It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] When the embodiments of the present invention mention ordinal numbers such as "first" and "second", unless they do express the meaning of order according to the context, they should be understood as being merely for the purpose of distinction.

[0030] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0031] Specific embodiments, such as Figure 1-4 The caster with a one-touch brake locking function shown in the figure comprises: a mounting base 1, on which is provided a mounting shaft 2, and a mounting hole 3 provided on the circumferential side of the mounting shaft 2; a wheel mounting frame 4, which is rotatably provided on the mounting shaft 2; a wheel 5, which is rotatably provided on the wheel mounting frame 4; a rotation locking member 6, which is provided at one end of the mounting shaft 2 extending out of the wheel mounting frame 4, and the rotation locking member 6 is provided with a plurality of locking protrusions 71 arranged along the circumference of the mounting shaft 2; a brake locking member 8, which is rotatably provided on the wheel mounting frame 4 and is located between the wheel 5 and the rotation locking member 6, and the brake locking member 8 is one of the most important components of the caster. The end of the brake lock member 8 is provided with a locking groove 72 corresponding to and matching the locking protrusion 71, and the other end of the brake lock member 8 is provided with a brake plate 73; a one-button driving member 9 is rotatably provided on the wheel mounting frame 4. When the one-button driving member 9 is rotated, the brake lock member 8 can be pushed to flip, so that one end of the brake lock member 8 flips upward until the locking protrusion 71 is located in the locking groove 72, thereby limiting the rotation of the mounting base 1 relative to the wheel mounting frame 4, and the other end of the brake lock member 8 flips downward until the brake plate 73 abuts against the wheel 5, thereby limiting the rotation of the wheel 5 relative to the wheel mounting frame 4. When the one-button driving member is rotated, the brake lock member can be pushed to flip, so that one end of the brake lock member flips upward until the locking protrusion is located in the locking groove, thereby limiting the rotation of the mounting base 1 relative to the wheel mounting frame, and the other end of the brake lock member flips downward until the brake plate abuts against the wheel, thereby limiting the rotation of the wheel relative to the wheel mounting frame, thereby realizing the one-button brake locking function, meeting the needs of different conditions and being more convenient to use.

[0032] Specifically, the one-touch driving member 9 includes a driving mounting portion 91 and two driving protrusions 92 oppositely disposed on either side of the driving mounting portion 91 for pushing the brake lock member 8 to flip. The end of the driving protrusion 92 away from the driving mounting portion 91 is provided with a clamping notch 101. The brake lock member 8 is provided with a clamping protrusion 102 that matches the clamping notch 101. When the one-touch driving member 9 pushes the brake lock member 8 to flip until the locking protrusion 71 is located in the locking groove 72 and the brake plate 73 abuts against the wheel 5, the clamping protrusion 102 extends into the clamping notch 101. When braking, the clamping protrusion 102 is clamped in the clamping notch 101, which limits the one-touch driving member 9 from flipping relative to the brake lock member 8, making the brake more stable.

[0033] In addition, a driving limit portion 11 is provided at one end of the driving mounting portion 91 away from the driving protrusion 92, and the one-button driving member 9 can be turned over until the driving limit portion 11 abuts against the upper end of the wheel mounting bracket 4 to limit the turning of the one-button driving member 9, making it more convenient to use.

[0034] Furthermore, the brake lock member 8 is provided with a brake mounting groove 12, one end of the brake plate 73 is connected to the wall of the brake mounting groove 12, and the other end extends obliquely toward the wheel 5. The brake plate 73 is an elastic plate that can be elastically deformed during braking to achieve a buffering effect.

[0035] More specifically, in order to further improve the braking performance, the brake plate 73 is provided with two parallel braking protrusions 13 at one end close to the wheel 5 .

[0036] Furthermore, in order to make the structure more compact and the brake lock more stable, a clamping plate 14 extending toward the mounting base 1 is provided on the brake lock member 8 and between the locking slot 72 and the brake plate 73, and the wheel mounting frame 4 is tightened by the clamping plate 14.

[0037] Furthermore, the wheel mounting frame 4 is provided with two oppositely arranged hinge holes 15 , and the brake locking member 8 is provided with hinge members 16 corresponding to the two hinge holes 15 .

[0038] Specifically, in order to ensure smooth rotation of the wheel, a rotation bearing 17 is provided on the mounting shaft 2 and between the mounting base 1 and the wheel mounting frame 4 .

[0039] More specifically, there are two locking slots 72, and the mounting base 1 can be rotated relative to the wheel mounting frame 4 until the two locking slots 72 respectively correspond to the two locking protrusions 71, so that the locking direction is more stable.
