[0031] The present invention will be described in detail below through embodiments.

[0032] Examples

[0033] like Figure 1 The present invention provides a semi-automatic testing chamber for housing nucleic acid testing kits, including a chamber frame 1, a lifting device 2, a chamber door 3, and a locking device 4, specifically configured as follows:

[0034] Combination Figures 2-4As shown, the detection chamber is formed in the rack 1 for horizontally pushing the nucleic acid reaction box 5. The lifting device 2 comprises a lifting intermediate plate 21 and a channel valve rotating mechanism 22. The lifting intermediate plate 21 is horizontally installed in the rack 1. Two first sliding grooves 23 are formed on the upper plate surface of the lifting intermediate plate 21 in the direction of horizontally pushing the nucleic acid reaction box 5. The channel valve rotating mechanism 22 is installed on the lifting intermediate plate 21 between the two first sliding grooves 23. The middle part of the door surface on the inner side of the door 3 is connected with a loading table 31 for placing the nucleic acid reaction box 5. Two slide rails 32 are respectively arranged on the two sides of the loading table 31 and are horizontally fixed on the door 3. The slide rails 32 are slidingly connected in the first sliding grooves 23, and the two slide rails 32 correspond to the two first sliding grooves 23. A locking block 33 is arranged on one side of the loading table 31 and is connected to the door 3. The locking device 4 is installed on the side wall of the rack 1 and comprises a speed reducer 41 and an eccentric bearing 42. The eccentric bearing 42 is connected to the speed reducer 41 by horizontal rotation, and a second sliding groove 34 is formed on the locking block 33 to facilitate the horizontal rotation of the eccentric bearing 42 into the second sliding groove 34 from one side of the locking block 33 after being driven. Through the arrangement of the structure, after the nucleic acid reaction box 5 is placed on the loading table 31, the door 3 is only needed to be manually pushed into the rack 1, and the door 3 will enter the rack 1 along the slide rails 32. At this time, the locking device 4 is driven to close the door 3 by the cooperation of the eccentric bearing 42 and the locking block 33 on the door 3 driven by the speed reducer 41, so as to realize the automatic sealing of the nucleic acid reaction box 5 in the reaction chamber when the door 3 is closed.

[0035] As described above, the rack 1 is a box structure. The detection chamber is formed on the front wall of the rack 1 for horizontally pushing the door 3 into the door docking interface. The base is fixed on the inner side of the slide rail 32 and comprises two oppositely arranged seat bodies 35. The detection chamber is formed on the side wall of the rack 1 for installing the door driving docking interface of the locking device 4.

[0036] Further, the locking device 4 further comprises a driving frame 43 and an eccentric wheel 44. The driving frame 43 is installed in the door driving interface, the reduction motor 41 is installed on the driving frame 43, and the output end of the reduction motor 41 is vertically downward. The eccentric wheel 44 is connected with the output end of the reduction motor 41 in an eccentric manner. A vertically arranged eccentric shaft is fixed in the wheel hole of the eccentric wheel 44, and the eccentric bearing 42 is located below the eccentric wheel 44 and is sleeved on the eccentric shaft. Through the arrangement of the structure, when the nucleic acid reaction box 5 is pushed into the warehouse body rack 1, the locking block 33 of the warehouse door 3 is just moved to one side of the eccentric bearing 42, at this time, the eccentric wheel 44 is driven to rotate eccentrically by the reduction motor 41, thereby driving the eccentric bearing 42 to rotate around the output end of the reduction motor 41 in the horizontal direction, and rotating into the second sliding groove 34 on the locking block 33, thereby performing the automatic closing and locking action of the warehouse door 3. Similarly, the eccentric bearing 42 is driven to rotate reversely by the reduction motor 41, so that the eccentric bearing 42 rotates out of the second sliding groove 34, thereby realizing the automatic unlocking of the warehouse door 3.

[0037] Further, the sliding block 24 is fixed in the first sliding groove 23, and the sliding block 24 is in sliding connection with the sliding rail 32. The limit switch 25 is installed on the lifting intermediate plate 21 at the end of the first sliding groove 23, and the limit trigger piece 36 which is in linkage with the limit switch is fixed on the base body 35 of the base, the limit trigger piece 36 is preferably a photoelectric sensing piece, and the limit switch 25 is electrically connected with the reduction motor 41. Through the arrangement of the structure, when the warehouse door 3 enters the warehouse body rack 1 along the sliding rail 32, the limit trigger piece 36 reaches the limit switch 25 of the lifting device 2, and the locking device 4 automatically performs the closing and locking action of the warehouse door 3, thereby realizing that the nucleic acid reaction box 5 is automatically put into and sealed in the warehouse body rack 1 when the warehouse door 3 is closed.

[0038] Preferably, the limit block 37 for abutting against the warehouse body rack 1 is fixed at the end of the sliding rail 32. The movement of the sliding rail 32 is stroke-limited by the limit block 37.

[0039] Further, in combination with Figure 3 and Figure 5As shown, the lock block 33 is arranged perpendicularly to the bin door 3, and the end of the lock block 33 close to the bin door 3 is connected to the inner side of the door face of the bin door 3 through a rotating shaft, so that the rotating direction of the lock block 33 is perpendicular to the bin door 3. The end of the lock block 33 close to the bin door 3 is formed with a recessed step groove at the bottom, and the first spring 38 perpendicular to the bin door 3 is embedded in the step groove. One end of the first spring 38 is connected to the inner side of the door face of the bin door 3, and the other end of the first spring 38 is connected to the inner wall of the step groove. The first spring 38 is supported at the bottom of the lock block 33, so as to ensure that the lock block 33 always remains horizontal and does not rotate in the normal state. An unlocking hole 39 is formed above the lock block 33 on the bin door 3. Through the arrangement of the structure, when the locking device 4 fails, the long rod device can be inserted into the bin body rack 1 through the unlocking hole 39, and the lock block 33 is rotated downward to separate the lock block 33 from the eccentric bearing 42 of the locking device 4, so as to realize the manual unlocking of the bin door 3. Similarly, after the long rod device is withdrawn, the lock block 33 can be restored to the horizontal state under the action of the first spring 38.

[0040] Further, the loading table 31 is slidingly connected to the base. Limiting blocks 6 are arranged on both sides of the loading table 31, and a connecting column perpendicular to the bin door 3 is arranged between the limiting blocks 6 and the bin door 3. One end of the connecting column is fixedly connected to the inner side of the door face of the bin door 3, and the other end of the connecting column 3 is fixedly connected to the limiting blocks 6. The side wall of the loading table 31 is formed with a limiting abutting portion for buckling the limiting blocks 6, so that a limiting interval for the sliding of the loading table 31 in the horizontal pushing direction of the nucleic acid reaction box 5 is formed between the limiting blocks 6 and the bin door 3. A plurality of second springs 7 are arranged between the bin door 3 and the loading table 31. One end of the second spring 7 is fixedly connected to the inner side of the door face of the bin door 3, and the other end of the second spring 7 is connected to the loading table 31. Through the arrangement of the structure, the loading table 31 can slide in the limiting interval in the front and back direction of the bin door 3, so that in the entering process of the bin door 3, the loading table 31 reaches the position with the nucleic acid reaction box 5, and after the bin door 3 is locked by the locking device 4, when the loading table 31 contacts with the rear wall of the bin body rack 1, the bin door 3 can continue to push into the bin body rack 1 under the action of the second spring 7, so as to facilitate the lifting of the channel valve rotating mechanism 22 to the position. Preferably, a plurality of limiting blocks 6 are arranged on both sides of the loading table 31 in the vertical direction.

[0041] As described above, looking back Figure 2The middle part of the lifting middle plate 21 is provided with a through hole in the vertical direction, and the channel valve rotating mechanism 22 is installed in the through hole and comprises a rotating shaft 221, a rotating head 222 and a lifting block 223.

The rotating head 222 is located above the lifting middle plate 21 and is sleeved on the rotating shaft 221 in a rotatable and up-and-down sliding manner. The middle part of the bottom surface of the rotating head 222 is provided with a sliding hole for the top end of the rotating shaft 221 to slide from bottom to top. A long key groove is formed in the vertical direction on the rod wall near the top end of the rotating shaft 221. A fixed key groove with the same width as the long key groove is formed on the inner wall of the sliding hole at a position corresponding to the long key groove, and a flat key is arranged in the long key groove and the fixed key groove to enable the rotating head 222 to slide up and down on the rotating shaft 221 while the rotating shaft 221 is driven to rotate and drive the rotating head 222 to rotate synchronously.

[0042] The lifting block 223 has an annular structure sleeved on the rotating head 222. An upper lifting guide wheel 225 is connected to the outer wall of each side of the lifting block 223, and an upper lifting guide groove is formed in the inner side wall of the seat body 35. The upper lifting guide groove has a downward inclined groove structure in the horizontal pushing direction of the nucleic acid reaction box 5, and the rear end of the upper lifting guide groove is provided with an opening for the upper lifting guide wheel 225 to slide into the upper lifting guide groove. The rotating head 222 is used to connect the bottom of the nucleic acid reaction box 5 after the nucleic acid reaction box 5 is horizontally pushed into the detection chamber. Through the arrangement of the structure, the clamping and lifting linkage of the nucleic acid reaction box 5 on the semi-automatic detection chamber of the present application is realized, so as to facilitate the subsequent nucleic acid reaction detection, and the chamber body structure of the semi-automatic detection chamber of the present application is small in size and high in function.

The upper positioning mechanism 8 and the side positioning mechanism 9 are both conventional positioning mechanisms in the existing nucleic acid reaction detection chamber.

[0045] The semi-automatic detection bin for the nucleic acid detection box of the application is used for putting the nucleic acid reaction box 5 into the loading table 31, and then the bin door 3 is gently pushed into the bin body frame 1 by hand, so that the bin door 3 can enter the bin body frame 1 along the slide rail 32; when the limiting trigger piece 36 reaches the limiting switch 25 of the lifting device 2, the locking device 4 automatically performs the closing and locking action of the bin door 3; after the loading table 32 contacts with the rear wall of the bin body 1 under the action of the spring 36, the bin door 3 can continue to advance and push the channel valve rotating mechanism 22 to be lifted into place, so that the rotating head 222 is lifted and clamped into the valve boss at the bottom of the nucleic acid reaction box 5, thereby facilitating the rotating operation.
