Description

Technical Field

[0001] The utility model relates to the technical field of indicators, in particular to a tension indicator. Background Art

[0002] At present, ropes are often needed to tie goods during transportation. Since the truck will bump and shake during driving, friction is likely to occur between the rope and the goods. As the friction continues to generate, the tension of the rope is likely to decrease, and the rope is likely to loosen, causing the goods to scatter, resulting in safety problems.

[0003] To prevent the ropes from loosening, workers use traditional tension testers to check whether the ropes are tied tightly to the cargo before transportation. However, traditional tension testers are manually pressed and mainly rely on people's subjective feelings to judge whether the ropes are tied tightly to the cargo. Therefore, using traditional tension testers to check whether the ropes are tied tightly to the cargo is often inaccurate. Utility Model Content

[0007] A second protrusion is provided on one side opposite to the first indicator piece and the second indicator piece. When the first indicator piece and the second indicator piece move away from each other, the second protrusions on both sides separate from each other. When the first indicator piece and the second indicator piece move closer to each other, the second protrusions on both sides abut against each other.

[0008] Furthermore, the first indicator piece and the second indicator piece are both inclined in directions opposite to each other.

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

[0028] See also Figures 1 to 3 As shown, an embodiment of the utility model provides a tension indicator, including an elastic indicator body 1, the indicator body 1 including 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 in parallel to the two ends of the arc-shaped portion 13 in the radial direction; both ends of the arc-shaped portion 13 in the radial direction are provided with a first protrusion 14, and the first protrusions 14 at both ends extend in directions opposite to each other; the first indicator piece 11 and the second indicator piece 12 are provided with a second protrusion 15 on the opposite side, 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, and when the first indicator piece 11 and the second indicator piece 12 move close 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), which includes a crossbar and a webbing, and the indicator body 1 is located between the crossbar and the webbing. The indicator body 1 is mounted on the crossbar through the arc portion 13 (that is, the crossbar is located in the arc opening of the arc portion 13). By arranging first protrusions 14 at both ends of the arc portion 13, the first protrusions 14 cooperate with the crossbar to limit the position, which can prevent the indicator body 1 from falling off the crossbar, thereby ensuring the stability of the tension indicator installed on the crossbar; the webbing passes around the arc portion 13 from one of the indicator pieces of the indicator body 1, and then the webbing passes around the other indicator piece from the arc 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 will not be subjected to extrusion force, and the first indicator piece 11 and the second indicator piece 12 are away from each other, that is, the two second protrusions 15 are separated from each other (such as Figure 1 and Figure 2 As shown); when the webbing is tightened, the annular opening around which the webbing is wound is reduced. Since the indicator body 1 is elastic, the webbing can squeeze the indicator body 1 when it is tightened, so that the first indicator sheet 11 and the second indicator sheet 12 are close to each other, and the second protrusion 15 of the first indicator sheet 11 and the second protrusion 15 of the second indicator sheet 12 are close to each other and abut against each other (as shown); Figure 3 With this arrangement, the user can judge whether the webbing is tightened based on whether the two second protrusions 15 are in contact with each other, thereby improving the safety of the goods transported by the truck.

[0030] See also Figure 2 As shown, in one embodiment, the first indicator piece 11 and the second indicator piece 12 are inclined in directions opposite to each other.

[0031] In this embodiment, the first indicator piece 11 and the second indicator piece 12 are arranged at an angle, so that the gap between the first indicator piece 11 and the second indicator piece 12 gradually decreases from one end to the other, wherein 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 narrowing gap between the first indicator piece 11 and the second indicator piece 12 brings the first indicator piece 11 and the second indicator piece 12 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 close to each other and abut against each other. Compared with an arrangement where the two second protrusions 15 are far 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, thereby improving the service life of the indicator body 1.

[0032] In a more specific embodiment, the two second protrusions 15 are respectively provided 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 that of other parts, wherein the two second protrusions 15 are respectively located at the free end of the first indicator piece 11 and the free end of the second indicator piece 12. When the webbing is tightened, the two second protrusions 15 can be more easily approached and abutted, thereby reducing the squeezing of the webbing on the first indicator piece 11 and the second indicator piece 12, and improving the service life of the first indicator piece 11 and the second indicator piece 12.

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

[0035] In this embodiment, the two second protrusions 15 are respectively located on one side of the first indicator piece 11 and the second indicator piece 12. Such a configuration facilitates the user to better observe from the side of the indicator body 1 when the webbing is tightened and drives the two second protrusions 15 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 provided on the first indicator sheet 11 and the second indicator sheet 12 in a one-to-one correspondence.

[0037] In this embodiment, a plurality of second protrusions 15 are provided, and they can be distributed between the two sides of the first indicator piece 11 and between the two sides of the second indicator piece 12, respectively. With this arrangement, when the webbing is tightened, the plurality of second protrusions 15 can abut against each other, so that the user can more easily observe whether the webbing is tightened; the second protrusions 15 in the utility model are preferably provided with four, and the second protrusions 15 are correspondingly arranged on one side and the other side of the first indicator piece 11, and on one side and the other side of the second indicator piece 12. With this arrangement, when the webbing is tightened, the user can conveniently observe whether the second protrusions 15 abut against each other on both sides of the first indicator piece 11 and the second indicator piece 12, thereby improving the accuracy of judging whether the webbing is tightened.

[0038] In one embodiment, one end of the first protruding portion 14 is connected to the arc-shaped portion 13 , and the other end of the first protruding portion 14 is arched relative to the inner arc direction of the arc-shaped portion 13 .

[0039] In this embodiment, the first protrusion 14 is arched to form a first protrusion 14 with an arc. When the indicator body 1 is mounted on the crossbar through the arc-shaped portion 13, wherein the crossbar is a cylindrical structure, the first protrusion 14 with an arc can be more adapted to the cylindrical shape of the crossbar, so that the indicator body 1 can be stably mounted on the crossbar through the arc-shaped portion 13 and the first protrusion 14, ensuring that the indicator body 1 will not fall off the crossbar, thereby improving the working stability of the indicator body 1.

[0040] In one embodiment, an opening 16 is formed at one end of the first indicator piece 11 and the second indicator piece 12 close to 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 arrangement of 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 protruding portions 14 are provided, and the plurality of first protruding portions 14 are disposed at both ends of the arc-shaped portion 13 in a one-to-one corresponding manner.

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

[0044] In one embodiment, a gap is formed between the two opposing first protrusions 14 .

[0045] In this embodiment, when the indicator body 1 needs to be removed from the cross piece, the first indicator piece 11 and the second indicator piece 12 can be moved away from each other, so that the channel between the two first protrusions 14 becomes larger until the cross piece can pass through the channel. In this way, the indicator body 1 can be removed from the cross piece 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 impose any restrictions on the selection of the material of the indicator body 1 , and the user can select the material based on the production cost or his own needs. It only needs that the indicator body 1 has the function of elastic deformation.

[0048] The present invention provides a tension indicator, which can help users accurately judge whether the webbing is tied tightly to the goods. Second protrusions 15 are provided on the first indicator piece 11 and the second indicator piece 12. When the webbing is tightened and squeezes the indicator body 1, the first indicator piece 11 and the second indicator piece 12 approach each other, so that the second protrusion 15 on the first indicator piece 11 and the second protrusion 15 on the second indicator piece 12 abut against each other, thereby accurately judging whether the webbing is tied tightly to the goods, thereby improving the safety of goods transported by trucks; in addition, the tension indicator is provided with a first protrusion 14 at the position of the arc portion 13. When the indicator body 1 is installed on the cross bar, the first protrusion 14 can cooperate with the cross bar to limit the position, thereby preventing the indicator body 1 from falling off the cross bar, thereby improving the working stability of the indicator body 1.

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