Description

Technical Field

[0001] The utility model relates to the field of biochemical experimental equipment, in particular to an oscillation platform of a constant temperature oscillator. Background Art

[0002] Thermo-Shaker is a device widely used in scientific research, engineering fields and laboratories, mainly used for sample mixing, oscillation and constant temperature control.

[0003] The oscillation platform of an existing constant-temperature oscillator includes a support plate, multiple connecting plates at both ends of the support plate connected to the oscillation mechanism, and a fixing frame located on the connecting plate and above the support plate for securing the sample. The fixing frame includes a frame and a plurality of stainless steel springs arranged longitudinally and transversely within the frame. During use, the sample is placed in a test tube or conical flask, and the stainless steel springs on the fixing frame need to be manually pried apart to place the sample on the support plate. Existing constant-temperature oscillator oscillation platforms have the following drawbacks:

[0004] 1. The operation is inconvenient, especially for larger flasks, which need to be opened by hand to put them in;

[0005] 2. The clamping is unreliable, especially for test tubes. Since the bottom is round, it relies entirely on stainless steel springs to clamp the upper part. During the oscillation process, problems such as collisions between test tubes and sample spillage may occur.

[0006] Based on this, the present application provides an oscillation platform for a constant temperature oscillator that is easy to operate and has reliable clamping to solve the above problems. Utility Model Content

[0008] The technical solution adopted by the utility model to solve its technical problems is:

[0009] Provided is an oscillation platform for a constant temperature oscillator, comprising a supporting plate, a plurality of connecting plates arranged at both ends of the supporting plate and connected to an oscillation mechanism, and a fixing frame arranged on the connecting plate and located above the supporting plate for fixing a sample, wherein the fixing frame comprises a frame and a plurality of stainless steel springs arrayed longitudinally and transversely in the frame; one end of the fixing frame is hinged to the connecting plate, and the other end is provided with a plurality of elastic rubber pads that are pressed against the connecting plate; an overhead plate is also provided on the supporting plate, wherein a plurality of through holes are provided on the overhead plate for the samples to pass through, and an elastic sleeve is provided on the bottom surface of the overhead plate at each through hole, wherein the inner diameter of the elastic sleeve decreases from top to bottom.

[0011] In some optional embodiments, the through hole includes a first through hole matched with the outer diameter of the test tube and a second through hole matched with the maximum outer diameter of the flask.

[0012] In some optional embodiments, the elastic sleeve is a thin-walled sleeve made of rubber or silicone material, and its length is less than the distance between the overhead plate and the supporting plate.

[0013] In some optional embodiments, the elastic sleeve and the overhead plate are bonded or welded or fixed with a compression ring and screws.

[0014] In some optional embodiments, a limiting block is further provided on the connecting plate away from the hinged end of the fixing frame.

[0015] In some optional embodiments, a handle is further provided on the fixing frame at a middle portion away from the hinged end thereof.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The utility model hinges the fixing frame to the connecting plate, realizing the flip-up opening of the fixing frame, which is convenient for placing larger flasks. After placing, when closing the fixing frame, it is only necessary to push the stainless steel spring at the flask (the diameter of the flask mouth is smaller than the bottom diameter), which reduces the difficulty of placement.

[0018] 2. An overhead plate with through holes is provided on the supporting plate to limit the test tubes and flasks. At the same time, an elastic sleeve is provided at each through hole of the overhead plate to cover the test tubes or flasks and fix the bottom of the test tubes or flasks.

[0029] Example 1

[0030] This embodiment provides an oscillation platform of a constant temperature oscillator, as shown in the attached Figure 1 As shown, it comprises a support plate 1, a plurality of connecting plates 2 disposed at both ends of the support plate 1 and connected to an oscillating mechanism 10, and a fixing frame 3 disposed on the connecting plates 2 and above the support plate 1 for securing the sample. Four connecting plates 2 are generally provided, one on each side of the support plate 1; the support plate 1 is generally a porous plate; the fixing frame 3 comprises a frame 3.1 and a plurality of stainless steel springs 3.2 arranged longitudinally and transversely within the frame. The stainless steel springs can be arranged in a single layer or in two layers, one above the other.

[0031] In order to solve the problem of having to manually pry open a large opening with a stainless steel spring when placing a large flask, this embodiment hinges one end of the fixing frame 3 to the connecting plate 2, and the other end is provided with multiple elastic rubber pads 3.4 that are pressed against the connecting plate 2. Specifically, a hinged ear plate 3.3 is provided at one end of the fixing frame 3 relative to the two connecting plates 2, and a hinged seat 4 is provided on the connecting plate 2 to be hinged to the hinged ear plate 3.1. The hinged seat 4 is rotatably connected to the hinged ear plate 3.3 via a pin, thereby achieving the hinged connection of the fixing frame to the connecting plate. This structure allows the fixing frame to be flipped open, and the open state is as shown in the attached figure. Figure 2 As shown, the elastic rubber pad 3.4 at the other end of the fixing frame 3 can be squeezed with the connecting plate 2, so that the fixing frame is clamped when it is closed.

[0032] Preferably, a handle 3.5 is further provided on the fixing frame 3 at a middle portion away from the hinged end thereof, so as to facilitate manual pulling up of the fixing frame.

[0033] Preferably, a limit block 5 is further provided on the connecting plate 2 away from the hinged end of the fixing frame 3, and the limit block plays a limiting role for keeping the fixing frame in a horizontal state.

[0034] In order to improve the stability and reliability of clamping, this embodiment further provides an overhead plate 6 on the support plate 1. The overhead plate 6 is provided with a plurality of through holes 6.1 for samples to pass through. The through holes 6.1 include a first through hole 6.1a that matches the outer diameter of the test tube and a second through hole 6.1b that matches the maximum outer diameter of the flask. Furthermore, the bottom surface of the overhead plate 6 is provided with an elastic sleeve 7 at each through hole 6.1. The inner diameter of the elastic sleeve 7 decreases from top to bottom. This design allows the test tube or flask to pass through the first through hole or the second through hole and be placed on the support plate. The elastic sleeve can be used to clamp the bottom of the test tube or flask to fix the bottom of the test tube or flask. Combined with the clamping of the fixing frame, the reliability and stability of the clamping are ensured. This design not only meets the requirements for stable clamping of conical-bottom flasks, but also meets the requirements for stable clamping of round-bottom flasks.

[0035] Preferably, the elastic sleeve 7 is a thin-walled sleeve made of rubber or silicone material, and its length is smaller than the distance between the overhead plate 6 and the supporting plate 1 .

[0036] Preferably, the elastic sleeve 7 and the overhead plate 6 are bonded or welded or fixed with a pressure ring and screws.
