Description

Technical Field

[0001] This utility model relates to the field of pickups, and more particularly to a small magnetic pickup. Background Technology

[0002] Magnetic pickers, as a common metal recycling tool, are widely used in machining, construction and other fields. They are mainly used to pick up scattered ferromagnetic parts or tools. Traditional telescopic magnetic pickers mostly adopt an elastic telescopic metal tube structure, which achieves the telescopic function through the elastic deformation of the metal tube. The magnetic head is fixed to the end of the tube. However, when this type of existing technology is used, the elastic metal tube still maintains a large rebound force after contraction, and it is easy to extend on its own due to slight external force, resulting in the problem of taking up too much space during transportation or storage.

[0003] Therefore, a small magnetic pickup device was designed. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a small magnetic pickup, which solves the problem that traditional telescopic magnetic pickups, which use an elastic metal tube structure, still have a large rebound force after shrinking and are prone to stretching due to external forces, making them inconvenient to store.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A small magnetic pickup includes a magnetic head, a metal bellows, a rubber handle, two round rods fixedly mounted on the magnetic head, a movable sleeve fitted on the rubber handle for engaging with the round rods, and a fixing strap located at one end of the rubber handle for winding, storing, and fixing the metal bellows.

[0006] Preferably, the two circular rods are circumferentially distributed at the end of the magnetic head away from the metal bellows.

[0007] Preferably, a limit ring and a mounting ring are fixedly provided at both ends of the metal bellows to limit the movement trajectory of the movable sleeve.

[0008] Preferably, the movable sleeve is annular and has a slot on its outer wall, and a limiting plate is fixedly provided at the end of the movable sleeve away from the slot.

[0009] Preferably, the opening on one side of the limiting plate is smaller than the other end of the movable sleeve, and the side in contact with the metal bellows is made of rubber, requiring manual pushing to move.

[0010] Preferably, the slot is hook-shaped and is used to rotate and engage with the magnetic head.

[0011] Preferably, the fixing belt includes a fixing ring, a connecting belt, and a limiting frame, and the three are fixedly connected; the fixing ring is fixedly disposed on the side of the mounting ring away from the limiting ring, and the connecting belt and the limiting frame are respectively located on both sides of the fixing ring.

[0012] Preferably, the fixing ring, connecting strap, and limiting frame are all made of elastic soft rubber, and the connecting strap can pass through the limiting frame; the metal corrugated tube can be manually wound and fixed by binding with the connecting strap.

[0013] Preferably, a plurality of rubber protrusions are fixedly provided on the surface of the connecting strip, and the rubber protrusions are arranged in a trapezoidal shape.

[0014] Preferably, a circular groove is provided between two adjacent rubber protrusions, and a plurality of rubber balls are fixedly provided at the end of the connecting band away from the fixing ring; the rubber balls can be manually pressed and locked into the circular groove to achieve fixation.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes the synergistic effect of a movable sleeve and a fixing strap to achieve flexible adjustment during use and stable fixation during storage, solving the storage problem of traditional telescopic pickups. During use, the movable sleeve's slot is rotated to separate from the round rod of the magnetic head, opening the entire device. After use, the metal corrugated tube is wrapped around the device, and the fixing strap, along with the engagement of the rubber ball and the round groove, achieves quick fixation, ensuring stable and reliable operation and storage. The elastic soft rubber material provides appropriate tension to prevent deformation. Furthermore, its simple operation greatly improves efficiency, solving problems such as rebound loosening and cumbersome operation, making it particularly suitable for industrial operation scenarios requiring frequent deployment and retrieval.

They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0022] It is understood that the term "a" should be understood as "at least one" or "one or more," that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0023] Please see Figures 1-4 A small magnetic pickup includes a magnetic head 1, a metal bellows tube 2, a rubber handle 3, two round rods 11 fixedly mounted on the magnetic head 1, a movable sleeve 4 sleeved on the rubber handle 3 for engaging with the round rods 11, and a fixing strap 5 located at one end of the rubber handle 3 for winding, storing and fixing the metal bellows tube 2. Two round rods 11 are circumferentially distributed at the end of the magnetic head 1 away from the metal bellows 2. Limiting rings 21 and mounting rings 22 are fixedly installed at both ends of the metal bellows 2 to limit the movement trajectory of the moving sleeve 4. The moving sleeve 4 is annular and has a slot 41 on its outer wall. A limiting plate 42 is fixedly installed at the end of the moving sleeve 4 away from the slot 41. The opening on one side of the limiting plate 42 is smaller than that on the other side of the moving sleeve 4, and the side that contacts the metal bellows 2 is made of rubber. It needs to be manually pushed to move. The slot 41 is hook-shaped and is used to rotate and engage with the magnetic head 1. Traditional telescopic pickups rely on the elasticity of the metal tube, which can easily extend again after retraction. This device, however, actively restrains the metal bellows 2 using a fixing strap 5 and a movable sleeve 4, ensuring compact storage. During use, the length of the metal bellows 2 is first adjusted according to the specific application scenario. After adjustment, the fixing strap 5 secures it, preventing excess length from affecting usability. After use, the metal bellows 2 can be manually wound and stored. Simultaneously, the movable sleeve 4 is manually pulled to move it towards the limiting ring 21, thus moving one side of the slot 41 out of the rubber handle 3. This allows it to rotate and engage with the magnetic head 1, fixing the round rod 11 along the track of the slot 41. This secures and stores the magnetic head 1 and the rubber handle 3, providing protection for the magnetic head 1 and a degree of storage. The movable sleeve 4 is stabilized by the friction of the limiting plate 42 and the rubber material, requiring manual pushing to move and prevent accidental slippage. The hook-shaped design of the slot 41 ensures a secure engagement with the round rod 11, preventing loosening during use.

[0024] The fixing strap 5 includes a fixing ring 51, a connecting strap 52, and a limiting frame 53, which are fixedly connected. The fixing ring 51 is fixedly located on the side of the mounting ring 22 away from the limiting ring 21. The connecting strap 52 and the limiting frame 53 are located on both sides of the fixing ring 51. The fixing ring 51, the connecting strap 52, and the limiting frame 53 are all made of elastic soft rubber, and the connecting strap 52 can pass through the limiting frame 53. The metal corrugated tube 2 can be manually wound and fixed by binding with the connecting strap 52. Multiple rubber protrusions 521 are fixedly provided on the surface of the connecting strip 52. The rubber protrusions 521 are arranged in a trapezoidal shape. A circular groove 522 is provided between two adjacent rubber protrusions 521. Multiple rubber balls 523 are fixedly provided at the end of the connecting strip 52 away from the fixing ring 51. The rubber balls 523 can be manually pressed and locked into the circular groove 522 to achieve fixation. The fixing strap 5 of this small magnetic pickup consists of a fixing ring 51, a connecting strap 52, and a limiting frame 53. Made of elastic soft rubber, it features a self-locking function, effectively securing the wound metal corrugated tube 2. This solves the problem of traditional magnetic pickups easily loosening after storage. The metal corrugated tube 2 is manually bent and wound around the rubber handle 3 to form a compact ring structure. The connecting strap 52 is then passed through the limiting frame 53, tightened, and the rubber ball 523 is pressed to embed it into the circular groove 522, achieving self-locking and preventing the fixing strap 5 from loosening due to vibration or external force. The limiting frame 53 guides the connecting strap 52 through the groove, ensuring a smooth binding process. The elastic soft rubber material provides moderate tension, ensuring both tightness and preventing excessive stretching and deformation, ensuring stable storage. The unidirectional insertion and pressing of the connecting strap 52 simplifies the binding process, eliminating the need for repeated adjustments and improving efficiency. It significantly enhances the storage stability and ease of operation of the metal corrugated tube 2, overcoming the shortcomings of traditional fixing methods such as easy loosening and cumbersome operation. It is suitable for high-frequency industrial applications.

The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
