[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] A cable oscillation wave testing device, such as Figures 1-4 As shown, the device includes a base 1, with casters attached to the four corners of the bottom of the base 1. A circular hole is formed in the center of the inner cavity of the base 1, and a connecting cylinder 2 is provided inside the circular hole. The side walls of the connecting cylinder 2 are connected to the inner wall of the circular hole near the bottom. A body 4 is provided at the top of the inner cavity of the connecting cylinder 2. A connection port is formed at the center of the top of the body 4, and a control panel is connected to the inner cavity of the connection port. Several cable sockets are formed on one side of the inner cavity of the control panel. A display screen is connected to the center of one side of the control panel, and several operation buttons are connected to the center of the control panel. Adjustment components 3 are provided on both sides of the body 4. The adjustment components 3 include a fixing frame 31 located at the center of one side of the bottom of the body 4, and the bottom side of the fixing frame 31 is connected to the center of one side of the top of the connecting cylinder 2.

[0031] When the operator wants to use the cable oscillation wave testing device to test the cable, they first power the main body 4. Then, the operator operates the control panel to power the drive motor 35, which moves the base 1 upward. As the base 1 moves upward, the four casters gradually separate from the ground, allowing the bottom of the main body 4 to quickly contact the ground. This allows the cable oscillation wave testing device to be placed stably on the ground for testing. Once the bottom of the main body 4 is in contact with the ground, the operator inserts the cable to be tested into the cable socket on the control panel. Then, the operator operates the control panel to start the main body 4 to perform the oscillation wave test on the cable. The test results are displayed on the control panel screen, allowing the operator to understand and record the test data. When the operator wants to remove the cable... When the oscillation wave testing device is moved to different locations in the work area, the operator operates the control panel to power the drive motor 35, which moves the base 1 downwards. This allows the base 1 to quickly move the four casters downwards to contact the ground in the work area, facilitating the operator's movement of the cable oscillation wave testing device to different locations in the work area. When the operator needs to load the cable oscillation wave testing device onto a vehicle for transport, the operator uses the two lifting rings 5 ​​to hoist the device onto the vehicle. If one of the lifting rings 5 ​​is damaged and needs to be replaced, the operator presses the two locking rods 8 into the insert plate 9, then rotates the connecting rod 6 to rotate the two locking rods 8 to a position where they are not on the same horizontal line as the adjacent locking holes. This allows the damaged lifting ring 5 to be removed from the body 4 for replacement.

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, there are fixed seats 7 connected to the center of both sides of the body 4. Each fixed seat 7 has a locking hole at the center of both sides, and the two fixed seats 7 are symmetrically arranged with the center of the inner cavity of the body 4 as the axis of symmetry.

[0033] When the staff removes the damaged insert plate 9 from the fixed base 7 or fixes the new insert plate 9 back into the fixed base 7, the purpose of replacing the hanging ring 5 can be achieved conveniently.

[0034] like Figure 1 , Figure 3 and Figure 4As shown, each of the two fixed seats 7 has a plate 9 inside. A connecting rod 6 is connected to the center of one side of each of the two plates 9, and a lifting ring 5 is connected to one end of each of the two connecting rods 6. Two guide rods 10 are connected to the center of the inner walls on both sides of each of the two plates 9. A guide plate 12 is sleeved on both guide rods 10 near both ends. A locking rod 8 is connected to the center of one side of each of the two guide plates 12. Through holes are opened at the center of both sides of each of the two plates 9. One end of each locking rod 8 on both sides passes through the inner cavity of the adjacent through hole and extends to the adjacent locking hole.

[0035] When a lifting ring 5 is damaged and needs to be replaced, the worker presses the two locking levers 8 into the insertion plate 9. Then, the worker rotates the connecting rod 6 to rotate the two locking levers 8 to a vertical position, thereby releasing the restriction on the insertion plate 9. This allows for easy removal and replacement of the damaged lifting ring 5 from the machine body 4, facilitating its practical use. After being disassembled, the worker places the new insert plate 9 into the fixed base 7. Then, the worker rotates the two locking rods 8 to the same horizontal position as the adjacent locking holes using the connecting rod 6. At this time, the two fixing springs 11 begin to extend outward after the external force is removed. This allows the two fixing springs 11 to drive the two guide plates 12 to move to both sides of the two adjacent guide rods 10. This allows the two guide plates 12 to push the two locking rods 8 into the adjacent locking holes, thus fixing the new insert plate 9 inside the fixed base 7. The new lifting ring 5 can then be installed on the machine body 4 for use.

[0036] like Figure 4 As shown, two guide rods 10 on both sides are fitted with fixed springs 11 near the center. The two fixed springs 11 on both sides are symmetrically arranged with the center of the inner cavity of the adjacent insert plate 9 as the axis of symmetry, and the two ends of the two fixed springs 11 on both sides are connected to the center of one side of the adjacent guide plate 12.

[0037] The elastic reset function of the two fixed springs 11 on both sides enables the two fixed springs 11 on both sides to quickly drive the two adjacent guide plates 12 to slide to both sides on the two adjacent guide rods 10.

[0038] like Figure 1 and Figure 2As shown, the top side of the fixed frame 31 is provided with two fixed ears 34, and one side of each fixed ear 34 is connected to the center of the top side of the body 4. The center of one side of each fixed ear 34 is movably connected to a threaded rod 33. A drive sleeve 32 is sleeved on the threaded rod 33 near the bottom end, and the center of one side of the drive sleeve 32 is connected to the top side of the fixed frame 31. A drive hole is opened at the center of the inner cavity of the drive sleeve 32, and the inner wall of the drive hole is provided with an internal thread that matches the threaded rod 33.

[0039] When the operator uses the cable oscillation wave testing device to test the cable, they first power the machine body 4. Then, the operator operates the control panel buttons to power the drive motor 35. When powered on, the drive motor 35 drives the threaded rod 33 to rotate forward. This rotation of the threaded rod 33, via the drive sleeve 32, moves the fixed frame 31 upward. This upward movement of the fixed frame 31, via the connecting cylinder 2, moves the base 1 upward. As the base 1 moves upward, it causes the four casters to gradually separate from the ground in the working area, allowing the bottom of the machine body 4 to quickly contact the ground. This allows the cable oscillation wave testing device to be placed stably on the ground in the work area for testing. When the operator needs to move the cable oscillation wave testing device to different locations in the work area, the operator can operate the control panel button again to power the drive motor 35, which will drive the threaded rod 33 to rotate in the opposite direction. This will cause the four casters on the base 1 to move downwards and contact the ground in the work area, making it easier for the operator to move the cable oscillation wave testing device to different locations in the work area. This improves the mobility of the cable oscillation wave testing device to a certain extent.

[0040] like Figure 1 As shown, a drive motor 35 is provided on the top of the fixed ear 34 located at the top, and the bottom of the drive motor 35 is connected to the center of one side of the top of the adjacent fixed ear 34. A rotating hole is opened in the center of the inner cavity of the fixed ear 34 located at the top, and the bottom end of the power output shaft of the drive motor 35 passes through the inner cavity of the rotating hole and is connected to the center of the top of the threaded rod 33.

[0041] The operator uses the control buttons on the control panel to supply power to the drive motor 35, which allows the drive motor 35 to quickly drive the threaded rod 33 to rotate in the forward or reverse direction when powered on.

[0042] like Figure 1As shown, the threaded rod 33 has two connecting ears 36 on one side, and one side of each connecting ear 36 is connected to the center of the other side of the top of the machine body 4. The center of one side of each connecting ear 36 is connected to a limit rod 37. A limit sleeve 38 is fitted on the limit rod 37 near the bottom. A connecting frame 39 is connected to the center of one side of the limit sleeve 38, and the bottom side of the connecting frame 39 is connected to the center of the other side of the top of the connecting cylinder 2.

[0043] When the base 1 moves up or down, the connecting tube 2 can drive the connecting frame 39 to move up or down. When the connecting frame 39 moves up or down, it can drive the limiting sleeve 38 to slide on the limiting rod 37, thereby limiting the position of the base 1 and allowing the base 1 to move up or down smoothly.

[0044] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
