Description

Technical Field

[0001] This utility model relates to the field of casters, and more particularly to a suitcase caster with brakes and a suitcase. Background Technology

[0002] With the increasing demand for travel, suitcases have become an indispensable piece of equipment for travelers. As a key component of suitcases, casters' flexibility and braking performance directly affect the user experience. Traditional suitcase casters with brakes typically use independent brake blocks or locking mechanisms, which are activated by foot or manual operation, directly acting on the wheel hub or wheel surface to achieve locking. However, existing brake casters have some common problems. First, many brake structures are complex, with many parts, leading to higher production costs and increased failure rates. Second, the unlocking and locking operations of some brake devices are not smooth enough, requiring the user to apply considerable force, or they may become stuck or insecurely locked after long-term use due to wear.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0005] To achieve the above objectives, this utility model provides a luggage caster with brakes, including a wheel seat and wheel bodies located on the left and right sides of the wheel seat. The wheel bodies are rotatable relative to the wheel seat. Multiple locking slots are distributed circumferentially on the inner side of the wheel bodies. The wheel seat is provided with a sliding groove and a slider. The slider is provided with a rotatable locking member. The left and right ends of the locking member are provided with locking parts that connect with the locking slots. The wheel seat is provided with an elastic member that elastically abuts against the locking member. The elastic member applies elastic force to the locking member to keep the locking parts connected to the locking slots. The wheel seat is provided with a positioning locking part located on the sliding path of the slider. The locking member is provided with a locking groove that engages with the positioning locking part. The positioning locking part engages with the locking groove to disengage the locking part from the locking slot.

[0006] Furthermore, the slider has a clearance groove that slides in conjunction with the positioning card.

[0007] Furthermore, the elastic element is a torsion spring, which includes a sleeve portion, a first abutting end, and a second abutting end. The wheel seat is provided with a column for the sleeve portion to connect to. The first abutting end abuts against the locking element, and the second abutting end abuts against the wheel seat.

[0008] Furthermore, the side of the wheel seat is provided with a recessed area, and the elastic element is arranged in the recessed area.

[0009] Furthermore, the wheel seat is provided with a first limiting part and a second limiting part, the first limiting part being used to position the first abutting end, and the second limiting part being used to position the second abutting end.

[0010] Furthermore, the snap-fit ​​part is a cylinder, and the edge of the snap-fit ​​opening has an arc-shaped transition surface.

[0011] This application also provides a suitcase having the suitcase casters described above.

[0012] Compared with the prior art, the advantages of this utility model are: by integrating the slider, rotatable locking element and elastic element into the wheel seat, the braking is achieved by directly engaging the locking parts at both ends of the locking element with the locking slots on the inner side of the wheel body, eliminating the complex connecting rods or independent brake blocks in the traditional structure.

[0018] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] See Figure 1-5This application provides a luggage caster with brakes, which includes a wheel seat 1 and wheel bodies 2 located on the left and right sides of the wheel seat 1. The wheel bodies 2 are rotatable relative to the wheel seat 1. Multiple latches 3 are distributed circumferentially on the inner side of the wheel bodies 2. The wheel seat 1 is provided with a sliding groove 4 and a slider 5. The slider 5 is provided with a rotatable locking member 6. The left and right ends of the locking member 6 are provided with latching parts 7 that connect with the latches 3. The wheel seat 1 is provided with an elastic member that elastically abuts against the locking member 6. The elastic member applies elastic force to the locking member 6 to keep the latching parts 7 connected to the latches 3. This solution integrates the slider 5, the rotatable locking member 6 and the elastic member into the wheel seat 1. The braking is achieved by directly engaging the latching parts 7 at both ends of the locking member 6 with the latches 3 on the inner side of the wheel body 2, eliminating the complex linkages or independent brake blocks in traditional structures. In addition, by abutting the locking member 6 with the elastic member, it is ensured that the latching parts 7 are not easily dislodged from the latches when the user uses the brake. The wheel seat 1 is located on the sliding path of the slider 5 and has a positioning card part 8. The locking member 6 has a card groove 9 that engages with the positioning card part 8. When the positioning card part 8 engages with the card groove 9, the engaging part 7 disengages from the card opening 3. Specifically, the user presses the slider 5 to move the locking member 6 toward the positioning card part 8. When the positioning card part 8 contacts the locking member, it will press against the locking member 6, forcing the locking member 6 to generate a rotational force. At this time, the elastic element will also be compressed and deformed. As the locking member 6 passes the positioning card part 8, when the card groove 9 on the locking member 6 corresponds to the positioning card part 8, the card groove 9 engages with the positioning card part 8. Figure 4 As shown, when the user releases slider 5, slider 5 cannot return to its original position; when the user presses slider 5 again, locking member 6 completely passes over positioning part 8. Losing the supporting force of positioning part 8, the locking member 6 is forced to rotate back under the elastic force of the elastic member, causing positioning part 8 to misalign with slot 9, as shown. Figure 5 As shown, when the slider 5 is released, the locking part 6 and the slider 5 are reset under the action of the elastic part, and the locking part 7 is re-engaged with the bayonet to realize the braking and locking of the vehicle.

[0020] The slider 5 has a clearance slot 51 that slides in conjunction with the positioning card part 8. The clearance slot 51 on the slider 5 slides in conjunction with the positioning card part 8, which further improves the guidance and stability of the slider 5 during movement, avoids jamming or deviation, and makes the braking and unlocking actions smoother and more reliable.

[0021] The elastic element is a torsion spring, which includes a sleeve portion 10, a first abutting end 11, and a second abutting end 12. The wheel seat 1 is provided with a column 13 for the sleeve portion 10 to connect to. The first abutting end 11 abuts against the locking member 6, and the second abutting end 12 abuts against the wheel seat 1. By using a torsion spring as the elastic element, through the structural design of its sleeve portion 10, the first abutting end 11, and the second abutting end 12, it can efficiently and stably transmit elastic force to the locking member 6, ensuring a tight engagement between the locking portion 7 and the locking slot 3.

[0022] The wheel seat 1 has a recessed area 14 on its side, and an elastic element is arranged in the recessed area 14. Arranging the elastic element in the recessed area 14 on the side of the wheel seat 1 effectively utilizes the internal space, avoids interference with other components, and improves the compactness and aesthetics of the overall structure.

[0023] The wheel seat 1 is provided with a first limiting part 15 and a second limiting part 16. The first limiting part 15 is used to position the first abutting end 11, and the second limiting part 16 is used to position the second abutting end 12. By positioning the first abutting end 11 and the second abutting end 12 of the torsion spring by the first limiting part 15 and the second limiting part 16 respectively, the accuracy of the torsion spring installation position is ensured, and the convenience of assembly and product consistency are improved. In addition, the precise limiting design ensures that the torsion spring will not shift or loosen during operation, thereby maintaining the stability and reliability of the braking force.

[0024] The locking part 7 is a cylinder, and the edge of the latch 3 is provided with an arc-shaped transition surface 31. The locking part 7 adopts a cylindrical design, which cooperates with the arc-shaped transition surface 31 at the edge of the latch 3. This can reduce friction and impact during contact, make the locking and disengaging actions smoother, and extend the service life of the component.

[0025] This application also provides a suitcase, wherein the bottom of the suitcase is equipped with the suitcase casters described above at each corner.

[0026] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments.
