Description

Technical Field

[0001] This utility model relates to a grinding device, specifically a portable hockey blade grinder. Background Technology

[0002] Ice hockey blades have a relatively thick blade, usually made of high-strength stainless steel, to ensure they won't easily break during high-speed skating and intense competition. The blade is designed with a right angle to suit the characteristics of ice hockey, which requires athletes to move quickly, stop abruptly, and turn sharply on the ice; therefore, the right angle design provides better stability and control.

[0003] Sharpening ice hockey blades has traditionally involved large grinding machines operated by skilled technicians, resulting in significant costs and time consumption. Therefore, current technology lacks a portable and easily operable ice hockey blade sharpening machine to reduce the cost and time required for sharpening. Utility Model Content

[0004] This invention aims to provide a portable ice hockey blade grinder. Compared with existing technologies, it reduces the grinding cost and time of ice hockey blades, and is simple to operate, requiring no professional personnel. On the one hand, it allows for the grinding and maintenance of ice hockey blades during breaks in games, providing a better on-ice experience; on the other hand, it reduces the expenses of ice hockey enthusiasts in ice hockey blade maintenance, encouraging more people to participate in the sport.

[0005] The technical solution of this utility model is as follows: A portable hockey blade grinder includes a housing, a motor is disposed inside the housing, and a power interface is provided on the housing for connection to the motor via a wire. The output shaft of the motor extends from one end of the housing, and a grinding wheel and an adjustment bolt for limiting the position of the grinding wheel are threadedly connected to the portion of the output shaft extending out of the housing.

[0006] The grinding wheel is covered by a protective cover fitted on the housing. The protective cover has a guide groove that faces the working surface of the grinding wheel, and the grinding wheel can grind the hockey blade that slides through the guide groove.

[0007] Furthermore, the inner wall of the protective cover is provided with at least two guide wheel sets along the length of the guide groove, wherein each guide wheel set includes two guide wheels located on both sides of the guide groove and facing each other.

[0008] Furthermore, the housing includes a housing body, one end of which is connected to a back cover by a snap or glue, and the other end forms a connecting part;

[0009] The protective cover is fitted onto the connecting part with an interference fit, and the connecting part has three oblong holes. The oblong hole in the middle is used to accommodate the output shaft of the motor, and the oblong holes on both sides are connected to the motor by screws.

[0010] Furthermore, the cross-section of the connecting part is rectangular, wherein the three waist-shaped holes are arranged parallel to the long side of the rectangle;

[0011] After the protective cover is fitted with the connecting part, the guide groove on the protective cover is parallel to the short side of the rectangle.

[0012] Furthermore, the power interface is located at the center of the bottom surface of the rear cover.

[0013] Furthermore, the bottom surface of the rear cover is also provided with heat dissipation vents.

[0014] Preferably, a waterproof rubber plug is provided at the power interface, the waterproof rubber plug including a plug body and a rubber cap connected to the plug body by a soft rubber band.

[0015] Furthermore, it also includes a motor speed controller, the input of which is connected to the mains power and the output of which is plugged into a power interface. Attached Figure Description

Detailed Implementation

[0025] like Figures 1-8 As shown, a portable hockey blade grinder includes a housing 1, in which a motor is installed. The housing 1 has a power interface 2 connected to the motor via a wire. A motor speed controller 9 supplies power to the motor through the power interface 2 and can adjust the motor's rotation speed. The output shaft 3 of the motor extends from one end of the housing 1, and the portion of the output shaft 3 extending out of the housing 1 is threadedly connected to a grinding wheel 4 and an adjusting bolt 5 that limits the position of the grinding wheel 4.

[0026] The grinding wheel 4 is covered by a protective cover 6 fitted on the housing 1. The protective cover 6 has a guide groove 7 that faces the working surface of the grinding wheel 4. The grinding wheel 4 can grind the hockey blade that slides through the guide groove 7.

[0027] In order to facilitate the positioning of the hockey blade in the grinding state, the inner wall of the protective cover 6 is provided with at least two guide wheel sets along the length of the guide groove 7, wherein each guide wheel set includes two guide wheels 8 located on both sides of the guide groove 7 and facing each other.

[0028] To facilitate the maintenance and upkeep of the motor, the housing 1 of this utility model specifically includes a housing body 100. One end of the housing body 100 is connected to a rear cover 110 by a buckle or glue, and the other end forms a connecting part 120. In order to adjust the distance between the grinding wheel 4 and the guide groove 7, three oblong holes 130 are provided on the connecting part 120. The oblong hole 130 in the middle is used to accommodate the output shaft 3 of the motor, and the oblong holes 130 on both sides are connected to the motor by screws to fix the motor.

[0029] To ensure a secure connection between the cover 6 and the housing 1, the cover 6 is fitted onto the connecting part 120 with an interference fit, but this is not a limitation; snap-fit ​​or bolt connection methods can also be used.

[0030] To further improve operational convenience, the connecting part 120 has a rectangular cross-section, with the three waist-shaped holes 110 arranged parallel to the long side of the rectangle. After the cover 6 is fitted onto the connecting part 120, the guide groove 7 on the cover 6 is parallel to the short side of the rectangle. This arrangement ensures that the guide groove 7 can only be located at both ends of the waist-shaped holes 110, facilitating quick positioning of the mating direction between the guide groove 7 and the grinding wheel 4. Furthermore, to ensure that the mating direction between the guide groove 7 and the grinding wheel 4 is unique, an indicator mark can be provided on the housing body 100 or the connecting part 120, or a strip-shaped groove or protrusion can be formed on at least one side of the connecting part 120, and a strip-shaped protrusion or groove corresponding to the aforementioned strip-shaped groove or protrusion can be formed on the corresponding inner wall of the cover 6.

[0031] In this embodiment, the power interface 2 is located at the center of the bottom surface of the rear cover 110, and the bottom surface of the rear cover 110 is also provided with heat dissipation holes 140 for heat dissipation of the motor.

[0032] In this embodiment, and based on protection considerations, a waterproof rubber plug 150 is provided at the power interface 2 on the back cover 110. The waterproof rubber plug 150 includes a rubber plug body and a rubber cap connected to the rubber plug body by a soft rubber band. When the rubber cap is inserted into the rubber plug body, it forms a sealed space that can completely cover the power interface 2.

[0033] The working principle of this utility model is briefly described below:

[0034] Adjust the position of the grinding wheel 4 on the output shaft 3 and the position of the output shaft 3 in the middle waist-shaped hole 110, and fasten the protective cover 6 so that the guide groove 7 is facing the working surface of the grinding wheel 4; slide the hockey knife through the guide groove 7 under the constraint of the guide wheel 8, and the grinding wheel 4 contacts the blade of the hockey knife and grinds the blade to ensure the perpendicularity of the blade. The setting of the guide groove 7 can effectively prevent the hockey knife from being over-grinded, thereby increasing the service life of the hockey knife.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any equivalent substitutions and modifications made by those skilled in the art without departing from the guidance of the present utility model shall be deemed to fall within the protection scope of the present utility model.
