[0023] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] Embodiment 1
[0025] In one embodiment, as Figures 1-5As shown in the figure, a small current sampling detection device that is convenient to carry includes a housing 1. On the surface of the housing 1, there is a dial 2 for displaying voltage. On the surface of the housing 1, there is a display screen 3 for recording sampling data. On the surface of the housing 1 corresponding to the display screen 3, there are control buttons 4. On the adjacent surface of the housing 1 and the display screen 3, there is a storage and protection mechanism 5. Inside the storage mechanism, there is a connection line 6 for transmitting current data. The other end of the connection line 6 is provided with a grip block 7. The outer surface of the grip block 7 is covered with an anti-electric rubber coating. The rubber anti-electric coating prevents the detection personnel from getting electrocuted and injured during the current detection process. Inside the grip block 7, there is a telescopic mechanism 8. The other end of the telescopic mechanism 8 is provided with a connection block 10. On the surface of the connection block 10 opposite to the telescopic mechanism 8, there is a detection head 11. On the outer surface of the housing 1, there is a warning light 13 fixedly connected. When there is a leakage at the detection part, the warning light 13 will flash to warn the detection personnel, effectively reducing the probability of the detection personnel getting electrocuted. On the surface of the housing 1 corresponding to the storage and protection mechanism 5, there are several speaker holes 14. When there is a leakage at the detection part, a sharp warning sound will be emitted from the speaker holes 14 to remind the detection personnel.
[0026] In one embodiment, as Figure 2 shown, the storage and protection mechanism 5 includes a storage cavity 51 opened on the adjacent surface of the housing 1 and the display screen 3. On both side surfaces inside the storage cavity 51, there are sliding grooves 52. Inside the sliding grooves 52, there are sliding rods 53. On the inner wall of the storage cavity 51 adjacent to the sliding grooves 52, there are limit openings 54. On the outer surface of the sliding rod 53, there is a cover plate 55. On the outer surface of the cover plate 55, there are anti-slip protrusions 12, which are convenient for the user to open the cover plate 55. The cover plate 55 is slidably connected inside the limit opening 54. When the detection personnel need to carry the detection device, they can open and pull the cover plate 55. At this time, the sliding rod 53 slides in the sliding groove 52, and the grip block 7 and the front detection head are received into the storage cavity 51, and then the cover plate 55 is closed to prevent the detection components from being damaged during transportation and carrying, resulting in the failure of the device.
[0027] Embodiment 2
[0028] In one embodiment, as Figure 3As shown, the telescopic mechanism 8 includes a telescopic groove 81 formed inside the holding block 7. A telescopic slider 82 is slidably connected in the telescopic groove 81. One end of the holding mechanism close to the connecting block 10 is provided with a first notch 83. The size of the first notch 83 is smaller than that of the telescopic slider 82. A fixed block 84 is fixedly connected to the surface of the telescopic slider 82. The fixed block 84 slides inside the first notch 83. The other end of the fixed block 84 is fixedly connected to the outer surface of the connecting block 10. A number of locking mechanisms 9 are provided around the surface of one end of the holding block 7 close to the connecting block 10. When the detection personnel hold the holding block 7 during the measurement process and the detection head 11 cannot measure the target to be detected due to insufficient length, the connecting block 10 can be pulled. At this time, the telescopic slider 82 slides in the telescopic groove 81 and extends out of the telescopic groove 81 through the fixed block 84, increasing the overall measurement length. It can increase the measurement length when measuring the object inside a narrow space, making it more practical.
[0029] In one embodiment, as Figure 4 and Figure 5 shown, the locking mechanism 9 includes a second notch 91 formed on the outer surface of the holding block 7. A locking groove 92 is correspondingly arranged for the second notch 91. A locking block 93 is slidably connected inside the locking groove 92. A number of third notches 94 are formed on the outer side surface of the locking block 93. A number of inner grooves 95 are correspondingly arranged for the third notches 94. A spring 96 is arranged at the bottom end inside the inner groove 95. The other end of the spring 96 is fixedly connected with a locking ball 97. The diameter of the locking ball 97 is smaller than that of the third notch 94. A groove 98 is arranged inside the locking groove 92. The size of the groove 98 is the same as that of the locking ball 97. A locking rod 99 is fixedly connected to the outer surface of the locking block 93. The locking rod 99 is slidably connected inside the second notch 91. The other end of the locking rod 99 is fixedly connected to the surrounding positions of the connection surface between the connecting block 10 and the locking mechanism 9. When the overall measurement length is increased, in order to ensure the safety and stability of the measurement, it is necessary to fix the elongated detector to prevent the telescopic slider 82 from retracting in the telescopic groove 81, resulting in measurement failure. When the measuring device is elongated, the spring 96 is in a compressed state. When the measuring device is elongated to the required length, at this time the locking ball 97 enters the groove 98, and at this time the spring 96 resets to achieve the fixing effect. When the measurement is completed and the measuring device needs to be restored, the measurement personnel only need to push the locking ball 97 out of the groove 98 with force to make the spring 96 in a compressed state again, realizing the restoration of the measuring device, increasing the safety and practicality of the measuring device.
[0030] The above embodiments disclose a small current sampling detection device that is convenient to carry. Among them, when encountering a narrow space during the measurement process, if the detection personnel hold the holding block 7 and the detection head 11 cannot measure the target to be detected due to insufficient length, the connection block 10 can be pulled. At this time, the telescopic slider 82 slides in the telescopic groove 81, and extends out of the telescopic groove 81 through the fixing block 84, increasing the overall measurement length. When it is necessary to measure the object inside a narrow space, the measurement length can be increased, making it more practical. When the overall measurement length is increased, in order to ensure the safety and stability of the measurement, it is necessary to fix the extended detector to prevent the telescopic slider 82 from retracting in the telescopic groove 81, resulting in measurement failure. When the measurer is extended, the spring 96 is in a compressed state. When the measurer is extended to the required length, at this time, the locking ball 97 enters the groove 98, and the spring 96 is reset to achieve the fixing effect. When the measurement is completed and the measurer needs to be restored, the measurer only needs to push the locking ball 97 out of the groove 98 with force, so that the spring 96 is in a compressed state again, realizing the restoration of the measurer, increasing the safety and practicality of the measurer. After the measurement is completed, the measurer can be stored. When the detection personnel need to carry the detection device, the sealing cover plate 55 can be opened and pulled. At this time, the sliding rod 53 slides in the sliding groove 52, and the holding block 7 and the detection head at the front end are stored in the storage cavity 51, and then the sealing cover plate 55 is closed to prevent the detection components from being damaged during transportation and carrying, resulting in equipment failure, and increasing the service life of the equipment.
[0031] As described above, the above are only specific embodiments of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present disclosure can easily think of changes or substitutions, which should be covered by the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claims.
