Description

Technical Field

[0001] The utility model relates to the field of measuring tools, and more specifically, to a rapid measuring tool for the angle of a tire belt layer. Background Art

[0002] The belt layer angle has an important impact on the safety performance, high-speed performance, comfort, etc. of tires. During the design stage and mass production stage of tires, each tire enterprise will take samples of each batch of produced tires for analysis. Among them, cross-section analysis is to analyze the dimensions of the internal skeleton materials, rubber materials, component distribution, etc. of the tires to verify whether the design is consistent with the actual production. Currently, when tire enterprises measure the angle of the tire belt layer, they usually measure it with a protractor after dissecting the tire. This measurement method can only be carried out after dissecting the tire, resulting in a time-consuming and laborious testing process, low testing efficiency, and the shape of the belt layer steel wires peeled off from the dissected tire will change, resulting in a deviation from the belt layer angle in the tire. For this reason, the application number: CN201921928231.3 discloses a measuring device for the angle of tire belt layer steel cord. The measuring device includes a semi-circular angle plate, conductive lines, a measuring arm, and a multimeter. The semi-circular edge of the semi-circular angle plate is a resistive material with uniform conductivity. The conductive lines are installed on the central axis of the semi-circular angle plate. The top end of the conductive lines is connected to the central part of the resistive material. A first conductive column is installed on the back of the semi-circular angle plate, and the first conductive column is connected to the bottom end of the conductive lines. The bottom end of the measuring arm is rotatably installed at the center of the semi-circular angle plate. The measuring arm is provided with a section of conductive material, and the conductive material is in contact with the resistive material. A second conductive column is installed on the measuring arm, and the second conductive column is connected to the conductive material.

Specific embodiments

[0022] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: a rapid measuring tool for the angle of the tire belt layer, including a semi - circular scale plate 1. One end of a rotating rod 2 is rotatably connected to the center of the surface of the semi - circular scale plate 1 with scale lines. The rotating rod 2 includes a first rod body 201 and a second rod body 202. An inserting rod 204 is provided on the surface of the first rod body 201 facing the second rod body 202. An inward - concave slot 205 is formed on the surface of the second rod body 202 facing the first rod body 201. The inserting rod 204 and the slot 205 are connected in a matching manner. On both sides of the slot 205 on the surface of one end of the second rod body 202, L - shaped extensions 206 are integrally provided. Jacks 207 are formed on the opposite surfaces of the two L - shaped extensions 206. The jacks 207 are connected to a telescopic rotating mechanism provided at one end of the inserting rod 204. A sliding guide rail 203 is formed on one side surface of the first rod body 201. A conductive measuring head 3 is slidably installed in the sliding guide rail 203. A limiting boss 101 is integrally provided on the bottom surface of the semi - circular scale plate 1. A measuring conductive antenna 4 is provided on one side surface of the limiting boss 101. A power supply 7 is also fixedly installed on one side surface of the first rod body 201. The power supply 7 is electrically connected to the measuring conductive antenna 4 and the conductive measuring head 3 respectively.

[0024] Please refer to Figure 4 , on one side surface of each L - shaped extension 206, a guiding chute 208 extending to the inner wall of the slot 205 is also provided. One end of each guiding chute 208 communicates with the corresponding jack 207, and the depth is less than the depth of the jack 207.

[0025] When the insertion rod 204 is inserted into the slot 205, the rotating structure is located in the guiding chute 208 inside the slot 205. When it is necessary to fold and store the whole rotating rod 2, when the first rod body 201 is pulled outwards, the rotating structure slides in the guiding chute 208 and finally inserts into the jack 207, enabling the whole first rod body 201 to rotate independently relative to the second rod body 202, thus completing the folding of the whole rotating rod 2, reducing the bending of the rotating rod 2 when not in use, prolonging the overall service life and measurement accuracy. In the actual use process, magnets can be arranged at the ends of the first rod body 201 and the second rod body 202 close to one end, so that when the first rod body 201 and the second rod body 202 are spliced in the folding box, they can be limited by magnetic attraction to ensure stability during use.

[0026] Further, the rotating mechanism includes an installation through hole opened on one side surface of the slot 205. Both ends of the installation through hole are slidably connected with rotating shafts 209, and both ends of a spring 210 are respectively fixedly connected to the opposite end surfaces of the two rotating shafts 209.

[0027] Both ends of the two rotating shafts 209 are located in the corresponding guiding chutes 208. The rotating shafts 209 and the guiding chutes 208 are slidably matched to guide the pulling out and installation of the first rod body 201. When the ends of the rotating shafts 209 are located in the corresponding jacks 207, under the action of the spring 210, the two rotating shafts 209 slide outwards and insert into the deeper jacks 207 to connect and limit the first rod body 201, and serve as a rotating shaft to support the rotation and folding of the first rod body 201. An inclined surface is provided at the end of each rotating shaft 209 facing the connection of the guiding chute 208 and the jack 207, so as to facilitate the end of the rotating shaft 209 to return from the jack 207 to the corresponding guiding chute 208.

[0028] Please refer to Figure 5 , the conductive measuring head 3 includes an L-shaped mounting plate 301. A sliding column 302 is integrally provided on one side surface of the L-shaped mounting plate 301. The sliding column 302 is slidably connected in the sliding guide rail 203. A measuring brush 303 is fixedly installed on one side inner wall of the L-shaped mounting plate 301, and the measuring brush 303 is electrically connected to the power supply 7.

[0029] According to the size of the tire end face, the whole L-shaped mounting plate 301 slides independently relative to the first rod body 201 through the sliding column 302 to adjust the position of the measuring brush 303. After the measuring conductive antenna 4 contacts one end of a steel wire in the belt layer of the tire end face, the whole rotating rod 2 can be rotated to drive the measuring brush 303 to perform a circumferential movement. When the measuring brush 303 contacts the other end of the corresponding steel wire, the circuit is connected, and the position of the steel wire can be determined. At this time, by observing the scale line on one side surface of the semi-circular scale plate 1 and the corresponding position of the rotating rod 2, the angle of the steel wire can be obtained, and the use is relatively convenient and simple.

[0030] Furthermore, the diameter of the sliding column 302 is the same as the distance between the inner walls on both sides of the sliding guide rail 203.

[0031] When the diameter of the sliding column 302 is the same as the distance between the inner walls of the sliding guide rail 203, it can ensure the connection stability, enabling the overall L-shaped mounting plate 301 to slide relative to the first rod body 201. At the same time, the sliding column 302 can rotate in the sliding guide rail 203, so that the angle of the overall conductive measuring head 3 can be independently adjusted, and can be adjusted according to the actual situation of the tire end face, reducing the limitations in use.

[0032] Please refer to Figures 1 to 3 , the measuring conductive antenna 4 is inserted into the sliding seat 401, and the sliding seat 401 is slidably connected in the N-shaped groove 402, and the N-shaped groove 402 is opened on one side surface of the semi-circular scale plate 1.

[0033] The sliding seat 401 is slidably connected in the N-shaped groove 402, so that the position of the measuring conductive antenna 4 can be independently adjusted, and can also be adjusted according to the actual situation of the tire end face, further reducing the limitations in the use process.

[0034] Furthermore, an indicator light 5 and a voice prompt module 6 are also installed on one side surface of the second rod body 202, and the measuring brush 303, the measuring conductive antenna 4, the indicator light 5, the voice prompt module 6 and the power supply 7 are electrically connected in series.

[0035] When the measuring conductive antenna 4 and the measuring brush 303 respectively contact both ends of a steel wire in the belt layer and the circuit is connected, the indicator light 5 and the voice prompt module 6 can work. When the indicator light 5 lights up, the voice prompt module 6 emits a beeping alarm sound or a voice reading to prompt the user that the circuit is connected, which is suitable for novice users and increases the applicable scenarios.

[0036] Furthermore, an observation port 8 is also opened on one side surface of the second rod body 202 corresponding to the circumferential scale line area of the semi-circular scale plate 1.

[0037] By opening the observation port 8 on the second rod body 202, it is more convenient to read the overall angle of the rotating rod 2, improving the measurement accuracy.

[0038] Working principle: The semi-circular scale plate 1 is closely attached to the tire cross-section, and the measuring conductive antenna 4 is made to contact one end of a steel wire in the cross-section belt layer. According to the tire end face situation, the L-shaped mounting plate 301 is slid by the sliding column 302 so that the measuring brush 303 can contact the other side of the cross-section. The rotating rod 2 is rotated to drive the measuring brush 303 to perform a circumferential movement. When the measuring brush 303 contacts the other end of the corresponding steel wire, the circuit is connected, and the indicator light 5 and the voice prompt module 6 work simultaneously to give an acoustic and optical prompt to the user to determine the position of the steel wire. At this time, the angle of the rotating rod 2 can be observed through the observation port 8, and the measurement process is relatively simpler and faster. When the device is not in use, the first rod body 201 can be pulled outwards to separate the insertion rod 204 from the slot 205. At this time, the ends of the two rotating shafts 209 slide in the corresponding guiding chutes 208 to the L-shaped extension part 206 and finally insert into the corresponding jacks 207, and the first rod body 201 can perform independent rotation relative to the second rod body 202 to complete the folding of the entire rotating rod 2, avoiding the overall bending deformation of the rotating rod 2 when not in use, which affects the overall service life and measurement accuracy.

[0039] It should be noted that the specific model specifications of the measuring brush 303, the indicator light 5, the voice prompt module 6, and the power supply 7 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0040] The power supply and its principle of the measuring brush 303, the indicator light 5, the voice prompt module 6, and the power supply 7 are clear to those skilled in the art and will not be described in detail here.

[0041] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
