Description

Technical Field

[0001] This utility model relates to the field of electrical and electronic technology, specifically to an easy-to-use electrical and electronic inspection pen. Background Technology

[0002] An electrical test pen is an electrical tool used to test whether a wire is live. The pen contains a neon bulb; if the bulb lights up during testing, it indicates that the wire is live or is a live wire. The pen tip and tail are made of metal, while the barrel is made of insulating material. Its pen-shaped handle design is ergonomic, improving comfort and allowing for easy tightening or loosening of screws. However, existing easy-to-use electrical test pens have drawbacks. In confined spaces, the worker's hand is limited, preventing the pen from being inserted for testing, thus hindering its use. Furthermore, the pen tip (test head) is difficult to disassemble and reassemble, preventing the replacement of different tip models. Therefore, this invention addresses these issues through in-depth research. Utility Model Content

[0003] This utility model provides an easy-to-use electrical and electronic repair pen, aiming to solve the problems of inconvenience in use and disassembly of the currently used easy-to-use electrical and electronic repair pens.

[0005] Preferably, the disassembly and assembly mechanism includes: a damper fixedly installed on the inner wall of one side of the mounting block, and a first return spring installed on the outer wall of one end of the damper; a locking block connected to one end of the damper, and a locking hole that cooperates with the locking block is provided on the inner wall of one side of the mounting groove.

[0006] Preferably, a pressure rod is movably installed inside the lock hole, a second return spring is installed on the outer side of one end of the pressure rod, and a pressure plate is connected to one end of the pressure rod.

[0007] Preferably, a positioning plate is fixedly installed on the outer wall of one side of the mounting block, and a positioning groove that mates with the positioning plate is provided on the inner wall of the other side of the mounting groove.

[0008] Preferably, a first magnetic ring is embedded in the top of the detection head, and a second magnetic ring is embedded in the bottom of the inspection pen body, wherein the magnetic poles of the second magnetic ring and the first magnetic ring are opposite.

[0009] Preferably, the elongation mechanism includes: a threaded rod installed inside the body of the inspection pen, the top end of which is connected to a top plate; and a rotating ring threaded onto the outer side above the threaded rod.

[0010] Preferably, a limiting groove is provided at the top of the inspection pen body, and limiting blocks that cooperate with the limiting groove are connected to both sides below the rotating ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) By rotating the rotating ring, and while rotating the rotating ring, the limiting block moves in the limiting groove at the same time to achieve the function of limiting the rotating ring. Then, by rotating the ring and threaded rod in threaded engagement, the threaded rod moves upward. After the threaded rod moves out of the inspection pen body, the length of the inspection pen body is extended, which facilitates the use of the inspection pen body.

[0013] (2) The positioning plate at one end of the detection head is inserted into the positioning groove of the mounting groove, and the mounting block is inserted into the mounting groove for positioning. At the same time, the first magnetic ring and the second magnetic ring are magnetically connected to achieve quick positioning and fixation of the detection head and the inspection pen body. When the mounting block of the detection head is installed into the mounting groove, the locking block is squeezed inward as it enters, and the damper and the first return spring are squeezed and deformed. When it enters and passes through the lock hole, the damper and the first return spring reset, causing the locking block to move outward and lock into the lock hole. By pressing the pressure plate inward, the pressure plate drives the pressure rod to squeeze the locking block inward at the same time, so that the locking block is squeezed out of the lock hole. Then the detection head can be pulled out and removed, which facilitates the disassembly and assembly of the detection head. Attached Figure Description

[0022] Example 1

[0023] A preferred embodiment of the easy-to-use electrical and electronic inspection pen provided by this utility model is, for example... Figure 1 and Figure 3 As shown: A user-friendly electrical and electronic repair pen includes: a repair pen body 2; an anti-slip sleeve 1 installed on the outer wall of the repair pen body 2; a detection head 3 connected to the bottom end of the repair pen body 2; a mounting block 10 connected to the top end of the detection head 3; and a mounting groove 11 provided at the bottom end of the repair pen body 2 to cooperate with the mounting block 10; a disassembly and assembly mechanism 5 installed on the inner wall of one side of the mounting block 10, which is used to disassemble and assemble the detection head 3; and an extension mechanism 4 installed on the inner side above the repair pen body 2, which is used to extend the overall length of the repair pen body 2.

[0024] It should be noted that the existing easy-to-use electrical and electronic repair pen technology has the following drawbacks: in relatively narrow spaces, the operator's hand is restricted by the space, making it difficult to insert the repair pen for inspection, thus making the use of the repair pen inconvenient; and the pen tip, i.e. the test head 3, is inconvenient to disassemble and assemble, thus making it impossible to replace different models of pen tips as needed.

[0025] In this embodiment, the inspection pen body 2 is held by hand so that the inspection head 3 can be brought into contact for inspection. The overall length of the inspection pen body 2 is adjusted by the extension mechanism 4, and the threaded rod 401 and the top plate 403 extend upward. The operator holds the threaded rod 401 so that the inspection head 3 can be inserted into the narrow space for inspection work, which facilitates the use of the inspection pen body 2. The disassembly and assembly mechanism 5 facilitates the disassembly and assembly of the inspection head 3, thereby allowing the inspection head 3 to be replaced.

[0026] In a further preferred embodiment of the present invention, the disassembly and assembly mechanism 5 includes: a damper 501 fixedly installed on the inner wall of one side of the mounting block 10, and a first return spring 502 installed on the outer wall of one end of the damper 501; a locking block 503 connected to one end of the damper 501, and a locking hole 507 that cooperates with the locking block 503 is provided on the inner wall of one side of the mounting groove 11.

[0027] In this embodiment, by installing the mounting block 10 of the detection head 3 into the mounting groove 11, the locking block 503 is squeezed inward as it enters, and the damper 501 and the first return spring 502 are squeezed and deformed. When it enters and passes through the lock hole 507, the damper 501 and the first return spring 502 reset, causing the locking block 503 to move outward and lock into the lock hole 507.

[0028] In a further preferred embodiment of the present invention, a pressure rod 506 is movably installed inside the lock hole 507, a second return spring 504 is installed on the outer side of one end of the pressure rod 506, and a pressure plate 505 is connected to one end of the pressure rod 506.

[0029] In this embodiment, by pressing the pressure plate 505 inward, the pressure plate 505 drives the pressure rod 506 to simultaneously squeeze the locking block 503 inward, so that the locking block 503 is squeezed out into the lock hole 507. Then, the detection head 3 is pulled out, and the mounting block 10 is taken out from the mounting groove 11, so that the detection head 3 can be removed.

[0030] In a further preferred embodiment of the present invention, a positioning plate 8 is fixedly installed on the outer wall of one side of the mounting block 10, and a positioning groove 9 that cooperates with the positioning plate 8 is provided on the inner wall of the other side of the mounting groove 11.

[0031] In this embodiment, by inserting the positioning plate 8 at one end of the detection head 3 into the positioning groove 9 of the mounting groove 11, and simultaneously inserting the mounting block 10 into the mounting groove 11, the positioning of the mounting block 10 and the mounting groove 11 is achieved by inserting the positioning plate 8 into the positioning groove 9.

[0032] In a further preferred embodiment of the present invention, a first magnetic ring 6 is embedded in the top of the detection head 3, and a second magnetic ring 7 is embedded in the bottom of the inspection pen body 2. The magnetic poles of the second magnetic ring 7 and the first magnetic ring 6 are opposite to each other.

[0033] In this embodiment, the detection head 3 and the inspection pen body 2 are quickly positioned and fixed by magnetic attraction between the first magnetic ring 6 and the second magnetic ring 7.

[0034] Example 2

[0035] Based on Embodiment 1, a preferred embodiment of the easy-to-use electrical and electronic inspection pen provided by this utility model is as follows: Figure 2 , Figure 4 and Figure 5 As shown: The extension mechanism 4 includes: a threaded rod 401 installed inside the inspection pen body 2, with a top plate 403 connected to the top of the threaded rod 401; and a rotating ring 402 threadedly installed on the outer side above the threaded rod 401.

[0036] In this embodiment, by rotating the rotating ring 402, the threaded rod 401 is moved upward through the threaded engagement between the rotating ring 402 and the threaded rod 401. After the threaded rod 401 moves out of the inspection pen body 2, the length of the inspection pen body 2 is extended.

[0037] In a further preferred embodiment of this utility model, a limiting groove 405 is provided at the top of the inspection pen body 2, and limiting blocks 404 that cooperate with the limiting groove 405 are connected to both sides below the rotating ring 402.

[0038] In this embodiment, while rotating the rotating ring 402, the limiting block 404 moves within the limiting groove 405 to limit the rotation ring 402.

[0039] In summary, the extension mechanism 4 extends the overall length of the inspection pen body 2, which facilitates inspection work in narrow spaces and makes it easy to use. The disassembly and assembly mechanism 5 facilitates the disassembly and assembly of the inspection head 3, thereby facilitating the replacement of the inspection head 3 and allowing for the replacement of inspection heads 3 with different signals as needed.
