Description

Technical Field

[0001] The present application relates to the technical field of drag chains, and in particular to a drag chain mechanism and medical equipment. Background Art

[0002] A drag chain is a device used to restrain pipes such as cables, air compressor pipes and oil pressure pipes. The pipes are usually placed in the drag chain so that they can move along with the drag chain along a set trajectory. The drag chain can protect and pull the pipes, and prevent the pipes from getting entangled, worn, pulled off and scattered during movement. It is widely used in industrial automation and medical equipment.

[0051] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0052] A drag chain is a device used to restrain pipes such as cables, air compressor pipes and oil pressure pipes. The pipes are usually placed in the drag chain so that they can move along with the drag chain along a set trajectory. The drag chain can protect and pull the pipes, and prevent the pipes from getting entangled, worn, pulled off and scattered during movement. It is widely used in industrial automation and medical equipment.

[0053] However, during the movement of the drag chain, the drag chain will produce friction with other objects (such as the ground on which the drag chain is placed). A large amount of debris generated by the friction will float everywhere, affecting the cleanliness of the environment, making it difficult to use the drag chain in occasions with high cleanliness requirements. For example, when used in an operating room, the fallen debris may cause the risk of infection to the patient during the operation.

[0054] The present application provides a drag chain mechanism and medical equipment to solve the problem in related technologies that during the movement of the drag chain, the drag chain will produce friction with other objects, and a large amount of debris generated by the friction will float everywhere, affecting the cleanliness of the environment, making it difficult to use the drag chain in occasions with high cleanliness requirements.

[0055] In a first aspect, the present application provides a drag chain mechanism 10, such as Figure 1 and Figure 2 As shown, the drag chain mechanism 10 includes a box body 20 , a drag chain 30 , an adapter 40 and a sealing member 50 .

[0056] Among them, the box body 20 includes a bottom plate 21 and a peripheral side plate 22 arranged around the bottom plate 21. The peripheral side plate 22 is connected to the bottom plate 21 to define a receiving cavity 23. The peripheral side plate 22 has an opening 24 extending in the first direction XX, and the first direction XX is parallel to the horizontal plane. It can be understood that the horizontal plane refers to a plane composed of horizontal parallel lines in fields such as mathematics and mechanical drawing, and the horizontal plane is perpendicular to the gravity direction of the box body 20. The box body 20 is used to provide a receiving space for the drag chain 30, and the drag chain 30 can be stored in the receiving cavity 23 of the box body 20. When using the drag chain mechanism 10, the bottom plate 21 of the box body 20 faces downward, and the box body 20 can be installed on the ceiling for use. Of course, the bottom plate 21 can also be installed on the ground so that the box body 20 is placed on the ground for use, or the box body 20 can be installed on other devices for use.

[0057] The drag chain 30 is located in the receiving cavity 23. The drag chain 30 has a connecting end 31 and a movable end 32, and the connecting end 31 is connected to the box body 20. The drag chain 30 is used to place and restrain pipes such as cables, air pressure pipes, and oil pressure pipes, so that the pipes can move along with the drag chain 30 along a set track. The drag chain 30 is usually a long strip-shaped structure. Of course, according to actual needs, the drag chain 30 can also be of other shapes. The connecting end 31 and the movable end 32 of the drag chain 30 are respectively the two ends of the drag chain 30. The connecting end 31 of the drag chain 30 is used to realize the connection with the box body 20. The movable end 32 of the drag chain 30 is a movable end, which can drive the part of the drag chain 30 between the movable end 32 and the connecting end 31 to move (such as Figure 3 , the movable end 32 can move to the position shown in Figure 3 ), thereby driving the pipes to move along with the drag chain 30 along a set track.

[0058] The adapter 40 passes through the opening 24. The first end 41 of the adapter 40 is connected to the movable end 32, and the second end 42 of the adapter 40 is located outside the receiving cavity 23 and is used to connect to the movable device 81. The adapter 40 is used to drive the movable end 32 to move along the first direction XX. The adapter 40 is used to realize the connection between the drag chain 30 and the movable device 81. The movable device 81 is located outside the receiving cavity 23. The movable device 81 can be a trolley. When the movable device 81 moves along the first direction XX, it drives the adapter 40 and the movable end 32 of the drag chain 30 to move along the first direction XX. At the same time, the movable device 81 can be used to provide a limit for the adapter 40 and the movable end 32 to prevent the adapter 40 and the movable end 32 from moving in a direction different from the first direction XX (such as the vertical direction and Figure 1 the width direction of the box body 20 in

[0059] The seal 50 is disposed at the opening 24 and is arranged to avoid the adapter 40. The two ends of the seal 50 arranged along the first direction XX are connected to the box body 20 to enclose at least part of the opening 24. It should be noted that the seal 50 is arranged to avoid the adapter 40, which means that the seal 50 avoids the spatial area formed by the outer contour of the adapter 40, so that the adapter 40 can move along the first direction XX, preventing the movement of the adapter 40 in the first direction XX from being blocked by the seal 50 and causing the adapter 40 to jam. The two ends of the seal 50 can be directly connected to the box body 20 by means such as bonding, or the two ends of the seal 50 can also be connected to the box body 20 through connecting parts such as fixing brackets.

[0060] It should be noted that in this application, the drag chain 30 is received in the receiving cavity 23 of the box body 20 through the box body 20, so as to separate the drag chain 30 from objects such as the bottom surface, thereby preventing the drag chain 30 from rubbing against objects such as the bottom surface. Even if the drag chain 30 rubs against the box body 20, the debris generated by the friction will be blocked by the box body 20, so that the debris is received in the receiving cavity 23 and deposited on the bottom plate 21 under the action of gravity. The adapter 40 can be connected to the drag chain 30 through the opening 24, and then drive the drag chain 30 to move, so that the drag chain 30 can move normally. And in combination with the seal 50 enclosing at least part of the opening 24, the seal 50 can block the debris in the receiving cavity 23 from being discharged through the opening 24, thereby preventing the debris in the receiving cavity 23 from floating everywhere during the movement of the drag chain 30 and the adapter 40 and affecting the cleanliness of the environment. Therefore, the drag chain 30 structure of this application can be applied to occasions with high cleanliness requirements (such as operating rooms, dust-free workshops, etc.).

[0061] It should also be noted that the box body 20 can be in a long strip shape, a cylindrical shape or other shapes. When the box body 20 is in a long strip shape, the first direction XX is parallel to the length direction of the box body 20, and the first direction XX is a straight line direction. At this time, the adapter 40 and the movable end 32 of the drag chain 30 can perform a linear reciprocating motion along the first direction XX. When the box body 20 is in a cylindrical shape, the first direction XX is parallel to the circumferential direction of the box body 20, and the first direction XX is a curved line direction. At this time, the adapter 40 and the movable end 32 of the drag chain 30 can perform a curved reciprocating motion along the first direction XX.

[0062] In some embodiments, the adapter 40 bypasses the seal 50 on one side of the seal 50 in the vertical direction, so that the seal 50 avoids the adapter 40, enabling the adapter 40 to move smoothly along the first direction XX, preventing the movement of the adapter 40 in the first direction XX from being blocked by the seal 50 and causing the adapter 40 to jam. Among them, the vertical direction refers to the direction perpendicular to the horizontal plane, and the vertical direction is parallel to the gravity direction of the box body 10, so as to Figure 1Taking the shown perspective as an example, the vertical direction is parallel to the thickness direction of the box body 10. When the opening 24 is used as the notch of the accommodating cavity 23, the vertical direction is perpendicular to the notch depth direction of the accommodating cavity 23. Among them, the adapter 40 can bypass the seal 50 on the upper side or the lower side of the seal 50. More specifically, the second end portion 42 can be located on one side of the seal 50 along the vertical direction, so that the adapter 40 can bypass the seal 50 on one side of the seal 50 along the vertical direction.

[0063] In other embodiments, an avoidance opening extending along the first direction XX can also be formed in the seal 50, and the adapter 40 is inserted through the avoidance opening, so that the seal 50 can avoid the adapter 40; an avoidance opening extending along the first direction XX and penetrating the adapter 40 can also be formed in the adapter 40, and the seal 50 passes through the avoidance opening, so that the seal 50 can avoid the adapter 40; it can also be arranged that the seal 50 includes a first part 51 and a second part, the first part 51 and the second part are respectively located on both sides of the adapter 40 along the first direction XX, and can be deformed, so that the seal 50 can avoid the adapter 40. When the adapter 40 moves along the first direction XX, one of the first part 51 and the second part is stretched and the other is compressed.

[0064] In some embodiments, the positive projection of the inner wall surface of the opening 24 on the first plane P is located between the two ends of the positive projection of the seal 50 on the first plane P arranged along the first direction XX. The first plane P is parallel to the first direction XX and parallel to the vertical direction. It can be understood that the length of the seal 50 along the first direction XX is greater than the length of the opening 24 along the first direction XX, and the two ends of the seal 50 arranged along the first direction XX can seal the two ends of the opening 24, so that more parts of the opening 24 can be sealed by the seal, and further prevent the debris in the accommodating cavity 23 from being discharged from the opening 24.

[0065] In some embodiments, the adapter 40 is spaced from the inner side surface and the outer side surface of the box body 20, that is, all parts of the adapter 40 are not in contact with the inner side surface and the outer side surface of the box body 20, preventing the adapter 40 from rubbing against the box body 20 during movement to generate debris. The adapter 40 can be suspended by the movable device 81, so that the adapter 40 is not in contact with the inner side surface and the outer side surface of the box body 20.

[0066] As Figures 4 to 6 As shown, in some embodiments of the present application, the first end portion 41 and the second end portion 42 are arranged at intervals along the vertical direction, and the seal 50 can be deformed; the adapter 40 further includes a connecting portion 43, and both ends of the connecting portion 43 are respectively connected to the first end portion 41 and the second end portion 42. The first part 51 of the seal 50 bypasses the connecting portion 43 on the side away from the accommodating cavity 23, so that the seal 50 avoids the adapter 40.

[0067] It is understandable that when the second end portion 42 is lower than the first end portion 41, the seal 50 is located above the second end portion 42; when the second end portion 42 is higher than the first end portion 41, the seal 50 is located below the second end portion 42; the first end portion 41, the second end portion 42 and the connecting portion 43 are connected to form a stepped structure, which facilitates the seal 50 to bypass the connecting portion 43 from the side of the connecting portion 43 away from the accommodating cavity 23, so that the seal 50 can more conveniently avoid the adapter 40. The connecting member can undergo elastic deformation or plastic deformation. The first portion 51 is the portion of the seal 50 that bypasses the adapter 40. During the movement of the adapter 40 in the first direction XX, the connecting portion 43 pushes up the portion of the seal 50 opposite to the position of the connecting portion 43 away from the accommodating cavity 23 to form the first portion 51, so that the portions at different positions on the seal 50 form the first portion 51. As Figure 4 shown, when the adapter 40 is located at a position close to the left end of the box body 20, the portion of the seal 50 close to the left end of the box body 20 forms the first portion 51; as Figure 4 shown, when the adapter 40 is located at a position close to the right end of the box body 20, the portion of the seal 50 close to the right end of the box body 20 forms the first portion 51.

[0068] In some embodiments of the present application, the drag chain mechanism 10 further includes a limit frame 60. The limit frame 60 is located on the side of the connecting portion 43 away from the accommodating cavity 23 and is connected to the adapter 40. A limit channel 61 is provided on the side of the limit frame 60 facing away from the connecting portion 43. The first portion 51 passes through the limit channel 61 to bypass the connecting portion 43. The limit channel 61 can prevent the seal 50 from moving vertically, thereby preventing the opening 24 from opening a large gap when the adapter 40 moves in the first direction XX, and can prevent the seal 50 from winding around the adapter 40 and causing the adapter 40 to jam.

[0069] Furthermore, both ends of the limit frame 60 extend along the circumferential direction of the connecting portion 43 and respectively extend to both sides of the connecting portion 43 in the first direction XX. The limit channel 61 extends along the extending direction of the limit frame 60 to both ends of the limit frame 60, so that the length of the limit channel 61 is longer, and thus the length of the first portion 51 restricted by the limit channel 61 is longer, and the restraint on the seal 50 is stronger, which can better prevent the opening 24 from opening a large gap when the adapter 40 moves in the first direction XX due to the vertical movement of the seal 50.

[0070] Specifically, continue to refer to Figures 4 to 6As shown, the limiting frame 60 includes a first limiting plate 62 and a second limiting plate 63; the first limiting plate 62 is connected to the adapter 40; the second limiting plate 63 is located on the side of the first limiting plate 62 away from the second end 42, and a limiting channel 61 is defined between the second limiting plate 63 and the first limiting plate 62. The first limiting plate 62 and the second limiting plate 63 are two plate structures arranged opposite to each other. When the first part 51 of the sealing member 50 is located in the limiting channel 61 formed between the second limiting plate 63 and the first limiting plate 62, the first part 51 is sandwiched between the first limiting plate 62 and the second limiting plate 63. The first limiting plate 62 and the second limiting plate 63 can be used to prevent the first part 51 from moving vertically, thereby preventing the sealing member 50 from moving vertically.

[0071] The first limiting plate 62 may be located below the second limiting plate 63, and the top surface of the first limiting plate 62 is lower than the bottom wall surface of the opening 24. It is understandable that when part of the sealing member 50 is lifted up by the connecting portion 43 to form the first portion 51, part of the opening 24 may be opened to form a smaller gap, and the first limiting plate 62 may receive the debris discharged from the gap to prevent the debris from being scattered everywhere.

[0072] In some embodiments, the spacing between the first limiting plate 62 and the second limiting plate 63 may be equal to the width of the seal 50 , so that the width of the limiting channel 61 is equal to the width of the seal 50 , thereby providing a better limiting effect on the seal 50 .

[0073] In some embodiments, avoidance openings may be provided on the first limiting plate 62 and the second limiting plate 63 at positions corresponding to the first portion 51 to reduce friction between the first portion 51 and the first limiting plate 62 and the second limiting plate 63 .

[0074] In some embodiments of the present application, the limit frame 60 also includes a first limit column 64, which is located in the limit channel 61 and is connected to at least one of the first limit plate 62 and the second limit plate 63. The first part 51 bypasses the first limit column 64 on the side of the first limit column 64 close to the accommodating cavity 23 to avoid the first limit column 64. The first limit column 64 can be used to provide a limit for the first part 51 to prevent the first part 51 from moving away from the accommodating cavity 23 and leaving the limit channel 61.

[0075] In some embodiments of the present application, the limit frame 60 also includes a second limit column 65, which is located in the limit channel 61 and is connected to at least one of the first limit plate 62 and the second limit plate 63. The first part 51 bypasses the second limit column 65 on the side of the second limit column 65 away from the accommodating cavity 23 to avoid the second limit column 65. The second limit column 65 can be used to provide a limit for the first part 51 to prevent the first part 51 from moving toward the direction close to the accommodating cavity 23 and leaving the limit channel 61.

[0076] It should be noted that only one of the first limiting post 64 and the second limiting post 65 can be provided, or both the first limiting post 64 and the second limiting post 65 can be provided. The first limiting post 64 and the second limiting post 65 are arranged at intervals along the extending direction of the limiting channel 61. The first part 51 can be clamped between the first limiting post 64 and the second limiting post 65, and the first part 51 can be limited from two directions (the direction close to and away from the accommodating cavity 23) at the same time, preventing the first part 51 from moving away from the limiting channel 61 in the direction close to the accommodating cavity 23, and the first part 51 can be kept in a tensioned state to prevent the first part 51 from winding around the adapter 40.

[0077] In some embodiments, both the first limiting post 64 and the second limiting post 65 can be rotatable rollers, so that the relative friction between the first limiting post 64 and the second limiting post 65 and the first part 51 is rolling friction, thereby reducing the friction force between the first limiting post 64 and the second limiting post 65 and the first part 51.

[0078] In some embodiments, the first limiting post 64 can be arranged at the end of the limiting channel 61, and the first limiting post 64 can be arranged at both ends of the limiting channel 61; the second limiting post 65 can be arranged in the middle area of the limiting channel 61, and one or more second limiting posts 65 can be provided.

[0079] Continue to refer to Figures 4 to 6 As shown, in some embodiments, the limiting frame 60 is arranged at an interval from the outer side surface of the box body 20, that is, all parts of the limiting frame 60 are not in contact with the outer side surface of the box body 20, preventing the limiting frame 60 from generating debris due to friction with the box body 20 during movement.

[0080] In some embodiments, the sealing member 50 is an elastic sealing member, so that during the process of the adapter 40 moving along the first direction XX, when the connecting portion 43 of the adapter 40 pushes open a part of the sealing member 50 to form the first part 51, each part of the sealing member 50 can be kept in a tensioned state to prevent the sealing member 50 from winding around the adapter 40. And when the adapter 40 moves from the first position to the second position along the first direction XX, the first part 51 formed by the adapter 40 at the first position will move and reset in the direction of the accommodating cavity 23 under the action of elastic force to close the opening 24. Thus, during the process of the adapter 40 moving along the first direction XX, other parts of the sealing member 50 except the first part 51 can always keep the state of closing the opening 24, and the probability of debris in the accommodating cavity 23 being discharged from the opening 24 can be reduced.

[0081] Furthermore, the seal 50 is an elastic steel strip. The seal 50 can be formed of alloy steel such as chrome-nickel alloy, titanium alloy, copper-based alloy, etc. that have sufficient strength and elasticity. This can reduce the wear of the seal 50 by the limit frame 60 when the adapter 40 moves, improve the service life of the seal 50, and reduce the debris generated when the seal 50 rubs against the limit frame 60.

[0082] In some embodiments, the seal 50 is separably in contact with the bottom side surface of the receiving cavity 23. It can be understood that the bottom side surface of the receiving cavity 23 is the inner side surface of the bottom plate 21. The seal 50 is in contact with the bottom side surface of the receiving cavity 23 and can be separated from the bottom side surface of the receiving cavity 23, which can prevent the debris in the receiving cavity 23 from being discharged between the seal 50 and the bottom side surface of the receiving cavity 23. At the same time, it is convenient for the adapter 40 to push out a part of the seal 50 to form the first part 51 when moving in the first direction XX.

[0083] In some embodiments, both the connecting end 31 and the movable end 32 of the drag chain 30 are spaced from the inner side surface of the receiving cavity 23, which can prevent the movable end 32 of the drag chain 30 from rubbing against the box body 20 during the movement process. And since both ends (the connecting end 31 and the movable end 32) of the drag chain 30 are spaced from the inner side surface of the receiving cavity 23, the part of the drag chain 30 between its two ends can also be spaced from the inner side surface of the receiving cavity 23, thereby reducing or even eliminating the friction between the drag chain 30 and the box body 20 during the movement process.

[0084] Specifically, the drag chain mechanism 10 further includes a supporting member 70 (such as Figure 1 ), the supporting member 70 is located in the receiving cavity 23 and is connected to the box body 20. The connecting end 31 is connected to the supporting member 70 so that the connecting end 31 is spaced from the inner side surface of the receiving cavity 23. The connection between the connecting end 31 and the box body 20 can be realized through the supporting member 70, and the connecting end 31 is supported and connected, so that the connecting end 31 can be suspended, so that the connecting end 31 can be spaced from the inner side surface of the receiving cavity 23.

[0085] In some embodiments, the movable end 32 is connected to the side of the first end portion 41 close to the connecting end 31, so that during the movement of the adapter 40 in the first direction XX, the movable end 32 is always located on the side of the first end portion 41 close to the connecting end 31, and the overlapping portion of the movable end 32 and the first part 51 is less, which can prevent the debris in the receiving cavity 23 from being discharged through the gap formed by the formation of the first part 51 during the movement of the movable end 32.

[0086] In some embodiments, a wear-resistant layer is provided on the bottom side of the accommodation cavity 23. The wear-resistant layer can separate the bottom plate 21 from the drag chain 30, preventing the drag chain 30 from sagging under the action of gravity and rubbing against the bottom plate 21, which can extend the service life of the bottom plate 21. Among them, the wear-resistant layer can be formed by spraying, attaching or other means, and the wear-resistant layer can be a metal matrix composite layer, a metal matrix nano-layer, a metal matrix ceramic layer or other wear-resistant materials.

[0087] In some embodiments, the top side of the box body 20 is provided with an open mouth 25 communicating with the accommodation cavity 23, which can reduce the weight of the box body 20 and facilitate the hanging installation of the box body 20 at positions such as the ceiling. At the same time, devices such as the drag chain 30 can also be installed in the accommodation cavity 23 through the open mouth 25, making the installation of devices such as the drag chain 30 more convenient.

[0088] In a second aspect, based on the above drag chain 30 structure, the present application further provides a medical device, such as Figure 7 As shown, the medical device includes a device body, a movable device 81, and a drag chain mechanism 10 according to any one of the above embodiments. The device body is connected to the movable device 81, and the movable device 81 is connected to the movable end 32 of the drag chain mechanism 10 for driving the device body to move.

[0089] Among them, the device body can be an angiography device body. In other embodiments, the device body can also be a gastrointestinal camera body, a color Doppler scanner body or other device bodies.

[0090] In some embodiments, the drag chain 30 structure can be hung on the ceiling for use, and a slide rail 82 extending along the first direction XX is provided on the ceiling to provide support and guidance for the movable device 81.

[0091] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
