[0051] The constant temperature device is an important experimental device and can be widely applied in laboratories and analysis rooms in multiple fields such as medicine and health, chemical industry, food industry, and metallurgical industry. It is mainly used to provide a water environment with a constant temperature to meet the temperature control requirements of various experiments.

[0052] The constant temperature device mostly uses an incubator to maintain a constant temperature. The incubator usually has a heat preservation tank for holding liquids. Experimental personnel can place items that need to be heat-preserved, such as test tubes and conical flasks, in the heat preservation tank. The incubator can heat or cool the liquid in the heat preservation tank, and the liquid exchanges heat with the items in the heat preservation tank to maintain the temperature of the items within a set range.

[0053] In the prior art, in order to place the reagent bottle in the heat preservation tank without shaking, an installation and fixing device is usually provided. However, the fixing effect of the installation and fixing device for fixing the reagent bottle is poor, and the installation and fixing device can only be sleeved on the outer side of the reagent bottle within a certain size range, which has more requirements for the size of the reagent bottle, has a small application range, and the installation and fixing device cannot adjust the height, so the fixing requirements for reagent bottles of different heights cannot be met.

[0054] Referring to Figures 1-4 , the present application provides an incubator 100 with good installation and fixing effect, applicable to more sizes and capable of fixing different reagent bottles.

[0055] Referring to Figure 1 , the incubator 100 includes a box body 1. The box body 1 includes a top surface of the box body 1 and a bottom surface of the box body 1 that are opposite to each other. A heat preservation tank 2 that is recessed toward the bottom surface is provided on the top surface of the box body 1. A liquid is contained in the heat preservation tank 2, and the item to be heat-preserved can be placed in the heat preservation tank 2.

[0056] The incubator 100 further includes an installation column 3 and an installation sleeve 4. The installation column 3 is connected to the top surface of the box body 1. The installation sleeve 4 is connected to the outer periphery of the installation column 3.

[0057] The number of the heat preservation tanks 2 is one or more. When there are no less than one heat preservation tanks 2, the multiple heat preservation tanks 2 are arranged in a circular array. The installation column 3 is arranged at the center of the circular array formed by the multiple heat preservation tanks 2 to facilitate the installation sleeve 4 connected to the installation column 3 to fix the reagent bottle.

[0058] The installation sleeve 4 is arranged above the heat preservation tank 2 and is used to be sleeved on the outer periphery of the reagent bottle to play a role in fixing the reagent bottle. One end of the installation sleeve 4 is connected to the installation column 3 and is fixed on the outer peripheral side of the installation column 3. When an object needs to be heat-preserved, the experimenter can fix the object inside the installation sleeve 4 and place the lower end of the object to be heat-preserved in the heat preservation tank 2. A heat preservation liquid is provided in the heat preservation tank 2, and the object to be heat-preserved exchanges heat with the heat preservation liquid so that the temperature of the object to be heat-preserved is maintained within the set range.

[0059] The installation column 3 includes a column body side surface on the outer periphery extending in the up and down direction.

[0060] In some embodiments, the installation column 3 is generally a cylindrical structure, and the column body side surface is a curved surface.

[0061] In some embodiments, the installation column 3 is generally a prismatic structure, and a plurality of planes are connected to form the column body side surface.

[0062] Referring to Figure 2 , a sliding track 31 extending in the up and down direction is provided on the column body side surface of the installation column 3. The installation sleeve 4 is slidably connected to the sliding track 31 so that the installation sleeve 4 can move up and down along the sliding track 31 to facilitate fixing reagent bottles of different heights.

[0063] In some embodiments, the sliding track 31 is a strip-shaped groove extending in the up-and-down direction. One end of the annular mounting sleeve 4 is provided with a protruding portion 41, and the protruding portion 41 is connected in the strip-shaped groove so that the fixing sleeve is limited by the strip-shaped groove, so that the fixing sleeve can only move up and down along the strip-shaped groove to define the movement path of the fixing sleeve and reduce the probability of the position deviation of the fixing sleeve after long-term use.

[0064] In some embodiments of the present application, the mounting post 3 is hollow inside and is provided with a mounting groove 32 extending in the up-and-down direction. A component for adjusting the up-and-down movement of the mounting sleeve 4 is installed inside the mounting groove 32.

[0065] The constant temperature box 100 includes a first rotating rod 33. The top of the mounting post 3 is provided with a hole. The first rotating rod 33 passes through the top of the mounting post 3 and extends into the mounting groove 32. The first rotating rod 33 extends in the up-and-down direction.

[0066] The constant temperature box 100 further includes a moving platform 34. The first rotating rod 33 is disposed through the center of the moving platform 34. When the first rotating rod 33 rotates along its axis, the moving platform 34 moves up and down.

[0067] In some embodiments, the first rotating rod 33 is provided with an external thread, and the center of the moving platform 34 is provided with a threaded hole. The first rotating rod 33 is threadedly connected to the moving platform 34 so that the rotation of the first rotating rod 33 drives the moving platform 34 to move up and down.

[0068] The constant temperature box 100 further includes a limiting plate 35. The limiting plate 35 is disposed around the outer peripheral edge of the moving platform 34. A limiting protruding plate 351 is provided on the side surface of the limiting plate 35 facing the moving platform 34, and the upper top surface of the limiting protruding plate 351 is a first inclined surface 3511.

[0069] The outer peripheral side surface of the moving platform 34 is an outer inclined surface, and the outer inclined surface is disposed opposite to the first inclined surface 3511. In some embodiments, the moving platform 34 is a frustum of a cone, and the outer inclined surface is an inclined curved surface, so that the relative sliding between the moving platform 34 and the limiting protruding plate 351 is smoother.

[0070] When the moving platform 34 moves up and down, the outer peripheral side surface of the moving platform 34 and the first inclined surface 3511 of the limiting protruding plate 351 slide relative to each other, and the moving platform 34 and the limiting protruding plate 351 are in contact with each other, driving the limiting protruding plate 351 to move in and out. When the moving platform 34 is stationary, the outer peripheral side surface of the moving platform 34 and the first inclined surface 3511 are in contact with each other, so that the limiting plate 35 is fixed at a specific position.

[0071] The sliding track 31 is a strip-shaped groove extending in the up-and-down direction. One end of the annular mounting sleeve 4 is provided with a protruding portion 41, and the protruding portion 41 is connected in the strip-shaped groove.

[0072] Referring to Figure 2 and Figure 3 , the strip-shaped groove and the limiting plate 35 are oppositely arranged, and there is a first gap between the strip-shaped groove and the limiting plate 35. An extension baffle 411 is provided at the top of the protruding portion 41, and the extension baffle 411 is clamped in the first gap. When the limiting plate 35 moves outwards, the thickness of the first gap becomes smaller; when the limiting plate 35 moves inwards, the thickness of the first gap becomes larger.

[0073] When the thickness of the first gap is not greater than the thickness of the extension baffle 411, the extension baffle 411 is fixed in the first gap, so that the protruding portion 41 is fixedly connected to the mounting post 3.

[0074] The width of the extension baffle 411 is greater than the width of the strip-shaped groove, so that the extension baffle 411 is clamped between the limiting plate 35 and the inner side wall of the mounting post 3 and does not fall off outwards from the strip-shaped groove.

[0075] In some embodiments, the cross-section of the protruding portion 41 intercepted by a horizontal plane is T-shaped, so that the protruding portion 41 can be better fixed between the limiting plate 35 and the inner side wall of the mounting post 3.

[0076] When the limiting plate 35 is abutted by the moving platform 34 and moves outwards to a certain position, the protruding portion 41 is clamped between the limiting plate 35 and the inner side wall of the mounting post 3, so that the position of the protruding portion 41 is fixed, and thus the position of the mounting sleeve 4 is fixed. Therefore, the experimenter can rotate the first rotating rod 33 to move the moving platform 34 up and down to adjust the position of the limiting plate 35, so as to clamp or loosen the position of the protruding portion 41 and fix or move the position of the mounting sleeve 4.

[0077] The following details the steps for the experimenter to move and fix the mounting sleeve 4 in the up and down directions:

[0078] When the experimenter wants to change the height position of the mounting sleeve 4, the experimenter rotates the first rotating rod 33 in the first rotating direction to drive the moving platform 34 to move upwards. The radius of the contact point between the moving platform 34 and the limiting convex plate 351 becomes smaller, thereby driving the limiting plate 35 to contract inwards, so that the first gap between the outer side surface of the limiting plate 35 and the inner side wall of the mounting post 3 becomes larger. When the thickness of the first gap is greater than the thickness of the extension baffle 411 at the top of the protruding portion 41, the extension baffle 411 no longer receives the pressing force from the limiting plate 35, and the extension baffle 411 can move up and down freely, that is, the mounting sleeve 4 can move up and down freely to any position;

[0079] When the experimenter wants to fix the height position of the mounting sleeve 4, the experimenter rotates the first rotating rod 33 in the second rotating direction, which is opposite to the first rotating direction, to drive the moving platform 34 to move downward, so that the radius of the contact point between the moving platform 34 and the limiting convex plate 351 becomes larger, and the limiting plate 35 expands outward, so that the first gap between the outer side surface of the limiting plate 35 and the inner side wall of the mounting column 3 becomes smaller. When the thickness of the first gap is not less than the thickness of the extending baffle 411, the extending baffle 411 is pressed by the limiting plate 35 and is fixed in the first gap, so that the mounting sleeve 4 is fixed at the required height position.

[0080] In some embodiments, a spring 36 is provided inside the mounting column 3. Opposite mounting holes are provided at the top and bottom inside the mounting column 3. The top and bottom ends of the limiting plate 35 are respectively arranged in the mounting holes. The spring 36 is arranged in the mounting holes and is located on the side of the limiting plate 35 close to the first rotating rod. The spring 36 gives an outward force to the limiting plate 35, so that the contact force between the limiting plate 35 and the protruding portion 41 is greater, and the protruding portion 41 is more stable when clamped.

[0081] In some embodiments, the limiting plates 35 and the mounting sleeves 4 are arranged in one-to-one correspondence. Each protruding portion 41 is respectively in contact with a limiting plate 35, so that the height position of each protruding portion 41 can be adjusted separately.

[0082] In some embodiments, there are multiple mounting sleeves 4, and the multiple mounting sleeves 4 are arranged at intervals to correspond to the multiple heat preservation grooves 2. The limiting plates 35 are arranged at intervals and are arranged in a circular array. The first rotating rod 33 is located at the center of the circular array formed by the limiting plates 35, so that the force on the moving platform 34 is more uniform when it contacts the limiting plate 35, and the probability of uneven force damage to the components is reduced.

[0083] In some embodiments, a positioning rod 37 extending up and down is provided inside the mounting column 3. A through hole is provided on the moving platform 34. The positioning rod 37 is inserted into the moving platform 34. When the moving platform 34 moves up and down, it needs to move along the positioning rod 37, so that the moving path of the moving platform 34 can be more fixed, and the probability of the position of the moving platform 34 shifting is reduced, so that the mounting sleeve 4 can be more firmly clamped.

[0084] Refer to Figure 4 , the mounting sleeve 4 includes a mounting ring 43 and a support ring 42. The support ring 42 is connected to the protruding portion 41 to realize the connection and fixation between the mounting sleeve 4 and the mounting column 3. The mounting ring 43 is located inside the support ring 42. The mounting ring 43 has a certain elasticity and is used to sleeved outside the reagent bottle to realize the clamping of the reagent bottle.

[0085] The mounting ring 43 includes a ring portion 431, a first extension plate 432, and a second extension plate 433. The first extension plate 432 and the second extension plate 433 are connected to the outer peripheral side of the ring portion 431 and extend in a direction away from the center of the ring portion 431 along the radial direction of the ring portion 431.

[0086] The first extension plate 432 is connected to the support ring 42 so that the mounting ring 43 is fixed inside the support ring 42, and thus the reagent bottle is fixed inside the support ring 42 by the mounting ring 43.

[0087] The second extension plate 433 is spaced apart from the first extension plate 432, and an angle is formed between the length direction of the first extension plate 432 and the length direction of the second extension plate 433. There is a certain gap between the second extension plate 433 and the inner side wall of the support ring 42 opposite thereto.

[0088] In some embodiments, the extension width of the first extension plate 432 in the up-down direction is not less than the extension width of the second extension plate 433 in the up-down direction, so that when the first extension plate 432 receives the supporting force of the support ring 42, it can more stably support the mounting ring 43 and reduce the probability of damage to the first extension plate 432.

[0089] The mounting sleeve 4 further includes an adjusting pressing plate 44. The adjusting pressing plate 44 has an outer adjusting plate 441, a first adjusting arm 442, and a second adjusting arm 443. The first adjusting arm 442 and the second adjusting arm 443 abut against the outer peripheral side of the mounting ring 43. When the positions of the first adjusting arm 442 and the second adjusting arm 443 change, the aperture of the mounting ring 43 is also adjusted accordingly, so that the mounting ring 43 can be adapted to reagent bottles of different sizes.

[0090] The outer adjusting plate 441 is connected between the first adjusting arm 442 and the second adjusting arm 443, and the outer adjusting plate 441 is located outside the support ring 42. There are holes provided on the outer adjusting plate 441, and the second rotating rod 45 is inserted through the holes. Rotating the second rotating rod 45 can adjust the position of the outer adjusting plate 441, so that the outer adjusting plate 441 transmits the pressing force to the first adjusting arm 442 and the second adjusting arm 443, thereby pressing the first adjusting arm 442 and the second adjusting arm 443 against the mounting ring 43, so that the mounting ring 43 clamps the outer wall of the reagent bottle, thus realizing the function of fixing the reagent bottle.

[0091] In some embodiments, the first adjusting arm 442 and the second adjusting arm 443 extend into the gap between the second extension plate 433 and the support ring 42, and the first adjusting arm 442 and the second adjusting arm 443 have top flanges that abut against the outside of the mounting ring 43 to adjust the inner diameter of the mounting ring 43 to adapt to reagent bottles of different sizes.

[0092] To make the abutting position between the top hem and the mounting ring 43 more accurate, the second extension plate 433 is usually arranged within the hem angle formed by the first adjusting arm 442 and the second adjusting arm 443, so that the top hem is limited by the second extension plate 433, thereby making the positional relationship between the top hem and the mounting ring 43 more stable. After long-term use, the first adjusting arm 442 and the second adjusting arm 443 can also be pressed against the outer side of the mounting ring 43.

[0093] In some embodiments, the included angle between the length direction of the first extension plate 432 and the length direction of the second extension plate 433 is 90°, so that the mounting ring 43 can more conveniently cooperate with the installation of the adjusting pressing plate 44.

[0094] In some embodiments, there are two mounting rings 43 arranged one above the other. It should be noted that the first extension plates 432 of the two mounting rings 43 are arranged opposite to each other up and down, and the second extension plates 433 of the two mounting rings 43 are arranged staggeredly up and down, so that the second extension plates 433 of the two mounting rings 43 are respectively arranged at the hems of the two adjusting arms, so as to play a role in installing and positioning the first adjusting arm 442 and the second adjusting arm 443.

[0095] In some embodiments, a plurality of rubber pads 4311 can be arranged at intervals on the inner surface of the ring part 431, and the plurality of rubber pads 4311 are annularly distributed around the central axis of the mounting ring 43. In this way, damage to the reagent bottle can be avoided when fixing the reagent bottle, ensuring the smooth progress of the experiment.

[0096] In some embodiments, the hole on the outer adjusting plate 441 is a threaded hole, and the second rotating rod 45 is a threaded rod, and the two are threadedly connected. By rotating the second rotating rod 45, the inner and outer movement of the outer adjusting plate 441 can be realized, so that the two adjusting arms are pressed against the outer peripheral side of the mounting ring 43, and the size of the mounting ring 43 can be changed according to the size of the reagent bottle.

[0097] In some embodiments, the connection between the mounting ring 43 and the support ring 42 is detachable, and the experimenter can take out the mounting ring 43 to facilitate the replacement of the reagent bottle.

[0098] The low temperature of this device can reach as low as -20°C. To avoid the liquid in the heat preservation tank 2 freezing at low temperature, the liquid in the heat preservation tank 2 is a mixture of water and a certain amount of propylene glycol. Propylene glycol is a non-toxic and non-evaporative antifreeze, which can effectively reduce the freezing point of the liquid in the heat preservation tank 2 and reduce the probability of the reagent bottle being frozen in the heat preservation tank 2.

[0099] The material of the heat preservation tank 2 is stainless steel, which can reduce the probability of rust of the heat preservation tank 2.

[0100] Above the heat preservation tank 2, there is a transparent quartz cover. The quartz cover matches the size of the circular card slot. The center of the quartz cover is provided with a hole having the same size as the mounting ring 43, so that the reagent bottle can pass through the hole on the surface of the quartz cover, facilitating the removal of the reagent bottle. The quartz cover can block dust in the environment, and the experimenter can observe the liquid change in the heat preservation tank 2 through the transparent quartz cover.

[0101] The constant temperature incubator 100 includes a temperature control box, an electric heating tube and a connecting wire respectively connected to each heat preservation tank 2. It should be noted that one heat preservation tank 2 is correspondingly connected to one temperature control box and one electric heating tube, so that each heat preservation tank 2 can be independently temperature-controlled.

[0102] In some embodiments of the present application, the constant temperature incubator 100 includes a control panel 5. One heat preservation tank 2 corresponds to one control panel 5. The control panel 5 is connected to the temperature control box, the electric heating tube and the temperature sensor, so that the experimenter can operate one control panel 5 to independently control a specific heat preservation tank 2. The temperature control box, the electric heating tube and the temperature sensor are all prior arts and are not shown in the figure. They can be arranged at appropriate positions inside the box body 1, and the present application will not elaborate on them.

[0103] The box body 1 of the constant temperature incubator 100 has a side surface. The side surface of the box body 1 extends in the up and down direction. The control panel 5 is arranged on the side surface of the box body 1 to facilitate the experimenter to observe and access the control panel 5.

[0104] The control panel 5 includes a status display screen and a start switch, and can independently control the temperature in the heat preservation tank 2.

[0105] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claimed rights.
