Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of tensile testing equipment, specifically relating to a tensile testing device for composite material tubes. Background Technology
[0002] The composite material of the fishing rod is made of fiber-reinforced composites (FRC). This composite material consists of high-strength fibers and a resin matrix. The fibers are mainly responsible for bearing tensile force, while the resin matrix plays a role in protecting the fibers, transmitting shear force, and increasing the strength of the composite material.
[0003] Before leaving the factory, fishing rods need to undergo a series of performance tests. The fishing rod tensile test is one of the test items. The traditional tensile test is conducted manually. Currently, the most common method is to test with a heavy object. This is not only laborious, but also poses a great risk of the fishing rod breaking during the tensile test.
[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a tensile testing device for composite material tubes.
[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0030] like Figures 1 to 6 As shown, a tensile testing device for a composite material tube in one embodiment of the present invention includes: a first base 1 and a testing device 2.
[0031] like Figures 1 to 4 As shown, a pair of bases 104 are fixed on the first base 1, and a sliding rod 105 is fixed on each of the bases 104. The test device 2 is slidably mounted on the sliding rods 105, and the test device 2 slides on the sliding rods 105. A fixing plate 106 is fixed to one end of the pair of sliding rods 105 away from the base 104. The fixing plate 106 is used to fix one end of the pair of sliding rods 105 and also to mount the first fixing seat 108. A first base 1 is positioned between a pair of bases 104 and has a first fixed base 108 installed on it. A second fixed base 109 is installed on a fixed plate 106. A first transmission wheel 110 and a second transmission wheel 111 are respectively installed on the first fixed base 108 and the second fixed base 109. A transmission rope 112 is installed on the first transmission wheel 110 and the second transmission wheel 111. A first drive device 113 is installed on the first fixed base 108. The first drive device 113 drives the first transmission wheel 110 to rotate. The first transmission wheel 110 drives the transmission rope 112 to move, so that the transmission rope 112 drives the testing device 2 to slide up and down on a pair of slide bars 105. The second transmission wheel 111 is used to assist the transmission rope 112 in moving.
[0032] like Figures 1 to 4 As shown, a protective plate 107 is installed on one side of the first base 1. The protective plate 107 is used to protect the personal safety of the operator and prevent the test composite material tube from being ejected and hitting the operator after it breaks. A second base 101 is provided on one side of the first base 1. A pair of slide rails 102 are fixed on the second base 101. The tracks of the pair of slide rails 102 are respectively on the same horizontal plane as a pair of placement holes 207 to ensure the accuracy of tensile testing. The slide rails 102 are used to slide the tensile tester 103. The tensile tester 103 is slidably mounted on each of the pair of slide rails 102. The tensile tester 103 is used to record the tensile force of the test and transmit the recorded data to the control terminal.
[0033] like Figure 1 and 6 As shown, the testing device 2 is mounted on a pair of sliding rods 105. The testing device 2 includes two pairs of sliders 201, which slide on the pair of sliding rods 105 respectively. A fixed frame 202 is fixed between the two pairs of sliders 201. The fixed frame 202 is connected to both ends of the transmission rope 112. A fixed bracket 203 is installed inside the fixed frame 202. The transmission rope 112 drives the fixed frame 202 to move up and down. The fixed bracket 203 is fixed inside the fixed frame 202. A rotating shaft 204 is installed on the fixed bracket 203. The fixed bracket 203 provides support and fixation. A second driving device 216 is installed on the side of the fixed bracket 203 away from the first support arm 205. The second driving device 216 drives the rotating shaft 204 to rotate, causing the rotating shaft 204 to drive the first support arm 205 to rotate.
[0034] like Figures 5 to 6 As shown, a first support arm 205 is mounted on one end of the rotating shaft 204 outside the fixed frame 202. A pair of second support arms 206 are fixed on the first support arm 205. The first support arm 205 is used to drive the second support arms 206 to rotate. The composite material tube to be tested is placed on the second support arms 206. Each pair of second support arms 206 has a pair of placement holes 207. The composite material tube to be tested is inserted into the placement holes 207 and fixed, and then the testing is carried out.
[0035] like Figures 5 to 6 As shown, a pair of connecting plates 213 are fixed on the upper and lower side walls of the fixed frame 202. Each of the connecting plates 213 extends out of the fixed frame 202 and is equipped with a connecting rod 214. The connecting rod 214 is used to connect the connector 215 and the connecting plate 213. A connector 215 is fixed to one end of each of the connecting rods 214 near the transmission rope 112. The connectors 215 are fixedly connected to both ends of the transmission rope 112. Through the connectors 215 and the connecting rods 214, the two ends of the transmission rope 112 are connected to the upper and lower side walls of the fixed frame 202.
[0036] like Figures 5 to 6As shown, clamping bases 208 are fixed at placement holes 207 on the side wall of the second support arm 206. The clamping bases 208 assist in clamping the composite material tube to be tested. A pair of fixing plates 209 corresponding to the clamping bases 208 are fixed to the top of the second support arm 206. The fixing plates 209 are used to mount screws 210, and when the screws 210 are rotated, they move up and down. Screws 210 are threaded onto the fixing plates 209. Screws 210 drive clamping heads 212 to move towards the composite material tube being tested, clamping the composite material tube onto the second support arm 206. A clamping head 212 is fixed to the end of the screw 210 closest to the clamping bases 208, clamping the composite material tube. A knob handle 211 is fixed to the end of the screw 210 furthest from the clamping head 212, rotating the screw 210 to move it up and down.
[0037] Working principle: When using this equipment, first insert the tail end of the composite material tube to be tested into a pair of protective plates 107. Then, by turning the knob handle 211, the knob handle 211 drives the screw 210 to rotate. The screw 210 drives the clamping head 212 to clamp the composite material tube. After clamping, connect the other end to the tensile tester 103. Then, start the second drive device 216. The second drive device 216 drives the first support arm 205 to rotate via the rotating shaft 204. The first support arm 205 drives a pair of second support arms 206 to rotate as follows: Figure 1 The clockwise rotation shown in the diagram causes the composite material tube to rotate while simultaneously pulling the tensile tester 103 to slide on the slide rail 102, ensuring that the tensile force borne by the composite material tube is a vertically downward tensile force.
[0038] After rotating to the specified angle, the second drive device 216 is turned off, and then the first drive device 113 is started. The first drive device 113 drives the first transmission wheel 110 to rotate, the first transmission wheel 110 drives the transmission rope 112 to move, the transmission rope 112 drives the test device 2 to move upward, and the test device 2 drives the composite material tube to move upward, so that the product completes a certain bending strength test and then the tensile load test of the product is finally completed by lifting and lowering.
