Description

Technical Field

[0001] This utility model relates to the field of cable conductor diameter measurement technology, specifically a cable conductor diameter detection device. Background Technology

[0002] Cables are typically made up of several or groups of conductors (at least two conductors per group) twisted together in a rope-like manner. Each group of conductors is insulated from each other and is often twisted around a central core. The entire cable is covered with a highly insulating outer layer. Cables are characterized by being internally energized and externally insulated. During the production process, after the cable comes out of the extruder, its surface is covered with a protective sheath. To ensure that the diameter of the protective sheath meets the specified parameters, its diameter needs to be tested.

[0003] According to Chinese Patent Publication No. CN218191102U, a cable conductor diameter detection device is disclosed. This device, through the coordinated arrangement of a handle, a bidirectional threaded rod, and a threaded sleeve, can drive two flat plates to move relative to each other. These flat plates then drive two push rods to move relative to each other and press against the cable body. Simultaneously, the threaded sleeve, through the coordinated arrangement of a push plate, a vertical rod, a horizontal plate, and a push rod, can drive pointers to move. When the push rods press against the side wall of the cable body, the scale values ​​pointed to by the two pointers are recorded. The sum of the two scale values ​​is the diameter of the cable body. The testing is convenient and quick, and can accurately measure the diameter of the cable body, thus improving the practicality of the device.

[0004] In the current technical solution, the cable conductor does not have a positioning structure on the fixing block when it passes through the fixing block. This causes the cable conductor to easily deviate during measurement, which affects the measurement accuracy of the cable conductor. It also requires personnel to hold the cable conductor at all times, which is inconvenient for personnel to operate. Therefore, we propose a cable conductor diameter detection device. Utility Model Content

[0005] The purpose of this invention is to provide a cable conductor diameter detection device, which solves the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cable conductor diameter detection device, comprising a fixed plate, a fixed frame, a measuring frame one, and a measuring frame two. The fixed plate has a through hole. The fixed frame is fixedly installed on the top of the fixed plate. A bidirectional screw is rotatably connected to the fixed frame. The top of the fixed plate has two movable slots. The measuring frame one and measuring frame two are slidably connected to the two movable slots respectively. The bottom ends of the measuring frame one and measuring frame two respectively extend through the two movable slots into the through hole. The measuring frame one and measuring frame two are drively connected to the bidirectional screw one. A pointer is fixedly installed on the front of the measuring frame one and measuring frame two. A scale is provided on the front of the fixed frame.

[0007] A shrinkage groove is formed inside the fixed plate near one side. Fixed frame one and fixed frame two are movably passed through the top and bottom of the shrinkage groove, respectively. One end of fixed frame one and fixed frame two are movably passed through the top and bottom of the fixed plate and extend into the through hole, respectively. Fixed corner blocks are fixedly installed at one end of fixed frame one and fixed frame two. A bidirectional screw two is provided in the shrinkage groove. The two ends of the bidirectional screw two are threadedly connected to the threaded grooves formed at the other ends of fixed frame one and fixed frame two, respectively. A support plate is fixedly installed on the inner wall of the shrinkage groove. The support plate is fixedly sleeved on the outer wall of the bidirectional screw two through bearings. A rotating shaft passes through one side of the fixed plate and is rotatably connected to the fixed plate through bearings. The rotating shaft is drively connected to the bidirectional screw two.

[0008] Preferably, a knob is fixedly installed at one end of the rotating shaft, and one end of the bidirectional screw passes through one side of the fixing frame. A knob is also fixedly installed at one end of the bidirectional screw. By setting knob one and knob two, it is convenient for personnel to rotate the rotating shaft and the bidirectional screw, thereby facilitating personnel operation.

[0009] Preferably, a connecting block is fixedly installed at the top of both the first measuring frame and the second measuring frame. Both connecting blocks are threaded onto the outer wall of the first bidirectional screw. By setting the connecting blocks, the first bidirectional screw can drive the first measuring frame and the second measuring frame to move through the connecting blocks.

[0010] Preferably, a bevel gear 1 is fixedly sleeved on the outer wall of the bidirectional screw 2, and a bevel gear 2 is fixedly installed on the other end of the rotating shaft. The bevel gear 1 and the bevel gear 2 mesh with each other. By setting the bevel gear 1 and the bevel gear 2, the rotating shaft can drive the bevel gear 1 to rotate, which in turn drives the bevel gear 2 to rotate, and finally the bevel gear 2 drives the bidirectional screw 2 to rotate.

[0011] Preferably, an anti-slip pad is fixedly installed on the inner side of the fixed corner block, and a through groove is opened at the top of the fixed frame. The measuring frame moves through the through groove. By setting the anti-slip pad, the friction between the fixed corner block and the cable conductor can be increased, thereby improving the fixing stability.

[0012] Preferably, a support frame is fixedly installed on the other side of the fixed plate. The bottom end of the support frame has an installation hole, and a grip sleeve is fixedly fitted on the outer wall of the support frame.

In addition, by setting the grip sleeve, the comfort of personnel gripping the fixed plate through the support frame can be increased.

[0013] This invention provides a cable conductor diameter detection device. This cable conductor diameter detection device has the following advantages:

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figure 1-5 As shown, this utility model provides a technical solution: a cable conductor diameter detection device, including a fixed plate 1, a fixed frame 2, a measuring frame 4 and a measuring frame 5. The fixed plate 1 has a through hole 9. The fixed frame 2 is fixedly installed on the top of the fixed plate 1. A bidirectional screw 6 is rotatably connected to the fixed frame 2. The top of the fixed plate 1 has a moving groove 3. There are two moving grooves 3. The measuring frame 4 and the measuring frame 5 are slidably connected to the two moving grooves 3 respectively. The bottom ends of the measuring frame 4 and the measuring frame 5 respectively move through the two moving grooves 3 and extend into the through hole 9. The measuring frame 4 and the measuring frame 5 are connected to the bidirectional screw 6. A pointer 10 is fixedly installed on the front of the measuring frame 4 and the measuring frame 5. The fixed frame 2 has a scale 11 on the front.

[0026] A shrinkage groove 16 is provided inside the fixed plate 1 near one side. Fixed frame 12 and fixed frame 2 15 are movably passed through the top and bottom of the shrinkage groove 16, respectively. One end of fixed frame 12 and fixed frame 2 15 are movably passed through the top and bottom of the fixed plate 1 and extend into the through hole 9, respectively. Fixed corner blocks 14 are fixedly installed at one end of fixed frame 12 and fixed frame 2 15. A double-acting screw 2 17 is provided in the shrinkage groove 16. The two ends of the double-acting screw 2 17 are threadedly connected to the threaded grooves opened at the other end of fixed frame 12 and fixed frame 2 15, respectively. A support plate 18 is fixedly installed on the inner wall of the shrinkage groove 16. The support plate 18 is fixedly sleeved on the outer wall of the double-acting screw 2 17 by bearings. A rotating shaft 21 is passed through one side of the fixed plate 1, and the rotating shaft 21 is rotatably connected to the fixed plate 1 by bearings. The rotating shaft 21 is drively connected to the double-acting screw 2 17.

[0027] Specifically, in the above technical solution, when using the cable conductor diameter detection device, the cable conductor to be measured can be passed through the through hole 9. Then, the knob 22 is rotated, which drives the rotating shaft 21 to rotate. The rotating shaft 21 drives the bevel gear 20 to rotate, which in turn drives the bevel gear 19 to rotate. The bevel gear 19 drives the bidirectional screw 17 to rotate. The bidirectional screw 17 drives the fixed frame 12 and the fixed frame 15 to move closer to each other. The fixed frame 15 and the fixed frame 12 respectively drive the fixed corner blocks 14 on them to move towards the cable conductor, ultimately clamping and positioning the cable conductor with the two fixed corner blocks 14. Through the above structure, the cable conductor can be clamped and positioned when passing through the through hole 9, ensuring the stability of the cable conductor during measurement and detection, thereby improving the measurement accuracy and solving the problem. This invention solves the problem in existing technologies where the fixing block lacks a structure to position the cable conductor when it passes through the fixing block, causing the conductor to easily deviate during measurement and affecting the measurement accuracy. It also addresses the inconvenience of requiring personnel to constantly hold the conductor. Once the cable conductor is clamped and positioned, knob 8 can be rotated, causing the bidirectional screw 6 to rotate. The bidirectional screw 6, through two connecting blocks 7, moves measuring frames 4 and 5 closer together, bringing their bottom ends into contact with the two apexes of the cable conductor. The measuring frames 4 and 5 then move their pointers 10, allowing the readings of the pointers 10 on the scale 11 to complete the measurement and detection of the cable conductor diameter.

[0028] Furthermore, a knob 22 is fixedly installed at one end of the rotating shaft 21, and a double-ended screw 6 passes through one side of the fixing frame 2, with a knob 8 fixedly installed at one end of the double-ended screw 6.

[0029] The knobs 21 and 22 facilitate the rotation of the shaft 21 and the bidirectional screw 6, making operation easier.

[0030] Furthermore, connecting blocks 7 are fixedly installed at the top of both measuring frame 4 and measuring frame 5, and both connecting blocks 7 are threaded onto the outer wall of the bidirectional screw 6.

[0031] By setting a connecting block 7, the bidirectional screw 6 can drive the measuring frame 4 and the measuring frame 5 to move through the connecting block 7.

[0032] Furthermore, a bevel gear 19 is fixedly sleeved on the outer wall of the double-acting screw 17, and a bevel gear 20 is fixedly installed on the other end of the rotating shaft 21, with the bevel gear 19 meshing with the bevel gear 20.

[0033] Specifically, by setting bevel gear 19 and bevel gear 20, the rotating shaft 21 can drive bevel gear 19 to rotate, which in turn drives bevel gear 20 to rotate, ultimately causing bevel gear 20 to drive the bidirectional screw 17 to rotate.

[0034] Furthermore, an anti-slip pad 23 is fixedly installed on the inner side of the fixed corner block 14, and a through groove 13 is opened at the top of the fixed frame 12, through which the measuring frame 4 moves.

[0035] By setting anti-slip pads 23, the friction between the fixing corner block 23 and the cable conductor can be increased, thereby improving the fixing stability.

[0036] Furthermore, a support frame 24 is fixedly installed on the other side of the fixing plate 1. The bottom end of the support frame 24 is provided with a mounting hole 25, and a grip sleeve 26 is fixedly sleeved on the outer wall of the support frame 24.

[0037] By setting up a support frame 24 and mounting holes 25, the support frame 24 can be used to fix the fixing plate 1 on the placement surface by fastening bolts. This eliminates the need for personnel to hold the fixing plate 1 at all times, saving manpower and making it easier for personnel to operate. Furthermore, by setting up a grip sleeve 26, the comfort of personnel gripping the fixing plate 1 through the support frame 24 can be increased.

[0038] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
