Description

Technical Field

[0001] This utility model relates to the field of electrical circuit testing technology, and in particular to a multifunctional electrical circuit testing pen. Background Technology

[0002] A testing pen is a tool with specific detection functions. It looks like an ordinary pen, but it has various built-in sensors and detection modules. Testing pens can be used to detect a variety of substances or environmental indicators. With its convenient and fast detection features, testing pens play an important role in many fields and provide strong support for people's lives, production and scientific research.

[0003] An electrical circuit testing pen is a tool specifically designed to detect relevant parameters and conditions of electrical circuits. Common types include voltage test pens, also called voltage pens, and digital testing pens with more functions. These pens display test data intuitively on a digital screen, allowing electrical maintenance personnel and technicians to quickly and accurately determine whether there are faults in the electrical circuits and the type of fault, ensuring the safe operation of electrical equipment and lines. In the past, electrical circuit testing was performed using two different devices. Now, multiple sensors are integrated into a single device, achieving the effect of multiple tests with a single device. However, the probes of existing multi-functional electrical circuit testing pens are directly welded to the device. This method of fixing means that if the probes are damaged, they cannot be replaced individually; the entire multi-functional electrical circuit testing pen must be replaced, thus increasing replacement costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-functional electrical circuit testing pen, which aims to improve the problem that in the existing technology, the testing pen cannot be replaced individually after the probe is damaged, and only the entire multi-functional electrical circuit testing pen can be replaced, thus increasing the replacement cost.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multifunctional electrical circuit testing pen, comprising a body, a fixing tube fixedly connected to the upper right side of the body, multiple buckles slidably connected at equal intervals on the inner side of the fixing tube, a turntable rotatably connected to the inner right side of the fixing tube, multiple guide grooves equidistantly formed on the outer wall of the turntable, multiple connecting rods fixedly connected at equal intervals on the right side of the turntable, a rotating ring fixedly connected to the right end of each of the multiple connecting rods, a detection rod slidably connected to the inner side of the fixing tube, and an extension mechanism fixedly connected to the right side of the detection rod, the extension mechanism being used to extend the detection length.

[0006] As a further description of the above technical solution:

[0007] The extension mechanism includes an outer rod, the left end of which is fixedly connected to the right end of the probe rod. An extension rod is slidably connected to the inner side of the outer rod. A fixing buckle is fixedly connected to the left end of the outer wall of the extension rod. A sliding groove is provided on the lower side of the inner wall of the outer rod, and the sliding groove is slidably connected to the fixing buckle. Multiple fixing grooves are provided at equal intervals on the inner wall of the outer rod. A pop-out head is fixedly connected to the right end of the extension rod.

[0008] As a further description of the above technical solution:

[0009] A rubber ring is fixedly connected to the outer wall of the rotating ring, and the outer wall of the rubber ring is provided with anti-slip texture.

[0010] As a further description of the above technical solution:

[0011] An insulating sleeve is fixedly connected to the outer wall of the outer rod, and a fixing ring is fixedly connected to the left and right ends of the outer wall of the insulating sleeve.

[0012] As a further description of the above technical solution:

[0013] A display screen is fixedly connected to the top of the machine body, and a light is fixedly connected to the lower right side of the machine body.

[0014] As a further description of the above technical solution:

[0015] A rubber sleeve is fixedly connected to the lower side of the machine body, and a gripping groove is provided on the outer wall of the rubber sleeve.

[0016] As a further description of the above technical solution:

[0017] A fixing plate is fixedly connected to the top left side of the machine body, and a clamping plate is fixedly connected to the upper right end of the fixing plate.

[0018] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the rotating ring drives the turntable to rotate via the connecting rod. When the turntable rotates, it drives the corresponding buckle to slide outward via the guide groove, thereby replacing the probe rod. Then, the rotating ring is rotated in the opposite direction, and the buckle slides inward via the connecting rod, turntable and guide groove, thereby fixing the probe rod. This achieves the effect of replacing the probe rod individually, thereby reducing the replacement cost.

[0022] 2. In this utility model, pinching the pop-out head drives the extension rod to rotate, thereby causing the fixing buckle to slide out of the fixing groove and into the slide groove. Then, the extension rod is pulled to extend it to the right. When the extension rod extends to the appropriate length, the extension rod is rotated in the opposite direction to drive the fixing buckle to slide into the fixing groove at the corresponding position for fixing. This achieves the effect of adjusting the detection length. Attached Figure Description

[0031] 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.

[0032] Reference Figure 3 and Figure 4An embodiment of this utility model provides a multifunctional electrical circuit testing pen, including a body 1. A fixed tube 3 is fixedly connected to the upper right side of the body 1. Multiple buckles 4 are equidistantly slidably connected to the inner side of the fixed tube 3. The buckles 4 slide within the fixed tube 3. A turntable 5 is rotatably connected to the inner right side of the fixed tube 3. Multiple guide grooves 6 are equidistantly provided on the outer wall of the turntable 5. The turntable 5 drives the buckles 4 to move through the guide grooves 6. Multiple connecting rods 7 are fixedly connected to the right side of the turntable 5. A rotating ring 8 is fixedly connected to the right end of each of the multiple connecting rods 7. The rotating ring 8 drives the turntable 5 to rotate through the connecting rods 7. A detection rod 9 is slidably connected to the inner side of the fixed tube 3. An extension mechanism 2 is fixedly connected to the right side of the detection rod 9. The extension mechanism 2 is used to extend the detection length. A rubber ring 10 is fixedly connected to the outer wall of the rotating ring 8. Anti-slip textures 11 are provided on the outer wall of the rubber ring 10. The anti-slip textures 11 are used to increase the friction of the rubber ring 10.

[0033] Specifically, rotating the rotating ring 8 causes multiple connecting rods 7 fixed on the left side to move and rotate along a trajectory. This causes the turntable 5 to rotate within the fixed tube 3 via the connecting rods 7. When the turntable 5 rotates within the fixed tube 3, it causes the corresponding buckles 4 to slide outward within the fixed tube 3 via the multiple guide grooves 6. Then, the probe rod 9 is replaced. Then, rotating the rotating ring 8 in the opposite direction causes the turntable 5 to rotate via the connecting rods 7. This causes the corresponding buckles 4 to slide inward via the multiple guide grooves 6, thereby fixing the probe rod 9. The rubber ring 10 fixed outside the rotating ring 8 has anti-slip textures 11 on its outside to increase its friction.

[0034] Reference Figure 1 , Figure 5 and Figure 6 The extension mechanism 2 includes an outer rod 201, the left end of which is fixedly connected to the right end of the probe rod 9. An extension rod 202 is slidably connected to the inner side of the outer rod 201. A fixing buckle 203 is fixedly connected to the left end of the outer wall of the extension rod 202. A sliding groove 204 is provided on the lower side of the inner wall of the outer rod 201. The sliding groove 204 is slidably connected to the fixing buckle 203. Multiple fixing grooves 205 are provided at equal intervals on the inner wall of the outer rod 201. A pop-out head 206 is fixedly connected to the right end of the extension rod 202. An insulating sleeve 12 is fixedly connected to the outer wall of the outer rod 201. Fixing rings 13 are fixedly connected to both the left and right ends of the outer wall of the insulating sleeve 12. The fixing rings 13 are used to fix the insulating sleeve 12. A display screen 14 is fixedly connected to the top of the body 1. A lighting lamp 15 is fixedly connected to the lower right side of the body 1. The lighting lamp 15 is used for auxiliary lighting.

[0035] Specifically, pinching the ejector head 206 and rotating it causes the extension rod 202 to rotate. The rotation of the extension rod 202 causes the fixing buckle 203 to slide out of the fixing groove 205 opened in the outer rod 201, so that the fixing buckle 203 slides into the slide groove 204. Then, pull the extension rod 202 to the right to extend it to the right. When the extension rod 202 extends to the appropriate length, rotate the extension rod 202 in the opposite direction, so that the fixing buckle 203 slides into the fixing groove 205 in the corresponding position for fixing. The insulating sleeve 12 fixed to the outer rod 201 by the fixing ring 13 can provide insulation for the extension mechanism 2. The display screen 14 fixed on the machine body 1 can display the test results in real time, and the lighting lamp 15 installed at the front of the machine body 1 can provide illumination during the test.

[0036] Reference Figure 1 and Figure 2 A rubber sleeve 16 is fixedly connected to the lower side of the body 1. A gripping groove 17 is provided on the outer wall of the rubber sleeve 16. The gripping groove 17 is used to improve the gripping performance of the rubber sleeve 16. A fixing plate 18 is fixedly connected to the top left side of the body 1. A clamping plate 19 is fixedly connected to the upper right end of the fixing plate 18. The fixing plate 18 is used to fix the clamping plate 19. A connecting rope 20 is fixedly connected to the left side of the body 1. A hanging ring 21 is fixedly connected to the left end of the connecting rope 20. The connecting rope 20 is used to connect the hanging ring 21.

[0037] Specifically, the rubber sleeve 16 fixed to the outside of the body 1 improves the grip of the multi-functional electrical circuit test pen through the grip groove 17 opened on it, the clamp 19 fixed by the fixing piece 18 makes it easy to clamp the multi-functional electrical circuit test pen to clothing, and the hanging ring 21 connected to the body 1 by the connecting rope 20 makes it easy to hang the multi-functional electrical circuit test pen.

[0038] Working principle: When the probe rod 9 of the multi-functional electrical circuit tester is damaged, firstly, the rotating ring 8 is rotated, which drives the multiple connecting rods 7 fixed on the left side to move and rotate along the trajectory. In this way, the multiple connecting rods 7 drive the turntable 5 to rotate inside the fixed tube 3. When the turntable 5 rotates inside the fixed tube 3, it will drive the corresponding buckles 4 to slide outward inside the fixed tube 3 through the multiple guide grooves 6 opened on it. Then the probe rod 9 can be replaced. Then, the rotating ring 8 is rotated in the opposite direction, which drives the turntable 5 to rotate through the connecting rods 7. In this way, the multiple guide grooves 6 drive the corresponding buckles 4 to slide inward, thereby fixing the probe rod 9. This achieves the effect of replacing the probe rod 9 individually, thereby reducing the replacement cost.

[0039] When using a multi-functional electrical circuit testing pen to test electrical circuits, if the pen is not long enough, first pinch the pop-out head 206 and rotate it to rotate the extension rod 202. The rotation of the extension rod 202 causes the fixing buckle 203 to slide out of the fixing groove 205 in the outer rod 201, so that the fixing buckle 203 slides into the slide groove 204. Then pull the extension rod 202 to the right to extend it to the right. When the extension rod 202 extends to the appropriate length, rotate the extension rod 202 in the opposite direction to drive the fixing buckle 203 to slide into the corresponding fixing groove 205 for fixing. This achieves the effect of adjusting the detection length of the multi-functional electrical circuit testing pen.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
