Description

Technical Field

[0001] This utility model relates to the field of chemical instrument technology, and more specifically, to a crucible tong. Background Technology

[0002] In the laboratory, crucible tongs are generally used to hold crucibles, crucible lids, evaporating dishes and other vessels that need to be ignited and heated. Traditional crucible tongs are generally scissor-shaped and come in various sizes such as long, medium and short.

[0003] For some chemical materials, when heated in a crucible, they will splash after reaching a certain temperature. When the crucible is transferred using existing crucible tongs, the residual heat generated by the crucible will continue to heat the chemical materials. The heat carried by the splashed chemical materials can damage the surrounding environment or organisms. Utility Model Content

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment of the present invention provides a crucible tong, including a connecting rod 1, a clamping member 2, a moving rod 3, and a baffle assembly 4; the connecting rod 1 is provided with a sliding groove; the clamping member 2 is located at the end of the connecting rod 1 and is used to clamp a crucible 10; the moving rod 3 is slidably connected to the sliding groove; the baffle assembly 4 is located at the end of the moving rod 3 near the clamping member 2. The connecting rod 1 is for gripping by hand, and by moving the connecting rod 1, the clamping member 2 clamps the crucible, and then the moving rod 3 is pushed to move, so that the baffle assembly 4 blocks the opening of the crucible.

[0032] like Figure 5 As shown, in one of the optional embodiments of this example, the baffle assembly 4 includes a baffle 41, a fixing block 42, and a fastener 43; the baffle 41 is fixedly connected to the fixing block 42, and the fastener 43 is fastened to the fixing block 42 and the moving rod 3.

[0033] like Figure 5 As shown, in one optional embodiment of this invention, the end of the moving rod 3 near the clamping member 2 is provided with a connecting block 31. The connecting block 31 has an adjustment groove 311, and the fastener 43 passes through the adjustment groove 311 to securely connect the fixing block 42 and the connecting block 31. By adjusting the connecting block 31 to the position corresponding to the adjustment groove 311 and locking the fastener 43, the height of the baffle 41 can be adjusted to accommodate crucibles of different heights.

[0034] like Figure 4 As shown, in one optional embodiment of this invention, the slide rail includes a first groove 11 and a second groove 12. The moving rod 3 includes a rod body 32, a first slider 33, and a second slider 34. The first slider 33 and the second slider 34 are spaced apart and both are fixedly connected to the rod body 32. The first slider 33 is slidably connected to the first groove 11, and the second slider 34 is slidably connected to the second groove 12. Specifically, the first slider 33 and the second slider 34 are preferably sliders with a T-shaped cross-section. Correspondingly, the first groove 11 and the second groove 12 are preferably slide rails with a T-shaped cross-section to limit the movement of the moving rod, so that the moving rod can only move along the length direction of the slide rail.

[0035] In one optional embodiment of this invention, the clamping member 2 includes a connector 21 and a clamping portion 22 fixedly connected to the connector 21. The clamping portion 22 has a first clamping groove 221 and a second clamping groove 222 that are interconnected. Specifically, the diameter of the first clamping groove 221 is smaller than the diameter of the second clamping groove 222. By using clamping grooves with different diameters, it is possible to adapt to the clamping of crucibles of different sizes.

[0036] In one optional embodiment of this invention, the connector 21 is threadedly connected to the connecting rod 1. The threaded connection facilitates disassembly, allowing the clamping component to be removed from the connecting rod 1.

[0037] In one optional embodiment of this invention, the end of the connecting rod 1 facing away from the clamping member 2 is provided with a first handle 13. Preferably, the first handle 13 is covered with heat-insulating material and anti-slip material, and more preferably with rubber material.

[0038] In one optional embodiment of this invention, the end of the moving rod 3 facing away from the baffle assembly 4 is provided with a second handle 35. Preferably, the second handle 35 is covered with heat-insulating material and anti-slip material, and more preferably with rubber material.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
