Description

Technical Field

[0001] This utility model relates to the field of edge trimmers, and in particular to an edge trimmer for the bottom edge of a ski. Background Technology

[0002] Edge trimming is a crucial step in ski maintenance, directly impacting handling, stability, and speed. With the increasing popularity of skiing and advancements in technique, more skiers are focusing on precise edge trimming. Most existing ski trimmers are manual, requiring adjustment of the tool's angle to ensure accuracy. However, these tools often suffer from instability, inconsistent trimming angles, and inconvenient adjustments. Traditional trimmers may be made of insufficiently durable materials or poorly designed, leading to inaccurate angle adjustments and affecting trimming effectiveness. Furthermore, some trimmers are prone to jamming or rough adjustment, causing difficulties for the user. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background section.

[0004] This utility model adopts the following technical solution: a ski edge trimmer, comprising a housing, an angle plate, a support foot, a hand-tightening screw, a support column, a compression spring, and a screw body. The housing has a file mounting groove inside, an angle viewing window and a toggle groove on its upper surface, a limit groove on its lower surface, and a screw column fixedly installed inside the limit groove. An angle adjustment rod is fixedly installed on the surface of the angle plate, and an angle mark is provided on its surface. A groove is formed on the bottom surface of the angle plate, and a sleeve is fixedly installed in the middle of the angle plate. A rib is fixedly installed on the surface of the support foot, and a support rib is fixedly installed on the bottom surface of the support foot. A round hole is formed in the middle of the support foot.

[0005] Preferably, the housing is made of die-cast aluminum alloy. Here, the die-cast aluminum alloy housing improves the durability and rigidity of the blade trimmer, effectively preventing deformation caused by external force or long-term use, thereby ensuring the accuracy and stability of the blade trimming angle and avoiding angle deviation caused by housing deformation.

[0006] Preferably, the support foot forms a stable support with the corresponding groove of the angle plate through four evenly distributed ribs. This ensures a precise fit between the support foot and the angle plate, thereby avoiding wobbling or instability of the angle plate during adjustment, preventing deformation under force that could lead to deviation in the sharpening angle, and making the operation of the sharpening tool more accurate.

[0007] Preferably, the support foot, the angle plate, and the housing form a bottom-up support fit. The angle plate is sleeved onto the screw post of the housing via a sleeve, and the support foot is sleeved onto the outside of the sleeve of the angle plate via a cylinder. Furthermore, the support foot is inserted into the limiting groove of the housing via a support rib. This design allows the angle plate to rotate coaxially around the screw post without jamming or axial movement, resulting in smoother angle adjustment and avoiding jamming or unnecessary friction.

[0008] Preferably, the compression spring passes through the circular hole and is fitted onto the surface of the sleeve, and the screw body passes through the circular hole and is threadedly connected to the screw post. Here, with the cooperation of the compression spring, the support foot can fit tightly against the angle plate during adjustment or sharpening, providing continuous support force, ensuring the stability of the sharpening tool, and avoiding angle deviation caused by vibration or pressure changes during use.

[0009] Preferably, the angle markings correspond to the positions of the angle viewing windows, the angle adjustment lever rotates inside the actuation groove, and the grooves are divided into three groups according to their depth, with each group corresponding to one of the three angle markings. Here, by actuating the angle adjustment lever, three different edge-trimming angles can be easily adjusted, meeting the needs of different skiers and improving the flexibility and operability of the edge-trimming process.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] In this invention, the housing is made of die-cast aluminum alloy to prevent deviation of the trimming angle due to deformation of the body, resulting in a more accurate trimming angle. The trimming angle is adjusted by rotating and toggling the angle adjustment lever. Three click-type toggles correspond to three trimming angles. The three angle indicators and the angle adjustment lever are all set on the circular angle plate. When the angle adjustment lever is toggled, the corresponding trimming angle is displayed in the angle window simultaneously. The support foot forms a stable fit with the corresponding groove of the angle plate through four evenly distributed ribs, preventing deformation under force that would cause deviation of the trimming angle. The support foot, angle plate, and housing form a bottom-up support fit to prevent deformation of the parts caused by pressing down force during trimming, which would lead to deviation of the trimming angle.

It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1

[0022] Please see Figure 1-5This utility model provides a technical solution: a ski edge trimmer, including a housing 1, an angle plate 2, a support foot 3, a hand-tightening screw 4, a support column 5, a compression spring 6, and a screw body 7. The housing 1 is made of die-cast aluminum alloy. The die-cast aluminum alloy housing 1 improves the durability and rigidity of the trimmer, effectively preventing deformation caused by external force or long-term use, thereby ensuring the accuracy and stability of the trimming angle and avoiding angle deviation caused by deformation of the housing 1. The housing 1 has a file mounting groove 101 inside, an angle viewing window 102 and a toggle groove 103 on the upper surface of the housing 1, and a limiting groove 105 on the lower surface of the housing 1. A screw post 104 is fixedly installed on the part of the angle disc 2. An angle adjustment rod 201 is fixedly installed on the surface of the angle disc 2. Angle markings 202 are provided on the surface of the angle disc 2. A groove 203 is opened on the bottom surface of the angle disc 2. The angle markings 202 correspond to the positions of the angle viewing window 102. The angle adjustment rod 201 rotates inside the groove 103. The groove 203 is divided into three groups according to different depths. The three groups of grooves 203 correspond to three groups of angle markings 202 respectively. When the angle adjustment rod 201 is moved, it can be easily adjusted to three different edge-trimming angles to meet the needs of different skiers and improve the flexibility and operability of the edge-trimming process. A sleeve 204 is fixedly installed in the middle of the angle disc 2. The support foot 3 has a raised rib 303 fixedly installed on its surface, and a support rib 301 fixedly installed on its bottom surface. A circular hole 302 is provided in the middle of the support foot 3. The support foot 3 forms a stable support with the corresponding groove 203 of the angle plate 2 through four evenly distributed raised ribs 303, ensuring precise fit between the support foot 3 and the angle plate 2. This prevents the angle plate 2 from shaking or becoming unstable during adjustment, and prevents deformation due to stress, which could lead to deviation in the sharpening angle. This makes the sharpening tool operation more precise. The support foot 3, angle plate 2, and housing 1 form a bottom-up support fit. The angle plate 2 is fitted onto the screw post 104 of the housing 1 through a sleeve 204, and the support foot 3 is fitted onto the... The angle disc 2 is located on the outside of the sleeve 204, and the support foot 3 is inserted into the limiting groove 105 of the housing 1 through the support rib 301. This allows the angle disc 2 to rotate coaxially around the screw post 104 without jamming or axial movement, making angle adjustment smoother and avoiding jamming or unnecessary friction. The compression spring 6 passes through the round hole 302 and is sleeved on the surface of the sleeve 204. The screw body 7 passes through the round hole 302 and is threadedly connected to the screw post 104. With the cooperation of the compression spring 6, the support foot 3 can fit tightly against the angle disc 2 during adjustment or sharpening, providing continuous support force and ensuring the stability of the sharpening tool, avoiding angle deviation caused by vibration or pressure changes during use.

[0023] Example 2

[0024] Please refer to 1-5. The housing 1 is made of die-cast aluminum alloy to better prevent deviation of the sharpening angle due to deformation of the housing 1. In addition, one end of the housing 1 is provided with a file mounting groove 101 and a hand-tightening screw 4 for mounting and fixing the file. The other end of the housing 1 is equipped with an angle plate 2, a support foot 3, a spring, and a screw body 7. The upper surface of the housing 1 is provided with an angle viewing window 102 and an angle adjustment rod 201 actuation groove 103. The upper surface of the angle plate 2 is provided with three angle indicators 202 and an angle adjustment rod 201. When the angle adjustment rod 201 is actuated, the corresponding sharpening angle is simultaneously displayed in the angle viewing window 102. The lower surface of the angle plate 2 is provided with three sets of grooves 203 of different depths, each set containing four evenly distributed grooves 203 of the same depth. The upper surface of the support foot 3 is provided with four evenly distributed ribs 303 of the same height. The shape and size of the ribs 303 match the grooves 203 on the lower surface of the angle plate 2. The lower surface of the support foot 3 is provided with support... The support rib 301 has its lower end face directly contacting the bottom surface of the ski for support. The housing 1 has a screw post 104 at the center of the angle adjustment rod 2, and a screw body 7 is locked on the top of the screw post 104. The center of the angle adjustment rod 2 has a sleeve 204 structure that wraps around the screw post 104. Through the gap between the sleeve 204, the screw post 104, and the screw body 7, the angle adjustment rod 201 can be turned so that the angle adjustment rod 201 can rotate coaxially around the screw post 104 without jamming or axial movement. The support foot 3 has a round hole 302 at its center and fits on the outer cylindrical surface of the sleeve 204 of the angle adjustment rod 2. A compression spring 6 is set between the screw body 7 and the support foot 3 so that the support foot 3 can fit tightly against the angle adjustment rod 2 when adjusting the angle or sharpening the edge. The housing 1 has corresponding limiting grooves 105 at the support ribs 301 on both sides of the support foot 3 so that the support foot 3 can move axially relative to the angle adjustment rod 2 along the center without axial rotation.

[0025] When the angle adjustment lever 201 is moved, the angle plate 2 rotates in three positions. At each position, the rib 303 on the upper surface of the support foot 3 matches the three sets of grooves 203 of different depths on the lower surface of the angle plate 2, thus forming three kinds of fitting gaps between the support foot 3 and the angle plate 2. Since the angle plate 2 can only rotate and cannot move axially, and the support foot 3 can only move axially and cannot rotate, the three different fitting gaps will result in three different relative heights of the support foot 3.

[0026] Before sharpening, adjust the sharpening angle. When sharpening, the two support columns 5 on the sharpening tool are close to the edge of the ski steel strip. Under the three different relative heights of the support feet 3, the file of the sharpening tool will rotate around the line of contact between the edge of the steel strip and the file surface, so that the file can grind the corresponding bottom edge angle on the surface of the steel strip.

[0027] Working principle: When in use, before sharpening, set the sharpening angle of the bottom edge sharpener to 0.5°. At this time, the four grooves 203 with the maximum depth on the lower surface of the angle plate 2 match the four ribs 303 of the same height on the upper surface of the support foot 3. The gap between the angle plate 2 and the support foot 3 is the minimum. The position of the support foot 3 moves down, and the relative height of the support ribs 301 on both sides of the support foot 3 is the minimum. When sharpening, the two support columns 5 on the sharpener are close to the edge of the ski steel strip. One side of the sharpener is supported by the two support ribs 301, and the other side is supported by the line of contact between the edge of the steel strip and the file surface. This makes the file surface and the bottom edge surface of the steel strip form a 0.5° angle, thereby sharpening the corresponding bottom edge angle.

[0028] When the sharpening angle of the bottom edge sharpener is set to 1.0°, the four medium-depth grooves 203 on the lower surface of the angle plate 2 match the four convex ribs 303 of the same height on the upper surface of the support foot 3. The gap between the angle plate 2 and the support foot 3 is medium. The position of the support foot 3 is lowered, and the relative height of the support ribs 301 on both sides of the support foot 3 is medium. When sharpening, the two support columns 5 on the sharpener are close to the edge of the ski steel strip. One side of the sharpener is supported by the support ribs 301 on both sides, and the other side is supported by the line of contact between the edge of the steel strip and the file surface, so that the file surface and the bottom edge surface of the steel strip form a 1.0° angle, thereby sharpening the corresponding bottom edge angle.

[0029] When the sharpening angle of the bottom edge sharpener is set to 1.5°, the four minimum depth grooves 203 on the lower surface of the angle plate 2 match the four ribs 303 of the same height on the upper surface of the support foot 3. The clearance between the angle plate 2 and the support foot 3 is at its maximum. The position of the support foot 3 is lowered, and the relative height of the support ribs 301 on both sides of the support foot 3 is at its maximum. When sharpening, the two support columns 5 on the sharpener are close to the edge of the ski steel strip. One side of the sharpener is supported by the two support ribs 301, and the other side is supported by the line of contact between the edge of the steel strip and the file surface. This makes the file surface and the bottom edge surface of the steel strip form a 1.5° angle, thereby sharpening the corresponding bottom edge angle.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
