A rotating plate is connected to the top of the first turntable. Connecting rods are fixedly connected to both sides of the top of the rotating plate. Adjustment grooves are opened on the side walls of the connecting rods. It can achieve the effect of placing drug test tubes by setting up a first turntable, rotating plate, protective base, connecting rods, placement plate, first spring and clamping plate. At the same time, the placement plate and protective base can satisfy the effect of clamping test tubes of different sizes, and the clamping plate can satisfy the effect of clamping test tubes of different sizes, avoiding shaking caused by unstable clamping. It is beneficial to satisfy the effect of stable clamping of drug test tubes of different sizes, and at the same time, it is beneficial to improve the utilization rate of the drug testing sampling device.

[0004] The above-mentioned device is beneficial for achieving stable clamping of test tubes of different sizes. According to the instruction manual and the attached drawings, the device clamps the test tubes only through the first spring and the clamping plate. Since the spring itself has a certain elasticity, the rotating mechanism at the bottom end will cause the clamping to be unstable when it moves, which will affect the test results. Utility Model Content

[0005] The purpose of this invention is to provide a sampling device for pharmaceutical testing, which addresses the problem that when a test tube is clamped solely by a first spring and a clamping plate, the spring's inherent elasticity causes instability in the bottom rotating mechanism during movement, thus affecting the test results.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for drug testing, comprising a fixed base and a sampling box, wherein the sampling box is fixedly installed on the top of the fixed base, a rotating motor is fixedly installed inside the sampling box, and a rotating plate is fixedly installed on the output shaft at the top of the rotating motor, and connecting rods are symmetrically fixedly installed on the top of the rotating plate, and placement plates are fixedly installed on the tops of the two sets of connecting rods, wherein placement grooves are evenly and circumferentially formed on the top of the placement plates, and connecting rods are symmetrically and slidably connected inside the placement grooves, and a clamping plate is fixedly installed at one end of the connecting rods, a connecting gear is rotatably connected inside the placement plates, and an arc-shaped groove is formed at the top of the connecting gear for the connecting rods to slide, a connecting shaft adapted to the arc-shaped groove is fixedly installed at the bottom end of the connecting rods, and a drive gear is rotatably connected inside the placement plates, and the drive gear meshes with the connecting gear.

[0007] As a further embodiment of this utility model: a rotating rod is rotatably connected to the top of the placement plate, and the rotating rod passes through the placement plate and is fixedly installed with the drive gear, and a rotating disk is fixedly installed at the top of the rotating rod.

[0008] As a further embodiment of this utility model: a limiting gear is fixedly installed at the top of the placement plate and directly below the rotating disk, and a groove is provided at the bottom of the rotating disk, and a locking block is slidably connected inside the groove, the locking block being adapted to the tooth groove of the limiting gear.

[0009] As a further embodiment of this utility model: a pull rod is slidably connected to the top of the rotating disk, and the pull rod is fixedly installed in the groove and the locking block. A return spring is fixedly installed inside the groove and is sleeved on the outer periphery of the pull rod.

[0010] As a further embodiment of this utility model: a protective base is provided at the top of the rotating plate, and protective sleeves are symmetrically fixedly installed at the top of the protective base. Multiple sets of protective sleeves are located directly below multiple sets of placement slots. Connecting springs are symmetrically fixedly installed inside the protective sleeves, and a protective block for clamping the test tube is fixedly installed at one end of the connecting spring.

[0011] As a further improvement of this utility model, a sponge block is fixedly installed at one end of the clamping plate.

[0012] As a further improvement of this utility model: the bottom end of the fixed base is symmetrically fixed with support rods for support, and one end of the sampling box is rotatably connected with a locking box door for locking.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This utility model employs a dual-fixing system: a bottom elastic clamp and a top rigid clamp. The connecting spring of the protective sleeve pushes the protective block to initially fix the bottom of the test tube, preventing bottom wobbling. The top is driven by gears, with the rotating disk driving the drive gear and connecting gear in tandem, allowing the clamping plate to precisely approach the test tube and achieve rigid clamping. This avoids loosening caused by simple spring elasticity. The locking block and the limiting gear work together to lock the transmission structure. The sponge block on the clamping plate also protects the test tube, ensuring overall stable clamping and preventing the test tube from shifting when the rotating plate rotates, thus guaranteeing accurate drug testing results.

The embodiments of this utility model will be described below based on its overall structure.

[0018] Reference Figures 1 to 6 In this embodiment of the present invention, a sampling device for drug testing includes a fixed base 1 and a sampling box 2. The sampling box 2 is fixedly installed on the top of the fixed base 1. A rotating motor 8 is fixedly installed inside the sampling box 2, and a rotating plate 5 is fixedly installed on the output shaft at the top of the rotating motor 8. Connecting rods 7 are symmetrically fixedly installed on the top of the rotating plate 5. Placement plates 6 are fixedly installed on the tops of the two sets of connecting rods 7. Placement grooves 13 are evenly arranged around the top of the placement plates 6. Connecting rods 14 are symmetrically slidably connected inside the placement grooves 13, and one end of the connecting rods 14 is fixedly installed. The placement plate 6 is equipped with a clamping plate 15. A connecting gear 17 is rotatably connected inside the placement plate 6. The top of the connecting gear 17 has an arc-shaped groove 19 for the connecting rod 14 to slide. A connecting shaft that matches the arc-shaped groove 19 is fixedly installed at the bottom of the connecting rod 14. A drive gear 20 is rotatably connected inside the placement plate 6 and meshes with the connecting gear 17. A rotating rod 21 is rotatably connected to the top of the placement plate 6 and is fixedly installed through the placement plate 6 and the drive gear 20. A rotating disk 16 is fixedly installed at the top of the rotating rod 21.

[0019] The above-mentioned scheme employs the following: the sampling box 2, the rotating motor 8, and the rotating plate 5 are all prior art referenced in the prior art documents and are not described in detail in this application. The placement plate 6 is made of high-strength aluminum alloy, which has both good load-bearing capacity and corrosion resistance. The placement groove 13, as part of the placement plate 6, is made of the same material, and its smooth inner wall ensures smooth sliding of the connecting rod 14. The connecting rod 14 is made of hard alloy, which has excellent rigidity and is not easily deformed. The clamping plate 15 is made of wear-resistant engineering plastic, which ensures clamping force and avoids scratching the clamped object. The connecting gear 17 and the drive gear 20 are made of high-strength alloy steel. The materials of the arc groove 19 and the connecting shaft are the same as those of the connecting gear 17 and the connecting rod 14, respectively, to ensure compatibility and durability. The rotating rod 21 is made of stainless steel, which is rust-proof and has high strength. The rotating disk 16 is made of engineering plastic or aluminum alloy, and its surface is provided with anti-slip textures to facilitate force application and rotation. The advantage of this structure is that the top of the placement plate 6... The placement slot 13 provides positioning space for the object. When the rotating disk 16 is rotated, it drives the rotating rod 21 and the drive gear 20 fixed thereto to rotate. The drive gear 20 meshes with the connecting gear 17, causing the connecting gear 17 to rotate synchronously. The arc-shaped groove 19 on the connecting gear 17 drives the connecting rod 14 to slide symmetrically in the placement slot 13 through the connecting shaft, thereby causing the two sets of clamping plates 15 to move closer or further away synchronously, achieving precise clamping and releasing of the object. This avoids the problem of uneven force distribution that occurs when manually adjusting the clamping plates 15. The arc-shaped design of the arc-shaped groove 19 can smoothly convert the circular motion of the connecting gear 17 into the linear motion of the connecting rod 14, ensuring a smooth and uninterrupted clamping process. The overall structure achieves power transmission through gear transmission, which has high transmission efficiency and controllable clamping force. Combined with the material design of the clamping plates 15, it can not only firmly clamp the object but also protect the surface of the object. At the same time, the setting of the rotating disk 16 makes the operation more convenient and labor-saving, greatly improving the efficiency and stability of object clamping.

[0020] Reference Figures 1 to 6 A limiting gear 22 is fixedly installed at the top of the placement plate 6 and directly below the rotating disk 16. A groove 23 is opened at the bottom of the rotating disk 16, and a locking block 24 is slidably connected inside the groove 23. The locking block 24 is adapted to the tooth groove of the limiting gear 22. A pull rod 25 is slidably connected at the top of the rotating disk 16, and the pull rod 25 passes through the groove 23 and is fixedly installed with the locking block 24. A return spring 26 is fixedly installed inside the groove 23, and the return spring 26 is sleeved on the outer periphery of the pull rod 25. The above-mentioned scheme employs the following: The locking block 24 is made of hard alloy, possessing excellent wear resistance and impact resistance, and can be precisely embedded in the tooth groove of the limiting gear 22. The groove 23, as part of the rotating disk 16, is made of the same material as the rotating disk 16, with a smooth inner wall to ensure smooth sliding of the locking block 24. The pull rod 25 is made of stainless steel, which is rust-proof and high-strength, facilitating operation. The return spring 26 is made of high-elasticity spring steel, with stable elasticity, providing a continuous return force for the locking block 24. Furthermore, its placement around the pull rod 25 prevents spring misalignment. The advantage of this structure is that the limiting gear 22 at the top of the placement plate 6 matches the locking block 24 in the groove 23 at the bottom of the rotating disk 16. Under the elastic force of the return spring 26, the locking block 24 remains embedded in the tooth groove of the limiting gear 22, effectively limiting the autonomous rotation of the rotating disk 16 and thus preventing the drive gear from... 20. Accidental rotation of the connecting gear 17 causes displacement of the connecting rod 14, ensuring the stability of the clamping plate 15's clamping state of the object and preventing the object from loosening during processing or handling. When it is necessary to adjust the clamping force or release the object, pulling the lever 25 upwards will cause the locking block 24 to compress the return spring 26 and disengage from the tooth groove of the limiting gear 22, releasing the limitation on the rotating disk 16. At this time, the rotating disk 16 can be rotated for adjustment. After the adjustment is completed, the lever 25 is released, and the locking block 24 automatically resets under the action of the return spring 26 and re-engages the limiting gear 22, achieving fixation again. This structure works in conjunction with the rotating disk 16, rotating rod 21, drive gear 20, and other components to ensure the stability of the clamping state and make the adjustment operation convenient and efficient. Limiting and unlocking can be completed without additional tools, further improving the reliability and operational flexibility of the placement plate 6 in clamping the object.

[0021] Reference Figures 1 to 6 The top of the rotating plate 5 is provided with a protective base 9. The top of the protective base 9 is symmetrically fixed with protective sleeves 10. Multiple sets of protective sleeves 10 are located directly below multiple sets of placement slots 13. Connecting springs 11 are symmetrically fixed inside the protective sleeves 10. A protective block 12 for clamping the test tube is fixedly installed at one end of the connecting spring 11. The above-mentioned scheme employs the following: the protective base 9 is prior art as described in the referenced documents and is not elaborated upon in this application; the protective sleeve 10 is made of silicone, which is soft and elastic, providing cushioning protection for the test tubes; the connecting spring 11 is made of high-elasticity spring steel, possessing stable resilience and fatigue resistance; and the protective block 12 is made of food-grade silicone, with a smooth surface and a certain degree of friction, preventing scratches on the test tube surface while providing reliable clamping. The advantage of this structure is that the protective base 9 at the top of the rotating plate 5 provides a stable mounting base for the protective sleeve 10; multiple sets of protective sleeves 10 are located directly below multiple sets of placement slots 13; when the test tube is placed in the placement slot 13 and extends downwards, it can be precisely inserted into the corresponding protective sleeve 10, forming a double positioning system for protection. The connecting spring 11 inside the sleeve 10 cooperates with the protective block 12. The elastic potential energy of the connecting spring 11 pushes the protective block 12 to fit tightly against the outer wall of the test tube. It can adapt to test tubes of different diameters and provide uniform clamping force to prevent the test tube from shaking or tipping. The soft material of the protective sleeve 10 and the protective block 12 can absorb the influence of external vibration on the test tube and prevent the test tube from being damaged by collision or vibration. It is especially suitable for test tubes containing liquid or fragile ones. This structure cooperates with the placement groove 13, clamping plate 15, etc. The upper part of the test tube is fixed by the clamping plate 15, and the lower part of the test tube is stabilized by the protective block 12 inside the protective sleeve 10, forming an all-round clamping and protection system. This greatly improves the stability and safety of test tube placement, while being compatible with various specifications of test tubes, enhancing the versatility and practicality of the device.

[0022] Reference Figures 1 to 6 A sponge block 18 is fixedly installed at one end of the clamping plate 15; The above solution employs a high-density elastic sponge block 18, which has a soft surface and good cushioning properties. Its uniform internal pores provide a certain degree of adsorption and resilience. The connection point with the clamping plate 15 can be bonded with environmentally friendly adhesive, ensuring a secure and non-detachable fixation. The advantage of this structure is that the sponge block 18 at one end of the clamping plate 15 directly contacts the object being clamped. When the clamping plate 15 approaches the object under the influence of the connecting rod 14, the sponge block 18 first contacts the object's surface and undergoes elastic deformation, effectively dispersing the clamping force and preventing the clamping plate 15 from causing hard compression or scratches to the object. Especially suitable for objects with fragile and easily worn surfaces, the softness of the sponge block 18 can increase the friction with the object's surface, improve the stability of the clamping, and prevent the object from slipping during clamping. At the same time, the elastic deformation of the sponge block 18 can adapt to the slight unevenness of the object's surface, ensuring a tighter and more secure clamping. This structure, in conjunction with the clamping plate 15, connecting rod 14, connecting gear 17, etc., further enhances the protection of the clamped object while maintaining the original clamping force adjustment function. It ensures the stability of the clamping and avoids damage to the object, thus improving the applicability and safety of the device.

[0023] Reference Figures 1 to 6 The bottom of the fixed base 1 is symmetrically fixed with support rods 4 for support, and one end of the sampling box 2 is rotatably connected with a locking box door 3 for locking. The above-mentioned solution adopts the prior art for both the support rod 4 and the locking box door 3, which are not described in detail in this application.

[0024] The working principle of this utility model is as follows: When sampling medicine, the test tube containing the medicine is first placed in the placement groove 13 at the top of the placement plate 6. The bottom end of the test tube is inserted into the protective sleeve 10 on the protective base 9 at the top of the rotating plate 5. The connecting springs 11 symmetrically fixed inside the protective sleeve 10 push the protective block 12 to fit against the outer wall of the test tube, providing initial elastic clamping to the bottom end of the test tube to prevent the bottom of the test tube from shaking. Then, the top end of the test tube is stably clamped: the pull rod 25 at the top of the rotating disk 16 is pulled upward. The pull rod 25 passes through the groove 23 and drives the locking block 24 to slide, compressing the reset spring 26 inside the groove 23 and sleeved on the outer periphery of the pull rod 25, so that the locking block 24 disengages from the tooth groove of the limiting gear 22 at the top of the placement plate 6, releasing the rotation restriction on the rotating disk 16. The rotating disk 16 is rotated, which drives the rotating rod 21 fixed at the bottom end to rotate synchronously. The rotating rod 21 passes through the placement plate 6 and the driving gear. The fixed connection 20 drives the drive gear 20 to rotate. The drive gear 20 meshes with the connecting gear 17 inside the placement plate 6, causing the connecting gear 17 to rotate. The top of the connecting gear 17 has an arc-shaped groove 19. The bottom shaft of the symmetrically sliding connecting rod 14 inside the placement groove 13 is adapted to the arc-shaped groove 19. When the connecting gear 17 rotates, the arc-shaped groove 19 drives the two sets of connecting rods 14 to slide towards the center of the placement groove 13 through the connecting shaft. The clamping plate 15 at one end of the connecting rod 14 then approaches the test tube until the sponge block 18 at one end of the clamping plate 15 adheres to the outer wall of the top of the test tube, achieving rigid clamping of the top of the test tube. The gear transmission structure avoids the clamping looseness caused by the elasticity of the spring. The pull rod 25 is released, and the reset spring 26 pushes the card block 24 to re-engage into the tooth groove of the limiting gear 22, fixing the position of the rotating disk 16 and the drive gear 20, ensuring that the clamping plate 15 stably clamps the test tube.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
