Description

Technical Field

[0001] This utility model belongs to the field of power testing instrument technology, and specifically relates to a power testing instrument. Background Technology

[0002] Electrical testing instruments are devices used to measure, monitor, analyze, and diagnose various parameters and performance of power systems. Common electrical testing instruments include multimeters and oscilloscopes. Multimeters can measure basic electrical parameters such as voltage, current, and resistance.

[0003] When using a multimeter, the probes need to contact the circuit. However, the probe tips of a multimeter are quite sharp, and current technology lacks a mechanism to protect them. After use, the probe tips are exposed and easily damaged by collisions with other objects, and they can also easily injure the operator. Therefore, a technical measure is proposed to solve the problem of the lack of a mechanism to protect the probe tips in current technology, which makes the probe tips exposed after use susceptible to damage from collisions with other objects and easy to injure the operator. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an electrical testing instrument, which aims to solve the problem that there is no mechanism to protect the pen tip. After the multimeter is used, the pen tip is exposed and is easily damaged by collision with other objects, and it is also easy to injure the operator.

[0006] (2) Technical solution

[0007] To address the aforementioned technical problems, this utility model provides a power testing instrument comprising a main body with multiple evenly distributed interfaces. Each interface is movably connected to a test lead. An insulating post is mounted at the other end of each test lead, and a pen tip is connected to the lower part of the insulating post. An insertion hole is formed on the outer side of the insulating post. A limiting component is installed within the main body. Two sets of circular holes are formed on the side of the main body, and the positions of these holes are adapted to the limiting component. The insulating post slides within the circular holes. Thanks to the limiting component, insertion hole, and circular holes, the pen tip is protected, preventing it from being exposed after use. This avoids collisions between the multimeter pen tip and other objects, preventing damage to the multimeter pen tip, extending the multimeter's lifespan, and preventing the multimeter pen tip from injuring the operator, thus improving the safety of multimeter use.

[0008] Furthermore, a display screen is provided at the end of the body away from the circular hole.

[0009] Furthermore, the probe is equipped with a knob, which is located between the display screen and the interface.

[0010] Furthermore, a charging port is provided on the side of the main body.

[0011] Furthermore, a limiting plate is fitted around the middle of the outer side of the insulating post, and the insertion hole is below the limiting plate. A marking line is provided on the upper surface of the limiting plate, and the marking line is on the same side as the insertion hole.

[0012] Furthermore, the limiting component includes a button that is slidably adapted to the body, a lifting plate is connected to the lower part of the button, and the button is located in the middle of the lifting plate. A frame is installed on the lower part of the lifting plate.

[0013] Furthermore, two sets of symmetrically distributed insert rods are installed inside the frame, and two sets of symmetrically distributed slide plates are installed at the middle position of the side of the frame. The slide plates are slidably connected to limit rods, and the limit rods are fixedly installed inside the main body. Two sets of symmetrically distributed springs are installed on the lower surface of the frame, and the lower ends of the springs are installed inside the main body.

[0014] Furthermore, the insertion rod and the insertion hole are slidably adapted.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention, through the design of a limiting component, a socket, and a round hole, achieves the function of protecting the pen tip, thereby preventing the pen tip from being exposed after the multimeter has been used. This avoids collisions between the multimeter pen tip and other objects, prevents damage to the multimeter pen tip, extends the service life of the multimeter, and also prevents the multimeter pen tip from injuring the operator, thus improving the safety of multimeter use. Pressing down the button moves the frame downward, compressing the spring. The downward movement of the frame moves the plug rod downward, releasing the limiting of the socket. Then, the probe is removed. When the probe needs to be protected, the above actions are repeated. Then, the probe is inserted, and then the button is released. Under the rebound of the spring, the plug rod is re-inserted into the socket. Attached Figure Description

[0024] 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.

[0025] This specific embodiment is a power testing instrument, the structural schematic diagram of which is shown below. Figure 1 , Figure 2 , Figure 3As shown, the multimeter includes a main body 1, which has multiple evenly distributed interfaces 5. Each interface 5 is movably connected to a probe 7. An insulating post 9 is installed at the other end of each probe 7, and a pen tip 11 is connected to the lower part of the insulating post 9. A socket 10 is opened on the outer side of the insulating post 9. A limiting component 2 is installed inside the main body 1. Two sets of circular holes 8 are opened on the side of the main body 1, and the circular holes 8 are matched with the position of the limiting component 2. The insulating post 9 is slidably matched with the circular holes 8. A display screen 3 is located at the end of the main body 1 away from the circular holes 8. A knob 6 is located on the probe 7, between the display screen 3 and the interfaces 5. A charging port 4 is located on the side of the main body 1. A limiting plate 12 is fitted around the middle of the outer side of the insulating post 9, and the socket 10 is below the limiting plate 12. A marking line 13 is provided on the upper surface of the limiting plate 12, and the marking line 13 is on the same side as the socket 10. In actual use of the multimeter, the probe 7 is connected to different interfaces 5 according to the actual situation on site. Typically, there are multiple interfaces 5, including a common interface 5, voltage, resistance and diode measurement interfaces 5, and high current measurement interface 5. Then, rotate the knob 6 to switch between different parameter measurements (the knob 6 can be switched to measure various electrical parameters such as DC voltage, AC voltage, DC current, AC current, resistance, capacitance, and inductance). Then, release the limit on the insulating post 9 through the limit component 2, place the main body 1 on the ground, and then pick up the test probe 7 so that the probe tip 11 contacts the wire to start the power test. After the test is completed, insert the insulating post 9 into the round hole 8 (where the marking line is vertically downward, and the insertion hole 10 is vertically downward at this time. The insulating post 9 is made of rubber, and there is a certain friction between the insulating post 9 and the round hole 8. After the insulating post 9 enters the round hole 8, it is not easy for it to rotate). The limit component 2 then limits the insulating post 9 again, thus completing the protection of the probe tip 11.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the limiting component 2 includes a button 201, which is slidably adapted to the body 1. A lifting plate 202 is connected to the lower part of the button 201, and the button 201 is positioned in the middle of the lifting plate 202. A frame 206 is installed at the lower part of the lifting plate 202. Two sets of symmetrically distributed insert rods 205 are installed inside the frame 206. Two sets of symmetrically distributed slide plates 203 are installed at the middle of the side of the frame 206. The slide plates 203 are slidably connected to a limiting rod 204, which is fixedly installed inside the body 1. Two sets of symmetrically distributed springs 207 are installed on the lower surface of the frame 206, with the lower ends of the springs 207 installed inside the body 1. The insert rods 205 are slidably adapted to the insertion holes 10. Pressing the button 201 downwards... The button 201 moves downward, causing the lifting plate 202 to move downward. The lifting plate 202 moves downward, causing the frame 206 to move downward. The frame 206 moves downward, causing the slide plate 203 to slide downward along the limit rod 204. The frame 206 moves downward, compressing the spring 207. The frame 206 moves downward, causing the insertion rod 205 to move downward. The insertion rod 205 moves downward, releasing the limit on the socket 10. Then, the test probe 7 is taken out. When it is necessary to protect the test probe 7, the above actions are repeated. Then, the test probe 7 is inserted (with the marking line facing vertically downward, and the socket 10 facing vertically downward). Then, the button 201 is released, and the spring 207 rebounds, causing the insertion rod 205 to be reinserted into the socket 10.

[0027] Working principle: When using a multimeter, connect the probes 7 to different interfaces 5 according to the actual situation on site (multimeters usually have multiple interfaces 5, including common interface 5, voltage, resistance and diode measurement interfaces 5, and high current measurement interface 5). Then rotate the knob 6 to switch between different parameter measurements (knob 6 can be switched to measure various electrical parameters such as DC voltage, AC voltage, DC current, AC current, resistance, capacitance, and inductance). Then, release the limit on the insulating post 9 through the limit component 2, place the body 1 on the ground, and then pick up the probes 7 so that the tip 11 contacts the wire to start the power detection. After the detection is completed, insert the insulating post 9 into the round hole 8 (where the marking line is vertically downward, the insertion hole 10 is vertically downward at this time, the insulating post 9 is made of rubber, and there is a certain friction between the insulating post 9 and the round hole 8. After the insulating post 9 enters the round hole 8, it is not easy for it to rotate). The limit component 2 re-limits the insulating post 9, thereby completing the protection of the tip 11.

[0028] The specific working method of the limiting component 2 is as follows: Pressing down on button 201 causes button 201 to move downward, which in turn moves lifting plate 202 downward. The downward movement of lifting plate 202 causes frame 206 to move downward. The downward movement of frame 206 causes slide plate 203 to slide downward along limiting rod 204. The downward movement of frame 206 compresses spring 207. The downward movement of frame 206 causes insertion rod 205 to move downward. The downward movement of insertion rod 205 releases the limitation on insertion hole 10. Then, the test probe 7 is removed. When protection of test probe 7 is required, the above actions are repeated, and then test probe 7 is inserted. (The marking line is vertically downwards, and the socket 10 is vertically downwards at this time.) Then, release the button 201. Under the rebound action of the spring 207, the plug rod 205 is driven to re-insert into the socket 10. Through the setting of the limiting component 2, the socket 10, and the round hole 8, the pen tip 11 is protected, thereby preventing the pen tip 11 from being exposed after the multimeter is used. This avoids the multimeter pen tip 7 from colliding with other objects, prevents the multimeter pen tip 7 from being damaged, and extends the service life of the multimeter. At the same time, it also prevents the multimeter pen tip 7 from piercing the operator, thus improving the safety of using the multimeter.
