Description

Technical Field

[0001] This application relates to the technical field of quality inspection of sanitary ware products, and particularly relates to a device for detecting the tensile and bending life of a shower pipe. Background Art

[0002] A shower pipe is a pipe used to connect a shower head and a water heater, usually made of flexible material to facilitate adjusting the position of the shower head during showering. During the manufacturing process of shower pipes, defective products may occur with a certain probability. Therefore, conducting life tests on shower pipes is a crucial step in the manufacturing process of shower pipe products.

[0003] Existing detection methods generally involve stretching at a low frequency for a period of time and then making a judgment on the life of the shower pipe. Such a detection method is obviously relatively simple and crude, unscientific and of low detection quality. Therefore, there is an urgent need for a life detection device suitable for shower pipes to improve the comprehensiveness of life detection of shower pipes. Summary of the Invention

[0004] To improve the comprehensiveness of life detection of shower pipes, this application provides a device for detecting the tensile and bending life of a shower pipe.

[0005] The device for detecting the tensile and bending life of a shower pipe provided by this application adopts the following technical solutions: A device for detecting the tensile and bending life of a shower pipe includes a detection machine table, a rotating pipe, and a winding rod. Among them, the rotating pipe is rotatably connected to the inner wall of the detection machine table, and a connecting head is provided on the peripheral wall of the rotating pipe; the winding rod is arranged inside the detection machine table, and a pulling rope is provided at the top of the winding rod; one end of the shower pipe is connected with a counterweight, and the other end is used to connect to the connecting head or the pulling rope. A rotating member for driving the rotating pipe to rotate and a pulling member for pulling the pulling rope are respectively provided inside the detection machine table.

[0006] By adopting the above technical solutions, when detecting the life of the shower pipe, one end of the shower pipe is connected to the counterweight, and the other end is connected to the pulling rope. The pulling member pulls the pulling rope a certain number of times, so as to conduct a tensile test on the shower pipe. One end of the shower pipe is connected to the counterweight, the other end is wound around the winding rod and then connected to the pulling rope. The pulling member pulls the pulling rope a certain number of times, so as to conduct a 360° bending test on the shower pipe. One end of the shower pipe is connected to the counterweight, and the other end is connected to the connecting head. The rotating member forces the rotating pipe to rotate, so that the connecting head rotates to a horizontal state, so as to conduct a 180° bending test on the shower pipe. The setting of the rotating pipe and the winding rod greatly improves the flexibility of the overall structure, so as to be able to conduct a comprehensive life detection on the shower pipe.

[0007] Optionally, a driving rod is rotatably installed in the inspection machine table. The winding rod includes a connecting section and a pushing section. One end of the connecting section is rotatably connected to the driving rod, and the other end is connected to the pushing section. First and second regions are respectively formed on both sides of the connecting section. Under normal conditions, the driving rod forces the length direction of the connecting section to rotate to a horizontal state, and the end of the pushing section away from the connecting section rotates to the first region, and the shower pipe is disposed through the first region. A flipping assembly is provided in the inspection machine table, and the flipping assembly is configured to force the winding rod to flip so that the shower pipe is wound around the outer peripheral side of the connecting section.

[0008] By adopting the above technical solution, the winding rod is composed of a connecting section and a pushing section. One end of the shower pipe is connected to a pulling rope, and the other end is connected to a counterweight. After the tensile test is completed, the flipping assembly forces the winding rod to flip. During the flipping process of the winding rod, the pushing section can drive the shower pipe to force the shower pipe to be wound around the outer peripheral side of the connecting section, so as to facilitate the 360° bending test of the shower pipe and improve the operation convenience of the overall structure.

[0009] Optionally, the flipping assembly includes a first mounting ring, a second mounting ring, a first rotating member, a second rotating member, and a third rotating member. The first mounting ring and the second mounting ring are both sleeved on the outer peripheral side of the driving rod and fixedly connected to the inner wall of the inspection machine table. The first mounting ring and the second mounting ring are spaced apart to form a swinging region. A rotating groove located in the swinging region is formed on the outer peripheral wall of the driving rod. The end of the connecting section away from the pushing section is disposed through the rotating groove and rotatably connected to the inner wall of the rotating groove. The first rotating member is disposed on the first mounting ring. When the length direction of the connecting section rotates from the horizontal state to the vertical state, the first rotating member forces the connecting section to rotate around its own central axis, so that the pushing section drives the shower pipe to flip to the second region. The second rotating member is disposed on the second mounting ring. When the length direction of the connecting section rotates from the vertical state back to the horizontal state, the second rotating member forces the connecting section to continue to rotate around its own central axis, so that the pushing section drives the shower pipe to flip back to the first region. The third rotating member is disposed on the inspection machine table to drive the driving rod to rotate.

[0010] By adopting the above technical solution, during the tensile resistance test of the shower pipe, the flipping angle of the connecting section is controlled at this stage, so that the length direction of the connecting section rotates to the horizontal state, and the shower pipe is located in the first area of the connecting section. After the tensile resistance test of the shower pipe is completed, the driving rod is forced to rotate by the third rotating member, so that the driving rod drives the length direction of the connecting section to rotate to the vertical state. During this process, the first rotating member forces the connecting section to rotate around its own central axis, so that the pushing section can drive the shower pipe to flip to the second area. Then, the driving rod is forced to rotate in the reverse direction by the third rotating member, so that the driving rod drives the length direction of the connecting section to rotate back to the horizontal state again. During this process, the second rotating member forces the connecting section to continue to rotate around its own central axis, so that the pushing section can drive the shower pipe to flip back to the first area again. The achieved effect is that by performing one "forward rotation" and "reverse rotation" of the driving rod, the shower pipe after the tensile resistance test can be wound around the outer peripheral side of the connecting section, so as to facilitate the 360° bending test, greatly improving the operation convenience of the overall structure and the detection efficiency of the shower pipe.

[0011] Optionally, the first rotating member includes a first gear and a first toothed ring. The first gear is coaxially arranged on the outer peripheral wall of one end of the connecting section far from the pushing section, and the first toothed ring is arranged on the surface of the first mounting ring and is coaxially arranged with the driving rod. When the length direction of the connecting section rotates from the horizontal state to the vertical state, the first gear and the first toothed ring are meshed and driven, so that the pushing section drives the shower pipe to flip to the second area.

[0012] By adopting the above technical solution, during the process that the driving rod drives the connecting section to rotate from the horizontal state to the vertical state, the first gear and the first toothed ring are meshed and driven, so as to drive the connecting section to rotate around its own central axis, so that the pushing section rotates around the central axis of the connecting section to pull the shower pipe to the second area.

[0013] Optionally, the second rotating member includes a second gear and a second toothed ring. The second gear is coaxially arranged on the outer peripheral wall of one end of the connecting section far from the pushing section, and the second toothed ring is arranged on the surface of the second mounting ring and is coaxially arranged with the driving rod. When the length direction of the connecting section rotates from the vertical state back to the horizontal state again, the second gear and the second toothed ring are meshed and driven, so that the pushing section drives the shower pipe to flip back to the first area again.

[0014] By adopting the above technical solution, after the pushing section pulls the shower pipe to the second area, the driving rod is driven to rotate in the reverse direction, driving the connecting section to rotate from the vertical state back to the horizontal state again. During this process, the second gear and the second toothed ring are meshed and driven, so as to drive the connecting section to continue to rotate around its own central axis, so that the pushing section continues to rotate around the central axis of the connecting section to redirect the shower pipe to the first area, realizing winding the shower pipe around the outer peripheral side of the connecting section and improving the operation convenience of the overall structure.

[0015] Optionally, a first docking member is provided between the first gear and the connecting section, and a second docking member is provided between the second gear and the connecting section; when the length direction of the connecting section rotates from a horizontal state to a vertical state, the first docking member forces circumferential linkage between the first gear and the connecting section, and the second docking member forces disconnection between the second gear and the connecting section; when the length direction of the connecting section rotates from a vertical state back to a horizontal state, the second docking member forces circumferential linkage between the second gear and the connecting section, and the first docking member forces disconnection between the first gear and the connecting section.

[0016] By adopting the above technical solution, the arrangement of the first docking member and the second docking member enables circumferential linkage between the first gear and the connecting section when the length direction of the connecting section rotates from a horizontal state to a vertical state, that is, the first gear ring can drive the connecting section to rotate through the first gear. In this state, the second docking member forces disconnection between the second gear and the connecting section, that is, the second gear ring cannot drive the connecting section to rotate through the second gear in this state. When the length direction of the connecting section rotates from a vertical state to a horizontal state, circumferential linkage occurs between the second gear and the connecting section, that is, the second gear ring can drive the connecting section to rotate through the second gear. In this state, the first docking member forces disconnection between the first gear and the connecting section, that is, the first gear ring cannot drive the connecting section to rotate through the first gear in this state. Such a design enables the overall structure to operate smoothly and reduces the possibility of interference between the first gear ring and the second gear ring.

[0017] Optionally, the third rotating member is a driving motor, the driving motor is arranged on the detection machine table, and the output shaft of the driving motor is coaxially connected to the driving rod; the driving motor is a servo motor.

[0018] By adopting the above technical solution, the driving motor is set as a servo motor to enable the driving rod to perform "forward rotation" and "reverse rotation".

[0019] Optionally, the length direction of the connecting section is perpendicularly arranged to the length direction of the pushing section, and there is an arc section between the connecting section and the pushing section. One end of the arc section is connected to the connecting section, and the other end is connected to the pushing section.

[0020] By adopting the above technical solution, the arrangement of the arc section enables arc transition between the connecting section and the pushing section, so that when the connecting section rotates from a vertical state back to a horizontal state, the pushing section can smoothly redirect the shower pipe back to the first area and wind the shower pipe around the outer peripheral side of the connecting section.

[0021] Optionally, a support bar is provided inside the detection machine table, and the top wall of the support bar forms a support surface for supporting the connecting section.

[0022] By adopting the above technical solution, after the shower pipe is wound around the outer peripheral side of the connecting section, the connecting section is lapped on the supporting surface of the supporting strip, reducing the possibility of deformation of the connecting section under the pressing of the counterweight of the shower pipe and improving the stability of the overall structure.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the setting of the rotating pipe and the winding rod, when detecting the service life of the shower pipe, one end of the shower pipe is connected to the counterweight, and the other end is connected to the pulling rope. By pulling the pulling rope a certain number of times through the pulling member, the tensile rope test of the shower pipe can be carried out. One end of the shower pipe is connected to the counterweight, and the other end is wound around the winding rod and then connected to the pulling rope. By pulling the pulling rope a certain number of times through the pulling member, the 360° bending test of the shower pipe can be carried out. One end of the shower pipe is connected to the counterweight, and the other end is connected to the connecting head. By forcing the rotating pipe to rotate through the rotating member, the connecting head is rotated to the horizontal state, so that the 180° bending test of the shower pipe can be carried out. The setting of the rotating pipe and the winding rod greatly improves the flexibility of the overall structure, so as to be able to comprehensively detect the service life of the shower pipe; 2. Through the setting of the flipping assembly, when the shower pipe is subjected to the tensile test, the flipping angle of the connecting section is controlled at this stage, so that the length direction of the connecting section is rotated to the horizontal state, and the shower pipe is located in the first area of the connecting section. After the tensile test of the shower pipe is completed, the driving rod is forced to rotate through the third rotating member, so that the driving rod drives the length direction of the connecting section to rotate to the vertical state. During this process, the first rotating member forces the connecting section to rotate around its own central axis, so that the pushing section can drive the shower pipe to flip to the second area. Then, the driving rod is forced to rotate in the reverse direction through the third rotating member, so that the driving rod drives the length direction of the connecting section to rotate to the horizontal state again. During this process, the second rotating member forces the connecting section to continue to rotate around its own central axis, so that the pushing section can drive the shower pipe to flip back to the first area again. The achieved effect is that by performing one "forward rotation" and "reverse rotation" of the driving rod, the shower pipe after the tensile test can be wound around the outer peripheral side of the connecting section, facilitating the 360° bending test, greatly improving the operation convenience of the overall structure and the detection efficiency of the shower pipe; 3. Through the setting of the arc section, the arc transition between the connecting section and the pushing section is realized, so that when the connecting section rotates from the vertical state to the horizontal state again, the pushing section can smoothly guide the shower pipe back to the first area, and the shower pipe is wound around the outer peripheral side of the connecting section.

Detailed implementation manners

[0026] The following Figures 1 - 10 further elaborates on this application in detail.

[0027] Example 1: The embodiment of this application discloses a shower pipe stretching and turning life detection device.

[0028] Referring to Figure 1 , Figure 2, A shower pipe stretching and turning life detection device, including a detection machine table 1, a rotating pipe 2 and a winding rod 3. Among them, the rotating pipe 2 is horizontally arranged, and both ends of the rotating pipe 2 are rotatably installed on the inner wall of the detection machine table 1. A connector 21 is fixedly installed on the peripheral wall of the rotating pipe 2; the connector 21 is used for the threaded connection of one end of the shower pipe 8; one end of the rotating pipe 2 is connected to a delivery pipe (not shown in the figure), and the delivery pipe is used to introduce air or water into the shower pipe 8.

[0029] A rotating member is arranged in the detection machine table 1, and the rotating member is used to drive the rotating pipe 2 to rotate around its own central axis. In this embodiment, the rotating member is set as a rotating motor 12, and the rotating motor 12 is fixedly installed on the inner wall of the detection machine table 1, and the output shaft of the rotating motor 12 is coaxially connected to the rotating pipe 2.

[0030] Refer to Figure 1 , The winding rod 3 is horizontally arranged, and both ends of the winding rod 3 are fixedly installed on the inner wall of the detection machine table 1; a reversing wheel 13 is rotatably installed on the top of the detection machine table 1, a pulling rope 4 is wound around the outer peripheral side of the reversing wheel 13, one end of the pulling rope 4 is used to connect with the shower pipe 8, and a counterweight 5 is connected to the lower end of the shower pipe 8.

[0031] A pulling member for pulling the pulling rope 4 is arranged in the detection machine table 1. In this embodiment, the pulling member is set as a cylinder 14, the cylinder body of the cylinder 14 is fixedly installed on the bottom wall of the detection machine table 1, and the piston rod of the cylinder 14 is fixedly connected to the pulling rope 4.

[0032] Refer to Figure 3 , Figure 4 , When the shower pipe 8 is subjected to a tensile test, one end of the shower pipe 8 is connected to the counterweight 5, and the other end is connected to the pulling rope 4. The pulling rope 4 is pulled a certain number of times by the cylinder 14 to conduct a tensile test on the shower pipe 8 with respect to the pulling rope 4. When the shower pipe 8 is subjected to a 360° bending test, one end of the shower pipe 8 is connected to the counterweight 5, and after the other end is wound around the outer peripheral wall of the winding rod 3, it is connected to the pulling rope 4. The pulling rope 4 is pulled a certain number of times by the cylinder 14 to conduct a 360° bending test on the shower pipe 8.

[0033] Refer to Figure 2 , Figure 5 , When the shower pipe 8 is subjected to a 180° bending test, one end of the shower pipe 8 is connected to the counterweight 5, and the other end is connected to the connector 21. The rotating pipe 2 is forced to rotate so that the connector 21 rotates to a horizontal state to conduct a 180° bending test on the shower pipe 8.

[0034] It should be noted that in the specific operation of the 180° bending test in this embodiment, first, the connector 21 is rotated towards the side of the rotating pipe 2 to make the connector 21 rotate to the horizontal state. A certain air pressure is flushed into the shower pipe 8 through the rotating pipe 2 (the end of the shower pipe 8 close to the counterweight 5 needs to be blocked). Then, the rotating pipe 2 is forced to rotate 180° around its own central axis to make the connector 21 rotate to the other side of the rotating pipe 2, and rotate 180° at a frequency of 20 times / min for 5000 times. After the above operations, room temperature water with a certain pressure is introduced into the shower pipe 8 through the delivery pipe, and whether there are any bad phenomena such as rupture, damage, and leakage in each part of the shower pipe 8 is observed.

[0035] The implementation principle of Embodiment 1 of this application is as follows: When detecting the service life of the shower pipe 8, one end of the shower pipe 8 is connected to the counterweight 5, and the other end is connected to the pulling rope 4. By pulling the pulling rope 4 a certain number of times, the shower pipe 8 can be tested for tensile strength against the pulling rope 4. One end of the shower pipe 8 is connected to the counterweight 5, and the other end is wound around the winding rod 3 and then connected to the pulling rope 4. By pulling the pulling rope 4 a certain number of times, the shower pipe 8 can be tested for 360° bending. One end of the shower pipe 8 is connected to the counterweight 5, and the other end is connected to the connector 21. By forcing the rotating pipe 2 to rotate through the rotating member, the connector 21 is rotated to the horizontal state, so that the shower pipe 8 can be tested for 180° bending. The settings of the rotating pipe 2 and the winding rod 3 greatly improve the flexibility of the overall structure, so as to be able to conduct a comprehensive service life detection on the shower pipe 8.

[0036] Embodiment 2: This application embodiment discloses a device for detecting the tensile and turning service life of a shower pipe.

[0037] The difference between the device for detecting the tensile and turning service life of a shower pipe disclosed in this application embodiment and Embodiment 1 lies in: Referring to Figure 6 、 Figure 7 In this embodiment, a driving rod 6 is installed in the testing machine table 1. The driving rod 6 is horizontally arranged, and both ends of the driving rod 6 are rotatably installed on the inner wall of the testing machine table 1. The winding rod 3 includes a connecting section 31 and a pushing section 32. The length direction of the connecting section 31 is perpendicular to the length direction of the pushing section 32. There is an arc section 33 between the connecting section 31 and the pushing section 32. One end of the arc section 33 is connected to the connecting section 31, and the other end is connected to the pushing section 32. The connecting section 31, the arc section 33, and the pushing section 32 are integrally formed to form the winding rod 3 in combination.

[0038] Referring to Figure 7 、 Figure 8, a rotating groove 61 is formed on the outer peripheral wall of the driving rod 6. One end of the connecting section 31 away from the pushing section 32 passes through the rotating groove 61 and is rotatably connected to the inner wall of the rotating groove 61 (i.e., the connecting section 31 can rotate around its own central axis). For the convenience of description, the two sides of the connecting section 31 are respectively defined as a first area 311 and a second area 312 below. Under normal conditions, the driving rod 6 forces the length direction of the connecting section 31 to rotate to the horizontal state, and the end of the pushing section 32 away from the connecting section 31 rotates to the first area 311. One end of the shower pipe 8 is connected to the pull rope 4, and the other end passes through the first area 311 and is connected to the counterweight 5.

[0039] A flipping assembly 7 is arranged in the detection machine table 1. The flipping assembly 7 is used to force the winding rod 3 to flip, so that the shower pipe 8 is wound around the outer peripheral side of the connecting section 31. The flipping assembly 7 includes a first mounting ring 71, a second mounting ring 72, a first rotating member, a second rotating member and a third rotating member. Both the first mounting ring 71 and the second mounting ring 72 are sleeved on the outer peripheral side of the driving rod 6 and are fixedly connected to the inner wall of the detection machine table 1. The first mounting ring 71 and the second mounting ring 72 are arranged at intervals to form a swinging area, and the rotating groove 61 is located in the swinging area.

[0040] Referring to Figure 6 , Figure 7 , Figure 8 , the first rotating member is arranged on the first mounting ring 71. When the length direction of the connecting section 31 rotates from the horizontal state to the vertical state, the first rotating member forces the connecting section 31 to rotate around its own central axis, so that the pushing section 32 drives the shower pipe 8 to flip to the second area 312. In this embodiment, the first rotating member includes a first gear 73 and a first toothed ring 74. The first gear 73 is coaxially arranged on the outer peripheral wall of one end of the connecting section 31 away from the pushing section 32. The first toothed ring 74 is fixedly installed on the surface of the first mounting ring 71 and is coaxially arranged with the driving rod 6. When the length direction of the connecting section 31 rotates from the horizontal state to the vertical state, the first gear 73 and the first toothed ring 74 are meshed and transmitted, so that the pushing section 32 drives the shower pipe 8 to flip to the second area 312.

[0041] The second rotating member is arranged on the second mounting ring 72. When the length direction of the connecting section 31 is rotated from the vertical state to the horizontal state again, the second rotating member forces the connecting section 31 to continue rotating around its own central axis, so that the pushing section 32 drives the shower pipe 8 to flip back to the first area 311 again. In this embodiment, the second rotating member includes a second gear 75 and a second toothed ring 76. The second gear 75 is coaxially arranged on the outer peripheral wall of one end of the connecting section 31 far away from the pushing section 32. The first gear 73 and the second gear 75 are arranged at intervals along the length direction of the connecting section 31. The second toothed ring 76 is fixedly installed on the surface of the second mounting ring 72 and is coaxially arranged with the driving rod 6. When the length direction of the connecting section 31 is rotated from the vertical state to the horizontal state again, the second gear 75 and the second toothed ring 76 are meshed and driven, so that the pushing section 32 drives the shower pipe 8 to flip back to the first area 311 again.

[0042] Refer to Figure 8 , Figure 9 , a first docking member is arranged between the first gear 73 and the connecting section 31, and a second docking member is arranged between the second gear 75 and the connecting section 31; when the length direction of the connecting section 31 is rotated from the horizontal state to the vertical state, the first docking member forces the first gear 73 and the connecting section 31 to be circumferentially linked (that is, when the first gear 73 rotates, the connecting section 31 rotates synchronously), and the second docking member forces the second gear 75 and the connecting section 31 to be disconnected (that is, when the second gear 75 rotates, it cannot drive the connecting section 31 to rotate synchronously).

[0043] When the length direction of the connecting section 31 is rotated from the vertical state to the horizontal state again, the second docking member forces the second gear 75 and the connecting section 31 to be circumferentially linked, and the first docking member forces the first gear 73 and the connecting section 31 to be disconnected.

[0044] Refer to Figure 9 , Figure 10 , the structures of the first docking member and the second docking member are the same. The structure of the first docking member is described below as an example, and the structure of the second docking member can be obtained in the same way. The first docking member includes a docking block 78 and a docking spring 781. Installation sleeves 79 are fixedly installed on the inner peripheral walls of the first gear 73 and the second gear 75. A plurality of first docking grooves 791 are formed in the inner wall of the installation sleeve 79. A plurality of docking blocks 78 are provided and are correspondingly arranged with the plurality of first docking grooves 791. Each docking block 78 is slidably installed in the corresponding first docking groove 791.

[0045] A plurality of second docking grooves 313 are formed in the outer peripheral wall of the connecting section 31, and the plurality of second docking grooves 313 are arranged at intervals around the central axis of the connecting section 31; the docking spring 781 is installed in the first docking groove 791, one end of the docking spring 781 is fixedly connected to the inner wall of the first docking groove 791, and the other end is fixedly connected to the docking block 78. Under normal conditions, the docking spring 781 forces the docking block 78 to extend out of the first docking groove 791 and be inserted into the second docking groove 313 of the connecting section 31. When the length direction of the connecting section 31 rotates from the horizontal state to the vertical state, the first gear 73 and the first toothed ring 74 are engaged, and the first gear 73 drives the connecting section 31 to rotate synchronously through the docking block 78 of the mounting sleeve 79. When the length direction of the connecting section 31 rotates from the vertical state to the horizontal state, the first gear 73 and the second gear 75 are reversely engaged, and the docking block 78 moves into the first docking groove 791 under the block of the connecting section 31, so that the connection between the first gear 73 and the connecting section 31 is disengaged.

[0046] It should be noted that in other embodiments, the first docking member and the second docking member can also be set in the form of a ratchet and a ratchet pawl to control the one-way rotation; the first gear 73 and the second gear 75 can be made of bevel gears, and the first toothed ring 74 and the second toothed ring 76 can be made of bevel toothed rings.

[0047] Referring to Figure 6 , the third rotating member is arranged on the detection machine table 1 to drive the driving rod 6 to rotate. The third rotating member is set as a driving motor 77, and the driving motor 77 is fixedly installed on the inner wall of the detection machine table 1. The output shaft of the driving motor 77 is coaxially connected to the driving rod 6; in this embodiment, the driving motor 77 is a servo motor.

[0048] A support bar 11 is fixedly installed on the inner wall of the detection machine table 1, and the top wall of the support bar 11 forms a support surface 111 for supporting the connecting section 31. When the length direction of the connecting section 31 rotates to the horizontal state, the connecting section 31 abuts against the support surface 111.

[0049] The implementation principle of Embodiment 2 of this application is as follows: When the shower pipe 8 is subjected to a tensile resistance test, the flipping angle of the connecting section 31 is controlled at this stage, so that the length direction of the connecting section 31 rotates to the horizontal state, and the shower pipe 8 is located in the first area 311 of the connecting section 31. After the shower pipe 8 finishes the tensile resistance test, the driving rod 6 is forced to "rotate forward", so that the driving rod 6 drives the length direction of the connecting section 31 to rotate to the vertical state. During this process, the first gear 73 and the first toothed ring 74 are engaged, forcing the connecting section 31 to rotate around its own central axis, so that the pushing section 32 can drive the shower pipe 8 to flip to the second area 312.

[0050] Next, force the drive rod 6 to perform a "reverse rotation", so that the drive rod 6 drives the length direction of the connecting section 31 to rotate back to the horizontal state again. During this process, the second gear 75 meshes with the second toothed ring 76, forcing the connecting section 31 to continue to rotate around its own central axis (when the drive rod 6 performs "forward rotation" and "reverse rotation", the rotation direction of the connecting section 31 is the same), so that the pushing section 32 can drive the shower pipe 8 to flip back to the first area 311 again.

[0051] The achieved effect is that by performing one "forward rotation" and "reverse rotation" on the drive rod 6, the shower pipe 8 after the anti-tensile test can be wound around the outer peripheral side of the connecting section 31, so as to facilitate the 360° bending test, greatly improving the operation convenience of the overall structure and the detection efficiency of the shower pipe 8.

[0052] The above is the preferred embodiment of the present application, and the protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
