Description

Technical Field

[0001] This invention relates to the field of indicator technology, and more particularly to a tension indicator. Background Technology

[0002] Currently, it is often necessary to use ropes to secure goods during transportation. However, as trucks bump and shake during operation, friction can easily occur between the ropes and the goods. With continuous friction, the tension of the ropes can decrease, causing them to loosen and the goods to fall off, resulting in safety issues.

[0003] To prevent ropes from loosening, workers check the tightness of the ropes before transporting the goods using traditional tension testers. However, traditional tension testers are manually pressed and rely mainly on human subjective feelings to judge whether the ropes are tight enough. Therefore, using traditional tension testers to check the tightness of ropes is often inaccurate. Summary of the Invention

[0004] The purpose of this invention is to provide a tension indicator that solves the problem of inaccurate detection of rope tension by traditional tension detectors.

[0005] To solve the above-mentioned technical problems, the objective of this invention is achieved through the following technical solution: This invention provides a tension indicator, including an elastic indicator body, the indicator body including an arc-shaped portion, a first indicator piece and a second indicator piece, the first indicator piece and the second indicator piece being connected side by side to both ends of the arc-shaped portion in the radial direction;

[0006] Both ends of the arc-shaped portion in the radial direction are provided with a first protrusion, and the first protrusions at both ends extend in opposite directions.

[0007] The first indicator and the second indicator are each provided with a second protrusion on opposite sides. When the first indicator and the second indicator move away from each other, the second protrusions on both sides separate from each other. When the first indicator and the second indicator move closer to each other, the second protrusions on both sides abut against each other.

[0008] Furthermore, both the first and second indicator plates are tilted in opposite directions.

[0009] Furthermore, the two second protrusions are respectively disposed at the free ends of the first indicator piece and the second indicator piece.

[0010] Furthermore, the two second protrusions are respectively disposed on one side of the first indicator piece and one side of the second indicator piece.

[0011] Furthermore, multiple second protrusions are provided, and each of the multiple second protrusions is respectively provided on the first indicator piece and the second indicator piece.

[0012] Furthermore, one end of the first protrusion is connected to the arc-shaped portion, and the other end of the first protrusion arches relative to the inner arc direction of the arc-shaped portion.

[0013] Furthermore, both the first and second indicator pieces have openings at one end near the arc-shaped portion, and the first protrusion is disposed in the opening.

[0014] Furthermore, multiple first protrusions are provided, and each of the multiple first protrusions is provided at one end of the arc-shaped portion.

[0015] Furthermore, the two opposing first protrusions are separated by a gap.

[0016] Furthermore, the material of the indicator body can be rubber, polyvinyl chloride, polymethyl methacrylate, and polyurethane, etc.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] In this embodiment of the invention, a second protrusion is provided on the first indicator piece and the second indicator piece. When the webbing is tightened and the first and second indicator pieces are brought closer together, the second protrusions of the first and second indicator pieces approach and abut against each other, thereby making it convenient for the user to observe whether the webbing is tightly tied to the goods and improving the safety of truck transportation of goods.

[0028] Please see Figures 1-3 As shown, an embodiment of the present invention provides a tension indicator, including an elastic indicator body 1. The indicator body 1 includes an arc-shaped portion 13, a first indicator piece 11, and a second indicator piece 12. The first indicator piece 11 and the second indicator piece 12 are connected side by side to both ends of the arc-shaped portion 13 in the radial direction. A first protrusion 14 is provided at both ends of the arc-shaped portion 13 in the radial direction, and the first protrusion 14 at both ends extends in a direction opposite to each other. A second protrusion 15 is provided on the opposite side of the first indicator piece 11 and the second indicator piece 12. When the first indicator piece 11 and the second indicator piece 12 move away from each other, the second protrusions 15 on both sides separate from each other. When the first indicator piece 11 and the second indicator piece 12 move closer to each other, the second protrusions 15 on both sides abut against each other.

[0029] In this embodiment, the tension indicator of the present invention is applied to a pulling machine (not shown in the figure). The pulling machine includes a crossbar and a webbing. The indicator body 1 is located between the crossbar and the webbing. The indicator body 1 is fitted onto the crossbar through an arc-shaped portion 13 (i.e., the crossbar is located in the arc opening of the arc-shaped portion 13). By providing first protrusions 14 at both ends of the arc-shaped portion 13, the first protrusions 14 cooperate with the crossbar to limit the movement, thereby preventing the indicator body 1 from falling off the crossbar and ensuring the stability of the tension indicator installed on the crossbar. The webbing passes around one of the indicator pieces of the indicator body 1 through the arc-shaped portion 13, and then passes around the other indicator piece through the arc-shaped portion 13, so that the indicator body 1 is covered by the webbing in the annular opening formed by the webbing. When the webbing is not tightened, the indicator body 1 is located in the annular opening formed by the webbing, and the first indicator piece 11 and the second indicator piece 12 are not subjected to compressive force. The first indicator piece 11 and the second indicator piece 12 are far apart from each other, that is, the two second protrusions 15 are separated from each other (e.g., Figure 1 and Figure 2 (As shown); When the webbing tightens, the annular opening formed by the webbing shrinks. Because the indicator body 1 is elastic, the tightening of the webbing compresses the indicator body 1, causing the first indicator piece 11 and the second indicator piece 12 to move closer together. The second protrusion 15 of the first indicator piece 11 and the second protrusion 15 of the second indicator piece 12 then come into contact with each other and abut against each other (as shown). Figure 3 (As shown); With this configuration, users can determine whether the webbing is tightened based on whether the two second protrusions 15 abut against each other, thereby improving the safety of trucks transporting goods.

[0030] Please see Figure 2 As shown, in one embodiment, the first indicator piece 11 and the second indicator piece 12 are both tilted in opposite directions.

[0031] In this embodiment, the first indicator piece 11 and the second indicator piece 12 are inclined, so that the gap between the first indicator piece 11 and the second indicator piece 12 gradually decreases from one end to the other. One end of the first indicator piece 11 and the second indicator piece 12 is the end connected to the arc-shaped portion 13. The reduced gap between the first indicator piece 11 and the second indicator piece 12 brings them closer together, that is, the distance between the two second protrusions 15 is closer. When the webbing is tightened, the two second protrusions 15 can more easily come together and support each other. Compared to a setting where the two second protrusions 15 are farther apart, when the webbing is tightened, the first indicator piece 11 and the second indicator piece 12 can be prevented from breaking due to tensile strength, thus increasing the service life of the indicator body 1.

[0032] In a more specific embodiment, two second protrusions 15 are respectively disposed at the free end of the first indicator piece 11 and the free end of the second indicator piece 12.

[0033] In this embodiment, since the first indicator piece 11 and the second indicator piece 12 are arranged at an angle, the distance between the free end of the first indicator piece 11 and the free end of the second indicator piece 12 is closer than the distance between other parts. The two second protrusions 15 are respectively located at the free ends of the first indicator piece 11 and the second indicator piece 12. When the webbing is tightened, the two second protrusions 15 can more easily approach and support each other, reducing the compression of the first indicator piece 11 and the second indicator piece 12 by the webbing and improving the service life of the first indicator piece 11 and the second indicator piece 12.

[0034] In one embodiment, two second protrusions 15 are respectively disposed on one side of the first indicator piece 11 and one side of the second indicator piece 12.

[0035] In this embodiment, the two second protrusions 15 are located on one side of the first indicator piece 11 and the second indicator piece 12, respectively. This arrangement allows the user to better observe from the side of the indicator body 1 when the webbing is tightened and the two second protrusions 15 move closer to each other.

[0036] In one embodiment, a plurality of second protrusions 15 are provided, and the plurality of second protrusions 15 are respectively disposed on the first indicator piece 11 and the second indicator piece 12.

[0037] In this embodiment, multiple second protrusions 15 are provided, and they can be distributed between the two sides of the first indicator plate 11 and the two sides of the second indicator plate 12. With this arrangement, when the webbing is tightened, the multiple second protrusions 15 can abut against each other, making it easier for the user to observe whether the webbing is tightened. Preferably, four second protrusions 15 are provided in this invention. The second protrusions 15 are arranged in pairs on one side and the other side of the first indicator plate 11, and on one side and the other side of the second indicator plate 12. With this arrangement, when the webbing is tightened, the user can easily observe whether the second protrusions 15 are abutting on both sides of the first indicator plate 11 and the second indicator plate 12, thereby improving the accuracy of determining the tightening of the webbing.

[0038] In one embodiment, one end of the first protrusion 14 is connected to the arcuate portion 13, and the other end of the first protrusion 14 arches relative to the inner arc direction of the arcuate portion 13.

[0039] In this embodiment, the first protrusion 14 arches to form a first protrusion 14 with an arc. When the indicator body 1 is fitted onto the crossbar through the arc-shaped part 13, the crossbar has a cylindrical structure. The first protrusion 14 with an arc can better adapt to the cylindrical shape of the crossbar, so that the indicator body 1 can be stably fitted onto the crossbar through the arc-shaped part 13 and the first protrusion 14, ensuring that the indicator body 1 will not fall off the crossbar and improving the stability of the indicator body 1 in operation.

[0040] In one embodiment, the first indicator piece 11 and the second indicator piece 12 are both provided with an opening 16 at one end near the arc-shaped portion 13, and the first protrusion 14 is disposed in the opening 16.

[0041] In this embodiment, the opening 16 provides space for the first protrusion 14, reducing the material on the first indicator piece 11 and the second indicator piece 12, thereby reducing the weight of the indicator body 1, saving production materials, and reducing the production cost of the indicator body 1.

[0042] In one embodiment, a plurality of first protrusions 14 are provided, and the plurality of first protrusions 14 are provided one-to-one at both ends of the arc-shaped portion 13.

[0043] In this embodiment, when the indicator body 1 is fitted onto the crossbar, the multiple first protrusions 14 contact the crossbar, thereby improving the stability of the indicator body 1 fitted onto the crossbar and ensuring that the indicator body 1 will not fall off the crossbar when the webbing is tightened, thus improving the stability of the indicator body 1 installation.

[0044] In one embodiment, the two opposing first protrusions 14 are separated by a gap.

[0045] In this embodiment, when the indicator body 1 needs to be removed from the crossbar, the first indicator piece 11 and the second indicator piece 12 can be moved away from each other, thereby enlarging the channel between the two first protrusions 14 until the crossbar can pass through the channel. In this way, the indicator body 1 can be removed from the crossbar for user replacement or maintenance.

[0046] In one embodiment, the material of the indicator body 1 can be rubber, polyvinyl chloride, polymethyl methacrylate, polyurethane, etc.

[0047] In this embodiment, the present invention does not limit the selection of the material of the indicator body 1. Users can select it according to the production cost or their own needs, as long as the indicator body 1 has the function of elastic deformation.

[0048] This invention provides a tension indicator that allows users to easily and accurately determine whether the webbing is tightly secured to the goods. A second protrusion 15 is provided on the first indicator piece 11 and the second indicator piece 12. When the webbing tightens and squeezes the indicator body 1, the first indicator piece 11 and the second indicator piece 12 move closer together, causing the second protrusion 15 on the first indicator piece 11 and the second protrusion 15 on the second indicator piece 12 to abut against each other. This allows for accurate determination of whether the webbing is tightly secured to the goods, improving the safety of goods transported by truck. Furthermore, the tension indicator has a first protrusion 14 at the position of the arc-shaped portion 13. When the indicator body 1 is mounted on a crossbar, the first protrusion 14 can cooperate with the crossbar to limit its movement, thereby preventing the indicator body 1 from falling off the crossbar and improving the stability of the indicator body 1 during operation.

[0049] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
