Description
Technical Field
[0001] This utility model relates to the field of medical equipment technology, and more specifically, to a braking device, a transport device, and a medical device. Background Technology
[0002] For some large medical devices (such as X-ray imaging equipment), a walking system is usually included to allow staff to move the equipment during use and change its current position. Because large medical equipment requires staff to move it, the equipment usually does not move very fast, and staff can stop moving it when it needs to stop at a certain position.
[0003] During use, the position of the medical device needs to be changed frequently. After stopping the movement of the medical device, it will not remain fixed in one position and may deviate from the intended position.
[0004] Therefore, how to provide a braking device that can fix the medical equipment in a predetermined position after the staff stops pushing it is an urgent problem to be solved. Utility Model Content
[0005] In order to solve or improve the technical problem that the medical device does not remain fixed in a certain position after the medical device is stopped, and may deviate from the intended position, one object of this utility model is to provide a braking device.
[0006] Another objective of this invention is to provide a transportation device.
[0007] Another objective of this invention is to provide a medical device.
[0008] To achieve the above objectives, the first aspect of this utility model provides a braking device, comprising: a frame; a wheel rotatably mounted on the frame; a brake lever movably mounted on the frame; a first brake shaft rotatably mounted on the frame; a brake eccentric wheel connected to the first brake shaft, the brake eccentric wheel abutting against the brake lever; during rotation, the brake eccentric wheel drives the brake lever to move relative to the frame, so that the brake lever approaches or moves away from the wheel; when the brake lever abuts against the wheel, the brake lever is used to limit the rotation of the wheel; a second brake shaft rotatably mounted on the frame, the second brake shaft being connected to the first brake shaft via a transmission assembly; and a pedal connected to the second brake shaft, the pedal being used to drive the second brake shaft to rotate relative to the frame.
[0009] This invention aims to provide a braking device that, after the operator stops pushing the medical equipment, can fix the equipment in a predetermined position and prevent it from shifting, facilitating subsequent operations. Since the position of the medical equipment needs to be frequently changed, the braking device allows for immediate stopping; after releasing the brake, the operator can continue pushing the equipment. The operation is simple, convenient, and quick.
[0010] The operator presses a pedal to rotate the second brake shaft relative to the frame. This second brake shaft, through a transmission assembly, drives the first brake shaft and the brake eccentric wheel to rotate together. During rotation, the brake eccentric wheel moves the brake lever relative to the frame, causing it to move closer to or away from the wheel. When the brake lever is in contact with the wheel, it limits the wheel's rotation. This design ensures that the medical equipment is fixed in a predetermined position and prevents displacement after the operator stops pushing it. The braking device is characterized by its simple structure and few components.
[0011] In some technical solutions, optionally, the frame includes: a chassis; a support arm connected to the chassis; wherein, a second brake shaft passes through the chassis and is rotatably connected to the chassis; and a first brake shaft is rotatably mounted on the support arm.
[0012] In this technical solution, by placing the second brake shaft on the chassis and the first brake shaft on the support arm, it is beneficial to optimize the spatial layout and improve the space utilization rate; it can also avoid interference between transmission components, shorten the power transmission path, and improve the braking response speed.
[0013] In some technical solutions, the frame may optionally include a brake bracket support, which is located on the support arm; wherein the first brake shaft passes through the brake bracket support and is rotatably connected to the brake bracket support.
[0014] In this technical solution, by setting a brake bracket support, it is beneficial to further optimize the spatial layout and improve the space utilization rate; avoid interference between transmission components, and shorten the power transmission path to improve the braking response speed.
[0015] In some technical solutions, the brake bracket support and the support arm can be detachably connected.
[0016] In this technical solution, the detachable connection design makes it convenient for staff to disassemble and assemble the brake bracket support, which is beneficial for maintenance or replacement.
[0017] In some technical solutions, optionally, the brake eccentric wheel is connected to one end of the first brake shaft, and the transmission assembly is connected to the other end of the first brake shaft; the number of brake bracket supports is one, and one brake bracket support is located between the brake eccentric wheel and the transmission assembly.
[0018] In this technical solution, the brake eccentric wheel and the transmission assembly are respectively located at both ends of the first brake shaft, and the brake bracket support is located between the brake eccentric wheel and the transmission assembly. This design method is beneficial for optimizing the spatial layout, reducing the space occupied by the brake bracket support, and effectively reducing the possibility of motion interference between the brake bracket support and other components.
[0019] In some technical solutions, the transmission assembly may optionally include: a first brake sway member disposed on a first brake shaft; a second brake sway member disposed on a second brake shaft; and at least two brake cables, one end of each brake cable being connected to the first brake sway member and the other end of each brake cable being connected to the second brake sway member.
[0020] In this technical solution, the symmetrical arrangement of at least two brake ropes ensures that the first brake swing element and the second brake swing element are subjected to uniform force, avoiding the swing element from tilting or the shaft from bending due to unilateral force during single-rope transmission, and ensuring that the braking force is transmitted without eccentric load.
[0021] In some technical solutions, optionally, the brake bracket support is provided with a mounting cavity, and a bearing is provided in the mounting cavity, through which the first brake shaft passes.
[0022] In this technical solution, by setting bearings, on the one hand, the first brake shaft and the brake bracket support can be rotated; on the other hand, the wear is effectively reduced, which helps to improve the service life.
[0023] In some technical solutions, optionally, the support arm is provided with a stepped hole, and the brake rod passes through the stepped hole; the braking device also includes: a reset elastic element, provided in the stepped hole, one end of the reset elastic element abuts against the stepped surface of the stepped hole, and the other end of the reset elastic element abuts against the brake rod.
[0024] In this technical solution, by setting a stepped hole and a reset elastic element, it can be ensured that the brake lever always has a tendency to move away from the wheel body, and that the brake lever is always in contact with the brake eccentric wheel. During the rotation of the brake eccentric wheel, it drives the brake lever to move relative to the frame, so that the brake lever moves closer to or away from the wheel body; when the brake lever is in contact with the wheel body, the brake lever is used to limit the rotation of the wheel body.
[0025] The second aspect of this utility model provides a transportation device, including: a braking device as described in any of the above technical solutions; and a mounting base connected to the frame of the braking device.
[0026] Since the transport device includes the braking device in any of the above technical solutions, it has the beneficial effects of any of the above technical solutions, which will not be elaborated here.
[0027] The third aspect of this utility model provides a medical device, including: the transport device described in the above technical solution; and a C-arm X-ray machine connected to the mounting base of the transport device.
[0028] Since the medical device includes the transport device described in the above technical solution, it has the beneficial effects of the above technical solution, which will not be elaborated here.

Detailed Implementation
[0037] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this utility model, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.
[0038] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, embodiments of the present invention may be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0039] For some large medical devices (such as X-ray imaging equipment), a walking system is usually included to allow staff to move the equipment during use and change its current position. Because large medical equipment requires staff to move it, the equipment usually does not move very fast, and staff can stop moving it when it needs to stop at a certain position.
[0040] It should be noted that X-ray imaging equipment includes C-arm X-ray machines. C-arm X-ray machines are mainly used in orthopedics for bone setting, reduction, and nailing, and in surgery for removing foreign bodies, cardiac catheterization, pacemaker implantation, some interventional treatments, some angiography and local radiography. In addition, they can be used in conjunction with ozone therapy for pain management, needle knife therapy, and gynecological fallopian tube guidance surgery.
[0041] During use, the position of the medical device needs to be frequently changed; therefore, the medical device is not equipped with a limit device. After the medical device is stopped, it will not remain fixed in a certain position and may deviate from the intended position.
[0042] Therefore, how to provide a braking device that can fix the medical equipment in a predetermined position after the staff stops pushing it is an urgent problem to be solved.
[0043] This utility model aims to provide a braking device, a transport device, and a medical device. After the operator stops pushing the medical device, the braking device can fix the medical device in a predetermined position and prevent it from shifting, facilitating subsequent operations. Since the position of the medical device needs to be frequently changed, the braking device allows for immediate stopping. After releasing the braking device, the operator can continue pushing the medical device. The operation is simple, convenient, and quick.
[0044] The operator presses a pedal to rotate the second brake shaft relative to the frame. This second brake shaft, through a transmission assembly, drives the first brake shaft and the brake eccentric wheel to rotate together. During rotation, the brake eccentric wheel moves the brake lever relative to the frame, causing it to move closer to or away from the wheel. When the brake lever is in contact with the wheel, it limits the wheel's rotation. This design ensures that the medical equipment is fixed in a predetermined position and prevents displacement after the operator stops pushing it. The braking device is characterized by its simple structure and few components.
[0045] The following reference Figures 1 to 5 This invention describes braking devices, transport devices, and medical devices provided according to some embodiments of the present invention.
[0046] In one embodiment of this utility model, such as Figure 1 As shown, the braking device 1 includes a frame 10, a wheel 11, a brake lever 12, a first brake shaft 13, a brake eccentric wheel 14, a second brake shaft 15, and a pedal 17.
[0047] Wheel 11 is rotatably mounted on frame 10. Brake lever 12 is movably mounted on frame 10. First brake shaft 13 is rotatably mounted on frame 10. Brake eccentric wheel 14 is connected to first brake shaft 13, and brake eccentric wheel 14 abuts against brake lever 12.
[0048] During rotation, the brake eccentric wheel 14 drives the brake lever 12 to move relative to the frame 10, causing the brake lever 12 to move closer to or further away from the wheel body 11. When the brake lever 12 is in contact with the wheel body 11, the brake lever 12 is used to limit the rotation of the wheel body 11.
[0049] The second brake shaft 15 is rotatably mounted on the frame 10, and the second brake shaft 15 is connected to the first brake shaft 13 via a transmission assembly 16. The pedal 17 is connected to the second brake shaft 15, and the pedal 17 is used to drive the second brake shaft 15 to rotate relative to the frame 10.
[0050] The frame 10, relative to the wheel 11, brake lever 12, first brake shaft 13, and second brake shaft 15, primarily serves as a mounting carrier. It should be noted that the frame 10 can be of any shape depending on the actual requirements. Furthermore, the frame 10 can be composed of multiple different supports (such as chassis 102, support arms 104, etc.). For example, the first brake shaft 13 can be mounted on one support, and the second brake shaft 15 on another.
[0051] The wheel 11 is capable of rotating relative to the frame 10. When the brake lever 12 is not in contact with the wheel 11, the operator can push the medical device 3 to change its current position. When the brake lever 12 is in contact with the wheel 11, the brake lever 12 can limit the wheel 11 from continuing to rotate, so that the medical device 3 is fixed in the predetermined position and does not shift position.
[0052] The first brake shaft 13 can rotate relative to the frame 10. During the rotation of the first brake shaft 13, the first brake shaft 13 can drive the brake eccentric wheel 14 to rotate together. Since the brake eccentric wheel 14 is always in contact with the brake lever 12, during the rotation of the brake eccentric wheel 14, the brake lever 12 is driven to move relative to the frame 10, so that the brake lever 12 moves closer to or away from the wheel body 11.
[0053] Power is transmitted sequentially through pedal 17 to the second brake shaft 15, the first brake shaft 13, the brake eccentric wheel 14, and the brake lever 12; the brake lever 12 restricts the rotation of the wheel 11. The braking device 1 adopts a mechanical braking structure instead of a hydraulic structure, which helps to simplify the structure and reduce the number of parts.
[0054] This invention aims to provide a braking device 1 that, after the operator stops pushing the medical device 3, can fix the medical device 3 in a predetermined position and prevent it from shifting, facilitating subsequent operations. Since the position of the medical device 3 needs to be frequently changed, the braking device 1 allows for immediate stopping. After releasing the braking device 1, the operator can continue pushing the medical device 3. The operation is simple, convenient, and quick.
[0055] When the operator presses pedal 17, it drives the second brake shaft 15 to rotate relative to the frame 10. The second brake shaft 15, through transmission assembly 16, drives the first brake shaft 13 and the brake eccentric wheel 14 to rotate together. During rotation, the brake eccentric wheel 14 drives the brake lever 12 to move relative to the frame 10, causing the brake lever 12 to move closer to or away from the wheel 11. When the brake lever 12 is in contact with the wheel 11, it restricts the rotation of the wheel 11. This design allows the medical device 3 to be fixed in a predetermined position without displacement after the operator stops pushing it. The brake device 1 is characterized by its simple structure and few parts.
[0056] In some embodiments, the pedal 17 is optionally located at one end of the second brake shaft 15, so that the staff can step on the pedal 17 on one side of the medical device 3 to achieve the function of braking and stopping immediately.
[0057] In some embodiments, the number of pedals 17 may be two. Of the two pedals 17, one pedal 17 is located at one end of the second brake shaft 15, and the other pedal 17 is located at the other end of the second brake shaft 15.
[0058] By setting the two pedals 17 at both ends of the second brake shaft 15, staff can step on the pedals 17 from both sides of the medical device 3, making it more convenient and practical.
[0059] In one specific embodiment, there is one second brake shaft 15 and two pedals 17. Additionally, there are two brake levers 12, two first brake shafts 13, and two brake eccentric wheels 14. Each brake eccentric wheel 14 is connected to a corresponding first brake shaft 13, and each brake eccentric wheel 14 abuts against a corresponding brake lever 12.
[0060] In other words, by pressing either pedal 17, two sets of brake assemblies can be activated simultaneously. Each set of brake assemblies includes a first brake shaft 13, a brake eccentric wheel 14, and a brake lever 12.
[0061] This design allows the medical device 3 to be fixed in a predetermined position and prevent positional displacement after the staff stops pushing it, thus ensuring an immediate braking and stopping effect.
[0062] In some embodiments, optionally, such as Figure 1 As shown, the frame 10 includes a chassis 102 and a support arm 104. The support arm 104 is connected to the chassis 102.
[0063] The chassis 102, relative to the second brake shaft 15 and the support arm 104, mainly serves as a mounting carrier. The second brake shaft 15 passes through the chassis 102 and is rotatably connected to the chassis 102. The second brake shaft 15 can rotate relative to the chassis 102.
[0064] Optionally, the chassis 102 is provided with a first weight-reduction hole. The first weight-reduction hole mainly serves to reduce weight.
[0065] The number of first weight-reducing holes is at least one; that is, there can be one, two, or more first weight-reducing holes, which can be flexibly set according to actual needs.
[0066] Optionally, the support arm 104 is a cantilever frame structure. The support arm 104 is detachably connected to the chassis 102, which facilitates disassembly and assembly by workers and is beneficial for maintenance or replacement.
[0067] In one specific embodiment, a flange is provided at one end of the support arm 104. The support arm 104 is bolted to the chassis 102 via the flange to enable quick assembly and disassembly of the support arm 104.
[0068] Optionally, the support arm 104 is provided with a second weight-reducing hole. The second weight-reducing hole mainly serves to reduce weight.
[0069] The number of second weight-reducing holes is at least one, meaning that the first weight-reducing hole can be one, two, or more, and can be flexibly set according to actual needs.
[0070] The first brake shaft 13 is rotatably mounted on the support arm 104. The first brake shaft 13 is capable of rotating relative to the support arm 104.
[0071] The first brake shaft 13 and the second brake shaft 15 are connected by a transmission assembly 16. When the operator steps on the pedal 17, the second brake shaft 15 rotates relative to the frame 10, and the second brake shaft 15 drives the first brake shaft 13 to rotate together through the transmission assembly 16.
[0072] By placing the second brake shaft 15 on the chassis 102 and the first brake shaft 13 on the support arm 104, it is beneficial to optimize the spatial layout and improve the space utilization rate; it can also avoid interference between the transmission components 16, while shortening the power transmission path and improving the braking response speed.
[0073] In some embodiments, optionally, such as Figure 1 As shown, the frame 10 also includes a brake bracket support 106. The brake bracket support 106 is disposed on the support arm 104. The first brake shaft 13 passes through the brake bracket support 106 and is rotatably connected to the brake bracket support 106. The first brake shaft 13 is capable of rotating relative to the brake bracket support 106.
[0074] The support arm 104, relative to the brake bracket support 106, mainly serves as a mounting carrier. The brake bracket support 106, relative to the first brake shaft 13, mainly serves as a mounting carrier.
[0075] It should be noted that the brake bracket support 106 can be of any shape, such as L-shaped. The brake bracket support 106 can be set at any position on the support arm 104, such as at the top of the support arm 104.
[0076] By setting up the brake bracket support 106, it is beneficial to further optimize the spatial layout and improve the space utilization rate; avoid interference between the transmission components 16, and shorten the power transmission path to improve the braking response speed.
[0077] In some embodiments, the brake bracket 106 and the support arm 104 are optionally detachably connected.
[0078] The detachable connection design makes it easy for staff to disassemble and assemble the brake bracket 106, which is beneficial for maintenance or replacement.
[0079] Optionally, the brake bracket support 106 and the support arm 104 are detachably connected by bolts, screws, pins or other types of connectors.
[0080] In one specific embodiment, the brake bracket support 106 and the support arm 104 are detachably connected by bolts, which is easy to operate and convenient.
[0081] In one specific embodiment, the brake bracket support 106 and the support arm 104 are detachably connected by screws, which is easy to operate and convenient.
[0082] In one specific embodiment, the brake bracket support 106 and the support arm 104 are detachably connected by a pin, which is easy to operate and convenient.
[0083] In some embodiments, optionally, such as Figure 1 As shown, the brake eccentric wheel 14 is connected to one end of the first brake shaft 13, and the transmission assembly 16 is connected to the other end of the first brake shaft 13. There is one brake bracket support 106, which is located between the brake eccentric wheel 14 and the transmission assembly 16.
[0084] Optionally, the brake eccentric wheel 14 is fixed to one end of the first brake shaft 13 by a flat key or fastening screw, and its rim profile is an eccentric arc structure that abuts against the end of the brake lever 12.
[0085] The brake eccentric wheel 14 and the transmission assembly 16 are respectively located at both ends of the first brake shaft 13, and the brake bracket support 106 is located between the brake eccentric wheel 14 and the transmission assembly 16. This design is beneficial for optimizing the spatial layout, reducing the space occupied by the brake bracket support 106, and effectively reducing the possibility of motion interference between the brake bracket support 106 and other components.
[0086] In related technologies, the first brake shaft is supported by two brake brackets. One brake bracket is located at one end of the first brake shaft, and the other brake bracket is located at the other end of the first brake shaft.
[0087] The design of two brake brackets takes up a lot of space, is inconvenient to disassemble and maintain, and the supporting structure for implementing the braking function is also inconvenient to adjust the braking force due to the obstruction of the brake brackets.
[0088] In the technical solution defined by this utility model, there is only one brake bracket support 106, meaning that the brake bracket support 106 provides only one support point for the first brake shaft 13. This helps reduce the space occupied by the brake bracket support 106 and effectively reduces the possibility of movement interference between the brake bracket support 106 and other components. Furthermore, providing only one support point for the brake bracket support 106 frees up installation space, facilitating brake force adjustment and disassembly for maintenance, thus providing good adaptability. During braking, the steel wire rope (a specific form of brake rope 166) releases a free force during tension, significantly improving the brake pedal feel.
[0089] In some embodiments, optionally, such as Figure 1 As shown, the transmission assembly 16 includes a first brake sway 162, a second brake sway 164, and at least two brake cables 166. The first brake sway 162 is located on a first brake shaft 13. The second brake sway 164 is located on a second brake shaft 15. One end of each brake cable 166 is connected to the first brake sway 162, and the other end of each brake cable 166 is connected to the second brake sway 164.
[0090] Optionally, the first brake swivel 162 and the first brake shaft 13 are detachably connected, which facilitates disassembly and assembly by staff and is beneficial for maintenance or replacement.
[0091] Optionally, the first brake swivel 162 and the first brake shaft 13 are detachably connected by bolts, screws, pins or other types of connectors.
[0092] In one specific embodiment, the first brake swivel 162 and the first brake shaft 13 are detachably connected by bolts, which is easy to operate and convenient.
[0093] In one specific embodiment, the first brake swivel 162 and the first brake shaft 13 are detachably connected by screws, which is easy to operate and convenient.

[0096] Optionally, the second brake swivel 164 and the second brake shaft 15 are detachably connected by bolts, screws, pins or other types of connectors.

[0098] In one specific embodiment, the second brake swivel 164 and the second brake shaft 15 are detachably connected by screws, which is easy to operate and convenient.
[0099] In one specific embodiment, the second brake swivel 164 and the second brake shaft 15 are detachably connected by a pin, which is easy to operate and convenient.
[0100] In one specific embodiment, the brake rope 166 is a steel wire rope.
[0101] It should be emphasized that the number of brake ropes 166 is at least two, that is, there can be one, two or more brake ropes 166. Considering the transmission efficiency between the first brake shaft 13 and the second brake shaft 15, the braking response speed, the size of the hole occupied, the cost and other factors, the brake ropes 166 can be flexibly set according to actual needs.
[0102] The symmetrical arrangement of at least two brake ropes 166 ensures that the first brake element 162 and the second brake element 164 are subjected to uniform force, avoiding the tilting of the element or the bending of the shaft due to unilateral force during single-rope transmission, and ensuring that the braking force is transmitted without eccentric load.
[0103] In some embodiments, the support arm 104 is optionally provided with a guide constraint hole 1041. The brake rope 166 passes through the guide constraint hole 1041. The guide constraint hole 1041 mainly serves to guide and limit movement.
[0104] In some embodiments, optionally, the support arm 104 is provided with an adapter 181. A brake cable 166 passes through the adapter 181. The two ends of the brake cable 166 are respectively connected to the first brake sway 162 and the second brake sway 164. The adapter 181 mainly serves to change the direction of the brake cable 166, thereby reducing the power transmission path.
[0105] In some embodiments, optionally, such as Figure 3 As shown, the brake bracket support 106 is provided with a mounting cavity 1062, and a bearing 182 is provided in the mounting cavity 1062. The first brake shaft 13 passes through the bearing 182.
[0106] By setting the bearing 182, on the one hand, the first brake shaft 13 and the brake bracket support 106 can be rotatably connected; on the other hand, the wear is effectively reduced, which is conducive to improving the service life.
[0107] Optionally, the number of bearings 182 is at least one, that is, there can be one, two or more bearings 182. The bearings 182 can be flexibly configured according to actual needs.

[0109] In some embodiments, optionally, such as Figure 2 As shown, the support arm 104 is provided with a stepped hole 1042, and the brake lever 12 passes through the stepped hole 1042.
[0110] The braking device 1 also includes a reset elastic element 183. The reset elastic element 183 is disposed in the stepped hole 1042, one end of the reset elastic element 183 abuts against the stepped surface 1043 of the stepped hole 1042, and the other end of the reset elastic element 183 abuts against the brake lever 12.
[0111] Optionally, the stepped hole 1042 includes a first hole and a second hole. The dimensions of the first hole and the second hole are different to form a stepped structure. The connecting wall between the first hole and the second hole is a stepped surface 1043.
[0112] The brake lever 12 passes through the first hole and the second hole, and the brake lever 12 can move relative to the support arm 104.
[0113] In one specific embodiment, the diameter of the first hole is larger than the diameter of the second hole, and the first hole is located above the second hole.
[0114] The reset elastic element 183 is disposed in the first hole. One end of the reset elastic element 183 abuts against the stepped surface 1043, and the other end abuts against the brake lever 12.
[0115] In one specific embodiment, the reset elastic element 183 is a reset spring, which is sleeved on the brake lever 12. The reset spring is located in the first hole, with one end abutting against the stepped surface 1043 and the other end abutting against the brake lever 12.
[0116] By providing the stepped hole 1042 and the reset elastic element 183, it can be ensured that the brake lever 12 always has a tendency to move away from the wheel body 11, and that the brake lever 12 always abuts against the brake eccentric wheel 14. During the rotation of the brake eccentric wheel 14, it drives the brake lever 12 to move relative to the frame 10, so that the brake lever 12 moves closer to or away from the wheel body 11; when the brake lever 12 abuts against the wheel body 11, the brake lever 12 is used to limit the rotation of the wheel body 11.
