[0028] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] like Figures 1 to 6 As shown, this application provides a portable voltage testing pen, comprising:

[0030] The testing pen 100 includes a testing mechanism 10, a power supply mechanism 30, a locking mechanism 40, and a display screen 18. The testing mechanism 10 also includes a main housing 11. A mounting cylinder 12 is integrally formed at the center of the main housing 11. A receiving cavity 13 is formed between the mounting cylinder 12 and the inner wall of the main housing 11. A mounting cavity 14 is provided inside the mounting cylinder 12. A connecting terminal 15 is slidably connected to one side of the mounting cavity 14. A resistor 16 and a main board 17 are fixedly mounted on the other side of the mounting cavity 14. The two ends of the resistor 16 are electrically connected to the connecting terminal 15 and the main board 17 respectively via wires. The display screen 18 is disposed on the outer wall of the main housing 11. The display screen 18 is electrically connected to the motherboard 17; the storage mechanism 20 is threadedly connected to one side of the detection mechanism 10. The storage mechanism 20 also includes a front cover 21. A sleeve 22 adapted to the mounting cylinder 12 is integrally provided on one side of the front cover 21. Multiple equally spaced partitions 24 are fixedly installed on the outer wall of the sleeve 22. Two adjacent partitions 24 and the sleeve 22 form a fixing part 25. A locking block 26 is fixedly installed on one side of the sleeve 22 inside the fixing part 25. A detection pen 27 is provided inside the multiple locking blocks 26. An insertion hole 23 is opened on one side of the front cover 21. The insertion hole 23 is connected to the sleeve 22.

[0031] By adopting the above technical solution, a sleeve 22 and a partition 24 are provided on one side of the front cover 21, forming a fixing part 25 between the sleeve 22 and the partition 24. A locking block 26 is then provided inside the fixing part 25 to fix the detection pen 27 with different ends inside the fixing part 25. This facilitates the storage of the detection pen 27 and allows multiple detection pen 27s with different ends to be carried at once. At the same time, by providing a storage cavity 13 inside the main housing 11, the sleeve 22 and the external detection pen 27 are stored in the storage cavity 13, which greatly reduces the overall size of the test pen and makes it easy to carry. Meanwhile, the detection pen 27 inside the test pen is not exposed, which prevents the detection pen 27 from accidentally injuring the human body and protects the detection pen 27.

[0032] It should be noted that when the test pen is needed, the front cover 21 is unscrewed from the front of the main housing 11. The corresponding test pen rod 27 is retrieved from the multiple fixing parts 25 according to the different detection targets. The rear side of the test pen rod 27 is inserted into the mounting cavity 14 through the insertion hole 23. When the test pen rod 27 enters the mounting cavity 14 and contacts the connecting terminal 15, the end slot of the locking block 42 contacts the vertical part of the locking boss 41, thereby fixing the position of the test pen rod 27. After the test pen rod 27 is fixed, the front side of the test pen rod 27 is inserted into the required detection area. Current flows through the test pen rod 27, through the connecting terminal 15, the resistor 16, and finally to the main board 17. The main board 17 calculates the voltage and displays it on the display screen 18. When the test pen needs to be stored, the test pen rod 27 is pushed inward. The test pen rod 27 moves to the right along the inner wall of the mounting cavity 14 under force. During this process, the upper wall of the test pen rod 27... The push boss 44 pushes the slider 45 to move to the right along the slide groove 43, causing the limiting protrusion 47 at the end of the slider 45 to press against the left side of the locking block 42 and enter the limiting hole 46 on the upper left side of the locking block 42, thereby causing the right side of the locking block 42 to lift up and be fixed. At this time, the locking block 42 is no longer in contact with the locking boss 41, and the detection pen 27 is unlocked from the locking block 42. The locking boss 41 is pulled outward to push the slider 45 to reset on one side, thereby causing the limiting protrusion 47 at the end of the slider 45 to move out of the limiting hole 46. At this time, the locking block 42 is reset by the rebound force of the second spring 48. When the slider 45 moves to the leftmost side of the slide groove 43, the detection pen 27 is rotated so that the locking boss 41 is no longer in contact with the outer wall of the slider 45, thereby pulling out the detection pen 27. After the detection pen 27 is pulled out, it is fixed inside the fixing part 25 by the locking block 26, and then the sleeve 22 is inserted into the storage cavity 13 to realize the storage of the test pen.

[0033] In an optional embodiment, the locking mechanism 40 includes a locking boss 41 disposed at one end of the outer wall of the detection pen 27, a pushing boss 44 disposed at the other end of the outer wall of the detection pen 27, a sliding groove 43 formed on one side of the upper wall of the mounting cylinder 12, and a locking block 42 hinged to one side of the upper wall of the mounting cylinder 12. A slider 45 is slidably connected inside the sliding groove 43. A limiting protrusion 47 is integrally provided on the right side of the slider 45. A limiting hole 46 adapted to the limiting protrusion 47 is provided on the upper wall of the locking block 42 near the slider 45, and a slot adapted to the locking boss 41 is provided on the other side. When the detection pen 27 is installed, the slot at the end of the locking block 42 contacts the vertical part of the locking boss 41 on the upper wall of the detection pen 27, thereby fixing the position of the detection pen 27. When the detection pen 27 is pulled out, the detection pen 27 is pushed inward, and the detection pen 27 is subjected to force along the mounting cylinder 12. The inner wall of cavity 14 moves to the right. During this process, the push boss 44 on the upper wall of the detection pen 27 pushes the slider 45 to move to the right along the slide groove 43, so that the limiting protrusion 47 at the end of the slider 45 presses against the left side of the locking block 42 and enters the limiting hole 46 on the upper left side of the locking block 42, thereby causing the right side of the locking block 42 to lift up and be fixed. At this time, the locking block 42 is no longer in contact with the locking boss 41. At this time, the detection pen 27 and the locking block 42 are unlocked. Continue to pull the locking boss 41 outward so that one side pushes the slider 45 to reset, thereby causing the limiting protrusion 47 at the end of the slider 45 to move out of the limiting hole 46. At this time, the locking block 42 is reset by the rebound force of the second spring 48. When the slider 45 moves to the leftmost side of the slide groove 43, the detection pen 27 is rotated so that the locking boss 41 is no longer in contact with the outer wall of the slider 45, thereby realizing the removal of the detection pen 27, which is convenient for installation and disassembly.

[0034] In an optional embodiment, a second spring 48 is fixedly installed between the locking block 42 and the upper wall of the mounting cylinder 12, so that the locking block 42 can be automatically reset by setting the second spring 48.

[0035] In an optional embodiment, a spring 110 is fixedly installed between the connecting terminal 15 and the inner wall of the mounting cylinder 12, and the connecting terminal 15 can be automatically reset by the spring 110.

[0036] In an optional embodiment, the power supply mechanism 30 is threadedly connected to the right side of the detection mechanism 10. The power supply mechanism 30 also includes a rear end cover 31. A battery 32 is provided inside the rear end cover 31. The rear end cover 31 is used to protect one end of the main housing 11, and the battery 32 is used to supply power to the device.

[0037] In an optional embodiment, a hanging rod 19 is fixedly installed on one side of the outer wall of the main housing 11, and the device can be fixed at the bag opening by setting the hanging rod 19.

[0038] In one optional implementation, the motherboard 17 is electrically connected to the battery 32 and the display screen 18. The battery 32 supplies power to the motherboard 17, and the data calculated by the battery 32 is displayed on the motherboard 17 to achieve automatic voltage measurement.

[0039] In one optional embodiment, the outer wall of the main housing 11 is provided with a plurality of process grooves, which improve the friction of the outer wall of the main housing 11 and enhance its anti-slip properties.

[0040] In an optional embodiment, a groove is provided on the side of the locking boss 41 near the locking block 42, and a protrusion adapted to the groove is provided on the side of the locking block 42 near the locking boss 41. When 41 and 42 are in the locked state, the protrusion enters the groove, which can prevent 41 from disengaging from 42 by rotation.
