[0025] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.
[0026] refer to Figure 1A duct insulation nail collection device includes a panel body 1 and a handle 2. The panel body 1 is hinged to one end of the handle 2. A magnetic strip 1.1 is provided on the panel body 1. The panel body 1 is also detachably provided with a movable roller 5. A battery pack 3 is provided on the handle 2. The battery pack 3 is electrically connected to the magnetic strip 1.1.
[0027] With the above setup, the magnetic method for collecting duct insulation nails can improve efficiency, avoid omissions, and greatly reduce the burden on workers; in addition, the panel body, handle, etc. are all detachable, which makes it easy to assemble when in use and disassemble, fold and store when not in use, making it easy to carry.
[0028] The magnetic strips 1.1 are evenly distributed on the bottom of the panel body 1. The evenly distributed magnetic strips provide a uniform and strong attraction, preventing the insulation nails on the ground from being missed.
[0029] refer to Figure 2 The battery pack 3 is equipped with Velcro 4, which can be wrapped around the handle 2. The Velcro 4 allows the battery pack to be detached for easy carrying and replacement.
[0030] refer to Figure 3 The handle 2 is composed of multiple short rods 2.1 connected end to end. One end of each short rod 2.1 has a threaded post, and the other end has a threaded hole that matches the threaded post. This design allows the handle to be easily disassembled into multiple short rods for convenient storage.
[0031] refer to Figure 4 The movable roller 5 includes a roller body 5.1, a U-shaped plate 5.2, and a wing screw 5.3. The edge of the panel body 1 is located within the opening of the U-shaped plate 5.2. The upper end of the roller body 5.1 is fixedly mounted on the lower end of the U-shaped plate 5.2 and abuts against the panel body 1. The upper end of the U-shaped plate 5.2 has a threaded hole, and the wing screw 5.3 is located within the threaded hole and abuts against the panel body 1. This design allows for quick disassembly and installation of the roller body, and the wing screw can be tightened by hand without the need for tools, making it convenient and fast.
[0032] The panel body 1 is composed of multiple individual panels 1.2 assembled sequentially, and the individual panels 1.2 are connected by slots. Due to the large size of the panel, it also adopts a detachable design for easy storage. The slot connection eliminates the need for cumbersome parts, ensuring reliable and stable operation.
[0033] The method used in this device is as follows:
[0034] 1) The handle uses a threaded connection and can be assembled to the required length according to the needs of the site. The main body of the panel uses a slot connection and can be assembled to the required width according to the actual situation on site. The external battery uses Velcro, which can be pasted at the corresponding height as needed, or it can be removed and carried. The movable rollers are clip-on type and can also be removed as needed.
[0035] 2) Place the device on the ground with the movable wheels close to the person and the head slightly tilted up;
[0036] 3) Adjust the handle angle, turn on the battery switch to magnetize the magnetic strip, and push the device along the fixed path to make the insulation nails adhere to the bottom;
[0037] 4) Turn off the battery, the magnetic strip will be demagnetized, and the adsorbed insulation nails will be automatically removed.
[0038] 5) After use, the device can be disassembled, folded together, and placed in a backpack for easy carrying.
