Description

Technical Field

[0001] This utility model belongs to the field of cable testing technology, and specifically relates to a testing device. Background Technology

[0002] Cables are a general term encompassing optical fibers, electrical cables, and similar items. They serve multiple functions, including controlling and connecting equipment, and transmitting power, making them a common and indispensable part of daily life. During the manufacturing process, cables undergo one or more tests, such as bending resistance, high-temperature resistance, tensile strength, and bending resistance, depending on the intended use, to meet specific performance requirements.

[0003] Tensile testing of cables involves applying a certain tensile force to the cables and harnesses to check their strength and reliability under tension. However, existing cable tensile testing devices are complex in structure and cumbersome to operate, often requiring manual assistance during the testing process. Furthermore, existing cable tensile testing technologies do not allow for simultaneous bending testing, necessitating separate testing, which severely delays cable production efficiency.

[0004] Therefore, it is necessary to provide a testing device to address the aforementioned technical problems.

[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. Utility Model Content

[0006] The purpose of this invention is to provide a testing device that can solve the problems of complexity and low testing efficiency of existing cable tensile testing devices.

[0007] To achieve the above objectives, a specific embodiment of this utility model provides a testing device, including: a fixed base, a mid-section clamping mechanism, a rotary fixing mechanism, and a cable body;

[0008] The fixed base is provided with a sliding groove.

[0009] The mid-section clamping mechanism is mounted on the fixed base. The mid-section clamping mechanism includes a clamping base, on which a pair of adjustment grooves are cut. On the clamping base, a plurality of evenly distributed fixed protrusions are fixed. A rotating clamping arm is rotatably arranged in the adjustment grooves. On the rotating clamping arm, a plurality of evenly distributed clamping arm protrusions are installed.

[0010] The rotary fixing mechanism is installed on one side of the clamping base. The rotary fixing mechanism includes a rotating support plate, a fixing sleeve is fixed on the rotating support plate, and multiple fixing screws are threaded on the fixing sleeve. One end of each of the multiple fixing screws located inside the fixing sleeve is rotatably connected to a clamping piece. A support drive assembly is also installed on one side of the rotating support plate. A cable body is inserted between the fixing sleeve and the clamping base.

[0011] In one or more embodiments of this utility model, an electric push cylinder is installed in the fixed base to control the extension and retraction of the piston push rod. The piston push rod is installed on the electric push cylinder, and the other end of the piston push rod is inserted into the sliding groove. The piston push rod can push or pull the support frame, so that the support frame can move, thereby achieving the effect of stretching the cable body and realizing the function of stretching detection.

[0012] In one or more embodiments of this utility model, a lifting handle is fixed at the end of each pair of rotating clamping arms away from the clamping base for pulling the rotating clamping arms, which facilitates the operation of the staff.

[0013] In one or more embodiments of this utility model, a plurality of evenly distributed fixed racks are installed on the rotating clamping arm. The fixed racks mesh with the limiting racks, so that the rotating clamping arm cannot rotate, thereby making it less likely to reduce the fixing effect on the cable body during the tensile testing process.

[0014] Both ends of the rotating clamping arm are fixedly connected to the clamping base with support bearings to fix the rotating clamping arm, making it less likely to fall off and allowing it to rotate freely, which facilitates fixing the cable body.

[0015] In one or more embodiments of this utility model, a support column is inserted into the rotating clamping arm for fixing multiple limiting racks and driving multiple limiting racks to move. The support column is equipped with limiting racks that mesh with the fixing racks. By meshing the limiting racks with the fixing racks, the rotating clamping arm is less likely to rotate, thereby making it less likely for the rotating clamping arm to reduce its fixing effect on the cable body.

[0016] In one or more embodiments of this utility model, a square column is fixedly connected to the end of the support column away from the rotating clamping arm, making it difficult for the support column to rotate. As a result, when the limiting rack and the fixed rack mesh with each other, the rotating clamping arm is not easy to rotate. A pull-out handle is fixed on the square column for easy pulling and operation.

[0017] Multiple push springs are fixedly connected between the support column and the clamping base to push the support column. This allows the support column to drive multiple limiting racks to re-insert into the rotating clamping arm after the operator releases the pull handle. Consequently, the limiting racks and the fixed racks mesh with each other again, achieving the effect of fixing the rotating clamping arm.

[0018] In one or more embodiments of this utility model, a groove is cut into the clamping piece, and a fixed bearing is installed in the groove. The fixed bearing is disposed between the fixed screw and the clamping piece, so that the rotation of the fixed screw is not easy to drive the clamping piece, thereby facilitating the clamping piece to be pressed against the cable body to fix one end of the cable body.

[0019] In one or more embodiments of this utility model, the support drive assembly includes a support frame for supporting the drive motor and the auxiliary rotating ball, and has the function of driving them to move, thereby enabling the function of pulling the cable body. The lower end of the support frame is disposed in the sliding groove, and the end of the piston push rod away from the electric push cylinder is fixedly connected to the support frame.

[0020] The support frame is equipped with a drive motor to drive the transmission support shaft to rotate, providing power for the twisting cable body. The drive motor is fixedly connected to the rotating support disk by the transmission support shaft, which supports the rotating support disk and drives the rotating support disk to rotate.

[0021] In one or more embodiments of this utility model, a support tray is also fixed on the support frame, and a plurality of auxiliary rotating balls are installed on the support tray to assist in driving the rotating support disk to slide, and it is not easy to affect the rotation of the rotating support disk.

[0022] In one or more embodiments of this utility model, a plurality of fixed guide rods are inserted into the portion of the support frame disposed in the sliding groove, and a plurality of connecting springs are fixedly connected between the support frame and the fixed base to assist in pushing the support frame to reset.

[0023] Compared with the prior art, this utility model simplifies the complexity of the cable tensile testing device by setting up the corresponding mechanism, and enables tensile and bending tests to be performed simultaneously, thereby improving the testing efficiency of cables, and thus improving the production efficiency of cables, and increasing economic benefits for users.

Detailed Implementation

[0035] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. 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.

[0036] like Figures 1-8 As shown, a testing device in one embodiment of the present invention includes: a fixed base 1, a mid-section clamping mechanism 2, a rotary fixing mechanism 3, and a cable body 4.

[0037] like Figures 1-2 As shown, a sliding groove 101 is cut into the fixed base 1 to provide space for the sliding of the support frame 307. An electric push cylinder 102 is installed inside the fixed base 1 to control the extension and retraction of the piston rod 103. The piston rod 103 is installed on the electric push cylinder 102, and the other end of the piston rod 103 is inserted into the sliding groove 101. The piston rod 103 can push or pull the support frame 307, allowing the support frame 307 to move, thereby achieving the effect of stretching the cable body 4 and realizing the function of stretching detection.

[0038] like Figures 1-4 As shown, the mid-section clamping mechanism 2 is mounted on the fixed base 1. The mid-section clamping mechanism 2 includes a clamping base 201 for fixing the mid-section of the cable body 4. The clamping base 201 has a pair of adjustment grooves 202 to provide space for the rotation of the rotating clamping arm 204. Multiple evenly distributed fixing protrusions 203 are fixed on the clamping base 201 to improve the fixing effect on the cable body 4.

[0039] Specifically, a rotating clamping arm 204 is rotatably installed inside the adjusting groove 202 to fix the cable body 4 by rotation, so that the cable body 4 is not easy to slip during the tensile test. Multiple evenly distributed clamping arm protrusions 205 are installed on the rotating clamping arm 204 to improve the fixing effect on the cable body 4.

[0040] In addition, each of the two rotating clamping arms 204 has a lifting handle 206 fixed at the end away from the clamping base 201, which is used to pull the rotating clamping arm 204 to facilitate the operation of the staff.

[0041] like Figures 1-6As shown, multiple evenly distributed fixed racks 207 are installed on the rotating clamping arm 204. The fixed racks 207 mesh with the limiting racks 210, so that the rotating clamping arm 204 cannot rotate, thus making it less likely to reduce the fixing effect on the cable body 4 during the tensile test.

[0042] Both ends of the rotating clamping arm 204 are fixedly connected to the clamping base 201 with support bearings 208, which are used to fix the rotating clamping arm 204, making it difficult for the rotating clamping arm 204 to fall off, and allowing it to rotate freely, which is convenient for fixing the cable body 4.

[0043] like Figures 1-7 As shown, a support column 209 is inserted inside the rotating clamping arm 204 for fixing multiple limiting racks 210 and driving the multiple limiting racks 210 to move. The support column 209 is equipped with limiting racks 210 that mesh with the fixing racks 207. The meshing of the limiting racks 210 with the fixing racks 207 makes it difficult for the rotating clamping arm 204 to rotate further, thereby making it less likely for the rotating clamping arm 204 to reduce its fixing effect on the cable body 4.

[0044] like Figures 1-7 As shown, a square column 211 is fixedly connected to the end of the support column 209 away from the rotating clamping arm 204, making it difficult for the support column 209 to rotate. Consequently, when the limiting rack 210 and the fixed rack 207 mesh with each other, the rotating clamping arm 204 is less likely to rotate. A pull-out handle 212 is fixed on the square column 211 for easy pulling and operation.

[0045] like Figure 6 As shown, multiple push springs 213 are fixedly connected between the support column 209 and the clamping base 201 to push the support column 209. This allows the support column 209 to drive multiple limiting racks 210 to re-insert into the rotating clamping arm 204 after the operator releases the pull handle 212. This causes the limiting racks 210 and the fixed racks 207 to mesh with each other again, thus achieving the effect of fixing the rotating clamping arm 204.

[0046] like Figures 1-3As shown, the rotary fixing mechanism 3 is installed on one side of the clamping base 201. The rotary fixing mechanism 3 includes a rotating support plate 301, which supports and fixes the fixing sleeve 302 and drives its movement. The fixing sleeve 302 is fixed on the rotating support plate 301 for inserting one end of the cable body 4 for easy fixing. Multiple fixing screws 303 are threaded onto the fixing sleeve 302 for pushing the clamping piece 304. The clamping piece 304 is rotatably connected to one end of each of the multiple fixing screws 303 located inside the fixing sleeve 302. A support drive assembly is also installed on one side of the rotating support plate 301. The cable body 4 is inserted between the fixing sleeve 302 and the clamping base 201.

[0047] like Figures 1-8 As shown, a groove is cut into the clamping piece 304, and a fixed bearing is installed in the groove. The fixed bearing is located between the fixed screw 303 and the clamping piece 304, so that the rotation of the fixed screw 303 does not easily drive the clamping piece 304, thereby making it easier to press the clamping piece 304 against the cable body 4, so as to fix one end of the cable body 4.

[0048] like Figures 1-3 As shown, the support drive assembly includes a support frame 307, which supports the drive motor 308 and the auxiliary rotating ball 306, and has the function of driving them to move, thereby enabling the cable body 4 to be pulled. The lower end of the support frame 307 is provided in the sliding groove 101, and the end of the piston push rod 103 away from the electric push cylinder 102 is fixedly connected to the support frame 307.

[0049] Specifically, a drive motor 308 is installed on the support frame 307 to drive the transmission support shaft 309 to rotate, providing power for the twisted cable body 4. The drive motor 308 and the rotating support disk 301 are fixedly connected by the transmission support shaft 309, which is used to support the rotating support disk 301 and drive the rotating support disk 301 to rotate.

[0050] like Figures 1-8 As shown, a support tray 305 is also fixed on the support frame 307. Multiple auxiliary rotating balls 306 are installed on the support tray 305 to assist in sliding the rotating support disk 301 without significantly affecting its rotation. Several fixed guide rods 310 are inserted into the portion of the support frame 307 within the sliding groove 101. Several connecting springs 311 are fixedly connected between the support frame 307 and the fixed base 1 to assist in pushing the support frame 307 back to its original position.

[0051] In practical use, one end of the cable body 4 is inserted through the clamping base 201 into the fixing sleeve 302, and then the fixing screw 303 is rotated so that the clamping piece 304 can clamp the cable body 4, thereby fixing one end of the cable body 4. Then the cable body 4 is straightened.

[0052] Pull the pull handle 212 again, so that the square column 211 drives the support column 209 to move, so that the limiting rack 210 and the multiple fixed racks 207 no longer mesh with each other. At this time, rotate the rotating clamping arm 204 so that the rotating clamping arm 204 can clamp and fix the cable body 4. Then release the pull handle 212, so that the push spring 213 pushes the support column 209 to move, so that the limiting rack 210 meshes with the fixed racks 207 again, thereby achieving the effect of fixing the rotating clamping arm 204, making the rotating clamping arm 204 less likely to rotate, and thus less likely to reduce the fixing effect on the cable body 4.

[0053] Then, the electric push cylinder 102 is activated, and the piston push rod 103 pushes the support frame 307. The support frame 307 then drives the drive motor 308 and the auxiliary rotating ball 306 to move, thereby pulling the fixed end of the cable body 4. The electric push cylinder 102 can control the applied force. During the tensile test, the drive motor 308 can also be activated, and the drive support shaft 309 drives the rotating support disk 301, so that one end of the cable body 4 can rotate, thereby achieving the effect of detecting the torsion of the cable body 4.

[0054] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0055] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
