Description

Technical Field

[0001] This utility model relates to the field of roller skate technology, and in particular to an invisible roller skate base bracket. Background Technology

[0002] In roller skating and everyday skating applications, roller skates play a crucial role as key equipment. Roller skates, also known as inline skates, have evolved and are now widely used in various fields such as leisure and entertainment and sports competitions.

[0003] From a structural design perspective, existing roller skates typically have their wheels fixedly mounted to the bottom of the skate body using specific mounting components such as wheel frames and spikes, with the wheels fully exposed on the outside of the skate. This design allows the wheels to directly contact the ground during skating, enabling efficient movement through wheel rolling. However, this design, with the wheels fixed on the outside, has certain limitations. In certain scenarios, such as walking on surfaces unsuitable for roller skating (e.g., stairs, uneven surfaces), the wheels cannot be retracted and hidden. The continuous contact between the wheels and the ground not only easily causes unnecessary wear on the wheels but may also cause inconvenience to the user due to the rolling characteristics of the wheels, and even pose a safety hazard of slipping and falling. Therefore, this utility model proposes an invisible roller skate base bracket to solve the problems existing in the prior art. Utility Model Content

[0004] To address the aforementioned issues, this utility model proposes an invisible roller skate base bracket, which consists of a main frame, a base frame, and a slide. The slide can move horizontally within the main frame. Utilizing the matching action of the inclined groove and the linkage rod, the base frame is driven to rise and fall. The base frame rises and falls within the main frame, thereby lowering and retracting the pulley assembly, achieving the effect of retracting and concealing the pulley assembly, suitable for various application scenarios.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: an invisible roller skate base bracket, including a main frame, a base frame and a slide frame. The base frame is located below the interior of the main frame, and a pulley assembly extending out of the main frame is provided on the base frame. The slide frame is elastically slidably located above the interior of the main frame. Both ends of the base frame are provided with linkage rods, and both ends of both sides of the main frame are provided with sliding grooves. The linkage rods movably pass through the sliding grooves.

[0006] Both ends of the bottom of the slide are provided with inclined grooves that are adapted to the linkage rod. One end of the slide and one end of the main frame are fixed and unlocked by a locking fastener.

[0007] A further improvement is that a guide rod is provided at one end of the upper part of the main frame, and guide grooves are provided at one end of both sides of the slide, with the guide rod and guide grooves being movably adapted to each other.

[0008] A further improvement is that a connecting rod is provided at the middle of the interior of the carriage, and a spring connects the connecting rod and the guide rod.

[0009] A further improvement is that the locking fastener includes a mounting base and a fastening rod. The mounting base is located at one end of the main frame, and the fastening rod is connected to the mounting base. One end of the top of the slide is provided with an adapter groove, and one end of the adapter groove is provided with a locking block and a guide wedge. One side of the locking block is a slope, and one end of the locking block is provided with a fastening groove that matches the fastening rod.

[0010] A further improvement is that a pressing post is provided at the end of the carriage away from the locking element, and the pressing post extends out of the main frame.
