[0002] Casters are a common trolley accessory, typically installed on the base of trolleys, machinery, medical equipment, etc., to facilitate the movement of objects. When the object reaches its destination, the casters need to brake to bring the trolley or equipment to a stop. Currently, with industrial development, there are many types of casters available. Considering the application of casters, the practicality and reliability requirements for the braking function of casters are becoming increasingly stringent; more additional functions are required for casters, such as dustproof and anti-winding functions; ease of cleaning in daily use; higher load-bearing capacity requirements; and longer service life.

[0003] Existing casters still have the following drawbacks: the braking method is limited to locking the wheel or direction, resulting in unreliable braking performance and high noise levels; the caster swivel structure is not flexible in rotation, has low load-bearing capacity, and weak impact resistance; casters are prone to getting tangled in hair, thread, etc. during use; and they easily accumulate dust during daily use, making them difficult to clean.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-6This utility model provides an embodiment of a brake caster with a shell, including a screw rivet 1, a foot bracket 14 at the bottom of the screw rivet 1, a bearing sleeve 3 riveted to the foot bracket 14, a bearing 4 riveted inside the bearing sleeve 3, a directional brake disc 15 fixedly connected to the bottom of the bearing 4, a screw rivet 1 on the bearing 4, and a foot bracket end cap 2 fixedly connected to the lower end of the screw rivet 1. The foot bracket end cap 2 fits against the inner ring end face of the bearing 4. This caster adopts a separate and independent design for the brake pedal 8 and the release pedal 9, utilizing the principles of levers and springs to make braking and releasing the caster more effortless, convenient, and quieter; when braking, it can simultaneously brake the wheel 11 and the direction, and the braking performance is stable. The caster's bracket turntable structure adopts a bearing riveting design, making the caster's directional rotation more flexible, and its load-bearing capacity and impact resistance stronger.

[0025] The tripod 14 is equipped with rivet 5, rivet 6, rivet 7, and rivet 10. A release brake pedal 9 is riveted to rivet 5. A brake pedal 8 and a release brake pedal 9 are riveted to rivet 6. A brake spring 13 and the tripod 14 are riveted to rivet 10. Rivet 7 is riveted to one end of the brake spring 13. A left outer shell 16 is located on one side of the tripod 14, and a right outer shell 17 is located on the other side. Left shell protrusion 1601 is fixedly connected to the left shell 16, and right shell recess 17 is fixedly connected to the right shell 17. Left shell protrusion 1601 is snapped onto right shell recess 1701. Left shell protrusion 1602 is fixedly connected to one side of left shell 16, and right shell protrusion 1702 is fixedly connected to one side of right shell 17. Shell connecting pin 18 is snapped onto left shell 16, and one end of shell connecting pin 18 is snapped onto both left shell 16 and right shell 17. A wheel axle 12 is riveted to the tripod 14, and a wheel 11 is rotatably connected to the wheel axle 12. A second protrusion 1602 on the left shell engages with a square hole on one side of the tripod 14, and a second protrusion 1702 on the right shell engages with a square hole on the other side of the tripod 14. Rivet 5 passes through the release brake pedal 9, rivet 6 passes through the brake pedal 8 and the release brake pedal 9, rivet 10 passes through the brake spring 13 and the tripod 14, and rivet 7 passes through the brake spring 13 and the brake pedal 8. The wheel axle 12... The axle 12 runs through the wheel 11 and the frame 14 passes through the wheel 11. The caster has a left outer shell 16 and a right outer shell 17 to protect the caster and give it an anti-tangling function, preventing hair, lines, film and other debris from getting into the wheel 11 and avoiding damage to the wheel 11. At the same time, the caster is not easy to stick to dust, which is conducive to cleaning. It protects the caster from corrosion and extends the service life of the caster. It also has a reasonable pin connection and buckle connection design, which is not easy to loosen and can protect the caster more effectively and for a longer period of time.

[0026] Working principle: In use, the device is first connected to the object using screws and rivets 1. Screws and rivets 1, the end cap 2 of the caster frame, bearing 4, and the steering brake disc 15 are riveted together as a whole. Bearing 4 is riveted inside bearing sleeve 3, and bearing sleeve 3 is riveted to the caster frame 14. The turntable structure design makes the caster wheels more flexible in direction, with stronger load-bearing capacity and impact resistance. The release brake pedal 9 is riveted to rivet 5, the brake pedal 8 to rivet 6, and the brake spring 13 to rivet 7 and rivet 10, all of which can rotate. The brake spring 13 and the release brake pedal 9 are also riveted to the caster frame 14, both of which can rotate. Wheel 11 is riveted to the bracket 14 via axle 12 and can rotate. When braking is required, pressing the brake pedal 8 causes the release pedal 9 to tilt upwards, and the front rack of the brake spring 13 inserts into the steering brake disc 15, preventing the entire disc from rotating, thus achieving the purpose of stopping the steering. At the same time, the rear of the brake spring 13 presses against the wheel surface, preventing wheel 11 from rotating, thus achieving the purpose of stopping wheel 11. Because the brake spring 13 and the brake pedal 8 work simultaneously, both the steering and wheel 11 are stopped at the same time. When the brake needs to be released, pressing the release pedal 9 reverses the action, causing the brake spring 13 to spring back to its original position, and the front rack of the brake spring 13 engages with the steering brake disc 15. The gear sprocket 15 can be separated without interference, allowing the turntable to rotate; the rear of the brake spring 13 can be separated from the wheel surface without interference, allowing the wheel 11 to rotate. By synchronizing these actions, the brake can be released, thus restoring the caster to its free state. Simultaneously, the bracket 14 has a square hole, and the left outer shell 16 and right outer shell 17 are provided with a left shell protrusion 1602 and a right shell protrusion 1702, respectively, which can be inserted into the square hole on the bracket 14, allowing the left and right outer shells 16 and 17 to be fastened to the bracket 14. The left outer shell 16 has a left shell protrusion 1601, and the right outer shell 17 has a right shell recess 1701. When closed, the left shell protrusion 1601 on the left shell 16 inserts into the right shell recess 1701 on the right shell 17, thus securing the left shell 16 and right shell 17 together. Simultaneously, when the left shell 16 and right shell 17 are closed, the shell connecting pin 18 is inserted. The shell connecting pin 18 surrounds the left shell 16 and right shell 17 in a C-shape, securing them together and preventing separation. The shell connecting pin 18 also has a slot design, which engages with both the left shell 16 and right shell 17, ensuring that the shell connecting pin 18 will not loosen during use, thus providing excellent protection for the casters.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
