DETAILED DESCRIPTION
[0024] The following will be combined with the attached embodiment of the present utility model Figure 1-5 , the technical solutions in the embodiments of the utility model are described in detail.
[0025] like Figure 1 As shown, a surgical anesthesia pipeline bracket includes a fixed plate 1, a groove is opened on the top of the fixed plate 1, and a storage groove for placing a suspension component 5 is opened on one side of the groove, a flap 2 is vertically arranged above the fixed plate 1, and both sides of the bottom of the flap 2 are fixedly connected with a rotating shaft 4, and the flap 2 is rotatably connected to one end of the groove of the fixed plate 1 through the rotating shafts 4 on both sides, an angle fixing plug-in 3 is horizontally arranged on one side of the fixed plate 1, and one end of the angle fixing plug-in 3 is fixedly connected to the rotating shaft 4, the suspension component 5 is arranged above the flap 2 and intersects with the flap 2, and the suspension component 5 is located above the angle fixing plug-in 33, a slide groove is opened at the back of the flap 2, and the chuck assembly 6 is horizontally slidably connected in the slide groove behind the flap 2.
[0026] like Figure 2-3 As shown, the suspension assembly 5 includes a first telescopic rod 51, a second telescopic rod 52, a third telescopic rod 53 and a hook 54. The suspension assembly 5 is arranged on one side of the flap 2 and is located above the angle fixing plug-in 33. One end of the first telescopic rod 51 is hinged to the top of the flap 2, and the other end of the first telescopic rod 51 is hinged to one end of the second telescopic rod 52, and one end of the third telescopic rod 53 is hinged to the other end of the second telescopic rod 52, and the hook 54 is rotatably connected to the other end of the third telescopic rod 53. The structures of the first telescopic rod 51, the second telescopic rod 52 and the third telescopic rod 53 are the same. Because one end of the first telescopic rod 51 is hinged to the flap 2, when the suspension assembly 5 is needed, the first telescopic rod 51 can be rotated upward with the hinge point of the first telescopic rod 51 and the flap 2 as the center. At this time, the first telescopic rod 51 and the second telescopic rod 52 are parallel to each other.
[0027] like Figure 2-3As shown in the figure, after the first telescopic rod 51 and the second telescopic rod 52 are rotated upward to the required height with the hinge point of the first telescopic rod 51 and the flap 2 as the center, the second telescopic rod 52 is rotated upward again to the required height with the hinge point of the second telescopic rod 52 and the first telescopic rod 51 as the center, the third telescopic rod 53 is rotated outwardly with the intersection of the third telescopic rod 53 and the second telescopic rod 52 as the center, and then the hook 54 is rotated again. After the suspension assembly 5 is fully opened, the tube of the ventilator can be placed. The road is hung on the hook 54 for fixation, and a storage groove is opened on one side of the suspension component 5 inside the groove of the fixed plate 1. Therefore, after the suspension component 5 is used, the first telescopic rod 51, the second telescopic rod 52 and the third telescopic rod 53 can be rotated in reverse. After the first telescopic rod, the second telescopic rod 52 and the third telescopic rod 53 are rotated to one side of the flap 2, the flap 2 can be rotated clockwise. When the flap 2 is placed in the groove of the fixed plate 1, the suspension component 5 will also be placed in the storage groove on one side of the groove.
[0028] like Figure 2-3 As shown, a slide groove is provided on the back of the flap 2, and the chuck assembly 6 is laterally slidably connected in the slide groove on the back of the flap 2. A plurality of limiting holes 22 are provided inside the slide groove on one side of the slider 64 of the chuck assembly 6. Catheter slots 21 are provided on both sides of the bottom of the flap 2, and the catheter slots 21 are located below the chuck assembly 6. When in use, the ventilator pipe and the like can be placed inside the catheter slot 21 for fixing. One end of the fixed plate 1 is fixedly connected with a socket 2. When moving, after the flap 2 is placed in the groove inside the fixed plate 1, the fixed plate 1 and the flap 2 are moved by holding the socket 2, and they can be fixed through the socket 2 after use.
[0029] like Figure 3-4 As shown, the angle fixing plug-in 3 includes an extension rod 31, a limit pin 32 and a second spring 33. The second spring 33 used is a tension spring, and the angle between the length direction of the extension rod 31 and the length direction of the flap 2 is 90 degrees. Because one end of the extension rod 31 is fixedly connected to one end of the rotating shaft 4, and the other end of the rotating shaft 4 is fixedly connected to the flap 2, even when the flap 2 rotates, the angle between the flap 2 and the extension rod 31 will always remain unchanged. At the same time, when the rotating shaft 4 is driven by the flap 2 to rotate, the extension rod 31 will rotate together with the rotating shaft 4 and follow the flap 2. A through hole is opened at the other end of the extension rod 31, and a limit pin 32 is arranged in the through hole. The limit pin 32 is sleeved with a second spring 33.
[0030] like Figure 3-4As shown, the second spring 33 is located in the middle position between the limit pin 32 and the extension rod 31, and one end of the second spring 33 is fixedly connected to the limit pin 32, and the other end of the second spring 33 is connected to the extension rod 31. When the extension rod 31 is driven to rotate by the rotating shaft 4, the limit pin 32 will rotate together with the extension rod 31, but because the limit pin 32 and the extension rod 31 are connected by the second spring 33, when the limit pin 32 rotates together with the extension rod 31, the limit pin 32 will not fall off the extension rod 31. The fixed plate 1 is provided with two sockets 11 at a position on one side of the extension rod 31, and the two sockets 11 are respectively located on one side of the fixed axis and below the fixed axis, and the angle between the two sockets 11 is also 90 degrees.
[0031] like Figure 3-4 As shown, when the flap 2 is opened, the angle between the length direction of the flap 2 and the length direction of the fixed plate 1 is 90 degrees, and the angle between the length direction of the extension rod 31 and the length direction of the flap 2 is also 90 degrees. Therefore, when the flap 2 is opened, the length direction of the extension rod 31 is the same as the length direction of the fixed plate 1. Therefore, after the flap 2 is fully opened, the limit pin 32 is fixed in the socket 11 on one side of the fixed shaft by the second spring 33 and under the action of the second spring 33, the limit pin 32 will not fall from the through hole of the extension rod 31. Therefore, at this time, the limit pin 32 can fix the position of the flap 2 through the extension rod 31 and the fixed shaft to prevent the flap 2 from falling suddenly during use.
[0032] like Figure 3-4 As shown, after the use of the flap 2, the limit pin 32 can be pulled out from the socket 11 on one side of the fixed shaft, and the flap 2 can be rotated to place the flap 2 in the groove of the fixed plate 1. Because one end of the second spring 33 is connected to the limit pin 32, when the limit pin 32 is pulled out from the socket 11, one end of the second spring 33 will move together with the limit pin 32, but because the other end of the second spring 33 is connected to the extension rod 31, when the limit pin 32 is pulled out, the second spring 33 will be stretched and stored. When the flap 2 is rotated 90 degrees clockwise and placed in the groove of the fixed plate 1, the extension plate will rotate 90 degrees clockwise together with the flap 2 driven by the fixed shaft.
[0033] like Figure 3-4As shown, at this time, the length direction of the extension plate is 90 degrees to the length direction of the fixed plate 1, and the limit pin 32 will also be driven by the extension rod 31 to rotate 90 degrees and move to the position of the socket 11 below the fixed axis. At this time, the limit pin 32 can be released after aligning the limit pin 32 with the socket 11 below the fixed axis. After the limit pin 32 is released, the second spring 33 will use the force accumulated when the limit pin 32 is pulled out to pull the limit pin 32 to reset. After being guided by the through hole at one end of the extension rod 31, the limit pin 32 will be pulled by the second spring 33 to reset to the through hole below the fixed axis. After the limit pin 32 is reset to the axis of the socket 11 below the fixed axis, the position of the flap 2 can be fixed by the extension rod 31 and the rotating shaft 4.
[0034] like Figure 5 As shown, the chuck assembly 6 includes a chuck 61, a slot 62, a guide rod 63, a slider 64, a fixing rod 65 and a first spring 66. The chuck 61 is slidably connected in a slide groove on the back of the flap 2. When in use, the height of the chuck 61 can be adjusted up and down in the slide groove on the back of the flap 2 as needed. A plurality of slots 62 for fixing handheld instruments are vertically arranged on the chuck 61, and the slots 62 are parallel to each other. Two guide rods 63 are both fixedly connected in a horizontal direction through the slider 64 to form a groove on one side of the inner part of the chuck 61. In the figure, the two guide rods 63 are parallel to each other and the two guide rods 63 are both sleeved with a first spring 66, and the first spring 66 is located at one end of the slider 64, and the other end of the slider 64 is transversely provided with two fixing rods 65, one end of the fixing rod 65 is fixedly connected to the slider 64, and the other end of the fixing rod 65 is arranged in the chuck 61 through a preset through hole on the chuck 61, so when the slider 64 is pushed by the spring and guided by the guide rod 63 to move transversely, the fixing rod 65 will move transversely together with the slider 64.
[0035] like Figure 5 As shown, when the chuck 61 needs to move up and down, it is only necessary to move the slider 64 horizontally by hand. When the slider 64 moves horizontally, the fixing rod 65 will be pulled out from the limiting hole 22 on one side of the slide groove of the flap 2. At this time, the height of the chuck 61 can be adjusted by hand. When the slider 64 moves horizontally, it will be guided by the guide rod 63, and the guide rod 63 is sleeved with a first spring 66. Therefore, when the slider 64 moves horizontally, it will squeeze the first spring 66 on the guide rod 63. The first spring 66 will accumulate force after being squeezed. Therefore, after adjusting the height of the chuck 61, it is only necessary to release the slider 64. The force accumulated by the first spring 66 when the slider 64 moves horizontally and is squeezed will immediately pop out the slider 64 for reset. When the slider 64 is reset, it will push the fixing rod 65 into the limiting hole 22 again to fix the height of the chuck 61 to prevent the chuck 61 from falling suddenly during use.
[0036] The movement process of this embodiment: when in use, after the limit pin 32 is pulled out from the socket 11 below the fixed shaft, the flap 2 can be rotated counterclockwise. After the flap 2 is taken out from the groove of the fixed plate 1, the limit pin 32 can be inserted into the groove on one side of the fixed shaft. At this time, the limit pin 32 can fix the position of the flap 2 through the extension rod 31 and the fixed shaft. After the limit pin 32 is inserted into the socket 11 on one side of the fixed shaft, the first extension rod 31 of the suspension assembly 5 can be rotated upward. After the first extension rod 31 is rotated upward to the desired height, the second extension rod 31 can be rotated upward again. After the second extension rod 31 is rotated to the desired height, the third extension rod 31 can be rotated forward to adjust the position of the hook 54.
[0037] After adjusting the position of the hook 54, the ventilator pipe and the like can be fixed on the hook 54, and then the slider 64 in the chuck 61 can be manually moved horizontally, and the fixing rod 65 can be pulled out of the limiting hole 22 through the slider 64. At this time, the height of the chuck 61 can be manually adjusted. After adjusting the height of the chuck 61, the slider 64 can be released, and the first spring 66 will pop out the slider 64 for reset. During the reset process, the slider 64 will push the fixing rod 65 into the limiting hole 22 again to fix the position of the chuck 61. After that, rotate the first telescopic rod 51, the second telescopic rod 52 and the third telescopic rod 53 of the suspension assembly 5 in the opposite direction. After the first telescopic rod 51, the second telescopic rod 52 and the third telescopic rod 53 are rotated to one side of the flap 2, the limit pin 32 can be pulled out from the socket 11 on one side of the fixed shaft, and then the flap 2 is rotated clockwise, the flap 2 is placed into the groove of the fixed plate 1 and ensure that the suspension assembly 5 is placed in the receiving groove on one side of the groove of the fixed plate 1, and then the limit pin 32 is placed into the socket 11 under the fixed shaft again to fix the position of the flap 2.
[0038] The above embodiments are only for illustrating the technical idea of the present utility model, and cannot be used to limit the protection scope of the present utility model. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present utility model shall fall within the protection scope of the present utility model.
