[0027] By setting up the main case 1, the raw materials for the production of silicon carbide ceramic inner cylinder can be calcined; by setting up the control box 2, the staff can control the calcination of the main case 1 by operating the control panel on the control box 2; by setting up the machine cover 3, the main case 1 can be closed; by setting up the first handle 4 and the second handle 6, it is convenient for the staff to hold the machine cover 3 with both hands respectively to exert force; by setting up the plug block 5, the socket 7 and the lock tongue 8, the plug block 5 can be inserted into the socket 71, and the lock tongue 8 can slide in the installation cavity 72, so as to be inserted into the lock hole 51 to lock the plug block 5, and then lock the machine cover 3, and the locking effect is good; by setting up the pull rod 9 and the handle 11, the handle 11 can be pulled to control the lock tongue 8, withdraw the lock tongue 8 from the lock hole 51, release the plug block 5, and thus open the machine cover 3, and the operation is simple and convenient; by setting up the spring 10, the lock tongue 8 can be reset so that one end of the lock tongue 8 remains in the socket 71, and no manual reset is required.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the handle 11 is arranged on the inner side of the second handle 6, and a gap is provided between the handle 11 and the second handle 6. When the staff holds the second handle 6, the fingers can naturally hold the handle 11, and it is convenient to exert force to pull the handle 11, so that the handle 11 moves inside the second handle 6.

[0029] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the bottom of the plug block 5 is provided with a contact head 52, which is any one of a bevel head and a round head, and the top of the lock tongue 8 is provided with a bevel 81 that matches the contact head 52. By providing the contact head 52 and the bevel 81, the cover 3 can be conveniently closed. When the cover 3 is closed, the plug block 5 can automatically push the lock tongue 8 and press the lock tongue 8 into the installation cavity 72, and then the side wall of the plug block 5 abuts against the lock tongue 8 and continues to slide downward until the cover 3 is completely closed, the lock tongue 8 is aligned with the lock hole 51, and the lock tongue 8 pops out from the installation cavity 72 and inserts into the lock hole 51 under the action of the spring 10, so as to prevent the plug block 5 and the cover 3 from shaking.

[0030] like Figure 3 As shown, the width of the insertion hole 71 is greater than the thickness of the plug block 5, which can ensure that the plug block 5 can be smoothly inserted into the insertion hole 71. The bottom surface of the lock hole 51 is tightly attached to the bottom of the lock tongue 8, which can prevent the cover 3 from shaking up and down.

[0031] like Figure 1 and Figure 2 As shown, the length of the first handle 4 is greater than or equal to the length of the second handle 6, and a gap is provided between the first handle 4 and the second handle 6.

By providing the spring groove 82, when the handle 11 is pulled to make the lock tongue 8 compress the spring 10, the spring 10 can be accommodated, so as to prevent the lock tongue 8 from excessively squeezing and damaging the spring 10.

[0033] Example 2

[0034] Figure 6 This is another embodiment of the utility model, which is different from the first embodiment in that two sets of pull rods 9 are provided in parallel, and the two sides of the other end of the lock tongue 8 are respectively connected to the two ends of the handle 11 through a set of pull rods 9. It is more convenient for the staff to hold and pull the handle 11.

[0035] When closing the cover 3, the staff can directly press down the first handle 4, and the contact head 52 of the plug block 5 abuts against the inclined surface 81 of the lock tongue 8. As the plug block 5 is pressed down, the contact head 52 slides on the inclined surface 81, and the lock tongue 8 is pressed into the installation cavity 72. Then, the end of the lock tongue 8 abuts against the side wall of the plug block 5 and the plug block 5 continues to move downward until the cover 3 is completely closed, the lock tongue 8 is aligned with the lock hole 51, and the lock tongue 8 pops out from the installation cavity 72 and inserts into the lock hole 51 under the action of the spring 10 to complete the locking. When closing, the staff can also directly hold the second handle 6 and the handle 11 and pull the handle 11 to lock the cover 3. The tongue 8 is retracted into the installation cavity 72, and then the cover 3 is closed by the first handle 4. After closing, the handle 11 is released to insert the lock tongue 8 into the lock hole 51 to complete the locking; when opening the cover 3, the staff can hold the first handle 4 and the second handle 6 with both hands respectively. When holding the second handle 6, the fingers can naturally hold the handle 11, and at the same time, the handle 11 is pulled with force. Under the action of the pull rod 9, the lock tongue 8 is separated from the lock hole 51 and retracted into the installation cavity 72. At this time, the staff can push up the first handle 4 to open the cover 3. As the cover 3 is opened, the plug block 5 is separated from the plug hole 71, and the two-hand operation can be more easily exerted. The utility model can not only efficiently fix the cover 3, but also facilitate operation, effectively improving the use effect of the raw material calcining device.
