Detailed Description
The following detailed description and technical contents of the present invention will be described with reference to the drawings, which are provided for illustrative purposes only and are not intended to limit the present invention.
The present invention provides a corrosion-resistant magnetic wheel, as shown in fig. 1 to 3, which mainly comprises a shaft seat 10, a magnet ring 20, an anti-corrosion film 30, two sealing rings 40 and a side cover ring 50.
In the embodiment, the shaft seat 10 is made of plastic, but the utility model is not limited thereto, and for example, the shaft seat 10 may also be made of corrosion-resistant metal or other corrosion-resistant materials. The shaft seat 10 includes a base 11 and a shaft 12, the shaft 12 extends longitudinally from a side of the base 11. Specifically, the base 11 and the shaft 12 are both cylindrical and have the same axial center, and the diameter of the shaft 12 is smaller than that of the base 11. The axle seat 10 has an axle hole 13, and the axle hole 13 longitudinally penetrates through the base 11 and the axle 12, so that the axle seat 10 can be sleeved on a rotating shaft (not shown). The base 11 further has a positioning hole 14, the positioning hole 14 penetrates from the outer edge of the base 11 to the shaft hole 13, and a positioning member (not shown) is inserted into the positioning hole 14 to tightly press the rotating shaft to be fixed on the shaft seat 10. In the embodiment, the positioning hole 14 is a screw hole and the positioning element is a bolt, but the utility model is not limited thereto, and the positioning element may be a pin, for example. In addition, the shaft hole 13 may be a non-circular hole, so that the shaft seat 10 can be tightly fitted with the rotating shaft without slipping through the positioning member and the positioning hole 14.
The magnet ring 20 is a ring-shaped magnet, and the present invention does not limit the magnetic properties of the magnet, so that the designer can adjust the magnet according to different requirements. The magnet ring 20 is sleeved on the shaft 12. The magnet ring 20 has an outer annular surface 21 and two opposite side flat surfaces 22, and the outer annular surface 21 is connected between the two side flat surfaces 22.
The etching resist 30 covers the outer annular surface 21 and shields at least a part of each side flat surface 22. In the present embodiment, the etching-resistant film 30 may be a protective layer formed by an organic coating, an inorganic coating, a metal coating, a surface hardening treatment, a cathodic treatment, an anodic treatment, or the like, but the present invention is not limited thereto as long as the corrosion of corrosive chemical substances can be effectively prevented, and the designer may adjust the composition, thickness, and the like of the etching-resistant film 30 according to the requirements of different working environments.
The sealing rings 40 are disposed on the shaft 12 and located on the left and right sides of the magnet ring 20, and the sealing rings 40 are in contact with the etching resist 30 on the side planes 22. In the embodiment, the sealing ring 40 is an O-ring, but the utility model is not limited thereto.
The side cover ring 50 is locked on the shaft 12 and urges the sealing rings 40 and the magnet ring 20 longitudinally toward the base 11 so that the sealing rings 40 are tightly clamped on the etching resist 30 of the side planes 22. In the embodiment, the side cover ring 50 is a plastic part, but the utility model is not limited thereto, for example, the side cover ring 50 may also be made of a corrosion-resistant metal or other corrosion-resistant materials, and the side cover ring 50 and the shaft seat 10 are preferably made of the same material for convenient production, manufacture, and assembly. The inner edge of the side cover ring 50 is provided with an internal thread 51, the end of the shaft 12 is provided with an external thread 15, and the internal thread 51 is screwed with the external thread 15 to lock the side cover ring 50 on the shaft 12. Preferably, a thread sealant a is coated on the surfaces of the internal thread 51 and the external thread 15, so that the internal thread 51 and the external thread 15 are completely sealed by the cured thread sealant a after screwing, thereby preventing corrosive chemicals from penetrating from the threads. The outer edges of the base 11 and the side cover ring 50 are respectively provided with two opposite clamping planes 16, 52, so that when the side cover ring 50 is locked on the shaft rod 12, the clamping planes 16, 52 can be clamped by a tool (such as pliers) to facilitate the force application and locking.
To explain further, the base 11 is recessed with an annular groove 17 on the side where the shaft 12 extends, and the side of the side cover ring 50 facing the base 11 is recessed with another opposite annular groove 53. The sealing rings 40 are received in the annular grooves 17, 53, respectively, such that the sealing rings 40 are not directly exposed to corrosive chemicals.
It is noted that the magnet ring 20 has a thickness t, each sealing ring 40 has a diameter D, and each annular groove 17, 53 has a width w and a depth D. In the present embodiment, the width w is greater than the diameter D, and the diameter D is greater than the depth D, whereby the sealing rings 40 protrude out of the annular grooves 17, 53, so that the magnet ring 20 can contact the sealing rings 40 to be longitudinally pressed when the side cover ring 50 is locked, thereby elastically deforming the sealing rings 40. The etching resist 30 has a shielding length l shielding the side plane 22. The sum of the shielding length l and the width w 1/2 is greater than the thickness t, thereby ensuring that each seal ring 40 abuts against the etching resist 30 to achieve a sealing effect, and preventing corrosive chemicals from penetrating between the etching resist 30 and the seal ring 40 to corrode the magnet ring 20. In the embodiment, the shielding length l is equal to the thickness t of the magnet ring 20, but the utility model is not limited thereto.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the utility model as defined in the appended claims.
