[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] like Figures 1-9 As shown, this utility model discloses a drug testing dissolver, comprising a shaker body 1 and a swing unit. The swing unit includes a swing rod 2, which is installed on the left and right sides of the shaker body 1. The swing rod 2 has a mounting groove 3, and cylindrical racks 4 are symmetrically arranged in the mounting groove 3. One end of the cylindrical rack 4 is provided with a clamping device 5 (the clamping device 5 is used to fix and clamp the reagent bottle, which is prior art, and its specific structure is not described here). The mounting groove 3 is also provided with an adjusting gear 8, which meshes with the cylindrical racks 4 on both sides respectively. The top of the swing rod 2 is also provided with a drive assembly 6, which is connected to the adjusting gear 8 in a transmission manner.

[0030] The swing rod 2 is detachably mounted on the output shafts on both sides of the vibrator body 1 via bolts, allowing the vibrator body 1 to control the reciprocating swing of the swing rod 2 (the working principle of the vibrator body 1 controlling the reciprocating swing of the output shaft is existing technology and will not be elaborated here). When it is necessary to adapt to reagent bottles of different specifications or adjust the load distribution, the drive assembly 6 drives the adjusting gear 8 to rotate. Since the adjusting gear 8 meshes with the cylindrical racks 4 on both sides, when the adjusting gear 8 rotates, it simultaneously pushes the racks on both sides to make synchronous reverse linear movements along the mounting groove 3 (when one rack extends outward, the other rack extends outward synchronously; when one rack retracts inward, the other rack retracts inward synchronously), thereby driving the clamping device 5 and the reagent bottle to achieve synchronous position adjustment. This design structurally ensures the consistency of the extension length of the sample containers on both sides, effectively avoiding the load imbalance problem caused by separate adjustment in traditional equipment, reducing vibration and noise during equipment operation, improving the uniformity and stability of sample processing, and extending the service life of the equipment.

[0031] like Figures 1-9As shown, the drive assembly 6 includes a housing 21, a worm 22, a worm wheel 23, and a drive shaft 24. The housing 21 is fitted to the top of the swing rod 2. The worm 22 is rotatably mounted inside the housing 21. The drive shaft 24 passes through the top of the swing rod 2 and extends into the mounting groove 3. The worm wheel 23 is fixed to the top of the drive shaft 24 and meshes with the worm 22. The bottom end of the drive shaft 24 is connected to the adjusting gear 8. One end of the worm 22 rotates through the housing 21 and is fixed to a knob 25. A flat key 26 is integrally formed on the outer peripheral wall of the drive shaft 24. The flat key 26 extends along the axial direction of the shaft. A keyway 27 adapted to the flat key 26 is opened on the inner wall of the mounting hole of the adjusting gear 8. The flat key 26 and the keyway 27 slide together. The drive shaft 24 contacts the bottom wall of the mounting groove 3.

[0032] The drive assembly 6, as a key structure in the drug testing dissolver for adjusting the position of the sample container, works in conjunction with the key 26 and keyway 27 to ensure stable power transmission while also facilitating easy assembly and disassembly of components. When the drive shaft 24 rotates under the drive of the worm gear 23, the rotational torque of the drive shaft 24 is directly transmitted to the adjusting gear 8 through the key 26 due to the circumferential limiting effect of the key 26 and keyway 27. This causes the adjusting gear 8 to rotate synchronously, thereby driving the cylindrical racks 4 on both sides to move linearly, thus adjusting the position of the sample container. The adjusting gear 8 is installed in the middle of the mounting groove 3. After the mounting hole on it mates with the drive shaft 24, the adjusting gear 8 is restricted to rotate within the mounting groove 3. After the adjusting gear 8 meshes with the cylindrical racks 4 on both sides, it can limit the sliding of the cylindrical racks 4, ensuring that the cylindrical racks 4 can only slide and cannot rotate. The inner walls of both sides of the mounting groove 3 are arc-shaped, which can slide and fit against the cylindrical outer walls of the cylindrical racks 4, ensuring smooth sliding.

[0033] like Figures 1-9 As shown, a horizontal rod 28 runs through the housing 21 and is parallel to the swing rod 2. The swing rod 2 is provided with a fixing component 7, which is connected to both ends of the horizontal rod 28. The top and bottom of the housing 21 are open, and the bottom of the housing 21 is provided with an arc-shaped opening 29 that fits with the swing rod 2. The fixing component 7 includes a collar 71, a vertical rod 72, and a sleeve 73. The collar 71 is fixedly sleeved on the swing rod 2 by bolts. The vertical rod 72 is fixed to the top of the collar 71. The sleeve 73 is fixed to the top of the vertical rod 72, and one end of the sleeve 73 is sealed. One end of the horizontal rod 28 slides into the open end of the sleeve 73.

[0034] The fixed component 7 and the horizontal bar 28 provide two-point symmetrical support for the housing 21. The horizontal bar 28 and the sleeve 73 are connected by a sliding plug-in type. The collar 71 is fixed and disassembled with the swing rod 2 by bolts. The installation and removal of the housing 21 can be completed without complicated tools, which facilitates the maintenance and repair of the drive component 6.

[0035] likeFigures 1-9 As shown, an external threaded tube 210 is provided at the point where the drive shaft 24 passes through the swing rod 2. The external threaded tube 210 is threaded to the top of the swing rod 2. The drive shaft 24 moves through the external threaded tube 210. An avoidance groove 211 is provided inside the external threaded tube 210. The flat key 26 passes through the avoidance groove 211.

[0036] The externally threaded tube 210 is a hollow tubular structure with external threads machined on the outside of the tube body. It is adapted to the internally threaded hole pre-set on the top of the swing rod 2 and is fixedly connected to the swing rod 2 by thread engagement. The inside of the tube body is a through channel for the drive shaft 24 to move through. The inner diameter of the channel is adapted to the outer diameter of the drive shaft 24 to ensure that there is no obvious shaking when the drive shaft 24 rotates. An axial clearance groove 211 is provided inside the externally threaded tube 210. The clearance groove 211 passes through the upper and lower ends of the externally threaded tube 210. When the drive shaft 24 passes through the externally threaded tube 210, the flat key 26 can pass through the clearance groove 211, which avoids interference between the flat key 26 and the inner wall of the externally threaded tube 210 and does not affect the rotational movement and axial disassembly and assembly of the drive shaft 24.

[0037] In practical use, the sample bottle that needs to be shaken and mixed is fixed on the clamping device 5, and the main body of the shaker 1 is started to make the swing rod 2 swing to shake the reagent bottle (the working principle of the main body of the shaker 1 driving the swing rod 2 to swing back and forth and the clamping structure of the clamping device 5 are existing technologies and will not be described in detail here).

[0038] When the position of the reagent bottle needs to be adjusted, simply turn the knob 25, which will drive the worm gear 22, worm wheel 23, drive shaft 24 and adjusting gear 8 to rotate in sequence. The adjusting gear 8 drives the two cylindrical racks 4 to move synchronously, thereby adjusting the position of the reagent bottle to move closer to or further away from the swing arm 2. The moving distance of the two cylindrical racks 4 is always consistent, ensuring that the weight is balanced on both sides of the swing arm 2.

[0039] Disassembly and assembly steps of cylindrical rack 4: When disassembling, first remove the bolts on the collar 71 from the swing rod 2 to release the fixation of the collar 71, allowing it to slide on the swing rod 2. Then slide the sleeve 73 away from the horizontal rod 28, releasing the limit on the horizontal rod 28. At this time, the housing 21 can be removed from the swing rod 2. At the same time, the drive shaft 24 is also pulled out from the adjusting gear 8 and the external threaded tube 210. At this time, the limit on the adjusting gear 8 is released. At this time, the cylindrical rack 4 and the adjusting gear 8 can be pulled out from the mounting groove 3 at the same time. Then slide the collar 71 out from the swing rod 2 to complete the disassembly of the parts on the swing rod 2.

[0040] During installation, first, slide the collar 71 onto the swing rod 2, engage the cylindrical rack 4 and the adjusting gear 8, and simultaneously insert them into the mounting groove 3. Then, snap the housing 21 onto the swing rod 2, and pass the drive shaft 24 through the external threaded tube 210 and the mounting hole of the adjusting gear 8. The bottom end of the drive shaft 24 contacts the bottom wall of the mounting groove 3. Then, slide the collar 71 so that the sleeve 73 on the collar 71 aligns with the horizontal rod 28. Finally, use bolts to fix the collar 71 to the swing rod 2, thus completing the installation of the components on the swing rod 2.
