Description

Technical Field

[0001] This invention relates to the field of measuring device technology, specifically to a center distance measuring device for fishing gear components. Background Technology

[0002] A fishing reel is a common type of fishing tackle. Also known as a line reel, line feeder, or, in ancient times, a fishing cart, it's an essential piece of fishing gear for casting (sea) rod fishing. It typically consists of 11 main components: a handle, crank arm, anti-reverse button, main body, reel feet, guide reel, line reel, casting nut, hook clip, line housing, and drag system. Fixed to the front of the casting rod handle, it forms the core of a casting rod rig. When manufacturing a fishing reel, the center distance between the handle mounting hole and the main shaft mounting hole needs to be measured.

[0003] The existing device has a complicated procedure for measuring the center distance. When measuring the points separately, it is easy to accumulate various errors such as positioning errors and assembly errors, resulting in insufficient measurement accuracy and installation errors.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a center distance measuring device for fishing gear components. Summary of the Invention

[0005] The purpose of this invention is to provide a center distance measuring device for fishing gear components to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a center distance measuring device for fishing tackle components, comprising a platform and a measuring component. A notch is provided at one corner of the platform. The measuring component is disposed on both sides of the platform. The measuring component includes a base, a reflector, a support plate, a connecting ring, a central rod, a measuring plate, a horizontal mechanism, a rangefinder, a collar, and a lifting rod. Bases are provided on both sides of the platform, and a reflector is connected to one side of the platform. A support plate is connected to one side of the base, and a connecting ring is rotatably connected to the end of the support plate away from the base. A central rod is connected to the center of the connecting ring, and a measuring plate is connected to the end of the central rod away from the connecting ring. A horizontal mechanism is connected to the center of the measuring plate, and a rangefinder is connected below the measuring plate. A collar is sleeved on the center of the central rod, and a lifting rod is connected to the side of the collar closest to the base.

[0007] Furthermore, the two bases are distributed horizontally and vertically about the platform, respectively, and the two reflectors are perpendicular to the axis of the central rod. The central rod is slidably connected to the collar and is rotatably connected to the support plate through the connecting ring. The horizontal mechanism includes a laser emitter and a receiver.

[0008] Furthermore, the platform has a sliding groove below the horizontally distributed base, and a slider is engaged in the sliding groove. A push rod is connected between the horizontally distributed base and the corresponding reflector on the platform, and the slider is connected to the base.

[0009] Furthermore, the bases distributed longitudinally on the platform are symmetrically connected to limit blocks in front, and limit springs are symmetrically connected inside the limit blocks. The other end of the limit spring is connected to a limit card, and the limit card is engaged and slidably connected to the limit block. The limit card is elastically connected to the limit block through the limit spring.

[0010] Furthermore, the bases distributed longitudinally on the platform have symmetrically provided limit grooves at their four corners, and limit rods are provided in the limit grooves. The upper end of the limit rod is connected to a support plate, and support springs are symmetrically connected below the support plate.

[0011] Furthermore, the limiting rod is slidably connected to the base through the limiting groove, and the supporting spring is connected to the base, while the supporting plate is elastically connected to the base through the supporting spring.

[0012] Furthermore, the upper end of the longitudinally distributed reflectors on the table is connected to a crossbeam, and a push rod is connected between the support plate and the reflectors. The surface of the crossbeam is symmetrically provided with slide rails, and protrusions are engaged and slidably connected inside the slide rails. The protrusions are connected to the support plate.

[0013] Furthermore, a clamping assembly is provided at the end of the central rod away from the measuring plate. The clamping assembly includes a support rod and a through groove. The end of the central rod away from the measuring plate is connected to the support rod, and the surface of the support rod is provided with a through groove. There are two through grooves, and the through direction of the through grooves is perpendicular to each other on the support rod.

[0014] Furthermore, the clamping assembly also includes an adjusting spring, a top plate, a connecting rod, and a limiting block. The adjusting spring is symmetrically connected to the support rod, and the other end of the adjusting spring is connected to the top plate. The connecting rod is rotatably connected in the through groove, and the two ends of the connecting rod are rotatably connected to the limiting block.

[0015] Furthermore, the clamping assembly also includes a guide plate and a limiting strip. The guide plate is rotatably connected to the end of the top plate away from the central rod, and the limiting strip is symmetrically connected to the side of the top plate near the support rod. The limiting block is engaged and slidably connected to the top plate through the limiting strip.

[0016] This invention provides a center distance measuring device for fishing tackle components, which has the following advantages: it can clamp fishing reels of different specifications and automatically adjust the fishing reels during testing, so that the holes on both sides are horizontal with the table surface, which facilitates the measurement of the center distance of the holes.

[0017] 1. In use, after the fishing reel is clamped, the lifting rod on the base moves the collar, thereby causing the center rod to rotate on the support plate via the connecting ring, adjusting the fishing reel. The transmitter on the horizontal mechanism emits laser light towards the reflector, and the receiver receives the light reflected back from the reflector. When the receiver can receive the light emitted by the corresponding transmitter, since the center line of the measuring plate coincides with the center line of the center rod, it indicates that the center lines of the holes where the two center rods are located are parallel to the table surface. Furthermore, since the two measuring plates are the same size, the rangefinder detects the distance between the measuring plate and the table surface. The center distance between the two holes can be obtained by the difference between the two measurement data. When the center rod is rotated, because the inner diameter of the collar is larger than the outer diameter of the center rod, the collar will not obstruct the rotation of the center rod. In summary, in use, the fishing reel can be automatically adjusted so that the holes on both sides are horizontal to the table surface, facilitating the measurement of the center distance between the holes.

[0018] 2. In this invention, when fixing the fishing reel, the mounting base of the fishing reel is first placed between the limiting clips, and the fishing reel is inserted into the clamping assembly. Then, the fishing reel is pushed so that the limiting clips, under the action of the limiting spring, restrict the mounting base of the fishing reel, preventing the fishing reel from rotating freely on the clamping assembly. Then, the push rod can drive the support plate to move below the crossbeam, thereby driving the longitudinal base to move above the platform through the limiting rod, moving another hole to another clamping assembly. The protrusion can restrict the support plate through the slide rail to prevent the support plate from tilting. Then, the push rod can drive the transverse base... The base is placed close to the fishing reel, and its clamping assembly is inserted into another hole of the fishing reel. During insertion, the clamping assembly squeezes the fishing reel, causing the base to stretch or compress the support spring, ensuring that the clamping assembly can be fully inserted. During insertion, the limiting rod can restrict the base through the limiting groove. At the same time, the clamping assembly can drive the center rod to rotate according to the inclination of the hole at this time, and the slider can restrict the base through the sliding groove to prevent it from tilting during movement. In summary, during use, the entire fishing reel can be automatically clamped, which is convenient for subsequent adjustment.

[0019] 3. When the clamping assembly is inserted into the hole, the edge of the hole contacts the guide plate, which applies pressure to the guide plate, causing it to rotate on the top plate and move closer to the support rod. This compresses the adjusting spring, making the distance between the center lines of the top plate and the support rod equal to the inner diameter of the hole. As the top plate moves, it drives the limiting block to slide inside the limiting strip and drives the connecting rod to rotate in the through groove, thus enabling the relative top plates to move synchronously and maintaining the stability of the top plates. This ensures that all top plates are pressed tightly into the hole under the action of the adjusting spring. The device is mounted on a wall, allowing the fishing reel to be clamped through holes. During clamping, the center lines of the holes, support rod, and center rod are aligned, facilitating subsequent adjustments and measurements. Adjustable springs allow the clamping assembly to hold fishing reels of different sizes, enhancing the device's versatility. After testing, the clamping assembly can be removed from the holes without obstructing unloading of the fishing reel, as the base resets. In summary, the device can clamp fishing reels of different sizes and maintain stable clamping during use. Attached Figure Description

[0028] Please see Figures 1 to 7 The present invention provides a technical solution: a center distance measuring device for fishing gear components, comprising a platform 1 and a measuring component 3. A notch 2 is provided at one corner of the platform 1. The measuring component 3 is disposed on both sides of the platform 1. The measuring component 3 includes a base 301, a reflector 302, a support plate 303, a connecting ring 304, a center rod 305, a measuring plate 306, a horizontal mechanism 307, a rangefinder 308, a collar 309, and a lifting rod 310. The base 301 is disposed on both sides of the platform 1, and a reflector 302 is connected to one side of the base 301 on the platform 1. 2. A support plate 303 is connected to one side of the base 301, and a connecting ring 304 is rotatably connected to the end of the support plate 303 away from the base 301. A central rod 305 is connected to the middle of the connecting ring 304, and a measuring plate 306 is connected to the end of the central rod 305 away from the connecting ring 304. A horizontal mechanism 307 is connected to the center of the measuring plate 306, and a rangefinder 308 is connected to the bottom of the measuring plate 306. A collar 309 is sleeved in the middle of the central rod 305, and a lifting rod 310 is connected to the side of the collar 309 near the base 301.

[0029] Please see Figures 1 to 5Two bases 301 are distributed horizontally and vertically about the platform 1, respectively, and two reflectors 302 are perpendicular to the axis of the central rod 305. The central rod 305 is slidably connected to the collar 309, and the central rod 305 is rotatably connected to the support plate 303 through the connecting ring 304. The horizontal mechanism 307 includes a laser emitter and a receiver. The platform 1 has a groove 4 below the horizontally distributed bases 301, and a slider 5 is engaged in the groove 4. A push rod 6 is connected between the horizontally distributed bases 301 and the corresponding reflectors 302 on the platform 1, and the slider 5 is connected to the base 301. Limiting blocks 7 are symmetrically connected in front of the vertically distributed bases 301 on the platform 1, and limiting springs 8 are symmetrically connected in the limiting blocks 7. The other end of the limiting spring 8 is connected to a limiting clip 9, and the limiting clip 9 is connected to the limiting block 7. The table surface 1 has a sliding connection, and the limiting card 9 is elastically connected to the limiting block 7 through the limiting spring 8. The four corners of the base 301 distributed longitudinally on the table surface 1 are symmetrically provided with limiting grooves 10, and the limiting grooves 10 are provided with limiting rods 11. The upper end of the limiting rod 11 is connected to the support plate 12, and the lower part of the support plate 12 is symmetrically connected with the support spring 13. The limiting rod 11 is slidably connected to the base 301 through the limiting groove 10, and the support spring 13 is connected to the base 301. The support plate 12 is elastically connected to the base 301 through the support spring 13. The upper end of the reflector 302 distributed longitudinally on the table surface 1 is connected to the crossbeam 14, and the support plate 12 and the reflector 302 are connected with the push rod 15. The surface of the crossbeam 14 is symmetrically provided with slide rails 16, and the slide rails 16 are slidably connected with protrusions 17, which are connected to the support plate 12.

[0030] The specific operation is as follows: During use, after clamping the fishing reel, the lifting rod 310 on the base 301 can move the collar 309, thereby causing the center rod 305 to rotate on the support plate 303 via the connecting ring 304, adjusting the fishing reel. The transmitter on the horizontal mechanism 307 emits laser light towards the reflector 302, and the receiver receives the light reflected back from the reflector 302. When the receivers can receive the light emitted by the corresponding transmitters, since the center line of the measuring plate 306 coincides with the center line of the center rod 305, it indicates that the center lines of the holes where the two center rods 305 are located are parallel to the platform 1. Because the two measuring plates 306 are the same size, the rangefinder 308 detects the distance between the measuring plate 306 and the platform 1. The difference between the two measurements can then be used to determine the center distance between the two holes. When the center rod 305 rotates, because the inner diameter of the collar 309 is larger than the outer diameter of the center rod 305, the collar 309 will not obstruct the rotation of the center rod 305. Therefore, during use, the fishing reel can be automatically adjusted so that the holes on both sides are level with the platform 1, facilitating the measurement of the center distance between the holes. When fixing the fishing reel, first place the mounting base of the fishing reel in the limit card 9. Then, the fishing reel is inserted into the clamping assembly 18, and the fishing reel is pushed so that the limiting card 9 restricts the mounting part of the fishing reel under the action of the limiting spring 8, preventing the fishing reel from rotating freely on the clamping assembly 18. Then, the push rod 15 can drive the support plate 12 to move below the crossbeam 14, thereby driving the longitudinal base 301 to move above the table surface 1 through the limiting rod 11, moving another hole to another clamping assembly 18. The protrusion 17 can restrict the support plate 12 through the slide rail 16 to prevent the support plate 12 from tilting. Then, the push rod 6 can drive the transverse base 301 to approach the fishing reel and move the upper part of the base 301 closer to the fishing reel. The clamping assembly 18 is inserted into another hole of the fishing reel. During insertion, the clamping assembly 18 squeezes the fishing reel, causing the base 301 to stretch or compress the support spring 13, ensuring that the clamping assembly 18 can be fully inserted. During insertion, the limiting rod 11 can restrict the base 301 through the limiting groove 10. At the same time, the clamping assembly 18 can drive the center rod 305 to rotate according to the inclination of the hole at this time. The slider 5 can restrict the base 301 through the sliding groove 4 to prevent it from tilting during movement. In summary, during use, the entire fishing reel can be automatically clamped, which is convenient for subsequent adjustment.

[0031] Please see Figures 1 to 3 and Figures 6 to 7A clamping assembly 18 is provided at the end of the center rod 305 away from the measuring plate 306. The clamping assembly 18 includes a support rod 1801 and a through groove 1802. The support rod 1801 is connected to the end of the center rod 305 away from the measuring plate 306, and the surface of the support rod 1801 is provided with two through grooves 1802. The through directions of the through grooves 1802 are perpendicular to each other on the support rod 1801. The clamping assembly 18 also includes an adjusting spring 1803, a top plate 1804, a connecting rod 1805, and a limiting block 1806. Adjusting springs 1803, a top plate 1804, a connecting rod 1805, and a limiting block 1806 are symmetrically connected to the support rod 1801. The spring 1803 is adjusted, and the other end of the spring 1803 is connected to the top plate 1804. The connecting rod 1805 is rotatably connected in the through groove 1802, and the two ends of the connecting rod 1805 are rotatably connected to the limiting blocks 1806. The clamping assembly 18 also includes a guide plate 1807 and a limiting strip 1808. The end of the top plate 1804 away from the center rod 305 is rotatably connected to the guide plate 1807, and the side of the top plate 1804 near the support rod 1801 is symmetrically connected to the limiting strip 1808. The limiting block 1806 is engaged and slidably connected to the top plate 1804 through the limiting strip 1808.

[0032] The specific operation is as follows: When the clamping assembly 18 is inserted into the hole, after the edge of the hole contacts the guide plate 1807, pressure can be applied to the guide plate 1807, causing the guide plate 1807 to rotate on the top plate 1804 and move the top plate 1804 closer to the support rod 1801. This compresses the adjusting spring 1803, making the distance between the center lines of the top plate 1804 and the support rod 1801 equal to the inner diameter of the hole. When the top plate 1804 moves, it can drive the limiting block 1806 to slide inside the limiting strip 1808 and drive the connecting rod 1805 to rotate in the through groove 1802, thereby making the relative top plates 1804 move synchronously and maintaining the stability of the top plate 1804. All top plates 1804 can be pressed against the inner wall of the hole by the adjusting spring 1803, thereby clamping the fishing reel through the hole. During clamping, the center lines of the hole, support rod 1801, and center rod 305 can be aligned, which facilitates subsequent adjustment and measurement. By adjusting the setting of the spring 1803, the clamping assembly 18 can clamp fishing reels of different specifications, improving the applicability of the device. After the test is completed, as the base 301 resets, the clamping assembly 18 can be pulled out of the hole without obstructing the unloading of the fishing reel. In summary, during use, fishing reels of different specifications can be clamped and the clamping stability can be maintained.

[0033] In summary, when using this center distance measuring device for fishing tackle components, firstly, the mounting base of the fishing reel is placed between the limiting clips 9, and the main shaft mounting hole of the fishing reel is inserted into the clamping assembly 18. Then, the fishing reel is pushed so that the limiting clips 9, under the action of the limiting spring 8, restrict the mounting base of the fishing reel, preventing the fishing reel from rotating freely on the clamping assembly 18. Then, the push rod 15 can drive the support plate 12 to move below the crossbeam 14, thereby driving the longitudinal base 301 to move above the platform 1 through the limiting rod 11, moving the crank mounting hole of the fishing reel towards another clamping assembly 18. The protrusion 17 can restrict the support plate 12 through the slide rail 16 to prevent the support plate 12 from tilting. Then, the push rod 6 can drive the transverse base 301 closer to the platform 1. The fishing reel is inserted into another hole of the reel by its clamping assembly 18. During insertion, the clamping assembly 18 compresses the reel, causing the base 301 to stretch or compress the support spring 13, ensuring that the clamping assembly 18 can be fully inserted. During insertion, the limiting rod 11 can restrict the base 301 through the limiting groove 10. At the same time, the clamping assembly 18 can drive the center rod 305 to rotate according to the inclination of the hole. The slider 5 can restrict the base 301 through the sliding groove 4 to prevent it from tilting during movement. When the clamping assembly 18 passes through the hole, after the edge of the hole contacts the guide plate 1807, it can apply pressure to the guide plate 1807, thereby causing the guide plate 1807 to rotate on the top plate 1804 and causing the top plate to rotate. When the top plate 1804 moves closer to the support rod 1801, it compresses the adjusting spring 1803, making the distance between the center lines of the top plate 1804 and the support rod 1801 equal to the inner diameter of the hole. As the top plate 1804 moves, it drives the limiting block 1806 to slide inside the limiting strip 1808, and drives the connecting rod 1805 to rotate within the through groove 1802. This allows the relative top plates 1804 to move synchronously and maintain their stability, ensuring that all top plates 1804 are pressed against the inner wall of the hole under the action of the adjusting spring 1803. This clamps the fishing reel through the hole, and during clamping, the center lines of the hole, support rod 1801, and center rod 305 are aligned, facilitating subsequent adjustment and measurement. The adjustment spring 1803 is adjusted accordingly. This allows the clamping assembly 18 to clamp fishing reels of different specifications, improving the applicability of the device. After the test is completed, as the base 301 resets, the clamping assembly 18 can be pulled out of the hole without obstructing the unloading of the fishing reel. After the fishing reel is clamped, the lifting rod 310 on the base 301 can drive the collar 309 to move, thereby driving the central rod 305 to rotate on the support plate 303 through the connecting ring 304, adjusting the fishing reel. The transmitter on the horizontal mechanism 307 emits laser light to the reflector 302, and the receiver receives the light reflected back from the reflector 302. When the receiver can receive the light emitted by the corresponding transmitter, because the center line of the measuring plate 306 coincides with the center line of the central rod 305,This indicates that the center lines of the main shaft mounting holes and crank handle mounting holes of the fishing reel containing the two center rods 305 are parallel to the platform 1. Since the two measuring plates 306 are the same size, the rangefinder 308 detects the distance between the measuring plate 306 and the platform 1. The center distance between the two holes can be calculated by the difference between the two measurements (the distance between the measuring plate 306 and the platform 1 is the distance between the center line of each hole and the platform 1). When the center rod 305 is rotated, because the inner diameter of the collar 309 is larger than the outer diameter of the center rod 305, the collar 309 will not obstruct the rotation of the center rod 305.

[0034] The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and to design various embodiments with various modifications suitable for a particular purpose.
