Description

Technical Field

[0001] This invention relates to the field of ice sports equipment maintenance technology, and in particular to a quick-clamp electric ice blade sharpener. Background Technology

[0002] The sharpness of ice skates directly affects an athlete's skating speed, control stability, and competitive performance. With the popularization and development of ice sports, the daily maintenance and sharpening of ice skates has become an important task for athletes and sports equipment managers. Currently, ice skates are mainly sharpened manually. The skate holders used by operators are usually of a screw-on type, where the handle is turned to clamp the skate in place.

[0003] However, the above-mentioned threaded clamping structure has the following problems in actual use: the threaded clamping method requires the operator to turn the handle multiple times to clamp or release the ice skate, which is cumbersome. Especially when ice skates need to be frequently changed for batch grinding, it requires a lot of physical strength and time, which greatly affects work efficiency. During the grinding process, the clamping force is mainly maintained by the friction of the threads. Due to the different materials of the frame and the knob screw (the frame is made of aluminum alloy), long-term frequent rotation and friction can easily cause thread wear, resulting in derailment and rendering the machine unusable. A quick-clamp electric ice skate grinding machine is proposed to solve the above problems. Summary of the Invention

[0004] To overcome the above shortcomings, the present invention provides a quick-clamp electric ice skate grinder, which aims to improve the problems of cumbersome ice skate clamping operation, poor clamping stability and limited grinding accuracy in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick-clamp electric ice knife sharpener, comprising:

[0007] Frame;

[0008] An electric grinding assembly is assembled on the upper part of the frame;

[0009] Quick-release wrenches are installed on the left and right sides of the frame, respectively;

[0010] Ice skates are mounted at the clamp position of the frame;

[0011] The electric sharpening assembly includes a support grip plate, on the upper part of which two DC motors are mounted side by side; a control system is located between the two DC motors, and the control system integrates a switch, a power socket and a speed control knob.

[0012] The output drive end of the DC motor is fixedly equipped with a magnetic disk. Three protruding cylindrical magnets are evenly arranged on the bottom surface of the magnetic disk, and the grinding disc can be detachably attracted and fixed by magnetic force.

[0013] The support grip plate has an integrally formed fixed bracket at the center of its bottom surface.

[0014] As a further description of the above technical solution:

[0015] The quick-release wrench is driven by the movable clamp; the movable clamp is slidably mounted on the optical axis guide rail. Turning the quick-release wrench can drive the movable clamp to move along the optical axis guide rail, thereby opening and closing the clamp and completing the quick assembly and disassembly of the ice skates.

[0016] As a further description of the above technical solution:

[0017] The switch is used to control the synchronous start and stop of two DC motors; the power socket is used to connect an external power source to power the whole machine; the speed control knob can steplessly adjust the rotation speed of the DC motor; the protruding cylindrical magnet at the bottom of the magnetic disk can firmly attract and limit the grinding disc, preventing the grinding disc from shifting or falling off during the grinding process.

[0018] As a further description of the above technical solution:

[0019] The frame is fixedly mounted with a slide rail, and the slider is slidably mounted on the slide rail, which can slide back and forth along the length of the slide rail. Both ends of the slide rail are equipped with hand screws. Turning the hand screws at both ends can raise and lower the overall height of the slide rail, and simultaneously change the working height of the electric sharpening assembly, thereby adjusting the contact gap between the grinding disc and the ice blade edge, and changing the grinding contact resistance and friction area.

[0020] As a further description of the above technical solution:

[0021] The top of the slider is vertically fixed with a pin; the bottom of the fixed bracket has a matching pin insertion hole; during the grinding operation, the pin is inserted into the insertion hole, so that the electric grinding blade assembly is rigidly connected to the slider and moves back and forth linearly along the slide rail to grind the ice blade.

[0022] As a further description of the above technical solution:

[0023] The quick-release wrench adopts an elbow-type quick-clamp structure, which is hinged to the outside of the frame via a pivot. Pulling the handle of the elbow-type quick-clamp upwards releases the movable clamp; pulling the handle downwards locks the movable clamp, thus quickly securing the ice skate.

[0024] As a further description of the above technical solution:

[0025] Adjusting the height of the slide rail by hand-tightening the screws changes the working position of the electric sharpening assembly and grinding disc, adapting to ice skate blades with different wear levels and ensuring sharpening precision.

[0026] The present invention has the following beneficial effects:

[0027] 1. In this invention, an elbow-type quick clamp is used as a quick wrench, and the quick wrench is connected to the movable clamping jaw for transmission. When in use, simply pull the wrench up or down to drive the movable clamping jaw to slide along the optical axis guide rail, thereby realizing the quick opening and closing of the clamping jaw and quickly completing the loading and unloading of ice skates. Compared with the existing technology that uses a threaded knob to tighten for clamping, the clamping operation is simplified from multiple rotations to a single pull, which greatly improves the efficiency of loading and unloading ice skates.

[0028] 2. In this invention, by connecting the fixed bracket of the electric grinding tool assembly with the pin on the top of the slider through a plug-in engagement, the electric grinding tool assembly is connected to the slider through the fixed bracket during the grinding operation, and slides back and forth along the slide rail with the slider. The two motors rotate in opposite directions, thus achieving the stability of the grinding tool assembly running linearly along the slide rail during the grinding process.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example:

[0037] Reference Figures 1 to 4 A quick-clamp electric ice skate sharpening machine includes a frame 1, an electric sharpening assembly 2, a quick-clamp wrench 3, and ice skates 4. The frame 1 serves as the basic support structure of the entire machine and is made of metal, used to support and fix other components. The electric sharpening assembly 2 is located on the upper part of the frame 1 and is used to sharpen and trim the blades of the ice skates 4. The quick-clamp wrench 3 is installed on the outside of the frame 1 and is used to quickly clamp and release the ice skates 4. The ice skates 4 are mounted at the clamping position of the frame 1, with the blade to be sharpened facing upwards so as to contact the grinding disc 28 of the electric sharpening assembly 2.

[0038] Reference Figure 2 A slide rail 11 is fixedly installed on the frame 1, and a slider 12 is located on the slide rail 11 and can slide back and forth along the length of the slide rail 11; both ends of the slide rail 11 are equipped with hand screws 14 for adjusting the fitting gap between the grinding disc 28 and the ice blade edge; a pin 13 is vertically fixed on the top of the slider 12.

[0039] Reference Figure 3 and Figure 4 The electric sharpening assembly 2 includes a support grip plate 21, which serves as the grip base for the electric sharpening assembly 2. A DC motor 26 is mounted on the upper part of the support grip plate 21. A magnetic disk 27 is fixedly mounted on the output drive end of the DC motor 26. A grinding disc 28 is detachably attached to the bottom of the magnetic disk 27 by magnetic force. Protruding cylindrical magnets evenly arranged on the bottom surface of the magnetic disk 27 attract the grinding disc 28 to prevent the grinding disc from shifting or falling off during the sharpening process. A fixing seat 29 is integrally formed in the middle of the bottom surface of the support grip plate 21. The bottom of the fixing seat 29 has an insertion hole that matches the pin 13 on the top of the slider 12. During the sharpening operation, the pin 13 is inserted into the insertion hole of the fixing seat 29, so that the electric sharpening assembly 2 is rigidly connected to the slider 12. The electric sharpening assembly 2 can then move back and forth linearly along the slide rail 11 with the slider 12 to complete the sharpening of the ice skate blade.

[0040] Reference Figure 1 and Figure 2The quick-clamp wrench 3 adopts an elbow-type quick-clamp structure, which is hinged to the outside of the frame 1 via a pivot and is in transmission cooperation with the movable clamp 16. The movable clamp 16 is slidably mounted on the optical axis guide rail 15. When the operator pulls the handle of the quick-clamp wrench 3 upward, the clamping end disengages from the movable clamp 16, the clamp is released, and the ice skate 4 can be freely put on and taken off. When the handle is pulled downward, the clamping end presses against the movable clamp 16, the clamp is locked, and the ice skate 4 is quickly fixed. The entire clamping and releasing process can be completed with only a single operation.

[0041] When using this equipment to sharpen ice skates, first place the ice skate 4 in the clamp of the frame 1, so that the blade part of the ice skate 4 falls into the movable clamp 16, and adjust the ice skate alignment baffle to keep the blade edge parallel to the length direction of the slide rail 11; after confirming that the position is correct, pull down the handle of the quick clamp wrench 3 to firmly lock the ice skate 4 onto the frame 1; then, align the insertion hole at the bottom of the fixing bracket 29 of the electric sharpening assembly 2 with the pin 13 at the top of the slider 12 and insert it downwards to make the electric sharpening assembly 2 and the slider 12 drive connection; connect the external power supply through the power socket 24 and press the switch 23. The DC motor 26 is started, which drives the magnetic disk 27 and grinding disc 28 to rotate at high speed. The operator holds the support handle 21 and pushes the electric grinding blade assembly 2 at a constant speed along the length of the slide rail 11, so that the grinding disc 28 moves back and forth along the blade edge to complete the grinding and finishing of the blade edge. During the grinding process, the speed of the DC motor 26 can be adjusted by the speed control knob 25 to adapt to different hardness blade materials or different grinding precision requirements. After grinding is completed, the switch 23 is turned off, and the handle of the quick-release wrench 3 is pulled upward to release the movable clamp 16 and take out the ground blade 4.

[0042] When the ice skates wear down after long-term use and the height of the skates decreases, the height of the slide rail 11 can be lowered by rotating the hand-tightening screws 14 at both ends of the slide rail 11. This will cause the electric sharpening assembly 2 to descend, so that the grinding disc 28 fits the low-wear edge. For brand new or lightly worn ice skates, the height of the slide rail 11 can be raised by tightening the hand-tightening screws 14, raising the working position of the grinding disc 28 to accommodate ice skates with different levels of wear and ensure sharpening fit accuracy.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
