Description

Technical Field

[0001] This utility model relates to the field of roller skate technology, specifically to a roller skate with adjustable rubber wheels. Background Technology

[0002] Roller skates are a type of skating device with four wheels arranged side by side. The main components include the skate shell, wheels, bearings, and frame. They are usually equipped with a brake for the right foot. They are suitable for various occasions such as recreational skating, speed skating, and freestyle skating. Choosing the right size and purpose of roller skates, regular maintenance, and wearing protective gear are key to safe skating. Inline skating can improve physical fitness and bring fun, making it suitable for people of all ages.

[0003] Inline skates, with their sleek four-wheel design and ergonomic shell, balance speed and comfort. However, they still have certain drawbacks: traditional inline skates contain bearings to improve the rolling speed and smoothness of the rubber wheels, but the friction of the axle cannot be adjusted. As a result, the rubber wheels rotate at extremely high speeds, which makes learning difficult and increases the risk of falls for beginners. Therefore, there is an urgent need to develop inline skates with adjustable rubber wheel flexibility to overcome the shortcomings in current applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a roller skate with adjustable rubber wheel flexibility to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a roller skate with adjustable rubber wheel flexibility, comprising a base plate, a main shaft and a rubber wheel, the main shaft being inserted through the middle of the rubber wheel and fixedly connected to the rubber wheel, the main shaft being rotatably mounted on the bottom of the base plate, a wheel locking mechanism being fixedly provided on the bottom edge of the base plate, and a shoe body being fixedly provided on the top of the base plate;

[0006] The locking wheel mechanism includes a housing, a brake disc, and a brake plate. The housing is fixed to the bottom edge of the base plate, the brake plate is sleeved on one end of the main shaft, and multiple horizontal guide posts are fixed to the inner wall of the housing. The brake plate can be slidably mounted on the guide posts.

[0007] Preferably, a knob is rotatably mounted on the outer side of the housing, and a stud is fixed on the inner wall of the knob. The stud passes through the middle of the brake disc and is connected to the brake disc by threads. Specifically, the knob and the stud are used to drive the brake disc to move axially along the guide post. The smaller the distance between the brake disc and the brake wheel, the greater the friction, thereby controlling the rotational resistance of the spindle and the rubber wheel.

[0008] Preferably, a threaded hole is provided in the middle of the brake disc, and the stud is adapted to the threaded hole. Specifically, the threaded hole can cooperate with the stud to achieve position adjustment.

[0009] Preferably, multiple positioning rings are fixed at the edge of the brake disc. The positioning rings are slidably connected to the guide posts and correspond one-to-one. Specifically, the positioning rings and guide posts cooperate with each other to restrict the movement path of the brake disc.

[0010] Preferably, a brake pad is installed on one side of the brake disc, and a groove is formed on one side of the brake disc. The brake pad is adapted to the groove of the brake disc. Specifically, the rotational flexibility of the spindle and the rubber wheel is controlled by the friction between the brake pad and the brake disc.

[0011] Compared with the prior art, this utility model provides a roller skate with adjustable rubber wheel flexibility, which has the following beneficial effects:

[0012] One end of the spindle is equipped with a locking wheel mechanism for controlling the rotational friction of the spindle and the rubber wheel. It controls the speed of the spindle and the rubber wheel by relying on the friction generated between the brake disc and the brake disc. This enables precise control of the spindle rotation smoothness, and the control process is smoother, allowing the rotational flexibility of the spindle and the rubber wheel to adapt to the actual usage needs of different users.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] Example:

[0024] Please see Figures 1-6 This utility model provides a technical solution: a roller skate with adjustable rubber wheel flexibility, including a base plate 10, a main shaft 20 and a rubber wheel 30. The main shaft 20 is inserted through the middle of the rubber wheel 30 and is fixedly connected to the rubber wheel 30. The main shaft 20 is rotatably mounted on the bottom of the base plate 10. A wheel locking mechanism 40 is fixedly provided on the bottom edge of the base plate 10, and a shoe body 50 is fixedly provided on the top of the base plate 10.

[0025] The locking wheel mechanism 40 includes a housing 401, a brake disc 403 and a brake disc 404. The housing 401 is fixed to the bottom edge of the base plate 10. The brake disc 404 is sleeved on one end of the main shaft 20. Multiple horizontal guide posts 405 are fixed on the inner wall of the housing 401. The brake disc 403 can be slidably mounted on the guide posts 405.

[0026] Preferably, a knob 402 is rotatably mounted on the outer side of the housing 401. A stud 406 is fixed on the inner wall of the knob 402. The stud 406 passes through the middle of the brake disc 403 and is threadedly connected to the brake disc 403. Specifically, the knob 402, in conjunction with the stud 406, drives the brake disc 403 to move axially along the guide post 405. The smaller the distance between the brake disc 403 and the brake disc 404, the greater the friction, thereby controlling the rotational resistance of the main shaft 20 and the rubber wheel 30.

[0027] Preferably, a threaded hole 4033 is provided in the middle position of the brake disc 403, and the stud 406 is adapted to the threaded hole 4033. Specifically, the threaded hole 4033 can cooperate with the stud 406 to achieve position adjustment.

[0028] Preferably, a plurality of positioning rings 4031 are fixedly provided at the edge of the brake disc 403. The positioning rings 4031 are slidably connected to the guide post 405 and correspond one to one. Specifically, the positioning rings 4031 and the guide post 405 cooperate with each other to restrict the movement path of the brake disc 403.

[0029] Preferably, a brake pad 4032 is installed on one side of the brake disc 403, and a groove is provided on one side of the brake disc 404. The brake pad 4032 is adapted to the groove of the brake disc 404. Specifically, the rotational flexibility of the main shaft 20 and the rubber wheel 30 is controlled by the mutual friction between the brake pad 4032 and the brake disc 404.

[0030] Working principle: When using this type of roller skate, the user can manually rotate the knob 402 to adjust the braking force of the locking wheel mechanism 40, thereby controlling the rotational resistance and smoothness of the main shaft 20 and the rubber wheel 30, making the roller skate more adaptable to the user's control. When the knob 402 is rotated clockwise, it can drive the stud 406 to rotate clockwise, thereby driving the brake disc 403 to move along the guide post 405 axially towards the brake disc 404, thereby increasing the friction and increasing the rotational resistance of the main shaft 20. Rotating the knob 402 counterclockwise has the opposite effect.

[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
