Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electric test pens, and more specifically relates to a bendable multifunctional electric test pen. Background Art
[0002] A voltage tester, also known as a test pencil or electrician's pencil, is an electrical tool used to detect whether a wire is live. The basic principle is to detect whether a wire is live by contacting it with a live object and then using the internal neon bulb (also called a neon tube) to illuminate in response to an electrical signal.
[0003] Current test pens have limited functionality and can't be bent, making it difficult to measure objects around corners. The straight design of the tester makes it difficult to make subtle adjustments to charged objects or access tight spaces, significantly reducing ease and accuracy. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a bendable multifunctional electrical tester, which has the advantages of improving its adaptability and efficiency in various working environments.
[0005] To achieve the above objectives, the present invention provides the following technical solutions:
[0006] A bendable multifunctional electrical tester comprises a pen holder and a pen tip, wherein the pen tip comprises a first pen segment, a second pen segment, and a third pen segment. An end of the second pen segment close to the third pen segment is provided with a first notch portion, the first notch portion being rotatably connected to a first connecting rod, and a circular hole being provided in the middle of the first connecting rod.
[0007] The end of the pen segment 3 close to the pen segment 2 is provided with a notch portion 2, and the notch portion 2 is provided with a connecting rod 2 adapted to the circular hole 2, and the connecting rod 2 is rotatably connected to the circular hole.
[0008] The advantages of this solution include: when using the tester, the second and third segments can be flexed to meet corners and other situations through the rotatable connection between them. This allows the tip of the tester to bend, making it easier to test in narrow or hard-to-reach areas, thus improving flexibility and convenience. This prevents the tester from accidentally contacting live parts during operation, thereby reducing the risk of electric shock. It also improves operational flexibility and convenience, while also enhancing safety and stability.
[0009] The utility model is further configured as follows: the pen section 1 is composed of carbon fiber high-toughness insulating material.
[0010] The advantages of this solution are at least that the carbon fiber high-toughness insulating material is tough and bendable, which enables the tip of the pen to be better bent in narrow and curved areas, thereby improving the applicability of the test pencil in different environments.
[0011] The utility model is further configured as follows: a return spring is sleeved on an outer peripheral wall of the pen section.
[0012] The advantage of this solution is that, by providing a return spring, the pen section can return to its original shape after the external force is removed when it is deformed, thereby improving the bending bearing capacity and return ability and possible constant return force.
[0013] The utility model is further configured as follows: the first pen segment and the second pen segment are rotatably connected.
[0014] This solution offers at least one advantage: when measuring voltage at different locations, rotating the first segment to adjust the contact point ensures precise contact between the test pencil and the target conductor, improving measurement accuracy. This reduces wear and damage caused by fixed contact, extending the test pencil's service life and reducing maintenance costs.
[0015] The utility model is further configured as follows: a plurality of compression springs are provided on the end surfaces of the second and third pen segments that are close to each other.
[0016] The advantage of this solution is at least that: by providing a compression spring, the compression spring has a reset capability, thereby ensuring that the pen section three is reset to its original position, thereby ensuring accuracy and stability.
[0017] The utility model is further configured as follows: a plurality of lighting lamps are provided on the end surface of one side of the pen section 1 close to the pen section 2.
[0018] The advantage of this solution is at least that by setting up a lighting lamp, when in a dimly lit environment, the lighting lamp can illuminate the measured point, allowing the user to more clearly see whether the conductor is in contact and whether there is voltage, which not only improves the safety of operation but also increases the convenience of use.
[0019] In summary, the present invention has at least the following advantages:
[0020] 1. By setting a return spring, the pen section can return to its original shape after the external force is removed when it is deformed under the action of external force. This improves the bending bearing capacity and return ability as well as the possible constant return force;
[0021] 2. By setting a compression spring, the compression spring has the ability to reset, ensuring that the pen section 3 is reset to its original position, ensuring accuracy and stability;
[0022] 3. By setting up a lighting lamp, when in a dark environment, the lighting lamp can illuminate the measured point, allowing the user to more clearly see whether the conductor is touched and whether there is voltage, which not only improves the safety of operation, but also increases the convenience of use.

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.
[0029] A bendable multifunctional test pencil, such as Figure 1 and Figure 2 As shown, it includes a pen body 1 and a pen tip 2. The pen tip 2 includes a pen segment 1 3, a pen segment 2 4 and a pen segment 3 5. The pen segment 2 4 has a notch 1 6 at one end near the pen segment 3 5. A connecting rod 1 7 is rotatably connected in the notch 1 6. The connecting rod 1 7 has a circular hole in the middle.
[0030] The end of the pen segment 3 5 near the pen segment 2 4 is provided with a notch 2 8, and a connecting rod 2 9 adapted to the circular hole 2 is provided in the notch 2 8, and the connecting rod 2 9 is rotatably connected to the circular hole. When using the test pen of the present invention, when encountering corners, the rotational connection between the pen segment 2 4 and the pen segment 3 5 can be coordinated to achieve a bendable effect, so that the tip 2 can achieve bendability measurement, making it easier to test the test pen in small or hard-to-reach areas, thereby improving the flexibility and convenience of use. Not only can it prevent the test pen from accidentally touching other live parts during operation, thereby reducing the risk of electric shock, but it also improves the flexibility and convenience of operation, and enhances safety and stability.
[0031] The pen section 1 3 is made of carbon fiber high-toughness insulation material. The carbon fiber high-toughness insulation material is tough and bendable, which enables the pen tip 2 to bend better in narrow and curved areas, improving the applicability of the test pencil in different environments.
[0032] like Figure 3 As shown, the outer wall of pen segment 13 is sheathed with a return spring 10. The provision of return spring 10 enables pen segment 13 to return to its original shape after the external force is removed when it is deformed. This improves the bending resistance and return capability, as well as the possibility of a constant return force.
[0033] Segment 1 3 and segment 2 4 are rotatably connected. When measuring voltage at different locations, rotating segment 1 3 adjusts the contact point, ensuring precise contact between the test pencil and the target conductor, improving measurement accuracy. This reduces wear and damage caused by fixed contact, extending the test pencil's service life and reducing maintenance costs.
[0034] like Figure 2 As shown, the end faces of one side of the pen segment 2 4 and the pen segment 3 5 that are close to each other are both provided with a plurality of compression springs 11. By providing the compression springs 11, the compression springs 11 have a reset capability, ensuring that the pen segment 3 5 is reset to its original position, ensuring accuracy and stability.
[0035] like Figure 4 As shown, a plurality of lights 12 are provided on the end surface of the pen segment 1 3 near the pen segment 2 4. By providing the lights 12, when in a dimly lit environment, the lights 12 can illuminate the test point, allowing the user to more clearly see whether the conductor is in contact and whether there is voltage, which not only improves the safety of operation but also increases the convenience of use.
[0036] The working process and beneficial effects of the present invention are as follows: When using the tester, the second and third segments 4 and 5 can be flexed to meet corners and other requirements by means of the rotational connection. This allows the tip 2 to bend and measure the bendability of the tester, making it easier to test in confined or hard-to-reach areas, thereby improving the flexibility and convenience of use. This prevents the tester from accidentally contacting other live parts during operation, thereby reducing the risk of electric shock. Furthermore, the tester improves operational flexibility and convenience, while also enhancing safety and stability.
[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
