Description

Technical Field

[0001] The utility model relates to the field of crucible clamps, in particular to a crucible loading and unloading clamp. Background Art

[0002] Crucibles made of high-temperature resistant materials such as quartz and ceramics have high heat resistance and are therefore often used as heating containers. They can be used in laboratories, industries, small workshops and other fields.

[0003] If the crucible is used in the industrial field, a heating mechanism (such as an electromagnetic heating mechanism) is usually provided on the outside of the crucible, and the size of the crucible is relatively large, so that a large number of iron materials of different sizes can be melted into molten iron at one time. In order to output the molten iron from the above-mentioned crucible, the crucible will be set on a bracket with an adjustable crucible tilt angle, and the tilt of the crucible will be controlled by the bracket, and then the molten iron will be output and fall into a small-sized crucible, so that the staff can transfer the small-sized crucible to inject the molten iron into the mold to realize the production of iron products. There are many types of the above-mentioned larger-sized crucibles, such as a crucible for melting iron raw materials disclosed in a Chinese patent with publication number CN118241310A.

[0004] If it is applied to a small workshop, or if an individual wants to melt molten iron to make some objects, a small-sized crucible is usually used to melt the iron material. Specifically, some iron materials are put into the crucible, and the crucible is placed on a burning furnace to increase the temperature of the crucible to achieve the melting of the iron material. After the iron material is completely melted, the staff uses a crucible tongs to clamp the crucible and remove it from the furnace. If the iron material continues to be melted, or the molten iron is not used up, the staff is required to use furniture to clamp the crucible and install it on the furnace. In summary, the staff can achieve the loading and unloading of the crucible by clamping the crucible with a clamp. There are many types of clamps mentioned above, such as a crucible tongs disclosed in a Chinese patent with patent number CN212189176U, which includes a handle portion and a clamping portion, and the handle portion and the clamping portion of the crucible tongs are both provided with a heat-insulating and anti-slip layer for heat insulation and increased clamping friction.

[0005] As mentioned above, the existing clamps for small-sized crucibles are mainly scissor-shaped structures. The staff can generally only hold the handle with one hand, but one hand cannot control the clamp to tightly clamp the crucible. Therefore, the staff's other hand will hold the middle part between the clamp and the handle, and both hands need to hold the clamp for a long time until the molten iron fills the mold. Because the clamp is thin, the above operation will cause discomfort to the palm, which is very obvious in the continuous production of iron products. Utility Model Content

[0024] Example 1

[0025] In the background technology, a clamp for loading and unloading a crucible from a furnace is introduced, and the defects of the existing clamp when used in a small workshop or an individual to melt molten iron to produce iron are pointed out. Specifically, after the crucible is unloaded from the furnace by the existing clamp, the staff needs to hold the grip of the clamp for a long time in order to transfer the crucible more stably to pour the molten iron into the mold. This method easily causes discomfort to the staff's palm. In order to solve this problem, this embodiment provides a new crucible loading and unloading clamp, and the specific technical solution is shown below.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the crucible loading and unloading fixture includes a holding portion 2 and a clamping portion 3, the holding portion 2 includes a supporting column 23, a disk body is fixedly provided at the end of the supporting column 23 adjacent to the clamping portion 3, the diameter of the disk body is larger than the diameter of the supporting column 23, and the length is much smaller than the length of the supporting column 23, the clamping portion 3 includes an adjusting mechanism, two clamping plates 36 and two supporting plates 32, the clamping plates 36 and the supporting plates 32 are opposite to each other, that is, the two supporting plates 32 are respectively arranged at the ends of the two clamping plates 36, and the end of the support plate 32 away from the clamping plate 36 is hingedly connected to the connecting plate 25 on the disk body through an axle, the adjusting mechanism is arranged through the supporting column 23, and the end protruding from the supporting column 23 is hingedly connected to the two support plates 32. When using the clamp to clamp the crucible 1, the staff operates the regulating mechanism to change the state of the regulating mechanism, thereby changing the angle between the two support plates 32, providing convenience for the clamping plate 36 to be sleeved on the crucible 1 and to tightly clamp the crucible 1, changing the current situation where the staff needs to use their palms to hold the gripping part of the clamp and other parts to force the clamp to tightly clamp the crucible 1, and avoiding discomfort in the palm of the user due to long-term use of the clamp to clamp the crucible 1.

[0027] like Figure 3 , Figure 4As shown, in order to make the clamping plate 36 clamp the crucible 1 tightly, the regulating mechanism includes a pulling member 31, a driving member 34 and two inclined plates 35. The end of the pulling member 31 is connected to the driving member 34. The two inclined plates 35 are hingedly connected to the driving member 34 and are distributed on both sides of the driving member 34. A mounting hole 33 is provided on the support plate 32. The mounting hole 33 is arranged along the length direction of the support plate 32. One end of the inclined plate 35 away from the driving member 34 is hingedly arranged in the mounting hole 33, and the end of the driving member 34 can extend into the mounting hole 33. A through hole 24 is provided through the support column 23, and the pulling member 31 is arranged through the through hole 24. When it is necessary to make the clamping plate 36 clamp the crucible 1 tightly, the staff operates the pulling member 31 to move, forcing the driving member 34 to move, changing the inclination angle of the inclined plate 35 relative to the support column 23, thereby reducing the angle between the two support plates 32, and the clamping plate 36 clamps the crucible 1 tightly. After the pulling member 31 is adjusted, it can be stably placed relative to the supporting column 23 so that the clamping plate 36 can firmly clamp the crucible 1 for a long time.

[0028] like Figure 2 As shown, the outer side of the support column 23 is sleeved with a sleeve 22, and a rotating frame 21 is detachably provided at one end of the support column 23 away from the clamping part 3. The pulling member 31 is set as a rope, and the driving member 34 is set as a cross plate structure. Two inclined plates 35 are hinged at both ends of the cross plate structure. The rope passes through the perforation 24, and the end is fixedly connected to the driving member 34. When the clamping plates 36 are distributed on both sides of the crucible 1, the staff can pull the pull rope so that the end of the rope is tightly wound on the rotating frame 21 or the end of the support column 23, so as to control the movement of the driving member 34 and make the clamping plate 36 tightly clamp the crucible 1. When the clamp clamps the crucible and moves to the side of the mold 1, the staff holds the sleeve 22 with one hand and the rotating frame 21 with the other hand, and can control the rotation of the support column 23 relative to the sleeve 22, adjust the inclination angle of the clamping plate 36 and the crucible 1, and provide convenience for pouring molten iron into the mold.

[0029] Example 2

[0030] In the background technology, a clamp for loading and unloading a crucible from a furnace is introduced, and the defects of the existing clamp when used in a small workshop or an individual to melt molten iron to produce iron are pointed out. Specifically, after the crucible is unloaded from the furnace by the existing clamp, the staff needs to hold the grip of the clamp for a long time in order to transfer the crucible more stably to pour the molten iron into the mold. This method easily causes discomfort to the staff's palm. In order to solve this problem, this embodiment provides a new crucible loading and unloading clamp, and the specific technical solution is shown below.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the crucible loading and unloading fixture includes a holding portion 2 and a clamping portion 3, the holding portion 2 includes a supporting column 23, a disk body is fixedly provided at the end of the supporting column 23 adjacent to the clamping portion 3, the diameter of the disk body is larger than the diameter of the supporting column 23, and the length is much smaller than the length of the supporting column 23, the clamping portion 3 includes an adjusting mechanism, two clamping plates 36 and two supporting plates 32, the clamping plates 36 and the supporting plates 32 are opposite to each other, that is, the two supporting plates 32 are respectively arranged at the ends of the two clamping plates 36, and the end of the support plate 32 away from the clamping plate 36 is hingedly connected to the connecting plate 25 on the disk body through an axle, the adjusting mechanism is arranged through the supporting column 23, and the end protruding from the supporting column 23 is hingedly connected to the two support plates 32. When using the clamp to clamp the crucible 1, the staff operates the regulating mechanism to change the state of the regulating mechanism, thereby changing the angle between the two support plates 32, providing convenience for the clamping plate 36 to be sleeved on the crucible 1 and to tightly clamp the crucible 1, changing the current situation where the staff needs to use their palms to hold the gripping part of the clamp and other parts to force the clamp to tightly clamp the crucible 1, and avoiding discomfort in the palm of the user due to long-term use of the clamp to clamp the crucible 1.
