Description

Technical Field

[0001] This utility model relates to the field of oscillator technology, specifically to a laboratory sample oscillator. Background Technology

[0002] Shakers are core equipment in laboratories used for mixing, homogenizing, or shaking samples. They are widely used in fields such as biochemistry, molecular biology, environmental monitoring, and medical testing. Their ability to stably hold sample containers directly affects the repeatability and reliability of experimental results.

[0003] Utility model patent CN221333790U discloses a constant-temperature oscillator, the structure of which includes: a housing with an internal support plate; a first clamping part mounted on the support plate, having multiple first elastic plates arranged circumferentially thereon, and the upper end of each first elastic plate having an abutment portion; and a second clamping part rotatably engaged with the upper end of the first elastic plates, the upper end of which has a tightening member for bringing the upper ends of the second clamping parts closer together and abutting against the neck of a glass bottle with a neck. Through the cooperation of the elastic rope and the tightening member, the upper end of the second elastic plate easily abuts against the neck of the bottle body, thereby allowing the first and second clamping parts to clamp the bottle body and neck respectively, ensuring greater stability for taller triangular bottles.

[0004] Although the aforementioned patent can achieve stable fixation of larger triangular bottles, the adjustable range of the clamping components is relatively small. By setting multiple sizes of first clamping parts on the support plate to accommodate triangular bottles of different sizes, it results in low space utilization within the oscillator; furthermore, the clamping operation of this oscillator is also quite complex. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned technical problems and provide a laboratory sample shaker.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a laboratory sample shaker, comprising a shaker housing, a placement plate, and a fixing mechanism. The placement plate is provided with multiple fixing areas with anti-slip design. The fixing mechanism is disposed above the fixing areas and includes multiple clamping parts arranged along the circumferential direction. Each clamping part includes a slider, an inclined clamping plate, and a spring. The placement plate is provided with a groove corresponding to the clamping part. The slider and the spring are both located in the groove, and the two ends of the spring are fixedly connected to the groove and the end of the slider, respectively. The bottom of the inclined clamping plate is rotatably disposed on the top of the slider, and the top of the slider is provided with a fixing mechanism for fixing the inclined clamping plate. The length of the inclined clamping plate is adjustable, and its top is provided with an outwardly bent extrusion section. The connection between the extrusion section and the inclined section of the inclined clamping plate is the clamping point.

[0007] Furthermore, the longitudinal section of the slider and the groove is a cross-shaped structure.

[0008] Furthermore, the inclined clamping plate includes a fixed part and a telescopic part, the bottom of the fixed part is connected to the slider, and the extrusion section is disposed at the top of the telescopic part.

[0009] Furthermore, the outer side of the fixing part is provided with a telescopic groove, the telescopic part is located in the telescopic groove, and anti-slip teeth are provided on the side of the telescopic groove and the telescopic part that are close to each other, and the anti-slip teeth of the two cooperate with each other.

[0010] Furthermore, the top outer side of the telescopic groove is provided with a threaded post and a nut is provided in conjunction with it. The telescopic part is provided with a strip-shaped through hole, through which the threaded post passes and the nut is installed on the outer side of the telescopic part.

[0011] Furthermore, the fixing part has an L-shaped structure, the top of the slider is provided with a rotating seat, the vertical part and the horizontal part of the fixing part are provided with a rotating shaft, and are rotatably connected to the rotating seat through the rotating shaft. The fixing mechanism includes a fan-shaped plate, a limiting hole and a limiting post. The rotating seat is provided with fan-shaped plates on both sides, the horizontal part of the fixing part is located between the two fan-shaped plates, and the fan-shaped plates are provided with multiple limiting holes. The horizontal part of the fixing part is provided with elastic telescopic limiting posts on both sides, and the elastic telescopic limiting posts extend into the limiting holes to fix the tilt angle of the tilting clamping plate.

[0012] Furthermore, each of the limiting holes is provided with a button for squeezing the elastic telescopic limiting post. A connecting spring is sleeved on the button, and the two ends of the connecting spring are fixedly connected to the outer side of the sector plate and the side wall of the button, respectively.

[0013] Furthermore, an anti-slip pad is provided on the top surface of the fixed area.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model utilizes the synergistic action of a slider and a spring to enable the tilting clamping plate to open and close. Furthermore, the tilting clamping plate and the slider are connected by a rotating mechanism, allowing for adjustment of the tilt angle. In addition, the tilting clamping plate has a telescopic function to accommodate the clamping needs of triangular bottles of different sizes, offering a wide adjustment range that covers almost all commonly used triangular bottles.

[0016] 2. This utility model has an anti-slip fixing area at the bottom to fix the bottom position of the triangular bottle. At the same time, the upper part of the triangular bottle is firmly clamped by the clamping point at the top of the inclined clamping plate, thereby achieving a reliable fixing effect.

[0017] 3. This utility model features an outwardly bent compression section at the top of the inclined clamping plate. When placing a triangular bottle, the bottom of the bottle contacts the compression section, and pressing down will move the slider to move the inclined clamping plate outward. Once the triangular bottle is between multiple inclined clamping plates, the spring will automatically reset the clamping plate, achieving the clamping function. The operation is simple and convenient. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 are within the protection scope of the present utility model.

[0024] Embodiments of this utility model: such as Figure 1-4 As shown, a laboratory sample shaker includes a shaker housing 1, a placement plate 2, and a fixing mechanism. The shaker housing 1 is located below the placement plate 2, and this shaking mechanism is the same as that in existing shakers, so it will not be described in detail here. The placement plate 2 has multiple fixing areas 3 with anti-slip design (the top surface of each fixing area 3 has an anti-slip pad 24, which can be a silicone anti-slip pad). The fixing mechanism is positioned above the fixing areas 3.

[0025] like Figure 2 , 3As shown, the fixing mechanism includes a plurality of clamping parts 4 arranged along the circumferential direction (preferably 3 in this embodiment). Each clamping part 4 includes a slider 5, an inclined clamping plate 6, and a spring 7. The placement plate 2 is provided with a groove 8 corresponding to the clamping part 4. Both the slider 5 and the spring 7 are located in the groove 8 (the longitudinal section of the slider 5 and the groove 8 is a cross-shaped structure to prevent the slider 5 from falling out of the groove 8). The two ends of the spring 7 are fixedly connected to the groove 8 and the end of the slider 5, respectively, and can continuously apply a centripetal elastic force to the slider 5.

[0026] like Figure 2 , 3 As shown, the length of the inclined clamping plate 6 is adjustable. It includes a fixed part 11 and a telescopic part 12. The fixed part 11 has an L-shaped structure. The top of the slider 5 is provided with a rotating seat 18. A rotating shaft is provided at the connection between the vertical part and the horizontal part of the fixed part 11, and it is rotatably connected to the rotating seat 18 through the rotating shaft. Fan-shaped plates 19 are provided on both sides of the rotating seat 18. The horizontal part of the fixed part 11 is located between the two fan-shaped plates 19, and the fan-shaped plates 19 are provided with multiple limiting holes 20. The horizontal part of the fixed part 11 is provided with elastic telescopic limiting posts 21 (which include telescopic springs and telescopic posts. The fixed part 11 is provided with telescopic positioning grooves, and the telescopic springs and telescopic posts are located in the telescopic positioning grooves. This structure is prior art and is not shown in the figure). The elastic telescopic limiting posts 21 extend into the limiting holes 20 to fix the tilt angle of the inclined clamping plate 6.

[0027] like Figure 2 , 3 As shown, each of the limiting holes 20 is provided with a button 22 for squeezing the elastic telescopic limiting post 21. A connecting spring 23 is sleeved on the button 22. The two ends of the connecting spring 23 are fixedly connected to the outer side of the fan-shaped plate 19 and the side wall of the button 22, respectively.

[0028] like Figure 2 , 3 As shown, the top of the telescopic part 12 is provided with an outwardly bent extrusion section 9, which facilitates the placement of the triangular bottle into the fixing mechanism. The connection between the extrusion section 9 and the inclined section of the telescopic part 12 is a clamping point 10. A rubber buffer layer can be pasted on the surface of the clamping point 10 to avoid damage to the bottle body during clamping.

[0029] like Figure 2 , 3 As shown, the outer side of the fixing part 11 is provided with a telescopic groove 13, and the telescopic part 12 is located in the telescopic groove 13. The telescopic groove 13 and the telescopic part 12 are provided with anti-slip teeth 14 on the side that are close to each other, and the anti-slip teeth 14 of the two cooperate with each other.

[0030] like Figure 2 , 3As shown, the top outer side of the telescopic groove 13 is provided with a threaded post 15 and a nut 16 is provided in cooperation. The telescopic part 12 is provided with a strip-shaped through hole 17. The threaded post 15 passes through the strip-shaped through hole 17 and the nut 16 is installed on the outer side of the telescopic part 12.

[0031] When this utility model is used in a specific way:

[0032] Angle adjustment: Press button 22 on the sector plate 19 to disengage the elastic telescopic limit post 21 from the limit hole 20, rotate the tilting clamping plate 6 to the angle that matches the cone of the triangular bottle (e.g., 60° for a 250ml triangular bottle and 75° for a 500ml triangular bottle), and release button 22 to allow the elastic telescopic limit post 21 to automatically engage with the corresponding limit hole 20.

[0033] Length adjustment: Loosen the nut 16, pull the telescopic part 12 along the telescopic groove 13 until the clamping point 10 is aligned with the upper part of the triangular bottle, the anti-slip teeth 14 engage to achieve temporary fixation, and then tighten the nut 16 to complete the length lock.

[0034] Sample fixing: Place the triangular bottle with the bottom facing down, so that the bottom of the bottle contacts the extrusion section 9 and press down. The extrusion section 9 is forced to drive the slider 5 to slide outward along the slide groove 8 (the spring 7 deforms). After the bottom of the bottle is completely placed on the anti-slip pad 24 of the fixing area 3, the spring 7 returns to its original position and drives the slider 5 to move towards the center. The clamping point 10 automatically clamps the bottle body to complete the fixing.
