The utility model is provided with a protective piece, which is conducive to protecting the test leads, so that they can be removed when in use and automatically restored when not in use, thereby increasing safety. and portability.

(2) Technical solutions

In order to solve the above problems, the present utility model provides a fault detection device, which includes a multimeter body and test leads connected to the multimeter body, and the test leads are provided with protective parts;

When in use, the protective piece has a first state and a second state;

The first state is when the protective piece is located at the tip of the test pen;

The second state is when the protective member releases the protection of the tip of the test pen.

Preferably, the protective member includes a sleeve, a limiting ring and a spring. The limiting ring is fixedly mounted on the test lead, the sleeve is located on the outer periphery of the test lead tip, and the spring is movably sleeved on the outer periphery of the test lead. One end of the spring is fixedly connected to the limiting ring, and the other end of the spring is fixedly connected to the inner wall of the casing.

Preferably, one end of the sleeve away from the limiting ring is closed, and the closed end forms a through hole for the test leads to pass through.

Preferably, the outer periphery of the sleeve is fixed with a toggle ring.

Preferably, plug-in shafts are fixedly installed on both sides of the multimeter body, and the toggle ring is provided with a plug-in hole adapted to the plug-in shaft.

Preferably, the main body of the multimeter is provided with a magic band.

The above technical solution of the present invention has the following beneficial technical effects:

Under the action of the sleeve, it plays a role in protecting the tip of the test pen. By turning the toggle ring along the length of the test pen, the toggle ring drives the sleeve to move. At this time, the spring is compressed to relieve the pressure of the sleeve. The protection of the nib of the test pen is achieved, thus achieving the effect of easily releasing the protection. When the toggle ring is released, the compressed spring returns, driving the sleeve to return, so that the sleeve protects the nib of the test pen, thus achieving the effect of facilitating the release of the protection. Protection effect; inserting the toggle ring on the insertion shaft facilitates the placement of the test leads and facilitates the portability of the entire detection device.

Detailed ways

In order to make the purpose, technical solutions and advantages of the present utility model clearer, the utility model will be further described in detail below with reference to the specific embodiments and the accompanying drawings. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention. Furthermore, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily confusing the concepts of the present invention.

As shown in Figure 1-2, a fault detection device proposed by the utility model includes a multimeter body 1 and a test lead 2 connected to the multimeter body 1. The test lead 2 is provided with a protective piece;

When in use, the protective piece has a first state and a second state;

The first state is that the protective piece is located at the tip of test lead 2;

The second state is when the protective member releases the protection of the nib of the test pen 2.

In an optional embodiment, in order to protect the pen tip of the test lead 2 to reduce accidental touch damage, the protective component includes a sleeve 3, a limit ring 4 and a spring 5. The limit ring 4 is fixedly mounted on the test lead 2 , the sleeve 3 is located on the outer periphery of the tip of the test lead 2, the spring 5 is movably connected to the outer periphery of the test lead 2, one end of the spring 5 is fixedly connected to the limiting ring 4, and the other end of the spring 5 is fixedly connected to the inner wall of the sleeve 3.

It should be noted that moving the sleeve 3 along the length direction of the test lead 2 causes the limit ring 4 to continuously increase the depth inside the sleeve 3 and compress the spring 5. The compressed spring 5 has resilience to facilitate Drive casing 3 to reply.

In an optional embodiment, one end of the sleeve 3 away from the limiting ring 4 is closed, and the closed end forms a through hole for the test lead 2 to pass through.

It should be noted that the head of the test lead 2 can be moved out of the sleeve 3 .

In an optional embodiment, a toggle ring 6 is fixedly mounted on the outer periphery of the sleeve 3 .

It should be noted that the toggle ring 6 can be used to drive the sleeve 3 to move along the length direction of the test lead 2 .

In an optional embodiment, plug-in shafts 7 are fixedly installed on both sides of the multimeter body 1 , and the toggle ring 6 is provided with a socket that matches the plug-in shaft 7 .

It should be noted that inserting the plug shaft 7 into the inside of the jack has the effect of limiting the position of the test lead 2 .

In an optional embodiment, the multimeter body 1 is provided with a magic band (not shown).

It should be noted that under the action of the magic belt, the main body 1 of the multimeter can be tied to the arm to increase the effect of facilitating observation during use.

In the present utility model, under the action of the sleeve 3, it plays a role in protecting the tip of the test lead 2. By moving the toggle ring 6 along the length direction of the test lead 2, the toggle ring 6 drives the sleeve 3 to move. When the spring 5 is compressed, the protection of the tip of the test pen 2 by the sleeve 3 is released, thereby achieving the effect of easily releasing the protection. When the toggle ring 6 is released, the compressed spring 5 returns and drives the sleeve 3 is restored, so that the sleeve 3 protects the tip of the test lead 2, thereby achieving the effect of convenient protection; inserting the toggle ring 6 on the insertion shaft 7 serves to facilitate the placement of the test lead 2, so as to facilitate the placement of the test lead 2. The entire detection device is carried.
