Referring to fig. 1 to 2, the handheld telescopic detection device in an embodiment of the present invention includes a detection device and a telescopic rod 600 detachably connected to the detection device, wherein the detection device includes a first clamping piece 100, a second clamping piece 200, a support 300, an elastic component 500, and a limiting piece 400. As shown in FIGS. 2 and 3, the first jaw 100 and the second jaw 200 are respectively provided with a shaft hole (121,221), the support post 300 is provided with a corresponding shaft hole (310,320), and the pin (122,222) passes through the shaft holes (121,221, 310,320) and is rotatably connected to the support post 300. The elastic component 500 is connected to the tail portions (130,230) of the first and second jaws, respectively, and the elastic component 500 is used for driving the first and second jaws 100, 200 to rotate relative to the pillar 300, so as to close the head portions of the first and second jaws 100, 200. The second clip 200 has a bayonet 224 at a lower end thereof, and the limiting member 400 can be clamped inside the bayonet 224 to keep the first and second clip heads (110,210) in an open state. The telescopic rod 600 is detachably connected to the position-limiting member 400 and drives the position-limiting member 400 to move relative to the pillar 300.
As shown in fig. 4 and 5, in the using process, the position-limiting member 400 is clamped in the bayonet 224 to keep the first and second clip head portions (110,210) in the open state, the telescopic rod 600 is used to place the detection device at the point 700 to be detected, so that the point 700 to be detected is located between the first and second clip head portions (110,210), or the telescopic rod 600 is used to remove the detection device from the point 700 to be detected. The elastic component 500 drives the first clamping piece 100 and the second clamping piece 200 to rotate, so that the head parts (110,210) of the first clamping piece and the second clamping piece are closed to clamp the point 700 to be detected, thereby realizing the clamping and taking-out operation of the detection device, completing the detection of the point 700 to be detected, and having safe and convenient operation.
The three-phase switches of the magnetic column type circuit breaker are mutually independent, the points to be detected 700 are respectively located on the three-phase switches, and during detection, the detection device needs to be clamped on the points to be detected 700 of the three-phase switches at the same time, so that the detection of the magnetic column type circuit breaker can be realized.
When the hand-held telescopic detection device is used for clamping the point 700 to be detected for detection, firstly, the tail parts (130,230) of the first clamping piece and the second clamping piece are manually clamped, the first clamping piece 100 rotates clockwise relative to the supporting column 300 around the first pin shaft 122, the second clamping piece 200 rotates anticlockwise relative to the supporting column 300 around the second pin shaft 222, the head parts (110,210) of the first clamping piece and the second clamping piece are opened, and the tail parts (130,230) of the first clamping piece and the second clamping piece approach each other to enable the elastic component 500 to be in a compressed state. Then, the telescopic rod 600 pushes the limiting member 400 upwards to clamp the limiting member 400 in the bayonet 224 of the second clamping piece 200, and the limiting member 400 prevents the second clamping piece 200 from rotating relative to the support post 300, so as to maintain the elastic potential energy in the elastic assembly 500. Then, the length of the telescopic rod 600 is adjusted to make the length of the telescopic rod 600 meet the height requirement of the user for detecting the point 700 to be detected, and the detecting device is moved to the point 700 to be detected by the telescopic rod 600 so that the point 700 to be detected is placed between the head portions (110,210) of the first and second jaws. Finally, the telescopic rod 600 is pulled downwards, the telescopic rod 600 drives the limiting member 400 to move downwards relative to the pillar 300, so that the limiting member 400 is separated from the bayonet 224, the elastic assembly 500 releases internal elastic potential energy to drive the first clamping member 100 and the second clamping member 200 to rotate relative to the pillar 300, so that the head portions (110,210) of the first clamping member and the second clamping member are closed, and the point 700 to be detected is clamped. The telescopic rod 700 is separated from the limiting member 400, the clamping operation is repeated, and the plurality of detection devices are clamped on the points 700 to be detected through the telescopic rod 600, so that the detection of the magnetic column type circuit breaker is realized.
When the handheld telescopic detection device is used to take out the detection device from the point 700 to be detected, first, the telescopic rod 600 is pushed upward, and the telescopic rod 600 drives the position-limiting member 400 to move toward the direction close to the second clamping piece 200 relative to the pillar 300. Then, the pushing force on the telescopic rod 600 is increased, the limiting member 400 applies pressure to the bottom of the second clamping piece 200 to drive the second clamping piece 200 to rotate clockwise (shown in fig. 3) around the second pin 222 relative to the support post 300, when the bayonet 224 aligns with the limiting member 400, the limiting member 400 is clamped in the bayonet 224 under the pushing of the telescopic rod 600, and the head portions (110,210) of the first and second clamping pieces are in an open state. The telescopic rod 600 is moved to make the first and second clip head parts (110,210) separate from the point 700 to be detected, so as to take out the detection device from the point 700 to be detected. The above operations are repeated, and a plurality of detection devices are taken out from the point 700 to be detected through one telescopic rod 600.
In one embodiment, in order to improve the stability of the rotation of the first jaw 100 and the second jaw 200 relative to the supporting column, gear teeth (123,223) are provided on the rotating portions (120,220) of the first jaw 100 and the second jaw 200, and the first jaw 100 and the second jaw 200 are engaged and rotated through the gear teeth (123,223) (see fig. 2). When the first and second clips 100 and 200 rotate around the first and second shafts 122 and 222 relative to the support 300, the first and second clips 100 and 200 are engaged with each other via the gear teeth (123,223) to make the first and second clips 100 and 200 rotate synchronously, so as to prevent the first and second clips 100 and 200 from sliding relative to each other, thereby improving the stability of the first and second clips 100 and 200 in rotating relative to the support 300.
When the detection device is clamped on the point 700 to be detected, the first clamping piece 100 and the second clamping piece 200 are meshed and synchronously rotated through the gear teeth (123, 223). That is, the head portions (110,210) of the first and second clips are close to the point 700 to be detected synchronously, so that the point 700 to be detected is located at the middle position between the first clip 100 and the second clip 200, thereby improving the stability of clamping the first clip 100 and the second clip 200 to the point 700 to be detected. When the detection device is taken out from the point 700 to be detected, the first clamping piece 100 and the second clamping piece 200 are meshed through the gear teeth (123,223) to synchronously rotate, so that the sliding between the limiting piece 400 and the rotating parts (120,220) of the first clamping piece 100 and the second clamping piece 200 when the limiting piece 400 drives the second clamping piece 200 to rotate can be avoided, and the difficulty of the detection device in separating from the point 700 to be detected is reduced.
In order to further improve the stability of the first clip 100 and the second clip 200 clamped on the point 700 to be detected, the head parts (111,211) of the first clip and the second clip are provided with sharp teeth, and the first clip 100 and the second clip 200 are clamped on the point 700 to be detected through the sharp teeth (111, 211). As shown in fig. 5, when the point 700 to be detected is clamped by the pointed teeth (111,211) of the first clip 100 and the second clip 200, the force of the pointed teeth (111,211) acts on the point 700 to be detected vertically, so as to prevent the first clip 100 and the second clip 200 from sliding relative to the point 700 to be detected, thereby improving the stability of clamping the first clip and the second clip to the point to be detected.
In one embodiment, as shown in fig. 2 and 4, the position-limiting member 400 includes a locking pin 410 and a transmission shaft 420, one end of the transmission shaft 420 is connected to the locking pin 410, and the other end is detachably connected to the telescopic rod 600. In the process of clamping the point 700 to be detected by the detection device, the telescopic rod 600 pulls the transmission shaft 420 to drive the bayonet 410 to disengage from the bayonet 224, so that the elastic component 500 drives the head portions (110,210) of the first and second clips to clamp the point 700 to be detected. When the detection device is separated from the point 700 to be detected, the telescopic rod 600 pushes the transmission shaft 420 to force the pin shaft 410 to abut against the second clamping piece 200, so that pressure is applied to drive the second clamping piece 200 to rotate, the head parts (110,210) of the first clamping piece and the second clamping piece are opened, and the difficulty of driving the detection device to clamp and separate from the point 700 with the monitoring point by the telescopic rod 210 is reduced.
Further, as shown in fig. 5. In order to improve the stability of the movement of the bayonet 410 and the transmission shaft 420 relative to the connecting column 300, the middle part of the supporting column 300 is provided with a sliding groove 330 for the bayonet 410 to slide, the bottom of the supporting column 300 is provided with a through hole 340 for the transmission shaft 420 to pass through, and the transmission shaft 420 passes through the through hole 340 to be connected to the bayonet 410 and drive the bayonet 410 to slide in the sliding groove 330. In the process that the detection device clamps the point 700 to be detected, the telescopic rod 600 pulls the transmission shaft 420 downwards, the transmission shaft 420 passes through the through hole 340 and slides relative to the support 300, meanwhile, the detent 410 moves downwards relative to the support 300 in the sliding groove 330 along with the transmission shaft 420, and the elastic component 500 drives the first clamping piece 100 and the second clamping piece 200 to clamp the point 700 to be detected. When the detection device is separated from the point 700 to be detected, the telescopic rod 600 is pushed to enable the transmission shaft 420 to pass through the through hole 340 and slide upwards relative to the supporting column 300, meanwhile, the bayonet 410 moves upwards relative to the supporting column 300 in the sliding groove 330 along with the transmission shaft 420, the bayonet 410 drives the first clamping piece 100 and the second clamping piece 200 to rotate and be clamped in the bayonet 224, so that the head parts of the first clamping piece 100 and the second clamping piece 200 are in an open state, and the detection device is separated from the point 700 to be detected.
Furthermore, in order to prevent the driving shaft 420 and the detent 410 from being separated from the detent 224 by the gravity of the driving shaft and the detent 410 being larger than the abutting force of the detent 224 to the detent 410, the limiting device 400 is further provided with a spring 430. The two ends of the spring 430 are respectively abutted to the bottom of the pillar 300 and the bottom of the bayonet 410, and the spring 430 applies an upward acting force to the bayonet 410 to overcome the gravity of the transmission shaft 420 and the bayonet 410, so that the bayonet 410 is prevented from being separated from the bayonet 224 in the clamping process to influence the normal use of the detection device.
Because the position of the point 700 to be detected of the handheld telescopic detection device is higher, the process of connecting the telescopic rod 600 with the transmission shaft 420 and disconnecting the telescopic rod 600 from the transmission shaft 420 is inconvenient. Aiming at the problems, the lower end of the transmission shaft 420 is provided with a first magnetic part 440, the upper end of the telescopic rod 600 is provided with a second magnetic part 620 which is attracted mutually, and the telescopic rod 600 is detachably connected with the transmission shaft 420 through the first magnetic part and the second magnetic part (440,620). In the process that the telescopic rod 600 is connected with the transmission shaft 420, a magnetic field is generated between the first magnetic member 440 at the lower end of the transmission shaft 420 and the second magnetic member 620 at the upper end of the telescopic rod 600. The first magnetic member 440 at the lower end of the transmission shaft 420 actively attracts the second magnetic member 620 at the upper end of the telescopic rod 600 nearby under the action of the magnetic field, so that the upper end of the telescopic rod 600 is quickly connected with the lower end of the transmission shaft 420, and the problem that the upper end of the telescopic rod 600 is difficult to butt with the lower end of the transmission shaft 420 due to shaking of a user is effectively solved. In the process of separating the telescopic rod 600 from the transmission shaft 420, the telescopic rod 600 is directly pulled downwards, so that the downward pulling force overcomes the magnetic attraction of the first magnetic part (440,620) and the second magnetic part (440,620) at the upper end of the telescopic rod 600 and the lower end of the transmission shaft 420, and the telescopic rod 600 can be separated from the transmission shaft 420. Therefore, the difficulty of connection and separation between the telescopic rod 600 and the transmission shaft 420 can be reduced by providing the first magnetic member 440 and the second magnetic member 620.
In one embodiment, as shown in FIG. 1, the telescoping rod 600 is made up of multiple layers of nested tubes, any of which is provided with a clamp 640 at the upper end, the outer nested tube being forced to the inner nested tube by the clamp 640 for length adjustment. By extracting the inner nested tube from the outer nested tube, the length of the telescopic rod 600 meets the height requirement of detecting the point 700 to be detected. The clamp 640 at the end of the outer nested tube is then rotated to force the tube portion of the outer nested tube in contact with the clamp 640 to deform and compress against the inner front sleeve, thereby securing the outer nested tube to the inner front sleeve. Because the position of the inner layer nested pipe relative to the outer layer nested pipe can be adjusted according to the detection requirement, the detection device can be clamped at the detection point with any height, and the universality of the detection device is improved.
In one embodiment, there is a problem that the clamping force applied to the bayonet 410 by the bayonet 224 is too large, and the magnetic attraction between the first magnetic member 440 and the second magnetic member 620 cannot pull the transmission shaft 420, so that the bayonet 410 is separated from the bayonet 224. Aiming at the above problem, the upper end of the telescopic rod 600 is provided with a V-shaped bayonet 630, and the caliber of the V-shaped bayonet 630 is larger than the diameter of the transmission shaft 420 and smaller than the diameter of the second magnetic member. Wherein the V-shaped bayonet 630 is mainly used as a backup function for pulling the transmission shaft 420 downward. When the transmission shaft 420 cannot be pulled by the magnetic attraction between the upper end of the telescopic rod 600 and the lower end of the transmission shaft 420, the V-shaped bayonet 630 can be clamped on the transmission shaft 420, and the transmission shaft 420 is pulled to move downwards. Specifically, when the transmission shaft 420 is pulled downward, the lower end of the V-shaped latch 630 abuts against the second magnetic member 440 and generates a downward acting force on the second magnetic member 440, and the downward acting force is sequentially transmitted to the transmission shaft 420 and the latch 410 through the second magnetic member 440, so that the lower portion 410 is separated from the bayonet 224. Furthermore, the caliber of the V-shaped bayonet 630 is a trapezoid structure with a large outside and a small inside, so that the transmission shafts 420 with different diameters can be clamped in the V-shaped bayonet 630, thereby adapting to the transmission shafts 420 with different diameters.
In one embodiment, as shown in fig. 1, a wire receptacle 232 is disposed under the second jaw 200, and the wire receptacle 232 is adapted to mate with a test wire of an external testing apparatus. To avoid the influence of the test wires on the clamping action of the head portion 210 of the second clip and the stability of the clamping pins 410 clamped to the clamping openings 224, the wire receptacle 232 is preferably disposed below the tail portion 230 of the second clip.
Furthermore, in order to prevent the internal voltage of the test instrument from being transmitted to the tail parts (130,230) of the first clamping piece and the second clamping piece through the test line, thereby threatening the personal safety of operators, the outer sides of the tail parts (130,230) of the first clamping piece and the second clamping piece are provided with insulating sleeves (131, 231). When a user clamps the tail parts (130,230) of the first clamping piece and the second clamping piece to open the head parts (110,210) of the first clamping piece and the second clamping piece, the insulating sleeves (131,231) can isolate the voltage of the first clamping piece 100 and the second clamping piece 200, and the personal safety of the operator is ensured.
When the hand-held telescopic detection device is used for clamping the point 700 to be detected for detection, firstly, the tail portions (130,230) of the first clamping piece and the second clamping piece are manually clamped, the first clamping piece 100 rotates clockwise around the first pin shaft 122 relative to the supporting column 300, the second clamping piece 200 rotates counterclockwise around the second pin shaft 222 relative to the supporting column 300, and the head portions (110,210) of the first clamping piece and the second clamping piece are opened. Then, when the bayonet 224 at the lower end of the second clip 200 is aligned with the sliding slot 330 of the post 300, the spring 430 drives the pin 410 to move in the sliding slot 330 toward the second clip 200 so as to be locked in the bayonet 224, and the pin 410 prevents the first and second clips 100 and 200 from rotating to keep the first and second clip heads (110,210) in an open state. Then, after the matching position of the inner nested pipe and the outer nested pipe of the telescopic rod 600 is adjusted to make the length of the telescopic rod 600 meet the height requirement of the point 700 to be detected, the telescopic rod 600 is connected with the transmission shaft 420 and the detection device is moved to make the point 700 to be detected be located between the first clamping piece 100 and the second clamping piece 200.

The telescopic rod 600 is pulled downwards to separate the telescopic rod 600 from the transmission shaft 420, the clamping operation is repeated, a plurality of detection devices are clamped on the points 700 to be detected, and detection is carried out through an external test instrument.
When the detection device is taken out from the point 700 to be detected after the detection is finished, firstly, the telescopic rod 600 is pushed upwards, the telescopic rod 600 drives the transmission shaft 420 to move towards the direction close to the second clamping piece 200, and the transmission shaft 420 drives the bayonet 410 at the upper end to abut against the lower end of the second clamping piece 200. Then, the telescopic rod 600 is continuously pushed upwards, the bayonet 410 applies pressure to the bottom of the second clamping piece 200 to drive the second clamping piece 200 to rotate anticlockwise relative to the support column 300 around the second pin 222, when the bayonet 224 aligns with the sliding groove 330 of the support column 300, the bayonet 410 is clamped in the bayonet 224 under the pushing of the transmission shaft 420, the heads of the first clamping piece 100 and the second clamping piece 200 are in an open state, and the telescopic rod 600 is moved to take out the detection device from the point 700 to be detected. The above operation is repeated, and the plurality of detection devices are taken out from the point to be detected through one telescopic rod 600.
