Description

Technical Field

[0001] This utility model relates to the field of power system testing technology, specifically a power supply line testing device. Background Technology

[0002] Existing circuit testing technology is relatively mature, and there are various testing instruments on the market. The most commonly used and widely adopted is the handheld circuit tester, such as the MS8211 model circuit diagnostic instrument. This instrument is lightweight and convenient. When using it, you only need to hold it in your hand, connect the positive and negative polarity test leads to the diagnostic instrument, clamp the circuit with the clip at the other end of the lead, start the diagnostic instrument, and perform debugging operations to perform the test.

[0003] During the use of existing diagnostic instruments, for ease of storage, staff will wrap the positive and negative wires around the instrument's casing and put the wrapped instrument into a toolbox or bag. Since circuit engineers use a lot of tools in their toolboxes or bags, and need to carry the bags to change circuit test points during circuit testing, other tools inside the toolbox will collide and rub against the wrapped wires. In severe cases, this can cause the wires to break, the clips to be flattened and damaged, affecting subsequent normal use.

[0004] Therefore, we propose a power supply line detection device. Utility Model Content

[0005] One of the technical problems this utility model aims to solve is that, during the use of existing diagnostic instruments, in order to facilitate storage, staff will wrap the positive and negative wires around the instrument's casing. Since circuit engineers have many tools in their toolboxes or bags, other tools inside will collide and rub against the wrapped wires, which can lead to wire breakage and clip flattening and damage, affecting subsequent normal use.

[0006] To solve the above-mentioned technical problems, this utility model provides a power line testing device, including a diagnostic instrument body, and further including: a wire fixing mechanism, the wire fixing mechanism including a first fixing plate disposed on the side of the diagnostic instrument body, a wire winding plate disposed on the first fixing plate, and a second fixing plate disposed on the side of the wire winding plate away from the first fixing plate, the wire fixing mechanism being used to wind the wire; and a protective mechanism, the protective mechanism including a protective shell disposed on the second fixing plate, the protective shell covering the outside of the wire winding plate, and both ends of the protective shell being longer than the wire winding plate, the protective shell being used for limiting protection.

[0007] In some embodiments, two symmetrical storage openings are provided at one end of the winding plate, and symmetrically distributed elastic sheets are provided on the inner wall of the storage openings.

[0008] In some embodiments, the outer surface of the second fixing plate is provided with a mounting slide rail, and the inner wall of the protective shell is provided with a T-shaped mounting rod that slides and matches the mounting slide rail.

[0009] In some embodiments, the second fixing plate is provided with a limiting groove near the insertion end of the mounting slide rail; a support plate is provided on the protective shell near the limiting groove, and a limiting member is also provided. The limiting member includes a damping shaft provided on the support plate and a limiting plate rotatably connected to the damping shaft. The limiting plate can be rotated into the limiting groove, and a protruding plate is also provided on the limiting plate.

[0010] In some embodiments, protective sponges are disposed on the two inner walls of the protective shell that are symmetrical to each other, and the two protective sponges are respectively located on the corresponding side of the winding plate.

[0011] In some embodiments, multiple uniformly arranged anti-slip stripes are provided on the outer surfaces of the two symmetrical side walls of the protective shell.

[0012] In some embodiments, a chamfer is provided on the insertion end of the T-shaped mounting rod.

[0013] In some embodiments, a bevel is provided at the insertion end of the mounting slide rail.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. By setting up a wire-fixing mechanism, a wire-winding plate is set on the outer shell of the diagnostic instrument for winding the wire. When the wire is retrieved, the wire is wound around the wire-winding plate. Through the set protective mechanism, the protective shell is installed on the second fixing plate and looped around the outside of the wire. This makes the wire not only easy to store, but also has the function of external protection, reducing external collisions and wear, and lowering the probability of damage.

[0016] 2. The detection device has a simple structure and is easy to use. It not only facilitates the storage of wires but also makes it easier to protect them, thus improving its practicality. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figures 1 to 5 The technical solution provided by this utility model is as follows: A power supply line testing device includes a diagnostic instrument body 1, and further includes: a wire fixing mechanism 2, which includes a first fixing plate 4 disposed on the side of the diagnostic instrument body 1, a wire winding plate 5 disposed on the first fixing plate 4, and a second fixing plate 7 disposed on the side of the wire winding plate 5 away from the first fixing plate 4. The first fixing plate 4, the wire winding plate 5 and the second fixing plate 7 are a continuous and connected integral structure, and are fixed to the side of the diagnostic instrument body 1 by pins. The wire fixing mechanism 2 is used to wind the wire; a protective mechanism 3, which includes a protective shell 6 disposed on the second fixing plate 7. On the outer surface of the two symmetrical side walls of the protective shell 6, there are multiple uniformly arranged anti-slip stripes 19. The protective shell 6 covers the outside of the wire winding plate 5, and both ends of the protective shell 6 are longer than the wire winding plate 5. The protective shell 6 is used for limiting protection, and both ends of the wire winding plate 5 are provided with rounded corners.

[0027] In this embodiment, as Figure 1 and Figure 2As shown, two storage openings 8 are symmetrically opened at one end of the winding plate 5. On the inner wall of the storage opening 8, there are symmetrically distributed elastic pieces 9. The elastic pieces 9 can hold the wire connector head through the characteristic clip. When winding and storing, the connector head on the wire is first locked in the storage opening 8. At this time, one end of the wire is fixed. Then, the remaining wire can be wound on the winding plate 5.

[0028] In this embodiment, as Figure 2 and Figure 3 As shown, the outer surface of the second fixing plate 7 is provided with a mounting slide rail 11, and the inner wall of the protective shell 6 is provided with a T-shaped mounting rod 12 that slides and matches the mounting slide rail 11. This arrangement facilitates quick disassembly and assembly of the protective shell 6, so as to facilitate the recycling of the detection device after use.

[0029] The second fixing plate 7 is equipped with a limiting groove 16 near the insertion end of the mounting slide rail 11. On the protective shell 6, a support plate 14 is provided near the limiting groove 16, and a limiting member 13 is also provided. The limiting member 13 includes a damping shaft 18 provided on the support plate 14 and a limiting plate 15 rotatably connected to the damping shaft 18. The limiting plate 15 can rotate into the limiting groove 16. A protruding plate 17 is also provided on the limiting plate 15. Through the damping of the damping shaft 18 and the friction between the limiting plate 15 and the wall of the limiting groove 16, the limiting plate 15 can have high stability and will not rotate due to collision or bump force, thereby playing a stable limiting and protective function.

[0030] In this embodiment, as Figure 2 , Figure 4 and Figure 5 As shown, protective sponges 10 are respectively arranged on the two symmetrical inner walls of the protective shell 6, and the two protective sponges 10 are respectively located on the corresponding side of the winding plate 5. When the protective shell 6 is installed and fixed, the two protective sponges 10 are respectively connected to one side of the wound wire, and the wire can squeeze the protective sponge 10 to deform it, thereby improving the stability of the wire after winding and improving the protective effect.

[0031] In this embodiment, as Figure 4 and Figure 5 As shown, a chamfer 20 is provided on the insertion end of the T-shaped mounting rod 12. The chamfer 20 helps to reduce friction and facilitates the mating installation of the T-shaped mounting rod 12.

[0032] Example 2: Please refer to Figure 6 and Figure 7 The technical solution provided by this utility model is as follows:

[0033] Unlike Embodiment 1, a bevel 21 is provided at the insertion end of the mounting slide rail 11. The bevel 21 expands the insertion range, allowing the T-shaped mounting rod 12 to slide from the bevel 21 into the slide rail groove, reducing friction and facilitating the docking of the T-shaped mounting rod 12 with the mounting slide rail 11, reducing installation difficulty, and preventing damage caused by misoperation during installation.
