TECHNICAL FIELD

[0001] The utility model relates to flash point instrument technical field especially automatic low temperature balance flash point instrument. BACKGROUND

[0002] The balance flash point instrument is an instrument for determining the flash point of liquid fuel, lubricating oil and other substances. The flash point refers to the lowest temperature at which the liquid surface can produce flash combustion under specified test conditions. The balance flash point instrument has important application value in the petrochemical industry, transportation, power and other industries. It can help enterprises detect the quality of products and ensure that the products meet relevant standards and safety requirements. At the same time, the balance flash point instrument also provides an important experimental means for scientific research, which helps to understand the combustion characteristics and safety of substances.

[0003] In the actual experimental operation process, the balance flash point instrument of the prior art has some shortcomings. When performing flash point testing, during the experiment, when the material burns, a large impact force is generated, which makes the container prone to shaking. For example, in some traditional balance flash point instruments, the container is simply placed on the instrument without a special limiting device to fix the position of the container. In this way, when the material burns violently, the shaking of the container will affect the accuracy and stability of the experiment, and even cause the experiment to fail, so the technical field proposes an automatic low temperature balance flash point instrument to solve the above problems. CONTENT OF THE UTILITY MODEL

[0004] In order to make up for the above shortcomings, the utility model provides an automatic low temperature balance flash point instrument, which aims to improve the problem that the flash point instrument of the prior art is prone to violent burning of materials during the experiment, which causes the container to shake and affects the experimental effect.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: an automatic low temperature balance flash point instrument, comprising a flash point instrument body and an unlocking assembly, the unlocking assembly is arranged in the interior of the flash point instrument body, a disc cover is arranged in the top groove of the flash point instrument body, a lighter is installed on the top of the flash point instrument body, a stable assembly is arranged on the top of the flash point instrument body, and the stable assembly is used to keep the state of the disc cover stable during the experiment.

[0006] The stable assembly comprises a mounting groove, the bottom of the mounting groove is fixedly connected to the top of the flash point instrument body, a fixed rod is fixedly connected to the inner side of the mounting groove, a spring one is sleeved on the outer side of the fixed rod, an L-shaped limiting block is slidably connected to the outer side of the fixed rod, an L-shaped shifting block is fixedly connected to the outer side of the L-shaped limiting block, a clamping hole is formed in the inner side of the L-shaped shifting block, an L-shaped rotating plate is rotatably connected to the outer side of the mounting groove, and a clamping block is fixedly connected to the outer side of the L-shaped rotating plate.

[0007] Furthermore, the outer side of the L-shaped limiting block is fitted to the top of the disc cover, and the outer side of the L-shaped limiting block is slidably connected to the inner side of the mounting groove.

[0008] Furthermore, one end of the spring is fixedly connected to the outer side of the L-shaped limiting block, and the other end of the spring is fixedly connected to the inner side of the mounting groove.

[0009] Furthermore, the outer side of the L-shaped rotating plate is fitted with the outer side of the L-shaped lever, and the outer side of the locking block is fitted with the inner side of the locking hole.

[0010] Furthermore, the unlocking component includes a rotating rod, which is rotatably connected inside the flash point meter body, and two pull ropes are fixedly connected to the outside of the rotating rod.

[0011] Furthermore, a locking rod is fixedly connected to one end of the pull rope, and a fixing ring is fixedly connected to the outside of the locking rod.

[0012] Furthermore, a second spring is sleeved on the outside of the locking rod, and two cavities are opened inside the flash point meter body. The two ends of the second spring are fixedly connected to the outer side of the fixing ring and the inner wall of the cavity, respectively, and the outer side of the fixing ring is slidably connected to the inner side of the cavity.

A positioning hole is opened on the inner side of the assembly block, and two assembly slots are opened on the outer side of the flash point meter body. The outer side of the assembly block is engaged with the inner side of the assembly slot, and the outer side of the locking rod is slidably connected to the inner side of the positioning hole.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, by placing the experimental material inside the disc cover and rotating the L-shaped rotating plate to separate the locking block from the locking hole, the L-shaped limiting block moves quickly under the action of the spring force to press down on the top of the disc cover, preventing the disc cover from shaking due to material combustion or other reasons during the experiment, thus affecting the stability of the experiment. When it is not necessary to press down the disc cover, the L-shaped lever is pushed to make the locking block and the locking hole combine to limit the L-shaped limiting block. The operator can flexibly choose whether to press down the disc cover according to actual needs, and freely switch between the two modes, making the overall equipment more flexible to use.

[0016] In this invention, by removing the cover that covers the hemispherical groove on the top of the equipment, the rotating rod is exposed. Then, by rotating the rotating rod and pulling the rope, the locking rod is pulled out from the positioning hole, releasing the restriction on the assembly block, thus easily opening the side cover door. Compared with the traditional bolt fastening method that requires tools and is cumbersome and time-consuming, this design of rotating rod and rope can quickly unlock the side cover door with just a simple rotation operation, making maintenance and repair convenient.
