[0047] like Figure 1 As shown, the medical bracket device provided by the utility model includes: an adjusting rod component 1, a fixed rod component 2 and a locking device 3, the adjusting rod component 1 includes a first adjusting rod 11 and a second adjusting rod 12, the locking device 3 includes a first locking device 31 and a second locking device 32, the first adjusting rod 11 is connected to the fixed rod component 2 through the first locking device 31, the second adjusting rod 12 is connected to the first adjusting rod 11 through the second locking device 32, the second adjusting rod 12 is provided with a bellows 4 and a U-shaped block 5, the fixed rod component 2 includes a cylinder 21, a sliding block 22 and a connecting rod 23, and the first locking device 31 and the second locking device 32 have the same structural arrangement.
[0048] In order to prevent the medical stent from loosening after being locked, Figure 2 As shown, the locking method of the locking device 3 is hinged, and the locking device 3 includes a first curved pipe 311, a second curved pipe 312, a connecting shaft 313, an elastic washer 314, a ring 315, a handle 316 and a gasket 317. Figure 3As shown, the connecting shaft 313 includes a base 3131, a cylindrical portion 3132, a special-shaped portion 3133 and a threaded portion 3134. At the same time, a first special-shaped through hole 3111 is provided on the first curved pipe 311, and the shape and size of the first special-shaped through hole 3111 are adapted to the special-shaped portion 3133 of the connecting shaft 313. Through the threaded connection between the connecting shaft 313 and the handle 316, the first curved pipe 311 and the second curved pipe 312 are clamped and fixed, and the pre-tightening force generated by adding the elastic gasket 314 is conducive to preventing the pipeline from being pressed down and causing fracture and deformation, thereby protecting the life safety of the patient.
[0049] In one embodiment, the special-shaped portion 3133 is a rectangular structure or a hexagonal structure.
[0050] like Figure 4 , Figure 5 As shown, a first groove 3112 is provided on the outer surface of the first curved pipe 311 . In order to allow the base 3131 to rotate in the first groove 3112 , the shape and size of the first groove 3112 are adapted to the base 3131 for positioning the connecting shaft 313 .
[0051] In this embodiment, a second groove 3113 is provided on the inner surface of the first curved pipe 311 for placing the elastic gasket 314. Figure 6 As shown, the elastic washer 314 is wavy, and at least two wavy protrusions 3141 are provided on the elastic washer 314. In order to make the elastic force extrusion uniform and facilitate manufacturing, three wavy protrusions 3141 are provided on the elastic washer 314.
[0052] In this embodiment, if Figure 7a , 7b As shown, a first boss 3151 is arranged on the first surface of the ring 315, so that the first surface of the ring 315 and the first groove 3112 form a accommodating space for accommodating the elastic gasket 314, and a second boss 3152 is arranged on the second surface of the ring 315, and the second boss 3152 can be embedded in the second groove 3113 of the second bend pipe 312 to form a limiting structure to prevent the locking device 3 from shifting during rotation.
[0053] In this embodiment, a second special-shaped through hole 3121 is provided on the second bend pipe 312, and the shape and size are adapted to the special-shaped portion 3133 of the connecting shaft 313. In order to reduce the number of assembly parts, the first bend pipe 311 and the second bend pipe 312 can be designed as the same bend pipe, and the bend pipe can be made of metal or plastic, in particular, stainless steel or nylon. Furthermore, in order to reduce the friction loss between the handle 316 and the bend pipe, a gasket 317 can be set on the outside of the bend pipe.
[0054] In one embodiment, the shape of the gasket 317 is matched with the first groove 421 of the second elbow 42 .
[0055] like Figure 8 As shown, when assembling the locking device 3, the two elbows 311 and 312 are assembled in a mirror image, the connecting shaft 313 is inserted from the outside of the first elbow 311, and the elastic gasket 314 and the ring 315 are placed in sequence, and then the second elbow 312 is placed, and the threaded part of the connecting shaft 313 is inserted, and then the gasket 317 is inserted, and finally the handle 316 is screwed into the threaded part 3134 of the connecting shaft 313 to the appropriate position. When the first elbow 311 and the second elbow 312 rotate relative to each other and squeeze each other, the ring 315 transmits the pressure to the elastic gasket 314, and the elastic gasket 314 is elastically deformed under the action of pressure to its working height. The elastic gasket 314 will generate a continuous elastic force, so that the threaded connection pair of the connecting shaft 313 and the handle 316 continues to maintain a friction force, generating a resistance torque, preventing the handle from loosening, and adjusting the preload force.
[0056] In this embodiment, set screws 310 are provided on the cylindrical sides of both ends of the first curved tube 311 and the second curved tube 312, and the fixing rod component 2 and the adjusting rod component 1 are inserted into the corresponding positions and then locked and fixed.
[0057] In another embodiment, in order to arrange the pipelines more reasonably, one or more pipeline receiving structures 6 may be fixedly provided on the adjusting rod component 1, and the pipeline receiving structures 6 may be spring clips, hooks, etc.
[0058] In another embodiment, in order to make the medical bracket suitable for medical auxiliary equipment such as a trolley, and the medical bracket can rotate freely, the utility model is provided with a fixing structure suitable for a table hole, a set screw 310 is provided in the middle of the sliding block 22, the front end of the cylinder 21 passes through the sliding block 22 and is connected to the connecting rod 23 by interference fitting, fixed with the set screw 310, and finally the bottom nut is rotated to clamp. The fixed position of the medical bracket of this design is not limited to the edge of the table, and can be set at any position on the surface according to requirements. Secondly, after the nut is tightened, press the sliding block 22, and the entire medical bracket can achieve 360° free rotation, which is more convenient.
[0059] The utility model provides an elastic washer 314 and a circular ring 315 in the locking device 3. When the locking device 3 is tightened and fixed, the two bent pipes squeeze each other, and the circular ring 315 transmits the pressure to the elastic washer 314. The elastic washer 314 is elastically deformed under the pressure to its working height. The elastic washer 314 generates a continuous elastic force, so that the threaded connection pair of the connecting shaft 313 and the handle 316 continuously maintains a friction force, generating a resistance torque. This design can prevent the handle from loosening and adjust the preload force.
[0060] The cylinder 21 and the connecting rod 23 of the utility model are interference connected, the sliding block 22 passes through the cylinder 21 and is placed on the table top, and the bottom nut is rotated and clamped, so that the cylinder 21 and the connecting rod 23 rotate synchronously, and the sliding block 22 and the nut rotate synchronously after being tightened. When the medical bracket needs to be rotated, the sliding block 22 is pressed to make the connecting rod 23 and the cylinder 21 rotate relative to it, so that the angle can be freely adjusted.
[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it.
