Description

Technical Field

[0001] This utility model relates to the field of biochemical shaker technology, and in particular to a laboratory shaker. Background Technology

[0002] A biological shaker is a laboratory device widely used in biomedical research, especially in experiments requiring control of temperature and oscillation frequency.

[0003] Existing shakers, in order to seal the test tubes contained inside, often have a special cover plate on the lid that is pushed and slid closed by a spring. When the sealing cover plate flips down and closes with the lid, its rear part will first press against and come into contact with the test tube at the rear of the shaker. At this time, the rear part of the sealing cover plate will be subjected to the counter-pushing pressure of the test tube at the rear. This counter-pushing pressure biased on the rear part of the sealing cover plate will cause the sealing cover plate to slide and get stuck, so that the sealing cover plate cannot slide upward under the counter-pushing of the test tube at the rear to relieve the downward pushing pressure on the test tube at the rear, which can easily break the test tube at the rear. Utility Model Content

[0004] In view of this, the present invention provides a laboratory shaker to solve the problem that the sealing cover is prone to crushing the test tubes on the rear side when it is closed by flipping the bed cover.

[0005] The technical solution proposed by this utility model is: a laboratory shaker, specifically including a box-type shaker, wherein a horizontally supported test tube insertion plate is welded at the middle height position of the internal space of the box-type shaker, and a number of test tubes are evenly inserted through the test tube insertion plate, with the bottom side of the test tubes abutting against the bottom plate of the box-type shaker.

[0006] The top opening of the box-type shaker is rotatably covered by a box cover. The box cover has a U-shaped cross-section and a sealing plate is movably installed inside. Two L-shaped connecting rods are symmetrically rotatably connected to the middle of the two short sides of the top of the sealing plate. Two I-beam mounting brackets are symmetrically welded to the two short sides of the bottom of the top plate of the box-type shaker. The vertical sections of the two L-shaped connecting rods are pushed by springs and slide through the longitudinal support connecting rods of the two I-beam mounting brackets. The sealing plate protrudes from the box cover, and when the box cover is flipped down and closed, the sealing plate presses against and seals the top opening of the test tube.

[0007] Furthermore,

[0008] A rubber sealing gasket is adhered to the bottom side of the sealing plate. When the sealing plate is pressed and sealed onto the top opening of the test tube, the rubber sealing gasket is squeezed and comes into contact with the top opening of the test tube.

[0009] Furthermore,

[0010] The vertical side rods of the I-beam mounting bracket maintain a 2cm gap with the sealing plate.

[0011] Furthermore,

[0012] It also includes a convex support frame, with two convex support frames symmetrically arranged. Two cross bracing track shafts are symmetrically welded between the top parts of the two convex support frames, and the box-type rocker is slidably installed on the two cross bracing track shafts.

[0013] Furthermore,

[0014] A motor is suspended at the top of one of the convex support frames by screws. A drive wheel is fitted at the top of the motor shaft, and a connecting rod is rotatably connected to the outer circumference of the drive wheel.

[0015] Furthermore,

[0016] The first end of the connecting rod is rotatably connected to the base plate of the box-type shaking table.

[0017] Furthermore,

[0018] Four ear-shaped sliders are symmetrically welded and hoisted on the two short sides of the bottom plate of the box-type shaking table. The ear-shaped sliders slide in cooperation with the two cross brace track shafts.

[0019] The laboratory shaker provided by this utility model has the following beneficial effects:

[0020] 1. The sealing plate is rotatably connected to the box cover through two L-shaped connecting rods. During the process of the box cover flipping down and closing, when the rear part first comes into contact with the test tube at the rear position in the box shaker, the rear part can be pushed upward by the test tube at the rear to open up the gap, thus relieving the downward pressure on the test tube at the rear. Compared with the existing technology, this avoids the test tube at the rear position from being crushed by the pressure and can provide anti-breakage protection for the test tube at the rear position.

[0021] Second, since the sealing plate protrudes from the lid, when the lid flips down to close and causes the sealing plate to press against the top opening of the test tube, the test tube will push back, causing the sealing plate to slide upward as a whole. The cm distance between the vertical side rod of the I-beam mounting bracket and the sealing plate can provide the sealing plate with the margin to slide upward, ensuring the normal and effective implementation of the sealing plate's pressure sealing function on the test tube.

[0022] 3. When the lid is in the open position, the sealing plate inside loses the reverse push limit of the test tube and is in a free swinging state. The 2cm gap between the vertical side rod of the I-beam mounting bracket and the sealing plate is small, which allows the I-beam mounting bracket to block and limit the freely swinging sealing plate through its four vertical side rods, limiting the swinging range of the sealing plate and preventing the sealing plate from swinging out of the lid too much. During the process of the lid quickly falling down and closing, when the sealing plate is close to the test tube, the lid cannot slow down in time to cause the sealing plate to swing out too much and break the test tube.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this 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, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0038] Please refer to Figures 1 to 5 ;

[0039] Example 1:

[0040] This utility model proposes a laboratory shaker, including a box-type shaker 2. A horizontally supported test tube insertion plate 204 is welded at the middle height position of the internal space of the box-type shaker 2. Several test tubes 4 are evenly inserted through the test tube insertion plate 204, and the bottom side of the test tubes 4 abuts against the bottom plate of the box-type shaker 2.

[0041] The top opening of the box-type shaking table 2 is covered by a rotating cover 201. The cover 201 has a U-shaped cross-section and a sealing plate 203 is movably installed inside. Two L-shaped connecting rods 2031 are symmetrically and rotatably connected to the middle of the two short sides of the top of the sealing plate 203. Two I-beam mounting brackets 2011 are symmetrically welded to the two short sides of the bottom of the top plate of the box-type shaking table 2. The vertical sections of the two L-shaped connecting rods 2031 are pushed by springs to correspond to the two I-beam mounting brackets. The longitudinal support connecting rod of 2011 slides through; the sealing plate 203 protrudes from the box cover 201, and when the box cover 201 is flipped down to close, the sealing plate 203 presses against the top opening of the test tube 4, which can seal all the test tubes 4 and prevent the biological culture medium contained in the test tubes 4 from being shaken and spilled when the test tubes 4 slide left and right with the box shaker 2. The sealing plate 203 presses and seals the test tubes 4 by the downward pushing force applied by the springs on the two L-shaped connecting rods 2031.

[0042] The sealing plate 203 is rotatably connected to the box cover 201 through two L-shaped connecting rods 2031. During the process of the box cover 201 flipping down to close, when the rear part first comes into contact with the test tube 4 at the rear position in the box-type shaker 2, the rear part can be pushed upward by the test tube 4 at the rear position to open up the gap, thereby relieving the downward pressure on the test tube 4 at the rear position. Compared with the prior art, this avoids the test tube 4 at the rear position from being crushed by the pressure, and can provide anti-breakage protection for the test tube 4 at the rear position.

[0043] Preferred,

[0044] A rubber sealing gasket is adhered to the bottom side of the sealing plate 203. When the sealing plate 203 is pressed and sealed on the top opening of the test tube 4, the rubber sealing gasket is squeezed and comes into contact with the top opening of the test tube 4.

[0045] Preferred,

[0046] There is a 2cm gap between the vertical side bar of the I-beam mounting bracket 2011 and the sealing plate 203;

[0047] Because the sealing plate 203 protrudes from the lid 201, when the lid 201 flips down to close, causing the sealing plate 203 to press against the top opening of the test tube 4, the test tube 4 will push back, causing the sealing plate 203 to slide upwards. The 2cm gap between the vertical side rod of the I-beam mounting bracket 2011 and the sealing plate 203 provides sufficient clearance for the sealing plate 203 to slide upwards, ensuring the normal and effective implementation of the sealing function of the sealing plate 203 pressing against the test tube 4. When the lid 201 is in the flip-open state, the sealing plate 203 located therein loses the push-back limitation of the test tube 4. The I-beam mounting bracket 2011 is in a freely swinging state. The 2cm gap between the vertical side rods of the I-beam mounting bracket 2011 and the sealing plate 203 is small. This allows the I-beam mounting bracket 2011 to block and limit the freely swinging sealing plate 203 through its four vertical side rods, limiting the swing amplitude of the sealing plate 203 and preventing the sealing plate 203 from swinging out of the box cover 201 too much. During the process of the box cover 201 quickly flipping down and closing, when the sealing plate 203 approaches the test tube 4, the box cover 201 will have difficulty slowing down in time to cause the sealing plate 203 to swing out too much and break the test tube 4.

[0048] Based on Example 1, Example 2:

[0049] A laboratory shaker also includes a convex support frame 1, which is symmetrically arranged in two places. Two cross bracing track shafts 101 are symmetrically welded between the top parts of the two convex support frames 1. The box-type shaker 2 is slidably installed on the two cross bracing track shafts 101.

[0050] Preferred,

[0051] A motor 3 is suspended at the top of a convex support frame 1 by screws. A drive wheel 301 is fitted at the top of the shaft of the motor 3. A connecting rod 302 is rotatably connected to the outer circumference of the drive wheel 301. The first end of the connecting rod 302 is rotatably connected to the bottom plate of the box-type shaking table 2.

[0052] The drive wheel 301, connecting rod 302 and box-type shaker 2 are connected to form a crank-slider mechanism. Through this mechanism, the motor 3 and drive wheel 301 can rotate to drive the box-type shaker 2 to slide back and forth along the two horizontal support track shafts 101 to shake and mix the biological culture medium in the test tube 4.

[0053] Preferred,

[0054] Four ear-shaped sliders 202 are symmetrically welded and hoisted on the two short sides of the bottom plate of the box-type shaking table 2. The ear-shaped sliders 202 slide in cooperation with the cross support track shaft 101.

[0055] The working principle of this embodiment is as follows: the sealing plate 203 protrudes from the box cover 201, and when the box cover 201 is flipped down and closed, the sealing plate 203 presses and seals the top opening of the test tube 4, which can seal all the test tubes 4 and prevent the biological culture medium contained in the test tubes 4 from being shaken and spilled when the test tubes 4 slide left and right with the box shaker 2. The sealing plate 203 presses and seals the test tubes 4 by the downward pushing force applied by the springs on the two L-shaped connecting rods 2031.

[0056] Because the sealing plate 203 protrudes from the lid 201, when the lid 201 flips down to close, causing the sealing plate 203 to press against the top opening of the test tube 4, the test tube 4 will push back, causing the sealing plate 203 to slide upwards. The 2cm gap between the vertical side rod of the I-beam mounting bracket 2011 and the sealing plate 203 provides sufficient space for the sealing plate 203 to slide upwards. When the lid 201 is in the flip-open state, the sealing plate 203, no longer restrained by the test tube 4, is in a freely rotatable state. The small 2cm gap between the vertical side rods of the I-shaped mounting bracket 2011 and the sealing plate 203 allows the I-shaped mounting bracket 2011 to block and limit the freely swinging sealing plate 203 through its four vertical side rods, limiting the swing amplitude of the sealing plate 203 and preventing the sealing plate 203 from swinging out of the box cover 201 too much. During the process of the box cover 201 quickly falling down and closing, when the sealing plate 203 approaches the test tube 4, the box cover 201 is unable to decelerate in time to cause the sealing plate 203 to swing out too much and break the test tube 4.

[0057] The drive wheel 301, connecting rod 302 and box-type shaker 2 are connected to form a crank-slider mechanism. Through this mechanism, the motor 3 and drive wheel 301 can rotate to drive the box-type shaker 2 to slide back and forth along the two horizontal support track shafts 101 to shake and mix the biological culture medium in the test tube 4.
