Description

Technical Field

[0001] This utility model relates to the field of biomedical instrument technology, and in particular to a double-layer tray rocker bed. Background Technology

[0002] The rocker shaker is a benchtop shaker that can be placed directly in a greenhouse or incubator. It is widely used for fixing various electrophoresis gels, shaking during Coomassie blue staining and destaining, and fixing, staining, and developing silver nitrate stains. It is compatible with various laboratory sample vials, such as petri dishes, Erlenmeyer flasks, and culture bottles.

[0003] Typically, a tray is set up on a rocker shaker to hold sample vials, and a clamping component is also set up on the tray to hold and fix the sample vials. However, the clamping component on the existing rocker shaker does not have adjustment capability and cannot be adapted to different types or shapes of sample vials. The clamping and fixing operation is quite troublesome, or the clamping is not firm enough, causing the sample vials to slide on the tray, increasing the risk of the sample vials slipping off the tray.

[0004] The purpose of this invention is to propose corresponding solutions to the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a double-layer tray rocker. This invention has an adjustable clamping device to clamp and fix the sample bottles on the tray, which can be adapted to sample bottles of different types and shapes.

[0006] The technical solution adopted by this utility model is as follows: a double-layer tray rocker bed, including a rocker bed and a tray disposed on the rocker bed. The tray is provided with at least two sets of clamping devices. Each set of clamping devices includes a tension spring and two fastening components. A baffle is provided at each end of the tray. The two ends of the tension spring are respectively connected to the baffle through a fastening component. Each baffle is also provided with a strip groove. The path of the strip groove is parallel to the tray. Each fastening component includes a fastener and an assembly. The fastener passes through the strip groove and is connected to the assembly. A first clamping part is formed between the tension spring and the tray. A second clamping part is formed between the two tension springs. When the fastener and the assembly respectively abut against the two sides of the baffle, the tension spring is fixed on the tray.

[0007] The end of the tension spring is hooked onto a fastener or assembly.

[0008] The tension spring is covered with an anti-slip sleeve, which extends along the torsional direction of the tension spring.

[0009] The clamping device also includes an adjusting component, which is disposed between the tension spring and the fastening assembly. The fastener is a bolt, and the fitting is a nut. The fastener is threadedly connected to the fitting, and one end of the fastener passing through the fitting extends into an extension section. The adjusting component is connected to the extension section via an internal thread, and the end of the tension spring is hooked onto the adjusting component.

[0010] The length of the extension section is greater than that of the adjusting member, and the adjusting member moves back and forth on the extension section by rotating the internal thread.

[0011] The rocker bed is equipped with two parallel trays, which are connected by two sets of side frames, and both trays are equipped with rubber anti-slip mats.

[0012] The side frame includes an upper support and a lower support, which are respectively installed on two trays. The upper support and the lower support are connected by a plug-in connection. The upper support is provided with a toggle piece and a spring. The lower support is provided with a plurality of locking holes for the toggle piece to be inserted. The plurality of locking holes are distributed in the vertical direction. The spring pushes the toggle piece to press towards the locking hole. When the toggle piece is inserted into one of the locking holes, the upper support and the lower support are fixedly connected.

[0013] The beneficial effects of this utility model are as follows: This utility model has an adjustable clamping device to clamp and fix sample bottles on a tray. With the cooperation of tension springs and sliding fastening components, the positions of the two tension springs on the tray can be flexibly adjusted according to the size and shape of the sample bottle to be fixed. It can firmly fix a single larger sample bottle through the first clamping part formed by a single tension spring and the tray, and can also clamp one or more smaller sample bottles together through the second clamping part formed by the cooperation of two tension springs. This greatly enhances the adaptability to various types and specifications of sample bottles in the laboratory, overcomes the defects of poor versatility of traditional fixed clamping components, and the elastic preload provided by the tension spring itself can adaptively tighten on sample bottles of different sizes to ensure firm clamping and effectively prevent sample bottles from slipping. The structure of the fasteners and the clamping baffle in combination with the assembly enables quick locking and releasing, making the operation convenient and labor-saving.

Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0019] like Figures 1 to 3 As shown, this is an embodiment of the present invention: a double-layer tray rocker bed, including a rocker bed 1 and a tray 2 disposed on the rocker bed 1. The tray 2 is provided with at least two sets of clamping devices. Each set of clamping devices includes a tension spring 3 and two fastening components. A baffle 4 is provided at each end of the tray 2. The two ends of the tension spring 3 are respectively connected to the baffle 4 through a fastening component. Each baffle 4 is also provided with a strip groove 5. The path of the strip groove 5 is parallel to the tray 2. Each fastening component includes a fastener 6 and an assembly 7. The fastener 6 passes through the strip groove 5 and is connected to the assembly 7. A first clamping part 8 is formed between the tension spring 3 and the tray 2, and a second clamping part 9 is formed between two tension springs 3. When the fastener 6 and the assembly 7 respectively abut against the two sides of the baffle 4, the tension spring 3 is fixed on the tray 2.

[0020] The beneficial effects of this design are as follows: This utility model has an adjustable clamping device to clamp and fix sample bottles on a tray. With the cooperation of tension springs and sliding fastening components, the positions of the two tension springs on the tray can be flexibly adjusted according to the size and shape of the sample bottle to be fixed. It can firmly fix a single larger sample bottle through the first clamping part formed by a single tension spring and the tray, and it can also clamp one or more smaller sample bottles together through the second clamping part formed by the cooperation of two tension springs. This greatly enhances the adaptability to various types and specifications of sample bottles in the laboratory, overcomes the shortcomings of poor versatility of traditional fixed clamping components, and the elastic preload provided by the tension spring itself can adaptively tighten on sample bottles of different sizes to ensure firm clamping and effectively prevent sample bottles from slipping. The structure of the fasteners and the clamping baffle in combination with the assembly enables quick locking and releasing, making the operation convenient and labor-saving.

[0021] Furthermore, the end of the tension spring 3 is hooked onto the fastener 6 or the fitting 7.

[0022] The advantages of this design are as follows: the end of the tension spring is directly hooked onto the fastener or assembly, eliminating the need for additional connecting parts and facilitating quick assembly and disassembly.

[0023] Furthermore, the tension spring 3 is covered with an anti-slip sleeve 10, which extends along the torsional direction of the tension spring 3.

[0024] The beneficial effects of this design are as follows: the anti-slip sleeve directly increases the friction between the tension spring and the sample vial, effectively preventing the sample vial from rotating or sliding axially during oscillation, especially on smooth glass or plastic surfaces, making the clamping and fixing more secure and reliable. It also prevents the metal tension spring from directly contacting the sample vial, preventing the tension spring from scratching or wearing the sample vial surface, and at the same time, it can prevent the reagent from corroding the tension spring. The anti-slip sleeve extends along the torsional direction of the tension spring, which not only ensures a secure fit, but also does not affect the extension and contraction of the tension spring.

[0025] Furthermore, the clamping device also includes an adjusting member 11, which is disposed between the tension spring 3 and the fastening assembly. The fastener 6 is a bolt, and the fitting 7 is a nut. The fastener 6 and the fitting 7 are threadedly connected. One end of the fastener 6 that passes through the fitting 7 extends into an extension section 12. The adjusting member 11 is connected to the extension section 12 via an internal thread 13. The end of the tension spring 3 is hooked onto the adjusting member 11.

[0026] The advantages of this design are as follows: the tension of the spring can be independently fine-tuned through the adjusting component, allowing for flexible adjustment to the most suitable clamping force. This ensures the stability of the clamping while preventing damage to the sample bottle due to excessive force. Furthermore, adjusting the adjusting component will not affect the fasteners and assemblies, i.e., bolts and nuts, eliminating the need for repeated tightening and loosening. The position and tension of the spring can be adjusted independently, improving the reliability and service life of the entire fastening assembly.

[0027] Furthermore, the length of the extension section 12 is greater than that of the adjusting member 11, and the adjusting member 11 moves back and forth on the extension section 12 by rotating the internal thread 13.

[0028] The beneficial effects of this design are as follows: the longer extension section provides ample travel space for the adjustment components, which in turn increases the adjustable range of the tension spring, improving versatility and flexibility.

[0029] In a further configuration, the rocker bed 1 is provided with two parallel trays 2, which are connected by two sets of side frames 14, and both trays 2 are provided with rubber anti-slip pads 15.

[0030] The beneficial effects of this setup are as follows: by setting up two parallel trays, the number of samples that a single device can simultaneously carry and vibrate is doubled, greatly improving the utilization rate of laboratory space and the efficiency of experimental work. The rubber anti-slip pads on each tray effectively increase the friction between the tray and the sample vials, preventing the sample vials from sliding, shifting, or tipping over during vibration. At the same time, the flexibility of the rubber pads plays a role in cushioning and shock absorption, protecting the delicate sample vials.

[0031] Further, the side frame 14 includes an upper support 16 and a lower support 17 respectively mounted on two trays 2. The upper support 16 and the lower support 17 are connected by a plug-in connection. The upper support 16 is provided with a toggle piece 18 and a spring 19. The lower support 17 is provided with a plurality of locking holes 20 for the toggle piece 18 to be inserted. The plurality of locking holes 20 are distributed in the vertical direction. The spring 19 pushes the toggle piece 18 to press towards the locking hole 20. When the toggle piece 18 is inserted into one of the locking holes 20, the upper support 16 and the lower support 17 are fixedly connected.

[0032] The beneficial effects of this design are as follows: Through the plug-in connection and spring-driven actuating plate and locking mechanism, the lock can be quickly released with a simple operation of the actuating plate, easily adjusting the vertical distance between the two trays. After adjustment, releasing the actuating plate will automatically relock the mechanism under the action of the spring. This design allows the shaker to flexibly adapt to sample containers of different heights, greatly improving the equipment's versatility and space utilization. The actuating plate is firmly embedded in the locking hole under continuous spring pressure, forming a reliable mechanical interlock, effectively preventing accidental loosening or slippage due to vibration during shaking operation. This ensures that the two trays remain stably connected in any adjustment position, guaranteeing smooth operation and experimental safety. This adjustment mechanism can be operated with one hand without any tools; the adjustment process is simple, fast, and intuitive, greatly simplifying experimental preparation and improving work efficiency. In this embodiment, the locking holes on both side frames are of the same height to ensure the stability of the upper tray.

[0033] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
