Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a rotary brake device. Background Technology

[0002] In medical devices, braking devices are typically used to ensure the stability and safety of the equipment during use. These braking devices can be manual or automatic and are designed to prevent accidental movement of the equipment, ensuring precise operation and patient safety. Traditional medical device braking methods usually use an integrated wheel brake, which is concealed and inconvenient for quick operation. For pedal-operated braking devices, a larger operating space is required.

[0003] Therefore, it is necessary to design a rotary brake device that can self-lock after the brake is released, thereby improving ease of use. Utility Model Content

[0004] To overcome the shortcomings of traditional medical equipment braking methods, which typically use an integrated wheel for braking, making operation concealed and inconvenient for quick operation, and requiring more operating space for pedal-type braking devices, this utility model provides a knob-type braking device that can self-lock after the brake is released, improving ease of use.

[0005] The technical solution is as follows: A knob-type brake device includes a mounting shell, a knob, a gear, a limiting plate, a rack, a guide rail, a brake cable, a brake assembly, and a locking assembly. The knob is rotatably connected to the front of the mounting shell, the gear is connected to the rear of the knob, the limiting plate is connected to the rear of the gear, the guide rail is detachably connected to the bottom of the mounting shell, the rack is slidably connected to the guide rail, the brake cable is connected to the right side of the rack, and the brake cable is equipped with a brake assembly that can self-lock after the brake is released.

[0006] As an improvement to the above solution, the knob has a teardrop-shaped structure.

[0007] As an improvement to the above solution, the brake assembly includes a top ball screw, a brake mounting plate, an anti-disengagement clip, a spring, a brake sheet metal actuator, bolts, a retaining ring pin, a C-ring, a brake disc, and a wheel carrier. The rear of the mounting housing is threaded with two top ball screws on the left and right sides, and a limiting plate engages with the adjacent top ball screw. An anti-disengagement clip is fitted onto the lower part of the brake line, and the brake mounting plate is connected to the lower side of the anti-disengagement clip. A brake sheet metal actuator is fitted onto the lower part of the brake line, and the brake sheet metal actuator is located inside the brake mounting plate. A spring connects the anti-disengagement clip and the brake sheet metal actuator. Two bolts on the lower part of the brake mounting plate are slidably detachable, and both bolts are detachably connected to the brake sheet metal actuator. A retaining ring pin is engaged at the lower part of the brake mounting plate, and a C-ring is engaged on the retaining ring pin, contacting the right side of the brake mounting plate. The wheel carrier is located below the brake mounting plate and is detachably connected to the brake mounting plate. Two brake discs on the left and right sides are connected to the middle of the wheel carrier.

[0008] As an improvement to the above solution, guide grooves are provided on both the left and right sides of the brake mounting plate.

[0009] As an improvement to the above solution, multiple fixing screws are provided on both the left and right sides of the brake mounting plate.

[0010] As an improvement to the above solution, a locking assembly is also included. The locking assembly includes a limit rod and a limit nut. The limit rod is sleeved on the brake cable, and the limit nut is threadedly connected to the lower part of the brake cable. The limit nut contacts the lower side of the limit rod.

[0011] The present invention has the following advantages: 1. By rotating the knob, the gear and rack mesh with each other, driving the brake sheet metal to move downward, so that the snap ring pin engages with the brake disc to brake. At this time, the limit plate engages with the right-side top ball screw, and self-locking is achieved by the top ball screw, which can achieve self-locking after the brake is released, thus improving the ease of use.

[0012] 2. This utility model, by rotating the limiting nut, causes the limiting nut to move downward under the action of the thread, so that the limiting nut no longer contacts the limiting rod. Then, the brake cable is pulled upward on the limiting rod, so that the length of the brake cable reaches a suitable length, and the limiting nut contacts the limiting rod. This achieves the effect of adjusting the length of the brake cable, which is convenient for fitting equipment of different volumes and heights according to different lengths of the brake cable.

The limiting piece 31 is connected to the rear of the gear 3. The guide rail 5 is detachably connected to the bottom of the mounting shell 1. The rack 4 is slidably connected to the guide rail 5. The brake cable 6 is connected to the right side of the rack 4. The brake assembly is installed on the brake cable 6.

[0021] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the brake assembly includes a top ball screw 7, a brake mounting plate 8, an anti-disengagement clip 9, a spring 10, a brake sheet metal actuator 11, a bolt 12, a retaining ring pin 13, a C-ring 14, a brake disc 16, and a wheel frame 15. The rear of the mounting housing 1 is threaded with two top ball screws 7 on the left and right sides. A limiting piece 31 engages with its adjacent top ball screw 7. An anti-disengagement clip 9 is fitted onto the lower part of the brake cable 6. The brake mounting plate 8 is connected to the lower side of the anti-disengagement clip 9. Guide grooves are provided on both the left and right sides of the brake mounting plate 8 for easy guidance. Eight fixing screws are provided on both the left and right sides of the brake mounting plate 8 for easy installation. The lower part of the brake cable 6 is fitted with... A brake sheet metal moving part 11 is connected, which is located inside the brake mounting plate 8. A spring 10 connects the anti-disengagement clip 9 to the brake sheet metal moving part 11. Two sliding bolts 12 are detachably connected to the brake sheet metal moving part 11 at the bottom of the brake mounting plate 8. A retaining spring pin 13 is snapped into the bottom of the brake mounting plate 8. A C-shaped buckle 14 is snapped into the retaining spring pin 13. The C-shaped buckle 14 contacts the right side of the brake mounting plate 8. The wheel frame 15 is located below the brake mounting plate 8 and is detachably connected to the brake mounting plate 8. Two brake discs 16 are connected to the middle of the wheel frame 15.

[0022] like Figure 4 As shown, it also includes a locking assembly, which includes a limit rod 17 and a limit nut 18. The limit rod 17 is sleeved on the brake line 6, and the lower part of the brake line 6 is threadedly connected to the limit nut 18. The limit nut 18 contacts the lower side of the limit rod 17.

[0023] At this time, spring 10 is in the contracted state. When using this device, first install the mounting shell 1, brake mounting plate 8, and wheel frame 15 onto the medical equipment. Then, use the C-shaped buckle 14 to snap the circlip pin 13 onto the brake mounting plate 8. When the driver needs to brake, turn the knob 2 to drive the gear 3 and the limiting plate 31 to rotate, causing the limiting plate 31 to disengage from the left-side top ball screw 7. The gear 3 and rack 4 mesh with each other, driving the rack 4 to move to the right along the guide rail 5. Spring 10 gradually returns to its original state, causing the brake sheet metal moving 11 to move downwards and reset, causing the bolt 12 to move downwards along the guide groove, driving the circlip pin 13 to move downwards, so that the circlip pin 13 and the wheel frame 15... When the brake disc 16 engages for braking, the limiting plate 31 engages with the right-side ball screw 7, which self-locks, allowing for self-locking after the brake is released, thus improving ease of use. When the vehicle body has different dimensions, the limiting nut 18 can be rotated, causing it to move downwards under the action of the thread, so that the limiting nut 18 no longer contacts the limiting rod 17. Then, the brake cable 6 is pulled upwards on the limiting rod 17, so that the length of the brake cable 6 reaches the appropriate length, allowing the limiting nut 18 to contact the limiting rod 17. This allows for adjustment of the length of the brake cable 6, making it easy to adapt to equipment of different dimensions and heights based on the different lengths of the brake cable 6.
