Description

Technical Field

[0001] This utility model relates to the field of luggage accessories technology, specifically to a luggage caster brake device. Background Technology

[0002] With the increasing frequency of travel, luggage, as a commonly used storage and carrying tool, has received widespread attention for its convenience and safety. Casters, as an important component of luggage, enable flexible movement, but in some situations, it is necessary to lock the casters to prevent the luggage from sliding freely. Therefore, caster braking devices have emerged.

[0003] Currently, there are many types of brake devices for luggage casters on the market, but most suffer from problems such as complex structure, inconvenient operation, unstable brake locking, and unsmooth unlocking. Some existing brake devices achieve braking function through linkage mechanisms or simple cable structures, but linkage mechanisms often occupy a lot of space, reducing the internal storage space of the luggage, and are also difficult to assemble; while simple cable structures are prone to loosening and jamming after long-term use, affecting the braking effect.

[0004] Furthermore, some braking devices have poorly designed locking and unlocking mechanisms, making them prone to accidental unlocking after locking or requiring significant force to unlock, causing inconvenience to users. Additionally, the precision of the components in existing braking devices is insufficient, leading to wear and loosening of parts and connections after frequent braking and unlocking operations, thus reducing the lifespan of the braking device. Therefore, there is an urgent need for a simple, easy-to-operate, stable-locking, and long-lasting luggage caster braking device to solve these problems. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a brake device for luggage casters, which simplifies the product structure, makes operation convenient, and makes the brake locking more stable.

[0006] To solve the above-mentioned technical problems, this utility model provides a brake device for luggage casters, including a housing. Inside the housing are a rotatable toggle switch, an unlock button, a sliding buckle, and a steel wire assembly. The toggle switch is connected to the sliding buckle via a spring wire. The lower part of the sliding buckle is connected to one end of the steel wire assembly, and the other end of the steel wire assembly is connected to a braking mechanism on the luggage caster. The sliding buckle is adapted to the unlock button so that pressing the unlock button unlocks the sliding buckle. A return spring is provided between the sliding buckle and the unlock button. Its technical effects are as follows: Structural aspects: The overall structure is simple and compact, with all components integrated into the shell, occupying little space. It does not require complex linkage mechanisms, effectively saving internal storage space in the bag, and the assembly process is simple, reducing the difficulty of production and assembly. Transmission aspect: The transmission path of the toggle switch is clear, with the spring wire connecting to the slide buckle and the slide buckle linking with the steel wire assembly. All components fit together tightly, the driving force is transmitted without redundancy, and the transmission is reliable, avoiding the loosening and jamming problems that are prone to occur in the existing simple pull-wire structure. Operation and locking: The brake can be triggered by tossing the switch and the unlock button can be pressed to unlock, making operation convenient; the reset spring ensures that each component can quickly reset after action, the brake lock state is stable, there is no risk of accidental unlocking, and the unlocking process is smooth, solving the problems of unstable locking and large operating force required for unlocking in existing devices.

[0007] The spring wire is U-shaped, with both ends connected to the toggle switch. A groove is provided in the middle of the sliding latch, and the middle part of the spring wire engages with this groove. The technical effects are as follows: Connection stability: The middle part of the U-shaped spring wire engages with the groove in the middle of the slide buckle, forming a precise and firm connection structure. This prevents the spring wire and the slide buckle from falling off, shifting, or sliding relative to each other during transmission, ensuring that the driving force of the toggle switch can be accurately transmitted to the slide buckle, further improving transmission reliability. Space adaptability: The U-shaped spring wire can flexibly adapt to the limited space inside the housing without the need for additional installation space, maintaining the overall compact structure of the device. At the same time, the design of connecting to the toggle switch at both ends facilitates the assembly and positioning of the spring wire, improving assembly efficiency.

[0008] The upper part of the sliding buckle is provided with a locking hook, and the unlocking button is provided with a positioning rod that corresponds to and engages with the locking hook. Its technical effects are as follows: Connection stability: The middle part of the U-shaped spring wire engages with the groove in the middle of the slide buckle, forming a precise and firm connection structure. This prevents the spring wire and the slide buckle from falling off, shifting, or sliding relative to each other during transmission, ensuring that the driving force of the toggle switch can be accurately transmitted to the slide buckle, further improving transmission reliability. Space adaptability: The U-shaped spring wire can flexibly adapt to the limited space inside the housing without the need for additional installation space, maintaining the overall compact structure of the device. At the same time, the design of connecting to the toggle switch at both ends facilitates the assembly and positioning of the spring wire, improving assembly efficiency.

[0009] The unlock button is equipped with a pressing spring. The pressing spring provides a stable reset force for the unlock button, ensuring that the unlock button can quickly and accurately return to its initial position after the unlocking operation is completed. This prevents the unlock button from becoming misaligned and causing it to fail to engage with the sliding latch during the next locking operation, thus ensuring the reliability of the device for repeated use.

[0010] One end of the steel wire assembly is connected to a steel wire support member. A rectangular cavity is provided at the lower part of the sliding buckle, and the steel wire support member is disposed within this rectangular cavity. A steel wire support member spring, also located within the rectangular cavity, is fitted over the steel wire support member. Its technical effects are as follows: Connection stability: The matching design of the steel wire drag and the lower rectangular cavity of the sliding buckle enables precise positioning and connection between the steel wire assembly and the sliding buckle, limits the range of motion of the steel wire drag, and prevents the steel wire from shaking, shifting or falling off during the reciprocating transmission of braking and unlocking, thus ensuring the accuracy of force transmission. Buffering and wear resistance: The steel wire drag spring can absorb the impact force generated during braking and unlocking, reduce the rigid contact wear between the steel wire assembly and the slip buckle, and buffer the instantaneous force during the transmission process, reduce the fatigue wear of each component, and significantly extend the overall service life of the device. Reset assistance: The elastic restoring force of the steel wire drag spring can assist the slip buckle to quickly reset after unlocking, further improving the smoothness of unlocking and brake reset, while ensuring the stability of the tension of the steel wire assembly during braking, avoiding the impact of tension fluctuations on the braking effect, and ensuring the consistency of brake locking.

[0011] The beneficial effects of this utility model are: this luggage caster brake device drives the spring wire to pull the sliding buckle by toggling the switch, and the sliding buckle controls the brake mechanism through the steel wire to achieve braking. At the same time, the brake is locked by the cooperation of the unlock button and the sliding buckle. The unlock button can be pressed to unlock. The overall structure is simple and compact, occupies little space, and is easy to assemble. The components are closely matched, the transmission is reliable, the brake locking is stable, the unlocking is smooth, and the operation is convenient. Attached Figure Description
