DETAILED DESCRIPTION

[0020] like Figures 1 to 8The test tube cover structure of the fully automatic digestion instrument shown is characterized in that: a test tube cover holder hook 2 is set at the top center of the test tube cover holder 1, and the test tube cover holder hook 2 can cooperate with the robotic arm to allow the test tube cover holder 1 to be raised and lowered, and a plurality of positioning seats 4 are set at the bottom of the test tube cover holder 1, and guide holes are set in the positioning seats 4, and guide fillets are set at the ends of the guide holes. A plurality of test tubes 7 are inserted into the test tube rack 3, and a plurality of positioning pins 5 are set at the top of the test tube rack 3. The position of the positioning pin 5 corresponds to the position of the positioning seat 4. The positioning pin 5 has a large taper and its top is an arc top structure. The positioning seat 4 is used for inserting and removing the positioning pin 5.

[0021] The test tube cover holder 1 is divided into two types, one of which is an independent type. The test tube cover holder 1 is used to place several independent test tube covers 6. A reflux groove 8 is set in the test tube cover 6 to collect the condensed acid liquid. The bottom of the test tube cover 6 is provided with an air hole 9 and a reflux hole 10. The air hole 9 is used to discharge the acid vapor generated in the test tube 7 during the test. The reflux hole 10 can return the acid liquid collected by the reflux groove 8 to the test tube 7. The bottom of the test tube cover 6 is provided with an arc-shaped bottom surface 12 for tightly covering the test tube 7. A conical limit 11 is provided at the port of the test tube cover 6 for limiting the jack of the test tube cover holder 1.

[0022] The other is an integrated type, in which the test tube cover bracket 1 and the test tube cover 6 are integrally formed. A rib 13 is provided around the top of the integrated test tube cover bracket 1 to prevent the condensed liquid from flowing elsewhere. A plurality of limiting grooves 14 are provided at the bottom of the integrated test tube cover bracket 1, and the limiting grooves 14 respectively correspond to the ports of the test tube 7.

[0023] In the embodiment, the test tube cover holder 1 is matched with and connected to the robot arm through the test tube cover holder hanging buckle 2, and the robot arm drives the test tube cover holder 1 to move toward the test tube rack 3. Since the position of the positioning seat 4 corresponds to the position of the positioning pin 5, the guide hole of the positioning seat 4 can be used for the positioning pin 5 to be inserted, so that the test tube cover 6 on the test tube cover holder 1 is tightly covered in the port of the test tube 7. The test tube cover holder 1 is divided into an independent type and an integrated type. The independent test tube cover holder 1 is used to place several independent test tube covers 6. The bottom of the test tube cover 6 is set to an arc-shaped bottom surface 12, which can be tightly covered with the test tube 7. A conical limit 11 is provided at the port, which can be limited by the jack of the test tube cover bracket 1. An air vent 9 and a reflux hole 10 are provided at the bottom of the test tube cover 6. The air vent 9 can discharge the acid vapor generated in the test tube 7. The reflux hole 10 can collect the condensed acid liquid in the reflux groove 8 and return it to the test tube 7. The integrated test tube cover bracket 1 can prevent the condensed liquid from flowing elsewhere through the retaining edges 13 provided around it, thereby avoiding contamination or corrosion of the instrument. The integrated test tube cover bracket 1 also has a plurality of limit grooves 14 provided at its bottom to play a limiting role, thereby preventing the test tube 7 from further moving.

[0024] The above description is only illustrative and not restrictive of the present invention. Those skilled in the art will understand that many modifications, changes or equivalents may be made without departing from the spirit and scope defined by the claims, but all of them will fall within the scope of protection of the present invention.
