[0003] A sample storage device for river water sampling, disclosed in Chinese Patent Publication No. CN 215917421 U, includes a base plate, a storage box, and two shoulder straps. The storage box is a right-angled triangular prism structure with its bottom surface set on the base plate and X-level steps on the inclined surface. Each step of the storage box has Y sets of storage slots. Each step of the storage box has an observation port located at each storage slot, extending downward from the top surface of the step and penetrating from the front side of the step into the storage slot. The storage slots and observation ports on the X-level steps are aligned longitudinally in the storage box. The two shoulder straps are located on the rear side of the storage box.

[0004] Through the above review of a sample storage device for river water sampling, the following problems were found in the existing technology: 1. The storage trough cannot be rotated to facilitate the placement of sampling tubes by the staff, and the force rod cannot support the support plate; 2. It cannot improve the work efficiency of the staff and slows down the sampling speed. Therefore, we propose a sample storage device for detecting multiple drug residues in water. Utility Model Content

This device solves the problems in related technologies where the storage trough cannot be rotated to allow staff to place the sampling tubes, and the force-bearing rod cannot support the support plate, resulting in reduced work efficiency and slower sampling speed.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A sample storage device for detecting multiple drug residues in water includes a box and a cover. The cover is located on the top of the box. A button is provided on the front side of the box. A steering device is provided inside the box. The steering device includes a fixed plate, which is fixedly connected to the inside of the box. A motor is located at the bottom of the fixed plate.

[0008] Preferably, a force-bearing rod is fixedly connected to the circumferential surface of the support plate, and a circular groove is opened at the top of the fixed plate. This design is beneficial for the support plate to drive the force-bearing rod to rotate.

[0009] Preferably, the force-bearing rod is slidably connected to the inner wall of the circular groove, and the circular groove is located on the movement trajectory of the force-bearing rod. This design is beneficial for the force-bearing rod to slide on the inner wall of the circular groove when it is under force.

[0011] Preferably, a blocking component is rotatably connected to the top of the support plate, and a torsion spring is fixedly connected to the circumferential surface of the blocking component. This design helps the blocking component to block the gear disk and prevent the gear disk from rotating backward.

[0012] Preferably, the groove is located on the movement trajectory of the clamping plate, the toothed disc is hollow, and the circular shaft is slidably connected to the inner wall of the toothed disc.

Detailed Implementation

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1-5As shown, a sample storage device for detecting multiple drug residues in water includes a housing 1 and a cover plate 2. The cover plate 2 is located on the top of the housing 1. A button 3 is located on the front side of the housing 1. A steering device 4 is located inside the housing 1. The steering device 4 includes a fixing plate 41, which is fixedly connected to the inside of the housing 1. A motor 42 is located at the bottom of the fixing plate 41. A rotating shaft 43 is fixedly connected to the end of the output shaft of the motor 42. A support plate 44 is fixedly connected to the circumferential surface of the rotating shaft 43. A storage slot 45 is opened on the top of the support plate 44. A sampling tube 46 is located inside the storage slot 45.

[0026] Please see Figure 2 The force-bearing rod 47 is slidably connected to the inner wall of the circular groove 48, which is located on the movement trajectory of the force-bearing rod 47. This design is beneficial for the force-bearing rod 47 to provide a certain support to the support plate 44 when it rotates.

[0027] Please see Figure 5 The top of the support plate 44 is rotatably connected to a blocking component 57, and a torsion spring 58 is fixedly connected to the circumferential surface of the blocking component 57. This design is beneficial to the torsion spring 58 being able to drive the blocking component 57 to reset when it loses its force.

[0028] Based on the above structure, when staff need to test for multiple drug residues in the water, they first need to sample the water and place the sampled tube 46 in a specially designed storage box 1. Since staff need to sample the water multiple times and conduct multiple tests to ensure accurate results, to save time, after sampling the water with the sample tube 46, staff need to place the sample tube 46 inside the storage trough 45. To save staff from manually moving the sample tube 46, after sealing it, staff only need to press button 3 to start the motor 42, causing the rotating shaft 43 to rotate. When the rotating shaft 43 rotates, it forces the support plate 44 to rotate along with the storage trough 45. After the staff places the first sampling tube 46 inside the storage trough 45, the storage trough 45, which already contains the sampling tube 46, has turned around as it rotates with the support plate 44. The staff can then place the sealed second sampling tube 46 into the empty storage trough 45, allowing the storage trough 45 to work in coordination with the staff. In order to ensure the stability of the support plate 44, the rotation of the support plate 44 forces the force rod 47 to slide on the inner wall of the circular groove 48, which can support the support plate 44, ensuring the efficiency of the staff and thus improving the speed of sampling.

[0029] like Figure 1-5As shown, button 3 is electrically connected to motor 42, and there are three sampling tubes 46 arranged in a circular array on the inner wall of the storage slot 45. This design is beneficial for button 3 to control the start of motor 42.

[0030] Please see Figure 4 The top of the support plate 44 is provided with a fixing device 5, which includes a groove 51. The groove 51 is provided with the top of the support plate 44. The inner wall of the groove 51 is slidably connected with a clamping plate 52. The top of the clamping plate 52 is fixedly connected with a round shaft 53. The top of the support plate 44 is provided with an annular groove 54. The inner wall of the annular groove 54 is slidably connected with a slide rod 55. The circumferential surface of the slide rod 55 is fixedly connected with a gear plate 56. This design is beneficial to the fact that the gear plate 56 forces the slide rod 55 to slide on the inner wall of the annular groove 54 when it rotates.

[0031] Please see Figure 2 A force-bearing rod 47 is fixedly connected to the circumferential surface of the support plate 44, and a circular groove 48 is opened on the top of the fixing plate 41. This design is beneficial for the support plate 44 to support the sampling tube 46.

[0032] Please see Figure 4 , Figure 5 The groove 51 is located on the movement trajectory of the clamping plate 52, the toothed disc 56 is hollow, and the round shaft 53 is slidably connected to the inner wall of the toothed disc 56. This design is beneficial for the clamping plate 52 to fix and clamp the sampling tube 46 when it is under force.

[0033] According to the above structure, in the steering device 4, since centrifugal force is generated when the support plate 44 rotates, in order to prevent the sampling tube 46 from being dislodged from the storage slot 45 or to allow the storage slot 45 to accommodate different types of sampling tubes 46, when the operator places the sampling tube 46 inside the storage slot 45, the operator only needs to rotate the gear disk 56, so that the gear disk 56 slides on the inner wall of the annular groove 54 through the slide rod 55, and causes the circular shaft 53 to slide on the inner wall of the gear disk 56, forcing the clamping plate 52 to slide on the inner wall of the groove 51, so that the clamping plate The clamp 52 can clamp and fix the sampling tube 46 around its entire body. When the toothed disc 56 rotates, the toothed disc 56 and the blocking component 57 come into contact with each other, forcing the blocking component 57 to be subjected to force and make an arc-shaped movement on the top of the support plate 44. After the clamping plate 52 clamps the sampling tube 46, the toothed disc 56 no longer rotates. The blocking component 57 can be reset by the torque of the torsion spring 58, thereby locking the toothed disc 56, effectively preventing the toothed disc 56 from rotating backward, ensuring the safety of the sampling tube 46, and also enabling the storage slot 45 to adapt to different types of sampling tubes 46, thus increasing the utilization efficiency of the storage box 1.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
