A tensile strength testing device for fishing line processing

Abstract

This utility model discloses a tensile force detection device for fishing line processing, belonging to the technical field of fishing line detection devices. It includes a base with a sliding guide mounted on one side, on which a line end clamp is slidably mounted. The line end clamp is fixedly mounted on the other side of the base. A tension hydraulic cylinder is fixedly mounted at the end of the base with the sliding guide and is connected to the adjacent line end clamp via a force-measuring connector. The key technical point is that a clamping cylinder drives a movable clamp downwards, bringing it close to the fixed clamp. The half-clamp installed between the two clamps then clamps and fixes the end of the fishing line placed within it. This clamping scheme is simple in structure, easy to operate, and greatly improves detection efficiency. When the tension hydraulic cylinder pulls the outer cylinder shell outwards, a ring-shaped pressure sensor is pressed against the outer cylinder shell, thereby detecting the tensile force applied by the tension hydraulic cylinder to the movable line end clamp through the reaction force, eliminating the need for manual reading of the tensile force.

Description

Technical Field

[0001] This utility model relates to the technical field of fishing line testing devices, specifically a tensile testing device for fishing line processing. Background Technology

[0002] Fishing line tensile strength testing is of great significance. In fishing, the fishing line is the crucial link between the angler and the fish, and its tensile strength directly affects the success or failure of the fishing. Through tensile strength testing, the maximum tensile strength that the fishing line can withstand can be accurately determined, helping anglers to scientifically select lines based on the size and strength of the target fish. If the fishing line's tensile strength is insufficient, it is prone to breaking and losing large fish; if the tensile strength is too high, it may affect the fishing line's flexibility and sensitivity. Furthermore, tensile strength testing can also verify the quality of the fishing line, ensuring that it meets production standards, providing reliable protection for anglers, and improving the fishing experience and catch rate.

[0003] Utility model CN220170746U discloses a fishing line tensile strength testing device, which includes a top cover and a device base. Base pads are fixedly connected to the four corners of the bottom of the device base. A clamping mechanism is provided on the top of the device base, comprising a fixing block, a first clamping block, a first rotating arm, a second rotating arm, and a second clamping block. The bottom of the fixing block is fixedly connected to the upper surface of the device base. This fishing line tensile strength testing device effectively solves the problem that vibration and shaking during actual use can cause the fishing line to slip out of the device, making it impossible to effectively obtain the tensile strength of the fishing line and resulting in low efficiency in fishing line tensile strength testing. During operation, the device can conveniently and securely clamp the fishing line to be tested within the device and prevent the fishing line from slipping out during operation, thereby improving the usability of the device.

[0004] When the above-mentioned device clamps and installs fishing line, the movable block can only move downwards, and the first clamping block is fixedly installed. However, two rotating arms are rotatably connected between the two. Therefore, the rotating arms restrict the displacement of the movable block during its up-and-down movement, making it impossible for the device to stably clamp and fix the fishing line. In addition, the device judges the tensile force that the fishing line can withstand by comparing it with a scale. This method is very prone to errors in reading, affecting the accuracy of detecting the tensile force limit that the fishing line can withstand. Therefore, in order to solve the above problems, a tensile force detection device for fishing line processing is proposed. Utility Model Content

[0005] To address the technical problems of fishing line detection devices in comparative technologies being unable to stably clamp and fix both ends of the line, and the methods for determining the tensile limit being prone to errors in reading, and not being simple and intuitive enough, this utility model provides a tensile force detection device for fishing line processing.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] A tensile testing device for fishing line processing includes a base with a sliding guide mounted on one side, wherein a line end clamp is slidably mounted on the sliding guide, and a line end clamp is fixedly mounted on the other side of the base; a tension hydraulic cylinder is fixedly disposed at the end of the base with the sliding guide, and is connected to the adjacent line end clamp via a force measuring connector; wherein the line end clamp includes a C-shaped frame, a fixed clamp is fixedly mounted on the bottom inner side, and a movable clamp is slidably mounted on the top inner side, both the fixed clamp and the movable clamp are provided with a semi-clamping cylinder, and a clamping cylinder for driving the movable clamp to move up and down is mounted on the top of the C-shaped frame.

[0008] In one possible implementation, the semi-clamping cylinder includes a rubber cylinder body with several clamping protrusions machined on its inner side, and an inlet is machined at the front end of the rubber cylinder body.

[0009] In one possible implementation, the fixed clamp includes a clamping plate one as the main body, and the movable clamp includes a clamping plate two as the main body. The clamping plate one and the clamping plate two have the same structure and are arranged in a mirror image. Guide rods are fixedly provided on both sides of the clamping plate one, and guide cylinders that are slidably connected to the guide rods are fixedly provided on both sides of the clamping plate two.

[0010] In one possible implementation, both clamping plate one and clamping plate two have grooves for mounting the half clamping cylinder, and the grooves have insertion slots. The half clamping cylinder is fixedly provided with an insertion shaft for insertion and connection with the insertion slot.

[0011] In one possible implementation, the bottom of the first clamping plate is fixedly provided with symmetrically arranged support columns, which are fixedly connected to the C-shaped frame, and the top of the second clamping plate is fixedly provided with symmetrically arranged sliding rods, which are slidably connected to the C-shaped frame.

[0012] In one possible implementation, the force measuring connector includes an outer cylindrical shell slidably connected to a connecting shaft, wherein the outer end of the connecting shaft is fixedly connected to a connecting disc for bolting to a wire end clamp, and the inner end of the connecting shaft is fixedly connected to a pusher plate slidably disposed in the outer cylindrical shell, wherein an annular pressure sensor is mounted on the pusher plate.

[0013] In one possible implementation, the sliding guide includes symmetrically arranged guide plates with grooves, and a connecting slide plate fixedly installed on both sides of the line end clamp, on which a sliding block is fixedly provided and slidably connected to the groove.

[0014] In summary, this utility model has the following beneficial technical effects:

[0015] By driving the movable clamp downward with the clamping cylinder to bring it close to the fixed clamp, the end of the fishing line placed in the half-clamp can be clamped and fixed by the half-clamp installed between the two. This clamping solution has a simple structure and is easy to operate, which can greatly improve the detection efficiency.

[0016] Since the main body of the semi-clamping tube is made of rubber and its inner side is machined with several clamping protrusions, this solution can effectively clamp the end of the fishing line while protecting the fishing line and preventing it from being clamped and broken. In addition, the front end of the semi-clamping tube has an inlet, which makes it easy to quickly insert the end of the fishing line into the semi-clamping tube when installing the fishing line.

[0017] In addition, by setting a force-measuring connector, which includes an outer cylinder shell and a connecting shaft, the two are slidably connected. When the tension hydraulic cylinder pulls the outer cylinder shell outward, the push plate at the end of the connecting shaft will push the annular pressure sensor, causing it to press against the outer cylinder shell. In this way, the tension applied by the tension hydraulic cylinder to the movable wire end clamp can be detected through the reaction force. There is no need to manually read the tension reading with a scale, which can significantly improve the accuracy of the test results. Attached Figure Description

[0025] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0026] like Figure 1 As shown, the tensile testing device for fishing line processing provided in this embodiment includes a base 1, on one side of which a sliding guide 11 is installed, wherein a line end clamp 2 is slidably installed on the sliding guide 11, and the line end clamp 2 is fixedly installed on the other side of the base 1; a tension hydraulic cylinder 3 is fixedly installed at one end of the base 1 where the sliding guide 11 is located, and is connected to the nearby line end clamp 2 through a force measuring connector 4.

[0027] Based on the above technical solution, when conducting tensile testing, the two ends of the fishing line are clamped and fixed by the line end clamp 2. Then, the tension hydraulic cylinder 3 pulls the line end clamp 2, which is connected to its transmission, to slide and apply tension to the fishing line, thereby conducting tensile testing. During this process, the force measuring connector 4 can monitor the tension applied by the tension hydraulic cylinder 3 in real time, thereby playing the role of testing its tensile performance.

[0028] Among them, such as Figure 2 - Figure 3 As shown, the line end clamp 2 includes a C-shaped frame 21, with a fixed clamp 22 fixedly installed on its inner bottom and a movable clamp 23 slidably installed on its inner top. Both the fixed clamp 22 and the movable clamp 23 are provided with a semi-clamping tube 24. In addition, a clamping cylinder 25 is installed on the top of the C-shaped frame 21 to drive the movable clamp 23 to move up and down. By driving the movable clamp 23 to move down through the clamping cylinder 25, it can be brought close to the fixed clamp 22. The fishing line end placed therein can be clamped and fixed by the semi-clamping tube 24 installed between the two. This clamping scheme has a simple structure and is easy to operate, which can greatly improve the detection efficiency.

[0029] In the above structure, the semi-clamping tube 24 includes a rubber tube body 241, on which a number of clamping protrusions 242 are formed. The front end of the rubber tube body 241 is formed with an inlet 243. Since the body of the semi-clamping tube 24 is made of rubber and a number of clamping protrusions 242 are formed on its inner side, this solution can effectively clamp the end of the fishing line while protecting the fishing line and preventing it from being broken. In addition, the inlet 243 is provided at the front end of the semi-clamping tube 24. This structure makes it easy to quickly insert the end of the fishing line into the semi-clamping tube 24 when installing the fishing line.

[0030] like Figure 3 As shown, the fixed clamp 22 includes a clamping plate 221 as the main body, and the movable clamp 23 includes a clamping plate 231 as the main body. The clamping plates 221 and 231 have the same structure and are arranged in a mirror image. The clamping plates 221 are fixedly provided with guide rods 223 on both sides, and the clamping plates 231 are fixedly provided with guide cylinders 233 that are slidably connected to the guide rods 223 on both sides. Through the slidable connection between the guide rods 223 and the guide cylinders 233, the clamping plates 231 can be kept parallel and aligned with the clamping plates 221 when they move closer to the clamping plates 221, thereby ensuring the clamping effect and preventing the clamping plates 231 from shifting during movement and affecting its clamping effect.

[0031] To enable the detachable installation of the set semi-clamp 24, such as Figure 3 As shown, both clamping plate 221 and clamping plate 231 have grooves for mounting the half clamping cylinder 24, and the grooves have insertion slots. The half clamping cylinder 24 is fixedly provided with an insertion shaft 244 for insertion and connection with the insertion slot. The above structure can realize the detachable installation of the half clamping cylinder 24 through the insertion connection between the insertion shaft 244 and the insertion slot, and can be easily replaced after wear.

[0032] In addition, to enable the installation of the movable clip 23 and the fixed clip 22, such as Figure 3 As shown, the bottom of the clamping plate 221 is fixedly provided with symmetrically arranged support columns 222, which are fixedly connected to the C-shaped frame 21. The clamping plate 221 can be supported and fixed by the support columns 222. The top of the clamping plate 231 is fixedly provided with symmetrically arranged sliding rods 232, which are slidably connected to the C-shaped frame 21. The sliding rods 232 can realize the sliding connection between the clamping plate 231 and the C-shaped frame 21, providing the necessary structural foundation for the up and down sliding of the clamping plate 231.

[0033] like Figure 5As shown, the force measuring connector 4 includes an outer cylinder shell 41, which is slidably connected to a connecting shaft 42. The outer end of the connecting shaft 42 is fixedly connected to a connecting plate 43 for bolting to the wire end clamp 2, and the inner end of the connecting shaft 42 is fixedly connected to a push plate 44 slidably disposed in the outer cylinder shell 41. An annular pressure sensor 45 is installed on the push plate 44. When the tension hydraulic cylinder 3 pulls the outer cylinder shell 41 outward, the push plate 44 at the end of the connecting shaft 42 will push the annular pressure sensor 45, causing it to press against the outer cylinder shell 41. In this way, the tension applied by the tension hydraulic cylinder 3 to the movable wire end clamp 2 can be detected by the reaction force. There is no need to manually read the tension reading with a scale, which can significantly improve the accuracy of the detection results.

[0034] like Figure 4 As shown, the sliding guide frame 11 includes symmetrically arranged guide plates 111 with grooves on them, and also includes connecting slide plates 112 fixedly installed on both sides of the line end clamp 2, with sliding blocks 113 fixedly installed on them and slidably connected to the grooves. Based on the above structural scheme, the line end clamp 2 is slidably connected to the guide plates 111 through the connecting slide plates 112, so that it can slide within a certain range to complete the stretching of the fishing line.

[0035] The working principle and usage process of this utility model:

[0036] During the tensile test, the two ends of the fishing line are clamped and fixed by the line end clamp 2. Then, the tension hydraulic cylinder 3 pulls the line end clamp 2, which is connected to its transmission, to apply tension to the fishing line. During this process, the force measuring connector 4 can monitor the tension applied by the tension hydraulic cylinder 3 in real time, thereby playing a role in testing its tensile performance. When installing the fishing line, the clamping cylinder 25 drives the movable clamp 23 to move down and bring it close to the fixed clamp 22. The half clamp 24 installed between the two can then clamp and fix the end of the fishing line placed therein. This clamping scheme is simple in structure, easy to operate, and can greatly improve the testing efficiency.

[0037] During the stretching process, when the stretching hydraulic cylinder 3 pulls the outer cylinder shell 41 outward, the push plate 44 at the end of the connecting shaft 42 will push the annular pressure sensor 45, causing it to press against the outer cylinder shell 41. In this way, the tension applied by the stretching hydraulic cylinder 3 to the movable wire end clamp 2 can be detected through the reaction force. There is no need to manually read the tension reading with a ruler, which can significantly improve the accuracy of the detection results.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
