Description

Technical Field

[0001] This utility model relates to the field of roller skating equipment technology, and more specifically, to a low center of gravity urban roller skating cutter holder. Background Technology

[0002] The roller skate frame is a bracket that connects the roller skate and the wheels. It not only fixes the position of the wheels but also serves as the load-bearing structure for the roller skate. Currently, commercially available urban roller skate frames suffer from the following technical challenges: 1. Most products pursue larger wheel sizes to increase speed, but ignore the problem of insufficient stability caused by an excessively high center of gravity. They are prone to imbalance when gliding at high speeds and have sluggish turning response.

[0003] 2. Traditional tool holders are mostly symmetrical structures, resulting in dispersed power transmission when pushing off the ground. Furthermore, the standard 4×80mm tool holder has weak high-speed stability, while the 4×90mm tool holder has poor flexibility and acceleration, making it difficult to balance "high-speed stability" and "flexible control".

[0004] 3. The compatibility between the skate frame and the skates is limited. Different brands and sizes of skates often have difficulty fitting due to their fixed installation position and lack of adjustment space. Custom-made skate frames are required, which increases the user's cost.

[0005] 4. Some blade holders use a multi-part splicing structure, which is not strong and durable enough. When used on complex urban road conditions (such as gravel roads and the edges of steps), the parts are prone to loosening and deformation, affecting gliding safety and service life. Utility Model Content

[0006] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a city wheel chuck knife holder that has a low center of gravity, balances stability and flexibility, has strong compatibility and a robust structure.

[0007] To achieve the above objectives, this utility model provides a low-center-of-gravity urban roller skate tool holder, comprising a tool holder body integrally formed from metal material. The tool holder body has tool holder side plates, a front mounting platform, and a rear mounting platform. Two tool holder side plates are provided and symmetrically arranged. The lower ends of both tool holder side plates are provided with a first wheel axle mounting position, a second wheel axle mounting position, a third wheel axle mounting position, and a fourth wheel axle mounting position arranged sequentially from front to back. The distance between the first wheel axle mounting position and the second wheel axle mounting position is greater than the distance between the second wheel axle mounting position and the third wheel axle mounting position. The distance between the third and fourth wheel axle mounting positions; the two sides of the front mounting platform are respectively connected to the top front end of the two tool holder side plates; the front mounting platform is located between the first and second wheel axle mounting positions; the front mounting platform is provided with a first sliding adjustment hole extending forward and backward; the two sides of the rear mounting platform are respectively connected to the top rear end of the two tool holder side plates; the rear mounting platform is located between the third and fourth wheel axle mounting positions; the height of the rear mounting platform is higher than the height of the front mounting platform; the rear mounting platform is provided with a second sliding adjustment hole extending forward and backward.

[0008] Preferably, both tool holder side plates include a lower end, a middle part, and an upper end connected sequentially from bottom to top. The lower end of the side plate is flat, and the middle part of the side plate is convex arc-shaped. The first wheel axle mounting position, the second wheel axle mounting position, the third wheel axle mounting position, and the fourth wheel axle mounting position are all located at the lower end of the side plate.

[0009] Preferably, the side plate has several through holes extending laterally through the middle part.

[0010] Preferably, the vertical distance between the top surface of the rear mounting platform and the lowest bottom surface of the tool holder side plate is 53.5 mm.

[0011] Preferably, the distance between the center of the first wheel axle mounting position and the center of the fourth wheel axle mounting position is 280mm.

[0012] Preferably, a connecting beam is provided between the top and / or bottom of the two tool holder side plates.

[0013] Preferably, axles are provided between the two first wheel axle mounting positions, the two second wheel axle mounting positions, the two third wheel axle mounting positions, and the two fourth wheel axle mounting positions on the two tool holder side plates.

[0014] Preferably, the axle is configured as a single-sided wheel screw.

[0015] Preferably, the device also includes two height-increasing pads, which are respectively mounted on the front mounting platform and the rear mounting platform. Each of the two height-increasing pads is provided with a third sliding adjustment hole extending forward and backward. The position of the third sliding adjustment hole of one height-increasing pad corresponds to the position of the first sliding adjustment hole, and the position of the third sliding adjustment hole of the other height-increasing pad corresponds to the position of the second sliding adjustment hole.

[0016] Preferably, the bottom of the height-increasing pad is provided with a positioning protrusion, and the top of the front mounting platform and the rear mounting platform are respectively provided with positioning grooves.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Low center of gravity structure design: The front mounting platform of the tool holder body is set between the first wheel axle mounting position and the second wheel axle mounting position. The geometry of the 4×80mm pulley block is optimized so that the center of gravity of the sliding block is lower than that of existing products on the market after the pulley block is installed, reducing vertical swaying and improving balance performance and ground force efficiency.

[0018] 2. Asymmetrical wheel layout: The four wheel axle mounting positions of the frame body are asymmetrically distributed. The distance between the second, third and fourth wheel axle mounting positions is reduced and they correspond to the area below the heel of the skate, shortening the lever arm during turning and improving the turning response speed. The distance between the first and second wheel axle mounting positions is increased, expanding the power range when pushing off the ground and enhancing the power output of each push-off, while ensuring stability throughout the skating process.

[0019] 3. Progressive flat bottom configuration: The main body of the tool holder adopts a flat bottom structure with a slight curve at the bottom (sublterockering). Combined with a unique wheel arrangement and a 280mm wheelbase, it improves high-speed gliding stability compared to the standard 243mm wheelbase 4×80mm tool holder, and offers better steering flexibility and acceleration response compared to the 4×90mm tool holder.

[0020] 4. Flexible Adaptable Components: The mounting components include a sliding adjustment hole type mounting structure and a height-increasing pad. The sliding adjustment hole is located on the top of the blade holder body and cooperates with the mounting holes on the bottom of the roller skate, allowing for fine adjustment of the blade holder's front and rear position to accommodate different users' standing habits. The height-increasing pad can be installed according to the thickness of the roller skate sole, making the blade holder compatible with various urban roller skates and roller skates with a standard 165mm hole spacing, improving universal compatibility.

[0021] 5. Integrated molding and material selection: The main body of the tool holder is made of a single piece of high-grade 6000 series aluminum alloy through extrusion molding and then precision CNC machining, with no splicing gaps; the wheel axle adopts a single-sided wheel axle screw, which simplifies the wheel disassembly and assembly process, while ensuring the connection strength between the wheel axle and the main body of the tool holder, and can withstand the impact of complex urban road conditions, avoiding deformation or damage.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0025] Please refer to Figure 1 Embodiment 1 of this utility model provides a low center of gravity urban roller skate tool holder, including a tool holder body 1 integrally formed of metal material. The components of this embodiment will be described in detail below with reference to the accompanying drawings.

[0026] The tool holder body 1 can be made from a single piece of 6000 series aluminum alloy through extrusion molding and then precision CNC machining. For example... Figures 1 to 4As shown, the tool holder body 1 may include a tool holder side plate 11, a front mounting platform 12 and a rear mounting platform 13. There are two tool holder side plates 11 arranged symmetrically to each other. Each tool holder side plate 11 may include a lower end 111, a middle part 112 and an upper end 113 connected sequentially from bottom to top. The lower end 111 of the side plate is flat, and the middle part 112 of the side plate is convex arc-shaped with a slight curvature.

[0027] like Figure 2 As shown, the lower ends 111 of the two tool holder side plates 11 are provided with a first wheel axle mounting position 14, a second wheel axle mounting position 15, a third wheel axle mounting position 16, and a fourth wheel axle mounting position 17 arranged sequentially from front to back. The distance between the first wheel axle mounting position 14 and the second wheel axle mounting position 15 is greater than the distance between the second wheel axle mounting position 15 and the third wheel axle mounting position 16, and the distance between the third wheel axle mounting position 16 and the fourth wheel axle mounting position 17. The four wheel axle mounting positions are asymmetrically distributed.

[0028] Preferably, the distance between the center of the first wheel axle mounting position 14 and the center of the fourth wheel axle mounting position 17 can be set to 280mm. The projections of the second wheel axle mounting position 15, the third wheel axle mounting position 16, and the fourth wheel axle mounting position 17 correspond to the area below the heel of the roller skate.

[0029] like Figure 2 As shown, several through holes 114 can be horizontally penetrated on the middle part 112 of the side plate.

[0030] like Figure 1 As shown, the front mounting platform 12 is connected to the top front end of the two tool holder side plates 11 on both sides. The front mounting platform 12 is located between the first wheel shaft mounting position 14 and the second wheel shaft mounting position 15. The front mounting platform 12 is provided with a first sliding adjustment hole 121 extending back and forth, i.e., a waist-shaped hole.

[0031] like Figure 1 and Figure 2 As shown, the two sides of the rear mounting platform 13 are connected to the top of the rear end of the two tool holder side plates 11 respectively. The rear mounting platform 13 is located between the third wheel axle mounting position 16 and the fourth wheel axle mounting position 17. The height of the rear mounting platform 13 is higher than the height of the front mounting platform 12. The rear mounting platform 13 is provided with a second sliding adjustment hole 131 extending back and forth, i.e., a waist-shaped hole.

[0032] In this embodiment, the vertical distance between the top surface of the rear mounting platform 13 and the lowest bottom surface of the tool holder side plate 11 is preferably 53.5 mm.

[0033] To enhance the structural strength of the tool holder body 1, a connecting beam 18 may be provided between the top and bottom of the two tool holder side plates 11.

[0034] like Figure 5 As shown, wheel axles 2 are respectively provided between the two first wheel axle mounting positions 14, the two second wheel axle mounting positions 15, the two third wheel axle mounting positions 16, and the two fourth wheel axle mounting positions 17 of the two tool holder side plates 11.

[0035] Preferably, the wheel axle 2 can be set as a common single-sided wheel screw, which can be made of steel and has threads machined on one end.

[0036] The roller skate cutter holder of this embodiment is adapted to a 4×80mm pulley block, and the sliding adjustment hole allows the cutter holder to be adapted to roller skates with a standard 165mm hole spacing. Example

[0037] Please refer to Figure 6 Embodiment 2 of this utility model provides a low center of gravity urban roller slide tool holder, which also includes a tool holder body 1 integrally formed of metal material. Based on the above embodiment 1, the roller slide tool holder of this embodiment 2 also includes two heightening pads 3. The heightening pads 3 can be made of aluminum alloy material, and the thickness of the heightening pads 3 can be arbitrarily set.

[0038] like Figure 6 As shown, two height-increasing pads 3 are respectively installed on the front mounting platform 12 and the rear mounting platform 13. Each of the two height-increasing pads 3 is provided with a third sliding adjustment hole 31 extending forward and backward, i.e. a waist-shaped hole. The position of the third sliding adjustment hole 31 of one height-increasing pad 3 corresponds to the position of the first sliding adjustment hole 121, and the position of the third sliding adjustment hole 31 of the other height-increasing pad 3 corresponds to the position of the second sliding adjustment hole 131.

[0039] like Figure 7 As shown, to facilitate the positioning and installation of the height-increasing pad 3, a positioning protrusion 32 can be provided at the bottom of the height-increasing pad 3. Correspondingly, positioning grooves 19 are provided at the top of the front mounting platform 12 and the rear mounting platform 13, respectively. The positioning protrusion 32 of the height-increasing pad 3 can be inserted into the corresponding positioning groove 19.

[0040] The height-increasing pad 3 can be used with the sliding adjustment hole to adjust the height of the skate frame and roller skates.

[0041] Assembly process: Screw the wheel axle (i.e., wheel screw) into the wheel axle mounting position of the blade holder body until it is secure; if the sole of the roller skate is thin, place the height-increasing pad between the blade holder body and the roller skate, and adjust the front and back position of the blade holder until it fits the user by passing the bolt through the sliding adjustment hole, the height-increasing pad and the roller skate mounting hole. Tighten the bolt to complete the assembly.

[0042] Application scenario verification of this utility model of the roller slide tool holder Tests were conducted on urban roads (including asphalt roads, sidewalks, and slightly damaged road surfaces). The test conditions and results are as follows: 1. Stability Test: A 75kg user wearing roller skates with a compatible frame skated at 15km / h in a straight line and could skate for more than 15 seconds with both hands off the handlebars (without balance aids). Compared to existing frames (which can only last 8-10 seconds), the stability is significantly improved.

[0043] 2. Handling test: When making a 90° turn at a speed of 10km / h, the turning radius can be controlled within 1.5m, and there is no obvious body roll when turning. Compared with the 4×90mm tool holder (turning radius 2-2.5m), it has better flexibility.

[0044] 3. Compatibility test: When installed on any adult hard-shell skates and other brands of hard-shell skates with a 165mm hole spacing, the skates can be adjusted to a suitable stance via the sliding adjustment holes without any installation interference issues.

[0045] 4. Durability test: After 100 hours of continuous sliding on urban roads (including 5 daily contact with the edge of steps), the main body of the tool holder showed no deformation, the wheel axle did not loosen, and the mounting bolts of the sliding adjustment hole showed no stripping.

[0046] The roller slide tool holder of this utility model has the following advantages: 1. Performance Improvement: The low center of gravity design shortens the distance between the human body and the ground during gliding, improving balance performance by more than 30% (compared to existing blades of the same size), and power transmission efficiency by 20%, making the push-off force more direct; the combination of asymmetrical wheel layout and progressive flat bottom configuration solves the contradiction between "instability at high speed" and "insufficient agility", making it suitable for the changing scenarios of "uniform speed gliding - fast turning - instant acceleration" in the city.

[0047] 2. Enhanced compatibility: The sliding adjustment hole mounting structure, in conjunction with the height-increasing pad, can be adapted to 165mm hole-pitch roller skates of different brands and sizes, eliminating the need for additional customization and reducing the cost of replacing the skate frame for users.

[0048] 3. Optimized durability: The one-piece molded 6000 series aluminum alloy body is CNC machined, and its tensile strength and deformation resistance are superior to the spliced ​​tool holder. It can withstand long-term use by users weighing less than 100kg on urban roads (including light bumps and contact with the edge of steps), and its service life is extended by more than 50%.

[0049] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
