Technical Field

[0001] The utility model relates to the technical field of differential scanning calorimeters, in particular to a differential scanning calorimeter with a furnace chamber cover suspension mechanism. Background Art

[0002] The differential scanning calorimeter with a furnace cover suspension mechanism is an instrument that measures the heat of a sample as it changes with temperature or time under a set temperature control program. When in use, place the sample and reference sample (usually an empty crucible) into the furnace cavity from the furnace cavity opening to a position close to the sensor, cover the furnace cavity cover, and perform measurements using the corresponding program software. After the measurement is completed, take out the sample.

[0003] When opening the furnace cavity cover, due to the small size of the cover, it is usually necessary to use a clamping tool such as tweezers, and it is not possible to flexibly turn the cover upside down on the table to avoid contaminating the inner side of the cover, especially when there is an outer cover and an inner cover at the same time, which further increases the difficulty of opening the cover. Therefore, the utility model proposes a differential scanning calorimeter with a furnace cavity cover suspension mechanism. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figure 1-6 As shown, the utility model proposes a differential scanning calorimeter with a furnace chamber cover suspension mechanism, comprising an instrument housing 1 and an outer cover 2 and an inner cover 3 filled at the furnace chamber opening, wherein the inner cover 3 is located inside the furnace chamber opening, and the outer cover 2 is located at the opening of the furnace chamber opening.

[0031] In this embodiment, the differential scanning calorimeter includes a furnace chamber cover suspension mechanism 4 installed on the outer wall of the instrument housing 1 for suspending the outer cover 2 and the inner cover 3. The furnace chamber cover suspension mechanism 4 includes a suspension arm 41, a base 42, a slide rail 43, a support column 44 and a magnet sheet 45. Specifically:

[0032] The outer cover 2 and the inner cover 3 are both provided with a shaft handle with a dome structure. The suspension arm 41 is provided with a first suspension opening 411 for suspending the outer cover 2 and a second suspension opening 412 for suspending the inner cover 3. The dome structure is stuck at the narrow openings of the first suspension opening 411 and the second suspension opening 412 to prevent the outer cover 2 and the inner cover 3 from slipping off the suspension arm 41.

[0033] A pair of rotating shaft seats 421 are fixedly connected to the upper surface of the base 42, and a bottom roller 413 is fixedly connected to the bottom end of the suspension arm 41. Both ends of the bottom roller 413 are rotatably connected to the corresponding rotating shaft seats 421 through a rotating shaft.

[0034] The magnet sheet 45 is fixedly connected to the outer wall of the suspension arm 41, the bottom end of the support column 44 is fixedly connected to the upper surface of the base 42, and the top end is a dome structure that can be magnetically attracted to the magnet sheet 45. Figure 2 or Figure 3 In the tilted state shown, the support of the support column 44 can maintain stability, and the stability can be improved by the magnetic attraction between the magnet sheet 45 and the support column 44;

[0035] The slide rail 43 is fixedly connected to the upper surface of the instrument housing 1, and the base 42 is provided with a slide groove 422 that can slide horizontally with the slide rail 43. The two ends of the slide rail 43 are detachably fixedly connected with anti-slip end plates 431 to prevent the base 42 from slipping off by bolts, and because it is connected by bolts, the furnace cavity cover suspension mechanism 4 can be removed from the instrument housing 1 after removal, so that it is possible to choose whether to use the furnace cavity cover suspension mechanism 4 according to actual needs.

[0036] The working principle of this embodiment is: when measuring, first rotate the suspension arm 41 upward to Figure 2 or Figure 3 The tilted shape in Figure 4-5 The suspension arm 41 is supported by the support column 44 to keep the position limited. After opening the outer cover 2 and the inner cover 3, the dome-shaped shaft handles of the two can be respectively inserted into the first suspension opening 411 and the second suspension opening 412, and the outer cover 2 and the inner cover 3 are suspended on the suspension arm 41. Put the sample and the reference sample into the furnace cavity of the instrument housing 1 through the opened furnace cavity opening, and then remove the inner cover 3 and the outer cover 2 from the suspension arm 41 in turn and put them into the furnace cavity for measurement. When the device is idle, the suspension arm 41 can be rotated downward to Figure 1 The horizontal state shown not only reduces space occupation, but also makes it easier for the suspension arm 41 to break due to accidental collision when it is kept in a rotated and tilted state;

[0037] In this embodiment, when the operator stands in different positions to operate, the furnace chamber cover suspension mechanism 4 can be moved to a position that does not block the hands through horizontal sliding between the base 42 and the slide rail 43, thereby avoiding obstacles to the taking and placing of samples.

[0038] In summary, through the design of the furnace chamber cover suspension mechanism 4, the outer cover 2 and the inner cover 3 can be suspended at the first suspension opening 411 and the second suspension opening 412 respectively, which is not only convenient to operate but also can prevent pollution caused by placing them on the table; through the rotation connection design between the suspension arm 41 and the base 42, the suspension arm 41 can be rotated to a horizontal state after closing the cover to reduce space occupancy, and maintaining the rotated and tilted state is also prone to damage due to accidental collision; through the annular horizontal sliding design between the base 42 and the slide rail 43, the orientation of the furnace chamber cover suspension mechanism 4 relative to the furnace chamber opening can be adjusted accordingly according to the position of the personnel to avoid obstruction to the placement and removal of samples.

[0039] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
