Abstract

The invention relates to a portable knife sharpener for an ice skates, which aims to provide a knife sharpener capable of conveniently carrying the ice skates on an ice skating site and realizing a sharpening method of a skater through a simple operation school. The invention comprises a base, a rolling bearing, a bearing height adjusting washer, a bearing fixing nut, a chip removing brush, a grinding plate fixing nut, a pressure spring, a grinding plate fixing screw rod, a grinding plate gasket, a bearing fixing adjusting window and a handle. When the ice skates are used, the knife edge of the single ice skates is held upwards, the knife grinder rolling bearing clamps the knife board downwards, the knife edge is attached to the grinding board, the knife board is pressed downwards with a little force and slides forwards and backwards, and the grinding board can grind the special knife edge of the ice skates with straight two sides at 90-degree right angles on the knife edge.

Description

Portable quick-sliding skates knife sharpener

Technical Field

The invention relates to a knife sharpening device, in particular to a portable quick skating knife sharpening device.

Background

The skates of the current speed skating are sharpened by two sharpening devices, one is an electric sharpener and the other is a fixed frame type sharpener, and the two sharpening devices are inconvenient to carry due to large volume and inconvenient to use in the environment of an outdoor skating rink, and can only be used indoors and by people with certain operation technology.

Disclosure of Invention

The invention overcomes the defects of the prior art and provides the portable speed skating skates sharpener with simple operation.

The technical scheme of the invention is as follows: the portable quick-sliding skates sharpener comprises a base, a rolling bearing, a bearing height adjusting washer, a bearing fixing nut, a chip removing brush, a grinding plate fixing nut, a pressure spring, a grinding plate fixing screw rod, a grinding plate gasket, a bearing fixing adjusting window and a handle. The base is a section of square pipe, the center point of the base panel is transversely provided with two parallel rolling bearing mounting holes, the panel of the center point of the mounting positions of the grinding plates at the left side and the right side of the bearing mounting holes and the opposite bottom plate are provided with the grinding plate mounting holes, and the position of the base bottom plate opposite to the panel rolling bearing mounting holes is provided with bearing fixing and adjusting windows.

The rolling bearings are bolt type roller needle bearings or bearings fixed by bolts, two rolling bearings are combined, the rolling bearings are fixed on a panel of the base by taking the thickness of the ice skates as the mutual distance, and two grinding plates fixed on the panel of the base left and right form a linear plane sliding rail grinder.

The bearing height adjusting washer consists of a plurality of thin washers, and the height of the bearing on the panel can be adjusted.

The bearing fixing nut is a nut for fixing the bearing on the panel and has the function of adjusting the distance between the bearings.

The dust removing brushes are four brushes fixed between the rolling bearing and the grinding plate.

The grinding plate is a square or round diamond grinding disc (only square and round are drawn in the drawing), two plates are in a group, and the grinding plate is fixed on the panel in a shaft fixing mode through a fixing nut, a pressure spring and a screw rod which are fixed at the center of the grinding plate, so that the grinding plate can horizontally rotate on the panel to balance the abrasion of the grinding plate.

The grinding plate gasket consists of a plurality of narrow thin sheets with the length equal to the grinding plate width, and is arranged below the grinding plate far-end plate and used for adjusting the radian required by grinding the cutting edge.

The bearing fixing and adjusting window is a larger hole formed in the installation position of the rolling bearing on the corresponding panel of the bottom plate.

The handle is a handle mounted on the base plate.

By adopting the technical scheme, the quick skates provided by the invention have the following beneficial effects:

1. compared with the existing knife sharpener, the volume is miniaturized, and the finished product can be placed in a small storage bag or a pocket in the ice skates bag for carrying.

2. The ice skate blade sharpening machine is convenient and simple to use, does not need special personnel and sites, can be used for sharpening on site, does not need the process of fixing the ice skate blade on the tool rest and then disassembling the ice skate blade after sharpening, and saves time.

3. The grinding plate is matched with the grinding plate gasket to grind the straight or radian-required cutting edge.

Detailed Description

The invention is described in detail below with reference to the attached drawing figures:

FIG. 1 is a front view of the present invention

FIG. 2 is a cross-sectional view of a rolling bearing fixing portion in the present invention

FIG. 3 is a cross-sectional view of the attachment of the grind plate in the present invention

FIG. 4 is a view of the midsole of the present invention

Referring first to fig. 1: the plane of the base (1) of the portable quick skates sharpener is formed by two rolling bearings (2) vertically fixed on a panel and two sharpening plates (3) with two sides of the bearings also fixed on the panel, when in practical use, the skates blade is upward, the skates blade is clamped between the two bearings, the sharpener presses the sharpening plates on the blade to reciprocate under certain pressure, the requirement that the two sides of the front plane of the sharpening blade are at a standard 90-degree right angle is met, and the possible adhered abrasive dust on the sharpening plates is brushed off by a dust removing brush (4) fixed between the rolling bearings and the sharpening plates, so that the abrasion dust is prevented from damaging the bearing surface and the sharpening plates.

Fig. 2 is a cross-sectional view of the rolling bearing fixed to the panel, the bottom side height of the bearing being adjusted to be about 1 mm higher than the grinding plate by the bearing height adjusting washer (5) and fixed to the panel by the rolling bearing fixing nut (6) at a pitch of the thickness of the knife plate.

Fig. 3 is a cross-sectional view of a grinding plate fixed on a base, upper and lower opposite mounting holes are formed on a panel and a bottom plate at positions opposite to a grinding plate fixing nut (7), a pressure spring (9) penetrates through a screw rod (8), the screw rod penetrates through the bottom plate and is screwed on the grinding plate fixing nut to form shaft fixing, the grinding plate can be subjected to plane conversion at any angle under the fixing, the purpose of balancing the abrasion degree of each part of the grinding plate is achieved, and the structure is also beneficial to quickly replacing different grinding plates.

In the bottom view of fig. 4, a bearing fixing and adjusting window (11) is arranged at the mounting position of the bottom plate corresponding to the rolling bearing, and the bearing spacing is fixed and finely adjusted through the window so as to adapt to the requirements of different blade thicknesses, and a handle (10) is also arranged on the bottom plate, so that the knife sharpener can be conveniently operated.
