Abstract
Description
A high-temperature clamp for laboratory use Technical Field
[0001] This utility model relates to the field of laboratory equipment technology, specifically a high-temperature clamp for laboratory use. Background Technology
[0002] When performing operations such as ash separation or burn-off in a muffle furnace, a high-temperature clamp that can extend into the muffle furnace is generally used to facilitate the removal of the sample fired in the furnace from the high temperature, thus avoiding burns to the hands from the high temperature inside the furnace when taking the sample.
[0003] During the design process of this utility model, the following problems were discovered in the existing technology:
[0004] After ash separation or burn-off operations, muffle furnaces often use exposed metal clamps for sampling. Due to the high temperature inside the furnace, the clamps are easily overheated during sampling, which can burn hands. The clamps also have poor heat insulation. Furthermore, existing clamps rely heavily on the operator's hand strength for sampling. When the object being clamped is heavy, the operator's hands may become sore and unstable, increasing the risk of the object falling. This makes the clamping operation inconvenient. Summary of the Invention
[0005] The purpose of this invention is to provide a high-temperature clamp for laboratory use to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a laboratory high-temperature clamp, including a left clamp, the outer wall of the left clamp being installed and connected to the inner wall of the right clamp, a rotating shaft being provided on the left clamp, the outer wall of the rotating shaft being rotatably connected to the inner wall of a rotating cap, and the rotating cap being provided on the right clamp;
[0007] Both the left and right clamps are equipped with chucks at their front ends. Both the left and right clamps are equipped with mounting grooves on the inner sidewalls of their rear ends. Springs are installed inside the mounting grooves. Both the left and right clamps are equipped with handles at their rear ends. The outer side of the handles is covered with a heat-insulating leather sleeve.
[0008] More preferably, the left clamp and the right clamp are arranged symmetrically, and the left clamp is mounted in the rotating cap through a rotating shaft and is rotatably connected to the right clamp.
[0009] More preferably, the left and right clamps are both set as semi-circular arcs near the front clamp, and the ends away from the clamp are straight sections.
[0010] More preferably, the left clamp and the right clamp are bent at the rotating shaft and the rotating cap respectively, the front end of the rotating shaft and the rotating cap is a straight section, and the rear end of the rotating shaft and the rotating cap is an arc section.
[0011] More preferably, the two ends of the spring are mounted and connected to the inner walls of the left and right clamps by being placed inside the mounting groove.
[0012] More preferably, the clamps are flat, tweezer-shaped, and symmetrically arranged at the front ends of the left and right clamps respectively.
[0013] More preferably, the handle is an arc shape symmetrically disposed at the rear ends of the left and right clamps respectively.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] This clamp utilizes springs between the two clamps for assisted gripping. By gripping the handle and applying pressure inward, the springs are simultaneously compressed and retracted. Once the clamp is engaged, releasing the springs releases their kinetic energy, which in turn causes the clamps to apply a gripping force to the sample. This makes the clamping process easier and more stable for the user. The handles of both clamps are wrapped with heat-insulating leather sleeves. When in use, gripping the handles tightly with both hands effectively isolates the heat transferred from the metal clamps during gripping, thus preventing the risk of burns from high temperatures.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0021] Please refer to Figures 1 to 3. This utility model provides a technical solution: a high-temperature clamp for laboratory use, including a left clamp 1, the outer wall of the left clamp 1 is installed and connected to the inner wall of the right clamp 2, a rotating shaft 3 is provided on the left clamp 1, the outer wall of the rotating shaft 3 is rotatably connected to the inner wall of the rotating cap 4, and the rotating cap 4 is provided on the right clamp 2.
[0022] Both the left clamp 1 and the right clamp 2 are equipped with a chuck 5 at their front ends. Both the left clamp 1 and the right clamp 2 are equipped with an installation groove 6 on the inner side wall of their rear ends. A spring 7 is installed inside the installation groove 6. Both the left clamp 1 and the right clamp 2 are equipped with a handle 8 at their rear ends. The outside of the handle 8 is covered with a heat-insulating leather sleeve 9.
[0023] In this embodiment, as shown in Figures 1, 2 and 3, the left clamp 1 and the right clamp 2 are symmetrically arranged, and the left clamp 1 is mounted in the rotating cap 4 through the rotating shaft 3 and is rotatably connected to the right clamp 2.
[0024] In this embodiment, as shown in Figures 1 and 2, the left clamp 1 and the right clamp 2 are both set as semi-circular arcs near the front clamp 5, and the end away from the clamp 5 is a straight section.
[0025] In this embodiment, as shown in Figures 1, 2 and 3, the left clamp 1 and the right clamp 2 are bent at the rotating shaft 3 and the rotating cap 4, respectively. The front ends of the rotating shaft 3 and the rotating cap 4 are straight sections, and the rear ends of the rotating shaft 3 and the rotating cap 4 are arc sections.
[0026] In this embodiment, as shown in Figures 1 and 2, the two ends of the spring 7 are connected to the inner sidewalls of the left clamp 1 and the right clamp 2 by being placed inside the mounting groove 6.
[0027] In this embodiment, as shown in Figures 1 and 2, the clamps 5 are flat tweezers shaped and symmetrically arranged at the front ends of the left clamp 1 and the right clamp 2 respectively.
[0028] In this embodiment, as shown in Figures 1 and 2, the handle 8 is an arc shape symmetrically arranged at the rear ends of the left clamp 1 and the right clamp 2 respectively.
[0029] As shown in process diagrams 1, 2, and 3, this laboratory high-temperature fixture operates as follows:
[0030] First, grip the heat-insulating leather sleeve 9 on the handle 8 with both hands and apply pressure inwards simultaneously. At this time, the rotating shaft 3 rotates within the rotating cap 4, thereby opening the front end of the left clamp 1 and right clamp 2 under the pressure from both sides. Simultaneously, the rear end of the clamp applies pressure inwards, compressing the spring 7 through the mounting groove 6, and clamping it through the front chuck 5. Different types of samples can be clamped through the front chuck 5 and the arc at the front end of the clamp. When clamping a sample, release the pressure from both sides of the clamp and the spring 7 to release the kinetic energy of the retraction, and the sample will be clamped securely. This makes the clamping process more effortless and convenient for the user to perform clamping and sampling operations. When holding the handle 8, the heat-insulating leather sleeve 9 on the outer layer of the handle 8 can effectively isolate the heat transmitted by the metal to prevent burns to the hands.
