[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] Example 1:

[0030] like Figures 1-6 As shown, this embodiment provides a sampling device for drug detection, including a box body 1, a handle 2 fixedly connected to the top of the box body 1, a door 3 rotatably connected to the front of the box body 1, a handle 4 fixedly connected to the right side of the front of the door 3, magnets 5 fixedly connected to opposite sides of the box body 1 and the door 3, a placement frame 6 fixedly connected to the bottom left side of the box body 1, a placement seat 7 fixedly connected to the bottom right side of the box body 1, an adjustment mechanism 8 provided inside the box body 1, a squeezing mechanism 9 provided inside the box body 1, and a limit mechanism 10 provided inside the box body 1.

[0031] The adjustment mechanism 8 includes a cylinder 81 fixedly installed on the inner top wall of the housing 1. The output shaft of the cylinder 81 is fixedly connected to a lifting plate 82. Slider 83 is fixedly connected to both the left and right sides of the lifting plate 82. A rectangular through hole 84 is opened in the middle of the lifting plate 82. A fixing groove 85 is opened on the inner wall of the back side of the rectangular through hole 84.

[0032] The extrusion mechanism 9 includes a connecting groove 91 on the top of the lifting plate 82. A connecting rod 92 is fixedly connected between the inner wall of the front side and the inner wall of the back side of the connecting groove 91. A first spring 93 is sleeved on the outer side of the connecting rod 92. A connecting block 94 is slidably connected to the outer side of the connecting rod 92.

[0033] It should be noted that the handle 2 is designed to facilitate carrying the sampling device, and the handle 4 can be used to easily close and open the door 3. The magnet 5 is used for adsorption of the door 3 and the body 1. The placement frame 6 is used to place a container containing the drug sample to be tested. The drug sample to be tested is liquid, and the placement seat 7 is used to place the test tube.

[0034] Furthermore, such as Figures 1-3 As shown, a box 95 is fixedly connected to the top of the connecting block 94, a second motor 96 is fixedly installed on the inner wall of the back of the box 95, a fixed plate 97 is fixedly connected to the output shaft of the second motor 96, a movable rod 98 is rotatably connected to the front of the fixed plate 97, a support plate 99 is rotatably connected to one end of the movable rod 98, support blocks 910 are fixedly connected to both the left and right sides of the support plate 99, a fixed rod 911 is fixedly connected to the front of the support plate 99, and a limit frame 912 is fixedly connected to the bottom of the fixed rod 911.

[0035] It should be noted that when the second motor 96 is started, the output shaft of the second motor 96 drives the fixed plate 97 to rotate, the fixed plate 97 drives the movable rod 98 to rotate, the movable rod 98 drives the support plate 99 to move upward, and the support plate 99 drives the limit frame 912 to move upward through the fixed rod 911, thereby pulling the piston rod of the syringe 811 and drawing the medicine into the inside of the syringe 811.

[0036] Furthermore, support grooves are provided on both the left and right sides of the inner wall of the box 95. The outer side of the support block 910 is slidably connected to the inner wall of the support groove. One end of the first spring 93 is fixedly connected to the inner wall of the connecting groove 91, and the other end of the first spring 93 is fixedly connected to one side of the connecting block 94.

[0037] Therefore, by setting the support block 910 and the support groove, the support plate 99 can be limited and supported, which increases the stability of the support plate 99 when it moves.

[0038] The front of the box body 95 has a square through hole. The outer side of the fixing rod 911 is slidably connected to the inner wall of the square through hole. Thus, the fixing rod 911 can move up and down inside the square through hole, while limiting and supporting the fixing rod 911, increasing the stability of the fixing rod 911 during movement.

[0039] Furthermore, such as Figures 4-6 As shown, a first motor 86 is fixedly installed on the inner right side of the fixed groove 85. The output shaft of the first motor 86 is fixedly connected to a threaded rod 87. A movable block 88 is threadedly connected to the outer side of the threaded rod 87. A movable plate 89 is fixedly connected to the front side of the movable block 88. A placement hole 810 is opened in the middle of the movable plate 89. A syringe 811 is placed inside the placement hole 810.

[0040] The first motor 86 is started, and its output shaft drives the threaded rod 87 to rotate. The threaded rod 87 drives the movable block 88 to move to the left, thereby moving the syringe 811 to the top of the beaker. The cylinder 81 is then started, and its output shaft drives the lifting plate 82 to move downward, thereby moving the syringe 811 downward into the beaker. Simultaneously, the outer side of the movable block 88 is slidably connected to the inner wall of the fixed groove 85. Sliding grooves are provided on both the left and right sides of the inner wall of the housing 1. The outer side of the slider 83 is slidably connected to the inner wall of the sliding groove, thus setting the slider 83 and the sliding groove to provide limiting support for the lifting plate 82, increasing the stability of the lifting plate 82 during movement.

[0041] Example 2:

[0042] The only difference between this embodiment and Embodiment 1 is that, Figures 4-6 As shown, the limiting mechanism 10 includes limiting grooves 101 opened on the left and right sides of the movable plate 89. Multiple second springs 102 are fixedly connected to the inner walls of the opposite side of the two limiting grooves 101. Limiting plates 103 are fixedly connected to the opposite side of the multiple second springs 102 on the left and the multiple second springs 102 on the right.

[0043] In use, push the box 95 backward. The box 95 drives the connecting block 94 to move backward outside the connecting rod 92, squeezing the first spring 93. This causes the box 95 and the limiting frame 912 to move backward, causing the limiting frame 912 to detach from the piston rod of the syringe 811. Then, the two limiting plates 103 are squeezed in opposite directions. The two limiting plates 103 move in opposite directions, stretching the second spring 102. This causes the two limiting plates 103 to move in opposite directions inside the limiting groove 101, making it easier to pull the syringe 811 out of the placement hole 810 and to replace the syringe 811.

[0044] Meanwhile, the outer side of the limiting plate 103 is slidably connected to the inner wall of the limiting groove 101, and the limiting plate 103 is U-shaped, so as to limit and fix the empty cylinder of the syringe 811, thereby increasing the overall positional stability of the syringe 811 when the piston rod of the syringe 811 is stretched and squeezed.

[0045] The working principle of this invention is as follows: In use, a container holding the drug sample is placed inside the placement frame 6, and the test tube is placed inside the placement seat. The first motor 86 is started, and its output shaft drives the threaded rod 87 to rotate. The threaded rod 87 drives the movable block 88 to move to the left, thereby moving the syringe 811 to the top of the beaker. The cylinder 81 is then started, and its output shaft drives the lifting plate 82 to move downwards. By setting a slider 83 and a groove, the lifting plate 82 is limited and supported, increasing its stability during movement. This causes the syringe 811 to move downwards into the beaker. The second motor 96 is then started, and its output shaft drives the fixed plate 97 to rotate. The fixed plate 97 drives the movable rod 98 to rotate, and the movable rod 98 drives the support plate 99 to move upwards. By setting support block 910 and support groove, the support plate 99 is limited and supported, which increases the stability of the support plate 99 during movement. The support plate 99 drives the limiting frame 912 to move upward through the fixed rod 911, thereby pulling the piston rod of the syringe 811 and drawing the medicine into the inside of the syringe 811. By controlling the stretching height, the amount of medicine drawn can be controlled. Then, the height of the syringe 811 is adjusted upward, then moved to the top of the test tube to the right, and then the syringe 811 is moved downward to insert the bottom of the syringe 811 into the inside of the test tube. Then, the second motor 96 is started, causing the fixed plate 97 to reverse, thereby squeezing the piston rod of the syringe 811 and releasing the drug sample to be tested into the inside of the test tube for subsequent sample testing. This improves the efficiency of sample collection.

[0046] Furthermore, by setting a limiting mechanism 10, the box 95 is pushed backward, and the box 95 drives the connecting block 94 to move backward outside the connecting rod 92 to squeeze the first spring 93, thereby causing the box 95 and the limiting frame 912 to move backward, so that the limiting frame 912 is dislodged from the piston rod of the syringe 811, and then the two limiting plates 103 are squeezed in opposite directions. The two limiting plates 103 move in opposite directions to stretch the second spring 102, thereby causing the two limiting plates 103 to move in opposite directions inside the limiting groove 101, which facilitates the removal of the syringe 811 from the inside of the placement hole 810 for replacement.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
