Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, and in particular to a beaker heating support. Background Technology

[0002] In chemical, biological, or medical laboratories, many reactions are endothermic and usually require heating to promote the reaction and control its progress. When heating, the substance to be heated is usually placed in a container, which is then placed on a heat source. Some containers, such as glass and ceramic containers, if placed directly on a heat source, often crack due to uneven heating and rapid temperature rise, or they may experience uneven heating of the substance due to poor heat transfer.

[0003] Therefore, heating containers entering the laboratory should undergo a heat bath treatment. A heat bath involves placing the container in a heat bath substance, allowing the temperature of the heat bath substance to rise slowly to a certain level, and then allowing it to cool slowly, thereby improving the heat transfer performance of the container and ensuring that the container is heated evenly. Commonly used heat bath methods in laboratories include water baths, oil baths, and air baths. Water baths and oil baths offer uniform temperature rise, but they require supervision to prevent dry burning, especially when using high-temperature oil as the heating medium. If used frequently, the oil is prone to clumping, necessitating oil replacement and increasing costs. Air baths, on the other hand, do not have the problems associated with water baths and oil baths, and they offer high operating temperatures and uniform heating, thus gaining widespread application. Furthermore, these heating methods typically require a heating sleeve to hold the heat bath material, which is placed on the heat source. A separate support with clamps is also needed to fix and support the container, ensuring it is stably placed within the heat bath material and preventing direct contact between the container's outer surface and the inner wall of the heating sleeve. This makes the components for heat bath treatment overly cumbersome, and different types of clamps are required for different shaped beakers, such as conical flasks and cylindrical flasks.

[0024] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0025] Example 1

[0026] like Figure 1-4 As shown, this embodiment 1 provides a beaker heating bracket that is compatible with beakers of different sizes for air bath heating. The beaker 000 of this utility model includes conical flasks, cylindrical flasks, spherical flasks, etc.

[0027] The beaker heating support in this embodiment 1 includes a base 100, the bottom surface of which is mounted on the heating end of the heater. The shape of the base 100 is not particularly limited; it can be rectangular, circular, polygonal, etc. In this invention, the base is a rectangular base.

[0028] A support body 200 is connected to the top surface of the base 100. In this embodiment 1, the base 100 and the support body 200 can be integrally formed or detachably connected. In this embodiment 1, the support body 200 is cylindrical and has an upward-opening hemispherical receiving chamber 201. To facilitate heat transfer from the heater, both the base and the support body are made of metal or metal alloy materials, such as aluminum or steel.

[0029] When the bracket body 200 and the base are detachably connected, in order to prevent the bracket body 201 and the base 100 from shifting relative to the heater, the bottom surface of the bracket body 200 is provided with four locking grooves 203 at intervals and equal distances; the top surface of the base 100 is provided with four grippers 101 at intervals, each gripper 101 has a right-angle locking part similar to a C-shape, the right-angle locking part of each gripper 101 is engaged with the four sides of the base 100, and the top surface of each gripper 101 is engaged in the locking groove 203.

[0030] Furthermore, to ensure that beakers of different diameters can be stably placed within the receiving chamber, a floating support is provided on the inner wall of the receiving chamber. In this embodiment 1, the floating support includes three sets of support members, each set of support members including an annular protrusion 202, and each annular protrusion 202 protrudes in a direction away from the bottom surface of the receiving chamber.

[0031] The three annular protrusions 202 are coaxially arranged and spaced apart around the central axis of the receiving chamber 201, with a groove between two adjacent annular protrusions 202. The diameters of the three annular protrusions 202 gradually increase along the direction away from the central axis of the receiving chamber 201, that is, the annular protrusion closest to the central axis of the receiving chamber 201 has the smallest diameter, and the annular protrusion farthest from the central axis of the receiving chamber 201 has the largest diameter. Furthermore, the heights of the top surfaces of the three annular protrusions 202 relative to the bottom surface of the inner wall of the receiving chamber 201 are also different, and the heights of the top surfaces of the three annular protrusions 202 relative to the bottom surface of the inner wall of the receiving chamber gradually increase along the central axis of the receiving chamber.

[0032] The annular protrusion 202 can be integrally formed with the receiving chamber, or it can be made separately by welding or other means.

[0033] Furthermore, to reduce the contact area between the annular protrusion and the beaker, the cross-section of each annular protrusion 202 is trapezoidal, that is, the bottom area of ​​each annular protrusion in contact with the inner wall of the receiving chamber 201 is the largest, and its top area away from the inner wall of the receiving chamber is the smallest.

[0034] Preferably, the top surface of each annular protrusion 202 is an arc shape.

[0035] Preferably, each annular protrusion 202 is circular.

[0036] During heating, the bottom of beakers of different sizes is placed on the top surface of the annular protrusions corresponding to their size to form support. When the beaker is a spherical bottle, the three-dimensional groove formed by the three annular protrusions together wraps around and fixes the spherical bottle.

[0037] Example 2

[0038] The difference between Example 2 and Example 1 is that there is no base 100 and the gripper 101 on the base, but everything else is the same. When in use, the bottom surface of the bracket body 200 is placed on the heating end of the heater.

[0039] Example 3

[0040] The difference between Example 3 and Example 1 is that the number and shape of the protrusions in each set of support members are different, while the rest are the same. The similarities between the two will not be described here.

[0041] The specific differences between the two include: In embodiment 3, the floating receiving part includes three sets of support members, each set of support members includes three protrusions, each protrusion is an arc-shaped protrusion, and the opening of each arc-shaped protrusion faces the central axis of the receiving chamber; the three arc-shaped protrusions in each set of support members are on the same horizontal plane and are equidistantly spaced.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
