Description

Technical Field

[0001] The utility model relates to the technical field of analyzer protection, and more specifically to a surface protection device for a TPS thermal constant analyzer. Background Art

[0002] The TPS Thermal Constant Analyzer is an instrument used to measure the thermophysical properties of materials. Based on transient planar heat source technology, it can quickly and accurately measure thermal conductivity, thermal diffusivity, and specific heat. This instrument is suitable for a wide range of materials, including but not limited to metals, alloys, ceramics, ores, and composites. It offers advantages such as a wide range of test options, diverse test modules, and flexible test conditions.

[0003] Based on the above, the inventors found that the existing thermal constant analyzer is mainly composed of an analyzer body and a sample holder. The sample is fixed and tested by the sample holder. During the analysis process, the sample holder will emit high-temperature heat. Therefore, a protective cover is installed on the outside of the holder. However, the protective cover will also heat up due to the high temperature. After the analysis work is completed, it is not easy to remove it directly, which affects the working efficiency of the analyzer. Therefore, in view of this, the existing structure is studied and improved, and a surface protection device for a TPS thermal constant analyzer is provided, in order to achieve a more practical purpose. Utility Model Content

In addition, a self-locking card connection component is provided to improve the installation stability of the protective cover, reduce the occurrence of the protective cover shaking problem, and ensure the protection effect.

[0006] 2. Technical solution

[0007] In order to solve the above problems, the present invention adopts the following technical solutions.

[0008] A surface protection device for a TPS thermal constant analyzer comprises an analyzer body and a sample holder. The sample holder is sheathed with a protective cover. The top surface of the protective cover is provided with a handle, and the bottom surface of the protective cover is provided with a set of self-locking mechanisms. The top of the protective cover is provided with a sliding groove, the bottom of the sliding groove is provided with a connecting groove, and the bottom end of the handle is fixedly connected to a connecting block.

[0009] The self-locking mechanism includes a clamping plate, a pressure groove is provided in the center of the inner side of the clamping plate, a guide rod is provided on one side of the pressure groove, one end of the guide rod is movably connected to a movable ball, and the other end of the guide rod is sleeved with a self-locking spring.

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] (1) This solution rotates the connecting block by a handle. When the connecting block is aligned with the sliding groove, the handle can be pulled upward to separate the connecting block from the protective cover, thereby preventing the heat of the protective cover from being transferred to the connecting block. Conversely, the handle can be rotated to intersect the connecting block with the sliding groove, and then the handle can be pulled upward to separate the protective cover from the sample holder. Compared with the existing technology, a pick-up piece that is convenient for loading and unloading is provided to prevent the heat generated during the analysis from affecting the pick-up piece, thereby facilitating the timely removal of the protective cover at a later stage and improving the efficiency of sample analysis.

[0019] (2) By setting a self-locking mechanism, when the protective cover is installed, the clamping plate enters the interior of the sample holder to squeeze the movable ball, and the movable ball rotates under the force, and drives the guide rod to slide to one side until the pressure groove is aligned with the movable ball. Under the action of the self-locking spring, the guide rod drives the movable ball to reset, and the movable ball is clamped with the pressure groove to form a self-locking structure for the clamping plate. Compared with the existing technology, the provision of a self-locking clamping assembly improves the installation stability of the protective cover, reduces the occurrence of the protective cover shaking problem, and ensures the protection effect.
