Description

Technical Field

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

[0002] Most travel bags are equipped with casters so that people can easily drag the bags.

[0003] Publication number CN221437621U discloses a luggage caster that uses a self-lubricating component to transform the sliding friction between the positioning ring and the caster bracket during rotation into rolling friction, reducing the coefficient of friction and thus decreasing the resistance encountered by the luggage caster during rotation, improving flexibility. For two-wheeled luggage, when temporarily placed on the ground, the luggage body will only touch the ground once, which can lead to damage over time and affect usability. For four-wheeled luggage, with all four wheels on the ground, the user's arms are bent, and prolonged movement can cause discomfort. Dragging causes the caster furthest from the handle to frequently contact the ground, resulting in a higher failure rate compared to the inner casters. Therefore, we propose a luggage caster device. Utility Model Content

[0004] In view of the problems in the prior art, this utility model provides a luggage caster device.

[0005] The technical solution adopted by this utility model to solve its technical problem is a luggage caster device, including a storage shell. A pivot chamber is integrally constructed on one side of the storage shell. A locking gear is rotatably connected inside the pivot chamber through a connecting shaft. A linkage rod is interference-fitted to the side wall of the locking gear. A coupling is installed at the end of the linkage rod away from the locking gear, and the linkage rod is connected to the mounting handle through the coupling. The mounting handle is integrally constructed on both sides of the connecting bracket. The side of the connecting bracket away from the pivot chamber is rotatably connected to the interior of the driven mounting groove through the connection structure of the mounting handle and the connecting bracket.

[0006] The surface of the storage housing is rotatably connected to a knob, and the bottom end of the knob is integrally constructed with a threaded sleeve. The bottom end of the threaded sleeve is screwed to a threaded connecting rod, which is fixedly connected to the top center of the limiting plate. The two sides of the limiting plate slide inside the limiting groove, and the limiting groove is opened on the inner walls of both sides of the storage housing.

[0007] By adopting the above technical solution, in the freely adjustable state, the connecting bracket can rotate inside the shaft compartment and the driven mounting slot along with the connecting structure of the mounting handle and the coupling. This allows the casters to be stored in the storage housing or unfolded. After switching to the correct state, the spring self-resets, causing the locking strip to engage with the locking teeth of the locking gear. This limits the rotation of the locking gear, linkage rod, coupling, mounting handle, connecting bracket, and driven mounting slot, thus achieving the storage of the casters. This ensures that the bottom of the entire housing contacts the ground, rather than the outer corner, which relatively improves the service life. Furthermore, when placing the housing, it reduces the space occupied by the casters, making it easier to store the housing and preventing damage to the casters from external forces.

[0008] When storing the casters, rotating the knob drives the threaded sleeve to rotate, causing the threaded connecting rod to move vertically under the restriction of the limiting plate and the limiting groove, thereby locking it at the opening of the storage housing. This prevents the casters from getting stuck in the gear and locking strip and rotating out under special circumstances.

[0009] Specifically, a lever plate is rotatably connected to one side of the top of the rotating shaft compartment. One end of the lever plate that passes through the rotating shaft compartment has an integrally constructed locking strip, and the locking strip and the locking gear form a ratchet structure.

[0010] By adopting the above technical solution, in the unfolded state, the constantly locked clip is locked in the locking gear to form a self-locking state. When it is necessary to adjust the caster, the lever can be moved to adjust it.

[0011] Specifically, the bottom end of the connecting bracket is equipped with a swivel caster that can turn freely.

[0012] By adopting the above technical solution, after removing the casters, the box can be moved by using two casters on one side.

[0013] Specifically, a bottom pad is fixedly connected to the bottom end of the storage housing.

[0014] By adopting the above technical solution, the bottom pad contacts the ground to support the entire box.

[0015] Specifically, the bottom end of the bottom pad is flush with the bottom of the box.

[0016] By adopting the above technical solution, the casters are stored away, so that the bottom of the box is in contact with the ground as a whole instead of just one side. This increases the contact area, spreads the pressure exerted on the box by gravity, and relatively improves its service life.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The connecting bracket of this application can rotate inside the shaft compartment and driven mounting slot along with the connecting structure of the mounting handle and coupling. This allows the casters to be stored in the storage housing or unfolded. After switching to the correct state, the spring self-resets, causing the locking strip to engage with the locking teeth of the locking gear. This limits the rotation of the locking gear, linkage rod, coupling, mounting handle, connecting bracket, and driven mounting slot, thus achieving the storage of the casters. This ensures that the bottom of the entire housing contacts the ground, rather than the outer corner, which relatively improves the service life. Furthermore, it reduces the space occupied by the casters when placing the housing, making it easier to store the housing and preventing damage to the casters from external forces.

[0019] When storing the casters, rotating the knob drives the threaded sleeve to rotate, causing the threaded connecting rod to move vertically under the restriction of the limiting plate and the limiting groove, thereby locking it at the opening of the storage housing. This prevents the casters from getting stuck in the gear and locking strip and rotating out under special circumstances. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please see Figure 1-3This utility model provides a technical solution: a luggage caster device, including a storage housing 1, a rotating shaft compartment 2 integrally constructed on one side of the storage housing 1, a locking gear 3 rotatably connected inside the rotating shaft compartment 2 via a linkage shaft, a linkage rod 4 interference-fitted to the side wall of the locking gear 3, a coupling 5 mounted on the end of the linkage rod 4 away from the locking gear 3, and the linkage rod 4 connected to the mounting handle 6 via the coupling 5, the mounting handle 6 integrally constructed on both sides of the connecting bracket 7, and the side of the connecting bracket 7 away from the rotating shaft compartment 2 rotatably connected to the interior of the driven mounting groove 9 through the connection structure of the mounting handle 6 and the connecting bracket 7;

[0027] A knob 11 is rotatably connected to the surface of the storage housing 1. A threaded sleeve 12 is integrally formed at the bottom end of the knob 11. A threaded connecting rod 13 is screwed to the bottom end of the threaded sleeve 12. The threaded connecting rod 13 is fixedly connected to the top center of the limiting plate 14. The two sides of the limiting plate 14 slide inside the limiting groove 15, and the limiting groove 15 is opened on the inner walls of both sides of the storage housing 1.

[0028] By adopting the above technical solution, in the freely adjustable state, the connecting bracket 7 can rotate inside the shaft chamber 2 and the driven mounting groove 9 along with the connecting structure of the mounting handle 6 and the coupling 5, so that the caster 8 can be stored in the storage housing 1 or unfolded. After switching to the correct state, the spring will automatically reset so that the locking strip 10 can be engaged in the locking teeth of the locking gear 3, thereby limiting the rotation structure of the locking gear 3, the linkage rod 4, the coupling 5, the mounting handle 6, the connecting bracket 7 and the driven mounting groove 9, realizing the storage of the caster, so that the bottom of the entire box is in contact with the ground, rather than the outer corner, which relatively improves the service life. Moreover, when placing it, it can reduce the space occupied by the caster, facilitate the storage of the box, and avoid damage to the caster from external forces.

[0029] When storing the caster, the threaded sleeve 12 is rotated by turning the knob 11, which causes the threaded connecting rod 13 to move vertically under the restriction of the limiting plate 14 and the limiting groove 15, thereby locking it at the opening of the storage housing 1. This prevents the caster from getting stuck in the gear 3 and the locking strip 10 and being able to rotate and come off under special circumstances.

[0030] Specifically, a toggle plate 16 is rotatably connected to one side of the top of the rotating shaft compartment 2. The toggle plate 16 has an integrally constructed locking strip 10 at one end passing through the rotating shaft compartment 2, and the locking strip 10 and the locking gear 3 form a ratchet structure.

[0031] By adopting the above technical solution, in the unfolded state, the normally locked locking strip 10 is locked in the locking gear 3 to form a self-locking state. When it is necessary to adjust the universal wheel 8, the lever plate 16 can be moved to adjust it.

[0032] Specifically, the bottom end of the connecting bracket 7 is equipped with a swivel wheel 8 that can turn freely.

[0033] By adopting the above technical solution, after removing the caster wheel 8, the box can be dragged by the two caster wheels 8 on one side.

[0034] Specifically, a bottom pad 17 is fixedly connected to the bottom end of the storage housing 1.

[0035] By adopting the above technical solution, the bottom pad 17 contacts the ground to support the entire box.

[0036] Specifically, the bottom end of the bottom pad 17 is flush with the bottom end of the box.

[0037] By adopting the above technical solution, the casters are stored away, so that the bottom of the box is in contact with the ground as a whole instead of just one side. This increases the contact area, spreads the pressure exerted on the box by gravity, and relatively improves its service life.

[0038] The working principle and usage of this utility model are as follows: In the freely adjustable state, the connecting bracket 7 can rotate within the shaft chamber 2 and the driven mounting groove 9 along with the connecting structure of the mounting handle 6 and the coupling 5. This allows the caster 8 to be stored in the storage housing 1 or unfolded. After switching to the correct state, the spring self-resets, causing the locking strip 10 to engage with the locking teeth of the locking gear 3. This limits the rotation of the locking gear 3, the linkage rod 4, the coupling 5, the mounting handle 6, the connecting bracket 7, and the driven mounting groove 9, thus achieving the storage of the casters. This ensures that the bottom of the entire housing contacts the ground, rather than the outer corner, which relatively improves the service life. Furthermore, it reduces the space occupied by the casters during placement, facilitating storage of the housing and preventing damage to the casters from external forces. Rotating the knob 11 drives the threaded sleeve 12 to rotate. This allows the threaded connecting rod 13 to move vertically under the restriction of the limiting plate 14 and the limiting groove 15, thereby locking it at the opening of the housing 1. This prevents the caster from getting stuck in the gear 3 and locking strip 10 and being able to rotate and disengage under special circumstances.

After storing the caster, the bottom of the housing is in contact with the ground as a whole, rather than just one side.
