Description

Technical Field

[0001] The present invention relates to the technical field of power line detection equipment, in particular to a multi-performance detection device for a single-station power line. Background Art

[0002] In modern society, power cords are the key carriers of power transmission, and their quality is directly related to power safety and the normal operation of equipment. With the popularization of electronic devices and the complexity of power usage scenarios, power cords face more stringent performance tests, which also promotes the continuous development of power cord detection technology.

[0003] When using the existing single-station multi-performance testing device for power cords, the bending and swing test evaluates the durability and fatigue resistance of the power cord by repeatedly bending and swinging it. In the existing technology, this test requires the use of a bending and swing tester. Usually, the power cords must be placed one by one in the swing device, and then the power cord connectors must be clamped one by one through multiple sets of screws before the test can be carried out. This process is cumbersome and leads to low overall test efficiency.

[0004] After searching, it was found that patent publication number CN118641378B discloses a power cord testing device and testing method. The device uses an eccentric rubber cylinder as a clamping mechanism, and quickly clamps the power cord connector by pressing it between the eccentric rubber cylinders. When disassembling, the eccentric rubber cylinder can be driven to rotate and reset only by the friction between the power cord connector and the eccentric rubber cylinder.

[0005] However, in actual use, we found that when installing the power cord into the eccentric sleeve, it is necessary to place the power cords one by one and press the connector to achieve quick clamping. This one-by-one operation method has an efficiency bottleneck in the installation stage. After the inspection is completed, the power cords need to be pulled one by one to be removed. Both installation and disassembly are cumbersome and time-consuming. Especially when facing batch inspection needs, this operation mode will significantly extend the inspection cycle and is difficult to adapt to efficient production inspection scenarios. For this reason, we propose a single-station multi-performance detection device for power cords. Summary of the Invention

[0006] A technical problem to be solved by this application is: how to design a single-station power cord multi-performance detection device that can quickly install, place and detect power cords. To solve the above technical problems, the present invention provides a multi-performance testing device for a single-station power cord, comprising a body, an electric rotating disk, and two side panels.

[0007] In some embodiments, a connecting groove is provided inside the connecting plate and is movably connected to the two arc-shaped clamping plates. The contact clamping assembly includes two L-shaped plates arranged at the bottom of the two arc-shaped clamping plates. A double-headed screw is threadedly provided between the two L-shaped plates. A fixing block for installing the double-headed screw is provided at the bottom of the connecting plate, and limiting disks are provided at both ends of the double-headed screw.

[0008] In some embodiments, a coaxial shaft is provided on the end face of the limiting plate, a worm gear is provided on the outer fixed sleeve of the coaxial shaft, a worm gear meshing with the worm gear is movably provided on the bottom of the connecting plate, and a gear 2 is provided on the bottom end of the worm gear.

[0009] In some embodiments, a rotating rod is movably provided at the bottom of the connecting plate, and a gear 1 that meshes with gear 2 is sleeved on the outer side of the rotating rod, and a special-shaped rod is fixedly provided at the bottom of the movable frame, and a rack 1 that meshes with gear 1 is provided at the end of the special-shaped rod, and sliding grooves are provided on the sides of the connecting plate and the side plates, and a sliding rail movably connected to the inside of the sliding groove is provided on the side of the movable frame, and an auxiliary part for squeezing the power cord is provided inside the sliding rail.

[0010] In some embodiments, the stripping mechanism includes an extrusion block movably arranged inside the moving frame, a plurality of springs are arranged between the extrusion block and the inner wall of the moving frame, and a pull rod penetrating the moving frame is arranged on the side of the extrusion block.

[0011] In some embodiments, an inclined groove is opened on the inner side of the movable frame, and multiple connecting shafts are movably arranged inside the inclined groove. The outer sides of the multiple connecting shafts are all sleeved with rollers, the bottom ends of the multiple connecting shafts all pass through the connecting shafts, and a synchronous belt is set at the end.

[0012] In some embodiments, a gear three is provided at the bottom end of one of the connecting shafts, two support rods are provided on the side of the connecting plate, and the ends of the two support rods are provided with a rack two that meshes with the gear three.

[0013] In some embodiments, the tension adjustment assembly includes limit plates arranged on both sides of the inner wall of the machine body, the top of the two limit plates are provided with electric telescopic rods, the top of the two electric telescopic rods are provided with lifting plates, and tension springs are provided between the lifting plates and multiple adjacent connecting plates. A straight groove is provided on the inner side of the side plate, and a movable block movably connected to the inner wall of the straight groove is provided on the side of the connecting plate.

Under the coordinated action of spring 1 and the extrusion block, the power cords will be synchronously squeezed into the placement slot on the side of the connecting plate. At the same time, the displacement of the movable frame will drive the rack to engage with gear 1 on the connecting plate, thereby triggering the contact clamping assembly to quickly tighten and fix the power cords in the placement slot. This can quickly complete the rapid positioning and clamping of multiple power cords, significantly improving installation efficiency. 2. When the power cord enters the placement slot and the two arc-shaped clamping plates are not yet fully fixed, the auxiliary parts will automatically start to apply squeezing force to the power cord to ensure that the power cord that is not fully inserted into the slot is completely inserted into the slot. Then, under the action of the arc-shaped clamping plates, the power cord is firmly clamped, effectively preventing the problem of detachment caused by incomplete insertion of the slot and improving the reliability and stability of the clamping; 3. By setting up a slitting mechanism, pulling the rod between the two moving frames can drive the two to move synchronously, so that the two slitting mechanisms can place the power cords into the placement slots of the corresponding connecting plates in turn, thereby achieving rapid clamping and detection.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1 See also Figure 1-12 , the present invention provides a technical solution: A multi-performance testing device for a single-station power cord comprises a body 1, an electric rotating disk 2, and two side panels 3. Multiple end-to-end connecting plates 5 are provided on the inner sides of each of the two side panels 3. Two arc-shaped clamping plates 8 are movably provided inside each of the multiple connecting plates 5. Two movable frames 4 are provided on the sides of the two side panels 3 and the multiple connecting plates 5. A tension adjustment assembly 7 is provided on the multiple connecting plates 5 at the bottom of the body 1. The side of the movable frame 4 is provided with an opening having a diameter the same as the diameter of the wire. The movable frame 4 is provided with a stripping mechanism 9 for separating and pushing out the wires. The connecting plate 5 is provided with a contact clamping assembly 6 that contacts and cooperates with the movable frame 4. The electric rotating disk 2 has an axis rod running through the side and is connected to the connecting plate 5. When rotating, it can play the role of bending detection. A placement groove is opened on the side of the connecting plate 5, which is a groove for placing the power cord and matches the power cord to be detected. A handle is set on the side of the movable frame 4 to facilitate use by the staff.

[0021] The connecting plate 5 has a connecting groove 61 formed inside thereof and movably connected to the two arc-shaped clamping plates 8. The contact clamping assembly 6 includes two L-shaped plates 64 disposed at the bottom of the two arc-shaped clamping plates 8. A stud screw 65 is threadedly disposed between the two L-shaped plates 64. A fixing block 66 for mounting the stud screw 65 is disposed at the bottom of the connecting plate 5. Limiting plates 67 are disposed at both ends of the stud screw 65. The thread directions of the double-headed screw 65 are opposite, so that when rotating, the two L-shaped plates 64 can move relative to each other. The function of the fixed block 66 is to limit the double-headed screw 65. The inner side of the arc-shaped clamping plate 8 is provided with multiple vertical anti-slip grooves, which can prevent the power cord from rotating during the full test, thereby causing the power cord to become tangled.

[0022] The end surface of the limiting plate 67 is provided with a concentric shaft 611, and the outer fixed sleeve of the concentric shaft 611 is provided with a worm gear 69. The bottom of the connecting plate 5 is movably provided with a worm 68 that meshes with the worm gear 69, and the bottom end of the worm 68 is provided with a gear 2 612; The limiting effect provided by the worm gear 69, the worm gear 69 and the double-headed screw 65 can prevent the two arc-shaped clamping plates 8 from automatically separating. By rotating gear 2 612, the worm 68 on the outer surface of the concentric shaft 611 can be driven to rotate, and then the worm 68 drives the worm gear 69 to rotate, and the worm gear 69 will drive the limiting plate 67 and the double-headed screw 65 to rotate through the concentric shaft 611.

[0023] A rotating rod 610 is movably provided at the bottom of the connecting plate 5, and a gear 1 62 meshing with a gear 2 612 is sleeved on the outer side of the rotating rod 610. A special-shaped rod 615 is fixedly provided at the bottom of the movable frame 4, and a rack 1 614 meshing with the gear 1 62 is provided at the end of the special-shaped rod 615. Slide grooves 63 are provided on the sides of the connecting plate 5 and the side plate 3. A slide rail 613 movably connected to the inside of the slide groove 63 is provided on the side of the movable frame 4, and an auxiliary part 616 for squeezing the power cord is provided inside the slide rail 613.

[0024] The slitting mechanism 9 includes an extrusion block 94 movably arranged inside the moving frame 4, and a plurality of springs 2 95 are arranged between the extrusion block 94 and the inner wall of the moving frame 4. A pull rod 93 is arranged on the side of the extrusion block 94 that passes through the moving frame 4. In this way, the moving frame 4 can stop on the side when not in use, so as not to affect the rotation of the multiple connecting plates 5. Pulling the pull rod 93 can drive the extrusion block 94 to squeeze the spring 1 6163 first, and then directly insert multiple power cords. How to release the pull rod 93, the spring 1 6163 drives the extrusion block 94 to squeeze the power cord, so that the power cord can only move toward one outlet. When it reaches the placement slot, only one power cord can pass through and enter the placement slot. The side of the extrusion block 94 that extrudes the power cord is set as an inclined surface, which is convenient for squeezing all the power cords out, and the extrusion block 94 is also provided with a protrusion at the opening of the moving frame 4 to send the power cord that needs to enter the placement slot a longer distance.

[0025] An inclined groove 96 is provided on the inner side of the movable frame 4, and a plurality of connecting shafts 98 are movably provided inside the inclined groove 96. The outer sides of the plurality of connecting shafts 98 are sleeved with rollers 97. The bottom ends of the plurality of connecting shafts 98 pass through the connecting shafts 98, and a synchronous belt 99 is provided at the end.

[0026] A gear 3 910 is provided at the bottom end of one of the connecting shafts 98 , and two support rods 92 are provided on the side of the connecting plate 5 , and the ends of the two support rods 92 are provided with a rack 2 91 that meshes with the gear 3 910 ; When the rack 2 91 contacts the gear 3 910, multiple connecting shafts 98 can be rotated through the synchronous belt 99. At this time, there are two racks 2 91, and they are placed in opposite directions. When in use, the rollers 97 on both sides of the moving frame 4 will rotate in the same direction. At this time, the internal power cord will be transported out to avoid squeezing, which will cause the power cord to get stuck together and unable to enter the placement slot.

[0027] Example 2 See also Figure 6 and Figure 8 , the present invention provides a technical solution: A groove 6161 is formed on the side of the slide rail 613. The auxiliary member 616 includes a wedge 6162 movably arranged on the inner wall of the groove 6161. A spring 1 6163 is provided between the wedge 6162 and the movable frame 4. When the slide rail 613 enters the outer side of the placement groove, the wedge 6162 enters the placement groove under the action of the spring 2 95. At this time, the power cord in the placement groove is squeezed and squeezed into the two arc-shaped clamping plates 8 to prevent it from detaching. Furthermore, both sides of the wedge 6162 are provided with inclined surfaces, so that after the extrusion work is completed, it will contact the inner side of the placement groove, thereby completing the contraction; Moreover, there is a groove with a certain limiting function at the groove 6161, which corresponds to the protruding block on the outer surface of the wedge block 6162, so as to prevent the wedge block 6162 from escaping from the groove 6161 under the action of the spring 2 95.

[0028] Example 3 See also Figure 1 、 Figure 9 and Figure 10 , the present invention provides a technical solution: It includes limit plates 71 arranged on both sides of the inner wall of the body 1, and the tops of the two limit plates 71 are each provided with an electric telescopic rod 74. The tops of the two electric telescopic rods 74 are provided with lifting plates 72. Tension springs 73 are provided between the lifting plates 72 and multiple adjacent connecting plates 5. A straight groove 75 is opened on the inner side of the side plate 3, and a movable block 76 is provided on the side of the connecting plate 5 and is movably connected to the inner wall of the straight groove 75; By starting the electric telescopic rod 74 to drive the lifting plate 72 to move up and down, the tension spring 73 between the lifting plate 72 and the connecting plate 5 is deformed. The different deformation lengths of the tension spring 73 will provide different tensions. Therefore, the deformation length of the tension spring 73 can be controlled to adjust the tension of the power cord bending detection.

[0029] When using this device, first pull the pull rod 93 to drive the squeezing block 94 to squeeze the spring 1 6163, and then put multiple power cords directly into the squeezing block 94 and the inner wall of the moving frame 4. At this time, by moving the moving frame 4, the moving frame 4 is made to enter the chute 63 opened on the side of the connecting plate 5 from the chute 63 opened on the side of the side plate 3. At this time, the opening of the moving frame 4 is aligned with the placement groove, and a power cord is squeezed into the placement groove under the action of the squeezing block 94. At this time, the rack will contact the outer surface of the gear 1 62, driving the gear 2 612 to rotate. Before the second gear 612 rotates, the wedge 6162 is squeezed into the placement groove of the power cord under the action of the second spring 95, and then the rotation of the first gear 62 drives the second gear 612 to rotate, and the second gear 612 drives the worm 68 to rotate, and the worm 68 drives the worm wheel 69 to rotate. Therefore, the worm wheel 69 drives the double-headed screw 65 to rotate through the concentric shaft 611. When the double-headed screw 65 rotates, it drives the two L-shaped plates 64 on the outer surface to slide inside the connecting groove 61. At this time, the L-shaped plates 64 drive the arc-shaped clamping plate 8 to clamp the power cord entering the placement groove; During the movement of the moving frame 4, the power line inside the moving frame 4 will also enter the placement groove of the connecting plate 5 on the limit plate 71 through the rod between the two moving frames 4. When the moving frame 4 moves, the gear 3 910 will contact the rack 2 91. At this time, the gear 3 910 will rotate. The rotation of the gear 3 910 will drive the synchronous belt 99 to rotate. Therefore, the synchronous belt 99 will drive multiple connecting shafts 98 to rotate synchronously. The connecting shaft 98 will drive the roller 97 on the outer surface to rotate, thereby conveying the power line inside the moving frame 4 to prevent blockage. By adjusting the pulling length of the limit plate 71, the lifting plate 72 is controlled. The lifting plate 72 will drive the tension spring 73 to deform the distance between the connecting plates 5. When the distance is longer, the pulling force will increase. Conversely, during the inspection, the connecting plate 5 on the limit plate 71 will slide in the straight groove 75 through the moving block 76 set on the side, and the straight groove 75 is not completely through the side plate 3, so there will be a limiting place.

[0030] Example 4 See also Figure 11 and Figure 12 , the present invention provides a technical solution: A U-shaped groove 13 is formed on the top of the connecting plate 5. A connecting rod 10 is movably provided on the inner wall of the U-shaped groove 13. A contact rod 11 movably connected to the inner wall of the U-shaped groove 13 is provided on the side of the connecting rod 10. A plurality of springs 12 are provided between the inner wall of the U-shaped groove 13 and the connecting rod 10. When the power cord enters the placement groove, it goes back to squeeze the contact rod 11, so that the contact rod 11 drives the connecting rod 10 to slide into the inner wall of the U-shaped groove 13. At this time, the movable frame 4 can slide to the next connecting plate 5 through the slide groove 63. When the contact rod 11 does not completely enter the U-shaped groove 13, the connecting rod 10 will block the movement of the movable frame 4, thereby reminding the staff to observe and put the power cord into the placement groove. The spring three 12 can drive the connecting rod 10 and the contact rod 11 to reset.
