Description

Technical Field

[0001] The utility model relates to the technical field of cable detection, in particular to a cable quality detection device. Background Art

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables. Cable quality testing devices are a type of cable testing equipment that can test cable winding and tensile strength. They are suitable for testing cables of various specifications.

[0003] However, when installing cables for testing, the cables to be tested are often wrapped around a winding bracket for multiple turns to secure them. The connection is knotted due to the reduction in strength and is prone to breakage at the connection, resulting in inaccurate test results. Winding the cable also takes a long time, which reduces the efficiency of the test. Utility Model Content

[0004] The purpose of the present invention is to solve the following shortcomings in the prior art, that is, the strength of the connection is reduced due to entanglement and knotting, and it is easy to break at the connection, resulting in inaccurate test results, and a cable quality detection device is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A cable quality detection device comprises a base plate and a rotating rod, wherein the rotating rod is rotatably connected to the upper end surface of the base plate;

[0007] The cam is connected to the push rod by a threaded connection, and the second fixing plate is threadedly connected to the push rod. The first fixing plate is connected to the second fixing plate by a threaded connection, and the first fixing plate and the second fixing plate are both provided with a plurality of mounting grooves. The splint is slidably connected in the mounting groove, the airbag is fixedly connected to the side wall of the splint, the sealing cavity is fixedly connected to the inner side wall of the mounting groove, the piston plate is slidably connected to the inner side wall of the sealing cavity, the push rod is fixedly connected to one end of the piston plate, the push rod is slidably connected to one side wall of the sealing cavity, the push plate is fixedly connected to one end of the push rod away from the piston plate, and the splint is slidably connected to the push plate.

[0008] Preferably, the fixing mechanism further includes a sliding rod, two of the sliding rods are fixedly connected to an end of the splint away from the airbag, the two sliding rods are symmetrically arranged, and are respectively slidably connected to the inner side walls of the mounting groove.

[0009] Preferably, both ends of the upper end surface of the splint are fixedly connected with pull plates, and one side wall of each of the two pull plates is fixedly connected with a handle.

[0010] Preferably, two clamping springs are fixedly connected between the clamping plate and the mounting groove, and a reset spring is fixedly connected between the push plate and the mounting groove.

[0011] Preferably, the rotating rod is fixedly connected to a rotating ring, and an air guide tube is fixedly connected between the airbag and the sealed cavity.

[0012] Preferably, the upper end surface of the base plate is fixedly connected to a limit rod, the limit rod is slidably connected to the first fixed plate, the limit rod is slidably connected to the second fixed plate, and a scale is provided on the limit rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. Through the coordination of the splint, sealing cavity, airbag and other structures, the airbag is used to fix the cable. Because it is flexible contact and does not need to be knotted, it is not easy to break at the connection, ensuring the accuracy of the test results.

[0015] 2. By adopting the coordination of pull plates, handles and other structures, pulling the handle can drive the pull plates and thus drive multiple clamps to move, so that multiple cables can be fixed at one time. Compared with winding, it saves time and effort and is very fast, thus improving the efficiency of cable detection.

[0016] 3. Through the coordination of the splint, two fixing plates and other structures, because the two ends of the cable are clamped instead of being entangled, it is only necessary to tighten the two ends of the cable to easily keep the length of the cable between the two splints consistent. Therefore, multiple cables can be tensile tested at the same time, which improves the efficiency of cable testing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] The terms "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not intended to limit the scope of application of the present invention. Changes or adjustments to their relative relationships shall be deemed to be within the scope of application of the present invention without substantially changing the technical content.

[0024] Reference Figures 1-4 A cable quality detection device includes a base plate 1 and a rotating rod 2. The rotating rod 2 is rotatably connected to the upper end surface of the base plate 1, and the rotating rod 2 is fixedly connected to a swivel 16.

[0025] A fixing mechanism is provided on the rotating rod 2, which includes a first fixing plate 3, a second fixing plate 4, a splint 5, an airbag 6, a sealing chamber 7, a piston plate 8, a push rod 9, and a push plate 10. The first fixing plate 3 is rotatably connected to the rotating rod 2, and a thread is provided on the rotating rod 2. The second fixing plate 4 is threadedly connected to the rotating rod 2. A plurality of mounting grooves are provided on the first fixing plate 3 and the second fixing plate 4. The splint 5 is slidably connected in the mounting groove. The airbag 6 is fixedly connected to the side wall of the splint 5. The splint 5 is close to the airbag 6. One side is arc-shaped, which better fits the shape of the cable. The sealed cavity 7 is fixedly connected to the inner wall of the mounting groove. An air guide tube 17 is fixedly connected between the airbag 6 and the sealed cavity 7. The piston plate 8 is sealingly and slidingly connected to the inner wall of the sealed cavity 7. The push rod 9 is fixedly connected to one end of the piston plate 8. The push rod 9 is slidingly connected to one side wall of the sealed cavity 7. The push rod 9 and the sealed cavity 7 are not sealed. The push plate 10 is fixedly connected to the end of the push rod 9 away from the piston plate 8, and the splint 5 is slidingly connected to the push plate 10.

[0026] The fixing mechanism further includes a slide bar 11 . Two slide bars 11 are fixedly connected to one end of the splint 5 away from the airbag 6 . The two slide bars 11 are symmetrically arranged and are respectively slidably connected to the inner side walls of the mounting groove.

[0027] Pull plates 12 are fixedly connected to both ends of the upper end surface of the splint 5, and handles 13 are fixedly connected to one side wall of the two pull plates 12. Two clamping springs 14 are fixedly connected between the splint 5 and the mounting groove, and a reset spring 15 is fixedly connected between the push plate 10 and the mounting groove.

[0028] The upper end surface of the base plate 1 is fixedly connected to a limit rod 18, the limit rod 18 is slidably connected to the first fixed plate 3, and the limit rod 18 is slidably connected to the second fixed plate 4. The limit rod 18 limits the second fixed plate 4 to prevent the second fixed plate 4 from rotating when moving on the rotating rod 2. A scale is provided on the limit rod 18. The scale is used to observe the distance between the first fixed plate 3 and the second fixed plate 4, as well as the distance moved by the second fixed plate 4 after the cable breaks, so as to facilitate and intuitively calculate the cable stretching rate.

[0029] In the present invention, when in use, first rotate the swivel 16 to adjust the distance from the first fixed plate 3 to the second fixed plate 4 by driving the rotating rod 2 to rotate, and adjust it to a suitable position, which is convenient for calculation according to the length after stretching. Then pull the handle 13 on the first fixed plate 3 to drive the pull plate 12 to move in the direction of the handle 13. The pull plate 12 drives the push plate 10 to move in the direction of the handle 13 by driving the clamping plate 5. The clamping plate 5 drives the slide rod 11 to move and compress the clamping spring 14. The push plate 10 drives the piston plate 8 to move away from the sealing chamber 7 through the push rod 9 and compresses the reset spring 15. The piston plate 8 and the sealing chamber are in a closed position. The space between the sealing chamber 7 increases and becomes a negative pressure. The gas in the airbag 6 enters the sealing chamber 7 along the air guide tube 17. The airbag 6 becomes deflated, and a gap is formed between the splint 5 and the mounting groove. Multiple cables are placed in the gaps respectively, and then the handle 13 is released. Under the elastic force of the clamping spring 14 and the return spring 15, the splint 5 and the piston plate 8 are reset, and the space between the piston plate 8 and the sealing chamber 7 is reduced and becomes a positive pressure. The gas in the sealing chamber 7 enters the airbag 6 along the air guide tube 17. Under the clamping force of the clamping spring 14, the airbag 6 clamps the cable tightly. Since it is a flexible contact, the cable is not easy to break at the connection.

[0030] When the lower ends of multiple cables are fixed, the handle 13 on the first fixing plate 3 is pulled, and the upper ends of the multiple cables are passed through the mounting grooves of the second fixing plate 4 in turn. The cables are tightened with force. Similarly, the handle 13 is released to clamp the upper ends of the multiple cables tightly again, so that the middle lengths of the clamped ends of the multiple cables are consistent. Therefore, multiple cables can be tested at the same time. By rotating the swivel 16 to drive the rotating rod 2 to rotate, the second fixing plate 4 is raised, thereby stretching the multiple cables. Slowly rotate the swivel 16 to reduce the error. When one of the cables breaks, observe the scale on the limit rod 18 and record the reading. When all the cables are broken, divide the reading by the initial distance between the first fixing plate 3 and the second fixing plate 4 in turn. When adjusting the initial distance between the two plates, an integer such as ten centimeters should be selected for convenience of calculation. The stretching rate is the length after stretching divided by the initial reading.

[0031] In the present invention, unless otherwise clearly specified or limited, the terms “installed”, “connected”, “connected”, “fixed” and the like should be understood in a broad sense.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
