[0026] Figure 1-Figure 3 The structure diagram of the first embodiment of the conical sample adding device for chemical detection according to the utility model is shown in FIG. Figure 1-Figure 3, a conical sample adding device for chemical detection according to this embodiment, the main body of which includes a sampling tube 100;

[0027] The sampling tube 100 is provided with a sliding groove 110, in which a slider 120 is slidably connected, and a locking wheel 130 and a limiting plate 140 are connected to the slider 120. A limiting hole 150 is provided at the end of the sampling tube 100, and a movable sleeve 160 is slidably connected in the limiting hole 150. A threaded rod 170 is threadedly connected in the movable sleeve 160. An adapter sleeve 171 and a rotating wheel 180 are distributed at both ends of the threaded rod 170. The adapter sleeve 171 is connected to a piston 172, and a threaded rod 170 is installed on the threaded rod 170. There is a limit rod 190. Specifically, the sliding groove 110 is located on the side wall of the sampling tube 100, and the two sliding grooves 110 are symmetrically arranged. Scales are arranged on both sides of the sliding groove 110. The sliding groove 110 is used to carry the slider 120 for sliding. The slider 120 is used to carry the locking wheel 130 and is fixedly connected with the limit plate 140. The locking wheel 130 is screwed with the slider 120 and penetrates the slider 120 to abut against the sampling tube 100. The locking wheel 130 is used to fix the limit plate 140 in the sliding groove 110.

[0028] A limit block 161 is arranged on the side wall of the movable sleeve 160. The limit blocks 161 are evenly distributed, and the limit blocks 161 are slidably connected with the limit hole 150. The limit rod 190 is located at the connection between the rotating wheel 180 and the threaded rod 170, and the horizontal height of the limit rod 190 is consistent with the limit plate 140. The limit hole 150 is used to carry the movable sleeve 160 to slide and limit the movable sleeve 160. The movable sleeve 160 is used to carry the threaded rod 170 for threaded connection. The threaded rod 170 is used to be rotatably connected with the adapter sleeve 171 and carry the rotating wheel 180. The adapter sleeve 171 is used to connect the threaded rod 170 and the piston 172. The piston 172 is driven by the threaded rod 170 to reduce and increase the pressure in the inner cavity of the sampling tube 100 to extract and extrude the sample. The rotating wheel 180 is used to facilitate pushing the threaded rod 170 and drive the threaded rod 170 to rotate.

[0029] One end of the sampling tube 100 is conical, and a sampling port is provided at the conical end, and the sampling port is used for the sample to enter and exit the sampling tube 100;

[0030] The locking wheel 130 provided on the slider 120 can fix the slider 120 in the sliding groove 110, and the sliding fixation drives the fixing of the limit plate 140 at the same time. When the sampling tube 100 is weighed, the threaded rod 170 is driven to move toward the inner cavity of the sampling tube 100 by pushing the rotating wheel 180 or rotating the rotating wheel 180. When the rotating wheel 180 is pushed or pulled, the movable sleeve 160 is driven to move. The movement of the movable sleeve 160 drives the threaded rod 170 to move, so as to realize non-metered extraction and To discharge the sample, when the rotating wheel 180 is rotated, the threaded rod 170 will rotate in the movable sleeve 160, and move slowly at the same time. When the threaded rod 170 moves, it drives the piston 172 and the limiting rod 190 to move. The movement of the piston 172 squeezes the sample in the sampling tube 100 out of the sampling tube 100 or draws it into the sampling tube 100. When the limiting rod 190 moves, it will contact the limiting plate 140, and the distance between the limiting plate 140 and the limiting rod 190 is adjusted, so as to improve the accuracy of sample addition and prevent excessive sample addition.

[0031] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
