plate moves upwards. When the pen tip moves to the left side of the measuring tape opening, the position of the arc-shaped adjustment plate is locked by the fixing block to restrict its sliding. At this time, the marking pen can be used for measurement marking. Similarly, after releasing the fixing block from restricting the arc-shaped adjustment plate, the arc-shaped adjustment plate is slid to the right on the adjustment arc surface of the measuring tape housing, which allows the marking pen to move upward and the marking knife to move downward. When the tip of the marking knife moves to the right side of the measuring tape opening, the position of the arc-shaped adjustment plate is locked by the fixing block. At this time, the marking knife can be used for measurement marking. In this way, the measuring tape can flexibly select the marking pen or marking knife for marking according to the needs of the construction site, making it more convenient to use. Engineers can directly operate it with one hand, improving the efficiency and accuracy of measurement in engineering cost work.

[0007] As a further improvement to the above technical solution, a limiting piece is connected to one end of the measuring tape body extending from the measuring tape housing, and the limiting piece is perpendicular to the measuring tape body. When the measuring tape body is pulled out of the measuring tape housing for measurement, the limiting piece can be placed against one side of the object to be measured, thereby facilitating the positioning of the extended end of the measuring tape body and improving the user experience.

[0008] As a further improvement to the above technical solution, a through hole is provided on the surface of the measuring tape body near the limiting piece. When it is necessary to draw an arc on the measuring surface, an external fixing component, such as a screw, can be driven into the through hole of the measuring tape body to position one end of the measuring tape body relative to the measuring surface. Then, after pulling the measuring tape body out to the required length, the entire measuring tape body can be rotated around the fixing component, and an arc can be drawn on the measuring surface using a marking pen or marking knife, thus making the overall function more versatile.

[0009] As a further improvement to the above technical solution, the middle part of the fixing block is rotatably connected to the top side of the measuring tape housing. The rotation axis of the fixing block extends in the left-right direction. At least two positioning holes are provided at intervals around the top side of the arc-shaped adjusting plate around the adjusting arc surface. One end of the fixing block can be fitted into any one of the positioning holes. When the arc-shaped adjusting plate needs to slide on the adjusting arc surface, the fixing block moves out of the positioning hole. After the arc-shaped adjusting plate slides to the left or right, the fixing block can be rotated into the positioning hole located on the left or right side for fitting and connection, thereby using the fixing block to achieve sliding locking of the arc-shaped adjusting plate.

[0010] As a further improvement to the above technical solution, the end of the fixing block away from the positioning hole is a pressing part. A protruding fixing post is connected to the top side of the measuring tape housing, directly opposite the pressing part. A spring is sleeved on the outside of the fixing post, and the top of the spring presses upward against the pressing part. The end of the fixing block near the positioning hole can be fitted into the positioning hole. When the fixing block needs to be rotated, force is applied to the pressing part, compressing the spring downward. At this time, the end of the fixing block near the positioning hole disengages outward from the positioning hole. After the arc-shaped adjusting plate slides into place, the pressure on the pressing part is released, and the spring's restoring force pushes the pressing part upward. The end of the arc-shaped adjusting plate near the positioning hole then fits into the positioning hole. This better maintains the sliding restriction of the fixing block on the arc-shaped adjusting plate, further improving the user experience.

[0011] As a further improvement to the above technical solution, one end of the arc-shaped adjusting plate is provided with a fixing hole extending in the vertical direction. A locking bolt is threadedly connected to one end of the arc-shaped adjusting plate. The marking pen is inserted into the fixing hole, and the end of the locking bolt abuts against the marking pen. The marking pen can be installed and removed from the arc-shaped adjusting plate. Specifically, by rotating the locking bolt away from the arc-shaped adjusting plate, the marking pen can be removed from the fixing hole for replacement. The new marking pen can be placed back into the fixing hole, and then the locking bolt is rotated to press against the outside of the marking pen, so that the marking pen is pressed and fixed in the fixing hole.

[0012] As a further improvement to the above technical solution, a mounting base is connected to the bottom surface of the other end of the arc-shaped adjusting plate. The bottom surface of the mounting base has a mounting groove, and the top of the marking blade is inserted into the mounting groove. A locking bolt is connected to the outside of the mounting base, and one end of the locking bolt presses the marking blade tightly into the mounting groove. When it is necessary to adjust the length of the marking blade extension, the locking bolt can be loosened, and the depth of the marking blade's insertion into the mounting groove can be adjusted. After adjustment, the locking bolt is then tightened to press the scale into the mounting groove, thus completing the locking and fixing of the scale.

[0013] As a further improvement to the above technical solution, the top side of the arc-shaped adjusting plate is provided with raised patterns, which extend in the left-right direction and are arranged in multiple patterns around the adjusting arc surface. When engineers need to rotate the arc-shaped adjusting plate, they can apply force more easily by focusing on the raised pattern on the top side of the plate.

[0014] As a further improvement to the above technical solution, a handle is connected to the left or right side of the measuring tape housing. During use, engineers can hold the handle, thereby improving the convenience of measurement and marking. Attached Figure Description

[0018] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connection relationships mentioned herein do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0019] Reference Figure 1A measuring tape includes: a measuring tape housing 1, in which a measuring tape body 11 is wound inside; a measuring aperture is provided on the bottom front side of the measuring tape housing 1; one end of the measuring tape body 11 extends out of the measuring tape housing 1 from the measuring aperture; an adjusting arc surface is provided on the top front side of the measuring tape housing 1, the adjusting arc surface being an upwardly arched arc; and a marking module, which includes an arc-shaped adjusting plate 21, a fixing block 22, a marking pen 23, and a marking knife 24, wherein the bottom surface of the arc-shaped adjusting plate 21 has the same shape as the adjusting arc surface. The arc-shaped adjustment plate 21 is slidably connected to the adjustment arc surface in the left-right direction. The fixing block 22 is connected to the measuring tape housing 1. The marking pen 23 is connected to one end of the arc-shaped adjustment plate 21. The marking blade 24 is connected to the other end of the arc-shaped adjustment plate 21. The arc-shaped adjustment plate 21 can slide to the left or right so that the tip of the marking pen 23 moves to one side of the measuring tape opening or the tip of the marking blade 24 moves to the other side of the measuring tape opening. The fixing block 22 can restrict the sliding of the arc-shaped adjustment plate 21.

[0020] In engineering cost estimation, when dimensional measurements are required, the end extending from the measuring tape opening is pulled outwards, causing the measuring tape body 11 to extend out of the measuring tape housing 1. When marking is needed to reach the required measurement dimension, a marking pen 23 or a marking knife 24 can be used for measurement marking. Specifically, one of the marking pen 23 and the marking knife 24 is connected to one end of the arc-shaped adjustment plate 21, and the other is connected to the other end of the arc-shaped adjustment plate 21. For example, the marking pen 23 is connected to the left end of the arc-shaped adjustment plate 21, and the marking knife 24 is connected to the right end of the arc-shaped adjustment plate 21. In use, sliding the arc-shaped adjustment plate 21 to the left on the adjustment arc surface of the measuring tape housing 1 causes the marking pen 23 connected to the left end of the arc-shaped adjustment plate 21 to move downwards, while the marking knife 24 at the right end of the arc-shaped adjustment plate 21 moves upwards. When the tip of the marking pen 23 moves to the measuring tape opening, the marking knife 24 will move upwards. When the measuring tape is on the left side of the measuring tape opening, the position of the arc-shaped adjustment plate 21 is locked by the fixing block 22 to restrict the sliding of the arc-shaped adjustment plate 21. At this time, the marking pen 23 can be used to make measurement marks. Similarly, after the fixing block 22 is released from the restriction of the arc-shaped adjustment plate 21, the arc-shaped adjustment plate 21 is slid to the right on the adjustment arc surface of the measuring tape housing 1, which allows the marking pen 23 to move upward and the marking blade 24 to move downward. When the tip of the marking blade 24 moves to the right side of the measuring tape opening, the position of the arc-shaped adjustment plate 21 is locked by the fixing block 22. At this time, the marking blade 24 can be used to make measurement marks. In this way, the measuring tape can flexibly select the marking pen 23 or the marking blade 24 for marking according to the needs of the construction site, making it more convenient to use. Engineers can directly operate it with one hand, which improves the efficiency and accuracy of measurement in engineering cost work.

[0021] When measurement is required, the measuring tape body 11 is usually kept parallel to the measuring surface to improve measurement accuracy. To better position the end of the measuring tape body 11, in this embodiment, a limiting piece 111 is connected to the end of the measuring tape body 11 extending from the measuring tape housing 1. The limiting piece 111 is perpendicular to the measuring tape body 11. When the measuring tape body 11 is pulled out of the measuring tape housing 1 for measurement, the limiting piece 111 can be placed against one side of the object to be measured, thus facilitating the positioning of the extended end of the measuring tape body 11 and improving the user experience.

[0022] Furthermore, a through hole 112 is provided on the surface of the measuring tape body 11 near the limiting piece 111. When it is necessary to draw an arc on the measuring surface, an external fixing component, such as a screw, can be driven into the through hole 112 of the measuring tape body 11 to position one end of the measuring tape body 11 relative to the measuring surface. Then, after pulling the measuring tape body 11 out to the required length, the entire measuring tape body 11 can be rotated around the fixing component, and an arc can be drawn on the measuring surface using a marking pen 23 or a marking knife 24, thus making the overall function more versatile.

[0023] There are several ways to lock and restrict the rotation of the arc-shaped adjusting plate 21 by fixing the fixing block 22. For example, the fixing block 22 is threaded onto the measuring tape housing 1 and can press and fix the arc-shaped adjusting plate 21 onto the measuring tape housing 1. Alternatively, multiple pin holes are provided on the arc-shaped adjusting plate 21, and the fixing block 22 is slidably connected to the measuring tape housing 1 in the front-back direction. The fixing block 22 can be engaged in any one of the pin holes to restrict its rotation. In this embodiment, the middle part of the fixing block 22 is rotatably connected to the top side of the measuring tape housing 1, and the rotation axis of the fixing block 22 extends in the left-right direction. The top side of the arc-shaped adjusting plate 21 is provided with at least two positioning holes 211 at intervals around the adjusting arc surface, and one end of the fixing block 22 can be engaged in any one of the positioning holes 211. When the arc-shaped adjustment plate 21 needs to slide on the adjustment arc surface, the fixing block 22 moves out of the positioning hole 211. After the arc-shaped adjustment plate 21 slides to the left or right, the fixing block 22 can be rotated into the positioning hole 211 located on the left or right side for connection, thereby using the fixing block 22 to achieve sliding locking of the arc-shaped adjustment plate 21.

[0024] The end of the fixing block 22 can be tightly fitted with the positioning hole 211, thereby achieving mutual locking and fixation. In order to further maintain the tightness of the fit between the fixing block 22 and the positioning hole 211, in this embodiment, the end of the fixing block 22 away from the positioning hole 211 is a pressing part. A fixing post with an upward protrusion is connected to the top side of the measuring tape housing 1, which is directly opposite the pressing part. A spring is sleeved on the outside of the fixing post, and the top end of the spring presses upward against the pressing part. The end of the fixing block 22 near the positioning hole 211 can be fitted into the positioning hole 211. When the fixing block 22 needs to be rotated, force is applied to the pressing part, and the spring is compressed downward through the pressing part. At this time, the end of the fixing block 22 near the positioning hole 211 disengages out of the positioning hole 211. After the arc-shaped adjusting plate 21 slides into place, the pressure on the pressing part is removed, and the spring force can push the pressing part upward. The end of the arc-shaped adjusting plate 21 near the positioning hole 211 is then fitted into the positioning hole 211. This can better maintain the sliding restriction of the fixing block 22 on the arc-shaped adjusting plate 21, and further improve the user experience.

[0025] As a specific embodiment of the connection between the marker pen 23 and the arc-shaped adjustment plate 21, one end of the arc-shaped adjustment plate 21 is provided with a fixing hole extending in the vertical direction. A locking bolt 13 is threadedly connected to one end of the arc-shaped adjustment plate 21. The marker pen 23 is inserted into the fixing hole, and the end of the locking bolt 13 abuts against the marker pen 23. The marker pen 23 can be installed and removed from the arc-shaped adjustment plate 21. Specifically, by rotating the locking bolt 13 away from the arc-shaped adjustment plate 21, the marker pen 23 can be removed from the fixing hole for replacement. The new marker pen 23 can be placed back into the fixing hole, and then the locking bolt 13 is rotated to press against the outside of the marker pen 23, so that the marker pen 23 is pressed and fixed in the fixing hole.

[0026] As a specific connection embodiment between the marking blade 24 and the arc-shaped adjusting plate 21, a mounting base is connected to the bottom surface of the other end of the arc-shaped adjusting plate 21. The bottom surface of the mounting base is provided with a mounting groove. The top of the marking blade 24 is inserted into the mounting groove. A locking bolt 13 is connected to the outside of the mounting base, and one end of the locking bolt 13 presses the marking blade 24 tightly into the mounting groove. When it is necessary to adjust the extension length of the marking blade 24, the locking bolt 13 can be loosened, and the depth of the top of the marking blade 24 inserted into the mounting groove can be adjusted. After adjustment, the locking bolt 13 is then tightened into the mounting groove to complete the locking and fixing of the scale.

[0027] When it is necessary to rotate the arc-shaped adjusting plate 21, the force is usually applied to the top side of the arc-shaped adjusting plate 21. In order to facilitate the rotation of the arc-shaped adjusting plate 21, in this embodiment, the top side of the arc-shaped adjusting plate 21 is provided with raised patterns. The raised patterns extend in the left-right direction, and multiple raised patterns are arranged around the adjusting arc surface. When the engineer needs to rotate the arc-shaped adjusting plate 21, he can apply force to the raised patterned position on the top side of the arc-shaped adjusting plate 21 to rotate the arc-shaped adjusting plate 21, which makes it easier to apply force.

[0028] In some embodiments, a handle 3 is connected to the left or right side of the measuring tape housing 1. During use, engineers can hold the handle 3, thereby improving the convenience of making measurement marks.

[0029] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
