Description

Technical Field

[0001] This utility model relates to the field of picking tools, and in particular to a picking tool for iron parts. Background Technology

[0002] Waste materials left over from the manufacturing and processing of steel bars, as well as small iron parts and objects such as bolts and nuts scattered on the ground, are difficult to clean up completely. Manually picking them up is time-consuming, laborious, inefficient, and requires constant bending over, which can cause physical harm. Utility Model Content

[0003] The purpose of this invention is to provide a tool for picking up iron parts. By holding the tool, iron parts can be attracted and picked up without bending over. When magnetic attraction is performed, the tool can extend to cover a wider picking range.

[0004] To achieve the above objectives, this utility model provides a tool for picking up ferrous parts, including a mounting base, a lifting rod, a movable base, a drive rod, and an electromagnet. The electromagnet is disposed at the bottom of the mounting base, and a battery supplying power to the electromagnet is provided inside the mounting base. A normally closed switch is provided between the battery and the electromagnet, and the normally closed switch is disposed on the top surface of the mounting base. The lifting rod is connected to the top surface of the mounting base, and a limiting baffle is provided at the upper part of the lifting rod. The movable base has a mating hole that slides with the lifting rod, and the drive rod is connected to the movable base. When the movable base presses against the mounting base, the normally closed switch is opened and the electromagnet is de-energized.

[0005] As a preferred embodiment of this utility model, the top surface of the movable seat is provided with a first magnet, and the bottom surface of the limiting baffle is provided with a second magnet that is magnetically attracted to the first magnet.

[0006] As a preferred embodiment of this utility model, the normally closed switch is a micro switch.

[0007] As a preferred embodiment of this utility model, the mounting base is provided with a guide rod, and the movable base is provided with a guide hole that slides with the guide rod.

[0008] As a preferred embodiment of this utility model, the guide rods are provided in two and symmetrically arranged on both sides of the lifting rod.

[0009] As a preferred embodiment of this utility model, the drive rod is provided in two parts and symmetrically arranged on both sides of the lifting rod.

[0010] As a preferred embodiment of this utility model, the tops of the two drive rods are connected by a drive handle.

[0011] As a preferred embodiment of this utility model, the top of the lifting rod is provided with a lifting handle.

[0012] Compared with the prior art, the advantages of this utility model embodiment of the iron parts picking tool are as follows:

[0013] In this invention, when magnetically attracting ferrous parts, the drive rod moves upward relative to the lifting rod, causing the movable seat to abut against the limit baffle. This creates a closed circuit between the electromagnet, the normally closed switch, and the battery. When the electromagnet is energized, it possesses magnetic force, allowing the hand-held drive rod to attract ferrous parts without bending over. When it is necessary to remove the ferrous parts collected by the electromagnet, the drive rod moves downward relative to the lifting rod, causing the movable seat to press against the top surface of the mounting base and simultaneously against the normally closed switch, thus activating the normally closed switch. When the switch is off, the electromagnet loses its power and magnetic force, causing ferrous parts to fall from the electromagnet into the collection container. Furthermore, the lifting rod and drive rod work together to extend and retract the ferrous parts pickup tool. During magnetic attraction, the tool extends, covering a wider pickup area. When the tool is stored, the movable seat presses against the mounting base, and the tool shortens, reducing its space occupation. At this time, the electromagnet is de-energized, preventing it from being powered during non-operational periods and extending battery life. Attached Figure Description

Detailed Implementation

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] like Figures 1 to 3 As shown, a preferred embodiment of the present invention provides a tool for picking up iron parts, comprising a mounting base 1, a lifting rod 2, a movable base 3, a drive rod 4, and an electromagnet 5. The electromagnet 5 is disposed at the bottom of the mounting base 1, and a battery is provided inside the mounting base 1 to supply power to the electromagnet 5. A normally closed switch 6 is provided between the battery and the electromagnet 5, and the normally closed switch 6 is disposed on the top surface of the mounting base 1. The electromagnet 5, the normally closed switch 6, and the battery are connected in series to form a closed circuit structure. The lifting rod 2 is connected to the top surface of the mounting base 1, and a limiting baffle 21 is provided on the upper part of the lifting rod 2. The movable base 3 is provided with a mating hole that slides with the lifting rod 2. The drive rod 4 is connected to the movable base 3. When the movable base 3 presses against the mounting base 1, the normally closed switch 6 is opened and the electromagnet 5 is de-energized.

[0022] When magnetically attracting ferrous parts, the drive rod 4 moves upward relative to the lifting rod 2, causing the movable seat 3 to abut against the limit baffle 21. This creates a closed circuit between the electromagnet 5, the normally closed switch 6, and the battery. The electromagnet 5, when energized, possesses magnetic force, allowing the hand-held drive rod 4 to attract ferrous parts without bending over. When the ferrous parts collected by the electromagnet 5 need to be removed, the drive rod 4 moves downward relative to the lifting rod 2, causing the movable seat 3 to press against the top surface of the mounting base 1 and simultaneously against the normally closed switch 6, thus preventing the normally closed switch from moving upward. When the closed switch 6 is open, the electromagnet 5 is de-energized and loses its magnetic force, causing the ferrous parts to fall from the electromagnet 5 into the collection container. Furthermore, the lifting rod 2, in conjunction with the drive rod 4, enables the extension and retraction of the ferrous parts picking tool. During magnetic attraction, the tool extends, covering a wider picking area. When the tool is stored, the movable seat 3 presses against the mounting base 1, and the tool shortens, reducing its space occupation. At this time, the electromagnet 5 is de-energized, preventing it from being powered during non-operational periods and extending battery life.

[0023] For example, the top surface of the movable seat 3 is provided with a first magnet 31, and the bottom surface of the limiting baffle 21 is provided with a second magnet 22 that is magnetically attracted to the first magnet 31. In use, the movable seat 3 can be positioned on the limiting baffle 21 by the attraction of the first magnet 31 and the second magnet 22, thus preventing the movable seat 3 from shaking up and down at will; moreover, the relative movement of the hand-held drive rod 4 and the lifting rod 2 can realize the separation between the movable seat 3 and the limiting baffle 21.

[0024] For example, the normally closed switch 6 is a micro switch with high sensitivity, ensuring that the normally closed switch 6 responds quickly when the movable seat 3 is pressed against the mounting seat 1.

[0025] For example, the mounting base 1 is provided with a guide rod 7, and the movable base 3 is provided with a guide hole that slides with the guide rod 7 to ensure that the movable base 3 moves stably on the lifting rod 2 and avoids deviation. Furthermore, two guide rods 7 are provided and symmetrically arranged on both sides of the lifting rod 2 to improve the stability of the movable base 3 as it moves up and down on the lifting rod 2.

[0026] Furthermore, the drive rod 4 is provided in two symmetrical positions on both sides of the lifting rod 2 to improve the moving stability of the movable seat 3.

[0027] For example, the tops of the two drive rods 4 are connected by a drive handle 41; the top of the lifting rod 2 is provided with a lifting handle 23, which makes it convenient for the user to drive the drive rod 4 and the lifting rod 2 to move relative to each other.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
