[0021] like Figure 1-4 As shown, a quick-release low-volatile silicone plug cover for a reagent bottle comprises a cover body 1 and a plug body 2. A pin hole 3 is provided in the center of the cover body 1 and passes through the front and back sides of the cover body 1. The cover body 1 has at least two notches 4 in an equidistant circular array around the pin hole 3. One end of the notch 4 is connected to the pin hole 3, and the other end is between the pin hole 3 and the edge of the cover body 1. The center of the pin hole 3 is on the length line of the notch 4. The notch 4 passes through the front and back sides of the cover body 1. The plug body 2 comprises a plug rod 6, a plug handle 7 and a plug head 5 cooperating with the pin hole 3. The plug head 5 is radially provided with a plug rod 6 cooperating with the notch 4, and the end face of the plug head 5 is axially provided with a plug handle 7.

[0022] In this embodiment, the cover body 1 is used to cover the opening of the reagent bottle (not shown in the figure), wherein the plug body 2 and the cover body 1 are both made of silicone, and the pin hole 3 is set on the cover body 1. The diameter of the pin hole 3 is about 2.4 mm, which is just enough to allow the needle to be inserted, and at the same time, the outer circumference of the needle will not touch the inner wall of the pin hole 3 during the insertion and removal of the needle. The cooperation between the notch 4 and the plug rod 6 is to enable the notch 4 to clamp the plug rod 6 after the plug body 2 is inserted into the pin hole 3, thereby preventing the plug body 2 from falling off from the pin hole 3. The plug handle 7 is set to facilitate the staff to hold the plug handle 7 to pull out the plug body 2 from the pin hole 3 when it is necessary to pull out the plug body 2. Since the pin hole 3 is relatively small, the volatilization of the reagent in the reagent bottle can be reduced during the reagent test.

[0023] As a preferred embodiment, the cover body 1 is provided with four notches 4. By providing four notches 4 and cooperating with four plug rods 2, the contact surface between the pin hole 3 and the plug body 2 is increased, so that the plug body 2 can be prevented from falling off from the pin hole 3.

[0024] As a preferred embodiment, the length of the plug head 5 is greater than the length of the pin hole 3, and the thickness of the plug rod 6 is greater than the thickness of the cover body 1. In this way, the pin hole 3 and the notch 4 can be completely filled.

[0025] There are two ways to set the plug body 2.

[0026] The first design method: Figure 4 As shown, the diameters at both ends of the plug 5 are larger than the diameter of the middle section, the diameter of the pin hole 3 is equal to the diameter of the middle section of the plug 5, and a groove 8 is provided on all surfaces of the plug rod 6 parallel to the axis of the plug handle 7, and the groove 8 and the middle section of the plug 5 are on the same cross section of the plug 5. After such arrangement, the groove 8 on the plug body 2 can exert an axial clamping force to clamp the edge of the pin hole 3, thereby increasing the sealing performance in the reagent bottle after the plug body 2 is inserted into the pin hole 3.

[0027] The second design is that an auxiliary plug 9 is provided on the surface of the plug 5 facing away from the plug handle 7, the auxiliary plug 9 is coaxial with the plug 5, the auxiliary plug 9 and the plug 5 are connected by an elastic member, the diameter of the end of the plug 5 facing the auxiliary plug 9 is smaller than the end of the plug 5 facing away from the auxiliary plug 9, the diameter of the auxiliary plug 9 is larger than the diameter of the plug 5, a channel is coaxially penetrated through the center of the plug handle 7, a hard rod 10 is coaxially provided in the channel, one end of the hard rod 10 penetrates the plug 5 and is fixedly connected to the auxiliary plug 9, the other end of the hard rod 10 extends out of the plug handle 7, and a stopper 14 cooperating with the auxiliary plug 9 is fixedly provided on the side of the plug 5 facing the plug handle 7.

[0028] After such arrangement, before inserting the plug body 2 into the pin insertion hole 3, the user can first press the end of the hard rod 10 extending out of the plug handle 7 by hand, so that the hard rod 10 pushes the auxiliary plug 9 to move back to the plug head 5, so that the portion between the notch 4 and the pin insertion hole 3 on the cover body 1 is basically restored to the state where the circumferential surface of the plug head 5 contacts the inner side wall of the pin insertion hole 3 after the plug body 2 passes through the pin insertion hole 3, and then the user lets go, and then pulls the hard rod 10 out of the reagent bottle by hand, so that the auxiliary plug 9 is pushed toward the edge of the plug handle 7 to facilitate the notch 4 and the pin insertion hole 3, so that the circumferential surface of the plug head 5 is completely in contact with the inner side wall of the pin insertion hole 3, so that complete sealing is achieved. The stopper 14 works together with the auxiliary plug 9 on the plug head 5 to clamp the portion between two adjacent notches 4 facing the pin insertion hole 3. The setting of the elastic member 11 allows the user to release the hard rod 10 and not press the end thereof extending outside the plug handle 7 , and the hard rod 10 returns to the channel under the action of the elastic member, and the auxiliary plug 9 moves closer to the stopper 14 .

[0029] Preferably, as shown in Figure 3 , a cavity is provided on the surface of the plug head 5 facing away from the plug rod 6 , one end of the elastic member 11 is fixedly connected to the inner bottom wall of the cavity, and the other end of the elastic member 11 is fixedly connected to the auxiliary plug 9 .

[0030] As a preferred embodiment, an auxiliary rod 12 is provided on the surface of the plug rod 6 facing away from the plug handle 7, the shape of the side of the plug rod 6 facing away from the plug handle 7 is similar to the side of the plug rod 6 facing the outside of the cover body 1, the shape and size of the side of the plug rod 6 facing away from the plug handle 7 is smaller than the side of the plug rod 6 facing the plug handle 7, the shape and size of the side of the auxiliary rod 12 facing the plug handle 7 is greater than or equal to the shape and size of the side of the plug rod 6 facing away from the plug handle 7, the auxiliary rod 12 is fixedly connected to the auxiliary plug 9, and a baffle 15 cooperating with the auxiliary rod 12 is fixedly provided on the surface of the plug rod 6 facing the plug handle 7.

[0031] After such arrangement, the baffle 15 and the auxiliary rod 12 work together to clamp the edge of the slot 4, so that the upper and lower surfaces of the slot 4 are fully in contact with the baffle 15 and the auxiliary rod 12 respectively, thereby enhancing the sealing effect; at the same time, the baffle 15 and the auxiliary rod 12 jointly clamp the portion of the cover 1 located at the edge of the slot 4 to prevent the plug body 2 from falling off from the pin hole 3.

[0032] As a preferred embodiment, the end of the plug handle 7 facing away from the plug head 5 is provided with a soft rubber 13 that is tightly connected to the plug handle 7, and the end of the hard rod 10 extending outside the plug handle 7 is inside the soft rubber 13, and the hard rod 10 is fixedly connected to the soft rubber 13. By providing the soft rubber 13, the soft rubber 13 has an elastic effect and works together with the elastic member 11, so that the hard rod 10 is pulled back after the user pushes the hard rod 10 to the plug handle 7.
