Description

Technical Field

[0001] This utility model relates to the field of construction tools technology, specifically to a magnetic pickup tool. Background Technology

[0002] On construction sites, various small iron parts are widely used for connection and fixation. However, due to their small size, these parts are very easy to fall off during construction. Once fallen, they are not only difficult to find, but the iron parts left on the ground may also puncture the tires of construction vehicles or damage the building structure, thus wasting building materials and affecting construction safety.

[0003] Chinese patent CN215942900U discloses a "simple and portable magnetic picking tool for construction sites." This device solves the problem of cumbersome and inefficient picking of small ferrous parts in existing technologies by placing magnets inside the outer casing and adjusting the magnet's attraction force by moving the handle up and down. However, the outer casing is fixed, preventing users from disassembling and replacing the internal magnets. Furthermore, the magnets' attraction force gradually weakens after prolonged use, leading to decreased work efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a magnetic picking tool to solve the problem that the existing magnetic picking tools have a fixed outer box, which makes it impossible to disassemble and maintain the internal magnets, resulting in a decrease in work efficiency after long-term use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A magnetic pickup tool, comprising: The adsorption box has an opening at the top, and a slot is provided on the inside of the opening; A mounting plate is detachably mounted on the opening, and a mounting rod is provided on the mounting plate. A pull rod is slidably provided inside the mounting rod, and one end of the pull rod passes through the mounting plate and is threadedly connected to a magnet. The mounting plate has a mounting groove, and the snap-fit ​​assembly is slidably disposed in the mounting plate so that it snaps into the groove by sliding the snap-fit ​​assembly, thereby fixing the mounting plate to the opening of the adsorption box and positioning the magnet at the bottom end of the adsorption box.

[0006] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting an opening at the top of the adsorption box and using a detachable mounting plate and snap-fit ​​assembly, the adsorption box can be quickly disassembled and assembled, allowing the internal magnets to be easily removed and replaced. This solves the problem of the existing technology where the outer box is a fixed structure and the magnets cannot be maintained, and greatly extends the service life of the device.

[0007] Furthermore, the mounting groove is provided with a sliding groove, and the snap-fit ​​assembly includes a sliding plate slidably disposed in the sliding groove, a snap-fit ​​block disposed in the sliding plate, and an adjusting member, so that the adjusting member drives the sliding plate to slide on the sliding groove, so that the snap-fit ​​block snaps into the snap-fit ​​groove, or separates from it.

[0008] Furthermore, the adjusting component includes a rotating disk rotatably disposed in the mounting groove, a guide wheel, and a traction rope. The rotating disk and the guide wheel are spaced apart. One end of the traction rope is disposed on the bottom outer wall of the rotating disk, and the other end is connected to the outer wall of the slide plate through the guide wheel.

[0009] Furthermore, the traction rope is fitted with a first spring, the two ends of which abut against the inner walls of the slide plate and the chute, respectively.

[0010] Furthermore, the card block has a guide arc surface on the side facing the opening.

[0016] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0017] In the description of this utility model, it should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and to facilitate understanding and reading. They are not intended to limit the implementation conditions of this utility model and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives of this utility model, should still fall within the scope of the technical content disclosed in this utility model.

Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model.

[0018] like Figure 1-4 As shown in the figure, this utility model embodiment proposes a magnetic pickup tool, including: an adsorption box 10 with an opening at the upper end and a slot 11 provided on the inner side of the opening; a mounting plate 20, detachably mounted on the opening, and a mounting rod 30 provided on the mounting plate 20, a pull rod 40 slidably provided in the mounting rod 30, one end of the pull rod 40 passing through the mounting plate 20 and threadedly connected to a magnet 50; and a snap-fit ​​assembly 60, in which the mounting plate 20 has a mounting groove 21, and the snap-fit ​​assembly 60 is slidably disposed in the mounting plate 20 so that by sliding the snap-fit ​​assembly 60, it snaps into the slot 11, thereby fixing the mounting plate 20 to the opening of the adsorption box 10 and positioning the magnet 50 at the bottom end of the adsorption box 10.

[0019] In this embodiment of the utility model, before use, the mounting plate 20 is first installed at the opening of the adsorption box 10 by the snap-fit ​​component 60. After the snap-fit ​​component 60 slides into the slot 11, the mounting plate 20 can be firmly fixed at the upper end of the adsorption box 10, and the magnet 50 is located at the bottom of the adsorption box 10, thereby completing the assembly of the device.

[0020] During use, when picking up small iron parts from the ground, the user holds the mounting rod 30 so that the bottom of the adsorption box 10 is close to the ground. At this time, the magnet 50, under the action of adsorption force, attracts the scattered iron parts to the outer wall of the adsorption box 10, thus completing the collection of iron parts. As the number of items picked up increases, once a certain amount of iron parts has been adsorbed onto the outer wall of the adsorption box 10, the user can pull the lever 40 to slide the magnet 50 upwards along the mounting rod 30, gradually moving it away from the adsorbed iron parts. As the distance between the magnet 50 and the iron parts increases, the magnetic attraction gradually weakens until it disappears. At this point, the iron parts will automatically fall off, thus completing the release of the iron parts.

[0021] When magnet 50 needs to be replaced, the user simply pushes the snap-fit ​​assembly 60 to separate it from the slot 11, allowing the mounting plate 20 to be removed from the opening of the adsorption box 10. Then, the magnet 50 is loosened from the pull rod 40, thus allowing for its replacement. This process is simple in structure and easy to operate, effectively avoiding the shortcomings of existing technologies where magnet 50 cannot be maintained or replaced, thereby improving the device's lifespan and working efficiency.

[0022] Specifically, such as Figure 3-4 As shown in this embodiment of the invention, the mounting groove 21 is provided with a sliding groove 22, and the snap-fit ​​assembly 60 includes a sliding plate 61 slidably disposed on the sliding groove 22, a snap-fit ​​block 62 disposed on the sliding plate 61, and an adjusting member. The adjusting member drives the sliding plate 61 to slide on the sliding groove 22, so that the snap-fit ​​block 62 snaps into or separates from the snap-fit ​​slot 11. In use, the adjusting member drives the sliding plate 61 to slide along the sliding groove 22, thereby driving the snap-fit ​​block 62 to move synchronously, so that it snaps into the snap-fit ​​slot 11 at the opening of the adsorption box 10, so that the mounting plate 20 is securely limited to the upper end of the adsorption box 10. When disassembly is required, the user only needs to reverse the adjusting member to make the sliding plate 61 slide in the reverse direction in the sliding groove 22, and the snap-fit ​​block 62 can be separated from the snap-fit ​​slot 11, thereby releasing the limitation on the mounting plate 20 and realizing the quick disassembly and assembly of the mounting plate 20.

[0023] Specifically, such as Figure 4As shown in this embodiment of the utility model, the adjusting component includes a rotating disk 63 rotatably disposed in the mounting groove 21, a guide wheel 64, and a traction rope 65. The rotating disk 63 and the guide wheel 64 are spaced apart. One end of the traction rope 65 is disposed on the bottom outer wall of the rotating disk 63, and the other end is connected to the outer wall of the slide plate 61 through the guide wheel 64. In use, by rotating the rotating disk 63 inside the mounting slot 21, the outer wall of its bottom end causes the traction rope 65 to tighten or loosen. That is, under the guidance of the guide wheel 64, the traction rope 65 drives its other end to slide the slide plate 61 along the slide groove 22. When the slide plate 61 moves to the point where the locking block 62 is in contact with the locking slot 11, the locking block 62 can be inserted into the locking slot 11, thereby firmly limiting the mounting plate 20 at the opening of the adsorption box 10. When the rotating disk 63 is rotated in the opposite direction, the traction rope 65 drives the slide plate 61 to move in the opposite direction, causing the locking block 62 to disengage from the locking slot 11, thereby realizing the disassembly of the mounting plate 20. At the same time, in order to facilitate the operation of rotating the rotating disk 63, the mounting plate 20 is also provided with a knob, one end of which passes through the mounting plate 20 and is connected to the rotating disk 63.

[0024] Furthermore, the traction rope 65 is fitted with a first spring 66, the two ends of which abut against the inner walls of the slide plate 61 and the groove 22, respectively. Under the action of the first spring 66, the slide plate 61 is compressed, causing the locking block 62 to remain extended in the initial state. Thus, when the locking block 62 corresponds to the groove 11, releasing the rotating disk 63 will automatically cause the locking block 62 to extend into the groove 11 under the restoring force of the first spring 66, thereby improving the convenience of operation and the stability of the connection. Moreover, to further simplify the installation operation, the locking block 62 has a guide arc surface on the side facing the opening. When the mounting plate 20 is installed into the opening of the adsorption box 10, the adsorption box 10 will compress the guide arc surface of the locking block 62, causing the locking block 62 to retract into the groove 22 under pressure. Until the locking block 62 corresponds to the groove 11, under the action of the first spring 66, the locking block 62 will automatically embed into the groove 11, thereby completing the quick fixation.

[0025] It is worth mentioning that in this embodiment of the utility model, there are two slots 11, which are located on the left and right sides of the opening of the adsorption box 10, respectively. There are also two corresponding snap-fit ​​components 60, but the rotating disk 63 is set as one. By placing two traction ropes 65 on the two sides of the rotating disk 63, the two slide plates 61 can be driven to move towards or away from each other by rotating the rotating disk 63, so that the two snap-fit ​​blocks 62 can simultaneously snap into or disengage from the corresponding slots 11, thereby achieving the stable fixing or quick disassembly of the mounting plate 20.

[0026] Based on the above solutions, such as Figure 2As shown in this embodiment of the invention, a baffle 70 is provided on the outer side of the adsorption box 10. The baffle 70 forms an isolation zone on the adsorption box 10 to block iron parts adsorbed on the side wall of the adsorption box 10. Specifically, when the magnet 50 moves upward along the mounting rod 30 via the pull rod 40, the iron parts adsorbed on the side wall of the adsorption box 10 also move upward with the magnet 50 until they are blocked by the baffle 70 at the isolation zone. Subsequently, the magnet 50 continues to move away from the baffle 70, and as the distance increases, the magnetic attraction gradually weakens until it disappears. At this point, the iron parts lose the magnetic attraction and automatically detach at the baffle 70, thus releasing the iron parts.

[0027] Secondly, a fixing plate 41 is provided at one end of the pull rod 40 located in the adsorption box 10, and a second spring 80 is also sleeved on the pull rod 40. The two ends of the second spring 80 abut against the fixing plate 41 and the mounting plate 20, respectively. Under the action of the second spring 80, the pull rod 40 always has a downward restoring force, so that the magnet 50 can automatically return to the bottom position of the adsorption box 10 after the pull rod 40 is released, thus preparing for the next picking operation, thereby improving the continuous use efficiency and operation convenience of the tool.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
