Description

Technical Field

[0001] This application relates to the field of cable testing technology, specifically a cable continuity testing device. Background Technology

[0002] A cable continuity tester is a specialized instrument used to detect whether a wire, cable, or conductor is conducting or disconnected. Its working principle is mainly based on the transmission and detection of electrical signals.

[0003] The testing device first generates an electrical signal of a specific frequency and amplitude through a signal generator. This signal is applied to one end of the cable under test through a probe. The electrical signal propagates along the cable. If the cable is intact, the signal will be transmitted to the other end without obstruction. At the other end of the cable, a sensor captures the transmitted electrical signal, converts it into a processable electrical signal, and transmits it to the control module. The control module analyzes and processes the received signal. If the signal strength is within a preset threshold range, it indicates that the cable is conductive; if the signal strength is below the threshold or there is no signal at all, it indicates that there is an open circuit in the cable.

[0004] During cable testing, the probe and sensor of the testing tool need to be fixed to both ends of the cable. At this time, the testing tool is held by two fingers of one hand, and the other three fingers are used in conjunction with the palm to hold one end of the cable. The coordination of the five fingers of the hand helps to keep the testing tool and one end of the cable in contact. However, this method can accelerate the fatigue of the operator during prolonged operation, and it is easy to cause the testing tool to separate from the cable unintentionally, resulting in inaccurate test data. Utility Model Content

[0005] The purpose of this application is to provide a cable continuity testing device to solve the problem that the method mentioned in the background art will accelerate the fatigue of personnel during long-term operation, and may inadvertently cause the testing tool to separate from the cable, resulting in inaccurate test data.

[0006] To achieve the above objectives, this application provides the following technical solution: This utility model provides a cable continuity testing device, including: a testing instrument body, a probe, a rotating clamping assembly, and an auxiliary storage assembly. The testing device body consists of a testing instrument body and a detection tool connected to the testing instrument body via a cable. The detection tool consists of a probe and a sensor. The rotating clamping assembly is disposed inside the testing instrument body. The rotating clamping assembly includes a groove formed on the front of the testing instrument body, two sets of first shafts rotatably disposed on both sides inside the groove, a fixing block fixed on the first shaft, an L-shaped groove formed at one end of the fixing block, a guide rod welded inside the L-shaped groove, a clamping block slidably connected to the guide rod, and a spring sleeved on the guide rod. The auxiliary storage assembly is disposed inside the groove.

[0007] By adopting the above technical solution, the cable can be stored by rotation, and it can be stably clamped during use.

[0008] Preferably, the auxiliary storage component includes a toothed block disposed at the other end of the fixed block.

[0009] By adopting the above technical solution, structural meshing can be achieved, thereby achieving synchronous rotation.

[0010] Preferably, the auxiliary storage component further includes a second shaft rotatably connected to one side of the groove and a first gear fixed on the second shaft, wherein the first gear meshes with the teeth of one set of the fixed blocks.

[0011] By adopting the above technical solution, the No. 1 gear can drive the meshing tooth blocks to rotate during the rotation process.

[0012] Preferably, the auxiliary storage component further includes a third shaft rotatably connected to the other side of the groove and a second gear fixed on the third shaft. The second gear meshes with the toothed blocks of another set of fixed blocks, and the second gear meshes with the first gear.

[0013] By adopting the above technical solution, the No. 2 gear can drive the No. 1 gear to rotate together during the rotation process.

[0014] Preferably, the auxiliary storage component further includes a fourth shaft rotatably connected inside the groove, a third gear and a dial fixed at both ends of the fourth shaft.

[0015] By adopting the above technical solution, the rotation of the dial can drive the third gear to rotate as well.

[0016] Preferably, the auxiliary storage component further includes a fourth gear fixed on the third shaft and a chain sleeved on the third and fourth gears.

[0017] By adopting the above technical solution, the chain can drive the fourth gear to rotate simultaneously while the third gear is rotating.

[0018] In summary, this application includes at least one of the following beneficial effects:

[0019] By incorporating a rotating clamping assembly, the assembly can be rotated out of the main body of the testing instrument to clamp and fix both ends of the cable, ensuring the stability of the probe when inserted into both ends of the cable and improving the convenience of testing. When not in use, the rotating clamping assembly can be rotated back into the main body of the testing instrument, reducing the area occupied when not in use.

[0020] By incorporating a rotating clamping assembly and an auxiliary storage assembly, the auxiliary storage assembly allows personnel to manually rotate the disc when the rotating clamping assembly needs to be rotated, thus quickly removing the two sets of clamping blocks from inside the main body of the testing instrument. This greatly improves the smoothness and speed of operation. Attached Figure Description

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] The following is in conjunction with the appendix Figure 1-4 The embodiments of this application will be described in further detail. Example

[0028] Please see Figures 1-4 This embodiment provides a technical solution: a cable continuity testing device, comprising: a testing instrument body 1, a probe 2, a rotating clamping assembly 3, and an auxiliary storage assembly 4;

[0029] The main body of the testing device consists of a testing instrument body 1 and a detection tool 2 connected to the testing instrument body 1 by wires. The detection tool 2 consists of a probe and a sensor. The above is the prior art and will not be described in detail below.

[0030] The rotating clamping assembly 3 is located inside the main body 1 of the testing instrument. The rotating clamping assembly 3 includes a groove 301 on the front of the main body 1 of the testing instrument, a first shaft 302 rotatably disposed on both sides inside the groove 301, two sets of first shafts 302, a fixing block 303 fixed on the first shaft 302, an L-shaped groove 304 opened at one end of the fixing block 303, a guide rod 305 welded inside the L-shaped groove 304, a clamping block 306 slidably connected to the guide rod 305, and a spring 307 sleeved on the guide rod 305. An auxiliary storage assembly 4 is located inside the groove 301.

[0031] The probe and sensor of the testing tool 2 are connected to the main body 1 of the testing instrument via a wire. By manually rotating and turning the auxiliary storage component 4, the auxiliary storage component 4 can quickly remove the rotating clamping component 3 from the inside of the main body 1 of the testing instrument, so that the two ends of the cable can be clamped by the rotating clamping component 3. The probe and sensor of the testing tool 2 are fixed at the two ends of the cable respectively. The testing work can be quickly performed by operating the main body 1 of the testing instrument.

[0032] When the two sets of fixing blocks 303 rotate out of the groove 301 through the first shaft 302, the two ends of the cable are pressed and displaced into the L-shaped groove 304 of the fixing block 303. At this time, the spring 307 in the L-shaped groove 304 will squeeze the clamping block 306, and the clamping block 306 moves stably on the guide rod 305, thereby clamping and fixing the cable. Example

[0033] Please see Figures 1-4 This embodiment provides a technical solution: a cable continuity testing device, including: an auxiliary storage component 4;

[0034] The auxiliary storage component 4 includes a toothed block 401 disposed at the other end of the fixed block 303.

[0035] A second shaft 402 is rotatably connected to one side of the groove 301 and a first gear 403 is fixed on the second shaft 402. The first gear 403 meshes with the toothed blocks 401 of one set of fixed blocks 303. A third shaft 404 is rotatably connected to the other side of the groove 301 and a second gear 405 is fixed on the third shaft 404. The second gear 405 meshes with the toothed blocks 401 of another set of fixed blocks 303. The second gear 405 meshes with the first gear 403. A fourth shaft 406 is rotatably connected to the groove 301. A third gear 407 and a turning disc 408 are fixed at both ends of the fourth shaft 406. A fourth gear 409 is fixed on the third shaft 404 and a chain 410 is sleeved on the third gear 407 and the fourth gear 409.

[0036] Rotation is achieved by holding the dial 408 on the fourth shaft 406. During the rotation of the fourth shaft 406, the third gear 407 on the fourth shaft 406 will also rotate. At this time, the fourth gear 409, which is connected to the third gear 407 via the chain 410, will also rotate. The second gear 405 on the third shaft 404, which is connected to the fourth gear 409, will rotate synchronously. Because the second gear 405 meshes with the tooth block 401 of the fixed block 303, it will drive one set of fixed blocks 303 to rotate together during rotation. Because the second gear 405 meshes with the first gear 403 on the second shaft 402, the first gear 403 meshes with another set of fixed blocks 303, thus achieving a total of two sets of fixed blocks 303 rotating together.

[0037] The implementation principle of the cable continuity testing device of this application is as follows:

[0038] First, connect the probe and sensor of the testing tool 2 to the main body 1 of the testing instrument via a wire. By manually rotating and turning the auxiliary storage component 4, the auxiliary storage component 4 can quickly remove the rotating clamping component 3 from the inside of the main body 1 of the testing instrument, so as to clamp both ends of the cable by rotating the clamping component 3. The probe and sensor of the testing tool 2 are fixed at both ends of the cable respectively. The testing work can be quickly performed by operating the main body 1 of the testing instrument.

[0039] Secondly, the rotation is achieved by manually rotating the dial 408 on the fourth shaft 406. During the rotation of the fourth shaft 406, the third gear 407 on the fourth shaft 406 will rotate together. At this time, the fourth gear 409, which is connected to the third gear 407 via the chain 410, will also rotate. The second gear 405 on the third shaft 404, which is connected to the fourth gear 409, will rotate synchronously. Because the second gear 405 meshes with the tooth block 401 of the fixed block 303, it will drive one set of fixed blocks 303 to rotate together during rotation. Because the second gear 405 meshes with the first gear 403 on the second shaft 402, the first gear 403 meshes with another set of fixed blocks 303, thus achieving a total of two sets of fixed blocks 303 rotating together.

[0040] Finally, when the two sets of fixing blocks 303 rotate out of the groove 301 through the first shaft 302, the two ends of the cable are pressed and displaced into the L-shaped groove 304 of the fixing block 303. At this time, the spring 307 in the L-shaped groove 304 will squeeze the clamping block 306, and the clamping block 306 moves stably on the guide rod 305, thereby clamping and fixing the cable.

[0041] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
