The present embodiment is a structure of a fluorescence quantitative PCR detection sample cup, and the specific structure is shown in fig. 1 and 2.
As shown in fig. 1 and 2, the sample cup structure comprises a cup body 10 and a cup cover 20. One end of the cup lid 20 is connected with the cup body 10 through a connecting plate 30, so that the cup lid 20 can be prevented from being lost. The other end of the cup cover 20 is a cover lifting sheet 201 for lifting the cup cover 20. The cup cover 20, the cup body 10 and the connecting plate 30 are integrally formed by injection molding, and the integral injection molding can improve the manufacturing efficiency and reduce the material types.
As shown in figures 1 and 2, a circular channel 11 is arranged in the cup body 10, and the inner diameter of the inner wall of the channel 11 is gradually reduced from the opening 111 of the channel 11 to the inner direction. The bottom surface 12 of the channel 11 is inclined. A cavity 14 for containing a sample is arranged below the channel 11, and the channel 11 is communicated with the cavity 14 through two flow channels 13.
As shown in fig. 1 and 2, the cap 20 has an elastic plug 202. The cup cover 20 is provided with a snap ring 21, and the inner wall of the opening 111 of the channel 11 is provided with an annular clamping groove 15. When the plug 202 is inserted into the channel 11 from the opening 111 of the channel 11, the snap ring 21 is snapped into the snap groove 15 to form a fixed position, so that the lid 20 cannot be easily separated from the channel 11 of the cup 10 to maintain the seal.
As shown in fig. 1 and 2, the plug body 202 includes a cup-shaped front plug 23 and an annular rear plug 22. The outer wall of the front plug 23 is tapered and the outer diameter of the outer wall of the open end of the front plug 23 is the largest. In fig. 2, the front plug 23 opens in the direction of the insertion channel 11. Further, the outer wall of the rear plug 22 is provided with an outwardly flared annular skirt 221. The skirt 221 forms an acute angle with the outer wall of the rear plug 22 towards the front plug 23. When the plug body 202 is inserted into the channel 11 from the opening 111 of the channel 11, the outer wall of the front plug 23 forms an interference compression seal with the inner wall of the channel 11, and the annular skirt 221 of the rear plug 22 forms an interference compression seal with the inner wall of the channel 11. At this time, the snap ring 21 is fixed in the clamping groove 15, the plug body 202 is fixed in the channel 11, two layers of sealing are always kept, and the sealing is not easy to lose efficacy. And because the diameter of the inner wall of the channel 11 is gradually reduced, the more the front plug 23 and the rear plug 22 are deeply arranged in the channel 11, the more the mutual pressing force is improved, and the sealing performance is stronger.
The sample cup structure of this embodiment forms double seal structure through setting up preceding stopper 23 and back stopper 22 and the passageway 11 of cup 10 at bowl cover 20, consequently when meetting high temperature, liquid or gas leakage can not appear, and then can not pollute the external world, has reduced the probability of occurence of failure, has improved the security.
The technical contents of the present invention are further illustrated by the examples only for the convenience of the reader, but the embodiments of the present invention are not limited thereto, and any technical extension or re-creation based on the present invention is protected by the present invention. The protection scope of the utility model is subject to the claims.
