Description

Technical Field

[0001] The utility model belongs to the technical field of electro-test pens, and particularly relates to an anti-detachment portable electro-test pen. Background Art

[0002] An electro-test pen, also called a voltage detector, is simply referred to as an "electric pen". It is an electrician's tool used to test whether an electric wire is charged. There is a neon bulb in the body. When testing, if the neon bulb lights up, it means that the wire is charged or is a live wire in a conducting path.

[0003] For example, a Chinese patent with the publication number CN211905506U discloses a portable electro-test pen, which includes an electro-test pen housing. A metal pen rod is fixedly connected and installed at the end of the electro-test pen housing. A fixing spiral ring is spirally installed on the surface of the metal pen rod. A screwdriver head is fixedly connected and installed at the other end of the metal pen rod. A resistance component is fixedly installed inside the electro-test pen housing. A neon tube is electrically connected and installed at one end of the resistance component inside the electro-test pen housing. The portable electro-test pen of the utility model can rotate and disassemble or install screws, thereby increasing its practical performance. Moreover, the disassembly and installation are relatively convenient. And the hexagonal column of the metal pen rod can be disassembled from the hexagonal port after loosening, and then the metal pen rod can be placed in the storage groove and clamped by the fixing card, so as to reduce the length of the whole electro-test pen and make the electro-test pen more convenient to carry and use later.

[0004] When the existing portable electro-test pen is in use, the tip of the electro-test pen falls off and is collided, resulting in damage to the tip. In view of this, we propose an anti-detachment portable electro-test pen. Content of the Utility Model

[0005] The purpose of the utility model is to provide an anti-detachment portable electro-test pen to solve the problem that the tip of the electro-test pen falls off and is collided, resulting in damage to the tip as proposed in the above background art.

[0006] In view of this, the utility model provides an anti-detachment portable electro-test pen, which includes an electro-test pen body. A connection contact is fixedly connected to the outer wall of the electro-test pen body. A monitoring tip is fixedly connected to one end of the electro-test pen body. A pen sleeve is sleeved outside the monitoring tip. A dial is slidably connected to the outer wall of the electro-test pen body on one side of the connection contact. A connection slide plate is fixedly connected to the outer wall of the dial. Connection chutes are opened at both ends of the connection slide plate. Connection columns are movably connected to the outer walls of the connection chutes. A connection plate is fixedly connected to the top ends of the connection columns. A limiting rod fixedly connected to the inner wall of the electro-test pen body penetrates through the inner wall of the connection plate. A spring is fixedly connected to the outer wall of the connection plate. A clamping block is fixedly connected to one end of the connection plate. A clamping groove is opened at the connection part of the pen sleeve and the clamping block;

[0007] Connecting component, which is located at the bottom end of the electrical pen body and is used for connecting the pen cap.

[0008] In this technical solution, the staff puts the pen cap on the outside of the monitoring pen tip. At the same time, the connecting block at the bottom end of the monitoring pen tip drives the telescopic slide plate to slide along the inner wall of the limiting groove through the rib, resetting the telescopic slide plate. Then, the spring drives the connecting plate to slide along the outer wall of the limiting rod through its own elastic force. The sliding of the connecting plate drives the clamping block to engage with the clamping groove, realizing the protection operation of the monitoring pen tip and avoiding damage to the monitoring pen tip caused by collision after it falls off.

[0009] In the above technical solution, further, the connecting chute is inclined in shape, and the connecting plate and the limiting rod form a sliding structure through the connecting chute and the connecting column.

[0010] In this technical solution, the sliding of the connecting chute drives the connecting plate to slide along the outer wall of the limiting rod against the elastic force of the spring through the connecting column, realizing the sliding operation of the connecting plate.

[0011] In the above technical solution, further, the clamping block is in an "L" shape, and the clamping groove is in a "T" shape.

[0012] In this technical solution, it is beneficial for the connecting plate to slide and drive the clamping block to engage with the clamping groove.

[0013] In the above technical solution, further, the electrical pen body and the pen cap form a fixed connection structure through the clamping block and the clamping groove.

[0014] In this technical solution, the spring drives the connecting plate to slide along the outer wall of the limiting rod through its own elastic force. The sliding of the connecting plate drives the clamping block to engage with the clamping groove, realizing the protection operation of the monitoring pen tip and avoiding damage to the monitoring pen tip caused by collision after it falls off.

[0015] In the above technical solution, further, the outer wall of the pen cap is provided with an anti-slip gasket.

[0016] In this technical solution, it is convenient for the staff to quickly pull out the pen cap.

[0017] In the above technical solution, further, the connecting component includes:

[0018] Connecting frame, the bottom end of the electrical pen body is fixedly connected with the inner wall of the connecting frame. A telescopic slide plate is slidably connected to the connecting frame. A limiting groove is opened at the connecting part of the connecting frame and the telescopic slide plate. The top end of the telescopic slide plate is fixedly connected with a connecting belt. Ribs are fixedly connected to the outer wall of the connecting belt. One end of the connecting belt is fixedly connected with a connecting block fixedly connected to the bottom end of the pen cap.

[0019] In this technical solution, the staff puts the pen cap on the outside of the monitoring pen tip. At the same time, the movement of the connecting block at the bottom end of the monitoring pen tip drives the telescopic slide plate to slide along the inner wall of the limiting groove through the rib, resetting the telescopic slide plate. By setting the connecting belt, the pen cap is prevented from falling off.

[0020] In the above technical solution, further, there are three groups of the ribs, and the three groups of the ribs are equidistantly distributed along the outer wall of the connecting belt.

[0021] In this technical solution, it is beneficial for the movement of the connecting block at the bottom end of the monitoring pen tip to drive the telescopic slide plate to slide along the inner wall of the limiting groove through the rib.

[0022] The beneficial effects of the present utility model are:

[0023] 1. For this anti-dropping portable electroscope pen, by setting the clamping block and the clamping groove, the staff puts the pen cap on the outside of the monitoring pen tip. At the same time, the movement of the connecting block at the bottom end of the monitoring pen tip drives the telescopic slide plate to slide along the inner wall of the limiting groove through the rib, resetting the telescopic slide plate. Then, the spring drives the connecting plate to slide along the outer wall of the limiting rod through its own elastic force, and the sliding of the connecting plate drives the clamping block to engage with the clamping groove, realizing the protection operation of the monitoring pen tip and preventing the monitoring pen tip from being damaged due to collision after falling off.

[0024] 2. For this anti-dropping portable electroscope pen, by setting the connecting chute, the sliding of the connecting chute drives the connecting plate to slide along the outer wall of the limiting rod against the elastic force of the spring through the connecting column, so that the sliding of the connecting plate drives the clamping block to move away from the clamping groove. Then, the staff pulls the pen cap so that the pen cap moves away from the monitoring pen tip. At the same time, the movement of the pen cap drives the telescopic slide plate to slide along the inner wall of the limiting groove through the connecting belt. By setting the connecting belt, the pen cap is prevented from falling off. BRIEF DESCRIPTION OF THE DRAWINGS
