[0024] Reference Figure 1-6 , the utility model provides a positive pressure joint protective cover structure, including a positive pressure joint 1;
[0025] A connecting protection structure 2, wherein the connecting protection structure 2 includes a protective cover 21, and the inner surface of the protective cover 21 is threadedly connected to the outer surface of the upper end of the positive pressure joint 1;
[0026] The replacement disinfection structure 3 includes a return spring 31 , and the return spring 31 is inserted inside the inner upper end surface of the protective cover 21 .
[0027] Furthermore, the connection protection structure 2 also includes a limiting groove 22, and the outer surface of the limiting groove 22 is sleeved with a collar 23, the center of the outer surface of one end of the collar 23 is fixedly connected to a connecting rope 24, and the outer surface of one end of the connecting rope 24 is fixedly connected to a first semicircular ring 25, and one end of the first semicircular ring 25 is hingedly connected to a second semicircular ring 26, and the upper end of the outer surface of one side of the positive pressure joint 1 is fixedly connected to a ring base 27, according to Figure 1 and Figure 3 As shown, the size of the limiting groove 22 is matched with the size of the collar 23 , and when the protective cover 21 is rotated, the collar 23 will not rotate along with the protective cover 21 .
[0028] Furthermore, the outer surface of the upper end of the protective cover 21 is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are evenly distributed around the outer surface of the upper end of the protective cover 21. Figure 1 and Figure 3 As shown, the anti-slip grooves prevent the protective cover 21 from slipping when rotating.
[0029] Further, the first semicircular ring 25 and the second semicircular ring 26 are both set to be semicircular, and a snap-fit block is provided at the other end of the first semicircular ring 25, and a snap-fit groove is provided at the position corresponding to the snap-fit block on the first semicircular ring 25 on the inner surface of one end of the second semicircular ring 26, and the snap-fit block on the first semicircular ring 25 and the snap-fit groove on the second semicircular ring 26 are snap-fitted on the inner side of the annular base 27. Figure 3 and Figure 4 As shown, the first semicircular ring 25 and the second semicircular ring 26 are a circular ring when they are engaged, and are connected to the annular base 27. When opened, the connection protection structure 2 can be removed.
[0030] Further, the replacement disinfection structure 3 also includes a snap-fit hemisphere 32, and the snap-fit hemisphere 32 is fixedly connected to the outer surface of one end of the return spring 31, and a limit ring is provided at one end of the snap-fit hemisphere 32, and a disinfection pad 33 is inserted into the inner side of the protective cover 21. Figure 5 and Figure 6 As shown, the fiber ring on the locking hemisphere 32 prevents the locking hemisphere 32 from escaping from the interior of the protective cover 21. The other end of the locking hemisphere 32 is set to a semicircular shape. When the disinfection pad 33 is pushed against the outer surface of the locking hemisphere 32, the locking hemisphere 32 is displaced to compress the reset spring 31. When the lower edge of the top of the disinfection pad 33 exceeds the height of the locking hemisphere 32, due to the elasticity of the reset spring 31 itself, the locking hemisphere 32 is reset to lock and fix the disinfection pad 33.
[0031] Further, two sets of return springs 31 and engaging hemispheres 32 are provided, and the two sets of return springs 31 and engaging hemispheres 32 are symmetrically distributed at both ends of the inner surface of the protective cover 21. Figure 5 and Figure 6 As shown, the two sets of return springs 31 and the locking hemispheres 32 cooperate to lock and fix the position of the disinfection pad 33 to prevent the disinfection pad 33 from falling off from the inside of the protective cover 21.
[0032] Working principle: First, insert the disinfection pad 33 into the protective cover 21, and the upper edge of the top of the disinfection pad 33 pushes against the clamping hemisphere 32 to move and squeeze the reset spring 31. Then, when the lower edge of the top of the disinfection pad 33 exceeds the height of the clamping hemisphere 32, due to the elasticity of the reset spring 31, the two groups of clamping hemispheres 32 reset and clamp the disinfection pad 33. Finally, the protective cover 21 is rotated and connected to the outer surface of the upper end of the positive pressure joint 1. When injecting medicine, the protective cover 21 is rotated and unscrewed, and then the ring 23, the connecting rope 24, and the first semicircular ring are used to connect the disinfection pad 33. 25. The connection between the second semicircular ring 26 and the annular base 27 connects the protective cover 21 to the outer surface of the positive pressure joint 1. When the connection protection structure 2 is damaged, the engagement between the first semicircular ring 25 and the second semicircular ring 26 can be opened, so that the first semicircular ring 25 and the second semicircular ring 26 are disconnected from the annular base 27. At this time, a new connection protection structure 2 is taken to engage the first semicircular ring 25 and the second semicircular ring 26 with the annular base 27 to connect them, thereby replacing the connection protection structure 2.
[0033] Before the protective cover 21 is screwed on after the injection is completed, the disinfection pad 33 is pulled out first, and a new disinfection pad 33 is inserted into the interior of the protective cover 21. First, the upper edge of the top of the disinfection pad 33 pushes against the locking hemisphere 32 to move and squeeze the reset spring 31. Then, when the lower edge of the top of the disinfection pad 33 exceeds the height of the locking hemisphere 32, due to the elasticity of the reset spring 31, the two groups of locking hemispheres 32 reset and lock the fixed disinfection pad 33. Finally, the protective cover 21 is screwed on, so that the disinfection pad 33 disinfects the upper end and inner wall of the positive pressure connector 1. The above is the entire working principle of the utility model.
