Abstract
Description
Technical Field
[0001] The utility model relates to the field of low-voltage current signal grounding, in particular to a current signal grounding pin. Background Art
[0002] Current signal grounding pins are primarily used for fast and secure grounding of low-voltage current signals. To ensure reliable performance, the current signal grounding pins must be inserted a certain distance underground, and the connection between the grounding wire and the pin must be convenient and secure. However, existing grounding pins are often soft or lack a specifically designed connection between the grounding wire and the pin. This often results in poor penetration or a loose connection during operation, thus impacting detection efficiency.
[0003] Patent publication number "CN109301525A" discloses a "portable retractable grounding pin." However, the patent's technical solution employs three grounding pins: a main grounding pin, a left grounding pin, and a right grounding pin. Its main improvement is to ensure uniform force distribution when the grounding pin is driven into the ground, thereby increasing its service life. However, it lacks a designated hammering position, a grounding wire connection location, or safety precautions, resulting in inconvenient operation and low safety.
[0004] To this end, our company proposes a current signal grounding pin. Summary of the Invention
[0005] The purpose of the utility model is to provide a current signal grounding pin, which can be conveniently inserted into the ground and can be reliably connected to the grounding wire.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A current signal grounding needle comprises a needle body, wherein the needle body is provided with a first pressing portion, a wire clamping portion and a second pressing portion from top to bottom.
[0008] Preferably, a pointed cone portion is provided at the bottom of the needle body.
[0009] Preferably, an outer edge of the second pressing portion projected in the vertical direction is located outside the outer edge of the first pressing portion projected in the vertical direction.
[0010] Preferably, the wire clamping portion is in a circular ring shape.
[0011] Preferably, the line clamping portion is provided on the lower end surface of the first pressing portion.
[0012] Preferably, the second pressing portion is located on one side of the needle body, and the upper end surface of the second pressing portion has a concave plane.
[0013] Preferably, the upper end surface of the first pressing portion is a plane.
[0014] The beneficial effects of the utility model are:
[0015] 1. When the soil is soft, you can bury the grounding needle by stepping on the second pressing part; when the soil is hard, you can bury the grounding needle by hammering the first pressing part. At this time, you can hold the second pressing part with your hand to prevent the grounding needle from tilting; after the grounding needle is buried, you can connect the grounding wire to the clamping part to achieve a reliable grounding connection.
[0016] 2. The outer edge of the second pressing part is located on the outside of the first pressing part to prevent hands from being hit when holding the hand.
[0017] 3. The circular wire clamping part is not only convenient for connecting with the grounding fish clamp line, but also convenient for hand-carrying or pulling out from the ground after use. BRIEF DESCRIPTION OF THE DRAWINGS
[0018] Figure 1 This is the main view of the utility model;
[0019] Figure 2 It is a right view of the utility model.
[0020] The accompanying drawings are for illustrative purposes only and are not to be construed as limitations on this patent. To better illustrate this embodiment, some components of the accompanying drawings may be omitted, enlarged, or reduced in size, and do not represent the actual dimensions of the product. For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted from the accompanying drawings. DETAILED DESCRIPTION
[0021] The present invention will be further described below in conjunction with the accompanying drawings.
[0022] Example 1
[0023] like Figure 1 and Figure 2 As shown, a current signal grounding needle of the present embodiment comprises a needle body 1, on which a first pressing portion 2, a wire clamping portion 3 and a second pressing portion 5 are respectively provided from top to bottom. The wire clamping portion 3 is annular and is arranged on the lower end face of the first pressing portion 2, which is not only convenient for connection with the grounding fish clamping line, but also convenient for hand-carrying or pulling out from the ground after use. The outer edge of the second pressing portion 5 projected in the vertical direction is located outside the first pressing portion 2 projected in the vertical direction. When beating the first pressing portion 2, the second pressing portion 5 can be supported by hand to prevent it from tilting, and at the same time, the hands can be effectively protected to avoid being injured. There is a concave plane on the upper end face of the second pressing portion 5, which is convenient for stepping on. When the soil is relatively soft, it can be buried underground by stepping on it.
[0024] A pointed cone portion 4 is provided at the bottom of the needle body 1. The pointed cone may be in the shape of a hexagonal pyramid, which can be conveniently pressed into the ground.
[0025] The second pressing portion 5 is located on one side of the needle body 1 and can be conveniently welded to the needle body 1 as a whole.
[0026] The upper end surface of the first pressing portion 2 is flat, which is convenient for hammering downwards.
[0027] When the needle body of the present invention is in use, if it cannot be buried underground by stepping on it, depending on the soil conditions, it can be buried underground by hammering the first pressing part 2; then the clamping part 3 is connected to the grounding fish clamp to achieve safe grounding.
