Description

Technical Field

[0001] This utility model relates to the field of voltage testing pen technology, specifically a voltage testing pen. Background Technology

[0002] Voltage testers (commonly known as electric testers) are a basic tool for electrical engineering and daily electrical safety testing. Their development is closely related to the popularization of power technology, the increasing demand for electrical safety, and the progress of electronic technology. When using them, the metal probe of the voltage tester is brought into contact with the live conductor for testing.

[0003] However, the metal probe of a voltage tester is usually exposed. If it is not handled properly during use, the metal probe is prone to wear and tear, which affects the normal use of the voltage tester. Furthermore, when storing the voltage tester, the exposed metal probe is prone to bumps and scratches, which is not conducive to the storage of the voltage tester.

[0004] In view of this, we propose a voltage detection pen. Utility Model Content

[0005] The purpose of this invention is to provide a voltage testing pen to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A voltage testing pen includes a pen body, a pen tip connected to one end of the pen body, and a protective sleeve slidably connected to the side wall of the pen body. A pen tip groove is formed at one end of the protective sleeve, and the inner wall of the pen tip groove is slidably connected to the side wall of the protective sleeve. Two limiting grooves are formed on the side wall of the pen body, and a sealing inclined limiting groove and a measuring inclined limiting groove are formed on the bottom surface of the limiting groove. A spring groove is formed on the inner wall of the protective sleeve, and a limiting spring is provided inside the spring groove. An inclined limiting pin is fixedly connected to one end of the limiting spring, and one end of the inclined limiting pin extends out of the spring groove and is slidably connected to the sealing inclined limiting groove.

[0008] When no testing is required, the protective sleeve protects the test pen tip. A limiting spring pushes the inclined limiting pin into the sealed inclined limiting groove, securing the protective sleeve and preventing damage to the test pen tip. When testing is needed, the protective sleeve is pushed upwards. The inclined surface of the limiting pin slides along the inclined surface of the sealed inclined limiting groove, pressing the limiting spring upwards. When the limiting pin moves to one side of the measuring inclined limiting groove, the limiting spring pushes the pin into the groove, securing the protective sleeve. At this point, the test pen tip is exposed, and testing can begin. After testing, the protective sleeve is moved downwards. The limiting pin slides into the sealed inclined limiting groove, securing the protective sleeve. The test pen tip remains inside the protective sleeve, protecting it from damage and ensuring safety and reliability.

[0009] Preferably, a first fixing rod is fixedly connected to the inner wall of the sealing inclined surface limiting groove and the measuring inclined surface limiting groove, and a first rotating sleeve is rotatably connected to the side wall of the first fixing rod;

[0010] By setting up the cooperation between the first fixed rod and the first rotating sleeve, when the protective sleeve needs to be moved, the side wall of the first rotating sleeve will roll along the inclined plane of the inclined plane limit pin, which facilitates pushing the inclined plane limit pin up and improves the smoothness of operation.

[0011] Preferably, the bottom surface of the inclined limiting pin is fixedly connected to a second fixing rod, and the side wall of the second fixing rod is rotatably connected to a second rotating sleeve;

[0012] By setting up a second fixed rod and a second rotating sleeve in cooperation, when the inclined limit pin moves along the surface of the limit slide groove, the second rotating sleeve will roll along the surface of the limit slide groove, reducing friction and facilitating the movement of the protective sleeve. It is simple, reliable and easy to operate.

[0013] Preferably, the side wall of the protective sleeve is fixedly connected to two auxiliary blocks;

[0014] By setting up auxiliary blocks, operators can move the protective cover to expose the test pen tip for testing, or move the protective cover to protect the test pen tip, thus improving operational convenience.

[0015] Preferably, the sidewalls of the auxiliary block are fixedly connected with multiple strip blocks;

[0016] By setting up strip blocks, the roughness of the sidewalls of the auxiliary blocks is increased, friction is increased, and the auxiliary blocks are easier to move.

[0017] Preferably, a sealing rubber sleeve is fixedly connected to the inner wall of the pen tip groove;

[0018] By incorporating a sealing rubber sleeve, the sealing performance is improved, reducing the probability of external dust penetrating the pen tip groove and enhancing the protective strength of the protective sleeve.

[0019] Preferably, the sidewall of the sealing rubber sleeve is provided with a guide slope;

[0020] By setting a guide ramp, the guide ramp provides a guiding function. When the test pen tip moves to one side of the guide ramp, it will slide out along the ramp, improving the ease of operation.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This voltage testing pen, when not in use, has a protective sleeve that encloses the pen tip. A limiting spring pushes a beveled limiting pin into a sealed beveled limiting groove, securing the protective sleeve and preventing damage to the pen tip. When testing is required, the protective sleeve is pushed upwards. The beveled surface of the limiting pin slides along the bevel of the sealed beveled limiting groove, pressing the limiting spring upwards. When the limiting pin moves to one side of the measuring beveled limiting groove, the limiting spring pushes the pin into the groove, securing the protective sleeve. At this point, the pen tip is exposed, allowing testing to proceed. After testing, the protective sleeve is moved downwards, causing the limiting pin to slide into the sealed beveled limiting groove, securing the sleeve. The pen tip remains inside the protective sleeve, protecting it from damage and ensuring safety and reliability. Attached Figure Description

[0031] A voltage testing pen includes a testing pen body 1, a testing pen tip 2 connected to one end of the testing pen body 1, and a protective sleeve 3 slidably connected to the side wall of the testing pen body 1. A pen tip groove 4 is formed at one end of the protective sleeve 3, and the inner wall of the pen tip groove 4 is slidably connected to the side wall of the protective sleeve 3. Two limiting grooves 18 are formed on the side wall of the testing pen body 1, and a sealing inclined limiting groove 5 and a measuring inclined limiting groove 6 are formed on the bottom surface of the limiting grooves 18. A spring groove 7 is formed on the inner wall of the protective sleeve 3, and a limiting spring 8 is provided inside the spring groove 7. An inclined limiting pin 9 is fixedly connected to one end of the limiting spring 8, and one end of the inclined limiting pin 9 extends out of the spring groove 7 and is slidably connected to the sealing inclined limiting groove 5. When testing is not required, the protective sleeve 3 protects the testing pen tip 2, and the limiting spring 8 pushes the inclined limiting pin 9. The protective sleeve 3 is fixed in the sealing inclined groove 5, thus preventing damage to the test pen tip 2. When testing is required, the protective sleeve 3 can be pushed upwards. The inclined surface of the inclined limit pin 9 will slide along the inclined surface of the sealing inclined groove 5, squeezing the limit spring 8 to rise. When the inclined limit pin 9 moves to one side of the measuring inclined groove 6, the limit spring 8 will push the inclined limit pin 9 into the measuring inclined groove 6 to fix the protective sleeve 3. At this time, the test pen tip 2 will be exposed in the protective sleeve 3, and testing can then be carried out. After the test is completed, the protective sleeve 3 is moved downwards. At this time, the inclined limit pin 9 will slide into the sealing inclined groove 5, thus fixing the protective sleeve 3. The test pen tip 2 will be inside the protective sleeve 3, protecting the test pen tip 2 and preventing damage to the test pen tip 2. It is safe and reliable.

[0032] In this embodiment, a first fixing rod 10 is fixedly connected to the inner wall of the sealing inclined limiting groove 5 and the measuring inclined limiting groove 6, and a first rotating sleeve 11 is rotatably connected to the side wall of the first fixing rod 10. By setting the cooperation between the first fixing rod 10 and the first rotating sleeve 11, when the protective sleeve 3 needs to be moved, the side wall of the first rotating sleeve 11 will roll along the inclined surface of the inclined limiting pin 9, which facilitates pushing the inclined limiting pin 9 up and improves the smoothness of operation.

[0033] In this embodiment, a second fixing rod 12 is fixedly connected to the bottom surface of the inclined limiting pin 9, and a second rotating sleeve 13 is rotatably connected to the side wall of the second fixing rod 12. By setting the cooperation of the second fixing rod 12 and the second rotating sleeve 13, when the inclined limiting pin 9 moves along the surface of the limiting slide groove 18, the second rotating sleeve 13 will roll along the surface of the limiting slide groove 18, reducing friction and facilitating the movement of the protective sleeve 3. This is simple, reliable, and easy to operate.

[0034] In this embodiment, two auxiliary blocks 14 are fixedly connected to the side wall of the protective sleeve 3. By setting the auxiliary blocks 14, the auxiliary blocks 14 can assist the operator in moving the protective sleeve 3 to expose the test pen tip 2 for testing, or move the protective sleeve 3 to protect the test pen tip 2, thereby improving the convenience of operation.

[0035] In this embodiment, multiple strip blocks 15 are fixedly connected to the side wall of the auxiliary block 14; by setting the strip blocks 15, the strip blocks 15 will increase the roughness of the side wall of the auxiliary block 14, increase the friction, and facilitate the movement of the auxiliary block 14.

[0036] In this embodiment, a sealing rubber sleeve 16 is fixedly connected to the inner wall of the pen tip groove 4; by setting the sealing rubber sleeve 16, the sealing rubber sleeve 16 will improve the sealing performance, reduce the probability of external dust penetrating the pen tip groove 4, and improve the protective strength of the protective sleeve 3.

[0037] In this embodiment, a guide slope 17 is provided on the side wall of the sealing rubber sleeve 16. By providing the guide slope 17, the guide slope 17 will provide a guiding function. When the test pen tip 2 moves to one side of the guide slope 17, it will slide out along the slope of the guide slope 17, thereby improving the ease of operation.

[0038] In this embodiment, when a voltage testing pen is not in use, the protective sleeve 3 protects the pen tip 2, and the limiting spring 8 pushes the inclined limiting pin 9 into the sealing inclined limiting groove 5, thereby fixing the protective sleeve 3 and preventing damage to the pen tip 2. When testing is required, the protective sleeve 3 can be pushed upwards, and the inclined surface of the inclined limiting pin 9 will slide along the inclined surface of the sealing inclined limiting groove 5, pressing the limiting spring 8 upwards, while the inclined limiting pin 9 moves upwards. When the device moves to one side of the measuring inclined plane limiting groove 6, the limiting spring 8 will push the inclined plane limiting pin 9 into the measuring inclined plane limiting groove 6 to fix the protective sleeve 3. At this time, the protective sleeve 3 will expose the test pen tip 2, and then the testing work can be carried out. After the testing is completed, the protective sleeve 3 is moved downward. At this time, the inclined plane limiting pin 9 will slide into the sealing inclined plane limiting groove 5, thereby fixing the protective sleeve 3. The test pen tip 2 will be inside the protective sleeve 3 to protect the test pen tip 2 and prevent the test pen tip 2 from being damaged, which is safe and reliable.
