[0023] Reference Figure 1-Figure 4 A combined high temperature resistant crucible comprises a main crucible 1 and an auxiliary crucible 2. A through hole is provided at the bottom of the auxiliary crucible 2. A plurality of mounting plates 3 are fixedly installed on the side wall of the auxiliary crucible 2 in a circumferential shape. A U-shaped mounting seat 4 is provided at one end of the mounting plate 3 away from the auxiliary crucible 2. A slide groove 5 is provided on the surface of the mounting seat 4. One end of the plurality of mounting plates 3 is respectively vertically slidably arranged in the plurality of slide grooves 5 and locked by a locking assembly.

[0024] The side wall of the main crucible 1 is circumferentially fixed with a plurality of mounting blocks 6, a through hole is provided on the surface of the mounting seat 4, a locking rod 7 is slidably inserted in the through hole, the locking rod 7 is connected to the mounting seat 4 through a telescopic component, the telescopic component includes a telescopic spring 9 sleeved on the locking rod 7, one end of the locking rod 7 is fixedly installed with a placement block, the two ends of the telescopic spring 9 are respectively fixedly connected to the placement block and the mounting seat 4, and a locking groove 8 for inserting the end of the locking rod 7 is provided on the surface of the mounting block 6;

[0025] When the main crucible 1 and the auxiliary crucible 2 need to be installed, first align the multiple mounting seats 4 with the multiple mounting blocks 6 respectively and make them butt against each other. At this time, the multiple locking rods 7 will correspond to the positions of the multiple locking grooves 8 respectively, and then control the ends of the locking rods 7 to be inserted into the locking grooves 8 to complete the installation of the main crucible 1 and the auxiliary crucible 2. When disassembling, just control the locking rods 7 to move, the telescopic springs 9 will shrink, and the ends of the locking rods 7 will be moved out of the locking grooves 8, so that the auxiliary crucible 2 can be quickly unlocked, which is convenient and quick.

[0026] When the height position of the auxiliary crucible 2 needs to be adjusted, the locking assembly on the mounting plate 3 can be released to adjust the height position of the auxiliary crucible 2. After moving to a suitable position, the mounting plate 3 can be locked by the locking assembly. There is no need to release the installation between the auxiliary crucible 2 and the main crucible 1 and then adjust the height position of the auxiliary crucible 2.

[0027] The locking assembly includes two first spring rods 10. The upper surface of one end of the mounting plate 3 located in the slide groove 5 is symmetrically provided with mounting grooves. The two first spring rods 10 are respectively and horizontally fixedly installed in the two mounting grooves. The left and right groove walls of the slide groove 5 are equidistantly provided with a plurality of sockets 11 for inserting the ends of the first spring rods 10. An L-shaped push plate 12 is fixedly sleeved on the first spring rod 10, and the surface of the push plate 12 is provided with anti-slip grooves.

[0028] When the height of the auxiliary crucible 2 needs to be adjusted, the plurality of first spring rods 10 are controlled to contract by controlling the movement of the plurality of push plates 12, so that the ends of the plurality of first spring rods 10 are respectively moved out of the plurality of sockets 11, thereby releasing the lock on the auxiliary crucible 2. Then, the auxiliary crucible 2 is controlled to move vertically until it moves to a suitable position. At this time, the locking block push plate 12 is released, and the plurality of first spring rods 10 will quickly recover, and their ends will be respectively inserted into the sockets 11 corresponding to their own positions, thereby completing the locking of the auxiliary crucible 2.

[0029] An inclined plate 13 is fixedly mounted on the upper surface of the push plate 12, a plurality of second spring rods 14 are fixedly mounted on the upper surface of the auxiliary crucible 2, an L-shaped connecting rod 17 is fixedly mounted on the top of the second spring rod 14, a circular ring 15 is fixedly mounted on one end of the plurality of connecting rods 17, a plurality of pairs of trapezoidal pressing plates 16 are fixedly mounted on the lower surface of the circular ring 15, and the inclined surfaces of the plurality of pressing plates 16 are respectively arranged face to face with the inclined surfaces of the plurality of inclined plates 13;

[0030] When it is necessary to control the multiple second spring rods 14 to retract, it is only necessary to move the control ring 15 downward. At this time, the inclined surfaces of the multiple pressure plates 16 will slide in contact with the inclined surfaces of the multiple inclined plates 13 respectively. Under the action of the inclined surface pressure, the multiple second spring rods 14 will retract together. There is no need to control the retraction of the multiple second spring rods 14 one by one, which is convenient and quick.

[0031] The lower surface of the mounting seat 4 is fixedly mounted with an insertion rod 18, and the upper surface of the mounting block 6 is vertically provided with a guide hole for inserting the insertion rod 18;

[0032] When installing the auxiliary crucible 2 with the main crucible 1, multiple insertion rods 18 can be aligned with the multiple guide holes and inserted. When the multiple mounting seats 4 and the multiple mounting blocks 6 are abutted, the multiple locking rods 7 will respectively correspond to the positions of the multiple locking grooves 8, and there is no need to spend time to align the positions of the mounting seats 4 and the mounting blocks 6. At the same time, when the insertion rods 18 are inserted into the guide holes, they can also have a certain locking effect. Even if the end of the locking rod 7 is moved out of the locking groove 8, the auxiliary crucible 2 will not be separated from the main crucible 1.

[0033] In the utility model, when it is necessary to install the main crucible 1 and the auxiliary crucible 2, firstly, the multiple mounting seats 4 are respectively aligned with the multiple mounting blocks 6 and made to abut against each other. At this time, the multiple locking rods 7 will respectively correspond to the positions of the multiple locking grooves 8, and then the ends of the locking rods 7 are controlled to be inserted into the locking grooves 8, so that the installation of the main crucible 1 and the auxiliary crucible 2 can be completed. When disassembling, it is only necessary to control the movement of the locking rods 7, and the telescopic parts will shrink, so that the ends of the locking rods 7 are moved out of the locking grooves 8, and the auxiliary crucible 2 can be quickly unlocked, which is convenient and quick. When it is necessary to adjust the height position of the auxiliary crucible 2, the locking assembly can be released from the mounting plate 3, so that the height position of the auxiliary crucible 2 can be adjusted. After moving to a suitable position, the mounting plate 3 can be locked by the locking assembly. There is no need to release the installation between the auxiliary crucible 2 and the main crucible 1, and then adjust the height position of the auxiliary crucible 2, which improves practicality.

[0034] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
