Detailed Description
The present application is described in further detail below with reference to fig. 1.
The embodiment of the application discloses gas chromatography detects with collecting mechanism. As shown in figure 1, a gas chromatography detects with collecting mechanism, including fixed plate 1 and spacing subassembly 2, is connected with into appearance dish 3 through vertical axis 31 rotation on the fixed plate 1, and a plurality of grooves 32 of establishing of inlaying have been seted up to the upper surface circumference of advancing appearance dish 3, and each inlays to establish and all slides in the groove 32 and inlays and be equipped with test tube 33. In the sample feeding process, a tester places a test tube 33 in each embedding groove 32; after one of them test tube 33 advanced kind and accomplished, rotatory sample dish 3 makes another test tube 33 rotatory to the injector under, can advance kind once more, need not the testing personnel and changes test tube 33 one by one, has improved kind efficiency.
Spacing subassembly 2 includes fixes mounting panel 22 on fixed plate 1 through riser 21, and mounting panel 22 is located the top of advancing appearance dish 3, and is equipped with joint spare and elastic component on the mounting panel 22, and the joint spare is joint hemisphere 23, and the elastic component is spring 24, and spring 24's one end fixed connection is in joint hemisphere 23, and spring 24's other end fixed connection is in mounting panel 22. In the rotation process of the sample injection disc 3, one of the test tubes 33 will rotate to abut against the hemispherical surface of the clamping hemisphere 23 and urge the clamping hemisphere 23 to rise, and at this time, the spring 24 will be compressed; when the test tube 33 rotates to the position right below the clamping hemisphere 23, the spring 24 will return to the natural state and urge the clamping hemisphere 23 to descend and be clamped in the test tube 33, so that the stability of the sample feeding tray 3 and all the test tubes 33 is ensured.
The diameter of clamping hemisphere 23 is larger than the inner diameter of test tube 33, so clamping hemisphere 23 will not be able to be completely clamped into test tube 33. After the test tube 33 is fed with the sample, the sample feeding disc 3 is rotated, and the inner wall of the test tube 33 clamped by the clamping hemisphere 23 is rotationally abutted to the hemisphere surface of the clamping hemisphere 23 and promotes the clamping hemisphere 23 to ascend, so that the clamping hemisphere 23 can be conveniently separated from the test tube 33 and clamped into another test tube 33.
The lower surface of mounting panel 22 is seted up and is run through in the spacing groove 221 of mounting panel 22 upper surface, and sliding fit is equipped with gag lever post 25 in the spacing groove 221, and gag lever post 25's lower extreme fixed connection is in joint hemisphere 23, and the upper end of gag lever post 25 is worn out from the spacing groove 221. In the lifting process of the clamping hemisphere 23, the limiting rod 25 slides in the limiting groove 221, so that the clamping hemisphere 23 clamped in the test tube 33 is not easy to shake, and the stability of the sample feeding disc 3 and all the test tubes 33 is improved; the upper end of pulling gag lever post 25 can make joint hemisphere 23 break away from test tube 33 in, makes things convenient for sample plate 3 to drive test tube 33 rotatory.
Go into on the lateral wall of sample tray 3 circumference and seted up a plurality of intercommunications in the corresponding spout 34 of establishing groove 32 that inlays, be fixed with a spacing ring 4 through stand 41 on the fixed plate 1, spacing ring 4 is located between sample tray 3 and the mounting panel 22, is equipped with the breach 42 that supplies test tube 33 business turn over on the spacing ring 4, and test tube 33 is located the inboard of spacing ring 4. The test tube 33 is slid horizontally by the inspector, so that the test tube 33 can be forced to enter and exit the embedding slot 32 through the notch 42 and the sliding slot 34, and the length of the test tube 33 is usually 5-10 times of the diameter of the test tube, so that the time spent by the test tube 33 to enter and exit the embedding slot 32 through the notch 42 and the sliding slot 34 is less than the time spent by the test tube 33 to enter and exit the embedding slot 32 by sliding vertically, and the test tube 33 can be replaced more quickly.
Seted up a plurality of hemisphere grooves 43 of crossing on the inner wall of spacing ring 4, the piece of propping inlays the ball 44 of establishing in passing hemisphere groove 43 for rolling, and ball 44 is contradicted in the outer wall of test tube 33, and the inner wall of spacing ring 4 is the interval with the outer wall of test tube 33 and sets up. At the in-process that advances kind dish 3 and drive test tube 33 rotation, the inner wall of spacing ring 4 will not contact with the outer wall of test tube 33, and ball 44 will roll and contradict in the outer wall of test tube 33 to make things convenient for the rotation of test tube 33, and reduced the wearing and tearing of test tube 33 outer wall.
Clamping hemisphere 23 joint is in the test tube 33 that is located breach 42 department for test tube 33 of breach 42 department is difficult for falling because of rocking and breaks away from in inlaying groove 32, has avoided test tube 33 to fall and has broken. Inlay and to have seted up heavy groove 35 on the bottom cell wall of establishing groove 32, inlay and establish and will sink to heavy inslot 35 in inlaying the test tube 33 bottom of establishing in groove 32, so the testing personnel only with test tube 33 pull-up break away from in heavy groove 35 just can inlay test tube 33 along the horizontal direction roll-off and establish groove 32 and spout 34 to the stability of test tube 33 has been improved.
The implementation principle of the collecting mechanism for gas chromatography detection in the embodiment of the application is as follows: in the sample feeding process, a detector slides the test tube 33 horizontally through the notch 42 and the sliding groove 34 and places the test tube 33 into the embedding grooves 32, so that one test tube 33 is placed in each embedding groove 32; after one of them test tube 33 advanced kind and accomplished, rotatory sample dish 3 makes another test tube 33 rotatory to the injector under, can advance kind once more, need not the testing personnel and changes test tube 33 one by one, has improved kind efficiency.
In the rotation process of the sample injection disc 3, one of the test tubes 33 will rotate to abut against the hemispherical surface of the clamping hemisphere 23 and urge the clamping hemisphere 23 to rise, and at this time, the spring 24 will be compressed; when the test tube 33 rotates to the position right below the clamping hemisphere 23, the spring 24 will return to the natural state and urge the clamping hemisphere 23 to descend and be clamped in the test tube 33, so that the stability of the sample feeding tray 3 and all the test tubes 33 is ensured.
After the test tube 33 is fed with the sample, the sample feeding disc 3 is rotated, and the inner wall of the test tube 33 clamped by the clamping hemisphere 23 is rotationally abutted to the hemisphere surface of the clamping hemisphere 23 and promotes the clamping hemisphere 23 to ascend, so that the clamping hemisphere 23 can be conveniently separated from the test tube 33 and clamped into another test tube 33.
When the test tube 33 needs to be taken down, the tester pulls the upper end of the limiting rod 25 with one hand to make the clamping hemisphere 23 separate from the test tube 33 at the notch 42, pulls the test tube 33 at the notch 42 upwards with the other hand to separate from the sinking groove 35, and then slides the test tube 33 out of the notch 42 and the sliding groove 34 along the horizontal direction to finish taking out the test tube 33.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
