[0023] Example 1

[0024] Embodiment 1 of the utility model is a magnetic trolley for cleaning the floor of a monocrystalline silicon dust-free workshop, comprising a base 1 with wheels 7 on both sides and a pull rod 3 with a handle 2, wherein the pull rod 3 is movably connected to the surface of the base 1, wheels 7 are provided on both sides of the base 1 and a plurality of magnetic rods 5 are provided at the bottom of the base 1 for adsorbing magnetic materials on the ground.

[0025] Reference Figure 1 to Figure 2 The magnetic trolley in this embodiment includes a base 1, a pull rod 3 and a magnetic rod 5. The wheels 7 arranged on both sides of the base 1 can move freely. During the movement, the magnetic rod 5 at the bottom of the base 1 absorbs the magnetic material. The bottom surface of the magnetic rod 5 is higher than the bottom surface of the base 1, providing space conditions for the absorption of the magnetic material. The pull rod 3 is movably connected to the base 1, and the pull rod 3 rotates 180° above the base 1, so that the pull rod 3 can be adjusted at multiple angles to meet the cleaning of different floors, making it flexible and convenient to use, and avoiding workers from bending over or squatting on the ground for cleaning operations.

[0026] The length, width and height of the base 1 are 345mm-355mm, 215mm-225mm and 85mm-95mm respectively, and the length of the pull rod 3 is 850mm-950mm. The overall shape is flexible and compact. The base 1 is square-shaped, and the magnetic rods 5 are evenly distributed in the base 1, so that every corner of the workshop can be thoroughly cleaned. At the same time, the pull rod 3 conforms to ergonomics, avoiding workers from bending or squatting, thereby improving cleaning efficiency. At the same time, the pull rod 3 can also be a telescopic rod to meet different needs and improve the utilization rate of the pull rod 3.

[0027] In some preferred embodiments, a plurality of partition plates 11 are provided inside the base 1, a plurality of first through holes 12 are provided at the bottom of the base 1 and the partition plates 11, each first through hole 12 is parallel to each other, a sleeve 4 is provided in the plurality of transversely arranged first through holes 12, and the magnetic rod 5 is located in the sleeve 4.

[0028] Reference Figure 3 and Figure 4 The partition plate 11 divides the interior of the base 1 into multiple accommodating spaces, and is provided with multiple first through holes 12. The first through holes 12 in the base 1 and the partition plate 11 mainly provide assembly conditions for the installation of the sleeve 4. The magnetic bar 5 is in the sleeve 4 to avoid direct contact between the magnetic bar 5 and the magnetic material on the workshop floor, while not affecting the magnetic effect on the magnetic material on the floor, so as to facilitate the cleaning and collection of the magnetic material adsorbed in the magnetic trolley. The first through hole 12 set in the partition plate 11 is also used to evenly distribute the pressure for the installation of the sleeve 4 and the magnetic bar 5, to avoid bending caused by the absorption of more magnetic materials in the middle of the sleeve 4 and the magnetic bar 5, and to extend the service life of the sleeve 4 and the magnetic bar 5.

[0029] In some preferred embodiments, a first through groove 120 perpendicular to the magnetic rod 5 is provided on one side of the base 1, and a second through groove 121 is provided on the inner wall of the first through hole 12 in the base 1. The first through groove 120 and the second through groove 121 are on the same horizontal line, and the first through groove 120 and the second through groove 121 are interspersed with a blocking bar 6, and the blocking bar 6 and the magnetic rod 5 are perpendicular to each other.

[0030] In this embodiment, the first through groove 120 is located on both sides of the base 1, and the second through groove 121 is arranged in the inner wall of the first through hole 12 of the base 1. The second through groove 121 connects the first through hole 12 in the base 1, and the first through groove 120 and the second through groove 121 are on the same horizontal line. The end of the blocking strip 6 is passed through the first through groove 120, the first through hole 12 and the second through groove 121, and the short side of the base 1 is closed with a blocking strip 6 to prevent the sleeve 4 and the magnetic bar 5 from falling off from the first through hole 12 to the outside of the base 1.

[0031] In some preferred embodiments, a fixed shaft 13 is inserted between the two first through holes 12, and the fixed shaft 13 passes through both ends of the base 1. Both ends of the fixed shaft 13 are provided with mounting shafts 130, and the mounting shaft 130 has a slot 131. The wheel 7 is provided with a second through hole 70, and the mounting shaft 130 passes through the second through hole 70 after deformation to assemble the wheel 7.

[0032] Reference Figure 5 The wheel 7 provided in the present application is mainly assembled through the mounting shafts 130 at both ends of the fixed shaft 13. The fixed shaft 13 is located between the two first through holes 12, slightly above, and passes through both ends of the base 1. The two ends of the fixed shaft 13 are mounting shafts 130, and the ends of the mounting shaft 130 are provided with slots 131. When installing the wheel 7, it is only necessary to squeeze the mounting shaft 130. At this time, the slot diameter of the slot 131 becomes smaller. Keeping this state, it passes through the second through hole 70 of the wheel 7. After the hand is released, the deformed mounting shaft 130 moves outward, so that the outer peripheral surface of the mounting shaft 130 contacts the inner peripheral surface of the second through hole 70. At this time, the aperture of the slot 131 is smaller than the aperture when the wheel 7 is not assembled.

[0033] In some preferred embodiments, the outer diameter of the mounting shaft 130 is larger than the diameter of the second through hole 70. This is mainly because the mounting shaft 130 is more firmly assembled with the wheel 7 after deformation, and is also easy to disassemble.

[0034] In some preferred embodiments, a connecting block 10 is provided on the top of the base 1, protrusions 100 are provided at both ends of the connecting block 10, a U-shaped block 30 is provided at the bottom end of the pull rod 3, and the two protrusions 100 respectively pass through the two sides of the U-shaped block 30.

[0035] Reference Figure 2 and Figure 3 The connecting block 10 and the protrusions 100 at both ends thereof are assembled in the through holes preset on both sides of the U-shaped block 30, so as to realize the horizontal rotation of the pull rod 3 by 180°, adapt to the cleaning of ground magnetic materials in various situations, and improve the utilization rate.

[0036] In some preferred embodiments, the installation shaft 130, the fixed shaft 13 and the sleeve 4 are all made of plastic. The installation shaft 130 and the fixed shaft 13 are integrated, and the installation shaft 130 made of plastic can be slightly deformed, which is convenient for disassembly and assembly of the wheel 7, and convenient for taking out and cleaning the magnetic bar 5. At the same time, the magnetic bar 5 can be hidden by the wheel 7, which is beautiful and practical. The sleeve 4 made of plastic is sleeved on the outer periphery of the magnetic bar 5, which does not affect the magnetic absorption performance of the magnetic bar 5, and at the same time facilitates the removal and collection of magnetic substances outside the sleeve 4 to avoid damage to the magnetic bar 5 by the magnetic substances.

[0037] When the utility model is used, the pull rod 3 is connected with the connecting block 10, the protrusion 100 and the U-shaped block 30 to adjust the adaptation angle, hold the slightly curved handle 2, and the wheel 7 moves back and forth under the action of the pull rod 3 to move the base 1 to the magnetic material. The magnetic rod 5 absorbs the magnetic material on the ground through its own magnetic absorption property, so that the magnetic material is absorbed outside the sleeve 4. When cleaning the magnetic material in the sleeve 4, the wheel 7 is disassembled, the blocking strip 6 is taken out, and then the magnetic rod 5 is taken out. The magnetic material absorbed in the sleeve 4 will fall into the collection bucket, and then the magnetic rod 5, the blocking strip 6 and the wheel 7 are installed in turn for the next cleaning. The utility model assembles the U-shaped block 30 set at the bottom end of the pull rod 3 and the protrusions 100 at both ends of the connecting block 10 at the same time, so as to adjust the angles of different cleaning scenes without bending or squatting to work; the blocking strip 6 is used to limit the position of the magnetic rod 5 in the sleeve 4, and the magnetic rod 5 is located inside the sleeve 4 made of plastic material to absorb magnetic substances, thereby avoiding direct contact with the magnetic substances and causing metal wear on the surface of the magnetic rod 5, thereby extending the service life and achieving high demagnetization efficiency; the wheel 7 and the mounting shaft 130 are assembled in a snap-fit ​​manner, which is convenient for disassembly and assembly of the wheel 7.

[0038] The above is only a preferred embodiment of the utility model and does not limit the utility model in any form. According to the technical essence of the utility model, within the spirit and principles of the utility model, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the utility model.
